  1. Primary PCI Treatment of choice for Acute MI

  2. Benefits of primary angioplasty Incontrivertible 1993

  3. Benefits of primary angioplasty Incontrivertible 1993

  4. Myths in treating acute MI • Primary PCI is no better than thrombolysis • Primary PCI is better but not much better • Thrombolysis just needs to be given early • Thrombolysis followed by PCI is just as good • Facilitated PCI is the preferred option • Too difficult • Too expensive

  5. ESC Guidelines for the treatment of ST segment elevation

  6. Myths in treating acute MI • Primary PCI is no better than thrombolysis • Primary PCI is better but not much better • Thrombolysis just needs to be given early • Thrombolysis followed by PCI is just as good • Facilitated PCI is the preferred option • Too difficult • Too expensive

  7. Meta-analysis of 23 randomised trials comparing Primary PTCA to Thrombolysis7739 patients: 4-6 week data P<0.0001 P=0.0002 P=0.0003 P<0.0001 P=0.0004 Grines et al 2003;NEJM361:13-20

  8. True mortality benefit of Primary angioplasty 20 lives /1000 78 lives/1000 P<0.001 P<0.001

  9. True mortality benefit of Primary angioplasty 20 lives /1000 78 lives/1000 130 lives/ 1000 P<0.001 P<0.001 P<0.001

  10. Myths in treating acute MI • Primary PCI is no better than thrombolysis • Primary PCI is better but not much better • Thrombolysis just needs to be given early • Thrombolysis followed by PCI is just as good • Facilitated PCI is the preferred option • Too difficult • Too expensive

  11. Does Time Matter?Individual Patient Data-based Meta-analysis of Primary PCI versus Fibrinolysis in Acute Myocardial InfarctionRandomized Trials Eric Boersma, R John Simes, Cindy L Grines, Cynthia M Westerhout On behalf of the Primary Coronary Angioplasty versus Thrombolysis (PCAT)-2 Collaborators

  12. 30 day mortality 15 % of Patients 10 5 0 All 0 - 1 >1 - 2 >2 - 3 >3 - 6 >6 - 12 Presentation delay (h)

  13. Very Early Thrombolysis - The Golden Hour Absolute 35 day mortality reduction v treatment delay <20% patients N=50246 Fibrinolytic Therapy Trialist’s Collaborative Group, Lancet 1994 343:311 Boersma et al, Lancet 1996 348:771

  14. Myths in treating acute MI • Primary PCI is no better than thrombolysis • Primary PCI is better but not much better • Thrombolysis just needs to be given early • Thrombolysis followed by PCI is just as good • Facilitated PCI is the preferred option • Too difficult • Too expensive

  15. ASSENT 4 • Mulitcentric randomized trial comparing two strategies in acute myocardial • “Facilitated PCI” : TNK followed by immediate angiography/ angioplasty (1 to 3 hours) versus primary PTCA

  16. ASSENT 4 • 4000 pts with large MI • Study stopped after inclusion of 1667

  17. ASSENT-4: 30-day mortality results

  18. ASSENT-4: In-hospital stroke rates

  19. Comparison of outcomes in ASSENT-4 with those in other trials of TNK in MI patients

  20. Myths in treating acute MI • Primary PCI is no better than thrombolysis • Primary PCI is better but not much better • Thrombolysis just needs to be given early • Thrombolysis followed by PCI is just as good • Facilitated PCI is the preferred option • Too difficult • Too expensive

  21. Total Cumulative Costs During the First Year

  22. UK-PACES In-hospital Costs 400 consecutive patients p=0.04 p<0.001 p<0.001

  23. Myths in treating acute MI • Primary PCI is no better than thrombolysis • Primary PCI is better but not much better • Thrombolysis just needs to be given early • Thrombolysis followed by PCI is just as good • Facilitated PCI is the preferred option • Too difficult • Too expensive

  24. What have we done in the past 13 years? Benefits of primary angioplasty Incontrivertible 1993
