NPPB and atrial fibrillation: Compared with hs-cTNT normal group, hs-cTNT abnormal group were elder (68.3 ± 11.6 vs. 63.8 ± 10.6, P = 0.001); more likely to be suffered with atrial fibrillation (AF) (41.3% vs. 17.8%, P < 0.001) and with higher level of NT-proBNP concentration (752.0 [343.8–1345.5] vs. 249.0 [104.0–541.0], P < 0.001).
