Multivariate Cox regression confirmed that BNP (p < 0.001, HR = 1.009, CI = 1.006–1.012), creatinine (p = 0.016, HR = 1.247, CI = 1.042–1.492), and age (p = 0.013, HR = 1.027, CI = 1.006–1.049) were independent predictors of events in HF patients with BNP values <250 pg/mL at discharge. Here, NPPB is linked to hydrops fetalis.
