Abstract

It is currently unknown whether thrombin generation is associated with venous thromboembolism (VTE) recurrence, major bleeding, and mortality in the elderly. Therefore, our aim was to prospectively study the association between thrombin generation and VTE recurrence, major bleeding and mortality in elderly patients with acute VTE. Consecutive patients aged ≥65years with acute VTE were followed for 2 years starting from 1 year after the index VTE. Primary outcomes were VTE recurrence, major bleeding and mortality. Thrombin generation was assessed in 565 patients 1 year after the index VTE. At this time, 59% of patients were still anticoagulated. Thrombin generation was discriminatory for VTE recurrence, but not for major bleeding and mortality in non-anticoagulated patients. Moreover, peak ratio (adjusted subhazard ratio 4.09, 95% CI, 1.12-14.92) and normalized peak ratio (adjusted subhazard ratio 2.18, 95% CI, 1.28-3.73) in presence/absence of thrombomodulin were associated with VTE recurrence, but not with major bleeding and mortality after adjustment for potential confounding factors. In elderly patients, thrombin generation was associated with VTE recurrence, but not with major bleeding and/or mortality. Therefore, our study suggests the potential usefulness of thrombin generation measurement after anticoagulation completion for VTE to help identifying among elderly patients those at higher risk of VTE recurrence.
