Genetesis is a cardiac diagnostics company which presents a novel magnetocardiogram (MCG) analysis system called CardioFlux. This investigation presents a new, noninvasive diagnostic option to use MCG for rapid diagnosis of acute coronary syndrome. Data from the Cardioflux system will be compared with stress testing methods as well as the results of cardiac catheterization to identify patients with myocardial ischemia.
This is a prospective observational single-blinded convenience pilot study of 100 patients placed in the Clinical Decision Unit (CDU) for evaluation of chest pain at St. John Hospital and Medical Center (Detroit, MI).
Patients enrolled in the study will also have a 30 and 180 day follow up for analysis of adverse cardiac events.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Acute Chest pain | All patients admitted to the Clinical Decision Unit presenting to the Emergency Department (ED) with chest pain with risk factors suggesting a possible cardiac etiology. |
|
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Magnetocardiography | Diagnostic Test | Study subjects will be placed within a magnetic shielding apparatus. Noninvasive sensors placed over the subject's torso will acquire magnetic field fluctuations generated by cardiac activity, which will then be analyzed for evidence of myocardial ischemia. |
| Measure | Description | Time Frame |
|---|---|---|
| Identification of Active Myocardial Ischemia | Comparison of Magnetocardiography (MCG) and imaging of myocardial magnetic field/current will be performed directly with standard stress testing protocols performed on patients admitted to a cardiac observation unit. | 2 days |
| Identification of Active Myocardial Ischemia | Comparison of Magnetocardiography (MCG) and imaging of magnetic field/current will be directly compared to cardiac catheterization data in those patients who undergo this procedure. | 1 week |
| Measure | Description | Time Frame |
|---|---|---|
| Medium term Adverse Cardiac Events | In patients discharged from the cardiac observation unit with a negative stress test result, how does MCG results correlate with major adverse cardiac events (MACE) at 30 days and 6 months following discharge? MACE will be defined as acute myocardial infarction, coronary revascularization, and all-cause death. | 6 months |
