Overview

Supports prehospital ECG with ED notification for faster fibrinolysis in AMI; confirms substantial door-to-needle reductions but leaves mortality benefit open.

Structured PICO

Does prehospital 12-lead electrocardiogram interpretation and advance ED notification improve treatment time intervals and mortality in patients with acute myocardial infarction?

P
Population
Patients with acute myocardial infarction (AMI) from 5 controlled trials
I
Intervention
Prehospital 12-lead electrocardiogram (PHECG) interpretation and advance emergency department (ED) notification
C
Comparator
Standard emergency medical services (EMS) care
O
Outcome
Treatment time intervals (door-to-needle interval, on-scene time) and all-cause mortalitysurrogate

Prehospital 12-lead ECG and advance ED notification significantly reduces in-hospital time to fibrinolysis for patients with acute myocardial infarction.
