Key result
Takotsubo syndrome carries comparable long-term mortality to ACS, with physical triggers linked to higher risk.
Why the study?
Prognosis of Takotsubo syndrome remains controversial due to scarce data, and the prognostic impact of different triggering factors remains elusive.
Does Takotsubo syndrome have a different long-term mortality risk compared to acute coronary syndrome, and how do triggering factors affect prognosis?
Population
1,613 patients with Takotsubo syndrome from the International Takotsubo Registry
Comparison
Takotsubo syndrome vs age- and sex-matched ACS, and comparisons by triggering conditions
Design
Registry-based matched cohort study

“Overall, TTS patients had long-term outcomes comparable to age- and sex-matched ACS patients. Also, we demonstrated that TTS can either be benign or a life-threating condition depending on the inciting stress factor. We propose a new classification based on triggers, which can serve as a clinical tool to predict short- and long-term outcomes of TTS.”
“We probably need to look in the future at something which is far more personalized to this particular condition, targeted to the pathophysiology of Takotsubo itself rather than extrapolated from another condition. We need to do more work. We need to find out what really helps these patients in the long term.”
“suggests the importance of further research for more appropriate management of patients with acute and long-term TTS.”
TTS trigger type should inform individualized risk discussions; leaves open whether trigger-specific interventions improve outcomes versus standard ACS care.

Does Takotsubo syndrome have a different long-term mortality risk compared to acute coronary syndrome, and how do triggering factors affect prognosis?
Takotsubo syndrome has a long-term mortality risk comparable to ACS overall, but prognosis varies significantly based on the inciting stress factor, with physical triggers indicating higher mortality.
Ghadri et al. (2018) conducted a cohort in Takotsubo syndrome (n=1,613). Takotsubo syndrome vs. Age- and sex-matched acute coronary syndrome (ACS) patients was evaluated on Long-term mortality. Takotsubo syndrome (N=1,613) had comparable long-term mortality to ACS overall, though mortality was higher for physical triggers (39%) and lower for emotional triggers (30%) compared to ACS.
