CHADS2 risk score assigns over one-third of stroke patients to low or intermediate stroke risk


In contrast, a CHA2DS2-VASc score of 0 identifies a subgroup of patients with very low stroke risk unlikely to benefit from anticoagulation treatment.  The present study tested stroke risk stratification schemes for identifying patients with very low stroke risk who may not benefit from oral anticoagulation.

Results from the AFNET patient registry were presented at ESC congress 2013
