Heart ischemia is caused by the narrowing of the blood vessels of the heart, can not rely on supplementation of certain substances to relieve, need to be under the guidance of a doctor to take medication with metoprolol, nifedipine, aspirin and other drugs, serious ischemia caused by infarction also need to be intervened in the stent or thrombolytic therapy. 1. Drug therapy includes drugs to improve myocardial ischemia and drugs to prevent heart attack. (1) Drugs to improve myocardial ischemia: Receptor blockers: reduce myocardial contractility, reduce myocardial oxygen consumption, commonly used bisoprolol, metoprolol and so on. Calcium channel receptor blockers: dilate coronary artery, reduce myocardial oxygen consumption to improve myocardial ischemia, commonly used nifedipine, verapamil, etc.. Nitrates: dilate the coronary artery to improve myocardial ischemia, commonly used isosorbide nitrate, isosorbide mononitrate and so on. (2) Prevention of heart attack drugs: lipid-lowering drugs to reduce blood lipids and stabilize plaque, such as atorvastatin and ezetimibe; antiplatelet drugs to inhibit platelet aggregation and prevent thrombosis, such as aspirin, tegretol, indobufen and clopidogrel. 2. Interventional stenting: through interventional means, stents are put into the severely narrowed or even occluded places of coronary arteries in order to achieve reperfusion of blood flow. 3. Thrombolytic therapy: myocardial ischemia resulting in infarction, unconditional stenting within 2 hours. If there is no absolute contraindication (active bleeding) thrombolytic therapy. 4. In addition to stenosis and other reasons, many patients will also have anemia, insufficient blood volume reasons, if the anemia, the need for targeted blood and iron supplementation and other treatments. Myocardial ischemia need to go to the hospital, under the guidance of the doctor to choose the appropriate treatment, do not self-diagnosis of medication.
