Abstract

Objectives: Prophylactic intra-aortic balloon pump (IABP) insertion is recommended for high-risk patients undergoing coronary artery bypass grafting surgery (CABG). Criteria for high-risk patients benefiting from IABP are unclear. IABP effects on coronary perfusion and afterload might be particularly relevant in patients with critically reduced coronary perfusion and acutely impaired left-ventricular ejection fraction (LVEF), namely patients with acute myocardial infarction (AMI). We analyzed the outcomes of AMI patients undergoing CABG with or without prophylactic IABP.
