NPPA and hydrops fetalis: Patients who were identified as low-probability by CoDE-HF had a substantially lower rate of all-cause mortality at 30-days and 1 year compared with those who were identified as intermediate and high-probability for both BNP (30-day all-cause mortality: 0.8% vs. 5.1% and 11.5%; 1 year all-cause mortality: 7.0% vs. 21.9% and 34.6%, respectively) and MR-proANP (30-day all-cause mortality: 1.0% vs. 5.6% and 8.9%; 1 year all-cause mortality: 5.8% vs. 19.8% and 30.6%, respectively) (see Supplementary material online, Figure S11).
