Apical ballooning of the left ventricle: first series in white patients

摘要: Background: A cardiac syndrome of “apical ballooning” was recently described, consisting an acute onset transient extensive akinesia the apical and mid portions left ventricle, without significant stenosis on coronary angiogram, accompanied by chest symptoms, ECG changes, a limited release markers disproportionate to extent akinesia. Until now, this has been reported only in Japanese patients. Objective: To describe 13 white patients who presented with over previous four years. Results: All but one were women mean age 62 Eight them pain, whom six had cardiogenic shock. In nine triggering factor identified: emotional stress three, trauma one, pneumonia asthma crisis exercise two, cerebrovascular accident one. all ventriculography showed very (“apical ballooning”) absence artery stenosis, not corresponding perfusion territory single epicardial artery. Mean maximal creatine kinase MB troponin rise 27.4 μg/l (range 5.2–115.7 μg/l, median 16.6 μg/l) 18.7 2.0–97.6 14.5 μg/l), respectively. Six treated intra-aortic balloon counterpulsation. One patient died multiple organ failure. On necropsy, no myocardial infarction found. 12 survivors, ventricular systolic function recovered completely within three weeks. Conclusions: This is first series be Despite dramatic initial presentation, ventricle weeks survivors.
