Off-pump versus on-pump CABG in high-risk patients: short- and mid-term outcome

During recent years Conventional Coronary Artery Bypass Grafting (cCABG) and Off-Pump Coronary Bypass (OPCAB) have been compared in several randomised and non-randomised studies. Focus has been on postoperative outcome with short-term follow-up in low-risk patients and therefore little is known of the effectiveness of OPCAB in high-risk patients. Furthermore, it is unknown if a potential beneficial short-term outcome is consistent over time.
