The endpoints were AF recurrence at 1\u2009year, changes in symptomatic and image-based functional status, and changes in BNP levels from baseline to 1\u2009year. In the HFpEF group, AF recurred in 48 patients (16.4%) and 278 patients (94.8%) had sinus rhythm at 1\u2009year; these values were comparable with those in the other groups. Significant improvement was observed in the left atrial diameter, LVEF, and New York Heart Association functional class in the HFpEF and HFmrEF + HFrEF groups. The BNP level significantly decreased irrespective of the index rate control status, and freedom from AF recurrence was an independent predictor of HF remission, defined as BNP &amp;lt;100\u2009pg\/mL at 1\u2009year, in the HFpEF group.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Catheter ablation is highly feasible for restoring sinus rhythm in non-paroxysmal AF with coexisting HFpEF, thereby improving cardiac function and BNP levels.
