Background: Bariatric surgery is a treatment option for patients with severe obesity and improves parameters of cardiovascular and/or metabolic disease. Carotid intima media thickness (C-IMT) is a surrogate measure of subclinical atherosclerosis. Previous studies showed short to mid-term arrest and even regression of C‑IMT progression following bariatric surgery. We aimed to investigate the long-term effect of weight loss on C‑IMT progression 10 years after bariatric surgery in comparison to a population-based control cohort., Methods: In total, 21 eligible patients were examined preoperatively, at 5 and 10 years after bariatric surgery. Anthropometric parameters, plasma triglycerides, total cholesterol, high-density lipoprotein cholesterol (HDL-C), insulin, and glucose were assessed at all three study visits. C‑IMT was measured via B‑mode scans of the common carotid artery. C‑IMT progression was measured in an age-matched and BMI-matched cohort selected from the population-based Bruneck study to compare with changes in C‑IMT progression after bariatric surgery., Results: C‑IMT remained stable over the 10-year observation period after bariatric surgery. The control cohort showed a significant C‑IMT progression over 10 years. The difference in C‑IMT progression over 10 years was significant (p < 0.01) between both cohorts., Conclusion: Weight loss induced by bariatric surgery halts the natural progression of C‑IMT over a 10-year observation period., (© 2022.

Background: Very few studies have reported on association of postprandial lipids and endothelial dysfunction among patients with diabetes. Whether endothelial dysfunction particularly postprandial FMD is worse in patients with T2DM with macrovascular disease compared to those without and whether this difference is related to postprandial hypertriglyceridemia (PPHTg) is unclear. Therefore, present study was aimed to assess the relationship between PPHTg and endothelial function in patients with T2DM with and without macrovascular disease., Method: Endothelial dysfunction by FMD and CIMT were compared in patients with T2DM with and without macrovascular disease (n = 13 each group) and 13 age, sex and BMI matched healthy individuals after an oral fat challenge., Results: There was significant postprandial deterioration of FMD 4-hr after fat challenge in patients with diabetes (P < 0.001) as well as healthy individuals (P = 0.004). Patients with diabetes with macrovascular disease had significantly lower fasting (5.7 ± 6.1% vs. 22.7 ± 10.0% and vs. 24.7 ± 5.3%) as well as postprandial (4-hr) (3.1 ± 5.0% vs. 15.3 ± 8.1% and vs. 15.4 ± 5.7%) FMD compared to other two groups. Fasting, postprandial as well as change in FMD and CIMT in patients with diabetes correlated significantly with fasting as well as postprandial triglycerides with stronger correlation in those with macrovascular disease., Conclusion: Study found significant endothelial dysfunction by FMD that shows substantial further deterioration postprandially following high fat meal in patients with diabetes with macrovascular disease compared to patients with diabetes without macrovascular disease and healthy individuals. Study also indicates that PPHTg is a contributor to endothelial dysfunction. However, more studies are required to corroborate these findings., Competing Interests: Declaration of competing interest I, on behalf of authors whose names are listed in the manuscript certify that there is no conflict of interest whatsoever associated with this manuscript., (Copyright © 2021 Diabetes India.

Background: Early life factors may predispose an offspring to cardiovascular disease in later life; relevance of these associations may extend to ‟healthy" people in Western populations. We examined the prospective associations between early life factors and adult carotid intima-media thickness (IMT), a surrogate marker of atherosclerosis, in a healthy German population., Methods: We studied term participants (n = 265) of the DONALD Study, with bilateral sonographic measurements of IMT (4-8 measurements on both left and right carotid artery) at age 18-40 years and prospectively collected data on early life factors (maternal and paternal age at child birth, birth weight, gestational weight gain and full breastfeeding (>17weeks). Mean IMT values were averaged from mean values of both sides. Associations between early life factors and adult IMT were analyzed using multivariable linear regression models with adjustment for potential confounders., Results: Adult mean IMT was 0.56mm, SD 0.03, (range: 0.41 mm-0.78 mm). Maternal age at child birth was of relevance for adult IMT, which was sex specific: Advanced maternal age at child birth was associated with an increased adult IMT among female offspring only (β 0.03, SE 0.009 mm/decade, P = 0.003), this was not affected by adult waist circumference, BMI or blood pressure. Other early life factors were not relevant for IMT levels in males and females., Conclusion: This study suggests that advanced maternal age at child birth is of prospective relevance for adult IMT levels in a healthy German population and this association may be of adverse relevance for females only., Competing Interests: The authors have declared that no competing interests exist.

Objective: To compare progression of subclinical atherosclerosis and factors promoting it in patients with SLE and controls., Methods: Consecutive patients with SLE and age-matched, sex-matched population controls from the SLEVIC cohort were assessed at inclusion and after 7 years with standardised data collection and carotid ultrasound. Effect of risk factors on carotid intima-media thickness (cIMT) progression was examined with adjusted linear mixed models., Results: A total of 77 patients and 74 controls, 68% and 61% of the original cohort, completed follow-up. The patients were (mean) 47 years old, 90% were women, and controls were 51 years old, 92% women. Patients had disease duration of (mean) 11 years, mild disease activity and low severity at both assessments. Baseline cIMT did not differ between the groups. An average absolute cIMT progression was 0.009 mm/year in patients and 0.011 mm/year in controls, intergroup difference p=0.9.Of factors at inclusion, dyslipidaemia, lower levels of high-density lipoprotein (HDL) and carotid plaque in patients and controls, and higher systolic blood pressure, total cholesterol:HDL and LDL:HDL ratios and triglycerides in patients were associated with cIMT progression. Of factors at follow-up, hypertension and blood lipids in patients and HDL in controls were significantly associated with cIMT progression. History of lupus nephritis and a higher average dose of prednisolone used since diagnosis were associated with cIMT progression in patients. Associations of risk factors with cIMT progression were stronger in presence of plaques., Conclusion: We observed a statistically comparable progression of cIMT in patients with mild SLE and controls over 7 years, which implies that progression of subclinical atherosclerosis in some patients with SLE could follow that of the general population. Traditional cardiovascular (CV) risk factors, history of lupus nephritis and higher use of corticosteroids promote cIMT progression in SLE. Detection of carotid plaque may add to CV risk stratification., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2020. Re-use permitted under CC BY-NC.

Background: The relationship between alcohol consumption and atherosclerosis has not been sufficiently examined among people living with HIV (PLWH)., Methods: We analyzed data from PLWH in the Women's Interagency HIV Study (WIHS; n = 1,164) and the Multicenter AIDS Cohort Study (MACS; n = 387) with no history of cardiovascular disease (CVD). Repeated measures of intima-media thickness of the right common carotid artery (CCA-IMT) were assessed using B-mode ultrasound from 2004 to 2013. Current alcohol consumption was collected at time of CCA-IMT measurement and was categorized according to gender-specific weekly limits. Group-based trajectory models categorized participants into past 10-year consumption patterns (1994 to 2004). Multivariate generalized estimating equations were conducted to assess the association of past and current alcohol use patterns on change in CCA-IMT by cohort, controlling for age, race, cigarette and illicit drug use, probable depression, HIV RNA viral load, antiretroviral therapy exposure, and hepatitis C coinfection., Results: Among the WIHS, past heavy alcohol consumption was associated with increased CCA-IMT level over time (β = 8.08, CI 0.35, 15.8, p = 0.04), compared to abstinence. Among the MACS, compared to abstinence, all past consumption patterns were associated with increased CCA-IMT over time (past low: β = 15.3, 95% CI 6.46, 24.2, p < 0.001; past moderate: β = 14.3, CI 1.36, 27.2, p = 0.03; past heavy: β = 21.8, CI 4.63, 38.9, p = 0.01). Current heavy consumption was associated with decreased CCA-IMT among the WIHS (β = -11.4, 95% CI -20.2, -2.63, p = 0.01) and MACS (β = -15.4, 95% CI -30.7, -0.13, p = 0.04). No statistically significant time by consumption pattern effects were found., Conclusions: In both cohorts, 10-year heavy consumption was associated with statistically significant increases in carotid artery thickness, compared to abstinence. Long-term patterns of drinking at any level above abstinence were particularly significant for increases in IMT among men, with heavy consumption presenting with the greatest increase. Our results suggest a potentially different window of risk among past and current heavy drinkers. Further studies are needed to determine whether alcohol consumption level is associated with intermediate measures of atherosclerosis. Alcohol screening and interventions to reduce heavy consumption may benefit PLWH who are at risk of CVD., (© 2019 by the Research Society on Alcoholism.)

