Cardiovascular risk factors in HIV infected individuals: Comparison with general adult control population in Greece.

BackgroundAlthough combined antiretroviral therapy has substantially improved the prognosis of people living with HIV (PLHIV), mortality remains higher compared to the general population, mainly due to higher prevalence of non-HIV-related comorbidities, including cardiovascular diseases (CVD). We assessed the prevalence of CVD risk and its contributing factors in adult PLHIV versus general population controls in Greece.SettingsCross-sectional comparison of PLHIV (Athens-Multicenter-AIDS-Cohort-Study; AMACS) versus general population controls (National health examination survey; EMENO).MethodsAll HIV-infected adults with ≥1 measurement of interest (blood pressure, lipids, glucose, weight, height) between 2012–2014 and all EMENO participants (2014–2016) were included. Ten-year total CVD risk was estimated using the Framingham (FRS) or the Systematic Coronary Risk Evaluation (SCORE) equations.Results5839 PLHIV (median age:41.6 years, 85.4% males) and 4820 controls (median age:48 years, 48.4% males) were included. Adjusting for age, sex and origin, PLHIV were more likely to be current smokers (adjusted OR:1.53 [95% CI:1.35–1.74]) and dyslipidemic (aOR:1.18; [1.04–1.34]), less likely to be obese (aOR:0.44 [0.38–0.52], with no differences in hypertension, diabetes or high (≥20%) FRS but with greater odds of high (≥5%) SCORE (aOR:1.55 [1.05–2.30]). Further adjustment for educational level, anti-HCV positivity and BMI showed higher prevalence of hypertension in PLHIV.ConclusionsDespite the relative absence of obesity, PLHIV have higher prevalence of traditional CVD risk factors and higher risk of fatal CVD compared to general population. Regular screening and early management of CVD risk factors in PLHIV should be of high priority for CVD prevention.

Common Variants in IL-20 Gene are Associated with Subclinical Atherosclerosis, Cardiovascular Risk Factors and IL-20 Levels in the Cohort of the Genetics of Atherosclerotic Disease (GEA) Mexican Study.

Inflammation has been involved in the development of atherosclerosis, type 2 diabetes mellitus, insulin resistance, and obesity. Interleukin 20 is a pro-inflammatory cytokine encoded by a polymorphic gene located in chromosome 1. The aim of the study was to evaluate the association of two IL-20 polymorphisms (rs1400986 and rs1518108) with subclinical atherosclerosis (SA), cardiovascular risk factors and IL-20 levels in a cohort of Mexican individuals. The polymorphisms were determined in 274 individuals with SA and 672 controls. Under different models, rs1400986 (OR = 0.51, Pcodominant1 = 0.0001; OR = 0.36, Pcodominant2 = 0.014; OR = 0.49, Pdominant = 0.0001 and OR = 0.55, Padditive = 0.0001) and rs1518108 (OR = 0.62, Pcodominant2 = 0.048 and OR = 0.79, Padditive = 0.048) were associated with a lower risk of SA. These polymorphisms were associated with cardiovascular risk factors in individuals with SA and controls. Controls with the rs1400986 TT genotype presented high levels of IL-20 (p = 0.031). In individuals with the rs1400986 CC genotype, we observed a negative correlation between IL-20 levels and total abdominal tissue (TAT), visceral abdominal tissue (VAT) and subcutaneous abdominal tissue (SAT). Our results indicate that the IL-20 rs1400986 and rs1518108 polymorphisms were associated with decreased risk of developing SA and with some cardiovascular risk factors in individuals with SA and healthy controls. Negative correlation between BMI and VAT/SAT ratio in individuals with rs1400986 CC genotype and among IL-20 levels and TAT, VAT and SAT was observed.

Excess heart age in adult outpatients in routine HIV care.

