Abstract

OBJECTIVES:

The purpose of this study was to examine the in-hospital outcome and influence of glycoprotein (GP) IIb/IIIa antagonists on patients with acute coronary syndromes (ACS) across a range of renal function.

BACKGROUND:

Recent studies demonstrate increasing cardiovascular risk with progressive renal dysfunction. Previous studies investigating GP IIb/IIIa antagonist use have excluded patients with renal dysfunction.

METHODS:

Patients presenting with ACS between January 1999 and May 2000 were identified, and data on demographics, in-hospital management, and clinical events were collected using standardized definitions. Patients were stratified according to renal function assessed by calculated creatinine clearance (CrCl) at presentation. Primary outcome measures included in-hospital mortality and major bleeding events.

RESULTS:

Renal insufficiency was present in 312 of 889 patients. There were 40 in-hospital deaths. In non-dialysis-dependent patients, as CrCl worsened, there was a decline in utilization of routine diagnostics and therapeutics, an increase in in-hospital mortality (p = 0.002), and an increase in major bleeding (p = 0.03). Although the use of GP IIb/IIIa antagonists was associated with an increase in major bleeding (p < 0.001), there was a protective effect on in-hospital mortality (p = 0.04) after controlling for CrCl.

CONCLUSIONS:

Renal dysfunction is present in a substantial proportion of patients with ACS and is associated with increased in-hospital death. Although GP IIb/IIIa antagonist use in patients with ACS and renal insufficiency resulted in increased bleeding events, its administration was associated with a decreased risk of in-hospital mortality. These preliminary findings need to be confirmed in future randomized clinical trials.
