Abstract

Objective: The Japanese Off-Pump Coronary Revascularization Investigation (JOCRI) study reported a non-significant difference in early outcomes and graft patency between off-pump coronary artery bypass grafting and on-pump coronary artery bypass grafting in 2005. The JOCRIED study aimed to review the long-term outcomes of the JOCRI study participants. Method and results: The JOCRIED study enrolled 123 of the JOCRI study participants completing the clinical follow-up between August 2018 and August 2020; 61 patients in the off-pump group and 62 patients in the on-pump group. The follow-up period was 13.8 ± 2.8 years. The groups were compared regarding mortality, the incidence of major adverse cardiac and cerebrovascular events and repeat revascularisation. The 15-year cumulative survival rate (off-pump vs on-pump, respectively; 77.7% vs 75.3%; p = 0.85), major adverse events-free survival rate (62.5% vs 55.6%; p = 0.27) and repeat revascularisation-free rate (84.8% vs 78.0%; p = 0.16) were not significantly different between the two groups. Revascularisation was the most common major adverse events in the JOCRIED participants. Although percutaneous coronary intervention was performed in 8 patients (13%) in the off-pump group and in 14 patients (23%) in the on-pump group (p = 0.23), no patients underwent redo coronary artery bypass grafting. Conclusions: Off-pump coronary artery bypass grafting provides comparable 15-year outcomes to on-pump coronary artery bypass grafting.
