As a result, the heart is unable to pump blood as efficiently as usual. To compensate, the heart attempts to increase the amount of blood being pumped through the heart, leading to further thinning and weakening of the cardiac muscle. Over time, this condition results in heart failure. MONDO:0016333 hereditary dilated cardiomyopathy hypokinetic dilated cardiomyopathy, familial GARD:0020525 inherited
