Acute Coronary Syndrome CardioFlux TM Study (ACCMED) (MAGNETO)

Brief Summary:
Approximately 16.5 million people suffer from coronary artery disease (CAD) and about 10 million present each year to emergency departments with symptoms like chest pain and shortness of breath, commonly suggestive of acute coronary syndrome (ACS). To clinically assess ACS risk in these patients, there are typically 2-6 hours of emergency room evaluation, followed by 6-42 hours of an observation period prior to discharge. The clinical pathway includes: 1) 1-3 ECG's; 2) serial troponins (1 and 3 hours vs 1 and 6 hours); and 3) other pertinent diagnostic information, including but not limited to echocardiography, stress testing and/or CT Angiography. Patients who are evaluated, have presented with a low risk for ACS, and maintain negative diagnostic results can potentially be discharged within 6 hours. However, 20%-40% of patients who fall into indeterminate diagnostic categories will require longer observation periods or admission of 12-48 hours which result in the use of expensive imaging and provocative testing, such as stress testing. The purpose of ACCMED is to measure the efficacy of Magnetocardiography (MCG) as a diagnostic tool to rule-in/rule-out myocardial ischemia in patients with suspicion of an acute coronary syndrome who have a HEART Score > 2 and to allow safe and timely disposition of the patient to an appropriate level of care.

Intervention Details:
  • Device: CardioFlux
    Not an intervention

Primary Outcome Measures :
  1. To prove that MCG can accurately diagnose myocardial ischemia [ Time Frame: 1 year ]

    Demonstrate the following:

    1. MCG has a clinically acceptable sensitivity and specificity for the detection of myocardial ischemia. This will be compared to the Gold Standard of index revascularization, ≥70% stenosis in any coronary artery as determined by invasive coronary angiography, or 30-day MACE.
    2. MCG is non-inferior to noninvasive downstream testing (DS) for the identification of patients with myocardial ischemia.
    3. MCG is non-inferior to noninvasive downstream testing (DS) for appropriate referral of patients to invasive coronary angiography with decision to refer the patient to the coronary catheterization laboratory as the Gold Standard.

Secondary Outcome Measures :
  1. To demonstrate that MCG provides value to the traditional HEART score for risk stratification of patients with suspected ACS. [ Time Frame: 1 year ]
