    Abstract:
    BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a common chronic disease, being associated with both high rates of morbidity and mortality. Similarly, atrial fibrillation (AF) is associated with a higher risk of both cardiovascular (CV) events and overall mortality. The AF and COPD often coexist, but the impact of COPD on prognosis in European AF patients is unknown. METHODS: We evaluated COPD prevalence in patients enrolled in the EURObservational Research Programme Pilot Survey on Atrial Fibrillation Registry Pilot Phase. Clinical factors associated with COPD and adverse outcomes at 1-year follow-up were determined. RESULTS: In the overall cohort, a diagnosis of COPD was recorded in 339 (11.0%) of AF patients. The AF patients with COPD were more burdened with risk factors and comorbidities, including diabetes mellitus (P < .0001) and chronic heart failure (P < .0001). β-Blockers were less likely to be prescribed to patients with COPD (P = .0007). On follow-up, AF patients with COPD had a higher risk of both CV death and all-cause death (both P < .0001), as well as for the composite outcome of any thromboembolic event/bleeding /CV death (P = .0003). Cox regression analysis found that COPD was independently associated with an increase in all-cause death (hazard ratio, 1.55; 95% CI 1.05-2.28; P = .0269). CONCLUSIONS: Chronic obstructive pulmonary disease is highly prevalent in European AF patients, and is associated with higher rates of CV death, all-cause death, and the composite outcome of any thromboembolic event/bleeding/CV death. The presence of COPD in AF patients was independently associated with all-cause death in AF patients.
