EP01.05: Adjusting the risk of pre‐eclampsia throughout pregnancy in a high‐risk population under aspirin prophylaxis

Methods This is a preliminary analysis of a cohort study including 125 singleton pregnancies at risk for PE before 37w (>1:100 at first trimester scan based on the FMF algorithm. ≥100mg of ASA was taken between 16-36w. Systolic (SBP), diastolic (DBP), mean arterial blood pressure (MAP) in mmHg and Z-score of the median pulsatility index of the uterine arteries in IU were evaluated at 20-236, 28-316 and 36386w. A ROC curve was used to evaluate the respective cutoffs and its correlation with PE development in patients who consistently screened positive for PE.
