INTRODUCTION: Tissue Factor Pathway Inhibitor (TFPI) is a part of the extrinsic coagulation pathway, and highly expressed in the placenta. We aimed to assess its potential as a preeclampsia biomarker. METHODS: Maternal plasma was prospectively collected at 36 weeks' gestation. Circulating TFPI was measured in a nested case-control group (39 women who developed preeclampsia, 98 controls), before being measured in a larger independent cohort along with Placental Growth Factor (PlGF; 41 who developed preeclampsia, 954 controls). Circulating TFPI was then measured in women with underlying vascular disease, and also assessed in the plasma and placentas from women with preterm preeclampsia (delive..
