Overview
The CHA2DS2-VASc score predicts clinical risk of stroke and thromboembolism in atrial fibrillation[1].
| Feature | Score if present |
|---|---|
| Congestive Heart Failure | 1 |
| Hypertension | 1 |
| Age ≥ 75 years | 2 |
| Age between 65 and 74 years | 1 |
| Stroke/TIA/TE | 2 |
| Vascular disease (previous MI, peripheral arterial disease or aortic plaque) | 1 |
| Diabetes mellitus | 1 |
| Female | 1 |
Before bleeding risk evaluated score of 0 recommends no antithrombotic therapy and 2 or more antithrombotic therapy. A score of 1 recommends either antithrombotic or antiplatelet therapy. Consider a risk of bleeding assessment such as the HAS-BLED score before anticoagulation.
