The CHA2DS2-VASc score is used to predict thromboembolic risk in atrial fibrillation. CHA2DS2=(Congestive heart failure, Hypertension, Age (>65=1 point, >75=2 points), Diabetes, previous Stroke, or transient ischemic attack (2 points)); VASc=vascular disease (peripheral arterial disease, previous myocardial infarction, aortic atheroma), and sex category (female gender) is also included in the scoring system. CHA2DS2-VASc score was determined at the time of diagnosis.
International Classification of Primary Care codes were used.
