Coronary heart disease and myocardial infarction which is serious

Coronary heart disease refers to coronary atherosclerotic heart disease. Myocardial infarction refers to acute myocardial infarction, which is usually more serious than coronary atherosclerotic heart disease.

Coronary atherosclerotic heart disease is a chronic cardiovascular disease caused mainly by insufficient blood supply to coronary arteries, resulting in myocardial ischemia, and the severity of the disease can be judged by the degree and frequency of myocardial ischemia. Mild ischemia may occur only during strenuous exercise or agitation, while severe coronary atherosclerotic heart disease may lead to severe cardiac insufficiency. However, acute myocardial infarction is a serious complication of coronary atherosclerotic heart disease, which is caused by sudden complete or partial occlusion of coronary artery, resulting in myocardial tissue ischemia and necrosis. Moreover, acute myocardial infarction belongs to emergency situation, which may lead to loss of cardiac function and arrhythmia, so it is necessary to seek medical treatment immediately for diagnosis and treatment.
