Could a common pill protect new Moms' hearts after complicated pregnancies?
NCT ID NCT07041281
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether spironolactone, a blood pressure pill, can help women who had high blood pressure during pregnancy avoid long-term heart issues. About 200 women with overweight and recent hypertensive pregnancy will take the drug or a placebo daily for 12 weeks after delivery. Researchers will check blood pressure and heart structure nine months later to see if the drug makes a difference.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- spironolactone
- What this could lead to
- If it works, this could point toward a simple daily pill to help women with past hypertensive pregnancy avoid long-term high blood pressure and heart problems.
- What could go wrong
- This is a small, early-phase trial with only 204 participants, so results may not apply to everyone. Spironolactone can cause side effects like high potassium or kidney issues.
