Key result
Posterior cerebral subarachnoid hemorrhage is linked to ~46% higher Takotsubo cardiomyopathy odds versus anterior circulation.
Why the study?
The relationship between the anatomic locations of subarachnoid hemorrhages and the development of Takotsubo cardiomyopathy was not well understood.
Does subarachnoid hemorrhage in the posterior cerebral circulation increase the risk of developing Takotsubo cardiomyopathy compared to the anterior circulation?

Posterior SAH may warrant targeted Takotsubo vigilance; leaves open whether location modifies risk stratification or outcomes.
Meta-Analysis (n=1,508)
Does subarachnoid hemorrhage in the posterior cerebral circulation increase the risk of developing Takotsubo cardiomyopathy compared to the anterior circulation?
Odds Ratio: 1.46 (95% CI 1.01–2.1)
p-value: p=0.0425
Subarachnoid hemorrhage in the posterior cerebral circulation is associated with a modestly higher risk of developing Takotsubo cardiomyopathy compared to anterior circulation hemorrhage.
Eter et al. (2024) conducted a meta-analysis in Subarachnoid hemorrhage and Takotsubo cardiomyopathy (n=1,508). Posterior circulation subarachnoid hemorrhage vs. Anterior circulation subarachnoid hemorrhage was evaluated on Occurrence of Takotsubo cardiomyopathy (OR 1.46, 95% CI 1.01-2.10, p=0.0425). Subarachnoid hemorrhage in the posterior cerebral circulation was associated with a significantly higher odds of developing Takotsubo cardiomyopathy compared to the anterior circulation (OR 1.46).
