  8. Primary PCIvsFibrinolysisTime dependantbenefit • Meta-analysis of 23 trials of 1ry PCI vs fibrinolysis relating 4-6 week death difference to PCI-related time delay. Mortality benefit of Primary PCI may be lost if door-to-balloon time is delayed by >60 min compared with door-to-needle time Am J Cardiol 2003; 92:824

  12. Untimely reperfusion (after hospital presentation): • Fibrinolytic therapy > 30 min (54%) • Primary PCI > 90 min (68%) JAMA 2010; 303(21):2148-2155

  13. Choice of Reperfusion Therapy Primary PCIvsFLT Patient Oriented Therapyfor STE-MI Regardless of the mode of the therapy, primary goal should be to “minimize total ischemic time”; time from onset of symptoms to initiation of reperfusion therapy “TIMELY REPERFUSION”

  14. Patient Oriented Therapyfor STE-MI Fibrinolytic Therapy – Secondary PCI “Triage and Transfer for PCI”

  15. STE-AMI :“Triage and Transfer for PCI”

  16. STE-AMI :Pharmacoinvasivestrategy The high risk patients who receive FLT as a primary reperfusion therapy at a non-PCI hospital can be transfered to a PCI-hospital inorder to perform PCI as a part of “pharmacoinvasive strategy”

  17. CARESS-IN-AMI primary outcome :composite of all cause mortality, reinfarction, & refractory MI within 30 days Non-PCI hospital: half-dose lytic (reteplase) + abciximab+ UFH 10.7% • High risk STEMI (<12 hours) • With one or more high-risk features: • extensive ST-segment elevation • new-onset left bundle branch block • previous MI • Killip class >2, or • left ventricular ejection fraction <35% for inferior MIs; • Anterior MI alone with 2 mm or more ST-elevation in 2 or more leads 4.4% HR=0.40 (0.21-0.76) Di Mario et al.

  28. Clopidogrel Under Fire: Is Prasugrel in Primary PCI or Recent MI Superior? Insights From TRITON-TIMI-38 Gilles Montalescot, Stephen D. Wiviott, Eugene Braunwald, Sabina A. Murphy, C. Michael Gibson, Carolyn H. McCabe and Elliott M. Antman, for the TRITON–TIMI 38 Investigators All ACS/PCI patients N=13608 UA/NSTEMI patients N=10074 STEMI patients N=3534 Primary PCI N=2438 (69%) Secondary PCI N=1094 (31%)* Clopidogrel N=1235 Prasugrel N=1203 Clopidogrel N=530 Prasugrel N=564 Montalescot et al.

  31. Prasugrel was superior to standard dose clopidogrel to prevent ischaemic events Prasugrel did not have more bleeding events compared to those who were treated with clopidogrel, and this was equally true for: Primary PCI Secondary PCI Major bleeding Minor bleeding Conclusions In STEMI patients undergoing PCI TRITON-TIMI 38 :STEMI TRITON-TIMI 38 :STEMI These data make prasugrel an especially attractive alternative to clopidogrel in PCI for STEMI Montalescot et al ESC 2008

  32. STE-AMI : AdjunctiveAntiplateletTherapy (2009) • Choice of Thienopyridine for PCI in STEMI: • Prasugrel is not not endorsed explicitly over Clopidogrel • - Benefit is predominantly by reduction in non-fatal MI • (Death & nonfatal stroke similar + increased hemorraghic risk) • - Loading dose of Cloidogrel (300 mg – TRINITON TIMI 38) was • lower tha currently recommended doses

  36. PLATOSTEMI Hierarchical testing of major efficacy endpoints

  37. PLATOSTEMI Conclusions • Reversible, more intense P2Y12 receptor inhibition for one year with ticagrelorin comparison with clopidogrel in patients with STEMI intended for reperfusion with primary PCI provides • Reduction in composite of CV death, MI or stroke • Reduction in MI and stent thrombosis • Reduction in total mortality • No increase in the risk of major bleeding • The mortality reduction is afforded on top of modern care Ticagrelor may become a new standard of care for the management of patients with STEMI intended for primary PCI

  43. STE-AMI : Adjunctive Antiplatelet Therapy (2010)

  44. STE-AMI : Adjunctive Antiplatelet Therapy (2011) • Clopidogrel: Class I-B (PCI) 600 mg loading dose now recommended No spesific recommendation for STE-MI • GP IIb/IIIa inhibitor : Class II-A May be most appropriate with large anterior MI and/or large thrombus burden IC abciximab (Class IIb-B) Precatheterization lab. GPI administration (Class III-no benefit) • Antithrombin agents (UFH-Bivaluridine-Enoxaparine): No spesific recommendation for STE-MI
