NPPB and hydrops fetalis: In 164 patients (99% men) hospitalised for decompensated HF, Waldo and coworkers found that admission and discharge NT-proBNP (AUC 0.788 and AUC 0.834) had superior prognostic power for all-cause mortality within 90 days post-discharge, when compared with BNP (AUC 0.644, p < 0.01 and AUC 0.709, p < 0.01) [6].
