About this study

Official title: Evaluation of Atherosclerotic Plaque Progression by Coronary Computed Tomography Angiography and Intracoronary Imaging Techniques in Patients With Coronary Artery Disease

This is a combined cohort study with retrospectively and prospectively enrolled coronary artery disease (CAD) patients. All the patients will undergo clinical follow-up for up to 5 years, and repeat coronary CTA will be conducted after 2 years. Comprehensive morphological and functional plaque analysis will be performed. The impact of these morphological and functional parameters, alongside cardiometabolic factors and pharmacological treatments on plaque progression and the occurrence of major adverse cardiovascular events (MACEs) will be analyzed. In addition, intracoronary imaging techniques will be used to improve the accuracy of plaque analysis by coronary CTA.

Read the detailed description

This is a combined cohort study with retrospectively and prospectively enrolled patients. Subjects with CAD detected by coronary CTA are consecutively enrolled. All the patients will undergo clinical follow-up for up to 5 years. Repeat coronary CTA will be conducted after 2 years. For patients referred to invasive coronary angiography, intracoronary imaging techniques, such as intravascular ultrasound (IVUS), optical coherence tomography (OCT), and near infrared spectroscopy (NIRS) will be performed. For all the prospectively enrolled patients, plasma and serum blood samples will be collected.

The purpose of this study is to investigate the natural history of coronary atherosclerotic plaques in this population. Comprehensive morphological plaque analysis will be performed to evaluate total atheroma volume (TAV), percent atheroma volume (PAV), plaque composition, high risk plaque features, and characteristics of perivascular adipose tissue (PVAT). Functional analysis will also be conducted to calculate hemodynamic parameters such as wall shear stress (WSS), oscillatory shear index (OSI), relative residence time (RTT), transverse WSS (transWSS), axis plaque stress (APS), fractional flow reserve (FFR), and δFFR across lesions. The associations of these morphological and functional parameters with plaque progression and the onset of major adverse cardiovascular events (MACEs) will be analyzed. In addition, the impact of pharmacological treatments and the levels of cardiometabolic factors on coronary plaque progression will also be investigated.

In the subpopulation who also receive intracoronary imaging examinations, intracoronary imaging modalities will be used to refine the inner and outer vessel contours, improve the accuracy of plaque composition characterization, and aid in the discovery of novel high-risk plaque features by coronary CTA.

Questions about this trial

What is this clinical trial studying?

An observational study of Coronary Arterial Disease (CAD) and Coronary Arteriosclerosis, run by Ruijin Hospital at 2 sites in China.

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 3 inclusion and 10 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: looking for participants now, as of the sponsor's last update on 27 Jan 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 China. 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?

Contact Xiaoqun Wang (+86 21 64370045 671605, wangxq@shsmu.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Changes in total atheroma volume (TAV) (time frame: 24 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 27 Jan 2025; AzTrials last refreshed its copy on 8 Nov 2026.
