Abstract
There are several patterns of epidemiological study in Japan. One is the international collaborative studies, such as Seven Countries Study, NI-HON-SAN Study, International Study of Salt and Blood Pressure (INTERSALT), International Study of Macro-and Micro-nutrients and Blood Pressure (INTERMAP), and Monitoring of Cardiovascular Disease (MONICA). The next one is the several cohort studies in Japanese unique surveys, such as Hisayama Study, Osaka-Akita Study, Tanno-Sobetsu Study, Suita Study, Ohazama Study, National Integrated Project for Prospective Observation of Noncommunicable Disease and Its Trends in the Aged (NIPPON DATA), Japan Collaborative Cohort (JACC), and Japan Public Health Center-Based Study (JPHC). Finally, some recent special meta-analysis in Japan are Japan Arteriosclerosis Longitudinal Study (JALS) and Evidence for Cardio-vascular Prevention from Observational Cohorts in Japan (EPOCH-JAPAN). The aim of this review is to introduce the history of epidemiologcal study, especially, cardiovascular epidemiology from the mid-20th century to in the early 21st century by dividing three patterns.

Abstract
AIMS Serum uric acid increases with metabolic disorders; however, whether the effects of uric acid on atherosclerosis are different in females and males has not been sufficiently evaluated. Therefore, this study compared the impact of uric acid on arterial stiffness and atherosclerosis between females and males. METHODS We enrolled 10196 untreated middle-aged subjects (46±8 years, 3021 females and 7175 males) who underwent periodic health check-ups. Serum uric acid levels were measured and arterial stiffness and atherosclerosis were assessed by the cardio-ankle vascular index (CAVI), carotid intima-media thickness (IMT), and plaque, using ultrasound imaging. RESULTS Females with increased arterial stiffness (CAVI ≥ 8.0) or carotid plaques had higher uric acid than those without (P<0.0001), but males did not. In multivariable regression analyses including overall participants, uric acid was significantly associated with the CAVI, where sex interacted with uric acid. In sex-specific analyses, uric acid was significantly associated with the CAVI, but not with carotid IMT, in both sexes. However, logistic regression analyses revealed that serum uric acid was independently associated with the presence of carotid plaques in females. The exclusion of subjects with abdominal obesity or metabolic syndrome from the analysis did not alter the results in females. CONCLUSIONS Serum uric acid was significantly associated with the CAVI in both sexes, but the interaction of sex was confirmed and associated with a carotid plaque only in females. These findings support the increased impact of serum uric acid on arterial stiffness and atherosclerosis in females.

Abstract
AIMS Small arteries can be visualized in the ocular fundus, and findings of retinopathy based on Scheie classification are often applied to evaluate the impact of hypertension and atherosclerosis. However, the relationship between damage in the large and small arteries has not been investigated sufficiently, especially in the early stages. The present study investigated possible associations between large artery atherosclerosis and small artery retinopathy in untreated middle-aged individuals. METHODS Untreated middle-aged workers undergoing periodic health check-ups (n=7,730, 45±8 years) were enrolled in this study. The absence or presence and extent of retinopathy were characterized by ophthalmologists as hypertensive (H0-4) and atherosclerotic grades (S0-4) based on Scheie classification. Large artery atherosclerosis was examined based on functional assessment of the cardio-ankle vascular index (CAVI) and morphological assessment of the carotid intima-media thickness (IMT) by ultrasound. RESULTS We found significant differences in CAVI and carotid IMT between individuals with and without hypertensive or atherosclerotic retinopathy. Multivariable regression analysis showed that the presence of hypertensive and atherosclerotic retinopathy was significantly associated with CAVI and carotid IMT. Logistic regression analysis with the endpoint of a hypertensive or atherosclerotic lesion revealed that CAVI and carotid IMT are independent determinants of retinopathy. CONCLUSIONS CAVI and carotid IMT were significantly associated with the presence of retinopathy based on Scheie classification in untreated middle-aged subjects, implying that atherosclerotic examination in large arteries could reveal early-stage small artery retinopathy.

Abstract
Abstract
Background
China bears the largest global stroke burden, yet little is known about its rates in Chongqing, southwest China. We aimed to investigate the prevalence and related risk factors for stroke in Chongqing, and to provide evidence for improved formulation of targeted primary preventive measures for stroke.
Methods
In 2015, a cross-sectional study was conducted in Nan’an district, Chongqing. Participants responded to a questionnaire surveying general information and common risk factors for stroke, and related physical examinations were conducted.
Results
Of 25,000 people aged ≥ 40 years who were investigated, 24,859 participants completed the questionnaire and underwent the physical examination. The crude prevalence rate for stroke was 1.71%, and was higher in men than in women (1.9% versus 1.6%). Prevalence rates increased with age (p < 0.001). Multiple logistic regression analysis indicated that too little exercise, hypertension, family history of stroke, and history of transient ischemic attack were stroke risk factors among three groups (men, women, and total participants; all p-values < 0.05). Smoking was a risk factor for men (odds ratio 2.77; 95% Cl 1.46–5.28) and having only attained a primary school or lower education level was a risk factor for women (p < 0.05).
Conclusions
These findings suggest that controlling stroke risk factors for stroke prevention is still crucial. Moreover, this study provides comprehensive resource data for further stroke research in southwest China.

