Survival benefit of secondary prevention medical therapy in takotsubo cardiomyopathy: a Bayesian network meta-analysis.
Article in European heart journal open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Aims: Takotsubo cardiomyopathy (TTC) is a form of transient left ventricular systolic dysfunction without evidence of complicated coronary artery disease. Efficacy of medical therapy in secondary prevention of all-cause mortality is not well established. We performed a systematic review and network meta-analysis to compare survival benefit of secondary prevention medical therapy in patients with TTC. Methods and results: PubMed, Embase, and Cochrane were searched up to 6 January 2024. Eligible studies included multivariable-adjusted or propensity-matched studies of patients receiving medical therapy with beta-blockers, angiotensin-converting enzyme inhibitors (ACE) or angiotensin receptor blockers (ARBs), aspirin, and statins after an index presentation with TTC. The primary outcome was all-cause mortality at any time point. Secondary outcome was TTC recurrence. Random-effect hierarchical Bayesian meta-analysis was performed. We identified 13 observational studies. Takotsubo cardiomyopathy mortality was reported in 435 (4.7%) out of 9237 patients, across a median follow-up of 2.18 years. Mean age was 69.7 ± 12.5 years, and 7906 patients (90.7%) were females. Beta-blockers were associated with a statistically significant reduction in mortality compared to control [hazard ratio (HR) 0.65, 95% confidence interval (CI) (0.55-0.77)]. ACE inhibitors/ARBs showed a nonsignificant trend towards mortality reduction [HR 0.76, 95% CI (0.54-1.07)]. Statins [HR 0.96, 95% CI (0.77-1.19)] and aspirin [HR 0.87, 95% CI (0.55-1.38)] showed no significant mortality benefit. Bayesian probability ranks favoured beta-blockers as the most effective treatment for TTC mortality prevention. Conclusion: This review highlights the modest efficacy of secondary prevention medications in the management of TTC, as ACE or ARBs, beta-blockers, aspirin, and statins failed to demonstrate comparative mortality benefit. Randomized controlled trials are needed to confirm efficacy of pharmacotherapy in this vulnerable patient cohort.
