Summary

This trial aims to study the impact of closely monitoring and controlling blood pressure after giving birth on the overall heart health of mothers. The goal is to reduce the risk of developing long-term high blood pressure and

Who is the study for?

This trial is for women aged 18-50 who have had high blood pressure or preeclampsia during pregnancy, can communicate in English or Spanish, and are within the first three days after giving birth. It's not for those with pre-pregnancy hypertension or diabetes, planning to transfer hospitals postpartum, allergic to nifedipine, or unable to consent.

What is being tested?

The study tests whether intensive blood pressure control using NIFEdipine ER after childbirth can improve heart health, lower the risk of long-term high blood pressure, and reverse vascular damage caused by hypertensive disorders during pregnancy.

What are the potential side effects?

NIFEdipine ER may cause side effects such as headache, swelling of the ankles/feet (fluid retention), dizziness/lightheadedness due to low blood pressure, flushing (warmth/redness/itchy skin), fatigue and nausea.

Active Control

Group I: REPAIR ARMExperimental Treatment1 Intervention

Intensive postpartum blood pressure control with nifedipine ER initiation at systolic blood pressure (SBP) ≥140 mmHg or diastolic blood pressure (DBP) ≥90 mmHg and maintaining blood pressure \<140/90 mmHg during the first 6 weeks postpartum.

Group II: CONTROL ARMActive Control1 Intervention
