Background: Oral anticoagulation is suggested in patients with atrial fibrillation and a CHADS-VASc score ≥1 (congestive heart failure, hypertension, age ≥75 years, diabetes, stroke, vascular disease, age 65-74 years, and sex score). To assess granular differences within CHADS-VASc 1, the incidence of arterial thromboembolism according to CHADS-VASc 1 subgroups was examined.
Methods: The Danish National Patient Registry and the Danish Prescription Registry were linked on a nationwide level to identify patients with atrial fibrillation from 2000 to 2021 without oral anticoagulation and categorized according to CHADS-VASc score: CHADS-VASc 0 (male and female subjects); CHADS-VASc 1 (hypertension, heart failure, diabetes, vascular disease, and age 65-74 years); or CHADS-VASc 2 (age ≥75 years without other risk factors).
