BACKGROUND AND OBJECTIVE: During recent years, some persistent organic pollutants (POPs) have been linked to atherosclerosis. One group of POPs, the poly- and perfluoroalkyl substances (PFASs) have not been investigated with regard to atherosclerotic plaques. METHODS: Carotid artery atherosclerosis was assessed by ultrasound in 1016 subjects aged 70 years in the Prospective Investigation of the Vasculature in Uppsala Seniors (PIVUS) study. Eight PFASs were detected in >75% of participants' plasma by ultra-performance liquid chromatography coupled to tandem mass spectrometry (UPLC-MS/MS)...

Cardiovascular diseases are the leading cause of mortality among women in several countries. Early detection of subclinical atherosclerosis (SA) could enable the adoption of preventive measures to avoid cardiovascular events. This study aimed to determine the prevalence of SA in Brazilian asymptomatic postmenopausal women in Framingham Risk Score (FRS) low and intermediate groups. Computed tomography (CT) and ultrasound (US) scans were performed in 138 asymptomatic postmenopausal women (56.1 ± 4.9 years of age) to survey for coronary artery and aortic calcification (CT scan) and assess carotid intima-media thickness (CIMT) and identify carotid plaques (US)...

BACKGROUND: Functional magnetic resonance (MR) imaging of atheroma using contrast media enables assessment of the systemic severity of atherosclerosis in different arterial beds. Whether black-blood imaging has similar ability remains widely unexplored. In this study, we evaluate whether black-blood imaging can differentiate carotid plaques of patients with and without coronary artery disease (CAD) in terms of morphological and biomechanical features of plaque vulnerability, thereby allowing assessment of the systemic severity nature of atherosclerosis in different arterial beds...

Carotid artery atherosclerosis is a main cause of stroke. Understanding atherosclerosis biology is critical in the development of targeted prevention and treatment strategies. Consequently, there is demand for advanced tools investigating atheroma pathology. We consider hybrid optoacoustic and multiphoton microscopy for the integrated and complementary interrogation of plaque tissue constituents and their mutual interactions. Herein, we visualize human carotid plaque using a hybrid multimodal imaging system that combines optical resolution optoacoustic (photoacoustic) microscopy, second and third harmonic generation microscopy, and two-photon excitation fluorescence microscopy...

Vascular smooth muscle cell (SMC) migration is an essential step involved in neointimal formation in restenosis and atherosclerosis. Lysophosphatidic acid (LPA) is a bioactive component of oxidized low density lipoprotein and is produced by activated platelets, implying that LPA influences vascular remodeling. Our previous study revealed that matricellular protein CCN1, a prominent extracellular matrix (ECM) protein, mediates LPA-induced SMC migration in vitro. Here we examined the role of CCN1 in LPA-induced neointimal formation...

BACKGROUND: Epidemiological studies demonstrate an inverse association between serum magnesium and incidence of cardiovascular disease. Diuretics commonly cause hypomagneseamia. METHOD: We evaluated effects of magnesium supplementation on blood pressure (BP) and vascular function in thiazide-treated hypertensive women in a randomized, double-blind, clinical trial. Hypertensive women (40-65 years) on hydrochlorothiazide and mean 24-h BP at least 130/80 mmHg were divided into placebo and supplementation (magnesium chelate 600 mg/day) groups...

BACKGROUND: Epidemiological studies have shown an inverse relationship between vitamin D levels and cardiovascular diseases. However, this does not infer a causal relationship between the two. Chronic kidney disease (CKD) patients have a high prevalence of vitamin D deficiency and carotid atherosclerosis. Therefore, in this study we have aimed to determine the association between serum 25-hydroxyvitamin D levels and carotid atherosclerosis in the CKD population. METHODS: 100 CKD stage 3-4 patients were included in the study...

Resistant hypertension is defined as a blood pressure above 140/90 mmHg despite adherence to a combination of at least three optimally dosed antihypertensive medications, one of which is a diuretic. Chronic kidney disease (CKD) is one of the more common patient comorbidities associated with resistant hypertension. Recommended low-salt diet and triple antihypertensive drug regimens that include a diuretic, should be complemented by the sequential addition of other antihypertensive drugs. CKD is associated with premature vascular ageing, characterized by accelerated arteriosclerosis or atherosclerosis and endothelial dysfunction...

OBJECTIVE: Though both carotid bulb and aortic arch are known to play important roles in regulation of blood pressure through modulation in baroreflex function, few studies have investigated the association of carotid bulb atherosclerosis and large arterial stiffness and orthostatic blood pressure change. DESIGN AND METHOD: Patients with metabolic disorder such as hypertension, dyslipidemia and diabetes mellitus underwent measurement of segment-specific carotid intima-media thickness (IMT) (as an index of atherosclerosis of carotid bulb), cardio-ankle vascular index (CAVI) (as an index for large arterial stiffness), heart rate variability (HRV) (as an index of baroreflex function) and sit-to-stand orthostatic blood pressure change (as a simple method for detecting orthostatic hypotension)...

Aging causes progressive changes in the structure and function of the large arteries that adversely impact the heart and vital organs. Vascular aging is a major independent risk factor for the development of cardiovascular diseases and events. Arterial stiffening is the dominant hemodynamic manifestation of vascular aging and a major independent predictor for incident hypertension. Arterial stiffening is therefore responsible for the very high residual lifetime risk for hypertension for middle-aged and elderly individuals...

Cardiovascular disease is the leading cause of morbidity and mortality in patients with chronic kidney disease (CKD). The carotid intima-media thickness (CIMT) and arterial stiffness are useful markers of subclinical atherosclerosis and significantly correlate with various metabolic risk factors. Chemerin is one of the adipokines that may represent a link between obesity and inflammation and may be a potential candidate playing a role in the pathogenesis of atherosclerosis and cardiovascular complications. Therefore, we studied the relationship of chemerin levels with atherosclerosis as measured by CIMT in diabetic CKD patients, either predialysis or on hemodialysis (HD)...

BACKGROUND AND AIMS: Monocytes are known to play a key role in the initiation and progression of atherosclerosis and contribute to plaque destabilization through the generation of signals that promote inflammation and neoangiogenesis. In humans, studies investigating the features of circulating monocytes in advanced atherosclerotic lesions are lacking. METHODS: Patients (mean age 69 years, 56% males) with intermediate asymptomatic carotid stenosis (40-70% in diameter) were evaluated for maximal stenosis in common carotid artery, carotid bulb and internal carotid artery, overall disease burden as estimated with total plaque area (TPA), greyscale and neovascularization in 244 advanced carotid plaques...
