Investigating Thromboxane Function in Women With Endometriosis

The Role of Thomboxane A2 and it's Receptor in Vascular Regulation in Women With Endometriosis

Phase 4 Interventional Penn State University · NCT05962034

This study is testing whether taking aspirin can help women with endometriosis have better blood flow and pain responses compared to healthy women.

What this trial studies

This clinical trial aims to compare neurovascular regulation between women with endometriosis and healthy women. Participants will take either aspirin or a placebo and undergo various tests, including hand grip exercises and cold pressor tests, to assess blood pressure and pain responses. The study will also evaluate platelet activity and the role of thromboxane A2 in endothelial dysfunction associated with endometriosis. By analyzing these factors, researchers hope to uncover differences in cardiovascular responses between the two groups.

Who should consider this trial

Good fit: Ideal candidates for this study are women aged 18-45, with or without a diagnosis of endometriosis.

Not a fit: Patients who are currently pregnant, breastfeeding, or have existing cardiovascular diseases may 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 endometriosis.

How similar studies have performed: While there is existing research on endometriosis and cardiovascular health, this specific investigation into thromboxane function is relatively novel.
