应用二尖瓣环运动速度评价高血压患者左室舒张功能

Quantitative Assessment of Left Ventricular Diastolic Function in Hypertension by Mitral Annulus Velocity

目的:利用定量组织速度成像(QTVI)技术测定二尖瓣环运动速度并评价高血压患者左室舒张功能的价值。方法:观察我院30例接受彩色多普勒检查的高血压患者,选择年龄相匹配的正常组30例,分别对这两组获取心尖四腔、心尖两腔、心尖长轴图像,测定左室各壁运动速度Vs,Ve,Va值并计算Ve/Va比值,将两组结果作对比研究。结果:高血压组左室各壁Vs、Ve值及Ve/Va值均低于正常组(P<0.05),而Va值与正常组相比,差异无显著性意义(P>0.05)。结论:应用定量组织速度成像技术测定二尖瓣环运动速度能较准确的评价高血压患者的左室舒张功能。

Objectlve：To analyse mitral annulus velocity measured by quatitative tissue velocity imaging（QTVI） and to evaluate left ventricular function of hypertension. Methods：30 patients with hypertension were compared with 30 healthy subjects, examing Tissue Motion Velocity numbers （Vs, Ve, Va, Ve/Va） in different wall of left ventricular, than contrast and study the results. Results：Compared with healthy subjects, the patients with hypertention show lower Vs,Ve, Ve/Va ratio of all walls（P 〈0.05） ,and the Va was not significantly different between the two groups. （ P 〉 0.05 ）. Conclusion： The mitral annular velocity determined by QTVI can arrurately evaluate the left ventricular diastolic function in hypertension patients.