Abstract
The effect of a history of cancer on the prognosis of patients with acute myocardial infarction (AMI) after percutaneous coronary intervention (PCI) is poorly understood.From the Osaka Acute Coronary Insufficiency Study (OACIS) registry in Osaka, Japan, we enrolled the case data of a total of 3499 patients with AMI treated with PCI between 1998 and 2014, of whom 462 had a cancer history (cancer group, 13.2%) and 3037 did not (non-cancer group, 86.8%). All of the cases were followed for up to five years from discharge.The Kaplan-Meier curve and multivariate analysis using Cox proportional hazards models revealed that all-cause mortality was significantly higher in the cancer group than in the non-cancer group (adjusted hazard ratio [HR], 2.43; P < 0.001). Deaths from cardiac, cancer, and other causes were treated as competing events, and competing analysis using the cumulative incidence function (CIF) and Fine-Gray model revealed that mortality due to cancer was higher in the cancer group than in the non-cancer group, whereas cardiac mortality was similar between the two groups. The incidences of cardiovascular events, including stroke, recurrent infarction, and heart failure requiring readmission, were also similar between the two groups, although the Kaplan-Meier analysis and univariate Cox proportional hazards model revealed that the incidence of stroke was higher in the cancer group than in the non-cancer group.A history of cancer increased all-cause and cancer mortality among patients with AMI treated with PCI, although it was not associated with cardiovascular events.

Abstract
BACKGROUND Obesity is a public health problem worldwide. To widely disseminate weight-loss interventions across the target population, a cost-effective approach is needed. OBJECTIVE We aimed to test whether a single motivational lecture could promote weight loss. METHODS Our study was a 3-month randomized controlled trial, and we recruited participants via local newspaper advertisements in 3 cities in Ibaraki Prefecture, Japan, and randomly assigned them to a control group (no intervention) and an intervention group, who attended a single motivational lecture lasting approximately 2 h. No other lectures or textbooks were provided. The eligibility criteria included an age of 40-64 years, a body mass index (BMI) of 25-40 kg/m2, and the presence of at least 1 component of metabolic syndrome. The primary outcome was body weight change at 3 months. RESULTS We enrolled 145 eligible participants with a mean age of 53.8 ± 7.1 years and a BMI of 28.5 ± 3.1 kg/m2. The 3-month body weight change in the control and intervention groups was -0.65 kg (95% confidence interval [CI] -1.09 to -0.20) and -2.48 kg (95% CI -3.01 to -1.95), respectively. The between-group difference was 1.83 kg (95% CI 1.15-2.51). CONCLUSIONS The significant difference suggested that a single motivational lecture is an effective option to promote modest weight loss in the short term.

Abstract
This study aimed to examine the cross-sectional association of non-standard employment with cardiovascular disease risk factors. Five yr of data from the Comprehensive Survey of Living Conditions and National Health and Nutritional Survey were combined. We used logistic regression to examine the association of employment contract (non-standard [part-time, dispatched, or contract] vs. standard [full-time and permanent]) with eight cardiovascular disease risk factors among 1,636 men and 2,067 women aged 40-60 yr. There were significant associations between non-standard employment and cardiovascular disease risk factors such as current smoking among men (odds ratio [OR] 1.39; 95% confidential interval [CI], 1.13-1.86) and diabetes among women (OR 1.83; 95% CI, 1.10-3.09). Non-standard employment was associated with a few cardiovascular disease risk factors in this middle-aged cohort in Japan.

Abstract
Atherosclerosis, a chronic inflammatory disease in arterial blood vessels, is one of the major causes of death in worldwide. Meanwhile, periodontal disease is a chronic inflammatory disease caused by infection with periodontal pathogens such as P. gingivalis (Porphyromonas gingivalis). Several studies have reported association between periodontal infection and atherosclerosis, but direct investigation about the effects of periodontal treatment on atherosclerosis has not been reported. We have planned Japanese local clinics to determine the relationship between periodontal disease and atherosclerosis under collaborative with medical and dental care. A prospective, multicentre, observational study was conducted including 38 medical patients with lifestyle-related diseases in the stable period under consultation at participating medical clinics and 92 periodontal patients not undergoing medical treatment but who were consulting at participating dental clinics. Systemic and periodontal examinations were performed before and after periodontal treatment. At baseline, LDL-C (low-density lipoprotein cholesterol) levels and percentage (%) of mobile teeth were positively related to plasma IgG (immunoglobulin) antibody titer against P. gingivalis with multivariate analysis. Corresponding to improvements in periodontal clinical parameters after treatment, right and left max IMT (maximum intima-media thickness) levels were decreased significantly after treatment (SPT-S: start of supportive periodontal therapy, SPT-1y: at 1 year under SPT, and SPT-3y: at 3 years under SPT). The present study has clarified our previous univariate analysis results, wherein P. gingivalis infection was positively associated with progression of atherosclerosis. Thus, routine screening using plasma IgG antibody titer against P. gingivalis and periodontal treatment under collaborative with medical and dental care may prevent cardiovascular accidents caused by atherosclerosis.

Abstract
Aim In addition to atherosclerosis, impairment of blood rheology is an important factor in cardiovascular events. The present study attempted to clarify the relationship between hemorheology and cardiovascular risk factors in patients with type 2 diabetes mellitus assessed by a microchannel method. Methods We enrolled 294 patients with type 2 diabetes mellitus (109 males and 185 females; mean age, 69 ± 11 years) with no history of cardiovascular events. Hemorheology was evaluated with a microchannel array flow analyzer, and the relationship between whole-blood passage time (WBPT) and various clinical parameters was examined. Results WBPT was significantly correlated with advanced glycation end-product (AGE) levels at the skin (r = 0.49, p < 0.001), serum reactive oxygen metabolite concentrations (oxidative stress markers) (r = 0.25, p < 0.001), the cardio-ankle vascular index (CAVI, arterial function marker) (r = 0.32, p < 0.001), and a number of classical cardiovascular risk factors in an individual (r = 0.45, p < 0.001). Multiple regression analysis revealed that these factors were selected as independent variables for WBPT as a subordinate factor. Conclusion Hemorheology is significantly associated with novel cardiovascular risk factors, such as AGEs, in vivo oxidative stress, and CAVI, and clustering of classical cardiovascular risk factors in patients with type 2 diabetes mellitus.

