Objective To compare the superiority of total arterial revascularization in patients with coronary artery disease (CAD) complicated with left ventricular dysfunction. Methods This retrospective study included the patients who were diagnosed with CAD and the left ventricular ejection fraction (LVEF) of ≤40% and underwent coronary artery bypass grafting (CABG) at our hospital from January 2016 to July 2019. The patients were divided into two groups according to the different types of bypass vessels: a total arterial revascularization group (TAR group) and a conventional group (a CON group). The clinical data were compared between the two groups to explore the incidence of important complications and evaluate the safety of total arterial revascularization and its protective effect on cardiac function. Results  Finally 75 patients were enrolled including 52 males and 23 females with a mean age of 61.58±7.93 years. There were 35 patients in the TAR group and 40 patients in the CON group. The operation time and the drainage volume at 24 hours after operation in the TAR group were longer or more than those in the CON group (P<0.05), but there was no statistical difference in hospital stay, postoperative complications (such as respiratory failure, mediastinal infection, renal failure), intra-aortic balloon pump or extracorporeal membrane oxygenation use rate (P>0.05). After 2 years of follow-up, compared with the CON group, the cardiac function of the TAR group was significantly improved, the LVEF was higher, the left ventricular end diastolic diameter was reduced, and the graft stenosis rate was lower (all P<0.05). Conclusion  Total arterial revascularization is a safe and feasible surgical method, which is helpful to improve the cardiac function and improve the quality of life.
