Early Detection of Cardiovascular Disease (VIBE)

June 8, 2022 updated by: Dr. Amer Johri

Vascular Imaging as a Barometer for the Early Detection of Cardiovascular Disease

The investigators plan to evaluate the correlation between carotid plaque enhancement on Contrast-enhanced ultrasound (CEUS), significant coronary artery disease (CAD), and cardiovascular (CV) outcomes in a systematic manner. The investigators hypothesize that increased levels of CEUS-detected vulnerable carotid plaque will be predictive of CV risk determined by angiography and future cardiovascular events.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Study Design: The investigators will conduct a prospective, single-center, observational study at the Cardiovascular Imaging Network at Queen's (CINQ, www.CINQLab.com). This facility allows a CEUS protocol to be conducted on the same day as the angiogram. It is anticipated that 100 participants can be recruited per month with a total target enrolment of up to 1000 participants.

Objectives

  1. To determine the test characteristics (sensitivity, specificity, negative/positive predictive values) of carotid plaque by CEUS (Definity(R)) for predicting significant CAD (≥50% stenosis) in participants referred for angiography
  2. To determine the test characteristics (sensitivity, specificity, predictive values) of carotid plaque by CEUS for predicting future CV events, such as death, stroke, myocardial infarction, and cardiovascular interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Subjects referred for outpatient coronary angiography will be screened for inclusion.

Description

Inclusion criteria:

  1. >18 years of age
  2. Outpatients referred for clinically indicated angiography for assessment of CAD
  3. Low - Intermediate Framingham risk (<20%)
  4. Absence of clinical contraindication to angiography
  5. Able and willing to give informed consent

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Maximum Plaque Height (physiological parameter)
Time Frame: 4 years
Caliper measurement of carotid plaque height on ultrasound images, using GE EchoPAC software. The maximum height of either side will be used to correlate to severity of angiographic CAD and neovascularization score.
4 years
Total Plaque Area (physiological parameter)
Time Frame: 4 years
Area measurement of carotid plaque on ultrasound images (right + left side), using GE EchoPAC software. The total plaque area will be used to correlate to severity of angiographic CAD and neovascularization score.
4 years
Neovascularization (contrast enhancement intensity) (physiological parameter)
Time Frame: 4 years
A neovascularization score will be used to grade the "activity" of the carotid plaque per participants and be correlated to angiographic CAD, visualized and manually counted using GE EchoPAC software.
4 years
Contrast wash-in time (physiological parameter)
Time Frame: 4 years
Time of contrast entering the plaque will be assessed to see if it correlates to severity of angiographic CAD, using GE EchoPAC software.
4 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Participants CV outcome follow-up (data linkage through the Institute for Clinical Evaluative Sciences: ICES)
Time Frame: 5 years
Participants will be followed for major adverse cardiac event over 5 years. Number of events will be correlated to carotid plaque measurements.

Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
