Aims: Excessive consumption of sugar-sweetened beverages (SSBs) may increase the prevalence of obesity and other metabolic risk factors. However, data regarding the relationship between SSB consumption and metabolic risk factors are insufficient in Chinese children. Hence, we aimed to explore the association between SSB consumption and cardio-metabolic risk factors in children aged 7–18 years living in South China.Methods: A cross-sectional study was conducted in a total of 2,032 children aged 7–18 years were enrolled, including 1,013 boys and 1,019 girls. Based on a multistage cluster sampling, five elementary and four secondary schools in Guangzhou, China were included. Fasting blood glucose levels, lipid profiles, and anthropometric characteristics were evaluated. Information on demography, dietary, and physical activities were self-reported.Results: Overall, 34.7% participants were non-drinkers and 21.6% consumed more than 120 mL/day SSB. The body mass index (19.43±0.18 kg/m2) and triglyceride concentration (0.96±0.03 mmol/L) were higher and high-density lipoprotein concentration (1.32±0.31 mmol/L) was lower in consumers than in non-consumers (all P<0.001). Furthermore, in contrast to non-consumers, the adjusted odds ratio of SSB consumption more than 120 mL/day was 2.08 (95% CI: 1.21–3.54) for obesity, 1.83 (95% CI: 1.25–2.69) for abdominal obesity, and 1.70 (95% CI: 1.02–3.06) for hypertriglyceridemia in consumers.Conclusion: A positive association between SSB consumption and the risks of obesity and hypertriglyceridemia was observed in children living in South China, which suggests that high SSB consumption enhances the risk of cardio-metabolic risk factors and the consequent cardio-metabolic diseases.

Aim: Polyunsaturated fatty acids (PUFAs) take part in various biological events linked to the pathogenesis of venous thromboembolism (VTE), including inflammation, endothelial dysfunction, and hypercoagulability. Several studies have demonstrated the association between PUFAs and the occurrence of VTE. However, the role of PUFAs in the pathogenesis of VTE remains unclear.Methods: We enrolled 45 patients with acute VTE and 37 age-, gender-, and body mass index-matched healthy volunteers to examine their PUFA levels. Serum omega 3 (eicosapentaenoic acid: EPA and docosahexaenoic acid: DHA) and omega 6 (dihomogammalinolenic acid: DGLA and arachidonic acid: AA) fatty acids levels were measured within 24 h of admission.Results: Patients with VTE showed significantly higher AA and lower EPA levels, and lower EPA/AA ratios than the controls. Multivariate analysis revealed that AA was an independent marker for VTE. In addition, we divided the patients based on their median age (58 years old). The younger patients with VTE showed significantly lower EPA/AA levels than their age-matched controls, whereas older patients with VTE showed a significantly higher AA/DGLA levels than the older controls.Conclusions: High serum AA levels and low EPA levels are associated with the development of acute VTE, suggesting that the imbalance of PUFAs may be a potential therapeutic target for preventing acute VTE.

