Associations between emotional support and cardiovascular risk factors and subclinical atherosclerosis in middle-age

Objective To test the hypothesis of low emotional support being associated with lifestyle and biomedical cardiovascular disease (CVD) risk factors, estimated risk of CVD morbidity and mortality, and subclinical atherosclerosis in middle-aged healthy adults. Methods and measures Cross-sectional data were obtained from participants aged 40–60 years who had one or more conventional CVD risk factor. They underwent assessment based on questionnaires, clinical examination, blood sampling, and carotid ultrasound of plaque formation and carotid intima-media wall thickness (cIMT). Based on the Interview Schedule for Social Interaction, the participants were categorised as either low in emotional support (n = 884) or as a referent (n = 2570). Logistic regression analyses were conducted to study the associations. Results Logistic regression analyses showed that low emotional support was significantly associated with smoking, alcohol consumption and physical inactivity (OR = 1.53 − 1.94), estimated risk of CVD morbidity and mortality (OR = 1.56 − 1.68), and plaque formation (OR = 1.39). No significant associations were found regarding biomedical CVD risk factors or cIMT. Conclusion The findings suggest that low social support is associated with lifestyle CVD risk factors, estimated risk of CVD morbidity and mortality, and subclinical atherosclerosis in middle-aged healthy adults, encouraging causal evaluation with longitudinal data investigating an impact of emotional support on mechanisms underlying CVD.

A Study of Oxidative Stress, Inflammation, and Endothelial Dysfunction in Diabetic and Nondiabetic Chronic Kidney Disease Pre-Dialysis Patients.

Oxidative stress, inflammation, and endothelial dysfunction represent a key triad for the development and progression of atherosclerosis. Due to chronic low-grade inflammation in chronic kidney disease (CKD), concentrations of various inflammatory, endothelial, and oxidative stress markers are elevated, increasing the risk of atherosclerosis. The present study was undertaken to compare oxidative stress, inflammation, and endothelial dysfunction in diabetic and nondiabetic CKD pre-dialysis patients. This was an observational study on 120 CKD pre-dialysis patients: 60 with diabetes and 60 without diabetes. Markers of oxidative stress were measured in blood - malondialdehyde (MDA), ferric reducing ability of plasma (FRAP), paroxonase-1 (PON-1), ischemia-modified albumin (IMA); inflammation - interleukin-6 (IL-6), high-sensitivity C-reactive protein (hsCRP); and endothelial dysfunction - nitric oxide (NO), carotid wall intima-media thickness (CIMT). Comparisons between the two groups for continuous variables were made with the Student's unpaired t-test or Mann-Whitney test and for categorical values with χ2-test, as appropriate. MDA, IMA, IL-6, hsCRP, NO, and CIMT were significantly higher, while FRAP and PON-1 were significantly lower in the diabetic group when compared to nondiabetic group (P < 0.001). The number of atherosclerotic plaques was also significantly higher in the diabetic group compared to nondiabetic group. Our study showed increased oxidative stress, inflammation, endothelial dysfunction, and atherosclerosis in diabetic CKD pre-dialysis patients when compared to nondiabetic CKD pre-dialysis patients and in late stages when compared to early stages of CKD in both groups, indicating increased cardiovascular risk in late stages and diabetic CKD pre-dialysis patients.

Increased carotid intima-media thickness and reduced health-related physical fitness in children and adolescents with coarctation of the aorta

BackgroundCoarctation of the Aorta (CoA) was assumed to be one of the congenital heart defects not associated with major long-term sequels. Meanwhile, it is known that there are long-term cardiovascular consequences. This study investigates the functional outcome measures in children with CoA. Methods77 children (40.3% girls, 13.1 ± 3.3 years) with CoA were examined for their functional outcome measures and compared to healthy controls (CG). Carotid Intima-Media wall thickness (cIMT) was measured by ultrasound of the common carotid artery. In addition, Health-related Physical Fitness (HrPF) was assessed by five tasks of the FITNESSGRAM® and health-related quality of life (HrQoL) was analyzed with a self-report questionnaire (KINDL-R). ResultsAfter adjustment for age and sex and in comparison to the CG, the CoA patients showed structural changes in cIMT (CoA: 0.480 ± 0.043 mm vs CG: 0.465 ± 0.033 mm; p = 0.002) and significantly lower HrPF (z-score −0.46 ± 0.7; p < 0.001; 32nd percentile). HrQoL in children with CoA was significantly better in comparison to CG (p = 0.020). ConclusionEarly onset of structural changes of the cIMT in children with CoA could be shown. These structural changes in combination with hypertension, which often is associated with CoA, should be the focus of structured follow-up during childhood. The children with CoA showed impaired HrPF in comparison, where the promotion of physical activity should be the key factor for improvement. Encouragingly they showed better HrQoL.

