There is probably no person who has never experienced high blood pressure throughout his life. Hypertension can be short-term - caused by severe stress or excessive physical exertion. But in many people, hypertension becomes chronic, and then during diagnosis, doctors must determine the degree of arterial hypertension (AH) and assess potential health risks.
What is arterial hypertension
Pressure in the arteries of the systemic circulation plays an important role in human life. If it is constantly elevated, this is arterial hypertension. Depending on the degree of increase in systolic and diastolic pressure, 4 stages of arterial hypertension are distinguished. In the initial stages, the disease is asymptomatic.
Causes
The first degree of arterial hypertension often develops due to improper lifestyle. Lack of sleep, nervous tension and bad habits provoke vasoconstriction. Blood begins to press on the arteries with greater force, which leads to hypertension. Factors that provoke the appearance of primary and secondary hypertension include:
- physical inactivity;
- obesity;
- hereditary predisposition;
- vitamin D deficiency;
- sodium sensitivity;
- hypokalemia;
- elevated cholesterol levels;
- the presence of chronic diseases of internal organs.
Classification
The disease is divided depending on the causes of its development and blood pressure levels. Based on the nature of the disease, primary and secondary hypertension are distinguished. With primary, or essential arterial hypertension, patients’ blood pressure simply rises, but there are no pathologies of the internal organs. There are several types of it: hyperadrenergic, hyporeninic, normoreninic, hyperreninic. The main problem in the treatment of primary hypertension is that the causes of its occurrence have not yet been studied.
The classification of secondary hypertension is as follows:
- neurogenic;
- hemodynamic;
- endocrine;
- medicinal;
- nephrogenic.
With the neurogenic type of the disease, patients experience problems in the peripheral and central nervous systems caused by brain tumors, circulatory failure or stroke. Hemodynamic symptomatic hypertension is accompanied by heart disease and aortic pathologies. The endocrine form of the disease can be caused by active work of the adrenal glands or thyroid gland.
Nephrogenic hypertension is considered the most dangerous, because often accompanied by polycystic disease, pyelonephritis and other kidney pathologies. The dosage form occurs against the background of uncontrolled use of medications that affect vascular density or the functioning of the endocrine system.
Degrees of hypertension - table
Currently, when examining patients with suspected hypertension, the Korotkoff method is used. This method of examining patients was officially approved by the World Health Organization (WHO) in 1935. Before diagnosing a patient with any degree of arterial hypertension, pressure measurements are taken on each arm 3 times. A difference of 10-15 mm indicates pathology of peripheral vessels. Degrees of hypertension in relation to blood pressure indicators:
Blood pressure (BP) |
Systolic blood pressure |
Diastolic blood pressure |
Optimal |
||
Normal |
||
Upper limit of normal |
||
AH 1st degree |
||
AH 2 degrees |
||
AH 3 degrees |
||
4th degree hypertension |
||
Isolated systolic hypertension |
Risk stratification for arterial hypertension
All patients are divided into several groups depending on their health status and degree of hypertension. Stratification (risk assessment) is influenced not only by blood pressure, but also by the patient’s age and lifestyle. The main risk factors include dyslipidemia, a family history of early development of cardiovascular diseases, excess C-reactive protein, abdominal obesity, and smoking. In addition, take into account:
- impaired glucose tolerance;
- high levels of fibrinogen;
- physical inactivity;
- presence of diabetes mellitus;
- target organ damage;
- diseases of the endocrine system;
- the appearance of signs of thickening of the arteries;
- kidney and heart diseases;
- circulatory disorders.
In women, the chances of getting complications increase after 65 years of age, in men - earlier, at 55 years of age. The risk of complications will be low if the patient is exposed to no more than one or two adverse factors. Such patients almost always have grade 1 hypertension. When assessing the condition of elderly patients (over 65 years of age), doctors rarely indicate low risk in the medical history, because In this age category, the chance of developing vascular atherosclerosis is 80%. They are immediately placed in a high-risk group.
Hypertension 1 degree
The disease is often iatrogenic, i.e. occurs when taking medications containing artificial hormones. Arterial hypertension of the 1st degree can be primary or secondary. The essential form of the disease is accompanied only by increased blood pressure. In the secondary form, the patient’s medical history contains other pathologies that provoke the development of hypertension. The disease often occurs during pregnancy and is asymptomatic in 90% of patients.
Normalization of blood pressure is facilitated by reducing body weight and increasing physical activity. The patient does not need to start heavy and grueling training. Daily 30-minute walks in the fresh air will help you recover from stage 1 arterial hypertension. Hypertensive patients should adjust their diet by excluding too salty and fatty foods from the menu. Liquid intake should be limited for a while. Medicines for the first type of hypertension are not prescribed.
Risk 1
This group includes patients under 55 years of age who suffer from mild high blood pressure. There must be no other risk factors. If blood pressure is normal, non-drug therapy is recommended. It is also suitable for labile arterial hypertension, when the symptoms of the disease appear periodically. Primary prevention of complications includes normalization of body mass index, diet correction and elimination of muscular dystrophy.
Risk 2
Patients suffering from exposure to 2-3 unfavorable factors fall into this group. The first degree of arterial hypertension with risk 2 is characterized by the appearance of the first symptoms of high blood pressure. Patients complain of migraines, spots in the eyes and dizziness. The patient can only get rid of the disease with the help of drug therapy. Complications in patients at moderate risk occur in 15-20% of cases.
Risk 3
Many patients assume that type 1 hypertension is mild and goes away on its own. But without treatment, any person can develop complications. At risk 3, patients experience swelling, lethargy, angina, fatigue, because The kidneys begin to suffer from pathology. Hypertensive crises may occur, characterized by increased heart rate and hand tremors. Further complications develop with a probability of 20-30%.
Risk 4
In this group, cardiovascular complications occur in more than 30% of patients. This risk is diagnosed in a patient if potential aggravating factors are present. These include chronic renal failure, congenital lesions of the blood vessels of the brain and other organs. At risk 4, the disease progresses to the second or third degree within 6-7 months.
Hypertension 2 degrees
A mild form of the disease is accompanied by typical signs of high blood pressure: nausea, fatigue, headache. With grade 2 hypertension, the likelihood of left ventricular hypertrophy increases. The muscles begin to contract more strongly to resist the flow of blood, which leads to the growth of muscle tissue and disruption of the heart. Clinical manifestations of this form of hypertension:
- vascular insufficiency;
- narrowing of arterioles;
- sensation of pulsation in the temples;
- numbness of the limbs;
- pathology of the fundus.
Arterial hypertension of the 2nd degree can be diagnosed if only the diastolic or systolic blood pressure is exceeded. Monotherapy works well for this form of the disease. It is used when high blood pressure does not pose a risk to the patient’s life and does not affect his ability to work. If it is difficult for the patient to work during attacks, treatment with combination drugs is started.
Risk 2
Hypertension is mild. The patient complains of migraine and pain in the heart area. At risk 2, the patient is exposed to one or two unfavorable factors, so the percentage of complications in this group is less than 10. Sensitive people experience skin hyperemia. There are no target organ lesions. Treatment consists of taking one type of antihypertensive medication and adjusting your diet.
Risk 3
Arterial hypertension can be detected by the presence of albumin proteins in the urine. The patient not only swells his limbs, but also his face. A hypertensive patient complains of blurred vision. The walls of blood vessels become thicker. The risk of complications reaches 25%. Treatment consists of taking medications that normalize blood pressure and restore the functioning of organs damaged by the disease.
Risk 4
With an unfavorable course of the disease, symptoms of target organ damage appear. Patients suffer from sudden surges in pressure of 59 units or more. The transition of hypertension to the next stage without treatment will take 2-3 months. In case of persistent impairment of body functions, hypertensive patients with risk 4 are assigned disability groups 2 or 3. The health status continues to deteriorate in 40% of patients.
Hypertension 3 degrees
The systolic pressure at this stage of the disease is equal to or more than 180 mm Hg. Art., and diastolic – 110 mm Hg. and higher. Vascular tissues in the third degree of arterial hypertension are very damaged. Patients often suffer from hypertensive crises and angina. Blood pressure readings are always elevated. The disease is accompanied by the following symptoms:
- dizziness and constant migraines;
- the appearance of spots before the eyes;
- muscle weakness;
- damage to retinal vessels;
- deterioration in vision clarity;
Treatment of high blood pressure in stage 3 hypertension includes drug therapy, diet and exercise. Hypertensive patients must give up smoking and alcohol. Taking one drug will not help cope with high blood pressure in this form of the disease. Doctors prescribe diuretics, calcium channel blockers, and angiotensin-converting enzyme (ACE) inhibitors to patients. The disease is considered resistant if the use of 3-4 drugs failed to normalize the patient’s condition.
Risk 3
The group includes patients who may become disabled. Hypertension of grade 3 with risk of 3 is accompanied by large-scale damage to target organs. The kidneys, heart, brain, and retina suffer from high blood pressure. The left ventricle expands, which is accompanied by growth of the muscle layer. The myocardium begins to lose its elastic properties. The patient develops hemodynamic instability.
Risk 4
The group consists of patients with malignant arterial hypertension. Patients suffer from periodic transient attacks, which leads to the development of severe complications, including stroke. Mortality in this group of patients is high. With increased severity of arterial hypertension, patients are assigned disability group 1.
