ObjectiveThe objective of this retrospective analysis of high-risk patients treated with bivalirudin during primary percutaneous coronary intervention (PCI) for ST-segment elevation myocardial infarction (STEMI) was to evaluate the safety and feasibility of direct thrombin inhibitor (DTI) without concomitant glycoprotein (GP) IIb/IIIa inhibition.BackgroundReperfusion by PCI is the treatment of choice for patients with STEMI. In patients with stable or unstable angina without ST-segment elevation undergoing PCI, bivalirudin was at least as effective as heparin plus GPIIb/IIIa inhibitors in reducing ischemic events and more effective in preventing bleeding. There are no published studies detailing the use of bivalirudin in patients with STEMI.MethodsFrom 09/02 to 05/03 at the Heart Care Centers of Illinois, Blue Island, Illinois. Ninety-one consecutive patients with STEMI underwent PCI with or without stent placement. Bivalirudin was administered as a bolus dose (0.75 mg/kg) followed by infusion (1.75 mg/kg/hr) for the duration of the procedure. Outcomes were recorded over a 30-day follow-up period.ResultsPatients (n = 91) had several high-risk characteristics (40% female, 30% diabetes mellitus, 21% previous MI and 18% cardiogenic shock). PCI procedures utilized balloons, stents, or a combination of both. Intraaortic balloon pumps were used for 41% and closure devices for 24% of patients.ConclusionsThis evaluation demonstrates excellent TIMI flow without the addition of GPIIb/IIIa inhibitors. The low mortality and complication rates suggest anticoagulation with bivalirudin in patients with STEMI undergoing PCI is feasible and warrants further study in larger controlled trials to evaluate the effectiveness of bivalirudin in this patient population.
