Abstract：Objective To discuss the risk factors of new-onset postoperative rapid atrial fibrillation (RAF) in elderly patients after non-cardiac surgery, and provide the evidence for preventing and treating RAF. Methods The elderly patients aged over 60 undergone non-cardiac surgeries (n=1289, male 685, female 604, aged from 60 to 91 and average age=72.8±9.6) were chosen from Jun. 2007 to Jun. 2014. They were divided into RAF group (n=102) and non-RAF group (n=1187) according to whether or not new-onset RAF occurred. The data (including medical history and medication) were collected from the patients. The incidence of cardiac death [sudden cardiac death, acute myocardial infarction (AMI) and acute decompensated heart failure (ADHF)] was followed up after the surgery for 1 m. Results The percentages of elder (over 75), diabetes history, chronic cardiac insufficiency history, moderately severe lung function impairment history, preoperative kaliopenia and thoracotomy increased in RAF group compared with non-RAF group (all P<0.05). The results of multi-factor regression analysis showed that age over 75 (OR=7.661, 95%CI: 3.886~15.105), diabetes history (OR=30.22, 95%CI: 4.328~277.5), chronic cardiac insufficiency history (OR=29.34, 95%CI: 8.149~105.6), moderately severe lung function impairment history (OR=8.04, 95%CI: 2.858~22.61), preoperative kaliopenia (OR=6.58, 95%CI: 4.340-12.00) and thoracotomy (OR=2.31, 95%CI:0.935~13.74) were risk factors of new-onset postoperative RAF. During 1-month follow up period, the survival rate of cardiac death event-free was significantly lower in RAF group than that in non-RAF group (P=0.0117). Conclusion Age over 75, diabetes, chronic cardiac insufficiency history, moderately severe lung function impairment history, preoperative kaliopenia and thoracotomy are risk factors of new-onset postoperative RAF in elderly patients after non-cardiac surgery, which should be prevented for reducing RAF occurrence.
