摘　　要：目的应用QAS技术初步探讨高血压对老年患者心脏与血管结构、功能受损的影响权重。方法分别检测、计算老年性高血压组(163例)与对照组(155例)的心脏结构、功能和颈动脉弹性参数,并进行2组间比较,运用ROC分析法评价各指标鉴别高血压患者心血管功能结构改变的效能。结果高血压组室间隔厚度、左室后壁厚度、E/e、Tei指数高于对照组,差异有统计学意义(P<0.05);高血压组血管弹性参数PWVβ和β高于对照组,差异有统计学意义(P<0.05)。ROC评价显示左室后壁厚度、Tei指数、和PWVβ的ROC曲线下面积分别为0.85、0.84、0.78,曲线下面积组间非参数检验差异有统计学意义(P<0.05)。结论高血压是血管硬化和心脏功能障碍的等危因素,老年高血压患者血管硬化和心功能障碍同步。Objective To cvaiuate the arterial stiffness in patients with hypertension by using Quality Arterial Stiffness （QAS） technology. Methods In the group of paticnts wich gerontal hypertension （n=167） and control group （n：165）, the parameters of arterial stiffness and Cardiac function were measured and calculated. The results were compared. Moreover, ROC curves were applied to analyze the efficacy of parameters. Results Thickness of ventricular wan, E/e, and Tel index of hypertension group were significantly higher than those of control group（P〈0. 05） In hypertension group, the parameters of arterial stiffness including PWVβ and β were significantly higher than those of control group （P〈0.05）. The area under ROC curve was 0. 85,0. 84 and 0. 78 corresponding to posterior wall of left ventricle, Tei index and PWVβ. Conclusions Hypertension contributes equivalently to arterial stiffness and Cardiac dysfunction in old people.
