Cardiogenic Shock Complicating Takotsubo Syndrome: Sex-Related Differences

Area of Science:

• Cardiology
• Cardiovascular Medicine
• Critical Care Medicine

Background:

• Takotsubo syndrome (TTS) exhibits sex-related differences, but data on cardiogenic shock (CS) in TTS is lacking.
• Understanding sex-specific outcomes in TTS complicated by CS is crucial for targeted treatment strategies.

Purpose of the Study:

• To investigate the clinical characteristics and outcomes of male and female patients experiencing cardiogenic shock due to Takotsubo syndrome.
• To determine if sex influences short-term (in-hospital) and long-term (5-year) mortality in TTS patients with CS.

Main Methods:

• Retrospective analysis of 412 patients with Takotsubo syndrome and cardiogenic shock.
• Comparison of demographic, clinical, and outcome data between male and female patients.
• Matched cohort analysis to assess mortality differences, adjusting for potential confounders.

Main Results:

• Male patients (17.2%) were older, more likely to be smokers, and had a higher prevalence of neoplasms.
• Male TTS-CS patients presented with lower left ventricular ejection fraction and required more invasive mechanical ventilation.
• Despite differences in clinical presentation and comorbidities, male sex was not significantly associated with in-hospital or 5-year mortality.

Conclusions:

• Cardiogenic shock in Takotsubo syndrome is associated with high in-hospital and 5-year mortality rates.
• Sex does not appear to be a significant determinant of mortality in patients with Takotsubo syndrome and cardiogenic shock.
• Short- and long-term mortality rates are comparable between men and women suffering from TTS-induced CS.
