“…Age, hypertension, smoking, diabetes, and atrial fibrillation are known as SCI risk factors. In addition, recent studies indicated carotid plaque and increased IMT are also risk factors (28,29). The results of our study support those findings and show that the carotid arteries can be a window into atherosclerosis in the cerebrovascular system.…”

“…The association of LIs with carotid plaque is in agreement with the literature. 18,19 Previous publications also described an association among carotid stenosis, number or characteristics of carotid plaque, and WMHV. 7,9,20 In the present dataset, we observed an association of carotid plaque with WMHV and L-WMHV, even after accounting for vascular risk factors.…”

Objective: Our aim was to investigate the relationship of carotid structure and function with MRI markers of cerebral ischemic small-vessel disease.Methods: The study comprised 1,800 participants (aged 72.5 6 4.1 years, 59.4% women) from the 3C-Dijon Study, a population-based, prospective cohort study, who had undergone quantitative brain MRI and carotid ultrasound. We used multivariable logistic and linear regression adjusted for age, sex, and vascular risk factors.Results: Presence of carotid plaque and increasing carotid lumen diameter (but not common carotid artery intima-media thickness) were associated with higher prevalence of lacunar infarcts: odds ratio ( Conclusions: In addition to and independently of carotid plaque, increasing carotid lumen diameter and markers of carotid stiffness were associated with increasing prevalence of lacunar infarcts and increasing WMHV, respectively.

Vascular lesions, including MRI-defined brain infarcts (BIs) and white matter hyperintensities (WMH), are frequently observed in older community-dwelling individuals. The prevalence of BIs ranges between 8% and 28% 2,3

“…Moreover, cross-sectional associations were found in several studies between CCA intima-media thickness (IMT) and presence of carotid plaques and strokes caused by large vessel pathology [10][11][12]. The IMT comprises endothelial cells, connective tissue, smooth muscle cells, and lipid deposition [13].…”

The purpose of this study was to determine if carotid artery wall thickness (CAWT) studied by using multi-detector-row CT angiography (MDCTA) can be considered an effective parameter predictive of increased risk of stroke. A total of 217 patients were retrospectively studied by using MDCTA. In all patients CAWT was measured with an internal digital caliper. Continuous data were described as the mean value +/- standard deviation (SD), and they were compared with Student's t-test. Scatter plots to determine interobserver agreement were performed, and correlation coefficient was calculated with Pearson statistics. A P value <0.05 was considered to mean statistical significance. Measurements of the distal common CAWT ranged from 0.5 to 1.6 mm. In the patient group without stroke, average CAWT was 0.82 mm (0.22 SD), whereas in patient group with stroke it was 1.096 mm (0.21 SD). CAWT in patients without stroke showed statistical difference (P < 0.0001) when compared to patients with stroke. By using a threshold of 1 mm, an important statistical association between thick CAWT and stroke was found (P < 0.0001). In fact, patients with > or = 1 mm CAWT had stroke with an odds ratio of 8.16 when compared with patients with <1 mm CAWT. Resulting data suggested that an increased CAWT is an indicator for risk of stroke. This parameter should be considered in addition to other well-known risk factors such as diabetes, hypertension, smoking, and dyslipidemia.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