Introduction: Carotid Intima Media Thickness (CIMT) is a marker of subclinical atherosclerosis, associated with cardiovascular risk in adults. Telomere length (TL) is a marker of cellular ageing. We sought to determine whether telomere length in early childhood and/or at 14-years is associated with CIMT in adolescence, in a community-based cohort study., Methods: 118 children had TL measured at mean age 3.6-years and 165 children had TL and CIMT, measured at 14-years, from the community-based Childhood Asthma Prevention Study., Results: TL in early childhood was significantly inversely associated with CIMT at 14 years, p = 0.04. TL in teenage life was also significantly inversely associated with CIMT at 14 years, p = 0.03. This latter association was no longer significant, however, after adjusting for early life TL., Conclusion: TL measured in early childhood and adolescence is significantly associated with CIMT at 14-years, suggesting that telomere length is a biological marker or even early determinant of late cardiovascular risk., (Copyright © 2018 Elsevier B.V.

Background/objectives: Evidence of an association between sleep disorders and extracranial atherosclerosis is limited and has not been studied in remote rural settings, where living conditions and cardiovascular risk factors are different than in urban centers. We assessed the relationship between the carotid intima-media thickness (cIMT) and sleep quality in stroke-free individuals aged ≥40 years living in rural Ecuador., Methods: Applying a population-based study design, participants underwent face-to-face interviews using the Pittsburgh Sleep Quality Index (PSQI) to assess sleep quality, and sonographic examinations for measurement of the carotid intima-media thickness (cIMT). The association between the cIMT and sleep quality (as the dependent variable) was assessed by means of generalized linear models, adjusted for relevant confounders., Results: The mean age of 561 participants was 60.4 ± 12.6 years (58% women). The mean PSQI was 4.6 ± 2.2 points. Of those, 79 (14%) individuals had an increased cIMT (>1 mm). A model adjusted for demographics showed a significant association between increased cIMT and the PSQI score (β: 0.602; 95% C.I.: 0.027-1.177; p = 0.040). This relationship was reduced when cardiovascular risk factors were added to the model (β: 0.514; 95% C.I.: -0.072 - 1.101; p = 0.086). When the model was adjusted for demographics and psychological distress, the association between increased cIMT and the PSQI score became significant (β: 0.573; 95% C.I.: 0.013-1.133; p = 0.045). In addition, both symptoms of depression (p = 0.032) and anxiety (p < 0.001) remained independently significant., Conclusions: This study shows an association between increased cIMT and the PSQI score, which is, at least, partly mediated by manifestations of psychological distress., (Copyright © 2018 Elsevier B.V.

Objectives: The endothelial dysfunction-arterial stiffness-atherosclerosis continuum plays an important pathophysiological role in hypertension. The aim of this study was to investigate the cross-sectional association between serum uric acid (SUA) and vascular markers related to this continuum, and to assess the longitudinal association between SUA and endothelial function that represents the initial step of the continuum., Methods: We evaluated the baseline associations between SUA levels and vascular markers that included flow-mediated vasodilatation (FMD), brachial-ankle pulse wave velocity (baPWV), and common carotid artery intima-media thickness (CCA-IMT) in 648 subjects receiving antihypertensive treatment. The longitudinal association between baseline SUA levels and FMD measured at 1.5 and 3 yr of follow-up was also investigated., Results: At baseline, modest, but significant correlations were observed between SUA and FMD in females (r = -0.171), baPWV in males with SUA >368.78 μmol/L (r = -0.122) and in females with a SUA level ≤ 362.83 μmol/L (r = 0.217), mean CCA-IMT in females with a SUA level ≤ 333.09 μmol/L (r = 0.139), and max CCA-IMT in females with SUA level ≤ 333.09 μmol/L (r = 0.138). A longitudinal association between SUA and FMD was less observed in males. In females, the baseline SUA was associated significantly with FMD values at 1.5 yr (r = -0.211), and SUA levels >237.92 μmol/L were associated significantly and independently with FMD values at 3 yr (r = -0.166)., Conclusions: Lower SUA levels were associated with better vascular markers of the continuum, especially in females. Furthermore, we observed a longitudinal association between SUA and endothelial function, suggesting SUA level may be a potential marker of the continuum in hypertension., (Copyright © 2018 Elsevier B.V.

Background: Previous clinical studies found inconsistent relationship between circulating sclerostin levels and treatment outcome in patients undergoing maintenance hemodialysis (MHD). Therefore, this study aimed to assess the associations of sclerostin with carotid artery atherosclerosis and all-cause mortality in Chinese patients undergoing MHD., Methods: This retrospective study assessed 84 patients undergoing MHD at the Nephrology Department of Beijing Hospital from January to April 2012, with a median follow-up of 61.2 months (range: 11.5 to 63 months). Carotid artery intima-media thicknesses (CIMTs) and atherosclerotic plaques were measured by B-mode Doppler ultrasound at baseline. Blood samples were collected for measuring serum sclerostin and soluble klotho (s-klotho) levels. The associations of sclerostin levels with carotid artery atherosclerosis was evaluated by correlation methods. Predictive factors of mortality were assessed by multivariate COX regression., Results: Baseline serum sclerostin averaged 162.01 pmol/L, with an interquartile range of 121.69 to 225.22 pmol/L, while CIMT values were 1.35 ± 0.39 mm. Carotid artery atherosclerotic plaques were detected in 68 subjects (81%). Subjects with sclerostin levels above the median value had higher CIMT (p = 0.038) and higher prevalence of atherosclerotic plaque (p = 0.025). During follow-up, 27 patients died; Kaplan-Meier curves indicated that subjects with high sclerostin levels (above the median value at baseline) had shorter survival (log rank p = 0.011). In multivariate COX regression analysis, serum sclerostin (HR, 1.095; 95% confidence interval [CI] 1.022-1.174, p = 0.010) and albumin (HR, 0.742; 95%CI 0.612-0.900, p = 0.002) levels were independent predictors of all-cause mortality., Conclusions: Sclerostin is positively associated with CIMT. In addition, patients with low baseline serum sclerostin undergoing MHD show better survival.

Background: Carotid plaque has emerged as a marker of coronary heart disease (CHD) risk. Comparison of carotid plaque burden between different race/ethnic groups may provide a relative estimate of their future CHD risk., Methods: We conducted a population-based study among apparently healthy middle-aged men aged 40-49 years (ERA JUMP study (n = 924)) and recruited 310 Whites in Pittsburgh, US, 313 Japanese in Otsu, Japan, and 301 Koreans in Ansan, South Korea. The number of carotid plaque and CHD risk factors was assessed using a standardized protocol across all centers. The burden of carotid plaque was compared between race/ethnic groups after adjustment for age and BMI, and after multivariable adjustment for other CHD risk factors using marginalized zero-inflated Poisson regression models. Cross-sectional associations of risk factors with plaque were examined., Results: Whites (22.8%) had more than four-fold higher prevalence (p < 0.01) of carotid plaque than Japanese men (4.8%) while the prevalence among Koreans was 10.6%. These differences remained significant after adjustment for age, BMI as well as other risk factors - incidence density ratio (95% confidence interval) for plaque was 0.13 (0.07, 0.24) for Japanese and 0.32 (0.18, 0.58) for Koreans as compared to Whites. Age, hypertension and diabetes were the only risk factors significantly associated with presence of carotid plaque in the overall population., Conclusion: Whites have significantly higher carotid plaque burden than men in Japan and Korea. Lower carotid plaque burden among Japanese and Koreans is independent of traditional CVD risk factors., (Copyright © 2018 Elsevier B.V. All rights reserved.)

