  • Stroke Risk

  • CHA2DS2-VASc Score of 0: Low Risk. May not require anticoagulation.
  • CHA2DS2-VASc Score of 1: Low-moderate Risk. Should consider Aspirin or Anticoagulation.
  • CHA2DS2-VASc Score of 2 or greater: Moderate-high Risk. Anticoagulation, except contraindications.

Are Oral Anticoagulation necessary?

Every patiente with Atrial Fibrillation or Atrial Flutter and CHA2DS2-VASc Score of 2 or greater should receive oral Anticoagulants, except for contraindications.

The decision of administering anticoagulants to the patient is irrespective of the type of Atrial Fibrillation suffered by the patient; both paroxysmal and permanent AF present the same stroke risk.

In patients with a CHA2DS2-VASc score of 1, anticoagulant or antiplatelet treatment could be administered; whereas in patients with no risk factors (CHA2DS2-VASc score of 0) anticoagulants are not recommended, antiplatelet treatment could be administered by doctor’s decision.
