What is ischemic cardiomyopathy?

Ischemic cardiomyopathy (CM) is the most common type of dilated cardiomyopathy. In ischemic CM, the heart's main pumping chamber, the left ventricle, has been damaged by a lack of blood supply to the heart. This is usually caused by a heart attack or coronary artery disease (CAD). The result is an enlarged, dilated, and weakened heart that cannot adequately pump blood through the body.
