Could a sleep hormone help heal damaged hearts in new moms?
NCT ID NCT07334197
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether adding melatonin (a natural sleep hormone) to standard heart failure treatment can improve heart function in women with peripartum cardiomyopathy, a rare heart condition that develops during or after pregnancy. 25 women will receive either melatonin, selenium, or a placebo for 3 months. The goal is to see if these supplements help the heart pump better and reduce inflammation.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Melatonin (10 mg daily) and Selenium (100 mcg daily)
- What this could lead to
- If it works, this could point toward a simple, low-cost addition to standard heart failure therapy for women with peripartum cardiomyopathy, potentially improving heart recovery.
- What could go wrong
- This is a very small, early-phase trial with only 25 participants. The results may not apply to all patients, and the benefits of melatonin for heart function are not yet proven.
