Description Module

Brief Summary

The study tests the hypothesis that nitric oxide availability is changed in congestive heart failure with regard to the regulation of renal hemodynamics, renal sodium excretion and release of vasoactive hormones. The study tests these hypotheses by comparing the effects of systemic nitric oxide inhibition with L-NMMA in congestive heart failure patients with healthy subjects on renal hemodynamics, blood pressure and plasma levels of vasoactive hormones.

Detailed Description

The purpose of the study is to investigate the effects of systemic treatment with Ng-monomethyl-l-arginine in congestive heart failure and healthy controls on:

glomerular filtration rate and renal plasma flow
blood pressure and heart rate
plasma levels of vasoactive hormones
lithium clearance

The study is randomized and placebo controlled
