Abdominal obesity and coronary heart disease in Thai men

Objective: To determine the association of four simple anthropometric indices with coronary heart disease (CHD) in Thai men, and to determine the optimal cut‐off points for each index in the prediction of CHD. Research Methods and Procedures: This is a cohort study with 17 years of follow‐up. A total of 2536 male employees from the Electricity Generating Authority of Thailand 35 to 59 years of age at baseline were included in the study. Height, weight, waist circumference, and hip circumference were measured to generate BMI, waist circumference (WC), waist‐to‐hip ratio (WHR), and waist‐to‐height ratio (WHtR). Cox regression models were used to estimate hazard ratios by thirds of each index. Receiver operating characteristic curves were used to assess discrimination of CHD. Results: WHtR was most strongly associated with CHD events in Thai men. The age‐adjusted hazard ratio for those in the highest, compared with the lowest, third was 2.89 (1.37, 6.11). Although WHtR had the largest area under the receiver operating characteristic curve (AUC) with the optimal cut‐off estimated to be 0.51 (sensitivity, 55%; specificity, 61%), no statistically significant difference (p > 0.10) was found between the AUC for WHtR and that for the other three indices. Conclusion: WHtR is, marginally, the best of the four indices considered to predict CHD events in Thai men.     

Gene-environment interactions of CETP gene variation in a high cardiovascular risk Mediterranean population

Genome-wide association studies show that cholesteryl ester transfer protein (CETP) single nucleotide polymorphisms (SNPs) are more strongly associated with HDL cholesterol (HDL-C) concentrations than any other loci across the genome. However, gene-environment interactions for clinical applications are still largely unknown. We studied gene-environment interactions between CETP SNPs and dietary fat intake, adherence to the Mediterranean diet, alcohol consumption, smoking, obesity, and diabetes on HDL-C in 4,210 high cardiovascular risk subjects from a Mediterranean population. We focused on the −4,502C>T and the TaqIB SNPs in partial linkage disequilibrium (D''= 0.88; P < 0.001). They were independently associated with higher HDL-C (P < 0.001); this clinically relevant association was greater when their diplotype was considered (14% higher in TT/B2B2 vs. CC/B1B1). No gene-gene interaction was observed. We also analyzed the association of these SNPs with blood pressure, and no clinically relevant associations were detected. No statistically significant interactions of these SNPs with obesity, diabetes, and smoking in determining HDL-C concentrations were found. Likewise, alcohol, dietary fat, and adherence to the Mediterranean diet did not statistically interact with the CETP variants (independently or as diplotype) in determining HDL-C. In conclusion, the strong association of the CETP SNPs and HDL-C was not statistically modified by diet or by the other environmental factors.     

Impact of cardiovascular risk factors on oxidative stress and DNA damage in a high risk Mediterranean population

Abstract

The impact of classic cardiovascular risk factors on oxidative stress status in a high-risk cardiovascular Mediterranean population of 527 subjects was estimated. Oxidative stress markers (malondialdehyde, 8-oxo-7′8′-dihydro-2′-deoxyguanosine, oxidized/reduced glutathione ratio) together with the activity of antioxidant enzyme triad (superoxide dismutase, catalase, glutathione peroxidase) were analysed in circulating mononuclear blood cells. Malondialdehyde, oxidized glutathione and the ratio of oxidized to reduced glutathione were significantly higher while catalase and glutathione peroxidase activities were significantly lower in high cardiovascular risk participants than in controls. Statistically significant differences were obtained after additional multivariate control for sex, age, obesity, diabetes, lipids and medications. Among the main cardiovascular risk factors, hypertension was the strongest determinant of oxidative stress in high risk subjects studied at a primary prevention stage.     

Genes, fat intake, and cardiovascular disease risk factors in the Quebec Family Study

Objective: The aim of this study was to assess gene‐diet interaction effects on cardiovascular disease (CVD) risk factors (waist circumference, plasma triacylglycerol, high‐density lipoprotein‐cholesterol and fasting glucose concentrations, and diastolic and systolic blood pressure) in the Quebec Family Study cohort. Design: Sixty‐four polymorphisms from 45 candidate genes were studied in 645 subjects. Dietary fat intake was obtained from a 3‐day weighted food record. Results: We observed 18 significant interactions at a p value ≤ 0.01. Among them, the Pro12Ala polymorphism in peroxisome proliferator‐activated receptor γ, alone or in interaction with fat intake, significantly modulated waist circumference (p = 0.0005 for both effects). Additionally, the apolipoprotein E genotype in interaction with fat intake was significantly associated with diastolic and systolic blood pressure (p = 0.01 and p = 0.001, respectively). The ghrelin Leu72Met polymorphism also interacted with dietary fat in its relation to waist circumference and triacylglycerol concentrations (p = 0.0004 and p = 0.005). Discussion: These results suggest that several alleles at candidate genes interact with dietary fat intake to modulate well‐known CVD risk factors. The identification of gene‐diet interaction effects is likely to provide useful information concerning the etiology of CVD.     

