非体外循环冠状动脉搭桥术后新发房颤的影响因素分析

目的:分析非体外循环冠状动脉搭桥(OPCABG)术后新发房颤的影响因素。方法:选取2019年1月—2019年8月择期行OPCABG术患者209例,术后住院期间确诊新发房颤患者36例（新发房颤组），未新发房颤患者173例（非房颤组）。比较两组患者的临床资料,进一步采用Logistic回归分析OPCABG术后新发房颤的影响因素。结果:新发房颤组右冠状动脉近段狭窄≥75%的比例、主动脉内球囊反搏（IABP）辅助率明显高于非房颤组（均P<0.05）；两组间其他临床资料差异均没有统计学意义（均P>0.05）；采用Logistic回归分析:右冠状动脉近段狭窄≥75%（OR=3.999，95%CI:2.072～19.753，P<0.00１），IABP辅助率（OR=6.397，95%CI:2.072～19.753，P<0.001）是OPCABG术后新发房颤的影响因素。结论:右冠状动脉近段狭窄≥75%，围术期需要IABP辅助是OPCABG患者术后新发房颤的影响因素。

Influencing factors of new-onset atrial fibrillation after off-pump coronary artery bypass grafting surgery

Objective: To analyze the influencing factors of new-onset atrial fibrillation after off-pump coronary artery bypass grafting（OPCABG） suryery. Methods: A total of 209 patients who underwent elective OPCABG surgery from January 2019 to August 2019 were selected. During postoperative hospitalization，36 patients（new-onset atrial fibrillation group） were diagnosed with new-onset atrial fibrillation， and 173 patients（non-new atrial fibrillation group） were not. Clinical data of the two groups were collected and compared and the influencing factors of new-onset atrial fibrillation after OPCABG surgery were analyzed by Logistic regression. Results: The rate of proximal stenosis of right coronary artery（more than 75%） and intra-aortic balloon pump（IABP） supporting the new-onset atrial fibrillation group were significantly higher than those in the non-new atrial fibrillation group，and the difference was statistically significant（all P<0.05）. There was no statistically significant difference in other clinical data between the two groups（P>0.05）.Logistic regression analysis showed that proximal stenosis of right coronary artery（more than 75%）（OR=3.999，95%CI:2.072-19.753，P<0.001） and IABP auxiliary rate（OR=6.397，95%CI:2.072-19.753，P<0.001） were the influencing factors for the new occurrence of atrial fibrillation after OPCABG surgery. Conclusion: The proximal stenosis of right coronary artery（more than 75%） and the need for IABP support during perioperative period are the influencing factors for the patients with new-onset atrial fibrillation after off-pump coronary artery bypass grafting surgery.