Aim: The effect of nitroglycerin on proper arterial stiffness of the arterial tree has not been fully clarified. The cardio-ankle vascular index (CAVI), which is an application of the stiffness parameter β theory on the arterial tree from the origin of the aorta to the ankle, was developed recently. Furthermore, the stiffness of the aorta (heart-thigh β (htBeta)) and of the femoral-tibial arteries (thigh to ankle β (taBeta)) could be monitored by applying the same theory. The effects of nitroglycerin on CAVI, htBeta, and taBeta were studied comparing the values of healthy people and those of arteriosclerotic patients.Methods: The subjects were healthy people (CAVI <7.5, n=25) and arteriosclerotic patients (CAVI >9, n=25). Nitroglycerin (0.3 mg) was administrated sublingually, and various arterial stiffness indices were measured at one-minute intervals for a period of 20 minutes using Vasera VS-1500 (Fukuda Denshi, Tokyo).Results: After the administration of nitroglycerin in healthy people, CAVI decreased significantly after 5 min. [from 6.76(6.32-7.27) to 5.50(4.70-6.21), P<0.05], and recovered after 15 min. htBeta [from 5.10(4.76-5.76) to 3.96(3.35-4.79), P<0.05], and taBeta [from 14.41(10.80-16.33) to 10.72 (9.19-13.01), P<0.05] also decreased significantly. In arteriosclerotic patients, CAVI decreased after 5 min. [from 10.47(9.67-11.29) to 9.71(8.74-10.57), P<0.05] and recovered after 15 min. htBeta did not significantly change [from 12.00(11.46-13.21) to 11.81(10.14-13.83), ns], but taBeta decreased significantly [from 18.55(12.93-23.42) to 12.37(9.68-16.99), P<0.05].Conclusion: These results indicate that a nitroglycerin-induced decrease of arterial stiffness is more prominent in muscular arteries than in elastic arteries, and this effect was preserved much more prominently in arteriosclerotic patients than in healthy people.

Atherosclerosis is a chronic inflammatory disease. Interventions targeting the inflammatory process could provide new strategies for preventing atherosclerotic cardiovascular diseases (CVD). Previously, we have reported that oral administration of anti-CD3 antibodies, or active vitamin D3, reduced atherosclerosis in mice via recruiting regulatory T cells and tolerogenic dendritic cells to the gut-associated lymphoid tissues. From this, it is reasonable to propose that the intestine could be a novel therapeutic target for prevention of atherosclerotic CVD. Recently, the association between cardio-metabolic diseases and gut microbiota has attracted increased attention. Gut microbiota, reported to be highly associated with intestinal immunity and metabolism, were shown to aggravate CVD by contributing to the production of trimethylamine-N-oxide (TMAO), a pro-atherogenic compound. We have also previously investigated the relationship between patient susceptibility to coronary artery disease (CAD) and gut microbiota. We found that the order Lactobacillales was significantly increased and the phylum Bacteroidetes was decreased in CAD patients compared with control patients. In this review article, we discuss the evidence for the relationship between the gut microbiota and cardio-metabolic diseases, and consider the gut microbiota as new potential diagnostic and therapeutic tool for treating CVD.

Aim: Accumulation level of fluorescent advanced glycation end products (AGEs) in the skin can be measured non-invasively as skin autofluorescence (skin AF) by autofluorescence reader. The aim of this study was to assess possible associations between skin AF and diabetic complications, especially early-stage atherosclerosis, in Japanese type 1 diabetic patients.Methods: Skin AF was measured by AGE reader® in 105 Japanese type 1 diabetic patients (34 men and 71 women, aged 37.4±12.4 years (±SD)) and 23 age-matched healthy non-diabetic subjects. Ultrasonic carotid intima-media thickness (IMT), ankle-brachial index (ABI), and brachial ankle pulse wave velocity (baPWV) were evaluated as indices of early-stage diabetic macroangiopathy. Urinary albumin-to-creatinine ratio (UACR), the coefficient of variation of R-R intervals (CVR-R), and presence of retinopathy were also evaluated.Results: Skin AF values were significantly higher in type 1 diabetic patients than in healthy controls (2.07±0.50 (mean±SD) and 1.90±0.26, respectively, p=0.024). Skin AF was associated with carotid IMT (r=0.446, p<0.001) and baPWV (r=0.450, p<0.001), but not with ABI (r=-0.019, p=0.8488). Notably, skin AF was an independent risk factor for IMT thickening. Similarly, skin AF was associated with log (UACR) (r=0.194, p=0.049) and was an independent risk factor for UACR. Furthermore, skin AF values were significantly higher in patients with diabetic retinopathy than in those without (2.21±0.08 and 1.97±0.06, respectively, p=0.020).Conclusions: Skin AF was significantly associated with the presence and/or severity of diabetic complications and was an independent risk factor for carotid atherosclerosis.

