Aims
Low blood concentrations of the naturally occurring amino acid L‐homoarginine (L‐hArg) are related to impaired cardiovascular outcome and mortality in humans and animals. L‐hArg is a weak substrate of nitric oxide synthase and an inhibitor of arginases in vitro. The aim of our study was to obtain kinetic and dynamic data after oral L‐hArg supplementation.
Methods
In a double‐blind, randomized,...
Nitric oxide (NO) is a modulator of left ventricular hypertrophy (LVH) and myocardial relaxation. The impact of NO availability on development of LVH has never been demonstrated in humans. We tested the hypotheses that elevation of asymmetric dimethylarginine (ADMA) concentrations (biochemical marker of decreased NO generation), and impairment of vascular responsiveness to NO donor GTN, would each...
