Clinical syndromes in arterial hypertension. Arterial hypertension: what is it? Syndromes with high blood pressure

Hypertension (arterial hypertension) is the most common disease of the cardiovascular system.

Hypertension is rapidly becoming “younger”; today it is no longer a disease only of older people, but is often found in pregnant women, and is becoming increasingly common in adolescents.

What is arterial hypertension? The answer to this question can be found in the definition of the condition for this disease.

It is characterized by chronically elevated blood pressure, When highest indicator(systolic pressure) exceeds 140 mm Hg. and the lowest (diastolic pressure) is above 90 mm Hg. subject to at least three measurements made in different times in a person who is in a calm state.

Optimal blood pressure readings are 120-130 at 80-89 mmHg. if they are higher, then it is necessary to begin actively treating hypertension. However, few people diagnose this disease on early stage: about 35% of men and 55% of women know about their high blood pressure, treatment arterial hypertension only half of them are engaged, and only 6% of the male population and 20% of the female population control their blood pressure.

The sooner you identify arterial hypertension and begin to keep it under control, the lower the risk of developing complications of hypertension in the future (coronary artery disease, atherosclerosis, kidney disease, decreased testosterone levels in the blood, erectile dysfunction).

Hypertension can be one of the causes of impotence in men.

It is worth noting

The main goal of treating hypertension is to constantly monitor blood pressure in order to avoid even more serious problems with health, since it is impossible to completely cure this disease.

Why is hypertension dangerous?

With prolonged high blood pressure, the walls of blood vessels thicken and lose their ability to relax, this prevents normal blood supply and, as a result, the saturation of tissues and organs with oxygen and other nutrients, reducing their functional activity. Let's take a closer look at why hypertension is dangerous:

  • Hypertensive crisis- the most common exacerbation of arterial hypertension, can occur both in the relatively satisfactory condition of the patient, and can be caused by the psychophysical stress of the patient. Developing at high speed, a hypertensive crisis sharply increases blood pressure, causing severe headache, dizziness, tachycardia or arrhythmia, nausea and vomiting. Those at risk are those who suffer from weather dependence and are in the preclimatic period.
  • Myocardial infarction- complicated by hypertension can occur within a few minutes and lead to fatal outcome. The main symptom is a prolonged pain attack.
  • Stroke- disturbance of blood circulation in the vessels of the brain, hemorrhage in the brain, characterized by a sudden severe headache, which is quickly accompanied by other symptoms from the brain: speech impairment, twisted mouth, paralysis of one part of the body. If you take urgent measures and do capillary bloodletting for hypertension. then this process can be reversible.
  • Angina pectoris- the disease is less transient. Disturbances in the functioning of the heart cause severe emotional overload and fatigue. Accompanied by severe dull pain in the chest area, feeling unwell, may cause frequent vomiting.
  • Heart failure- a chronic condition of the heart muscle in which it is unable to provide oxygen to the organs and tissues of the body. It is characterized by total weakness of the patient, in which he is unable to endure basic physical activity: getting up on his own, walking, etc.
  • Ischemic disease hearts- insufficient blood supply to the coronary arteries, resulting in insufficient nutrition of the heart. If you carefully follow the prescribed treatment for hypertension, it is not difficult to avoid the development of coronary artery disease.
  • Kidney failure- impaired kidney function, destruction of neurons, partial inability to remove toxins from the body. Arterial hypertension is second only to diabetes mellitus. cause of a person developing acute or chronic form renal failure.
  • Distortion of vision- occurs as a result of disruption of the blood supply to the retina and optic nerve. A sharp increase in blood pressure can cause spasm of the artery supplying the optic nerve and damage the integrity of the retinal vessels. Hypertension is dangerous due to pathologies such as retinal hemorrhage or vitreous: the first leads to the formation of a black spot in the field of vision, the second leads to loss of vision in the affected eye.

To avoid any complications that are so dangerous with hypertension, it is necessary to consult a doctor in a timely manner and undergo an examination, which will help determine the stage of development of the disease and prescribe the required treatment.

Degrees of hypertension: classification, forms

Based on the nature of the assessment of one or more criteria, a number of classifications of hypertension are used.

There are stages of development such as origin, form of course, blood pressure level, degree of damage to target organs.

The primary task when diagnosing arterial hypertension is to differentiate the nature of the disease. There are two large groups here:

  • primary or essential hypertension - increased blood pressure is the root cause;
  • secondary or symptomatic arterial hypertension - high blood pressure is caused by diseases of other organs or systems: kidneys, heart, glands internal secretion, lungs, thyroid gland.

According to experts

Treatment of symptomatic hypertension cannot occur without treating the disease that caused it, and begins with it. In some cases, along with the elimination of the underlying disease, hypertension also disappears.

Also, blood pressure, up to a hypertensive crisis, may increase due to improper use of certain medicines, with neuroses, excessive consumption of caffeine and other stimulants.

When diagnosing to choose correct tactics When treating essential hypertension, doctors usually classify the disease according to blood pressure levels. In international practice, there are three degrees of hypertension:

  • Hypertension 1st degree- systolic pressure 140−159 mm Hg. diastolic pressure 90−99 mm Hg. Light form A disease characterized by sudden changes in blood pressure can either return to normal on its own or rise again.
  • Hypertension 2 degrees- systolic 160−179 mm Hg. diastolic 100−109 mm Hg. Moderate form, the increase in pressure is more prolonged, up to normal values rarely falls.
  • Hypertension 3 degrees- systolic above 180 mm Hg. diastolic above 110 mm Hg. Severe form, pressure is consistently at the level of pathological indicators, occurs with severe complications, and is difficult to correct with medications.

Separately, isolated systolic hypertension is distinguished; it occurs in about a third of elderly people with arterial hypertension. This form is caused by age-related loss of elasticity of large vessels, often accompanied by myocardial infarction, coronary heart disease, congestive heart failure and left ventricular hypertrophy. Blood pressure indicators: systolic up to 160 mm Hg. and above, diastolic - below 90 mm Hg.

