AI Article Synopsis
- Carotid intima-media thickness (C-IMT) serves as a key measure for assessing early signs of atherosclerosis, while neck circumference (NC) is emerging as a relevant indicator of upper body fat related to cardiovascular disease risk.
- In a study involving participants from Shanghai, those with a higher neck circumference showed a significantly increased likelihood of developing carotid plaque and elevated C-IMT over a mean follow-up period of 2.1 years.
- The findings suggest a strong association between higher neck circumference and an increased risk of both carotid plaque formation and elevated C-IMT, highlighting the importance of monitoring neck circumference for cardiovascular health assessment.
Article Abstract
Background And Aims: Carotid intima-media thickness (C-IMT) is an important index for evaluating subclinical atherosclerosis. Neck circumference (NC), a new anthropometric index of the upper body fat, is closely related to cardiovascular disease (CVD) and CVD risk factors. This study investigated the relationship between NC, C-IMT, and carotid plaque in a community-based cohort.
Methods And Results: Participants recruited from Shanghai communities were followed up for 1.1-2.9 years. All participants underwent anthropometric and biochemical measurements. Elevated NC was defined as NC ≥ 38.5 cm and NC ≥ 34.5 cm in men and women, respectively. Elevated C-IMT, determined by ultrasound, was defined as a level higher than the 75th percentile in the study population (>0.75 mm). In total, 1189 participants without carotid plaque at baseline were included, with an average age of 59.6 ± 7.3 years. After a mean follow-up of 2.1 ± 0.2 years, 203 participants developed carotid plaques. After adjusting for various atherosclerosis risk factors, the logistic regression showed that the higher NC group had a significantly greater risk of developing carotid plaque than the lower NC group (odds ratio [OR], 1.55; 95% confidence interval [CI], 1.12-2.14; P = 0.008). Of those without carotid plaque at follow-up, 495 participants developed elevated C-IMT. Compared to the lower NC group, the higher NC group had a significantly increased risk of elevated C-IMT (OR, 1.49; 95% CI, 1.14-1.95; P = 0.003).
Conclusion: Higher NC was significantly positively correlated with the risk of carotid plaque and elevated C-IMT.

Purpose: To describe a case of short common trunk of the occipital artery (OA) and ascending pharyngeal artery (APA) arising from the internal carotid artery (ICA).
Methods: A 36-year-old woman with a history of surgical resection of a right lateral ventricular meningioma and atheromatous plaque of the right ICA underwent cranial magnetic resonance (MR) imaging and MR angiography of the head and neck region with a 3-Tesla scanner.
Results: MR angiography of the neck region showed a small atheromatous plaque at the origin of the right ICA and an anomalous artery arising from the posteromedial aspect of the right ICA at the distal end of the carotid bulb.

Objective: To develop a deep learning (DL) model for carotid plaque detection based on CTA images and evaluate the clinical application feasibility and value of the model.
Methods: We retrospectively collected data from patients with carotid atherosclerotic plaques who underwent continuous CTA examinations of the head and neck at a tertiary hospital from October 2020 to October 2022. The model combined ResUNet with the Pyramid Scene Parsing Network (PSPNet) to enhance plaque segmentation.

Department of Endocrinology, The Second Affiliated Hospital of Anhui Medical University, Hefei Anhui, 230601, China.
Background: The triglyceride-glucose (TyG) index has been identified as an alternative biomarker for insulin resistance (IR), while residual cholesterol (RC) is a simple, cost-effective, and easily detectable lipid metabolite. However, the associations of these two markers with carotid plaque presence remain unclear. Thus, this study aimed to explore their associations with carotid plaque presence.

Background: Complement activation may promote atherosclerosis. Yet, data on the to which extent complement, and more specifically the alternative complement pathway, is activated in patients with carotid atherosclerosis and related to adverse outcome in these patients, are scarce.
Methods And Results: We measured, by ELISA, plasma levels of factor D, properdin, C3bBbP (C3 convertase), and factor H in patients with advanced carotid atherosclerosis in a (n=324) and in a (n=206) cohort in relation to adverse outcome (mean follow-up 7.