Aims: Several guidelines propose target levels (TLs) of atherosclerotic risk factors (ARFs) to reduce atherosclerotic cardiovascular diseases; however, few data are available regarding the attainment statuses of TLs in Japan. In this study, utilizing the data obtained from the annual “Specific Health Check and Guidance in Japan” conducted from 2008 to 2011 (approximately 280,000 subjects each year), we determined TL attainments of ARFs in cardiovascular high-risk subjects.Methods: Those who had suffered from cerebrovascular disease (pCVD) or coronary heart disease (pCHD) or were receiving diabetes mellitus treatment (DM) were selected, and the rates of subjects that attained TLs of blood pressure (BP), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglycerides (TGs) and glycated hemoglobin (HbA1c) were analyzed.Results: Approximately 70% of pCVD or pCHD and 35% of subjects with DM attained TLs of BP. With regard to HbA1c, >90% of pCVD or pCHD and approximately 50% of subjects with DM attained TLs. With regard to LDL-C, <25% of pCHD females and approximately 35% of pCHD males and 50%–55% of subjects with pCVD or DM attained TLs. The TL-attainment rates of HDL-C and TGs were approximately 90% and 75%, respectively, for the three diseases. Analyses of time course changes in their attainment statuses revealed that the attainment rates of BP and LDL-C significantly improved in all the diseases.Conclusions: TL-attainment rates of BP and LDL-C were not as high as those for HDL-C, TGs, and HbA1c; however, they both showed highly significant improvements during the study period.

Recent technical innovation has enabled chemical modifications of small materials and various kinds of nanoparticles have been created. In clinical settings, nanoparticle-mediated drug delivery systems have been used in the field of cancer care to deliver therapeutic agents specifically to cancer tissues and to enhance the efficacy of drugs by gradually releasing their contents. In addition, nanotechnology has enabled the visualization of various molecular processes by targeting proteinases or inflammation. Nanoparticles that consist of poly (lactic-co-glycolic) acid (PLGA) deliver therapeutic agents to monocytes/macrophages and function as anti-inflammatory nanoparticles in combination with statins, angiotensin receptor antagonists, or agonists of peroxisome proliferator-activated receptor-γ (PPARγ). PLGA nanoparticle-mediated delivery of pitavastatin has been shown to prevent inflammation and ameliorated features associated with plaque ruptures in hyperlipidemic mice. PLGA nanoparticles were also delivered to tissues with increased vascular permeability and nanoparticles incorporating pitavastatin, injected intramuscularly, were retained in ischemic tissues and induced therapeutic arteriogenesis. This resulted in attenuation of hind limb ischemia. Ex vivo treatment of vein grafts with imatinib nanoparticles before graft implantation has been demonstrated to inhibit lesion development. These results suggest that nanoparticle-mediated drug delivery system can be a promising strategy as a next generation therapy for atherosclerotic vascular diseases.

Obesity, particularly excess visceral fat accumulation, is highly associated with the development of metabolic syndrome and atherosclerotic cardiovascular disease. Adipose tissue produces a variety of secreted proteins, referred to as adipocytokines, which directly affect nearby or remote organs. Dysregulation of adipocytokines caused by obese conditions contributes to the pathogenesis of various metabolic and cardiovascular disorders. This review focuses on the significance of several adipocytokines that potentially exert beneficial actions on obesity-related diseases, including atherosclerosis and ischemic heart disease.

