NPPB and hydrops fetalis: Multivariate logistic regression analysis was used to identify independent risk factors for MACEs among in-hospital HF patients and showed that EMATc >13.8% (OR 6.578, 95% CI 1.931–22.416,P = 0.003), and BNP >811.5 pg/ml (OR 3.398, 95% CI 1.201–9.601,P = 0.021) were independent risk factors for MACEs (Table 4).
