Coronary atherosclerotic heart disease is a heart disease caused by atherosclerotic lesions in the coronary vessels that narrow or block the lumen of the vessels, resulting in ischemia, hypoxia or necrosis of the myocardium, often referred to as “coronary heart disease”. However, the scope of coronary artery disease may be broader, including inflammation, embolism, etc., resulting in narrowing or occlusion of the lumen. The World Health Organization classifies coronary artery disease into five major categories: asymptomatic myocardial ischemia (occult coronary artery disease), angina pectoris, myocardial infarction, ischemic heart failure (ischemic heart disease), and sudden death. In clinical practice, they are often divided into stable coronary artery disease and acute coronary syndromes.
