Diagnostic accuracy of early biomarkers for acute coronary syndrome (ACS) (2012)

Background: Current practice for suspected ACS involves troponin testing 10-12 hours after symptom onset to diagnose myocardial infarction (MI).

Aim: To estimate the diagnostic accuracy of early biomarkers for MI to determine if an earlier, accurate decision was possible

Rationale: Early discharge of patients with no or low risk of ACS will result in cost savings and reduced healthcare and patient burden.
