Clinical syndromes in arterial hypertension. Arterial hypertension: what is it? High blood pressure syndromes

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

Hypertension is rapidly "getting younger", today it is not only a disease of the elderly, but is often found in pregnant women, and is becoming increasingly common among adolescents.

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

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

The optimal blood pressure values ​​are 120-130 by 80-89 mm Hg. if they are higher, then it is necessary to start actively treating hypertension. However, very few people diagnose this disease at an 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 control their pressure.

The sooner arterial hypertension is detected and started to keep it under control, the less in the future the risk of developing complications of hypertension (coronary artery disease, atherosclerosis, kidney disease, a decrease in testosterone levels in the blood, erectile dysfunction).

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

Its useful to note

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

What is the danger of hypertension

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

  • Hypertensive crisis- the most common exacerbation of arterial hypertension, can occur both with a relatively satisfactory condition of the patient, and be caused by the psychophysical stress of the patient. Developing at a high rate, a hypertensive crisis sharply raises blood pressure, causes severe headache, dizziness, tachycardia or arrhythmia, nausea and vomiting. At risk are those who suffer from meteorological dependence, are in the pre-climatic period.
  • Myocardial infarction- complicated by hypertension can proceed for several minutes and be fatal. The main symptom is a prolonged pain attack.
  • Stroke- impaired blood circulation in the vessels of the brain, cerebral hemorrhage, characterized by a sudden severe headache, which is quickly joined by other symptoms from the brain: speech impairment, crooked mouth, paralysis of one part of the body. If you take urgent measures and make capillary bloodletting for hypertension. then this process can be reversible.
  • Angina pectoris- the disease is less transient. Violation of the heart is caused by strong emotional overload, fatigue. Is accompanied by severe dull pain in the chest area, feeling bad, 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 the total weakness of the patient, in which he is not able to endure elementary physical activity: independent lifting, walking, etc.
  • Ischemic disease hearts- insufficient blood supply to the coronary arteries, as a result of which there is an insufficient nutrition of the heart. With careful adherence to the prescribed treatment of hypertension, it is not difficult to avoid the development of coronary artery disease.
  • Renal failure- impaired renal function, destruction of neurons, partial inability to remove toxins from the body. Arterial hypertension is the second, after diabetes mellitus. the cause of the development in a person of acute or chronic form renal failure.
  • Distorted vision- occurs as a result of a violation of the blood supply to the retina and optic nerve... A sharp increase in blood pressure can cause spasm of the artery that feeds the optic nerve, damage the integrity of the retinal vessels. Hypertension is dangerous by such pathologies as hemorrhage in the retina or vitreous body: 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, which are so dangerous for hypertension, it is necessary to consult a doctor in a timely manner and carry out an examination, which will help determine the stage of development of the disease and prescribe the required treatment.

The degree of hypertension: classification, forms

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

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

The primary task in the diagnosis of 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 treatment of 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 intake of some medicines, with neuroses, excessive use of caffeine, other stimulants.

When diagnosing to select correct tactics Treating essential hypertension, doctors usually classify the condition according to the level of blood pressure. In international practice, there are three degrees of hypertension:

  • Hypertension 1 degree- systolic pressure 140-159 mm Hg. diastolic pressure 90-99 mm Hg Light form a disease in which an abrupt change in blood pressure is characteristic can either independently return to normal 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 drops.
  • Hypertension 3 degrees- systolic above 180 mm Hg. diastolic above 110 mm Hg Severe form, pressure is consistently at the level of pathological indicators, proceeds with severe complications, it is difficult to correct with medications.

Separately isolated systolic hypertension 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, ischemic 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.

Useful information

It is worth noting another insignificant group - the so-called "white coat hypertension", when, under the influence of psycho-emotional factors, a person's blood pressure rises only when it is measured by a medical professional. In such cases, the diagnosis is clarified by repeated blood pressure measurements in a calm home environment.

