摘要
目的探讨Tei指数评价妊娠晚期妊高征胎儿心室功能的价值,并比较妊高征胎儿左、右心室受损程度有无差异。方法应用多普勒超声心动图测量30名孕龄在28～40周的妊高征胎儿及55名孕龄在28～40周正常对照胎儿左、右心室多普勒时间间期,获得左、右心室Tei指数,比较妊高征组与正常对照组Tei指数有无差异。比较妊高征组左、右心室Tei指数有无差异。结果妊高征组左、右心室Tei指数均较正常对照组显著增高(P<0.01);妊高征组左、右心室Tei指数比较无差异性(P>0.05)。结论 Tei指数能简便、敏感地评估胎儿心室整体收缩、舒张功能,妊高征胎儿左右心室功能损害程度无明显差异。
Objective To investigate the value of Tei index and the sensitivity of left versus right ventricular Tei index in evaluating the fetal cardiac function in pregnancy-induced hypertension syndrome in the third trimester. Methods Fetal echocardiograms were performed in 30 women with pregnancy-induced hypertension （PIH） syndrome and 55 with normal pregnancy of the third trimester. Tei index was obtained by calculating the ratio of the isovolumic time （isovolumic contraction and relaxation time） to the ejection time of the left and right ventricle. Comparisons of the Tei index were made between the PIH group and control group, and also between the left and right ventricles in each group. Results Significant difference was found in the left and right ventricular Tei index between PIH group and control group. No difference was noted between the left and right ventricular Tei index in the PIH group. Conclusions Tei index is a useful indicator in evaluating fetal global cardiac function, for which purpose the left ventricular Tei index can be as sensitive as the right ventricular Tei index.