Background: Data concerning the relationship between cardiovascular risk factors, plasmatic markers, carotid disease and extent of coronary lesions are lacking., Objectives: To evaluate the role of cardiovascular risk factors, plasmatic levels of high sensitivity C-reactive protein (hs-CRP), fibrinogen, lipoprotein(a), and carotid plaque extension in predicting the severity of coronary artery disease (CAD)., Methods: We analyzed 574 subjects undergoing first coronary angiography. For angiographic analysis, we used the Syntax Score and we defined the prognostic localization of CAD as a critical stenosis of the left main and/or proximal segment of left anterior descending artery. Levels of hs-CRP >3mg/L, lipoprotein(a) plasma levels >30mg/dL and plasma fibrinogen >300mg/dL were considered critical. Significant carotid disease (SCD) was defined by the presence of lesions producing a 50% diameter stenosis with a peak systolic velocity >125cm/s. A mean carotid intima media thickness (IMT) >0.9mm was considered abnormal., Results: In the adjusted analysis the presence of SCD was found to be an independent predictor of high Syntax Score (p<0.001), while high fibrinogen levels were independently associated with the presence of CAD in prognostic localization (p=0.04). In the sub-group of patients without SCD, IMT >0.9mm was found to be an independent predictor of the presence of CAD (p<0.001)., Conclusions: SCD strongly predicts high Syntax Score, while IMT shows excellent positive predictive value for the presence of CAD. In addition, high plasma fibrinogen levels are associated with coronary stenoses in prognostic localization., (Copyright © 2017 Elsevier B.V. All rights reserved.)

Circulating lipopolysaccharide-binding protein (LBP), a metabolic endotoxemia marker, was identified as an independent predictor of atherosclerosis. Although increases in carotid intima-media thickness (CIMT) were repeatedly reported in obstructive sleep apnea (OSA), neither the role of OSA in metabolic endotoxemia nor of LBP in early atherosclerosis were explored in patients with OSA. At a tertiary university hospital we investigated the relationships between OSA, LBP and CIMT in 117 men who underwent full polysomnography and CIMT assessment by B-mode ultrasound. Circulating LBP concentrations and average CIMT increased from patients without OSA to those with mild-moderate and severe OSA (from 32.1+/-10.3 to 32.3+/-10.9 to 38.1+/-10.3 microg.ml(-1), p=0.015; from 0.52+/-0.09 to 0.58+/-0.06 to 0.62+/-0.10 mm, p=0.004, respectively). Oxygen desaturation index (ODI) was a predictor of serum LBP levels independent of age, waist-to-hip ratio (WHR), smoking, hypertension, HDL cholesterol, triglycerides and fasting glucose [p (ANOVA)=0.002, r(2)=0.154], with no independent effect of the ODI*WHR interaction term on LBP. Furthermore, serum LBP predicted CIMT independently of known risk factors of atherosclerosis including obesity (p<0.001, r(2)=0.321). Our results suggest that OSA severity contributes to metabolic endotoxemia in patients with OSA independently of obesity, and that LBP might represent a contributing factor promoting early atherosclerosis in such patients.

Objectives: To examine the longitudinal mutual association between endothelial dysfunction and arterial stiffness, and also to determine which of the two variables was more closely associated with the progression of subclinical organ damage., Methods: The brachial-ankle pulse wave velocity (baPWV), carotid intima-media thickness (CIMT), estimated glomerular filtration rate, microalbuminuria and flow-mediated vasodilatation of the brachial artery (FMD) were measured three times at 1.5-year intervals in 674 Japanese patients receiving antihypertensive treatment., Results: The change of the baPWV during the study period was larger in the subjects with baseline FMD values in the lowest tertile as compared to those with baseline FMD values in the highest tertile. The change of the CIMT was smaller in the subjects with baseline baPWV values in the lowest tertile than in those with baseline baPWV values in the highest tertile. After the adjustment, the FMD value at the baseline was inversely associated with the baPWV at the end of the study period (beta=-0.07, p=0.01), although, the reverse association was not significant. The baPWV, but not the FMD value, at the baseline was associated with the CIMT (beta=0.06, p=0.04) measured at the end of the study period., Conclusions: In hypertension, endothelial dysfunction was associated with the progression of arterial stiffness, although the reverse association was not confirmed. The increased arterial stiffness rather than endothelial dysfunction may be more closely associated with the progression of atherosclerotic vascular damage, and the endothelial dysfunction-arterial stiffness-atherosclerosis continuum may be important in hypertension., (Copyright © 2017 Elsevier Ireland Ltd.

Background: A great debate in literature exists nowadays on the role of uric acid as a marker of cardiovascular and metabolic organ damage or a risk factor for cardiovascular and metabolic disease., Methods: The study aimed to determine the relationship among serum uric acid and metabolic syndrome and atherosclerosis, by means of carotid intima media-thickness, in a cohort of 811 otherwise healthy overweight/obese subjects, without overt atherosclerosis not using any kind of drug., Results: Uric acid levels were positively related to male gender, waist circumference, BMI, systolic and diastolic pressure levels, fasting insulin, fasting glucose, HOMA-IR, triglycerides, total cholesterol, LDL cholesterol, the presence of metabolic syndrome and the number of the components of metabolic syndrome and negatively related to HDL cholesterol levels. No correlation was found between uric acid and carotid intima media thickness. At the multiple regression analysis, only waist circumference and triglycerides (positively) and HDL-cholesterol (negatively) maintained an independent association with uric acid as dependent variable, while age, female gender and uric acid showed a significant independent association with metabolic syndrome as dependent variable. Moreover, the analysis of the odd ratios showed that the risk of developing metabolic syndrome was consistent with uric acid levels ranging from 3 mg/dl to 8 mg/dl., Conclusion: The presence of metabolic syndrome does not seem to provide hyperuricemia. By contrast, higher serum uric acid level may predict the risk of metabolic syndrome. Moreover, our results suggest that uric acid cannot be considered a risk factor for early atherosclerosis, at least when assessed using carotid ultrasound., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.org.)

Background: Growth hormone treatment reduces blood pressure and lipid concentrations. We assessed long-term changes in blood pressure, lipid concentrations, and carotid intima media thickness over a 5-year period after cessation of growth hormone treatment in adults born small for gestational age., Methods: We did a longitudinal observational study at a medical centre in the Netherlands between April 1, 2004, and April 1, 2016. We included adults born small for gestational age who were treated with growth hormone (1 mg/m 2 per day); treatment started during childhood until adult height. Participants were evaluated at cessation of treatment, and 6 months, 2 years, and 5 years later. We compared cardiovascular risk factors with untreated controls from the PROGRAM study., Findings: We included 199 participants born small for gestational age and treated with growth hormone along with 285 controls: 51 untreated short adults born small for gestational age, 92 untreated adults born small for gestational age with spontaneous catch-up growth, and 142 adults born appropriate for gestational age. In the 6 months after treatment cessation, systolic blood pressure increased temporarily from 113·00 mm Hg (95% CI 111·18-114·82) to 116·92 mm Hg (115·07 to 118·77; p<0·001) and diastolic blood pressure increased temporarily from 62·19 mm Hg (60·99-63·38) to 66·51 mm Hg (65·14-67·89; p<0·001). At 5 years after treatment cessation, mean systolic blood pressure was 109·2 mm Hg (105·5-113·0) and mean diastolic blood pressure was 63·4 mm Hg (60·9-65·9), similar to the values at cessation. Lipid concentrations were non-significantly higher 5 years after treatment cessation (p values 0·09-0·21) than at treatment cessation. Cessation of growth hormone had no effect on carotid intima media thickness. At 5 years after cessation, total cholesterol was lower in adults treated with growth hormone (mean 4·21 mmol/L, 95% CI 4·04-4·38) than in untreated short adults born small for gestational age (4·66 mmol/L, 4·42-4·92; p=0·0030), as was mean LDL cholesterol (2·28 mmol/L, 2·14-2·43 vs 2·85 mmol/L, 2·62-3·10; p<0·0001); blood pressure and carotid intima media thickness did not differ between these two groups (p values >0·12). At 5 years after cessation, systolic blood pressure, diastolic blood pressure, lipid concentrations, and carotid intima media thickness of adults treated with growth hormone were not different to those in adults born small for gestational age who had spontaneous catch-up growth or adults born appropriate for gestational age., Interpretation: Long-term growth hormone treatment in children born small for gestational age has no unfavourable effects on cardiovascular health in early adulthood and improves lipid profiles., Funding: Novo Nordisk (Netherlands)., (Copyright © 2017 Elsevier Ltd.

