Abstract
INTRODUCTION Patients with coronary heart disease often suffer from damage in another vessel which has, in some cases, no clinical signs. These combined conditions are important to be diagnosed in order to treat the patients thoroughly. AIM To estimate the frequency of other peripheral atheromatous injuries especially carotid artery disease, Abdominal aortic aneurysm (AAA) and Peripheral artery disease (PAD) in patients with coronary disease which were enrolled in the cardiology department of the university hospital of Constantine, Algeria. PATIENTS AND METHODS This descriptive cross-sectional monocentre study was carried out in the cardiovascular exploration unit in the university hospital of Constantine, Algeria. Enrolled patients had at least one significative coronary injury≥50 in one of the major coronary arteries. All of the patients have had an ultrasound examination (supra-aortic trunks doppler, aorta and inferior limbs doppler). Data were processed and analysed using SPSS 22 software. RESULTS The frequency of the association PAD with CAD was 34.7% which accounts for the highest frequency. Haemodynamic carotid injury (≥50%) and AAA were respectively associated with CAD in 12% and 4.6% of the cases. The triple associations CAD with AAA and Haemodynamic carotid injury was observed in 2.67% of the cases while CAD with PAD and carotid artery stenosis (≥50%) in 6.67% of the cases. The frequency of the association CAD with PAD and AAA was estimated at 3.66%. CONCLUSION Coronary artery disease goes often hand in hand with other heart conditions, which should be systematically considered in patients with CAD. Clinical examination along with recommended non-invasive imaging techniques can help improve the medical assessment of patients with CAD. Only with these means, thorough personalised and cost-beneficial medical care can be obtained.

Abstract
RATIONALE Carotid stump syndrome is a cerebral infarction caused by an embolus formed subsequent to the vortex of blood flow from the occluded stump, which then moves through the collateral vessels into the brain. The covered stent and stent-assisted coil embolization stump are the effective interventions for the carotid artery stump. PATIENT CONCERNS A 71-year-old man twice experienced left limb weakness; diffusion weighted imaging confirmed the diagnosis of cerebral infarction. Cervical computed tomography angiography, intracranial magnetic resonance angiography, and digital subtraction angiography were conducted to evaluate collateral circulation, intraluminal composition, and shape of the carotid stump. DIAGNOSES The patient was diagnosed with cerebral infarction and right carotid stump syndrome. INTERVENTION The patient underwent interventional recanalization of the occluded internal carotid artery, which relieved his symptoms and led to satisfactory therapeutic outcomes during the clinical follow-up. OUTCOMES A 9-month clinical follow-up revealed no stroke recurrence. LESSONS Interventional recanalization for the carotid artery stump syndrome is feasible. Accurate preoperative evaluation including collateral circulation, intraluminal composition, and shape of the carotid stump can assure a successful vascularization and guided management.

Abstract
BACKGROUND AND AIM Proprotein convertase subtilisin/kexin type 9 (PCSK9) is rapidly gaining attention as a potential risk of developing atherosclerosis due to its crucial role in the regulation of low-density lipoprotein cholesterol (LDL-C) metabolism. The present study investigated the relationship between serum PCSK9 levels and early atherosclerosis as assessed by carotid intimal-medial thickness (CIMT) and brachial-ankle pulse wave velocity (ba-PWV) in newly diagnosed type 2 diabetes mellitus (T2DM). METHODS AND RESULTS A total of 100 newly diagnosed T2DM were enrolled and further divided into the thickened CIMT group (n = 41) and the non-thickened CIMT group (n = 59) according to the results of color Doppler ultrasonography. Serum PCSK9 levels, CIMT, ba-PWV, and metabolic parameters were measured. Patients in the thickened CIMT group had higher serum PCSK9 levels than patients in the non-thickened CIMT group (all P < 0.05). CIMT and ba-PWV were both positively correlated to serum PCSK9 levels, while serum PCSK9 levels were positively correlated to white blood cell count, neutrophil, lymphocyte, and high-sensitivity C-reactive protein (P < 0.05). Multiple linear regression indicated that serum PCSK9 level was an independent predictor of CIMT (β = 0.637, P < 0.001) and ba-PWV (β = 0.600, P < 0.001). Binary logistic regression analysis showed that serum PCSK9 levels were independent risk factors of thickened CIMT [OR = 1.120, 95%CI (1.041-1.204), P = 0.002]. CONCLUSION Serum PCSK9 levels are significantly correlated with CIMT and ba-PWV, independent of CAD risk factors. Therefore, serum PCSK9 level may have the potential to serve as a prescriptive biomarker for early arteriosclerosis in newly diagnosed T2DM.

Abstract
Carotid ultrasonography is a non-invasive, simple and inexpensive modality to assess the severity of atherosclerosis. This article reviews related articles, summarizes the rationale for the application of carotid ultrasonography in clinical practice, and addresses the features and the limitations of carotid ultrasonography in cardiovascular risk prediction. Numerous large studies have confirmed that various carotid ultrasound measures, such as carotid intima-media thickness, the presence or absence of carotid plaque, plaque number and plaque area, can be independent predictors of cardiovascular diseases in individuals with and without diabetes mellitus. Furthermore, many studies showed that the use of carotid intima-media thickness (especially maximum intima-media thickness, including plaque thickness) and/or carotid plaque in addition to traditional risk factors significantly improved the prediction of the occurrence of cardiovascular diseases, while controversy remains. Several studies showed that the progression of carotid intima-media thickness also can be a surrogate end-point of cardiovascular events. However, the accumulated evidence has not been sufficient. Further study with sufficient power should be carried out. As plaque disruption, which plays a crucial role in the pathogenesis of cardiovascular events, is dependent on the content of lipid in the atheroma and the thickness of the fibrous cap, tissue characterization of a plaque might be useful for determining its fragility. Interestingly, recent studies have shown that ultrasonic tissue characterization of carotid lesions could improve the prediction ability of future cardiovascular diseases. Thus, carotid ultrasonography is a useful modality for better clinical practice of atherosclerosis in patients with diabetes.

Abstract
BACKGROUND Epicardial fat is recognized as active endocrine organ and as emerging risk factor for cardio-metabolic diseases. The aim of this study was to explore the relationship between epicardial fat and carotid intima-media thickness in type 2 diabetes patients. METHODS Epicardial fat thickness was measured in 76 type 2 diabetes patients without clinical atherosclerotic cardiovascular disease and 30 age- and sex-matched controls. In addition to laboratory tests, all patients underwent transthoracic echocardiography for epicardial fat thickness and ultrasonographic examination of carotid intima-media thickness. RESULTS Patients with diabetes had higher epicardial fat thickness and carotid intima-media thickness than those of the controls (6.23 ± 1.27 mm vs 4.6 ± 1.03 mm, p < 0.001 and 0.77 ± 0.150 mm vs 0.58 ± 0.08 mm, p < 0.001, respectively). Epicardial fat thickness was correlated significantly with age, duration of type 2 diabetes, body mass index, waist circumference, HbA1c, carotid intima-media thickness, Homeostasis Model Assessment Index for insulin resistance and lipid profile in the type 2 diabetic patients. Stepwise regression analysis showed that carotid intima-media thickness, duration of diabetes, triglyceride and body mass index were the independent predictors of epicardial fat thickness, with carotid intima-media thickness the most important predictor (β = 3.078, t = 4.058, p < 0.001). Receiver operating characteristic curve analysis was done and cut-off high-risk epicardial fat thickness value of 6.1 mm was determined with a sensitivity and specificity of 71.4% and 72%, respectively. CONCLUSION Patients with type 2 diabetes have higher carotid intima-media thickness and epicardial fat thickness. Epicardial fat thickness was found to be a strong predictor of subclinical atherosclerosis.

