BACKGROUND: The treatment strategy and the correct incidence of near occlusion (NO) of the internal carotid artery (ICA) is still controversial. In routine radiological imaging NO can easily be misdiagnosed as complete occlusion and there is no consensus on the standard treatment strategy. PURPOSE: To present our perioperative and long-term follow-up results of ICA NO patients treated with carotid artery stenting (CAS). MATERIAL AND METHODS: Between 2004-2014 a total of 182 patients with ICA NO were evaluated for CAS...

BACKGROUND: Embolic protection devices can prevent atherosclerotic emboli during carotid stenting. Newer proximal protection devices reverse flow in the internal carotid artery (ICA), leading to reduction in perioperative microemboli. The risk of stroke is high for carotid stenting of ICA lesions with a length >10 mm and/or angiographic string sign. OBJECTIVE: We aimed to evaluate the safety outcomes of proximal embolic protection device usage in this high-risk group...

OBJECTIVE: Chronic kidney disease (CKD) increases morbidity and mortality after vascular procedures and adversely affects late survival of patients. The presence of CKD also confers increased risk of stroke in patients with asymptomatic carotid stenosis. Patients undergoing carotid intervention in the Vascular Study Group of New England database were stratified by CKD status referable to periprocedural and late outcomes. METHODS: All carotid artery stenting and carotid endarterectomies (CEAs) performed from 2003 to 2013 were stratified by CKD severity as mild (estimated glomerular filtration rate [eGFR] >60 mL/min/1...

AIMS: Glucagon like peptide 1 (GLP-1) analogues and dipeptidyl peptidase IV (DPP-4) inhibitors reduce atherosclerosis progression in type 2 diabetes mellitus (T2DM) patients and are associated with morphological and compositional characteristics of stable plaque phenotype. GLP-1 promotes the secretion of adiponectin which exerts anti-inflammatory effects through the adaptor protein PH domain and leucine zipper containing 1 (APPL1). The potential role of APPL1 expression in the evolution of atherosclerotic plaque in TDM2 patients has not previously evaluated...

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 AND PURPOSE: Cervical internal carotid artery occlusion can present with varied clinical manifestations such as transient ischemic attack, stroke, and chronic ocular ischemia, or can be asymptomatic. The outcome in these patients is considerably influenced by cerebral hemodynamic compensatory adaptation of the intracranial collateral pathways. Our aim was to study whether collateral circulation as assessed by CT angiography can predict 3-month outcome and initial stroke severity in patients with symptomatic cervical ICA occlusion...

BACKGROUND AND AIMS: We have recently reported that monocytes can undergo functional and transcriptional reprogramming towards a long-term pro-inflammatory phenotype after brief in vitro exposure to atherogenic stimuli such as oxidized LDL. This process is termed 'trained immunity', and is mediated by epigenetic remodeling and a metabolic switch towards increased aerobic glycolysis. We hypothesize that trained immunity contributes to atherogenesis. Therefore, we investigated the inflammatory phenotype and epigenetic remodeling of monocytes from patients with and without established atherosclerosis...

Current guidelines recommend searching for asymptomatic target organ damage (TOD) in treated as well as in untreated hypertensive patients because that TOD is an intermediate stage in the continuum of cardiovascular diseases and because it is a determinant of patients' overall cardiovascular risk. Large amount of data demonstrated that target organ measures can predict cardiovascular mortality and morbidity. Nowadays, several non-invasive techniques are available and recommended to assess TOD. The clinical values and limitations of the TOD measures on heart, arteries, kidney and brain, including ECG- or echocardiogram- diagnosed LVH or other heart lesions, carotid intima-media thickness and plaques, carotid-femoral pulse wave velocity and ankle-brachial index, microalbuminuria, and estimated glomerular filtration rate, fundoscopy and brain imaging will be discussed...

Here we provide the correlation among different carotid ultrasound (US) variables to assess echogenicity n standard carotid US and to assess intraplaque neovascularization on contrast enhanced US. We recruited 45 consecutive subjects with an asymptomatic≥50% carotid artery stenosis. Carotid plaque echogenicity at standard US was visually graded according to Gray-Weale classification (GW) and measured by the greyscale median (GSM), a semi-automated computerized measurement performed by Adobe Photoshop(®)...

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...

BACKGROUND: The prevalence of asymptomatic unruptured intracranial aneurysms (AUIA) in a Southeast Asian population has not been previously studied. Knowing the disease burden and population at risk can assist us in making informed decisions when managing AUIAs. We aimed to determine if the local prevalence of AUIAs differed from other populations in the published literature. METHODS: Magnetic resonance angiography radiology reports and images for 4572 patients between January 2013 and January 2014 were reviewed for AUIAs...

OBJECTIVES: The aim of this study was to: 1) provide tissue validation of quantitative T2 mapping to measure plaque lipid content; and 2) investigate whether this technique could discern differences in plaque characteristics between symptom-related and non-symptom-related carotid plaques. BACKGROUND: Noninvasive plaque lipid quantification is appealing both for stratification in treatment selection and as a possible predictor of future plaque rupture. However, current cardiovascular magnetic resonance (CMR) methods are insensitive, require a coalesced mass of lipid core, and rely on multicontrast acquisition with contrast media and extensive post-processing...

BACKGROUND AND PURPOSE: High-sensitivity C-reactive protein (hs-CRP) is a risk indicator for atherosclerosis. However, the association between hs-CRP and early carotid atherosclerosis progression is not well established. We undertook a prospective, community-based, observational study to address this question. METHODS: Common carotid artery intima-media thickness (IMT) and hs-CRP values were measured at baseline and after 2 years of follow-up in subjects ≥40 years of age who were participating in the Asymptomatic Polyvascular Abnormalities Community study...