Carotid Intima-Media Thickness Percentiles in Adolescence and Young Adulthood and Their Association With Obesity and Hypertensive Blood Pressure in a Population Cohort.

This study aimed to derive carotid intima media thickness (CIMT) percentiles from a population-based sample of adolescents and young adults using improved technology, standardization and quality control, and to investigate the association of CIMT with hypertensive blood pressure (BP) and obesity. Four thousand seven hundred nine 14- to 28-year-old participants of the German KiGGS cohort 11-year follow-up, which was based on a nationwide population sample, had B-mode ultrasound CIMT measurement with semi-automated edge-detection and automatic ECG-gated real-time quality control. CIMT percentiles were estimated from far wall CIMT during 2 to 6 heart cycles using the GAMLSS statistical model. Hypertensive BP, overweight, obesity, and a risk score from added Z scores of triglycerides, total/HDL (high-density lipoprotein)-cholesterol ratio, and glycated hemoglobin were based on standardized measurements at baseline and follow-up. CIMT differed by sex at all ages, furthermore by age and height in a nonlinear fashion. Percentiles were estimated simultaneously by age and height. Hypertensive BP and obesity were associated cross-sectionally and longitudinally with a higher risk of CIMT ≥75th percentile in log-binomial regression models adjusted for age, sex, height, current smoking, and cardiovascular risk score. For CIMT ≥90th percentile, the relative risk effect estimates were consistently >1 but often had large confidence intervals including 1, largest adjusted relative risk 3.37 (95% CI, 1.41-8.04) for the combination of hypertensive BP and obesity at follow-up. Based on state-of-the-art measurements and statistical techniques, these population-based CIMT percentiles by sex, age and height add unbiased evidence for the association of subclinical atherosclerosis with hypertensive BP and obesity in the young.

SCORE2 Assessment in the Calculation of Cardiovascular Risk in Patients with Rheumatoid Arthritis.

Patients with rheumatoid arthritis (RA) are at increased risk for cardiovascular disease (CVD). Risk chart algorithms, such as the Systematic Coronary Risk Assessment (SCORE), often underestimate the risk of CVD in patients with RA. In this sense, the use of noninvasive tools, such as the carotid ultrasound, has made it possible to identify RA patients at high risk of CVD who had subclinical atherosclerosis disease and who had been included in the low or moderate CVD risk categories when the SCORE risk tables were applied. The 2003 SCORE calculator was recently updated to a new prediction model: SCORE2. This new algorithm improves the identification of individuals from the general population at high risk of developing CVD in Europe. Our objective was to compare the predictive capacity between the original SCORE and the new SCORE2 to identify RA patients with subclinical atherosclerosis and, consequently, high risk of CVD. 1168 non-diabetic patients with RA and age > 40 years were recruited. Subclinical atherosclerosis was searched for by carotid ultrasound. The presence of carotid plaque and the carotid intima media wall thickness (cIMT) were evaluated. SCORE and SCORE2 were also calculated. The relationships of SCORE and SCORE2 to each other and to the presence of subclinical carotid atherosclerosis were studied. The correlation between SCORE and SCORE2 was found to be high in patients with RA (Spearman’s Rho = 0.961, p < 0.001). Both SCORE (Spearman’s Rho = 0.524) and SCORE2 (Spearman’s Rho = 0.521) were similarly correlated with cIMT (p = 0.92). Likewise, both calculators showed significant and comparable discriminations for the presence of carotid plaque: SCORE AUC 0.781 (95%CI 0.755–0.807) and SCORE2 AUC 0.774 (95%CI 0.748–0.801). Using SCORE, 80% and 20% of the patients were in the low or moderate and high or very high CVD risk categories, respectively. However, when the same categories were evaluated using SCORE2, the percentages were different (58% and 42%, respectively). Consequently, the number of RA patients included in the high or very high CVD risk categories was significantly higher with SCORE2 compared to the original SCORE. (p < 0.001). In conclusion, although predictive capacity for the presence of carotid plaque is equivalent between SCORE and SCORE2, SCORE2 identifies a significantly higher proportion of patients with RA who are at high or very high risk of CVD.

Adiposity Phenotypes and Subclinical Atherosclerosis in Adults from Sub-Saharan Africa: An H3Africa AWI-Gen Study.

