Official title

Low-molecular-weight Heparin to Prevent Recurrent VTE in Pregnancy: a Randomized Controlled Trial of Two Doses

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This is a randomized-controlled open-label trial comparing two different doses of low-molecular-weight heparin (LMWH) in pregnant patients with a history of previous venous thromboembolism (VTE). Both doses are recommended doses in the 2012 guidelines of the American College of Chest Physicians (ACCP), but it is not known which dose is more efficacious in preventing recurrent venous thromboembolism in pregnancy. Patients enter the study and will be randomized as soon as a home test confirms pregnancy. LMWH will be administered until 6 weeks postpartum. Follow-up will continue until 3 months postpartum. Patients will be recruited by their treating physician, either an obstetrician or internist.