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

  • Transistor ( initial stage) hypertension... The increase in pressure is periodic, returning to normal values; drugs that reduce blood pressure are not used.
  • Labile hypertension... An increase in blood pressure is directly related to a provoking factor: stress, severe psychological or physical stress. To stabilize the pressure, medication is needed.
  • Stable arterial hypertension... A persistent increase in pressure, in which serious supportive therapy is used.
  • Malignant form... Increasing pressure to very high levels, the disease progresses rapidly and leads to the development of serious complications.
  • Crisis form... Periodic hypertensive crises are characteristic against the background of normal or slightly increased blood pressure.

Assessment of the severity of hypertension and risk possible complications is possible only on the basis of a thorough examination: general and biochemical analyzes, Ultrasound of the heart and other organs, ECG, examination of the fundus. A complete examination of a patient with arterial hypertension is usually carried out during inpatient treatment.

High blood pressure is the main alarming symptom of hypertension in both men and women

Symptoms of hypertension may be absent for a long time, and if a person does not constantly use a tonometer, 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, because in a number of situations (stress, fear or anger) pressure can increase, and then independently return to normal. However, few control their blood pressure, so you should pay attention to the following symptoms, indicating the development of arterial hypertension:

  • Headache. Most often it manifests itself in the occipital, parietal region or in the temples. It can occur both at night and immediately after waking up. As a rule, it is aggravated by mental or physical activity... Sometimes it is accompanied by swelling of the eyelids and face.
  • Dizziness. Sometimes even with a little physical effort: coughing, turning or tilting the head, a sharp rise.
  • Pain in the region of the heart. They arise not only during emotional stress, but also at rest. Both prolonged aching, squeezing pains and short-term, stabbing pains are possible. Do not disappear after taking nitroglycerin.
  • Strong heartbeat.
  • Noise in ears.
  • Visual impairment: veil, fog, "flies" before the eyes.
  • Arterial involvement: cold limbs, intermittent claudication.
  • Swelling of the legs. Indicate impaired renal excretory function or heart failure.
  • Dyspnea. It occurs both during physical exertion and at rest.

It's important to know

A hypertensive crisis is an emergency caused by an excessively high level of blood pressure; it can also be classified as symptoms of grade 2 and 3 hypertension. At the same time, patients with grade 1 arterial hypertension, strictly following the doctor's recommendations and following a diet for hypertensive patients, can achieve complete disappearance of the unpleasant symptoms of the disease.

This is not to say that the symptoms of hypertension in men and women differ significantly, but in fact, men are really more susceptible to this disease, especially when it comes to age group from 40 to 55 years old. This is partly due to the difference in physiological structure: men, unlike women, have a greater body weight, respectively, and 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, correct lifestyle. The number of stressful situations at work, alcohol consumption and smoked cigarettes is greater in men, but this no longer refers to the symptoms of hypertension, but to the reasons for its development.

Treatment of hypertension with medication and folk remedies

Treatment of hypertension, as well as other diseases that are difficult to diagnose and require constant therapy ( diabetes, allergy, prostatitis and impotence), should be drawn up and prescribed only by a specialist. If restrictions on food, use table salt, quitting alcohol and smoking, avoiding stress and other corrected causes of hypertension does not help to normalize the level of blood pressure, pills from high pressure.

Methods for treating hypertension

In the treatment of hypertension folk remedies side effects are usually absent. You do not have to run to the pharmacy for expensive drugs and stand in line for the doctor to write 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; in the development of the disease, an important role is played by both internal systems organism, and external factors. If, in symptomatic hypertension, the causes of an increase in blood pressure are caused by other diseases, then in essential hypertension, and this form is recorded in 85% of cases, it is not possible to establish the exact reasons for high blood pressure, it arises on its own.

