Abstract

NO is crucial for endothelial function and vascular health. Plasma nitrite (NO(2)(-)) is the main oxidation product of NO and has been shown to reflect changes in eNOS activity. We hypothesized that plasma NO(2)(-) response to physical exercise stress along with physiological endothelial function would be reduced with increasing severity of vascular disease. Subject groups were: (a) risk factors but no vascular disease (RF); (b) Type 2 diabetes with no vascular disease (DM); (c) diagnosed peripheral arterial disease (PAD); and (d) DM+PAD. Venous blood was drawn at rest and 10min following maximal exercise. Plasma samples were analyzed by reductive chemiluminescence. Brachial diameters were imaged prior to, during and following 5min of forearm occlusion (BAFMD). There were no differences in resting plasma NO(2)(-) or BA diameters between groups. The PAD groups had lower age adjusted BAFMD responses (p0.05). Within group analysis revealed an increase in NO(2)(-) in the RF group (+39.3%), no change in the DM (-15.51%), and a decrease in the PAD (-44.20%) and PAD+DM (-39.95%). This was maintained after adjusting for age and VO(2peak) (p0.05). DeltaNO(2)(-) and BAFMD were the strongest independent predictors of VO(2peak) in multivariate linear regression. These findings suggest DeltaNO(2)(-) discriminates severity of cardiovascular disease risk, is related to endothelial function and predicts exercise capacity.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
