摘　　要：目的研究3种不同动脉弹性功能参数:脉搏波传导速度(PWV)、大小动脉弹性指数(C1和C2)、压力反射波增强指数(AI)之间的相关性及不一致性。方法选取门诊高血压患者1306例,其中610例同时测定C1和C2,428例同时测定AI与PWV,208例同时测定C1、C2与PWV,60例同时测定C1、C2、PWV与AI,采用单因素和多元逐步回归统计方法进行分析和比较。结果同一个体无论进行两种还是3种动脉弹性功能测定均显示,C1和PWV显著负相关,C1和C2显著正相关,AI与PWV、C1、C2之间无显著性相关。结论PWV、C1和C2反映动脉弹性功能状况较为一致;AI与PWV、C1和C2的一致性较差。Objective To study the correlation of three different indexes of arterial elastic function（PWV, C1 and C2, AI）. Methods 1306 out-patients with hypertension were recruited. Two or three arterial elastic function were measured at the same time. Large and small arterial elastic indexes（C1 and C2 ） ;pulse wave velocity（PWV）and augmentation index （AI） in 428 cases , C1 , Caand PWV（n=208）, C1 , Ca, PWV and AI（n=60）. Results C1 was negatively related to PWV and positively related with Ca. No correlation between AI and PWV, AI and C1 and C2 was found. Conclusion PWV, C1 and Ca are consistent for the arterial elastic function measurement. However, little relevance between AI and PWV, AI and C1 and Ca was shown.
