ESC-ERC recommendations for the use of automated external defibrillators (AEDs) in Europe

The use of automated external defibrillators (AEDs) has a major impact in the management of cardiac arrest and substantial implications for public health. It is therefore important for the European Society of Cardiology (ESC) and the European Resuscitation Council (ERC) to join forces to develop European recommendations for legislation on defibrillation, for training in AED use and for the development of AED community programmes. To fulfil these objectives a Policy Conference was organised jointly by ESC and ERC in December 2002 at the European Heart House in Sophia Antipolis, France. The present document is the result of that policy conference and it has four key objectives: to provide a critical appraisal of the studies published in the scientific literature on the use of AEDs. To present data on the status of legislation/organisation of defibrillation by non-medically qualified rescuers in Europe. To promote recommendations for the organisation of AED programmes in Europe that were collected and discussed during the policy conference. To identify the areas in which more research is needed before evidence based guidelines for the use of AEDs can be developed

Efficacy and safety of tenecteplase in combination with the low-molecular-weight heparin enoxaparin or unfractionated heparin in the prehospital setting: the Assessment of the Safety and Efficacy of a New Thrombolytic Regimen (ASSENT)-3 PLUS randomized trial in acute myocardial infarction.

BACKGROUND: The combination of a single-bolus fibrinolytic and a low-molecular-weight heparin may facilitate prehospital reperfusion and further improve clinical outcome in patients with ST-elevation myocardial infarction. METHODS AND RESULTS: In the prehospital setting, 1639 patients with ST-elevation myocardial infarction were randomly assigned to treatment with tenecteplase and either (1) intravenous bolus of 30 mg enoxaparin (ENOX) followed by 1 mg/kg subcutaneously BID for a maximum of 7 days or (2) weight-adjusted unfractionated heparin (UFH) for 48 hours. The median treatment delay was 115 minutes after symptom onset (53% within 2 hours). ENOX tended to reduce the composite of 30-day mortality or in-hospital reinfarction, or in-hospital refractory ischemia to 14.2% versus 17.4% for UFH (P=0.080), although there was no difference for this composite end point plus in-hospital intracranial hemorrhage or major bleeding (18.3% versus 20.3%, P=0.30). Correspondingly, there were reductions in in-hospital reinfarction (3.5% versus 5.8%, P=0.028) and refractory ischemia (4.4% versus 6.5%, P=0.067) but increases in total stroke (2.9% versus 1.3%, P=0.026) and intracranial hemorrhage (2.20% versus 0.97%, P=0.047). The increase in intracranial hemorrhage was seen in patients >75 years of age. CONCLUSIONS: Prehospital fibrinolysis allows 53% of patients to receive reperfusion treatment within 2 hours after symptom onset. The combination of tenecteplase with ENOX reduces early ischemic events, but lower doses of ENOX need to be tested in elderly patients. At present, therefore, tenecteplase and UFH are recommended as the routine pharmacological reperfusion treatment in the prehospital setting
