Background: Evidence from prospective cohort studies regarding the relationship between working hours and risk of cardiovascular disease is limited Methods and Results: The Japan Public Health Center-Based Prospective Study Cohort II involved 15,277 men aged 40–59 years at the baseline survey in 1993. Respondents were followed up until 2012. During the median 20 years of follow up (257,229 person-years), we observed 212 cases of acute myocardial infarction and 745 stroke events. Cox proportional hazards models adjusted for sociodemographic factors, cardiovascular risk factors, and occupation showed that multivariable-adjusted hazard ratios (HRs) associated with overtime work of ≥11h/day were: 1.63 (95% confidence interval [CI] 1.01–2.63) for acute myocardial infarction and 0.83 (95% CI 0.60–1.13) for total stroke, as compared with the reference group (working 7 to <9 h/day). In the multivariable model, increased risk of acute myocardial infarction associated with overtime work of ≥11 h/day was more evident among salaried employees (HR 2.11, 95% CI 1.03–4.35) and men aged 50–59 years (HR 2.60, 95% CI 1.42–4.77). Conclusions: Among middle-aged Japanese men, working overtime is associated with a higher risk of acute myocardial infarction.

Background: Coffee, which contains various bioactive compounds, is one of the most popular beverages. Further accumulation of evidence is needed, however, to confirm whether coffee consumption would be effective in preventing cardiovascular disease in the general Japanese population. Methods and Results: We evaluated the association between coffee consumption frequency (never, sometimes, 1–2 cups/day, 3–4 cups/day and ≥5 cups/day) and mortality from all causes, heart disease, and cerebrovascular disease, in 39,685 men and 43,124 women aged 40–79 years at baseline, in a 3-prefecture cohort study. The coffee consumption frequency was assessed on questionnaire. Cox proportional hazards regression modeling was used to assess the association between coffee consumption frequency and all-cause and cardiovascular disease mortality with adjustment for potential confounders. During 411,341 and 472,433 person-years in men and women, respectively, a total of 7,955 men and 5,725 women died. Coffee consumption frequency was inversely associated with all-cause mortality in both genders (P for trend<0.001). In addition, the risks of mortality from cerebrovascular disease in men (P for trend<0.001), and heart disease in women (P for trend=0.031) were inversely associated with coffee consumption. Conclusions: In this Japanese population, coffee drinking has a preventive effect on all-cause and on cardiovascular mortality in men and/or women.

Background:The association between serum uric acid (UA) levels and atrial fibrillation (AF) in the general population in Japan is not well known.Methods and Results:In total, 285,882 consecutive subjects (men, 130,897; women, 154,985; age, 58±15 years) not receiving treatment for hyperuricemia who underwent health checkups were enrolled. Subjects were stratified into deciles according to age, body mass index, estimated glomerular filtration rate, systolic blood pressure, and UA level. AF prevalence was calculated for each decile. The odds ratio that defined the decile with the lowest AF prevalence as reference was calculated in each sex. In men, the mean UA was 6.0±1.4 mg/dl; AF prevalence was 1.8% and was lowest in the decile with UA 4.4–4.9 mg/dl. Deciles with both high and low UA (5.4–5.6 mg/dl to >7.8 mg/dl and <4.3 mg/dl) were associated with significantly higher AF prevalence. In women, the mean UA was 4.5±1.1 mg/dl; AF prevalence was 0.7% and was lowest in the decile with UA 3.6–3.8 mg/dl. Deciles with highest UA (5.0–5.2 mg/dl to >5.9 mg/dl) were associated with significantly higher AF prevalence. The analysis adjusted for other clinical covariates demonstrated an independent association between UA and AF in both sexes.Conclusions:In a representative Japanese general population, UA level was significantly associated with AF, independently of other cardiovascular risk factors.

Chronic kidney disease (CKD) is characterized by high cardiovascular morbidity/mortality, which is linked in part to vascular calcification (VC) and endothelial dysfunction (ED). Hyperphosphatemia, a feature of CKD, is a well-known inducer of VC in preclinical models and is associated with poor outcomes in epidemiological studies. However, it remains to be seen whether lowering phosphate levels in CKD patients reduces VC and the morbidity/mortality rate. Furthermore, it is now clear from preclinical and clinical studies that phosphate is involved in ED. The present article reviews the direct and indirect mechanisms (eg, via fibroblast growth factor 23 and/or parathyroid hormone) by which hyperphosphatemia influence the onset of VC and ED in CKD.

