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.

Abstract Background Primary percutaneous coronary intervention (PCI) is the cornerstone of management for ST-elevation myocardial infarction (STEMI). However, large intracoronary thrombus burden complicates up to 70% of STEMI cases. Adjunct therapies described to address intracoronary thrombus include manual and mechanical thrombectomy, use of distal protection device and intracoronary anti-thrombotic therapies. Case summary This series demonstrates the use of intracoronary thrombolysis in the setting of large coronary thrombus, bifurcation lesions with vessel size mismatch, diffuse thrombosis without underlying plaque rupture, and improving coronary flow to allow vessel wiring and proceeding to definitive revascularization. Discussion Larger intracoronary thrombus burden correlates with greater infarct size, distal embolization, and the associated no-reflow phenomena, and propagates stent thrombosis, with subsequent increase in mortality and major adverse cardiac events. Intracoronary thrombolysis may provide useful adjunct therapy in highly selected STEMI cases to reduce intracoronary thrombus and facilitate revascularization.

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.

Reperfusion Strategy

On the example of the clinical case of newly diagnosed ST-elevation myocardial infarction combination of different reperfution strategies and their benefit was discussed. Recommendations on lifestyle modification and medicament treatment tactics are described. From one hand, in spite of side-effects of treatment as an increased risk of stroke and hemorrhagic stroke, prehospital FL is associated with a decreased risk of cardiogenic shock and its effectiveness depends on the time from symptom onset to reperfusion. From other hand, despite the fact that PPCI is the recommended default reperfusion strategy, its effectiveness depends also on time limits and absence of the majority of PPCI-facilated hospitals worldwide. Combination of prehospital single-bolus FL following after 3–24h early routine angiography and PCIcan improve post-STEMI survival and help to avoid hyperreactivity and thrombin-induced platelet activation after FL, which can be a key to success in effective treatment and rehabilitationafter STEMI in patients without high risk factors of potential bleeding or stroke.

Reperfusion Strategy

SummaryPrimary percutaneous coronary intervention (PPCI) is the preferred reperfusion therapy in ST-elevation myocardial infarction (STEMI), as long as it can be delivered within 90-120 minutes from patient’s first medical contact, and is the leading reperfusion strategy in most European countries. However, as PPCI cannot be offered in a timely manner to all patients, fibrinolytic therapy (FT) is the recommended choice in patients with an anticipated delay to PPCI of >90-120 minutes, presenting early after symptom onset and without contra-indications. FT should preferably be started in the pre-hospital setting. Following FT, all patients should be transferred to a PCI-center for rescue PCI or routine coronary angiography with PCI as indicated. Such a pharmaco-invasive strategy, combining FT with invasive treatment, has recently been shown to be non-inferior to PPCI in patients living in areas with long transfer delays to PCI (>60 minutes).In this overview, we will briefly present the evidence for the benefit of FT in STEMI, and discuss the role of FT in the current era of PPCI as well as the optimal treatment following pharmacologic reperfusion.

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.
