Abstract Introduction: Metabolic syndrome is one of the important risk factors in increasing the risk of cardiovascular disease. Recent studies have shown that increasing the thickness of the intima-medial layer of the carotid artery can be a risk factor associated with metabolic syndrome. Methods: This was a cross-sectional analytical study. All individuals underwent ultrasound of the carotid arteries. In the presence of stenosis, the stenosis caused by the plaque by North American symptomatic carotid endarterectomy trial (NASCET) was considered as a decrease in the diameter of the lumen compared to the diameter of the normal lumbar distal lobe and was expressed as a percentage. Statistical analysis of chi-square tests, independent t-test, ANOVA, and regression analysis were performed. Results: This study was performed on 112 male pilots (average age of 41.3 years, average flight time 2435 hours). There was no statistically significant relationship between the mean thickness of intima media carotid and metabolic syndrome (no versus with metabolic syndrome: 0.62 versus 0.64 mm p = 0.355). The average thickness of the intima media carotid was significantly statistically different between the three groups of flight types (transport aircraft: 01.61 against fighter: 0.70 and helicopter: 0.59 mm p = 0.004). There is also a significant correlation between flight time and carotid thickness (p = 0.001, r = 0.380). In addition, there was a significant correlation between the age of the pilots and the thickness of the carotid artery (p = 0.001, r = 0.033) as well as the age of the pilots and the flight time (p = 0.001, r = 0.713). Conclusion: Based on the results, there was no significant relationship between carotid thickness and metabolic syndrome and metabolic syndrome components in the studied pilots.

ObjectivesTo describe a well-established marker of cardiovascular risk, carotid intima–media thickness (IMT) and related measures (artery distensibility and elasticity) in children aged 11–12 years old and mid-life adults, and examine associations within parent–child dyads.DesignCross-sectional study (Child Health CheckPoint), nested within a prospective cohort study, the Longitudinal Study of Australian Children (LSAC).SettingAssessment centres in seven Australian major cities and eight selected regional towns, February 2015 to March 2016.ParticipantsOf all participating CheckPoint families (n=1874), 1489 children (50.0% girls) and 1476 parents (86.8% mothers) with carotid IMT data were included. Survey weights and methods were applied to account for LSAC’s complex sample design and clustering within postcodes and strata.Outcome measuresUltrasound of the right carotid artery was performed using standardised protocols. Primary outcomes were mean and maximum far-wall carotid IMT, quantified using semiautomated edge detection software. Secondary outcomes were carotid artery distensibility and elasticity. Pearson’s correlation coefficients and multivariable linear regression models were used to assess parent–child concordance. Random effects modelling on a subset of ultrasounds (with repeated measurements) was used to assess reliability of the child carotid IMT measure.ResultsThe average mean and maximum child carotid IMT were 0.50 mm (SD 0.06) and 0.58 mm (SD 0.05), respectively. In adults, average mean and maximum carotid IMT were 0.57 mm (SD 0.07) and 0.66 mm (SD 0.10), respectively. Mother–child correlations for mean and maximum carotid IMT were 0.12 (95% CI 0.05 to 0.23) and 0.10 (95% CI 0.03 to 0.21), respectively. For carotid artery distensibility and elasticity, mother–child correlations were 0.19 (95% CI 0.10 to 0.25) and 0.11 (95% CI 0.02 to 0.18), respectively. There was no strong evidence of father–child correlation in any measure.ConclusionsWe provide Australian values for carotid vascular measures and report a modest mother–child concordance. Both genetic and environmental exposures are likely to contribute to carotid IMT.

AbstractThere are two points of view on the interplay between carotid artery disease and diabetes mellitus: Diabetes mellitus has been recognized as one of the main determinants for the presence and progression of asymptomatic and symptomatic carotid artery disease; and carotid intima-media thickness has been defined as a useful tool for risk stratification of this population.Hyperglycaemia, duration of diabetes, arterial hypertension, cholesterol and inflammatory markers have previously been determined as independent factors for carotid atherosclerosis in diabetes, and aging as its predictor in this population by our own results. This paper focuses on the particularities of risk factors in diabetic patients (especially in type 2) and evidence-based guidelines for the management and risk reduction of these patients with stroke and/or carotid artery disease.At present, carotid ultrasound is recommended in diabetic patients with cerebrovascular symptoms. Since the prevalence of diabetes increases constantly, we attempt to address refreshment of criteria for screening of carotid artery disease in the diabetic population. It could be recommended for diabetic patients with at least one more risk factors and for diabetic patients above 60 years of age.

