Coronary heart disease and stable angina pectoris

Coronary heart disease and stable angina are different types of coronary atherosclerotic heart disease and differ mainly in severity and prognosis. Coronary heart disease refers to heart disease caused by myocardial ischemia, hypoxia or necrosis due to stenosis or obstruction caused by coronary atherosclerosis, while stable angina pectoris refers to acute and temporary myocardial ischemia and hypoxia syndrome caused by increased myocardial load on the basis of fixed severe stenosis of coronary arteries. Specifically, the difference between the two is mainly reflected in the following aspects: the nature of pain: chest pain caused by coronary heart disease is usually crushing, tightening or suffocating pain, which can be accompanied by a sense of dying, lasting for a few minutes to more than ten minutes, and can be relieved by rest or nitroglycerin. The chest pain of stable angina pectoris is usually exertional pain, that is, it appears during physical activity or emotional excitement. Rest or nitroglycerin can be quickly relieved. Frequency of attack: The frequency of chest pain caused by coronary heart disease is not fixed, but several times a day or several times a day. The frequency of chest pain attack of stable angina pectoris is relatively fixed, generally several times a week or more. Causes: Chest pain attacks caused by coronary heart disease are often related to physical activity, emotional excitement, satiety, cold and other factors. Chest pain attacks of stable angina are often related to physical activity, such as walking fast, going upstairs, climbing, etc. Prognosis: The prognosis of coronary heart disease is poor. If not actively treated, it can develop into serious complications such as myocardial infarction, heart failure, arrhythmia, and even life-threatening. The prognosis of stable angina pectoris is relatively good, through active treatment, symptoms can be effectively controlled, reduce the occurrence of complications. In short, although coronary heart disease and stable angina pectoris are different types of coronary atherosclerotic heart disease, but the severity and prognosis are different. For patients with coronary heart disease or stable angina pectoris, they should actively seek medical treatment and follow the doctor's advice to control the disease and reduce the occurrence of complications.
