Myocardial ischemia is insufficient blood supply to the myocardium caused by the narrowing of the coronary arteries of the heart, it is not something to eat to supplement can be relieved, the application of drugs to improve myocardial ischemia, prevention of heart attack. Drugs to improve myocardial ischemia mainly include: ① β-blockers: slow down the heart rate, reduce myocardial contractility, reduce myocardial oxygen consumption, such as bisoprolol, metoprolol. ② Calcium channel receptor blockers: dilate coronary arteries, relieve coronary artery spasm, such as verapamil, diltiazem. ③ Nitrates: dilate the coronary artery to increase blood flow, such as isosorbide nitrate, isosorbide mononitrate. Prevention of heart attack drugs include: ① antiplatelet drugs: inhibit platelet aggregation. Prevent thrombosis, such as Tegretol, aspirin, clopidogrel. ② lipid-lowering drugs: lowering blood lipids to stabilize plaque, such as atorvastatin, resuvastatin, ezetimibe. Myocardial ischemia need to go to the hospital, under the guidance of the doctor to use drugs.
