Background:Many studies show that dietary factors such as vegetables, fruit, and salt are associated with cardiovascular disease (CVD) risk. However, a risk assessment chart for CVD mortality according to combinations of dietary factors has not been established.Methods and Results:Participants were 9,115 men and women aged 30–79 years enrolled in the National Nutritional Survey of Japan in 1980 with a 29-year follow-up. Dietary intake was assessed using a 3-day weighed dietary record at baseline. Cox regression models were used to estimate the hazard ratio (HR) of CVD mortality stratified by vegetables, fruit, fish, and salt consumption. HRs of CVD mortality according to combinations of dietary factors were color coded on an assessment chart. Higher intakes of vegetables, fruit, and fish, and lower salt intake were associated with lower CVD mortality risk. HRs calculated from combinations of dietary factors were displayed using 5 colors corresponding to the magnitude of the HR. People with the lowest intake of vegetables, fruit, and fish, and higher salt intake had a HR of 2.87 compared with those with the highest intake of vegetables, fruit, and fish, and lower salt intake.Conclusions:Vegetables, fruit, fish, and salt intake were independently associated with CVD mortality risk. The assessment chart generated could be used in Japan as an educational tool for CVD prevention.

Background: The prognostic implications and surgical benefit of isolated significant tricuspid regurgitation (TR) and prognostic factors in patients with TR were investigated. Methods and Results: In 870 consecutive patients with significant isolated TR, all-cause mortality was analyzed over 4.9±2.9 years. It was found that the survival rate tended to be higher in the 57 patients who underwent tricuspid valve (TV) surgery than the 813 patients who did not by using propensity-score matching (P=0.068), although it was not significant. Of the 813 patients that did not undergo TV surgery, the 5-year survival rate was 74%. According to the Cox proportional hazards model, the initial TR jet area (hazard ratio [HR], 1.044; 95% confidence interval [CI], 1.016-1.073), pulmonary artery systolic pressure (HR, 1.024; 95%CI, 1.017-1.032) and presence of right ventricular (RV) dysfunction (HR, 2.256; 95% CI, 1.329-3.828) were predictors of mortality independent of patient age and presence of diabetes mellitus and renal failure in medically managed patients. Conclusions: In patients with isolated significant TR, there was a tendency, although not significant, towards a higher survival rate after TV surgery. The severity of TR and pulmonary hypertension, and the presence of RV dysfunction are independent prognostic factors in medically managed patients. Further prospective randomized studies are necessary to demonstrate the benefit of TV surgery in these poor prognostic populations. (Circ J 2010; 74: 375-380)

Background:Nutritional status has been reported to be a predictor of the outcomes of critical limb ischemia. However, there have been no reports of the association between nutritional status and the prognosis of patients with intermittent claudication (IC). The aim of this study was to examine whether or not the geriatric nutritional risk index (GNRI) is independently associated with the long-term outcomes of elderly patients following open bypass for IC.Methods and Results:The preoperative nutritional status of patients aged ≥65 years undergoing infrainguinal bypass for IC between 1991 and 2017 was retrospectively evaluated using the GNRI. Patients were divided into 3 groups based on the GNRI: Group I (normal nutritional risk), GNRI >98; Group II (low nutritional risk), GNRI 92 to ≤98; Group III (moderate to high nutritional risk), GNRI <92. The amputation-free survival (AFS), overall survival, and freedom from cardiovascular death up to 5 years were calculated by Kaplan-Meier method and a multivariate analysis was performed to detect independent predictors of each outcome. Group I showed superior outcomes to Group III for each of the 3 outcomes and the multivariate analysis showed that GNRI was an independent predictor of AFS.Conclusions:The GNRI was independently associated with the AFS of elderly patients who underwent open bypass for IC.

Background:A therapeutic strategy in patients with atrial septal defect (ASD) and significant pulmonary arterial hypertension (PAH) remains controversial. This study aimed to assess the effect of PAH-specific medications and subsequent transcatheter shunt closure (ie, a treat and repair strategy) in these patients.Methods and Results:Among 646 patients with ASD, 22 patients (mean age of 56±20 years) who had PAH [mean pulmonary artery pressure ≥25 mmHg and pulmonary vascular resistance (PVR) ≥3 Wood units] underwent successful transcatheter ASD closure. Prior to the procedure, 8 patients received PAH-specific medications (PHM group) and 14 patients did not (non-PHM group). Initially, the PHM group had higher PVR compared with non-PHM group (9.6±3.8 vs. 4.2±1.0 Wood units, P<0.01). After treatment with PAH-specific medications, PVR in this group decreased to 4.0±0.8 Wood units (P<0.01). No adverse events were observed in either the PHM or non-PHM group during or after the transcatheter procedure. In the PHM group, during a treatment period of 52±48 months, the World Health Organization Functional Classification significantly improved (3.0±0.5 to 2.0±0.0, P<0.01), as well as in the non-PHM group (2.1±0.6 to 1.5±0.5, P<0.01).Conclusions:Treat and repair strategy provided substantial improvement and no worsening of the WHO-FC, even in patients with ASD and significant PAH. Long-term hemodynamic follow-up is mandatory to evaluate the ultimate efficacy and safety of this new strategy. (Circ J 2016; 80: 227–234)