Cardiovascular disease (CVD) is a common cause of morbidity and mortality among persons living with HIV (PLWH). We used individual cardiovascular risk factor profiles to estimate heart age for PLWH in medical care in the United States. Cross-sectional analyses of HIV Outpatient Study (HOPS) data METHODS:: Included in this analysis were participants aged 30-74 years, without prior CVD, with at least two HOPS clinic visits during 2010-2017, at least 1-year of follow-up, and available covariate data. We calculated age and race/ethnicity-adjusted heart age and excess heart age (chronological age - heart age), using a Framingham risk score-based model. We analyzed data from 2467 men and 619 women (mean chronologic age 49.3 and 49.1 years, and 23.6% and 54.6% Non-Hispanic/Latino black, respectively). Adjusted excess heart age was 11.5 years (95% confidence interval, 11.1-12.0) among men and 13.1 years (12.0-14.1) among women. Excess heart age was seen among all age groups beginning with persons aged 30-39 years [men, 7.8 (6.9-8.8); women, 7.7 (4.9-10.4)], with the highest excess heart age among participants aged 50-59 years [men, 13.7 years (13.0-14.4); women, 16.4 years (14.8-18.0)]. More than 50% of participants had an excess heart age of at least 10 years. Excess heart age is common among PLWH, begins in early adulthood, and impacts both women and men. Among PLWH, CVD risk factors should be addressed early and proactively. Routine use of the heart age calculator may help optimize CVD risk stratification and facilitate interventions for aging PLWH.

【論文摘要】The Association of Long-term PM2.5 Absorbance Exposure with Carotid-intima-media Thickness in Young Taiwanese

Background/Synopsis: The contribution of long-term air pollution exposures to subclinical atherosclerosis in young age has not been fully studied. Objectives/Purpose: This study is to evaluate to assess the associations of carotid intima-media thickness (CIMT) values in adolescents or young adults with one-year exposures to different sizes of particulate matter (PM) and traffic-related exhausts. Methods/Results: We recruited 789 school age subjects who resided in Taipei City and participated in the YOung TAiwanese (YOTA) Cohort between 1992 and 2000. Of all study subjects, 303 subjects were elevated blood pressures (EBP) and 486 subjects had normal BP (NBP) in the childhood. The CIMT values at different segments were measured at the age of 12-30 in the follow-up health examination from 2006 to 2008. Land-use regression models were used to estimate participants' one-year exposures to particulate matter (PM) of different sizes and traffic-related exhausts, including PM2.5 absorbance, nitrogen oxides, and nitrogen dioxides. Generalized linear regression was applied to assess the associations of CIMT values in adolescents or young adults with one-year exposures to six air pollutants. Our findings indicate one-year exposure to PM2.5 absorbance is associated with increased mean and maximum CIMT at different carotid segments. Specifically, exposure to PM2.5 absorbance among subjects who exhibited elevated childhood blood pressure is associated with an increases in mean CMIT at common carotid artery by 3.94% (95%CI: 0.24, 7.64), carotid bulb by 7.77% (95%CI: 2.95, 12.95), and internal carotid artery by 4.75% (95%CI: 0.67, 8.84). Similar increases in the maximum CIMT values were evident at the aforementioned sites. Moreover, older age, gender and health status (overweight, elevated blood pressure, hyperglycemia and hypercholesterolemia), coupled with high level exposure to PM2.5 absorbance (≥2.18 10-5 m-1; 75th percentile), are particularly at risk for developing increased CIMT. Conclusion: Long-term exposure to PM2.5 absorbance is positively associated with subclinical atherosclerosis in adolescents or young adults. The atherosclerosis developed since early childhood depending on individual cardiovascular risk factors including overweight, hypertension, hyperglycemia, or hypercholesterolemia, and can be modified by PM2.5 absorbance concentration.

Screening for Cardiovascular Disease Risk Factors in a Physical Therapist Wound Care Practice: A Retrospective, Observational Study

