Should we consider giving anticoagulation to patients with increased thrombotic risk who have Covid-19?

Advice from a Consultant in Infectious Diseases

Q.      Should we consider short courses of heparin in patients with increased thrombosis risk (eg previous DVT) if they become unwell with Covid-19?


  • We do not have the results of a randomised controlled trial to inform this in primary care
  • We know that patients with Covid-19 are at increased risk of large and small vessel thrombosis
  • But we do not yet know whether the group that do not require hospital admission would benefit from a short course of LMWH
  • I would suggest that if there is clinical concern to refer in for assessment. If their D-dimer is raised there may well be a case for further imaging depending on the clinical scenario
