NPPB and atrial fibrillation: Compared with patients without AF, AF patients showed significantly higher left ventricular end systolic dimension (LVESD) (47.44 ± 4.55 vs 45.35 ± 4.51 mm, P<0.05), LAD (40.89 ± 6.37 vs 32.60 ± 3.46 mm, P<0.01), and NT-proBNP levels (290.36 ± 172.13 vs 194.90 ± 215.40 pg/ml, P<0.05).