This study assessed the prevalence of cardiovascular risk factors in individuals seeking physical therapist services for an integumentary disorder in an outpatient wound care center. Using a retrospective, observational study design, records from patients who were screened upon initial evaluation by a physical therapist for cardiovascular risk according to the American College of Sports Medicine (ACSM) guidelines were abstracted. The screening process entailed assessment of current signs and symptoms of cardiovascular, pulmonary, or metabolic disease; an individual or family history of cardiovascular disease; whether the patient was considered obese; and whether the patient was a current smoker, had a sedentary lifestyle, dyslipidemia, elevated glucose, or blood pressure ⟩140/90 mm Hg. Patient demographics and wound history also were summarized and described, including wound type and duration and pain associated with the wound. Wounds then were classified by the physical therapist as either venous leg ulcers or nonvenous leg ulcers based upon the referring physician's diagnosis. Descriptive statistics and frequency distributions were calculated to assess the prevalence of individual cardiovascular risk factors, total number of cardiovascular risk factors, cardiovascular risk stratification, and patient disposition. Frequencies of individual cardiovascular risk factors, total number of cardiovascular risk factors, and cardiovascular risk stratification also were assessed between patients with venous leg ulcers and nonvenous leg ulcers using chi-square tests for categorical data and t tests for continuous data. The alpha level was set at P <.05. Among the 70 study participants (41 male, 29 female; mean age 63.5 ± 15.1 years), 38 were treated for venous leg ulcers and 32 were treated for nonvenous leg ulcers. Overall, 38 patients (54%) had a history of cardiovascular disease and 29 (41%) had current signs and symptoms of cardiovascular disease. Patients with nonvenous leg ulcers had a significantly higher frequency of having a family history of cardiovascular disease than patients with venous leg ulcers (28% vs. 8%; P = .03). According to the ACSM guidelines, 5 patients (7%) were considered low risk, 22 (31%) were moderate risk, and 43 (62%) were at high risk for experiencing a future cardiovascular event. Cardiovascular risk did not vary significantly according to wound type. The patient risk-stratification profile in this study strongly suggested physical therapists should screen for cardiovascular risk factors before prescribing aerobic exercise or other physical activity for all patients being seen for an integumentary disorder in an outpatient wound care practice.

Association Of Il-37 Rs2708965 Polymorphism With Cardiovascular Risk Factors In Individuals With Coronary Artery Disease, Subclinical Atherosclerosis And Healthy Controls. The Gea Mexican Study.

Background and Aims: The Interleukin 37 (IL-37) is an anti-inflammatory cytokine with similar functions to the interleukin 10. IL-37 has been detected in carotid and coronary atherosclerotic plaques suggesting its participation in the development coronary artery disease (CAD). Thus, the aim of the present study was to evaluate the association of the IL-37 rs2708965 polymorphism with the presence of CAD, subclinical atherosclerosis (SA) and cardiovascular risk factors.

Inflammation and Vascular Ageing: From Telomeres to Novel Emerging Mechanisms.

Cardiovascular disease (CVD) remains the leading cause of morbility and mortality worldwide. The identification of common cardiovascular risk factors has led to the development of effective treatments that enabled a significant reduction of the global cardiovascular disease burden. However, a significant proportion of cardiovascular risk remains unexplained by these risk factors leaving many individuals at risk of cardiovascular events despite good control of the risk factors. Recent randomized clinical trials and Mendelian randomization studies have suggested that inflammation explains a significant proportion of the residual cardiovascular risk in subjects with good control of risk factors. An accelerated process of vascular ageing is increasingly recognized as a potential mechanism by which inflammation might increase the risk of CVD. In turn, cellular ageing represents an important source of inflammation within the vascular wall, potentially creating a vicious cycle that might promote progression of atherosclerosis, independently from the individual cardiovascular risk factor burden. In this review, we summarise current evidence suggesting a role for biological ageing in CVD and how inflammation might act as a key mediator of this association.

Association of Hair Cortisol Concentration with Prevalence of Major Cardiovascular Risk Factors and Allostatic Load.

