Abstract

Background and Purposes: This study aimed to identify clinical and ultrasound imaging predictors of progression of carotid luminal narrowing in subjects with asymptomatic moderate internal carotid artery (ICA) stenosis. Methods: A total of 571 subjects with asymptomatic moderate (50-69%) ICA stenoses were enrolled. They underwent ultrasound examination at baseline and after 12 months. Demographics, vascular risk factors, medications, plaque characteristics (surface and echogenicity) and common carotid intima-media thickness (IMT) were collected. At the follow-up examination, any change of ICA stenosis was graded in three categories (i) ≥70% to near occlusion, (ii) near occlusion, and (iii) occlusion. Progression of stenosis was defined as an increase in the stenosis degree by at least one category from baseline to follow-up. Results: At 12 months, progression occurred in 142 subjects (prevalence rate 25%). At the multivariable logistic model, pathological IMT values (considered as binary variable: normal: ≤1 mm vs. pathologic: >1 mm) significantly predicted the risk for plaque progression after adjusting the model for possible confounders (OR 2.28, 95% CI 1.18-4.43, P = .014, multivariable logistic model). Conclusions: Our results confirm the role of carotid wall thickening as a marker of atherosclerosis. Carotid IMT measurement should be considered to implement risk stratification in patients with asymptomatic carotid disease.
