目的：探讨斑点追踪显像（speckle tracking imaging ，STI）在评价维吾尔族（维族）、汉族冠心病患者左心整体收缩功能改变的价值。方法选取确诊的冠心病患者，维吾尔族25例，汉族30例，分析维、汉族患者临床资料、生化指标、冠脉病变、常规心脏超声测值，采用斑点追踪显像技术（STI）测量左心整体纵向应变（GSL）、径向应变（GSR）、圆周应变（GSC），心底部及心尖部旋转运动、扭转角度等。结果维族冠心病患者较汉族年龄偏大；维族患者单支病变较汉族少，多支病变多于汉族；维、汉族患者 GSL、GSR 及 GSC 差异均有统计学意义（P ＜0．05），维族患者心肌应变较汉族减小；维族患者 GSL 的达峰时间长于汉族，差异有统计学意义（P ＜0．05）。维、汉族患者心底部、心尖部旋转角度及扭转角度差异均无统计学意义（P ＞0．05）。结论STI 显示维族冠心病患者心肌收缩功能损害程度较汉族更明显，STI 是一种诊断冠心病患者心肌功能受损程度的准确方法。

Objective To observe the value of speckle tracking imaging (STI)in global left ventricular sys-tolic function in coronary heart disease patients between Uyghur and Han.Methods 25 Uyghur cases and 30 Han cases with coronary heart disease were selected to analyze clinical data,biochemical indicators, coronary artery lesions,routine cardiac ultrasound measurements;to measure global longitudinal strain (GSL),radial strain (GSR),circumferential strain (GSC),rotation and torsion by STI.Results Uyghur CHD patients were older than the Han;Single vessel disease of Uygur coronary lesions less than the Han, but multivessel disease more than the Han;Global longitudinal,radial and circumferential strain were dif-ferent between the two groups (P <0.05);Compared with Han ,Uyghur strain decreases;The peak time of longitudinal strain of Uyghur were longer than Han (P <0.05).Rotation and torsion was not statistical-ly significant between Uyghur and Han (P >0.05).Conclusion Compared with Han,the extent of systol-ic function lesion is more obvious in Uyghur patients with coronary heart disease,the ability of myocardial deformation is reduced ,among longitudinal strain is most obvious.STI provides a sensitive and accurate method for cardiac function of coronary artery disease.
