| AIM:To examine "Left ventricular apical ballooning syndrome"(ABS) research by analyzing the related literature.METHODS:Left ventricular apical ballooning syndrome (ABS), also defined as "stress cardiomyopathy," is characterized by a systolic dysfunction localized in the apical and medial left ventricles. Left ventricular apical ballooning syndrome is more prevalent in females and it is usually related to an event triggered by physical or emotional stress. We systematically explored PubMed and Embase medical information source to identify case reports showing association between infection and ABS. For each kind of infection, we collected a set of data, including pathogen, site of infection, clinical outcome, patient age and sex, and author and year of publication. RESULTS:We found27articles dealing with28case reports (71.4%women). The mean age was61.6±13.2years and bacterial infections were more frequent (n=24,85.7%). In14cases, there was a culture-based definition of the bacterial strain:gram+in8cases (57.1%) and gram-in6cases (42.9%). Clinical outcome was always favorable.CONCLUSION:At present, apical ballooning syndrome (ABS) has not been recognized diagnostic criteria, but also the lack of study of different treatment for specific evaluation, clinical diagnosis and treatment of the disease, most rely on their own experience of clinicians, diagnosis and individualized treatment according to patient characteristics. |
