A Prospective Pilot Study to Evaluate a New Marker of Ischemia in Chest Pain Triage

Study Overview
=================
Brief Summary
-----------------
A Single-center prospective pilot study enrolling chest pain patients. CD 26 measurement will be performed and compared to troponin µs for early triage of these patients. This novel biomarker of myocardial ischemia (CD26) will be measured at the time of first medical contact (T0) and after 30 min simultaneously o troponin Ic. All patients aged over 18 years with chest pain which may be related to acute coronary syndrome requiring pre hospital medical contact through the Emergency Medical Service.

Detailed Description
-----------------
First objectives: demonstrating the early positivity of CD26 compared to ultra-sensitive troponin.
