Why the study?
Does a history of atrial fibrillation increase the risk of stroke in patients with heart failure and preserved ejection fraction?
Does a history of atrial fibrillation increase the risk of stroke in patients with heart failure and preserved ejection fraction?
In patients with HFpEF, a history of atrial fibrillation is independently associated with a more than twofold increased risk of stroke, highlighting the need for stroke risk assessment in this population.

AF history associated with higher stroke risk in HFpEF; supports stratification but leaves open anticoagulation benefit in this cohort.
Oluleye et al. (2014) studied this question.
