Abstract

Background: Renal function significantly impacts morbidity and mortality after a percutaneous coronary intervention. Platelet glycoprotein (GP) IIb/IIIa inhibitors reduce ischemic complications during percutaneous coronary intervention; little is known of whether their safety and efficacy are influenced by renal function. In particular, whether outcome differences exist between agents that are renally excreted (tirofiban) or not (abciximab) in patients with mild renal impairment is not known. Methods: The TARGET trial randomized 4623 patients to tirofiban or abciximab. In this analysis, patients were grouped in creatinine clearance quartiles (<70, 70-90, 90-114, >114 mL/min) and analyzed for efficacy and bleeding risk. Univariate and multivariate analyses were performed to identify interactions between GP IIb/IIIa inhibitor used and creatinine clearance with respect to ischemic outcomes and bleeding. Results: Using unadjusted logistic regression tests for trend, 30-day death/myocardial infarction/urgent target vessel revascularization was greater in patients with lower creatinine clearances (7.3%, 8.5%, 5.1%, and 5.8%, P = .005), as were both major and minor bleeding. There was no interaction between assigned GP IIb/IIIa inhibitor, creatinine clearance and ischemic outcome, major bleeding or minor bleeding. Conclusions: Both ischemic and bleeding complications are highest in the lowest creatinine clearance quartile of patients treated with GP IIb/IIIa inhibitors. Although tirofiban is renally cleared and abciximab is not, there was no interaction between these GP IIb/IIIa inhibitors and creatinine clearance regarding ischemic or bleeding events.
