  7. Pathway: Triage and Transfer for PCI (in STEMI) STEMI patient who is a candidate for reperfusion Initially seen at a non-PCI capable facility Initially seen at a PCI capable facility Initial Treatment with fibrinolytic therapy (Class 1, LOE:A) Send to Cath Lab for primary PCI (Class I, LOE:A) Transfer for primary PCI (Class I, LOE:A) Tempo da angor < 3 h Tempo al pallone > 1 h Basso score rischio / no rischio emorr. Tempo da angor > 3 h Tempo al pallone < 1 h Alto score di rischio / rischio emorragico HIGH RISK Transfer to a PCI facility is reasonable for early diagnostic angio & possible PCI or CABG (Class IIa, LOE:B), High-risk patients as defined by 2007 STEMI Focused Update should undergo cath (Class 1: LOE B) NOT HIGH RISK Transfer to a PCI facility may be considered (Class IIb, LOE:C), especially if ischemic symptoms persist and failure to reperfuse is suspected Prep antithrombotic (anticoagulant plus antiplatelet) regimen Diagnostic angio Medical therapy only PCI CABG 2009 STEMI Focused Update.

  16. PCI “facilitata” e “rescue”: termini obsoleti (molto attuali) I termini “facilitated PCI” e “rescue PCI” non dovrebbero più essere usati “ Contemporary therapeutic choices leading to reperfusion for pts with STEMI can be described without these potentially misleading labels” confondenti rispetto a obiettivo riperfusione Cambio concettuale: la riperfusione è l’obiettivo, non si parlerà più di “facilitazione” e di “rescue”, termini giudicati confondenti e obsoleti che siamo invitati a mandare in cantina ACC/AHA 2009 Joint STEMI/PCI Guidelines Focused Update

  33. HORIZONS-AMI: Results (cont.) • Treatment with bivalirudin compared with UFH plus GP IIb/IIa inhibitors resulted in significantly lower: • 30-day death rates from cardiac causes (1.8% vs. 2.9%; RR 0.62; 95% CI 0.40 to 0.95; p=.03), & • 30-day death from all causes (2.1% vs. 3.1%; RR 0.66; 95% CI 0.44 to 1.00; p=0.047) • At one year, MACE rates were identical, but there was a decrease in all-cause mortality with bivalirudin (3.4% versus 4.8%, p=0.03). bivalirudina - morti a 30 gg - morti a 1 anno
