AIMS: To determine the extent to which the adverse effects of blood pressure (BP) are mediated by pulsatile haemodynamic changes across the normotensive as compared with the hypertensive adult brachial BP range, and whether aortic rather than brachial pulsatile changes best index these effects. METHODS: In 1307 community participants, the contribution of pulsatile haemodynamics (applanation tonometry and SphygmoCor software) to variations in left ventricular mass index (LVMI) (echocardiography) (n = 920), carotid intima-media thickness (IMT) (n = 712) and estimated glomerular filtration rate (eGFR) (n = 1164) were assessed...

Background: Previously, we reported on vascular cognitive impairment (VCI) templates, consisting of patients with VCI associated with carotid stenosis (>60%) using a quantitative electroencephalographic (EEG) technique called neuronal activity topography (NAT). Here using the VCI templates, we investigated the hypothesis that internal carotid artery-intima-media thickness (ICA-IMT) is associated with EEG spectrum intensity (sNAT) and spectrum steepness (vNAT). Methods: A total of 221 community-dwelling elderly subjects were recruited...

BACKGROUND: The ankle-brachial index (ABI) is inadequate to detect early-stage atherosclerotic disease, when interventions to prevent functional decline may be the most effective. We determined associations of femoral artery atherosclerosis with physical functioning, across the spectrum of the ABI, and within the normal ABI range. METHODS AND RESULTS: In 2007-2011, 1103 multiethnic men and women participated in the San Diego Population Study, and completed all components of the summary performance score...

Objective Arterial stiffening is an early marker of atherosclerosis that has a prognostic value for cardiovascular morbidity and mortality. Although many markers of arterial hardening have been proposed, the search is on for newer, more user-friendly and reliable surrogates. One such potential candidate has emerged from cardiology, the speckle-tracking technique. The aim of this study was to evaluate the feasibility of the two-dimensional speckle tracking for the evaluation of arterial wall stiffness in comparison with standard stiffness parameters...

South Africans are at high risk for developing cardiovascular disease. Endothelin-1 is known for its vasoconstrictive properties and its ability to contribute to vascular structural changes. In this study we investigated the association of change in endothelin-1 levels and change in markers implicated in vascular remodelling after 3 years. Serum endothelin-1 levels and markers of vascular remodelling such as carotid intima-media thickness, carotid cross-sectional wall area (CSWA) and arterial compliance were measured...

Previous studies have supported the theory that there is a positive association between ferritin and carotid atherosclerosis in Western people. Diet plays an important role in determining serum ferritin concentration. Asian dietary patterns are different from Western dietary patterns, implying that there may be a difference in the association of ferritin with carotid atherosclerosis between Asian and Western people. However, few studies focus on the association between ferritin and carotid atherosclerosis among Asians...

Atherosclerosis is frequently present in patients with chronic kidney disease (CKD) treated with dialysis. We evaluated the association between residual renal function (RRF), phosphate level, inflammation and other risk factors in carotid modeling as a marker of early atherosclerosis in peritoneal dialysis (PD) compared with hemodialysis (HD) patients. We studied 39 stable PD and 53 HD patients on renal replacement therapy (RRT) for 3 to 36 months duration. B-mode ultrasonography was used to determine carotid artery intima media thickness (CIMT)...

PURPOSE: Neointimal hyperplasia (NH) is considered to be one of the main causes of vascular access occlusion in patients receiving hemodialysis. Endothelial injury and TGF-β-mediated proliferation of vascular smooth muscle cells (VSMCs) induce NH. Endothelial microparticles (EMPs) are also increased by endothelial injury. We aimed to investigate the effects of EMPs and TGF-β expression on VSMC proliferation and their contributions to NH formation in an ex vivo model. METHODS: EMPs were collected from the culture media of human umbilical vein endothelial cells treated with indoxyl sulfate (IS, 250 µg/mL) after ultracentrifugation at 100,000 × g...

Uveitis is a chronic inflammatory disease. Chronic inflammation has been shown to have a role in pathogenesis of atherosclerosis. Atherosclerosis is the most important risk factor of cardiovascular diseases and is shown to start as early as childhood. In this study, we investigated the presence of subclinical atherosclerosis in children with uveitis. Seventy five patients who were diagnosed as having uveitis in ophthalmology and pediatric rheumatology clinics were included in the study. Patients with hypertension, obesity, dyslipidemia, diabetes, and with history of early cardiovascular disease were excluded...

According to international guidelines, women with obesity without other comorbidities can safely use any hormonal contraceptive (HC). However, limited information is available about contraceptive safety for women with obesity since obesity is an exclusion criterion of most contraceptive clinical trials. As such little is known about the possible risks of HC exposure for women with obesity without comorbidities. One way to assess possible long-term risks in this population, even prior to the development of any clinical disease, is to measure alterations in subclinical atherosclerosis markers...
