VIBE Program

Vascular Imaging as a Barometer for Early Detection of Heart Disease (VIBE Program)

Plaque is composed of well-calcified, hard, stable components which are bright white on echo, and/or soft, vulnerable components which appear black/gray. The goal of this program is to validate the concept that vascular ultrasound can be used as an early warning “barometer” for vulnerable plaque (unstable plaque that can cause strokes and heart attacks).

Two main projects: Project A – Hardening of the artery (Atherosis/Plaque) and Project B – Stiffening of the artery (Sclerosis).

Given Ontario’s skyrocketing rate of cardiac risk factors, we have a tremendous need for experts adept at technological solutions to detect disease early and accurately.