Background: The effect of smoking on mortality in working-age adults remains unclear. Accordingly, we compared the effects of cigarette smoking and smoking cessation on total and cause-specific mortality in a Japanese working population. Methods and Results: This study included 79,114 Japanese workers aged 20–85 years who participated in the Japan Epidemiology Collaboration on Occupational Health Study. Deaths and causes of death were identified from death certificates, sick leave documents, family confirmation, and other sources. Hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated via Cox proportional hazards regression. During a maximum 6-year follow-up, there were 252 deaths in total. Multivariable-adjusted HRs (95% CIs) for total mortality, cardiovascular disease (CVD) mortality, and tobacco-related cancer mortality were 1.49 (1.10–2.01), 1.79 (0.99–3.24), and 1.80 (1.02–3.19), respectively, in current vs. never smokers. Among current smokers, the risks of total, tobacco-related cancer, and CVD mortality increased with increasing cigarette consumption (Ptrend<0.05 for all). Compared with never smokers, former smokers who quit <5 and ≥5 years before baseline had HRs (95% CIs) for total mortality of 1.80 (1.00–3.25) and 1.02 (0.57–1.82), respectively. Conclusions: In this cohort of workers, cigarette smoking was associated with increased risk of death from all and specific causes (including CVD and tobacco-related cancer), although these risks diminished 5 years after smoking cessation.

Cardiovascular disease (CVD) is the leading cause of mortality worldwide, causing an estimated 18 million deaths annually. Much of the burden of CVD resides in lower- and middle-income countries, particularly those Asian countries comprising the Western Pacific Region. Epidemiological studies have convincingly shown that up to 90% of all CVD can be explained by a small number of modifiable risk factors, including blood pressure, smoking, diabetes, total cholesterol and excess body weight. However, the relationship between these risk factors and coronary artery disease and stroke often differ by age and sex, and yet these differences are often overlooked in burden of disease estimations. As such, that can result in either an over- or under-estimation of the disease burden in specific population subgroups, which may affect resource allocation of healthcare. In this review, we derive the most reliable and previously unpublished estimates of the age- and sex-specific burden of vascular disease attributable to the aforementioned risk factors for 10 of the most populous Asian countries in the Western Pacific Region. Understanding how the burden of vascular disease is distributed within and between populations is crucial for developing appropriate health policies and effective treatment strategies, particularly in resource-poor settings.

Background:An atrial fibrillation (AF) risk score for a non-Western general population has not been established.Methods and Results:A total of 6,898 participants (30–79 years old) initially free of AF have been prospectively followed for incident AF since 1989. AF was diagnosed when AF or atrial flutter was present on ECG at a biannual health examination; was indicated as a current illness; or was in the medical records during follow-up. Cox proportional hazard ratios were analyzed after adjusting for cardiovascular risk factors at baseline. During the 95,180 person-years of follow-up, 311 incident AF events occurred. We developed a scoring system for each risk factor as follows: 0/−5, 3/0, 7/5, and 9/9 points for men/women in their 30 s–40 s, 50 s, 60 s, and 70 s, respectively; 2 points for systolic hypertension, overweight, excessive drinking, or coronary artery disease; 1 point for current smoking; −1 point for moderate non-high-density lipoprotein-cholesterol; 4 points for arrhythmia; and 8, 6, and 2 points for subjects with cardiac murmur in their 30 s–40 s, 50 s, and 60 s, respectively (C-statistic 0.749; 95% confidence interval, 0.724−0.774). Individuals with score ≤2, 10–11, or ≥16 points had, respectively, ≤1%, 9%, and 27% observed probability of developing AF in 10 years.Conclusions:We developed a 10-year risk score for incident AF using traditional risk factors that are easily obtained in routine outpatient clinics/health examinations without ECG.

