    ABSTRACT: We aimed to evaluate the hypotensive effect and the time to attain the maximal antihypertensive effect (stabilization time) of 8 mg candesartan/6.25 mg hydrochlorothiazide (HCTZ) combination therapy (combination regimen) and therapy with an increased candesartan dose (12 mg; maximum dose regimen) using home blood pressure (BP) measurements. A prospective, multicenter, open-label, randomized, comparative trial was conducted. Essential hypertensive patients who failed to achieve adequate BP control (systolic BP (SBP) ⩽135 mm Hg) on 8 mg candesartan alone were randomized to two groups: the combination regimen (n=103) and the maximum dose regimen (n=103). Home morning SBP reduction at 8 weeks after randomization was 11.4±1.3 mm Hg in the combination regimen and 7.8±1.2 mm Hg in the maximum dose regimen. The combination regimen provided additional reduction of 4.0 mm Hg (95% confidence interval (CI): 0.8-7.2 mm Hg, P=0.01) in home morning SBP over the maximum dose regimen at 8 weeks after randomization. The maximal antihypertensive effect and stabilization time for home SBP were 9.4 mm Hg and 37.1 days (P<0.0001), respectively, with the combination regimen. The maximum dose regimen decreased home SBP with a very gentle slope, and estimated maximal effect and estimated stabilization time were not significant (P>0.2). The rate of achieving target BP (home morning SBP <135 mm Hg) was significantly higher with the combination regimen than with the maximum dose regimen (52.4 vs. 30.1%, P=0.002). In conclusion, changing from 8 mg candesartan to combination therapy was more effective in reducing home SBP and achieving goal BP more rapidly than increasing the candesartan dose.Hypertension Research advance online publication, 4 June 2015; doi:10.1038/hr.2015.64.

    ABSTRACT: The association between obesity and all-cause mortality is controversial and may differ according to subjects' characteristics. Blood pressure variability (BPV) may be increased in obese individuals and thus impair prognosis. The purpose of this study was to evaluate whether the relationship between obesity and mortality is influenced by short-term ambulatory BPV. The analysis was performed in 8724 participants (54% men) aged 51 ± 15 years enrolled in 8 prospective studies in Australia, Italy, Japan, and U.S.A. The predictive power of obesity (BMI >=30 kg/m2) for mortality was evaluated from multivariable Cox models in the subjects stratified by high or low nocturnal BPV (above or below the median). Obese participants (N = 1286) had higher age-and-sex adjusted systolic and diastolic BPV than the non-obese participants (p = 0.002/<0.001). Obese subjects with high systolic or diastolic BPV had higher nocturnal heart rate (p = 0.01/<0.001) than obese subjects with low BPV and were more frequently diabetic (p<0.001) and heavy alcohol drinkers (p < 0.001). During a median follow-up of 6.4 years there were 361 deaths, 4.7% in the obese and 4.0% in the non-obese individuals (P = NS). However, the risk of mortality among the obese subjects greatly differed according to BPV level. In Cox models including age, sex, mean ambulatory BP, smoking, alcohol use, diabetes, cholesterol, creatinine, and nocturnal heart rate, the obese group with high systolic BPV had a doubled risk of mortality compared to the non-obese group (HR,2.0, 95%CI,1.4-2.9, p < 0.001), whereas the risk was not increased in the obese group with low BPV (P = 0.81). Similar results were found for diastolic BPV, with a HR of 1.7 (1.2-2.5, p = 0.002) in the high BPV group and no association at all with mortality (p = 0.87) in the low BPV group. Inclusion of night-time BP dipping in the regressions did not change the strength of the associations. These data show that high nocturnal BPV greatly increases the risk of mortality related to obesity. High BPV is accompanied by increased heart rate and may reflect the influence of transient BP elevations related to sleep apnea and/or baroreflex dysfunction.

