Name of journal: Journal of interventional cardiologyAbstract: BACKGROUND: End-stage renal disease (ESRD) is known to correlate with poor outcome in patients undergoing percutaneous coronary intervention (PCI). This study examines the impact of diabetes mellitus (DM) on the long-term outcome of patients with ESRD on chronic hemodialysis.CONCLUSION: The prognosis of patients with ESRD after PCI is dismal with a very high overall mortality rate regardless of the presence of DM. Patients with ESRD appear to be at higher risk for the need of revascularization. 2011 Wiley Periodicals, Inc.METHODS: A cohort of patients with ESRD on chronic hemodialysis, who underwent PCI with drug-eluting stents, was followed for 1 year. The clinical outcome in this population was compared retrospectively based on the presence of DM. Major adverse cardiac events (MACE) as the composite of all-cause death, Q-wave myocardial infarction and target lesion revascularization (TLR), as well as TLR as an individual outcome, were the main end points of the study.RESULTS: In the study cohort (n = 198), 48.5% had DM. Diabetic patients were more commonly female. The lesion characteristics were similar between groups except for more frequent saphenous vein graft intervention in nondiabetics. At 1-year follow-up there was no difference in the rate of MACE between diabetic and nondiabetic patients (40.4% vs. 39.3%, respectively, p = 0.89), driven primarily by a very high mortality rate (1-year overall mortality of 33.5%). After adjustment for the relevant clinical co-variables, DM was not associated with the composite end point. However, diabetic patients had a significantly higher incidence of 1-year TLR compared to nondiabetics (13.8% vs. 3.6%, respectively, p = 0.04).All authors: Kent KM, Lindsay J, Maluenda G, Pichard AD, Sardi GL, Satler LF, Suddath WO, Torguson R, Waksman R, Xue ZFiscal year: FY2012Digital Object Identifier:
