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. These can all lead to an irregular heartbeat, heart failure, a heart valve problem, or other complications.
Medical treatment and follow-up care are important. They can help prevent heart failure or other complications