Helpful information

It is worth noting another minor group - the so-called “white coat hypertension”, when, under the influence of psycho-emotional factors, a person’s blood pressure increases only at the time it is measured by a medical professional. In such cases, the diagnosis is clarified by repeated pressure measurements in a quiet home environment.

In addition to the degree of hypertension, when making a diagnosis, risk factors that can lead to complications of the cardiovascular system and stage are also assessed. clinical course diseases:

  • Transistor ( initial stage) hypertension. The increase in pressure is periodic, returning to normal values; Blood pressure lowering drugs are not used.
  • Labile hypertension. An increase in blood pressure is directly related to the provoking factor: stress, severe psychological or physical stress. To stabilize the pressure, drug treatment is necessary.
  • Stable arterial hypertension. Persistent increase in blood pressure, which requires serious supportive therapy.
  • Malignant form. Increasing blood pressure to very high levels, the disease quickly progresses and leads to the development of serious complications.
  • Crisis form. Characterized by periodic hypertensive crises against a background of normal or slightly elevated blood pressure.

Assessment of hypertension severity and risk possible complications is possible only on the basis of a thorough examination: general and biochemical tests, Ultrasound of the heart and other organs, ECG, fundus examination. Full examination A patient with arterial hypertension is usually treated as an inpatient.

High blood pressure is the main warning sign of hypertension in both men and women

Symptoms of hypertension may be absent for quite a long time, and if a person does not constantly use a blood pressure monitor, he can find out about his disease, having already begun to treat its complications.

Often hypertension has no manifestations at all, except for its main symptom - persistent high blood pressure.

Moreover, the concept of “persistent” or “chronic” is key here, since in a number of situations (stress, fear or anger) pressure can increase and then return to normal on its own. However, few people control their blood pressure levels, so you should pay attention to the following symptoms indicating the development of arterial hypertension:

  • Headache. Most often it appears in the occipital, parietal region or temples. It can occur both at night and immediately after waking up. As a rule, it intensifies with mental or physical activity. Sometimes accompanied by swelling of the eyelids and face.
  • Dizziness. Sometimes even with little physical effort: coughing, turning or tilting the head, or sudden rise.
  • Pain in the heart area. They occur not only during emotional stress, but also at rest. Both long-term aching, squeezing pain and short-term, stabbing pain are possible. They do not disappear after taking nitroglycerin.
  • Palpitations.
  • Noise in ears.
  • Visual impairment: blurred vision, fog, spots before the eyes.
  • Arterial damage: cold extremities, intermittent claudication.
  • Swelling of the legs. Indicate a violation of the excretory function of the kidneys or heart failure.
  • Dyspnea. Occurs both during physical activity and at rest.

It is important to know

Hypertensive crisis - emergency, caused by excessively high blood pressure, can also be considered symptoms of stage 2 and 3 hypertension. At the same time, patients with arterial hypertension of the 1st degree, strictly following the doctor’s recommendations and following a diet for hypertensive patients, can achieve complete disappearance of the unpleasant symptoms of the disease.

It cannot be said that the symptoms of hypertension in men and women are significantly different, but in fact, men are indeed more susceptible to this disease, especially age group from 40 to 55 years. This is partly due to the difference physiological structure: men, unlike women, have greater body weight, and accordingly, the volume of blood circulating in their vessels is significantly higher, which creates favorable conditions for high blood pressure.

On the other hand, women are more responsible for their health, the right image life. The number of stressful situations at work, alcohol consumed and cigarettes smoked is higher in men, but this no longer refers to the symptoms of hypertension, but to the reasons for its development.

Treatment of hypertension with medications and folk remedies

Treatment of hypertension, as well as other diseases that are difficult to diagnose and require constant therapy ( diabetes, allergies, prostatitis and impotence), should be compiled and prescribed only by a specialist. If restrictions on food, consumption table salt, giving up alcohol and smoking, avoiding stress and other correctable causes of hypertension does not help normalize blood pressure levels, pills will be prescribed for high pressure.

Methods for treating hypertension

In the treatment of hypertension folk remedies side effects, as a rule, are absent. You don’t have to run to the pharmacy for expensive medications and stand in line for the doctor to write out another prescription. All you need to do is take some time for yourself, change your diet and learn how to manage stress.

Causes of high blood pressure and the development of hypertension

The causes of arterial hypertension are still not completely clear; both internal systems body and external factors. If with symptomatic hypertension the causes of increased blood pressure are caused by other diseases, then with essential hypertension, and this form is registered in 85% of cases, the exact causes of high blood pressure cannot be established; it arises independently.

There are many risk factors that contribute to persistent high blood pressure bloodstream, they are usually considered to be the causes of hypertension. These include:

  • Age, for men over 55 years, for women over 65 years. With age, the walls of blood vessels lose their elasticity, which increases their resistance to blood flow, and as a result, the pressure increases.
  • Hereditary predisposition.
  • Floor. As already mentioned, men are more likely to suffer from arterial hypertension.
  • Impaired fat metabolism, obesity (men with a waist size of more than 102 cm, women with a waist size of more than 88 cm).
  • Diabetes.
  • Smoking. Causes an immediate rise in blood pressure, and smokers with many years of experience are susceptible to vascular diseases.
  • Alcohol abuse. The blood pressure of a person who stops drinking drops by at least fifteen points.
  • Excessive salt intake. Excessive intake of sodium, the main component of table salt, into the body is one of the most significant causes of increased blood pressure in hypertensive patients: sodium chloride prevents the removal of fluid from the body, which increases the already high vascular tone of the patient. Remember, the average person consumes three times the amount of salt that he needs, learn not to add salt to your food.
  • Insufficient physical activity, sedentary lifestyle.
  • Exposure to stress.
  • Cholesterol metabolism disorder.
  • Insufficient intake of potassium from food.
  • Increased level of adrenaline in the blood.
  • Congenital heart defects.

