摘　　要：目的探讨三维斑点追踪技术(3D Speckle Tracking Imaging,3D-STI)评价不同孕期妊高症患者心功能改变的临床价值。方法选取2018年1月至2019年12月我院规律产检并分娩的足月单胎孕妇,符合纳入研究病例共374例。其中正常孕妇共187例,妊娠期高血压疾病孕妇187例,采集两组的左室常规二维超声数据,并以3D-STI对所获取的图像进行分析,测量左室整体纵向应变(Global Longitudinal Peak Strain,GLS)、整体径向峰值应变(Global Radial Peak Strain,GRS)、整体周向峰值应变(Global Circumferential Peak Strain,GCS)。结果观察组的心率、左心室舒张末内径、左室舒张末容量、心输出量水平显著高于对照组,室间隔与左室壁厚度显著高于对照组(P<0.05);左室收缩末容量及射血分数与对照组比较,差异无统计学意义(P>0.05);本研究中试验组患者左室三维GLS、GCS、GRS绝对值均显著减低(P<0.05)。结论尽早在妊娠高血压患者中行3D-STI可以更早期评估其心功能变化,有利于进一步的诊疗。Objective To investigate the clinical value of 3D speckle tracking imaging in evaluation of changes of cardiac function in pregnancy-induced hypertension patients in pregnancy.Methods A total of 374 full-term single pregnant women selected from the hospital from Jan in 2018 to December in 2019,and a questionnaire survey was conducted,including 187 cases in normal pregnancy group,187 cases in Hypertensive disorders complicating pregnancy group.Two groups of left ventricular conventional data were collected,and the imaging were analyzed by 3D-STI.The global longitudinal peak strain(GLS),global radial peak strain(GRS),global circumferential peak strain(GCS)were measured.Results Compared with controls,GLS,GRS and GCS reduced markedly in pre-HT group(all P<0.05).Compared with control group,HR,LVIDd,IVSd,LVPWd,EDV,CO increased markedly in pre-HT group(P<0.05).There were no significant difference of ESV、LVEF(%)between pre-HT group and controls(P>0.05).Conclusion The early application of 3D-STI in PIH patients can effectively observe left ventricular torsion and rotation motion,facilitate early evaluation of cardiac function of pregnancy-induced hypertension patients.
