Background: Inflammation has been implicated in the progressive exacerbation of valvular atrial fibrillation (VAF) and thrombogenesis. This study aimed to analyze the association of systemic inflammation as measured by six indices with left atrial thrombus (LAT) in patients with VAF. Methods: This comparative cross-sectional analytical study included 434 patients with VAF. Logistic regression analysis was used to assess the predictive value of LAT using six inflammation indices: neutrophil-to-lymphocyte ratio, monocyte-to-lymphocyte ratio (MLR), white blood cell-to-mean platelet volume ratio, neutrophil-to-mean platelet volume ratio, systemic immune inflammation index, and systemic inflammation response index. Receiver operating characteristic curves were plotted, and the area under these curves (AUC) were calculated to evaluate the discriminative ability of the indices. Results: Transesophageal echocardiography revealed LAT in 143 (32.9%) patients. All six indices reflected a positive correlation with C-reactive protein levels. Multivariate logistic analysis revealed that these indices were independent predictors of LAT, and MLR appeared to perform best (odds ratio 12.006 [95% confidence interval (CI) 3.404–42.347]; P < 0.001; AUC 0.639 [95% CI 0.583–0.694]; P < 0.001). Conclusions: Selected inflammatory indices were significantly and independently associated with LAT among patients with VAF. [ABSTRACT FROM AUTHOR] |
