BACKGROUND: Transient @entity661 also called @entity661 is defined as a syndrome consisting of stress induced apical ballooning of the left ventricle and normal coronary arteries. The majority of the published reports are case reports or case series with a small number of @entity1 . The goal of this study was to perform statistical analysis of reported cases and case series in the literature in order to study demographic, clinical characteristics and prognosis of this syndrome. METHOD: A PubMed search of the terms transient left ventricular apical ballooning, Tako-Tsubo, takotsubo, and apical @entity296 was conducted for this study. All reports that contained information about individual @entity1 were included in the statistical analysis. RESULTS: The majority of the @entity1 were @entity1 (93.5%). Asians were the largest group (57.2%) followed by Caucasians (40%). The presentations mimics an acute @entity583 . The most frequent presenting symptom was @entity662 (65.9%) followed by @entity1353 (16.2%). ST elevation was the most common ECG abnormality (87.5%). Contrary to most reports, this is not a benign disease with complications occurring in 18.9% and death in 3.2%. The most common complication was shock followed by @entity1002 formation and @entity712 . CONCLUSION: @entity661 occurs most commonly in @entity1 and is associated with high complication rate. There are significant differences in presenting symptoms between race and gender which warrant further investigation.