Background:Hemocompatibility-related adverse events (HRAEs) are substantial issues in patients with left ventricular assist devices (LVADs). Atrial fibrillation (AF) is associated with worse prognosis in patients with heart failure (HF), but its effect on HRAEs following LVAD implantation remain uncertain.Methods and Results:Data from the Japanese Mechanically Assisted Circulatory Support registry of consecutive patients who received HeartMate II LVADs and were followed for 1 year were retrospectively reviewed. Among 190 patients, 23 had AF and 167 had sinus rhythm. The AF group had comparable baseline characteristics with the non-AF group except for their higher age (53 vs. 42 years, P<0.001). Following LVAD implantation, most cases of AF (73%) persisted. Antiplatelet therapy, anticoagulation therapy, and LVAD speed following LVAD implantation were comparable between groups (P>0.05 for all). The 1-year survival free from HRAEs was comparable between groups (83% vs. 76%, P=0.52). Event rates of the breakdown of HRAEs were comparable between groups except for a relatively higher rate of surgically managed pump thrombosis in the AF group (0.16 vs. 0.04, incidence rate ratio 3.75, 95% confidence interval 0.87–16.1, P=0.075). These trends still remained with propensity score-matched comparison.Conclusions:Existence of AF had no effect on the development of HRAEs following LVAD implantation. The need to aggressively treat AF before or after LVAD implantation needs further investigation.

Background:Primary percutaneous coronary intervention (pPCI) is strongly recommended by guidelines for patients presenting with acute myocardial infarction (AMI), but its applications in elderly patients are less clear.Methods and Results:The JROAD-DPC is a Japanese nationwide registry for patients with cardiovascular diseases combined with an administrative claim-based database. Among 2,369,165 records from 2012 to 2015, data for 115,407 AMI patients were extracted for this study. Elderly patients (≥75 years) comprised 45,645 subjects (39.6%), and received pPCI less frequently (62.2%) than younger patients (79.2%, P<0.001). Clinical variables such as higher age, female sex, higher Killip class, and renal dysfunction, but not functional status on admission, were predictors of non-application of pPCI. Endpoint 30-day mortality increased with aging, and was significantly higher in elderly patients (10.7%) than in younger patients (3.8%, P<0.001). Indeed, pPCI was independently associated with lower 30-day mortality only in subgroups of patients aged ≥60 years. Propensity score-matching analysis confirmed a similar reduction in endpoint 30-day mortality with pPCI in elderly patients. Duration of hospitalization was significantly shorter and functional ability on discharge was significantly better in elderly patients who underwent pPCI.Conclusions:Elderly patients with AMI underwent pPCI less frequently, but it was consistently associated with better clinical outcome in these patients. Our findings support the proactive application of pPCI for elderly AMI patients when they are eligible for an invasive strategy.

Background: Weather conditions affect the occurrence of cardiovascular disease. The aim of this study was to investigate the associations between atmospheric conditions including temperature, pressure, and humidity, and the occurrence of out-of-hospital cardiac arrests (OHCAs) with cardiac etiology. Methods and Results: This study was a cross-sectional analysis of a prospective cohort that included all persons aged ≥18 years with OHCA in Osaka, from 1998 through 2007. The association between the number of daily OHCA events with various atmospheric conditions was analyzed using Poisson regression. A total of 28,806 adult OHCAs were presumed to be of cardiac etiology. The number of OHCAs in 1 day was inversely correlated with the day’s mean atmospheric temperature. The regression coefficient was greater on the days under 18°C (r=–0.317, P<0.001) than on days over 18°C (r=–0.088, P<0.001). A positive linear relation was found between the number of OHCAs in 1 day and the day’s mean atmospheric pressure (r=0.321, P<0.001). Under 18°C, every 5°C decrease in the daily mean temperature was associated with an 11% (95% confidence interval [CI]: 8–13%) increase in OHCA occurrence in the non-elderly group, and a 16% increase in the elderly group (95% CI: 14–19%). Conclusions: The occurrence of adult OHCA with cardiac etiology increases with decreasing temperature of the day. Elderly people are more susceptible to severe weather conditions.  (Circ J 2013; 77: 2073–2078)

