BACKGROUND AND AIMS: Exposure to psychosocial stress is a risk factor for cardiovascular disorders. Because the glucagon-like peptide-1 (GLP-1) receptor (GLP-1R) agonist prevents cardiovascular injury, we investigated the beneficial effects and mechanism of the GLP-1 analogue exenatide on stress-related vascular senescence and atherosclerosis in apolipoprotein E-deficient (ApoE(-/-)) mice fed a high-fat (HF) diet. METHODS: ApoE(-/-) mice fed the HF diet were assigned to non-stressed and immobilized-stress groups for 12 weeks...

Cardiovascular diseases (CVD) are the most frequent cause of death in developed countries. Their prevalence is higher in several chronic inflammatory conditions. This is likely due to the substantial contribution of the inflammatory status of the patients to the development and stability of atherosclerotic plaques. Recent evidence suggests that interleukin (IL)-32 may be involved in the conditions that contribute to CVD. IL-32 not only modulates important inflammatory pathways known to contribute to the pathogenesis of both inflammatory diseases and atherosclerosis, including tumor necrosis factor (TNF)α, IL-6 or IL-1β, but it has been also suggested to modulate endothelial cell function and the serum concentration of high-density lipoprotein (HDL)...

BACKGROUND AND AIMS: After assessing the risk for cardiovascular disease (CVD) based on traditional risk factors, decisions concerning lipid lowering therapy might remain uncertain. To investigate whether lipoprotein subfraction levels could aid these decisions, we assessed the association between lipoprotein subfractions and CVD, after adjustment for traditional risk factors including standard lipids. METHODS: Using a case-cohort design, participants were randomly drawn from the Malmö Prevention Project (MPP), a population-based prospective study of 18,240 participants, and supplemented with additional incident CVD events (5764 participants, 1784 CVD events)...

BACKGROUND AND AIMS: Previous studies showed an independent association of low ankle-brachial index (ABI) with cognitive impairment. However, the association between low ABI and cognition in the presence of both cerebrovascular disease (CeVD) and neurodegeneration is lacking. We aimed at investigating a) the association of low ABI with markers of CeVD and cortical thickness, and b) whether the association of low ABI with cognition is influenced by these markers. METHODS: Data was drawn from the Epidemiology of Dementia In Singapore (EDIS) study where all participants (n = 832) underwent neuropsychological tests and 3T brain magnetic resonance imaging (MRI) to assess CeVD markers as well as cortical thicknesses...

BACKGROUND AND AIMS: Recent epidemiological studies have showed that excessive intake of trans fatty acids (TFA) can be a residual risk for the development of coronary artery disease (CAD) even under medical management, including statins. This study aimed at investigating the association between lipid profile, including serum TFA concentration, and plaque vulnerability using optical coherence tomography (OCT). METHODS: The level of serum elaidic acid, a major TFA component, was measured using gas chromatography in 161 consecutively enrolled patients with CAD under guideline-directed risk factor management...

BACKGROUND AND AIMS: Physical inactivity is linked to low-grade inflammation, endothelial dysfunction and cardiovascular disease. We aimed to determine effects of active commuting and leisure time exercise on markers of low-grade inflammation and endothelial function in overweight and obese women and men. METHODS: We randomized 130 younger (20-45 years), physically inactive, healthy, overweight and obese (BMI: 25-35 kg/m(2)) women and men recruited from the Copenhagen area, Denmark, to either 6 months of habitual lifestyle (CON, n = 18), active commuting (BIKE, n = 35), or leisure time exercise of moderate (MOD, ∼50% VO2peak, n = 39) or vigorous intensity (VIG, ∼70% VO2peak, n = 38)...

BACKGROUND AND AIMS: Glucagon-like peptide-1 (GLP-1) is thought to inhibit development of aortic atherosclerosis and plaque formation. However, whether GLP-1 stabilizes fully developed atherosclerotic plaque or alters the complicated plaque composition remains unclarified. METHODS: Ten Watanabe heritable hyperlipidemic (WHHL) rabbits were divided into GLP-1 receptor agonist treatment group and control group. After confirmation of atherosclerotic plaques in brachiocephalic arteries by iMap intravascular ultrasound (iMAP-IVUS), GLP-1 receptor agonist lixisenatide was administered to WHHL rabbits at 30 nmoL/kg/day for 12 weeks by osmotic pump...

BACKGROUND AND AIMS: Aortic atherosclerosis is an aggregate marker of vascular risk factor exposure and has been associated with intracranial atherosclerosis and stroke. We hypothesized that atherosclerosis of the descending aorta (DAo) could be a risk marker for brain aging and injury. METHODS: We evaluated 1527 participants (mean age 59.9 years, 53.5% women) in the Framingham Offspring cohort who underwent both aortic and brain MRI. Participants were free of clinical stroke, dementia, or other neurological illness at the time of axial MRI of the thoracic and abdominal DAo and subsequent brain MRI...

BACKGROUND AND AIMS: Limited evidence is available on the association between markers of arterial stiffness and the prevalence of atrial fibrillation among Asian populations. Therefore, we examined those associations in the Japanese population. METHODS: We conducted a cross-sectional population-based study of 4264 men and women aged 40-79 years. The augmentation index (AI), a marker of arterial stiffness, was calculated as the ratio of central pulse pressure/brachial pulse pressure, where the AI and central aortic pressure were measured by an automated tonometer: the HEM-9000AI device (Omron Healthcare co...

BACKGROUND AND AIMS: High-density lipoprotein cholesterol (HDL-C), an established risk marker for atherosclerotic cardiovascular disease (CVD), has been shown to be inversely and independently associated with incident hypertension. Paraoxonase-1 (PON-1) is an HDL-bound esterase enzyme associated with CVD, but its relationship with incident hypertension has not been previously investigated. We aimed at evaluating the prospective association between PON-1 and hypertension risk. METHODS: PON-1 arylesterase activity was measured in serum at baseline in 3988 participants without pre-existing hypertension in the Prevention of Renal and Vascular End-stage Disease (PREVEND) prospective population-based study...