Abstract
We assessed the safety and tolerability of ascending single doses of alirocumab in healthy Japanese subjects and evaluated the effect of alirocumab at 3 doses (50, 75, 150 mg) on low-density lipoprotein cholesterol (LDL-C) reduction in patients with primary hypercholesterolemia on atorvastatin. A randomized, single ascending-dose study of alirocumab (100, 150, 250, or 300 mg) or placebo (3:1 ratio), administered subcutaneously, was conducted in 32 healthy Japanese men. The phase 2, randomized, double-blind, placebo-controlled, parallel-group study was performed in patients with primary hypercholesterolemia (defined as calculated LDL-C ≥100 mg/dl [2.6 mmol/l]) who were on a stable dose of atorvastatin (5 to 20 mg). Patients were randomized to alirocumab (50, 75, or 150 mg) or placebo (in single 1.0-ml injection volumes) administered every 2 weeks (Q2W) for 12 weeks; the primary outcome was the mean percent change in calculated LDL-C from baseline to week 12. Single subcutaneous administration of alirocumab in healthy subjects was well tolerated over 15 weeks and resulted in highest mean percent reductions in LDL-C from baseline of approximately 40% to 60%. In the multiple-dose study, least-square mean (SE) changes in calculated LDL-C concentrations from baseline to week 12 were -54.8% (3.1%) for alirocumab 50 mg, -62.3% (3.1%) for alirocumab 75 mg, and -71.7% (3.1%) for alirocumab 150 mg, with a least-square mean (SE) difference versus placebo of -52.2% (4.3%), -59.6% (4.3%), and -69.1% (4.3%), respectively (all p <0.0001). In conclusion, alirocumab was well tolerated and significantly reduced LDL-C concentrations in Japanese patients with primary hypercholesterolemia on atorvastatin.

Abstract
BACKGROUND/OBJECTIVES Recent studies have reported an association of the angiotensin II type 2 receptor (AT2R) 3123Cytosine/Adenine (3123C/A) polymorphism with essential hypertension and cardiovascular diseases. The purpose of the study was to investigate whether the AT2R 3123C/A polymorphism affects blood pressure for free-living hypertensive men during a 5-month intervention period. SUBJECTS/METHODS The subjects were free-living hypertensive Japanese men aged 40 to 75 years who agreed to intervention in the period from 2004 to 2011. Detection of the AT2R 3123C/A polymorphism was determined by polymerase chain reaction. The dietary intervention was designed to decrease salt level and to increase potassium level through cooking instructions and self-monitoring of the diet. The exercise session consisted of activities such as stretching, resistance training, and walking. Blood pressure, urinary sodium and potassium excretion, dietary and lifestyle data, and non-fasting venous blood sample were collected at baseline and after the intervention period. RESULTS Thirty nine subjects were eligible for participation and the follow-up rate was 97.4%. The C allele proportion was 57.9%. AT2R 3123C/A polymorphism was X-chromosome-linked, therefore we analyzed the C and A genotypes. At baseline, no significant differences were observed between the genotype groups. After the intervention, there were no significant differences in lifestyle habit between the groups. Nevertheless, the estimated salt excretion (g/day) was significantly decreased only in the C genotype (13.0-10.3, P = 0.031). No significant change was observed in systolic blood pressure (SBP) (mmHg) in the A genotype, but a significant decrease was observed in the C genotype (150.0-141.5, P = 0.024). CONCLUSTIONS In the C genotype, it might be easy to improve SBP through lifestyle intervention in free-living hypertensive Japanese men, however generalization could not be achieved by the small sample size.

Abstract
Human umbilical vein endothelial cell (HUVEC)-based gene expression studies performed under hypoxia and/or hyperglycemia show huge potential for modeling endothelial cell response in cardiovascular disease and diabetes. However, such studies require reference genes that are stable across the whole range of experimental conditions. These reference genes have not been comprehensively defined to date. We applied human genome-wide microarrays and quantitative real-time PCR (qRT-PCR) on RNA obtained from primary HUVEC cultures that were incubated for 24 hr either in euglycemic or in hyperglycemic conditions and then subjected to short-term CoCl2-induced hypoxia for 1, 3, or 12 hr. Using whole-transcript arrays, we selected 10 commonly used reference genes with no significant expression variation across eight different conditions. These genes were ranked using NormFinder software according to their stability values. Consequently, five genes were selected for validation by qRT-PCR. These were ribosomal protein large P0 (RPLP0), transferrin receptor (TFRC), glyceraldehyde-3-phosphate dehydrogenase (GAPDH), β-glucuronidase (GUSB), and β-actin (ACTB). All five genes displayed stable expression under hyperglycemia. However, only RPLP0 and TFRC genes were stable under hypoxia up to 12 hr. Under hyperglycemia combined with hypoxia up to 12 hr, the expression of RPLP0, TFRC, GUSB, and ACTB genes remained unchanged. Our findings strongly confirm that RPLP0 and TFRC are the most suitable reference genes for HUVEC gene expression experiments subjected to hypoxia and/or hyperglycemia for the given experimental conditions. We provide further evidence that even commonly known references genes require experimental validation for all conditions involved.

