摘　　要：目的应用超声斑点二维追踪成像技术(STI)检测妊高征患者左心室收缩功能,探讨STI评价左心室收缩功能的价值。方法采集妊高征患者34例、正常对照组31例的心尖四腔清晰二维图像,获取收缩期左心室纵向应变峰值。结果妊高征组左心室节段收缩期纵向峰值应变均明显低于对照组(P<0.01)。结论超声二维斑点追踪成像技术能够评价妊高征患者左心室局部和整体收缩功能异常。Objective To evaluate left ventricular longitudinal strain in Pregnancy-induced Hypertension （ PIH ） women by two dimensional ultrasound speckle-tracking imaging （ STI ）. Methods Two-dimensional active images of left ventricular at four-chamber view were acquired in 34 patients with PIH and in 31 healthy pregnancy women to obtain the peak systolic longitudinal strain of left ventricle. Results The peak systolic longitudinal strain of different segments in PIH group decreased compared with the control group（ P 〈 0.01 ）. Conclusion STI can exactly evaluate the Impairment of regional and global left ventricular systolic function in PIH.