Hypertension 4 degrees
This stage of hypertension is considered very severe. In 80% of patients, death occurs within a couple of months after the disease transitions to this form. In case of a hypertensive crisis, it is important to quickly provide first aid to the patient. It is necessary to lay it on a flat surface, slightly raise its head. The patient is given antihypertensive tablets that sharply lower blood pressure.
Stage 4 arterial hypertension is characterized by 2 forms of course: primary and secondary. The main difference between this type of disease and others are the complications that accompany attacks. When pressure increases, patients experience disturbances in cerebral, coronary, and renal circulation. The cardiovascular system suffers from constant overload, which leads to disability of the patient.

Table 1
#187; Arterial hypertension #187; Risk stratification for arterial hypertension
Hypertension is a disease in which there is an increase in blood pressure; the reasons for such an increase, as well as changes, may be different.
Risk stratification for arterial hypertension is an assessment system for the likelihood of complications of the disease on the general condition of the heart and vascular system.
The general assessment system is based on a number of special indicators that affect the quality of life and its duration for the patient.
Stratification of all risks for hypertension is based on an assessment of the following factors:
- degree of disease (assessed during examination);
- existing risk factors;
- diagnosing lesions and pathologies of target organs;
- clinic (this is determined individually for each patient).
All significant risks are listed in a special Risk Assessment List, which also contains recommendations for treatment and prevention of complications.
Stratification determines which risk factors can cause the development of cardiovascular diseases, the emergence of a new disorder, or the death of a patient from certain cardiac causes over the next ten years. Risk assessment is performed only after completing a general examination of the patient. All risks are divided into the following groups:
- up to 15% #8212; low level;
- from 15% to 20% #8212; the risk level is average;
- 20-30% #8212; level is high;
- From 30% #8212; the risk is very high.
The prognosis can be influenced by a variety of data, and they will be different for each patient. Factors contributing to the development of arterial hypertension and influencing the prognosis may be the following:
- obesity, increased body weight;
- bad habits (most often smoking, abuse of caffeine-containing products, alcohol), sedentary lifestyle, poor nutrition;
- changes in cholesterol levels;
- tolerance is broken (to carbohydrates);
- microalbuminuria (only for diabetes);
- fibrinogen value is increased;
- there is a high risk for ethnic, socio-economic groups;
- The region is characterized by an increased incidence of hypertension, diseases, and pathologies of the heart and blood vessels.
All risks that affect the prognosis of hypertension, according to WHO recommendations from 1999, can be divided into the following groups:
- Blood pressure rises to grade 1-3;
- age: women – from 65 years, men – from 55 years;
- bad habits (drinking alcohol, smoking);
- diabetes;
- a history of pathologies of the heart and blood vessels;
- serum cholesterol increases from 6.5 mmol per liter.
When assessing risks, attention must be paid to damage and disruption of target organs. These are diseases such as narrowing of the retinal arteries, general signs of the appearance of atherosclerotic plaques, a greatly increased plasma creatinine value, proteinuria, and hypertrophy of the left ventricular region.
Attention should be paid to the presence of clinical complications, including cerebrovascular (this is a transient attack, as well as hemorrhagic/ischemic stroke), various heart diseases (including failure, angina, heart attacks), kidney diseases (including failure, nephropathy), vascular pathologies (peripheral arteries, a disorder such as aneurysm dissection). Among the general risk factors, it is necessary to note the developed form of retinopathy in the form of papilloedema, exudates, and hemorrhage.
All these factors are determined by the observing specialist, who conducts a general risk assessment and makes a prognosis for the course of the disease for the next ten years.
Hypertension is a polyetiological disease, in other words, a combination of many risk factors leads to the development of the disease. therefore, the likelihood of headache occurrence is determined by the combination of these factors, the intensity of their action, and so on.
But as such, the occurrence of hypertension, especially if we talk about asymptomatic forms. does not have much practical significance, since a person can live for a long time without experiencing any difficulties and without even knowing that he is suffering from this disease.
The danger of the pathology and, accordingly, the medical significance of the disease lies in the development of cardiovascular complications.
Previously, it was believed that the likelihood of cardiovascular complications in hypertension was determined solely by blood pressure levels. And the higher the pressure, the greater the risk of complications.
Today, it has been established that the risk of developing complications is determined not only by blood pressure figures, but also by many other factors, in particular, it depends on the involvement of other organs and systems in the pathological process, as well as the presence of associated clinical conditions.
In this regard, all patients suffering from essential hypertension are usually divided into 4 groups, each of which has its own level of risk for developing cardiovascular complications.
1. Low risk. Men and women under 55 years of age who have stage 1 hypertension and no other cardiovascular diseases have a low risk of developing cardiovascular complications, which does not exceed 15%.
2. Average level.
This group includes patients who have risk factors for developing complications, in particular, high blood pressure, high blood cholesterol, impaired glucose tolerance, age over 55 years for men and 65 years for women, and a family history of hypertension. In this case, there is no damage to target organs or associated diseases. The risk of developing cardiovascular complications is 15-20%.
4. Very high risk group. This risk group includes patients who have associated diseases, in particular, coronary heart disease, have had a myocardial infarction, have a history of acute cerebrovascular accident, suffer from heart or kidney failure, as well as people who have a combination of hypertension and diabetes mellitus.
Note:* – presence of criteria 1 and 2
mandatory in all cases. (National
clinical guidelines VNOK, 2010).

*Additional and “new” risk factors (not taken into account when risk stratification).
Risk levels of hypertension:
1. Low risk group (risk 1). This group includes men and women under the age of 55 years with stage 1 hypertension in the absence of other risk factors, target organ damage and associated cardiovascular diseases. The risk of developing cardiovascular complications in the next 10 years (stroke, heart attack) is less than 15%.
2. Medium risk group (risk 2). This group includes patients with grade 1 or 2 hypertension. The main sign of belonging to this group is the presence of 1-2 other risk factors in the absence of target organ damage and associated cardiovascular diseases. The risk of developing cardiovascular complications in the next 10 years (stroke, heart attack) is 15-20%.
3. High-risk group (risk 3). This group includes patients with grade 1 or 2 hypertension who have 3 or more other risk factors or target organ damage. The same group includes patients with grade 3 hypertension without other risk factors, without target organ damage, without associated diseases and diabetes mellitus. The risk of developing cardiovascular complications in this group over the next 10 years ranges from 20 to 30%.
4. Very high risk group (risk 4). This group includes patients with any degree of hypertension with associated diseases, as well as patients with grade 3 hypertension with the presence of other risk factors and/or target organ damage and/or diabetes mellitus, even in the absence of associated diseases. The risk of developing cardiovascular complications in the next 10 years exceeds 30%.

Diagnostics
Diagnostic criteria
Complaints and anamnesis
In a patient with newly diagnosed hypertension, it is necessary careful collection of anamnesis, which should include:
- duration of existence of hypertension and levels of increased blood pressure in the anamnesis, as well as the results of previously used treatment with antihypertensive drugs,
A history of hypertensive crises;
- data on the presence of symptoms of coronary artery disease, heart failure, central nervous system diseases, peripheral vascular lesions, diabetes mellitus, gout, lipid metabolism disorders, broncho-obstructive diseases, kidney diseases, sexual disorders and other pathologies, as well as information on medications used to treat these diseases , especially those that can increase blood pressure;
- identification of specific symptoms that would give reason to assume the secondary nature of hypertension (young age, tremor, sweating, severe treatment-resistant hypertension, murmur over the renal arteries, severe retinopathy, hypercreatininemia, spontaneous hypokalemia);
- in women - gynecological history, connection of increased blood pressure with pregnancy, menopause, taking hormonal contraceptives, hormone replacement therapy;
- a thorough assessment of lifestyle, including consumption of fatty foods, table salt, alcoholic beverages, quantitative assessment of smoking and physical activity, as well as data on changes in body weight throughout life;
- personal and psychological characteristics, as well as environmental factors that could influence the course and outcome of treatment of hypertension, including marital status, situation at work and in the family, level of education;
- family history of hypertension, diabetes mellitus, lipid metabolism disorders, coronary heart disease (CHD), stroke or kidney disease.
Physical examination:
1. Confirming the presence of hypertension and establishing its stability (an increase in blood pressure above 140/90 mm Hg in patients who do not receive regular antihypertensive therapy as a result of at least three measurements in different settings).
2. Exclusion of secondary arterial hypertension.
3. Risk stratification of hypertension (determining the degree of increase in blood pressure, identifying avoidable and irreducible risk factors, target organ damage and associated conditions).
Laboratory research: hemoglobin, red blood cells, fasting blood glucose, total cholesterol, HDL cholesterol, fasting triglycerides, uric acid, creatinine, potassium, sodium, urinalysis.
Instrumental studies: echocardiography, ultrasound of the carotid and femoral arteries, ultrasound of the kidneys, Doppler ultrasound of the renal vessels, ultrasound of the adrenal glands, radioisotope renography.
Indications for specialist consultation: according to indications.
Differential diagnosis: no.
List of main diagnostic measures:
1. Assessment of medical history (family history of hypertension, kidney disease, early development of coronary artery disease in close relatives; indication of a stroke, myocardial infarction; hereditary predisposition to diabetes mellitus, lipid metabolism disorders).
