Comparative Study
Off-pump techniques disproportionately benefit women and narrow the gender disparity in outcomes after coronary artery bypass surgery.
Women experience greater morbidity and mortality than men after conventional coronary artery bypass grafting (CABG) on cardiopulmonary bypass (CPB). The objective of this study was to determine whether off-pump CABG (OPCAB) alters this gender-based disparity. ⋯ OPCAB is associated with fewer major adverse cardiac events and benefits women disproportionately, thereby narrowing the gender disparity in clinical outcomes after CABG.

Off-pump coronary artery bypass graft surgery (OPCAB) has been performed for many years, but its use is increasing in frequency, and it remains an open question whether OPCAB is associated with better outcomes than on-pump coronary artery bypass graft (CABG) surgery. ⋯ OPCAB is associated with lower in-hospital mortality and complication rates than on-pump CABG, but long-term outcomes are comparable, except for freedom from revascularization, which favors on-pump CABG.
