Non-dilated left ventricular cardiomyopathy vs. dilated cardiomyopathy: clinical background and outcomes.

There was no significant difference in the incidence of cardiac events between NDLVC-REF and DCM. Among NDLVC-REF patients, 18% of patients who showed LV dilatation after diagnosis had poor outcomes. Therefore, both NDLVC-REF and DCM patients may require equivalent attention to follow-up and regular assessment of LV function.
