Interaction of Apelin and Angiotensin in the Human Forearm Circulation

NCT00901888 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 12

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.

Angiotensin has a powerful ability to cause blood vessels constrict and reduces their diameter. One of the actions of apelin is to cause blood vessels to relax and the investigators specifically wish test the hypothesis that apelin will cause blood vessels constricted by angiotensin II to relax.

Conditions

Interventions

DRUG

Apelin infusion

Infusion of up to 10picmol/min will be administered intra-arterially to induce vasoconstriction. Thereafter infusions of apelin (0.1, 1.0, 3.0nmol/min) will be given for 6mins each. During the same study, sodium nitroprusside will given (1.0, 2.0, 4.0 microg/min) for 6mins.

DRUG

Sodium nitroprusside infusion

Infusion of up to 150-600picmol/min will be administered intra-arterially to induce vasoconstriction. Thereafter infusions of apelin (0.1, 1.0, 3.0nmol/min) will be given for 6mins each. During the same study, sodium nitroprusside will given (1.0, 2.0, 4.0 microg/min) for 6mins.
