摘要 目的评价中心及外周动脉脉搏波速度测量的可重复性。方法分别对20名健康志愿者及10名有明显心血管危险因素的患者行颈-桡动脉脉搏波速度(CR-PWV)、颈-股动脉脉搏波速度(CF-PWV)、颈-足背动脉脉搏波速度(CD-PWV)的测量,2名操作者同一天分别对每位受试者连续测量3次,间隔24h再重复测量。结果操作者间CR-PWV、CF-PWV、CD-PWV测量的变异系数分别为4%、4%、5%,操作者内的变异系数分别为7%、4%、6%;操作者间及操作者内3段动脉PWV值差异无统计学意义(P>0.05);操作者间三段动脉PWV的组内相关系数(ICC)分别为0.75、0.93、0.49,操作者内三段动脉PWV的ICC分别为0.57、0.94、0.40;Bland-Altman显示操作者间三段动脉PWV测量的一致性好;CF-PWV与CR-PWV、CF-PWV与CD-PWV间呈线性相关,Pearson相关系数分别为0.448、0.611(P<0.05),CR-PWV与CD-PWV间无线性相关。结论自动PWV分析仪(CompliorSP,法国)测量脉搏波速度具有良好的重复性,适用于临床动脉硬化检测及干预试验。
