what is  cardiomyopathy
Cardiomyopathy is a progressive disease of the myocardium, or heart muscle. In most cases, the heart muscle weakens and is unable to pump blood to the rest of the body as well as it should. There are many different types of cardiomyopathy caused by a range of factors, from coronary heart disease to certain drugs.
Cardiomyopathy, a disease of the heart muscle, primarily affects the left ventricle, which is the main pumping chamber of the heart. The disease is often associated with inadequate heart pumping and other heart function abnormalities.
