Dilated Cardiomyopathy Causes. Dilated cardiomyopathy is a type of heart muscle disease that causes the heart chambers (ventricles) to thin and stretch, growing larger. It typically starts in the heart's main pumping chamber (left ventricle). Dilated cardiomyopathy makes it harder for the heart to pump blood to the rest of the body. | Dr. Najeeb

What is dilated cardiomyopathy?Cardiomyopathy is defined as degeneration of the heart muscle. As a result of this degeneration, the muscle becomes thinner, particularly the thick muscle wall of the left ventricle. The pressure of the blood inside the heart causes these thin walls to stretch resulting in a much larger heart. This condition is described as dilated cardiomyopathy (DCM). | Rubydoobydo
