Purpose
In the Bavarian Reperfusion Alternatives Evaluation (BRAVE)-3 study upstream administration of abciximab additional to 600 mg clopidogrel loading did not reduce the infarct size in patients with acute ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary interventions. The aim of this study was to investigate 1-year clinical outcomes in the BRAVE-3 study patients.
Methods
A total of 800 patients with acute STEMI within 24 h from symptom onset, all treated with 600 mg of clopidogrel were randomized in a double-blind fashion to receive either abciximab (n = 401) or placebo (n = 399) in the intensive care unit before being sent to the catheterization laboratory.
Results
The main outcome of interest of the present study, the composite of death, recurrent myocardial infarction, stroke or revascularization of the infarct-related artery (IRA) at 1 year, was 23.0% (92 patients) in the abciximab versus 25.7% (102 patients) in the placebo group [relative risk (RR) = 0.90, 95% confidence interval (CI) 0.67–1.20; P = 0.46]. The combined incidence of death, recurrent myocardial infarction or stroke was 9.3% in the abciximab group versus 6.0% in the placebo group (RR = 1.55, 95% CI 0.93–2.58; P = 0.09). There was a significant reduction of the IRA revascularization with abciximab compared to placebo (16.3 vs. 22.3%, RR = 0.71, 95% CI 0.52–0.98; P = 0.04).
Conclusion
In patients with STEMI, all receiving 600 mg clopidogrel, abciximab did not improve overall clinical outcomes at 1 year after primary coronary stenting.
