Chest Pain Clinical Trial
Official title:
A Prospective, Blinded, Observational Study to Assess the Accuracy of Magnetocardiography (MCG) as a Tool for Diagnosing Acute Coronary Syndrome (ACS) in Emergency Department Patients Presenting With Acute Chest Pain
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 assess the value of the MCG results in conjunction with the HEART pathway score. This will include looking at the diagnostic test accuracy, sensitivity and specificity of the device when used in conjunction with and without the HEART Pathway score, including versus excluding the troponin level (as the results of this is usually delayed by 45 minutes to 1 hour). In this way, we hope to demonstrate this technology may decrease ED length of stay in chest pain patients and decrease time to diagnosis. The comparison goal standard will be the Cardiology diagnosis, the result of serial troponins, or the ED diagnosis depending on the disposition of the patient. - To estimate ability of MCG for prognostication for major adverse cardiac events (MACE) at 3 days, 7 days, 30 days and 90 days. ;
