Angiogenesis biomarkers for the prediction of severe adverse outcomes in late-preterm preeclampsia.

Objectives: The optimal timing for delivery in non-severe late-preterm (34 + 0-36 + 6 weeks) preeclampsia (PE) is uncertain. It is attempted to reach term pregnancy safely but current clinical and analytical parameters fail to determine which cases will develop severe features that require preterm delivery. We aim to establish if angiogenic biomarkers may identify cases that would benefit from earlier delivery.
