Overview

Dilated cardiomyopathy is a disease of the heart muscle which primarily affects the heart's main pumping chamber, the left ventricle.[1] It is the most common type of cardiomyopathy and typically affects those aged 20 to 60.[2] The left ventricle of affected individuals becomes enlarged (dilated) and cannot pump blood to the body with as much force as a healthy heart can. The heart muscle also has difficulty contracting normally, which can lead to irregular heartbeats (arrhythmia), blood clots, or sudden death.[1][2] Over time, the heart becomes weaker and heart failure can occur.[2] While the cause of dilated cardiomyopathy is often unknown (idiopathic), some cases are acquired or inherited.[1][2]