There are many risk factors that contribute to a persistent increase in blood pressure, it is these factors that are considered to be the causes of hypertension. These include:

  • Age, men over 55 years old, women over 65 years old. With age, the walls of blood vessels lose elasticity, which increases their resistance to blood flow, as a result, the pressure rises.
  • Hereditary predisposition.
  • Floor. As already mentioned, men are more likely to suffer from arterial hypertension.
  • Violation of fat metabolism, obesity (men with a waist volume of more than 102 cm, women - more than 88 cm).
  • Diabetes.
  • Smoking. It 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 quits drinking is reduced by at least fifteen points.
  • Excessive salt intake. Excessive intake of sodium, the main constituent of table salt, is one of the most significant reasons for an increase in 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, on average, a person consumes three times the amount of salt that he needs, learn not to add salt to food.
  • Insufficient physical activity, sedentary lifestyle.
  • Exposure to stress.
  • Violation of cholesterol metabolism.
  • Insufficient intake of potassium with food.
  • Increased level of adrenaline in the blood.
  • Congenital heart defects.

Various kidney diseases, late toxicosis of pregnant women, regular intake 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 on their own or with the help of doctors: to treat obesity, reduce blood cholesterol levels, the number of cigarettes smoked, alcohol or salt consumed, lose weight, and so on.
  • There is no way to avoid: age and hereditary predisposition.

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

Complaints: headache, more often in the occipital and parietal regions, heaviness in the back of the head, dizziness, noise in the head, "flying flies" before the eyes, stabbing or aching pains in the precordial region.

Examination and palpation: often hypersthenic constitution, increased nutrition, facial flushing. The apical impulse is diffuse, resistant, displaced to the left, sometimes downward. The pulse is firm, full.

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

Auscultation: I tone at the apex is weakened, accent of tone II above the aorta. As the changes from the left ventricle increase, a functional systolic murmur at the apex of the heart, heart rhythm disturbances may appear.

Instrumental research methods

X-ray: Signs of left ventricular hypertrophy, aortic configuration of the heart, the aorta is enlarged, 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 can be flattened, smoothed or even negative T in I, aVL, V 5-6.

Ocular fundus: retinal arteries are narrowed, twisted, veins are dilated. Symptoms of Guna-Salus I, II, III Art. 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 the level of blood pressure, is not associated with any independent damage to organs and systems. 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 currently not used.

Etiology and pathogenesis

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

    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 into the body);

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

    traumatic brain injury;

    intoxication (smoking, alcohol);

    violation of fat metabolism (obesity);

    hypodynamia.

The factors determining the prognosis in hypertension (risk stratification criteria) are outlined below.

In the occurrence of EAH, a very large role is played by burdened by heredity ... It is believed that the genetic defect is associated with a defect in plasma membranes and is expressed in impaired transport of monovalent cations and calcium. However, in order for the disease to occur, it is necessary to have predisposing factors (stress, smoking, physical inactivity, etc.) 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 the disruption of normal neurogenic and / or humoral regulation of 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 links in the pathogenesis of hypertension are:

1. Strengthening of 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). The greatest importance is attached to this link.

2. Depletion of depressive factors:

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

    decrease in the production of sodium uretic atrial factor (PNUF);

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

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

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

This is the main pathological condition organism that creates everything the necessary conditions for the development of disorders in the work 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 total value with the term widely used abroad, "essential hypertension" and means an increase in the level of blood pressure above normal for no apparent reason.

Symptoms of pathology

Signs of high blood pressure are often not 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 of arterial hypertension:

GARDEN within normal limits for healthy person should be at the level of 120-129 mm Hg, and normal DBP - 80-84 mm Hg. A systolic pressure of 130 to 139 mm Hg is called highly normal, and a diastolic pressure is 85 to 89 mm Hg. Art.

