Abstract

Background: The elderly population (age >70 years) incurs greater mortality and morbidity following CABG. Off-pump coronary artery bypass (OPCAB) may mitigate these otucomes. A retrospective analysis of the results of OPCAB in this population was performed. Methods: We reviewed the Australian and New Zealand Society of Cardiac and Thoracic Surgeons (ANZSCTS) database for elderly patients (n=12697) undergoing isolated CABG surgery and compared the on-pump coronary artery bypass (ONCAB) (n=11676) with OPCAB (n=1021) technique. Preoperative and intraoperative risk factors, and postoperative outcomes were analysed. Survival analyses was performed after cross-matching the database with the national death registry to identify long-term mortality. Results: High-risk patients were more prevalent in the ONCAB group (p
