About this study

This is an observational study designed to evaluate the effectiveness and safety of direct oral anticoagulants (DOACs) compared with vitamin K antagonists (VKAs) for the secondary prevention of thrombosis in patients with low-risk thrombotic antiphospholipid syndrome. Antiphospholipid syndrome is an autoimmune disorder associated with an increased risk of thrombotic events. Although VKAs have traditionally been the standard treatment, DOACs are increasingly used in clinical practice in selected patients, despite limited evidence in this setting. This study includes patients with previous venous thrombosis and a low-risk serological profile who are treated with either DOACs or VKAs according to routine clinical practice. The primary objective is to compare thrombotic recurrence and bleeding events between both treatment strategies. The results of this study will contribute to improving knowledge about the use of DOACs in patients with low-risk thrombotic antiphospholipid syndrome.
