Abstract
Phospholipids are major components of biological membranes and play structural and regulatory roles in various biological processes. To determine the biological significance of phospholipids, the use of chemical inhibitors of phospholipid metabolism offers an effective approach; however, the availability of such compounds is limited. In this study, we performed a chemical-genetic screening using yeast and identified small molecules capable of inhibiting phosphatidylcholine (PC) biogenesis, which we designated PC inhibitors 1, 2, 3, and 4 (PCiB-1, 2, 3, and 4). Biochemical analyses indicated that PCiB-2, 3, and 4 inhibited the phosphatidylethanolamine (PE) methyltransferase activity of Cho2, whereas PCiB-1 may inhibit PE transport from mitochondria to the endoplasmic reticulum (ER). Interestingly, we found that PCiB treatment resulted in mitochondrial fragmentation, which was suppressed by expression of a dominant-negative mutant of the mitochondrial division factor Dnm1. These results provide evidence that normal PC biogenesis is important for the regulation of mitochondrial division.

Abstract
Palladium-catalyzed ipso-borylation of aryl halides, well-known as Miyaura borylation, is one of the reliable synthetic methods for organoborons. This reaction involves base-mediated nucleophilic activation of diboron that enables transmetalation of an aryl(halo)palladium(II) intermediate with a diboron. As an alternative, herein, we have established Lewis acid-mediated conditions for borylating (pseudo)haloarenes that require no external base. The electrophilic activation of the aryl(halo)palladium(II) intermediate via dehalogenation with Lewis acidic zinc complexes promotes the borylation.

Abstract
Interactions between plants and herbivores are central in most ecosystems, but their strength is highly variable. The amount of variability within a system is thought to influence most aspects of plant-herbivore biology, from ecological stability to plant defense evolution. Our understanding of what influences variability, however, is limited by sparse data. We collected standardized surveys of herbivory for 503 plant species at 790 sites across 116° of latitude. With these data, we show that within-population variability in herbivory increases with latitude, decreases with plant size, and is phylogenetically structured. Differences in the magnitude of variability are thus central to how plant-herbivore biology varies across macroscale gradients. We argue that increased focus on interaction variability will advance understanding of patterns of life on Earth.

Abstract
A concise route for dibenzoazacyclooctynes (DIBACs) synthesis was developed based on Pictet-Spengler reaction and a novel cobalt decomplexation method established for dibenzo-fused cyclooctyne-cobalt complexes. The method allowed for the facile preparation of functionalized DIBACs, including bisDIBAC, which served as an efficient bisreactive linker for protein modification via the double-click reaction.

Abstract
Research on the automated control of robots for wiping curved surfaces includes studies on cleaning contaminated areas and controlling the end-effector posture to apply a constant force along curved surfaces. However, such robots should also clean difficult-to-find contaminants such as dust and dirt. One of previous studies has considered motion generation as a generalized traveling salesman problem. In particular, a point cloud is acquired from an RGBD camera, and a large graph is created to represent the surface based on the point cloud. The system then finds an appropriate end-effector posture for each node and sets up multiple coordinate systems. Consequently, an efficient cleaning motion can be generated; however, path generation using the previous study is a highly time-consuming process. Therefore, in this study, a 3D model is used to generate cleaning actions more efficiently. A point cloud is then generated from the mesh data of the 3D model, based on which the surface is represented as a simple graph that can be solved as a traveling salesman problem, thereby reducing the computational time. The optimal end-effector posture is determined based on the shape of the surface and is set as the coordinate system for each node. Finally, experiments are conducted to compare the cleaning results with the previous study results, thereby verifying that results can be obtained in less than one-tenth the computational time required for the previous study results.

