Clinical Risk Factors and Timing of Recurrent Venous Thromboembolism During the Initial 3 Months of Anticoagulant Therapy

Abstract

During the initial 3 months of anticoagulant therapy, recurrent VTE is more likely to occur in patients with cancer, chronic cardiovascular disease, chronic respiratory disease, or other clinically significant medical disease. Patients with PE are as likely to develop recurrent VTE as those with DVT; however, recurrence is more likely to be fatal in patients who initially present with PE.
