A history of atrial fibrillation and outcomes in chronic advanced systolic heart failure: a propensity-matched study.

Aims: Atrial fibrillation (AF)-associated poor outcomes in heart failure (HF) are often attributed to older age, advanced disease, and comorbidity burden of HF patients with AF. Therefore, we examined the effect of AF on outcomes in a propensity-matched study in which patients with and without AF were well balanced on all measured baseline characteristics.