Abstract
Tumor emboli due to a sarcoma are usually confirmed by an autopsy or operative findings. A sarcoma embolus in an acute stroke patient is rare. We herein report a 37-year-old man with acute stroke caused by internal carotid artery occlusion who underwent embolectomy. A histopathological analysis of an embolus obtained with a mechanical retriever device was diagnosed as undifferentiated sarcoma. This is the first case of extracardiac sarcoma extraction via mechanical retrieval performed during intervention for acute ischemic stroke. A histopathologic evaluation with embolectomy is important for diagnosing tumor emboli.

Abstract
BACKGROUND Type 1 diabetes is associated with increased risk of cardiovascular disease and the diabetic complication cardiovascular autonomic neuropathy in itself entails increased cardiovascular risk by mechanisms not yet fully understood. Arterial calcification is an important predictor of cardiovascular events; the aim of this study was to investigate the level of generalised arterial calcification in patients with long-term, normoalbuminuric type 1 diabetes and the association with cardiovascular autonomic neuropathy, as these factors have not been investigated in type 1 diabetes. METHODS Participants were examined for calcification of coronary and carotid arteries through non-contrast multi-detector computed tomography scans. Generalised arterial calcification was defined as the presence of calcium in both the coronary and carotid arteries. RESULTS A total of 53 patients with type 1 diabetes were included. Coronary and carotid artery calcium scores were correlated ( r = 0.720, p < 0.0001). Cardiovascular autonomic neuropathy was associated with increased coronary ( p = 0.002) and carotid ( p = 0.001) artery calcium scores. Seventeen of 20 patients with cardiovascular autonomic neuropathy (85%) demonstrated generalised arterial calcification compared to 11 (33%) patients without cardiovascular autonomic neuropathy; patients with cardiovascular autonomic neuropathy had an odds ratio of 11.3 (95% confidence interval = 2.7-47.1, p < 0.001) for generalised arterial calcification. CONCLUSION Cardiovascular autonomic neuropathy is associated with increased level of generalised arterial calcification in patients with normoalbuminuric, long-term type 1 diabetes.

Abstract
BACKGROUND AND AIMS The relationship between dietary intake and carotid intima media thickness (IMT) and pulse wave velocity (PWV) in individuals with type 1 and type 2 diabetes has not been well studied. We investigated the association between dietary intake and common carotid artery intima media thickness (CCA IMT) and PWV in a cohort with type 1 and type 2 diabetes. METHODS AND RESULTS A one-year randomised controlled trial was conducted to investigate the effect of improving dietary quality on CCA IMT. These subjects were followed up again approximately 12 months after the completion of the trial (i.e. approximately 24 month since baseline). The study cohort included 87 subjects that had dietary intake and CCA IMT measured at baseline and after a mean of 2.3 years' follow-up. PWV was measured in a subsample of this cohort. Age and baseline mean CCA IMT were strongly associated with mean CCA IMT at 24 months. After adjustment for age and baseline mean CCA IMT, baseline consumption of carbohydrate (r = -0.28; p = 0.01), sugars (r = -0.27; p = 0.01), fibre (r = -0.26; p = 0.02), magnesium (r = -0.25; p = 0.02) and the Alternate Health Eating Index (AHEI) score (r = -0.23; p = 0.03) were inversely associated with mean CCA IMT at 24 months. Mixed linear modelling showed an interaction between mean CCA IMT and AHEI at baseline (p = 0.024). Those who were in the highest AHEI tertile at baseline had greater CCA IMT regression at 24 months compared to those in the lowest tertile, after adjustment for baseline age, BMI, smoking pack years, time since diabetes diagnosis, and mean arterial pressure at baseline (mean -0.043 mm; 95% CI -0.084, -0.003; p = 0.029). CONCLUSIONS In this prospective analysis greater diet quality at baseline, as measured by the AHEI, was associated with greater CCA IMT regression after approximately two years. This suggests that greater diet quality is associated with better longer term vascular health in individuals with type 1 and type 2 diabetes.

Abstract
BACKGROUND The cardiovascular disease risk was assessed in metabolically healthy obese (MHO) children, obese children with metabolic disorders (MUO), and to a control group of normal-weight children using carotid intima-media thickness (CIMT). METHODS Participants were 204 obese children (114 M, 90 F), including 162 MUO (74 M, 88 F) and 42 MHO (24 M, 18 F), and 99 gender- and age-matched controls (45 M, 54 F). Glucose, triglycerides, total cholesterol, high-density and low-density lipoprotein cholesterol, and other serum values were determined in peripheral blood. Anthropometric parameters, blood pressure, and a carotid Doppler ultrasound scan were also acquired. The mean CIMT of obese subjects and controls was compared by analysis of variance. Abnormality of even one of the metabolic parameters assessed involved assignation to the MUO group. Mean CIMT was compared in MHO and MUO children. RESULTS Mean CIMT in control children was 402.97 ± 53.18 μm (left carotid artery) and 377.85 ± 52.47 μm (right carotid artery). In MHO and MUO patients CIMT was respectively 453.29 ± 62.04 and 460.17 ± 92.22 μm (left carotid artery) and 446.36 ± 49.21 and 456.30 ± 85.7 μm (right carotid artery). The mean CIMT was not significantly different in MUO and MHO children, whereas it showed a significant difference between both groups of obese children and controls (p < 0.01). CONCLUSION CIMT was significantly greater in obese patients, also in those without metabolic alterations, than in normal-weight children. Obesity is therefore an important risk factor for cardiovascular disease in itself, also in the absence of metabolic abnormalities.

Abstract
PURPOSE Carotid blowout syndrome (CBS) is a catastrophic complication of aggressive treatment of head and neck cancer. Early detection of bleeding points with embolization is a life-saving procedure; however, some bleeding points may be difficult to identify. Our aim was to determine whether guidewire manipulation (GWM) could be used to verify bleeding point locations in patients with CBS. METHODS Of the 92 patients with CBS referred for embolization in a 5-year period, 14 men and one woman (mean age 58 years) had bleeding points at locations that could not be definitely determined. We used GWM to verify the presence of these bleeding points. We assessed the anatomy of the ruptured arteries, technical details of GWM, and the angiographic and clinical outcomes. RESULTS Bleeding points were difficult to detect because of the presence of small arterial pouches (n = 6) or multiple small arterial pouches (n = 9) in the unilateral or bilateral carotid arteries. Bleeding point locations were accurately identified using GWM in the internal carotid artery (n = 7), carotid bulb (n = 4), or common carotid artery (n = 4). Balloon-assisted GWM was applied in one patient. Fiber coils (n = 15) and/or liquid adhesives (n = 2) were used to occlude the affected artery. Endovascular management was technically successful in all patients and resulted in immediate cessation of hemorrhage without recurrence in a mean 22-month clinical follow-up. CONCLUSION GWM is a simple and effective method for verifying bleeding points in ruptured arteries and preventing erroneous occlusion by embolization.

Abstract
Lipoprotein(a) [Lp(a)] consists of an LDL-like particle in which the apolipoprotein B100 is covalently bound to apolipoprotein(a) by a single disulfide bond. Lp(a) is synthesized in the liver and its plasma concentration varies from 0 to 400 mg/dl. Increased level of Lp(a) is considered to be an independent risk factor of cardiovascular diseases and coronary heart disease. Data about the significance of hyperlipoproteinemia(a) in the development of atherosclerosis of peripheral (lower limbs) and carotid arteries remain controversial. This review is devoted to Lp(a), its relationship with atherosclerosis of different vascular beds, as well as modern possibilities of hyperlipoproteinemia(a) correction.