Background:Little information is available in Asia about the real-world practice of dual antiplatelet therapy (DAPT) duration for acute coronary syndrome (ACS) and its influence on clinical outcomes.Methods and Results:The Taiwan ACS STENT Registry was a prospective, multicenter study to observe ACS patients using clopidogrel-based DAPT after percutaneous coronary intervention (PCI). The primary outcome was a composite of cardiovascular death, myocardial infarction, and stroke. Overall, 2,221 ACS patients (62 years, 83% men) were included. DAPT duration was ≤9 months in 935 (42.1%). The incidence of primary outcome was higher in patients receiving DAPT ≤9 months compared with those receiving DAPT >9 months at 1 year (3.5% vs. 1.6%, P=0.0026). The incidence of stent thrombosis (overall 0.5%) was similar between groups. Multivariable analysis showed that DAPT >9 months was associated with a significantly lower risk of primary outcome (odds ratio 0.725, 95% confidence interval 0.545–0.965).Conclusions:Our data showed that short duration of DAPT (≤9 months) was common (42.1%) in Taiwan for ACS patients undergoing PCI. DAPT ≤9 months increased the risk of the primary outcome.

Background: A disease management program can reduce mortality and rehospitalization of patients with heart failure (HF), but little is known about whether it can improve psychological status. The purpose of this study was to determine the effects of home-based disease management on the psychological status of patients with HF. Methods and Results: We randomly assigned patients hospitalized for HF to undergo either home-based disease management (n=79) or usual care (n=82). The mean age of the study patients was 76 years, 30% were female, and 93% were in NYHA class I or II. Home-based disease management was delivered by nurses via home visit and telephone follow-up to monitor symptoms and body weight and to educate patients. The primary endpoint was psychological status, including depression and anxiety assessed by the Hospital Anxiety and Depression Scale during follow-up of 1 year. Secondary endpoints included quality of life, all-cause death and hospitalization for HF. The intervention group had significantly lower depression (P=0.043) and anxiety (P=0.029) scores than the usual-care group. There were no significant differences in all-cause death [hazard ratio (HR) 1.02, 95% confidence interval (CI) 0.37–2.61, P=0.967]. However, hospitalization for HF was significantly lower in the intervention group than in the usual-care group (HR 0.52, 95% CI 0.27–0.96, P=0.037). Conclusions: Home-based disease management improved psychological status and also reduced rehospitalization for HF in patients with HF.  (Circ J 2013; 77: 926–933)

<b><i>Background:</i></b> Left ventricular (LV) mechanical dyssynchrony can lead to impairment of LV function and is associated with adverse clinical outcomes in coronary artery disease (CAD) patients. The impact of LV dyssynchrony on exercise capacity (EC) in patients with CAD was investigated. <b><i>Methods and Results:</i></b> An echocardiographic examination with tissue Doppler imaging and exercise treadmill testing in 151 CAD patients with normal LV ejection fraction was performed. LV intra- and inter-ventricular dyssynchrony were defined by the standard deviation of time interval between LV 6 basal segments (Ts-SD), and the time interval from the right ventricular (RV) free wall to LV lateral wall (Ts-RV) respectively, and EC was measured as metabolic equivalents (METs) on the treadmill. Patients with impaired EC (defined by a METs &le;8, which is the mean MET of the study population) were older (71&plusmn;7 vs. 62&plusmn;2 years, P<0.01), however, there were no differences in gender and clinical status such as prevalence of prior myocardial infarction (MI), regional wall motion abnormality (RWMA), and coronary revascularization between patients with (n=90) or without (n=61) impaired EC. Univariate analysis showed that age, body mass index, LV systolic and diastolic volume, mitral inflow A velocity, and Ts-SD were all significantly associated with METs (all P<0.05). However, multivariate regression analysis revealed that old age (odd ratio [OR]: 1.136, 95% confidence interval [CI]: 1.080-1.196, P<0.001), and Ts-SD (OR: 1.026, 95%CI: 1.003-1.049, P=0.027) only were independent predictors for impaired EC. <b><i>Conclusions:</i></b> In patients with CAD, LV systolic dyssynchrony predicts impaired EC independently of history of previous MI or RWMA.

Background:We investigated the risk of cardiovascular disease (CVD) with duration of metabolic syndrome (MetS) for the past 4 years before the CVD event.Methods and Results:We performed a nested case-control study within the Japan Epidemiology Collaboration on Occupational Health Study. A total of 139 registered cases of CVD and 561 self-reported cases of CVD were identified and matched individually on age, sex, and worksite with 695 and 2,803 controls, respectively. MetS was defined by the Joint Interim Statement definition. The odds ratio (95% confidence interval) for registered CVD was 4.7 (2.9, 7.5) for people with persistent MetS (positive for MetS for ≥3 assessments) and 1.9 (1.1, 3.3) for those with intermittent MetS (positive for MetS for 1–2 assessments), compared with people without MetS during the past 4 years before the event/index date (P for trend <0.001). The corresponding odds ratio for self-reported CVD was 2.7 (2.2, 3.5) and 1.8 (1.4, 2.3) (P for trend <0.001). The association with MetS duration was stronger for myocardial infarction than for other CVD subtypes. Similar results were obtained when using the Japanese MetS criteria.Conclusions:The risk of CVD increases with increasing MetS duration. These findings contribute to risk stratification and encourage lifestyle modification for people with MetS to minimize their health risk.

