Effects of high-salt intake on women after preeclampsia

Role of the Mineralocorticoid Receptor in Microvascular Endothelial Dysfunction After Preeclampsia

Early Phase 1 Interventional University of Iowa · NCT06749418

This study is testing how eating a lot of salt affects blood vessel health in women who had preeclampsia during pregnancy, to see if a medication can help improve their condition.

What this trial studies

This study investigates how high-salt intake affects vascular function in women who have experienced preeclampsia during pregnancy. It focuses on the role of mineralocorticoid receptors in the vascular system, which may contribute to increased cardiovascular disease risk in these women. Participants will include women aged 18-45 who are 12 weeks to 5 years postpartum, both those who had preeclampsia and those who did not. The intervention involves administering eplerenone to assess its effects on vascular responsiveness to salt. The study aims to clarify the mechanisms behind vascular dysfunction associated with a history of preeclampsia.

Who should consider this trial

Good fit: Ideal candidates are women aged 18-45 who are 12 weeks to 5 years postpartum, with a history of preeclampsia or a healthy pregnancy.

Not a fit: Patients with a history of hypertension, metabolic disease, or current pregnancy will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding and management of cardiovascular risks in women with a history of preeclampsia.

How similar studies have performed: While the association between preeclampsia and cardiovascular risk is established, this specific approach to understanding vascular dysfunction is novel and has not been extensively tested.