Abstract
Aims/Introduction: To examine the cross‐sectional relationship between sleep duration and impaired glucose tolerance (IGT), including diabetes mellitus (DM), we analyzed a large‐scale healthy workers database in Japan. Materials and Methods: We examined the baseline database of 4143 participants (3415 men and 728 women) aged 19–69 years. Sleep duration of participants was categorized into four groups: <6, 6 to <7, 7 to <8 and ≥8 h. The physical activity of each participant was classified according to the International Physical Activity Questionnaire (IPAQ). We defined IGT including DM (IGT/DM) in the present study according to previous studies as follows: fasting blood sugar level ≥110 mg/dL, or if <8 h after meals ≥140 mg/dL, or on medication for diabetes mellitus, or those diagnosed as having DM. Logistic regression was applied to estimate the odds ratio (OR) to examine the relationship between IGT/DM, sleep duration and other related factors. Results: The number of participants with IGT/DM was 402 (9.7%). The factors that significantly associated with IGT/DM were age (OR 1.08, 95% confidence interval [CI] 1.07–1.10, P < 0.001), high blood pressure (OR 1.94, CI 1.52–2.47, P < 0.001), and <6 h of sleep duration in comparison with 6 to <7 h sleep (OR 2.32, CI 1.18–4.55, P = 0.015). The associations of difficulty in sleep initiation, IPAQ classification, current smoking and alcohol intake with IGT/DM were not statistically significant. Conclusions: Our results showed that shorter sleep duration (<6 h of sleep duration per night) was associated with a risk of IGT/DM independent of other lifestyle habits and metabolic risk factors.

Abstract
BACKGROUND Rheumatoid arthritis (RA) increases the mortality and morbidity of cardiovascular disease (CVD). However, the relationship between RA and the risk of CVD in the Japanese population remains unclear. METHODS AND RESULTS This study comprised 571 RA patients who were admitted to Juntendo University Hospital from January 1990 to December 2000. Cardiovascular events (CVEs) were defined as cardiac death, acute coronary syndrome (ACS), symptomatic stroke, and congestive heart failure. During follow-up (mean 11.7 ± 5.8 years), 7.5% of the patients died from all causes and 11.0% experienced CVEs. The morbidity of stroke and ACS was 3.6 and 2.5 per 1000 person-years, respectively. The mean RA disease duration at enrolment was significantly longer in patients who experienced CVEs than in those who did not experience CVEs (15.0 ± 12.7 years vs. 10. 8 ± 9.7 years; p = 0.01). Physical disabilities due to RA were more severe in patients who experienced CVEs than in those who did not experience CVEs. Patients with a long RA disease duration showed significantly higher event rates (p = 0.033). Cox proportional hazards analysis identified a longer RA duration as an independent risk factor for CVD (hazard ratio 1.57, 95% CI 1.09-2.30, p = 0.02). CONCLUSION Japanese RA patients showed a relatively high incidence of CVD, despite the fact that they had few coronary risk factors. The RA disease duration was an independent risk factor for CVEs.

Abstract
AIM To examine the relationship between the type of work and the number of metabolic syndrome diagnostic components(MetS-DC), as well as the risk of MetS, with adjustment for lifestyle habits in Japanese workers. METHODS We examined the baseline data from 4,427 participants(81.4% male) aged 19 to 69 years old. The physical activity of each participant was classified according to the International Physical Activity Questionnaire(IPAQ). We defined the four MetS-DC in this study as follows: 1) high blood pressure(BP): systolic BP ≥130 mmHg, or diastolic BP ≥85 mmHg, or the use of antihypertensive drugs; 2) dyslipidemia: high-density lipoprotein-cholesterol concentration <40 mg/dl or triglyceride concentration ≥150 mg/dl, or on medication for dyslipidemia; 3) dysglycemia: fasting blood sugar level ≥110 mg/dl, or if less than eight hours after meals ≥140mg/dl, or on medication for diabetes mellitus; 4) overweight: a body mass index ≥25kg/m(2). We defined MetS as overweight plus two or more of the MetS-DC. RESULTS There were 3,094 subjects in the daytime work group, 73 in the fixed nighttime work group, 1,017 in the shift work group and 243 in the day-to-night work group. The Poisson regression analysis revealed that fixed nighttime (regression coefficient [b]=-0.233, P=0.028) and shift work (b=0.098, P=0.034) independently contributed to the number of MetS-DC, compared to daytime work. The multivariate logistic analysis not including sleep hours in the model showed that shift work was positively related to MetS (odd ratio=1.47, P<0.01). CONCLUSION Shift work were significantly associated with the number of MetS-DC, and was related to risk of MetS compared to daytime work.

Abstract
OBJECTIVE Our previous study, a 6-month randomised controlled trial, demonstrated that a group-based support promoted weight loss as compared to an education-only intervention. The purpose of this study was to examine weight loss maintenance for 2 years. METHODS Originally, 188 overweight Japanese adults, aged 40-65 years, were randomly assigned to 3 groups: control, education-only or group-based support. After the 6-month intervention, 125 participants in the education-only and the group-based support groups were followed up for 2 years. The primary outcome was the amount of weight lost. The participants were retrospectively grouped into quartiles of percent weight loss for secondary analyses. RESULTS At the end of follow-up, the amount of weight lost in the education-only and the group-based support groups was the same (3.3 kg). Secondary analyses using data of those who completed the study (n = 100) revealed that the participants in the highest quartile of percent weight loss significantly increased their step counts and moderate-to-vigorous physical activity compared with the lowest quartile. No significant differences were observed in the energy intake among the four groups. CONCLUSION The effects of group-based support disappear within 2 years. Increasing physical activity may be a crucial factor for successful maintenance of weight loss.

