Left ventricular apical ballooning--a novel cardiac disease mimicking acute coronary syndrome: a case report in a Caucasian patient.

The syndrome of "apical ballooning" consists of an acute onset of transient extensive akinesia of the apical portion of the left ventricle, without significant stenosis on the coronary angiogram, accompanied by chest symptoms, ECG changes, and a limited release of cardiac markers disproportionate to the extent of akinesia. So far, the vast majority of cases with this syndrome have been reported from Japanese patients and only a few cases of Caucasian patients have been described. Emotional or physical stress or other preceding triggering factors might play a key role in this cardiomyopathy, but the precise etiology remains unknown. We describe a case of "apical ballooning" in a white patient, who presented at our institution with this novel heart syndrome. Despite severe initial presentation, conservative medical management leads to good long term outcome in most patients.
