Predicting preeclampsia early using arterial stiffness in high-risk pregnancies
Official title: Early Prediction of Preeclampsia Using arteriaL Stiffness in High-risk prEgnancies; a Multinational Study (PULSE)
Run by McGill University Health Centre/Research Institute of the McGill University Health Centre · NCT04783597 · Data updated 2026-11-12
This study is testing a new way to spot early signs of preeclampsia in high-risk pregnancies by measuring how stiff blood vessels are, along with other tests, to help improve care for moms and babies.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are pregnant women with singleton pregnancies who have at least one high-risk factor or two moderate-risk factors for preeclampsia.
✕Probably not a fit
Patients who are beyond 14 weeks gestation, have multiple pregnancies, or have a history of heart disease or infectious diseases may not benefit from this study.

What this trial studies
This observational study aims to improve early detection of preeclampsia (PE) in high-risk pregnancies by utilizing a non-invasive test to measure arterial stiffness, alongside blood biomarkers and ultrasound imaging. The study will recruit 2400 participants across multiple sites in Canada, the US, and the UK, conducting assessments in both the first and second trimesters of pregnancy. By identifying early signs of PE, the study seeks to develop strategies for better management and prevention of this serious condition. The findings could lead to significant advancements in maternal health care.
Why it matters
Potential benefit: If successful, this study could lead to earlier identification and management of preeclampsia, potentially reducing maternal and fetal morbidity and mortality.
How similar studies have gone: Other studies have shown promise in using non-invasive measures for predicting preeclampsia, but this approach is among the most comprehensive and multi-national efforts to date.
