Abstract
Aim: We compared maternal serum and fetal cord blood proBNP levels in healthy pregnancies to those with intrauterine growth restriction (IUGR). Methods: Prospectively, maternal and cord blood samples at childbirth of 40 pregnant women with isolated IUGR and 40 healthy pregnant women were evaluated for ProBNP levels. Results: The mean serum ProBNP level was significantly higher in newborn cord blood with IUGR than in the control group (181.28 ± 145.37 vs. 91.41 ± 49.77 pg/mL, p = <0.01). Mean serum ProBNP level trended higher in women with IUGR compared to the controls, but was not statistically significant (124.21 ± 113.32 vs. 88.73 ± 85.18 pg/mL, p= >0.05). Conclusion: Third trimester mean proBNP in fetal cord blood are increased in IUGR fetuses at term birth compared to pregnancies with normal fetal growth.
