Background

Chronic obstructive pulmonary disease (COPD) is associated with an increased risk of adverse events in patients with atrial fibrillation (AF); however, few data are available on this topic in Asian populations.

Methods and Results

Prospective observational study conducted on patients with AF enrolled in the Asia‐Pacific Heart Rhythm Society (APHRS) AF Registry. The diagnosis of COPD was based on data reported in the case report form by the investigators. Cox‐regression models were used to assess the 1‐year risk of a primary composite outcome of all‐cause death, thromboembolic events, acute coronary syndrome, and heart failure. Analysis on single outcomes and cardiovascular death was also performed. Interaction analysis was used to assess the risk of composite outcome and all‐cause death in different subgroups. The study included 4094 patients with AF (mean±SD age 68.5±12 years, 34.6% female), of whom 112 (2.7%) had COPD. Patients with COPD showed a higher incidence of the primary composite outcome (25.1% versus 6.3%,
P
<0.001), all‐cause death (14.9% versus 2.6%,
P
<0.001), cardiovascular death (2.0% versus 0.6%,
P
<0.001), and heart failure (8.3% versus 6.0%,
P
<0.001). On multiple Cox‐regression analysis, COPD was associated with a higher risk of the primary composite outcome (hazard ratio [HR], 3.17 [95% CI, 2.05–4.90]), all‐cause death (HR, 3.59 [95% CI, 2.04–6.30]), and heart failure (HR, 3.32 [95% CI, 1.56–7.03]); no statistically significant differences were found for other outcomes. The association between COPD and mortality was significantly modified by the use of beta blockers (
P
int
=0.018).

Conclusions

In Asian patients with AF, COPD is associated with worse prognosis. In patients with AF and COPD, the use of beta blockers was associated with a lower mortality.
