Study Description
Brief Summary:
To determine the effects of whether increasing CNP concentrations slightly above normal will improve the functioning of blood vessels after the interruption in the flow of blood. In this study we are looking at the function of the blood vessels of the forearm, as a substitute for those in the heart

Condition or disease Intervention/treatment
Ischaemia-reperfusion (IR) Injury Drug: C-type natriuretic peptide (CNP) Drug: Saline Drug: Acetylcholine
