Myocardial ischemia is usually the result of lowered blood pressure and blockage of coronary arteries, which leads to insufficient blood and oxygen supply to the heart. Drugs used to treat myocardial ischemia include nitrate drugs, antithrombotic drugs, beta-blockers, calcium channel blockers and so on. 1. Nitrate drugs: such as nitroglycerin tablets, isosorbide nitrate tablets and other drugs, usually used in myocardial ischemic attack, can rapidly dilate the coronary artery, increase myocardial blood supply. 2. Antithrombotic drugs: Antithrombotic drugs have the effect of anti-platelet aggregation and adhesion, which can prevent the formation of arterial thrombosis and embolism. Commonly used drugs include aspirin enteric-coated tablets, clopidogrel tablets and other drugs. 3. β-blockers: such as metoprolol tablets, bisoprolol fumarate tablets and other drugs. They can reduce the contractility and heart rate of the heart and decrease myocardial oxygen consumption, thus reducing angina attacks and increasing exercise tolerance. 4. Calcium channel blockers: such as nifedipine tablets and diltiazem hydrochloride tablets can reduce myocardial oxygen consumption, effectively improve myocardial ischemia and reduce the symptoms of angina pectoris. Patients with myocardial ischemia should go to the cardiovascular department of the hospital in time for examination and treatment, and all drugs must be used in a standardized way under the guidance of doctors.
