Trial Outcomes & Findings for Peripheral Vascular Effects of Sulfhydryl-containing Antihypertensive Pharmacotherapy on Microvessels in Humans (NCT NCT03179163)

NCT ID: NCT03179163

Last Updated: 2024-02-28

Results Overview

This measurement is performed using a laser Doppler flow meter. The flow meter produces a non-invasive qualitative and dimensionless index of blood flow in blood vessels during the localized perfusion of the endothelium-dependent vasodilatory acetycholine in a dose response fashion. The results are the differences in the area under the curve units=(laser Doppler flux/MAP)\*logAch concentration

Participant Flow

All participants were recuited out of the Centre County region and had Stage II hypertension based on resting seated brachial blood pressure. Other than hypertension, all participants were clinically healthy.

SECONDARY outcome

Timeframe: 16 Weeks

Blood pressure is measured via brachial auscultation manually or with a critical care monitor. The peak blood pressure during a cardiac cycle when the heart contracts.
