A comparative analysis of intra-aortic balloon pump in off-pump patients undergoing coronary artery bypass grafting at different perioperative stages

摘要

Background Intra-aortic balloon pump(IABP) has been widely used at present.We can use it at different stages of perioperative period in off-pump coronary artery bypass grafting(CABG).However,when to used it was seldom confirmed.Methods From January 2008 to June 2012,the 89 coronary heart disease(CHD) patients accepted implantation of IABP at different stages of off-pump CABG,preoperative and postoperative ventricular systolic function,left ventricular remodeling situation and the changes of myocardial enzymes were evaluated.Results All the patients had left heart insufficiency and multivessel disease.Their postoperative left ventricular systolic function and ventricular remodeling were significantly improved while myocardial enzymes decreased with preoperative interventional implantation of IABP.The perioperative mortality was 7.86%(7 /89).No patients had complication of IABP.Conclusion Earlier IABP implantation at preoperation is useful to improve heart function,improve the tolerability of surgery,reduce the incidence of postoperative low cardiac output syndrome(LCOS) and decrease the mortality.
