| Sumario: | Thromboembolism in patients with peripheral artery disease (PAD) represents a common cause of morbidity and mortality. In this article, the authors analyse the use of anticoagulants for patients with PAD. Anticoagulants have been used to reduce the risk of venous thromboembolism, but have recently been applied to the arterial circulation. Heparins were introduced to reduce short-term major adverse limb events in patients undergoing arterial revascularisation. Low molecular weight heparins have allowed easier management and carry a lower risk of bleeding than unfractioned heparin. Vitamin K anticoagulants have been tested in trials that included patients with PAD, showing an increased risk of bleeding when compared with aspirin alone, but longer patency rates for venous surgical bypass, although the evidence remains weak. Those anticoagulants are currently recommended only in patients with PAD who need anticoagulation for other diseases. Direct oral anticoagulants have only recently been investigated for use in patients with PAD. Promising results from low dose rivaroxaban plus aspirin have been recently outlined by a randomised controlled trial and supported by international guidelines. |
