Types of hypertension
The terms “hypertension” and “hypertension” can be considered identical.
The difference between them is that hypertension is a diagnosis (disease), and hypertension is the very fact of high blood pressure (more than 140/90 mm Hg). Hypertension is said to occur when high blood pressure is not an occasional phenomenon, but bothers a person regularly. There are several classifications of hypertension. Based on their origin, there are 2 main types - primary and secondary hypertension.
Primary hypertension
It is also called essential or idiopathic (of unclear origin). According to statistics, up to 90% of people with high blood pressure have essential hypertension. Medicine is not able to determine the true causes of such hypertension, so patients are offered symptomatic treatment - constantly measure blood pressure and take medications to reduce it (if necessary).
Risk factors for primary hypertension include:
- Hereditary predisposition - the presence among direct relatives of hypertension and people suffering from cardiovascular diseases. Currently, more than 50 genes are known that may be associated with high blood pressure³.
- Smoking. In smokers, blood vessels constantly spasm (narrow). This increases the risk of developing cardiovascular diseases, including hypertension.
- Age and gender. The likelihood of developing essential hypertension increases with age. The majority of patients with arterial hypertension are people over 55 years of age. Men are more likely to worry about high blood pressure than women.
- Obesity. This is one of the significant factors in the development of hypertension. It has been found that obese people are 5 times more likely to develop hypertension than people of normal weight. Epidemiological studies show that more than 60% of people with hypertension are also overweight⁴. And 85% of hypertensive patients have a body mass index above 25⁴.
What is body mass index
Body mass index (BMI) is a value that allows you to estimate the ratio of a person’s weight to his height. Calculating BMI is very simple. To do this, you need to divide your body weight in kg by the square of your height in meters (I=m/h²). For example, if your height is 1 meter and 82 cm, and your weight is 82 kg, then BMI = 82/1.82² = 24.76. A BMI of 18.5 to 25 is considered normal. From 25 to 30 is overweight (pre-obesity); from 30 to 35 - 1st degree obesity; 35-40 - second degree; more than 40 – 3rd degree obesity.
Other factors contributing to the development of hypertension include low physical activity, alcohol abuse, and certain diseases (for example, diabetes).

Secondary hypertension
This is a type of hypertension that occurs due to a primary disease. It accounts for 5-10% of cases. The most common causes of secondary arterial hypertension are:
- Renal diseases - glomerulonephritis, renal artery damage, pyelonephritis, polycystic kidney disease and other diseases.
- Endocrine disorders - diseases of the adrenal glands and thyroid glands.
- Diseases of the central nervous system - tumors of the brain and spinal cord, intracranial pressure, strokes, brain injuries and other diseases.
- Cardiovascular pathologies - congenital heart defects, atherosclerosis, dysfunction of the heart valves and other diseases.
- Drug-induced hypertension is an increase in blood pressure associated with taking medications. For example, some patients may experience increased blood pressure after taking nonsteroidal anti-inflammatory drugs, glucocorticoids, or catecholamines.
- The effect of toxic substances - alcohol, heavy metals and others.
Hypertension (primary and secondary) is also classified according to blood pressure level.
This classification is given in Table 1. Table 1. Degrees of arterial hypertension
Category | Systolic pressure (mmHg) | Diastolic pressure (mmHg) |
Optimal | up to 120 | up to 80 |
Normal | 120-129 | 80-84 |
High normal | 130-139 | 85-89 |
Hypertension 1st degree | 140-159 | 90-99 |
Hypertension 2 degrees | 160-179 | 100-109 |
Hypertension 3 degrees | more than 180 | more than 110 |
Doctors recommend paying attention to blood pressure already at the stage when it exceeds 120 mmHg. Art. This blood pressure is considered normal and you do not need to take any antihypertensive drugs, but it is advisable to have an annual check-up with your doctor. As for hypertension, at different stages they resort to different treatment strategies:
- In the first stage, serious medical interventions are not needed. The patient is recommended to adhere to a healthy lifestyle and regularly measure blood pressure. If necessary, take medications for high blood pressure (the list of the best medications will be discussed below).
- At the second stage, mandatory drug correction is necessary. The doctor prescribes one or another type of drug (if necessary, the drugs are changed to more effective ones).
- At the third stage, in addition to pressure correction, treatment of concomitant diseases (cardiovascular, renal, endocrine and others) is also necessary.

