Cardiomyopathy (kahr-dee-oh-my-OP-uh-thee) is a disease that weakens and enlarges your heart muscle. There are three main types of cardiomyopathy — dilated, hypertrophic and restrictive. Cardiomyopathy makes it harder for your heart to pump blood and deliver it to the rest of your body. Cardiomyopathy can lead to heart failure.
Cardiomyopathy can be treated. The type of treatment you'll receive depends on which type of cardiomyopathy you have and how serious it is. Your treatment may include medications, surgically implanted devices or, in severe cases, a heart transplant.
