European ST-segment elevation myocardial infarction (STEMI) guidelines recommend prehospital diagnosis to facilitate early reperfusion in patients with STEMI, and they provide recommendations regarding optimal system delay (time from first medical contact (FMC) to the primary percutaneous coronary intervention (PPCI)). There are limited data on achievable system delays in an optimal STEMI system of care using prehospital diagnosis to triage patients with STEMI directly to percutaneous coronary intervention (PCI) centres. We examined the proportion of tentative prehospital STEMI diagnoses established by telemedicine confirmed on hospital arrival, and we determined system delay in patients diagnosed before hospital arrival and triaged directly to the catheterisation laboratory.
Population-based follow-up study.
Central Denmark Region.
15 992 patients diagnosed using telemedicine.
During the study period, a tentative diagnosis of STEMI was established in 1061 patients, of whom 919 were triaged directly to the PCI centre. In 771 (84%) patients, a diagnosis of STEMI was confirmed. Patients transported