Symptoms of high blood pressure
Symptoms of high blood pressure are nonspecific. These include:
- headache;
- dizziness;
- noise in ears;
- weakness;
- sleep disorder
With secondary hypertension, the symptoms described above may be accompanied by lower back pain, difficulty urinating, and swelling (due to problems with the kidneys and/or heart).
Hypertensive crisis and its symptoms
A sudden significant increase in blood pressure is called a hypertensive crisis.
There are no clear criteria for a hypertensive crisis, but most literature sources indicate that this is a sharp increase in systolic blood pressure by 40 mmHg. Art. and more. The following symptoms are characteristic of a hypertensive crisis:
- a sharp deterioration in health;
- Strong headache;
- chest pain;
- vomit;
- convulsions;
- chills and sweating;
- nose bleed;
- shortness of breath and suffocation;
- skin redness;
- disturbance of consciousness;
- paresis and paralysis;
- stroke.
This is a serious condition that can lead to death. It is necessary to immediately call an ambulance, and before the medical team arrives, lay the victim down or sit comfortably. Place a pillow or folded blanket under your shoulders and head. This will help avoid an attack of suffocation. It is necessary to unfasten tight-fitting clothing and open the window, providing the person with access to fresh air.
Veroshpiron
This medicine helps the body remove excess fluid, eliminating swelling. Potassium in Veroshpiron improves the functioning of the heart and blood vessels, and many patients note that the drug relieves seizures.

Classification of drugs for high blood pressure
Medicines for high blood pressure are called antihypertensives (or hypotensives). The pathogenesis of hypertension has now been studied quite well (despite the lack of knowledge about the cause of hypertension). This allowed scientists to create drugs for high blood pressure with different mechanisms of action.
The availability of a relatively large selection of antihypertensive drugs greatly facilitates the work of doctors. For example, if the patient is not helped by drugs with one mechanism of action, then a decision is made to prescribe other drugs (which act on other pathogenetic links of the disease). Below we will look in more detail at the main groups of antihypertensive drugs.

Diuretics (diuretics)
These are drugs that inhibit the reabsorption of water in the kidneys, which increases the rate of its excretion. In this way, it is possible to reduce the water level in tissues and cavities (swelling is relieved).
The antihypertensive effect of diuretic drugs is the forced removal of sodium salts and water from the body. This significantly reduces the load on the vessels, which leads to a decrease in pressure.
In addition to sodium, most diuretics also remove potassium from the body, which is necessary for normal heart function. Therefore, potassium supplements are often prescribed along with diuretics. There is also a special class of diuretics - potassium-sparing diuretics.
Adrenergic blockers
Adrenergic blockers are substances that block receptors for adrenaline and norepinephrine. There are alpha-adrenergic receptors (located in arterioles) and beta-adrenergic receptors (localized in the heart, kidneys, bronchioles and other tissues). Accordingly, alpha and beta adrenergic blockers are distinguished. The former reduce blood pressure by reducing arteriolar spasm. The second - reduce cardiac output and slow down the heart rate, thereby reducing blood pressure.
Angiotensin-converting enzyme (ACE) inhibitors
Drugs in this group promote dilation of arterioles by inhibiting ACE activity. The latter is an enzyme that converts angiotensin I into angiotensin II, a substance that has the effect of constricting arterioles. Inhibition of ACE activity reduces the concentration of angiotensin II, which leads to a decrease in blood pressure⁵.
ACE inhibitors have been shown to be particularly effective in cases of coronary heart disease, heart failure, and renal dysfunction (in particular, those caused by diabetes mellitus).
Calcium channel blockers
This is a group of drugs whose active ingredients inhibit the penetration of calcium from the intercellular space into the cells of the heart and blood vessels⁶. Lower calcium concentrations in muscle and vascular cells cause blood vessels to relax and dilate, which lowers blood pressure.
Blood pressure medications: a racial perspective
Clinical trials of drugs are usually carried out in different countries and continents. This is due to the fact that some drugs act differently on representatives of different races. Blood pressure medications are no exception. Thus, ACE inhibitors are ineffective for black patients. In addition, these medications often cause angioedema (swelling of the limbs, face, and mouth). But calcium channel blockers are especially effective among blacks.
Angiotensin II receptor blockers
These drugs have the same effect as ACE inhibitors. But if the latter inhibit the activity of the enzyme that is needed for the production of angiotensin II, then blockers of its receptors do not allow angiotensin II to realize its functions (narrowing of arterioles).

