目的:研究妊娠期高血压疾病(HDCP)患者于晚期妊娠期不同胎龄胎儿心脏Tei指数的变化。方法:应用超声心动图测量41例HDCP患者的胎儿(28～32周,32+1～36周)和41例与其胎龄匹配的正常胎儿的心脏多普勒时间间期,计算左、右心室Tei指数范围,分析不同胎龄胎儿心室Tei指数间有无统计学差异。结果:晚期妊娠中胎儿胎龄不同,其心脏Tei指数改变亦不同,病例组与对照组胎龄为28～32周的胎儿左、右心室Tei指数比较,右心室Tei指数病例组高于对照组,差异具有统计学意义(P<0.05),病例组与对照组胎龄为32+1～36周的胎儿左、右心室Tei指数比较,病例组胎儿左、右心室Tei指数均高于对照组,差异具有统计学意义(P<0.05)。结论:妊娠期高血压疾病(HDCP)患者于晚期妊娠期胎儿心脏Tei指数改变与HDCP患者胎儿胎龄有关。
Objective: To study the change of Tei index in gestational hypertension (HDCP) patients with fetal heart in different gestational age. Methods: Echocardiography was used to measure the time interval of cardiac Doppler in fetus (28-32 weeks, 32 + 1-36 weeks) in 41 patients with HDCP and 41 normal fetuses with gestational age. Left ventricular Tei index range, analysis of different gestational age fetal ventricular Tei index was statistically significant. Results: In the third trimester of pregnancy, the fetal Tei index varied with different fetal gestational age. The Tei index of the right and left ventricles of the fetus in the case group and the control group was significantly higher than that of the control group , The difference was statistically significant (P <0.05). The Tei index of left and right ventricles of fetal fetus at gestational age of 32 + 1-36 weeks in case group and control group was higher than that in control group , The difference was statistically significant (P <0.05). CONCLUSION: Changes in fetal cardiac Tei index in patients with HDCP during late pregnancy are associated with fetal gestational age in patients with HDCP.
