Guidelines and Data Collection • Circulation. 2004;110:588-636 • Eur Heart J. 2003; 24: 28–66
ACC/AHA Guidelines Goal: ‘ischaemic time’ < 120 mins (Sx to lysis or PCI) EMS Prehosp lysis < 30 min of arrival at scene Non PCI centre Door to needle < 30 min If < 90 min (total) to balloon or if transport will not add more than 60 to time to balloon v local lysis PCI centre Door to balloon <90 min
ACC/AHA Guidelines Circulation. 2004;110:588-636 • Fibrinolysis preferred if • Early presentation < 3hr (and delay to PPCI) • PPCI not an option • Lab busy • No lab / inappropriate lab • Delay to invasive strategy • > extra 1 hr over lysis time • > 90 min medical contact to balloon
ACC/AHA Guidelines Circulation. 2004;110:588-636 • PPCI Preferred if • Skilled PCI service with surgical backup • Operator > 75 Primary PCI pa • Team > 36 Primary PCI pa • Timings as before • High risk for STEMI • Shock • Killip ≥ 3 • Contraindication to lysis • Late presentation (> 3 hours) • STEMI diagnosis in doubt
ESC Guidelines Eur Heart J. 2003; 24: 28–66 • Fast Track patients (clear indication for reperfusion) • Door to needle < 20 min • Door to Balloon < 60 min
