Do clinical outcomes differ between patients with hypokinetic non-dilated cardiomyopathy and classic dilated cardiomyopathy?
Patients with hypokinetic non-dilated cardiomyopathy have similar mortality risk to those with classic dilated cardiomyopathy, despite presenting with less severe symptoms and remodeling.
LV dilatation was absent in more than one-fifth of DCM patients. HNDC patients had less severe heart failure symptoms, less advanced cardiac remodelling, and required lower diuretics dosages. On the other hand, "classic" DCM and HNDC patients did not differ in terms of all-cause mortality, CV mortality, and composite endpoint.
