Patients with dilated cardiomyopathy should actively look for the cause of the disease and provide corresponding treatments, such as controlling infections, strictly limiting or abstaining from alcohol, treating relevant endocrine or autoimmune diseases, correcting electrolyte disorders, and improving nutritional imbalances, etc. In the early stages of dilated cardiomyopathy, although there is already enlargement of the heart and impairment of contractile function, there are no clinical manifestations of heart failure. At this stage, early pharmacological intervention should be actively implemented to slow down ventricular remodeling and further damage to the myocardium, delaying the progression of the disease. As the condition progresses, the patient's ventricular contractile function further decreases and clinical manifestations of heart failure appear. At this point, treatment should follow the guidelines for chronic heart failure. However, the specifics of the treatment and the choice of medication should be determined by a specialist based on the patient’s condition.
