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

As the chamber gets bigger, its thick muscular wall stretches, becoming thinner and weaker. This affects the heart's ability to pump enough oxygen-rich blood to the rest of the body. | Dr. Najeeb | Facebook