Telomere length and cardiovascular risk factors in a middle-aged population free of overt cardiovascular disease

Evidence assembled over the last decade shows that average telomere length (TL) acts as a biomarker for biological aging and cardiovascular disease (CVD) in particular. Although essential for a more profound understanding of the underlying mechanisms, little reference information is available on TL. We therefore sought to provide baseline TL information and assess the association of prevalent CVD risk factors with TL in subjects free of overt CVD within a small age range. We measured mean telomere restriction fragment length of peripheral blood leukocytes in a large, representative Asklepios study cohort of 2509 community-dwelling, Caucasian female and male volunteers aged approximately 35-55 years and free of overt CVD. We found a manifest age-dependent telomere attrition, at a significantly faster rate in men as compared to women. No significant associations were established with classical CVD risk factors such as cholesterol status and blood pressure, yet shorter TL was associated with increased levels of several inflammation and oxidative stress markers. Importantly, shorter telomere length was associated with an increasingly unhealthy lifestyle, particularly in men. All findings were age and gender adjusted where appropriate. With these cross-sectional results we show that TL of peripheral blood leukocytes primarily reflects the burden of increased oxidative stress and inflammation, whether or not determined by an increasingly unhealthy lifestyle, while the association with classical CVD risk factors is limited. This further clarifies the added value of TL as a biomarker for biological aging and might improve our understanding of how TL is associated with CVD.     

Obesity and the clustering of cardiovascular disease risk factors in 14-year-old children

Although overweight and obesity in childhood are related to risk factors of cardiovascular (CVD), most studies have examined these relationships separately. Internal cut-points were used to examine the relation of overweight (>85th and ≦90th percentile) and obesity (>90th percentile) to risk factor clustering in a sample of 2731 14-year-old children from Lower Silesia, Poland, examined cross-sectionally in 1996–97. All subjects went through anthropometric and blood pressure measurements, and fasting serum levels of lipid, lipoproteins and glucose were estimated. All risk factor (>90th percentile) prevalence increased greatly at higher levels of Body Mass Index (BMI) (kg/m2). Nearly every second obese child had elevated systolic blood pressure and every third child had elevated serum levels of triglycerides. Among overweight boys 24.7% were found to have at least one risk factor, whereas among obese boys every fourth had at least one risk factor. 25% overweight girls and nearly 18% obese girls showed at least one risk factor. Standardized odds ratios for associations between overweight and obesity, and risk factor clustering, indicated that obese boys were 4.8 times more likely to have an elevated level of at least two factors; the probability increasing to 16.1 in the case of three and more factors in comparison to their lean peers. Obese girls showed more then a 7 time higher probability of having three and more risk factors in relation to their lean peers.     

Levels and trends in cardiovascular risk factors and drug treatment in 4837 elderly Dutch myocardial infarction patients between 2002 and 2006

Background

It is important to gain insight into opportunities for secondary prevention of cardiovascular disease. Our aim was to investigate levels and trends in cardiovascular risk factors and drug treatment in Dutch post-myocardial infarction (MI) patients between 2002 and 2006 and to make comparisons with the EUROASPIRE surveys (1999–2007).

Methods

We analysed data from 4837 post-MI patients (aged 69 years, 78% men) from 32 Dutch hospitals, using baseline cross-sectional data from the Alpha Omega Trial.

