Abstract

Objectives: To investigate factors that effect fetal cardiac function in pre-eclampsia pregnant women. Objects and methods: Fortypregnant women,who have some characteristics:greater than or equal to 18 year olds, have 28th week of pregnancy and above, not suffer from acute and chronic diseases, basic prenatal screening tests are nomal, come for medical examination and treatment at Department of Obstetrics and Gynecology and Vietnam National Heart Institute of Bach Mai Hospital from August 2019 to August 2020. Results and Conclusions: There are some clinical factors affect the fuction of the fetal right heart expressed by Tei index of the right ventricular: pre-pregnant BMI (r=0,336, p<0,05), systolic blood pressure (r=0.333, p<0.05) and diastolic blood pressure (r = 0.381, p <0.05). In addition, systolic blood pressure (r = 0.364, p <0.05), diastolic blood pressure (p = 0.337, p <0.05) and LDL-C (r = 0.471, p <0.05) are factors that affect the fetal left cardiac function through the left ventricular Tei index. For Doppler untrasound of uterine artery, there are positivecorelation between Resistive Index (RI) and some indicators, such as: cardiothoracic ratio (r=0,726, p<0,001),systole right ventricular diameter (r=0,730, p<0,05), cardiac morphology index (relatively close correlation, p<0,05) and Tei index of the left ventricular (r=0,374, p<0,05). The thickness of the fetal cardiac wall and fetal cardiac VTI index measured through the aorta and pulmonary artery in the group with resistive index of uterine arterial RI> 0.55 are significantly greater than the group with RI ≤0.55 with p <0.05.
