Predicting bleeding and stroke risk in new Afib

There are several risk indices for predicting stroke and bleeding risk in patients with AFib, but it is not clear which are better. In this large cohort of patients with new onset Afib, researchers compared the ROC of 2 bleeding risk indices (HAS-BLED and HEMORR2HAGES) and 2 stroke risk indices (CHADS2 and CHA2DS2VASc). They found the ROC for the stroke risk indices were about the same (0.66 and 0.67 respectively), as well as for the bleeding indices (0.60 for both). Either of these predictive models perform about the same, but the CHADS2 and the HAS-BLED have the advantage of being simpler to calculate / use (abstract)
