Participants 426
- AF favors formation of intra-atrial thrombi so possibility of thromboembolism should be assessed
- Management: OAC drugs to decrease risk of stroke in AF
Stroke Risk Assessment using CHA2DS2-VASc score
- developed for stratification of stroke risk with AF
- identifies the patient’s associated risk factors
- beneficial to understanding the potential AF treatment management with OAC
| CHA2DS2-VASc Risk | Score |
| CHF or LVEF <40% | 1 |
| Hypertension | 1 |
| Age >75 | 2 |
| Diabetes | 1 |
| Stroke / TIA / Thromboembolism | 2 |
| Vascular disease | 1 |
| Age 65 – 74 | 1 |
| Sex Category: Female | 1 |
| Anticoagulation Recommendation for AF
Based on CHA2DS2-VASc Scoring System |
|
| CHA2DS2-VASc Score | Recommendation |
| ≥ 2 | Oral anticoagulants are recommended |
| 1 | Either anticoagulation, no therapy, aspirin |
| 0 | No antithrombotic therapy |
Bleeding Risk Assessment using HAS-BLED score
- identifies the precautionary measures that should be taken prior to OAC
| Clinical Characteristics | Score |
| Hypertension (Uncontrolled) | 1 |
| Abnormal liver or renal functions (1 point each) | 1 or 2 |
| Stroke | 1 |
| Bleeding | 1 |
| Labile INRs | 1 |
| Elderly (Age > 65) | 1 |
| Drugs (aspirin, clopidogrel, NSAIs, etc) or alcohol
(1 point each) |
1 or 2 |
| HAS-BLED Score | Bleeding Risk (%) |
| 0 | 1 |
| 1 | 2 |
| 2 | 3 |
| 3 | 4 |
| 4 | 9 |
| >5 | 13 |
