Stable angina is developed on the background of ischemic heart disease and is the most common manifestation. The main symptom of stable angina are acute sudden pain in the heart Pain in the heart - always consult a doctor Which first appeared on the background of physical exertion and then at rest.

Stable angina - Causes of

The term 'angina' or angina refers to an acute attack of pain in the heart, due to a lack of oxygen in the heart muscle (myocardium). Seizures occur in reducing coronary lumen - blood vessels through which the blood cells in the myocardium receives nutrients and oxygen. It believed that the first heart pain in humans occurs when one or more of the lumen of the coronary arteries is reduced at least by half.

This disease has been called ischemic heart disease - coronary artery disease. In CHD on the walls of the coronary vessels delayed cholesterol plaques, decreasing their clearance. During exercise myocardial oxygen demand increases, which leads to the development of pain attacks .. Stable angina is a clear link to physical activity. The smaller lumen of the blood vessel, the less load on the body causes oxygen starvation of the myocardium, and the greater its degree of functional disorders.

Classification of stable angina

Depending on the degree of deficiency of blood supply to the heart and exercise tolerance stable angina is divided into four functional class (FC):

• FC I - a familiar operation not reduced, angina occur when loads are much higher than usual, for example, long-term running, lifting weights; this angina can be detected during the stress tests for certain categories of professions;
• FC II - a familiar operation not reduced, angina occur when loads are slightly higher than usual, for example, fast climbing stairs, brisk walking or jogging; the degree of stress in this case depends on the fitness of man;
• FC III - decreased physical activity due to the fact that the angina can occur with normal physical activities such as climbing stairs leisurely on one floor, walking and so on;
• FC IV - angina occur at rest or with minor physical activity, such as walking on foot at a slow pace over short distances.

As shown stable angina

Angina is manifested in the form of attacks of acute pain (anginal pain) compressing or pressing nature behind the breastbone. Pain may enroll in the left shoulder, left arm, left side of the neck and face. Sometimes the pain can radiate to the right side of the chest, often under the right shoulder blade. In rare cases the pain can not be felt in the sternum and the heart, the stomach, giving the lower limbs.

The onset of pain is usually sudden, however, in stable angina, it is always associated with physical exertion. The pain gradually increases, keeps a few minutes and then disappears. Characteristically quickly, within two or three minutes after the removal of anginal pain making nitroglycerin.

In some patients, the pain instead of angina manifested feeling of heaviness in the heart, or compression of chest tightness, shortness of breath.

Stable angina occurs chronically. The attacks may be rare or frequent, but long for angina attack Angina - oxygen deficiency May result in a myocardial infarction Myocardial infarction - the most formidable diagnosis . In patients suffering from angina for a long time, developing cardio, heart rhythm is disturbed, symptoms of heart failure.

Treatment of stable angina

First of all, the patient must learn to shoot angina. To do this, you should immediately stop work, take semi-sitting position, open the window or the window to breathe fresh air. Under the language should be as early as possible to take a nitroglycerin tablet.

In order to prevent the progression of stable angina, the patient should always follow a diet (excludes all cholesterol-rich foods, especially fatty foods of animal origin) and lifestyle changes, reducing physical stress.

Drug treatment of stable angina is to prevent angina attacks. For this purpose, prescribe drugs from the group of beta-blockers (atenolol, metoprolol, bisaprolol - inhibit the action of the sympathetic nervous system, which stimulates the secretion of adrenaline - a substance that transforms the body into a state of alert with an increase in oxygen consumption), nitrates (nitroglycerin, isosorbide dinitrate, isosorbide mononitrate - relieves spasms of the coronary arteries), calcium antagonists (verapamil, diltiazem - reduce myocardial oxygen demand).

To prevent the formation of blood clots in the coronary vessels are assigned low-dose aspirin long courses.

Stable angina requires constant medical supervision.

Egilok - for the treatment of cardiovascular diseases. However, this drug has a complex mechanism of action, so it can not be used independently without a doctor's prescription. Your doctor will also choose an individual dose of the drug.

Cordial egilok

Egilok used in various diseases of the cardiovascular system. Many patients want to know how valid a particular medicine, but the instructions difficult to understand something, because they are not written for patients and for doctors. Try to understand what kind of medicine - egilok and how it acts on the diseased heart.

Egilok - a drug that prevents the action of adrenaline on the heart. Adrenaline - a substance that is released during stress. Everyone knows that if a person faces any danger, the heart starts beating very strongly - this is the effect of adrenaline. At the same time narrows blood vessels and raises blood pressure - so our body comes in the "alert" to "repel the enemy" or to escape. Today, there is no need to run from the enemy, but our body continues to operate under the old program, just as it worked when people hunted mammoths. It contributes to the development of various diseases of the heart and blood vessels.

Egilok intercepts the adrenaline in the place of his approach to the nerve endings (receptors), which transmits nerve impulses team. Nerve receptors sensitive to adrenaline, and located in the heart called the beta1-adrenergic receptors, so egilok called beta1-adrenergic blocker.

Under the influence of egilok dilates blood vessels that feed the heart muscle (coronary arteries), heart muscle work more calmly and correctly, less need for oxygen. The conductivity of nerve impulses on the cardiac conduction system is reduced - this reduces cardiac arrhythmias. Blood pressure (BP) is reduced due to the fact that reduced blood ejection volume during each heart beat, and also by reducing the synthesis of substances that enhance AD.

Do egilok side effects

Like any effective drug egilok has side effects. The problem is that completely separate the effects of the drug on the heart just does not work in some cases, it inhibits the action of adrenaline and other organs, which manifests itself in the form of side effects.

In other internal organs sensitive to adrenaline receptors called beta2-adrenergic receptors and blocking the transmission of adrenaline they can adversely affect the patient. For example, epinephrine, promotes the expansion of the bronchi, which means it can cause lock bronchospasm, especially in patients with bronchial asthma or asthmatic bronchitis.

Epinephrine also causes relaxation of smooth muscles of the gastrointestinal tract and its absence can cause spasm of the muscles, resulting in side effects such as nausea, vomiting, diarrhea, dry mouth.

Adrenaline contributes to the rapid absorption of glucose Glucose: The energy source So lock it can cause various side effects in patients with diabetes.

Adrenaline tones the central nervous system and in its absence may cause lethargy, depression Depression - a little more than a bad mood , Anxiety, decreased concentration.

Finally, if on their own, without a doctor's prescription to take egilok cardiovascular diseases, it can cause a sharp decrease in blood pressure, increased signs of cardiovascular disease, various heart rhythm disorders. It is therefore important to consider the appointment of egilok all the indications and contraindications for its reception.

Indications and Contraindications

Egilok indicated for coronary artery disease - angina Angina - the consequences of the activity   and rest myocardial infarction. Assign it as at various cardiac arrhythmias, high blood pressure and elevated thyroid function, which is accompanied by disorders of the cardiovascular system.

Contraindications egilok low blood pressure, a very slow heart rate (bradycardia with a heart rate less than fifty per minute), when expressed violations of the conductivity of nerve impulses on the cardiac conduction system (heart block degree II-III), prolonged severe attacks of angina (angina Prinzmetal ), heart failure decompensation (heart can not cope with the load), while feeding the baby Breastfeeding - a personal choice   breast and are hypersensitive to this drug.

With caution it is administered during pregnancy, at the heart of the blockade in the initial stages, in violation of liver and kidney function.
