Study Details

Study Description

Brief Summary

Prophylaxis with low-dose aspirin has been recommended to prevent preeclampsia, the rationale being that hypertension and abnormalities of coagulation in this disease are caused in part by an imbalance between vasodilating and vasoconstricting prostaglandins. Low-dose aspirin therapy inhibits thromboxane production more than prostacyclin production and therefore should protect against vasoconstriction and pathologic blood coagulation in the placenta. Initially, several single-center trials, mostly among women at increased risk for preeclampsia, demonstrated a substantial reduction in the risk of proteinuric hypertension as well as reductions in the incidences of preterm birth, infants small for gestational age, and perinatal death,

Detailed Description

This will be a randomized control trial to estimate the efficacy of two doses (80 mg versus 160 mg) of aspirin for prevention of preeclampsia in High-Risk Pregnant Women identified in the first trimester to be at high risk.

  • Outcome Measures

    Primary Outcome Measures

    1. Number of Participants With early Preeclampsia [6 months]

      The number of cases of preeclampsia that appear in both groups before 34 weeks of pregnancy.Blood pressure greater than 140/90 on 2 occasions 6 hrs apart and significant proteinuria (greater than 300 mg in 24 hrs) before 34 weeks gestation

    Secondary Outcome Measures

    1. Prevention of preeclampsia between 37 and 41 [6 months]

      The number of cases of preeclampsia that appear in both groups between 37 and 41 weeks of pregnancy.

    2. The number of cases of Fetal Growth Restriction [6 months]

      The number of cases of fetal growth restriction, defined as a fetal weight below the 10th percentile and an abnormal umbilical cord doppler that appear in both groups at any given time during pregnancy.

    3. The number of cases of preterm birth [6 months]

      The number of cases delivered before 37 weeks gestation