Work stress can increase the risk of cardiovascular disease by 50%, with increasing research focusing on the underlying mechanisms responsible for these associations. Our meta-analysis assessed the associations of the effort-reward imbalance (ERI) workplace stress model with indices of cardiovascular disease. The search term 'effort*reward*imbalance' produced 22 papers (129 associations, N=93,817) meeting inclusion criteria. Greater ERI was most associated with increased hypertension (r=0.26, p<0.001, N=1180), intima media thickness (r=0.23, p<.001, N=828) and fibrinogen (r=0.13, p=0.03, N=4315). Trait over-commitment was most associated with increased hypertension (r=0.24, p=0.02, N=899) and intima media thickness (r=0.19, p=0.02, N=828). Interventions aimed at reducing the impact of ERI and over-commitment on cardiovascular disease should consider concurrently assessing changes in physiological markers of cardiovascular disease., (Copyright © 2017 Elsevier Ltd.

Background/aim: To evaluate and stratify early cardiovascular risk of transsexuals who underwent pharmacological and/or surgical gender reassignment., Methods: Fifty-six transsexuals were divided into two groups: group 1 - underwent gonadectomy (orchiectomy for transwomen and hystero-annessiectomy for transmen); group 2 - hormone replacement therapy alone. All participants underwent carotid artery intima-media thickness (C-IMT) and flow-mediated vasodilation (FMD) of brachial artery evaluations., Results: FMD was lower in patients who had undergone gonadectomy compared with non-surgically treated patients (Group 1: 5.711 vs Group 2: 7.339, P < 0.0001). Mean C-IMT was higher in group 1 than group 2 (group 1: 0.733 vs group 2: 0.582). The duration of hormone therapy correlates positively with mean C-IMT (B = 0.001) and negatively with FMD (%) (B = - 0.007)., Conclusions: Cardiovascular risk, which is expressed in terms of endothelial (FMD) and morphological (C-IMT) dysfunction, increases in subjects undergoing gonadectomy compared with those receiving cross-sex reassignment therapy alone., (© 2017 Royal Australasian College of Physicians.)

Background: Inter-arm systolic blood pressure difference (SBPD) is an easily obtained patient characteristic which relates to vascular disease. We aimed to identify determinants of large inter-arm SBPD and to investigate the relation between inter-arm SBPD and vascular events in patients with and without manifest vascular disease., Methods: In a cohort of 7344 patients with manifest vascular disease or vascular risk factors alone enrolled in the Second Manifestations of ARTerial disease (SMART) study, single bilateral non-simultaneous blood pressure measurements were performed. Logistic and Cox regression was used to identify determinants of large inter-arm SBPD (≥15mmHg) and to investigate the relation between inter-arm SBPD and vascular events (composite of non-fatal myocardial infarction, stroke, and vascular mortality) and all-cause mortality., Results: In all patients the median inter-arm SBPD was 7mmHg (IQR 3-11) and 1182 (16%) patients had inter-arm SBPD ≥15mmHg. Higher age, higher systolic blood pressure, diabetes mellitus, peripheral artery disease, carotid artery stenosis, higher carotid intima-media thickness, and lower ankle-brachial indices were related to large inter-arm SBPD (≥15mmHg). Each 5mmHg increase in inter-arm SBPD was related to a 12% higher risk of vascular events in patients without manifest vascular disease (HR 1.12; 95% CI 1.00-1.27), whereas no relation was apparent in patients with manifest vascular disease (HR 0.98; 95% CI 0.93-1.04, interaction p-value 0.036). Inter-arm SBPD was not related to all-cause mortality (HR 1.05; 95% CI 0.93-1.19)., Conclusions: Inter-arm SBPD relates to a higher risk of vascular events in patients without manifest vascular disease, whereas this relation is not apparent in patients with manifest vascular disease., (Copyright © 2017 Elsevier B.V.

Objective: Mechanisms and interactions among intravascular cells contributing to development of subclinical atherosclerosis are poorly understood. In women, both menopausal status and pregnancy history influence progression of atherosclerosis. This study examined activation and interactions among blood elements with subclinical atherosclerosis in menopausal women with known pregnancy histories., Methods: Carotid intima-media thickness (CIMT), as a marker of subclinical atherosclerosis, was measured using B-mode ultrasound in age- and parity-matched women [40 with and 40 without a history of preeclampsia] 35 years after the index pregnancy. Interactions among intravascular cells (38 parameters) were measured by flow cytometry in venous blood. Data analysis was by principal component which retained 7 independent dimensions accounting for 63% of the variability among 38 parameters., Results: CIMT was significantly greater in women with a history of preeclampsia (P = 0.004). Platelet aggregation and platelet interactions with granulocytes and monocytes positively associated with CIMT in postmenopausal women independent of their pregnancy history (ρ = 0.258, P< 0.05). However, the association of the number of platelets, platelet activation and monocyte-platelet interactions with CIMT differed significantly depending upon pregnancy history (test for interaction, P<0.001)., Conclusion: Interactions among actived intravascular cells and their association with subclinical atherosclerosis differ in women depending upon their pregnancy histories.

Background: Dickkopf-related protein 3 (DKK3) is a secreted protein that is involved in the regulation of cardiac remodeling and vascular smooth muscle cell differentiation, but little is known about its role in atherosclerosis., Methods: We tested the hypothesis that DKK3 is atheroprotective using both epidemiological and experimental approaches. Blood DKK3 levels were measured in the Bruneck Study in 2000 (n=684) and then in 2005 (n=574). DKK3 -deficient mice were crossed with apolipoprotein E -/- mice to evaluate atherosclerosis development and vessel injury-induced neointimal formation. Endothelial cell migration and the underlying mechanisms were studied using in vitro cell culture models., Results: In the prospective population-based Bruneck Study, the level of plasma DKK3 was inversely related to carotid artery intima-media thickness and 5-year progression of carotid atherosclerosis independently from standard risk factors for atherosclerosis. Experimentally, we analyzed the area of atherosclerotic lesions, femoral artery injury-induced reendothelialization, and neointima formation in both DKK3 -/- /apolipoprotein E -/- and DKK3 +/+ /apolipoprotein E -/- mice. It was demonstrated that DKK3 deficiency accelerated atherosclerosis and delayed reendothelialization with consequently exacerbated neointima formation. To explore the underlying mechanisms, we performed transwell and scratch migration assays using cultured human endothelial cells, which exhibited a significant induction in cell migration in response to DKK3 stimulation. This DKK3-induced migration activated ROR2 and DVL1, activated Rac1 GTPases, and upregulated JNK and c-jun phosphorylation in endothelial cells. Knockdown of the ROR2 receptor using specific siRNA or transfection of a dominant-negative form of Rac1 in endothelial cells markedly inhibited cell migration and downstream JNK and c-jun phosphorylation., Conclusions: This study provides the evidence for a role of DKK3 in the protection against atherosclerosis involving endothelial migration and repair, with great therapeutic potential implications against atherosclerosis., (© 2017 The Authors.)

Background: Heterozygous familial hypercholesterolemia (HeFH) is an autosomal dominant disorder leading to premature atherosclerosis. Children with HeFH exhibit early signs of atherosclerosis manifested by increased carotid intima-media thickness (IMT). In this study, we assessed the effect of 2-year treatment with rosuvastatin on carotid IMT in children with HeFH., Methods: Children with HeFH (age, 6-<18 years) and low-density lipoprotein cholesterol >4.9 mmol/L or >4.1 mmol/L in combination with other risk factors received rosuvastatin for 2 years, starting at 5 mg once daily, with uptitration to 10 mg (age, 6-<10 years) or 20 mg (age, 10-<18 years). Carotid IMT was assessed by ultrasonography at baseline and 12 and 24 months in all patients and in age-matched unaffected siblings. Carotid IMT was measured at 3 locations (common carotid artery, carotid bulb, internal carotid artery) in both the left and right carotid arteries. A linear mixed-effects model was used to evaluate differences in carotid IMT between children with HeFH and the unaffected siblings. P values were adjusted for age, sex, carotid artery site, and family relations., Results: At baseline, mean±SD carotid IMT was significantly greater for the 197 children with HeFH compared with the 65 unaffected siblings (0.397±0.049 and 0.377±0.045 mm, respectively; P =0.001). During 2 years of follow-up, the change in carotid IMT was 0.0054 mm/y (95% confidence interval, 0.0030-0.0082) in children with HeFH and 0.0143 mm/y (95% confidence interval, 0.0095-0.0192) in unaffected siblings ( P =0.002). The end-of-study difference in mean carotid IMT between children with HeFH and unaffected siblings after 2 years was no longer significant (0.408±0.043 and 0.402±0.042 mm, respectively; P =0.2)., Conclusions: In children with HeFH who were ≥6 years of age, carotid IMT was significantly greater at baseline compared with unaffected siblings. Rosuvastatin treatment for 2 years resulted in significantly less progression of increased carotid IMT in children with HeFH than untreated unaffected siblings. As a result, no difference in carotid IMT could be detected between the 2 groups after 2 years of rosuvastatin. These findings support the value of early initiation of statin treatment for low-density lipoprotein cholesterol reduction in children with HeFH., Clinical Trial Registration: URL: http://www.clinicaltrials.gov.

