is a disease of the heart muscle. Dilated cardiomyopathy is the dilation of the cardiac cavities affecting both ventricles. The expansion mechanism appears to compensate for the failure of the heart to ensure adequate blood flow; this expansion is accompanied by an increase in the thickness of the heart muscle. In the advanced stage, it no longer works properly and cardiac output decreases: dilated cardiomyopathy leads to heart failure
and clinical signs of chronic heart failure. There are several causes including chronic alcoholism
, heart rhythm disorders, myocardial infections... This disease requires medication and regular monitoring and at advanced stages, a transplant may be necessary.
