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
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;293:979-986
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.

ACC/AHA Guidelines for the Management of Patients with ST-Elevation Myocardial Infarction Class I.If immediately available, primaryPCI should be performed in patients with STEMI (including trueposterior MI) or MI with new or presumably new LBBB who canundergo PCI of the infarct artery within 12 hours of symptomonset, if performed in a timely fashion (balloon inflation within90 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 inan appropriate laboratory environment (performs more than 200PCI procedures per year, of which at least 36 are primary PCIfor STEMI, and has cardiac surgery capability). (Level of Evidence:A) (Circulation. 2004;110:588-636.)
ACC/AHA Guidelines for the Management of Patients with ST-Elevation Myocardial Infarction Strictperformance criteria must be mandated for primary PCI programsso that long door-to-balloon times and performance by low-volumeor poor-outcome operators/laboratories do not occur. Interventionalcardiologists and centers should strive for outcomes to include: (1) door-to-balloon timesless than 90 minutes; (2) TIMI 2/3 flow rates obtained in more than 90% of patients; (3) emergencyCABG rate less than 2%; (4) actual performance of PCI in >85% of patientsbrought to the lab; (5) risk-adjusted in-hospitalmortality rate less than 7% in patients without cardiogenicshock.

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.

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;293:2865-2872
Should patients with STEMI and symptom onset > 12 h be treated with PCI? Schömig, A. et al. JAMA 2005;293:2865-2872
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.
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”.
