NPPB and hydrops fetalis: Similar results were obtained when patients were divided into tertiles according to GWTG-HF risk score (1st, <35 points; 2nd, 35–42 points; and 3rd, ≥43 points) and NT-proBNP (1st, <2627 pg/mL; 2nd, 2627–7431 pg/mL; and 3rd, ≥7432 pg/mL, all p for trend < 0.001; Figure 1 and Figure 2).