    ABSTRACT: Women who had hypertensive disorders in pregnancy have an increased risk of cardiovascular diseases in later life. No studies, however, have investigated whether maternal hypertensive disorders in pregnancy affect self-measured blood pressure at home (HBP) in mothers and their children. We evaluated the association between maternal hypertension during pregnancy and HBP based on the prospective Tohoku Study of Child Development birth cohort study, which was performed in two areas in Japan. We included children in a singleton birth at term (36-42 weeks of gestation) with a birth weight of >2400 g. We collected prenatal care data from the medical charts. Because only two mothers experienced preeclampsia, we defined gestational hypertension (GH) as a hypertensive disorder in pregnancy. Seven years after birth, mothers and their children measured their HBP in the morning for 2 weeks. Of 813 eligible mothers, 28 (3.4%) experienced GH, and those were of a similar age compared with 785 non-GH mothers (37.3 vs. 38.0 years; P=0.41). Women with GH had higher body mass index (BMI) (23.8 vs. 21.4 kg m(-)(2); P=0.01) and elevated HBP (120.3/76.8 vs. 110.4/68.6 mm Hg; P<0.0002) 7 years after delivery. However, HBP was similar in children with and without GH mothers (93.5/55.9 vs. 94.1/56.1 mm Hg, P>0.38). These results were confirmatory in case-control (1:2) analyses with matching by maternal age, maternal BMI before pregnancy, survey area and parity. In conclusion, maternal GH did not affect HBP in offspring but strongly affected maternal HBP even 7 years after birth.Hypertension Research advance online publication, 14 May 2015; doi:10.1038/hr.2015.63.

    ABSTRACT: The objective of this study was to investigate physicians' awareness and use of the Japanese Society of Hypertension (JSH) Guidelines for the Management of Hypertension (JSH2004 and JSH2009), and determine what changes need to be implemented in the future. A questionnaire was used to survey physicians' awareness and their use of JSH2004 and JSH2009. Physicians attending educational seminars on hypertension that were held during the months after the publication of JSH2009 (January-April 2009) were asked to participate in the survey. Of the 5795 respondents, 88% were aware of the JSH2009 publication. Furthermore, physicians were also aware of JSH2004, with about 90% using JSH2004 in their practice. A hypertension blood pressure (BP) reference value of 140/90 mm Hg was used by 55% in office BP, whereas 31% used 135/85 mm Hg for home BP. Target BP levels used by physicians were 130/80 mm Hg for patients with diabetes or kidney disease (52%) and for elderly patients with diabetes or kidney disease (45%), whereas 140/90 mm Hg was used for elderly patients with low cardiovascular disease risk (44%) and for patients with chronic-phase stroke (27%). Answers to the questionnaire varied among physicians according to sex, age, workplace and specialty. The majority of the participating Japanese physicians were familiar with both JSH2004 and JSH2009, with many following the guidelines in their practice. However, some physicians use different reference values for hypertension and target BP levels. Physicians' adherence to and use of the guidelines should be regularly examined and promoted.Hypertension Research advance online publication, 2 April 2015; doi:10.1038/hr.2015.21.

    ABSTRACT: In addition to day-to-day variability in blood pressure (BP) or heart rate (HR), N-terminal pro B-type natriuretic peptide (NT-proBNP) has been reported to be a predictor of cardiovascular disease. Here, we tested the hypothesis that day-to-day BP or HR variability calculated as the intraindividual standard deviation (SD) of home BP or HR is associated with elevated NT-proBNP in a cross-sectional study. Among 664 participants (mean age, 61.9 years; female, 70.5%) from a general Japanese population without a history of heart disease, 86 (13.0%) had NT-proBNP at least 125 pg/ml. Each 1 SD increase in the SD of home systolic BP (SBP) [odds ratio (OR), 1.82; P < .0001) and in the SD of home HR (OR, 1.44; P = 0.008) were significantly associated with the prevalence of NT-proBNP at least 125 pg/ml after adjustment for possible confounding factors including home SBP and HR. Among the four groups defined by the median SD of home SBP and of home HR, the group with higher SDs in home SBP (≥8.0 mmHg) and HR (≥5.0 bpm) had the greatest OR for the prevalence of NT-proBNP at least 125 pg/ml (OR, 4.80; P = 0007 vs. a reference group with lower SDs of home SBP and HR). These results suggest that day-to-day variability in BP and HR may be associated with target-organ damage or complications, which can lead to an elevated NT-proBNP level. An elevated NT-proBNP level may be involved in the prognostic significance of day-to-day variability in BP or HR.

