Magnetocardiography Using a Novel Analysis System (Cardioflux) in the Evaluation of Emergency Department Observation Unit Chest Pain Patients

January 26, 2022 updated by: Genetesis Inc.

Genetesis is a cardiac diagnostics company which presents a novel magnetocardiogram (MCG) analysis system called CardioFlux. This investigation presents a new, noninvasive diagnostic option to use MCG for rapid diagnosis of acute coronary syndrome. Data from the Cardioflux system will be compared with stress testing methods as well as the results of cardiac catheterization to identify patients with myocardial ischemia.

This is a prospective observational single-blinded convenience pilot study of 100 patients placed in the Clinical Decision Unit (CDU) for evaluation of chest pain at St. John Hospital and Medical Center (Detroit, MI).

Patients enrolled in the study will also have a 30 and 180 day follow up for analysis of adverse cardiac events.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

This study is a pilot study of 100 patients over the age of 18 years who are to be placed in the CDU for evaluation of chest pain of possible cardiac origin will be eligible for the MCG-CF scan based on eligibility criteria criteria.

Description

Inclusion Criteria: Low and intermediate risk ED patients presenting with chest pain of possible cardiac origin who have a negative first troponin result and non-diagnostic ECG that are to be placed in the Cardiac Diagnostic Unit (CDU) for further evaluation.

Exclusion Criteria:

  1. ≤ 18 years of age
  2. Patients unable to fit into device
  3. Non-ambulatory patients
  4. Patients with any implantable device or metal in the thorax area (e.g. pacemaker, AICD, bullet fragments in thorax)
  5. Patients with claustrophobia
  6. Pregnant women
  7. Poor candidate for follow-up
  8. Prisoners
  9. Repeat participants

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Acute Chest pain
All patients admitted to the Clinical Decision Unit presenting to the Emergency Department (ED) with chest pain with risk factors suggesting a possible cardiac etiology.
Diagnostic test: Magnetocardiography
Study subjects will be placed within a magnetic shielding apparatus. Noninvasive sensors placed over the subject's torso will acquire magnetic field fluctuations generated by cardiac activity, which will then be analyzed for evidence of myocardial ischemia.
Other Names:
  • Cardioflux Scan

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Identification of Active Myocardial Ischemia
Time Frame: 2 days
Comparison of Magnetocardiography (MCG) and imaging of myocardial magnetic field/current will be performed directly with standard stress testing protocols performed on patients admitted to a cardiac observation unit.
2 days
Identification of Active Myocardial Ischemia
Time Frame: 1 week
Comparison of Magnetocardiography (MCG) and imaging of magnetic field/current will be directly compared to cardiac catheterization data in those patients who undergo this procedure.
1 week

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Medium term Adverse Cardiac Events
Time Frame: 6 months
In patients discharged from the cardiac observation unit with a negative stress test result, how does MCG results correlate with major adverse cardiac events (MACE) at 30 days and 6 months following discharge? MACE will be defined as acute myocardial infarction, coronary revascularization, and all-cause death.

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
