Dilated cardiomyopathy is difficult to cure once it appears. Dilated cardiomyopathy is a cardiomyopathy with ventricular enlargement accompanied by systolic dysfunction, which is related to family genetics or can develop on its own. It is asymptomatic in the early stage, and can present with dyspnea, loss of appetite, and intractable low blood pressure, with subsequent manifestations such as heart failure, arrhythmia, and sudden death, which are usually treated with medication to slow down the progression of the disease. The treatment of dilated cardiomyopathy mainly identifies the cause of the disease, treats the symptoms, controls infection, solves the primary underlying disease, avoids the use of drugs that are harmful to the heart, corrects electrolyte disorders, regulates cardiac function, and can also be treated by heart transplantation, but with a poorer prognosis. The purpose of the treatment is to stop the underlying disease from damaging the myocardium, to control the cardiac arrhythmia, to prevent sudden death, embolism, etc, and to improve the survival rate. Specific treatment should be carried out under the formal guidance of a doctor.
