What is the CHA2DS2-VASc Score?
Jun 5, 2019 5:46pm

The CHA2DS2-VASc score assigns points to a series of clinical observations in patients with non-valvular atrial fibrillation (AFIB ). CHA2DS2-VASc scores are used to predict the risk of ischemic stroke.

The score is computed as follows:

  • Congestive heart failure or left ventricular systolic dysfunction: 1 point
  • Hypertension:  BP consistently above 140/90 mmHg or treated hypertension on medication: 1 point
  • Age ≥75 years: 2 points
  • Diabetes mellitus: 1 point
  • Stroke, VTE , TIA : 2 points
  • Vascular disease; PAD , MI, aortic plaque: 1 point
  • Age 65–74: 1 point
  • Sex category, female: 1 point

The CHA2DS2-VASc score translates to stroke risk as follows...

0: 0%
1: 1.3%
2: 2.2%
3: 3.2%
4: 4%
5: 6.7%
6 and 7: 9.8%
8: 12.5%
9: 15.2%

Stroke rates vary by study setting, population, and demographic and therapeutic efficacy varies by clinical trial design, but In general, a stroke risk of 2% or over dictates anticoagulant therapy according to international guidelines.
