Key result
A novel magnetocardiography device distinguished post-myocardial infarction patients from young healthy controls with an area under the curve of 95%, achieving 100% sensitivity and 76% specificity.
Why the study?
To evaluate a portable, unshielded magnetocardiograph and identify key scan parameters sensitive to cardiac pathology for use in future diagnostic studies.
Can a portable, unshielded magnetocardiograph (MCG) identify parameters sensitive to cardiac pathology to distinguish between patients with recent myocardial infarction and healthy volunteers?
Population
50 patients with confirmed MI within the past 12 weeks and 46 volunteers with no history of cardiac disease
Comparison
Patients with confirmed MI vs volunteers with no history of cardiac disease

Can a portable, unshielded magnetocardiograph (MCG) identify parameters sensitive to cardiac pathology to distinguish between patients with recent myocardial infarction and healthy volunteers?
Effect estimate: AUC 95%
A novel portable, unshielded magnetocardiography device can identify parameters sensitive to cardiac pathology, such as LVEF, distinguishing post-MI patients from healthy controls.
Beadle et al. (2021) conducted a case-control in Myocardial infarction (n=96). Magnetocardiography (MCG) vs. Young healthy controls was evaluated on Discrimination between post-MI patients and young healthy controls using PC1 probability score (AUC 95%). A novel magnetocardiography device distinguished post-myocardial infarction patients from young healthy controls with an area under the curve of 95%, achieving 100% sensitivity and 76% specificity.
