The Association Between Controllable Risk Factors Of Stroke And These Two Methods:cardio-ankle Vascular Index And Ankle Brachial Index

Background: the detection method of CAVI is simple, easy,economical and noninvasive. It has high sensitivity to the degree of atherosclerosis in early screening, and its application is gradually paid attention. ABI also has these advantages, although the sensitivity is poor,but a large number of literature confirmed that it has a close relationship with cerebral stroke. Both of them are particularly applicable in large-scale stroke screening work in the general population.Objective: To analyze the association between the Common controllable risk factors of stroke and cardiac ankle vascular index(CAVI)and ankle brachial index(ABI) in the general population.Methods: From January to December of 2014,those who had completed the health examination item: blood pressure,waistline,body mass index(BMI),blood lipids, glucose,leucocyte count,CAVI and ABI were qualified. Eventually 11 353 cases were included in this study.The cases were divided into the CAVI normal group(CAVI<9.0m/s) andthe CAVI increase group(CAVI≥9.0 m/s) according to the CAVI results,and divided into the ABI>0.9m/s group and the ABI ≤0.9 m/s group according to the ABI detection results. The results of above detection items were performed the general factor and binomial logistic statistical analysis.Results :(1) The BMI,waistline,systolic blood pressure,diastolic blood pressure,leucocyte count,total cholesterol,triglycerides,low-density lipoprotein and blood glucose levels had the statistically significant differences between the CAVI normal group and CAVI increase group(P<0.05).(2)The BMI,waistline,systolic blood pressure,diastolic blood pressure and leucocyte count had the statistically significant differences between the ABI>0.9m/s group and the ABI ≤0.9 m/s group(P<0.05).(3)The waist-line,systolic blood pressure,leucocyte count,triglycerides(TG) and blood glucose were the independent risk factors of CAVI;the gender and BMI were negatively correlated with CAVI(P<0.01).(4)The systolic blood pressure and leucocyte count were the independent risk factors of ABI;the BMI and diastolic blood pressure were negatively correlated with ABI(P<0.01).Conclusion: The waistline,systolic blood pressure,leucocyte count,TG and blood glucose are the independent risk factors for atherosclerosis.