    ABSTRACT: The association of high-density lipoprotein particle (HDL-P) with atherosclerosis may be stronger than that of HDL-cholesterol (HDL-C) and independent of conventional cardiovascular risk factors. Whether associations persist in populations at low risk of coronary heart disease (CHD) remains unclear. This study examines the associations of HDL-P and HDL-C with carotid intima-media thickness (cIMT) and plaque counts among Japanese men, who characteristically have higher HDL-C levels and a lower CHD burden than those in men of Western populations. We cross-sectionally examined a community-based sample of 870 Japanese men aged 40-79 years, free of known clinical cardiovascular disease (CVD) and not on lipid-lowering medication. Participants were randomly selected among Japanese living in Kusatsu City in Shiga, Japan. Both HDL-P and HDL-C were inversely and independently associated with cIMT in models adjusted for conventional CHD risk factors, including low-density lipoprotein cholesterol (LDL-C) and diabetes. HDL-P maintained an association with cIMT after further adjustment for HDL-C (P < 0.01), whereas the association of HDL-C with cIMT was noticeably absent after inclusion of HDL-P in the model. In plaque counts of the carotid arteries, HDL-P was significantly associated with a reduction in plaque count, whereas HDL-C was not. HDL-P, in comparison to HDL-C, is more strongly associated with measures of carotid atherosclerosis in a cross-sectional study of Japanese men. Findings demonstrate that, HDL-P is a strong correlate of subclinical atherosclerosis even in a population at low risk for CHD. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    ABSTRACT: No large-scale, longitudinal studies have examined the combined effects of blood pressure (BP) and total cholesterol levels on long-term risks for subtypes of cardiovascular death in an Asian population. To investigate these relationships, a meta-analysis of individual participant data, which included 73 916 Japanese subjects (age, 57.7 years; men, 41.1%) from 11 cohorts, was conducted. During a mean follow-up of 15.0 years, deaths from coronary heart disease, ischemic stroke, and intraparenchymal hemorrhage occurred in 770, 724, and 345 cases, respectively. Cohort-stratified Cox proportional hazard models were used. After stratifying the participants by 4 systolic BP ×4 total cholesterol categories, the group with systolic BP ≥160 mm Hg with total cholesterol ≥5.7 mmol/L had the greatest risk for coronary heart disease death (adjusted hazard ratio, 4.39; P<0.0001 versus group with systolic BP <120 mm Hg and total cholesterol <4.7 mmol/L). The adjusted hazard ratios of systolic BP (per 20 mm Hg) increased with increases in total cholesterol categories (hazard ratio, 1.52; P<0.0001 in group with total cholesterol ≥5.7 mmol/L). Similarly, the adjusted hazard ratios of total cholesterol increased with increases in systolic BP categories (P for interaction ≤0.04). Systolic BP was positively associated with ischemic stroke and intraparenchymal hemorrhage death, and total cholesterol was inversely associated with intraparenchymal hemorrhage, but no significant interactions between BP and total cholesterol were observed for stroke. High BP and high total cholesterol can synergistically increase the risk for coronary heart disease death but not for stroke in the Asian population. © 2015 American Heart Association, Inc.

    ABSTRACT: Background/Objectives:There have been few studies on the association of fruit and vegetable (FV) intake with cardiovascular disease (CVD) risk in Asian populations where both dietary habits and disease structure are different from western countries. No study in Asia has found its significant association with stroke. We examined associations of FV intake with mortality risk from total CVD, stroke and coronary heart diseases (CHDs) in a representative Japanese sample.Methods:A total of 9112 participants aged from 24-year follow-up data in the NIPPON DATA80, of which baseline data were obtained in the National Nutrition Survey Japan in 1980, were studied. Dietary data were obtained from 3-day weighing dietary records. Participants were divided into sex-specific quartiles of energy adjusted intake of FV. Multivariate-adjusted hazard ratios (HRs) were calculated between strata of the total of FV intake, fruit intake and vegetable intake. The adjustment included age, sex, smoking, drinking habit and energy adjusted intakes of sodium and some other food groups.Results:Participants with higher FV intake were older, ate more fish, milk and dairy products and soybeans and legumes and ate less meat. Multivariate-adjusted HR (95% confidence interval; P; P for trend) for the highest versus the lowest quartile of the total of FV intake was 0.74 (0.61-0.91; 0.004; 0.003) for total CVD, 0.80 (0.59-1.09; 0.105; 0.036) for stroke and 0.57 (0.37-0.87; 0.010; 0.109) for CHD.Conclusions:The results showed that higher total intake of FVs was significantly associated with reduced risk of CVD mortality in Japan.European Journal of Clinical Nutrition advance online publication, 14 January 2015; doi:10.1038/ejcn.2014.276.

