This study compared the effect of a 30-minute walk on brachial artery endothelial vasodilatation in kidney transplant (KT) recipients and healthy controls (HCs). Endothelial-dependent vasodilatation was measured by ultrasound before and after exercise. The HCs experienced a significant increase in vasodilatation after exercise 1 minute postocclusion when compared with the KT recipients (22% ± 13% vs 3% ± 4%; P < .05). Also, the HCs had a significantly higher vasodilatation from pretreadmill walk to post-treadmill walk (1 minute postocclusion) when compared with KT recipients (from 3% ± 6% to 22% ± 13% vs 1% ± 3% to 3% ± 4%; P < .05). This acute vasodilatory response observed in the HCs may be related to the immediate release of nitric oxide and the combined response to shear stress and exercise. The KT recipients had several coronary artery disease risk factors that may have adversely affected endothelial function. [ABSTRACT FROM AUTHOR] |
