Incidence and In-Hospital Outcomes of Bradycardia or Atrioventricular Conduction Disorder in Patients With Type 2 Myocardial Infarction: A Nationwide Inpatient Analysis.
Article in Journal of arrhythmia, 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
Background: Type 2 myocardial infarction (T2MI), caused by an imbalance between oxygen supply and demand without significant coronary obstruction, is increasingly recognized yet remains underexplored, particularly regarding conduction abnormalities. Methods: We conducted a retrospective cohort study using the National Inpatient Sample from 2017 to 2022. Adult patients hospitalized with T2MI were identified by ICD-10-CM code. Bradycardia or atrioventricular (AV) conduction delay was defined using diagnostic codes for bradycardia and all degrees of AV block. We compared baseline characteristics, comorbidities, and causes of T2MI, and used multivariable logistic regression to evaluate associations with in-hospital mortality and cardiogenic shock. Results: Among 1 960 410 patients with T2MI, 118 025 (6.0%) had bradycardia or AV conduction delay. These patients were older, more often male, and had higher rates of hypertension, heart failure, chronic kidney disease, and diabetes. The pacemaker implantation was significantly more prevalent (8.7% vs. 0.3%, Conclusions: Bradycardia or AV conduction delay occurred in 6% of T2MI hospitalizations and was independently linked to worse in-hospital outcomes, underscoring the need for close monitoring in this population.
