Coronary atherosclerosis is a serious disease. The coronary arteries are the arteries that supply blood to the heart, and as plaque composed of deposits such as cholesterol builds up in the artery walls, it can lead to narrowing or occlusion of the coronary arteries. It may also be associated with factors such as high blood pressure, dyslipidemia, smoking, and diabetes. Patients may experience chest pain, palpitations (rapid heartbeat, often accompanied by panic), shortness of breath, chest pressure, arrhythmia, and fainting. Coronary atherosclerosis over 75% stenosis is serious and requires stent implantation to reopen the stenosis and increase blood supply to the heart to prevent myocardial infarction. If left untreated, coronary ischemia and myocardial hypoxia may occur, leading to life-threatening angina pectoris, acute myocardial infarction and heart failure. In addition, although coronary atherosclerosis is very serious, it is necessary to actively control the blood pressure, blood lipids, blood sugar according to the guidance of professional doctors. During the treatment period, you should also follow the doctor’s advice to quit smoking and limit alcohol, so as not to aggravate the condition.