ICD-10 coding

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 the 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 degree of CVD:

  1. The male sex is more prone to the occurrence of disorders of the heart and blood vessels at the age of over 55;
  2. Cases of arterial hypertension are more common over the age of 65;
  3. Smoking helps to reduce the tone of the vascular walls and increase blood pressure on them;
  4. Violations of the lipid composition of the blood (an increase in the number of low-density lipoproteins and a decrease in the amount of high-density lipoproteins);
  5. Increased blood glucose;
  6. Obese people almost always have hypertension;
  7. Poor family history of heart and vascular disease.

To determine the CCP, 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 EchoS and ECG;
  3. The presence of chronic kidney disease and concomitant microalbuminuria;
  4. The formation of atherosclerotic plaques on the walls of the carotid arteries;
  5. Diabetes;
  6. Vascular pathology of the brain;
  7. Cardiac ischemia;
  8. Pathological changes in the retina.

Blood pressure measurement technique

How to measure blood pressure correctly? Various devices are used to measure blood pressure in the arterial bed. The doctor measures the pressure either nurse... The patient can also take measurements on their own using an automatic blood pressure monitor.

The patient should be in a sitting position, with an arm raised to the level of the heart, in a relaxed state. A few minutes before the measurement, the intake of coffee or tea, sympathomimetics, physical activity is excluded.

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

With the help of a special rubber bulb, air is injected until the pulse on the radial artery is no longer registered. Then air slowly descends. Using a phonendoscope, you need to register Korotkov's tones. When the first tone is heard, the SBP is recorded, and when the last - the DBP level. The measurement is carried out twice. In the future, the pressure is determined on the hand on which the most was recorded.

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

ABPM is a 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 during the day. The device constantly registers changes in blood pressure arterial blood in line. To the patient, recording his actions and the time of taking certain medications during monitoring.

Indications for performing ABPM and SCAD:

  1. Suspicions that the pressure rises at the sight of 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 in its values ​​after several visits to the doctor;
  4. With a decrease in blood pressure during the change from horizontal to vertical (standing);
  5. With a significant drop in blood pressure during sleep in the daytime;
  6. If hypertension is suspected, nocturnal.

By using the sphygmogram and shoulder pressure measurements, central BP can be calculated. To begin with, a collection of complaints and anamnesis of life, disease is carried out. Then the height and body weight are measured in order to calculate the patient's body mass index.

Diagnosis of pathology

  1. Normalization of nutrition. Increasing the amount of food vegetable 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 activity). It is advisable not to engage in power sports;
  5. Weight loss 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 drugs for pressure:

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

    Preparations of this series protect the vascular wall from the imposition of thrombotic masses, prevent the onset 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, metabolic disorders in the body may occur. Most often they are combined with an ACE inhibitor or BAP. Aldosterone receptor antagonists (spironolactone) lower 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, heart failure. 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, prevent the occurrence of strokes.

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

There are other classes of antihypertensive drugs:

  1. Imidazoline receptor agonists (rilmenidine, moxonidine). They have a positive effect on the body's carbohydrate metabolism, contribute to the patient's weight loss;
  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 have the expected effect. There are such rational combinations of drugs: a diuretic and an ACE inhibitor, a diuretic and an ARB, an ACE inhibitor and calcium antagonists, a diuretic and calcium antagonists, ARBs 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 different doses. Aspirin also prevents the formation of atherosclerotic plaques on the walls of blood vessels.

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

Hypertensive crisis treatment

A hypertensive crisis is a sudden onset of an increase in blood pressure above 160/120 mm Hg, accompanied by certain clinical manifestations. Crises are uncomplicated and 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 lower 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;
  • Diuretic drugs;
  • Antipsychotics.

Uncomplicated crisis is stopped faster, oral antihypertensive drugs are used (captopril, clonidine, moxonidine, nifedipine, etc.).

Prophylaxis

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

Treatment of arterial hypertension is selected individually for each individual. The patient's daily regime and diet, the nature of the physique and many other factors are taken into account. Acceptance of drugs 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.

