摘　　要：目的:观察心脏-脚踝血管指数(CAVI)在正常人与患有心血管相关疾病人群之间的差异及与性别、年龄的关系,以更好的评价CAVI的临床应用价值。方法:对187人进行CAVI检测,观察CAVI在不同人群组之间的差异、与性别年龄的关系;通过对部分受检者进行复测,评价CAVI指标的稳定性。结果:CAVI指标在正常人与冠心病、高血压及其他疾病的人群之间有显著差异,但采用偏相关统计方法,在控制年龄因素的情况下,正常人组与各患病组之间无显著差异;CAVI检测值与性别无相关性,但与年龄呈较强的正相关;同一受检者两次检测的CAVI值之差在0.3以下,前后两组数据具有强相关。结论:CAVI与年龄呈正相关,与性别无关,临床检测值较为稳定。Objective：To investigate the difference of CAVI （ Cardio - Ankle Vascular Index） in the healthy people and the persons suffering from different cardiovascular diseases, and the correlation of CAVI to gender and age for better evaluating the clinical value of CAVI. Methods： 187 subjects were made the CAVI examination. We observed the difference of CAVI in the different groups and the correlation of CAVI to gender and age, moreover, we checked up the stability of CAVI through counterchecking part subjects. Results： There is a significant difference for CAVI in the different groups, but partial correlation analysis revealed that there is no difference in the different groups controlling the age factor. CAVI have strongly positive correlation with age, while gender is not rele- vant. The difference of twice CAVI value is under 0.3 for the same subject, and the twice data of CAVI have significant correlation. Conclusions： CAVI has strongly positive correlation with age, while gender is not relevant. And the value of CAVI is stable in clinical.
