Myocardial ischemia refers to myocardial damage caused by myocardial oxygen depletion and insufficient oxygen and blood supply to the coronary arteries. Nitrate drugs, beta blockers and statins can be taken to alleviate the improvement. 1. Nitrate drugs: Nitrate drugs can dilate the veins, reduce cardiac preload, lower the left ventricular end-diastolic pressure, reduce myocardial oxygen consumption, improve the left ventricular local and overall function. Such as nitroglycerin, isosorbide mononitrate and other drugs. 2. β-blockers: mainly act on myocardial β1 receptor, can reduce myocardial oxygen consumption, reduce repeated myocardial ischemia, reduce the occurrence of myocardial infarction, and play an important role in improving the recent and long-term prognosis. Such as metoprolol and other drugs. 3. Statin drugs: these drugs mainly have the effect of regulating blood lipids and improving endovascular cells, which can effectively reduce blood lipids. Such as atorvastatin, simvastatin and other drugs. In addition to the above drugs, there are other optional drugs, but under the guidance of the doctor, according to the cause of the disease for medication.
