Outcome Measures

Primary Outcomes (1)

  • Number diagnosed with pre-eclampsia

    According to the ISSHP, PE is defined as systolic blood pressure at ≥140 mm Hg and/or diastolic blood pressure at ≥90 mm Hg on at least two occasions measured 4 hours apart in previously normotensive women and is accompanied by one or more of the following new onset conditions at or after 20 weeks of gestation: 1. Proteinuria (i.e. ≥30 mg/mol protein:creatinine ratio; ≥300 mg/24 hour; or ≥2 + dipstick); 2. Evidence of other maternal organ dysfunction, including: acute kidney injury (creatinine ≥90 μmol/L; 1 mg/dL); liver involvement (elevated transaminases, e.g. alanine aminotransferase or aspartate aminotransferase \>40 IU/L) with or without right upper quadrant or epigastric abdominal pain; neurological complications ; or hematological complications ; or 3. Uteroplacental dysfunction .

    After 20th week of gestation

Secondary Outcomes (1)

  • Number of women with adverse outcomes

    After 20th week of gestation

Study Arms (2)

Women at high risk for preeclampsia

Using FIGO recommended preeclampsia screening model for the first-trimester which combined maternal risk factors, mean arterial pressure, placental growth factor, uterine artery pulsatility index to evaluate pregnant's risk for preeclampsia. Risk value≥1/100 is defined as screened high risk.

Drug: Low-dose aspirin

Women at low risk for preeclampsia

Using FIGO recommended preeclampsia screening model for the first-trimester which combined maternal risk factors, mean arterial pressure, placental growth factor, uterine artery pulsatility index to evaluate pregnant's risk for preeclampsia. Risk value\<1/100 is defined as screened low risk.

Interventions

FIGO adopts and supports that in high-risk women, defined by the first-trimester combined test, aspirin \~150 mg/night should be commenced at 11-14+6 weeks of gestation until either 36 weeks of gestation, when delivery occurs, or when pre-eclampsia is diagnosed.
