简要总结
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.
详细描述
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
- 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
- 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.

结局指标
主要结局
Maximum Plaque Height (physiological parameter)
时间窗: 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.
Total Plaque Area (physiological parameter)
时间窗: 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.
Neovascularization (contrast enhancement intensity) (physiological parameter)
时间窗: 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.
Contrast wash-in time (physiological parameter)
时间窗: 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.
次要结局
- Participants CV outcome follow-up (data linkage through the Institute for Clinical Evaluative Sciences: ICES)(5 years)
