CHADSVASc Score - Stroke Risk in Atrial Fibrillation



A clinical mnemonic to estimate stroke risk in atrial fibrillation.  A higher total score indicates a greater stroke risk and supports decisions regarding anticoagulation therapy.



C  	Congestive heart failure 

H 	Hypertension 

A2 	Age ≥ 75 (2 points)

D 	Diabetes mellitus

S2	Stroke / TIA / Thromboembolism

V	Vascular disease (MI, PAD, aortic plaque)

A 	Age 65–74 (1 point)

Sc 	Sex Category female



Score - Yearly Stroke Risk:

0 points - 0.2 %

1 point - 0.6 % 

2 points - 2.2 %

3 points - 3.2 %

4 points - 4.8 %

5 points - 7.2 %

6 points - 9.7 %

7 points - 11.2 %

8 points - 10.8 %

9 points - 12.2 %