Abstract
In patients with cerebral infarction (CI), elevated serum uric acid (UA) level may exacerbate the occurrence and development of carotid atherosclerosis (AS). Our study intended to explore the underlying mechanism. We enrolled 86 patients with CI, and divided them into four groups: Non-AS, AS-mild, AS-moderate, and AS-severe groups; the levels of UA and oxidative stress-related factors in serum were detected. The middle cerebral artery occlusion (MCAO) model was used to stimulate CI in rats, and different doses of UA were administrated. The levels of oxidative stress-related factors in serum were detected. Hematoxylin & eosin (H&E) staining was used to observe the morphological alterations, and the apoptotic cell death detection kit was used to detect apoptotic cells. Increased UA concentration and enhanced oxidative stress were found in AS patients. H&E staining results showed that UA treatment exacerbated morphological damage in rats with MCAO, promoted oxidative stress, and enhanced vascular endothelial cell apoptosis in rats with MCAO.

Abstract
BACKGROUND AND AIMS Cardiovascular disease (CVD) is one of the leading causes of mortality in obese patients. We aimed to investigate the influence of significant weight loss following laparoscopic sleeve gastrectomy (LSG) on carotid intima media thickness (CIMT) and epicardial fat thickness (EFT) which are the independent predictors of subclinical atherosclerosis. METHODS AND RESULTS Patients were recruited for standard indications. A total of 105 patients (79 women and 26 men) with the mean age of 43.61 ± 12.42 were prospectively enrolled. On B-mode duplex ultrasound; the mean CIMT at the far wall of both left and right common carotid arteries were measured. EFT was measured on the free wall of the right ventricle at end-diastole from the parasternal long-axis view by standard transthorasic 2D echocardiography. Delta (Δ) values were obtained by subtracting sixth month values from the baseline values. Body mass index (BMI) was significantly reduced from 46.95 ± 7.54 to 33.54 ± 6.41 kg/m2 (p < 0.001) in sixth months after LSG. Both EFT and CIMT were significantly decreased after surgery (8.68 ± 1.95 mm vs. 7.41 ± 1.87 mm; p < 0.001 and 0.74 ± 0.13 mm vs. 0.67 ± 0.11 mm; p < 0.001 respectively). A significant correlation between ΔEFT and ΔBMI (r = 0.431, p < 0.001) was shown. ΔCIMT is significantly correlated with ΔEFT, ΔBMI and Δ systolic blood pressure (r = 0.310, r = 0.285 and r = 0.231 respectively, p < 0.05 for all). In multivariate stepwise linear regression analysis; among variables only ΔBMI was the independent predictor of ΔEFT (β = 153, p = 0.001). CONCLUSION Early atherosclerotic structural changes may be reversed or improved by sustained weight loss after LSG in asymptomatic obese patients.

Abstract
RATIONALE Wooden transorbital penetrating injury is an uncommon and serious trauma that may cause multiply complications. PATIENT CONCERNS Here we describe a 62-year-old Chinese woman with a transorbital penetrating injury caused by a long bamboo branch. DIAGNOSIS Computed tomography scan and magnetic resonance imaging showed the presence of a wooden foreign body. INTERVENTIONS Cerebrovascular digital subtraction angiography and temporary balloon occlusion were performed with general anesthesia. Anti-inflammatory therapy was subsequently administered. OUTCOMES Retention of wooden foreign body, orbital cellulitis, and traumatic aneurysm at the right internal carotid artery were diagnosed 1 month later. Coil embolization of the right internal carotid artery aneurysm and endoscopic sinus surgery were then performed, and postoperative condition was monitored and recorded. LESSONS Penetrating transorbital injury complications may occur because of retained wooden foreign bodies near the intracranial arteries. Reasonable surgical intervention and special attention should be performed in this kind of trauma.

Abstract
OBJECTIVES To compare patterns of vascular involvement using 18F-fluorodeoxyglucose-positron emission tomography computed tomography (FDG PET/CT) in patients with giant cell arteritis (GCA) and Takayasu's arteritis (TAK). METHODS A total of 130 consecutive 18F-FDG PET/CT scans performed during the disease course for evaluating disease activity in 15 GCA and 13 TAK patients were retrospectively examined by two nuclear physicians blinded to clinical data. Standardised uptake values (SUVmax) in 14 vascular districts including all the aortic segments and the main tributaries were measured. The average SUVmax value for each vascular district was also calculated. Principal component analysis (PCA) and agglomerative hierarchical cluster analysis (CA) were used to explore distribution patterns of vascular FDG uptake. RESULTS The aortic segments showed the highest SUV max values among the different districts in both GCA and TAK. SUV max values measured in the different districts were significantly higher in GCA compared to TAK, except for the axillary arteries. Regarding thoracic and abdominal aorta, ascending aorta and aortic arch had the highest correlation in both vasculitis (p<0.0001). CA confirmed that carotid, axillary, subclavian, iliac and femoral arteries clustered with their contralateral counterpart in both vasculitis. The 3 components of thoracic aorta clustered with abdominal aorta in TAK, while aortic arch clustered only with ascending aorta, and descending and abdominal aorta grouped together with iliac and femoral arteries in GCA. PCA analysis identified 3 different components for TAK and GCA explaining 72% and 71% of the total variance respectively in these two vasculitis. Confirming CA, a component including the entire aortic district was identified in TAK, but not in GCA. Similar results in PCA using averaged data were observed. CONCLUSIONS Strong similarities, but also a subtle skewing in terms of distribution patterns of arterial involvement assessed by SUVmax values were observed between GCA and TAK.

J Oral Maxillofac Surg 2018; 76:1447-1453.

Abstract
PURPOSE Males with rheumatoid arthritis (RA) are at an exceedingly high risk of adverse intraoperative ischemic events, given the role of systemic inflammation in the atherogenic process. We hypothesized that their panoramic images would demonstrate calcified carotid artery atheromas (CCAPs) significantly more often than those from a general population of similarly aged men. PATIENTS AND METHODS We implemented a retrospective observational study. The sample was composed of male patients older than 55 years of age who had undergone panoramic imaging studies. The predictor variable was the diagnosis of RA confirmed by a positive rheumatoid factor (RF) titer, and the outcome variable was the prevalence rate of CCAPs. The other major study variable was the level of RF among the patients evidencing CCAPs. The prevalence of CCAPs among the patients with RA was then compared with that of a historical general population of similarly aged men. Descriptive and bivariate statistics were computed, and the P value was set at .05. RESULTS Of the 100 men (mean age 69.89 ± 8.927 years) with RA, 29 (29%; mean age 72.10 ± 7.68 years) had atheromas (CCAP+). Of these 29 men, 25 (86%; mean age 71.88 ± 7.43 years) had a RF titer of ≥41 IU/mL, twice that of normal. A statistically significant (P < .05) association was found between a diagnosis of RA and the presence of an atheroma on the panoramic image compared with the 3% rate found in the historical cohort. CONCLUSIONS The results of the present study suggest that CCAP, a risk indicator of future adverse cardiovascular events, is frequently seen on panoramic images of male patients with RA and that these individuals routinely manifest high titer levels of RF, a biologic marker of inflammation. Oral and maxillofacial surgeons planning surgery for male patients with RA must be uniquely vigilant for the presence of these lesions.

Abstract
OBJECTIVES To investigate the association between serum uric acid level and the presence and progression of carotid atherosclerosis in Chinese individuals aged 75 years or older. DESIGN Case-control study. SETTING In a teaching hospital. PARTICIPANTS Five hundred and sixty-four elderlies (75 years or above) who underwent general health screening in our hospital were enrolled. MEASUREMENTS The detailed carotid ultrasound results, physical examination information, medical history, and laboratory test results including serum uric acid level were recorded, these data were used to analyze the relationship between serum uric acid level and carotid atherosclerosis. Then, subjects who underwent the second carotid ultrasound 1.5-2 years later were further identified to analyzed the relationship between serum uric acid and the progression of carotid atherosclerosis. RESULTS A total of 564 subjects were included, carotid plaque was found in 482 (85.5%) individuals. Logistic regression showed that subjects with elevated serum uric acid (expressed per 1 standard deviation change) had significantly higher incidence of carotid plaque (odds ratio, 1.37; 95% confidence interval, 1.07-1.75; P= 0.012) after controlling for other factors. A total of 236 subjects underwent the follow-up carotid ultrasound. Linear regression showed that serum uric acid level (expressed per 1 standard deviation change; 1 standard deviation = 95.5 μmol/L) was significantly associated with percentage of change of plaque score (P = 0.008). Multivariable linear regression showed that 1 standard deviation increase in serum uric acid levels was expected to increase 0.448% of plaque score (P = 0.023). CONCLUSION The elevated serum uric acid level may be independently and significantly associated with the presence and progression of carotid atherosclerosis in Chinese individuals aged 75 years or older.

