目的：：探讨高血压患者升主动脉前壁运动速度与左室重构的相关性。方法：入选研究对象为原发高血压患者100例及健康对照组50人，二维超声测量计算左室质量指数（LVMI）、相对室壁厚度（RWT），M超测量计算升主动脉扩张性（AD）及动脉僵硬度（ASI）应用QTVI技术获得升主动脉前壁运动速度曲线，测量收缩期峰值速度(Vs)、舒张早期峰值速度(Ve)及舒张晚期峰值速度(Va)。结果：1.高血压组升主动脉前壁运动速度Vs、Ve均较对照组减低（P均<0.05），Vs、Ve与ASI呈显著负相关，与ADC呈显著正相关(P均<0.01)。2.升主动脉前壁运动速度Vs、Ve均与RWT呈负相关（P<0.05），与LVMI呈显著负相关(P<0.01)。结论：高血压患者升主动脉前壁运动速度与左室重构紧密相关。

objective To investigate the reationship between Left ventricular remodeling and ascending aortic anterior wall motion ve-locity in Patients with Essential Hypertension .Methods:Study subjects were 100 hypertensive subjects and 50 normal controlled subjects. Left ventricular mass index(LVMI) and relative wall thickness(RWT ) were by using two dimensional ultrasound, Ascending aorta distensi-bility (AD)and aortic stiffness index( ASI)were checked through M type ultrasound . We examined aortic upper wall by using quantitative tissue velocity imaging (QTVI)and measure systolic velocities Vs,early diastolic velocities Ve,late diastolic velocities Va.Results1.Ob-tained by QTVI technique in hypertensive patients with anterior wall of ascending aorta velocity of Vs, Ve were lower than the control group (all P<0.05), is negatively related to Vs, Ve and ASI, and positively correlated with ADC (P<0.01).2 The anterior wall of ascending aorta velocity Vs, Ve were negatively correlated with RWT (P<0.05), was negatively correlated with LVMI (P<0.01)Conclusion Left ven-tricular remodeling and ascending aortic anterior wall motion velocity is closely related in patients with essential hypertension.