Results

Between 2002 and 2006, significant declines were found in the prevalence of smoking (23% to 16%, p < 0.001), hypercholesterolaemia (≥5 mmol/l; 54% to 27%, p < 0.0001) and hypertension (≥140/90 mmHg; 58% to 48%, p < 0.001). The prevalence of antithrombotic drugs was high (97%). The prevalence of lipid-modifying drugs and antihypertensives was high, and increased (74% to 90%, p < 0.0001 and 82% to 93%, p < 0.001, respectively). The prevalence of obesity (27%) was high in 2002 and decreased to 24% in 2006, albeit not significantly. Diabetes prevalence was high and increased between 2002 and 2006 (18% to 22%, p = 0.02). In comparison with EUROASPIRE patients, who were on average 8–10 years younger, our study in 2006 included patients with lower levels of obesity, hypertension, hypercholesterolaemia, diabetes and lower use of antiplatelets and β-blockers, but similar levels of lipid-modifying drugs.

Conclusions

This study showed that older Dutch post-MI patients were adequately treated with drugs, and that risk factors reached lower levels than in the younger EUROASPIRE patients. However, there is room for improvement in diet and lifestyle, given the high prevalence of smoking, obesity, and diabetes.

Polymorphisms at newly identified lipid-associated loci are associated with blood lipids and cardiovascular disease in an Asian Malay population

We conducted a cross-sectional study of Malay participants aged 40-80 years (n = 2,932) to examine the associations between polymorphisms at newly identified, lipid-associated loci with blood lipid levels and prevalent cardiovascular disease (CVD) in a Malay population in Asia. A polymorphism adjacent to the TRIB1 locus (rs17321515) was associated with elevated total cholesterol and LDL-cholesterol (LDL-C) after adjustment for age and sex (both P values <0.007) and with increased risk of coronary heart disease and CVD [odds ratio (OR) 1.23, 95% confidence interval (95% CI) 1.03-1.46; and OR 1.2, 95% CI 1.02-1.42, respectively] under an additive model of inheritance. In addition, using recessive models of inheritance, polymorphisms on chromosome 19 adjacent to the CILP2 and PBX4 loci (rs16996148) and on chromosome 1 at the GALNT2 locus (rs4846914) were associated with elevated HDL-C (P = 0.005) and lower LDL-C (P = 0.048), respectively. Although novel, the former is consistent with the association between this polymorphism and lower blood triglycerides observed in the initial studies conducted in populations of European ancestry. Neither showed statistically significant association with CVD. These observations should form the basis of further investigation to identify the causative polymorphisms at this locus, and also to understand the mechanistic roles that this protein may play in lipoprotein metabolism in Asians and other populations.     

Age trends in prevalence of cardiovascular risk factors in Roma minority population of Croatia

The Roma (Gypsy) are the largest European minority population characterized by poverty, social exclusion as well as by numerous life-style and cultural specificities, which all could have an adverse impact on their cardiovascular health. This study assesses the prevalence of cardiovascular diseases (CVD) risk factors in community-based sample of 430 adult Roma, living in rural area of Croatia, by providing the actual and age-adjusted estimates using the European standard population. The most prominent classical CVD risk phenotypes (blood pressure, obesity, smoking, glucose and lipid profile) were selected, and the standard risk cut-offs were applied. The study has shown that compared to general population of Croatia, the Roma population bears a high CVD risk factors load related to smoking and high glucose level. The CVD risk factors prevalence in Roma also showed important sex and age patterns, the most imposing of which are the findings of higher prevalence of CVD risks in women (especially obesity and triglyceride levels) and the trend of higher body mass index (BMI) level in younger age group (18–34 years) which both stand in contrast to the trends characterizing the general population of Croatia. These findings are complemented by the trend of decreased risk in the oldest age group (65+ years) for all investigated CVD risk factors (with exception of triglycerides level) compared to the 50–64 age group. We conclude that the age and sex CVD risks pattern point to the health transition of this rural Roma population. As we expect the proportion of CVD in the Roma minority of Croatia to increase in the future along with further modernization of their lifestyle, the CVD prevention measures in this population are urgent and should be primarily targeted at women and at the younger segment of this population.     

Abdominal fat and risk of coronary heart disease in patients with peripheral arterial disease

