Mild myocardial infarction is mainly treated with medication, and commonly used drugs include antimyocardial ischemic drugs, antiplatelet therapy, anticoagulation therapy and lipid regulation therapy. 1. Anti-myocardial ischemic drugs mainly include nitrate drugs, β-receptor antagonists, calcium channel blockers, etc. The common drugs are isosorbide nitrate, metoprolol, diltiazem, of which calcium channel blockers are the second choice. 2. Antiplatelet therapy: mostly oral-based, can choose aspirin, cilostazol. 3. Anticoagulation therapy: Unless there is a contraindication, anticoagulation therapy should be adopted on the basis of antiplatelet therapy, which mainly includes anticoagulant drugs such as ordinary heparin, low molecular heparin, sodium sulfadiazine heparin, and bivalirudin, etc., and it can be injected intravenously, subcutaneously, or orally to minimize the formation of thrombus. 4. Lipid regulation therapy: early use of statins such as simvastatin and resuvastatin. 5. Angiotensin-converting enzyme inhibitors and angiotensin II receptor antagonists: for patients with non-ST-segment elevation myocardial infarction, long-term use can reduce the probability of cardiovascular events, and common drugs include enalapril and valsartan. Symptoms of myocardial infarction should be timely consultation, treatment under the guidance of the doctor, daily attention to avoid strenuous exercise, pay attention to rest, pay attention to the combination of work and rest.
