摘　　要：目的探讨应用定量组织速度成像（QTVI）技术评价尿毒症血液透析（HD）患者左心室功能变化的应用价值。方法A组，32例尿毒症HD患者，其中男性19例，女性13例，年龄39～79岁，平均年龄54．36岁；B组，35例健康志愿者，年龄、性别与A组相匹配，为对照组。用常规超声心动图和QTVI技术对其心脏形态结构和功能进行各节段参数测定。结果A组与B组间常规超声参数比较[左心室射血分数（EF）和短轴缩短率（FS）除外]差异有统计学意义（P〈0．05）；二尖瓣环各节段QTVI参数中舒张早期峰值速度（Ve）、Ve/Va（舒张末期峰值速度）值减低，与B组比较差异有统计学意义（P〈0．05）；Va明显增高，与B组比较差异有统计学意义（P〈0．05）。收缩期峰值速度（Vs）2组间比较差异无统计学意义（P〉0．05）。结论QTVI技术可以准确评价尿毒症HD患者左心室功能的变化。Objective To investigate the clinical value of quantitative tissue velocity imaging （QTVI） on left ventricular function in uremia hemodialysis（HD） patients. Methods Thirty-five normal subjects（control group） and 32 uremia HD patients（male 19, female 13, aged 39 - 79 years, mean age 54.36 years） were enrolled in this study. All of the patients were studied by echocardiogram and QTVI, the left ventricular structure parameters and the function parameters were measured and calculated. Results Compared with control group, the patients were showed significant differences in all parameters except ejection fraction （EF） and fractional shortening（FS）（P 〈 0.05）; and there were significant differences in early diastolic phase inflow E velocity（Ve）, A velocity （Va） and E/A ratio （Ve/Va）, especially in A velocity （P 〈 0.05）, but not in mitral annular systolic velocity （Vs）（P 〉 0.05） between 2 groups. Conclusion The changes of left ventricular function can be assessed accurately in uremia HD patients.
