Association between Preoperative Cardiac Left Ventricular Dysfunction and Perioperative Intraaortic Balloon Pump in Patients Undergoing Off-Pump Coronary Artery Bypass Surgery

摘要

Background: Prophylactic use of intraaortic balloon pump (IABP) reduces hospital mortality in patients with left ventricular (LV) systolic dysfunction undergoing coronary artery bypass surgery (CABG); however, its association in patients with LV diastolic dysfunction is unclear. This retrospective study investigated the association between preoperative LV function and perioperative use of IABP in patients undergoing off-pump CABG (OPCAB) at a university hospital.