Background: Metabolic syndrome and its individual criteria pose a risk for atherosclerosis and cardiovascular disease (CVD). Carotid intima media thickness (CIMT) is a well-known marker of subclinical atherosclerosis. This study was aimed to assess CIMT in patients with metabolic syndrome.Methods: This one year cross-sectional study was conducted in the Department of Medicine, KLES Dr. Prabhakar Kore Hospital and Medical Research Centre, Belagavi from January 2016 to December 2016. A total of 100 patients diagnosed to have metabolic syndrome based on national cholesterol education program adult treatment panel III (NCEP ATP III) criteria were studied. All the patients were subjected to carotid B mode ultrasonography.Results: The most common age group was 51 to 60years (29%). Out of 100 individuals who were diagnosed to have metabolic syndrome, 60% had five criteria, 29% had four criteria and 3% had three criteria. Most of the of the individuals (61.00%) had normal (≤0.10cms) CIMT while high (>0.10cm) levels were noted in 39.00% of the individuals. The mean CIMT was noted as 0.13±0.16cms. The mean SBP (150.15±10.39 vs 142.98±20.09mmHg; p=0.042), DBP (94.51±6.53 vs 90.16±9.91 mmHg; p=0.017), total cholesterol levels (243.53±65.74 vs 195.95±29.8 mg/dL; p<0.001) and triglyceride levels (221.07±48.44 vs 180.85±24.74mg/dL; p <0.001) were noted in individuals with raised CIMT compared to individuals with normal CIMT. Majority of the individuals had abnormal HDL (93.00%) and 41.94% of the individuals with abnormal HDL had raised CIMT (p=0.027).Conclusions: Some individuals with metabolic syndrome are likely to have raised CIMT. The rise in CIMT among the patients with metabolic syndrome is associated with raised SBP, DBP, abnormal HDL (specifically in males), total cholesterol and triglycerides.

Abstract Background Increased waist circumference (WC) is one of the cardiovascular disease (CVD) risk factors used to predict cardiovascular events. Waist circumference cut-off values for predicting metabolic syndrome and other cardiovascular risks have been previously studied. Carotid intima-media thickness (CIMT) is one of the cardiovascular risk factor recently described and reported to be suitable as it is a direct measurement of vascular quality. Hence the aim of the present study was to determine the optimal WC cut-off point for the prediction of subclinical CVD. Methods The study was a cross-sectional study using quantitative methods, conducted among 1318 adults aged between 40 and 60 years old, residing in a rural Black population in Limpopo province. Carotid Intima-Media Thickness measurements were performed using a LOGIQ ultrasound system (GE Healthcare, CT, USA). Waist Circumference (WC) (cm) was measured to the nearest 0.1 cm. Bivariate correlation, logistic regression and receiver operating characteristic were analysed using the statistical package for social sciences version 26.0 software. Results Among the total population, 69% were women and 31% men with a mean age of 53 ± 7 years. Among women, WC at a cut-off value of 95 cm gave the highest sensitivity of 57%, the specificity of 55% and an area under the curve (AUC) of 0.588. In men, an optimum WC cut-off point of 82 cm yielded the highest sensitivity and specificity at 72% and 70% respectively, with an AUC of 0.767 p < 0.001. Conclusion The traditional waist circumference cut-off points (94 cm for women and 80 cm for men) that are currently used for the diagnosis of metabolic syndrome might not be suitable in the prediction of an increased CIMT.