    ABSTRACT: Rapid increases in life expectancy have led to concurrent increases in the number of elderly people living alone or those forced to change living situations. Previous studies have found that poor dietary intake was common in elderly people living alone. However, there have been few studies about the dietary intake in elderly people living in other situations, particularly those living with family other than a spouse (nonspouse family), which is common in Japan. To examine the differences in dietary intake by different living situations in elderly Japanese people. We analyzed the data of 1542 healthy residents in the town of Ohasama aged 60 years and over who had completed self-administered questionnaires. The dietary intake was measured using a validated 141-item food frequency questionnaire. Multiple regression models with robust (White-corrected) standard errors were individually fitted for nutrients and foods by living situation. In men, although the presence of other family was correlated with significantly lower intake of protein-related foods, e.g., legumes, fish and shellfish, and dairy products, these declines were more serious in men living with nonspouse family. Conversely, in men living alone the intake of fruits and vegetables was significantly lower. In women, lower intakes of fruit and protein-related foods were significantly more common in participants living with nonspouse family than those living with only a spouse. These findings revealed that elderly people living alone as well as those living with family other than a spouse had poor dietary intake, suggesting that strategies to improve food choices and skills for food preparation could promote of healthy eating in elderly Japanese people.

    ABSTRACT: On March 11, 2011, the Great East Japan Earthquake hit northeast Japan. Previous letter on Hypertension by Sato et al reported that 11.6/3.9mmHg for systolic/diastolic blood pressure (BP) and 4.7bpm for heart rate (HR) elevations were observed by home BP measurement among hypertensive outpatients aged 68.1±8.8 years. In this study we observed home BP change before and after the earthquake among pregnant women. We used database from the BOSHI study which participated pregnant women from October 2006 to September 2011 at a maternity hospital In Miyagi Prefecture, Japan. The participants were asked to measure their own BPs every morning at home while they were pregnant. A linear mixed model was used for analysis of the BP course throughout pregnancy. Total 1137 pregnant woman was included into the analysis. Of those, 210 pregnant women were participated before the earthquake and gave birth after the earthquake. Of those, 133 women measured their BP in March 2011. The average number of home BP measurements was 13.8 in March 2011. Home BP and HR which are not measured in March 2011 were 105.9(105.4-106.4)/63.2(62.8-63.6)mmHg and 74.3(73.9-74.7)bpm, respectively. Home BP and HR were 105.0(103.5-106.4)/64.1(62.8-65.3)mmHg, 73.8(71.8-81.8)bpm in the morning at March 11, 2011 (just before the earthquake), and 110.7(104.8-116.6)/63.6(58.4-68.8)mmHg, 76.3(70.2-82.5)bpm in the morning at March 12, 2011 (just after the earthquake), respectively. Home BP was immediately elevated just after the earthquake and gradually decreased over a month as we previously reported among hypertensive patients. Because we only analyzed BP who could keep their equipment, the BP change just after the earthquake might be underestimated. H.