Objective: We investigated whether the presence of concomitant coronary heart disease (CHD) in patients with peripheral arterial disease (PAD) can be explained by intra‐abdominal fat accumulation and compared different measures of adiposity as predictors of CHD in patients with PAD. Research Methods and Procedures: Data were collected from patients enrolled in the Second Manifestations of ARTerial disease (SMART) study, an ongoing prospective cohort study of patients with manifest vascular disease or vascular risk factors at the University Medical Centre Utrecht. The current analysis includes 315 patients, mean age 59 ± 10 years, who had PAD with (n = 79) or without (n = 236) CHD. Parameters of adiposity were measured, and intra‐abdominal fat and subcutaneous fat were measured ultrasonographically. Metabolic syndrome was defined according to Adult Treatment Panel III. Results: The prevalence of metabolic syndrome was higher among patients with CHD (63%) than among patients without CHD (48%). All parameters of adiposity indicated more fat in patients with CHD, except for subcutaneous fat. Waist circumference was associated with 64% higher prevalence of CHD (confidence interval, 20% to 123%) per 1 standard deviation increase in waist circumference after adjustment for age and sex. The odds ratio for waist circumference remained virtually the same after additional adjustment for the components of the metabolic syndrome and smoking. Discussion: An increased waist circumference, a crude measure of intra‐abdominal fat, is associated with an increased risk of concomitant CHD in patients with PAD.     

Effect of a community-based weight management program on weight loss and cardiovascular disease risk factors

Objective: The purpose of our retrospective database analysis was to describe and evaluate the outcomes of a weight loss intervention in a community medical wellness center. Research Methods and Procedures: Four hundred eighteen overweight and obese adults entered the program between 2001 and 2004. Forty‐seven percent completed the 6‐month program designed using standards and recommendations established by the NIH, the American Dietetic Association, and the American Academy of Sports Medicine. Data analysis was limited to 198 participants (142 women, 56 men) completing the program. Results: Individuals completing the 6‐month program averaged a weight loss of 7.3% in men and 4.7% in women. Fasting lipids and blood glucose improved in both genders regardless of age. Outcomes including BMI and lipids improved in women regardless of menopausal status or hormone replacement therapy. There was a significant correlation between percentage weight loss and number of weekly counseling sessions attended and number of visits to the wellness center for exercise. Discussion: Participants who complete a structured community‐based weight management program can achieve significant weight loss and improvement in cardiovascular risk factors regardless of age, gender, or menopausal status. Our analysis suggests that national treatment guidelines/recommendations for weight management can be effectively implemented in a community medical wellness center. The relatively high drop‐out rate associated with this program suggests the need to identify strategies and techniques to enhance adherence and completion of programs.     

Beliefs About Weight Gain and Attitudes Toward Relapse in a Sample of Women and Men with Obesity

Objective : The purpose of this study was to examine beliefs regarding reasons for weight gain, likely responses to weight loss relapse, notions of reasonable weight loss, and correlations between beliefs and attitudes in a large nonclinical sample of men and women with obesity. Research Methods and Procedures : Participants were 3,394 white women (n= 1,674) and men (n = 1,720) with obesity who had responded to a survey about body image and eating behaviors conducted by Consumer Reports magazine. Results : Women and men indicated that the most important reasons for their weight gain were lack of exercise and enjoying eating; the least important reason was a need to avoid social or sexual situations. Both groups reported that their most likely response to relapse is to start watching food intake, whereas their least likely response is to ask a friend, spouse, or family member for help. Women rated depression, stress, low self-esteem, and need to avoid situations as more important reasons for their weight gain than did men, and women were more likely to feel terrible and regain as a response to relapse. There was no relationship between an individual's beliefs about weight gain, responses to relapse, or notions of reasonable weight loss. Discussion : Implications of these findings for the treatment of obesity are discussed.     

Measures of adiposity and cardiovascular disease risk factors

Objective: To determine which of five measures of adiposity maintains the strongest association with cardiovascular disease risk factors. Research Methods and Procedures: A nationally representative sample of 12,608 adult participants of the third National Health and Nutrition Examination Survey were examined. Waist circumference, total body fat, percent body fat, BMI, and skinfold thickness were measured following a standardized protocol. Results: In multivariable adjusted models including waist circumference and BMI as independent variables, waist circumference was a significantly better predictor. The odds ratios (95% confidence intervals) for each standard deviation higher waist circumference and BMI for men were as follows: 1.88 (1.43, 2.48) and 0.99 (0.76, 1.29), respectively, for hypertension; 1.51 (0.87, 2.59) and 1.23 (0.76, 1.99), respectively, for diabetes; and 1.85 (1.48, 2.32) and 1.00 (0.80, 1.24), respectively, for low high‐density lipoprotein‐cholesterol. The analogous odds ratios (95% confidence intervals) for women were as follows: 2.28 (1.74, 3.00) and 0.91 (0.69, 1.19), respectively, for hypertension; 2.72 (1.85, 4.00) and 0.82 (0.55, 1.23), respectively, for diabetes; and 1.90 (1.47, 2.47) and 1.07 (0.83, 1.38), respectively, for low high‐density lipoprotein‐cholesterol. Results were markedly similar for waist circumference in models adjusting for total body fat, percent body fat, and skinfold thickness separately. In contrast, waist circumference was not a significantly better predictor of elevated C‐reactive protein than the other measures of adiposity. Discussion: Waist circumference maintains a stronger association with cardiovascular disease risk factors than other measures of adiposity.     

