Abstract: Objective:To observe the relationship between urinary albumin(UALB) and carotid atherosclerosis in cerebral infarction patients. Methods:One hundred patients with cerebral infarction were divided into 2 groups:UALB positive group(n=58) and UALB negative group(n=42).UALB excretion and ultrasonography for carotid artery were examined. Results:The common carotid artery intima media thickness,incidence rate of plaque were significantly higher in UALB positive group.The incidence rate of plaque was significantly higher when UALB exceeded the threshold of 60 mg/24 h(P0.05).The intima media thickness was positively related with the UALB,total cholesteral,and hemoglobin A1C,while the interior diameter was negatively with uric acid and UALB. Conclusions:High incidence of carotid atherosclerosis is happened in patients with positive UALB,especially when patients with UALB60 mg/24 h.
