Objective To investigate the relationship of serum uric acid level with carotid atherosclerosis and intracranial stenosis in patients with cerebral ischemic stroke.Methods 186 patients checked by Color Doppler Flow Imaging (CDFI) and Transcranial Doppler (TCD) were enrolled.According to the degree of carotid intima-media thickness (IMT), patients were divided into normal group, and intima thicken group, the plaque shaping group and the vascular stenosis group.According to the degree of intracranial stenosis, patients were divided into stenosis group and nonstenosis group.The serum levels of uric acid (UA), triglycerides (TG), total cholesterol (TC), highdensity lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C) were detected.The relative factors for carotid atherosclerosis and intracranial stenosis were analyzed by multiple logistic regression analysis.Results Compared with normal group and intima thicken group, the percentage of patients with hypertension, coronary heart disease and serum TC level were increased in plaque shaping group and vascular stenosis group (P＜0.05 for all).With the increase of carotid IMT, serum UA level was also gradually increased (F=11.386, P =0.000).Logistic regression analysis showed that serum UA level was the independent risk factor for carotid atherosclerosis (OR=3.486, P=0.013).Among 186 patients, 43 cases (23.1％) had intracranial vascular stenosis.The UA level was higher in stenosis group than in non stenosis group (t=9.372, P=0.013).Logistic regression analysis showed that serum UA level were the independent risk factors for intracranial arterial stenosis (OR =1.914, P=0.022).Conclusions The occurrence of carotid atherosclerosis and intracranial stenosis are closely related with hyperuricemia in patients with cerebral ischemic stroke, which indicates serum uric acid level may reflect the degree of carotid artery atherosclerosis.
