<br/><br/> The incidence of takotsubo stress cardiomyopathy (TSCM) in males is low compared with females. Gender-based differences in clinical outcomes of TSCM are not well characterized. The aim of this meta-analysis was to analyze whether gender-based differences are observed in TSCM clinical outcomes. A comprehensive literature search of PubMed, Embase, Cochrane Library database, and Web of Science was performed from inception to June 20, 2022, for studies comparing the clinical outcomes between male and female patients with TSCM. The primary outcome of interest was in-hospital all-cause mortality and cardiogenic shock. The secondary outcomes were cardiovascular mortality, receipt of mechanical ventilation, intra-aortic balloon pump, occurrence of ventricular arrhythmia, and left ventricular thrombus. A random-effects model was used to calculate the risk ratios (RR) and confidence intervals (CI). Heterogenicity was assessed using the Higgins I2 index. Twelve observational studies involving 51,213 patients (4,869 males and 46,344 females) were included in the meta-analysis. Male gender was associated with statistically significant higher in-hospital all-cause mortality compared with females in patients with TSCM (RR 2.17, 95% CI 1.77 to 2.67, p <0.001). The rate of cardiogenic shock was significantly higher in males with TSCM compared with females (RR 1.66, 95% CI 1.29 to 2.12, p <0.001). Our meta-analysis showed a difference in the clinical outcomes of TSCM between men and women. Male gender was associated with a two-fold greater in-hospital all-cause mortality risk compared with female gender. The higher mortality risk associated with male gender deserves further study, particularly whether it represents later recognition of the condition and disparities in treatments.
