NPPB and atrial fibrillation: Table 1 shows that there was no difference in gender, age, disease subtype, heart rate, systolic blood pressure, hemoglobin levels, CK-MB levels, Cr levels, 24 h urinary proteins, liver function, atrial fibrillation, and ECG between the two groups (all P > 0.05). But there were more patients with advanced NYHA class in the nonsurvival group (P < 0.001), as well as more patients with multiple involved organs (P = 0.02), higher log NT-proBNP levels (P = 0.002), and higher TnT levels (P = 0.01) (Table 1).
