Key result
Preoperative insertion of an intra-aortic balloon pump prior to OPCAB was associated with a shorter intensive care stay, decreased acute heart failure, and reduced postoperative mortality.

Does preoperative insertion of an intra-aortic balloon pump improve clinical outcomes in high-risk coronary atherosclerotic disease patients undergoing off-pump coronary artery bypass grafting?
Preoperative insertion of an intra-aortic balloon pump in high-risk patients undergoing off-pump CABG is associated with reduced postoperative mortality, acute heart failure, and intensive care stay.
May support preoperative IABP in high-risk OPCAB; hypothesis-generating pending randomized confirmation.
This study investigated the efficacy and safety of preoperative insertion of an intra-aortic balloon pump (IABP) in high-risk coronary atherosclerotic disease patients undergoing off-pump coronary artery bypass grafting (OPCAB). A total of 232 patients were recruited to the study, of whom 107 underwent percutaneous insertion of an IABP prior to OPCAB. The remaining 125 patients underwent OPCAB alone. Pre-, peri- and postoperative parameters were compared between the two groups. Preoperative insertion of an IABP was associated with a shorter stay in intensive care, decreased incidence of postoperative dialysis and acute heart failure, and a reduction in postoperative mortality compared with OPCAB alone. There were no between-group differences in terms of haematocrit level, number of distal anastomoses, volume of postoperative drainage or incidence of reoperation for bleeding and postoperative stroke/cerebrovascular accident. In conclusion, preoperative insertion of an IABP improved the prognosis of high-risk CAD patients undergoing OPCAB.

Shi et al. (2011) conducted a cohort in High-risk coronary atherosclerotic disease (n=232). Preoperative insertion of an intra-aortic balloon pump (IABP) vs. OPCAB alone was evaluated on Pre-, peri- and postoperative parameters. Preoperative insertion of an intra-aortic balloon pump prior to OPCAB was associated with a shorter intensive care stay, decreased acute heart failure, and reduced postoperative mortality.
