PD.DCM

Dilated cardiomyopathy (DCM) is a myocardial (heart muscle) disorder in which there is dilation of all 4 cardiac chambers due to impaired contraction of the heart muscle during systole. In DCM the heart chambers are dilated rather than hypertrophied. While rare, DCM is the most common cause of congestive heart failure in the absence of other heart abnormalities. The etiology is genetic, non-genetic and acquired.