Background:Obesity and adipose tissue distribution contribute to an increased risk of cardiovascular disease (CVD) by promoting atherosclerosis. This association has been poorly studied in sub–Saharan Africa (SSA) despite the rising prevalence of cardiovascular disease.Objectives:We determined the association between various adiposity phenotypes and carotid intima–media thickness (CIMT), a proxy of subclinical atherosclerosis, in a large SSA population.Methods:A population–based cross–sectional study was performed from 2013–2016 in Burkina Faso, Ghana, Kenya and South Africa. Body mass index (BMI), waist (WC), hip circumferences (HC), visceral (VAT) and subcutaneous adipose tissue (SCAT) using B-mode ultrasound were measured. Ultrasonography of left and right far wall CIMT of the common carotid artery was used as an indicator of subclinical atherosclerosis. Individual participant data meta–analyses were used to determine the associations between adiposity phenotypes and CIMT in the pooled sample while adjusted multivariable linear regression analyses were used for site specific analyses.Results:Data were obtained from 9,010 adults (50.3% women and a mean age of 50± 6years). Men had higher levels of visceral fat than women while women had higher BMI, waist and hip circumference and subcutaneous fat than men at all sites except Burkina Faso. In the pooled analyses, BMI (β–value [95% CIs]: 19.5 [16.8, 22.3] μm) showed the strongest relationship with CIMT followed by VAT (5.86 [4.65, 7.07] μm), SCAT (5.00 [2.85, 7.15] μm), WC (1.27 [1.09, 1.44] μm) and HC (1.23 [1.04, 1.42] μm). Stronger associations were observed in men than in women.Conclusion:Obesity within SSA will likely result in higher levels of atherosclerosis and promote the occurrence of cardio- and cerebrovascular events, especially in males, unless addressed through primary prevention of obesity in both rural and urban communities across Africa. The inverse association of VAT with CIMT in Burkina Faso and Ghana requires further investigation.HighlightsAll adiposity phenotypes were positively associated with common carotid intima–media thickness (CIMT) in the entire cohort (pooled analyses).BMI had the strongest association with CIMT compared to other phenotypes.The magnitude of association between adiposity phenotypes and CIMT was higher in men than in women.Subcutaneous adipose tissue was inversely associated with CIMT only in women.An unexpected finding was the inverse association of visceral adipose tissue with CIMT in Burkina Faso and Ghana.

Subclinical atherosclerotic disease in ankylosing spondylitis and non-radiographic axial spondyloarthritis. A multicenter study on 806 patients

ObjectivesTo compare the atherosclerosis disease burden between ankylosing spondylitis (AS) and non-radiographic (nr) axial spondyloarthritis (axSpA) and establish a model that allows to identify high-cardiovascular (CV) risk in axial spondyloarthritis patients. MethodsCross-sectional study from the AtheSpAin cohort, a Spanish multicenter cohort aimed to study atherosclerosis in axSpA. Carotid ultrasound (US) was performed to determine the carotid intima-media wall thickness (cIMT) and detect the presence of carotid plaques. The European cardiovascular disease risk assessment model, the Systematic COronary Risk Evaluation (SCORE), was also applied. ResultsA set of 639 patients with AS and 167 patients with nr-axSpA without history of CV events were recruited. AS patients were older showing more CV risk factors and higher values of C reactive protein and erythrocyte sedimentation rate (ESR) than those with nr-axSpA. However, no difference in the prevalence of carotid plaques or in the cIMT was found between both groups in the adjusted analysis. The percentage of patients reclassified from the low and moderate CV risk categories to the very high-risk category due to the presence of carotid plaques was comparable in AS and nr-axSpA (10.7% versus 10.1% and 40.5% versus 45.5%, respectively). A model containing age, BASFI and ESR applied to moderate risk axSpA patients identified 41% of these patients as having very high-risk patients with high specificity (88%). ConclusionThe atherosclerosis burden is similar in nr-axSpA and AS. As occurred for AS, more than 40% of axSpA patients included in the category of moderate CV risk according to the SCORE are reclassified into very high risk after carotid US, and a clinically relevant proportion of them can be detected by applying a model containing age, BASFI and ESR.

Westernization of Lifestyle and Atherosclerosis in the Japanese: Lessons from the Hawaii - Los Angeles - Hiroshima Study.

