Incomplete Revascularization During OPCAB Surgery is Associated With Reduced Mid-Term Event-Free Survival

Compared with off-pump coronary artery bypass surgery patients with complete revascularizations, those with IRs have reduced survival, but only in the first 4 to 6 months after surgery. Patients' preoperative condition, rather than IR itself, may explain these findings because IRs should have mid-term as well as early effects.
