Abstract:
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). Methods: A total of 1 608 patients underwent CABG in Tianjin Chest from March 2014 to December 2017 were screened. 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. 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). 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. Kaplan-Meier survival curve was used to compare the cumulative event-free survival rates. The risk factors for the MACE in the patients with late SVGD and treated by interventional therapy were analyzed by Cox regression analysis. Results: A total of 165 patients were included for analysis, including 98 males(59.4%). The age was (64.2±7.1) years old. The follow-up time was 12 (8, 12) months. In the grafts group, operation success rate was 90.57%(48/53), and 3 cases(5.66%) suffered from serious complications after interventional treatment, 2 cases(3.77%) died. For native group the operation success rate was 88.39%(99/112), and 7(6.25%) cases suffered from serious complications after interventional treatment, and no deaths. The operation success rate and the incidences of serious complications after interventional treatment in two groups had no statistically significant difference(both P>0.05). The mortality in hospital of native group was lower than that in grafts group(P<0.05). Within 12 months after discharge, there was no statistically significant difference in incidence of MACE of two groups (11.32%(6/53) vs. 10.71%(12/112), P>0.05). Survival analysis showed that the cumulative event-free survival rates in two groups were 73.58% (39/53) and 66.13%(74/112), and there was no statistically significant difference (P>0.05). Cox regression analysis showed acute coronary syndrome (HR=41.203, 95%CI 4.859-349.361, P<0.01), and peripheral vascular diseases (HR=2.808, 95%CI 1.067-7.393, P<0.05) were the risk factors of the MACE for the patients treated by interventional therapy with late SVGD. Conclusion: For the patients with late SVGD after CABG, the success rate of intervention with vein grafts and own coronary vessels are both high with satisfactory safety.The in-hospital mortality of interventional therapy in own coronary vessels is lower than in graft vessel. Patients with acute coronary syndrome and peripheral vascular disease have a poor prognosis.