Abstract
OBJECTIVES To determine the ability of Coronary Artery Calcification Score (CACS) and carotid ultrasonography (US) to detect high cardiovascular (CV) risk axial spondyloarthritis (ax-SpA) patients. METHODS CACS and carotid plaques were assessed in 66 consecutive ax-SpA patients (51 fulfilling criteria for ankylosing spondylitis and 15 for non-radiological ax-SpA) without history of CV events. The Systematic Coronary Risk Evaluation (SCORE) calculated using total cholesterol (TC-SCORE) was assessed in 64 patients without diabetes mellitus or chronic kidney disease. RESULTS The mean age of the patients and the median disease duration since the onset of symptoms were 49.3 and 14.5 years. HLA-B27 was positive in 47 (75%) patients. CV risk was categorised according to the TC-SCORE as low (<1%; n=33), moderate (≥1% and<5%; n=30) and high/very high risk (≥5%; n=1). Most patients with low TC-SCORE (27/33; 82%) had normal CACS (zero), and only 1/33 had CACS >100. However, carotid plaques were observed in patients with CACS=0 (12/37; 32%) and CACS 1-100 (10/16; 62%). The sensitivity to detect high/very high CV risk using only the TC-SCORE was very low as the algorithm only detected 1/33 (3%) of patients with high/very high CV risk. Ten of 33 (30%) high/very high CV risk patients were identified using a chart TC-SCORE risk ≥5% plus the presence of CACS ≥100 in patients with moderate TC-SCORE. The replacement of CACS with carotid US identified a higher number of high/very high CV risk patients (22/33; 67%). CONCLUSIONS Carotid US is more sensitive than CACS for the detection of high CV risk in ax-SpA patients.

Abstract
OBJECTIVE Type 2 diabetes mellitus (T2DM) is known to be associated with increased cardiovascular risk. The aim of this study was therefore to investigate the independent effects of hyperglycaemia, hypoglycaemia, and glucose variability on microvascular and macrovascular disease in T2DM. METHODS Subjects with T2DM of <10 years duration and on stable antiglycaemic treatment underwent carotid intima-media thickness (CIMT), ankle-brachial index (ABI), albumin-creatinine ratio (ACR), and HbA1c measurement, as well as 72-hour continuous glucose monitoring. Macrovascular disease was defined as one or more of the following: history of ischaemic heart disease (IHD), cerebrovascular accident (CVA), ABI < 0.9, or abnormal CIMT. RESULTS The study population comprised 121 subjects with T2DM (89 males : 32 females). The mean age was 62.6 years, and the mean DM duration was 3.7 years. Macrovascular disease was present in 71 patients (58.7%). In multivariate logistic regression analysis, body surface area (BSA) (OR 18.88 (95% CI 2.20-156.69), p = 0.006) and duration of blood glucose (BG) < 3.9 mmol/L (OR 1.12 (95% CI 1.014-1.228), p = 0.024) were independent predictors of macrovascular disease. BSA (OR 12.6 (95% CI 1.70-93.54), p = 0.013) and duration of BG < 3.9 mmol/L (OR 1.09 (95% CI 1.003-1.187), p = 0.041) were independent predictors of abnormal CIMT. Area under the curve for BG > 7.8 mmol/L (β = 15.83, p = 0.005) was the sole independent predictor of albuminuria in generalised linear regression. CONCLUSIONS This study demonstrates that hypoglycaemia is associated with the occurrence of atherosclerotic disease while hyperglycaemia is associated with microvascular disease in a Caucasian population with T2DM of recent duration.

Abstract
We performed a meta-analysis of population studies reporting data on carotid intima-media thickness and plaque in patients with and without metabolic syndrome (MetS) to provide a new piece of information on the relationship of MetS with both phenotypes of vascular damage. The Ovid MEDLINE, PubMed, and Cochrane CENTRAL databases were searched without time restriction up to December 31, 2016. Overall, 19 696 patients (22.2% with MetS) were included in eight studies. Common carotid intima-media thickness was greater in patients with MetS compared with those without it (788 ± 47 μm vs 727 ± 44 μm), with a standard means difference of 0.28 ± 0.06 (P = .00003). Increased intima-media thickness in patients with MetS was paralleled by a higher prevalence of plaques. The present meta-analysis shows that MetS is associated with both ultrasonographic phenotypes of carotid damage. This finding is consistent with the view of MetS as a cluster of hemodynamic and nonhemodynamic factors promoting vascular hypertrophy and plaque.

Abstract
Aortic atheroma is a known cause of ischemic stroke. However, it is unclear whether ischemic stroke is caused by emboli from aortic atheroma or by accompanying atherosclerosis. In this study, we evaluated lesion patterns of patients with complex aortic plaque (CAP) to assume the underlying pathophysiology. Acute ischemic stroke patients who underwent transesophageal echocardiography were included. CAP was defined as a plaque in the proximal aorta ≥ 4 mm thick or with a mobile component. The diffusion-weighted imaging lesion patterns of patients with CAP were compared to those with large arterial atherosclerosis (LAA) or cardioembolism (CE). A total of 64 CAP patients, 127 LAA patients, and 80 CE patients were included. Small cortical pattern was more common in the CAP group (45.3%) than in the LAA (7.9%, p < 0.001) or the CE group (23.8%, p = 0.018). A large cortical pattern was more common in the CE group than in the CAP group (p < 0.001), whereas subcortical only pattern tended to be more common in the CAP group than in the CE group (p = 0.057). In multinominal analysis, the CAP group was more likely to have a small cortical lesion than the LAA group [odds ratio (OR) 14.63; 95% confidence interval (CI) 4.67-45.85] or the CE (OR 3.69, 95% CI 1.19-11.39) group. In conclusion, patients with CAP frequently had small cortical lesions or subcortical single lesion. These findings imply that ischemic stroke in aortic atheroma patients is associated with either small emboli or small artery disease.

Abstract
We report the first case of a transtympanic iatrogenic internal carotid artery (ICA) pseudoaneurysm diagnosed in a 4-year-old child following a myringotomy. An endovascular treatment with a covered-stent was decided; spontaneous thrombosis was found during the therapeutic arteriography, and the procedure was aborted. Otoscopy and computed tomography (CT) scan monitoring showed a prolonged thrombosis and the disappearance of the pseudoaneurysm 18months after the diagnostic arteriography. Based on literature review, endovascular techniques seem to be preferred to the surgical approach for treatment of intrapetrous ICA pseudoaneurysm, however clinical and CT scan monitoring may also be a valid option.

Abstract
Isolated internal carotid artery (ICA) thrombus in the absence of underlying atherosclerotic disease is a rare entity. We report a case of a patient presenting with right arm weakness, slurred speech, and altered mental status in the setting of acute on chronic pancreatitis. The patient was found to have scattered left cerebral hemisphere cortical infarctions, and catheter angiography confirmed the presence of intraluminal left ICA thrombus, with no evidence of atherosclerotic disease in the cervical or intracranial vasculature. Further workup also demonstrated the presence of anemia of chronic disease. The patient was initiated on anticoagulation, and follow-up imaging demonstrated a complete resolution of the left ICA thrombus. In the reported case, coagulopathy in the setting of acute on chronic pancreatitis was presumably the primary etiology. Anemia of chronic disease, related to a proinflammatory state, may also play a contributory role.