Background and Purpose: Ultrasound markers of carotid atherosclerosis may be related to cognitive status. We hypothesized that individuals with greater carotid intima-media thickness (cIMT) and carotid plaque burden would exhibit worse cognition., Methods: One thousand one hundred sixty-six stroke-free participants from the NOMAS (Northern Manhattan Study) underwent carotid ultrasound and neuropsychological examination. Among them, 826 underwent a second neuropsychological examination an average of 5 years later. cIMT and plaque were assessed by a standardized B-mode ultrasound imaging and reading protocol. We used multivariable linear regression to examine cIMT, carotid plaque presence, and carotid plaque area as correlates of domain-specific neuropsychological Z scores cross-sectionally and over time. We also investigated possible effect modification by APOE ε4 allele, age, and race/ethnicity., Results: Participants had a mean (SD) age of 70 (9) years and were 60% women, 66% Hispanic, 15% white, and 18% black. Those with greater cIMT exhibited worse episodic memory after adjustment for demographics and vascular risk factors (β=-0.60; P =0.04). APOE ε4 carriers with greater cIMT exhibited worse episodic memory (β=-1.31; P =0.04), semantic memory (β=-1.45; P =0.01), and processing speed (β=-1.21; P =0.03). Participants with greater cIMT at baseline did not exhibit significantly greater cognitive decline after adjustment. APOE ε4 noncarriers with greater cIMT exhibited greater declines in executive function (β=-0.98; P =0.06). Carotid plaque burden was not significantly associated with cognition at baseline or over time., Conclusions: Subclinical carotid atherosclerosis was associated with worse cognition among those at higher risk for Alzheimer disease. Interventions targeting early stages of atherosclerosis may modify cognitive aging., (© 2017 The Authors.)

Background and Purpose: A short-term increase in dietary nitrate (NO 3 - ) improves markers of vascular health via formation of nitric oxide and other bioactive nitrogen oxides. Whether this translates into long-term vascular disease risk reduction has yet to be examined. We investigated the association of vegetable-derived nitrate intake with common carotid artery intima-media thickness (CCA-IMT), plaque severity, and ischemic cerebrovascular disease events in elderly women (n=1226)., Methods: Vegetable nitrate intake, lifestyle factors, and cardiovascular disease risk factors were determined at baseline (1998). CCA-IMT and plaque severity were measured using B-mode carotid ultrasound (2001). Complete ischemic cerebrovascular disease hospitalizations or deaths (events) over 14.5 years (15 032 person-years of follow-up) were obtained from the West Australian Data Linkage System., Results: Higher vegetable nitrate intake was associated with a lower maximum CCA-IMT (B=-0.015, P =0.002) and lower mean CCA-IMT (B=-0.012, P =0.006). This relationship remained significant after adjustment for lifestyle and cardiovascular risk factors ( P ≤0.01). Vegetable nitrate intake was not a predictor of plaque severity. In total 186 (15%) women experienced an ischemic cerebrovascular disease event. For every 1 SD (29 mg/d) higher intake of vegetable nitrate, there was an associated 17% lower risk of 14.5-year ischemic cerebrovascular disease events in both unadjusted and fully adjusted models ( P =0.02)., Conclusions: Independent of other risk factors, higher vegetable nitrate was associated with a lower CCA-IMT and a lower risk of an ischemic cerebrovascular disease event., (© 2017 American Heart Association, Inc.)

Background: Patients with cluster headache tend to have a dysregulation of systemic blood pressure such as increased blood pressure variability and decreased nocturnal dipping. This pattern of nocturnal nondipping is associated with end-organ damage and increased risk of cardiovascular disease., Objective: To determine if cluster headache is associated with a higher risk of cardiovascular disease., Methods: Cross-sectional study of 33 cluster headache patients without evidence of cardiovascular disease and 30 age- and gender-matched healthy controls. Ambulatory blood pressure monitoring was performed in all subjects. We evaluate anthropometric, hematologic, and structural parameters (carotid intima-media thickness and ankle-brachial index)., Results: Of the 33 cluster headache patients, 16 (48.5%) were nondippers, a higher percentage than expected. Most of the cluster headache patients (69.7%) also presented a pathological ankle-brachial index. In terms of the carotid intima-media thickness values, 58.3% of the patients were in the 75th percentile, 25% were in the 90th percentile, and 20% were in the 95th percentile. In the control group, only five of the 30 subjects (16.7%) had a nondipper pattern ( P  =   0.004), with 4.54% in the 90th and 95th percentiles ( P  =   0.012 and 0.015)., Conclusions: Compared with healthy controls, patients with cluster headache presented a high incidence (48.5%) of nondipper pattern, pathological ankle-brachial index (69.7%), and intima-media thickness values above the 75th percentile. These findings support the hypothesis that patients with cluster headache present increased risk of cardiovascular disease., (© 2016 American Academy of Pain Medicine. All rights reserved.

Background and Purpose: Atherogenic changes in lipids occur among women around the time of the natural menopause, that is, within 1 year of the final menstrual period (FMP). We investigated whether lipid changes around the FMP are related to carotid intima-media thickness, interadventitial diameter, and plaque in postmenopausal women., Methods: A total of 863 natural postmenopausal women with no history of heart attack or stroke underwent carotid ultrasound scans at follow-up year 12 or 13 of the Study of Women's Health Across the Nation. Estimates of their annual change in lipids were segmented into the year before and after the FMP, before the year before FMP, and 1 year after FMP. Multivariate analyses were adjusted for sociodemographic characteristics, time from FMP to scan, baseline body mass index and systolic blood pressure, and use of medications for hypertension and diabetes mellitus at the scan., Results: Smaller increases in high-density lipoprotein cholesterol and apolipoprotein A1 within 1 year of the FMP were related to greater interadventitial diameter, β (SE)=-0.036 (0.015), P=0.02, and β (SE)=-0.035 (0.013), P=0.006, respectively. Greater increases in low-density lipoprotein cholesterol within 1 year of FMP were related to greater likelihood of plaque scores ≥2, odds ratio, 1.071; 95% confidence interval, 1.018-1.127; P=0.009. Magnitude of associations was reduced but remained significant with further adjustment for premenopausal lipid levels. The difference in probability of elevated plaque scores was 50% between those in the highest and lowest low-density lipoprotein cholesterol change tertiles., Conclusions: Changes in lipids as women approach the FMP provide useful clinical information for understanding postmenopausal carotid indices., (© 2016 American Heart Association, Inc.)

Background: Pentraxin-3 (PTX3) is a long pentraxin that is supposed to participate in the inflammatory process and in atherosclerosis., Aim: To study PTX3 serum levels in rheumatoid arthritis (RA) patients to know if its serum levels may reflect disease activity and/or subclinical atherosclerosis., Methods: PTX3 and carotid intima media thickness (IMT) were studied in 85 RA patients (83.5% females, median age of 59years old, median disease duration of 13years) along with its demographic, clinical, serological and lipid profile. For comparison PTX3 was measured in 85 healthy volunteers., Results: PTX3 levels in RA patients were similar to controls (p=0.21) and did not correlate with inflammatory activity measured by ESR (p=0.39) CRP (p=0.18) and DAS28 (p=0.67). Serum PTX3 levels were higher in nonobese RA patients than in obese (BMI vs PTX3 with rho=-0.27; 95%IC=-0.46 to -0.06; p=0.009). In non-obese patients, PTX3 correlated negatively with carotid IMT (rho=-0.40; 95%IC=-0.66 to -0.06; p=0.01) but not in the obese ones (p=0.26). In the obese RA patients there was a negative correlation between PTX3 levels and LDL/HDL ratio (Rho=-0.29; 95%IC=-0.53-0.01; p=0.03)., Conclusions: PTX3 levels do not reflect inflammatory process in RA. However, it exerts a protective role in the process of atherogenesis in non-obese RA patients., (Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.)

