The purpose of the research is to see if patients that come to the Emergency Department with chest pain can be more accurately and more quickly diagnosed by magnetocardiography (MCG) to see if their chest pain is caused by coronary ischemia (reduced blood flow to the heart) in patients with normal or have non-specific changes on the ECG vs other causes by other reasons.
Hypothesis: MCG can accurately, and in real-time, identify an acute coronary syndrome for patients presenting to the emergency department (ED) with chest pain and is faster than current practice. Aims, purpose, or objectives: Our primary objective is to measure the diagnostic accuracy of the Mesuron Avalon-H90 MCG device to detect ACS (unstable angina, NSTEMI) in Emergency Department patients who present with acute chest pain when compared to the current goal standard. Our secondary objectives are as follows: * To study the ability of MCG to rule in or rule out ACS in real-time. We will ass…
Inclusion Criteria: * Patients presenting to the ED with acute chest pain when an ACS is on the differential diagnosis. * Patient willing and able to give informed consent. Exclusion Criteria: * ST elevation \> 1 mm on any two contiguous ECG leads. * Hemodynamic instability (SBP \>220 or \<80, HR \>160). * Pregnant patients. * Incarcerated patients (FMC patients). * Patients with a pacemaker or defibrillator. * Metal implants in the body (that are not MRI safe). * Patients that are unable to lie down in the MCG machine or stay still. * Patients who are unable to understand the informed cons…
