Calculated CHA2DS2-VASc risk score: points
Outcome stratification
Conditional information
Result interpretation
This model calculates stroke risk for patients with atrial fibrillation. The CHA2DS2-VASc risk score (acronym: Birmingham 2009) fared marginally better (C-statistic, 0.606) than CHADS(2). However, those classified as low risk by the CHA2DS2-VASc and NICE schema were truly low risk with no TE events recorded, whereas TE events occurred in 1.4% of low-risk CHADS(2) subjects. When expressed as a scoring system, the CHA2DS2-VASc showed an increase in TE rate with increasing scores (P value for trend = .003).
Calculations alone should never dictate patient care, and are no substitute for professional judgement. See our full disclaimer.
