Overview

abstract

  • BACKGROUND: Argatroban, a direct thrombin inhibitor, blocks clot-bound thrombin more effectively than does heparin. This multicenter, prospective pilot study evaluated the efficacy and safety of argatroban in combination with glycoprotein IIb/IIIa inhibition in patients undergoing percutaneous coronary intervention. METHODS: Patients (N = 152) received argatroban as a 250- or 300-mug/kg bolus, followed by a 15-mug/kg/min infusion during percutaneous coronary intervention. An additional 150-mug/kg bolus was administered if activated clotting times 5-15 min after initiating argatroban were <275 s. Abciximab (N = 150) or double-bolus eptifibatide (N = 2) was administered simultaneously. RESULTS: Median activated clotting times at the beginning and end of the procedure were approximately 300 s. The primary efficacy endpoint-a composite of death, myocardial infarction, or urgent revascularization at 30 days-occurred in 4 (2.6%) patients (no death, 4 myocardial infarctions, and 2 revascularizations). Two (1.3%) patients had major bleeding by the Thrombolysis in Myocardial Infarction criteria (1 retroperitoneal, 1 groin hematoma). CONCLUSIONS: Argatroban in combination with glycoprotein IIb/IIIa inhibition appears to provide adequate anticoagulation and be well tolerated with an acceptable bleeding risk for patients undergoing percutaneous coronary intervention. Additional studies are warranted.
