About this study

Official title: Evaluation of Potential Myocardial Injury in Patients With Cardiac Implantable Electronic Devices Following Magnetic Resonance Imaging

Researchers are trying to determine if heart injury occurs in subjects with cardiac implantable electronic device (CIED), such as a pacemaker or implantable cardioverter defibrillator (ICD), who undergo a magnetic resonance imaging (MRI).

Read the detailed description

With an aging population and growing indications for both MRI and CIEDs, it is estimated that patients with a CIED will have up to a 75% likelihood to meet some indication for MRI during their lifetime. MRI in patients with CIEDs has been increasingly shown to be a viable option in a variety of clinical circumstances under strict protocols and close monitoring. It is uncertain if MRI results in myocardial injury. Injury could occur due to heating of the lead(s) with myocardial heating and injury occurring at the lead tip.

A previous Mayo study published in 2016 showed no significant changes in cardiac troponin levels in the majority of patients with a CIED when MRI was performed. This study however was done using the older, less sensitive troponin assay. Unpublished data from the Mayo ED showed an increase in diagnosis of acute myocardial injury from 39% to 62% after implementation of the new hs-cTnT assay, reflecting its increased sensitivity. The previous Mayo study was also a retrospective study, and thus the data gathered was not as rigorously controlled as might be ideal.

Questions about this trial

What is this clinical trial studying?

An observational study of Magnetic Resonance Imaging (MRI), run by Mayo Clinic at 1 site 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 1 inclusion and 4 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 5 Jan 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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?

Myocardial injury (time frame: Baseline, 6-24 hours post MRI). 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 5 Jan 2022.
