Objective The aim of this study was to assess the association between CHA 2 DS 2 -VASc score and carotid plaques in patients with non-valvular atrial fibrillation (NVAF). Methods We conducted a retrospective study including 3,435 NVAF patients who underwent carotid ultrasound examinations from January 2015 to December 2017.We collected the clinical data on the medical records system. Chi-square trend test was used to analyze trends between the prevalence of carotid plaques with an increasing CHA 2 DS 2 -VASc score. Univariate and multivariate logistic regression was also used to assess the association between carotid plaques and CHA 2 DS 2 -VASc scores. The area under the receiver operating characteristic (ROC) curve (AUC) was used to determine the optimal cutoff points of different CHA 2 DS 2 -VASc scores in NVAF patients. Results NVAF patients with carotid plaques had higher CHA 2 DS 2 -VASc scores compared with patients who did not have carotid plaques (3.01±1.36 vs. 2.55±1.28, P < 0.05). In all participants, male participants and female participants, the prevalence of carotid plaques increased significantly as the CHA 2 DS 2 -VASc score increased ( P for trend < 0.001). Multivariate logistic regression analysis demonstrated that for each 1-point increase in the CHA 2 DS 2 -VASc score, there was an associated 37% increase in the prevalence of carotid plaques. ROC curve analysis revealed that a CHA 2 DS 2 -VASc score ≥ 2 in male patients (sensitivity, 44.67%; specificity, 75.64%; AUC, 0.639) or ≥ 3 in female patients (sensitivity, 47.24%; specificity, 72.40%; AUC, 0.634) were associated with carotid plaques. Conclusion The prevalence of carotid plaques in patients with NVAF was associated with the CHA 2 DS 2 -VASc score.
