title: [The relationship between hyperlipidemia and lower limb arterial disease in elderly diabetes patients].
abstract: OBJECTIVE
  To evaluate the correlation between hyperlipidemia and lower limb arterial disease in elderly diabetic patients with color Doppler ultrasonography.
  
  
  METHODS
  Two hundred and sixty elderly diabetic patients and 206 normal subjects were enrolled in the study. Doppler ultrasonographic manifestations of lower limb arterial disease, blood pressure and blood biochemistry parameters including fasting plasma glucose (FPG), postprandial plasma glucose (PPG), TC, TG, HLD-C, LDL-C, apoprotein B (apoB), very low density lipoprotein cholesterol (VLDL-C), apoprotein A1 (apoA1) and fibrinogen (Fb) were compared between the 2 groups.
  
  
  RESULTS
  (1) The blood biochemistry parameters, including the levels of FPG, PPG, TC, TG, VLDL-C, LDL-C, apoB and Fb were higher in diabetic patients than in normal subjects, while HDL-C was lower (all P < 0.05). (2) The thickness of intima-media (IMT) in the lower limb arterial disease group was significantly increased and the presence of arterial stenosis and wall plaques more in diabetic patients [IMT in 205 cases (78.85%), atherosclerotic plaque in 241 cases (92.69%), multivessel disease (more than 2 vessels) in 60 cases (23.08%) and arterial stenosis in 89 cases (34.23%)] than in normal subjects [IMT in 37 cases (17.96%), atherosclerotic plaque in 51 cases (24.76%), multivessel disease in 27 cases (13.11%) and arterial stenosis in 3 cases (0.01%)], all P < 0.01. (3) Regression analysis showed that lower limb arterial disease was correlated with high level of LDL-C and low level of HDL-C.
  
  
  CONCLUSIONS
  Arteriosclerotic plaque is one of the early manifestations in elderly diabetic patients and hyperlipidemia may provide the basis of its formation. Doppler ultrasonographic examination of lower limbarterial discloses the early arteriosclerotic changes of lower limb arterial disease in elderly patients and offers the basic data of indication for clinical treatment.
