However, substantial atrial fibrillation (AF) recurrence is common during follow\u2010up.

Patients were followed up for AF recurrence for 1 year.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 19 patients of the 72 experienced AF recurrence. The level of postoperative HMGB1 (HMGB1post) was higher in the AF recurrence group than in the AF non recurrence group (<jats:italic>p<\/jats:italic>\u2009=\u2009.03). However, no differences were noted in the levels of other biomarkers such as preoperative high\u2010sensitivity C\u2010reactive protein (hs\u2010CRP), postoperativehs\u2010CRP, and preoperative HMGB1 between the two groups. Multiple logistic regression analysis revealed that a higher level of serum HMGB1post was associated with AF recurrence (odds ratio: 5.29 [1.17\u201323.92], <jats:italic>p<\/jats:italic>\u2009=\u2009.04). Receiver operating characteristic analysis revealed that HMGB1post had a moderate predictive power for AF recurrence (area under the curve: 0.68; sensitivity: 72%; and specificity: 68%). The 1\u2010year AF\u2010free survival was significantly lower in patients with a high HMGB1post level than in those with a low HMGB1post level (hazard ratio: 3.81 [1.49\u20139.75], <jats:italic>p<\/jats:italic>\u2009=\u2009.005).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>In pAF patients who under went CBA, the level of HMGB1 after CBA was associated with AF recurrence and demonstrated a moderate predictive power.
