Takotsubo Cardiomyopathy and Acute Infectious Diseases: A Mini-Review of Case Reports.

Takotsubo cardiomyopathy (TTC), also defined as "stress cardiomyopathy," is characterized by a systolic dysfunction localized in the apical and medial left ventricles. Takotsubo cardiomyopathy 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 TTC. 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. We found 26 articles dealing with 27 case reports (74% women). The mean age was 61.4 ± 13.7 years and bacterial infections were more frequent (n = 23, 85.2%). In 14 cases, there was a culture-based definition of the bacterial strain: gram+ in 8 cases (57.1%) and gram- in 6 cases (42.9%). Clinical outcome was always favorable
