Abstract: Objective To explore the predictive value of CHA2DS2-VASc score combined with left atrial diameter for the risk of stroke in patients with non-valvular atrial fibrillation (NVAF).Methods A total of 230 patients with NVAF were selected. CHA2DS2-VASc score was calculated for each patient by the clinical history and auxiliary examination. All patients were followed up for one year after discharging from hospital, and the follow-up visit would be finished if patients suffered from stroke or followed up for one year. The patients were divided into stroke group and non-stroke group according to the follow-up results.Results The CHA2DS2-VASc score and left atrial diameter in the stroke group were higher than those of non-stroke group. The area under the ROC curve of CHA2DS2-VASc score, left atrial diameter and CHA2DS2-VASc score combined with left atrial diameter to predict the happening of stroke in patients with NVAF were respectively 0.789,0.753 and 0.835. There were significant difference in area under the ROC curve among CHA2DS2-VASc score, left atrial diameter and CHA2DS2-VASc score combined with left atrial diameter(P<0.01).Conclusion The predictive value of CHA2DS2-VASc score combined with left atrial diameter is higher for the occurrence of stroke in patients with NVAF.

Key words: stroke, atrial fibrillation, CHA2DS2-VASc score, left atrial diameter