Japanese Americans include Japanese individuals migrating from Japan to the United States (first-generation Japanese Americans [JA-1]) and their offspring (second- or later-generation Japanese Americans [JA-2]). Although Japanese Americans share their genetic predisposition with the Japanese, their lifestyles have been westernized rapidly and extensively. We conducted a medical survey for atherosclerosis among Japanese Americans living in Hawaii and Los Angeles and native Japanese living in Hiroshima for 50 years since 1970 (the Hawaii–Los Angeles–Hiroshima Study) and obtained the following results:(1) In the 1990s, a westernized lifestyle induced hyperlipidemia among Japanese Americans, and based on the evaluation of the carotid artery intima-media wall thickness (IMT), atherosclerosis was apparently more advanced in Japanese Americans than in native Japanese. In addition, the advancement of atherosclerosis corresponded to the degree of westernization of lifestyles in JA-1 and JA-2.(2) In the 2010s, the serum total cholesterol and low-density lipoprotein cholesterol levels in native Japanese were significantly higher than those in Japanese Americans, and the difference in the progression of carotid artery IMT was smaller between native Japanese and Japanese Americans.(3) Maintaining a healthy Japanese lifestyle since childhood may suppress future worsening of risk factors for atherosclerosis (such as obesity and diabetes mellitus) and contribute to atherosclerosis prevention in the Japanese.

Assessment of Periodontal Status Based on Carotid Artery Intima Media Thickness.

Atherosclerosis is a devastating disease worldwide since it is the most frequent cause of myocardial infarction, stroke, renal failure, peripheral vascular disease and perhaps dementia. There is a well-documented evidence supporting the association between clinical/subclinical atherosclerosis and periodontitis. Carotid intima media wall thickness (CIMT) is a histopathologically validated marker of atherosclerosis. This study's purpose was to assess periodontal status based on carotid artery intima media thickness. A cross-sectional study was carried out among subjects who visited the Care Hospital, Nampally Hyderabad for CIMT test. Oral hygiene status was evaluated using Simplified Oral Hygiene Index and periodontal health status was measured using modified World Health Organization (WHO) Oral Health Assessment form, 1997. The data was analysed using Statistical Package for Social Sciences (SPSS) version 21.0. The proportions and mean scores were compared using chi-square test, Mann-Whitney U test and analysis of variance (ANOVA). Logistic regression analysis determined the relationship between periodontitis, as an independent variable and other variables with CIMT. P < 0.05 was considered statistically significant. A total of 600 individuals were classified based on CIMT thickness ≤ 1 mm (292; 48.6%) and CIMT > 1 mm (308; 51.3%) according to variables. Significantly higher mean scores were observed for all oral parameters among subjects with CIMT > 1 mm aged > 45 years and among males (p ≤ 0.05*). Logistic regression analysis showed that increasing age group, ie,> 45 years (OR 3.5), males (OR 2.02), university education (OR 2.99), no history of previous dental visit (OR 3.71); and visit ≥ 1 year (OR 0.76) and previous history of tobacco (OR 1.13) and alcohol use (OR 1.65), poor OHI-S (OR 8.00), Community Periodontal Index (CPI) with Code 3, 4 (OR 4.41) and loss of attachment (LOA) with Code 2 (OR 3.05) and Code 3 (OR 5.80) had significantly higher odds among individuals with subjects with CIMT > 1 mm compared to their counterparts (p ≤ 0.05*). The results of the study concluded that periodontal disease and poor oral hygiene were more severe among the subjects with CIMT > 1 mm. To halt the progression of increasing CIMT, preventive oral health programmes need to be integrated in the cardiac setting with established dental referral which can bring out positive health behaviours.

Subclinical Atherosclerosis and Atherogenic Index of Plasma in Lichen Planus Patients- A Comparative Cross-sectional Study

Introduction: Lichen Planus (LP) is an idiopathic and chronic inflammatory disease that affects the skin and the mucous membranes, and studies have proven its association with increased risk for Cardiovascular (CV) diseases. Subclinical atherosclerosis and Atherogenic Index of Plasma (AIP) are strong predictors of CV risk. Aim: The primary aim of this study was the evaluation of Common Carotid artery mean Intima-Media wall Thickness (CIMT) and AIP which are predictors of CV risk in patients with LP. Materials and Methods: Fifty patients with LP and fifty age, gender and Body Mass Index (BMI) matched healthy controls (from the general population without the disease) were included in the study. CIMT was measured using ultrasound. Lipid profile was calculated by biochemical analysis. AIP was calculated from lipid profile using validated formula. Data was analysed using SPSS version 16.0 software. Results: Compared to healthy controls, patients had significantly higher CIMT. A 28% of patients had subclinical atherosclerosis compared to 2% of controls (p&lt;0.001). Dyslipidemia was detected in 42% of patients and only 10% of controls (p&lt;0.001). AIP was significantly elevated in LP patients compared to controls (p&lt;0.001). A 36% of patients had high CV risk according to AIP versus 8% of controls. The 80% of controls had low CV risk versus 48% of patients (p&lt;0.001). Conclusion: LP patients were found to have increased CV risk. CIMT, lipid profile and AIP can serve as important diagnostic markers of CV risk. Educating the patients about such a risk will enable them to follow lifestyle modifications so as to prevent further complications and morbidity.

