There is hope for living 30 years in dilated cardiomyopathy. Dilated cardiomyopathy is the enlargement of the right and left two ventricles and the decline in ventricular contractility, resulting in heart failure, the onset of early patient symptoms are not obvious, with the development of aggravation of the disease, the emergence of heart failure and other symptoms. The common clinical manifestations of dilated cardiomyopathy include dyspnea, sitting breathing, unable to lie down mainly; double lower extremity edema, depressed, aggravating dyspnea; cough pink foamy sputum; and the emergence of comorbidities such as cardiac arrhythmia. The current treatment principle of dilated cardiomyopathy is to actively search for the cause of the disease, such as controlling infections, smoking and alcohol cessation. The application of enhanced angiotensin converting enzyme inhibitors to slow down ventricular remodeling and myocardial damage, the application of β-blockers, diuretics and other drugs to improve cardiac function and reduce heart failure. Cardiac replacement can be done for severe disease. Once the patient appears similar to the symptoms of dilated cardiomyopathy, timely to the hospital, timely and clear diagnosis, standardized treatment, can greatly extend the patient’s life.
