Risk factors and association between cardio-ankle vascular index and carotid atherosclerosis in the patients with type 2 diabetes mellitus / 中国综合临床

ABSTRACT

ObjectiveTo study the association between cardio-ankle vascular index (CAVI) and carotid atherosclerosis as well as the risk factors in patients with type 2 diabetes mellitus.MethodsSixty type2 diabetic patients and 60 non-diabetic patients at the same hospitalization period were selected.The clinical features,laboratory test results such as free blood glucose ( FBG),blood lipids and other biochemical markers were recorded.Carotid intima-media thickness (IMT) and CAVI were measured.The relationship between CAVI and carotid atherosclerosis were analyzed; a multivariate linear regression analysis was performed between CAVI and risk factors of type 2 diabetes mellitus.ResultsThe body mass index,triglycerides,FBG,HbA1 c,IMT,the incidence of carotid artery plaque and CAVI values of diabetic group were significantly higher than that of nondiabetic group.Difference between the two groups was statistically significant ( all P ＜ 0.05 ) ; CAVI and carotid IMT was significantly correlated to each other( r =0.435,P ＜ 0.01 ) ; Multiple linear regression analysis showed that CAVI was significantly correlated to age (β =0.458,P ＜0.01 ),triglycerides (β =0.058,P =0.012),FBG (β =0.168,P =0.002) and HbAlc (β =0.228,P =0.003).ConclusionCAVI inpatients with diabetes was positively correlated with carotid IMT.Age,diabetes,triglycerides,FBG and HbAlc are independent risk factors for arterial stiffness.
