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。
Objective: To assess the value of mitral annulus velocity and to evaluate left ventricular diastolic function in patients with hypertension by quantitative tissue velocity imaging (QTVI). Methods: Thirty cases of hypertensive patients undergoing color Doppler echocardiography were selected. Thirty patients in the normal age group were selected. The apical four-chamber, apical two-chamber, and apex long-axis images were obtained and the left ventricular Each wall velocity Vs, Ve, Va value and calculate Ve / Va ratio, the two groups of results for comparative study. Results: The values of Vs, Ve and Ve / Va in left ventricular wall of hypertension group were lower than those of normal group (P <0.05). There was no significant difference between Va group and normal group (P> 0.05). Conclusion: The quantitative assessment of mitral annulus velocity using quantitative tissue velocity imaging can be used to evaluate LV diastolic function more accurately.