In contact with

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

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

Classification

The most common form is a mixed form, in which both systolic and diastolic pressure increases. Less often, isolated hypertension occurs - an increase in only one of the types of pressure. The last form typical for the elderly.

Due to the occurrence, 2 types of arterial hypertension can be distinguished:

  1. Primary - idiopathic or essential, the cause of which cannot be established. It occurs in 90% of cases. The diagnosis of primary hypertension is established by excluding all possible reasons increase in blood pressure.
  2. Secondary - is only a symptom of any 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 - systolic blood pressure< 120, дАД
  2. Normal - accordingly< 120-129/80-84 мм.рт.ст.
  3. High normal - SBP is in the range of 130-139 mm Hg, and DBP is 85-89 mm Hg.
  • I degree - 140-159 / 90-99 mm Hg
  • II degree - an increase in SBP from 160 to 179 and DBP from 100 to 109 mm Hg.
  • III degree - SBP from 180 and>, DBP> 110 mm Hg.

Classification by stage of the disease:

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

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

Forms of arterial hypertension in accordance with the level of pressure increase:

  • mild hypertension - corresponds to the I degree of increase in blood pressure;
  • moderate hypertension - corresponds to the II degree of increase in blood pressure;
  • severe hypertension - corresponds to the III 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 contributing factors:

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

Hypertension syndrome can occur in the following diseases:

  • glomerulonephritis;
  • vasoconstriction 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;
  • insufficiency of the aortic valve in the heart;
  • post-traumatic encephalopathy;
  • aortic pathology - coarctation or atherosclerosis;
  • Page's disease - damage to the hypothalamus;
  • encephalitis, meningitis;
  • subarachnoid hemorrhage.

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

The mechanism of increasing 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 associated with the vascular system of the body.

BP is determined by three main factors:

  1. The total peripheral vascular resistance - depends on the state of the vascular wall, the degree of narrowing of the vascular lumen.
  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 the theory of central genesis. According to this theory, arterial hypertension occurs due to a violation of the 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. The etiology of arterial hypertension in this case is an inadequate reaction of the hormonal system to psycho-emotional and physical stress. As a result of the increased response of the sympatho-adrenal system, the 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 consists in a change in renin secretion of renin. Under the action of this hormone, angiatensin-1 is formed, which turns into angiatensin-2, which has a vasoconstrictor effect.

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

  • mineralocorticoids (in particular, aldosterone) - retain sodium ions in the body, which leads to fluid retention and an increase in BCC;
  • atrial natriuretic factor - promotes the excretion of sodium from the body, reducing the BCC and blood pressure. With a decrease in the amount of this factor, uncontrolled arterial hypertension occurs;
  • impairment of ion transport through cell membrane- with vascular hypertension, the membrane permeability 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, 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, an increase in heart rate, or an increase in the volume of circulating blood.

Clinical and pathophysiological changes in target organs

Before proceeding to the clinic, it is necessary to understand the following: the totality of the symptoms of the disease and are the concepts of arterial hypertension and essential hypertension identical with each other?

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

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

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

Pathological changes in the vessels concern, first of all, their walls: there is its hypertrophy, proliferation and infiltration with plasma proteins. 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 supplied by them.

Changes in the heart begin with myocardial hypertrophy. In the future, 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 depressive mechanisms are inhibited. Subsequently, structural and degenerative changes occur 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 discirculatory encephalopathy, ischemic and hemorrhagic strokes.

Simply put, high blood pressure leads to a thickening of the vascular wall and an increase in the load on the heart. This causes thickening of the myocardium and the development of heart failure. Other target organs, such as the brain, kidneys, and eyes, also suffer as a result of the deterioration of the blood supply.

Clinical picture

By itself, arterial hypertension has no symptoms. Most patients with this disease do not complain about anything at all, high blood pressure come to light by chance.