Vasodilators
Vasodilators are drugs that dilate blood vessels through mechanisms other than those described above. Such drugs are rarely prescribed for hypertension. In addition, they are almost never used as monotherapy. As a rule, such medications are recommended as additional to the main blood pressure medication.
FAQ on hypertension treatment: answers to 10 common questions
1. Where should you start treating arterial hypertension?
By eliminating negative factors. Start a healthy lifestyle as soon as possible. It is important to normalize weight, stop smoking and drinking alcohol. Daily walks and other types of physical activity (not strenuous!) will improve your well-being. Be sure to consult a doctor and see a specialist regularly.
2. When should you start taking pills?
This is determined by the doctor. Much depends on the current level of pressure, concomitant diseases and the age of the patient. In most cases, they resort to pills if high blood pressure lasts longer than 2-3 weeks, and the doctor’s recommendations for a healthy lifestyle do not bring the desired results.
3. At what blood pressure should you take medications?
Everything is individual. In most cases it is 140/90 or higher. The main goal of such treatment is to provide the patient with a safe level of pressure, which significantly reduces the likelihood of developing crises.
4. How is the drug group for treatment selected?
This is done by the doctor after diagnosis. For example, if a lot of fluid accumulates in the body, then diuretics are prescribed. If the problem is in narrow vessels, then they can be dilated with calcium antagonists, ACE inhibitors or AT receptor blockers.
5. How do you know what dose of the drug to take?
As a rule, treatment begins with minimal doses. In this case, the patient needs to monitor his condition for several days, it is advisable to record pressure readings in a diary. Then, depending on the data obtained, the doctor decides whether to increase the dose of the medicine to achieve an acceptable level of pressure.
6. What to do if the medicine does not help?
It happens that the dose of the drug has already been increased to the maximum, but there is almost no effect. Don't be upset. The doctor will stop the drug and prescribe another one. The second option is to reduce the dose of the current medication and add another (combination treatment with several drugs).
7. How long does it take to select a treatment regimen?
It all depends on how the body reacts to antihypertensive drugs. In some patients, blood pressure decreases to the desired levels immediately. Others take time to find the right combination of medications.
8. Is it possible to quickly reduce blood pressure?
This is not recommended, especially if we are talking about a systematic (gradual) decrease in pressure. Patients who have lived with high blood pressure for years often consult a doctor. A sharp decrease in blood pressure in this case can significantly worsen their well-being. A rapid decrease in pressure may be justified in case of a hypertensive crisis. But even here the decision on treatment tactics is made by the doctor.
9. What happens if you stop taking the pills?
Arterial hypertension is a chronic disease that requires constant monitoring. If you stop taking the medication, your blood pressure will rise again. The risk of crises and other complications associated with hypertension will increase.
10. What side effects do antihypertensive drugs have?
Very different. This depends on the specific drug. The list of possible adverse reactions (and the frequency of their occurrence) is always indicated in the instructions. Read it carefully, even if your doctor prescribed this drug to you. If any undesirable reaction occurs, contact your doctor.
Calcium antagonists
By blocking the penetration of calcium ions into cells, these drugs cause a reflex relaxation of the muscle walls of blood vessels, reducing their tone. As a result of the expansion of the lumen of the arteries, the blood pressure decreases. Side effects of such drugs include: tachycardia, heart rhythm disturbances, dizziness. Popular tablets of this group:
- Dialtiazem;
- Verapamil;
- Norvasc.
The drugs effectively reduce blood pressure in various forms of hypertension, but do not combine well with other groups of antihypertensive drugs and have many contraindications.
