Background: Few studies have comprehensively evaluated the trends and factors associated with CR participation across major cardiovascular diseases in Japan.Methods and Results: This study performed a nationwide cross-sectional study using the National Database of Health Insurance Claims and Specific Health Checkups of Japan and the Japanese Registry of All Cardiac and Vascular Diseases and the Diagnosis Procedure Combination database. This study described the nationwide trends and evaluated patient- and hospital-level associated factors of CR participation for patients with acute heart failure (AHF), acute coronary syndrome (ACS), acute aortic dissection (AAD), peripheral artery disease (PAD), and after cardiovascular surgery using mixed-effect logistic regression analysis. Although the annual number of patients who underwent CR has increased during the study period, the total number of patients participating in outpatient CR was lower than that of inpatient CR. The outpatient CR participation rate was lower for patients with AHF (3.5%), AAD (3.2%), and PAD (1.7%), compared with ACS (7.9%) and after surgery (9.4%). Age, sex, body mass index, Barthel index, Charlson comorbidity index, and institutional capacity were identified as significant associated factors of CR participation in inpatient and outpatient settings.Conclusions: Participation in outpatient CR was still low, and higher age, multi-comorbidity, and low institutional capacity contributed to the lower outpatient CR participation rate. Identification of the associated factors may help cardiologists to increase CR participation.

Background:The cost-effectiveness of percutaneous coronary intervention (PCI) for ischemic heart disease is undetermined in Japan. The aim of this study was to analyze the cost-effectiveness of PCI compared with medical therapy for ST-elevation myocardial infarction (STEMI) and angina pectoris (AP) in Japan.Methods and Results:We used Markov models for STEMI and AP to assess the costs and benefits associated with PCI or medical therapy from a health system perspective. We estimated the incremental cost-effectiveness ratio (ICER), expressed as quality-adjusted life-years (QALY), and ICER <¥5 m per QALY gained was judged to be cost-effective. The impact of PCI on cardiovascular events was based on previous publications. In STEMI patients, the ICER of PCI over medical treatment was ¥0.97 m per QALY gained. The cost-effectiveness probability of PCI was 99.9%. In AP patients, the ICER of fractional flow reserve (FFR)-guided PCI over medical treatment was ¥4.63 m per QALY gained. The cost-effectiveness probability of PCI was 50.4%. The ICER of FFR-guided PCI for asymptomatic patients was ¥23 m per QALY gained.Conclusions:In STEMI patients, PCI was cost-effective compared with medical therapy. In AP patients, FFR-guided PCI for symptomatic patients could be cost-effective compared with medical therapy. FFR-guided PCI for asymptomatic patients with myocardial ischemia was not cost-effective.

Background:Because the early diagnosis of subclinical cardiac sarcoidosis (CS) remains difficult, we developed a deep learning algorithm to distinguish CS patients from healthy subjects using echocardiographic movies.Methods and Results:Among the patients who underwent echocardiography from January 2015 to December 2019, we chose 151 echocardiographic movies from 50 CS patients and 151 from 149 healthy subjects. We trained two 3D convolutional neural networks (3D-CNN) to identify CS patients using a dataset of 212 echocardiographic movies with and without a transfer learning method (Pretrained algorithm and Non-pretrained algorithm). On an independent set of 41 echocardiographic movies, the area under the receiver-operating characteristic curve (AUC) of the Pretrained algorithm was greater than that of Non-pretrained algorithm (0.842, 95% confidence interval (CI): 0.722–0.962 vs. 0.724, 95% CI: 0.566–0.882, P=0.253). The AUC from the interpretation of the same set of 41 echocardiographic movies by 5 cardiologists was not significantly different from that of the Pretrained algorithm (0.855, 95% CI: 0.735–0.975 vs. 0.842, 95% CI: 0.722–0.962, P=0.885). A sensitivity map demonstrated that the Pretrained algorithm focused on the area of the mitral valve.Conclusions:A 3D-CNN with a transfer learning method may be a promising tool for detecting CS using an echocardiographic movie.

Background:Transcatheter aortic valve replacement (TAVR) has been performed more and more frequently in elderly patients with aortic stenosis. We investigated the association of in-hospital availability of TAVR on outcomes of surgical aortic valve replacement (SAVR) in the era of TAVR.Methods and Results:We utilized data from the Japan Adult Cardiovascular Surgery Database. Between October 2013 and December 2016, 9,330 patients aged ≥80 years underwent isolated SAVR or SAVR with coronary artery bypass grafting in 557 centers in Japan. We assessed the associations of in-hospital TAVR availability with operative mortality and composite complications adjusting for each patient’s characteristics, JapanSCORE predicted the risk scores, and hospital volumes of SAVR using generalized estimation equation methods. Observed operative mortality rates were 3.4% in all centers, 2.0% in TAVR centers and 4.0% in non-TAVR centers. The multivariable analyses showed that TAVR centers had statistically significantly lower operative mortality compared with non-TAVR centers among all patients (odds ratio 0.60, 95% confidence interval 0.41–0.89, P=0.01) and among intermediate/high-risk patients (odds ratio 0.52, 95% confidence interval 0.32–0.85, P<0.01) but not among low-risk patients (odds ratio 0.82, 95% confidence interval 0.44–1.51, P=0.52).Conclusions:In-hospital TAVR availability was associated with better outcomes of SAVR among elderly patients. This association was statistically significant among intermediate/high-risk patients but not significant among low-risk patients.

