Atherosclerosis of the coronary arteries of the heart - it isthe main cause of coronary heart disease, arising from the violation of the blood supply to the heart muscle. Such forms of coronary heart disease as angina or myocardial infarction is completely determined by the degree of atherosclerosis of the arteries of the heart: a partial blockage of the blood vessels of the heart manifests itself in the form of coronary disease of varying severity, and the complete blockage of heart vessels leads to the development of myocardial infarction. In this article, we describe the main symptoms and signs of coronary atherosclerosis (coronary) arteries of the heart.
Atherosclerosis of the coronary arteries of the heart
heart blood supply is provided by twocoronary arteries extending from the beginning of the aorta (the central blood vessel of the body). Any violation of the circulation of the blood by the coronary (coronary) arteries of the heart leads to disruption of the heart muscle and can be the cause of heart attack (necrosis of the heart muscle).
The most common cause of circulation disordersBlood on the coronary heart is atherosclerosis of the arteries. Atherosclerosis is characterized by the formation of the coronary arteries in the arterial walls of dense plaques (seals), which will eventually destroy and deform the wall of the arteries and narrowing its lumen. The degree of narrowing of the lumen of the artery and impaired blood circulation determine the severity of symptoms of atherosclerosis of the coronary arteries. I must say that the symptoms (signs) of atherosclerosis of the coronary arteries are identical to the symptoms of coronary heart disease, the main cause of which is the name for atherosclerotic heart disease.
The symptoms of atherosclerosis of the heart vessels
The manifestations of atherosclerosis of the coronary arteries of the heart- It is coronary heart disease and angina pectoris and its complications - heart attacks and cardio. The main symptoms of atherosclerosis of the coronary arteries of the heart is angina, which is characterized by:
Crushing or burning pain in the chest, which gives in the back and in the left shoulder and occurs during exercise, stress;
Shortness of breath - the feeling of lack of air usually accompanies pain attack. Sometimes during the attack the patient is forced to take a sitting position, as in the supine position, he is suffocating;
In some cases, angina accompanied by dizziness, nausea, vomiting, headache.
Such seizures usually respond well to nitroglycerin treatment, which is considered the main drug, intended for acute treatment of angina attacks.
Complications of atherosclerosis of the coronary arteries
myocardial infarction Severe pain in the chest, resembling the pain ofangina (angina pectoris), which, however, do not pass under the influence of conventional treatment drugs nitroglycerin, by strong shortness of breath, possible loss of consciousness, rapid establishment of heart failure.
The gradual establishment of heart failure with reduced physical activity, the appearance of edema, shortness of breath.