P4450Atherosclerosis in women with systemic lupus erythematosus with and without nephritis

Abstract Background Nephritis in systemic lupus erythematosus (SLE) is a factor contributing to early development of atherosclerosis (AS). Objectives The aim of the study is to determine differences in cardiovascular risk factors and AS in SLE pts with and without lupus nephritis (LN). Methods The study included 162 females, age 35 [26–43] years (median [interquartile range 25–75%])) with SLE (ACR,1997). We divided SLE pts on two groups, comparable in age: the 1st group is the pts with LN (n=84, 52%), the 2nd - without LN (n=78, 48%). We considered traditional factors of cardiovascular disease (CVD): (smoking, family history of CVD, blood pressure, cholesterol (total, HDL, LDL) and triglyceride (TG) levels, body mass index, diabetes mellitus) and SLE-related factors (age at onset, duration, clinical features, SLE Disease Activity Index (SLEDAI-2K) and the Systemic Lupus International Collaborating Clinics damage index (SLICC/DI), treatment with steroids); intima-media thickness (IMT) and the 10-year risk for coronary events. Carotid intima-media wall thickness of common carotid arteries was measured by high resolution B-mode ultrasound. The 10-year risk for coronary events was estimated by the Framingham risk equation. Results Median SLE duration was 8,0 [2,3–17,0] years, SLEDAI 2K – 8 [3–16], SLICC/DI score – 2 [0–3], duration of prednisone treatment – 72 [26–141] months. SLE pts from the 1st group had higher prevalence of hypertension (61% vs 36%, p&lt;0,01), systolic blood pressure (130 [110–150] vs 120 [110–130]mm Hg, p&lt;0,01), diastolic blood pressure (80 [70–95] vs 70 [70–80] mm Hg, p&lt;0,05), TG concentration (136 [98–184] vs 100 [61–162] mg/dl, p&lt;0,01), Framingham Risk Score (5 [1–30] vs 1 [1–27]%, p&lt;0,05), SLEDAI-2K (12 [5–19] vs 4 [2–10], p&lt;0,ehz745.08501), SLICC/DI score (2 [0–4] vs 0 [0–2], p&lt;0,01), prednisone therapy duration (95 [26–192] vs 44 [14–98] months, p&lt;0,05), prednisone cumulative dose (34,4 [13,6–82,5] vs 15,7 [6,2–35,2] g, p&lt;0,001), mean IMT (0,73 [0,65–0,83] vs 0,67 [0,61–0,75] mm, p&lt;0,01), than the pts from the 2nd group. There is no difference in CVD frequency in these groups (17% vs 8%, p=0,084). Conclusions SLE patients with and without LN had no difference in frequency of clinical manifestations of AS (CVD), but had a greater value of mean IMT, Framingham Risk Score and a higher incidence of both traditional (hypertension, TG concentration) and SLE-related (disease activity, prednisone therapy) risk factors for AS.

Role of Carotid Ultrasound and Systematic Coronary Risk Evaluation Charts for the Cardiovascular Risk Stratification of Patients with Psoriatic Arthritis.

The assessment of the cardiovascular (CV) risk is recommended in patients with chronic inflammatory rheumatic diseases. The objectives of this study were to assess the CV risk profile in a cohort of patients with psoriatic arthritis (PsA), to determine the presence of subclinical cardiovascular disease by carotid ultrasound (US), and to study the association of CV disease to PsA characteristics. This was a cross-sectional multicentric descriptive study. The clinical CV risk was calculated with Systematic Coronary Risk Evaluation (SCORE) charts. Common carotid US was conducted to evaluate the carotid wall intima-media thickness and the presence of atheroma plaques. Patients were reclassified upon US results. Multivariate analyses were performed to identify associations of US carotid abnormalities with the classical CV risk factors and PsA characteristics. The study included 176 patients with PsA. The SCORE-estimated CV risk was intermediate in 65.3% of the patients. In the US study, 32% of the patients had abnormalities, and 30.8% of the patients were upgraded and reclassified as very high risk owing to the presence of atheroma. Subclinical CV disease was associated with age and dyslipidemia but not with other risk factors. It was associated with axial disease in the subgroup with intermediate risk, and with C-reactive protein levels in patients with high risk. Many patients with PsA have clinical estimated intermediate or high risk of a fatal CV event. A carotid US study detects subclinical vascular disease and may be useful to depict the real risk. The presence of atheroma is only partially explained by the classic CV risk factors.

