Introduction: Takotsubo Syndrome (TTS), also known as Stress Induced Cardiomyopathy, is characterized by reversible left ventricular dysfunction without obstructive coronary disease, and largely affects post-menopausal women. However, limited data suggest increased mortality risk in men. We sought to compare national in-hospital outcomes between men and women admitted with TTS. Methods: All patients above 18 years who were admitted with primary diagnosis of TTS between 2012-2017 were identified by International Classification of Diseases (ICD)-9 and ICD-10 diagnostic codes in the National Inpatient Sample (NIS) Database. The primary endpoint was in-hospital all-cause mortality. Secondary endpoints included in-hospital complications, total cost, and duration of hospitalization. Results: A total of 8732 patients (90.8% female) were admitted with primary diagnosis of TTS. Women with TTS were older compared to men (66.9±12.4 vs. 63.1±15.7 years, p Conclusion: TTS occurs predominantly in women but carries increased risk of in-hospital mortality in men, especially when complicated by cardiogenic shock. Perhaps improved risk stratification and early identification of patients with signs of shock or hemodynamic instability may help to improve outcomes.
