Recovery of Left Ventricular Function and Long-Term Outcomes in Patients With Takotsubo Syndrome
Authors' conclusion
Late recovery of LV function after TTS is associated with reduced short- and long-term survival.
Study context
- Population
- Patients with Takotsubo syndrome (TTS) in the RETAKO registrymedian age 73 years, 13% men
- Participants
- 1,463 patients

- Late recoveryn = 373
- Early recoveryn = 1,090reference
- Outcome
- All-cause mortality
- Follow-up
- 4-year follow-up

Main finding
As reported in the abstract
Adjusted hazard ratio (95% CI)
Late recoveryvs Early recovery
1.31(1.12–1.60)
Every additional 10-day delay in time-to-LV recoveryrisk of death increasing by 8%
1.08(1.04–1.13)
Observational data: associations, not effects.
Further findings
Independent predictors of late recovery
- Older age, history of neurological disorders, bystander CAD, active cancer, physical triggers, elevated inflammatory biomarkers, cardiogenic shock and lower LVEF at admission
