Long-term outcome of total arterial myocardial revascularization versus conventional coronary artery by-pass in diabetic and non diabetic patients: A propensity-match analysis
2019
Abstract Objective Despite the improved survival in patients with multi-vessel coronary disease compared to conventional myocardial revascularization associated with the use of multiple arterial grafting for myocardial revascularization, it has been adopted in the minority of centers. We sought to evaluate the long-term outcome of patients with and without diabetes undergoing total arterial versus conventional myocardial revascularization. Methods Among 1000 consecutive patients undergoing CABG, we performed a propensity-match analysis to compare patients with multi-vessel disease receiving total arterial (G1 = 618 pts) versus conventional myocardial revascularization (LIMA-LAD plus vein grafts,G2 = 382 pts). The primary end-point was survival free from all-cause and cardiac-related mortality, while the secondary end-point was the occurrence of major cardiac and cerebrovascular accidents. Results Hospital mortality was similar (G1: 0 pts. vs G2: 1 pts., 0.3%, p = .91). At a median follow-up of 101 months (range 11–185 months), total arterial grafting was associated with significantly improved survival free from overall (G1 = 76.5 ± 3.0% vs G2 = 66.0 ± 3.1%; p .001; diabetics:G1 = 77 ± 6 vs G2 = 53 ± 5.8; p Conclusions Long term survival following total arterial CABG is remarkably improved compared to conventional grafting with vein grafts especially in diabetic patients.
