Multi-Markers In the Diagnosis of Acute Coronary Syndrome

This is a prospective clinical study designed to procure blood samples from patients who present to the Emergency Department with suspected ACS (Acute Coronary Syndrome). Subjects enrolled in this study will sign and informed consent and have 4 blood samples drawn at different time points during their emergency department visit. In addition, data will be collected about the patient's health history, hospital procedures, and final diagnosis. The enrolling center will also contact the patients at 30-days, 3 months and 6 months to inquire about their condition and survival. Blood samples collected in this study will be sent to the sponsor organization for long-term storage and analysis in the future for novel blood markers as they become available. No genetic testing will be conducted on these samples.
