What are the reasons of variation in lethality?
• Different patient risk profile ?– Shock – age - ischemic time– Correction with TIMI risk score
• Different reperfusion modalities? trombolysis vs PCI vs no reperfusion

Optimalisation of reperfusion therapy (ESC report)
1. Reperfusion therapy (thrombolysis – PCI) in STEMI favourably influences short and long term patient outcome
2. Up to 40% of all STEMI patients do not receive re perfusion therapy in Europe (ESC-ACS registry 2001). (Belgian da ta?)
3. Optimalisation of reperfusion therapy can be achi eved by organising conference meetings, providing guidelines and setting up registries.
4. Importance of networks of reperfusion (including transport organisation) to limit time delay between onset of s ymptoms and initiation of reperfusion therapy.

Time issue and reperfusion strategy
If PCI-related time delay >60 min,
the benefit of PCI over thrombolyis vanishes
