"Discovery2" Study of Using MCG at Emergency Departments

The purpose of this research is to collect the magnetic signals from the heart to identify features that may help Emergency Department (ED) doctors differentiate high and low risk patients for heart related chest pain.

Inclusion Criteria: * Women and men aged 22 years and older * Participant presenting with signs and symptoms suggestive of NSTE-ACS * In ED chest pain/NSTE-ACS care pathway * HEART Score 4+ * Have received their first troponin result and can accommodate an MCG scan before the second troponin result. Exclusion Criteria: * Unable to provide informed consent * ST elevation myocardial infarction (STEMI) * Active arrhythmia (as seen on the most recent ECG) such as atrial fibrillation, atrial flutter, ventricular tachycardia * Acute hemodynamic instability * Inability to lie supine and still for 5-10 minutes * Known or suspected pregnancy * Unable or unwilling to comply with required follow-up * Metallic passive implants that would make the participant unsuitable for MCG (e.g. spinal implants, metal shoulder replacements, dental implants.. etc.) * Active implantable medical devices (e.g. pacemakers, neurostimulators.. etc.) * Active illegal drug use per history of present illness * Contraindicated for temporary removal of telemetry during MCG scan * Clear non-ischemic cause for symptoms (e.g. trauma, viral infection, valve disease) * Clinical conditions that in the opinion of the Investigator would compromise the safety of the participant or ability to complete the protocol (e.g., exceeds bed weight limit, allergy to adhesives)