Relationship between plasma fibroblast growth factor-23 and subclinical cardiovascular damages in children with primary hypertension

Objective: To examine the plasma fibroblast growth factor-23 (FGF-23) concentration in children with primary hypertension and to investigate the association between plasma FGF-23 and subclinical cardiovascular damages,and to identify its predictive value for diagnosis. Methods: With prospective study,77 patients (61 males and 16 females) who were diagnosed as primary hypertension with the average age of (11.8±2.2) years were enrolled with informed consent in Children's Hospital,Capital Institute of Pediatrics from October 2016 to December 2017. Carotid wall intima-media thickness (cIMT) measured by Doppler ultrasound and left ventricular hypertrophy (LVH) identified by echocardiography were assessed as parameters of subclinical cardiovascular damages. Patients were divided into increased cIMT group (n=18) and normal cIMT group (n=46) (64 patients with complete data of cIMT). According to left ventricular geometry,patients were divided into LVH group (n=27) and normal geometry group (n=50). Concentration of plasma FGF-23 was detected in all children by enzyme linked immunosorbent assay test. Mann-Whitney U test was used to compare plasma levels of FGF-23 between groups. Kendall's tau-b correlation coefficient was used to analyze the correlation between plasma FGF-23 and cIMT/LVH. Receiver operating characteristic (ROC) curve was used to analyze the value of plasma FGF-23 in the prediction of subclinical cardiovascular damage. Results: The concentration of plasma FGF-23 in the increased cIMT group was higher than that in the normal cIMT group (55.6 (46.2,63.5) vs. 48.6 (39.4, 57.3) ×10(3) RU/L, Z=-2.143, P=0.032) . Also, plasma FGF-23 showed positive correlation with cIMT(r=0.222, P=0.032). According to ROC curve analysis,the cutoff value of plasma FGF-23 for prediction of increased cIMT was 53.9×10(3) RU/L (55.6% sensitivity and 71.7% specificity). The concentration of plasma FGF-23 in the LVH group was significantly higher than that in normal geometry group (55.0 (46.8, 65.7) vs. 48.2 (39.5, 56.0)×10(3) RU/L, Z=-2.375, P=0.018). And,plasma FGF-23 was correlated positively with LVH (r=0.224, P=0.018). The concentration of plasma FGF-23 in patients with concentric remodeling (n=10) was significantly higher than that of the normal geometry group (56.9 (49.6, 66.3) vs. 48.2 (39.5,56.0) ×10(3) RU/L, Z=-2.093, P=0.036). According to ROC curve analysis,the cutoff value of plasma FGF-23 for prediction of LVH was 49.1×10(3) RU/L (70.4% sensitivity and 60.0% specificity). Conclusion: The concentration of plasma FGF-23 in children with primary hypertension was correlated positively with LVH and cIMT and had certain predictive value of diagnosis for subclinical cardiovascular damages.

Visualization of asymptomatic atherosclerotic disease for optimum cardiovascular prevention (VIPVIZA): a pragmatic, open-label, randomised controlled trial

Primary prevention of cardiovascular disease often fails because of poor adherence among practitioners and individuals to prevention guidelines. We aimed to investigate whether ultrasound-based pictorial information about subclinical carotid atherosclerosis, targeting both primary care physicians and individuals, improves prevention. Visualization of asymptomatic atherosclerotic disease for optimum cardiovascular prevention (VIPVIZA) is a pragmatic, open-label, randomised controlled trial that was integrated within the Västerbotten Intervention Programme, an ongoing population-based cardiovascular disease prevention programme in northern Sweden. Individuals aged 40, 50, or 60 years with one or more conventional risk factors were eligible to participate. Participants underwent clinical examination, blood sampling, and ultrasound assessment of carotid intima media wall thickness and plaque formation. Participants were randomly assigned 1:1 with a computer-generated randomisation list to an intervention group (pictorial representation of carotid ultrasound plus a nurse phone call to confirm understanding) or a control group (not informed). The primary outcomes, Framingham risk score (FRS) and European systematic coronary risk evaluation (SCORE), were assessed after 1 year among participants who were followed up. This study is registered with ClinicalTrials.gov, number NCT01849575. 3532 individuals were enrolled between April 29, 2013, and June 7, 2016, of which 1783 were randomly assigned to the control group and 1749 were assigned to the intervention group. 3175 participants completed the 1-year follow-up. At the 1-year follow-up, FRS and SCORE differed significantly between groups (FRS 1·07 [95% CI 0·11 to 2·03, p=0·0017] and SCORE 0·16 [0·02 to 0·30, p=0·0010]). FRS decreased from baseline to the 1-year follow-up in the intervention group and increased in the control group (-0·58 [95% CI -0·86 to -0·30] vs 0·35 [0·08 to 0·63]). SCORE increased in both groups (0·13 [95% CI 0·09 to 0·18] vs 0·27 [0·23 to 0·30]). This study provides evidence of the contributory role of pictorial presentation of silent atherosclerosis for prevention of cardiovascular disease. It supports further development of methods to reduce the major problem of low adherence to medication and lifestyle modification.