Abstract
BACKGROUND Obesity is associated with insulin resistance, development of diabetes, and coronary heart disease. There is limited information on the contribution of previous obesity on the risk of coronary heart disease. We aimed to examine the effect of previous history of obesity on the occurrence of coronary heart disease in patients with diabetes. METHODS We carried out a retrospective chart analysis of 315 type 2 diabetic patients without obesity and without atherosclerotic cardiovascular events at their initial hospital visit (men/women 236/79; mean ± standard deviation; age 53.1 ± 6.6 years; maximal body mass index before enrollment (MAXBMI) 26.6 ± 3.4 kg/m2; decrease of the BMI at enrollment from MAXBMI (deltaBMI) 4.23 ± 2.62 kg/m2) to investigate the association of previous obesity (MAXBMI larger than 30 kg/m2) with the long-term incidence of cardiovascular events. Of 315 patients, forty-eight were previously obese. RESULTS After median follow-up of 13.9 years, 48 patients developed coronary heart disease. The Kaplan-Meier analysis exhibited that coronary heart disease occurred more frequently in previously obese patients than in subjects in the reference category (22 kg/m2 < or = MAXBMI < 25 kg/m2) and that the effect lasted proportionally over follow-up periods. Multivariate Cox regression models showed that hazard ratios and corresponding 95% confidence intervals of coronary heart disease for patients with previous obesity compared with subjects in the reference category were 2.52 and 1.15 to 5.50 (p value = 0.020) after adjustment for age, sex, smoking status, systolic blood pressure, total cholesterol and HDL cholesterol. In this cohort, deltaBMI strongly correlated with MAXBMI and also behaved as a risk factor. The hazard ratios and 95% confidence intervals by the increment of one standard deviation of deltaBMI after adjustment for age, sex, smoking status, systolic blood pressure, total cholesterol and HDL cholesterol were 1.38 and 1.08 to 1.79 (p value = 0.013). CONCLUSIONS Previous obesity and/or large body weight loss before admission might act as an increased risk for coronary heart disease.

Abstract
STUDY DESIGN A cross-sectional multicenter observational study. OBJECTIVE To identify associations between lumbar spinal stenosis (LSS) and lifestyle-related diseases. SUMMARY OF BACKGROUND DATA Impaired blood flow as a result of arteriosclerosis facilitates degenerative changes in the spine. However, associations between LSS and lifestyle-related diseases (hypertension, diabetes, and dyslipidemia) remain unclear. METHODS Participants comprised 526 patients diagnosed with LSS using the clinical diagnostic support tool and magnetic resonance imaging at 64 facilities. Data on 1218 males and 1636 females in the general population were selected from the 2006 National Health and Nutrition Survey as control data. We investigated the prevalence of lifestyle-related diseases (hypertension, diabetes, and dyslipidemia) and levels of hemoglobin A1c, total cholesterol, and high-density lipoprotein cholesterol. LSS and control groups were divided into 4 subgroups by age (nonelderly, <70 yr old; elderly, ≥ 70 yr) and sex. Statistical analyses were performed to compare patients with LSS and the control group using the χ test or Fisher exact text. Values of P < 0.05 were considered statistically significant. RESULTS Among nonelderly patients, proportions of patients with hypertension and diabetes mellitus were higher in patients with LSS than in controls (P < 0.01 each). The proportion of patients with hemoglobin A1c was 6.1% or greater and higher for female patients with LSS than for female controls (P < 0.05). No significant difference in the proportion of patients with dyslipidemia was apparent between the LSS and control groups. CONCLUSION After adjusting for age and sex, this study revealed a close association between diabetes and hypertension in 50- to 69-year-old patients with LSS. Physicians should consider the possibility of concomitant hypertension or diabetes mellitus when examining 50- to 69-year-old patients with LSS.

Abstract
As the life expectancy of people with intellectual disability (ID) increases, it is becoming necessary to understand factors affecting survival. However, predictors that are typically assessed among healthy people have not been examined. Predictors of all-cause mortality, including blood, urine, anthropometry, and nutritional indices, were examined among institutionalized people with ID. This retrospective cohort study involved 316 participants (191 males, 125 females; mean age, 36.5 ± 10.5 years) at a public facility for people with ID in Ibaraki Prefecture, Japan. During the follow-up from the examination day in 1984-1992 through December 31, 2007 (mean follow-up, 18.6 years), 44 deaths occurred. Mean age at death was 47.1 ± 10.0 years (range, 22.3-65.3 years). Early deaths within three years (n = 4) were treated as censored cases. Cox proportional hazard regression models were used to calculate hazard ratios (HRs) and 95% confidence intervals (CIs) of all-cause mortality. Sex- and age-adjusted analysis (p<0.15) revealed positive associations with mortality for high serum cholesterol, high thymol turbidity test (TTT), and glucosuria and negative associations with mortality for high serum albumin, high uric acid, high potassium, high calcium, and high systolic blood pressure. Multivariate analysis revealed that male sex (HR, 4.11; 95% CI, 1.59-10.59), high serum cholesterol (1.01; 1.00-1.02), high serum TTT (1.21; 1.03-1.41), and epilepsy significantly increased the mortality risk. The results indicate that the predictors of life expectancy for people with ID included both factors that are shared with healthy people (male sex, high serum cholesterol) and factors specific to people with disabilities (high serum TTT and epilepsy).

