Objective: We sought to evaluate the accuracy of emergency medical services (EMS) activation of the cardiac catheterization laboratory (CCL) for patients with ST-elevation myocardial infarction (STEMI) and its impact on treatment intervals from dispatch to reperfusion.
Methods: We conducted a before-and-after cohort study of patients presenting via EMS with prehospital electrocardiogram findings consistent with STEMI. Before August 20, 2007, percutaneous coronary intervention was initiated after patient arrival.
Objectives: We evaluated the impact of emergency physician (EP)-initiated primary percutaneous coronary intervention (PCI) via a single-group page on door to balloon (D2B) interval times in patients with ST-segment elevation myocardial infarction.
Methods: Consecutive ST-segment elevation myocardial infarction patients presenting to the emergency department between February 2004 and September 2008 were divided into 4 groups: group 1, PCI performed on an ad hoc basis after cardiology consultation; group 2, primary PCI activated via a single-group page only on-call cardiology consultation; group 3, primary PCI with EP cardiac catheterization laboratory (CCL) activation via the same page strategy; group 4, prehospital CCL activation based on prehospital diagnostic electrocardiogram. Composite D2B and relevant time intervals were measured for each time group.
Study Objective: Current recommendations indicate that emergency physicians should activate cardiac catheterization laboratory personnel by a single page for ST-segment elevation myocardial infarction (STEMI) patients. We assessed the accuracy of emergency physician cardiac catheterization laboratory activations, angiographic findings, outcomes, and treatment times among patients with and without STEMI.
Methods: We classified the appropriateness and outcomes of consecutive emergency physician STEMI pages between June 2006 and September 2008.
