There is no effective drug treatment for coronary atherosclerosis, taking nitroglycerin and other nitrate coronary vasodilators is not the most effective way to relieve angina, but the disadvantage is that it cannot fundamentally improve the narrowing of blood vessels caused by coronary atherosclerosis. Xiaoning drugs for coronary artery disease mainly include the following categories: (1) anti-platelet agents such as aspirin; (2) β-blockers such as betalactam, which can be used for secondary prevention after myocardial infarction and can effectively reduce cardiac events, and are also the drugs of choice for patients with stable angina in terms of reducing morbidity and mortality; (3) angiotensin-converting enzyme inhibitors such as Kepone, which have good (4) lipid-lowering drugs, which can reduce acute coronary events and mortality in coronary artery disease and are the basic drugs for the treatment of coronary artery disease; (5) nitrates, which are not effective in reducing mortality in patients with acute myocardial infarction but can effectively relieve angina symptoms and frequency of attacks; (6) long-acting or slow-release dihydro arsenical calcium antagonists and non-dihydroarsenical calcium antagonists can relieve the symptoms of patients with stable angina without increasing the incidence of adverse cardiac events.
