What are the benefits and risks of different stroke prevention strategies for patients with nonvalvular AF?
The benefits and risks of different stroke prevention strategies for patients with nonvalvular AF vary depending on the type of treatment. Anticoagulants such as warfarin and non-vitamin K antagonist oral anticoagulants (NOACs) are the most commonly used stroke prevention strategies for nonvalvular AF. These medications reduce the risk of ischemic stroke by inhibiting clot formation. However, they may also increase the risk of bleeding, including intracranial hemorrhage. Other stroke prevention strategies, such as antiplatelet agents and atrial fibrillation ablation, may also be used in selected patients. These strategies may be associated with different risks and benefits compared to anticoagulation. It is important to discuss the risks and benefits of different stroke prevention strategies with a healthcare provider to decide which strategy is best for an individual patient.
