Restrictive physiology is a subtype of diastolic dysfunction

Restrictive physiology is a subtype of diastolic dysfunction characterized by impaired ventricular filling due to decreased compliance of the ventricles.

While restrictive physiology is often associated with restrictive cardiomyopathy (RCM), it can also occur in other conditions such as hypertrophic cardiomyopathy (HCM) and dilated cardiomyopathy (DCM).

In hypertrophic cardiomyopathy (HCM), diastolic dysfunction can occur due to the abnormal relaxation of the hypertrophied myocardium, leading to impaired ventricular filling despite preserved systolic function.

Similarly, in dilated cardiomyopathy (DCM), diastolic dysfunction may develop as the dilated ventricles lose their ability to relax and fill properly.
