Determination of Specificity and Sensitivity in Detecting Myocardial Infarction Using the EDE CARDIO BIO-MAP Machine (CARDIO BIO-MAP)
Determination of Specificity and Sensitivity in Detecting Myocardial Infarction Using the EDE CARDIO BIO-MAP Machine, the EDE CARDIO BIO-MAP Study
The goal of this observational study is to learn whether a non-invasive electromagnetic wave scanner (EDE CARDIO BIO-MAP) can help diagnose myocardial infarction (heart attack) in adults (18 years and older) who come to the emergency department with chest pain and suspected myocardial infarction. The main questions it aims to answer are:
- How sensitive and specific is the EDE scanner in diagnosing myocardial infarction (MI) compared with standard blood tests (e.g., cardiac troponin)?
- How sensitive and specific are the immediate blood measurements from a portable lab device compared with conventional hospital laboratory measurements? Researchers will compare the results of the EDE scanner and the portable lab with standard hospital blood test results and the final clinical diagnosis to see how accurately each detects MI.
Participants will:
- Have a research visit (30 minutes to 1 hour) during their emergency care, including a quick scan with the Exponential Deep Examination (EDE) device (attached to a phone or tablet) and a small research blood sample tested on a portable lab device
- Repeat the scan and blood sample 4 to 6 hours later, only if a second blood draw is already needed for their clinical care
- Answer questions about their medical and social history, and allow the study team to collect relevant results from their medical record Scanner results will not be shared with participants or used for their clinical care.

Gedetailleerde beschrijving
Myocardial infarction is a leading cause of death and disability worldwide. Current diagnosis relies on clinical assessment, electrocardiogram, and blood measurement of cardiac biomarkers such as troponin. Faster, non-invasive diagnostic tools could be especially valuable in the emergency setting, where timely intervention is critical.
The Exponential Deep Examination Cardio Bio-Map is a non-invasive device, classified as Class 1 under the European Conformity marking system, that analyzes passive electromagnetic signals (0.1 to 300 gigahertz) using artificial intelligence to measure cardiac biomarkers without a blood draw. Results are available within 50 milliseconds. The device does not collect or store patient data. It produces an immediate printed report, and all data processing occurs locally within Qatar. During the COVID-19 pandemic, the same technology detected the SARS-CoV-2 virus with a specificity of 95.62% and a sensitivity of 93.71% compared with polymerase chain reaction testing and antibody testing. This study will evaluate whether the device can screen for myocardial infarction through measurement of cardiac biomarkers, both in biological samples (in vitro, using a portable laboratory device) and directly in patients (in vivo, using the scanner).
