Impact of Heart Failure Type on Thromboembolic and Bleeding Risk in Patients with Atrial Fibrillation on Oral Anticoagulation

Heart failure (HF) increases stroke risk in atrial fibrillation (AF) patients. Differential impact of HF category on thromboembolic and bleeding risk in AF patients on oral anticoagulation (OAC) is unknown. We used Medicare data for beneficiaries with new AF diagnosed between 2011 and 2013 to identify patients with HF with reduced ejection fraction (HFrEF), HF with preserved ejection fraction (HFpEF), and no HF. The primary endpoint of admission for ischemic stroke was evaluated using Cox proportional hazards regression models that controlled for patient demographics, comorbidities (including CHA2DS2-VASc and HASBLED scores), and OAC use as a time-dependent covariate.
