Correct answer: B — The 2024 guidelines adopted CHA₂DS₂-VA, dropping the sex category (Sc) because female sex is a risk modifier rather than an independent stroke risk factor — all other risk components remain unchanged
The 2024 ESC atrial fibrillation guideline moved from CHA₂DS₂-VASc to CHA₂DS₂-VA for thromboembolic risk assessment. The only structural change is removal of the sex category (Sc): female sex is treated as an age-dependent stroke risk modifier, not an independent stroke risk factor. The remaining components are unchanged: chronic heart failure, hypertension, age ≥75 years (2 points), diabetes, prior stroke/TIA/arterial thromboembolism (2 points), vascular disease, and age 65–74 years. Therefore the correct answer is B.
