<li>
The ADAPT (2-Hour Accelerated Diagnostic Protocol to Assess Patients With Chest Pain Symptoms Using Contemporary Troponins as the Only Biomarker) trial was a prospective observational validation study designed to assess a predefined ADP (Accelerated Diagnostic Protocol)</li>
<li>
A low risk patient in this ADP was defined by TIMI 0, ECG w/no ischemic changes, and negative troponin at 0-and 2-hours after presentation</li>
<li>
Primary endpoint was assessment of any major adverse cardiac event (MACE)</li>
<li>
Of 1,975 patients enrolled, 302 (15.3%) had a MACE</li>
<li>
ADP classified 392 patients (20%) as low risk and only 1 (0.25%) had a MACE</li>
<li>
ADP had a sen 99.7%, NPV 99.7%, spec 23.4%, and PPV 19.0%</li>
<li>
Despite ADP identifying patients as low risk for MACE standard of care still requires rapid early outpatient follow-up or further inpatient testing </li>
