Impact of off-pump techniques on sex differences in early and late outcomes after isolated coronary artery bypass grafts.

Background: Off-pump coronary artery bypass graft surgery (OPCAB) is associated with lower early mortality and benefits women disproportionately. The objective of this study was to assess the impact of off-pump techniques on sex differences in late outcomes.

Methods: We reviewed a clinical database of consecutive patients who underwent isolated coronary artery bypass graft surgery (CABG) at FuWai Hospital from 1999 to 2005.