Background:The prognostic impact of atrial fibrillation (AF) among patients at high risk for heart failure (HF) remains unclear. In addition, there is no risk estimation model for AF development in these patients.Methods and Results:The present study included 5,382 consecutive patients at high risk of HF enrolled in the CHART-2 Study (n=10,219). At enrollment, 1,217 (22.6%) had AF, and were characterized, as compared with non-AF patients, by higher age, lower estimated glomerular filtration rate, higher B-type natriuretic peptide (BNP) level and lower left ventricular ejection fraction. A total of 116 non-AF patients (2.8%) newly developed AF (new AF) during the median 3.1-year follow-up. AF at enrollment was associated with worse prognosis for both all-cause death and HF hospitalization (adjusted hazard ratio (aHR) 1.31, P=0.027 and aHR 1.74, P=0.001, for all-cause death and HF hospitalization, respectively) and new AF was associated with HF hospitalization (aHR 4.54, P<0.001). We developed a risk score with higher age, smoking, pulse pressure, lower eGFR, higher BNP, aortic valvular regurgitation, LV hypertrophy, and left atrial and ventricular dilatation on echocardiography, which effectively stratified the risk of AF development with excellent accuracy (AUC 0.76).Conclusions:These results indicated that AF is associated with worse prognosis in patients at high risk of HF, and our new risk score may be useful to identify patients at high risk for AF onset.

Atrial fibrillation (AF) is the most common cardiac rhythm disorder and a major risk factor for stroke. For more than 60 years, warfarin has been the only approved anticoagulant for prevention of stroke in patients with AF. Although highly effective, it has many limitations that make its use difficult. Therefore, several novel anticoagulants are under development to overcome the limitations of warfarin, and some of these have entered phase III clinical trials. Dabigatran is an oral, reversible direct thrombin inhibitor approved in Europe and in several other countries for the prevention of venous thromboembolism after elective knee and hip replacement surgery. It has also been approved in the United States and Japan for the prevention of stroke and systemic embolism in patients with nonvalvular AF. In this review, the mechanism of action and pharmacological properties of new anticoagulants are described in detail, and the correct use of dabigatran in clinical practice is discussed.

Background: We systematically reviewed the available literature on limb dysfunction after transradial access (TRA) or transfemoral access (TFA) cardiac catheterization. Methods and Results: MEDLINE and EMBASE were searched for studies evaluating any transradial or transfemoral procedures and limb function outcomes. Data were extracted and results were narratively synthesized with similar treatment arms. The TRA group included 15 studies with 3,616 participants and of these 3 reported nerve damage with a combined incidence of 0.16% and 4 reported sensory loss, tingling and numbness with a pooled incidence of 1.61%. Pain after TRA was the most common form of limb dysfunction (7.77%) reported in 3 studies. The incidence of hand dysfunction defined as disability, grip strength change, power loss or neuropathy was low at 0.49%. Although radial artery occlusion (RAO) was not a primary endpoint for this review, it was observed in 3.57% of the participants in a total of 8 studies included. The TFA group included 4 studies with 15,903,894 participants; the rates of peripheral neuropathy were 0.004%, sensory neuropathy caused by local groin injury and retroperitoneal hematomas were 0.04% and 0.17%, respectively, and motor deficit caused by femoral and obturator nerve damage was 0.13%. Conclusions: Limb dysfunction post cardiac catheterization is rare, but patients may have nonspecific sensory and motor complaints that resolve over a period of time.

Background:This study determined the current status of the incidence, management, and prognosis of stroke in Japan using a population-based stroke registry.Methods and Results:Shiga Stroke Registry is an ongoing population-based registry that covers approximately 1.4 million residents of Shiga Prefecture. Cases of acute stroke were identified using standard definitions through surveillance of both all acute-care hospitals with neurology/neurosurgery facilities and death certificates in 2011. A total of 2,956 stroke cases and 2,176 first-ever stroke cases were identified. The age- and sex-adjusted incidence rate for first-ever stroke using the 2013 European Standard Population as standard was per 100,000 person-years: 91.3 for ischemic stroke, 36.4 for intracerebral hemorrhage, and 13.7 for subarachnoid hemorrhage. It was estimated that approximately 220,000 new strokes occurred in 2011 in Japan. Among the 2,956 cases, most stroke patients underwent neuroimaging, 268 received surgical or endovascular treatment, and 2,158 had rehabilitation therapy; 78 patients received intravenous thrombolysis. A total of 1,846 stroke patients had died or were dependent at hospital discharge, and 390 died within 28 days of onset.Conclusions:Incidence rates of stroke by subtypes were clarified and the total number of new strokes in Japan was estimated. More than half of stroke patients die or become dependent after a stroke. This study re-emphasized the importance of public health measures in reducing the burden of stroke in Japan.