2. Assessment of lifestyle (nutrition, consumption of table salt, physical activity), nature of work, marital status, family environment, psychological characteristics of the patient.
3. Examination (height, body weight, body mass index, type and degree of obesity if present, identification of signs of symptomatic hypertension - endocrine stigmas).
4. Measure blood pressure repeatedly under different conditions.
5. ECG in 12 leads.
6. Fundus examination.
7. Laboratory examination: hemoglobin, red blood cells, fasting blood glucose, total cholesterol, HDL cholesterol, fasting triglycerides, uric acid, creatinine, potassium, sodium, urinalysis.
8. Due to the high prevalence of hypertension in the population, screening for the disease should be performed as part of routine examination for other conditions.
9. Screening for hypertension is especially indicated in individuals with risk factors: a family history of hypertension, hyperlipidemia, diabetes mellitus, smoking, obesity.
10. In persons without clinical manifestations of hypertension, annual blood pressure measurements are required. Further frequency of blood pressure measurements is determined by the initial indicators.
List of additional diagnostic measures
As additional instrumental and laboratory tests, if necessary - echocardiography, ultrasound of the carotid and femoral arteries, ultrasound of the kidneys, Doppler ultrasound of the renal vessels, ultrasound of the adrenal glands, radioisotope renography, C-reactive protein in the blood by quantitative method, microalbuminuria test strips (required for diabetes mellitus) diabetes), quantitative proteinuria, urine analysis according to Nechiporenko and Zimnitsky, Rehberg test.
Treatment
Treatment tactics
Treatment goals:
1. The goal of treatment is to reduce blood pressure to the target level (in young and middle-aged patients - below< 130 / 85, у пожилых пациентов - < 140 / 90, у больных сахарным диабетом - < 130 / 85). Даже незначительное снижение АД при терапии необходимо, если невозможно достигнуть «целевых» значений АД. Терапия при АГ должна быть направлена на снижение как систолического, так и диастолического артериального давления.
2. Prevention of the occurrence of structural and functional changes in target organs or their reverse development.
3. Prevention of the development of cerebrovascular accidents, sudden cardiac death, heart and kidney failure and, as a result, improved long-term prognosis, i.e. patient survival.
Non-drug treatment
Changing the patient's lifestyle
1. Non-drug treatment should be recommended for all patients with hypertension, including those who require drug therapy.
2. Non-drug therapy reduces the need for drug therapy and increases the effectiveness of antihypertensive drugs.
6. Patients with excess body weight (BMI: 25.0 kg/m2) should be advised to lose weight.
7. It is necessary to increase physical activity through regular exercise.
8. The consumption of table salt should be reduced to a level of less than 5-6 g per day or sodium to a level of less than 2.4 g per day.
9. The consumption of fruits and vegetables should be increased, and foods containing saturated fatty acids should be reduced.
Drug treatment:
1. Use drug therapy promptly in patients at “high” and “very high” risk for cardiovascular events.
2. When prescribing drug therapy, take into account the indications and contraindications for their use, as well as the cost of drugs.
4. Start therapy using minimal doses of drugs to avoid side effects.
Basic antihypertensive drugs
Of the six groups of antihypertensive drugs currently used, the most proven effectiveness is thiazide diuretics and β-blockers. Drug therapy should be started with low doses of thiazide diuretics, and in the absence of effectiveness or poor tolerability, with β-blockers.
Diuretics
Thiazide diuretics are recommended as first-line drugs for the treatment of hypertension. To avoid side effects, low doses of thiazide diuretics should be prescribed. The optimal dose of thiazide and thiazide-like diuretics is the minimum effective dose, corresponding to 12.5-25 mg of hydrochloride. Diuretics in very low doses (6.25 mg hydrochloride or 0.625 mg indapamide) increase the effectiveness of other antihypertensive agents without undesirable metabolic changes.
Hydrochlorbiazide orally at a dose of 12.5-25 mg in the morning for a long time. Indapamide orally 2.5 mg (long-acting form 1.5 mg) once in the morning for a long time.

The word “hypertension” means that the human body had to increase blood pressure for some purpose. Depending on the conditions that can cause this condition, there are types of hypertension, and each of them is treated in its own way.
Classification of arterial hypertension, taking into account only the cause of the disease:
- Its cause cannot be identified by examining those organs whose disease requires the body to increase blood pressure. It is because of an unclear reason that it is called essential or idiopathic(both terms translate as "unclear cause"). Domestic medicine calls this type of chronic increase in blood pressure hypertension. Due to the fact that this disease will have to be reckoned with all your life (even after the pressure returns to normal, you will need to follow certain rules so that it does not increase again), in popular circles it is called chronic hypertension, and it is this that is divided into the degrees, stages and risks discussed below.
- - one for which the cause can be identified. It has its own classification - according to the factor that “triggered” the mechanism of increasing blood pressure. We'll talk about this below.
Both primary and secondary hypertension are divided according to the type of increase in blood pressure. So, hypertension can be:
There is also a classification based on the nature of the disease. It divides both primary and secondary hypertension into:
According to another definition, malignant hypertension is an increase in blood pressure to 220/130 mmHg. Art. and more, when the ophthalmologist detects grade 3-4 retinopathy in the fundus (hemorrhages, retinal edema or optic nerve edema and vasoconstriction, and a kidney biopsy diagnoses “fibrinoid arteriolonecrosis.”
Symptoms of malignant hypertension are headaches, spots before the eyes, pain in the heart, and dizziness.
Before this we wrote “upper”, “lower”, “systolic”, “diastolic” pressure, what does this mean?
Systolic (or “upper”) pressure is the force with which blood presses on the walls of large arterial vessels (that’s where it is thrown out) during compression of the heart (systole). Essentially, these arteries, with a diameter of 10-20 mm and a length of 300 mm or more, must “squeeze” the blood that is thrown into them.
Only systolic pressure increases in two cases:
- when the heart pumps out a large amount of blood, which is typical for hyperthyroidism, a condition in which the thyroid gland produces an increased amount of hormones that cause the heart to contract strongly and frequently;
- when the elasticity of the aorta is reduced, which is observed in older people.
Diastolic (“lower”) is the pressure of fluid on the walls of large arterial vessels that occurs during relaxation of the heart - diastole. In this phase of the cardiac cycle, the following occurs: large arteries must transfer the blood entering them during systole to arteries and arterioles of smaller diameter. After this, the aorta and large arteries need to prevent overload of the heart: while the heart relaxes, accepting blood from the veins, the large vessels must have time to relax in anticipation of its contraction.
The level of arterial diastolic pressure depends on:
- The tone of such arterial vessels (according to Tkachenko B.I. “ Normal human physiology." - M, 2005), which are called vessels of resistance:
- mainly those that have a diameter of less than 100 micrometers, arterioles are the last vessels before the capillaries (these are the smallest vessels from where substances penetrate directly into the tissues). They have a muscular layer of circular muscles, which are located between various capillaries and are a kind of “faucets”. Switching these “faucets” determines which part of the organ will now receive more blood (that is, nutrition), and which will receive less;
- to a small extent, the tone of the medium and small arteries (“distribution vessels”), which carry blood to the organs and are located inside the tissues, plays a role;
- Heart contraction rates: if the heart contracts too often, the vessels do not yet have time to deliver one portion of blood before the next one arrives;
- The amount of blood that is included in the blood circulation;
- Blood viscosity.
Isolated diastolic hypertension is very rare, mainly in diseases of the resistance vessels.
Most often, both systolic and diastolic pressure increase. This happens as follows:
When the heart begins to work against increased pressure, pushing blood into vessels with a thickened muscle wall, its muscle layer also increases (this is a common property for all muscles). This is called hypertrophy, and affects mainly the left ventricle of the heart, because it communicates with the aorta. There is no concept of “left ventricular hypertension” in medicine.
Primary arterial hypertension
The official widespread version says that the causes of primary hypertension cannot be found out. But physicist V.A. Fedorov and a group of doctors explained the increase in pressure by the following factors:
Carefully studying the mechanisms of the body, V.A. Fedorov with the doctors we saw that the vessels cannot nourish every cell of the body - after all, not all cells are close to the capillaries. They realized that cell nutrition is possible thanks to microvibration - a wave-like contraction of muscle cells, which make up more than 60% of body weight. These, described by academician Arinchin N.I., ensure the movement of substances and the cells themselves in the aqueous environment of the intercellular fluid, making it possible to provide nutrition, remove waste substances during the life process, and carry out immune reactions. When microvibration in one or several areas becomes insufficient, a disease occurs.
In their work, muscle cells that create microvibration use electrolytes present in the body (substances that can conduct electrical impulses: sodium, calcium, potassium, some proteins and organic substances). The balance of these electrolytes is maintained by the kidneys, and when the kidneys become diseased or the volume of working tissue in them decreases with age, microvibration begins to be lacking. The body tries as best it can to eliminate this problem by increasing blood pressure so that more blood flows to the kidneys, but because of this the whole body suffers.
Microvibration deficiency can lead to the accumulation of damaged cells and decay products in the kidneys. If they are not removed from there for a long time, they are transferred to the connective tissue, that is, the number of working cells decreases. Accordingly, the performance of the kidneys decreases, although their structure does not suffer.
