Abstract
ABSTRACTBackground: Increased arterial stiffness is an independent cardiovascular risk factor in smokers or patients with diabetes mellitus and hypertension. Cardio-ankle vascular index (CAVI) is an index of arterial stiffness and atherosclerosis. One of the most important risk factors of the causes of atherosclerosis is dyslipidemia(DLP). However, there was a little research about which influence factors such as: hypertension, diabetes mellitus, and smoking could contribute to the atherosclerosis in the subjects withDLP. Methods: A total of 649 subjects with DLP (Male328/Female321) from Vascular Medicine of Peking University Shougang Hospital were examined, with a median age of 66 and 5–95 percentile range 47.0–83.5 years. Fasting plasma glucose (FPG), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), triglyceride (TG) were analyzed by colorimetric enzymatic assays with the use of an auto analyzer (HITACHI-7170, Hitachi, Tokyo, Japan).CAVI was measured by VS-1000 apparatus. Results: CAVI correlated significantly with age (p<0.001), Systolic (p<0.001) blood pressure(BP), Total cholesterol (p<0.001), LDL-cholesterol (p<0.001),Triglycerides (p<0.001) . There was no significant difference in CAVI between smokers and non-smokers (p = 0.08) and between statin-treated subjects than in those without statins (p = 0.247). CAVI was significantly higher in subjects with hypertension than in the normotensive group (p<0.001) and in mellitus subjects than in those without mellitus (p<0.001);however, CAVI values adjusted for age was higher only in hypertension than in the normotensive group (p<0.001). Conclusions: Our study demonstrated that CAVI value in DLP patients is not significantly affected by diabetes mellitus and smoking, but is increased by hypertension.