Clinical and subclinical cardiovascular disease in female SLE patients: Interplay between body mass index and bone mineral density

Background and aimsSince accelerated atherosclerosis has been reported in systemic lupus erythematosus (SLE), predictive biomarkers of cardiovascular disease (CVD) are needed. Among non-traditional risk factors, bone mineral density (BMD) has been related to CVD. However, its role in SLE remains controversial. This study aims to analyze the associations of subclinical atherosclerosis with traditional and non-traditional CV risk factors. Methods and resultsIn a cross-sectional study, atherosclerosis burden was compared between 112 female SLE patients and 31 controls. Plaque number and carotid intima-media wall thickness (cIMT) were assessed by ultrasonography. In a retrospective study, BMD determinations obtained 5-years before the ultrasonography assessment were analyzed in a subgroup of 62 patients. Plaque frequency was increased in SLE, even in patients without CV events or carotid wall thickening. cIMT was increased in patients with CVD, positively correlated with body mass index (BMI). Interestingly, a paradoxical effect of BMI on carotid parameters was observed. Whereas underweight patients (BMI < 20) showed increased prevalence of carotid plaques with low cIMT, those with BMI > 30 showed higher cIMT and plaque burden. Overweight patients (25 < BMI<30) exhibited both elevated cIMT and plaque number. BMI was an independent predictor of BMD. In our retrospective study, patients with either clinical or subclinical CVD exhibited lower BMD levels than their CV-free counterparts. A low lumbar spine BMD independently predicted CVD development after adjusting for confounders. ConclusionSLE was associated with a higher subclinical atherosclerosis burden, a bimodal effect being observed for BMI. Decreased BMD can be a CV risk biomarker in SLE.

Arousal index as a marker of carotid artery atherosclerosis in patients with obstructive sleep apnea syndrome.

It was shown in a previous cohort study that men with internal carotid artery (ICA) plaque, defined as focal wall thickness of ≥ 1.5mm, had a threefold higher risk of stroke than those without plaque. We examined the relationship between arousal indices and sleep stages in patients with obstructive sleep apnea syndrome (OSAS) and carotid atherosclerosis. Carotid atherosclerosis severity was evaluated using the maximal carotid wall intima-media thickness of the ICA (ICA-maxIMT) and plaque in 83 patients with OSAS. The ICA-maxIMT values were positively correlated with the apnea hypopnea index (AHI) (ρ = 0.294, P = 0.007), arousal index (ρ = 0.289, P = 0.008), oxygen desaturation index (ρ = 0.298, P = 0.006), percentage of visually scored total sleep time spent in nocturnal oxygen saturation < 90% (SpO2 < 90%) (ρ= 0.246, P = 0.025), and the percentage of visually scored total sleep time spent in non-REM sleep stage 1 (ρ = 0.326, P = 0.003) and were negatively correlated with the percentage of visually scored total sleep time spent in non-REM sleep stages 2 and 3. Arousal index, diabetes mellitus, and age were found to be independent predictors of ICA plaque presence (OR 1.052, P = 0.003; OR 8.705, P = 0.026; OR 1.064, P = 0.023, respectively). Several PSG variables that are indicative of sleep fragmentation, sleep disordered breathing, and poor sleep quality correlated with the occurrence of atherosclerosis, but total arousal index was the only independent predictive factor.

Osteopontin, Cardiovascular Risk Factors and Carotid Intima-Media Thickness in Chronic Kidney Disease.

