To evaluate the possible associations between creatine kinase (CK), cardiac troponin T (cTnT), N-terminal-pro-B-type natriuretic peptide (NT-proBNP), and s100B levels in umbilical cord blood and nonstress test results, cord-blood gas analyses and Apgar scores.A total of 93 cesarean section deliveries after 34 + 0/7 gestational week (GW) were evaluated. The study (Mean age, weight, height, gestational age, and birth weight were comparable in type I and III NST groups. 1- and 5- minute Apgar, umbilical artery and vein pH values, and base deficiency were significantly lower in type III NST group compared to the type I NST group. The serum 100B (1616 ± 119 versus 533 ± 95 ng/L,Mean S100B, CK-MB, cTnT, and NT-proBNP were significantly higher in the study group compared to the control group. The serum 100B, CK-MB, cTnT, and proBNP levels were significantly elevated in the cord pH7.00 compared to pH = 7.00-7.15 group. The serum 100B and proBNP were significantly elevated in the cord pH = 7.00-7.15 compared to the pH7.15 group.
