Understanding blood flow changes in aging women

Early Neurovascular Adaptations in Aging Women

Early Phase 1 Interventional University of Missouri-Columbia · NCT06520982

This study is testing how different treatments affect blood flow in women aged 18 to 55 to better understand changes in their cardiovascular health as they age.

What this trial studies

This study aims to investigate early neurovascular adaptations in women aged 18 to 55, focusing on how the sympathetic nervous system influences blood flow as they age. Participants will receive various interventions, including norepinephrine, isoproterenol, acetylcholine, nitroprusside, and estrogen, to assess their effects on vascular function. The research seeks to enhance knowledge about the physiological changes that occur in aging women, which may have implications for their cardiovascular health.

Who should consider this trial

Good fit: Ideal candidates for this study are women assigned female at birth, aged 18 to 55, who do not have significant health issues.

Not a fit: Patients who are assigned male at birth, pregnant, or have chronic diseases or significant health risks may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding and management of cardiovascular health in aging women.

How similar studies have performed: While there is ongoing research in vascular adaptations, this specific focus on aging women and the sympathetic nervous system is relatively novel.