Oxidative stress is the major cause of atherosclerosis and cardiovascular diseases. This cross-sectional study is aimed at determining if parallel serum markers of oxidative stress are related to carotid intima-media thickness (IMT). We enrolled 134 participants with varied metabolic syndrome (Met-S) scores (zero, n=21; one, n=19; two, n=27; three, n=26; four, n=25; five, n=16). Biochemical profiles and potential oxidative stress biomarkers malondialdehyde (MDA) and uric acid were measured in fasting plasma. We found that carotid IMT positively correlated with both MDA and uric acid levels. Multivariate analysis revealed that both MDA (p<0.05) and uric acid (p<0.01) levels were significantly associated with carotid IMT in participants whose Met-S scores were ≥1 or ≥2. However, only uric acid (p<0.01) levels were positively associated with carotid IMT in patients with metabolic syndrome. Linear regression model analysis revealed that the prediction accuracies for carotid IMT from MDA combined with uric acid and from a combination of MDA, uric acid, and Met-S score were 0.176 and 0.237, respectively. These were better than the predication accuracies from MDA (r2=0.075) and uric acid (r2=0.148) individually. These results suggest that measuring uric acid levels along with MDA biomarkers and Met-S scores may be a promising step in the development of an effective model for monitoring the severity of carotid IMT and atherosclerosis in the patients with metabolic syndrome.

Abstract Backrgound: To estimate the accuracy of metabolic syndrome definitions for detecting Carotid Intima-Media thickness (CIMT) in Peruvian type 2 diabetes mellitus (T2DM) subjects without cardiovascular events.Methods: We performed a cross-sectional evaluation of T2DM subjects from the endocrinology service of two reference health centers without stroke or coronary disease. . Bilateral carotid intima-media thickness was measure by B mode ultrasound one only operator. We performed four definitions of Metabolic Syndrome; 1. Cholesterol Education Program Adult Treatment Panel III (ATP III), 2. Harmonized criteria; 3. Gurka's Metabolic syndrome severity score (MSSS) formula. 4. Non-glucose modified MSSS. We calculated the area under the receiver operator curve (AUROC) for detecting increased CIMT (≥ 0.86 mm) between metabolic syndrome definitions. Results: We included 184 subjects with T2DM, 29% were men with a mean age of 61.5 ± 10.5 years old. Median diabetes time was 10.8 years (IQR 4.8 to 19.4), and 26.8% achieved HbA1c goals. Non-glucose modified MSSS was the only definition significantly correlated with elevated CIMT (r = 0.19; p<0.01), and it showed the best accuracy for predicting elevated CIMT (AUC: 0.61, CI95%: 0.52-0.70). Adjusting for age, sex, and HbA1c, each point increase in the non-glucose MSSS Z score, the risk of altered CIMT increases by 59% RP 1.59 (CI 95% 1.09 - 2.35; p=0.017). Conclusions: Non-glucose modified MSSS had a weak accuracy for elevated CIMT and was the best compared to ATP III, harmonized, and original MSSS. Further research on no MS-factors is required to predict better elevated CIMT.

Objective: This study investigated the association of metabolic syndrome (MS) and its components with cardiac, macro-, and micro-circulatory abnormalities in an elderly Chinese population.Methods: This cross-sectional study was conducted using data for 1,958 participants from the Northern Shanghai Study aged over 65 years without a history of cardiovascular disease. MS was defined according to the National Cholesterol Education Program Adult Treatment Panel III in 2005 (NCEPIII 2005). Asymptomatic cardiovascular impairment parameters, including the left ventricle mass index (LVMI), peak transmitral pulsed Doppler velocity/early diastolic tissue Doppler velocity (E/Ea), carotid-femoral pulse wave velocity (cf-PWV), ankle-brachial index (ABI), carotid intima-media thickness (CIMT), arterial plaque, and urinary albumin–creatinine rate (UACR), were evaluated.Results: LVMI, E/Ea, cf-PWV, and the proportion of UACR &gt; 30 mg/g exhibited increasing trends while ABI exhibited a decreasing trend according to the number of MS components (all p for trend &lt; 0.01). Logistic regression analysis revealed that MS was significantly associated with LV hypertrophy (LVH), LV diastolic dysfunction, arteriosclerosis, and microalbuminuria (all p &lt; 0.001). Central obesity and high blood pressure were associated with all cardiovascular abnormalities (all p &lt; 0.05), whereas elevated plasma glucose was associated with arteriosclerosis and microalbuminuria (both p &lt; 0.001). In addition, high triglyceride levels were associated with microalbuminuria (p &lt; 0.05).Conclusions: MS is significantly associated with cardiac, macro-, and micro-circulatory abnormalities in elderly Chinese. Moreover, the presence of individual MS components may have specific prognostic significance.
