Abstract：Objective To investigate the effect of pulmonary artery floating catheter monitoring on the prognosis of coronary artery bypass grafting(CABG)in elderly patients.Methods A total of 711 elderly patients undergoing elective CABG admitted to Beijing Anzhen Hospital,Capital Medical University from January to December 2019 were retrospectively analyzed.Patients were divided into PAC group(278 cases)and non-PAC group(433 cases)according to whether pulmonary artery floating catheter was inserted during the operation.The incidence of postoperative adverse events was compared between the two groups.Multivariate Logistic regression analysis was used to evaluate the effect of pulmonary artery floating catheter placement on the prognosis of elderly patients undergoing CABG.Results There were 11 in-hospital deaths in 711 elderly patients undergoing CABG.Among them,there were 3 cases(1.1％)in PAC group and 8 cases(1.8％)in non-PAC group.Univariate analysis showed that there were no significant differences in the incidence of in-hospital death,myocardial infarction,postoperative new-onset atrial fibrillation,cerebrovascular accident,acute renal failure,reoperation due to bleeding,and infection between the two groups(all P＞0.05).After adjusting for confounding factors by Logistic regression model,the in-hospital mortality of PAC group was lower than that of non-PAC group(adjusted odds ratio:0.199,95％confidence interval:0.042-0.939,P=0.041).However,there were no significant differences in myocardial infarction,postoperative new-onset atrial fibrillation,cerebrovascular accident,acute renal failure,reoperation due to bleeding and infection between the two groups(all P＞0.05).Conclusion In elderly patients undergoing CABG,the use of intraoperative pulmonary artery floating catheter is beneficial in improving in-hospital mortality.