The pleiotropic cytokine osteopontin (OPN) is found to be involved in the pathogenesis of both kidney and cardiovascular disease (CVD). We evaluated the relationship between OPN, other cardiovascular risk factors and carotid intima-media thickness (CIMT) in chronic kidney disease (CKD) (predialysis) patients. This is a 2-year cross-sectional prospective study involving 75 patients with CKD from stage 1 to stage 5 attending the nephrology outpatient department and 25 healthy controls. Routine biochemical parameters were analyzed on clinical chemistry Autoanalyzer Beckman Coulter DXC 600 Synchron, USA. OPN was estimated by ELISA method. Carotid intima-media wall thickness was estimated by Doppler of carotid vessels. Serum OPN and other nontraditional cardiovascular risk factors such as CIMT, lipoprotein (a) Lp(a), fibrinogen, and homocysteine were significantly increased in patients of CKD compared to controls. OPN, Lp(a), fibrinogen, CIMT, parathyroid hormone, and homocysteine progressively increased from early stages of CKD and increased further with progression of the disease, but nitric oxide (NO) level progressively decreased with progression of CKD. OPN showed a positive correlation with CIMT, Lp(a), fibrinogen, and homocysteine and negative correlation with estimated glomerular filtration rate and NO. There was a close direct association between circulating levels of OPN and the presence of atherosclerotic plaques in carotid arteries of patients with CKD. Osteopontin and nontraditional CVD risk factors are altered in early stages of CKD and might predict adverse outcomes in these patients.

Gamma prime (γ') fibrinogen and carotid intima-media thickness: the Atherosclerosis Risk in Communities study.

: We assessed if γ' fibrinogen, an isoform of fibrinogen, is independently associated with subclinical atherosclerosis beyond total fibrinogen in black and white men and women participating in the Atherosclerosis Risk in Communities study. Fasting γ' fibrinogen was measured in 6847 Atherosclerosis Risk in Communities participants, ages 51-70 years, in 1993-1995. Carotid intima-media far wall thickness (CIMT) was measured by B-mode ultrasonography at the common, internal and bifurcation carotids. The association of γ' fibrinogen tertiles with overall and segment-specific mean CIMT was assessed with linear regression, controlling for fibrinogen as well as cardiovascular risk factors, including high-sensitivity C-reactive protein and D-dimer. γ' Fibrinogen values ranged from 8.0 to 80.3 mg/dl and were positively related to age, female sex, black race, smoking, BMI, lipids and SBP. Crude γ' fibrinogen was directly associated with all CIMT measures except for the internal carotid, but explained less than 1% of the variance in the associations. Adjustment for total fibrinogen eliminated these associations, and total fibrinogen remained an independent predictor of CIMT without explaining additional variance. Adjustment for potential confounding variables did not alter the observed associations, which did not differ by race or sex. In these cross-sectional data, γ' fibrinogen was not independently associated with CIMT when controlling for total fibrinogen. γ' Fibrinogen and total fibrinogen together explained a very small proportion of the variance in CIMT, regardless of the carotid site. If γ' fibrinogen adds to total fibrinogen's ability to predict subclinical atherosclerosis, it may be in younger populations.

The effects on carotid artery intima-media wall thickness and development of atherosclerosis in children on anti-epileptic drug monotherapy

Background: Children with seizure disorder and requiring long-term anti-epileptic drugs are predisposed for development of atherosclerosis. We monitored the carotid artery intima wall thickness of the children on Anti-epileptic drug monotherapy along with their lipid profile for a period of one year.Methods: Children under 18 years, who were newly diagnosed with epilepsy or were already on anti-epileptic drug monotherapy were included in the study period of one year. They were then prospectively followed-up at three months and again between the sixth and twelfth month’s period. A high-resolution B-mode ultrasound using a 5-7 MHz linear transducer was employed for measuring the thickness of the carotid intima-media thickness (cIMT). The biochemical parameters including fasting lipid profile, body mass index and dietary habits were also taken.Results: A total of 130 children were included in the study. The values of cIMT observed were 0.38 mm (0.1 mm) and 0.41 mm (0.1mm) in the new (control) and old cases respectively. The values of cIMT were significantly increased in patients receiving Carbamazepine (CBZ) and Phenytoin after 3 months of therapy and with increase in age and duration of intake of anti-epileptic drugs. There were no gender differences in the value of cIMT.Conclusions: The values of serum cholesterol, LDL and HDL were significantly increased in children on CBZ and valproic acid. There was no difference in the lipid profiles of children on Phenytoin and Phenobarbitone. However, the atherogenic indices of the children taking any of the four anti-epileptic drugs were normal.
