Predictors and Outcomes of Recurrent Venous Thromboembolism in Elderly Patients

Elderly patients with acute venous thromboembolism have a substantial long-term risk of recurrent venous thromboembolism, and recurrence carries a high case-fatality rate. Only 2 factors, unprovoked venous thromboembolism and proximal deep vein thrombosis, were independently associated with recurrent venous thromboembolism, indicating that traditional risk factors for venous thromboembolism recurrence (eg, cancer) may be less relevant in the elderly.
