NPPB and cardiac arrest: In univariate logistic analysis, cardiac arrest before admission, Killip class, heart rate, SBP, S2B, PCI or not, complete revascularization, NT-proBNP, LVEF, admission glucose as well as a SHR ≥ 1.25 significantly predicted in-hospital MACCEs (OR: 3.094, 95% CI: 1.794–5.337, P < 0.001, Table 3).
