About this study

Venous thromboembolism (VTE) including deep vein thrombosis (DVT) and pulmonary embolism (PE) is a frequent disease and the third most common cause of cardiovascular death in the world after myocardial infarction and stroke. Anticoagulant therapy drastically reduces the risk of early VTE recurrence and death, but it exposes patients to a substantial risk of bleeding. Hence, determining the optimal duration of anticoagulant treatment for VTE is a major public health issue. When major transient risk factors for VTE are identified (major surgery, immobilization...), patients generally do not need to extend anticoagulation beyond 3 months, whereas for VTE diagnosed in the context of cancer, therapeutic anticoagulation is required for as long as the cancer is considered "active". However, in more than 50% of cases, venous thromboembolic disease occurs spontaneously, i.e. without any significant clinically detectable circumstance (known as unprovoked venous thromboembolic disease). In such patients, the risk of recurrence is high (35% recurrence rate at 5 years, with a 10% risk of death per recurrence). Scientific societies therefore recommend continuing anticoagulant treatment "indefinitely" (i.e. without programming a stop date or long-term treatment). However, this practice exposes these patients to an ongoing, non-negligible increase in the risk of bleeding, which could ultimately exceed the risk of recurrence of venous thrombo-embolic disease. Optimizing anticoagulant thera…
