What is the practical patient management algorithm for stroke prevention in patients with AF?
The approach to stroke prevention in patients with AF can be simplified into a simple 3-step algorithm (Fig 4). The initial step is to determine the risk of stroke. As noted in the Stroke Risk in AF section, risk scores for stroke in patients with AF lack specificity, and are therefore not clinically useful in identifying and categorizing high-risk patients. The next step is to determine the type of antithrombotic therapy to be used. The type of therapy used should be based on patient preference, risk factors, and the availability of resources. Finally, the patient should be monitored to ensure the appropriate dosing and effectiveness of the therapy. This may involve self-monitoring and/or regular visits to the doctor.