    ABSTRACT: Background Up-to-date evidence on levels and trends for age-sex-specific all-cause and cause-specific mortality is essential for the formation of global, regional, and national health policies. In the Global Burden of Disease Study 2013 (GBD 2013) we estimated yearly deaths for 188 countries between 1990, and 2013. We used the results to assess whether there is epidemiological convergence across countries. Methods We estimated age-sex-specific all-cause mortality using the GBD 2010 methods with some refinements to improve accuracy applied to an updated database of vital registration, survey, and census data. We generally estimated cause of death as in the GBD 2010. Key improvements included the addition of more recent vital registration data for 72 countries, an updated verbal autopsy literature review, two new and detailed data systems for China, and more detail for Mexico, UK, Turkey, and Russia. We improved statistical models for garbage code redistribution. We used six different modelling strategies across the 240 causes; cause of death ensemble modelling (CODEm) was the dominant strategy for causes with sufficient information. Trends for Alzheimer's disease and other dementias were informed by meta-regression of prevalence studies. For pathogen-specific causes of diarrhoea and lower respiratory infections we used a counterfactual approach. We computed two measures of convergence (inequality) across countries: the average relative difference across all pairs of countries (Gini coefficient) and the average absolute difference across countries. To summarise broad findings, we used multiple decrement life-tables to decompose probabilities of death from birth to exact age 15 years, from exact age 15 years to exact age 50 years, and from exact age 50 years to exact age 75 years, and life expectancy at birth into major causes. For all quantities reported, we computed 95% uncertainty intervals (UIs). We constrained cause-specific fractions within each age-sex-country-year group to sum to all-cause mortality based on draws from the uncertainty distributions. Findings Global life expectancy for both sexes increased from 65·3 years (UI 65·0–65·6) in 1990, to 71·5 years (UI 71·0–71·9) in 2013, while the number of deaths increased from 47·5 million (UI 46·8–48·2) to 54·9 million (UI 53·6–56·3) over the same interval. Global progress masked variation by age and sex: for children, average absolute differences between countries decreased but relative differences increased. For women aged 25–39 years and older than 75 years and for men aged 20–49 years and 65 years and older, both absolute and relative differences increased. Decomposition of global and regional life expectancy showed the prominent role of reductions in age-standardised death rates for cardiovascular diseases and cancers in high-income regions, and reductions in child deaths from diarrhoea, lower respiratory infections, and neonatal causes in low-income regions. HIV/AIDS reduced life expectancy in southern sub-Saharan Africa. For most communicable causes of death both numbers of deaths and age-standardised death rates fell whereas for most non-communicable causes, demographic shifts have increased numbers of deaths but decreased age-standardised death rates. Global deaths from injury increased by 10·7%, from 4·3 million deaths in 1990 to 4·8 million in 2013; but age-standardised rates declined over the same period by 21%. For some causes of more than 100 000 deaths per year in 2013, age-standardised death rates increased between 1990 and 2013, including HIV/AIDS, pancreatic cancer, atrial fibrillation and flutter, drug use disorders, diabetes, chronic kidney disease, and sickle-cell anaemias. Diarrhoeal diseases, lower respiratory infections, neonatal causes, and malaria are still in the top five causes of death in children younger than 5 years. The most important pathogens are rotavirus for diarrhoea and pneumococcus for lower respiratory infections. Country-specific probabilities of death over three phases of life were substantially varied between and within regions. Interpretation For most countries, the general pattern of reductions in age-sex specific mortality has been associated with a progressive shift towards a larger share of the remaining deaths caused by non-communicable disease and injuries. Assessing epidemiological convergence across countries depends on whether an absolute or relative measure of inequality is used. Nevertheless, age-standardised death rates for seven substantial causes are increasing, suggesting the potential for reversals in some countries. Important gaps exist in the empirical data for cause of death estimates for some countries; for example, no national data for India are available for the past decade.

    ABSTRACT: Aim: To examine whether the inflammatory markers C-reactive protein (CRP) and fibrinogen are associated with biomarkers of atherosclerosis [carotid intima-media thickness (IMT) and coronary artery calcification (CAC)] in the general male population, including Asians.Methods: Population-based samples of 310 Japanese, 293 Japanese-American and 297 white men 40-49 years of age without clinical cardiovascular disease underwent measurement of IMT, CAC and the CRP and fibrinogen levels as well as other conventional risk factors using standardized methods. Statistical associations between the variables were evaluated using multiple linear or logistic regression models.Results: The Japanese group had significantly lower levels of inflammatory markers and subclinical atherosclerosis than the Japanese-American and white groups (P-values all <0.001). The mean level of CRP was 0.66 vs. 1.11 and 1.47 mg/L, while that of fibrinogen was 255.0 vs. 313.0 and 291.5 mg/dl, respectively. In addition, the mean carotid IMT was 0.61 vs. 0.73 and 0.68 mm, while the mean prevalence of CAC was 11.6% vs. 32.1% and 26.3%, respectively. Body mass index (BMI) showed significant positive associations with both the CRP and fibrinogen levels. Although CRP showed a significant positive association with IMT in the Japanese men, this association became non-significant following adjustment for traditional risk factors or BMI. In all three populations, CRP was not found to be significantly associated with the prevalence of CAC. Similarly, fibrinogen did not exhibit a significant association with either IMT or the prevalence of CAC.Conclusions: The associations between inflammatory markers and subclinical atherosclerosis may merely reflect the strong associations between BMI and the levels of inflammatory markers and incidence of subclinical atherosclerosis in both Eastern and Western populations.
