Patients in the HF group had higher hs-CRP levels (13.61±4.34 vs 8.52±3.18 mg/L, P<0.001), higher CK-MB levels (249.94±55.81 vs 121.53±49.46 ng/mL, P<0.001), higher BNP levels (309.54±88.93 vs 196.81±79.35 pg/mL, P<0.001) (Figure 2A), and higher Cys C levels (2.60±0.69 vs 1.93±0.68 mg/L, P<0.001) (Figure 2B). This evidence concerns the gene NPPB and hydrops fetalis.
