BACKGROUND: Incidental paranasal sinusitis (IPS) is common on imaging for non-sinusitis disorders, usually without symptoms or obstructive features, and possibly arising from periodontitis (PD). PD associations with atherosclerosis have been widely reported. We test if IPS may also be associated with atherosclerosis. METHODS: IPS was scored retrospectively in a random sample of 180 magnetic resonance (MR) brain scans and compared with chart review for atherosclerosis (all subtypes), rhinosinusitis, and related factors (smoking, asthma, and relevant surgery)...

OBJECTIFS: La mortalité dans la polyarthrite rhumatoïde (PR) est élevée en raison de la survenue d'événements cardiovasculaires. Le risque cardiovasculaire augmenté dans la PR est essentiellement lié à l'état inflammatoire chronique ainsi que d'autres facteurs comme les traitements, notamment la corticothérapie qui jouerait un rôle capital. Nous rapportant le cas d'une gangrène survenue sur athérosclérose ayant compliqué une polyarthrite rhumatoïde. MéTHODES: Patiente de 53 ans, connue et traitée pour une polyarthrite rhumatoïde depuis 20 ans, était admise pour exploration d'une ostéoporose avec une gangrène sèche du gros orteil droit...

INTRODUCTION: Besides their blood pressure-lowering effects, olmesartan medoxomil and amlodipine besylate exhibit additional anti-inflammatory mechanisms in atherosclerosic disease. Most of the studies investigating the effects of atherosclerosis focused on early atherosclerotic lesions, whereas lesions in human disease, at the time when medical treatment is started, are already well established. Therefore, we set up a model of advanced atherosclerosis and investigated the effects of olmesartan medoxomil, amlodipine besylate, and the combination of both on atherosclerotic lesion size and lesion composition...

OBJECTIVE: Glipitins are widely used for the treatment of type 2 diabetic patients. In addition to their improvement of glycemic control, animal studies have suggested an independent anti-atherosclerotic effect of gliptins. Nevertheless, recent clinical trials regarding long-term effects of gliptin therapy on vascular events have been disappointing. This discrepancy led us to better dissect the functional role of SDF-1/CXCR4 signaling as a potential mechanism underlying gliptin action...

OBJECTIVE: The aim of this review is to examine the role of polymorphonuclear neutrophils (PMNs) in the evolution of atherosclerosis. INTRODUCTION: While the role of PMNs in the evolution of atherosclerosic process has failed until recently to attract much attention, a body of research carried out over the last decade has disclosed the unexpectedly complex behavior of these cells, unraveling an unexpected key role for PMNs in the onset and progression of atheroma...

Heart disease is the most common cause of death in patients with chronic kidney disease (CKD), particularly in those receiving dialysis. Atherosclerosic cardiovascular (CV) disease (CVD) accounts for a large number of these deaths. Atherosclerosis is accelerated in patients with CKD due predominantly to the high prevalence of traditional CVD risk factors in the CKD population. CKD aggravates pre-existent traditional risk factors such as hypertension and dyslipidemia due to secondary renal parenchymal hypertension and secondary dyslipidemia...

This is the case of a 77 year-old man with previous coronary by-pass grafting. After the occlusion of the saphenous vein graft to marginal branch, corrected by angioplasty and stenting with a bare metal stent (BMS), during the next 4 years he experienced multiple further episodes of in-stent restenosis of the first BMS. Angioplasty was performed each time. After 4 months since the last procedure, he had new episode of unstable angina. An EKG-gated, 64-row multislice CT (MSCT) examination was performed to evaluate the venous graft lumen, showing high-grade in-stent restenosis...

PURPOSE: Platelets play a key role in haemostasis and wound healing, contributing to formation of vascular plugs. They are also involved in formation of atherosclerosic plaques. Some traditional diets, like the Mediterranean diet, are associated with a lower risk of cardiovascular disease. Components in these diets may have anti-platelet functions contributing to their health benefits. METHODS: We studied the effects of alperujo extract, an olive oil production waste product containing the majority of polyphenols found in olive fruits, through measurement of effects on platelet aggregation and activation in isolated human platelets, and through identification of changes in the platelet proteome...

BACKGROUND: Vascular risk factors predispose to vertebrobasilar ischemia. Cervical osteophytes can impinge on the vertebral artery causing mechanical occlusion during head turning. Presentation with vertigo in such instances is a common finding. CASE PRESENTATION: A patient with obesity, hyperlipidemia, hypertension, cervical spondylosis, and vertigo triggered by head rotation is presented. She responded to antihypertensive and lipid-lowering drugs, vestibular sedative and application of cervical collar...

The amino acid L-arginine is the substrate for endothelial nitric oxide synthesis. The endothelium is capable of producing asymmetric dimethylargine (ADMA) (L-arginine methylated). ADMA is able to compete with L-arginine in nitric oxide (NO) production and inhibits oxide nitric synthase activity. Elevated blood levels of ADMA can block the synthesis of NO, and induce endothelial dysfunction, which may lead to the initiation and progression of atherosclerosic vascular disease. Prospective clinical studies in different patients populations suggest that ADMA is a new marker in cardiovascular disease and is to able to predict new cardiovascular events...

Iatrogenic non-penetrating arterial injuries have been reported following primary and revision hip arthroplasties. We report a patient who developed acute limb ischaemia after dynamic hip screw fixation was performed for an unstable intertrochanteric fracture. We discuss a previously unreported mechanism of traction creating tension on the atherosclerosed vessels and medial retraction tenting and breaking the vessel wall lining. This case highlights a serious complication in one of the most commonly performed hip surgeries...

Serotonin (5-hydroxytryptamine) has been recently shown to be an important mediator of coronary vasospasm. Its divergent effect on normal and atherosclerosed arteries has been demonstrated in both animal and human studies. We present a case of coronary vasospasm in a 55-year-old man with repeated episodes of chest pain following coronary percutaneous intervention. Repeat angiography demonstrated no reocclusion or complication. The patient's symptoms were resistant to treatment with maximum doses of two calcium channel antagonists and oral and intravenous nitrates, but responded to cyproheptadine, a nonselective serotonin antagonist...

PURPOSE: Ethnic differences in the distribution of atherosclerosis in the brain-supplying vessels are well described. However, only scarce data exist on the prevalence of extracranial carotid artery stenosis in Taiwanese patients who have had a single ischemic stroke. METHODS: Color-coded duplex sonography was used to evaluate the carotid arteries in a hospital-based study on 276 consecutive first-time Taiwanese stroke patients. Significant atherosclerotic lesions of the internal carotid arteries (ICA) were defined as a stenosis of more than 50% or an occlusion...