Abstract
Abstract
Background
Systemic inflammation resulting from comorbidities is postulated to play a central role in the pathophysiology of heart failure (HF) with preserved ejection fraction (HFpEF). Lymphopenia is a common manifestation of systemic inflammation and a prognostic factor in patients with HF. However, the association of lymphopenia with the comorbidity burden is unknown, and its prognostic value in patients with HFpEF admitted due to acute decompensated heart failure (ADHF) also remains elusive.
Purpose
We sought to clarify the relation of lymphopenia with the comorbidity burden, as well as its prognostic value and complementarity with the Get with the Guidelines-Heart Failure (GWTG-HF) risk score in ADHF patients with HFpEF.
Methods
Patients' data were extracted from the Prospective mUlticenteR obServational stUdy of patIenTs with Heart Failure with Preserved Ejection Fraction (PURSUIT-HFpEF), which is a prospective multicentre registry for patients with ADHF with a LVEF ≥50%. We analysed data of patients admitted between June 2016 and December 2020 who survived to discharge. The total lymphocyte count (per μL) and GWTG-HF risk score were obtained on admission, as previously reported. Comorbidity burden was defined as the number of comorbidities from the following: atrial fibrillation, hypertension, diabetes mellitus, coronary artery disease, chronic kidney disease, chronic obstructive pulmonary disease, anaemia, and obesity. The study endpoint was all-cause death.
Results
Over a median follow-up of 417 days, 181 of the 1013 included patients died. The proportion of patients with a total lymphocyte count in the lowest tertile was increasing with the increase in comorbidity burden (Figure 1). In the multivariate Cox analysis, a total lymphocyte count in the intermediate (hazard ratio [HR] 1.55, 95% confidence interval [CI] 1.00–2.41, p=0.0486) and lowest tertile (HR 2.23, 95% CI 1.47–3.38, p=0.0002) was independently associated with all-cause death. There was a significant difference in the all-cause death rate among the groups stratified by total lymphocyte count tertile (Figure 2). The total lymphocyte count had a higher C-statistic value (0.627) for the prediction of all-cause death than the GWTG-HF risk score, and the C-statistic value of the GWTG-HF risk score was improved when the total lymphocyte count was added (0.613 to 0.636, p=0.0260).
Conclusions
Lymphopenia was significantly associated with comorbidity burden. Furthermore, it was a useful marker of poor prognosis in hospitalised patients with acute HFpEF and was shown to be complementary to the contemporary HF prognostic score.

Abstract
Abstract
Background
Heart failure (HF) with preserved ejection fraction (HFpEF) is a chronic and progressive disease, but limited therapeutic strategies are currently available. Although left ventricular diastolic dysfunction (DD) is a prominent mechanism of HFpEF, a certain number of patients with HFpEF have a normal diastolic function (ND) or indeterminate diastolic function (ID). With the progressive nature of HFpEF, diastolic function may change over time. However, the change of diastolic function, its predictor and prognosis in patients with clinically established HFpEF remains unknown.
Purpose
To investigate the clinical trajectory and outcomes of patients with HFpEF with ND or ID and to identify factors associated with progression from ND or ID at discharge to DD at 1-year follow-up.
Methods
Using data from a prospective multicenter observational study of patients with HFpEF, we extracted 289 patients with HFpEF with ND or ID at discharge who had echocardiographic data at 1-year follow-up for the re-evaluation of diastolic function. Diastolic function was assessed according to the 2016 American Society of Echocardiography recommendations. Patients were classified according to the absence or presence of progression from ND or ID to DD at 1 year. The primary endpoint was a composite of all-cause death and HF rehospitalization.
Results
Median age was 81 years, and 138 (47.8%) patients were female. At 1 year, 107 (37%) patients progressed to DD. During a median follow-up of 709 days, the composite endpoint occurred in 90 (31.1%) patients. Compared to patients without progression to DD, those with progression to DD had a significantly higher cumulative incidence rate of the composite endpoint (incidence rate: 11.7/100 person-year versus 23.3/100 person-year, P<0.001). Progression to DD (adjusted HR: 2.014, 95% CI: 1.239–3.273, P=0.005) was independently associated with the composite endpoint. Age (adjusted OR: 1.046, 95% CI: 1.008–1.087, P=0.018), body mass index (BMI) (adjusted OR: 1.107, 95% CI: 1.029–1.192, P=0.006), and serum albumin (adjusted OR: 0.459, 95% CI: 0.216–0.974, P=0.042) were independently associated with progression from ND or ID to DD at 1 year.
Conclusion
More than one-third of patients with HFpEF with ND or ID progressed to DD at 1 year and had poor clinical outcomes. Age, BMI, and serum albumin were independently associated with this progression.