Aim: Although the underlined mechanisms are still unknown, metabolic/coagulation alterations related to childhood obesity can induce vascular impairments. The aim of this study was to investigate the relationship between metabolic/coagulation parameters and endothelial function/vascular morphology in overweight/obese children.Methods: Thirty-five obese/overweight children (22 pre-pubertal, mean age: 9.52±3.35 years) were enrolled. Body mass index (BMI), homeostasis model assessment index (HOMAIR), metabolic and coagulation parameters, [adiponectin, fibrinogen, high molecular weight adiponectin (HMW), endothelin-1, and vonWillebrand factor antigen] ultrasound early markers of atherosclerosis [flow-mediated dilatation (FMD), common carotid intima-media thickness (C-IMT), and anteroposterior diameter of infra-renal abdominal aorta (APAO)] were assessed.Results: APAO was related to anthropometric (age: r=0.520, p=0.001; height: r=0.679, p<0.001; weight: r=0.548, p=0.001; BMI: r=0.607, p<0.001; SBP: r=0.377, p=0.026) and metabolic (HOMAIR: r=0.357, p=0.035; HMW: r=-0.355, p=0.036) parameters. Age, height, and systolic blood pressure were positively related to increased C-IMT (r=0.352, p=0.038; r=0.356, p=0.036; r=0.346, p=0.042, respectively). FMD was not related to any clinical and biochemical characteristics of the pediatric population. Age, HOMAIR, fasting glucose levels, and HMW were independent predictors for APAO increase. Each unit decrease in HMW concentrations (1 μg/ml) induced a 0.065 mm increase in APAO.Conclusion: High molecular weight adiponectin is related to cardiovascular risk in overweight/obese children.

Aim: In 2003, the American Diabetes Association recommended that the threshold for diagnosing impaired fasting glucose (IFG) should be lowered from 6.1 mmol/L (110 mg/dL) to 5.6 mmol/L (100 mg/dL). To discuss the diagnostic threshold for IFG, the association between fasting plasma glucose (FPG) and the risk of future diabetes must be known; however, data regarding this relation in the Japanese population are scarce. The aim of this study was to determine the relation between FPG and the risk of future diabetes in the Japanese general population.Methods: A retrospective cohort study was conducted using data from annual health check-ups performed in Omiya city. A total of 11,369 subjects between the ages of 40-79 years who were not dia-betic at baseline were followed for seven years. Diabetes was defined as FPG ≥126 mg/dL or self-report.Results: The incidence of diabetes increased as the baseline FPG level increased and a similar pattern was observed irrespective of sex or age. The hazard ratios compared with subjects with FPG <85 mg/ dL adjusted for possible confounding factors were 3.83 (95% confidence interval (95% CI); 2.41-6.08) for subjects with 100 to 104 mg/dL FPG and 7.97 (95% CI; 4.98-12.4) for subjects with 105 to 109 mg/dL FPG.Conclusions: Subjects with 100-109 mg/dL FPG have an appreciable risk of diabetes that cannot be considered as “normal” and should be notified of their potential risk of developing diabetes.

Central to the pathogenesis of ischaemic stroke are the normally protective processes of platelet adhesion and activation. Experimental evidence has shown that the ligand-receptor interactions in ischaemic stroke represent a thrombo-inflammatory cascade, which presents research opportunities into new treatment. However, as anti-platelet drugs have the potential to cause severe side effects in ischaemic stroke patients (as well as other vascular disease patients), it is important to carefully monitor the risk of bleeding and risk of thrombus in patients receiving treatment. Because thrombo-embolic ischaemic stroke is a major health issue, we suggest that the answer to adequate treatment is based on an individualized patient-centered approach, inline with the latest NIH precision medicine approach. A combination of viscoelastic methodologies may be used in a personalized patient-centered regime, including thromboelastography (TEG®) and the lesser used scanning electron microscopy approach (SEM). Thromboelastography provides a dynamic measure of clot formation, strength, and lysis, whereas SEM is a visual structural tool to study patient fibrin structure in great detail. Therefore, we consider the evidence for TEG® and SEM as unique means to confirm stroke diagnosis, screen at-risk patients, and monitor treatment efficacy. Here we argue that the current approach to stroke treatment needs to be restructured and new innovative thought patterns need to be applied, as even approved therapies require close patient monitoring to determine efficacy, match treatment regimens to each patient's individual needs, and assess the risk of dangerous adverse effects. TEG® and SEM have the potential to be a useful tool and could potentially alter the clinical approach to managing ischaemic stroke. As envisaged in the NIH precision medicine approach, this will involve a number of role players and innovative new research ideas, with benefits that will ultimately only be realized in a few years. Therefore, with this ultimate goal in mind, we suggest that an individualized patient-orientated approach is now available and therefore already within our ability to use.

