Interactive CHA₂DS₂-VASc Score calculator for atrial fibrillation stroke risk. Requires the calculator gadget.
Usage: {{CHA2DS2VASc Calculator}}
| Criteria | No (0) | Yes |
|---|---|---|
| Congestive heart failure (or LVEF ≤40%) | 1 | (+1) |
| Hypertension | 1 | (+1) |
| Age ≥75 years | 1 | (+2) |
| Diabetes mellitus | 1 | (+1) |
| Stroke/TIA/thromboembolism | 1 | (+2) |
| Vascular disease (prior MI, PAD, aortic plaque) | 1 | (+1) |
| Age 65–74 years | 1 | (+1) |
| Sex category (female) | 1 | (+1) |
| CHA₂DS₂-VASc Score | / 9 | |
| Interpretation | |
|---|---|
| 0 | Low Risk — 0.2% annual stroke risk (males). Anticoagulation generally not recommended. |
| 1 | Low-Moderate Risk — 0.6% annual stroke risk (males). Consider anticoagulation (esp. if not due to female sex alone). |
| ≥2 | Moderate-High Risk — ≥2.2% annual stroke risk. Oral anticoagulation recommended. |