Various kidney diseases, late toxicosis of pregnant women, regular use of certain medications, in some cases this also applies to oral contraceptives, should be attributed to the causes of secondary hypertension.

The above risk factors can be divided into two large groups :

  • Which can be eliminated independently or with the help of doctors: treat obesity, reduce blood cholesterol levels, the number of cigarettes smoked, alcohol or salt consumed, lose excess weight and so on.
  • Which cannot be avoided: age and hereditary predisposition.

Therefore, those who are in the so-called second risk group need to especially carefully monitor their health and monitor and prevent arterial hypertension. And everyone who has at least one of the above factors should constantly monitor their blood pressure levels and, of course, lead a normal and active lifestyle.

Complaints: headache, often in the occipital and parietal regions, heaviness in the back of the head, dizziness, noise in the head, “flying spots” before the eyes, stabbing or aching pain in the precordial region.

Inspection and palpation: often hypersthenic constitution, increased nutrition, facial hyperemia. The apex beat is diffuse, resistant, shifted to the left, sometimes downward. The pulse is hard and full.

Percussion: the left border of relative cardiac dullness is shifted to the left in the IV-V intercostal spaces due to the enlargement of the left ventricle. In later stages - expansion of boundaries vascular bundle(in the 2nd intercostal space).

Auscultation: The first tone at the apex is weakened, the accent of the second tone is over the aorta. As changes in the left ventricle increase, functional systolic murmur may appear at the apex of the heart and cardiac arrhythmias.

Instrumental research methods

X-ray: Signs of left ventricular hypertrophy, aortic configuration of the heart, the aorta is dilated and thickened.

ECG: Levogram: R I >R II >R III, S III >S I, RV 5 - 6 >RV 4. Signs of left ventricular overload: S-T segment in I, aVL, V 5-6 below the isoline. There may be flattened, smoothed or even negative T in I, aVL, V 5-6.

Ocular fundus: retinal arteries are narrowed, tortuous, veins are dilated. Symptoms of Guna-Salus I, II, III degrees. Symptoms of "copper" and "silver" wire.

Ultrasound of the heart: thickening of the wall of the left ventricle.

Essential arterial hypertension

This disease, characterized by an increase in blood pressure, is not associated with any independent damage to organs and systems. It occurs, according to various authors, in 15-30% of the entire adult population. Among all arterial hypertension, essential arterial hypertension (EAH) accounts for 90-95% of cases. A synonym for EAH is “hypertension.” However, according to the recommendations of WHO experts, the term “hypertension” is not currently used.

Etiology and pathogenesis

The reasons for the development of EAH are still unclear. We can only say with confidence that this is a multifactorial disease and among predisposing factors highlight:

    neuropsychic trauma, frequent emotional stress;

    hereditary constitutional features;

    occupational hazards (noise, constant eye strain, heavy physical activity);

    dietary habits (excessive consumption of table salt, deficiency of calcium, magnesium, excessive intake of cadmium);

    age-related restructuring of the diencephalic-hypothalamic structures of the brain (during menopause);

    traumatic brain injuries;

    intoxication (smoking, alcohol);

    violation of fat metabolism (obesity);

    physical inactivity.

Factors that determine the prognosis for hypertension (risk stratification criteria) are outlined below.

A very important role is played in the occurrence of EAH burdened heredity . It is believed that the genetic defect is associated with a defect in plasma membranes and is expressed in a violation of the transport of monovalent cations and calcium. However, for the disease to occur, the presence of predisposing factors (stress, smoking, physical inactivity, etc.) is necessary. According to modern concepts, the pathogenesis of hypertension is a complex complex of metabolic, neurohumoral, structural, hemodynamic disorders leading to the development of the disease. The disease is based on a disruption of normal neurogenic and/or humoral regulation vascular tone with the gradual formation of organic changes in the heart and vascular bed, the development of ischemia of various organs and systems and their functional failure.

The most studied parts of the pathogenesis of hypertension are:

1. Strengthening pressor factors:

    activation of the sympathoadrenal system (SAS);

    increased production of various neuropetic hormones (adrenaline, norepinephrine, vasopressin, prolactin, serotonin, etc.);

    activation of the renin-angiotensin-aldosterone system (RAAS). This link is given the greatest importance.

2. Depletion of depressor factors:

    decrease in the level of prostaglandins, activity of the kinin-kallikrein system;

    decreased production of atrial natriuretic factor (NAUF);

    decrease in the production of endothelial relaxing factor - nitric oxide (NO).

    Metabolic mechanism of hypertension development (development of metabolic syndrome). With this syndrome there is a combination of obesity, diabetes mellitus, and hyperlipidemia. In this case, hyperinsulinemia develops with simultaneous insulin resistance. Hypertension against the background of metabolic syndrome is particularly persistent, malignant, and resistant to treatment.

What is arterial hypertension? The concept means a persistent increase in blood pressure during cardiac systole (SBP) above 140 mm Hg. Art. and during diastole (DBP) more than 90 mm Hg.

This is the main thing pathological condition organism that creates everything the necessary conditions for the development of disturbances in the functioning of the heart muscle and neurocirculatory dysfunctions.

The term “Hypertension” was first introduced by the Soviet academician F.G. Lang. The significance of this diagnosis is general meaning with the term widely used abroad, “essential hypertension” and means an increase in blood pressure levels above normal without any obvious reason.

Symptoms of pathology

Signs of high blood pressure often cannot be recorded, which makes the disease hidden threat. Persistent hypertension is manifested by headaches, fatigue, compression in the back of the head and temples, nosebleeds, and nausea.

Classification arterial hypertension:

SBP is within normal limits for healthy person should be at the level of 120-129 mmHg, and normal DBP should be 80-84 mmHg. Systolic pressure from 130 to 139 mmHg is called high normal, and diastolic pressure is from 85 to 89 mmHg. Art.

