About this study

Official title: Magnetocardiography as a Noninvasive Diagnostic Strategy for Suspected Coronary Microvascular Dysfunction

According to the Women's Ischemic Syndrome Evaluation database, there are approximately 3 to 4 million women and men who present with signs and symptoms that are suggestive of myocardial ischemia, however they have no obstructive coronary artery disease (INOCA). INOCA is defined as patients presenting with signs or symptoms of ischemia but no obstructive artery disease. Women are more likely than men to die from cardiovascular disease and more likely to present with no obstructive coronary artery disease. Patients who present with signs and symptoms suggestive of INOCA/MINOCA are also presenting with Coronary Microvascular Dysfunction (CMD). Coronary Microvascular Dysfunction is a dysfunction in the epicardial and/or microvascular endothelial and/or nonendothelial that limits myocardial perfusion. Today, there is no routinely offered/available noninvasive test that is used for the diagnosis of CMD, significantly hindering the ability to identify the disease in the standard of care. Magenetocardiography (MCG) has the opportunity to use its noninvasive imaging techniques to provide early management of CMD. Magnetocardiography (MCG) is a noninvasive imaging modality that has been extensively studied, over the past several decades, as a diagnostic imaging solution for various forms of cardiovascular disease. MCG measures the magnetic field that arises from the electrical activity of the heart's pacemaker activity, the very same activity which yield surface electric field potentials as measured by the electrocardiogram. Since MCG is a functional assessor of repolarization heterogeneity, it is hypothesized that MCG may be a useful frontline diagnostic to identify CMD in patients who would otherwise have normal coronary CT angiograms and/or stress tests. The proposed study intends to study the diagnostic accuracy of MCG in this population, with the goal of providing early and noninvasive insights for management of CMD. There will be a 12-month duration of the study where the investigators propose to collect MCG scans from approximately 150 patients who present to the Genetesis facility for a 15-minute CardioFlux scan appointment.

Questions about this trial

What is this clinical trial studying?

An observational study of Coronary Microvascular Dysfunction and Ischemic Non-Obstructive Coronary Artery Disease, run by Genetesis Inc. at 4 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 16 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 31 Aug 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Diagnostic accuracy of CardioFlux (time frame: 12 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 31 Aug 2023.
