Titel:
Coronary revascularization in patients with renal insufficiency: restenosis rate and cardiovascular outcomes. 
Abstract:
BACKGROUND: Several interventional trials have shown a lower success rate for coronary angioplasty and lower long-term event-free survival in patients with renal insufficiency, and data are conflicting about restenosis after coronary angioplasty. METHODS: This study included 4,131 consecutive patients with coronary artery disease treated with coronary angioplasty (23%) or stenting (77%). Renal insufficiency is defined as a creatinine clearance (CrCl) less than 60 mL/min (<1.0 mL/s). Of 4,131 patients, 1,412 patients (34.2%) had renal insufficiency and 2,719 patients (65.8%) did not have renal insufficiency. The primary end point of the study is clinical restenosis, defined as the need for target-lesion revascularization. RESULTS: There was no difference in clinical restenosis rates between groups after 1 year (18.8% versus 18.4%; P = 0.75). The incidence of angiographic restenosis at the 6-month angiography was 32.7% in the group with renal insufficiency and 29.7% in the group without renal insufficiency ( P = 0.10). The composite end point of death and myocardial infarction was observed more frequently in patients with than without renal insufficiency (8.3% versus 3.2%; P< 0.001). Renal insufficiency was not independently associated with clinical restenosis (for 10-mL/min [0.167-mL/s]) decrease in CrCl, adjusted odds ratio, 1.03; 95% confidence interval [CI], 0.98 to 1.08; P = 0.198), but remained as an independent predictor for death or myocardial infarction (for 10-mL/min [0.167-mL/s] decrease in CrCl, hazard ratio, 1.29; 95% CI, 1.18 to 1.42; P< 0.001). CONCLUSION: Patients with renal insufficiency do not show an increased incidence of restenosis after coronary revascularization.
