The association between CHA2DS2-VASc score and aortic valve sclerosis

Antithrombotic therapy in atrial fibrillation is generally managed with the CHA2DS2-VASc score. Aortic valve sclerosis (AVS) is a focal thickening of the aortic valve without a restriction of motion. AVS is related to several cardiovascular risk factors. Our study was performed to evaluate whether the presence of AVS was associated with the CHA2DS2-VASc score.This cross-sectional, observational study comprised 411 patients with AVS grades 1-3 [AVS (+)] and 102 patients with AVS grade 0 [AVS (-)]. We compared CHA2DS2-VASc scores between the AVS (+) and AVS (-) groups.We determined that the AVS (+) group had a higher CHA2DS2-VASc score than the AVS (-) group [3 (0-8) vs 1 (0-4), p < 0.001) ].In our study, the CHA2DS2-VASc score was found to be higher in patients with AVS than in those without AVS. AVS may predict cardiovascular risk in the general population.
