Key result
Atrial fibrillation in hospitalized heart failure patients was associated with an increased risk of 1-year mortality (HR 1.19; 95% CI 1.03-1.36).

Does the presence of atrial fibrillation increase mortality in patients hospitalized for heart failure?
Hazard Ratio: 1.19 (95% CI 1.03–1.36)
Atrial fibrillation is present in a third of hospitalized heart failure patients and is independently associated with a 19% increased risk of 1-year mortality.
Shotan et al. (2009) conducted a cohort in Heart failure (n=4,102). Atrial fibrillation vs. No atrial fibrillation was evaluated on 1-year mortality (HR 1.19, 95% CI 1.03-1.36). Atrial fibrillation in hospitalized heart failure patients was associated with an increased risk of 1-year mortality (HR 1.19; 95% CI 1.03-1.36).
