Low-dose aspirin started in the first trimester reduces the risk of preeclampsia in high-risk women. Low molecular weight heparin (LMWH) has shown potential benefits in addition to aspirin for preventing preeclampsia through its anticoagulant, anti-inflammatory, and endothelial protective effects. However, current evidence is limited and conflicting regarding the added value of LMWH to aspirin. This randomized controlled trial aims to evaluate the efficacy of combined aspirin and LMWH, compared to aspirin alone, for reducing the incidence of preeclampsia in high-risk gravidas.",[27,28,29,30,31,32],"Preeclampsia Severe","Toxemia Of Pregnancy","Preeclampsia","Pregnancy Complications","Hypertension, Pregnancy-Induced","Gestational Hypertension",[34,35,36,37,38,39,40,41,42],"preeclampsia","gestational hypertension","toxemia","Preeclampsia prevention","Low molecular weight heparin","tinzaparin","High-risk pregnancy","LMWH","Maternal-fetal medicine","RECRUITING","2026-01-15",{"date":46,"type":47},"2026-01-23","ACTUAL",{"date":49,"type":47},"2023-01-18",{"date":51,"type":21},"2027-07-01",{"name":53,"class":54},"Alexandra Hospital, Athens, Greece","OTHER",""]
