Carotid plaque fibrous and calcium-like tissues are correlated with increased CAD. Increased percent fat or percent calcium is associated with risk for CV events; however, a combination of plaque height, percent calcium, and/or percent fat increases risk for CV events. Incorporating ultrasound carotid plaque composition into screening practice may improve patient risk stratification for heart disease.

American Society of Echocardiography


In the assessment of asymptomatic atrisk patients, we suggest a stepwise approach to cardiovascular risk
stratification using plaque grading via a focused carotid vascular ultrasound and subsequent 2D or 3D plaque quantification
