NCT03466255

Brief Summary

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.

Outcome Measures

Primary Outcomes (4)

  • Maximum Plaque Height (physiological parameter)

    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)

    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)

    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 of contrast entering the plaque will be assessed to see if it correlates to severity of angiographic CAD, using GE EchoPAC software.

    4 years
