Key result
Extended anticoagulation for secondary VTE requires risk factor guidance and indefinite treatment for unprovoked cases.
Why the study?
VTE occurring after exposure to minor risk factors poses clinical challenges in estimating recurrence risk and guiding extended anticoagulation decisions.
Does the classification of VTE risk factors (provoked vs unprovoked) guide the optimal duration of anticoagulant treatment to prevent recurrence?
Does the classification of VTE risk factors (provoked vs unprovoked) guide the optimal duration of anticoagulant treatment to prevent recurrence?
Tailoring the duration of anticoagulation for VTE based on the presence and persistence of provoking risk factors is crucial for balancing the risk of recurrence against bleeding.

Becattini et al. (2023) conducted a review in Venous thromboembolism (VTE). Anticoagulant treatment was evaluated. Extended anticoagulation beyond 3 months for secondary VTE prevention should be guided by the presence and persistence of major or minor risk factors, with indefinite treatment for unprovoked VTE.
