Coronary heart disease: symptoms and treatment

Coronary heart disease – an acute or chronic lesion of the myocardium, resulting from a reduction or interruption of the supply of arterial blood to the heart muscle, based on pathological processes in the coronary artery system.

It is a widespread disease. One of the main causes of death, temporary and permanent disability around the world. In the structure of mortality, cardiovascular diseases take first place, of which ischemic heart disease accounts for about 40%. If you have this problem, you can buy medicines here

The main etiological factor in the development of coronary artery disease is atherosclerosis. Atherosclerosis develops consistently, wavy and steadily. As a result of the accumulation of cholesterol in the artery wall, an atherosclerotic plaque is formed. Excess cholesterol leads to an increase in the size of the plaque, there are obstacles to the blood flow. Further, under the influence of systemic unfavorable factors, the transformation of the plaque from stable to unstable occurs (there are cracks and ruptures). The mechanism of platelets activation and thrombosis formation on the surface of an unstable plaque is started. Symptoms are exacerbated with the growth of atherosclerotic plaque, gradually narrowing the lumen of the artery. Decrease in the area of arterial lumen by more than 90-95% is critical, causing a decrease in coronary blood flow and deterioration of health even at rest.

Classical manifestations of coronary heart disease

  1. Pain behind the sternum, often irradiates into the lower jaw, neck, left shoulder, forearm, hand, back.
  2. The pain is pressing, squeezing, burning, strangling. The intensity is different.
  3. Provoked by physical or emotional factors. At rest they stop on their own.
  4. Lasts from 30 seconds to 5-15 minutes.
  5. Quick effect of nitroglycerin.

Treatment of ischemic heart disease

Treatment is aimed at restoring normal myocardial blood supply and improving the quality of life of patients. Unfortunately, purely therapeutic methods of treatment are not always effective. There are many surgical methods of correction, such as: aortic coronary bypass, transmyocardial laser revascularization of the myocardium and percutaneous coronary interventions (balloon angioplasty, coronary artery stenting).

Selective coronarography is considered the “golden standard” in the diagnosis of obstructive coronary artery lesions. It is used to find out if the vascular contraction is significant, which arteries and how many of them are affected, in what place and in what course. Recently, multispiral computed tomography with intravenous bolus contrast has become more and more common. In contrast to selective coronarography, which is essentially an arterial X-ray surgery, and is performed only in an inpatient setting, multi helical computed tomography of coronary arteries is usually performed on an outpatient basis with intravenous injection of a contrast agent.

Aortocoronary bypass is an operation, which has been practiced for many years, when a patient takes his own vessel and sutures it to the coronary artery. Thus, a way is created to bypass the affected section of the artery. Blood normally enters the myocardium, which leads to the elimination of ischemia and the disappearance of angina attacks. Aortocoronary bypass is a method of choice for a number of pathological conditions such as diabetes mellitus, trunk lesion, multi vascular lesion, etc.