Aim: Previous epidemiological studies demonstrated that the ratio of n-6 to n-3 polyunsaturated fatty acids is associated with cardiovascular diseases. We herein investigated whether the beneficial effect of highly purified eicosapentaenoic acid(EPA) on arterial stiffness is associated with changes in the ratio of polyunsaturated fatty acids, such as EPA, docosahexaenoic acid(DHA) and dihomo-γ-linolenic acid(DGLA), relative to arachidonic acid(AA), in obese Japanese patients with dyslipidemia. Methods: The EPA/AA, DHA/AA and DGLA/AA ratios were compared between obese patients with(n=94) and without (n=31) dyslipidemia. Among the former group, 88 patients received either highly purified EPA treatment(1.8g daily, n=45) or treatment without EPA(control, n=43). Results: At baseline, the ratios of DHA/AA and DGLA/AA were significantly(P<0.05) higher in obese patients with dyslipidemia than in those without, while the EPA/AA ratio was similar between patients with and without dyslipidemia. EPA significantly reduced the hemoglobin A1c, total cholesterol, triglycerides, CRP, cardio-ankle vascular index(CAVI)(an index of arterial stiffness) and the DGLA/AA ratio relative to the control at three months after the treatment. On the other hand, EPA significantly increased the adiponectin level and EPA/AA ratio(P<0.05). A multivariate regression analysis revealed that only age, an increase in the EPA/AA ratio and a decrease in the CRP level were significant determinants of a reduction of the CAVI by EPA. Conclusion: These findings suggest that EPA improves the arterial stiffness in association with an increase in the EPA/AA ratio and a decrease in inflammation in obese patients with dyslipidemia.

Aim: Whole exome sequencing (WES) is a recently developed method for discovering rare mutations associated with hereditary disorders. However, the feasibility and utilization of this method in identifying familial hypertriglyceridemia is not well known. The purpose of the study was to identify the genetic locus that causes hypertriglyceridemia and assess its prevalence in Taiwanese subjects with hypertriglyceridemia.Methods: We performed WES among two individuals with hypertriglyceridemia and one control subject in an index family (22 members). Based on the WES findings, we extended the study to genotype 65 unrelated adult index patients with a fasting serum triglyceride level of >500 mg/dL and 125 normal controls using polymerase chain reaction.Results: Using WES alignment, variant calling and annotation, 15 presumptive causal variants were initially identified, including 13 cases by the autosomal dominant model and two cases by the autosomal recessive model. Only APOA5 c.553 G>T (rs2075291), resulting in the amino acid mutation Gly185Cys, co-segregated well with hypertriglyceridemia in terms of autosomal recessive inheritance (homozygote TT: mean triglyceride level: 1,071 mg/dL vs non TT (GT and GG): mean triglyceride level: 118 mg/dL; p<0.001) in the index family. In the unrelated cohorts, the frequency of the TT genotype of rs2075291 was 12.3% in the hypertriglyceridemic group; however, no TT genotype was found in the control group.Conclusions: Our results demonstrate that WES is feasible for identifying the genetic locus that causes hypertriglyceridemia. The TT genotype of APOA5 c.553G>T acts as an important indicator of hypertriglyceridemia in patients in Taiwan.