Background and Purpose: Emerging work has linked menopausal vasomotor symptoms (VMS) to subclinical cardiovascular disease (CVD) among women. However, VMS are dynamic over time. No studies have considered how temporal patterns of VMS may relate to subclinical CVD. We tested how temporal patterns of VMS assessed over 13 years were related to carotid intima media thickness (IMT) among midlife women., Methods: The Study of Women's Health Across the Nation is a longitudinal cohort study of midlife women. Eight hundred and eleven white, black, Hispanic, and Chinese participants with a well-characterized final menstrual period completed measures of VMS, a blood draw, and physical measures approximately annually for 13 years. Women underwent a carotid artery ultrasound at study visit 12., Results: Four trajectories of VMS were identified by trajectory analysis (consistently high, early-onset, late-onset, persistently low VMS) and tested in relation to carotid indices in linear regression models. Results indicated that women with early-onset VMS had both greater mean IMT (beta, b [standard error, SE]=0.03 [0.01], P=0.03) and greater maximal IMT (b [SE]=0.04 [0.01], P=0.008) than women with consistently low VMS, adjusting for demographics and CVD risk factors., Conclusions: This is the first study to test trajectories of VMS in relation to subclinical CVD. Women with VMS early in the menopause transition had higher mean IMT and maximal IMT than those with consistently low VMS across the transition. Associations were not accounted for by demographic factors nor by CVD risk factors. Results can signal to women in need of early CVD risk reduction., (© 2015 American Heart Association, Inc.)

Endothelial function has diagnostic, prognostic and therapeutic significance. A number of non-invasive techniques were introduced for its assessment, including flow-mediated dilation (FMD), finger plethysmography (RH-PAT) and digital thermal monitoring (DTM). All these methods can be performed simultaneously. In addition, various methods for measuring arterial wall stiffness are available such as: pulse wave analysis (PWA), pulse wave velocity (PWV), pulse contour analysis (PCA) and carotid wall distensibility coefficient (DC). Finally, carotid intima-media thickness (cIMT) and ankle brachial index (ABI) are used as surrogate read-outs of atherosclerosis. Here, we briefly describe the advantages, limitations and interrelationships of various methods used for the assessment of endothelial function, arterial stiffness, and present the concept of an integrated evaluation of vascular health based on multiple methods. This strategy may be useful to stratify cardiovascular risk and represents a step towards multiparametric assessment of endothelium for effective endothelium-guided therapy in patients with cardiovascular diseases., (Copyright © 2015.

Introduction: Juvenile idiopathic arthritis (JIA) is a frequent childhood rheumatic disease characterized by chronic inflammation. The latter has been related to impairment of arterial functional-structural properties, atherogenesis and later cardiovascular events. The objective of this study was to examine intima-media thickness (IMT) and the parameters of arterial stiffness in children with JIA at diagnosis and their correlation with JIA subtype and markers of inflammation and atherosclerosis., Methods: Thirty-nine newly diagnosed patients with JIA (26 girls; mean age, 13.2 ± 2.6 years) and 27 healthy controls (9 girls; mean age, 13.6 ± 3.4 years) were included in the study. Twelve patients had oligoarthritis, fifteen had extended oligoarthritis and twelve had rheumatoid factor-negative polyarthritis. IMT of the common carotid artery was determined by ultrasonography, carotid-femoral pulse wave velocity (cfPWV) and augmentation index adjusted to a heart rate of 75 beats/min (AIx@75) were determined by applanation tonometry. The serum levels of atherosclerosis-related biomarkers, such as asymmetric dimethylarginine (ADMA), myeloperoxidase (MPO) and adiponectin, were measured by enzyme-linked immunosorbent assay., Results: Mean IMT (0.46 ± 0.04 vs. 0.42 ± 0.04 mm; p = 0.0003) and MPO concentration (115.2 [95% confidence interval {95% CI}, 97.4-136.3] vs. 57.6 [95% CI, 47.1-70.3] ng/ml; p < 0.0001) were higher in the patients with JIA than in the control subjects. The cfPWV, AIx@75 and serum ADMA and adiponectin levels did not significantly differ between the groups and JIA subtypes. Serum adiponectin level correlated negatively with AIx@75 in patients with JIA (r = -0.38; p < 0.05)., Conclusions: Patients with JIA have increased mean IMT and elevated MPO levels at early stages of the disease. AIx@75 was inversely independently associated with adiponectin level in the patients, suggesting that lower adiponectin levels might influence arterial subclinical stiffening in patients with newly diagnosed JIA.

Background: We investigated the relationship between the glycemic indices glycated albumin (GA) and glycated hemoglobin (HbA1c) and the progression of diabetic vascular complications [diabetic nephropathy (DN) and carotid artery atherosclerosis (CAA)] in subjects with type 1 diabetes (T1D)., Methods: A total of 154 participants with a median follow-up of 2.8 years were enrolled in this retrospective longitudinal study. We recruited T1D subjects who had regularly measured urine albumin-creatinine ratios and estimated glomerular filtration rates, as well as tested HbA1c and GA levels consecutively every 3 or 6 months. A subgroup of 54 subjects was measured repeated carotid intima-media thickness (IMT)., Results: We classified subjects into the DN progression (Group I; n = 30) with either deteriorated stages of chronic kidney disease (n = 18) or albuminuria progression (n = 17), and the non-progression (Group II; n = 124). In multiple logistic regression analyses, baseline albuminuria (odds ratio [OR] = 2.64, 95 % confidence interval [CI] = 1.03-6.74), mean GA levels (OR = 2.03, 95 % CI = 1.27-3.26) were significantly associated with progression of DN. However, there was no association with mean HbA1c (OR = 0.98, 95 % CI = 0.62-1.54). In a subgroup analysis for follow-up measurements of carotid IMT, age was independently associated with the presence of plaque and the mean IMT. However glycemic indices were not significantly associated with CAA., Conclusions: Mean GA levels were more closely associated with DN progression than mean HbA1c in subjects with T1D. However, they were not associated with the CAA.

Background: Preeclampsia is a cardiovascular (CV) disease risk factor, and lifestyle modifications are recommended. It was suggested that preeclampsia may increase the prevalence of various CV disease risk factors such as metabolic syndrome, hypertension, insulin resistance, microalbuminuria, and endothelial dysfunction, among others. Here, we investigate the role of serum uric acid in preeclampsia in the development of CV complications., Materials and Methods: This was an observational case-control study that compared women with history of preeclampsia (n = 25) with age-matched controls with uncomplicated pregnancies (n = 20) who were followed for at least 5 years. Measurements included clinical and ambulatory blood pressure monitoring, ultrasound-measured flow-mediated dilatation (FMD), microalbuminuria, carotid intima-media thickness (CIMT) and serum uric acid, as well as clinical and demographic features. Cardiovascular disease risk factors were compared in women with and without previous preeclampsia., Results: At the time of index gestation, preeclamptic women had higher serum uric acid values (4.36 ± 0.61 vs 2.27 ± 0.38 mg/dL, P < 0.001). Five years after pregnancy, the patients who had preeclampsia were more likely to have hypertension and had higher serum uric acid levels, higher microalbuminuria and CIMT levels, and lower FMD values than did the patients who did not have preeclampsia. The 2 groups were similar with regard to various ambulatory blood pressure parameters. Univariate associates of FMD were history of preeclampsia and the current hypertension status. Microalbuminuria correlated with gestational uric acid levels (coefficient of correlation of 0.40, P = 0.01 for FMD and coefficient of correlation of 0.37, P = 0.01 for CIMT, respectively)., Conclusions: Preeclampsia might be a risk factor for the development of cardiovascular risk factors at least 5 years after index pregnancy. Serum uric acid and microalbuminuria may be mechanistic mediators of heightened risk, along with impaired endothelial function in preeclampsia.

