应用Tei指数对蒙古族妊娠期高血压孕妇胎儿心功能的评价
|
摘要
目的:探讨Tei指数在评价蒙古族妊娠期高血压孕妇胎儿心功能中的价值.方法:选择26名蒙古族妊娠期高血压子痫前期重度孕妇作为观察组,同时选取30名健康孕妇作为对照组,分别测量两组胎儿的等容收缩期时间(isovolumetric contraction time,ICT)、等容舒张期时间(isovolumetric relaxation time,IRT)和左心室射血时间(ejection fraction,ET),并计算Tei指数.结果:观察组胎儿等容收缩期时间(ICT)、等容舒张期时间(IRT)、左心室射血时间(ET)与对照组有显著差异.两组间Tei指数比较,差异有统计学意义.结论:Tei指数可以敏感、准确发现妊娠期高血压孕妇胎儿心肌收缩及舒张功能的异常.
Objective:To investigate the value of Tei index in assessing fetal cardiac function in Mongolian hypertensive pregnant women during pregnancy. Methods:Twenty-six Mongolian women with severe preeclampsia due to hypertension during pregnancy were selected as the observation group;at the same time,thirty healthy pregnant women were selected as the control group. The fetal isovolumetric contraction time(ICT),isovolumetric relaxation time(IRT)and left ventricular ejection time(LVET)of two groups were measured respectively,and the Tei index was calculated. Results:There were significant differences between the observation group and the control group in fetal ICT,IRT and LVET. The Tei index was significantly different between the two groups. Conclusion:Tei index can sensitively and accurately detect fetal myocardial systolic and diastolic dysfunction in hypertensive pregnant women.
