Coronary heart disease without special circumstances need to take long-term antiplatelet drugs, lipid regulation and plaque stabilization drugs, and improve myocardial ischemia drugs. If there is a serious adverse reaction, you need to stop taking the corresponding drugs. 1. Antiplatelet drugs: prevent thrombosis by inhibiting platelet aggregation, including aspirin, clopidogrel, tegretol, indobufen and so on. 2. Lipid regulating and plaque stabilizing drugs: lowering blood lipids and stabilizing plaque, commonly used statins such as atorvastatin and resuvastatin, statins are the first choice of lipid-lowering drugs for coronary heart disease. 3. Drugs to improve myocardial ischemia: β-blockers, commonly used bisoprolol, metoprolol, etc., the drug can not only improve myocardial ischemia, but also improve the prognosis of coronary heart disease. The above three types of drugs need to be taken for a long time if there is no serious adverse reaction, they can prevent myocardial infarction, improve the prognosis of coronary heart disease, and greatly reduce the probability of cardiovascular events in patients with coronary heart disease. Specific medications need to follow the doctor’s instructions.
