BACKGROUND: Takotsubo cardiomyopathy (TCM) is classically associated with significant gender disparities, such that it is more prevalent in females, but the clinical outcomes are worse for male patients. The goal of this study was to assess contemporary gender disparities in clinical outcomes of TCM hospitalizations and to determine predictors of male in-hospital mortality.
METHODS: This was a retrospective analysis involving adult hospitalizations for TCM in the U.S between 2016 and 2020. Multivariable Logistic regression was used to estimate Odds Ratio (OR) for in-hospital mortality between the two genders. Univariable Cox regression was performed to identify predictors associated with in-hospital mortality for male hospitalizations. All factors from the univariable analysis with p < 0.20 were included in a multivariable Cox regression model.
RESULTS: A total of 199,920 patients with TCM were identified. Female patients with TCM had 50% lower risk of in-hospital mortality compared to male patients (Adjusted OR 0.50, 95% CI 0.46-0.55, p < 0.001). Older age, higher Charlson comorbidity index, history of intracranial hemorrhage, cardiac arrest, need for vasopressor agents, mechanical intubation, and cardiogenic shock without the use of temporary mechanical circulatory support (MCS) were associated with higher in-hospital male mortality.
CONCLUSIONS: Although TCM is more prevalent among females, gender disparities exist in the clinical outcomes of TCM patients. Cardiac arrest and cardiogenic shock without the use of temporary MCS were found to be the most significant predictors of male in-hospital mortality. Cardiogenic shock with use of temporary MCS did not lead to higher male in-hospital mortality.