The kidneys themselves do not have their own muscle fibers and receive microvibration from neighboring working muscles of the back and abdomen. Therefore, physical activity is necessary primarily to maintain the tone of the muscles of the back and abdomen, which is why correct posture is necessary even in a sitting position. According to V.A. Fedorov, “constant tension of the back muscles with correct posture significantly increases the saturation of internal organs with microvibration: kidneys, liver, spleen, improving their functioning and increasing the body’s resources. This is a very important circumstance that increases the importance of posture.” (" - Vasiliev A.E., Kovelenov A.Yu., Kovlen D.V., Ryabchuk F.N., Fedorov V.A., 2004)
A way out of the situation may be to provide additional microvibration (optimally in combination with thermal effects) to the kidneys: their nutrition is normalized, and they return the electrolyte balance of the blood to the “original settings.” Hypertension is thus resolved. At its initial stage, such treatment is enough to naturally lower blood pressure, without taking additional medications. If a person’s disease has “progressed far” (for example, it is grade 2-3 and the risk is 3-4), then the person may not be able to cope without taking medications prescribed by a doctor. At the same time, the message of additional microvibration will help reduce the doses of medications taken, and therefore reduce their side effects.

Types of secondary arterial hypertension
Secondary arterial hypertension occurs:
- (arising from a disease of the nervous system). It is divided into:
- centrogenic – it occurs due to disturbances in the functioning or structure of the brain;
- reflexogenic (reflex): in a certain situation or with constant irritation of the organs of the peripheral nervous system.
- (endocrine).
- – occurring when organs such as the spinal cord or brain suffer from a lack of oxygen.
- , it also has its division into:
- renovascular, when the arteries that bring blood to the kidneys narrow;
- renoparenchymatous, associated with damage to kidney tissue, which is why the body needs to increase blood pressure.
- (caused by blood diseases).
- (due to a change in the “route” of blood movement).
- (when it was caused by several reasons).
Let's tell you a little more.
The main command to large vessels, causing them to contract, increasing blood pressure, or relax, decreasing it, comes from the vasomotor center, which is located in the brain. If its work is disrupted, centrogenic hypertension develops. This can happen due to:
- Neuroses, that is, diseases when the structure of the brain does not suffer, but under the influence of stress a focus of excitation is formed in the brain. It involves the main structures that “include” an increase in pressure;
- Brain damage: injuries (concussions, bruises), brain tumors, stroke, inflammation of the brain (encephalitis). To increase blood pressure you must:
- or structures that directly affect blood pressure are damaged (the vasomotor center in the medulla oblongata or the associated hypothalamic nuclei or reticular formation);
- or extensive brain damage may occur with increased intracranial pressure, when in order to ensure blood supply to this vital organ the body will need to increase blood pressure.
Reflex hypertension is also classified as neurogenic. They can be:
- conditioned reflex, when at first there is a combination of some event with taking a medicine or drink that increases blood pressure (for example, if a person drinks strong coffee before an important meeting). After many repetitions, the pressure begins to rise only at the very thought of a meeting, without drinking coffee;
- unconditioned reflex, when the pressure increases after the cessation of long-term constant impulses from inflamed or pinched nerves to the brain (for example, if a tumor that was pressing on the sciatic or any other nerve was removed).
Endocrine (hormonal) hypertension
These are secondary hypertension, the causes of which are diseases of the endocrine system. They are divided into several types.
Adrenal hypertension
These glands, located above the kidneys, produce a large number of hormones that can affect vascular tone and the strength or frequency of heart contractions. Increased blood pressure can be caused by:
- Excessive production of adrenaline and norepinephrine, which is typical for a tumor such as pheochromocytoma. Both of these hormones simultaneously increase the strength and frequency of heart contractions and increase vascular tone;
- A large amount of the hormone aldosterone, which does not release sodium from the body. This element, appearing in the blood in large quantities, “attracts” water from the tissues. Accordingly, the amount of blood increases. This happens with a tumor that produces it - malignant or benign, with non-tumor growth of the tissue that produces aldosterone, as well as with stimulation of the adrenal glands in severe diseases of the heart, kidneys, and liver.
- Increased production of glucocorticoids (cortisone, cortisol, corticosterone), which increase the number of receptors (that is, special molecules on the cell that act as a “lock” that can be opened with a “key”) for adrenaline and norepinephrine (they will be the necessary “key” for “ castle") in the heart and blood vessels. They also stimulate the liver to produce the hormone angiotensinogen, which plays a key role in the development of hypertension. An increase in the amount of glucocorticoids is called Cushing's syndrome and disease (a disease when the pituitary gland commands the adrenal glands to produce a large amount of hormones, a syndrome when the adrenal glands are affected).
Hyperthyroid hypertension
It is associated with excessive production of the thyroid hormones – thyroxine and triiodothyronine. This leads to an increase in heart rate and the amount of blood ejected by the heart per beat.
The production of thyroid hormones can increase with autoimmune diseases such as Graves' disease and Hashimoto's thyroiditis, with inflammation of the gland (subacute thyroiditis), and some of its tumors.
Excessive release of antidiuretic hormone by the hypothalamus
This hormone is produced in the hypothalamus. Its second name is vasopressin (translated from Latin as “squeezing blood vessels”), and it acts in this way: by binding to receptors on the vessels inside the kidney, it causes them to narrow, resulting in less urine being produced. Accordingly, the volume of liquid in the vessels increases. More blood flows to the heart - it stretches more. This leads to increased blood pressure.
Hypertension can also be caused by an increase in the body's production of active substances that increase vascular tone (these are angiotensins, serotonin, endothelin, cyclic adenosine monophosphate) or a decrease in the amount of active substances that should dilate blood vessels (adenosine, gamma-aminobutyric acid, nitric oxide, some prostaglandins).
The decline of the function of the gonads is often accompanied by a constant increase in blood pressure. The age at which each woman enters menopause is different (it depends on genetic characteristics, living conditions and the state of the body), but German doctors have proven that the age over 38 years is dangerous for the development of arterial hypertension. It is after 38 years that the number of follicles (from which eggs are formed) begins to decrease not by 1-2 every month, but by dozens. A decrease in the number of follicles leads to a decrease in the production of hormones by the ovaries, as a result of which vegetative (sweating, paroxysmal feeling of heat in the upper body) and vascular (redness of the upper half of the body during a hot attack, increased blood pressure) disorders develop.
Hypoxic hypertension
They develop when blood supply to the medulla oblongata, where the vasomotor center is located, is disrupted. This is possible with atherosclerosis or thrombosis of the vessels carrying blood to it, as well as with compression of the vessels due to edema and hernias.
Renal hypertension
As already mentioned, there are 2 types of them:
Vasorenal (or renovascular) hypertension
It is caused by deterioration of the blood supply to the kidneys due to narrowing of the arteries supplying the kidneys. They suffer from the formation of atherosclerotic plaques in them, an increase in the muscle layer in them due to a hereditary disease - fibromuscular dysplasia, aneurysm or thrombosis of these arteries, aneurysm of the renal veins.
The disease is based on activation of the hormonal system, which causes blood vessels to spasm (contract), sodium retention occurs, and fluid in the blood increases, and the sympathetic nervous system is stimulated. The sympathetic nervous system, through its special cells located on the vessels, activates their even greater compression, which leads to an increase in blood pressure.
Renoparenchymal hypertension
It accounts for only 2-5% of hypertension cases. It occurs due to diseases such as:
- glomerulonephritis;
- kidney damage due to diabetes;
- one or more cysts in the kidneys;
- kidney injury;
- kidney tuberculosis;
- kidney tumor.
With any of these diseases, the number of nephrons (the main working units of the kidneys through which blood is filtered) decreases. The body tries to correct the situation by increasing the pressure in the arteries that carry blood to the kidneys (the kidneys are an organ for which blood pressure is very important; if the pressure is low, they stop working).
Drug-induced hypertension
The following drugs can cause increased blood pressure:
- vasoconstrictor drops used for a runny nose;
- tablet contraceptives;
- antidepressants;
- painkillers;
- drugs based on glucocorticoid hormones.
Hemic hypertension
Due to an increase in blood viscosity (for example, in Vaquez disease, when the number of all its cells in the blood increases) or an increase in blood volume, blood pressure may increase.
Hemodynamic hypertension
This is the name for hypertension, which is based on changes in hemodynamics - that is, the movement of blood through the vessels, usually as a result of diseases of large vessels.
The main disease causing hemodynamic hypertension is coarctation of the aorta. This is a congenital narrowing of the aorta in its thoracic (located in the chest cavity) section. As a result, in order to ensure normal blood supply to the vital organs of the thoracic cavity and cranial cavity, blood must reach them through rather narrow vessels that are not designed for such a load. If the blood flow is large and the diameter of the vessels is small, the pressure in them will increase, which is what happens with coarctation of the aorta in the upper half of the body.
The body needs the lower extremities less than the organs of the indicated cavities, so the blood reaches them “not under pressure.” Therefore, such a person’s legs are pale, cold, thin (the muscles are poorly developed due to insufficient nutrition), and the upper half of the body has an “athletic” appearance.
