Long-term clinical outcomes in diabetics after coronary artery bypass surgery and coronary stenting.

Background : Diabetes is a major risk factor for restenosis after percuataneous coronary intervention (PCI) and coronary artery bypass surgery (CABG) has been considered desirable in diabetics with multivessel disease. However, recent developments in devices and techniques of PCI have led to speculation about advantages of CABG in diabetic patients. We sought to compare long-term clinical outcomes of coronary stenting and those of CABG in diabetics with coronary artery disease. Methods : Among diabetics who underwent revascularization therapy in Chonnam National University Hospital between Mar 1998 and Feb 1999, 122 patients (Group I, 84 males, 608 years) who had stent implanted, and 38 patients (Group II, 24 males, 608 years) who had bypass surgery were selected and their short- and long-term clinical were compared. Results : As for clinical diagnosis and risk factors there were no differences between the two groups. In ACC/AHA types Group II had more multiple and complex vessel disease than Group I(p6.7 months the incidence of target lesion revascularization was significantly higher in Group I (18.9% versus 5.7%, p
