Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The incidence of gestational hypertension and preeclampsia in the assisted reproductive technology population during pregnancy was significantly higher than that in the general normal pregnancy population. The use of assisted reproductive technology in this population due to infertility is often accompanied by many hypertension-related factors. We established a prospective cohort study based on assisted reproductive technology pregnancy population and natural pregnancy population. Through continuous monitoring of blood pressure changes and other risk factors during pregnancy in the two groups, we explored the trajectory trend and inflection point of assisted reproductive technology pregnancy population blood pressure during pregnancy. Through factor analysis, the risk factors of elevated blood pressure during pregnancy can be clearly identified, so as to carry out early intervention and strengthen the control of risk factors of elevated blood pressure in assisted reproductive technology population, in order to expect benign maternal and infant outcomes.
