About this study

Official title: A Multi-center Prospective Cohort Study on the Evaluation of Vulnerability of Carotid Artery Plaques and Prediction of Cardio-Cerebrovascular Event Risk Using Ultrasonic Imaging

This study included patients with carotid artery atherosclerotic plaques to conduct multimodal ultrasound examinations, aiming to establish a plaque vulnerability assessment model based on ultrasonic imaging indicators, clinical history, and laboratory indicators. Based on the occurrence of cardiovascular and cerebrovascular events during the 3-year follow-up period, the correlation between the vulnerability of carotid plaques and the occurrence of cardiovascular and cerebrovascular events was explored. Furthermore, a cardiovascular and cerebrovascular risk prediction model for patients with plaques was established by combining multi-dimensional data indicators such as patients\' clinical data and ultrasonic multimodal imaging data, forming a risk warning tool suitable for clinical use and providing a reference for risk management in patients with carotid artery plaques.

Research Objectives:

  1. To establish a plaque vulnerability assessment model based on ultrasonic imaging indicators of plaques, clinical indicators of patients, and laboratory indicators.
  2. To establish a cardiovascular and cerebrovascular risk prediction model for patients with carotid plaques by combining clinical indicators of patients and ultrasonic multimodal imaging data.
  3. To screen ultrasonic imaging indicators for predicting cardiovascular and cerebrovascular events.
Read the detailed description

This study is a prospective multi-center cohort study that aims to collect 600 patients with carotid artery plaques (including over 66,000 multimodal ultrasound image data), with patients coming from five participating centers. Starting from the collection of cases, the follow-up period is 36 months, during which the occurrence of cardiovascular and cerebrovascular events in patients will be observed. The relationship between multimodal ultrasonic imaging indicators, the vulnerability of carotid plaques, and cardiovascular and cerebrovascular events will be explored. Based on this, a cardiovascular and cerebrovascular risk prediction model for patients with carotid artery plaques will be established, forming a risk warning tool suitable for clinical use.

Inclusion criteria:

  1. Patients who fully understand the purpose and significance of this experiment, voluntarily participate, and voluntarily sign the informed consent form;
  2. Patients over 40 years old;
  3. Patients with carotid plaque thickness ≥ 1.5 mm on conventional ultrasound, undergoing routine duplex ultrasound, contrast-enhanced ultrasound, ultrasound elastography, and three-dimensional ultrasound imaging.

Exclusion criteria:

  1. Patients with severe cardiopulmonary insufficiency; allergy to sulfur hexafluoride; pregnant or lactating women; those with advanced tumors;
  2. Poor quality of ultrasound images;
  3. Patients who have previously undergone carotid artery stenting or endarterectomy on the same side as the carotid plaque.

The study aims to complete the establishment of an imaging database for 600 patients undergoing ultrasound examinations for carotid artery plaques, follow them up for 36 months, and record whether cardiovascular and cerebrovascular diseases occur.

Study groups in NCT06473272
Study groupRoleWhat they receive
Symptomatic groupThe symptomatic group consisted of patients who were diagnosed with their first ipsilateral ischemic lesions in the carotid territory (anterior circulation) based on head computed tomography (CT) or magnetic resonance imaging (MRI) conducted within the previous 8 weeks.
Receives: Other: Cardiovascular and cerebrovascular diseases
Asymptomatic groupThe asymptomatic group included patients who showed no intracranial ischemic lesions on head CT/MRI images and exhibited no neurological symptoms.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. IPN semi-quantitative grading

    Grade 0: no microbubbles seen within the plaque; Grade 1: microbubbles limited to the plaque shoulder or adventitial surface; Grade 2: microbubbles visible at the thickest part of the plaque, the intimal surface, or extensive enhancement within the plaque

    Measured: 36 months

Secondary outcomes (3)
  1. Plaque volume (mm^3)

    using the software package provided with the ultrasound machine or post-processing software

    Measured: 36 months

  2. Average shear wave velocity

    After obtaining a stable grayscale image, select the shear wave elastography (SWE) mode and adjust the region of interest (ROI) to include the entire plaque. During the examination, ensure that the probe only has minimal contact with the skin to minimize compression artifacts. Freeze the image after stabilization, acquire the elastography image, and use the tracking tool to accurately outline the plaque boundary to obtain the average shear wave velocity (SWV).

    Measured: 36 months

  3. Ulceration and low-echo regions (if present)

    The largest area of surface ulceration and low-echo regions within the plaque

    Measured: 36 months

Questions about this trial

What is this clinical trial studying?

An observational study of Carotid Plaque and Ischemic Stroke, run by Shanghai General Hospital, Shanghai Jiao Tong University School of Medicine at 1 site 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 3 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 6 Dec 2024. 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 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 Rong Wu, Dr (+021-18917683516, wurong7111@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

IPN semi-quantitative grading (time frame: 36 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 6 Dec 2024.