Alcoholic hypertension
How ethyl alcohol-based drinks cause increased blood pressure is still unclear to scientists, but 5-25% of people who regularly drink alcohol have increased blood pressure. There are theories suggesting that ethanol may affect:
- through increased activity of the sympathetic nervous system, which is responsible for vasoconstriction and increased heart rate;
- by increasing the production of glucocorticoid hormones;
- due to the fact that muscle cells more actively absorb calcium from the blood, and are therefore in a state of constant tension.
Mixed hypertension
When any provoking factors are combined (for example, kidney disease and taking painkillers), they add up (summation).
Certain types of hypertension that are not included in the classification
There is no official concept of “juvenile hypertension”. Increased blood pressure in children and adolescents is mainly of a secondary nature. The most common causes of this condition are:
- Congenital malformations of the kidneys.
- Congenital narrowing of the diameter of the renal arteries.
- Pyelonephritis.
- Glomerulonephritis.
- Cyst or polycystic kidney disease.
- Kidney tuberculosis.
- Kidney injury.
- Coarctation of the aorta.
- Essential hypertension.
- Wilms tumor (nephroblastoma) is an extremely malignant tumor that develops from kidney tissue.
- Lesions of either the pituitary gland or the adrenal glands, resulting in a lot of glucocorticoid hormones in the body (Itsenko-Cushing syndrome and disease).
- Thrombosis of arteries or veins of the kidneys
- Narrowing of the diameter (stenosis) of the renal arteries due to a congenital increase in the thickness of the muscular layer of the vessels.
- Congenital disorder of the adrenal cortex, the hypertensive form of this disease.
- Bronchopulmonary dysplasia is damage to the bronchi and lungs by air blown into the ventilator, which was connected to resuscitate the newborn.
- Pheochromocytoma.
- Takayasu's disease is a lesion of the aorta and large branches extending from it due to an attack on the walls of these vessels by one's own immunity.
- Periarteritis nodosa is an inflammation of the walls of small and medium-sized arteries, resulting in the formation of saccular protrusions - aneurysms.
Pulmonary hypertension is not a type of arterial hypertension. This is a life-threatening condition in which the pressure in the pulmonary artery increases. This is the name of the 2 vessels into which the pulmonary trunk (the vessel emanating from the right ventricle of the heart) is divided. The right pulmonary artery carries oxygen-poor blood to the right lung, the left - to the left.
Pulmonary hypertension develops most often in women 30-40 years old and, gradually progressing, is a life-threatening condition, leading to disruption of the right ventricle and premature death. It occurs due to hereditary causes, connective tissue diseases, and heart defects. In some cases, its cause cannot be determined. Manifested by shortness of breath, fainting, fatigue, dry cough. In severe stages, the heart rhythm is disturbed and hemoptysis appears.
Stages, degrees and risk factors
In order to select treatment for people suffering from hypertension, doctors came up with a classification of hypertension according to stages and degrees. We will present it in the form of tables.
Stages of hypertension
The stages of hypertension indicate how much the internal organs have suffered from constantly increased pressure:
Damage to target organs, which include the heart, blood vessels, kidneys, brain, retina |
|
---|---|
The heart, blood vessels, kidneys, eyes, brain are not yet affected |
|
|
|
One of the complications of hypertension has developed:
|
Blood pressure figures at any stage are above 140/90 mmHg. Art.
Treatment of the initial stage of hypertension is mainly aimed at changing lifestyle: including mandatory in the daily routine. Whereas stage 2 and 3 hypertension should already be treated using. Their dose and, accordingly, side effects can be reduced if you help the body restore blood pressure naturally, for example, by giving it additional help.
Degrees of hypertension
The degrees of development of hypertension indicate how high the blood pressure is:
The degree is established without taking blood pressure-lowering drugs. To do this, a person who is forced to take medications that lower blood pressure needs to reduce their dose or completely stop it.
The degree of hypertension is judged by the number of the pressure (“upper” or “lower”), which is greater.
Sometimes grade 4 hypertension is classified. It is treated as isolated systolic hypertension. In any case, we mean a condition when only the upper pressure is increased (above 140 mm Hg), while the lower pressure is within normal limits - up to 90 mm Hg. This condition is most often recorded in older people (associated with decreased elasticity of the aorta). Occurring in young people, isolated systolic hypertension indicates that the thyroid gland needs to be examined: this is how hyperthyroidism “behaves” (an increase in the amount of thyroid hormones produced).
Definition of risk
There is also a classification according to risk groups. The higher the number indicated after the word “risk,” the higher the likelihood that a dangerous disease will develop in the coming years.
There are 4 risk levels:
- At risk 1 (low), the probability of developing a stroke or heart attack in the next 10 years is less than 15%;
- With risk 2 (average), this probability in the next 10 years is 15-20%;
- At risk 3 (high) – 20-30%;
- At risk 4 (very high) – more than 30%.
Risk factor |
Criterion |
---|---|
Arterial hypertension |
Systolic pressure >140 mm Hg. and/or diastolic pressure > 90 mm Hg. Art. |
More than 1 cigarette per week |
|
Impaired fat metabolism (according to Lipidogram analysis) |
|
Increased fasting glucose (based on blood sugar test) |
Fasting plasma glucose 5.6-6.9 mmol/l or 100-125 mg/dl Glucose 2 hours after taking 75 grams of glucose – less than 7.8 mmol/L or less than 140 mg/dL |
Low glucose tolerance (digestibility) |
Fasting plasma glucose less than 7 mmol/L or 126 mg/dL 2 hours after taking 75 grams, glucose is more than 7.8 but less than 11.1 mmol/l (≥140 and<200 мг/дл) |
Cardiovascular diseases in close relatives |
They are taken into account in men under 55 years of age and women under 65 years of age |
Obesity (it is assessed by the Quetelet index, I I=body weight/height in meters* height in meters. Norm I = 18.5-24.99; Pre-obesity I = 25-30) |
Obesity of the first degree, where the Quetelet index is 30-35; II degree 35-40; III degree 40 or more. |
To assess the risk, target organ damage is also assessed, which is either present or absent. Target organ damage is assessed by:
- hypertrophy (enlargement) of the left ventricle. It is assessed by electrocardiogram (ECG) and cardiac ultrasound;
- kidney damage: for this, the presence of protein is assessed in a general urine test (normally it should not be present), as well as blood creatinine (normally it should be less than 110 µmol/l).
The third criterion that is assessed to determine the risk factor is concomitant diseases:
- Diabetes mellitus: it is diagnosed if fasting plasma glucose is more than 7 mmol/l (126 mg/dl), and 2 hours after taking 75 g of glucose - more than 11.1 mmol/l (200 mg/dl);
- Metabolic syndrome. This diagnosis is established if there are at least 3 criteria from the following, and body weight is necessarily considered one of them:
- HDL cholesterol less than 1.03 mmol/l (or less than 40 mg/dl);
- systolic blood pressure more than 130 mm Hg. Art. and/or diastolic pressure greater than or equal to 85 mm Hg. Art.;
- glucose more than 5.6 mmol/l (100 mg/dl);
- waist circumference in men is more than or equal to 94 cm, in women – more than or equal to 80 cm.
Setting the risk level:
Risk level |
Diagnosis criteria |
---|---|
These are men and women under 55 years of age who, apart from high blood pressure, have no other risk factors, no target organ damage, or concomitant diseases |
|
Men over 55 years old, women over 65 years old. There are 1-2 risk factors (including arterial hypertension). No target organ damage |
|
3 or more risk factors, target organ damage (left ventricular hypertrophy, kidney or retinal damage), or diabetes mellitus, or ultrasound detected atherosclerotic plaques in any arteries |
|
Have diabetes, angina or metabolic syndrome. It was one of the following:
|
There is no direct connection between the degree of pressure increase and the risk group, but at a high stage the risk will be high. For example, there may be hypertension Stage 1, degree 2, risk 3(that is, there is no damage to target organs, pressure is 160-179/100-109 mm Hg, but the probability of heart attack/stroke is 20-30%), and this risk can be either 1 or 2. But if stage 2 or 3, then the risk cannot be lower than 2.
Examples and interpretation of diagnoses - what do they mean?
What it is - hypertension stage 2, degree 2, risk 3?:
- blood pressure 160-179/100-109 mmHg. Art.
- there are heart problems, determined by ultrasound of the heart, or there is a disorder of the kidneys (according to tests), or there is a disorder in the fundus, but there is no visual impairment;
- there may be either diabetes mellitus, or atherosclerotic plaques are found in some vessel;
- in 20-30% of cases, either a stroke or a heart attack will develop in the next 10 years.
Stage 3, degree 2, risk 3? Here, in addition to the parameters indicated above, there are also complications of hypertension: angina pectoris, myocardial infarction, chronic heart or renal failure, damage to retinal vessels.
Hypertonic disease 3 degrees 3 stages risk 3- everything is the same as for the previous case, only the blood pressure numbers are more than 180/110 mm Hg. Art.
What is hypertension Stage 2, degree 2, risk 4? Blood pressure 160-179/100-109 mmHg. Art., target organs are affected, there is diabetes mellitus or metabolic syndrome.
It even happens when 1st degree hypertension, when the pressure is 140-159/85-99 mm Hg. Art., already available Stage 3, that is, life-threatening complications developed (angina pectoris, myocardial infarction, heart or kidney failure), which, together with diabetes mellitus or metabolic syndrome, caused risk 4.
