Clinical Analysis of Echocardiography and Serum IL-6 and TNF- α Changes in Pregnant Women with Hypertension

Abstract

In order to explore the changes and clinical significance of serum TNF-α and IL-6 and ET levels in the pathogenesis of hypertensive disorders of pregnancy (HDIP), echocardiography, and serum IL-6 and TNF-α changes in pregnant women with a hypertensive disorder, a clinical analysis method was proposed. A retrospective analysis of 59 pregnant women who visited the obstetrics department of a provincial hospital was divided into 2 groups. The normal control group consisted of 32 normal, uncomplicated pregnant women; the preeclampsia group included 27 patients with systolic blood pressure > 140 mmHg and/or diastolic blood pressure > 90 mmHg who developed proteinuria after 20 weeks of gestation. The levels of TNF-α and IL-6 in serum of normal pregnant women and pregnant women with preeclampsia were detected by enzyme-linked immunosorbent assay (ELISA). The results showed that compared with normal pregnant women, the serum levels of TNF-α and IL-6 in the early pregnant women of Zizhi were significantly increased, and the trend of increased TNF-α and IL-6 levels was related to the severity of complications. With the mean pulmonary arterypressure > 50 mmHg, the serum TNF-α level of pregnant women was significantly higher than that of pregnant women with mean pulmonary arterypressure < 50 mmHg. The analysis found that the serum levels of TNF-α and IL-6 in patients with hypoxic gestational hypertension were significantly increased, and the results of lung tissue immunohistochemistry also showed that serum TNF-α and IL-6 levels in patients with hypoxic gestational hypertension were significantly increased. And serum TNF-α and IL-6 levels were positively correlated with right ventricular systolic blood pressure (RVSP). Conclusion. This study revealed that the elevated levels of serum TNF-α and IL-6 are closely related to the pathophysiological process of gestational hypertension. Serum levels of TNF-α and IL-6 and ET were significantly increased, and the changes of serum TNF-α and IL-6 and ET levels had important clinical value for closely monitoring the severity of the disease and the development of the disease.