Abstract
BACKGROUND Limited data are available regarding the relationship between age and the effect of HMG-CoA reductase inhibitor (statin) treatment. OBJECTIVE The aim of the present analysis was to evaluate the relationships between age, baseline patient characteristics, and pravastatin treatment with respect to the development of cardiovascular disease (CVD) in the Management of Elevated Cholesterol in the Primary Prevention Group of Adult Japanese (MEGA) study, a large-scale clinical study conducted in Japanese patients with mild or moderate hyperlipidaemia to evaluate the primary preventive effect of pravastatin against coronary heart disease. METHODS To compare the prevalence of CVD risk factors, the incidence of CVD in relation to each risk factor, and final values and changes in lipid parameters, the 7832 patients were classified into six age groups: <45, 45-49, 50-54, 55-59, 60-64 and ≥65 years. The relationship between pravastatin (10-20 mg/day) treatment efficacy and aging and the incidence of events in relation to the age groups were compared using the multivariable Cox proportional hazards model. RESULTS The prevalences of diabetes mellitus and hypertension were higher in older men than in younger men, while the prevalences of smoking and obesity were higher in younger men. However, a similar difference in risk factors was not seen in women. High-density lipoprotein cholesterol was higher in women than in men across all age groups. Triglycerides were higher in younger men than in older men and all groups of women. The mean follow-up levels of total cholesterol and low-density lipoprotein cholesterol were lower in older patients than in younger patients. Pravastatin (10-20 mg/day) reduced the risk of CVD by about 30-40% across all age groups, and there was no difference between men and women. Of particular note in this analysis, CVD risk was markedly reduced in older women compared with younger women (53% vs 30% in women aged ≥65 vs ≥45 years). CONCLUSION A similar satisfactory risk reduction for CVD was achieved with low-dose pravastatin in all men and in older women in particular, despite differences in the prevalence of risk factors.

Abstract
AIM To analyze the risk of coronary heart disease in patients with type 2 diabetes mellitus (T2DM) receiving standard medical treatment. METHODS We performed a retrospective chart analysis of 269 middle-aged patients (age 45-64 years, mean age, 53.9 ± 5.5 years) with T2DM and without atherosclerotic cardiovascular events who underwent typing to determine their apolipoprotein E (apoE) isoforms. The apoE isoforms were determined using isoelectric focusing, followed by immunoblotting. We retrospectively evaluated the charts of the 269 patients, recorded between their first visit to the hospital (the study's start point, between 1987 and 1992) and the occurrence of an atherosclerotic cardiovascular event (the study's endpoint) or January 2004, whichever came first. The age-adjusted mean values and the prevalences of covariates were calculated to compare the laboratory data among the apoE phenotypes. To investigate the association of risk factors with the incidence of coronary heart disease during the follow-up period, monovariate and multivariate Cox regression models were used. RESULTS At enrollment, the mean serum low density lipoprotein (LDL) cholesterol levels were lowest (2.92 ± 0.89 mmol/L) among the subjects with apoE2 (apoE2/2 or apoE2/3) and highest (3.52 ± 0.77 mmol/L) among the subjects with apoE4 (apoE3/4 or apoE4/4). No significant differences in mean age or the percentage of smokers were observed among the three groups. Furthermore, no significant differences were observed in the systolic and diastolic blood pressures, body mass index, HbA1c level or serum triglyceride levels among the three groups. There were 47 cases of coronary heart disease over 3285 person-years of follow-up. An age-adjusted multivariate Cox proportional model identified diabetic retinopathy (hazard ratio, 2.38, 95% CI: 1.28-4.43, P = 0.006), a high systolic blood pressure (hazard ratio, 1.04, 95% CI: 1.02-1.06, P < 0.001) and high HbA1c values (hazard ratio, 1.19, 95% CI: 1.02-1.38, P = 0.0029), but not the LDL cholesterol value at enrollment (hazard ratio, 1.01, 95% CI: 0.97-1.05, P = 0.77) nor the specific apoE isoform, as significant predictors of coronary heart disease. CONCLUSION Under standard medical treatment of diabetes, including the control of LDL cholesterol levels, the apoE4 isoform was not associated with coronary heart disease among T2DM patients.

Abstract
AIM Heterozygous patients with familial hypercholesterolemia (FH) are known to be associated with a high risk of coronary artery disease (CAD), which is a major determinant of their clinical outcome. The prognosis of heterozygous FH patients substantially varies, being dependent on the level of their CAD risk, and their therapeutic regimen should be individualized. We assessed critical levels of LDL-cholesterol (LDL-C) and Achilles tendon thickness (ATT) to identify heterozygous FH patients at "very high" risk for CAD. METHODS One hundred and nine heterozygous FH patients who had no history of CAD and had had their plasma lipid profile and ATT assessed before treatment were followed up until their first CAD event or 31 December 2010. Multivariable logistic regression models were used to analyze the correlation of LDL-C and/or ATT levels with the risk of developing CAD. RESULTS During the follow-up period, 21 of the 109 patients had a CAD event, diagnosed by coronary angiogram. Individuals in the highest tertile of LDL-C had a CAD risk 8.29-fold higher than those in the lowest tertile. Individuals in the highest tertile of the ATT group had a 7.82-fold higher CAD risk than those in the lowest tertile. Those who had either LDL-C ≥ 260 mg/dL or ATT ≥ 14.5 had a 23.94-fold higher CAD risk than those with LDL-C < 260 mg/dL and ATT <14.5 mm. CONCLUSIONS In heterozygous FH patients, LDL-C 260 mg/dL or higher and/or ATT 14.5 mm or thicker are useful markers for extracting patients at "very high" risk for CAD.

