Newly diagnosed atrial fibrillation and hospital utilization in heart failure: a nationwide cohort study.

ABSTRACT:

Aims

Atrial fibrillation (AF) constitutes a major burden to health services, but the importance of incident AF in patients with heart failure (HF) is unclear. We examined the associations between incident AF and hospital utilization in patients with HF.

Methods and results

In a nationwide matched-cohort study of HF patients, we identified patients diagnosed with incident AF between 2008 and 2018 in the Danish Heart Failure Registry (N = 4463), and we compared them to matched referents without AF (N = 17 802). Incident AF was associated with a multivariable-adjusted 4.8-fold increase (95% CI 4.1-5.6) and 4.3-fold increase (95% CI 3.9-4.8) in the cumulative incidence of inpatient and outpatient contacts within 30 days, respectively. At 1 year, the cumulative incidence ratios w
