Risk factors of new atrial fibrillation after coronary artery bypass grafting / 中国胸心血管外科临床杂志

ABSTRACT

@#Objective    To analyze the risk factors of new-onset postoperative atrial fibrillation (POAF) after coronary artery bypass grafting (CABG). Methods    From September 2011 to October 2013, 1 614 consecutive patients underwent elective coronary artery bypass grafting in Fuwai Hospital. There were 1 281 males and 333 females at average age of 60.3±8.4 years. Holter data recorded for 5 days after operation were collected and analyzed. The risk factors associated with POAF were assessed according to the baseline and intraoperative data, and the positive variables were stratified. Results    A total of 314 patients (19.5%) developed new-onset POAF. The rate of POAF was elevating with the increase of age (P<0.001). Conclusion    Age was an independent risk factor for POAF in patients undergoing elective CABG alone.
