ABSTRACT
Objective To investigate the association between arterial stiffness of the common carotid artery(CCA)and insulin resistance in hemodialysis patients. Methods Arterial stiffness index β of CCA was evaluated by an ultrasonic phase-lock Echo-tracking system in 80stable non-diabetic hemodialysis patients.Insulin resistance was detected by the homeostasis model assessment method(HOMA-IR).Plasma hemoglobin,serum albumin,total cholesterol,high density lipoprotein,low density lipoprotein,triglyceride,lipoprotein(a),ApoA1,ApoB,CRP,calcium,phosphorus and creatinine were determined by standard methods. Results The stiffness index β was 11.41±4.13 in patients with previous cardiovascular disease(CVD)and 9.75±3.63 in those without CVD(P<0.05).The stiffness index β was positively correlated with HOMA-IR(r=0.321,P<0.01),as well as with age(r=0.376,P<0.01),pulse pressure(r=0.267,P<0.05),and duration of hemodialysis(r=0.219,P<0.05).In stepwise multiple regression analysis,HOMA-IR(β=0.228,P<0.05)and age(β=0.308,P<0.01)were identified as significant independent variables for stiffness index β of CCA. Conclusions Insulin resistance is associated with aaefial stiffness in nondiabetic hemodialysis patients.The increased arterial stiffness may be the link between insulin resistance and cardiovascular morbidity as well as mortality in hemodialysis patients.