BackgroundThe high prevalence of cardiovascular diseases cannot be explained completely by conventional risk factors such as older age, smoking, diabetes mellitus, hypertension, obesity, and dyslipidemia. Results of recent studies indicate that chronic stress may be an independent risk factor for cardiovascular morbidity and mortality. Thus, the aim of our study was to investigate the associations between the hair cortisol concentration (HCC), which is considered as a potential biomarker of long-term psychosocial stress, and traditional cardiovascular risk factors, including smoking, dyslipidemia, hypertension, and obesity.Material/MethodsFasting blood samples and anthropometric and lifestyle data were collected from 163 apparently healthy men. HCC was determined using high-performance liquid chromatography. Allostatic load (AL) index, defined as an integrated score of multiple interacting systems involved in the adaptation to adverse physical or psychosocial situations, was also calculated.ResultsWe found that many prevalent cardiovascular risk factors, including hypertension, smoking, higher than recommended waist circumference (WC), and low-density lipoprotein cholesterol (LDL-C) median values, are associated with higher HCC. Hair cortisol level was also positively associated with the manifestation of individual cardiovascular risk factors such as higher-than-recommended total cholesterol, LDL-C, non-high-density lipoprotein cholesterol, body mass index, and WC median values. Moreover, a significant positive relationship between HCC and AL index was observed.ConclusionsThe results of this study suggest that increased prevalence of traditional cardiovascular risk factors is associated with higher HCC. Also, both HCC and AL index might be appropriate markers for the evaluation of chronic stress level.

Adherence to a priori dietary indexes and baseline prevalence of cardiovascular risk factors in the PREDIMED-Plus randomised trial.

Cardiovascular disease remains the global leading cause of death. We evaluated at baseline the association between the adherence to eight a priori high-quality dietary scores and the prevalence of individual and clustered cardiovascular risk factors (CVRF) in the PREDIMED-Plus cohort. All PREDIMED-Plus participants (6874 men and women aged 55-75years, with overweight/obesity and metabolic syndrome) were assessed. The prevalence of 4 CVRF (hypertension, obesity, diabetes, and dyslipidaemia), using standard diagnoses criteria, were considered as outcomes. The adherence to eight a priori-defined dietary indexes was calculated. Multivariable models were fitted to estimate differences in mean values of factors and prevalence ratios for individual and clustered CVRF. Highest conformity to any dietary pattern did not show inverse associations with hypertension. The modified Mediterranean Diet Score (PR = 0.95; 95% CI 0.90-0.99), Mediterranean Diet Adherence Score (MEDAS) (PR = 0.94; 95% CI 0.89-0.98), the pro-vegetarian dietary pattern (PR = 0.95; 95% CI 0.90-0.99) and the Alternate Healthy Eating Index 2010 (PR = 0.92; 95% CI 0.87-0.96) were inversely associated with prevalence of obesity. We identified significant inverse trend among participants who better adhered to the MEDAS and the Prime Diet Quality Score (PDQS)in the mean number of CVRF across categories of adherence. Better adherence to several high-quality dietary indexes was associated with better blood lipid profiles and anthropometric measures. Highest adherence to dietary quality indexes, especially Mediterranean-style and PDQS scores, showed marginal associations with lower prevalence of individual and clustered CVRF among elderly adults with metabolic syndrome at high risk of cardiovascular disease.

Epicardial fat, cardiovascular risk factors and calcifications in patients with chronic kidney disease.

BackgroundEpicardial adipose tissue (EAT) exerts cardiopathogenic effects, but the independent association between EAT and cardiovascular (CV) calcification in patients with chronic kidney disease (CKD) remains controversial. We therefore assessed the association between EAT, CV risk factors and CV calcifications.Methods257 patients with CKD Stage 3 and/or overt proteinuria underwent quantification of EAT, coronary artery calcification and aortic valve calcification by computed tomography. Framingham and American College of Cardiology and American Heart Association (ACC-AHA) 10-year CV event risk scores were calculated for each patient.ResultsUsing multivariable regression analysis, higher EAT was significantly associated with the majority of investigated risk factors {higher age: odds ratio [OR] 1.05/year [95% confidence interval (CI) 1.02–1.08]; male sex: OR 4.03 [95% CI 2.22–7.31]; higher BMI: OR 1.28/kg/m2 [95% CI 1.20–1.37]; former smoking: OR 1.84 [95% CI 1.07–3.17]; lower high-density lipoprotein cholesterol: OR 0.98/mg/dL [95% CI 0.96–1.00] and lower estimated glomerular filtration rate: OR 0.98/mL/min/1.73 m2 [95% CI 0.97–0.99]; all P < 0.05} and was not associated with diabetes mellitus, hypertensive nephropathy, total cholesterol and albuminuria. EAT was positively associated with higher ACC-AHA and Framingham risk scores. EAT correlated with coronary artery calcification and aortic valve calcification [Spearman ρ = 0.388 (95% CI 0.287–0.532) and rrb = 0.409 (95% CI 0.310–0.556), respectively], but these correlations were dependent on CV risk factors.ConclusionsThe increase of EAT can be explained by individual CV risk factors and kidney function and correlates with 10-year risk for CV event scores, suggesting that EAT is a modifiable risk factor in patients with CKD. Although EAT correlates with CV calcifications, these relations depend on CV risk factors.

