Role of Cardioflux in Predicting Coronary Artery Disease (CAD) Outcomes

Brief 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.

Condition or disease Intervention/treatment
Coronary Artery Disease Diagnostic Test: CardioFlux Magnetocardiography

Detailed 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.

Group/Cohort Intervention/treatment
Standard Coronary Artery Disease Screening
All patients presenting for standard coronary artery disease screening will undergo additional imaging with CardioFlux MCG. These patients will be followed longitudinally for short and long term MACE.
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.

Primary Outcome Measures :
  1. Percentage study subjects having coronary Revascularization [ Time Frame: 1 year ]
    Patient follow up will be performed to find the incidence of coronary revascularization at 30 days and 1 year.

  2. Percentage of study subjects having Major Adverse Cardiac Events [ Time Frame: 1 year ]
    Patients will have follow up to determine the occurrence of MACE, defined as nonfatal stroke, nonfatal myocardial infarction, and cardiovascular death

  3. Incidence of study subjects with endpoint of death [ Time Frame: 1 year ]
    All cause mortality will be recorded at end of follow up period for the entire study population.

Secondary Outcome Measures :
  1. Comparison of MCG with Stress testing [ Time Frame: 30 days ]
    Comparison with nuclear stress testing (SPECT) will be performed, with statistical analysis including sensitivity, specificity, NPV, and PPV

  2. Comparison of MCG with Cardiac CT angiography (CCTA) [ Time Frame: 30 days ]
    Comparison with CCTA will be performed for those having this test, with statistical analysis including sensitivity, specificity, NPV, and PPV
