Clinical Trial Summary

This single-center clinical trial is designed to evaluate the CardioFlux magnetocardiograph diagnostic imaging system to predict major adverse cardiac events (MACE) in patients referred for evaluation for coronary artery disease.

Description:

This is a single-center, prospective, observational cohort trial to form a registry data set. Patients presenting for cardiac stress testing utilizing Single Photon Emission Computed Tomography (SPECT), cardiac CT angiography (CCTA), or cardiac catheterization will be offered to enroll in the registry and provide informed consent to undergo imaging with a CardioFlux magnetocardiography (MCG) prior to their procedure. Multiple studies have shown that MCG accuracy is quite high in identifying patients with symptomatic coronary artery disease. This difference is dramatic enough to prove superiority over standard ECGs in diagnosis of vital ischemic and infarction parameters. Genetesis presents a novel MCG analysis system called CardioFlux (CF). This modality takes less than five minutes to complete, is radiation-free, and is an easy to operate system. This clinical trial will enroll patients of all cardiac risk levels presenting for various modalities of cardiac diagnostic testing to have CardioFlux scanning in addition to standard of care. Results will be interpreted and compared to the immediate results of nuclear (SPECT) stress testing, cardiac CT angiography, or cardiac catheterization. Participants will be followed up at 30 days and 1 year via phone call or chart review. 30 day and 1 year MACE will be recorded and correlated with initial CardioFlux MCG results. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and overall accuracy will be calculated of CardioFlux relative to the incidence of MACE, and in comparison to the above diagnostic modalities.

Related Conditions & MeSH terms

• Coronary Artery Disease
• Coronary Disease
• Myocardial Ischemia

Intervention

Diagnostic Test:
• CardioFlux Magnetocardiography
All patients enrolled and receiving standard screening tests for CAD will undergo a 2 minute scan with MCG. It will be determined if MCG scanning can provide equal or superior accuracy to predict MACE than standard testing.
