Coronary heart disease (CHD) is a disease that combines angina, myocardial infarction and atherosclerotic cardiosclerosis. Coronary artery disease develops due to insufficient blood supply to the coronary arteries of the heart due to narrowing of the lumen.
what causes coronary heart disease?
With age along the inner lining of the coronary arteries appear deposits of fatty substances such as cholesterol. These fatty deposits called atherosclerotic plaques. Over time, they grow, narrowing the artery and restricting blood flow to the heart muscle. In the end, atherosclerotic plaques impede blood flow to the heart muscle, what we signaled chest pain-angina. So developing coronary heart disease.
Signs of coronary heart disease
ischemic heart disease develop signs of cardiac abnormalities — pain attacks in the heart, interruptions in heart rate, there have been changes on the electrocardiogram.
you Need to keep in mind that CHD is a disease that progresses very slowly. And it is very important to detect the disease at early stages of development.
an Important diagnostic sign of coronary heart disease is a feeling of discomfort in the chest or back that occurs during a walk, some physical or emotional stress and extending after the termination of this burden. The characteristic symptom of angina pectoris is also the rapid disappearance of discomfort after taking nitroglycerin (10-15 seconds).
In recent years, an increasing number of cases of sudden death in patients with coronary artery disease. The defeat of the arteries supplying the heart, leading to stenosis and obstruction; as a result of impaired blood supply to the heart muscle.
That contributes to the development of coronary heart disease?the
How to establish the diagnosis of ischemic heart disease?
For an accurate diagnosis, it is primarily necessary to consult a qualified cardiologist.
Your doctor will carefully examine the causes and development of disease, prescribe the research necessary to confirm the diagnosis.
the Final stage of diagnosis is coronary angiography. This is the most accurate modern method, which allows to determine the number and size of atherosclerotic plaques, and their location in the blood vessels of the heart.
