Objective: Secreted frizzled related protein 5 (SFRP5) is a novel anti-inflammatory adipokine that is implicated in metabolic and cardiovascular disease (CVD). However, little is known about the relevance of SFRP5 with asymptomatic hypertensive target organ damages (TODs). We aimed to investigate the association between SFRP5 and TOD in a large population. Clinical trial registration: NCT02368938. Methods: A total of 1,745 community-dwelling elderly subjects aged over 65 years from northern Shanghai were recruited in the study...

This study aimed to test the hypothesis that the risk of major adverse cardiovascular events (MACE) is similar for subjects with asymptomatic mild and moderate carotid artery stenosis (CAS). We enrolled a total of 453 subjects with asymptomatic CAS (30-69%) detected on baseline screening Doppler ultrasound (DUS) examination between January 2008 and December 2010. The follow-up DUS findings and MACE occurrence (fatal or nonfatal myocardial infarction or stroke and all-cause mortality) were compared between subjects with mild (30-49%) and moderate (50-69%) CAS during the 8-year follow-up period...

We aim to perform a systematic review and meta-analysis to investigate outcomes of treatment strategies for asymptomatic carotid disease. We searched electronic bibliographic sources (MEDLINE, EMBASE, CINAHL and CENTRAL) to identify randomised controlled trials (RCT) reporting comparative outcomes of carotid endarterectomy (CEA), carotid stenting (CAS) and best medical therapy (BMT) in asymptomatic carotid disease. We performed pairwise meta-analysis applying random or fixed-effects models and reported the results as the odds ratio (OR) or risk difference (RD) and 95% confidence interval (CI)...

BACKGROUND: Cerebrovascular events are frequently associated with hemodynamic disturbance caused by internal carotid artery (ICA) stenosis. It is challenging to determine the ischemia-related carotid stenosis during the intervention only using digital subtracted angiography (DSA). Inspired by the performance of well-established FFRct technique in hemodynamic assessment of significant coronary stenosis, we introduced a pressure-based carotid arterial functional assessment (CAFA) index generated from computational fluid dynamic (CFD) simulation in DSA data, and investigated its feasibility in the assessment of hemodynamic disturbance preliminarily using pressure-wired measurement and arterial spin labeling (ASL) MRI as references...

BACKGROUND: Hypoglossal nerve deficit is a possible complication caused by carotid endarterectomy (CEA). The accidental injury of the hypoglossal nerve during surgery is one of the major reasons for permanent hypoglossal nerve palsy. In this study, we investigated the usefulness of intraoperative mapping of the hypoglossal nerve to identify this nerve during CEA. METHODS: Five consecutive patients who underwent CEA for the treatment of symptomatic or asymptomatic carotid artery stenosis were studied...

Carotid intima-media thickness (CIMT) measurement and carotid plaque detection by B-mode ultrasound are frequently used as surrogates to predict coronary artery disease (CAD). However, their systematic use in routine clinical management of asymptomatic patients with diabetes mellitus (DM) has not been studied. The aim of the study was to identify carotid parameters that predict cardiovascular events in patients with asymptomatic type 2 DM by evaluating the relation between carotid disease and CAD. This multicenter, observational, prospective study included 259 asymptomatic patients with type 2 DM followed-up for 34 months after measurement of CIMT and carotid plaque with carotid ultrasound, and CAD assessment with computed tomography coronary angiography...

BACKGROUND: Carotid artery stenosis (CAS) is the atherosclerotic narrowing of the proximal internal carotid artery (ICA) and one of the main causes of stroke. Elevated expression of the pleiotropic proinflammatory cytokine, interleukin-18 (IL18), has been shown in human atherosclerotic plaques. AIMS: To investigate whether IL18 and interleukin-18 binding protein (IL18BP) mRNA expression and IL18 -137 G/C (rs187238) variants are associated with CAS development. STUDY DESIGN: Case-control study...

OBJECTIVE: Black patients undergoing carotid endarterectomy (CEA) in the United States are more often symptomatic at presentation and have more comorbidities compared with white patients. However, the impact of race on outcomes after CEA is largely unknown. METHODS: We identified CEA patients in the Vascular Quality Initiative registry (2012-2017) and compared them by race (black vs white). All other nonwhite races (891 [1.4%]) and Hispanics (2222 [3.4%]) were excluded...

BACKGROUND: Carotid artery occlusive disease can cause stroke by embolization, thrombosis, and hypoperfusion. The majority of strokes secondary to cervical carotid atherosclerosis are believed to be of embolic etiology. However, cerebral hypoperfusion could be an important factor in perioperative stroke. We retrospectively reviewed the stump pressure (SP) of carotid endarterectomy (CEA) of patients at Pennsylvania Hospital to identify whether physiologic perfusion differences account for differences in perioperative stroke rates, particularly in octogenarians...