Coding according to ICD-10

Diseases characterized by high blood pressure I10-I15

There is a scale for assessing cardiovascular risk (CVR), which affects the further course and development of the disease. To determine CVR, it is important to take into account not only the level of blood pressure, but also concomitant dysfunctions of other organs. Thus, the risk is low, medium, high and very high.

Complications after arterial hypertension

Causes and risk factors

Risk factors for arterial hypertension, which I take into account when making a diagnosis and the degree of cardiovascular risk:

  1. Males are more prone to developing disorders of the heart and blood vessels at the age of over 55 years;
  2. Cases of arterial hypertension are more common in people over 65 years of age;
  3. Smoking helps to reduce the tone of the vascular walls and increase blood pressure on them;
  4. Blood lipid disorders (increased number of low-density lipoproteins and decreased number of high-density lipoproteins);
  5. Increased blood glucose levels;
  6. Obese people almost always suffer from hypertension;
  7. Unfavorable family history of heart and vascular diseases.

To determine the SSR, the following factors are taken into account:

  1. Increased pulse pressure;
  2. Signs of hypertrophy of the left chambers of the heart, in particular the ventricle, on EchoCS and ECG;
  3. Availability chronic illness kidneys and concomitant microalbuminuria;
  4. Formation of atherosclerotic plaques on the walls of the carotid arteries;
  5. Diabetes;
  6. Pathology of cerebral vessels;
  7. Cardiac ischemia;
  8. Pathological changes in the retina of the eye.

Blood pressure measurement technique

How to measure blood pressure correctly? To measure blood pressure levels in the arterial bed, various devices. The doctor measures your blood pressure or nurse. The patient can also take the measurement independently using an automatic tonometer.

The patient should be in a sitting position, with his arm raised to the level of his heart, in a relaxed state. Avoid taking coffee or tea, sympathomimetics, or physical activity a few minutes before measurement.

A special cuff is placed on the arm so that its lower edge is 2 cm higher elbow joint. Cuffs come in different sizes! Obese people need to measure their blood pressure only with a 20*42cm cuff. or 16*38cm.

Using a special rubber bulb, air is pumped until the pulse on the radial artery ceases to be recorded. Then the air slowly descends. Using a phonendoscope, you need to register Korotkoff sounds. When the first tone is heard, the SBP is recorded, and when the last tone is heard, the DBP level is recorded. The measurement is carried out twice. Subsequently, the pressure is determined on the arm on which the highest was recorded.

Self-monitoring of blood pressure is actively used, which helps to establish dynamic changes in pressure levels. ABPM is often recommended in combination with it.

ABPM is 24-hour monitoring of a patient's blood pressure.

For this method, a special portable device with a cuff is used, which the patient carries with him throughout the day. The device constantly records changes in blood pressure arterial blood in line. The patient records his actions and the time of taking certain medications during monitoring.

Indications for ABPM and SCAD:

  1. Suspicions that blood pressure rises when you see a doctor (psychological factor);
  2. The presence of damage to the heart, kidneys or other organs without a clear increase in blood pressure;
  3. If blood pressure fluctuates during several visits to the doctor;
  4. When blood pressure decreases during a change from a horizontal to a vertical position (standing);
  5. With a significant drop in blood pressure during sleep in the daytime;
  6. If nocturnal hypertension is suspected.

By using sphygmogram results and brachial pressure measurements, central BP levels can be calculated. To begin with, complaints and anamnesis of life and illness are collected. Height and weight are then measured to calculate the patient's body mass index.

Diagnosis of pathology

  1. Normalization of nutrition. Increasing the amount of food plant origin, reducing the amount of salt intake to 5 g per day, limiting the intake of fatty foods;
  2. Exclusion of alcoholic beverages;
  3. It is recommended to give up cigarettes. Smoking adversely affects cardiovascular system;
  4. Dosed physical activity (30 minutes every other day, aerobic exercise). It is advisable not to engage in strength sports;
  5. Losing weight in case of obesity.

Drug treatment


must be prescribed by a doctor. Self-medication for hypertension is not only ineffective, but can also cause the development of a hypertensive crisis.

Types of blood pressure medications:

  1. Angiotensin-converting enzyme inhibitors and drugs that block angiotensin 11 receptors. Drugs in these groups are very often used in the treatment of arterial hypertension. They are especially effective if the patient has hyperfunction of the angiotensin-aldosterone system of the kidneys. Sometimes when using ACE inhibitors, a phenomenon of “escape” effect may occur, as the angiotensin enzyme changes its synthesis pathway. This effect is not observed when taking BAP.
  2. Calcium antagonists (CAs) reduce peripheral resistance of the vascular walls, which lowers blood pressure. There are three groups of AKs:
    — Dihydropyridines (Amlodipine, Nifedipine);
    — Phenylalkylamines (Verapamil);
    - Benzothiazepines (diltiazem).

    Drugs of this series protect the vascular wall from the imposition of thrombotic masses, prevent the occurrence of atherosclerosis, and provide a protective function for the kidneys and brain.

  3. Thiazide diuretics (hydrochlorothiazide) increase the excretion of chlorine and sodium in the urine, reduce the volume of circulating blood, thereby lowering blood pressure. However, when using such drugs in high doses, disturbances in the metabolic process in the body may occur. Most often they are combined with ACEI or BAP. Aldosterone receptor antagonists (spironolactone) reduce blood pressure by binding to aldosterone receptors. This drug reduces the excretion of potassium and magnesium in the urine.
  4. Beta-blockers (bisoprolol, nebivolol, carvedilol). Prescribed if the patient has suffered a myocardial infarction or cardiac dysfunction. The effect is to reduce the frequency and strength of contractions of the heart muscle. However, beta blockers negatively affect the body's metabolism. They prevent the development of cerebral vascular pathology and prevent the occurrence of strokes.

The patient can take as 1 prescribed medicinal product, and carry out combined treatment (2-3 drugs).

