Brief Summary:
Preeclampsia is one of the most serious complications in pregnancy that causes maternal death and preterm delivery, the incidence rate is about 5~10% in Chinese population. Series studies has show that multiple markers in early pregnancy has the potential to predict preeclampsia effectively but has show crowd difference. Since preeclampsia is a placental-derived disease, early prevention with aspirin and other intervention has the potential to "treat" the disease .Preeclampsia prediction will change the way doctors treat the disease and profoundly improve both the outcome of mother and the baby.

Condition or disease

Detailed Description:
The prospective multi-center observational study aimed to recruit at least 12,000 pregnant woman during the first trimester conducted among 21 medical centers in China. The medical history of each candidate was recorded , blood pressure was measured , blood sample was taken between 11 gestational weeks and 13+6 gestational weeks, to get the PlGF and PAPPA tested. Routine ultrasound was taken with measurement of the uterine artery pulsatility index. The results of the recruited patients were not released to the patients or the doctor. Pregnancy outcome was recorded as to whether the women develop preeclampsia , the SGA babies, or low birth Apgar score and other preeclampsia related adverse maternal and neonatal outcomes. The basic medical information, the mean artery pressure, the PlGF and PAPPA MOM, the UtA PI were used in combination to do the risk stratification, and to develop prediction model for Chinese people.

Primary Outcome Measures :
  1. preeclampsia , early-onset preeclampsia and late-onset preeclampsia [ Time Frame: July,2018 to July,2019 ]
    Primary outcome was whether women in the study population develop preeclampsia, and whether the preeclampsia was diagnosed before or after 34 weeks of gestation: 1.preeclampsia was defined as denovo hypertension at or after 20 weeks' gestation accompanied by proteinuria or evidence of end‐organ dysfunction.2. early-onset preeclampsia was preeclampsia diagnosed before 34 gestational weeks.

Secondary Outcome Measures :
  1. Gestational age at delivery [ Time Frame: July,2018 to October,2019 ]
    preterm delivery will be defined as gestational age before 37 completed weeks, severe preterm delivery will be defined as gestational age before 32 completed weeks

  2. Fetal preeclampsia-related adverse outcomes [ Time Frame: July,2018 to October,2019 ]
    Fetal preeclampsia-related adverse outcomes are defined as perinatal/fetal death, iatrogenic delivery earlier than 34 weeks, intrauterine growth restriction (IUGR), placental abruption, respiratory distress, necrotizing enterocolitis or intraventricular hemorrhage.

  3. Maternal preeclampsia-related adverse outcomes [ Time Frame: July,2018 to October,2019 ]
    Maternal preeclampsia-related adverse outcomes are defined as maternal death, pulmonary edema, acute renal failure, cerebral hemorrhage, and cerebral thrombosis or disseminated intravascular coagulation.
