Reducing the Risk of Chronic Hypertension and Improving Vascular Function Following Preeclampsia

Sponsored by Medical College of Wisconsin

About this study

The long-term goal of our work is to evaluate the effect of intensive postpartum blood pressure control on maternal cardiovascular health, risk of chronic hypertension, and reversal of vascular dysfunction generated by hypertensive disorders of pregnancy, thus attenuating the lifelong trajectory of cardiovascular disease risk.

The REPAIR trial is a multicenter randomized controlled trial of 618 postpartum patients with hypertensive disorders of pregnancy randomized to intensive blood pressure control versus usual care during the first 6 weeks postpartum. The intervention group will receive intensive blood pressure (BP) control with nifedipine extended-release initiation when BP is ≥ 140/90 mmHg. The active control group will receive usual care with nifedipine ER initiation when BP is ≥ 150/100. The study will take place at two clinical sites: Medical College of Wisconsin (MCW) and Northwestern University (NU). All participants will undergo BP monitoring, cardiovascular function assessment, and collection of cardiovascular biomarkers at baseline, 6 weeks, and 12 months postpartum. Specifically, cardiac function a…
