In multivariate analysis, both LAVi<sub>max</sub> and LASr emerged as independent indicators of LVAs (OR 0.85; 95% CI 0.80-0.90, <i>P</i><0.001) and (OR 1.15, 95% CI 1.02-1.29, <i>P</i> =0.021). ROC analysis demonstrated good predictive capacity for LA-LVAs, with an AUC of 0.733 (95% CI 0.650-0.794, <i>P</i> <0.001) for LAVi<sub>max</sub> and 0.839 (95% CI 0.779-0.898, <i>P</i> <0.001) for LASr.</p><p><strong>Conclusion: </strong>Automatic assessment of LAVi<sub>max</sub> and LASr presents a promising non-invasive modality for predicting the presence of LA-LVAs and evaluating significant atrial remodeling in NVAF patients. This approach holds potential for aiding in risk stratification and treatment decision-making, ultimately improving clinical outcomes in patients.</p>","PeriodicalId":14131,"journal":{"name":"International Journal of General Medicine","volume":null,"pages":null},"PeriodicalIF":2.1,"publicationDate":"2024-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11456279/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142380806","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
