Abstract:
Objective:To assess the clinical characteristics and grafts status by coronary angiography(CAG) in symptomatic patients with prior coronary artery bypass graft(CABG).Methods:A retrospective descriptive study of symptomatic patients with prior CABG who underwent CAG was performed, 1 136 patients were included and analyzed. The mean age was(62.5±8.7) years, 76.4% were male. There was a high prevalence of risk factors like hypertension(75.0%), dyslipidemia(48.2%), diabetes(46.1%) and smoking history(62.8%).Results:The mean duration after CABG was (4.65±3.39) years. 94.5% of patients had chest pain. 12.9% of patients had all diseased grafts and 28.7% had all patent grafts. The proportion of diseased SVG was higher than that of diseased arterial grafts. The proportion of diseased grafts anastomosed to RCA territory was higher than that of grafts anastomosed to LCX territory or LAD territory. 52.5% of patients received percutaneous coronary intervention(PCI) revascularization, and 88.3% of PCI was performed in native vessels.Conclusion:The most common symptom recurring to patients with prior CABG was chest pain. Graft status in symptomatic patients with prior CABG was worse than we expected. Patients received repeated revascularization mostly by PCI and PCI was mainly performed in native vessels.
