Quinn et al (2014) investigated patterns of prehospital Electrocardiogram (PHECG) use whilst also determining its association with processes and outcomes of care in patients with ST-elevation myocardial infarction (STEMI) and non-STEMI.


Utilising a population-based linked methodology from the national myocardial infarction registry, 288,990 patient records were included. The findings from this study demonstrate a survival advantage in STEMI and non-STEMI patients when PHECG was used. This was the first study in the world to report an associated mortality benefit and was highlighted in subsequent international guidelines for heart attack care.
