The investigators collected women delivered twice in a row in our hospital. The investigators divided these pregnant women into three groups. Women in the first group did not complicate preeclampsia at both deliveries; Women in the second group complicated preeclampsia at the first delivery or at the second delivery; women in the third group complicated preeclampsia at two deliveries. The investigators explore the risk factors of recurrent preeclampsia and measure blood pressure, blood lipids, thyroid function, glycosylated hemoglobin, ALT, AST, et al. in one year, three years, and five years after the second delivery.
The purpose of this study is to evaluate the risk factors of recurrent preeclampsia and compare the short-term and long-term adverse outcomes of women and their offspring.
