Some early heart failure due to dilated heart disease (i.e., dilated cardiomyopathy) can be cured, while advanced heart failure and heart failure with structural lesions cannot be cured. If the heart failure is severe, the patient’s survival time will be significantly shortened, but aggressive treatment can help prolong the patient’s life and improve the quality of his or her survival. Dilated cardiomyopathy, the exact cause of which is unknown, is characterized by enlargement of the entire heart and thinning of the ventricular walls. Dilated cardiomyopathy has no obvious symptoms in the early stages and heart failure can occur in the late stages. When heart failure occurs in patients with dilated cardiomyopathy, the condition progresses faster, and there is a risk of sudden death at any time. Moreover, patients are prone to complications such as ventricular fibrillation and other malignant arrhythmias, and the survival time will be significantly shortened, with a very low 5-year survival rate. Patients with dilated cardiomyopathy should be actively treated to control the onset of heart failure, and once heart failure occurs, should follow the doctor’s instructions to actively treat to slow down the progress of the disease.
