Placental growth factor predicts time to delivery in women with signs or symptoms of early preterm preeclampsia: a prospective multicenter study

摘要

BACKGROUND: There is a robust association between altered angiogenic factor concentrations, which includes placental growth factor and clinically recognized preeclampsia. Alterations in concentrations of angiogenic factors precede the clinical onset of preeclampsia by several weeks. The temporal relationship between the measured angiogenic factors and the time to delivery in women with suspected preeclampsia at <35 weeks gestation, however, remains to be clarified.
