Different causes of myocardial ischemia correspond to different treatments, such as myocardial ischemia caused by cardiac overload with β-blockers and calcium antagonists; myocardial ischemia caused by vasoconstriction with nitrates; and distal myocardial ischemia caused by plaque formation with antiplatelet agents. 1. Myocardial ischemia caused by cardiac overload: β-blockers, such as propranolol, metoprolol, etc., can be used; calcium antagonists, such as verapamil, diltiazem, etc., can reduce myocardial oxygen consumption by lowering heart rate. 2. Myocardial ischemia caused by insufficient blood supply to the heart due to vasoconstriction: drugs that dilate coronary arteries, such as nitrate nitroglycerin, can be used to dilate the arteries so that the myocardium can regain blood supply. 3. Distal myocardial ischemia caused by plaque formation: anti-platelet drugs such as aspirin and clopidogrel can be used to prevent platelet aggregation, prevent plaque formation, and safeguard the blood supply to the distal myocardium. There are other causes of myocardial ischemia, please consult the hospital in time for active diagnosis and treatment. If you need the above drugs should be standardized under the guidance of a doctor.
