Why the study?
Anticoagulation indications remain debated in AF patients with a CHA2DS2-VASc score of 1, as a score of 1 is derived from varying risk factors that may represent different thromboembolic risks.
Does the specific risk factor driving a CHA2DS2-VASc score of 1 affect the thromboembolic risk in patients with atrial fibrillation not treated with anticoagulants?
Does the specific risk factor driving a CHA2DS2-VASc score of 1 affect the thromboembolic risk in patients with atrial fibrillation not treated with anticoagulants?
In AF patients with a CHA2DS2-VASc score of 1, the specific risk factor driving the score significantly affects thromboembolic risk, with age 65-74 conferring the highest risk.

May inform nuanced anticoagulation decisions for CHA2DS2-VASc score of 1; extends risk stratification beyond aggregate score.