Abstract
BACKGROUND Reversal of flow in the vertebral artery (RFVA) is an uncommon finding on cerebrovascular duplex ultrasound examination. The clinical significance of RFVA and the natural history of patients presenting with it are poorly understood. Our objective was to better characterize the symptoms and outcomes of patients presenting with RFVA. METHODS A retrospective review was performed of all cerebrovascular duplex ultrasound studies performed at our institution between January 2010 and January 2016 (N = 2927 patients). Individuals with RFVA in one or both vertebral arteries were included in the analysis. RESULTS Seventy-four patients (74/2927 patients [2.5%]) with RFVA were identified. Half of the patients were male. Mean age at the time of the first ultrasound study demonstrating RFVA was 71 years (range, 27-92 years); 78% of patients had hypertension, 28% were diabetic, and 66% were current or former smokers. Indications for the ultrasound examination were as follows: 44% screening/asymptomatic, 7% anterior circulation symptoms, 20% posterior circulation symptoms, 28% follow-up studies after cerebrovascular intervention, and 5% upper extremity symptoms. At the time of the initial ultrasound examination, 21 patients (28%) had evidence of a prior carotid intervention (carotid endarterectomy or carotid stenting), 21 patients had evidence of moderate (50%-79%) carotid artery stenosis (CAS) in at least one carotid artery, and 12 patients (16%) had evidence of severe (>80%) CAS. Of the 15 patients presenting with posterior circulation symptoms, 11 (73%) had evidence of concomitant CAS. In contrast, 22 of the 59 patients (37%) without posterior circulation symptoms had duplex ultrasound findings of CAS (P = .01). The mean duration of follow-up was 28 ± 22 months. Follow-up data were available for 63 patients (85%), including the 15 patients who presented with posterior circulation symptoms. Of these 15 patients, 5 underwent subclavian artery revascularization, including balloon angioplasty and stenting in 4 patients and open/hybrid revascularization in 1 patient. Five individuals were awaiting intervention. Three patients underwent carotid endarterectomy for CAS, with resultant improvement in posterior circulation symptoms. Finally, one patient was deemed too high risk for intervention, and one patient was found to have an alternative cause for symptoms. The remaining 59 patients continued to be asymptomatic during follow-up. One patient progressed to vertebral artery occlusion, and six patients had progression of CAS. CONCLUSIONS Symptomatic RFVA responds well to intervention, including subclavian artery stenting and carotid intervention in patients with CAS. The majority of patients with this finding are asymptomatic at the time of presentation. Although progression of vertebral artery disease is rare, these patients may benefit from monitoring for progression of CAS with surveillance ultrasound.

Abstract
Objectives Previous studies have demonstrated an association between snoring and carotid disease independent of sleep apnea. The aim of this study was to quantify the association between self-reported snoring and high-risk carotid plaque features on magnetic resonance imaging (MRI) that predict stroke. Study Design Cross-sectional. Setting Tertiary care university hospital and affiliated county hospital. Methods We surveyed 133 subjects with asymptomatic carotid artery disease that had been previously evaluated with high-resolution MRI. The survey captured data on self-reported snoring (exposure) and covariates (age, sex, body mass index, and sleep apnea via the STOP-Bang questionnaire). A subset of patients underwent home sleep apnea testing. High-risk carotid plaque features were identified on the high-resolution MRI and included thin/ruptured fibrous cap and intraplaque hemorrhage (outcomes). We quantified the association between snoring and high-risk carotid plaque features with the chi-square test (unadjusted analysis) and multivariate logistic regression adjusting for the covariates. Results Of 133 subjects surveyed, 61 (46%) responded; 32 (52%) reported snoring. Significantly higher proportions of snorers than nonsnorers had a thin/ruptured fibrous cap (56% vs 25%, P = .01) and intraplaque hemorrhage (63% vs 29%, P < .01). In multivariate analysis, snoring was associated with thin/ruptured fibrous cap (odds ratio, 4.4; 95% CI, 1.1-16.6; P = .04) and intraplaque hemorrhage (odds ratio, 8.2; 95% CI, 2.1-31.6; P < .01) after adjusting for age, sex, body mass index, and sleep apnea. Conclusion This pilot study suggests a significant independent association between snoring and high-risk carotid plaque features on MRI. Further study is warranted to confirm these results in a larger cohort of subjects.

Abstract
INTRODUCTION Carotid blowout syndrome (CBS) is a life threatening complication associated with head and neck cancers (HNC) and its treatment. The mortality rate was reported to range from 3% to over 50% in the literature. Direct surgical repair of the ruptured internal carotid artery is often not technically possible due to the difficult anatomy and underlying poor co-morbid status. Endovascular techniques such as coil embolization and stent grafting offer an alternative to surgical ligation with better patient outcomes. METHODS We describe the successful use of an endovascular approach in a case of emergent rupture of the common carotid artery (CCA) with massive bleeding in a patient submitted to radiotheraphy for the treatment of a neck malignancy. RESULTS A 75-year-old man with a squamous cell carcinoma of the esophagus having undergone chemotherapy and radiotherapy, was admitted to the emergency room with haematemesis with approximately 1 hour of evolution. An angiogram revealed, in the right common carotid artery, contrast extravasation with a possible fistula communicating to the esophagus. A self-expandable covered stent was deployed in the right common carotid artery. Successful repair of the vessel was confirmed in the control angiogram. The patient was discharged 10 days later without neurological deficit or recurrent bleeding. Carotid blowout syndrome is one of the most complex bleeding complications that may occur in HNC patients. It is usually a life-threatening event and is accompanied with unexpectedly massive bleeding and high mortality/morbidity rates. Short and long term effects of radiation over arteries have been reported. Radiation can induce damage to the vasa vasorum of large arteries and it might lead to the rupture of arteries. In the HNC population with previous surgery or radiotherapy, a high index of suspicion must be maintained for CBS in patients presenting with any recent history of oral bleeding or haemorrhaging from an exposed neck wound. CONCLUSION Current evidence shows that there was no significant difference in technical and hemostatic outcomes between the reconstructive and deconstructive endovascular methods. Permanent vessel occlusion resulted in higher immediately cerebral ischemia and stent grafting induced the more potentially delayed complications, such as infection, rebleeding, and stent thrombosis. In the present case, the endovascular management of CBS of the common carotid artery had high technical success and allowed immediate haemostasis. It has been suggested that self-expanding stent-grafts are useful for the initial control of carotid bleeding but are associated with more delayed complications.

