There is regional systolic dysfunction of the left ventricle, with hypokinesis of the middle and apical segments and hyperkinesis of the base. The ejection fraction is 40%. No other abnormalities are noted.
All coronary arteries are patent, with no evidence of spasm or thrombosis. Ventriculography shows apical ballooning with hyperkinesis of the basal segments and hypokinesis of the apical segments of the left ventricle.
