摘　　要：目的观察妊高征对胎儿心室壁厚度及Tei指数的影响。方法选择妊高征孕妇的胎儿56例,其中妊娠期高血压23例(A组)、轻度子痫前期18例(B组)、重度子痫前期15例(C组)。另选214例正常胎儿为对照组。在四腔心切面,应用M型超声测量各组胎儿舒张末期右室壁、左室壁及室间隔的厚度;测量房室瓣及大动脉瓣口血流频谱的时间间期,计算心室Tei指数。结果与对照组相比,A组胎儿心肌较正常对照组稍增厚,左右心室Tei指数稍增高,但差异无统计学意义;B组胎儿右心室Tei指数增高(P<0.05),其余指标差异无统计学意义;C组胎儿心肌较正常对照组增厚,Tei指数增高(P均<0.05)。结论妊高征可导致胎儿心室壁增厚、Tei指数增高。Objective To observe the influence of pregnancy-induced hypertension syndrome( PIH) on fetal ventricular wall thickness and Tei index. Methods Fifty-six cases of fetuses whose mothers were diagnosed as PIH were selected and divided into three groups,including 23 cases of gestational hypertension( group A),18 cases of mild preeclampsia( group B) and 15 cases of severe preeclampsia( group C); and 214 cases of normal fetuses were selected as the control group. The fetal myocardial thickness of the left and right ventricular wall,ventricular septum was measured in the fourchamber view in relaxation period by M type ultrasound. The time intervals of flow spectrum in atrioventricular valve,aortic and pulmonary valves were measured and then Tei indexes were calculated. Results Compared with the control group,fetal myocardium of group A was slightly thickened,Tei index of right and left ventricle was slightly higher and there was no significant difference( P > 0. 05). Fetal myocardium of group B was slightly thickened,left ventricular Tei index was slightly higher and there was no significant difference in the rest of indexes( P > 0. 05). Fetal myocardium of group C was thicker,and Tei index of right and left ventricle was higher than that of the control group and the difference was statistically significant( all P < 0. 05). Conclusion The fetal ventricular wall was thickened and Tei index was increased in patients with PIH.