Carotid artery volumetric measures associate with clinical ten-year cardiovascular (CV) risk scores and individual traditional CV risk factors in rheumatoid arthritis; a carotid-MRI feasibility study

BackgroundCommon carotid artery intima-media thickness (CIMT), as measured by ultrasound, has utility in stratification of the accelerated cardiovascular risk seen in rheumatoid arthritis (RA); however, the technique has limitations. Carotid magnetic resonance imaging (MRI) is emerging as a useful research tool in the general population, but has yet to be applied in RA populations. Our objectives were to describe the utility of carotid artery MRI (carotid-MRI) in patients with RA in comparison to healthy controls and to describe the association with RA disease phenotype.MethodsSixty-four patients with RA and no history of cardiovascular (CV) disease/diabetes mellitus were assessed for RA and CV profile, including homeostasis model assessment-estimated insulin resistance (HOMA-IR) and N-terminal pro-brain natriuretic peptide (NT-proBNP). All underwent carotid-MRI (3 T), and were compared to 24 healthy controls. Univariable analysis (UVA) and multivariable linear regression models (MVA) were used to determine associations between disease phenotype and carotid-MRI measures.ResultsThere were no significant differences in carotid arterial wall measurements between patients with RA and controls. Wall and luminal volume correlated with 10-year CV risk scores (adjusted as per 2017 European League Against Rheumatism (EULAR) guidance); rho = 0.33 (p = 0.012) and rho = 0.35 (p = 0.008), respectively, for Joint British Societies-2 risk score. In UVA, carotid-MRI volumetric measures predominantly were associated with traditional CV risk factors including age, ever-smoking and HOMA-IR (p < 0.05). Lower body mass index was associated with wall maximum thickness (r = − 0.25 p = 0.026). In MVA, age was independently associated with wall volume (B 1.13 (95% CI 0.32, 1.93), p = 0.007) and luminal volume (B 3.69 (95% CI 0.55, 6.83, p = 0.022), and RA disease duration was associated with luminal volume (B 3.88 (95% CI 0.80, 6.97), p = 0.015).ConclusionsThis study demonstrates the utility of carotid-MRI in RA, reporting an association between three-dimensional measures in particular and CV risk scores, individual traditional CV risk factors and RA disease duration. Carotid-MRI in RA is a promising research tool in the investigation of CVD.

Neck circumference is associated with non-traditional cardiovascular risk factors in individuals at low-to-moderate cardiovascular risk: cross-sectional analysis of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil)

BackgroundNeck circumference (NC) is associated with traditional cardiovascular risk factors (CVRF), but its usefulness to identify earlier atherogenic risk has been scarcely examined. Associations of NC with non-traditional CVRF were investigated in participants at low-to-moderate risk from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil).Methods807 individuals (35–54 years) without obesity, diabetes or cardiovascular disease was stratified into quartiles of NC (cut-off for men: 36.5; 37.9 and 39.5 cm; women: 31.4; 32.5 and 34 cm) and traditional and non-traditional risk factors (lipoprotein subfractions by Vertical Auto Profile, adiponectin, leptin, E-selectin) were compared across groups. In linear regression models, associations of NC with non-traditional risk factors were tested for the entire sample and for low-risk group (≤ 2 CVRF).ResultsIn both sexes, BMI, waist circumference, systolic and diastolic blood pressure, fasting and 2-h plasma glucose, HOMA-IR, triglycerides, leptin, E-selectin, small dense LDL-cholesterol, IDL-cholesterol, VLDL3-cholesterol and TG/HDL ratio increased significantly, while HDL2-cholesterol and HDL3-cholesterol decreased across NC quartiles. In linear regression models, a direct association [β(95% CI)] of NC with leptin [(0.155 (0.068–0.242); 0.147 (0.075–0.220)], E-selectin [(0.105 (0.032–0.177); 0.073 (0.006 to 0.140)] and small-dense LDL [(1.866 (0.641–3.091); 2.372 (1.391–3.353)] and an inverse association with HDL2-cholesterol [(− 0.519 (− 0.773 to − 0.266); − 0.815 (− 1.115 to 0.515)] adjusted for age were detected for men and women, respectively.ConclusionOur findings indicate that measurement of NC may be useful for an earlier identification of unfavorable atherogenic metabolic profile in middle-aged individuals at lower cardiovascular risk level.

