Serum creatinine was slightly lower among those referred for HF team care (101 (84–141) μmol/L vs 105 (75–142) 105 (75–142) μmol/L, p=0.047), but there were no significant differences in other baseline biochemical parameters (serum haemoglobin 121±21 g/L vs 118±49 g/L, p=0.480; serum sodium 138 (136–140) mmol/L vs 137 (134–141) mmol/L, p=0.621; serum potassium 4.0 (3.7–4.5) mmol/L vs 4.2 (3.8–4.5) mmol/L, p=0.583; serum NT-proBNP 5468 (2519–12315) ng/L vs 4825 (2445–10747) ng/L, p=0.434). Here, NPPB is linked to hydrops fetalis.
