Dilated cardiomyopathy in the elderly

Dilated cardiomyopathy (DCM) is the main type of cardiomyopathy, accounting for about 70% to 80% of cardiomyopathy. It was previously called congestive cardiomyopathy. It is characterized by marked enlargement of the left ventricle or right ventricle or biventricular enlargement. It is characterized by enlarged heart, heart failure, arrhythmia, and embolism. Although the disease occurred in all age groups, the age of hospitalization was the highest among 20-49 years old. About 20% of DCM patients have a family history of cardiomyopathy.