Extensive ablation strategy for persistent atrial fibrillation impairs left atrial function but reduces recurrence rate. Eur Heart J 2022.

Abstract
Abstract
Background
In catheter ablation for persistent atrial fibrillation (AF), extensive ablation strategy, such as linear ablation and/or complex fractionated atrial electrogram (CFAE) ablation in addition to pulmonary vein isolation (PVI-plus), might impair left atrial function more severely than PVI-alone strategy.
Purpose
The aim of this study is to investigate the impact of extensive ablation strategy on LA function and assess the relationship between post-ablation LA function and recurrence.
Methods
This study is a post-hoc subanalysis of the EARNEST-PVI randomized controlled trial, which investigated the efficacy of the PVI-alone strategy in comparison with PVI-plus strategy for persistent AF. From the 497 participants of EARNEST-PVI trial, we enrolled 191 patients with full datasets of pre- and post-ablation cardiac computed tomography (CT) at our Hospital. Patients were divided into PVI-alone and PVI-plus groups. Within one month before and 3 months after ablation, LA volume index (LAVI) and LA emptying fraction (LAEF) were calculated by using the Comprehensive Cardiac Analysis software on the Extended Brilliance Workspace. We assessed i) post-ablation LA function, ii) AF/atrial tachycardia (AT) -free rate after single and final session, and iii) relationship between post-ablation LAEF and ablation success in each group.
Results
The indices of baseline LA remodeling were not different between PVI-alone (N=96) and PVI-plus groups (N=95) [LAVI: 71.4 (57.8, 82.0) vs. 68.7 (61.0, 78.1), P=0.92, LAEF: 13.7 (10.0, 17.4) vs. 13.0 (10.0, 16.9), PVI-alone vs. PVI-plus, P=0.78]. In overall patients, post-ablation LAEF did not differ among them [34.4 (26.1, 40.7) vs. 31.6 (26.0, 37.4), P=0.13]. In the analysis of patients showing sinus rhythm during the CT study, LAEF was significantly higher in PVI-alone (N=87) than in PVI-plus group (N=93) [35.7 (29.0, 41.0) vs. 31.7 (26.1, 37.5), P=0.011] (Figure 1A). AF/AT-free survival rate during median follow-up of 44 months was not different after first session (63.5% vs. 68.4%, P=0.33), while PVI-plus had a tendency towards higher success rate after final session (72.9% vs. 84.2%, P=0.053) (Figure 2). In receiver operating characteristics analysis for recurrence after first session, post-ablation decreased LAEF had significantly related to recurrence after PVI-alone (AUC: 0.733, P<0.0001), but not after PVI-plus (AUC: 0.567, P=0.31) (Figure 1B, C).
Conclusion
Compared with PVI-alone strategy, PVI-plus strategy damaged LA function more severely, but tended to be related to higher success rate. Post-ablation LA function was related to recurrence in PVI-alone, but not in PVI-plus. Extensive ablation might have additional anti-arrhythmic effect regardless of iatrogenic myocardial damage. Myocardial injury by extensive ablation may less attribute to recurrence than intrinsic damage of LA.

Abstract
Abstract
Background/Introduction
New onset of atrial fibrillation (AF) is associated with adverse short- and long-term outcomes after acute myocardial infarction (AMI), and its prediction is relevant for the risk stratification in patients with AMI. Although several risk scores were developed for AF in the general population, there is no established risk score for AF occurrence after AMI.
Purpose
To develop a risk score to predict occurrence of AF early after AMI.
Methods
We enrolled consecutive 751 patients with AMI who admitted to our hospital between April 2006 and September 2012 for the present study. New occurrence of AF was defined as AF detected during hospital stay in a patient showing normal regular sinus rhythm at admission. Parameters relevant to the occurrence of AF was selected from the clinical characteristics, physical status and blood test data at admission, and peak CK/CK-MB, by stepwise logistic regression analysis. We constructed a risk score model to predict the new occurrence of AF, using selected parameters and their logistic regression coefficients. C-statistics was determined by constructing a receiver operating characteristic curve to evaluate the accuracy of the risk score for prediction of AF occurrence.
Results
We excluded 48 patients (6.4%) who had AF at admission, and 208 patients without sufficient data at admission, and thus, the study group consisted of 459 patients (age; 65±13 years, male gender; 79.6%). New AF occurrence was observed in 72 patients (14.5%). The following 7 parameters was selected as parameters related with AF (as p<0.1); Inferior/posterior AMI, use of β blockers, use of diuretics, single vessel disease, absence of reperfusion therapy, systolic blood pressure (sBP) at admission, and smoking. One point was given to sBP>128mmHg, 2 points to absence of reperfusion, and one point to other parameters. Sum of these points was calculated as the AF risk score (Table 1). AF occurred in 27.1% of patients with ≥5 points whereas it was observed 5.2% of those with <5 points. C-statistics of the risk score was 0.75 (95% CI 0.68–0.83).
Conclusion
We developed a novel risk score to estimate the risk of AF occurrence early after AMI, which can be a useful tool for the risk stratification after AMI.

