The CHA2DS2VASC score predicts annual stroke risk among persons with atrial fibrillation using the following risk factors: congestive heart failure, hypertension, age [>65 years = 1 point; >75 years = 2 points], diabetes, previous stroke or transient ischemic attack [2 points], and vascular disease.