Abstract
Objective: Along with the increasing prevalence of obesity and related diseases, particularly atherosclerotic diseases, metabolic syndrome (MetS) is now a common and major public health issue in many countries around the world. Adiponectin, a protein secreted by the adipose tissue, has become recognized as a key player in the development of MetS. These days, not only MetS but also borderline metabolic/physiological abnormalities, such as impaired fasting glucose, high normal blood pressure and high normal plasma cholesterol, have been reported to be risk factors for atherosclerotic disease. Therefore, we undertook this study to determine the relationship between adiponectin and borderline metabolic/physiological abnormalities, as well as MetS. Design: A cross-sectional study performed from April 2007 to November 2009. Subjects: In 16 892 Japanese adults (10 008 men and 6884 women), we examined the relationship between the serum adiponectin concentration and borderline metabolic/physiological abnormalities or MetS by a questionnaire survey about medical treatment, body size measurement and measurement of laboratory parameters including the serum adiponectin concentration. Results: Adiponectin showed a significant negative correlation with the number of MetS components. In subjects without overt diabetes mellitus, hypertension or dyslipidemia, the adiponectin concentration also showed a significant negative correlation with the number of borderline metabolic abnormalities. Conclusion: The decrease of circulating adiponectin may start before the development of diabetes mellitus, hypertension, dyslipidemia or MetS. Adiponectin is an important biomarker for reflecting the adverse influence of visceral fat in persons with MetS, and also in these subclinical states.

Abstract
Adiponectin is one of the important molecules in the development of metabolic syndrome, and its concentration is decreased in obesity, type-2 diabetes, and cardiovascular disease. We aim to determine whether serum high-molecular weight (HMW) adiponectin, which is thought to represent the biological active form, was associated with a risk for the prevalence of prehypertension and hypertension. The cross-sectional study was carried out in 2002. A total of 614 men, aged 58 ± 14 (range, 20-89) years, and 779 women, aged 62 ± 12 (range, 21-88) years without medications for hypertension, diabetes, or dyslipidemia were recruited from a single community at the time of their annual health examination. In men, nonadjusted and age-adjusted mean serum HMW adiponectin were significantly lower in subjects with prehypertension and hypertension than those with normotension. In women, only nonadjusted values were higher in subjects with hypertension than those with normotension. Multiple linear regression analysis using systolic blood pressure (SBP) and diastolic blood pressure (DBP) as an objective variable, adjusted for risk factors as explanatory variables, showed that only in men, log serum HMW adiponectin were significantly and independently associated with SBP and DBP. In men, lower serum HMW adiponectin categories were positively associated with prehypertension and hypertension in an age-adjusted model, and hypertension in an age- and BMI-adjusted model. Serum HMW adiponectin concentrations were inversely associated with blood pressure (BP) in the general male population.

Abstract
PURPOSE To investigate the impact of cataract surgery and blood pressure changes induced by one week of sodium restriction on retinal vascular diameter. METHODS Fundus photographs of 200 patients were obtained before and one week after cataract surgery. For one week after admission, 100 patients received sodium restriction and 100 patients (ie, the control group) did not receive sodium restriction. The diameter of the retinal vessels and blood pressure were compared between the sodium restriction group and the control group. The vascular diameter was measured using an objective computer-based method. RESULTS Neither group had a significant change in the diameter of the retinal vessels after cataract surgery. Although there was no significant change in retinal arterial and venular diameter in the sodium restriction group, one-week sodium restriction significantly reduced mean blood pressure. However, multiple linear regression analyses indicated that an increase in retinal arteriolar diameter was significantly associated with diabetes, hyperlipidemia, and alcohol intake. CONCLUSION Cataract surgery and blood pressure reduction induced by one week of sodium restriction resulted in no significant change in retinal arteriolar diameter.

Abstract
IMPORTANCE OF THE FIELD Many clinical trials of pitavastatin have been done since its launch. New insights on pitavastatin from these trials are summarized and evaluated. AREAS COVERED IN THIS REVIEW The results of clinical studies using pitavastatin, from 2008 to 2009, the LIVES study, the JAPAN-ACS study, the CHIBA study, the PIAT study and Phase III clinical trials in the West are reviewed. WHAT THE READER WILL GAIN In the LIVES study, pitavastatin showed significant and continuous elevation of high-density lipoprotein cholesterol (HDL-C), estimated glomerular filtration rate (eGFR), as well as potential decrease in low-density lipoprotein cholesterol (LDL-C), in addition to long-term safety. Non-inferiority of pitavastatin against atorvastatin in the percentage change in plaque volume was proved in the JAPAN-ACS study. Also, comparable effects on LDL-C reduction rate of pitavastatin versus atorvastatin were confirmed in the CHIBA study and Phase III clinical trials in the West, and a greater increase in HDL-C was observed than with atorvastatin in the PIAT study. TAKE HOME MESSAGE Pitavastatin is a useful potent stain in raising HDL-C as well as in lowering of LDL-C, though a large-scale, clinical trial to confirm prevention of cardiovascular events is needed in the future.

Abstract
BACKGROUND There are few cross-sectional and longitudinal studies on identification of the age of onset of obesity. The purpose of the present study was therefore to investigate 30 years of cross-sectional and longitudinal changes in the prevalence of obesity from 1978 to 2007 in Japanese children and adolescents between 5 and 17 years of age, using population-based samples. METHODS Subject data were obtained from the Annual Reports of the School Health Survey published by the Ministry of Education, Culture, Sports, Science and Technology, Japan. Obesity was defined as a body mass index (BMI) at or above the 95th percentile for age and gender based on the reference years from 1979 to 1981 in Japan. The BMI was calculated as weight in kg/(height in m)(2). RESULTS Cross-sectional analysis of 5-, 8-, 11-, 14-, and 17-year-olds showed that the prevalence of obesity has gradually decreased since the early 2000s, with the highest prevalence in the late 1990s to early 2000s, except for in 17 year-old boys. Longitudinal studies showed that the critical periods for developing obesity were in late infancy (between 5 and 6 years of age) and in the high school period in boys, and mainly in late infancy in girls. CONCLUSIONS Intervention to prevent obesity should be focused on late infancy in both genders and male adolescents in Japan.

