[Transient ventricular dysfunction after emotional stress].

We describe a patient who developed severe ventricular dysfunction and cardiogenic shock after intense emotional stress. Her subsequent course was favorable, with complete recovery of left ventricular systolic function. The coronary arteries were normal and no specific etiologic agent was demonstrated. Her clinical picture was compatible with transient left ventricular apical ballooning. [I123]metaiodobenzyl guanidine cardiac scintigraphy showed a marked decrease in cardiac sympathetic nerve activity. We discuss the pathophysiologic mechanisms of this syndrome.