Abstract
Abstract
Background
The effectiveness of angiotensin-converting enzyme inhibitors (ACE-I) and angiotensin II receptor blockers (ARB) has not been demonstrated in patients with heart failure with preserved ejection fraction (HFpEF). We recently reported significant interaction between the use of ACE-I and/or ARB (ACE-I/ARB) and frailty on prognosis in patients with HFpEF.
Purpose
In the present study, we examined the association between ACE-I/ARB and prognosis in patients with HFpEF stratified by the presence or absence of frailty.
Methods
We examined the association between the use of ACE-I/ARB and prognosis according to the presence (Clinical Frailty Scale (CFS) ≥5) or absence (CFS ≤4) of frailty in patients with HFpEF in a post-hoc analysis of registry data. Primary endpoint was the composite of all-cause mortality and heart failure admission. Secondary endpoints were all-cause mortality and heart failure admission.
Results
Of 1059 patients, median age was 83 years and 45% were male. Kaplan-Meier analysis showed that the risk of composite endpoint (log-rank P=0.001) and all-cause death (log-rank P=0.005) in patients with ACE-I/ARB was lower in those with CFS ≥5, but similar between patients with and without ACE-I/ARB in patients with CFS ≤4 (composite endpoint: log-rank P=0.830; all-cause death: log-rank P=0.192). In a multivariable Cox proportional hazards model, use of ACE-I/ARB was significantly associated with lower risk of the composite endpoint (hazard ratio = 0.52, 95% CI: 0.33–0.83, P=0.005) and heart failure admission (hazard ratio = 0.45, 95% CI: 0.25–0.83, P=0.010) in patients with CFS ≥5, but not in patients with CFS ≤4 (composite endpoint: hazard ratio = 1.41, 95% CI: 0.99–2.02, P=0.059; heart failure admission: hazard ratio = 1.43, 95% CI: 0.94–2.18, P=0.091). The association between ACE-I or ARB and prognosis did not significantly differ by CFS (CFS ≤4: log-rank P=0.562; CFS ≥5: log-rank P=0.100, for with ACE-I vs. ARB, respectively). Adjusted HRs for CFS 1–4 were higher than 1.0, but were less than 1.0 at CFS 5.
Conclusions
In patients with HFpEF, use of ACE-I/ARB was associated with better prognosis in patients with frailty as assessed with the CFS, but not in those without frailty.

