Plasma nitrite flux predicts exercise performance in peripheral arterial disease after 3 months of exercise training

Open access

Abstract

Plasma nitrite is a major oxidation product of nitric oxide. It has also recently been suggested to perform an endocrine-like function as a nitric oxide donor in hypoxic tissues, allowing vasodilation. Exercise performance is limited in peripheral arterial disease because of an inadequate blood supply to working tissues. We hypothesized that exercise training in peripheral arterial disease subjects will improve "plasma nitrite flux" and endothelial function, to accompany increased exercise performance. Peripheral arterial disease subjects were tested at baseline and after 3 months supervised or home exercise training. Venous blood (arm) was drawn at rest and 10 min after a maximal graded treadmill test. Samples were added to heparin and centrifuged and plasma was snap-frozen for analysis by reductive chemiluminescence. Brachial artery endothelial function was measured in response to a hyperemic stimulus (flow-mediated dilation). At 3 months the peripheral arterial disease-supervised exercise group showed increases in claudication onset pain time (+138 s, p< or =0.05), peak walking time (+260 s, p< or =0.01), VO(2peak) (1.3 ml/kg/min, p< or =0.05), brachial artery flow-mediated dilation (+2%, p< or =0.05), and plasma nitrite flux (+33% p< or =0.05). There were no changes in the peripheral arterial disease-home exercise group. The change in plasma nitrite flux predicted the change in claudication onset pain (r(2)=0.59, p< or =0.01). These findings suggest that changes in plasma nitrite are related to endothelial function and predict exercise performance in peripheral arterial disease.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Plasma nitrite concentration is positively associated with exercise capacity in humans.

    “Indeed, several studies have reported that plasma [nitrite] is positively associated with exercise capacity in humans [26–29].”

    From Dietary Nitrate Supplementation and Exercise Performance (2014) · cites this paper as [26]

  • Plasma nitrite flux predicts the time to claudication onset pain reflecting exercise performance ability.

    “the authors found that plasma nitrite flux predicted the time to claudication onset pain reflecting exercise performance ability [174].”

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.