Background:Hydrogen gas inhalation (HI) ameliorates cerebral and cardiac dysfunction in animal models of post-cardiac arrest syndrome (PCAS). HI for human patients with PCAS has never been studied.Methods and Results:Between January 2014 and January 2015, 21 of 107 patients with out-of-hospital cardiac arrest achieved spontaneous return of circulation. After excluding 16 patients with specific criteria, 5 patients underwent HI together with target temperature management (TTM). No undesirable effects attributable to HI were observed and 4 patients survived 90 days with a favorable neurological outcome.Conclusions:HI in combination with TTM is a feasible therapy for patients with PCAS.

Background Coronary calcification has been correlated with the presence and extent of coronary artery disease (CAD), so in the present study the associations between coronary artery calcification score (CACS) and endothelial dysfunction, as well as the important inflammatory markers C-reactive protein (CRP), interleukin (IL)-6, and oxidized low-density lipoprotein (OxLDL), were studied in asymptomatic individuals at intermediate risk for CAD. Methods and Results The study group comprised 177 subjects (103 males) aged 50.6±5.9 years. CACS was measured by multidetector computed tomography using the Agatston method. Endothelium-dependent flow-mediated dilatation (FMD) and endothelium-independent nitroglycerin-mediated dilatation (NMD) were measured by high-resolution external brachial ultrasound. Coronary artery calcification (CAC) was detected in 82 subjects (52 males), and the median CACS was 143 [31-311.25] units. After adjusting for gender and body mass index, log (CACS +1) correlated positively with age (r=0.401, p<0.001) and IL-6 levels (r=0.442, p<0.001), and negatively with FMD (r=-0.511, p<0.001). The correlations of log (CACS +1) with CRP and OxLDL levels, and with NMD, were non-significant. In a multivariate-adjusted logistic regression model, age (odds ratio (OR) =1.083 [1.014-1.156]), serum IL-6 level (OR=3.837 [2.166-6.798]) and FMD (OR=0.851 [0.793-0.913]) were significantly and independently associated with CAC. Conclusions Peripheral endothelial function inversely correlated with CACS, whereas IL-6 level was associated with CACS. Testing for endothelial function and IL-6 level may improve cardiovascular risk assessment and help target the therapeutic strategies in asymptomatic patients at intermediate CAD risk.

The devastating Great East Japan Earthquake, which was 9.0 on the Richter scale, occurred on March 11, 2011. Japan experienced the Great Hanshin-Awaji Earthquake 16 years ago, and I was working at the epicenter, and reported the characteristics of the earthquake-associated cardiovascular risk and high blood pressure (BP) found during the continuous practice and clinical studies of Tsuna Medical Association before and after the quake. A major disaster increases thrombophilic tendency and BP, both of which trigger disaster-induced cardiovascular events such as stroke, cardiac events, etc. The high salt intake and the increased salt sensitivity caused by disrupted circadian rhythms are the 2 major leading causes of disaster hypertension (HT) through neurohumoral activation under stressful conditions. To better assess and reduce the risks for disaster-associated cardiovascular events, we introduced the web-based Disaster Cardiovascular Prevention (DCAP) network (which consists of DCAP risk and prevention score assessment, and self-measured BP monitoring at both the shelter and the home) to the survivors of the 2011 disaster, and frequently found newly developed HT. Here I review the recent evidence, possible mechanism and the management of "disaster HT" for effective prevention of disaster-induced cardiovascular events. (Circ J 2012; 76: 553-562)

Until the 2017 ACC/AHA Hypertension Guidelines were released, the target blood pressure (BP) for adults with hypertension (HTN) was 140/90 mmHg in most of the guidelines. The new 2018 ESC/ESH, Canadian, Korean, Japan, and Latin American hypertension guidelines have maintained the <140/90 mmHg for the primary target in the general population and encourage reduction to <130/80 if higher risk. This is more in keeping with the 2018 American Diabetes Association guidelines. However, the 2017 ACC/AHA guidelines classify HTN as BP ≥130/80 mmHg and generally recommend target BP levels below 130/80 mmHg for hypertensive patients independently of comorbid disease or age. Although the new guidelines mean that more people (nearly 50% of adults) will be diagnosed with HTN, the cornerstone of therapy is still lifestyle management unless BP cannot be lowered to this level; thus, more people will require BP-lowering medications. To date, there have been many controversies about the definition of HTN and the target BP. Targeting an intensive systolic BP goal can increase the adverse effects of multiple medications and the cardiovascular disease risk by excessively lowering diastolic BP, especially in patients with high risk, including those with diabetes, chronic kidney disease, heart failure, and coronary artery disease, and the elderly. In this review, we discuss these issues, particularly regarding the optimal target BP.

