Prediction of adverse left ventricular remodeling by culprit lesion features in patients with LAD-related myocardial infarction.
Article in Scientific reports, 2025. 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
High-quality evidence regarding the associations between culprit lesion features and cardiac function after post-percutaneous coronary intervention (PCI) in ST-segment elevation acute myocardial infarction (STEMI) patients is still needed. Cardiac magnetic resonance (CMR) can be used to visually and quantitatively evaluate myocardial damage. The purpose of this study was to validate the ability of culprit lesion features to predict adverse left ventricular (LV) remodeling evaluated by CMR imaging in left anterior descending artery (LAD)-related STEMI. Eighty-two STEMI patients treated with primary PCI were included. LAD culprit lesion location (CLL) and preprocedural thrombolysis in myocardial infarction (TIMI) flow were obtained from coronary arteriography. All the subjects underwent acute and 4-month follow-up CMR examinations. CMR cine and late gadolinium enhancement (LGE) images were analyzed to evaluate LV function and myocardial infarct (MI) scar characteristics. The correlations between angiographic and CMR characteristics, and the predictive values of culprit lesion features for adverse LV remodeling calculated by CMR were evaluated. LAD-CLL was negatively correlated with infarct size (r = -0.41, p < 0.05). Compared with patients with microvascular obstruction (MVO) and transmural MI, LAD-CLL was statistically significantly longer in MVO absent (30.8 ± 9.6 mm vs. 25.6 ± 7.5 mm, p = 0.008) and non-transmural MI (30.6 ± 8.4 mm vs. 25.0 ± 7.8 mm, p = 0.001). Logistic regression analysis demonstrated that LAD-CLL [odds ratio (OR) = 0.837 (0.754-0.929), p = 0.001] and BMI [OR = 1.286 (1.065-1.554), p = 0.009) were independent predictors of adverse LV remodeling. Proximal-LAD culprit lesions were associated with severe myocardial injury, as evaluated by CMR. The LAD-CLL is a promising parameter for predicting adverse LV remodeling after MI.