Abstract
AIM To clarify the relationship between the accumulation of cardiovascular risk factors and the 5-year decline in instrumental activity of daily living (IADL) among a cohort representative of the Japanese population aged 65 years and over. METHODS An IADL survey was performed by public health centers throughout Japan. Study subjects were elderly men and women living in districts under the jurisdiction of collaborating health centers. Subjects were invited to participate in the IADL survey assessed by the Tokyo Metropolitan Institute of Gerontology (TMIG) Index of Competence twice in 1995 and in 2000; 1222 participants were eligible for the analysis. The relationship between the number of cardiovascular risk factors, such as hypertension, hypercholesterolemia, hypertriglycemia, low serum high-density lipoprotein cholesterol, diabetes, obesity and smoking, at baseline and the 5-year difference in IADL scores was examined by linear regression analysis and logistic regression analysis. RESULTS Decrease in IADL scores was larger in those with cardiovascular risk factors than in those without. The multivariable odds ratio (OR) for decreased IADL after adding one CVD risk factor was 1.16 (95% confidence interval (CI), 1.04-1.29) after adjusting for age, sex, alcohol consumption and TMIG score at baseline. Among participants who were regarded as physically independent with respect to basic ADL in the baseline survey, the odds ratio was also similar and significant. CONCLUSION Preventive interventions directed against cardiovascular risk factors, especially against their accumulation, may contribute to maintaining IADL in the Japanese elderly.

Abstract
BACKGROUND Worldwide, the rate of aging is highest in Japan, especially the female population. To explore the trends for acute myocardial infarction (AMI) in Japan, the MIYAGI-AMI Registry Study has been conducted for 30 years since 1979, whereby all AMI patients in the Miyagi prefecture are prospectively registered. METHODS AND RESULTS In 1979-2008, 22,551 AMI patients (male/female 16,238/6,313) were registered from 43 hospitals. The age-adjusted incidence of AMI (/100,000persons/year) increased from 7.4 in 1979 to 27.0 in 2008 (P<0.001). Although control of coronary risk factors remained insufficient, the rates of ambulance use and primary percutaneous coronary intervention (PCI) have increased, and the overall in-hospital mortality (age-adjusted) has decreased from 20.0% in 1979 to 7.8% in 2008 (P<0.0001). However, the in-hospital mortality remains relatively higher in female than in male patients (12.2% vs 6.3% in 2008). Female patients were characterized by higher age and lower PCI rate. CONCLUSIONS The MIYAGI-AMI Registry Study demonstrates the steady trend of an increasing incidence, but decreasing mortality, for AMI in Japan over the past 30 years, although the female population still remains at higher risk for in-hospital death, despite improvements in the use of ambulances and primary PCI. (Circ J 2010; 74: 93 - 100).

Abstract
BACKGROUND Although many epidemiological studies have suggested that a decreased level of high-density lipoprotein-cholesterol (HDL-C) is a risk factor for heart disease; this relationship remains uncertain in relation to triglycerides (TG). This study examined the effects of serum TG and HDL-C on the incidence of ischemic heart disease (IHD) in Korean men. METHODS AND RESULTS A 14-year prospective cohort study was carried out with 29,171 Korean men who received insurance from the National Health Insurance Corporation and underwent a second screening for their cardiovascular risks. The main outcome measures were incidence of IHD. During 379,539 person-years of follow-up, 1,634 IHD (227 fatal IHD) events occurred. In the age-adjusted models, men in the lowest level of HDL-C (<30 mg/dl) showed a higher risk [hazard ratio (HR) 1.57; 95% confidence interval (CI) 1.26-1.95] when compared with men with the highest concentration (HDL-C > or =60 g/dl), defined as the reference group. When TG were included in the multivariate adjusted Cox model, the relationship of HDL-C with IHD was weakened but remained (HR 1.38; 95%CI 1.10-1.73). The results were similar for TG in the multivariate model including HDL-C. CONCLUSIONS These findings indicate that elevated TG and reduced HDL-C are independent risk factors for IHD risk in Korean men with cardiovascular risks.

Abstract
BACKGROUND The aims of this study were to clarify the risk factors for stroke, and to investigate the effect of low-density lipoprotein cholesterol (LDL-C) lowering with pravastatin on the risk of stroke, in Japanese mild-to-moderately hypercholesterolemic patients enrolled in the MEGA Study. METHODS Multivariate Cox proportional hazard model was used to determine the baseline risk factors for stroke. The proportion of treatment effect (PTE) explained by on-treatment LDL-C levels was estimated. RESULTS In 7832 patients at risk, a total of 99 strokes were observed during the 5-year follow-up period. Significant relationships were observed between stroke and traditional risk factors such as male sex, advanced age, low high-density lipoprotein cholesterol (HDL-C), high lipoprotein(a) (Lp[a]), hypertension, diabetes, obesity, and smoking. In the pravastatin group, hazard ratio (HR) for stroke adjusted by on-treatment lipid level was lower than the unadjusted value versus control (HR [95%CI], 0.48 [0.26-0.87] and 0.59 [0.38-0.92], respectively)--giving a negative PTE of -38.6% and suggesting that the risk reduction could not be explained by LDL-C lowering alone. CONCLUSIONS Male sex, aging, hypertension, diabetes, low HDL-C, high Lp(a), obesity, and smoking were determined as risk factors for stroke in Japanese patients with hypercholesterolemia, and the observed risk reduction could not be explained by pravastatin's LDL-C-lowering effect alone, suggesting pleiotropic effects.
