In-Depth Guide & Mathematical Methodology

❤️ Clinical Anticoagulation Indications (ESC/AHA Guidelines)

Score 0 (Men) / 1 (Women): Low risk. No oral anticoagulation recommended.

Score 1 (Men): Moderate risk. Consider oral anticoagulation (DOAC preferred over Warfarin).

Score ≥ 2 (Men) / ≥ 3 (Women): High risk. Oral anticoagulation strongly indicated.
