Background: Emergency medical services (EMS) transportation is associated with shorter door-to-balloon (DTB) time in patients with ST-segment elevation myocardial infarction (STEMI). In addition to EMS transportation, prehospital notification of STEMI by EMS to receiving hospital might be able to further shorten DTB time. We evaluated the impact of STEMI notification on DTB time as well as infarct size.
Methods: We performed a retrospective analysis of consecutive patients with anterior wall STEMI who underwent emergent coronary angiography. We excluded patients who presented with cardiac arrest and those who were transferred from non-percutaneous coronary intervention-capable hospitals. Mode of transportation were categorized into the 3 groups: (1) EMS transport with STEMI notification, (2) EMS transport without STEMI notification, and (3) self-transport. Baseline characteristics, laboratory data, left ventricular ejection fraction (LVEF), and DTB time were compared among the 3 groups.
Results: A total of 148 patients were included in the final analysis. Of the 148 patients, 56 patients arrived by EMS transport with STEMI notification, 56 patients arrived by EMS transport without STEMI notification, and 36 patients arrived by self-transport. Patients who arrived by EMS transport with STEMI notification had the shortest DTB time among the 3 groups. Patients who arrived by EMS transport with STEMI notification had smaller infarct size, as indicated by lower peak creatine kinase value and higher LVEF, compared with those who arrived by EMS transport without STEMI notification.
Conclusion: Emergency medical services transport with STEMI notification was associated with shorter DTB time and smaller infarct size in patients with anterior wall STEMI.

Background Rapid treatment of ST-elevation myocardial infarction (STEMI) patients with primary percutaneous coronary intervention (PCI) significantly reduces morbidity and mortality rates. Recent studies emphasize the importance of reducing total ischemic time, making first-medical-contact-to-balloon (FMCTB) time a key performance indicator. To improve FMCTB times in patients brought to the Emergency Department (ED) by Emergency Medical Services (EMS), we implemented a "Direct to Lab" (DTL) workflow during the following conditions: weekday daytime hours, when the lab is fully staffed, and for hemodynamically stable STEMI patients presenting via EMS.

Background: An important method employed to reduce door to balloon time (DTBT) for ST segment elevation Myocardial Infarctions (STEMIs) is a prehospital MI alert. The purpose of this retrospective study was to examine the effects of an educational intervention using a novel decision support method of STEMI notification and prehospital electrocardiogram (ECG) transmission on DTBT.
Methods: An ongoing database (April 4, 2000 - present) is maintained to track STEMI alerts.
Background Prehospital activation of the cardiac catheter laboratory is associated with significant improvements in ST-segment-elevation myocardial infarction (STEMI) performance measures. However, there are equivocal data, particularly within Australia, regarding its influence on mortality. We assessed the association of prehospital activation on performance measures and mortality in patients with STEMI treated with primary percutaneous coronary intervention from the Queensland Cardiac Outcomes Registry (QCOR).

Importance: Treatment of ST-segment elevation myocardial infarction (STEMI) in rural settings involves thrombolysis followed by transfer to a percutaneous coronary intervention-capable hospital. The first step is accurate diagnosis via electrocardiography (ECG), but one-third of all STEMI incidents go unrecognized and hence untreated.
Objective: To reduce missed diagnoses of STEMI.