Background: Cardiovascular disease (CVD) is the leading cause of mortality among subjects with type 2 diabetes (T2D), and diabetic retinopathy (DR) has been associated with an increased risk for CVD. The present study was designed to test the concept that T2D patients with DR, but without previous cardiovascular (CV) events and with normal renal function, have an increased atherosclerotic burden compared with patients without DR., Methods: A cross-sectional study was performed using patients with normal renal function (estimated glomerular filtration rate (eGFR) >60 ml/min) and without previous CV events. A total of 312 patients (men, 51%; mean age, 57 yrs; age range 40-75 yrs) were included in the study; 153 (49%) of the patients had DR. B-mode carotid ultrasound imaging was performed for all of the study subjects to measure the carotid intima-media thickness (cIMT) and carotid plaques in the common carotid artery (CCA), bifurcation and internal carotid artery (ICA)., Results: The percentage of carotid plaques in T2D patients with DR was higher than in T2D patients without DR (68% vs. 52.2%, p = 0.0045), and patients with DR had a higher prevalence of ≥2 carotid plaques (44.4% vs. 21.4%; p < 0.0001). No differences were observed in the cIMT measured at different carotid regions between the patients with or without DR. Using multivariate logistic regression (adjustment for major risk factors for atherosclerosis), DR was independently associated with mean-internal cIMT (p = 0.0176), with the presence of carotid plaques (p = 0.0366) and with carotid plaque burden (≥2 plaques; p < 0.0001)., Conclusions: The present study shows that DR in T2D patients without CVD and with normal renal function is associated with a higher atherosclerotic burden (presence and number of plaques) in the carotid arteries. These patients may be at a higher risk for future CV events; therefore, an ultrasound examination of the carotid arteries should be considered in patients with DR for more careful and individualised CV assessment and follow-up.

Background and Purpose: Carotid artery intima-media thickness (IMT) and plaque are noninvasive markers of subclinical arterial injury that predict incident cardiovascular disease. We evaluated predictors of longitudinal changes in IMT and new plaque during a decade in a longitudinal multiethnic cohort., Methods: Carotid IMT and plaque were evaluated in Multi-Ethnic Study of Atherosclerosis (MESA) participants at exams 1 and 5, a mean (standard deviation) of 9.4 (0.5) years later. Far wall carotid IMT was measured in both common and internal carotid arteries. A plaque score was calculated from all carotid segments. Mixed-effects longitudinal and multivariate regression models evaluated associations of baseline risk factors and time-updated medication use with IMT progression and plaque formation., Results: The 3441 MESA participants were aged 60.3 (9.4) years (53% women; 26% blacks, 22% Hispanic, 13% Chinese); 1620 (47%) had carotid plaque. Mean common carotid artery IMT progression was 11.8 (12.8) μm/year, and 1923 (56%) subjects developed new plaque. IMT progressed more slowly in Chinese (β=-2.89; P=0.001) and Hispanic participants (β=-1.81; P=0.02), and with higher baseline high-density lipoprotein cholesterol (per 5 mg/dL; β=-0.22; P=0.03), antihypertensive use (β=-2.06; P=0.0004), and time on antihypertensive medications (years; β=-0.29; P<0.0001). Traditional risk factors were associated with new plaque formation, with strong associations for cigarette use (odds ratio, 2.31; P<0.0001) and protection by black ethnicity (odds ratio, 0.68; P<0.0001)., Conclusions: In a large, multiethnic cohort with a decade of follow-up, ethnicity was a strong, independent predictor of carotid IMT and plaque progression. Antihypertensive medication use was associated with less subclinical disease progression., (© 2014 American Heart Association, Inc.)

Background: Adult post-coarctectomy patients (CoA) demonstrate increased cardiovascular morbidity and mortality. The carotid intima-media thickness (CIMT), a marker for atherosclerosis, is increased in CoA. The aim was to evaluate the predictive value of CIMT for cardiovascular events., Methods and Results: Consecutive CoA patients were prospectively studied during 10.1±0.7 years follow-up. At baseline and follow-up echocardiography, MRI imaging and CIMT imaging were performed, while cardiovascular events were registered. CIMT data were compared with controls. The composite endpoint included: myocardial infarction, cerebrovascular events (CVAs), and (sudden) cardiac death. 160 CoA patients were studied (median age 31.7 (18-74 years), 64% male). Events occurred in 11 patients (7%), five (3%) with myocardial infarction, four (2.5%) with an ischemic CVA and two (1%) died suddenly. An increased CIMT (≥0.8 mm) (HR=15.44, P=<0.001) was predictive for the occurrence of cardiovascular events. Baseline CIMT was increased in CoA compared to controls (0.64±0.12 mm vs 0.57±0.07 mm, P=0.005). CIMT progression rates were similar (0.0091±0.016 mm/year vs 0.0097±0.018 mm/year, P=0.84). Signs of atherosclerosis occurred significantly earlier in CoA patients., Conclusion: The contemporary cardiovascular event rate in CoA is 11% in 10 years. Atherosclerosis seems to appear earlier in CoA patients as compared to controls. CoA patients with a CIMT exceeding 0.8mm have a fifteen fold higher cardiovascular risk. CIMT seems to be a useful tool for cardiovascular risk assessment in CoA., (Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.)

Background: The presence of cardiovascular risk factors during the menopausal transition could be critical in the development of atherosclerosis. In the present study, we evaluated whether the menopausal transition has impact on traditional and newly discussed risk factors., Methods: Six hundred ninety nine women from population-based study underwent ultrasound measurement of the intima-media thickness of the common carotid arteries (CIMT) - Prague Pre and Postmenopausal Females study (3PMFs). In addition, 40 women selected according to reproductive and smoking status were examined with regard to number of circulating endothelial progenitor cells, markers of reverse cholesterol transport and sex hormones, including their fluctuation - Hormone Variability study (HVs)., Results: Age, smoking, body mass index, systolic blood pressure and HDL cholesterol were independently associated with the CIMT in 3PMFs group. The increase in the CIMT with age was markedly steeper in current/past smokers than in non-smokers among perimenopausal women (p for equality of slopes=0.005). This difference was not observed in premenopausal and menopausal women. In the HVs group, endothelial progenitor cells and reverse cholesterol transport were substantially higher while triglycerides and fluctuation of free testosterone were lower in non-smokers than in smokers in menopausal transition. In contrast, in menopausal women, the fluctuation of free testosterone was higher in non-smokers; no other differences between smokers and non-smokers were detected., Conclusions: These results suggest that atherogenic effect of smoking may be enhanced during menopausal transition. The mechanism could be impaired reparative vascular processes, impaired reverse cholesterol transport and rapidly changing status of sex hormones., (Copyright © 2012 Elsevier Ireland Ltd.

Background: Carotid intima-media thickness (CIMT) and carotid plaques represent preclinical markers of atherosclerosis. We sought to describe predictors of CIMT and carotid plaques, including early life growth, in a young urban Indian cohort free of clinical cardiovascular disease (CVD)., Methods: In 2006-2009, we performed B-mode carotid ultrasound on 600 participants (mean [SD] age 36 [1.1] years; 45% women) from the New Delhi Birth Cohort to evaluate CIMT and carotid plaques (>1mm). Height and weight were recorded at birth, 2 and 11 years of age. Data on CVD risk factors, anthropometry, medical history, socio-economic position, and lifestyle habits were collected in 1998-2002., Results: Mean (SD) CIMT for men and women was 0.91 (0.12) and 0.86 (0.13) mm, respectively. Carotid plaque was present in 33% of men and 26% of women. Waist circumference in 1998-2002 was positively associated with CIMT (β coefficient 0.26 mm [0.17, 0.36] per SD) and carotid plaque (OR 1.27 [1.06,1.52] per SD) in 2006-2009. Higher triglycerides, PAI-1, insulin resistance, and diastolic blood pressure, metabolic syndrome, and lower HDL-cholesterol and physical activity predicted higher CIMT and/or plaque (p<0.05). Longer length at 2 years was associated with higher CIMT (p<0.05). These associations were attenuated after adjusting for adult waist circumference., Conclusions: These are the first prospective data from India showing that early life growth, adult socio-demographics, and CVD risk factors predict future CIMT and/or carotid plaque. These relationships appear primarily mediated through central adiposity, highlighting the importance of maintaining a healthy weight in early adulthood to prevent CVD., (Copyright © 2012 Elsevier Ireland Ltd.

