Event-free survival (all-cause death andre-hospitalization) of patients with HF and B-lines ≥ 30was shorter than that of patients with B-lines < 30 (p <0.0001) in 3 months10 and of patients with B-lines ≥15 in 6 months,11 and the presence of B-lines ≥ 30 wasa predictor of death with BNP > 700 (p = 0.002).10 Here, NPPB is linked to hydrops fetalis.