There are other classes of drugs against hypertension:

  1. Imidazoline receptor agonists (rilmenidine, moxonidine). They have a positive effect on the body’s carbohydrate metabolism and help the patient lose weight;
  2. Alpha blockers (prazosin). They also have a positive effect on metabolic processes in the body. Used in combination with other antihypertensive drugs.
  3. Renin inhibitors (direct). The drug Aliskiren is used, which reduces the amount of renin in the blood and angiotensin.

Combinations of antihypertensive drugs are used; they must have similar pharmacokinetic properties and produce the expected effect. There are such rational combinations of drugs: diuretic and ACEI, diuretic and ARB, ACEI and calcium antagonists, diuretic and calcium antagonists, ARB and calcium antagonists and others, at the discretion of the attending physician.

If the patient has suffered a myocardial infarction or stroke, it is recommended to take aspirin in various doses. Aspirin also prevents the formation of atherosclerotic plaques on the walls of blood vessels.

If, according to laboratory data, the patient has changes in the lipid profile, statins are prescribed.

Treatment of hypertensive crisis

A hypertensive crisis is a sudden occurrence of an increase in blood pressure above 160/120 mmHg, accompanied by certain clinical manifestations. Crises can be uncomplicated or complicated (there is a threat to the patient’s life).

Treatment of a complicated crisis is carried out in a therapeutic or cardiological inpatient department. It is necessary to reduce blood pressure by 25%, but not in all cases.

The following drugs are used:

  • Vasodilators (nitroglycerin, sodium nitroprusside, enalaprilat);
  • Beta blockers (metoprolol);
  • Ganglion-blocking substances;
  • Diuretics;
  • Neuroleptics.

An uncomplicated crisis is stopped more quickly; oral antihypertensive drugs are used (captopril, clonidine, moxonidine, nifedipine, etc.).

Prevention

During the period of exacerbation of the disease, it is important to exclude salty and spicy foods and alcohol from the diet. Spend more time relaxing, avoiding heavy mental and physical stress.

Treatment of arterial hypertension is selected for each individual. The patient’s daily routine and diet, body type and many other factors are taken into account. The medication intake is prescribed in detail and explained by the attending physician. It is extremely important that the patient understands the importance of treatment and follows all the doctor’s recommendations.

CONSULTATION WITH YOUR DOCTOR IS REQUIRED

In contact with

IN last years The incidence of hypertension has increased, reaching 40% of the population in some countries, and the age at which it is first detected has decreased. This problem is very urgent, as it leads to the development of irreversible changes in internal organs and death.

What is arterial hypertension is an increase in systolic pressure above 141 millimeters of mercury (mmHg) and/or above 91 mmHg, recorded in at least two doctor measurements with an interval of several days.

Classification

The most common form is a mixed form, in which both systolic and diastolic pressure increases. Isolated hypertension occurs less frequently - an increase in only one type of pressure. Latest form typical for older people.

Due to its occurrence, two types of arterial hypertension can be distinguished:

  1. Primary – idiopathic or essential, the cause of which cannot be established. Occurs in 90% of cases. The diagnosis of primary hypertension is established after excluding all possible reasons increase in blood pressure.
  2. Secondary is only a symptom of a disease, and not an independent nosology, that is, the reason for the increase in pressure is always clear.

All arterial hypertension can be divided into 3 degrees depending on the level of pressure increase:

  1. Optimal blood pressure - sBP< 120, дАД
  2. Normal – accordingly< 120-129/80-84 мм.рт.ст.
  3. High normal - SBP is in the range of 130-139 mmHg, and DBP is 85-89 mmHg.
  • I degree – 140-159/90-99 mmHg.
  • II degree – increase in SBP from 160 to 179 and DBP from 100 to 109 mmHg.
  • III degree – SBP from 180 and >, DBP > 110 mmHg.

Classification by stages of the disease:

  • Stage I – no target organ damage is observed;
  • Stage II – disruption of the functioning of one or more target organs;
  • Stage III – a combination of target organ damage with associated clinical diseases.

Types of isolated arterial hypertension: systolic - upper pressure is more than 141, lower - less than 89, diastolic - upper pressure is normal, lower pressure is more than 91.

Forms of arterial hypertension according to the level of pressure increase:

  • mild hypertension – corresponds to the first degree of increase in blood pressure;
  • moderate hypertension – corresponds to the II degree of increase in blood pressure;
  • severe hypertension – corresponds to the third degree of increase in blood pressure.

Reasons for development

Arterial hypertension is a syndrome that can be a manifestation of many diseases. There are a number of predisposing factors:

  • heredity;
  • age (for men over 45 years old, for women over 65 years old);
  • physical inactivity;
  • obesity – increases the risk of hypertension by 5-6 times, due to the occurrence of metabolic syndrome. Excess weight also contributes to the occurrence of atherosclerosis, which leads to vasoconstriction and increased blood pressure;
  • Increased consumption of sodium chloride (table salt) more than 6 g per day contributes to an increase in blood pressure. Sodium increases osmotic pressure, which causes an increase in circulating blood volume and cardiac output;
  • insufficient potassium intake;
  • excessive consumption of alcoholic beverages disrupts the central regulation of blood pressure;
  • nicotine promotes damage to the vascular endothelium and activation of local vasoconstrictor factors.

Arterial hypertension syndrome can occur in the following diseases:

  • glomerulonephritis;
  • narrowing of the blood vessels of both kidneys;
  • kidney inflammation;
  • diabetic angiosclerosis of the renal vessels;
  • renal amyloidosis;
  • hyperthyroidism;
  • pheochromocytoma - a hormone-producing tumor of the adrenal glands;
  • primary and secondary hyperaldosteronism;
  • aortic valve insufficiency in the heart;
  • post-traumatic encephalopathy;
  • aortic pathology - coarctation or atherosclerosis;
  • Page's disease - damage to the hypothalamus;
  • encephalitis, meningitis;
  • subarachnoid hemorrhages.

Thus, the causes of persistent hypertension are very diverse, and a thorough examination is necessary to identify them.