Abstract
Abstract
Background
Improvement of quality of life (QOL) is one of the most important therapeutic goals for patients with heart failure with preserved ejection fraction (HFpEF). It is, therefore, clinically relevant to comprehensively identify aggravating factors among cardiac factors, non-cardiac comorbidities, and social factors. The aim of this study was to elucidate determinant factors of impaired QOL and clarify the association between QOL and prognosis in patients with HFpEF.
Methods and results
Patient data were extracted from The Prospective mUlticenteR obServational stUdy of patIenTs with Heart Failure with Preserved Ejection Fraction (PURSUIT HFpEF) study. EuroQol 5 dimensions 5-level (EQ-5D-5L) data were obtained at discharge to evaluate patients' health-related QOL. A total of 864 patients were enrolled in this study. Multivariable logistic regression analysis revealed that only non-cardiac factors such as age, female sex, frailty, malnutrition and inflammation were significantly associated with low EQ-5D-5L score, whereas cardiac factors showed no significant association after multivariable adjustment. A total of 206 patients died over a mean follow-up period of 2.0±1.2 years. Kaplan–Meier survival curve analysis demonstrated a significant increase in risk of mortality stratified by tertiles of EQ-5D-5L score (p<0.0001). Cox multivariable analysis revealed that patients with low EQ-5D-5L score had a significantly greater risk of mortality than those with high EQ-5D-5L score (adjusted hazard ratio: 2.20 (1.40–3.45), p=0.001).
Conclusion
Among patients with HFpEF, non-cardiac factors such as age, female sex, frailty, malnutrition and inflammation are significantly associated with impaired QOL. The QOL score itself also offers useful prognostic information in patients with HFpEF.

Abstract
Abstract
Background
There are several reports showing that elevated heart rate (HR) is associated with poor outcomes in patients in sinus rhythm (SR) with heart failure with preserved ejection fraction (HFpEF), although the association is weak or none in HFpEF patients with atrial fibrillation (Af). However, in previous studies, cardiac and non-cardiac factors which may be associated with elevated HR, have not been fully adjusted for.
Purpose
The purpose of this study is to explore covariates of elevated HR and to investigate the relationship between heart rate and mortality in HFpEF patients in SR.
Methods and results
Of the 1161 patients, who registered prospective multicenter, observational study of patients with HFpEF (PURSUIT-HFpEF), 726 patients in SR were examined. We performed laboratory testing and echocardiography in the compensated stage (in stable condition after treatment of acute decompensated HF). Geriatric nutritional risk index (GNRI) was calculated as nutrition index. Resting heart rate (HR) was analyzed as categorical (tertiles, T1–3). We followed the patients for median of 598 days (interquartile range 329–1028 days) to observe the outcome all-cause mortality.
The Kaplan analysis revealed that there was a significant difference between heart rate and mortality (log-rank, p=0.001). Characteristics were compared between patients in T1 (HR ≤63) and T3 (HR ≥75). There were no differences in cardiac factors between patients in T1 and T3. C-reactive protein (CRP) was significantly higher in patients in T3 than those in T1 (p=0.0004,). GNRI was significantly lower in patients in T3 than those in T1 (p=0.001). After adjustment for covariates including N-terminal pro-B type natriuretic peptide and estimated glomerular filtration rate, CRP and GNRI significantly correlated with HR (continuous variable) by multiple regression analysis (beta-coefficient = 1.52, p=0.003 and beta-coefficient = −0.14, p=0.04, respectively). Taking T1 as the reference, multivariable Cox regression analysis revealed that T3 was independently associated with mortality (hazard ratio: 2.10, 95% confidence interval: 1.33–3.32, p=0.001).
Conclusion
Although elevated HR was associated with enhanced inflammation and malnutrition, it itself was an independent predictor of death in HFpEF patients in SR.

Abstract
Abstract
Background
Malnutrition and inflammation are associated with poor outcomes with heart failure (HF). It has been reported that advanced lung cancer inflammation index (ALI), calculated by body mass index × serum albumin level / neutrophil to lymphocyte ratio (NLR) can be useful for the risk stratification and predicting the post-discharge prognosis of the patients with acute decompensated heart failure (ADHF). However, there is no information available on the prognostic value of the serial ALI change in ADHF patients with preserved ejection fraction (HFpEF).
Methods and results
Patients' data were extracted from The Prospective mUlticenteR obServational stUdy of patIenTs with Heart Failure with Preserved Ejection Fraction (PURSUIT HFpEF) study, which is a prospective multicenter observational registry for ADHF-HFpEF in Osaka. Laboratory data and body weight measurements were performed at the discharge and 1 year after the discharge. We analyzed 527 patients after exclusion of patients on dialysis, in-hospital death, missing follow-up data, or missing data to calculate ALI. The study patients were categorized by the serial change from baseline to 1 year after the discharge (ΔALI) as follows: low tertile: ΔALI <−6.99 (n=176), middle tertile: −6.99 ≤ ALI <8.44 (n=176), and high tertile: 8.44 ≤ ΔALI (n=175). The endpoints of the present study were all-cause death (ACD) and cardiovascular death (CVD). During a mean follow-up period of 1.5±1.0 years, 94 patients had ACD and 40 patients had CVD. The Kaplan-Meier analysis revealed that the patients with middle and low ΔALI at 1 year after heart failure hospitalization had a significantly greater risk of reaching the ACD and CVD than those with high ΔALI (ACD: 22% vs 22% vs 10%, p=0.0011, CVD: 10% vs 9% vs 3%, p=0.014). On multivariate Cox analysis, ΔALI was significantly associated with ACD independently of age, gender, serum NT-proBNP level, and baseline ALI after adjustment for NYHA functional class, serum creatinine level, serum hemoglobin level, serum CRP level, serum sodium level and LVEF.
Conclusion
This study showed that patients with the increased ALI after the discharge had improved outcome in comparison to those without the increased ALI. The serial change of ALI, a systemic inflammation-nutrition index, might be useful for stratifying ADHF patients with HFpEF at risk for the total mortality and cardiovascular mortality.