Adipokines as atherothrombotic risk factors in obese subjects: Associations with haemostatic markers and common carotid wall thickness. Nutr Metab Cardiovasc Dis 2017; 27:571-580. [PMID: 28428025 DOI: 10.1016/j.numecd.2017.02.007] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/10/2016] [Revised: 02/21/2017] [Accepted: 02/25/2017] [Indexed: 11/28/2022]
Abstract
BACKGROUND AND AIMS Some crucial associations between obesity-related altered adipokine levels and the main factors of atherosclerotic, atherothrombotic processes are not fully known. We analysed the relationships of classic adipokines, namely leptin, resistin, adiponectin, tumour necrosis factor-alpha (TNF-α), interleukin 6 (IL-6) with the markers of platelet activation, including mean platelet volume (MPV), platelet surface/soluble P-selectin, platelet-derived microparticles (PMPs), the parameters of coagulation abnormalities and common carotid intima-media thickness (IMT) in obese patients with or without atherosclerotic comorbidities in comparison to age- and sex-matched controls. METHODS AND RESULTS We enrolled 154 obese individuals, including 98 suffering from atherosclerotic concomitant conditions, 56 free of atherosclerotic comorbidities and 62 healthy controls. Plasma levels of leptin, resistin, adiponectin, TNF-α, IL-6, soluble P-selectin, and plasminogen activator inhibitor-1 antigen (PAI-1 ag) were analysed by ELISA. Platelet surface P-selectin and PMPs were measured by flow cytometry. IMT was detected by ultrasonography. Adipokines were closely associated with markers of platelet hyperactivity, hypercoagulability, hypofibrinolysis and IMT. Significant independent associations were found between leptin and platelet count (p < 0.0001), MPV (p = 0.019), PMPs (p < 0.0001), fibrinogen (p = 0.001), factor VIII (FVIII) activity (p = 0.035); adiponectin and PAI-1 ag (p = 0.035); resistin and soluble P-selectin (p = 0.002); TNF-α and PAI-1 ag (p < 0.0001); and IL-6 and fibrinogen (p = 0.011). Finally, leptin (p = 0.0005), adiponectin (p = 0.019), IL-6 (p = 0.001), MPV (p = 0.0003), PMP (p = 0.008), and FVIII activity (p = 0.043) were independent predictors of IMT. CONCLUSION Overall, we suggest that in obese subjects altered adipokine levels play a key role in common carotid atherosclerosis both directly and through haemostatic parameters.

Abstract
INTRODUCTION According to the "common soil" hypothesis, diabetic microangiopathy and macroangiopathy have a similar pathophysiological background. It has been well documented that carotid artery atherosclerosis in patients with type 2 diabetes is associated with cardiovascular complications; however, it remains unclear whether there is a similar association for microvascular complications. OBJECTIVES We investigated whether the carotid plaque score and the carotid intima-media thickness (IMT) are associated with macroangiopathic and microangiopathic complications of type 2 diabetes. PATIENTS AND METHODS We enrolled patients with type 2 diabetes and microvascular complications or overt macroangiopathy. A B‑mode carotid ultrasound was performed in all participants, and anthropometric parameters, hemoglobin A1c (HbA1c) levels, lipid profile, and smoking status were assessed. RESULTS The study included 73 patients (mean [SD] age, 63.6 [7.5] years; 36 men [49%]). The mean (SD) diabetes duration was 11.7 (8.1) years. Microvascular complications were observed in 32 patients (43.8%), and overt macroangiopathy, in 42 (57.5%). Hypertension was reported for 60 patients (82%); dyslipidemia, for 56 (77%); obesity, for 37 (51%); and smoking, for 10 (14%). A multivariate regression analysis showed that the carotid plaque score, but not carotid IMT, was significantly associated with dyslipidemia (P = 0.03) and microangiopathy (P = 0.01). CONCLUSIONS Our results indicate that, unlike carotid IMT, the carotid plaque score is independently associated with microangiopathic complications in type 2 diabetes. Patients with a high plaque score should receive special care and the most intensive treatment to stop progression of these complications.

Abstract
BACKGROUND Intracavernous internal carotid artery (ICICA) aneurysm secondary to pituitary infection is exceedingly rare. CASE DESCRIPTION We report an unusual case of a 63-year-old man who presented with acute left blepharoptosis and imaging findings of a pituitary infection. Interestingly, sudden onset of right blepharoptosis occurred after anti-infective therapy for 10 days. Digital subtraction angiography revealed a right ICICA aneurysm. After 6 months of follow-up visits, enlargement of the ICICA aneurysm was observed, and the endovascular technique of a low-profile visualized intraluminal support stent combined with 5 detachable coils was successfully performed to treat the ICICA aneurysm, with preservation of the internal carotid artery. CONCLUSION This rare case highlights a life-threatening complication of a pituitary infection. Moreover, enlargement of the infected ICICA aneurysm could not be relieved by conservative anti-infective therapy. Endovascular treatment may be an alternative therapy for an infected ICICA aneurysm.

Abstract
The aim of this study was to explore the associations and differences in influencing factors between alcoholic liver disease (ALD) coupled with Helicobacter pylori infection and atherosclerosis and to determine whether there is a "double hit phenomenon" in atherosclerosis patients with ALD and H. pylori infections. Included cases (n = 160) were categorized into 4 groups: 41 cases of ALD coupled with H. pylori infections (group A), 35 cases of H. pylori infections without ALD (group B), 37 cases of ALD without H. pylori infections (group C), and 47 normal control cases (group D). CIMT was significantly greater in group A than in groups B and D (P = 0.005 and P = 0.001, respectively). The GLM univariate analysis found that CIMT was significantly greater in group A than in groups B, C and D (P = 0.018, P = 0.001 and P = 0.009, respectively). We found that BMI and ALT, AST and ApoB levels were independent predictors of CIMT (P = 0.000, P = 0.000, P = 0.012 and P = 0.014, respectively). ALD coupled with H. pylori infection may result in significant CIMT thickening, but H. pylori infection without ALD and ALD without H. pylori infection does not, suggesting that a "double hit phenomenon" occurs. Additionally, BMI, and ALT, AST and ApoB levels were independent risk factors for increased CIMT.

Abstract
PURPOSE The aim of the present study was to investigate the association between plasma homocysteine (Hcy) levels and carotid, cardiac, and renal end-organ damage in newly diagnosed type 2 diabetes mellitus (T2DM) patients. METHODS Newly diagnosed normotensive T2DM patients (n = 390) were enrolled in this study. The patients were not taking any medications over the duration of the study. The left ventricular mass index (LVMI), carotid intima media thickness (CIMT), and creatinine levels and 24-h microalbuminuria were used to determine cardiac, carotid, and kidney end-organ diseases, respectively. RESULTS Using univariate logistic regression analysis; age, 24-h microalbuminuria, fasting blood glucose, CIMT, creatinine level, and LVMI were found to be significantly associated with the Hcy level. When those six variables were included in a multivariate regression model, CIMT, LVMI, and creatinine were found to be significantly associated with the Hcy level. We determined that an Hcy level >12.5 µmol/L was predictive of high LVMI, with a sensitivity of 70.1% and a specificity of 68%. An Hcy level >13.5 µmol/L was predictive of high CIMT, with a sensitivity of 67.5% and a specificity of 63.1%. CONCLUSION In this study, LVMI, CIMT, and creatinine level were positively correlated with the Hcy level. We believe that the Hcy level may be a useful predictor of end-organ damage, including cardiac, carotid, and renal diseases, in newly diagnosed T2DM patients.

Abstract
AIM The present paper is a selective review on the methodology and clinical significance of techniques to assess specifically endothelial function, carotid mechanics and renal vascular function, particularly in the light of vascular dysfunction in metabolic syndrome and type 2 diabetes. DATA SYNTHESIS Endothelial dysfunction appears to be earlier detectable in the microcirculation of patients with altered glucose metabolism, while it attains significance in the macrocirculation at more advanced disease stages. Smooth muscle cell dysfunction is now increasingly recognized to play a role both in the development of endothelial dysfunction and abnormal arterial distensibility. Furthermore, impaired glucose metabolism affects carotid mechanics through medial calcification, structural changes in extracellular matrix due to advanced glycation and modification of the collagen/elastin material stiffness. The assessment of renal vascular function by dynamic ultrasound or magnetic resonance imaging has recently emerged as an appealing target for identifying subtle vascular alterations responsible for the development of diabetic nephropathy. CONCLUSIONS Vascular dysfunction represents a major mechanism for the development of cardiovascular disease in patients with abnormal glucose metabolism. Hence, the currently available non-invasive techniques to assess early structural and vascular abnormalities merit recommendation in this population, although their predictive value and sensitivity to monitor treatment-induced changes have not yet been established and are still under investigation.

