B\u2010type natriuretic peptide (BNP), midregional proatrial natriuretic peptide (MR\u2010proANP), apelin, and interleukin\u20106 (IL\u20106) were assayed at baseline, 3 months, 6 months, and 12 months. The primary end point, analyzed per\u2010protocol, was changed from baseline at 12 months.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Of 52 recruited patients, 24 ablation and 25 rate control subjects were followed to 12 months. After 1.2 \u00b1 0.5 procedures, sinus rhythm was present in 22 (92%) ablation patients; under rate control, rate criteria were achieved in 23 (96%) of 24 patients remaining in AF. At 12 months, MR\u2010proANP fell significantly in the ablation arm (\u2013106.0 pmol\/L, interquartile range [IQR] \u2013228.2 to \u201360.6) compared with rate control (\u201328.7 pmol\/L, IQR \u201369 to +9.5, P = 0.028). BNP showed a similar trend toward reduction (P = 0.051), with no significant difference in apelin (P = 0.13) or IL\u20106 (P = 0.68). Changes in MR\u2010proANP and BNP correlated with peak VO<jats:sub>2<\/jats:sub> and ejection fraction, and MR\u2010proANP additionally with quality\u2010of\u2010life score.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Catheter ablation, compared with rate control, in patients with heart failure and persistent AF was associated with significant reduction in MR\u2010proANP, which correlated with physiological and symptomatic improvement. Ablation\u2010based rhythm control may induce beneficial cardiac remodeling, unrelated to changes in inflammatory state. This may have prognostic implications, which require confirmation by event end point
