RESUMO
Objective :To analyze and explore influence of hyperuricemia (HUA ) on intracranial atherosclerosis . Methods : A total of 250 patients with non—cardiogenic cerebral infarction treated in our hospital from May 2014 to Jul 2016 were enrolled .Digital subtraction angiogrophy was performed in all patients .According to level of serum uric acid (SUA) ,patients were divided into HUA group (n＝84) and normal UA group (n＝166).Age ,percentages of hypertension ,coronary heart disease ,diabetes mellitus (DM) , hyperlipodemia ,smoking history and recurrence rate of cerebral infarction were compared between two groups ,and influencing factors of atherosclerotic intracranial artery stenosis were analyzed using single—and multi—factor regression analysis .Results : Compared with normal UA group ,there was significant rise in recurrence rate of ischemic stroke (25.30% vs.45.24%) in HUA group , P＝0.001. Single factor analysis indicated that hypertension ,DM and HUA were influencing factors for intracranial ar—tery stenosis , P＝0.001 all ;multi—factor regression analysis indicated that hypertension ,DM and HUA were inde—pendent risk factors for atherosclerotic intracranial artery stenosis (OR＝0. 960～4.957 , P＝0.001 all).Conclusion :Hyperuricemia is an independent risk factor for intracranial atherosclerotic stenosis .Monitor on HUA patients should be enhanced in clinic in order to prevent intracranial atherosclerosis .