Aims: The serum resistin level is associated with the incidence of ischemic heart disease in the general population. We analyzed the associations between serum resistin and fat intake, serum lipid concentrations and adiposity in the general population. Methods: A cross-sectional study of 6,637 randomly recruited adults was conducted. The resistin levels were measured in thawed aliquots of serum using an enzyme immunoanalysis technique. Results: The resistin level exhibited a positive nonparametric correlation with saturated fat intake(p<0.001) and an inverse correlation with adherence to the Mediterranean diet(p<0.001), monounsaturated fat intake(p<0.05), total serum cholesterol(p<0.001), non-HDL cholesterol(p<0.001), LDL cholesterol(p<0.001), body mass index(p<0.001), waist circumference(p<0.001) and the waist/height ratio(p<0.001). An elevated resistin concentration(fifth quintile) was associated with adherence to the Mediterranean diet(OR=0.82 CI95%=0.71-0.93), saturated fat intake(OR=1.34 CI95%=1.16-1.56), monounsaturated fat intake(OR=0.88 CI95%=0.78-0.99), a total cholesterol level of ≥200 mg/dL(OR=0.81 CI95%=0.72-0.91), a low HDL cholesterol level(OR=0.84 CI95%= 0.76-0.93), a high non-HDL cholesterol level(OR=0.84 CI95%=0.72-0.99), a high LDL cholesterol level(OR=0.82 CI95%=0.70-0.97) and a waist/height ratio of ≥0.55(OR=0.76 CI95%=0.67-0.85). The multivariate models corroborated the positive associations between the resistin level and saturated fat intake(p<0.001) and serum triglycerides(p=0.004) and the inverse associations between the resistin level and adherence to the Mediterranean diet(p=0.002), total serum cholesterol(p< 0.001) and cholesterol fractions and the waist/height ratio(p=0.02). Conclusions: In the general population, the serum resistin level is associated with fat intake: positively with saturated fat intake and inversely with monounsaturated fat intake. As a consequence, the resistin level is also inversely associated with adherence to the Mediterranean diet. In addition, the resistin level is inversely associated with the serum cholesterol level and adiposity.

Aim: The consumption of n-3 polyunsaturated fatty acids (PUFA), including docosahexaenoic acid DHA), reduces the incidence of cardiovascular events, and reduced serum levels of n-3 PUFA may be associated with an increased risk of cardiovascular events. However, controversy remains regarding which components of PUFA are associated with the endothelial function in patients with coronary artery disease (CAD). We therefore examined the associations between the n-3 and n-6 PUFA levels and CAD.Methods: We retrospectively reviewed 160 consecutive Japanese patients with CAD whose endothelial function was measured according to the percent change in flow-mediated dilation (FMD) and the serum levels of n-3 PUFA, including eicosapentaenoic acid (EPA) and DHA, and n-6 PUFA, including arachidonic acid (AA) and dihomo-gamma-linolenic acid (DHLA).Results: A single regression analysis showed no relationships between the FMD and the serum levels of PUFA, including EPA, DHA, AA and DHLA. In contrast, a multiple regression analysis showed that the DHA level was a positive (P<0.01) and age was a negative (P<0.001) contributor to an increased FMD; however, sex, body mass index, systolic and diastolic blood pressure, current/past smoking and the levels of HbA1c, triglycerides, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, EPA, AA and DHLA did not significantly affect the outcome.Conclusions: The serum level of DHA is associated with the endothelial function evaluated according to the FMD in patients with CAD, thus suggesting that a low serum level of DHA may be a predictive biomarker for endothelial dysfunction.

