目的:应用三维斑点追踪技术(3D STE)评价子痫前期患者妊娠晚期左心结构与功能,并追踪其产后变化。方法:2016年8月至2017年10月75例在苏州市立医院本部就诊的育龄期妇女,其中: PE(子痫前期)组50例,NP(正常妊娠)组25例,分别在妊娠晚期及产后12-18周内利用三维斑点追踪成像技术采集心尖四腔全容积图像,分析左室重构及心肌纵向应变、圆周应变、径向应变、面积应变。结果:子痫前期妊娠晚期左室整体心肌GLS、GRS、GCS、GAS均下降,产后12-18周GLS较正常组仍有统计学差异。结论:子痫前期患者妊娠晚期心脏离心性重构,心肌受损,产后随着血压下降,心脏重构、心功能较产前改善,但心肌损害仍存在,而三维斑点追踪技术为临床评价子痫前期心功能变化提供新方法。 |

Abstract: |
Objective: To investigate the left ventricular structure and function in preeclampsia during the third trimester of pregnancy by three-dimensional speckle tracking imaging and to observe its changes in postpartum period. Methods: Totally 75 women of childbearing age from August 2016 to October 2017 in Suzhou Municipal Hospital were chosen. PE group includes 50 preeclampsia women, NP group includes 25 healthy pregnant women. To collect the 3D full volume datasets on the apical four chamber full volume images in the third trimester of pregnancy and 12-18 weeks after delivery,then analyzed the left ventricular remodeling and the global longitudinal strain(GLS), global circumferential strain(GCS), global radial strain(GRS) and global area strain(GAS)of 17 segments .Results:Compared with NP group,the patients in PE group showed that GLS, GRS, GCS and GAS decreased in the third trimester of pregnancy,and GLS was still below at 12-18 weeks after delivery. Conclusion: patients with preeclampsia, cardiac remodeling in the third trimester of pregnancy and myocardial strain decreased significantly. With the decrease of blood pressure, cardiac remodeling and cardiac function improved after postpartum,but myocardial damage still exists.3D-STI is a new way for evaluation of left ventricular function changes in preeclampsia. |
