Detailed Description
Existing predictive tools for preeclampsia (PE), including clinical characteristics, blood pressure, blood biomarkers, and uterine artery Doppler indices, have, at best, moderate predictive properties. While maternal symptoms often resolve with the delivery of the placenta, the burden of PE extends beyond pregnancy; afflicted women are at 3.1-fold increased odds of developing hypertension and 2.3-fold increased odds for cardiovascular disease later in life compared to women with uncomplicated pregnancies. Placental pathogenic changes associated with PE occur weeks to months before clinical manifestations develop, presenting a window of opportunity to identify early those women who will develop PE. The goal of the study investigators is to capitalize on this window and develop strategies for early prediction of PE.
As a composite measure of vascular health, measurement of arterial stiffness and wave reflection could represent a promising non-invasive tool for PE prediction. This multi-national 5-year observational prospective study aims to recruit 2400 participants across 8 sites in Canada, the US, and the UK. Participants will undergo 2 assessments, one in the first trimester (10 - 13 weeks gestation) and one in the second trimester (18 - 21 weeks gestation), which involve vascular measurements (arterial stiffness, blood pressure), blood sample collection, psychosocial and demographic questionnaires, and Uterine Artery Doppler imaging (only at second visit). Post-natal outcome measurements will be collected via medical charts for each participant 6-8 weeks post-partum. The primary objective of the study is to determine if, and to what extent, arterial stiffness and wave reflection parameters improve early prediction of PE beyond that achieved by currently available predictors in high-risk pregnancies.