Aim: Previous clinical trials have demonstrated the effectiveness of eicosapentaenoic acid (EPA) in preventing cardiovascular events. The aim of the present study was to investigate the effects of EPA treatment on the accumulation of coronary atherosclerotic plaque using optical coherence tomography (OCT). Methods: A total of 46 acute coronary syndrome (ACS) patients without dyslipidemia were divided into two groups: those who received 1,800 mg/day of EPA (n=15) or the control group (n=31). Serial OCT examinations were performed at baseline and after eight months of follow-up. The target for the OCT analysis was non-culprit plaque with a percent diameter of stenosis of 30% to 70% in non-culprit vessels of ACS. Results: Between the baseline and follow-up visits, the serum EPA levels increased (50±26 mg/dL to 200±41 mg/dL, p<0.001) in the EPA group, although they did not change in the control group. According to the OCT analysis, the lipid arc did not change in the EPA group (131±52 degrees to 126±54 degrees, p=0.106) or the control group (137±50 degrees to 138±50 degrees, p=0.603). In contrast, the fibrous cap thickness significantly increased in both the EPA group (169±70 μm to 201±49 μm, p<0.001) and the control group (164±63 μm to 174±72 μm, p=0.018); however, the relative change in the fibrous cap thickness was significantly greater in the EPA group than in the control group (131±35% vs. 106±15%, p=0.001). Conclusions: In the present study, the administration of EPA for eight months significantly increased the fibrous cap thickness in patients with coronary atherosclerotic plaque.

Aim: The aim of this study, the YOung TAiwanese Cohort (YOTA) Study, was to investigate the relationship between a childhood overweight/obese status and young adult preclinical atherosclerosis, including assessments of the carotid intima-media thickness (CIMT) and prehypertension or hypertension. Methods: From among children who participated in the 1992-2000 mass urine screening program in Taiwan, we recruited 303 subjects with an elevated blood pressure (EBP) and 486 subjects with a normal BP in childhood during the period of 2006-2008. These 789 young adults received health check-ups for cardiovascular health, including examinations of blood and urine parameters, anthropometrics, BP and the CIMT, a subclinical cardiovascular risk index. Data analyses were used to evaluate the associated risks in both childhood and young adulthood. Results: The school students with a childhood overweight/obese status had a higher risk of prehypertension or hypertension, with a relative risk of 3.20 (1.40-7.33) for being overweight and 6.51 (3.36-12.63) for being obese in young adulthood at an average age of 21. A childhood overweight/obese status also predicted a higher risk of having a thicker CIMT, with a relative risk of 2.82 (1.26-6.28) and 4.17 (2.21-7.85) for being overweight and obese in adulthood, respectively, after a mean follow-up of 8.5 years. The body mass index exhibited a consistent trend from childhood to adulthood, with an adjusted R square of 0.551. The participants who were not overweight/obese in childhood also demonstrated a higher risk of prehypertension or hypertension if they became overweight or obese in adulthood. Conclusions: This study highlights the importance of preventing and treating an overweight or obese status in childhood for the primary prevention of cardiovascular disease in adulthood.

Aim: The ankle-brachial index(ABI) is an easy-to-use, non-invasive and reliable diagnostic tool for assessing peripheral arterial occlusive disease(PAOD). The CHADS2(congestive heart failure, hypertension, age ≧75 years, diabetes, prior stroke) score is a simple and popular clinical parameter that is used to assess the risk of stroke in patients with atrial fibrillation(AF). Because all five components of the CHADS2 score are risk factors for PAOD, the score should have a strong correlation with the presence of PAOD. However, there are limited studies regarding the association between the CHADS2 score and PAOD in patients without AF. Therefore, the aim of the present study was to investigate whether the CHADS2 score is positively associated with PAOD in patients without AF. Methods: A total of 1,320 patients without AF were included in this study. The ABI was measured using an ABI-form device. PAOD was defined as an ABI of <0.9 in either leg. Results: Among the 1,320 subjects(mean age: 60.3±13.4 years), the prevalence of an ABI of <0.9 was 5.7%. A multivariate analysis showed that an increased age(odds ratio [OR], 1.054; p<0.001), decreased estimated glomerular filtration rate (OR, 0.971; p<0.001) and increased CHADS2 score(OR, 1.861; p<0.001) were independently associated with an ABI of <0.9. Conclusions: Our study demonstrated that the CHADS2 score is significantly associated with an ABI of <0.9 in non-AF patients. Further prospective studies are needed to examine the ability of the CHADS2 score to predict the incidence of PAOD.
