Cardiac T1 mapping in non-ST-segment elevation myocardial infarction: temporal changes in myocardial fibrosis.
Article in Frontiers in cardiovascular medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT07617844 (Multimodal-MRI in Cardiovascular Diseases), which is not on this 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.

Abstract
Introduction: Cardiac magnetic resonance (CMR) imaging allows tracking of ongoing fibrosis modifications following myocardial infarction (MI). We evaluated temporal changes in late gadolinium enhancement (LGE) and extracellular volume fraction (ECV) within the MI culprit coronary artery and remote regions of the myocardium during the index ischemic event and follow-up in patients with NSTEMI. Methods: This prospective, single-center study included 30 patients with type 1 NSTEMI. It involved the evaluation of patients using coronary angiography, invasive coronary physiology, and biomarkers. CMR imaging was used to assess left ventricular (LV) volume, function, and myocardial fibrosis using LGE and ECV. These assessments were performed at baseline and repeated 6-10 months after MI. Results: At the 4-year post-MI follow-up, 27 patients survived [age 65 (58,74) years; 77% male], and LV mass, volume, and contractility remained unchanged between the baseline and follow-up measurements. Myocardial fibrosis assessed using LGE showed a decreasing trend at follow-up (9.4 ± 4.4% vs. 6.7 ± 4.4%; Conclusions: After NSTEMI, LGE decreased in the heart regions supplied by the culprit coronary arteries. However, the ECV measurements remained unchanged. Multivessel CAD was not associated with significant changes in myocardial fibrosis in the remote myocardium.
