Multivariable analysis estimating the treatment effect of reperfusion therapy with PCI or fibrinolysis based on increasing PCI-related delay Pinto, D. S. et al. Circulation 2006;114:2019-2025 Copyright 2006 American Heart Association
THE WHOLE PICTURE Symptom onset EMS call Arrival at PCI center PPCI Fieldtriaged to a PCI center Patient delay Transportation delay Treatment delay D2B delay Health Care System delay Arrival at local hospitall Departure from local hospital Arrival at PCI center PPCI Transferred from local hospitals Patient delay Transportation delay Local hospital delay Interhospital delay Health Care System delay D2B delay Treatment delay
E2B First Medical Contact (EMS, or ER if patient drives self to hospital) to Balloon Time D2B, though heavily emphasized as Quality measure, is only part of the story! Our goal is E2B less than 90 minutes
PATIENT DELAYS Community Education programs It s called heartburn because although it could just be burning from acid reflux it could also be your heart! Time is Muscle Call 911: Do not drive yourself to the ER! EMS can diagnose and start treatment immediately
EARLY ACTIVATION OF STEMI ALERT BY EMS Must empower EMS to make this call! Reduces PCI hospital D2B: Get the team in! Allows local hospitals to be bypassed EMS education is crucial, and very effective 15 lead EKG: Posterior or RV MI We welcome EMS paramedics in Cath Lab
NON PCI HOSPITALS: DIDO Goal: Door In Door Out within 30 minutes Interchangeable equipment: stretchers No drips: So no need to change IV tubing/pumps at transfer points Recognize potential tension between DIDO and E2B: ground vs. air transport?
PROTOCOLS: KISS! Chew 4 baby aspirins (total about 325 mg) Plavix 600 mg load Heparin 5,000 units IV, not weight-adjusted, no drip! SL NTG if BP allows, no IV drip! (coronary spasm) IV beta blockers only if needed for HTN/tachycardia! (causes hypotension, bradycardia, and shock!)
D2B Considerations STEMI RN: a GMH innovation! Crucial role in coordination, transport, and in Cath Lab Be aware of door time! Address Infarct Related Artery first? Simultaneous STEMI S:? Triage low risk patient to lysis and PCI--**Communication between ER MD and cardiologists is essential** Reversal of cardiogenic shock must take precedence over achieving D2B
False positives? Inherent tension also between low D2B and potential situations that do not represent STEMI Pros and cons of accepting patients directly to Cath Lab: role of non cardiologists Need low threshold for calling STEMI Alert Constant reassurance of MD s and EMS about this new paradigm Recurring 12 lead EKG training for EMS, ER MD s, RN s, EKG techs

SOME CONCLUSIONS The first priority is prompt reperfusion By any modality! D2B--and even E2B times--are only part of the story! We (patients, EMS, aircrews, ER MD s, cardiologists, Cath Lab Techs, nurses indeed, all GMH physicians) need to be all in to work TOGETHER to minimize delays!!
IT S AMAZING THIS ACTUALLY WORKS!
