Myocardial ischemia in the vast majority of cases cannot be cured, and only a small number of patients with myocardial ischemia may be completely cured, depending mainly on the underlying cause of the induced myocardial ischemia. Myocardial ischemia patients can be cured as follows: a. Can be cured: For example, myocardial ischemia caused by severe anemia, severe hyperthyroidism, rapid atrial fibrillation, supraventricular tachycardia and other factors, usually the symptoms of myocardial ischemia can be relieved after the cause is corrected, so patients with myocardial ischemia induced by such causes can be cured. Second, incurable: myocardial ischemia caused by various primary organic heart diseases and diseases related to narrowing of heart vessels, such as coronary artery disease, due to the formation of coronary artery atherosclerosis, resulting in different degrees of lumen narrowing, which induces insufficient myocardial blood supply. Although these patients can be treated with coronary artery stenting surgery or coronary artery bypass surgery to relieve myocardial ischemia, this ischemia cannot be completely cured and requires long-term improvement of poor lifestyle and long-term treatment with secondary prevention drugs for coronary artery disease to slow down the progression of plaque and maintain the stability of the disease. In addition, organic diseases originating from the heart or blood vessels, such as hypertension and hypertrophic obstructive cardiomyopathy, may also induce myocardial ischemia. Although it is possible to apply drugs to control blood pressure or to treat hypertrophic obstructive cardiomyopathy with drugs, chemical ablation, or surgical septal resection, these etiologies, once developed, are difficult to eliminate completely and require long-term medication to maintain. Therefore, myocardial ischemia caused by the above etiologies is often difficult to be cured.
