Dilated cardiomyopathy is characterized by decreased contractility, thickened ventricular walls, and increased luminal volume. It may lead to heart failure with reduced ejection fraction.
Restrictive cardiomyopathy is characterised by decreased right atrial compliance, which manifests as a significantly elevated jugular venous pressure and prominent right heart failure.
