The incidence of atrial fibrillation in the aging population continues to increase in frequency and predisposes patients to an increased risk for stroke. Assessment of risk for stroke is a significant and independent risk factor for stroke. Approximately 15% of all patients experiencing a stroke also have been diagnosed with atrial fibrillation.
35 % of patients with atrial fibrillation will have a stroke if untreated. These combined statistics suggest that the incidence of a stroke is five times more likely in patients with atrial fibrillation. (National Stroke Association).
By using a CHADS 2 scale, patients can be assessed for the risk for stroke, particularly in patients with atrial fibrillation, provides a consistent rubric for assessing the patient’s need for monitoring, anticoagulation and follow-up.