Abstract
Abstract
Introduction
It is important to detect the recurrence of atrial fibrillation (AF) after catheter ablation (CA) early, but the method of detection has not been established. The purpose of this study is to determine whether 24-h Holter electrocardiogram (ECG) can predict the recurrence of AF after CA.
Methods
We studied 336 patients of 497 patients enrolled in EARNEST-PVI trial to investigate whether the total number of premature atrial contraction (PAC) and the maximum number of PAC run by 24-h Holter ECG at 6 months after CA predicted AF recurrence after 6 months. We excluded 86 patients with recurrence by 6 months after CA and 75 patients without Holter ECG at 6 months after CA.
Results
Median age was 66 years, male were 77% and median follow-up period was 1138 days. Receiver operating characteristic curve analysis identified the total number of PAC ≥270 beats and the maximum number of PAC run ≥8 beats as the optimal cutoff for prediction of AF recurrence. Kaplan-Meier analysis showed patients with the total number of PAC ≥270 beats had more frequent AF recurrence than those without (Kaplan-Meier estimated 3-year AF recurrence rate 34% vs. 17%, Log-rank P=0.001) and patients with the maximum number of PAC run ≥8 beats had more frequent AF recurrence than those without (Kaplan-Meier estimated 3-year AF recurrence rate 33% vs. 20%, Log-rank P=0.006). Multivariate analysis revealed that the total number of PAC ≥270 beats and the maximum number of PAC run were significantly associated with AF recurrence (hazard ratio [95% confidence interval] 1.83 [1.16–2.91], P=0.01 and 1.01 [1.01–1.02], P=0.001, respectively)
Conclusion
The total number of PAC and the maximum number of PAC run on the Holter ECG may be useful in predicting AF recurrence after CA.

Abstract
AbstractA new method to synthesize multifunctionalized arenes from simple phenols through aryne intermediates is described. Multisubstituted aryne precursors were prepared from phenols by Ir-catalyzed C–H borylation, deborylthiolation, O-triflylation, S-oxidation, and further modification through ortho-deprotonation directed by the sulfoxide moiety. Various multisubstituted arenes were synthesized by transformations of highly functionalized aryne intermediates generated from the o-sulfinylaryl triflates.

Abstract
The iridium-catalyzed azide-thioalkyne cycloaddition was found to proceed much faster with benzyl azide than with phenyl azide. The high azido-type selectivity was also observed in other combinations of azides with different steric environments. This finding enabled the efficient assembly of three azidophilic molecules to triazido platforms by three sequential triazole-forming reactions.

