Population
100 patients with atrial fibrillation

Cross-sectional
Key result
In patients with nonvalvular atrial fibrillation, a CHA2DS2-VASc score of 1 was associated with significantly greater left atrial remodeling, including increased maximum left atrial volume index (40.27 vs 26.79, p=0.002), compared to a score of 0.

May warrant caution in low-risk AF anticoagulation decisions; leaves open whether CHA2DS2-VASc better identifies remodeling than CHADS2.

The CHA2DS2-VASc score is better than the CHADS2 score at identifying left atrial remodeling in atrial fibrillation patients presenting with low stroke risk.
Li et al. (2013) conducted a cross-sectional in Nonvalvular atrial fibrillation (n=100). CHA2DS2-VASc score of 1 vs. CHA2DS2-VASc score of 0 was evaluated on Maximum left atrial volume index (LAVImax) (p=0.002). In patients with nonvalvular atrial fibrillation, a CHA2DS2-VASc score of 1 was associated with significantly greater left atrial remodeling, including increased maximum left atrial volume index (40.27 vs 26.79, p=0.002), compared to a score of 0.
