Article Abstract
Background: This study aimed to examine whether baseline atherosclerosis was associated with subsequent short-term domain-specific cognitive decline.
Methods And Results: This research was based on the BRAVE (Beijing Research on Aging and Vessel) study, a population-based prospective cohort study of adults aged 40 to 80 years, free of dementia. At baseline (wave 1, 2019), cognitive assessments and atherosclerosis measures, including carotid intima-media thickness, carotid plaques, coronary artery calcification, and brachial-ankle pulse wave velocity were conducted. Cognitive function was reassessed in wave 2 (2022-2023) using linear mixed models for analysis. A total of 932 participants (63.7% women; mean age, 60.0±6.9 years) were included. Compared with the lowest tertile of carotid intima-media thickness, carotid plaques, and brachial-ankle pulse wave velocity, or a coronary artery calcification score=0, the highest tertile of carotid intima-media thickness (β=-0.065 SD/y [95% CI, -0.112 to -0.017]; =0.008), carotid plaques (β=-0.070 SD/y [95% CI, -0.130 to -0.011]; =0.021), and brachial-ankle pulse wave velocity (β=-0.057 SD/y [95% CI, -0.105 to -0.010]; =0.018), and a coronary artery calcification score≥400 (β=-0.081 SD/y [95% CI, -0.153 to -0.008]; =0.029) were significantly associated with a faster decline in semantic fluency after multivariable adjustment. Moreover, greater carotid intima-media thickness, coronary artery calcification, and brachial-ankle pulse wave velocity were significantly associated with a faster decline in global cognition.
Conclusions: More significant atherosclerosis was associated with faster semantic fluency and global cognition declines.

Cardiovascular assessments in children and adolescents with hypertension are essential for detecting early signs of organ damage and guiding timely interventions. The pathophysiology of pediatric hypertension involves a complex interplay of arterial stiffness, endothelial dysfunction, metabolic disturbances, activation of the renin-angiotensin-aldosterone system, and immune dysregulation. These mechanisms collectively contribute to target organ damage, particularly in the cardiovascular system.

Objectives: To evaluate the predictive role of carotid stiffening, quantified using ultrafast pulse wave velocity (ufPWV), for assessing cardiovascular risk in young populations with no or elevated cardiovascular risk factors (CVRFs).
Materials And Methods: This study enrolled 180 young, apparently healthy individuals who underwent ufPWV measurements. They were classified into three groups: the CVRF-free group (n = 60), comprising current non-smokers with untreated blood pressure < 140/90 mmHg, fasting blood glucose (FBG) < 7.

Background Chronic kidney disease is a major global health problem, significantly increasing the risk of cardiovascular complications compared to the general population. This study aimed to evaluate vascular aging in patients with end-stage renal disease treated with hemodialysis or peritoneal dialysis by analyzing clinical and laboratory parameters and carotid intima-media thickness (CIMT), with the goal of identifying predictors of carotid disease and comparing the prevalence between groups. Methods We conducted a retrospective cohort study that included 59 subjects with end-stage renal disease who were treated with renal replacement therapy: peritoneal dialysis (29 subjects) and hemodialysis (30 subjects).

Background: Premature atherosclerosis has been observed among people with HIV (PWH) with high risk of cerebrovascular disease. The aim of this study was to evaluate premature atherosclerosis in young PWH with and without ischemic stroke.
Methods: We conducted a prospective case-control study at the University Teaching Hospital in Lusaka, Zambia between March 2022 and October 2024, comparing young PWH with non-cardioembolic ischemic stroke (cases) with PWH without a history of stroke (controls) matched (1:2) for age, sex and race.
Rotating shift work, with night shift work, affects cardiovascular risk factors: a 6-year follow-up study in the insulation industry.

Objectives: To assess absolute levels and longitudinal changes in cardiovascular disease (CVD) risk factors over 6 years among rotating shift workers with night shift work and day workers in industry.
Methods: We studied three groups, 32 night shift workers in Plant A with a high night load, 23 in Plant B with a low night load and 25 day workers during a 6-year follow-up (FU). We collected demographics by questionnaire, measured blood pressure, resting heart rate, carotid intima-media thickness (cIMT), carotid to femoral pulse wave velocity (cfPWV) and maximal oxygen uptake (V̇O).
