Cardiomyopathy, or heart muscle disease, is a type of progressive heart disease in which the heart is abnormally enlarged, thickened, and/or stiffened. As a result, the heart's ability to pump blood is weakened, often causing heart failure and the backup of blood into the lungs or rest of the body. There are three main types of cardiomyopathy - dilated cardiomyopathy, hypertrophic cardiomyopathy, and restrictive cardiomyopathy. Follow the links below to find WebMD's comprehensive coverage of what cardiomyopathy looks like, how it develops, how it is treated, and much more.
