Real-World Impact of Cardiac Rehabilitation Education and Therapy on Clinical Outcomes after Acute Myocardial Infarction: A Korean Cohort Analysis.
Article in Yonsei medical journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeCardiac rehabilitation (CR) is central to tertiary prevention after acute myocardial infarction (AMI), but the prognostic impact of different education and therapy patterns in Asian real world practice is uncertain. MATERIALS AND
methodsUsing Korean National Health Insurance Service claims (2018-2022), we identified patients aged ≥40 years hospitalized for AMI who underwent thrombolysis, percutaneous coronary intervention, or coronary artery bypass grafting. CR exposure was classified into six groups by structured education and the number of supervised therapy sessions, and outcomes over 2 years included all cause readmission, readmission and emergency room (ER) visits for MI or unstable angina (UA), all cause mortality, repeat revascularization, and stroke. Multivariable Cox models estimated adjusted hazard ratios (HRs) with 95% confidence intervals (CIs).
resultsAmong 92968 patients, 85.5% received no CR, 3.2% had education only, and 11.3% received any therapy. Education only participants had the lowest crude rates of mortality, cardiovascular readmission, and repeat revascularization. All CR exposed groups showed lower all cause mortality, with the greatest benefit in education plus ≥4 therapy sessions (HR 0.257, 95% CI 0.123-0.539) and ≥4 therapy sessions without education (HR 0.291, 95% CI 0.203-0.417). Education focused CR was additionally associated with lower cardiovascular readmission and repeat revascularization, whereas readmission and ER visits varied across therapy intensive groups.
conclusionIn this nationwide Korean AMI cohort, CR participation, especially with education, was associated with substantial mortality reduction, suggesting structured education as a pragmatic cornerstone of tertiary prevention, with supervised therapy providing incremental benefit when available.