Mechanism of increased blood pressure

First of all, you need to understand what hypertension is. From ancient Greek this word is translated as an increase in pressure in any system and is not necessarily related to the vascular system of the body.

Blood pressure is determined by three main factors:

  1. Total peripheral vascular resistance depends on the condition of the vascular wall and the degree of narrowing of the lumen of blood vessels.
  2. Cardiac output is a value that depends on the possibility of contraction of the left ventricular myocardium.
  3. Circulating blood volume.

A change in any of these factors leads to a change in blood pressure.

The pathogenesis of arterial hypertension is represented by three main theories:

  1. The first is theory central genesis. According to this theory, arterial hypertension occurs due to impaired blood supply to the cortical centers of pressure regulation. This happens most often due to prolonged neurosis, psychological trauma and negative emotions.
  2. The second theory is hyperactivation of the sympathetic-adrenal system. Etiology of arterial hypertension in in this case is an inadequate response of the hormonal system to psycho-emotional and physical stress. As a result of the increased response of the sympatho-adrenal system, contraction of the left ventricle increases, cardiac output and blood pressure increase.
  3. The third theory is the theory of activation of the renin-angiotensin-aldosterone system (RAAS). The pathophysiology of arterial hypertension in this case is a change in the secretion of renin by the kidneys. Under the influence of this hormone, angiotensin-1 is formed, which is converted into angiotensin-2, which has a vasoconstrictor effect.

The mechanism of development of arterial hypertension also includes changes in the following indicators:

  • mineralacolocorticoids (in particular, aldosterone) – retain sodium ions in the body, which leads to fluid retention and an increase in blood volume;
  • atrial natriuretic factor - promotes the removal of sodium from the body, reducing blood volume and blood pressure. When the amount of this factor decreases, uncontrolled arterial hypertension occurs;
  • disruption of ion transport through cell membrane– with vascular hypertension, the permeability of the membrane for certain ions: sodium and calcium increases, as a result of which their intracellular concentration increases, which leads to an increase in the tone of the vascular wall, a narrowing of its lumen and an increase in blood pressure.

Simply put, an increase in blood pressure occurs due to an increase in vascular resistance, increased heart rate, or an increase in circulating blood volume.

Clinical and pathophysiological changes in target organs

Before moving on to the clinic, you need to understand the following: the totality of the symptoms of the disease and are the concepts of arterial hypertension and essential hypertension identical?

Hypertension syndrome is a symptom complex characteristic of a number of diseases listed above. Hypertension, in turn, is an independent disease; the causes of hypertension in this case are not clear.

Symptoms of arterial hypertension depend on which target organ is affected first. The latter include:

  1. Heart.
  2. Brain.
  3. Kidneys.
  4. Vessels.

Pathological changes in blood vessels primarily affect their walls: hypertrophy, proliferation and infiltration of plasma proteins occur. These changes in the vascular wall cause its thickening and narrowing of the lumen blood vessels. This leads to a decrease in functioning vessels and hypoxia of the organs they supply.

Changes in the heart begin with myocardial hypertrophy. Subsequently, heart failure occurs and there is a high risk of sudden cardiac death.

In the kidneys, the renin-angiotensin-aldosterone system is first activated and depressor mechanisms are inhibited. Subsequently, structural and degenerative changes in the renal arteries, which leads to atrophy of the renal nephrons and a primary wrinkled kidney is formed.

The same degenerative changes occur in the brain as in the renal vessels. This leads to the development of dyscirculatory encephalopathies, ischemic and hemorrhagic strokes.

Simply put, high blood pressure leads to thickening of the vascular wall and increased stress on the heart. This causes thickening of the myocardium and the development of heart failure. Due to deterioration of blood supply, other target organs - the brain, kidneys and eyes - also suffer.

Clinical picture

Arterial hypertension itself has no symptoms. Most patients with this disease do not complain of anything at all, high blood pressure discovered by chance.

Clinical manifestations arterial hypertension depend on which organs are currently affected. Patients with benign arterial hypertension may present the following complaints:

  • Headache may be the very first and main symptom. There are several types of headaches:
  1. dull, non-intense, characterized by a feeling of heaviness in the forehead and back of the head. It appears most often at night or in the morning, and intensifies with a sudden change in head position and even minor physical activity. This pain is caused by a violation of the venous outflow of blood from the vessels of the skull, their overflow and stimulation of pain receptors;
  2. cerebrospinal fluid – bursting, diffuse throughout the head, can be pulsating. Any tension causes increased pain. It occurs most often in the late stages of hypertension or in the presence of pulse hypertension. As a result, the vessels suddenly become overfilled with blood and its outflow is difficult;
  3. ischemic – dull or aching in nature, accompanied by dizziness and nausea. Occurs with a sharp increase in blood pressure. A sharp spasm of blood vessels occurs, as a result of which the blood supply to the brain tissue is disrupted.
  • Pain in the heart area - cardialgia, not ischemic in nature, the coronary vessels are in order, while the pain is not relieved by the sublingual use of nitrates (nitroglycerin under the tongue) and can occur both at rest and during emotional stress. Sports activities are not a provoking factor.
  • Shortness of breath - at first it occurs only when playing sports, with the progression of hypertension, it can also occur at rest. Characterizes a disturbance in the functioning of the heart.
  • Edema - most often found on the legs due to stagnation of blood in the big circle circulatory problems, sodium and water retention, or renal dysfunction. The appearance of hematuria and hypertension in children simultaneously with edema is characteristic of glomerulonephritis, which is very important to remember when making a differential diagnosis.
  • Visual impairment - manifests itself in the form of blurred vision, the appearance of a veil or flickering spots. Occurs due to damage to the retinal vessels.

Chronic arterial hypertension causes kidney damage with the development of renal failure and corresponding complaints of renal origin, which will be discussed below. Chronic hypertension also leads to the development of discirculatory encephalopathy, which is characterized by decreased memory, attention and performance, sleep disturbance (excessive sleepiness during the day, combined with insomnia at night), dizziness, tinnitus and depressed mood.

