Comparison of adverse events after on-pump and off-pump coronary artery bypass grafting in patients with COPD / 中华胸心血管外科杂志

ABSTRACT

Objective:To investigate the difference of adverse events in patients with chronic obstructive pulmonary disease (COPD) who underwent on-pump coronary artery bypass grafting (ONCABG) and off-pump coronary artery bypass grafting (OPCABG).Methods:The clinical data of COPD patients undergoing CABG surgery admitted to Beijing Anzhen Hospital affiliated to Capital Medical University from January 2021 to December 2021 were retrospectively analyzed. According to whether they received cardiopulmonary bypass or not, they were divided into ONCABG group (64 cases) and OPCABG group (154 cases). The preoperative and postoperative clinical data were analyzed. The whole group was divided into 4 subgroups (ON1、ON2、OP1、OP2) according to whether receiving cardiopulmonary bypass or not and FEV160% as the cut-off point, to investigate the difference of postoperative adverse events.Results:A total of 218 patients were included, ranging in age from 45 to 76 years old, with a mean age of (63.81±7.72) years, including 149 males (68.35%). There was no significant difference in the incidence of postoperative adverse events between the ONCABG and OPCABG groups ( P>0.05). In subgroup analysis, the incidence of postoperative pulmonary infection (72.73% vs. 45.65%, P<0.05) and postoperative atrial fibrillation (59.09% vs. 32.61%, P<0.05) was higher in ON1 (FEV1≤60% ONCABG, 22 cases) group than in OP1 (FEV1≤60% OPCABG, 46 cases) group. Conclusion:The incidence of postoperative pulmonary infection and atrial fibrillation in COPD patients with FEV1≤60% was higher in ONCABG than in OPCABG.