The clinical manifestations of arterial hypertension depend on which organs are affected at the moment. Patients with benign arterial hypertension may present with the following complaints:

  • Headache - may be the very first and main symptom. There are several types of headaches:
  1. dull, not 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, aggravated by a sharp change in the position of the head and even minor physical exertion. Such 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. liquor - bursting diffuse throughout the head, may be pulsating. Any tension causes increased pain. It occurs most often in the later stages of hypertension or in the presence of pulse hypertension. As a result of this, the vessels are sharply overfilled with blood and its outflow is difficult;
  3. ischemic - dull or breaking in nature, accompanied by dizziness and nausea. It occurs with a sharp increase in blood pressure. A sharp vasospasm occurs, as a result of which the blood supply to the brain tissues is disrupted.
  • Pain in the region of the heart - cardialgia, not ischemic in nature, the coronary vessels are in order, while the pain does not stop with the sublingual application of nitrates (nitroglycerin under the tongue) and can occur both at rest and with emotional stress... Sports activities are not a provoking factor.
  • Shortness of breath - at first occurs only when playing sports, with the progression of hypertension, it can also occur at rest. Characterizes the violation of the heart.
  • Swelling - most often found on the legs due to stagnation of blood in big circle circulation, sodium and water retention, or renal impairment. The appearance in children simultaneously with edema of hematuria and hypertension is characteristic of glomerulonephritis, which is very important to remember when conducting a differential diagnosis.
  • Visual impairment - manifests itself in the form of blurred vision, the appearance of a veil or flashing flies. It occurs due to damage to the retinal vessels.

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

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

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 thorough survey.

It should also be remembered that hypertension in adolescents is much less common than in the elderly.

The main sign of hypertension, which a doctor can detect during an examination, is an increase above 140/90 mm Hg. Art. Signs of hypertension on examination can be very different: from edema to lower limbs to cyanosis of the skin. They all characterize ischemia and hypoxia. internal organs.

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

The definition of arterial hypertension sounded the specific figures of the increase in pressure, and therefore the formulation of the diagnosis is possible only when these figures are established in two dimensions within a few days. Patients with arterial hypertension most often require daily monitoring of blood pressure.

Hypertensive crisis

A hypertensive crisis is an urgent condition consisting in 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 death is possible.

To provide emergency the patient is required to be immediately taken to the hospital, where he is quickly lowered blood pressure with medications.

Medical students study first aid for hypertensive crisis at the Department of Propedeutics of Internal Medicine, and therefore it would be best for a bystander not to try to help, but to call an ambulance.

High blood pressure treatment

Many people wonder how to treat 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 in reducing and eliminating the following risk factors:

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

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

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

The principles of hypertension treatment are as follows:

  1. Treatment should start 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 priority 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, proceed to a combination of drugs of 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 the elderly, when treating hypertension, it is recommended to start with slow calcium channel blockers. Components that alter the metabolism of glucose and insulin should be avoided in the formulations of preparations. The main goal of treatment in the elderly is to prevent fatal complications.

When formulating the diagnosis of arterial hypertension, all the features of the course and the presence of complications should be most fully characterized in order to determine the most correct tactics for treating 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, the leading symptom in which is a persistent increase in blood pressure above 140/90 mm. rt. article e in persons not receiving antihypertensive therapy

By etiology, it is divided:

1. Essential or primary arterial hypertension (hypertension).

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

n Essential hypertension is a disease of the cardiovascular system that develops as a result of primary dysfunction (neurosis) of the 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... It accounts for up to 95% of all cases of chronic high blood pressure.

n The reasons for the formation of essential hypertension are not precisely established. It is believed that it develops with a combination of a hereditary predisposition to the disease and adverse effects external factors(stress, excessive consumption of table salt, low 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, an increase in cardiac output, or a combination of these factors. An important role in this process is played by the activation of the sympathoadrenal and reninagiotensin systems.

CLASSIFICATION OF HYPERTONIC DISEASE

By stage

Stage I there is no change in target organs.