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.

Background: The end-of-life (EOL) status, including age at death and treatment details, of patients with adult congenital heart disease (ACHD) remains unclear. This study investigated the EOL status of patients with ACHD using a nationwide Japanese database.Methods and Results: Data on the last hospitalization of 26,438 patients with ACHD aged ≥15 years, admitted between 2013 and 2017, were included. Disease complexity (simple, moderate, or great) was classified using International Classification of Diseases, 10th Revision codes. Of the 853 deaths, 831 patients with classifiable disease complexity were evaluated for EOL status. The median age at death of patients in the simple, moderate, and great disease complexity groups was 77.0, 66.5, and 39.0 years , respectively. The treatments administered before death to patients in the simple, moderate, and great complexity groups included cardiopulmonary resuscitation (30.1%, 35.7%, and 41.9%, respectively), percutaneous cardiopulmonary support (7.2%, 16.5%, and 16.3%, respectively), and mechanical ventilation (58.7%, 72.2%, and 75.6%, respectively). Overall, 70% of patients died outside of specialized facilities, with >25% dying after ≥31 days of hospitalization.Conclusions: Nationwide data showed that patients with ACHD with greater disease complexity died at a younger age and underwent more invasive treatments before death, with many dying after ≥1 month of hospitalization. Discussing EOL options with patients at the appropriate time is important, particularly for patients with greater disease complexity.

Background: Pulsed field ablation (PFA) is a non-thermal energy source with promising safety and efficacy advantages. We aimed to develop a convenient, safe, effective and fast method of pulmonary vein isolation (PVI) utilizing a penta-spline PFA catheter via a single femoral vein and a venous closure system.Methods and Results: Consecutive patients (n=50; mean age: 63.6±10.7 years, 38% female) presenting with AF (paroxysmal AF: 56%) underwent first-time PVI via PFA. A single ultrasound-guided femoral vein puncture and a single transseptal puncture were used. After PVI using the penta-spline PFA catheter, extra pulse trains were added to the posterior wall for wide antral circumferential ablation. A venous closure system was used and a Donati suture was performed. The pressure bandage was removed after 1 h. A total of 196 PVs were identified and isolated with PFA only. The mean procedural time was 27.4±6.6 min, and the mean dwelling time was 14.4±5.5 min. Time to ambulation was 3.3±3.1 h. No severe complications occurred. During a mean follow-up of 6.5±2.1 months, 41/50 patients (82%) remained in sinus rhythm.Conclusions: The combination of a single venous puncture, single transseptal puncture approach using PFA and vascular closure device resulted in a 100% rate of acute PVI and an extraordinarily fast procedure and time to ambulation. The rate of periprocedural complications was low.

Background: The HELT-E2S2score, which assigns 1 point to Hypertension, Elderly aged 75–84 years, Low body mass index <18.5 kg/m2, and Type of atrial fibrillation (AF: persistent/permanent), and 2 points to Extreme Elderly aged ≥85 years and previous Stroke, has been proposed as a new risk stratification for strokes in Japanese AF patients, but has not yet undergone external validation.Methods and Results: We evaluated the prognostic performance of the HELT-E2S2score for stroke risk stratification using 2 large-scale registries in Japanese AF patients (n=7,020). During 23,241 person-years of follow-up (mean follow-up 1,208±450 days), 287 ischemic stroke events occurred. The C-statistic using the HELT-E2S2score was 0.661 (95% confidence interval [CI], 0.629–0.692), which was numerically higher than with the CHADS2score (0.644, 95% CI 0.613–0.675; P=0.15 vs. HELT-E2S2) or CHA2DS2-VASc score (0.650, 95% CI, 0.619–0.680; P=0.37 vs. HELT-E2S2). In the SAKURA AF Registry, the C-statistic of the HELT-E2S2score was consistently higher than the CHADS2and CHA2DS2-VASc scores across all 3 types of facilities comprising university hospitals, general hospitals, and clinics. However, in the RAFFINE Study, its superiority was only observed in general hospitals.Conclusions: The HELT-E2S2score demonstrated potential value for risk stratification, particularly in a super-aged society such as Japan. However, its superiority over the CHADS2or CHA2DS2-VASc scores may vary across different hospital settings.
