Abstract:
AIM:To investigate the relationship between the fluctuation of blood glucose and the macrovascular complication of atherosclerosis (AS) in diabetic patients.METHODS:The individuals with different glucose tolerance were observed by continuous glucose monitoring for 3 days including the mean blood glucose (MBG) and its standard deviation (SD),mean amplitude of glycemic excursions (MAGE) and absolute means of daily differences (MODD).In addition,the intima-media thickness (IMT),intima smoothness as well as AS scores were measured respectively in bilateral common carotid arteries by means of high resolution B mode ultrasonography.RESULTS:The incidence of macrovascular complications in the subjects with impaired glucose tolerance (IGT) and newly diagnosed type 2 diabetes (T2DM) was significantly higher than those in the subjects with normal glucose tolerance (NGT),and a significantly difference between group IGT and T2DM was observed.The indexes detected by B mode ultrasonography were all increased gradually from NGT to IGT,then to newly diagnosed T2DM.The values of glycemic excursion were higher in IGT and T2DM group,especially in the subjects with diabetes than those in NGT group.In addition,multiple regression analysis showed that MAGE was significantly correlated with mean IMT and AS scores.CONCLUSION:Blood glucose fluctuation is associated with atherosclerosis.The patients with a larger range of blood glucose excursion have higher risks for developing atherosclerotic complications.The impaired glucose stability is a possible risk factor for atherosclerotic macroangiopathy in diabetes.
