Does the Number of Grafts Influence Surgeon Choice and Patient Benefit of Off-Pump Over Conventional On-Pump Coronary Artery Revascularization in Multivessel Coronary Artery Disease?

This study demonstrates that surgeons tend to perform OPCABG for patients requiring 1 to 3 grafts and ONCABG for those requiring 4 to 7 grafts. Off-pump CABG is associated with reduced adjusted risk of adverse outcomes compared with ONCABG. This benefit is consistent for patients requiring 1 to 3 or 4 to 7 grafts.
