摘要
The aim of the present study was to evaluate the effect of increased serum uric acid (UA) levels and their therapeutic reduction with allopurinol on endothelium-dependent dilation in subjects with a high cardiovascular (CV) risk but who were free from clinical CV disease. Patients with hyperuricemia had impaired flow-mediated dilation (FMD) compared with matched controls with normal UA levels and elevated CV risk. Three-month therapy with allopurinol improved FM in hyperuricemic subjects, showing an intrinsic negative effect of elevated UA levels on the arterial wall; conversely, FMD remained unchanged in controls, thus suggesting that the reduction of UA to less than a certain value does not affect endothelial function.
