title: [Analyses of carotid intima-media thickness and quantitative arterial stiffness in type 2 diabetes mellitus patients with follow-ups].
abstract: OBJECTIVE
  To explore the change pattern of carotid stiffness and its relationship between intima-media thickness (IMT) in type 2 diabetes mellitus (T2DM).
  
  
  METHODS
  Quantitative intima-media thickness (QIMT) and quantitative arterial stiffness (QAS) were performed on bilateral carotids of 72 T2DM patients in May 2009 and February 2011 separately. IMT, compliance coefficient (CC), α, β and pulse wave velocity (PWV) were measured. Their relationship was analyzed.
  
  
  RESULTS
  Comparing with ultrasound result in 2009, CC of bilateral carotids increased (left 0.9 ± 0.4 vs 1.1 ± 0.4, P = 0.016; right 1.1 ± 0.5 vs 1.2 ± 0.5, P = 0.012). IMT increased while α, β and PWV decreased (P > 0.05) in 2011. No correlation existed between carotid IMT and QAS parameters.
  
  
  CONCLUSIONS
  The glycemic, lipid and blood pressure controls decrease the carotid stiffness of patients with T2DM. Carotid IMT and stiffness.
