| Outline of Final Research Achievements |
Endothelial dysfunction is observed in several cardiovascular diseases, where endothelium-dependent vasodilation is impaired by oxidative stress. Endothelial function of the brachial artery is useful to estimate future risk of cardiovascular events. The purpose of this study is to investigate the time-course of endothelial function during the perioperative period of moderate surgery, and factors affecting recovery of endothelial function. Endothelial function was evaluated by reactive hyperemia index (RHI), which is a ratio of reactive hyperemia-stimulated vasodilation to that measured without stimulation using the EndoPAT 2000. Endothelial function was suppressed just after surgery, which took a few days returning to control levels. Recovery of endothelial function was impaired by diabetes mellitus, obesity and hyperuricemia.