Background: India is undergoing rapid epidemiological and nutritional transition largely as a consequence of rapid urbanisation. We investigated conventional and novel cardiovascular risk factors in rural and urban Indian men and studied their association with markers of vascular damage., Methods: We randomly selected and studied 149 rural, 142 urban slum residents and 150 urban middle class middle aged Indian men. We measured conventional (obesity, blood pressure, lipids, smoking habits) and novel (proinflammatory and prothrombotic factors) cardiovascular risk factors and markers of vascular damage (carotid intima media thickness (IMT), von Willebrand Factor (vWF), e-selectin)., Results: There was a progressive increase in most of the conventional cardiovascular (CV) risk factors from rural to slum to urban middle class men. Plasminogen activator inhibitor-1 (PAI-1), platelet count, total homocysteine and C-reactive protein showed similar patterns. Carotid IMT was similar in the three groups; vWF was highest in rural and e-selectin in slum men. Adjusting for location, age explained 17%, obesity 3% and conventional risk factors 1% of the variance in carotid IMT, whilst novel cardiovascular risk factors were without any significant impact., Conclusions: Urbanisation increases obesity related as well as prothrombotic and proinflammatory CV risk factors in Indian men, but appears not to impact on IMT., (Copyright © 2011 Elsevier Ireland Ltd.

Background: Expansive remodelling is the process of compensatory arterial enlargement in response to atherosclerotic stimuli. The genetic determinants of this process are poorly characterized., Methods: Genetic association analyses of inter-adventitial common carotid artery diameter (ICCAD) in the IMPROVE study (n = 3427) using the Illumina 200k Metabochip was performed. Single nucleotide polymorphisms (SNPs) that met array-wide significance were taken forward for analysis in three further studies (n = 5704), and tested for association with Abdominal Aortic Aneurysm (AAA)., Results: rs3768445 on Chromosome 1q24.3, in a cluster of protein coding genes (DNM3, PIGC, C1orf105) was associated with larger ICCAD in the IMPROVE study. For each copy of the rare allele carried, ICCAD was on average 0.13 mm greater (95% CI 0.08-0.18 mm, P = 8.2 × 10(-8)). A proxy SNP (rs4916251, R(2) = 0.99) did not, however, show association with ICCAD in three follow-up studies (P for replication = 0.29). There was evidence of interaction between carotid intima-media thickness (CIMT) and rs4916251 on ICCAD in two of the cohorts studies suggesting that it plays a role in the remodelling response to atherosclerosis. In meta-analysis of 5 case-control studies pooling data from 5007 cases and 43,630 controls, rs4916251 was associated with presence of AAA 1.10, 95% CI 1.03-1.17, p = 2.8 × 10(-3), I(2) = 18.8, Q = 0.30). A proxy SNP, rs4916251 was also associated with increased expression of PIGC in aortic tissue, suggesting that this may the mechanism by which this locus affects vascular remodelling., Conclusions: Common variation at 1q24.3 is associated with expansive vascular remodelling and risk of AAA. These findings support a hypothesis that pathways involved in systemic vascular remodelling play a role in AAA development., (Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.)

Background and Purpose: Data on risk factors for progression of intima-media thickness (IMT) and plaque are scarce. The objective was to determine long-term risk factors for total plaque area (TPA) and IMT as well as risk factors for progression (ΔTPA and ΔIMT)., Methods: Subjects were 1307 men and 1436 women who participated in a longitudinal population-based study with ultrasound examination of the right carotid artery at baseline and after 13 years of follow-up. Total cholesterol, high-density lipoprotein cholesterol, blood pressure, body mass index, and information about smoking habits, prevalent diabetes, and cardiovascular disease were obtained at baseline. Carotid atherosclerosis was assessed as TPA and mean IMT of plaque-free segments of the common carotid artery. Associations between z-scores of risk factors and carotid atherosclerosis were assessed in multiple linear regression models., Results: In multivariable models, total cholesterol, systolic blood pressure, and smoking were stronger predictors of follow-up TPA than of IMT, whereas sex and age were stronger predictors of IMT. Total cholesterol (standardized β=0.081), systolic blood pressure (standardized β=0.062), and smoking (standardized β=0.107) were significant predictors of ΔTPA, whereas only total cholesterol (standardized β=0.084) was an independent predictor of ΔIMT. The variance explained by traditional cardiovascular risk factors was somewhat greater for TPA than for IMT., Conclusions: The cardiovascular risk factors total cholesterol, smoking, and systolic blood pressure were stronger long-term predictors of TPA and TPA progression than for IMT and IMT progression.

Our aim in this study was to assess the relationship between the state of cerebral vessels and the risk of conversion from mild cognitive impairment (MCI) to Alzheimer's disease (AD). We included 117 MCI patients. They underwent an ultrasonographic assessment of common carotid arteries intima-media thickness (IMT) and carotid plaque index. Cerebrovascular reactivity to hypercapnia in the middle cerebral arteries was calculated with the Breath-Holding Index (BHI). After a 12-month follow-up period, neuropsychological examinations demonstrated a progression to dementia in 21 patients. Pathological values of BHI and IMT significantly increased the risk of conversion (BHI: odds ratio, 5.80; 95% confidence interval, 1.83-18.37, p < 0.05; IMT: odds ratio, 3.08; 95% confidence interval, 1.02-9.33; p < 0.05, multinomial logistic regression analysis). Comparison between patients with all normal values and those with the simultaneous alteration of the 2 vascular indexes showed an increase in the risk of conversion from 9% to 33% (ordinal regression analysis). Our findings show that alterations of cerebral vessel functional and anatomic status increase the risk of conversion from MCI to dementia., (Copyright © 2012 IBRO. Published by Elsevier Inc.

Background: Cardiovascular disease morbidity-mortality is greater in people with type 2 diabetes mellitus or metabolic syndrome. The purpose of this study was to evaluate the yearly evolution of organ damage markers in diabetes or metabolic syndrome, and to analyze the associated factors., Methods: An observational prospective study was carried out in the primary care setting, involving 112 patients: 68 diabetics and 44 subjects with metabolic syndrome, subjected to 12 months of follow-up., Measurements: traditional cardiovascular risk factors (blood pressure, blood glucose, lipids, smoking, body mass index (BMI) and) and non-traditional risk factors (waist circumference, hsC Reactive Protein and fibrinogen); subclinical vascular (carotid intima-media thickness, pulse wave velocity and ankle/brachial index), cardiac (Cornell voltage-duration product), renal organ damage (creatinine, glomerular filtration and albumin/creatinine index), and antihypertensive and lipid-lowering drugs., Results: At baseline, the diabetics presented a mean age of 59.9 years, versus 55.2 years in the subjects with metabolic syndrome (p = 0.03). Diastolic blood pressure, total cholesterol and HDL-cholesterol were lower among the patients with diabetes, while blood glucose and HbA1c, as well as antihypertensive and lipid-lowering drug use, were greater. At evaluation after one year, the diabetics showed a decrease in BMI (-0.39), diastolic blood pressure (-3.59), and an increase in fibrinogen (30.23 mg/dL), ankle/brachial index (0.07) and the number of patients with ankle/brachial index pathologic decreased in 6. In turn, the patients with metabolic syndrome showed an increase in HDL-cholesterol (1-91 mg/dL), fibrinogen (25.54 mg/dL), Cornell voltage-duration product (184.22 mm/ms), ankle/brachial index (0.05) and the use of antihypertensive and lipid-lowering drugs, and a reduction in serum glucose (3.74 mg/dL), HOMA, systolic (-6.76 mmHg), diastolic blood pressure (-3.29 mmHg), and pulse wave velocity (-0.72 m/s). The variable that best predicted a decrease in pulse wave velocity in subjects with metabolic syndrome was seen to be an increase in antihypertensive drug use., Conclusions: The annual assessment of cardiovascular risk factors and the decrease in pulse wave velocity was more favorable in the patients with metabolic syndrome, probably influenced by the increased percentage of subjects treated with antihypertensive and lipid lowering drugs in this group.
