The effect of media campaigns, patient characteristics, and presenting symptoms on prehospital delay in myocardial infarction patients: A prospective cohort study

Delays in reperfusion therapy for myocardial infarction (MI) are associated with increased mortality and morbidity, and most of this delay is due to delay in patients initiating contact with emergency services. This study assesses the impact of the Australian National Heart Foundation media campaign and identifies patient characteristics and presenting symptoms that may contribute to delay.
