摘　　要：目的探讨三维斑点追踪成像(3-dimensional speckle tracking imaging,3D-STI)技术评价妊娠高血压综合征(pregnancy-induced hypertension syndrome,PIHS)患者产前和产后左心室收缩功能的临床价值。方法采用3D-STI测量32例待产的PIHS孕妇(PIHS产前组)、30例产后3个月复查的PIHS产妇(PIHS产后组)及40例待产的正常孕妇(正常对照组)的左心室整体纵向收缩期峰值应变(left ventricle global longitudinal strain,LVGLS)、左心室整体径向收缩期峰值应变(left ventricle global radial strain,LVGRS)、左心室整体圆周收缩期峰值应变(left ventricle global circumferential strain,LVGCS)、左心室整体面积收缩期峰值应变(left ventricular global area peak systolic strain,LVGAS)值,并进行比较。结果与正常对照组比较,PIHS产前组LVGLS值降低(P<0.05),LVGRS、LVGCS、LVGAS值无明显变化(P>0.05);PIHS产后组LVGLS、LVGRS、LVGCS、LVGAS值无明显变化(P>0.05)。与PIHS产前组比较,PIHS产后组LVGLS值升高(P<0.05),LVGRS、LVGCS、LVGAS值无明显变化(P>0.05)。结论 3D-STI技术通过评估PIH患者产前及产后3个月左心室的三维整体应变,可反映PIH患者分娩前后左心室整体收缩功能的改变,为临床早期判断及治疗提供参考。ABSTRACT：Objective To investigate the clinical value of three-dimensional speckle tracking im-aging（3D-STI）in assessment of prenatal and postnatal left ventricular systolic function in pa-tients with pregnancy-induced hypertension（PIHS）.Methods The left ventricular global peak longitudinal strain（LVGLS）,left ventricular global peak radial strain（LVGRS）,left ventricular global peak circumferential strain（LVGCS）and left ventricular global peak area strain（LVGAS） were measured by 3D-STI in 32 antepartum PIHS patients（antepartum PIHS group）,30 3-month postpartum PIHS patients（postpartum PIHS group）,and 40 healthy pregnant women（normal control group）.Results Compared with normal control group,the LVGLS decreased in antepar-tum PIHS group（P 〈0.05）.However,no differences were found in LVGRS,LVGCS and LVGAS between normal control group and antepartum PIHS group,as well as in LVGLS,LVGRS, LVGCS and LVGAS between normal control group and postpartum PIHS group（P 〉0.05）.Com-pared with antepartum PIHS group,the LVGLS increased in postpartum PIHS group（P 〈0.05）. There were no differences in LVGRS,LVGCS and LVGAS between antepartum PIHS group and postpartum PIHS group（P 〉0.05）.Conclusion The 3D-STI technique can sensitively reflect the changes in prenatal and postnatal left ventricular systolic function in PIHS patients through as-sessing the global response of left ventricle.Therefore,3D-STI technique provides a reference for early diagnosis and treatment of PIHS.
