【摘要】：目的应用三维超声斑点追踪显像技术(3D-STI)评价健康孕妇妊娠前后左心室收缩功能的改变。方法选取健康妊娠晚期妇女25例(妊娠组),同期健康未孕妇女25例(对照组)。使用3D-STI测量对照组及妊娠组产前左心室整体纵向收缩期峰值应变(LVGLS)、左心室整体环向收缩期峰值应变(LVGCS)、左心室整体径向收缩期峰值应变(LVGRS)、左心室整体面积收缩期峰值应变(LVGAS)、左心室舒张末期容积(LVEDV)、左心室每搏量(LVSV)及左心室射血分数(LVEF);妊娠组分娩后6周(妊娠后)复查,并作比较。结果与对照组比较,妊娠组产前LVEDV、LVSV、LVEF、LVGLS、LVGCS、LVGRS及LVGAS均增高(P均0.05);妊娠组产前、妊娠后比较,LVEDV、LVSV、LVGLS及LVGAS差异无统计学意义(P均0.05),LVEF、LVGRS及LVGCS差异有统计学意义(P均0.05);妊娠组妊娠后与对照组比较,LVEDV、LVSV、LVGLS及LVGAS差异有统计学意义(P均0.05)。结论 3D-STI为临床评价健康孕妇妊娠前后左心室收缩功能的变化提供了新的方法。
[Abstract]:Objective to evaluate the changes of left ventricular systolic function in healthy pregnant women before and after pregnancy by using 3D-STI. Methods 25 healthy pregnant women (pregnancy group) and 25 healthy non-pregnant women (control group) were selected. Using 3D-STI to measure left ventricular whole longitudinal systolic peak strain (LVGLSN), left ventricular global circumferential systolic peak strain (LVGCSC), left ventricular global radial systolic peak strain (LVGRSs), left ventricular global area contraction (LVGLSN), left ventricular global longitudinal systolic peak strain (LVGLSN), left ventricular global circumferential systolic peak strain (LVGCSC). Phase peak strain (LVGASA), left ventricular end-diastolic volume (LVEDVV), left ventricular volume (LVSVV), left ventricular ejection fraction (LVVEFV), and left ventricular ejection fraction (LVVEFV) were reexamined 6 weeks after delivery (postpregnancy) in pregnancy group. Results compared with the control group, the levels of LVGRS and LVGAS in LVEDVV, LVSVV, LVEF, LVGLSN, LVGCSN, LVGRS and LVGAS in pregnancy group were all increased (P < 0.05). There was no significant difference in LVGLS and LVGAS between LVSVGLs and LVGAS after pregnancy. There were significant differences in LVGRS and LVGCS between LVEDVV and LVSVGRS in pregnancy group compared with that in control group (P < 0.05). Conclusion 3D-STI is a clinical evaluation of healthy pregnancy in pregnancy group. There is a significant difference in LVGLS and LVGAS between pregnant group and control group. Conclusion 3D-STI is a clinical evaluation of healthy pregnancy. The changes of left ventricular systolic function before and after pregnancy provide a new method.