Background:The quality of cardiopulmonary resuscitation (CPR) has been recently shown to affect clinical outcome. The Resuscitation Outcomes Consortium (ROC) Prehospital Resuscitation Impedance Valve and Early Versus Delayed Analysis (PRIMED) trial showed no differences in outcomes with an active vs. sham impedance threshold device (ITD), a CPR adjunct that enhances circulation. It was hypothesized the active ITD would improve survival with favorable neurological outcomes in witnessed out-of-hospital cardiac arrest patients when used with high-quality CPR.Methods and Results:Using the publicly accessible ROC PRIMED database, a post-hoc analysis was performed on all witnessed subjects with both compression rate and depth data (n=1,808) who received CPR within the study protocol definition of adequate CPR quality (compression rate 80–120/min and depth 4–6 cm; n=929). Demographics were similar between sham and active ITD groups. In witnessed subjects who received quality CPR, survival with favorable neurological function was 11.9% for the active ITD subjects (56/470) vs. 7.4% for the sham (34/459) (odds ratio 1.69 [95% confidence interval 1.08, 2.64]). There were no statistically significant differences for this primary outcome when CPR was performed outside the boundaries of the definition of adequate CPR quality. Multivariable models did not change these associations.Conclusions:An active ITD combined with adequate-quality conventional CPR has the potential to significantly improve survival after witnessed cardiac arrest.

Background:Large earthquakes have been associated with cardiovascular disease (CVD) mortality. In Japan, the 1995 Great Hanshin-Awaji (H-A) Earthquake was an urban-underground-type earthquake, whereas the 2011 Great East Japan (GEJ) Earthquake was an ocean-trench type. In the present study, we examined how these different earthquake types affected CVD mortality.Methods and Results:We examined death certificate data from 2008 to 2012 for 131 municipalities in Iwate, Miyagi, and Fukushima prefectures (n=320,348) and from 1992 to 1996 for 220 municipalities in Hyogo, Osaka, and Kyoto prefectures (n=592,670). A Poisson regression model showed significant increases in the monthly numbers of acute myocardial infarction (AMI)-related deaths (incident rate ratio [IRR] GEJ=1.34, P=0.001; IRR of H-A=1.57, P<0.001) and stroke-related deaths (IRR of GEJ=1.42, P<0.001; IRR of H-A=1.33, P<0.001) after the earthquakes. Two months after the earthquakes, AMI deaths remained significant only for H-A (IRR=1.13, P=0.029). When analyzing the standardized mortality ratio (SMR) after the earthquakes using the Cochran-Armitage trend test, seismic intensity was significantly associated with AMI mortality for 2 weeks after both the GEJ (P for trend=0.089) and H-A earthquakes (P for trend=0.005).Conclusions:Following the GEJ and H-A earthquakes, there was a sharp increase in CVD mortality. The effect of the disaster was sustained for months after the H-A earthquake, but was diminished after the GEJ Earthquake. (Circ J 2015; 79: 1000–1008)

The present study was designed to establish adequate criteria for categorizing `obesity disease' in Japan in relation to obesity-related complications. The subjects were 1,193 Japanese subjects (775 men, 418 women; age: 20-84 years old, body mass index (BMI): 14.9-56.4 kg/m2) including subjects undergoing a health examination and obese subjects visiting an obesity clinic. Visceral fat area (VFA) and subcutaneous fat area (SFA) were determined by computed tomography (CT) at the umbilical level. Anthropometric parameters, including BMI, waist circumference (W), waist/hip circumference (W/H), ratio and waist circumference/body height (W/BH) ratio, were measured. Hyperglycemia, dyslipidemia, and hypertension were evaluated as obesity-related complications. The relationship between each parameter and the prevalence of the complications was investigated. The number of complications increased in accordance with BMI and the average value was greater than 1.0 at a BMI of 25. The best combination of the sensitivity and specificity for detecting subjects with multiple risk factors was a BMI of 25. BMI showed a close positive correlation with SFA (r=0.82), even for BMI ≥25 (r=0.77), but had a weaker correlation with VFA (r=0.54). The obese subjects with a BMI ≥25 had no correlation between BMI and VFA because of the wide individual variation of VFA. The number of disorders was greater than 1.0 at 100 cm2 of VFA and the best combination of the sensitivity and specificity for determining subjects with multiple risk factors was 100 cm2 of VFA. Between the simple anthropometric values and measurement of VFA, it was proven that W had the closest relationship with VFA in both men (r=0.68) and women (r=0.65). The regression line obtained from simple correlation analyses indicated that the W corresponding to 100 cm2 of VFA was 84.4 cm in men and 92.5 cm in women. These data suggest that obesity is adequately specified as a BMI ≥25 in Japan where the prevalence and degree of obesity remains mild. It is reasonable to establish the cut-off point of VFA at 100 cm2 as indicative of the risk of obesity-related disorders and a waist circumference of 85 cm in men and 90 cm in women approximates to this visceral fat mass.

