摘　　要：目的:探讨WI技术评价高血压患者左心室收缩功能和颈动脉血管的临床应用价值。方法:对56例高血压患者和50例健康志愿者采用高频线阵探头对颈动脉进行检测,应用echo-doppler系统测量颈动脉血流速度和直径变化,计算WI值(W1、W2和NA)、硬化参数(β)、弹性系数(Ep)、顺应性(AC)、增大指数(AI)和脉搏波传导速度(PWVβ、PWV-WI),比较高血压组与对照组各参数值的差异。结果:高血压组与正常对照组相比较W1和W2增高,差异有统计学意义(P<0.05);高血压组β、Ep、PWVβ及PWV-WI较正常对照组增高,AC降低,且差异均有显著性意义(P<0.05)。结论:WI技术能客观准确综合地反映高血压患者左心室收缩功能和血管弹性改变,高血压患者左心整体收缩功能高于健康成人。Objective：To study the clinical value of evaluating left ventricular systolic function and carotid artery in hypertension patients with wave intensity （WI） technology. Methods： A total of 106 cases were divided into two groups including hypertension group （56 cases） and normal volunteer group （50 cases）. Changes of blood flow velocity and diameter of carotid artery were measured by echo-Doppler system with high frequency array probe,the WI values （W1 ,W2 and NA ） as well as the parameters of arterial stiffness （β）, elasticity coefficient （Ep）, （AC）, （AI） and pulse wave transit velocity （PWVβ,PWV-WI） were calculated. The differences of all the parameters in hypertension and volunteers group were compared. Results：Compared with the normal volunteers,values of W1,W2 were significantly higher in hypertension group （P 〈0.05） ;β,Ep,PWVβ and PWV-WI were also higher with significant statistical differences （P〈0.05）. AC value was significantly reduced in hypertension group （P〈0.05）. Conclusion：WI technology can assess the left ventricular systolic function and reflect the vascular elasticity changes of hypertension patients accurately and objectively, showing that the global left ventricular systolic function in hypertension patiepts was higher than that of normal healthy adults.
