The Ischemia Modified Albumin In Diagnosing Ischemic New Events (IMAgine)
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
The purpose of the study is to evaluate the utility of Ischemia Modified Albumin (IMA) for risk stratification in patients presenting with chest discomfort and possible ischemic heart disease, and to evaluate the diagnostic and prognostic implication for IMA for major adverse cardiac events.

Accepts Healthy Volunteers:
Patients who present in the emergency department at the listed institutions with suspected ischemic signs and or symptoms (chest pain) will be eligible for participation in the study as long as they meet inclusion and exclusion criteria and sign an informed consent.
Patients with primary complaints of chest discomfort or patients with symptoms indicative of a moderate to high probability for unstable angina clinically indicated reason for evaluation for ACS in the Emergency Department meeting tyhe following inclusion criteria will be enrolled:
Age >=21 years
Presentation within two hours of relief of most recent episode of chest pain or presence of on-going symptoms suggestive of coronary ischemia, which should be at least 10 minutes in duration.
Patients being evaluated for suspected ischemic signs and or symptoms (chest pain) at the time of presentation according to routine standard of care institutional chest pain protocol/pathway.
Administration of thrombolytic medication prior to first (presentation) blood draw
Acute coronary syndrome (ACS) secondary to supply/demand inequity (i.e. known anemia, tachycardia, - defined as HR greater than 150 bpm, known sepsis, hypotension, defined as blood pressure < 90 mmHg).
Established diagnosis of liver cirrhosis
Other acute ischemic sources (ongoing severe claudication, mesenteric ischemia, acute TIA/CVA)
Renal failure requiring dialysis
Greater than 2 hours from relief of the most recent episode of chest pain or signs and symptoms suggestive of coronary ischemia.
