Reversal of myocardial ischemia requires aggressive treatment of the primary cause and prevention of comorbidities, and symptoms can usually be reversed after aggressive treatment of the primary cause of myocardial ischemia. For example, if myocardial ischemia is caused by factors such as hyperthyroidism, the patient can take drugs such as Sage to actively treat the hyperthyroidism, and at the same time give drugs for cardiomyocyte nutrition and blood supply to improve the heart function, in which case myocardial ischemia can be reversed. For example, if myocardial ischemia is caused by cardiogenic diseases such as unstable angina pectoris in coronary artery disease, myocardial ischemia can be reversed by taking nitrate drugs, ACEI drugs, anti-platelet aggregation drugs, lipid-lowering drugs and β-blockers, in addition, myocardial ischemia can be reversed and heart function can be improved by taking appropriate Chinese medicine.