When collecting anamnesis (detailed questioning of the patient), in the medical history it is necessary to record the family history and causes of arterial hypertension in close relatives, to clarify the time of the onset of the first clinical symptoms, note concomitant diseases. The presence of risk factors and the condition of target organs should also be assessed.

Complaints about arterial hypertension can be heard from patients very rarely, more often in old age, and therefore it is necessary to conduct a very careful survey.

It should also be remembered that arterial hypertension is much less common in adolescents than in older people.

The main sign of hypertension, which a doctor can identify during an examination, is an increase above 140/90 mmHg. Art. Signs of arterial hypertension during examination can be very different: from swelling to lower limbs to cyanosis of the skin. All of them characterize ischemia and hypoxia internal organs.

At benign hypertension changes in organs occur gradually, while in malignant cases a sharp rise in pressure is combined with rapidly progressing changes in target organs.

The definition of arterial hypertension announces specific figures for the increase in pressure, and therefore the formulation of a diagnosis is possible only when these figures are established in double measurements over several days. Patients with arterial hypertension most often require 24-hour blood pressure monitoring.

Hypertensive crisis

Hypertensive crisis is an emergency condition, consisting of a sharp increase in blood pressure to high numbers and characterized by a sharp deterioration in the blood supply to all internal organs, in particular vital ones.

It occurs when the body is exposed to various unfavorable factors; it cannot be predicted, which is why uncontrolled hypertension is dangerous. The urgency of the problem also lies in the fact that in the absence of timely emergency care Possible death.

To provide emergency assistance the patient must be immediately taken to the hospital, where his blood pressure is quickly reduced with medications.

Students medical institutes They study first aid for a hypertensive crisis at the Department of Propaedeutics of Internal Diseases, and therefore it would be best for a random passer-by not to try to provide help, but to call an ambulance.

Treatment of high blood pressure

Many people wonder how to treat arterial hypertension, and whether it is possible to treat hypertension at home. This will be discussed below.

Treatment of arterial hypertension with non-drug means consists of reducing and eliminating the following risk factors:

  • smoking and drinking alcohol;
  • weight normalization;
  • sufficient physical activity;
  • normalization higher level blood lipids and a decrease in the amount of low-density lipoproteins.

The latter can be achieved both with medication and with the help of proper nutrition. The diet for arterial hypertension consists of reducing the consumption of sodium chloride (table salt) to 3-3.5 g per day, introducing more potatoes (baked in their skins) into the diet, seaweed and seaweed, beans and peas (sources of potassium and magnesium).

Treatment of arterial hypertension with medications begins in cases where the patient’s blood pressure remains at 140 or above for more than three months in a row and does not decrease during the day, despite changes in lifestyle.

The principles of treatment of arterial hypertension are as follows:

  1. Treatment should begin with a minimum dose of antihypertensive drugs, and increase it only if there is no effect.
  2. Focus on lifelong medication to maintain optimal blood pressure and reduce the risk of complications.
  3. When choosing a drug, give preference to long-acting drugs, so that a single dose in the morning is possible.
  4. It is recommended to start treatment with monotherapy, and only in the absence of positive dynamics move on to a combination of drugs from different groups.

The following types of antihypertensive drugs are distinguished:

  • beta-blockers – bisoprolol, nebivolol, carvedilol;
  • slow calcium channel blockers – amlodipine, felodipine;
  • angiotensin-converting enzyme (ACE) inhibitors – captopril, enalapril, lisinopril, ramipril, perindopril;
  • angiotensin II receptor blockers - losartan;
  • diuretics – hypothiazide, indapamide.

In older people, when treating arterial hypertension, it is recommended to start with slow calcium channel blockers. Components that alter the metabolism of glucose and insulin should be avoided in drug formulations. The main goal of treatment in older people is to prevent fatal complications.

When formulating a diagnosis of arterial hypertension, one should most fully characterize all the features of the course and the presence of complications in order to determine the most correct treatment tactics for the patient.

Thus, hypertension is a very multifaceted and insidious disease. It is important not only to notice it in time, but also to start correct treatment. Then the risk of complications will be minimal.

Arterial hypertension- a group of diseases in which the leading symptom is a persistent increase in blood pressure above 140/90 mm. rt. Art.e in persons not receiving antihypertensive therapy

By etiology it is divided:

1. Essential or primary arterial hypertension (hypertensive disease).

2. Secondary (symptomatic) hypertension (renal, endocrine, hemodynamic, neurogenic).

n Hypertension is a disease of the cardiovascular system that develops as a result of primary dysfunction (neurosis) of higher vasoregulatory centers and subsequent neurohormonal and renal mechanisms, characterized by arterial hypertension, functional, and in severe stages – organic changes in the kidneys, heart, central nervous system. Accounts for up to 95% of all cases of chronic high blood pressure.

n The causes of essential hypertension have not been precisely established. It is believed to develop through a combination of hereditary predisposition to the disease and adverse influences external factors(stress, excessive consumption of table salt, low level physical activity, smoking, alcohol abuse); Obesity plays an important role. An increase in blood pressure may be due to an increase in total peripheral resistance as a result of narrowing arterial vessels, increased cardiac output, or a combination of these factors. Activation of the sympathoadrenal and renin-giotensin systems plays an important role in this process.

CLASSIFICATION OF HYPERTENSION DISEASE

By stage

Stage I there are no changes in target organs.

Stage II – there is target organ damage (LV myocardial hypertrophy, retinal angiopathy, moderate proteinuria).

Stage III the presence of one or more concomitant

(associated) clinical conditions:

Consequences of stroke;

Hypertensive retinopathy (hemorrhages and

exudates, swelling of the optic nerve nipple);

Creatinemia (more than 2.0 mg/dl);

Dissecting aortic aneurysm.

According to the degree of blood pressure increase.

Degree IBP 140-159/90-99 mmHg.