This does not depend on how much the blood pressure increases (the degree of hypertension), but on what complications the persistently high blood pressure caused:
Stage 1 hypertension
In this case, there is no damage to target organs, so disability is not given. But the cardiologist gives recommendations to the person, which he must take to the workplace, where it is written that he has certain restrictions:
- Heavy physical and emotional stress is contraindicated;
- You cannot work the night shift;
- work in conditions of intense noise and vibration is prohibited;
- You cannot work at height, especially when a person is servicing electrical networks or electrical units;
- You cannot perform those types of work in which a sudden loss of consciousness can create an emergency situation (for example, public transport drivers, crane operators);
- those types of work in which there is a change in temperature conditions are prohibited (bathhouse attendants, physiotherapists).
Stage 2 hypertension
In this case, target organ damage is implied, which worsens the quality of life. Therefore, at the VTEK (MSEC) - medical labor or health expert commission - he is given disability group III. At the same time, the restrictions that are indicated for stage 1 of hypertension remain the same. A working day for such a person can be no more than 7 hours.
To obtain disability you need:
- submit an application addressed to the chief physician of the medical institution where MSEC is carried out;
- receive a referral to a commission at the clinic at your place of residence;
- confirm the group annually.
Stage 3 hypertension
Diagnosis of hypertension 3 stages, no matter how high the pressure is - 2 degrees or more, implies damage to the brain, heart, eyes, kidneys (especially if there is a combination with diabetes mellitus or metabolic syndrome, which gives it risk 4), which significantly limits the ability to work. Because of this, a person can receive II or even I group disability.
Let's consider the “relationship” between hypertension and the army, regulated by Decree of the Government of the Russian Federation of July 4, 2013 N 565 “On approval of the Regulations on military medical examination”, Article 43:
Are they recruited into the army with hypertension if the increase in blood pressure is associated with disorders of the autonomic (which controls the internal organs) nervous system: sweating of the hands, variability of pulse and pressure when changing body position)? In this case, a medical examination is carried out under Article 47, on the basis of which either category “B” or “B” is assigned (“B” - fit with minor restrictions).
If, in addition to hypertension, the conscript has other diseases, they will be examined separately.
Is it possible to completely cure hypertension? This is possible if you eliminate those described in detail above. To do this, you need to be thoroughly examined, if one doctor does not help you find the cause, consult with him about which specialist you should go to. Indeed, in some cases, it is possible to remove a tumor or expand the diameter of blood vessels with a stent - and get rid of painful attacks forever and reduce the risk of life-threatening diseases (heart attack, stroke).
Don't forget: a number of causes of hypertension can be eliminated by giving the body additional information. This is called, and helps speed up the removal of damaged and spent cells. In addition, it renews immune reactions and helps to carry out reactions at the tissue level (it will act like a massage at the cellular level, improving the connection of necessary substances with each other). As a result, the body will not need to increase blood pressure.
The phonation procedure can be performed while sitting comfortably on the bed. The devices do not take up much space, are easy to use, and their cost is quite affordable for the general population. Its use is more cost-effective: this way you make a one-time purchase, instead of constantly purchasing medications, and, in addition, the device can treat not only hypertension, but also other diseases, and can be used by all family members). It is also useful to use phonation after eliminating hypertension: the procedure will increase the tone and resources of the body. With help you can achieve general health improvement.
The effectiveness of the devices is confirmed.
For the treatment of stage 1 hypertension, such an effect may be quite sufficient, but when a complication has already developed, or hypertension is accompanied by diabetes mellitus or metabolic syndrome, therapy should be agreed upon with a cardiologist.

The material was prepared by Villevalde S.V., Kotovskaya Yu.V., Orlova Y.A.
The central event of the 28th European Congress on Arterial Hypertension and Cardiovascular Prevention was the first presentation of a new version of the joint recommendations for the management of arterial hypertension (HTN) of the European Society of Cardiology and the European Society of Hypertension. The text of the document will be published on August 25, 2018, simultaneously with the official presentation at the Congress of the European Society of Cardiology, which will take place on August 25-29, 2018 in Munich. The publication of the full text of the document will undoubtedly give rise to analysis and detailed comparison with the recommendations of American societies, presented in November 2017, which radically changed the diagnostic criteria for hypertension and target blood pressure (BP) levels. The purpose of this material is to provide information on the key provisions of the updated European recommendations.
The full recording of the plenary meeting, where the recommendations were presented, can be viewed on the website of the European Society for AH www.eshonline.org/esh-annual-meeting.
Classification of blood pressure levels and determination of hypertension
Experts from the European Society of Hypertension have retained the classification of blood pressure levels and the definition of hypertension and recommend classifying blood pressure as optimal, normal, high normal and identifying grades 1, 2 and 3 of hypertension (class of recommendations I, level of evidence C) (Table 1).
Table 1. Classification of clinical blood pressure
The criterion for hypertension according to clinical blood pressure measurements remained a level of 140 mm Hg. and higher for systolic (SBP) and 90 mm Hg. and higher - for diastolic (DBP). For home blood pressure measurements, SBP 135 mmHg was retained as a criterion for hypertension. and above and/or DBP 85 mm Hg. and higher. According to daily blood pressure monitoring, the diagnostic cut-off points for average daily blood pressure were, respectively, 130 and 80 mm Hg, daytime - 135 and 85 mm Hg, night - 120 and 70 mm Hg (Table 2) .
Table 2. Diagnostic criteria for hypertension according to clinical and outpatient measurements
Blood pressure measurement
The diagnosis of hypertension continues to rely on clinical BP measurements, with the use of ambulatory BP measurements encouraged and the complementary value of ambulatory blood pressure monitoring (ABPM) and home BP measurements emphasized. For office-based, unattended BP measurement, it is recognized that there is currently insufficient evidence to recommend it for widespread clinical use.
Advantages of ABPM include: detection of white-coat hypertension, stronger prognostic value, assessment of BP levels at night, measurement of BP in the patient's real life, additional ability to identify prognostically significant BP phenotypes, broad information in a single test, including short-term BP variability. Limitations of ABPM include the high cost and limited availability of the study, as well as its possible inconvenience for the patient.
Advantages of home BP measurement include detection of white coat hypertension, cost-effectiveness and widespread availability, measurement of BP in routine settings when the patient is more relaxed than at the doctor's office, patient participation in BP measurement, ability to be repeated over long periods of time, and assessment of variability. "day by day". The disadvantage of the method is the possibility of obtaining measurements only at rest, the likelihood of erroneous measurements and the lack of measurements during sleep.
The following are recommended as indications for performing ambulatory blood pressure measurements (ABPM or home blood pressure): conditions when there is a high probability of white coat hypertension (stage 1 hypertension when clinically measured, a significant increase in clinical blood pressure without target organ damage associated with hypertension), conditions when latent hypertension is highly likely (high normal BP by clinical measurement, normal clinical BP in a patient with end-organ damage or high overall cardiovascular risk), postural and postprandial hypotension in patients not receiving and receiving antihypertensive therapy, assessment of resistant hypertension , assessment of blood pressure control, especially in high-risk patients, excessive blood pressure response to exercise, significant variability in clinical blood pressure, assessment of symptoms indicating hypotension during antihypertensive therapy. A specific indication for performing ABPM is the assessment of nocturnal BP and nocturnal decrease in BP (for example, if nocturnal hypertension is suspected in patients with sleep apnea, chronic kidney disease (CKD), diabetes mellitus (DM), endocrine hypertension, autonomic dysfunction).
Screening and diagnosis of hypertension
To diagnose hypertension, clinical blood pressure measurement is recommended as a first step. When hypertension is detected, it is recommended to either measure blood pressure at follow-up visits (except in cases of grade 3 blood pressure elevation, especially in high-risk patients), or perform ambulatory blood pressure measurement (ABPM or self-monitoring of blood pressure (SBP)). At each visit, 3 measurements should be taken with an interval of 1-2 minutes, an additional measurement should be performed if the difference between the first two measurements is more than 10 mmHg. The patient's blood pressure level is taken as the average of the last two measurements (IC). Ambulatory BP measurement is recommended in a number of clinical situations, such as identifying white-coat hypertension or latent hypertension, quantifying the effectiveness of treatment, and identifying adverse events (symtometic hypotension) (IA).
If white coat hypertension or occult hypertension is detected, lifestyle interventions to reduce cardiovascular risk are recommended, as well as regular monitoring using ambulatory BP measurement (IC). In patients with white coat hypertension, drug treatment of hypertension may be considered in the presence of hypertension-related target organ damage or high/very high cardiovascular risk (IIbC), but routine use of BP-lowering medications is not indicated (IIIC) .
In patients with latent hypertension, drug antihypertensive therapy should be considered to normalize ambulatory blood pressure (IIaC), and in patients receiving treatment with uncontrolled ambulatory blood pressure, intensification of antihypertensive therapy due to the high risk of cardiovascular complications (IIaC).
Regarding blood pressure measurement, the question of the optimal method for measuring blood pressure in patients with atrial fibrillation remains unresolved.
Figure 1. Algorithm for screening and diagnosis of hypertension.
