Trial Outcomes & Findings for Mechanisms of Hypertension in Women With Polycystic Ovary Syndrome (NCT NCT04327934)

NCT ID: NCT04327934

Last Updated: 2024-02-02

Results Overview

forearm blood flow (ultrasound)/mean arterial pressure as a linear function of lower body negative pressure. This is an important measure of autonomic control of blood pressure. Indicating the the sensitivity of changes in vessel diameter in response to blood pooling (induced by lower body negative pressure).

Participant Flow

We will recruit subjects using flyers, our clinics, and social media. Dates 12/01/2017 - 04/29/2022; We were not able to reach recruit goals because our laboratory closed during Covid. When we reopened, we lost a one interested subject, and found greater challenges to recruit subjects.
