Interaction of Apelin and Angiotensin in the Human Forearm Circulation

• Status: Completed
• Trial end date: 2010-04-01
• Target enrollment: 0
• Participant gender: All

Summary

The apelin-APJ system is a relatively new discovery. It has generated interest in part due to it's apparent ability to counteract the renin-angiotensin system, which is frequently overactive in many cardiovascular disease.

Apelin has the ability to cause blood vessels to relax, increasing their diameter and hence blood flow down the blood vessel. The researchers wish to investigate the hypothesis that an infusion of apelin will reduce the effects of angiotensin II, which is know to reduce the diameter of blood vessels.
