This study demonstrated that a regionalized prehospital system for STEMI patients could achieve the recommended 90-min interval benchmark for PCI, while giving timely access to PCI to rural populations that would not otherwise have access to this treatment.
Through recognition of transient ST-segment changes during transport via the prehospital serial 12-lead ECG system, STEMI was identified in 8% of suspected STEMI patients who had an initial no-STEMI ECG. Key words: electrocardiography; emergency medical services; ST-elevation myocardial infarction; prehospital dynamic ECG.
CLINICIAN'S CAPSULE What is known about the topic? ST-elevation myocardial infarction (STEMI) patients transported by ambulance are at risk for adverse events. What did this study ask? What is the impact of transport time on the occurrence of adverse events in the presence of basic life support paramedics? What did this study find? Transport time is not associated with a higher risk of adverse events. Why does this study matter to clinicians? Largest investigation of adverse events in a Canadian cohort of STEMI patients transported by ambulance.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
