The emerging role of inflammation in atrial fibrillation and the potential of anti-inflammatory interventions We read with considerable interest the article by Engelmann and Svendsen1 provid-ing a concise overview of the current know-ledge about the association of inflammation with atrial fibrillation (AF). A continuously increasing number of investigations examine the role of inflammation in AF. Interestingly, two recent studies indicated that C-reactive protein relates to the left atrial size and AF duration before cardioversion, providing evi-dence of an association between inflam-mation and atrial structural remodelling.2,
