Cardiomyopathy is a disease of the heart muscle that weakens the heart's ability to pump blood effectively. The main types are dilated, hypertrophic, and restrictive cardiomyopathy. Dilated cardiomyopathy is the most common type and causes the heart chambers to enlarge over time. Treatment involves managing symptoms and risk factors with medications, lifestyle changes, surgery such as implantable devices or transplant, and treating any underlying causes. A heart transplant may be an option for severe cases but carries risks of organ rejection, infection, and side effects of immunosuppressant drugs.
