- Components: Congestive heart failure (1), Hypertension (1), Age ≥75 years (2), Diabetes (1), Stroke/TIA/thromboembolism (2). – Rationale: Simpler, but less precise for risk stratification. – CHA2DS2-VASc (updated scoring system):
- Components: Congestive heart failure/LVEF ≤40% (1), Hypertension (1), Age ≥75 years (2), Diabetes (1), Stroke/TIA/thromboembolism (2), Vascular disease (1), Age 65–74 years (1), Sex category (female, 1). – Rationale: More comprehensive, includes additional risk factors (vascular disease, age 65–74, sex), improving risk stratification. Key Differences:
- CHA2DS2-VASc adds 3 risk factors (vascular disease, age 65–74, female sex).
