3 The Transfer for Primary Angioplasty: The Evidences
According to ESC guidelines (and AHA/ACC guidelines too) when primary angioplasty is available in a “timely fashion” and procedure can be performed by an “experienced” operator in a “large volume centre”, primary PCI should be considered the preferred reperfusion strategy However, which is the best modality of reperfusion treatment for patients admitted to community hospitals without invasive facilities is less clear

4 The Importance of Time to Transfer
The time delay for transferring patients to PCI centers could reduce or even nullify the potential benefit of reperfusion Gersh, B. J. et al. JAMA 2005;293:

5 ACC/AHA Guidelines for the Management of Patients With ST-Elevation Myocardial Infarction—Executive Summary A Report of the American College of Cardiology/American Heart Association Task Force on Practice Guidelines (Writing Committee to Revise the 1999 Guidelines for the Management of Patients With Acute Myocardial Infarction) Writing Committee Members: Elliott M.

Smith, Jr, MD, FACC, FAHA                                                          Tuttavia, dal 1990, la commissione di esperti delle 2 principali associazioni di cardiologi americani ha fornito periodicamente alla comunità scientifica delle rasserenanti raccomandazioni che tenessero di conto i numerosi progressi realizzati nel campo della diagnosi e del trattamento dell’IMA. Nel luglio 2004 sono state aggiornate le linee guida compilate nel 1999. (Circulation. 2004;110: )

6 ACC/AHA Guidelines for the Management of Patients with ST-Elevation Myocardial Infarction
Class I. If immediately available, primary PCI should be performed in patients with STEMI (including true posterior MI) or MI with new or presumably new LBBB who can undergo PCI of the infarct artery within 12 hours of symptom onset, if performed in a timely fashion (balloon inflation within 90 minutes of presentation) by persons skilled in the procedure (individuals who perform more than 75 PCI procedures per year). The procedure should be supported by experienced personnel in an appropriate laboratory environment (performs more than 200 PCI procedures per year, of which at least 36 are primary PCI for STEMI, and has cardiac surgery capability). (Level of Evidence: A)                                                          Per quanto riguarda le indicazioni all’angioplastica primaria, (Circulation. 2004;110: )

7 ACC/AHA Guidelines for the Management of Patients with ST-Elevation Myocardial Infarction
Strict performance criteria must be mandated for primary PCI programs so that long door-to-balloon times and performance by low- volume or poor-outcome operators/laboratories do not occur. Interventional cardiologists and centers should strive for outcomes to include: (1) door-to-balloon times less than 90 minutes; (2) TIMI 2/3 flow rates obtained in more than 90% of patients; (3) emergency CABG rate less than 2%; Le linee guida americane oltre alla quantità si preoccupano anche della qualità delle procedure dei singoli centri. Vengono quindi elencati criteri minimi da raggiungere. Tali criteri includono: Un tempo intercorso tra la presentazione e la riperfusione inferiore a 90’ Un flusso epicardico TIMI 2-3 in almeno 90% dei pazienti. La necessità di intervento cardiochirurgico d’urgenza in meno del 2% Il realizzo effettivo della angioplastica in almeno l’85% dei pazienti Una mortalità intraospedaliera inferiore al 7% (4) actual performance of PCI in >85% of patients brought to the lab; (5) risk-adjusted in-hospital mortality rate less than 7% in patients without cardiogenic shock.

32 Angioplasty: Evidences
Transfer for Primary Angioplasty: Evidences Metanalysis considering five randomized Trials (n=2909) (+ CAPTIM, n=3750) showed a benefit of transfer for primary PCI compared to on-site fibrinolysis in term of combined endpoint (death, reinfarction, stroke) Dalby, M. et al. Circulation 2003;108:

33 Asymptomatic patients with STEMI and symptom onset > 12 h
BRAVE-2 Trial: Asymptomatic patients with STEMI and symptom onset > 12 h % 13% Final Infarct size 8% Invasive strategy Conservative strategy Schömig, A. et al. JAMA 2005;293:

34 Should patients with STEMI and symptom onset > 12 h be treated with PCI?
Schömig, A. et al. JAMA 2005;293:

35 Practical Messages The policy of transferring STEMI patients with symptom onset <12 h initially admitted to community hospitals to centres which offer primary PCI seem feasible and safe, with the “useful window for transfer of 90 min”. For patients with STEMI and symptom onset 12 h (8-31% of all patients with STEMI), the transfer from community hospitals to PCI centres could represent a “missed opportunity”. However, more trials are needed to confirm this policy.

36 CONCLUSIONE Indipendentemente dal tipo di “rete interospedaliera” che si viene a realizzare, deve essere perseguito l’obiettivo di garantire il trattamento riperfusivo più rapido ed efficace al “maggior numero possibile di pazienti”.
