Implementation of the STEMI ESC Guidelines
ACC/AHA & ESC guidelines ESC STEMI – guidelines Primary PCI(Pre)hospital Thrombolyse Rescue PCI Onset of chestpain <12 h & transp.< 90 min to PCI rTPA if 45 – 60 min to PCI-senter No effect of thrombolyse after 45-60min: Contraindication to thrombolysis <50% ST-resolution, ongoing chestpain, arrythmias, hemodynamic unstable Patients <75 with cardiac shock early after MI (12- 36t) <75 year & cardiac shock On and off – symptoms for a longer period (EKG)
Myokardnekrose Starts 30-45min after occlusion After 90min is 40-50% necrotised After 6h the necrosis is often complete Collaterals modify Occlusion is often sub-total or fluctuating AHA Textbook of Advanced Cardiac Life Support, 1999

Reperfusion Options for STEMI Patients Step One: Assess Time and Risk. Time Since Symptom Onset Time Required for Transport to a Skilled PCI Lab Risk of STEMI Risk of Fibrinolysis
Fibrinolysis generally preferred Early presentation ( ≤ 3 hours from symptom onset and delay to invasive strategy) Invasive strategy not an option Cath lab occupied or not available Vascular access difficulties No access to skilled PCI lab Delay to invasive strategy Prolonged transport Door-to-balloon more than 90 minutes > 1 hour vs fibrinolysis (fibrin-specific agent) now Reperfusion Options for STEMI Patients Step 2: Select Reperfusion Treatment. If presentation is < 3 hours and there is no delay to an invasive strategy, there is no preference for either strategy.
Invasive strategy generally preferred Skilled PCI lab available with surgical backup Door-to-balloon < 90 minutes High Risk from STEMI Cardiogenic shock, Killip class ≥ 3 Contraindications to fibrinolysis, including increased risk of bleeding and ICH Late presentation > 3 hours from symptom onset Diagnosis of STEMI is in doubt Reperfusion Options for STEMI Patients Step 2: Select Reperfusion Treatment. If presentation is < 3 hours and there is no delay to an invasive strategy, there is no preference for either strategy.

The essence in todays PCI - ”Guidelines” (2005). STEMI should be evaluated with respect to reperfusion therapy immediately Establish good networks –Preshospital services –Local hospitals –PCI-centra Implement details in guidelines at all levels in the treatment chain
Reperfusion strategy Recommendation IA…. Primary PCI –All when < 90 –120 (?) min. to balloon –All with contraindicasion to thrombolysis –Probably most patients with long chest pain history (> 3 – t??) Thrombolyse to the others; –preferably prehospital and within 3 h from onset of symptoms
Prognostic PCI Recommendation IA PCI within 24 hrs after sucessful thrombolysis –Randomised trials; effect on combined endpoints –No effect on mortality –Discussed…..
Rescue PCI Recommendation IB-IIC Cardiac shock <75 y & <18 h after development of shock (IB) Unsuccessful thrombolysis after min (ECG & clinical eval) (IIC)
Combined strategy, recomm IIB Pretreatment with thrombolysis or Gp-IIb- IIIa-inhibitor before PCI in high-risk? –Insufficient documentation (Garcia, SIAM..) –ASSENT IV; higher mortality with combined treatment (6%)versus primary PCI(3,8%), but positiv for some groups and some weekness in the study –STREAM??
”Facilitated PCI” (thrombolysis before PCI) ASSENT-4 trial, Lancet 2006; 367: PCI: 3,8% Tenecteplase + PCI: 6,0% 30d mort. But, pts with prehospital thrombolysis; ~2%
Pretreatment before primary PCI MONA (morphine, Oxyg, Nitro, ASA 300) Heparin bolus; iv.(70IE/kg iv. ) Clopidogrel 600mg pr. os Evt. Thrombolyse befor transportation (facilitated PCI) when high risk??

STEMI – Do we need more PCI-centers?