Minimal versus umbilical waist circumference measures as indicators of cardiovascular disease risk

Objective: Measures of central obesity are strongly correlated with cardiovascular disease (CVD) risk. Although waist circumference (WC) is a commonly used measure of central obesity, there is no standard measurement location. We examined two WC locations to determine which was more highly correlated with CVD risk factors and metabolic syndrome (MS). Research Methods and Procedures: WC measures were taken on 266 sedentary, overweight men and women 45 to 60 years old. Intravenous glucose tolerance tests, fasting plasma lipid analysis, and computed tomography scans were conducted. Correlational analyses followed by the Test for Equal Correlations determined whether one WC measure better correlated with the cardiovascular risk factors. Results: In women, minimal waist had higher correlation coefficients than umbilical waist for all eight variables presented. High‐density lipoprotein‐cholesterol, low‐density lipoprotein particle size, and MS score were significantly correlated with minimal waist, but not umbilical waist. For high‐density lipoprotein size and insulin sensitivity, minimal waist was a better correlate, although the difference between waist measures only approached statistical significance (p < 0.06). In men, minimal waist had a higher correlation coefficient than umbilical waist for insulin sensitivity, fasting insulin, and visceral adipose tissue. Additionally, minimal waist was significantly correlated with MS in men and umbilical waist was not. For both genders, minimal waist was more highly correlated with visceral adipose tissue than umbilical waist. Discussion: For every metabolic variable presented, minimal WC was more highly correlated with CVD risk than was umbilical WC in women. The data for women indicate that WC location is important when determining CVD risk. In men, minimal waist was better, although the data were less compelling.     

Developmental trajectories of overweight during childhood: role of early life factors

Objective: Our goal was to identify developmental trajectories of overweight in children and to assess early life influences on these trajectories. Research Methods and Procedures: Participants consisted of 1739 white, black, and Hispanic children who were younger than 2 years at the first survey and were followed up to 12 years of age. Repeated measures of overweight, defined as BMI ≥95th percentile, were used to identify overweight trajectories with a latent growth mixture modeling approach. Results: Three distinct overweight trajectories were identified: 1) early onset overweight (10.9%), 2) late onset overweight (5.2%), and 3) never overweight (83.9%). After adjustment for multiple potential risk factors, male gender [odds ratio (OR), 1.5; 95% confidence interval (CI), 1.0 to 2.2], black ethnicity (OR, 1.7; 95% CI, 1.1 to 2.6), maternal 25 ≤ BMI <30 kg/m² (OR, 2.2; 95% CI, 1.3 to 3.7) or ≥30 kg/m² (OR, 5.1; 95% CI, 2.9 to 9.1), maternal weight gain during pregnancy ≥20.43 kg (OR, 1.7; 95% CI, 1.0 to 2.9), and birth weight ≥4000 g (OR, 2.0; 95% CI, 1.2 to 3.4) were associated with an increased risk of early onset overweight. These risk factors, except maternal weight gain, exerted similar effects on late onset overweight. In addition, maternal smoking (OR, 1.6; 95% CI, 0.8 to 3.1) and birth order ≥3 (OR, 2.3; 95% CI, 1.0 to 5.2) were associated with an increased risk of late onset overweight only. Breastfeeding ≥4 months was associated with a decreased risk of both early (OR, 0.7; 95% CI, 0.3 to 1.3) and late onset overweight (OR, 0.7; 95% CI, 0.3 to 1.7). Discussion: Two trajectories of overweight and one never overweight group were identified. Early life predictors may have a significant influence on the developmental trajectories of overweight in children.     

