目的利用心肌做功指数(Tei指数)监测孕晚期妊娠期高血压疾病(HDCP)对胎儿心脏功能的影响。方法孕晚期发现患有妊娠期高血压疾病的产妇40例(HDCP组),同时选取正常胎儿40例(正常胎儿组),在28~32周、33~37周、37周以上3个孕周时段多次测量胎儿左、右心室Tei指数,进行统计学分析。结果 HDCP组胎儿左、右心室Tei指数与正常胎儿组比较,差异有统计学意义(P<0.05)。结论 Tei指数在孕晚期妊娠期高血压疾病对胎儿心脏功能影响的检测中有较大价值。
Objective To monitor the effect of HDCP during pregnancy in third trimester on fetal cardiac function by using myocardial work index (Tei index). Methods Forty pregnant women (HDCP group) with gestational hypertension were enrolled in the third trimester of pregnancy and 40 normal fetuses (normal fetus group) were enrolled in this study. The gestational age ranged from 28 to 32 weeks, from 33 to 37 weeks and from 37 weeks to 3 gestational weeks Multiple fetal left and right ventricular Tei index was measured for statistical analysis. Results HDCP group fetal left and right ventricular Tei index compared with the normal fetus group, the difference was statistically significant (P <0.05). Conclusion The Tei index is of great value in the detection of fetal cardiac function in the third trimester of pregnancy.
