Frequency of echocardiographic improvement in left ventricular cavity size and contractility in idiopathic-dilated cardiomyopathy.

In this study, we used 2-dimensional echocardiography to serially evaluate 32 patients with recent onset dilated cardiomyopathy. We found that in 12 patients (37%) there was resolution of left ventricular dilation as well as concomitant normalization of left ventricular contractility.
