CHA₂DS₂-VA

Thromboembolic risk factors in AF, without a sex-related point.

CHA₂DS₂-VA

Principle

Assessment of thromboembolic risk factors in atrial fibrillation.

Scope

Adult atrial fibrillation. ESC 2024 CHA₂DS₂-VA variant, distinct from CHA₂DS₂-VASc. The score alone is insufficient to decide on anticoagulation; hypertrophic cardiomyopathy and cardiac amyloidosis are special situations independent of the total.

Interpretation limits

ESC 2024: 1 point is a risk indicator to consider, ≥2 an indicator of high risk. No individual risk in %, prescription or implicit conversion from VASc; reassess as the clinical situation evolves.

Formula and logic

C(1) + H(1) + exclusive age(0/1/2) + D(1) + S₂(2) + V(1). Total 0–8. No sex-related point.

Interpretation

0–0
No scored factor
1–1
One scored factor · assess risk
2–8
Indicator of high risk
0–0
No score factor present; assess special situations.
1–1
ESC2024: consider oral anticoagulation.
2–8
ESC2024: oral anticoagulation recommended.
