Characterizing atrial fibrillation in patients with and without heart failure across the ejection fraction spectrum: Incidence, prevalence, and treatment strategies.

ABSTRACT:

Aims

Heart failure (HF) and atrial fibrillation (AF) often coexist. We explored AF incidence, prevalence, and treatment strategies in patients with versus without HF across the ejection fraction (EF) spectrum.

Methods and results

We analysed patients with HF from the Swedish HF Registry (1 December 2005-31 December 2021), matched 1:1 by sex, age, and county of residence to patients without HF from Statistics Sweden. Two study cohorts were derived (i) to assess AF prevalence and treatments, and (ii) to evaluate AF incidence and related predictors. Overall, 195 106 patients were considered, 50% of them with HF (of whom 54% with HF with reduced [HFrEF], 23% mildly reduced [HFmrEF], and 23% with preserved EF [HFpEF]). From 2006 to 2021, AF prevalence increased in both patients w
