Objective: This study was undertaken to determine whether maternal serum concentration of the angiogenic factor vascular endothelial growth factor (VEGF) and its circulating antagonist, soluble fms-like tyrosine kinase 1 (sFlt-1), which have been implicated in the pathogenesis of preeclampsia (PE), are altered in pregnancies that subsequently develop PE and in those with established fetal growth restriction (FGR). Study design: Three groups of healthy pregnant women at 23 to 25 weeks of gestation were examined: group A (n = 42) with normal uterine artery Doppler waveforms, group B (n = 49) with abnormal uterine artery Doppler waveforms, and group C (n = 15) with abnormal Doppler results and established FGR. Comparisons between multiple groups were performed by using 1-way analysis of variance or Kruskal-Wallis test. Results: In group C, compared with group A, the median sFlt-1 was significantly higher (P < .0001) and VEGF was lower (P < .001). Group C included 3 women who had PE develop. In group B, 19 women had a normal outcome, 13 had PE develop, and 17 had FGR develop. There were no significant differences in sFlt-1 levels between any of the subgroups of group B and group A. Conclusion: Maternal serum concentration of sFlt-1 in pregnancies with FGR is increased but this increase is not evident in pregnancies with impaired placentation that subsequently had either FGR or PE develop.
