Effects of Prenatal Aspirin on Postpartum Vascular Health

Protective Mechanisms of Prenatal Aspirin Therapy on Maternal Vascular Dysfunction Following Preeclampsia

Early Phase 1 Interventional University of Iowa · NCT05653973

This study tests if taking low-dose aspirin during pregnancy helps improve blood vessel health after giving birth in women who had preeclampsia compared to those with normal pregnancies.

What this trial studies

This study investigates how low-dose aspirin therapy during pregnancy affects vascular function in women who have experienced preeclampsia. It focuses on understanding the mechanisms behind persistent vascular dysfunction postpartum by examining blood vessels in the skin. Participants will include women who had normal pregnancies and those who experienced preeclampsia, with varying use of low-dose aspirin. The study employs a minimally invasive technique to assess microvascular function.

Who should consider this trial

Good fit: Ideal candidates are women aged 18 years or older, between 12 weeks to 5 years postpartum, with a history of either normal pregnancies or preeclampsia.

Not a fit: Patients currently using daily aspirin or those with certain health conditions, such as chronic kidney disease or skin diseases, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved cardiovascular health outcomes for women who have had preeclampsia.

How similar studies have performed: While studies on low-dose aspirin in pregnancy are common, this specific investigation into postpartum vascular function is relatively novel.
