Net Benefit of Antithrombotic Therapy in AF and CKD
Net Benefit of Antithrombotic Therapy in AF and CKD
We have found that among AF patients, CKD was associated with a higher risk of stroke/TE across stroke risk (CHA2DS2-VASc) strata, most notably among RRT patients. In RRT patients with CHA2DS2-VASc score ≥2, warfarin was associated with a net clinical benefit, as it was associated with a lower risk of all-cause mortality. In non-end-stage CKD patients with CHA2DS2-VASc score ≥2, warfarin was associated with a net clinical benefit, as it was associated with a lower risk of all-cause mortality, a lower risk of cardiovascular death, and a lower risk of the composite outcome of fatal stroke/fatal bleeding, respectively. These observations provide guidance for the optimal use of antithrombotic therapy in AF patients with CKD.