Background:Whether the short-term effect of cardiac rehabilitation (CR) in elderly patients with heart failure (HF) is influenced by nutritional status is uncertain, so the present study investigated the effect of nutritional status on functional recovery after CR in elderly HF inpatients.Methods and Results:We enrolled 145 patients admitted for treatment of HF who were aged ≥65 years and had a low functional status defined as a Barthel index (BI) score ≤85 points at the commencement of CR. Nutritional status was assessed by the Mini Nutritional Assessment Short Form (MNA-SF) and total energy intake per day. The primary endpoint was functional status determined by the BI score at discharge. The median CR period was 20 days (interquartile range: 14–34 days), and 87 patients (60%) were functionally dependent (BI score ≤85) at discharge. Multivariate logistic regression analysis showed that MNA-SF score (odds ratio [OR]: 0.76, P=0.02) and total energy intake at the commencement of CR (OR: 0.91, P=0.02) were independent predictors of functional dependence after CR. MNA-SF score ≤7 and total energy intake ≤24.5 kcal/kg/day predicted functional dependence at discharge with moderate sensitivity and specificity.Conclusions:MNA-SF score and total energy intake at the commencement of CR are novel predictors of the extent of functional recovery of elderly HF inpatients after in-hospital CR.

Background: A corkscrew collateral appearance on angiography is one of the diagnostic criteria for Buerger's disease. The purpose of the present study was to classify the angiographic findings of corkscrew collaterals and to evaluate the relationship between corkscrew collateral type and the severity of Buerger's disease. Methods and Results: Corkscrew collaterals were assessed on digital subtraction angiography in lower extremities of 28 patients with Buerger's disease (55 limbs). The corkscrew sign was classified into 4 types by size and pattern as follows: type I, artery diameter >2 mm, large helical sign; type II, diameter >1.5 mm and ≤2 mm, medium helical sign; type III, diameter ≥1 mm and ≤1.5 mm, small helical sign; and type IV, diameter <1 mm, tiny helical sign. The prevalence of ischemic ulcers was significantly higher in patients with types III and IV corkscrew collaterals than in patients with types I and II corkscrew collaterals either below or above the knee. Multiple regression analysis indicated that types III and IV below the knee are independent predictors of risk of ischemic ulcers. Conclusions: The prevalence of ischemic ulcers is significantly higher in patients who have small corkscrew patterns in distal segments of limb collaterals than in patients who have large corkscrew collaterals.  (Circ J 2010; 74: 1684 - 1688)

Background:In the EMPA-REG OUTCOME®trial, empagliflozin added to standard of care reduced the risk of 3-point major adverse cardiovascular (CV) events (3-point MACE: composite of CV death, non-fatal myocardial infarction, or non-fatal stroke) by 14%, CV death by 38%, hospitalization for heart failure by 35%, and all-cause mortality by 32% in patients with type 2 diabetes (T2DM) and established CV disease. We investigated the effects of empagliflozin in patients of Asian race.Methods and Results:Patients were randomized to receive empagliflozin 10 mg, empagliflozin 25 mg, or placebo. Of 7,020 patients treated, 1,517 (21.6%) were of Asian race. The reduction in 3-point MACE in Asian patients was consistent with the overall population: 3-point MACE occurred in 79/1,006 patients (7.9%) in the pooled empagliflozin group vs. 58/511 patients (11.4%) in the placebo group (hazard ratio: 0.68 [95% confidence interval: 0.48–0.95], P-value for treatment by race interaction (Asian, White, Black/African-American): 0.0872). The effects of empagliflozin on the components of MACE, all-cause mortality, and heart failure outcomes in Asian patients were consistent with the overall population (P-values for interaction by race >0.05). The adverse event profile of empagliflozin in Asian patients was similar to the overall trial population.Conclusions:Reductions in the risk of CV outcomes and mortality with empagliflozin in Asian patients with T2DM and established CV disease were consistent with the overall trial population.