Cardiovascular and Metabolic Outcomes in Congenital Adrenal Hyperplasia: A Systematic Review and Meta-Analysis.

Individuals with congenital adrenal hyperplasia (CAH) require glucocorticoid therapy to replace cortisol and to control androgen excess. We sought to evaluate the effects of glucocorticoid therapy on cardiovascular and metabolic outcomes in individuals with CAH. We searched bibliographical databases through January 2016 for studies evaluating cardiovascular risk factors in individuals with CAH treated with glucocorticoids compared with controls without CAH. We used a random-effects model to synthesize quantitative data. We included 20 observational studies (14 longitudinal, six cross-sectional) with a moderate to high risk of bias. The average dose of glucocorticoids (in hydrocortisone equivalents) was 9 to 26.5 mg/m2/d. In the meta-analysis (416 patients), compared with controls without CAH, individuals with CAH had increased systolic blood pressure [weighted mean difference (WMD), 4.44 mm Hg; 95% CI, 3.26 to 5.63 mm Hg], diastolic blood pressure (WMD, 2.35 mm Hg; 95% CI, 0.49 to 4.20 mm Hg), homeostatic model assessment of insulin resistance (WMD, 0.49; 95% CI, 0.02 to 0.96), and carotid intima thickness (WMD, 0.08 mm; 95% CI, 0.01 to 0.15 mm). No statistically significant differences were noted in fasting blood glucose, insulin level, glucose, or insulin level after 2-hour glucose load or serum lipids. Data on cardiac events were sparse, and most of the literature focused on surrogate outcomes. Individuals with CAH demonstrate a high prevalence of cardiovascular and metabolic risk factors. The current evidence relies on surrogate outcomes. Long-term prospective studies are warranted to assess strategies for reducing cardiovascular risk in individuals with CAH.

Cardiovascular events in patients under age fifty with early findings of elevated lipid and glucose levels - The AMORIS study.

BackgroundThe long-term trajectories of lipid and glucose levels in subjects who experience a major cardiovascular (CV) event at a young age has not been well studied. Our objective was to investigate lipid, lipoprotein, apolipoprotein (apo), and glucose levels in individuals experiencing a CV event before 50 years of age.Methods and findingsA first CV event [non-fatal myocardial infarction (MI), coronary revascularisation, or CV related death] before age 50 was recorded in 2,939 (cumulative incidence 1.2% in males and 0.3% in females) of 361,353 individuals included in the prospective Swedish AMORIS (Apolipoprotein-related MOrtality RISk) study with health examinations 1985–1996 and follow-up through 2011. In a nested case-control analysis, cases with a CV event were matched to randomly selected controls. Population risk factor trajectories were calculated up to 20 years prior to an event. Total cholesterol (TC), triglyceride (TG), and glucose levels were higher in cases than in controls as early as 20 years prior to the event with differences increasing over time. Low density lipoprotein, apoB, and the apoB/apoA-1 ratio were higher and increased over time, while HDL and apoA-1 were lower in cases compared to controls. The odds ratio was 2.5 (95% confidence interval 1.6–3.7) for TC ≥5 mmol/L and TG ≥1.7 mmol/L in cases versus controls. The adjusted population-attributable fractions including lipids, glucose, diabetes, smoking, hypertension, and obesity indicated that about 50% of CV events before age 50 may be associated with elevated lipid and glucose levels.ConclusionsElevated TC, TG, LDL, apoB, and glucose levels and high apoB/apo A-1 ratio documented two decades before a CV event in subjects younger than 50 years may account for about half of CV events before age 50, which calls for early recognition and possibly treatment of modifiable CV risk factors in young individuals.

