NPPB and hydrops fetalis: For patients with a LVEF greater than or equal to 30% (≥30%; n = 65) the diagnostic performance of PTT for the inclusion of HF [NT-proBNP > 600 ng/L (>300 ng/L if BMI > 35 kg/m2)] amounts to an AUC of 0.62 (CI 0.48–0.76, P = 0.05) and for nPTT to an AUC of 0.77 (CI 0.65–0.89, P < 0.001) with a specificity of 58% and a sensitivity of 69% for a PTT > 7.1 s, and a specificity of 70% and a sensitivity of 75% for a nPTT > 475 (see Supplementary material online, Figures S7A and B).
