RÉSUMÉ
Objective To investigate the relationship between impaired glucose tolerance(IGT)and carotid atheromatous plague in patients with acute cerebral infarction and analyze the risk factors for plaque formation.Methods The 326 patients hospitalized in our department for acute cerebral infarction were divided into diabetes mellitus(DM)group,IGT group and normal glucose tolerance (NGT)group.The clinical features,biochemical indices and results of Doppler ultrasound examination of the carotid artery were compared between the 3 groups.Results The body mass index(BMI),total cholesterol(TC),and low-density lipoprotein cholesterol(LDL-C)of IGT group were markedly higher than those in NGT group(P<0.05).Both the IGT and DM group showed significantly increased carotid intimal-medial thickness,plaque detection rate and the incidence of carotid scleratheroma in comparison with the NGT group(P<0.05).Logistic regressive analysis identified age,TC,LDL-C and 2-h postprandial serum glucose as the independent risk factors for carotid scleratheroma.Conclusion In patients with acute cerebral infarction,those having impaired glucose often show obvious carotid scleratheroma with a severity similar to that in the DM patients.
