摘　　要：目的探讨超声二维斑点追踪显像技术(STI)在评价慢性肾功能不全患者(CRF)左室功能中的应用价值。方法获取正常对照组(28例)、CRF组(50例)标准心尖四腔、三腔、两腔和短轴二尖瓣、乳头肌、心尖水平图像;分别测量和比较CRF组与对照组各节段的纵向、径向和圆周的收缩期峰值应变。结果对照组左室长轴纵向应变在心尖部最大(P<0.05);短轴径向应变差异无统计学意义;圆周应变在前间隔和后间隔基底及中间段高于同水平心尖段(P<0.05)。与对照组比较,CRF组纵向、短轴径向及圆周应变值均降低(P<0.05)。结论斑点成像技术能够较好的评价CRF患者左室功能。Objective To research the value of ultrasonic two-dimensional speckles tracing imaging technology （STI） on left ventricle function of chronic kidney failure （CRF） patients. Methods The standard images of apical four-, three-, twochamber and horizontal images of short axis mitral valve, columnae papillares and apex eordis were collected from the healthy suhjects （n =28） and CRF patients （n =50）. The flexural, radial and circumference contraction period peak value deformations were measured and contrasted respectively in both groups. Results In the healthy subjects, the left chamber long axis flexural deformations in apex cordis was the biggest （ P 〈 0.05 ） ; there was no statistics difference in short axis radial deformations ; the circumference deformations in septa interventriculare and front septa interventriculare was bigger than that in other ventrieular walls （P 〈 0.05 ）. The average value of the portrait, short axis radial, circumference deformations of CRF patients was lower （ P 〈 0.05 ）. Conclusion STI is preferable for the appraisal of left ventricle function in CRF patients.
