心-踝血管指数与心血管危险因素的相关性研究

Correlation between cardio-ankle vascular index and cardiovascular risk factors

目的观察心-踝血管指数(cardio-ankle vascular index,CAVI)与心血管危险因素的相关性。方法健康成人137人(年龄46.4±0.9岁,其中男性61人、女性76人),受试者均于空腹或餐后至少2h测定CAVI和血压,并收集受试者年龄、身高和体重等其它基本信息。用线性回归来分析CAVI与年龄、性别、Body Mass Index(BMI)、血压的相关性。结果CAVI与年龄、性别、收缩压、舒张压和平均动脉压显著相关。校正混杂因素后,年龄和性别仍然与CAVI强烈相关。结论健康成人中,年龄和性别是影响CAVI的决定性因素。

Objective To observe the correlation between cardio-ankle vascular index （CAVI） and cardiovascular risk factors. Methods The subjects （ n = 137 ） were healthy adults （ aged 46.4 0.9, male 61 and female 76）. Fast and 2-hour postprandial CAVI and blood pressure were detected in the subjects,and other basic information of age, height and body weight were collected. The correlation between CAVI and age,sex,body mass index （BMI） or blood pressure was analysed by using linear regression. Results CAVI was correlated significantly to age, sex, systolic pressure, diastolic pressure and mean arterial pressure. After the correction of confounding factors CAVI was still correlated intensively to age and sex. Conclusion Age and sex are the decisive factors influencing on CAVI in healthy adults.
