Patients receiving serial routinely available cardiac biomarker testing in a core laboratory setting using Troponin T. (Roche Centaur)

Patients will receive the Point of Care testing intervention using serial cardiac biomarker testing at the bedside including myoglobin, Troponin I and CK-MB. (Triage Cardiac Panel, Alere)

The investigators will implement 6 months of randomized testing periods, 2 weeks each. During this 2 week block, cardiac biomarkers will be tested at the bedside in the ED using the Triage Cardiac Panel that will test for CK-MB, Myoglobin, and Troponin I.

Each blood sample that is take for point of care testing will be saved. The plasma from the saved sample will be frozen and the sample will be sent to an off-site testing center for high sensitivity troponin testing.

All patients will be followed at the 30-day mark and those patients who are discharged home from the ED will be followed within 48 hours as well.
