Prognostic relevance of arrhythmic and QTc burden in takotsubo cardiomyopathy: A systematic review and meta-analysis.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction: Takotsubo cardiomyopathy is characterized by stress-induced systolic dysfunction of the left ventricle that is largely reversible and not related to coronary ischemia. Patients with Takotsubo cardiomyopathy can often develop concurrent arrhythmias and prolonged QTc interval, which have been shown to contribute to significant morbidity and mortality in prior retrospective studies. Hence, we conducted a comprehensive systematic review and meta-analysis to characterize the risk of atrial arrhythmias, life-threatening arrhythmias, and QTc prolongation on clinical outcomes in patients with Takotsubo cardiomyopathy. Methods: We searched PubMed and EMBASE databases from inception to April 2024. A total of 13 studies were eligible for data collection across the three subgroups. Results: Atrial and life-threatening arrhythmias in Takotsubo cardiomyopathy have an increased risk of in-hospital mortality and cardiogenic shock, a finding that was not observed in patients with prolonged QTc. Upon univariate analysis of the QTc subgroup, younger age and the presence of ST-Elevation were identified as additional negative prognostic indicators of adverse outcomes in Takotsubo cardiomyopathy. Conclusion: Our study demonstrates the increased risk of different arrhythmic profiles in Takotsubo cardiomyopathy. Further investigation is needed to identify pathophysiological mechanisms and tailored anti-arrhythmics to improve outcomes in this unique subset of Takotsubo patients.
