• The risk versus benefit for assessment of initiating anticoagulation can be calculated by using validated calculations, such as CHA2DS2-VASc for stroke risk, and HAS-BLED for bleeding risk.
• The recommendation is to initiate oral anticoagulation if the CHA2DS2-VASc stratification score is 2 or greater.
• CHA2DS2-VASc score stands for: congestive heart failure, hypertension, age greater than 75 (2 points), diabetes mellitus, stroke history, vascular disease, age 65-74 (1 point), and female gender. One point is given if any of these categories are present, except for age over 75, where two points are given.
• CHA2DS2-VASc evaluates ischemic stroke risk in patients with atrial fibrillation. This patient has a history of hypertension, diabetes mellitus, stroke history, age of 65, and is female, giving her a total score of 6.
