OBJECTIVE: To determine whether differences exist in valvular high density lipoprotein (HDL) content between non-stenotic and stenotic aortic valves, and whether HDL could retard valvular calcification locally. METHODS: Stenotic aortic valves were obtained from valve replacement surgery and non-stenotic control valves from cardiac transplantations or at autopsy. The valvular localization ...

OBJECTIVE: We have previously demonstrated that bindarit, a selective inhibitor of monocyte chemotactic proteins (MCPs), is effective in reducing neointimal formation in rodent models of vascular injury by reducing smooth muscle cell proliferation and migration and neointimal macrophage content, effects associated with the inhibition of MCP-1/CCL2 production. The aim of ...

Interruption of the aortic arch (IAA) is difficult to detect and diagnose in utero. However, prenatal diagnosis may be beneficial because IAA is rapidly fatal (median age, 10 d) if left uncorrected. Our objective was to review the direct and indirect echocardiographic markers associated with IAA, focusing on the importance ...

BACKGROUND:: Multiple sclerosis (MS) is an inflammatory disorder of the brain and spinal cord. Disability status and progression are associated with reduced physical activity (PA) and cardiovascular function. Lack of adequate PA combined with inflammation may create high susceptibility to subclinical atherosclerosis and vascular dysfunction. PURPOSE:: The purpose of this ...

Spinal cord injury leads to increased risk for cardiovascular disease and results in greater risk of death. Subclinical markers of atherosclerosis have been reported in carotid arteries of spinal cord-injured individuals (SCI), but the development of lower extremity peripheral arterial disease (PAD) has not been investigated in this population. The ...

Vascular access dysfunction continues to be a major cause of morbidity and mortality in the end-stage renal patient. Thrombosis is the primary cause of prosthetic arteriovenous access (ie, graft) failure caused by the progressive development of neointimal hyperplasia, which eventually leads to a stenosis, usually at the venous anastomosis. More ...

We have previously identified heavy snoring as an independent risk factor for carotid atherosclerosis. In order to explore the hypothesis that snoring-associated vibration of the carotid artery induces endothelial dysfunction (an established atherogenic precursor), we utilized an animal model to examine direct effects of peri-carotid tissue vibration on carotid artery ...

BACKGROUND:: Normovolemic hemodilution is known to inhibit hypoxic pulmonary vasoconstriction. How the coupling between the pulmonary arterial (PA) circulation and the right ventricle (RV) is affected by normovolemic hemodilution and by the composition of replacement solutions remains unknown. Therefore, the effects of isotonic and hypertonic saline hydroxyethylstarch solutions on the ...

Pulmonary vasoconstriction and vascular remodeling are two major causes for elevated pulmonary vascular resistance and pulmonary arterial pressure in patients with idiopathic pulmonary arterial hypertension (IPAH). An increase in cytosolic free Ca(2+) concentration ([Ca(2+)](cyt)) in pulmonary artery smooth muscle cells (PASMC) is a major trigger for pulmonary vasoconstriction and an ...

Previous studies have suggested an association between subclinical hypothyroidism and coronary artery disease that could be related to changes in serum lipids or endothelial dysfunction. Thirty-two female subclinical hypothyroidism patients were randomly assigned to 12 months of L-thyroxine replacement or no treatment. Endothelial function was measured by the flow-mediated vasodilatation ...

Vasodilation of lower leg arterioles is impaired in animal models of chronic peripheral ischemia. In addition to arterioles, feed arteries are a critical component of the vascular resistance network, accounting for as much as 50% of the pressure drop across the arterial circulation. Despite the critical importance of feed arteries ...

There is insufficient evidence to guide stent usage following angioplasty in subclavian artery stenosis. The aim of this review was to determine whether stenting is more effective than angioplasty alone for stenosis of the subclavian artery. The Cochrane Peripheral Vascular Diseases Group searched their Specialised Register (last searched August 2011) ...
