What score is considered the maximum in the CHA2DS2-VASc assessment?

  1. 6

  2. 8

  3. 7

  4. 9

The correct answer is: 9

The CHA2DS2-VASc score is a clinical tool used to assess the risk of stroke in patients with atrial fibrillation, helping healthcare providers determine whether anticoagulation therapy is indicated. The scoring system assigns points based on several risk factors: - Congestive heart failure (1 point) - Hypertension (1 point) - Age 75 years or older (2 points) - Diabetes mellitus (1 point) - Previous stroke or transient ischemic attack (TIA) (2 points) - Vascular disease (1 point) - Age 65-74 years (1 point) - Sex category (female) (1 point) The maximum score possible in the CHA2DS2-VASc assessment is 9. This is calculated by assigning points for the highest risk factors, which include previous stroke or TIA (2 points), age 75 or older (2 points), and the cumulative points from additional factors, such as congestive heart failure and vascular disease, among others. Understanding this scoring system is crucial for clinicians to appropriately stratify stroke risk and guide treatment decisions effectively.
