Correct answer: C — 5

The 2024 ESC AF Guidelines introduce the CHA2DS2-VA score, which removes sex as a scoring factor. Scoring: C (HF) = 0, H (hypertension) = 1, A2 (age 75 or above) = 0 (he is 68), D (diabetes) = 1, S2 (stroke/TIA) = 2, V (vascular disease) = 0, A (age 65-74) = 1. Total = 1+1+2+1 = 5. This score places him at high thromboembolic risk and oral anticoagulation with a DOAC is strongly indicated.
