What is the preferable antithrombotic intervention for stroke patients?
Anticoagulation with VKA is preferable over aspirin to reduce recurrent arterial thromboses. An INR with a target range of 2 to 3 is preferable over an INR with a range >3 because higher-intensity anticoagulation is not superior in preventing thrombotic events and is associated with a higher risk of hemorrhagic complications.
