Women at increased risk of preeclampsia are most
commonly identified by a personal or family history of an
HDP, chronic medical disease, and/or abnormal uterine
artery Doppler before 24 weeks’ gestation. Combining
clinical, biochemical, and/or ultrasonographic risk markers
may better identify women at increased preeclampsia risk
(see “Prediction”); however, no intervention trial has used
such an approach to evaluate preventative therapy
