About this study

Patients with heart failure (HF) exhibit greater structural brain alterations and higher dementia risks than the general population. Neural atrophy in nearly every region of medical limbic circuit has been observed in HF patients. Reduction of cerebral blood flow has been suggested as the pathophysiological pathway linking HF and structural brain changes. Indeed, lower cardiac index levels were related to lower cerebral blood flow in older adults without stroke, dementia, or heart failure. A few prior studies have examined the subcortical structural differences in patients with HF compared to controls. Brain volume loss (including putamen and hippocampal volumes) have been reported in patients with low ejection fraction. Significant gray matter loss was found in specific brain regions of HF patients and included structures that serve demonstrated roles in cognitive functions. In the investigator's previous study (Comprehensive Imaging Exam of Convalesced COVID-19 Patients - COVID-19 RELATED SUBMISSION-IRB00252436), involving 100 participants (volunteers with normal heart function (ejection fraction; 50%)), the investigators observed significant correlations between thalamic volumes and ventricular stroke volumes in volunteers. Building on these findings, the investigators intend to expand the research to include individuals with heart failure (HF), employing the same MRI protocol. The study will involve obtaining a set of T1-weighted brain images to measure the volumes of seven subcortical structures. The investigators goal is to explore the relationship between subcortical volumes and cardiac parameters. Additionally, the investigators will examine whether patients with HF experience a more rapid reduction in subcortical volumes compared to those with normal cardiac function (EF;50%).

Read the detailed description

Heart failure (HF) is a multifaceted clinical syndrome characterized by the heart's inability to effectively pump blood to meet the body's demands. This condition often results from various structural or functional cardiac disorders, impacting not only the heart but also multiple organ systems, including the brain, kidneys, lungs, and circulatory system. Patients with heart failure present a spectrum of symptoms that significantly affect quality of life, such as dyspnea and fatigue, and are typically identified by cardiac dysfunction markers like abnormal left or right ventricular filling and elevated filling pressures. Recent advances in diagnostic technologies, particularly in imaging modalities like Cardiovascular Magnetic Resonance Imaging (CMR), have opened new avenues for in-depth exploration of heart failure's underlying pathophysiology. CMR is increasingly used in heart failure management for risk stratification, viability assessment, and diagnosing conditions like myocarditis and cardiomyopathy. This technology enables detailed assessment of myocardial function, structural changes, and interactions with other organ systems. Patients with heart failure exhibit greater structural brain alterations and higher dementia risks than the general population. Neural atrophy in nearly every region of medical limbic circuit has been observed in HF patients. Initial research showed a strong correlation between thalamic volumes and ventricular stroke volumes in healthy volunteers. The investigators plan to extend this study to heart failure (HF) patients using the same MRI methods to assess the connection between subcortical brain volumes and heart health. Additionally, the investigators will explore if HF patients experience a faster decline in these brain volumes than individuals with normal heart function.

  • Objectives:

Primary: To access the correlation of cardiac structure and function to the subcortical volumes in patients with heart failure.

Secondary: To compare the correlation between cardiac structure and function and subcortical volumes in heart failure patients with that in participants with normal heart function.

Questions about this trial

What is this clinical trial studying?

A study testing Magnetic Resonance Imaging with or without Contrast in people with Heart Failure, run by Johns Hopkins University at 2 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 5 inclusion and 8 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 17 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 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?

Subcortical Volumes in Heart Failure (time frame: From enrollment up to 30 days post treatment). 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 17 Jul 2026.
