The difference between dilated cardiomyopathy and heart failure is roughly as follows: 1. Dilated cardiomyopathy is similar to normal in the early stages, with no significant differences, and is difficult to detect as dilated cardiomyopathy, while patients with heart failure generally show dyspnea, shortness of breath and swelling of the lower extremities. Patients with dilated cardiomyopathy may be born with genetic problems in this area, and wait until the disease progresses 10-20 years, or even 30-40 years will show symptoms of heart failure, the final outcome of dilated cardiomyopathy is heart failure; 2. In terms of treatment, if dilated cardiomyopathy can be screened by medical examination in the early stage, usually only 2-3 drugs are needed to control the rapid progress of the disease. If it has progressed to the stage of heart failure, 5-6, or even 7-8 drugs need to be taken to improve the patient’s quality of life and prolong the patient’s survival cycle; 3. In terms of causes, dilated cardiomyopathy is clinically observed to have a tendency to gather in families, while heart failure is a very broad concept, and many heart diseases, including hypertension, coronary artery disease, perinatal cardiomyopathy, or restrictive cardiomyopathy, rheumatic heart disease, these It is more directly explained that heart failure is the end-stage manifestation of all heart diseases, and heart expansion disease is only one of the heart diseases that will go to the end stage.