Grade IIBP 160-179/100-109 mmHg.

Grade IIIBP 180/110 mmHg. and higher

n Isolated systolic hypertension – systolic blood pressure >140 mmHg. and diastolic<90 мм.рт.ст.

n Malignant hypertension – diastolic blood pressure more than 110 mmHg. and the presence of pronounced changes in the fundus (retinal hemorrhages, papilledema

In patients with hypertension, the prognosis depends not only on blood pressure levels, but also on associated risk factors and the degree of target organ involvement and associated clinical conditions. In this connection, stratification of patients depending on the degree of risk has been introduced into the modern classification.

RISK FACTORS for headache:

1. Men over 55 years of age;

2. Women over 65 years of age;

3. Smoking;

4. Cholesterol >6.5 mmol/l;

5. Heredity (for women under 65 years of age;

6. for men under 55 years old);

7. Diabetes mellitus.

8. Abdominal obesity(waist circumference more than 102 cm in men, more than 88 cm in women)

Target organ damage:

1. Left ventricular hypertrophy;

2. Narrowing of retinal vessels;

3. Proteinuria, hypoalbuminuria or higher. creatinine level up to 2 mg/dl (up to 175 µmol/l);

4. Atherosclerotic changes in the arteries.

Accompanying illnesses or complications of hypertension:

n heart: HF, angina, MI;

n brain: violations cerebral circulation;

n ocular fundus: hemorrhages and exudates in the retina, swelling of the optic nerves;

n kidneys: renal dysfunction, increased. creatinine above 2 mg/dl (above 175 mol/l);

n vessels: aortic dissection, occlusive arterial diseases;

n diabetes mellitus

Syndromes in hypertension

1. Arterial hypertension syndrome.

Clinical manifestations :

Blood pressure is more than 139/90 mm Hg. Art.;

upon examination, you may notice pallor or hyperemia of the face;

the pulse is usually symmetrical, firm, high and rapid;

upon percussion, expansion of the vascular bundle;

on auscultation: accent of the second tone over the aorta,

On ECHO-CS, aortic dilatation is > 40 mm.

2. Target organ damage syndrome:

· myocardium (sd cardiomegaly; sd rhythm and conduction disturbances; sd heart failure, sd cardialgia);

· kidneys (initial manifestations of nephropathy – microalbuminuria, proteinuria, a slight increase in creatinine from 1.2 to 2.0%; chronic renal failure).

cerebral vessels (vascular encephalopathy),

includes symptoms associated with functional and organic changes in cerebral vessels. Initial signs headache, dizziness, tinnitus, decreased memory, mental performance.

Changes in the fundus

I degree- segmental or diffuse change arteries and arterioles.

II degree - thickening of the walls, compression of the veins, Salus-Hun symptom (tortuosity and dilatation of the veins).

III degree- pronounced sclerosis and narrowing of arterioles, their unevenness, large and small hemorrhages (foci, stripes, circles), exudations (whipped cotton wool, cotton spots - retinal infarction).

IV degree- the same + bilateral swelling of the optic nerve nipple, blurring of its edges, retinal detachment, star sign.

COMPLICATIONS OF HYPERTENSION:

Left ventricular failure; with a combination of hypertension and coronary artery disease - increased frequency of angina attacks; there is a high probability of myocardial infarction; dissection of aortic aneurysm; cerebral or cerebellar hemorrhages, hypertensive encephalopathy, thrombosis of cerebral arteries; retinal hemorrhages and exudates with and without papilledema; decreased renal blood flow and glomerular filtration rates, slight proteinuria, renal failure; hypertensive crisis.

Hypertensive crisis- this is a relatively sudden, individually excessive increase in blood pressure, with a violation of regional hemodynamics (disorders of cerebral, coronary and renal circulation of varying degrees of severity).

Clinical manifestations :

1. Relatively sudden onset (from several minutes to several hours)

2. Individually high level blood pressure

3. Cardiac complaints (palpitations, irregularities and pain in the heart area, shortness of breath)

4. Complaints of a cerebral nature ("bursting" headaches in the back of the head or diffuse, non-systemic dizziness, a feeling of noise in the head and ears, nausea, vomiting, double vision, flashing spots, flies).

5. Complaints of a general neurotic nature (chills, trembling, feeling hot, sweating).

6. With extremely high blood pressure numbers and a protracted nature of the crisis, the development of acute left ventricular failure (cardiac asthma, pulmonary edema), psychomotor agitation, stunning, convulsions, and short-term loss of consciousness is possible.

When a sudden increase in blood pressure is combined with a headache, the diagnosis of crisis is likely; if there are, in addition, other complaints, it is undoubted.

CORONARY INSUFFICIENCY SYNDROME

Essence: the syndrome is caused by a discrepancy between the myocardial need for oxygen and the possible value coronary blood flow caused by damage to the coronary arteries.

Myocardial oxygen demand depends on the hemodynamic load on the cardiovascular system, heart mass and metabolic rate in cardiomyocytes.

The delivery of oxygen with blood to the myocardium is determined by the state of coronary blood flow, which can decrease with both organic and functional disorders in the coronary arteries.

Main reasons :

1. Atherosclerosis of the coronary arteries with a narrowing of their lumen by 50%.

2. Functional spasm of the coronary arteries by 25% (always against the background of atherosclerosis).

3. Transient platelet aggregates.

4. Hemodynamic disorders (aortic valve defects).

5. Coronaritis.

6. Cardiomyopathies.

Cardiac ischemia

IHD is an acute and chronic heart disease caused by a decrease or cessation of blood supply to the myocardium due to obstruction (atherosclerotic) of one or more coronary arteries (sd coronary insufficiency).

CLASSIFICATION OF CORONARY HEART DISEASE:

1. Sudden coronary death.

2. Angina:

· stable (4 functional classes)

· unstable (new, progressive, spontaneous, resting, early post-infarction)

3. Myocardial infarction (with and without Q)

4. Post-infarction cardiosclerosis.
