Oral medication for patients with coronary artery disease should be continued for life. After a clear diagnosis of coronary artery disease, the main oral medications are anti-platelet drugs such as aspirin or clopidogrel and lipid-lowering and plaque stabilizing drugs such as resulvastatin and atorvastatin. If angina is present, add nitrates and beta-blockers to reduce the onset of symptoms. For people with simple coronary artery disease who are stable and have not had a myocardial infarction, oral medications such as aspirin and resupristatin are sufficient. Coronary heart disease is a chronic disease that requires timely oral medication to prevent progression of the disease, so what is required after diagnosis of coronary heart disease is lifelong treatment, unless there are some specific complications.
