Abstract To investigate the influence of the uterine arterial hemodynamic parameters of pregnant women with gestational hypertension on their fetal development indexes of heart function. Methods:112 pregnant women with gestational hypertension were selected in research group，and 112 normal pregnancy were selected in control group from February 2017 to December 2020. The values of uterine arterial pulsatility index (PI) and resistance index (RI) of the women, and the values of fetal umbilical artery PI and RI, and the value of fetal myocardial composite index (Tei) were compared between the two groups. The correlation between the uterine arterial hemodynamic parameters of the women in the research group and their fetal Tei index was analyzed. Results：The values of uterine arterial PI (1.42±0.14), RI (0.55±0.13), and S/D (2.65±0.26) of the women, and the fetal umbilical artery PI (0.78±0.21), RI (0.48±0.21), and S/D (2.52±0.17) in the research group were all significantly higher than those in control group. The values of PI, RI, S/D of uterine artery and fetal umbilical artery of the women with gestational hypertension, the women with mild preeclampsia, and the women with severe preeclampsia had increased gradually (all P<0.05). The value of fetal left ventricular Tei (0.45±0.14) and right ventricular Tei (0.46±0.12) of the women in the research group were significantly higher than those of the women in the control group. The values of left and right ventricular Tei of the women with gestational hypertension, the women with mild preeclampsia, and the women with severe preeclampsia had increased gradually (all P<0.05). Correlation analysis showed that the values of PI, RI, S/D of uterine artery of the women and the fetal umbilical artery were positively correlated with the values of left and right ventricular Tei (all P<0.05). Conclusion：The hemodynamic parameters of uterine arterial of pregnant women with gestational hypertension are abnormal，which can lead to the adverse effect on their fetal heart development function.
