Background: According to the current guidelines the visualization of atherosclerotic plaques in the carotid arteries is the only option that carotid ultrasound provides for the assessment of cardiovascular risk (CVR). The direction devoted to the development and implementation of markers based on the quantification of atheroma, is promising. The aim of the study was to evaluate the prognostic value of various carotid ultrasound parameters in patients at high and very high CVR.
Methods: Patients at high and very high CVR were included. All patients underwent carotid ultrasound. We evaluated carotid intima-media thickness (cIMT), carotid plaque, carotid plaque score (cPS) and carotid total plaque area (cTPA). The combined endpoint was cardiovascular death, non-fatal myocardial infarction or unstable angina, non-fatal stroke and coronary revascularization.
Results: The study included 100 patients. The duration of the follow-up period was 24.4 (14.1-34.3) months. Endpoint events occurred in 34.0% patients. cIMT and cPS were not significantly associated with the risk of cardiovascular events. The presence of carotid plaque in accordance with Cox regression after adjusting for possible confounders was associated with an increase in the relative risk of cardiovascular events by 10.5 times (95% CI 1.27-86.5; p = 0.008). CTPA ≥69 mm according to adjusted analysis was associated with an increase in the risk of cardiovascular events by 5.86 times (95% CI 2.09-16.4; p = 0.001).
Conclusion: In patients at high and very high CVR among carotid atherosclerosis markers only carotid plaque and cTPA had an independent predictive value regarding the development of adverse cardiovascular events.

Background/purpose: Although metabolic dysfunction-associated steatotic liver disease (MASLD) has been proposed to replace the diagnosis of non-alcoholic fatty liver disease (NAFLD) with new diagnostic criteria since 2023, the genetic predisposition of MASLD remains to be explored.
Methods: Participants with data of genome-wide association studies (GWAS) in the Taiwan Biobank database were collected. Patients with missing data, positive for HBsAg, anti-HCV, and alcohol drinking history were excluded.

Objective: Previous studies suggested that sudomotor dysfunction is closely related to multiple diabetic microvascular complications. We aimed to investigate the association between sudomotor dysfunction and subclinical carotid atherosclerosis (SCAS) in people with type 2 diabetes.
Methods: A total of 1788 participants were included in this cross-sectional study.
Introduction: The recently proposed cerebral small vessel disease (CSVD) score system may help to capture the overall burden of CSVD. This study aimed to investigate the associations between carotid artery ultrasound features and the burden score and cognitive performance of CSVD patients.
Methods: This is a cross-sectional analysis of an ongoing prospective study.

Women are disproportionately affected by chronic autoimmune diseases (AD) like systemic lupus erythematosus (SLE), scleroderma, rheumatoid arthritis (RA), and Sjögren's syndrome. Traditional evaluations often underestimate the associated cardiovascular disease (CVD) and stroke risk in women having AD. Vitamin D deficiency increases susceptibility to these conditions.