Adiposity and dietary intake in cardiovascular risk in an obese population from a Mediterranean area

The aim of the study was to determine the particular relevance of android fat distribution and dietary intake in cardiovascular risk in an obese Mediterranean population with high intake of monounsaturated fatty acids (MUFA) and to compare the findings with those from normal-weight subjects. For the study, 193 subjects aged 25-60 were selected: 118 obese (BMI > or = 27 kg/m2), and 75 normal-weight (BMI < 25 kg/m2). Cardiovascular risk factors including hypertension, dyslipidaemia, glucose intolerance and insulin resistance were assessed. Nutrient intake and body fat distribution were determined. Results show that MUFA were highly consumed in the total population (21% of total energy). The obese population was normolipidemic and normoinsulinemic. However, cardiovascular risk factors (CVRF) were significantly higher than in normal-weight (P < 0.05). Obese subjects derived a greater percentage of their energy intake from total fat and lower from carbohydrates and saturated fats (P < 0.05). BMI and waist-hip ratio positively correlated with fat percentage of total energy intake and with MUFA (g/100 g fatty acids) in men, indicating that the excess of fat intake in obesity is due to a larger consumption of olive oil. CVRF were significantly and positively associated to waist circumference and WHR, both in obese and in normal-weight subjects. In conclusion, not only obesity but also android fat in normal-weight subjects are important factors in cardiovascular disease even in the Mediterranean population, with a high intake of MUFA, where these factors seem to be more relevant to cardiovascular risk than dietary composition.     

Cardiovascular and cerebrovascular risk factors and events associated with second-generation antipsychotic compared to antidepressant use in a non-elderly adult sample: results from a claims-based inception cohort study

This is a study of the metabolic and distal cardiovascular/cerebrovascular outcomes associated with the use of second-generation antipsychotics (SGAs) compared to antidepressants (ADs) in adults aged 18-65 years, based on data from Thomson Reuters MarketScan® Research Databases 2006-2010, a commercial U.S. claims database. Interventions included clinicians'' choice treatment with SGAs (allowing any comedications) versus ADs (not allowing SGAs). The primary outcomes of interest were time to inpatient or outpatient claims for the following diagnoses within one year of SGA or AD discontinuation: hypertension, ischemic and hypertensive heart disease, cerebrovascular disease, diabetes mellitus, hyperlipidemia, and obesity. Secondary outcomes included the same diagnoses at last follow-up time point, i.e., not censoring observations at 365 days after SGA or AD discontinuation. Cox regression models, adjusted for age, gender, diagnosis of schizophrenia and mood disorders, and number of medical comorbidities, were run. Among 284,234 individuals, those within one year of exposure to SGAs versus ADs showed a higher risk of essential hypertension (adjusted hazard ratio, AHR+1.16, 95% CI: 1.12-1.21, p<0.0001), diabetes mellitus (AHR+1.43, CI: 1.33-1.53, p<0.0001), hypertensive heart disease (AHR+1.34, CI: 1.10-1.63, p<0.01), stroke (AHR+1.46, CI: 1.22-1.75, p<0.0001), coronary artery disease (AHR+1.17, CI: 1.05-1.30, p<0.01), and hyperlipidemia (AHR+1.12, CI: 1.07-1.17, p<0.0001). Unrestricted follow-up results were consistent with within one-year post-exposure results. Increased risk for stroke with SGAs has previously only been demonstrated in elderly patients, usually with dementia. This study documents, for the first time, a significantly increased risk for stroke and coronary artery disease in a non-elderly adult sample with SGA use. We also confirm a significant risk for adverse metabolic outcomes. These findings raise concerns about the longer-term safety of SGAs, given their widespread and chronic use.     

Increased plasma HB-EGF associated with obesity and coronary artery disease

The mechanism by which the obese subjects are more associated with vascular disease remains unclear. We reported that the adipose tissues produce and secrete many bioactive molecules, conceptualized as adipocytokines. Heparin-binding epidermal growth factor (EGF)-like growth factor (HB-EGF), produced locally by vascular macrophages and smooth muscle cells, has been suggested to induce the migration and proliferation of vascular smooth muscle cells. The current study reveals that (1) HB-EGF mRNA is abundantly expressed in human adipose tissue, (2) HB-EGF mRNA increases in the fat tissues of obese mice, (3) plasma HB-EGF levels increase in parallel with fat accumulation in human, and (4) the subjects with coronary artery disease have higher plasma HB-EGF levels, associated with fat accumulation. These results suggest that increased plasma HB-EGF derived from the accumulated fat contributes to the higher incidence of vascular disease in obesity, proposing HB-EGF as an adipocytokine directly linking adipovascular axis.
