Abstract
- Background: Propensity for lesion lateralization in atrial fibrillation-related cardiac embolic stroke (AF-stroke) remains controversial. In this study, we compared the hemispheric differences among patients with AF-stroke and identified factors associated with lesion laterality.<br />Methods: We retrospectively reviewed patients with acute AF-stroke admitted from January, 2017 to March, 2022. Patients were grouped based on whether lesions were right or left hemispheric in the anterior circulation territory, based on diffusion-weighted imaging. Factors associated with right-side propensity were analyzed.<br />Results: Among 385 patients, the mean age was 74±11 years and 52.5 % were male. Right and left hemispheric lesions were observed in 189 (49.1 %) and 196 (50.9%) patients, respectively. In the multivariate analysis, enlarged left atrium (LA) (adjusted odds ratio [aOR]=1.03, 95% confidential interval [CI], 1.007-1.061; p=0.013) and single confluent lesion pattern (aOR= 1.55, 95% CI, 1.012-2.381; p=0.044) were associated with right hemispheric lesions.<br />Conclusions: Enlarged LA and single confluent lesion pattern were strongly related to right-sided propensity in patients with AF-stroke.<br />Competing Interests: Declaration of Competing Interest None.<br /> (Copyright © 2023 Elsevier Inc.
