Abstract: Objective To explore coronary angiographic characteristics in patients with symptomatic recurrence after coronary artery bypass grafting (CABG). Methods We performed a retrospective study of 997 patients with symptomatic recurrence after CABG in Beijing Anzhen Hospital from 2010 to 2020. There were 762 males and 235 females, with an average age of 62.41±8.70 years. Results There was a high prevalence of risk factors like hypertension, diabetes and a history of smoking. Diseased arterial grafts accounted for 27.44% while saphenous vein graft 54.40%; 240 (24.07%) patients had all patent grafts. The main lesion characteristics of diseased grafts were chronic total occlusion lesions (79.57%). Most patients had more diseased native vessels after CABG than before. The type C coronary artery disease in native vessels relevant to ischemic area occurred in 674 (67.60%) patients; 525 (52.66%) patients with recurrent symptom after CABG had both diseased grafts and diseased native vessels. Conclusion Graft status in patients with symptomatic recurrence after CABG is worse than we expected. The majority have newly developed lesions both in grafts and native vessels. Native vascular lesions will continue to progress after CABG.
