About this study

The purpose of this collaboration is to establish a multi-modality image database including coronary angiograms, optical coherence tomography (OCT), computed tomography angiograms (CTA) and cardiac magnetic resonance imaging (CMR) for future studies. The main goal of this collaboration is to create a resource to promote further understanding of the pathobiology of atherosclerosis through image analysis.

Read the detailed description

The purpose of this collaboration is to establish a multi-modality image database including coronary angiograms, optical coherence tomography (OCT), computed tomography angiograms (CTA) and cardiac magnetic resonance imaging (CMR) for future studies. About one thousand patients who underwent coronary angiography with OCT and had a CTA prior to catheterization at Tsuchiura Kyodo General Hospital (TKGH) in Japan, will be included. A subset of these patients also had CMR. The main goal of this collaboration is to create a resource to promote further understanding of the pathobiology of atherosclerosis through image analysis.

Questions about this trial

What is this clinical trial studying?

An observational study of Atherosclerosis, run by Massachusetts General Hospital at 2 sites in 2 countries.

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 1 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: under way, not looking for participants, as of the sponsor's last update on 29 Dec 2025. 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, Japan. 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?

This study is still under way. Results are not available in the source record yet.

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?

Major Adverse Cardiac Events (MACE) (time frame: 1 Year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04523194, which also lists 19 linked publications.

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 29 Dec 2025.
