Key result
Typical apical contraction pattern in Takotsubo Syndrome was not associated with a significant difference in long-term all-cause mortality compared to atypical patterns (43% vs. 29%, p=0.17).
Why the study?
The relationship of different left ventricular contraction abnormality patterns in Takotsubo Syndrome to patient characteristics, clinical correlates, and long-term outcome is poorly understood.
Does the typical apical contraction pattern compared to atypical patterns affect long-term mortality in patients with Takotsubo Syndrome?

In patients with Takotsubo Syndrome, the typical apical contraction pattern is associated with higher myocardial damage markers but does not significantly increase long-term mortality compared to atypical patterns.
BACKGROUND: Takotsubo Syndrome (TTS) is diagnosed in 1-2% of all patients presenting with acute coronary syndrome. Next to the typical apical manifestation, other locations of left ventricular contraction abnormality are possible, but their relationship to patient characteristics, clinical correlates as well as long-term outcome are poorly understood. METHODS & RESULTS: We retrospectively analyzed 126 patients presenting TTS. Cases were categorized according to left ventricular contraction abnormality patterns: typical apical pattern (71%, n = 89) vs. atypical patterns (29%, n = 37). Cases with typical TTS showed significantly higher levels of troponin I (3.12 ng/ml vs. 1.32 ng/ml, p = 0.013) and creatin kinase (CK) on admission (461 (±1207)U/l vs. 173 (±177) U/l, p = 0.03) as well as peak CK (973 (±2860)U/l vs. 301 (±328) U/l, p = 0.03) and more often ischemia related ECG changes (p = 0.02). Follow-up data was available for 85% of the patients. Median FU time was 4.4 years (IQR 1.4-7.7 years). All-cause mortality during follow-up was 39%, with no significant difference between patients with typical or atypical TTS (43% vs. 29%, p = 0.17). In multivariate logistic regression analysis, only anemia was predictive for long-term mortality (OR 3.93, 95%CI 1.02-2.08, p = 0.015). The majority of surviving patients (69%) reported good quality of life, even though only 56% reported being symptom-free. CONCLUSION: Patients with TTS have poor long-term prognosis with an overall mortality of 39.1% within 4 years and nearly half of all patients report persisting symptoms. Even though the apical contraction pattern is associated with higher elevation of serum markers for myocardial damage, it was not associated with higher long-term mortality.

Gaede et al. (2021) conducted a cohort in Takotsubo Syndrome (n=126). Typical apical contraction pattern vs. Atypical contraction patterns was evaluated on All-cause mortality (p=0.17). Typical apical contraction pattern in Takotsubo Syndrome was not associated with a significant difference in long-term all-cause mortality compared to atypical patterns (43% vs. 29%, p=0.17).
