ABSTRACT

Objective:

To analyze the correlation between phonographic cardiac function and uterine artery resistance index (RI) in pregnant women with hypertension of different conditions during pregnancy by color Doppler ultrasonically.

Methods:

A total of 100 pregnant women with gestational hypertension admitted to Lishui People′s Hospital from January 2020 to February 2021 were selected and divided into gestational hypertension group (40 cases), mild pre-eclampsia group (30 cases) and severe pre-eclampsia group (30 cases) according to the severity of their disease. Another 30 normal pregnant women who underwent physical examination during the same period were selected as the control group. The left ventricular function parameters isovolumetric relaxation time (IVRT), left ventricular ejection fraction (LVEF), left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume(LVESV), left atrial volume index (LAVI) and uterine arter RI in 4 groups were quantitatively analyzed by ultrasound during 28 to 38 weeks of gestation. The correlation between cardiac ultrasound parameters and of pregnant women RI were analyzed.

Results:

As the severity of the disease, the levels of IVRT, LVEDV, LVESV, LAVI were gradually rised, and the level of LVEF was gradually decreased, there were significant differences among the 4 groups ( P<0.05). The uterine arter RI in the control group, gestational hypertension group, mild pre-eclampsia group and severe pre-eclampsia group was 0.42 ± 0.04, 0.50 ± 0.05, 0.54 ± 0.11, 0.58 ± 0.06, there was significant difference ( F = 34.11, P<0.001), and as the severity of the disease , the level of uterine arter RI was gradually rised, there were significant differences among the 4 groups ( P<0.05). Pearson correlation analysis showed that IVRT had certain correlation with RI in the 4 groups ( r = 0.331, 0.450, 0.531, 0.582; P<0.05). In mild and severe pre-eclampsia group, there were a certain correlation between LVEDV, LVESV and RI (in mild pre-eclampsia group r = 0.360 and 0.411, P<0.05; in severe pre-eclampsia group r = 0.383 and 0.451, P<0.05).

Conclusions:

The left heart function of pregnant women with different conditions evaluated by ultrasound showed a downward trend, and the uterine artery RI increased gradually in pregnant women with severe pre-eclampsia, and RI was closely related to the cardiac ultrasound parameter IVRT.
