Dilatation of the left ventricular cavity on dipyridamole thallium-201 imaging: a new marker of triple-vessel disease.

abstract：:The extent and time course of recovery of left ventricular function were investigated in 29 patients with no previous symptoms who had acute nonischemic congestive cardiomyopathy and left ventricular ejection fraction of 0.22 +/- 0.07. Improvement in left ventricular ejection fraction by at least 0.05 was observed in ...
