Abstract
The research was aimed at analyzing the value of the optimized eXtreme Gradient Boosting (XGBoost) algorithm-based ultrasound cardiogram images in the diagnosis of pregnant hypertension patients. A total of 145 pregnant women (85 cases suffered from hypertension disease during pregnancy and 60 other normal women were healthy) were selected as the reference to the comparison and analysis of ultrasound cardiac function parameter, common carotid artery parameter, and the coupling relationship between hearts and cervical vessels of pregnant hypertension patients. The results demonstrated ultrasound cardiac function parameter of pregnant hypertension patients as follows. The maximum volume of the left atrium (LAVmax) was 35.65 mm, left ventricular end-systolic volume (LVESV) was 31.07 mm, and left ventricular end-diastolic volume (LVEDV) was 88.73 mm. All the above indexes were obviously higher than those of the normal control group (P < 0.05). Besides, intima-media thickness (IMT) of common carotid artery (465.84 μm), pulse wave velocity (PWV) (8.09 m/s), pressure of turning point 1 from isovolumic contraction phase to ejection phase (PT1) (126.5 mmHg), arterial enhancement pressure (AP) (6.14 mmHg), and arterial pressure enhancement index (8.58%) were all significantly higher than those of the normal control group (P < 0.05). In addition, the correlation between the coupling (E/A) of hearts and carotid artery of pregnant hypertension patients and PWV was not obvious (r = −0.08432, P > 0.05). The results of the research indicated that intima-media inside carotid artery of pregnant hypertension patients thickened obviously, and it became less elastic compared with that of normal healthy pregnant women. What is more, cardiac morphological changes were manifested mainly as the enlargement of the left atrial chamber and the thickening of the interventricular septum. Volume load and blood flow velocity both increased, and left ventricular diastolic function was damaged. XGBoost algorithm-based ultrasound cardiogram images could improve the diagnostic effects of hypertension during pregnancy effectively.

Clinical ultrasonic cardiogram was applied in auxiliary diagnosis of high blood pressure during pregnancy, and the research of the application value of auxiliary diagnosis of high blood pressure during pregnancy by the imagological features of ultrasonic cardiogram, which was based on XGBoost algorithm, was the hot issue on the research about imagology [13]
Summary
In this period, every system throughout pregnant women’s body underwent a series of changes to promote fetuses’ growth and development. Hypertensive disorder complicating pregnancy (HDCP) is a kind of common and severe complication appearing only during pregnancy. The current incidence of this disease accounted for 5%-10% among all pregnant women, which was a major cause of death of pregnant women [2]. It was shown that HDCP was caused by multiple factors affecting each other, and this symptom would potentially result from many other factors, such as pregnant women’s age, the number of pregnancies, familial inheritance history, nutritious condition, social and economic status, physical activities they engage in, and neuroendocrine [3, 4].
