Predictive Effect of Atypical Right Bundle-Branch Block on In-Hospital Sudden Cardiac Death and Cardiac Rupture and Long-Term Prognosis in Patients With Acute Myocardial Infarction Who Underwent Percutaneous Coronary Intervention.
Article in Journal of the American Heart Association, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundA study was conducted to explore the predictive effect of atypical right bundle-branch blocks (ARBBB) on in-hospital sudden cardiac death (SCD), cardiac rupture (CR), and long-term prognosis in patients with acute myocardial infarction undergoing percutaneous coronary intervention with a drug-eluting stent. METHODS AND
resultsA total of 13 886 patients with first-episode acute myocardial infarction who underwent percutaneous coronary intervention with a drug-eluting stent at 3 centers from January 2017 to January 2022 were included in this retrospective study. Patients were categorized into 4 groups: ARBBB (n=348), typical right BBB (n=374), left BBB (n=366), and non-BBB (n=12 798). The primary end points were in-hospital SCD and CR, the secondary end points were 2-year major adverse cardiovascular and cerebrovascular events. During the in-hospital observation period, 334 patients (2.4%) experienced SCD, with 98 (0.7%) attributed to CR. The incidences of in-hospital SCD and CR in the group with ARBBB were significantly higher than those in the other 3 groups (ARBBB versus left BBB versus typical right BBB versus non-BBB: SCD, 10.6% versus 5.7% versus 4.3% versus 2.0%,
conclusionsARBBB is a predictor of in-hospital SCD, CR, and 2-year major adverse cardiovascular and cerebrovascular events in patients with first-episode acute myocardial infarction undergoing percutaneous coronary intervention with a drug-eluting stent.
