Abstract

Objectives: The benefit of preoperative Intra-Aortic Balloon Pump (IABP) implantation in high-risk cardiac surgery patients is still debated. The role of preoperative IABP insertion in Acute Myocardial Infarction (AMI) patients without Cardiogenic Shock (CS) undergoing Off-Pump Coronary Artery Bypass Grafting (OPCAB) remains unknown. This study aimed to determine the efficacy and safety of the preoperative IABP insertion in those patients undergoing OPCAB.Methods: A total of 421 consecutive AMI patients without CS who underwent isolated OPCAB were enrolled in this retrospective observational propensity score-matched analysis study. Patients who received IABP before OPCAB (the IABP group, n=157) were compared to those who had not (control group, n=264). The 30-day postoperative survival, postoperative complications, and postoperative hospital length of stay were compared between the 2 groups.Results: Ninety-nine pairs of patients were matched. The preoperative IABP did not show a 30-day postoperative survival benefit compared to the control group (hazard ratio, 0.9; 95% Confidence Interval [CI], 0.2-4.2; P=0.92). Patients with preoperative IABP were more likely to have short postoperative lengths of stay (8 days versus 10 days, P=0.02) and decreased total days in the hospital (median days: 18.2 vs. 21.8, P=0.02) compared to patients without balloon pumps.Conclusion: Preoperative IABP insertion in AMI patients without CS undergoing OPCAB improved convalescence as shown by significantly shorter postoperative lengths of hospital stay.
