Association Between Extracellular Volume Assessed by Cardiac MRI and New-Onset Atrial Fibrillation in Patients With ST-Segment Elevation Myocardial Infarction.
Article in Korean journal of radiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
objectiveAlthough left ventricular (LV) fibrosis has been strongly linked to atrial fibrillation (AF), its relationship with new-onset AF (NOAF) following ST-segment elevation myocardial infarction (STEMI) remains unclear. This study aimed to investigate the association between different extracellular volume (ECV) measurements in the LV and NOAF during acute-phase STEMI. MATERIALS AND
methodsThis retrospective study included 517 patients diagnosed with acute STEMI (440 males, 77 females; mean age, 57.2 ± 12.4 years). All patients underwent cardiac magnetic resonance (CMR) imaging with T1 mapping sequences during hospitalization. Blood samples were collected within 24 hours of the CMR examination. ECV was assessed in three regions of the left ventricle: the non-myocardial infarction region (NMI-ECV), the myocardial infarction region (MI-ECV), and the entire myocardium (integral ECV). Multi-variable logistic regression was used to evaluate the associations between these ECV parameters and NOAF. Receiver operating characteristic (ROC) analysis was performed to assess the predictive value of ECV measurements, both alone and in combination with two conventional risk factors-N-terminal pro-B-type natriuretic peptide and infarct-related artery (right coronary artery).
resultsDuring hospitalization, 40 (7.7%) patients developed NOAF. After adjusting for confounding factors, including left atrial strain, MI-ECV, NMI-ECV, and integral ECV were independently associated with NOAF. The area under the ROC curve for predicting NOAF was 0.702 (95% confidence interval: 0.615-0.789), 0.625 (0.531-0.719), and 0.712 (0.627-0.798) for MI-ECV, NMI-ECV, and integral ECV, respectively. The addition of integral ECV and MI-ECV to conventional factors significantly improved the predictive performance for NOAF.
conclusionECV measured using CMR was independently and significantly associated with NOAF occurrence in acute-phase STEMI. Incorporating ECV into risk assessment models could significantly improve NOAF prediction.