Abstract
Background Blood volume (BV) is a critical factor for physical endurance in chronic stroke patients, while hypervolemia can worsen hypertension in these patients. This prospective study assessed whether rehabilitation combined with protein supplementation immediately after each exercise for 3 weeks would improve plasma volume (PV) and BV as well as physical endurance without worsening hypertension. Methods Ambulatory patients with chronic cerebrovascular disease who received a 3-week rehabilitation program with high protein jelly (intervention group [PG]; n = 8; 10-g protein) or protein-free jelly (control group [CG]; n = 8) consumed within 30 min after each exercise. PV and BV were assessed while measuring the 6-min walking distance (6MWD), peak oxygen consumption (VO2peak), strength of knee extension, and resting blood pressure before and after the intervention. Two-way ANOVA was used to determine whether there was an interaction of time × group. The difference between before and after intervention or between the groups by post-hoc test (Tukey’s test) at the level of P < 0.05. Results The 6MWD increased only in the PG (P = 0.001; an interaction of Group and Time, P = 0.037). PV and BV increased only in the PG (P < 0.05). VO2peak and strength of knee extension in the paralysed limb increased in both groups (P < 0.05). The resting blood pressure did not worsen after the intervention. Conclusions In chronic post-stroke patients, 3-week rehabilitation combined with protein intake immediately after exercise increased 6MWD simultaneously with increased PV and BV, but it did not increase resting blood pressure. The present regimen is acceptable and effective for ambulatory patients with chronic cerebrovascular disease.

Background
Predicting heart rate (HR) after restoration of sinus rhythm (SR) remains one of the challenges when performing catheter ablation (CA) of persistent atrial fibrillation (AF).
Purpose
To evaluate the association between pre-ablation HR during AF and post-ablation HR during SR, and whether the HR reduction is associated with AF recurrence.
Methods
The analysis was performed from the EARNEST-PVI trial, a randomized controlled trial designed to assess a CA strategy for persistent AF, which was conducted in the Osaka region of Japan. After excluding patients with beta-blocker prescription, a total of 216 patients (median age, 67 years; 20% female; 23% long-standing persistent AF) with AF rhythm at baseline and SR at discharge were enrolled in this study. Baseline HR during AF and post-ablation HR during SR was measured on admission and at discharge using the 12-lead electrocardiograms, respectively.
Results
There was a mild correlation between baseline HR (median 82 [interquartile range 72-95] bpm) and post-ablation HR (78 [48-117] bpm) (r = 0.27, p <0.001). Reduction in HR was positively associated with baseline HR (r = 0.79, p <0.001) and was negatively associated with post-ablation HR (r = - 0.37, p <0.001). During the follow-up of 1 year, 56 patients (25.9%) experienced AF recurrence. HR reduction had the higher diagnostic accuracy in predicting AF recurrence than HR at baseline and HR after CA (area under the curve, 0.625; 95% confidence interval, 0.557–0.690; p = 0.003). AF recurrence rate was significantly higher in 141 patients with smaller HR reduction (cut-off, <14bpm) than those with larger HR reduction (31.9% vs. 14.7%, p = 0.009). After adjustment of age, gender, long-standing persistent AF, and CA strategy, HR reduction of <14 bpm was a significant predictor of AF recurrence (hazard ratio, 2.32; 95% confidence interval, 1.20–4.51; p = 0.013).
Conclusions
There was a mild correlation between HR during AF and HR after restoration of SR in patients underwent CA of persistent AF. HR reduction after restoration of SR predicted AF recurrence.

Abstract
Background: Middle-aged and older individuals with spinal cord injury (SCI) often require long-term care even after receiving rehabilitation treatment, making it difficult for them to return home. We retrospectively investigated our active rehabilitation treatment for patients with SCI. Case: Included in this case series were ten patients with SCI who were admitted to our general hospital (located in the southern part of Wakayama Prefecture) and who underwent active rehabilitation treatment. The participants were investigated retrospectively by access to electronic medical records. The Barthel index scores for discharged patients were determined at an outpatient clinic, and the community phase of rehabilitation management was recorded. The average age of the 10 patients was 67.4 ± 13.4 years, and the average period from onset to transfer to our hospital was 102.6 ± 69.9 days. The Barthel index scores significantly improved from 39.0 ± 30.9 at admission to 65.0 ± 28.2 at discharge (P<0.05). Among the seven patients who were discharged to their homes, six had cervical SCI. Some patients with American Spinal Injury Association impairment scale grades A and B at admission could be discharged home, and their Barthel index scores were maintained after discharge. Discussion : Even in a remote rural hospital, the activities of daily living of patients with SCI improved, and seven of the ten patients were discharged home. The activities of daily living of the discharged patients were maintained. To achieve these results, active rehabilitation treatment conducted by rehabilitation specialists is important.