Abstract
Carotid-internal jugular venous fistula is one of the rarest presentations among victims of bomb blast injuries. Treatment of such fistula is open surgery with high mortality and morbidity. Endovascular treatment with covered stent seems to have an optimal result with low complications. We present a case report of a bomb blast victim having carotid-jugular venous fistula with hemodynamic compromise. The patient was successfully managed with endovascular graft stent. There was an optimal result with no immediate and long-term complications.

Abstract
Internal carotid artery pseudoaneurysm is an uncommon complication of retropharyngeal and parapharyngeal abscess in children. Treatment of the pseudoaneurysm has evolved in recent years from surgical ligation to endovascular techniques. Neurologic sequelae most commonly consist of Horner's syndrome with cerebral ischemia being uncommon. The clinical course of a 2-year-old boy with retropharyngeal abscess complicated by internal carotid artery pseudoaneurysm, is described and the literature is reviewed. A conventional angiogram confirmed the presence of a large pseudoaneurysm with no anterograde flow distal to the pseudoaneurysm and substantial collateral flow across the circle of Willis, with filling of the left anterior and middle cerebral arteries via the anterior and posterior communicating arteries. Endovascular occlusion resulted in nonfilling of the left internal carotid artery, pseudoaneurysm, and left internal jugular vein at the base of the skull. Following the procedure, the patient developed transient mild right hemiparesis associated with frontal lobe ischemia.

Abstract
AIMS To assess whether circulating 25-hydroxyvitamin D3 (25OHD) and mineral metabolism-related factors (serum phosphate, calcium, and parathormone) are associated with subclinical carotid atherosclerosis (SCA), defined as the presence of carotid atherosclerotic plaques (main study outcome), in patients with type 2 diabetes mellitus (T2DM) without kidney disease or previous cardiovascular disease. METHODS We undertook a post hoc analysis of a cross-sectional study in adults with T2DM in whom we evaluated SCA. A total of 303 subjects with T2DM were included. Clinical variables and carotid ultrasound imaging were obtained. RESULTS We found no association of 25OHD with the presence of SCA. However, calcium phosphate (CaP; mg2/dL2) product was positively associated with the presence of carotid plaques (ORadj = 1.078; 95% CI: 1.017-1.142). An inverse association was observed between higher levels of 25OHD (≥30 ng/mL versus <20 ng/mL concentrations) and common carotid intima-media thickness (cIMT; mm) (βadj ± SE = -0.055 ± 0.024). We conclude that the CaP product is independently associated with the presence of established subclinical carotid atherosclerosis in patients with T2DM.

Abstract
AIMS To quantify cardiovascular risk in persons with type-2 diabetes (DM) and established carotid atherosclerosis, without inducible myocardial ischemia by stress imaging. METHODS We selected clinically healthy DM and subjects without DM (nonDM, controls) with non-obstructive carotid atherosclerosis and without significant coronary artery disease (CAD) by stress echocardiography. Coronary flow velocity reserve (CFR) was assessed during stress echocardiography. In those with negative stress imaging, coronary artery calcium (CAC) assessment by computed tomography (CT) was proposed. Outcome at 180-day follow-up was performed by visits or telephone interview. RESULTS Total CAC was greater in DM (n=19) than in nonDM (n=19, CAC: 225±158 vs 78±65Agatston units, 156±161 vs 53±51 in the left anterior descendent artery, both p<0.05). Coronary stenosis burden was greater in DM than in nonDM, albeit <75% in all cases; CFR was lower in DM than nonDM (p<0.05). Mean age was slightly higher (69±6 vs 64±12, p>0.2), and male gender tended to be less frequent (63 vs 79%) with DM than with nonDM; all subjects showed dyslipidemia, and almost all had arterial hypertension. Based on CAC, a 10-year cardiovascular risk was 10-20% in 78% of the DM and in 28% of the non-DM, and was >20% in 11% of the DM but in none of the nonDM. A single non-fatal myocardial infarction was recorded within 180days from test, among DM. CONCLUSIONS Based on CAC, in the presence of non-obstructive carotid atherosclerosis, asymptomatic DM may show significantly higher CAD burden than nonDM even in the absence of inducible myocardial ischemia.

Abstract
BACKGROUND AND AIM Although subclinical hypothyroidism (SCH) is associated with cardiovascular risk, there is scarce data about subclinical atherosclerosis in subjects with SCH. We aimed to analyze the association between SCH and carotid intima-media thickness (IMT) using baseline data from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). METHODS AND RESULTS We included subjects with normal thyroid function (TSH: 0.4-4.0 mIU/l, and normal free thyroxine (FT4): 0.8-1.9 ng/dl) and SCH (TSH ≥ 4.0 mIU/l and normal FT4) evaluated for IMT in a cross-sectional analysis. We excluded individuals using medications that affect thyroid function and those with a history of cardiovascular disease. We performed logistic and linear regression models to evaluate the association with IMT (mean values and categorized at the 75th percentile) as a dependent variable and SCH as an independent variable, adjusted for other cardiovascular risk factors. From 8623 subjects (median age of 50 years; interquartile range: 44-57), 4624 (53.6%) were women, 8095 (93.9%) were euthyroid, and 528 (6.1%) had SCH. Groups varied in age, body mass index, Framingham risk score, Homeostasis Model Assessment for Insulin Resistance (HOMA-IR), C-reactive protein, as well as, IMT, that were all higher in SCH compared to euthyroid participants. SCH is associated with IMT as a continuous variable (β = 0.010, P = 0.036) and IMT >75th percentile: OR = 1.30 (95% CI = 1.06-1.59) in logistic models. CONCLUSION Individuals with SCH presented higher IMT compared with euthyroid subjects, even after adjustment for potential confounders. IMT was independently associated with SCH in the baseline of the ELSA-Brasil study.

Abstract
BACKGROUND The prognostic importance of preclinical markers of atherosclerosis and their interrelationship are inconclusive. In this study interrelationship between different methods investigating endothelial function and intima media thickness (IMT) was investigated in patients with polycystic ovary syndrome (PCOS). METHODS Endothelial function was assessed by endothelium-dependent flow-mediated dilation (FMD), nitrate-mediated dilation (NMD), low-flow-mediated constriction (L-FMC) and peripheral arterial tonometry (PAT). Arterial stiffness was determined by pulse wave velocity (PWV) and the Augmentation Index (AI). The IMT of carotid arteries was measured. RESULTS Twenty-eight obese women were recruited with the diagnosis of PCOS, mean age 27±7.2 years and Body Mass Index 38.8±6.3 kg/m2. A relationship between FMD and NMD (r=0.44, P=0.02) was shown. FMD as well as NMD of the brachial artery were not correlated with L-FMC or PAT. The AI and PWV, indicators of arterial stiffness were not interrelated with FMD, and there was no significant interrelationship between IMT and FMD or NMD. The AI was related only to IMT (r=0.45, P=0.30). CONCLUSIONS The relationship between available methods for evaluation of endothelial function/dysfunction is weak in PCOS. This indicates that different methods investigate different mechanisms and various sections of the circulatory system.

Abstract
The objective of this prospective observational study was to establish the prevalence of carotid atherosclerosis in an asymptomatic diabetic population and to determine predictive factors for a screening optimization. A total of 300 consecutive type-2 diabetic subjects (166 males, 134 females) underwent a physical examination and duplex carotid scanning. Patients with a recent cerebrovascular event (±6 weeks) or previous carotid surgery were excluded. The prevalence of carotid stenosis ≥60% or occlusion was 4.7%; the prevalence of carotid atherosclerosis was 68.3%. Risk factors for stenosis ≤60% or occlusion were the presence of diabetic retinopathy (OR: 3.62; 95% CI: 1.12-11.73), ankle-brachial index (ABI) <0.85 (OR: 3.94; 95% CI: 1.21-12.84) and a personal history of neurological disorders (OR: 4.54; 95% CI: 1.16-17.81). Being female was a protective factor (OR: 0.09; 95% CI: 0.01-0.78). The two factors in the analysis limited to the male population were an ABI < 0.85 (OR: 3.66; 95% CI: 1.04-12.84) and a personal history of coronary heart disease (OR: 3.34; 95% CI: 1.01-11.01). If male diabetics without either of these two factors are excluded, the negative predictive value for carotid stenosis is 96.6%. In conclusion, the prevalence of atherosclerotic carotid disease in diabetic patients is high. In these patients, the probability of finding >60% stenosis is highest among men with a history of coronary heart disease or an ABI <0.85.

