Background Abciximab reduces major adverse cardiac events in patients with ST-elevation myocardial infarction undergoing primary percutaneous coronary intervention (PCI). Intracoronary bolus application of abciximab results in high local drug concentrations and may be more effective than standard intravenous bolus application for reduction of infarct size, no-reflow and improvement in perfusion. Methods Patients undergoing primary PCI were randomized to either intracoronary (n=77) or intravenous (n=77) bolus administration of abciximab with subsequent 12 hour intravenous infusion. Primary endpoint was infarct size and extent of microvascular obstruction assessed by delayed enhancement magnetic resonance. Secondary endpoints were ST-resolution at 90 minutes, Thrombolysis in Myocardial Infarction (TIMI)-flow and perfusion grade post PCI, and the occurrence of major adverse cardiac events within 30 days. Results The primary endpoint infarct size could be reduced by absolute 7% (17.7% i.c. versus 24.7% i.v., p=0.005). Similarly, the extent of microvascular obstruction was significantly smaller in i.c. patients in comparison to i.v. patients (p=0.02). Myocardial perfusion measured as early ST-segment resolution was significantly improved in i.c. patients with an absolute ST-resolution of 76±23% versus 64±31% (p=0.009). The TIMI flow after PCI was not different between treatment groups (p=0.51), but there was a trend towards an improved perfusion grade (p=0.12). There was a trend towards a higher major adverse cardiac event rate after intravenous versus intracoronary abciximab application (15.6% versus 5.2%, p=0.06; relative risk 3.00; 95% confidence intervals 0.94 –10.80). Conclusions: Intracoronary bolus administration of abciximab is superior to standard intravenous treatment with respect to infarct size, extent of microvascular obstruction, and perfusion in primary PCI. An adequately powered trial for major adverse cardiac event reduction is warranted.

Aims. We investigate the effect of glycoprotein IIb/IIIa (GP IIb/IIIa) inhibitors on long-term outcomes following percutaneous coronary intervention (PCI) after non-ST elevation myocardial infarction (NSTEMI). Meta-analyses indicate that these agents are associated with improved short-term outcomes. However, many trials were undertaken before the routine use of P2Y12inhibitors. Recent studies yield conflicting results and registry data have suggested that GP IIb/IIIa inhibitors may cause more bleeding than what trials indicate.Methods and Results. This retrospective observational study involves 3047 patients receiving dual-antiplatelet therapy who underwent PCI for NSTEMI. Primary outcome was all-cause mortality. Major adverse cardiac events (MACE) were a secondary outcome. Mean follow-up was 4.6 years. Patients treated with GP IIb/IIIa inhibitors were younger with fewer comorbidities. Although the unadjusted Kaplan-Meier analysis suggested that GP IIb/IIIa inhibitor use was associated with improved outcomes, multivariate analysis (including propensity scoring) showed no benefit for either survival (P=0.136) or MACE (P=0.614). GP IIb/IIIa inhibitor use was associated with an increased risk of major bleeding (P=0.021).Conclusion. Although GP IIb/IIIa inhibitor use appeared to improve outcomes after PCI for NSTEMI, patients who received GP IIb/IIIa inhibitors tended to be at lower risk. After multivariate adjustment we observed no improvement in MACE or survival and an increased risk of major bleeding.

Background: Bivalirudin decreased bleeding and improved mortality in ST-elevation myocardial infarction (STEMI) patients undergoing percutaneous coronary intervention (PCI) in the HORIZON trial. Currently there is limited data regarding the benefits of bivalirudin in unselected STEMI patients in real-world clinical practice. Methods: We reviewed consecutive STEMI patients at a large regional STEMI referral center from June 2009 to December 2011. All patients received aspirin and P2Y12 inhibitors. In-hospital complications, length of stay (LOS), total variable costs, 1-year cardiovascular readmissions, major adverse cardiac events (MACE) and mortality were compared for: bivalirudin alone, heparin alone and either medication with IIb/IIIa inhibitors. Results: Among 759 STEMI PCI cases, 208 (27.4%) received bivalirudin, 216 (28.5%) heparin and 335 (44.1%) IIb/IIIa, including only 48 cases with bivalirudin. Bivalirudin alone had significantly lower in-hospital complications, bleeding events, mortality and 1-year MACE and mortality (p<0.05 for all) (Figure). There were no significant differences in LOS (median 2.6 vs. 2.8 vs. 2.9 days; p=0.065), total variable costs (median $9,303 vs. $9,242 vs. $9,860; p=0.15) or readmissions within 1 year. Conclusions: In an unselected population of STEMI patients, those treated with bivalirudin had lower in-hospital complications and lower 1-year MACE and mortality rates compared to patients receiving heparin or IIb/IIIa inhibitors. These results provide further support for bivalirudin use in STEMI patients.

This article reviews optimum therapies for the management of ST-elevation myocardial infarction (STEMI) with primary percutaneous coronary intervention (PCI). Optimum anti-thrombotic therapy includes aspirin, bivalirudin and the new anti-platelet agents prasugrel or ticagrelor. Stent thrombosis (ST) has been a major concern but can be reduced by achieving optimal stent deployment, use of prasugrel or ticagrelor, selective use of drug-eluting stents (DES) and use of new generation DES. Large thrombus burden is often associated poor outcomes. Patients with moderate to large thrombus should be managed with aspiration thrombectomy and patients with giant thrombus should be treated with glycoprotein IIb/IIIa inhibitors and may require rheolytic thrombectomy. The great majority of STEMI patients presenting at non-PCI hospitals can best be managed with transfer for primary PCI even with substantial delays. A small group of patients who present very early, who are at high clinical risk and have long delays to PCI, may best be treated with a pharmaco-invasive strategy.
