ABSTRACT: Carotid artery atherosclerosis (CAA) is one of the major high-risk
mechanisms of stroke. Relationship between IMT, carotid plaque echogenicity and
carotid stenosis assessed by ultrasound has not been systemically studied,
especially in subjects with mild to moderate carotid stenosis. In this study we
measured these 3 different ultrasound-derived quantitative traits concurrently
in the community population of southern China and compared their associations.
We found that IMTmean in the non-stenosis group (0%), mean of the P P mean in the no-plaque group, hyperechoic group
and hypoechoic group were 0.75 ± 0.13 mm, 0.87 ± 0.17 mm, 0.84 ± 0.15 mm
respectively. IMTmean of the hyperechoic group and the hypoechoic
group was higher than that of the no-plaque group (P mean of the hypoechoic group was lower
than that of the hyperechoic group, though with no statistic significance (P = 0.58). The proportion of hyperechoic
or hypoechoic plaque in the P P