Abstract
OBJECTIVES To determine if the use of carotid ultrasonography (US) may improve the cardiovascular (CV) risk stratification in patients with ankylosing spondylitis (AS). METHODS A set of 127 consecutive patients without history of CV events, diabetes mellitus or chronic kidney disease that fulfilled definitions for AS according to the 1984 modified New York criteria were recruited to assess carotid intima-media thickness and presence of plaques. CV risk was calculated according to the systematic coronary risk evaluation (SCORE), the Framingham Risk Score (FRS) and the Reynolds Risk Score (RRS). RESULTS Men outnumbered women (61.4%). The mean±SD age at the time of the study was 44.5±11.6 years. The median (interquartile range-IQR) disease duration was 13 (7-22) years. The median (IQR) BASDAI at the time of the study was 3.65 (1.7- 4.9). HLA-B-27 was positive in 77.2%, and syndesmophytes were present in 38.9%. Carotid plaques were found in 43 (33.9%). Regardless of the algorithm used for CV risk stratification, more than 50% of the patients classified as having moderate CV risk had carotid plaques. Moreover, 20.8%, 24.6% and 53.3% of AS that fulfilled the category of low CV risk according to the total cholesterol (TC)-SCORE, FRS and RRS, respectively had carotid plaques. A model that included patients with a chart TC-SCORE ≥5% or TC-SCORE ≥1% <5% plus carotid plaques or TC-SCORE <1% and CRP >3 mg/L at diagnosis plus syndesmophytes and carotid plaques or TC-SCORE <1% and CRP >3 mg/L at diagnosis plus extraarticular manifestations plus carotid plaques yielded the highest sensitivity (93.0%) for high/very high CV risk in these patients. The presence of syndesmophytes was associated with increased risk of carotid plaques in AS that fulfilled definitions for low CV risk according to the TC-SCORE (OR 8.75 [95% CI 2.11-36.40]; p=0.002). CONCLUSIONS Our results support the use of carotid US in the assessment of CV risk in patients with AS.

Abstract
OBJECTIVE Osteoprotegerin (OPG) is considered an important biomarker in cardiovascular (CV) disease. CV disease is the most common cause of mortality in patients with rheumatoid arthritis (RA), a consequence of accelerated atherosclerosis. The present study aimed to evaluate the relationship of serum OPG levels to arterial stiffness, carotid intima-media thickness (CIMT), and clinical and laboratory indices in RA patients. PATIENTS AND METHODS Included in the study were 68 RA patients with no history or signs of CV disease and 48 healthy subjects Disease activity was assessed by the 28-joint disease activity score (DAS28) in RA patients. Serum OPG level was measured using enzyme-linked immunosorbent assay (ELISA). Carotid femoral pulse wave velocity (PWV) was measured as an index of arterial stiffness and CIMT was evaluated by carotid ultrasonography. RESULTS The mean serum OPG level was significantly higher in RA patients than controls (p < 0.001). Mean PWV and CIMT were also significantly increased in RA patients compared to controls (both p < 0.001). In RA patients, serum OPG level was significantly correlated with PWV and CIMT, as well as rheumatoid factor (RF) and anti-cyclic citrullinated peptide (anti-CCP) antibody; but not with DAS28, high-sensitivity C-reactive protein (hsCRP), or erythrocyte sedimentation rate. CONCLUSION Serum OPG levels were increased and correlated with CIMT and PWV in RA patients. In addition to PWV and CIMT, OPG may be a useful biomarker for CV risk management in RA patients.

Abstract
Persistent trigeminal artery (PTA), also called primitive trigeminal artery, represents the most common embryonic remnant of fetal circulation in adulthood, (only after fetal pattern of posterior communicating artery [PComA]) with an estimated incidence of between 0.1% and 0.76%. The permanence of this fetal pattern constitutes an incidental finding in most cases, however, may be associated with aneurysms, arteriovenous malformations, trigeminal neuralgia, and other types of fetal circulation persistency. A patient with giant aneurysm in the communicating segment of the right internal carotid artery, associated with the presence of PTA and fetal pattern of PComA, also on the right side is reported.

Abstract
Background. Previous experiments have studied separately the development of either cardiac or aortic fibrosis and stiffness in aldosterone (Aldo)-salt hypertensive rats. Our aim was to determine in vivo the effects of Aldo and the Aldo receptor antagonist eplerenone (Epl) on simultaneous changes in cardiac and arterial structure and function and their interactions. Methods and Results. Aldo was administered in uninephrectomised Sprague-Dawley rats receiving a high-salt diet from 8 to 12 weeks of age. Three groups of Aldo-salt rats were treated with 1 to 100 mg/kg-1. d-1 Epl by gavage. Arterial elasticity was measured by elastic modulus (Einc)-wall stress curves using medial cross-sectional area (MCSA). The cardiac and arterial walls were analysed by histomorphometry (elastin and collagen), immunohistochemistry (EIIIA fibronectin, Fn), and Northern blot (collagens I and III). Aldo caused increased systolic blood pressure (SBP), carotid Einc, MCSA, and EIIIA Fn with no change in wall stress or elastin and collagen densities. No difference in collagen mRNA levels was detected between groups. During the same period, cardiac mass and collagen mRNA and protein levels increased markedly in the myocardial tissue. Epl normalised collagen in the myocardium, Eincwall stress curves, MCSA, and EIIIA Fn in Aldo rats. These dose-dependent effects were not accompanied by a consistent reduction in SBP and cardiac mass. Conclusions. In exogenous hyperaldosteronism in the rat, Aldo causes independently myocardial collagen and arterial Fn accumulation, the latter being responsible for increased intrinsic carotid stiffness. Epl prevents both cardiac and arterial effects but does not reduce consistently SBP.

Abstract
BACKGROUND This study aimed to determine the relationship of statin therapy and cardiovascular risk factors to changes in atherosclerosis in the carotid artery. METHODS AND RESULTS Carotid magnetic resonance imaging was used to evaluate 106 hyperlipidemic participants at baseline and after 12 months of 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitor (statin) treatment. Multivariable logistic regression was used to determine factors associated with progression (change in carotid wall volume >0) or regression (change ≤0) of carotid atherosclerosis. Computed tomography coronary calcium scores were obtained at baseline for all participants. The median age was 65 years (interquartile range 60-69 years), and 63% of the participants were male. Body mass index >30, elevated C-reactive protein, and hypertension were associated with increased carotid wall volume (obesity: odds ratio for progression 4.6, 95% CI 1.8-12.4, P<0.01; C-reactive protein: odds ratio for progression 2.56, 95% CI 1.17-5.73, P=0.02; hypertension: odds ratio 2.4, 95% CI 1.1-5.3, P<0.05). Higher statin dose was associated with regression of carotid wall volume (P<0.05). In multivariable analysis, obesity remained associated with progression (P<0.01), whereas statin use remained associated with regression (P<0.05). Change in atheroma volume in obese participants was +4.8% versus -4.2% in nonobese participants (P<0.05) despite greater low-density lipoprotein cholesterol reduction in obese participants. CONCLUSIONS In a population with hyperlipidemia, obese patients showed atheroma progression despite optimized statin therapy. CLINICAL TRIAL REGISTRATION URL: http://www.clinicaltrials.gov.