Background: A study was conducted as to whether the early diagnosis of coronary heart disease in asymptomatic subjects with advanced atherosclerosis of the carotid artery which additionally shows at least one risk factor is successful using ultrasound technology. Methods: Within the scope of an occupational screening program using subjects from diverse employment sectors, people were given the opportunity to determine their risk of heart attack. During the study the total plaque area (TPA), the maximum plaque thickness in the carotid artery and the PROCAM-Scores of 3,748 healthy men and 2,260 healthy women between the ages of 20 and 64 years were determined...

BACKGROUND: The pathophysiological mechanisms responsible for the disparity in stroke risk between asymptomatic and symptomatic carotid stenosis patients are not fully understood. The functionally important reticulated platelet fraction and reticulocytes could play a role. OBJECTIVES: We performed a prospective, multi-centre, observational analytical study comparing full blood count parameters and platelet production/turnover/activation markers in patients with asymptomatic versus recently symptomatic moderate (≥ 50-69%) or severe (≥ 70-99%) carotid stenosis...

INTRODUCTION: Splenosis is defined as the heterotopic autoimplantation of splenic tissue following trauma to or surgery on the spleen. CLINICAL CASE: We present a case of an asymptomatic 73-year-old male in whom hypervascular lesions were detected during routine exams. The patient reported a history of carotid artery surgery and cholecystectomy; he had a laparotomy incision from childhood but was unaware of the reason for it. The patient exhibited slightly elevated carcinoembryonic antigen (CEA) levels...

Atherosclerosis is a type of cardiovascular disease which may cause stroke. It is due to the deposition of fatty plaque in the artery walls resulting in the reduction of elasticity gradually and hence restricting the blood flow to the heart. Hence, an early prediction of carotid plaque deposition is important, as it can save lives. This paper proposes a novel data mining framework for the assessment of atherosclerosis in its early stage using ultrasound images. In this work, we are using 1353 symptomatic and 420 asymptomatic carotid plaque ultrasound images...

OBJECTIVE: To quantify non-coronary vascular calcifications (VC) in asymptomatic patients at low-intermediate cardiovascular risk by a new color Doppler ultrasound (DUS)-based score (the carotid, aortic, lower limbs calcium score, CALCs), and to correlate this score with classical parameters associated with cardiovascular risk [carotid intima media thickness (IMT), and arterial stiffness (AS)]. PATIENTS AND METHODS: All consecutive asymptomatic patients who underwent a screening DUS of non-coronary circulation were evaluated and patients at low-intermediate cardiovascular risk were selected according to Framingham risk score (FRS)...

BACKGROUND: Molecular imaging of carotid plaque vulnerability to atheroembolic events is likely to lead to improvements in selection of patients for carotid endarterectomy (CEA). The aims of this study were to assess the relative value of endothelial inflammatory markers for this application and to develop molecular ultrasound contrast agents for their imaging. METHODS: Human CEA specimens were obtained prospectively from asymptomatic (30) and symptomatic (30) patients...

BACKGROUND AND PURPOSE: A recurrent duplication of chromosome 16p13.1 was associated with aortic dissection as well as with cervical artery dissection. We explore the segregation of this duplication in a family with familial aortic disease. METHODS: Whole exome sequencing (WES) analysis was performed in a patient with a family history of aortic diseases and ischemic stroke due to an aortic dissection extending into both carotid arteries. RESULTS: The index patient, his affected father, and an affected sister of his father carried a large duplication of region 16p13...

BACKGROUND AND AIMS: Plaque border irregularity is a known imaging characteristic of vulnerable plaques, but its evaluation heavily relies on subjective evaluation and operator expertise. Aim of the present work is to propose a novel fractal-analysis based method for the quantification of atherosclerotic plaque border irregularity and assess its relation with cardiovascular risk factors. METHODS AND RESULTS: Forty-two asymptomatic subjects with carotid stenosis underwent ultrasound evaluation and assessment of cardiovascular risk factors...

Background: Both hypertensive and atherosclerotic processes contribute to common carotid artery intima-media thickness (CCA-IMT). Elevated CCA-IMT may be indicative of subclinical cerebrovascular disease; however, its role in the absence of concomitant carotid artery plaque is uncertain, and few studies have examined associations in black populations. Materials and Methods: At cohort visit 3 (1993-1995) a subset of stroke-free participants (641 blacks and 702 whites, mean age 63) from the Atherosclerosis Risk in Communities (ARIC) study was imaged by brain MRI and carotid ultrasound...
