Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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