Classification of hypertension and stratification by risk of developing cardiovascular complications
The Recommendations retain the approach to determining the overall cardiovascular risk using SCORE, taking into account the fact that in patients with hypertension, this risk increases significantly in the presence of target organ damage associated with hypertension (especially left ventricular hypertrophy, CKD). Among the factors influencing the cardiovascular prognosis in patients with hypertension, the level of uric acid was added (more precisely, returned), early menopause, psychosocial and economic factors, and a resting heart rate of 80 beats/min or more were added. Asymptomatic target organ damage associated with hypertension includes moderate CKD with glomerular filtration rate (GFR)<60 мл/мин/1,73м 2 , и тяжелая ХБП с СКФ <30 мл/мин/1,73 м 2 (расчет по формуле CKD-EPI), а также выраженная ретинопатия с геморрагиями или экссудатами, отеком соска зрительного нерва. Бессимптомное поражение почек также определяется по наличию микроальбуминурии или повышенному отношению альбумин/креатинин в моче.
The list of established diseases of the cardiovascular system is supplemented by the presence of atherosclerotic plaques in imaging studies and atrial fibrillation.
An approach has been introduced to classify hypertension according to the stages of the disease (hypertension), taking into account the level of blood pressure, the presence of risk factors affecting the prognosis, target organ damage associated with hypertension, and comorbid conditions (Table 3).
The classification covers the range of blood pressure from high normal to grade 3 hypertension.
There are 3 stages of hypertension (hypertension). The stage of hypertension does not depend on the level of blood pressure, but is determined by the presence and severity of target organ damage.
Stage 1 (uncomplicated) - there may be other risk factors, but there is no end-organ damage. At this stage, patients with grade 3 hypertension are classified as high risk, regardless of the number of risk factors, as well as patients with grade 2 hypertension with 3 or more risk factors. The moderate-high risk category includes patients with stage 2 hypertension and 1-2 risk factors, as well as stage 1 hypertension with 3 or more risk factors. The moderate risk category includes patients with grade 1 hypertension and 1-2 risk factors, grade 2 hypertension without risk factors. Patients with high normal blood pressure and 3 or more risk factors correspond to low-moderate risk. The remaining patients were classified as low risk.
Stage 2 (asymptomatic) implies the presence of asymptomatic target organ damage associated with hypertension; CKD stage 3; DM without target organ damage and assumes the absence of symptomatic cardiovascular diseases. The state of target organs corresponding to stage 2, with high normal blood pressure, places the patient in the moderate-high risk group, with increased blood pressure of 1-2 degrees - in the high-risk category, 3 degrees - in the high-very high risk category.
Stage 3 (complicated) is determined by the presence of symptomatic cardiovascular diseases, CKD stage 4 or higher, and diabetes with target organ damage. This stage, regardless of blood pressure level, places the patient in the very high risk category.
Assessment of organ damage is recommended not only to determine risk, but also for monitoring during treatment. Changes in electro- and echocardiographic signs of left ventricular hypertrophy and GFR during treatment have a high prognostic value; moderate - dynamics of albuminuria and ankle-brachial index. Changes in the thickness of the intima-medial layer of the carotid arteries have no prognostic significance. There is insufficient data to conclude on the prognostic value of pulse wave velocity dynamics. There is no data on the significance of the dynamics of signs of left ventricular hypertrophy according to magnetic resonance imaging.
The role of statins has been emphasized to reduce cardiovascular risk, including greater risk reduction while achieving BP control. Antiplatelet therapy is indicated for secondary prevention and is not recommended for primary prevention in patients without cardiovascular disease.

Initiation of antihypertensive therapy
Lifestyle changes are recommended for all patients with hypertension or high normal blood pressure. The time of initiation of drug therapy (simultaneously with non-drug interventions or delayed) is determined by the level of clinical blood pressure, the level of cardiovascular risk, the presence of target organ damage or cardiovascular diseases (Fig. 2). As before, immediate initiation of drug antihypertensive therapy is recommended for all patients with grade 2 and 3 hypertension, regardless of the level of cardiovascular risk (IA), and the target blood pressure level should be achieved no later than after 3 months.
In patients with stage 1 hypertension, recommendations for lifestyle changes should begin with subsequent assessment of their effectiveness in normalizing blood pressure (IIB). In patients with grade 1 hypertension at high/very high cardiovascular risk, with cardiovascular disease, renal disease, or evidence of end-organ damage, drug antihypertensive therapy is recommended concomitantly with the initiation of lifestyle interventions (IA). A more decisive (IA) approach compared to the 2013 Guidelines (IIaB) is the approach to initiating drug antihypertensive therapy in patients with stage 1 hypertension with low-moderate cardiovascular risk without heart or kidney disease, without signs of target organ damage in the absence of normalization BP after 3-6 months of initial lifestyle change strategy.
A new provision of the 2018 Recommendations is the possibility of drug therapy in patients with high normal blood pressure (130-139/85-89 mm Hg) in the presence of a very high cardiovascular risk due to the presence of cardiovascular diseases, especially coronary heart disease (CHD). ) (IIbA). According to the 2013 Guidelines, drug antihypertensive therapy was not indicated in patients with high normal blood pressure (IIIA).
One of the new conceptual approaches in the 2018 version of the European recommendations is a less conservative tactic for blood pressure control in the elderly. Experts suggest lower cut-off blood pressure levels for initiating antihypertensive therapy and lower target blood pressure levels in elderly patients, emphasizing the importance of assessing the patient's biological rather than chronological age, taking into account frailty, ability to self-care, and tolerability of therapy.
In fit older patients (even those aged >80 years), antihypertensive therapy and lifestyle changes are recommended when SBP is ≥160 mmHg. (IA). The grade of recommendation and level of evidence was increased (to IA versus IIbC in 2013) for antihypertensive drug therapy and lifestyle changes in “robust” elderly patients (> 65 years, but not older than 80 years) with SBP levels in the range of 140-159 mm Hg, provided the treatment is well tolerated. If therapy is well tolerated, drug therapy may also be considered in frail elderly patients (IIbB).
It should be borne in mind that the patient’s achievement of a certain age (even 80 years or more) is not a reason for not prescribing or discontinuing antihypertensive therapy (IIIA), provided it is well tolerated.

Notes: CVD – cardiovascular diseases, IHD – coronary heart disease, AH-POM – target organ damage associated with AH
Target blood pressure levels
Presenting their attitude to the results of the SPRINT study, which were taken into account in the United States when formulating new criteria for the diagnosis of hypertension and target blood pressure levels, European experts point out that office measurement of blood pressure without the presence of medical personnel has not previously been used in any of the randomized clinical trials, which served as an evidence base for making decisions on the treatment of hypertension. When measuring blood pressure without the presence of medical personnel, there is no white coat effect, and compared with conventional measurement, the SBP level may be lower by 5-15 mmHg. It is hypothesized that SBP levels in the SPRINT study may correspond to routinely measured SBP levels of 130–140 and 140–150 mmHg. in groups of more and less intensive antihypertensive therapy.
Experts acknowledge that there is strong evidence of benefit from lowering SBP below 140 and even 130 mmHg. Data from a large meta-analysis of randomized clinical trials are presented (Ettehad D, et al. Lancet. 2016;387(10022):957-967), which showed a significant reduction in the risk of developing major hypertension-associated cardiovascular complications with a decrease in SBP for every 10 mm Hg at the initial level 130-139 mmHg. (that is, when the SBP level is less than 130 mm Hg during treatment): the risk of coronary heart disease by 12%, stroke - by 27%, heart failure - by 25%, major cardiovascular events - by 13%, death from any reasons – by 11%. Additionally, another meta-analysis of randomized trials (Thomopoulos C, et al, J Hypertens. 2016;34(4):613-22) also demonstrated a reduction in the risk of major cardiovascular outcomes when achieving SBP less than 130 or DBP less 80 mmHg compared with a less intense decrease in blood pressure (mean blood pressure levels were 122.1/72.5 and 135.0/75.6 mmHg).
However, European experts also provide arguments in support of a conservative approach to target blood pressure levels:
- the incremental benefit of lowering blood pressure decreases as target blood pressure levels decrease;
- Achieving lower BP levels while on antihypertensive therapy is associated with a higher incidence of serious adverse events and discontinuation of therapy;
- Currently, less than 50% of patients receiving antihypertensive therapy achieve target SBP levels<140 мм рт.ст.;
- The evidence for the benefit of lower BP targets is less convincing in several important subpopulations of patients with hypertension: the elderly, those with diabetes, CKD, and CAD.
However, the same blood pressure level cannot be applied to all patients with hypertension. Differences in target SBP levels are determined by patient age and comorbid conditions. Lower SBP targets of 130 mmHg are proposed. or lower - for patients with diabetes (subject to careful monitoring of adverse events) and coronary artery disease (Table 4). In patients with a history of stroke, consider a target SBP of 120 (<130) мм рт.ст. Пациентам с АГ 65 лет и старше или имеющим ХБП рекомендуется достижение целевого уровня САД 130 (<140) мм рт.ст.

A summary of the 2018 Recommendations for target ranges for office BP is presented in Table 5. A new provision that is important for real clinical practice is the designation of the level below which BP should not be reduced: for all patients it is 120 and 70 mm Hg.

Notes: DM – diabetes mellitus, IHD – coronary heart disease, CKD – chronic kidney disease, TIA – transient ischemic attack.
