Pregnancy-induced hypertension, especially preeclampsia (PE), is one of the leading causes of increased maternal and perinatal morbidity and mortality worldwide. And the circulating cell free fetal nucleic acid (cff-DNA) analysis of pregnant women can be used as an early prediction of the occurrence and development of PE. By summarizing and analyzing the correlation between cff-DNA and PE and its possible mechanism, this paper further explained that the occurrence of PE may be related to DNA methylation, and discussed its limitations as a biomarker, so as to provide reference for the effective prediction of preeclampsia.
