HFpEF was diagnosed from a history of congestive HF and\/or combined criteria of N\u2010terminal pro\u2010brain natriuretic peptide (NT\u2010proBNP) concentration and transthoracic echocardiogram parameters, including average septal\u2010lateral E\/e' and tricuspid regurgitation peak velocity. Ninety\u2010five patients with HFpEF (HFpEF group) were compared with 95 patients without HF (CNT group). Low voltage area (LVA) was defined as an area with a bipolar electrogram of &lt;0.5\u2009mV covering &gt;5% of the total left atrial surface. The primary endpoint was a composite of death from any cause or hospitalization for worsening HF. The secondary endpoint was subclinical HFpEF defined from NT\u2010proBNP concentration and average septal\u2010lateral E\/e' or tricuspid regurgitation peak velocity at 6\u201312 months after the procedure irrespective of the rhythm. Kaplan\u2013Meier curves showed that the primary composite endpoint did not differ between the two groups (mean follow\u2010up period 707\u2009\u00b1\u200975 days, log\u2010rank <jats:italic>p<\/jats:italic>\u2009=\u20090.5330).
