Patients with mild myocardial ischemia can be improved by medication, good living habits and diet. 1. Medications: β-blockers such as propranolol and metoprolol, non-dihydropyridine calcium antagonists such as verapamil and diltiazem can be used to reduce myocardial oxygen consumption and improve symptoms by lowering the heart rate. Some antiplatelet agents such as aspirin and clopidogrel can also be used to improve the prognosis. 2. Lifestyle habits: increase bed rest time, ensure enough sleep, have a reasonable routine, daily aerobic exercise, avoid overwork; at the same time, maintain a good attitude, control their emotions, not overly excited, happy and sad, which are not conducive to the recovery of myocardial ischemia. 3. Diet: low-salt and low-fat diet, reduce the intake of high-salt and high-fat food, and quit smoking and drinking.