Ethnic disparities in treatment rates for hypertension and dyslipidemia: an analysis by different treatment indications: the Healthy Life in an Urban Setting study.

Studies have reported ethnic disparities in treatment rates for cardiovascular risk factors. These studies are generally based on treatment indications defined by individual cardiovascular risk factors (ICRF). However, according to most European guidelines, preventive treatment for these risk factors is recommended only among those with sufficient overall cardiovascular risk (OCR). To determine ethnic disparities in treatment rates for hypertension and dyslipidemia among those with an indication for treatment based on ICRF and OCR. Using data of the HELIUS study, we determined the occurrence of cardiovascular risk factors and treatment rates among 11 357 participants from six ethnic backgrounds living in Amsterdam. Via logistic regression analyses, we determined ethnic differences in blood pressure (BP)-lowering or lipid-lowering treatment rates among those needing treatment based on ICRF (BP >140 mmHg and LDL >2.5 mmol/l, respectively) and on OCR (estimated overall 10-year cardiovascular disease risk according to SCORE). Relative to the Dutch, ethnic minority men showed higher treatment rates for hypertension and dyslipidemia, regardless of whether OCR of ICRF recommendations for treatment were used. Ethnic minority women showed similar treatment rates relative to the Dutch based on OCR, but higher treatment rates based on ICRF recommendations (e.g. odds ratios for antihypertensive treatment ranged from 0.93 to 1.75 and from 1.26 to 1.93, respectively). Treatment rates for hypertension and dyslipidemia are not lower among ethnic minority groups relative to the Dutch. In some cases, they are even higher, but these differences may be overestimated whenever using ICRF as treatment indication.

CARDIOVASCULAR RISK FACTORS AND ARTERIAL STIFFNESS IN MEN AGED 41–43 YEARS

Objective: To study the relationship of individual cardiovascular risk factors with arterial stiffness and subclinical atherosclerosis. Design and method: The study is the part of a 32-year prospective cohort monitoring, beginning with childhood (11–12 years). The present cohort included 303 male subjects aged 41–43 years. Arterial stiffness (AS) was measured by aortic pulse wave velocity (PWV) and arterial wave reflections (augmentation index, Alx) with the use of SphygmoCor (AtCor Medical). Intima-media thickness (IMT) and subclinical atherosclerosis were estimateded by ultrasonography methods both in left and right carotid arteries. Results: Hypertension (H) was detected in 37,9%. PWV was significantly higher in the group with H. The risk of H development depended on hypertension presence in mother and did not depend on the presence of H in father. H was associated with the development of obesity, especially of the abdominal type and increased level of triglycerides. PWV was positively correlated with systolic (r = 0.248, p < 0.001) and diastolic blood pressure (BP) (r = 0.220, p < 0.001) measured on the brachial artery and with heart rate (r = 0.164, p < 0.01). A statistically significant positive correlation of the central aortic pressure (r = 0.326, p < 0.001) and central pulse pressure (r = 0.225, p < 0.001) with PWV was noted. When comparing arterial stiffness (AS) and duplex scan a correlation of mean IMT with the Alx (r = 0.134, p < 0.05) and augmentation pressure (r = 0.127, p < 0.05) was obtained, but no correlation between IMT and PWV was found. Correlation of AS with total cholesterol and glucose was also shown. Conclusions: The AS is closely related with H and develops already in the early stages, in a fairly young age. The AS in men group was not associated with the presence of dyslipidemia and diabetes melitus. The interrelation of arterial stiffness and the degree of early atherosclerotic vascular lesions is ambiguous.

