Off-Pump Versus On-Pump: Long-Term Outcomes After Coronary Artery Bypass in a Veteran Population

摘要

Objectives: The authors sought to investigate long-term outcomes after revascularization with and without use of cardiopulmonary bypass and hypothesized that off-pump would be comparable with on-pump. The primary outcome of interest was survival, and secondary outcomes were need for reintervention for revascularization or new diagnosis of myocardial infarction occurring any time after surgery during the 8- to 12-year follow-up period.
