IN atrial fibrillation, stroke, ischemic, cerebral infarction, embolic, peripheral embolism, elder patients The Use of
CHADS2 and CHA(2)DS2-VASc scores
As Prognostic Item
Is better Than
other available scores
To predict risk of stroke and peripheral embolism: c-statistics 0.717 CHADS2 and 0.724 CHA(2)DS2-VASc. Patients categorized as "moderate-risk" were 5.3% with CHA(2)DS(2)-VASc and 49% with CHADS2

IN atrial fibrillation, stroke, ischemic, cerebral infarction, embolic, peripheral embolism, elder patients The Use of

As Prognostic Item
Is equal Than
simple pragmatic rule classifying all patients > 75y as high risk
To all scores were similarly performant (c statistics 0.55-0.60). Moreover, they classified most patients as high risk (67% of patients) and the remaining as moderate risk