Stage II - there is damage to target organs (LV myocardial hypertrophy, retinal angiopathy, moderate proteinuria).

Stage III the presence of one or more accompanying

(associated) clinical conditions:

Consequences of ONMK;

Hypertensive retinopathy (hemorrhages and

exudates, swelling of the nipple of the optic nerve);

Creatinemia (more than 2.0 mg / dL);

Aortic dissecting aneurysm.

By the degree of increase in blood pressure.

IAD degree 140-159 / 90-99 mm Hg

IIAD degree 160-179 / 100-109 mm Hg

Grade IIIAD 180/110 mm Hg and higher

n Isolated systolic hypertension - systolic blood pressure> 140 mm Hg and diastolic<90 мм.рт.ст.

n Malignant hypertension - diastolic blood pressure more than 110 mm Hg and the presence of pronounced changes in the fundus (retinal hemorrhage, edema of the optic nerve

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

GB RISK FACTORS:

1. Men over 55;

2. Women over 65;

3. Smoking;

4. Cholesterol> 6.5 mmol / L;

5. Heredity (for women under 65;

6. for men under 55);

7. Diabetes mellitus.

8. Abdominal obesity (waist over 102 cm in men, over 88 cm in women)

Target organ damage:

1. Hypertrophy of the left ventricle;

2. Narrowing of retinal vessels;

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

4. Atherosclerotic changes in the arteries.

Concomitant diseases or complications of hypertension:

n heart: HF, angina pectoris, MI;

n brain: violations cerebral circulation;

n ocular fundus: hemorrhages and exudates in the retina, edema | of the nipples of the optic nerves;

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

n vessels: aortic dissection, occlusive arterial disease;

n diabetes mellitus

Syndromes in hypertension

1. Syndrome of arterial hypertension.

Clinical manifestations :

HELL more than 139/90 mm Hg. Art .;

on examination, you can notice pallor or flushing of the face;

the pulse is usually symmetrical, hard, high and fast;

with percussion, expansion of the vascular bundle;

on auscultation: accent II tone over the aorta,

On ECHO-KS, the aortic dilatation is> 40mm.

2. Target Organ Damage Syndrome:

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

· Kidney (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 the vessels of the brain. Initial signs headache, dizziness, tinnitus, decreased memory, mental performance.

Fundus changes

I degree- segmental or diffuse changes in arteries and arterioles.

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

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

IV degree- the same + bilateral edema of the nipple of the optic nerve, blurred edges, retinal detachment, star symptom.

COMPLICATIONS OF HYPERTONIC DISEASE:

Left ventricular failure; with a combination of hypertension and ischemic heart disease - an increase in the frequency of angina attacks; the likelihood of myocardial infarction is high; dissection of the aortic aneurysm; cerebral or cerebellar hemorrhage, hypertensive encephalopathy, cerebral artery thrombosis; retinal hemorrhages and exudates with and without papilla of the optic nerve edema; decreased renal blood flow and glomerular filtration rates, mild 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 the cerebral, coronary and renal circulation of varying severity).

Clinical manifestations :

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

2. Individually high blood pressure

3. Complaints of a cardiac nature (palpitations, interruptions and pain in the region of the heart, shortness of breath)

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

5. Complaints of a general neurotic nature (chills, tremors, feeling of heat, sweating).

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

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

CORONARY INSUFFICIENCY SYNDROME

Essence: the syndrome is caused by a discrepancy between myocardial oxygen demand 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 the coronary blood flow, which can decrease in both organic and functional disorders in the coronary arteries.

Main reasons :

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

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. Coronaries.

6. Cardiomyopathy.

Cardiac ischemia

IHD is an acute and chronic heart disease caused by a decrease or cessation of blood delivery 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 pectoris:

Stable (4 functional classes)

Unstable (first-emerging, progressive, spontaneous, resting, early postinfarction)

3. Myocardial infarction (with Q and without Q)

4. Postinfarction cardiosclerosis.
