Values represent the CHADS2 score redistribution applying the CHA2DS2-VASc score. CHADS2 = congestive heart failure (1 point), hypertension (1 point), age ≥75 years (1 point), diabetes mellitus (1 point) and previous stroke/transient ischemic accident (2 points); CHA2DS2-VASc = congestive heart failure (1 point), hypertension (1 point), age ≥75 years (2 points), diabetes mellitus (1 point), previous stroke/transient ischemic accident (2 points), vascular disease (1 point), age 65–75 years (1 point) and female gender (1 point).
