Myeloperoxidase and Multi-Markers In the Diagnosis of Diagnoses of Acute Coronary Syndrome (MIDAS) - Sample Procurement

Acute Coronary Syndrome (ACS)

Heart, Cardiac, Acute Coronary Syndrome, Sample Procurement

The purpose of the study is to procure blood samples from patients who present to the Emergency Department with suspected ACS (Acute Coronary Syndrome).

This is a prospective, multi-center, observational, and sample procurement study of adult subjects presenting to an Emergency Department (ED) in whom ACS is in the differential diagnosis. Subjects must present to one of the participating EDs within 6 hours or less from the time of symptom onset, and must have experienced at least 30 minutes of chest discomfort. Those ED patients with possible ACS who meet the inclusion/exclusion criteria will be approached for study enrollment by trained research personnel. The patient's diagnostic work-up and treatment will continue per the standards of the treating institution. As indicated by their clinical presentation, all subjects in the study will have objective cardiac testing for evidence of coronary artery disease (CAD) during or in close proximity to the index ED visit or hospital admission. For this study, objective cardiac testing will consist of one of the following tests: exercise treadmill, coronary angiography, myocardial stress imaging, stress magnetic resonance imaging (MRI), sestamibi scan, or dobutamine echocardiogram. Cardiac events and procedures, such as angioplasty-stenting and coronary artery bypass surgery (CABG), will be recorded during the index ED visit, hospitalization and post-hospital follow-up period. Subjects will have a 30-day and 6-month follow-up contact by phone to collect this information on cardiac events, procedures, and survival.
