Patients with coronary artery disease with chest tightness and shortness of breath should take aspirin and atorvastatin, which are the most basic drugs for the treatment of coronary artery disease and can play a role in slowing down the progression of coronary artery disease and reducing the incidence of myocardial infarction. If patients with coronary artery disease experience chest tightness and shortness of breath, they can also add symptomatic relief drugs, such as vasodilators, isosorbide mononitrate, isosorbide nitrate or nitroglycerin. Because shortness of breath is the most common form of coronary heart disease attack, when patients experience shortness of breath after exertion or anger, which lasts for a few minutes and then relieves itself, this is a typical symptom of angina pectoris. When angina attacks, nitroglycerin or quick-acting heart pills can also be taken to quickly relieve the symptoms.
