Cardiomyopathy

Heart Disease

Restrictive cardiomyopathy

Restrictive cardiomyopathy is the least common form and occurs when the heart muscle of the ventricles, or myocardium, is excessively rigid, impairing the filling of the ventricles with blood between heartbeats. Tiredness, shortness of breath and swollen feet and hands typically occur.

Arrhythmogenic right ventricular cardiomyopathy

In another form of cardiomyopathy, the heart muscle is replaced by fibrous scar and fatty tissue. This may occur after a heart attack, where muscle is damaged – the right ventricle tends to be most affected. The right side of the heart may first thicken and later dilate – become thinner. It may lead to disordered electrical activity, and in some cases problems with the heart’s pumping action.
