Objective: This study determined hazard factors and long-term survival rate of total arterial coronary artery bypass graft surgery over 20 years in an extensively large, population-based cohort. Methods: A total of 2979 patients who underwent isolated CABG from April 1999 to March 2020 were studied in 4 groups- Group-A (bilateral internal mammary artery [+ or -] radial artery), Group-B (single internal mammary artery + radial artery [+ or -] saphenous vein), Group-C (single internal mammary artery [+ or -] saphenous vein; no radial artery), and Group-D (radial artery [+ or -] saphenous vein; no internal mammary artery). The study endpoints analysed the correlation between the number and types of grafts with the survival time following isolated CABG surgery. Results: The total arterial revascularization (Group A) group had an admirable mean long-term survival of ~19 years, compared to 18.6 years (Group B), 15.86 years (Group C), and 10.99 years (Group D). A Kaplan-Meier curve demonstrated confidence interval (CI) for study groups- (95% CI 18.33-19.94,95% CI 18.14-19.06,95% CI 15.40- 16.32), and (95% CI 9.61-12.38) in Group A, B, C, D respectively. In the Holm-Sidak method analysis, significant associations existed between the number of arterial grafts and the long-term outcome.

Introduction Coronary artery bypass graft (CABG) surgery is the preferred revascularisation strategy for multivessel coronary artery disease (CAD). (1,2) However, there is significant evidence in the literature that the type [...]
