Myocardial ischemic heart disease, also known as coronary atherosclerotic heart disease, refers to the occurrence of atherosclerotic plaques in coronary artery vessels, narrowing the lumen and slowing down blood flow, causing ischemia in the terminal myocardium, which may lead to angina pectoris and acute myocardial infarction in severe patients. First of all, lifestyle intervention should be carried out, and it is recommended to strictly quit smoking and alcohol, and to have a light diet, low-fat diet and salt-restricted diet. In addition, active drug treatment is carried out, which requires the application of anti-platelet aggregation drugs such as aspirin and clopidogrel; the application of drugs such as atorvastatin calcium and rasulvastatin calcium to stabilize plaque and lower blood lipids; and strict control of hypertension and hyperglycemia. For those with severe symptoms and frequent angina attacks, coronary angiography should be performed to clarify the coronary stenosis, and stent intervention should be performed as appropriate.
