Diagnosis and management of significant LMCAD continues to be a source of clinical apprehension and uncertainty. Left main coronary artery disease (LMCAD) portends higher prognostic risk as a result of the large myocardial territory at risk, ranging from 75% to 100%, depending on the dominance of the left coronary circulation.

The risk factors for the MACE in the patients with late SVGD and treated by interventional therapy were analyzed by Cox regression analysis. Kaplan-Meier survival curve was used to compare the cumulative event-free survival rates. The operation success rate, mortality and incidence of serious complications after interventional treatment in two groups at the time of hospitalization were compared.And the incidence of major adverse cardiovascular events(MACE) in two groups at one year after discharge were also compared. According to the results of angiography and surgeon's clinical experiences, the patients received interventional treatment to vein grafts(grafts group, n=53) or native coronary vessels(native group, n=112). During the follow-up period, 165 hospitalized patients with recurrence of angina pectoris within one year after CABG, who had at least one narrow vein graft(≥50%) confirmed by the coronary angiography were enrolled. Methods: A total of 1 608 patients underwent CABG in Tianjin Chest from March 2014 to December 2017 were screened. Objective: To compare clinical efficacy of interventional treatment with graft vessel and native coronary artery for patients with late saphenous vein grafts disease(SVGD) after coronary artery bypass grafting (CABG).
