PURPOSE: We sought to examine if percutaneous intervention (PCI) prior to coronary artery bypass surgery (CABG) adversely affect perioperative and long-term outcomes following surgical revascularization.
METHODS: Patients were 3,282 patients who underwent first-time, isolated CABG between 2001 and 2004. Survival at 1-year and major postoperative complications for 427 patients with prior PCI (Group 2) was compared to 2,855 patients with no prior PCI (Group 1).
RESULTS: Operative death was 0.8% in Group 1 and 0.9% in Group 2 (Adjusted OR: 1.12; 95% CI: 0.39 –3.23). A trend for higher incidence of post-operative complications was observed in Group 2 pts. Average follow-up was 5.7 ± 1.6 years. No difference in 1-year mortality between groups (Group 1: 5.6% vs. 3.8%, p<0.115) or long-term mortality between groups (Group 1: 7.6% vs. 6.2%, p<0.264).
CONCLUSION: No negative impact of previous PCI in patients undergoing subsequent CABG was identified either for perioperative complications or long term-survival.
CLINICAL IMPLICATIONS: PCI is associated with an increased need for repeat revascularization compared to CABG, but remains a more frequently utilized strategy for initial revascularization. Clinicians and patients can be reassured that should a CABG be necessary for subsequent repeat revascularization, long-term survival will not be negatively affected by initial revascularization with PCI.