When discussing ambulatory BP targets (ABPM or ABPM), it should be kept in mind that no randomized clinical trials with hard endpoints have used ABPM or ABPM as criteria for changing antihypertensive therapy. Data on target levels of ambulatory blood pressure are obtained only from extrapolation from observational studies. In addition, the differences between office and ambulatory BP levels decrease as office BP levels decrease. Thus, convergence of 24-hour and office blood pressure is observed at a level of 115-120/70 mmHg. We can assume that the target level of office SBP is 130 mm Hg. approximately corresponds to a 24-hour SBP level of 125 mm Hg. with ABPM and SBP level<130 мм рт.ст. при СКАД.
Along with the optimal target levels of ambulatory blood pressure (ABPM and SBP), questions remain open about the target blood pressure levels in young patients with hypertension and low cardiovascular risk, the target level of DBP.
Lifestyle changes
Treatment of hypertension includes lifestyle changes and drug therapy. Many patients will require drug therapy, but lifestyle changes are important. They can prevent or delay the development of hypertension and reduce cardiovascular risk, delay or eliminate the need for drug therapy in patients with stage 1 hypertension, and enhance the effects of antihypertensive therapy. However, lifestyle changes should never be a reason to delay drug therapy in patients at high cardiovascular risk. The main disadvantage of non-pharmacological interventions is low patient compliance and its decline over time.
Recommended lifestyle changes with a proven lowering effect on blood pressure include: limiting salt, no more than moderate alcohol consumption, high consumption of vegetables and fruits, losing and maintaining body weight, and regular exercise. In addition, a strong recommendation to quit smoking is mandatory. Tobacco smoking has an acute pressor effect that may increase ambulatory daytime blood pressure. Smoking cessation, in addition to its effect on blood pressure, is also important for reducing cardiovascular risk and preventing cancer.
In the previous version of the guidelines, the levels of evidence for lifestyle interventions were stratified by effects on BP and other cardiovascular risk factors and on hard endpoints (cardiovascular outcomes). In the 2018 Guidelines, experts indicated a combined level of evidence. The following lifestyle changes are recommended for patients with hypertension:
- Limit salt intake to 5 g per day (IA). A more stringent position compared to the 2013 version, where a limit to 5-6 g per day was recommended;
- Limit alcohol consumption to 14 units per week for men, 7 units per week for women (1 unit is 125 ml wine or 250 ml beer) (IA). In the 2013 version, alcohol consumption was calculated in grams of ethanol per day;
- Heavy drinking of alcohol should be avoided (IIIA). New position;
- Increased consumption of vegetables, fresh fruits, fish, nuts, unsaturated fatty acids (olive oil); consumption of low-fat dairy products; low red meat intake (IA). Experts particularly emphasized the need to increase olive oil consumption;
- Control body weight, avoid obesity (body mass index (BMI) >30 kg/m2 or waist circumference more than 102 cm in men and more than 88 cm in women), maintain a healthy BMI (20-25 kg/m2) and waist circumference (less than 94 cm in men and less than 80 cm in women) to reduce blood pressure and cardiovascular risk (IA);
- Regular aerobic physical activity (at least 30 minutes of moderate dynamic physical activity for 5-7 days a week) (IA);
- Smoking cessation, support and assistance measures, referral of patients to smoking cessation (IB) programs.
Strategy for drug treatment of hypertension
The new Recommendations retain 5 classes of drugs as basic antihypertensive therapy: ACE inhibitors (ACEIs), angiotensin II receptor blockers (ARBs), beta blockers (BBs), calcium antagonists (CAs), diuretics (thiazide and tazide-like (TD), such as chlorthalidone or indapamide) (IA). At the same time, some changes in the position of the BB are indicated. They can be prescribed as antihypertensive drugs in the presence of specific clinical situations, such as heart failure, angina pectoris, previous myocardial infarction, the need for rhythm control, pregnancy or pregnancy planning. Bradycardia (heart rate less than 60 beats/min) is included as absolute contraindications to BBs and chronic obstructive pulmonary disease is excluded as a relative contraindication to their use (Table 6).

Experts placed special emphasis on starting therapy with 2 drugs for most patients. The main argument for using combination therapy as an initial strategy is the well-founded concern that by prescribing one drug with the prospect of further dose titration or adding a second drug at subsequent visits, most patients will remain on insufficiently effective monotherapy for an extended period of time.
Monotherapy is considered acceptable as a starting therapy for low-risk patients with stage 1 hypertension (if SBP<150 мм рт.ст.) и очень пожилых пациентов (старше 80 лет), а также у пациенто со старческой астенией, независимо от хронологического возраста (табл. 7).
Patient adherence to treatment is considered one of the most important components of successful blood pressure control. In this regard, combinations of two or more antihypertensive drugs combined in one tablet have advantages over free combinations. The new 2018 Recommendations increased the class and level of evidence for initiation of therapy from a double fixed combination (the “single tablet” strategy) to IV.
The recommended combinations remain combinations of RAAS blockers (ACEIs or ARBs) with CB or TD, preferably in a single tablet (IA). It is noted that other drugs from the 5 main classes can be used in combinations. If dual therapy is ineffective, a third antihypertensive drug should be prescribed. The triple combination of RAAS blockers (ACE inhibitors or ARBs), AK with TD (IA) retains its priorities as a base one. If target blood pressure levels are not achieved with triple therapy, the addition of small doses of spironolactone is recommended. If it is intolerant, eplerenone, or amiloride, or high doses of TD, or loop diuretics can be used. Beta or alpha blockers may also be added to therapy.

The Recommendations present approaches to the management of hypertensive patients with comorbid conditions. When hypertension is combined with CKD, as in previous Recommendations, it is indicated that it is mandatory to replace TD with loop diuretics when GFR decreases to less than 30 ml/min/1.73 m2 (Table 8), as well as the impossibility of prescribing two RAAS blockers (IIIA) . The issue of “individualization” of therapy is discussed depending on treatment tolerability, kidney function indicators and electrolytes (IIaC).

The algorithm for drug treatment of hypertension in combination with coronary heart disease (CHD) has more significant features (Table 9). In patients with a history of myocardial infarction, it is recommended to include BB and RAAS blockers (IA) in the therapy; in the presence of angina, preference should be given to BB and/or AK (IA).

An obvious choice of drugs is proposed for patients with chronic heart failure (CHF). In patients with CHF and low EF, the use of ACE inhibitors or ARBs and BBs, as well as, if necessary, diuretics and/or mineralocorticoid receptor antagonists (IA) is recommended. If the target blood pressure is not achieved, the possibility of adding dihydropyridine AKs (IIbC) is considered. Since no single group of drugs has proven superior in patients with preserved EF, all 5 classes of antihypertensive agents (IC) can be used. In patients with left ventricular hypertrophy, it is recommended to prescribe RAAS blockers in combination with AK and TD (I A).
Long-term follow-up of patients with hypertension
A decrease in blood pressure develops within 1-2 weeks from the start of therapy and continues over the next 2 months. During this period, it is important to schedule a first visit to assess the effectiveness of treatment and monitor the development of side effects of the drugs. Subsequent monitoring of blood pressure should be carried out at the 3rd and 6th months of therapy. The dynamics of risk factors and the severity of target organ damage should be assessed after 2 years.
Particular attention was paid to the observation of patients with high normal blood pressure and white coat hypertension, for whom it was decided not to prescribe drug therapy. They should be examined annually to assess blood pressure, changes in risk factors and lifestyle changes.
At all stages of patient monitoring, it is necessary to evaluate adherence to treatment as a key reason for poor blood pressure control. To this end, it is proposed to carry out activities at several levels:
- Clinician level (providing information about the risks of hypertension and the benefits of therapy; prescribing optimal therapy, including lifestyle changes and combination drug therapy combined into one pill whenever possible; increasing patient empowerment and feedback ; interaction with pharmacists and nurses).
- Patient level (independent and remote monitoring of blood pressure, use of reminders and motivational strategies, participation in educational programs, self-adjustment of therapy in accordance with simple algorithms for patients; social support).
- Level of therapy (simplification of therapeutic regimens, “one pill” strategy, use of calendar packs).
- Level of the health care system (development of monitoring systems; financial support for interaction with nurses and pharmacists; reimbursement of patients for fixed combinations; development of a national information base for drug prescriptions accessible to doctors and pharmacists; increasing the availability of drugs).
- Expanding opportunities for the use of 24-hour blood pressure monitoring and blood pressure self-monitoring in the diagnosis of hypertension
- Introduction of new target blood pressure ranges depending on age and comorbidities.
- Reducing conservatism in the management of elderly and senile patients. To select tactics for managing elderly patients, it is proposed to focus not on chronological, but on biological age, which involves assessing the severity of senile asthenia, the ability to self-care and tolerability of therapy.
- Introduction of a “one pill” strategy for the treatment of hypertension. Preference is given to prescribing fixed combinations of 2, and, if necessary, 3 drugs. Starting therapy with 2 drugs in 1 tablet is recommended for most patients.
- Simplification of therapeutic algorithms. In most patients, preference should be given to combinations of a RAAS blocker (ACEI or ARB) with a CCB and/or TD. BBs should be prescribed only in specific clinical situations.
- Increased attention to assessing patient adherence to treatment as the main reason for insufficient blood pressure control.
- Increasing the role of nurses and pharmacists in the education, monitoring and support of patients with hypertension as an important component of the overall blood pressure control strategy.