Background: Global Anticoagulant Registry in the FIELD-Atrial Fibrillation (GARFIELD-AF) is an ongoing prospective non-interventional study of stroke prevention in patients with newly diagnosed non-valvular AF (NAVF) that is being conducted in 35 countries. Methods and Results: A total of 52,081 patients with a new diagnosis of NVAF were enrolled prospectively in GARFIELD-AF. Of these, 4859 (9.3%) were recruited in Japan (2010–2016). In cohort 1 (2010–2011), few patients were on non-vitamin K antagonist oral anticoagulants (NOAC) globally. From cohort 2 onwards (2011–2016), however, there was a rapid increase in NOAC use around the globe, especially in Japan. By the last year of enrolment (2015–2016), 67.9% of patients in Japan and 43.1% of patients globally were on NOAC±antiplatelet therapy (AP). In Japan and globally, 17.0% and 12.2% of patients, respectively, did not receive stroke prevention treatment. Few patients in Japan (5.7%) received AP only. Compared with the other countries, the unadjusted rates of all-cause mortality and major bleeding were low, while rates of stroke/systemic embolism were similar after 1 year of follow-up. Conclusions: GARFIELD-AF continues to provide important information on the homogeneity and heterogeneity of baseline characteristics and treatment patterns in patients with newly diagnosed NVAF. This diversity reflects the differences in outcomes in Japan compared with the rest of the world.

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.

The identification of corticotropin-releasing hormone (CRH) has led to the discovery of a growing family of ligands and receptors. CRH receptor 1 (CRHR1) and CRHR2 are mammalian G-protein coupled receptors (GPCRs) with high affinity for CRH and the CRH family of peptides. CRHR1 is predominantly expressed in the brain and plays a vital role in the hypothalamic-pituitary-adrenal (HPA) axis stress responses by secreting adrenal corticotropic hormone (ACTH). CRHR2 is predominantly expressed in the heart, and a CRHR2-specific ligand, urocortin 2 (UCN2), shows positive cardiac chronotropic and inotropic effects through 3´,5´-cyclic adenosine monophosphate (cAMP) signaling in response to CRHR2-mediated Gαs activation in mice and humans. Central administration of the CRH family of peptides increases mean arterial pressure through CRHR1 activation, whereas peripheral administration of the peptides decreases mean arterial pressure through CRHR2 activation. These observations have led to further investigations of CRHR2 as an important and unique GPCR in the physiological and pathological functioning of the cardiovascular (CV) system. Moreover, recent clinical trials demonstrate CRHR2 as a potentially therapeutic target in the treatment of heart failure. We present recent reviews of the role of CRHRs in basic CV physiology and in the pathophysiology of CV diseases.

Background:Prasugrel has been shown to provide more potency and less variability than clopidogrel, but its potential temporal variability has not been described.Methods and Results:We conducted a prospective open-label study, evaluating platelet reactivity overtime in acute coronary syndrome (ACS) patients on aspirin and clopidogrel (n=60) or prasugrel (n=61), after a percutaneous coronary intervention (PCI). Blood samples were taken at discharge and at 3 and 6 months. Platelet function tests included VerifyNow (VN-P2Y12), and Multiplate Aggregometry (MEA). By means of VN-P2Y12, prasugrel patients displayed significantly (P<0.001) higher platelet inhibition than clopidogrel patients over time, although there were not significant differences using MEA. Prasugrel patients showed higher platelet inhibition at baseline than at 3 months (59.3±8.1 vs. 105.0±49.2; P<0.001), without significant change at 6 months (107.9±72.0; P=0.919 vs. 3 months). Clopidogrel patients showed a similar trend (160.1±65.1, 184.8±62.7 and 185.0±53.3; baseline vs. 3 months P=0.060; 3 months vs. 6 months P=0.974). High platelet reactivity (HPR) was shown in 16.3% prasugrel patients, with no patient consistently remaining in HPR over time. HPR was detected in 36.6% of the clopidogrel patients, being consistently observed in 15.0% of them. Low platelet reactivity (LPR) was detected in 60.5% prasugrel and 9.8% clopidogrel patients.Conclusions:Prasugrel patients showed less temporal variation than patients on clopidogrel in terms of HPR. In contrast, higher variability in LPR was detected in prasugrel patients for up to 6 months’ follow-up.
