摘　　要：目的评价臂踝脉搏波速度测量的可靠性。方法由两名测量者对23名心血管疾病高危患者和7名健康受试者进行臂踝脉搏波速度的测量。测量分为两阶段,中间间隔2周,每一阶段在同一天上午(8:30～11:00)和下午(13:30～16:00)分别进行测量。结果重复测量方差分析显示,测量者间和测量者内(不同时间)臂踝脉搏波速度无显著性差异。心血管疾病高危患者测量者间和测量者内臂踝脉搏波速度的Pearson相关系数为0.925～0.992 (P<0.01),组内相关系数为0.924～0.992(P<0.01);健康受试者测量者间和测量者内臂踝脉搏波速度的Pearson相关系数为0.674～0.974(P<0.05),组内相关系数为0.672～0.973(P<0.05)。Bland-Altman图显示,测量者间和测量者内臂踝脉搏波速度有较好的一致性。结论在规范的测量条件下,测量者间和测量者内的臂踝脉搏波速度的重复性好。Objective To assess the reliability of brachial ankle pulse wave velocity （baPWV） measurement. Methods The baPWV measurement was performed in twenty-three patients at high risk for developing cardiovascu- lar disease and seven healthy people by two observers on two separate days in a two weeks interval, with two exams （.in the morning （8..30--11：00） and afternoon （13：30--16：00）] each day. Results No significant differences were observed by repeated measurement analysis of variance between-observer and within-observer, Pearson＇s correlation coefficients of patients between two observers and within-observer were 0, 925--0. 992 （ P〈0.01）, intra-class coeffi- cients were 0. 924--0. 992 （P〈0.01）. Pearson＇s correlation coefficients of healthy people between two observers and within-observer were 0. 674-- 0. 974 （P〈 0.05）, intra-class coefficients were 0. 672 -- 0. 973 （P〈 0.05）, Interobserver and intra-observer Bland-Ahman plots showed good reproducibility. Conclusion Under standardized measurement conditions, baPWV showed good inter-observer and intra-observer reproducibility.
