Atrial fibrillation (AF) is often associated with multiple traditional comorbidities
such as hypertension, heart failure, diabetes and obesity.
1
Besides sleep apnea,
2
chronic obstructive pulmonary disease (COPD) is another emerging respiratory risk
factor for AF. COPD is associated with increased AF incidence, AF progression and
reduced treatment response to rhythm control strategies such as cardioversion, antiarrhythmic
drug treatment and catheter ablation.

In addition, COPD is associated with higher symptom burden and worse quality of life.
COPD is also associated with increased hospital admissions and all-cause mortality
in AF patients.

Importantly, this liaison between AF and COPD is not merely the result of shared
risk factors, but there is increasing evidence that direct COPD-related mechanisms
contribute to AF onset and AF progression. Gas exchange abnormalities (i.e. hypoxaemia
and hypercapnia) may promote atrial remodelling by hypoxemia-induced systemic inflammation
and pulmonary hypertension. As a consequence, right ventricular hypertrophy and diastolic
dysfunction may induce further cardiac remodelling.

Also, dynamic hyperinflation with subsequent thoracic pressure swings is hypothesized
to increase sympathetic nerve activity. This complex interplay of mechanisms of cardiac
remodelling and transient sympathetic nerve activity creates a complex and dynamic
arrhythmogenic substrate for AF in patients with COPD.
