The 5-year survival rate for ischemic cardiomyopathy is around 50%. Ischemic cardiomyopathy is caused by severe coronary atherosclerosis, which causes severe stenosis, and myocardial infarction leading to extensive necrosis of the myocardium, causing remodeling of the heart, heart enlargement, and heart failure. Patients with ischemic cardiomyopathy are often hospitalized for recurrent heart failure and are at risk for malignant arrhythmias, ventricular tachycardia, and ventricular fibrillation. Once diagnosed with ischemic cardiomyopathy, it is usually important to take coronary artery disease secondary preventive medications and medications for the treatment of chronic heart failure on a regular basis, such as aspirin, clopidogrel, simvastatin, metoprolol, enalapril, spironolactone, and so on. Normally, it is important to maintain a negative balance of in and out, i.e., the daily urine output should be slightly more than the intake. And pay attention to cardiac rehabilitation therapy, common cardiac rehabilitation therapy are external counterpulsation therapy and exercise therapy. Regular follow-up in the hospital, cardiac ultrasound, electrocardiography, to understand the structure of the heart has no dynamic changes.
