Mortality at 1 year with combination platelet glycoprotein IIb/IIIa inhibition and reduced-dose fibrinolytic therapy vs conventional fibrinolytic therapy for acute myocardial infarction: GUSTO V randomized trial.


Journal Article

CONTEXT: Among patients with acute myocardial infarction, combination reperfusion therapy with a platelet glycoprotein IIb/IIIa receptor inhibitor (abciximab) and a half dose of a plasminogen activator (reteplase) did not significantly reduce mortality at 30 days compared with a full dose of reteplase. Rates of nonfatal ischemic complications were significantly diminished. OBJECTIVE: To determine if the beneficial effects of abciximab and reteplase (combination therapy) on early nonfatal complications would translate into a reduction in the risk of death by 1 year. DESIGN, SETTING, AND PATIENTS: One-year follow-up of a randomized controlled trial (Global Use of Strategies To Open Coronary Arteries [GUSTO] V). Of 16 588 patients who had been treated in 820 community and referral hospitals in 20 countries between July 1999 and February 2001, mortality data were available for 16 453 (99.2%). INTERVENTION: Patients were randomly assigned to receive (intravenously) a standard dose of reteplase (two 10-U boluses, 30 minutes apart) or the combination of a standard dose of abciximab (0.25 mg/kg bolus, 0.125 microg/kg per minute infusion [maximum 10 micro g/min for 12 hours]) and a half dose of reteplase (two 5-U boluses, 30 minutes apart). MAIN OUTCOME MEASURE: One-year all-cause mortality rates. RESULTS: All-cause mortality at 1 year occurred in 692 (8.38%) of 8260 patients in the reteplase group and 698 (8.38%) of the 8328 patients in the combination therapy group (hazard ratio [HR], 1.00; 95% confidence interval [CI], 0.90-1.11; P>.99). Reinfarction within the first 7 days occurred in 3.5% of patients in the reteplase group and 2.3% of patients in the combination therapy group, and was significantly associated with 1-year mortality (22.6% in patients with reinfarction vs 8.0% in patients without reinfarction; HR, 3.08; 95% CI, 2.53-3.75; P<.001). However, treatment assignment did not significantly influence time of mortality regardless of reinfarction status. CONCLUSION: Combination therapy (abciximab and reteplase) did not reduce mortality over 1 year compared with fibrinolytic therapy with reteplase alone.
