“Cardiomyopathy (kahr-dee-o-my-OP-uh-thee) is a disease of the heart muscle. It causes the heart to have a harder time pumping blood to the rest of the body, which can lead to symptoms of heart failure. Cardiomyopathy also can lead to some other serious heart conditions.
There are various types of cardiomyopathy in all age groups.”
