Prediction of bleeding events using the VTE-BLEED risk score in patients with venous thromboembolism receiving anticoagulant therapy (Review)

Venous thromboembolism (VTE) is a major healthcare problem due to its high incidence, significant mortality rate from pulmonary embolism, high recurrence rate and morbidity from long-term complications. After a first episode of VTE all patients must receive anticoagulant treatment for 3 months. Further anticoagulation is recommended in patients without transient risk factors for VTE or patients with active cancer, if they are not at a high risk for bleeding. The VTE-BLEED risk score was created with the purpose of enabling a better stratification of the bleeding risk during stable anticoagulation after a first VTE. Currently, it is the most validated risk score in VTE settings (selected and non-selected cohorts). It has a good prediction power for major bleeding events in patients receiving any of the currently available classes of oral anticoagulants, and it can identify patients at risk of intracranial and fatal bleeding events. The aim of our review was to highlight the strengths of the VTE-BLEED risk score, to acknowledge its weak points and to properly position its use in current medical practice.