EX-MET study: exercise in prevention on of metabolic syndrome \u2013 a randomized multicenter trial: rational and design

BackgroundMetabolic syndrome substantially increases risk of cardiovascular events. It is therefore imperative to develop or optimize ways to prevent or attenuate this condition. Exercise training has been long recognized as a corner-stone therapy for reducing individual cardiovascular risk factors constituting the metabolic syndrome. However, the optimal exercise dose and its feasibility in a real world setting has yet to be established.The primary objective of this randomized trial is to investigate the effects of different volumes of aerobic interval training (AIT) compared to the current exercise guideline of moderate-intensity continuous training (MICT) on the composite number of cardiovascular disease risk factors constituting the metabolic syndrome after a 16 week, 1-year, and 3-year follow-up.MethodsThis is a randomized international multi-center trial including men and women aged ≥30 years diagnosed with the metabolic syndrome according to the International Diabetes Federation criteria. Recruitment began in August 2012 and concluded in December 2016. This trial consists of supervised and unsupervised phases to evaluate the efficacy and feasibility of different exercise doses on the metabolic syndrome in a real world setting. This study aims to include and randomize 465 participants to 3 years of one of the following training groups: i) 3 times/week of 4 × 4 min AIT at 85–95% peak heart rate (HRpeak); ii) 3 times/week of 1 × 4 min AIT at 85–95% HRpeak; or iii) 5–7 times/week of ≥30 min MICT at 60–70% HRpeak. Clinical examinations, physical tests and questionnaires are administered to all participants during all testing time points (baseline, 16 weeks and after 1-, and 3-years).DiscussionThis multi-center international trial indeed aims to ease the burden in healthcare/economic cost arising from treating end-stage CVD related conditions such as stroke and myocardial infarction, that could eventually emerge from the metabolic syndrome condition.Trial registrationClinical registration number: NCT01676870, ClinicalTrials.gov (August 31, 2012).

Individual fatty acids in erythrocyte membranes are associated with several features of the metabolic syndrome in obese children.

Obesity leads to the clustering of cardiovascular (CV) risk factors and the metabolic syndrome (MetS) also in children and is often accompanied by non-alcoholic fatty liver disease. Quality of dietary fat, beyond the quantity, can influence CV risk profile and, in particular, omega-3 fatty acids (FA) have been proposed as beneficial in this setting. The aim of the study was to evaluate the associations of individual CV risk factors, characterizing the MetS, with erythrocyte membrane FA, markers of average intake, in a group of 70 overweight/obese children. We conducted an observational study. Erythrocyte membrane FA were measured by gas chromatography. Spearman correlation coefficients (rS) were calculated to evaluate associations between FA and features of the MetS. Mean content of Omega-3 FA was low (Omega-3 Index = 4.7 ± 0.8%). Not omega-3 FA but some omega-6 FA, especially arachidonic acid (AA), were inversely associated with several features of the MetS: AA resulted inversely correlated with waist circumference (rS = - 0.352), triglycerides (rS = - 0.379), fasting insulin (rS = - 0.337) and 24-h SBP (rS = - 0.313). Total amount of saturated FA (SFA) and specifically palmitic acid, correlated positively with waist circumference (rS = 0.354), triglycerides (rS = 0.400) and fasting insulin (rS = 0.287). Fatty Liver Index (FLI), a predictive score of steatosis based on GGT, triglycerides and anthropometric indexes, was positively correlated to palmitic acid (rS = 0.515) and inversely to AA (rS = - 0.472). Our data suggest that omega-6 FA, and especially AA, could be protective toward CV risk factors featuring the MetS and also to indexes of hepatic steatosis in obese children, whereas SFA seems to exert opposite effects.

ASSOCIATIONS BETWEEN CONVENTIONAL CARDIOVASCULAR RISK FACTORS AND RISK OF PERIOPERATIVE ACUTE MYOCARDIAL INFARCTION AFTER NON-CARDIAC SURGERY

Adverse cardiovascular (CV) events are a leading cause of morbidity and mortality after non-cardiac surgery. Prior studies report associations between individual CV risk factors (RF) and the risk of acute myocardial infarction (AMI), but the combined effects of these RFs are largely unknown. Data
