Abstract：Objective To evaluate the iPAB and STAF scoring systems for screening paroxysmal atrial fibrillation(PAF) in patients with acute ischemic stroke.Methods Totally 469 cases of acute ischemic stroke were enrolled from October 2015 to October 2017 in the First People's Hospital of Yunnan Province.Among them,74 patients(15.8％) was diagnosed of PAF.National Institutes of Health Stroke Scale(NIHSS),left atrial dilatation and vascular etiology were assessed to calculate STAF score.Arrhythmia or antiarrhythmic history,left atrial diameter and brain natriuretic peptide (BNP) level were assessed to calculate iPAB score.Correlations among PAF,iPAB and STAF were analyzed by multivariate logistic regression.Diagnostic values of iPAB and STAF were analyzed by receiver operating characteristic(ROC) curve.Results Logistic regression analysis showed that age (odds ratio =1.039,95％ confidence interval:1.007-1.069),left atrial dilatation(odds ratio =1.208,95％ confidence interval:1.150-1.282),baseline NIHSS score (odds ratio =1.138,95％ confidence interval:1.091-1.203),lack of vascular etiology(odds ratio =0.167,95％ confidence interval:0.083-0.336),arrhythmia or antiarrhythmic history(odds ratio =1.165,95％ confidence interval:1.076-1.225) and elevated BNP level (odds ratio=1.076,95％ confidence interval:1.015-1.140) were risk factors of PAF(all P ＜0.01).ROC curve showed that STAF score≥ 5 (specificity =78.0％,sensitivity =76.0％) and iPAB score ≥4 (specificity =95.0％,sensitivity =82.0％) indicated high risk of PAF and the diagnostic efficiency of iPAB is significantly higher than that of STAF (P ＜ 0.05);the area under ROC curve of iPAB (0.93) was larger than that of STAF (0.81)(P ＜ 0.05).Conclusion Compared with STAF,iPAB scoring system is a simple,easy-to-use and effective method to predict the risk of PAF in patients with acute ischemic stroke.
