Combined Brain-Cardiac CT in Ischemic Stroke: Unveiling Atrial Markers Linked to Large Vessel Occlusion in AF Patients.
Article in European journal of neurology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundAtrial fibrillation (AF) increases the risk and severity of ischemic stroke, particularly in large vessel occlusion (LVO) cases. Atrial cardiomyopathy (AtCM) severity may explain why some AF patients suffer LVO while others develop distal cardioembolic strokes. This study aimed to investigate whether AtCM markers detected on acute brain-cardiac CT are associated with LVO in AF patients presenting with ischemic stroke.
methodsWe analyzed 619 ischemic stroke patients admitted to Dijon University Hospital from November 2018 to March 2021. The cohort was divided based on the presence of LVO. Cardiac CT assessed left atrium volume (LAV), left atrial thrombus, and epicardial adipose tissue. Patients were grouped by LVO status.
resultsOf the 248 patients with acute stroke and AF, 138 (56%) had LVO. LVO patients had higher NIHSS scores (11 vs. 3, p < 0.001) and more frequent use of IV thrombolysis (27.7% vs. 12.3%, p = 0.030). Cardiac CT showed higher LAV in LVO patients (112.0 ± 43.0 cm
conclusionsLarger LAV and female sex independently predict LVO in AF patients, highlighting AtCM's role in stroke pathophysiology. Further research is needed to explore prevention strategies for high-risk AF patients.
