  • Description: <jats:sec xml:lang="en"> <jats:title>Background</jats:title> <jats:p xml:lang="en">Hospitalization for heart failure (HF) is very common in patients with atrial fibrillation (AF). We hypothesized that biomarkers of inflammation can identify patients with AF at increased risk of this important complication.</jats:p> </jats:sec> <jats:sec xml:lang="en"> <jats:title>Methods and Results</jats:title> <jats:p xml:lang="en"> Patients with established AF were prospectively enrolled. Levels of hs‐CRP (high‐sensitivity C‐reactive protein) and interleukin‐6 were measured from plasma samples obtained at baseline. We calculated an inflammation score ranging from 0 to 4 (1 point for each biomarker between the 50th and 75th percentile, 2 points for each biomarker above the 75th percentile). Individual associations of biomarkers and the inflammation score with HF hospitalization were obtained from multivariable Cox proportional hazards models. A total of 3784 patients with AF (median age 72 years, 24% prior HF) were followed for a median of 4.0 years. The median (interquartile range) plasma levels of hs‐CRP and interleukin‐6 were 1.64 (0.81–3.69) mg/L and 3.42 (2.14–5.60) pg/mL, respectively. The overall incidence of HF hospitalization was 3.04 per 100 person‐years and increased from 1.34 to 7.31 per 100 person‐years across inflammation score categories. After multivariable adjustment, both biomarkers were significantly associated with the risk of HF hospitalization (per increase in 1 SD, adjusted hazard ratio [HR], 1.22; 95% CI, 1.11–1.34 for log‐transformed hs‐CRP; adjusted HR, 1.48; 95% CI, 1.35–1.62 for log‐transformed interleukin‐6). Similar results were obtained for the inflammation score (highest versus lowest score, adjusted HR, 2.43; 95% CI, 1.80–3.30; <jats:italic>P</jats:italic> value for trend &lt;0.001). </jats:p> </jats:sec> <jats:sec xml:lang="en"> <jats:title>Conclusions</jats:title> <jats:p xml:lang="en">Biomarkers of inflammation strongly predicted HF hospitalization in a large, contemporary sample of patients with AF.</jats:p> </jats:sec> <jats:sec xml:lang="en"> <jats:title>Registration</jats:title> <jats:p xml:lang="en"> URL: <jats:ext-link xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="uri" xlink:href="https://www.clinicaltrials.gov">https://www.clinicaltrials.gov</jats:ext-link> ; Unique identifier: NCT02105844. </jats:p> </jats:sec>
