Low-dose heparin therapy in the long-term management of venous thromboembolism.

The efficacy of a six-month course of low-dose heparin therapy was compared to a conventional warfarin regimen by a prospective, controlled trial in 48 patients with pulmonary embolism or deep venous thrombosis of the legs. All subjects had complicated medical illnesses and a high risk of recurrent thromboembolism. Bleeding complications were virtually negligible during heparin therapy and occurred significantly more frequently in patients receiving warfarin. Heparin was as effective as warfarin in the prevention of recurrent thromboembolism. Patient compliance with the two treatment regimens was comparable. Self-administered, low-dose heparin therapy is a useful alternative to warfarin in the long-term management of complicated thromboembolic disorders.