Abstract
We report a Buchwald-Hartwig amination compatible with azido functionality. Treatment of azidoaryl iodides and amines with fourth-generation Buchwald precatalyst coordinated by CPhos and sodium tert-butoxide in 1,4-dioxane at 50 °C afforded the corresponding azidoanilines while leaving the azido groups intact. The method showed a broad substrate scope and was applicable to the synthesis of diazido compounds as photoaffinity probe candidates of pharmaceutical amines and multiazido platform molecules.

Abstract
Abstract
Background
Clinical heterogeneity exists in heart failure with preserved ejection fraction (HFpEF). Left ventricular (LV) structure in HFPEF is characterized by normal LV cavity size and LV hypertrophy (LVH). However some of HFPEF patients do not have LV hypertrophy, and these patients may have distinct characteristics,
Purpose
The purpose of this study is to clarify the clinical characteristics and the prognosis for HFPEF patients without LVH.
Methods
We studied 1097 patients, who were hospitalized for acute decompensated heart failure with LVEF ≥50%, and enrolled in the PURSUIT-HFpEF registry. Laboratory testing and echocardiography were examined in the compensated stage (in stable condition after treatment of acute decompensated HF). We divided these patients into 2 groups based on LV mass index (LVMI) in the compensated stage according to the American Society of Echocardiography/European Association of Cardiovascular Imaging recommendations; patients with LVH (48%) and those without LVH (52%).
Results
Patients without LVH had significantly lower levels of C-reactive protein and N-terminal pro brain natriuretic peptide (NT-proBNP) and higher levels of estimated glomerular filtration rate in the compensated stage than those with it (p<0.05 for all). Cox hazard regression analysis showed that absence of LVH was favorably associated with the primary composite endpoint of all-cause death, HF rehospitalization, and cerebrovascular events (hazard ratio 0.776, 95% confidence interval 0.620-to 0.970, p<0.05).
On the other hand, the frequency of atrial fibrillation (Af) in the decompensated stage was higher in patients without LVH than those with it (52.1% vs 39.3%, p<0.001). Multivariate logistic analysis showed that absence of LVH was independently associated with presence of Af in the decompensated stage (odds ratio=1.520, 95% confidence interval 1.130 to 2.050, P<0.01)
Conclusions
HFPEF patients without LVH have less organ damage and favorable prognosis. Af may play a role in the decompensation of HF in HFPEF patients without LVH.

Abstract
Abstract
Background
Diagnosing heart failure with preserved ejection fraction (HFpEF) is still challenging, and the H2FPEF- and the HFA-PEFF score were proposed as simple and reliable diagnostic tools. We recently reported that the HFA-PEFF score was significantly associated with the composite endpoint of all-cause death and heart failure readmission in patients with acute decompensated HFpEF (Sotomi. Eur J Heart Fail, in press).
Purpose
To investigate the relation whether the HFA-PEFF or H2FPEF score can evaluate functional capacity in patients with HFpEF
Methods
We calculated H2FPEF score and the second step of HFA-PEFF score among the registered patients in the PURSUIT-HFpEF (Prospective, Multicenter, Observational Study of Patients with Heart Failure with Preserved Ejection Fraction) study, which is a multicenter registration of patients hospitalized for acute decompensated HFpEF. We performed 6 minute walk (6MW) test and measured NT-proBNP before discharge. We followed the study patients for median of 360 days (IQR 237–630 days) to observe the major adverse cardiovascular events (MACE; composite of death, heart failure hospitalization and stroke).
Results
We enrolled 757 patients (age 81±9 years, male gender 45%) hospitalized for acute decompensated HFpEF for the present study. The H2FPEF score was obtained in 588 (77.7%) patients and all patients had ≥2 points. The HFA-PEFF score was obtained in 615 (81.2%) patients, though global longitudinal strain was not available. We divided these patients into 3 groups based on the HFA-PEFF score (score 2 to 4, 5, and 6) or on the H2FPEF score (score 0 to 3, 4 to 5 and 6 to 8). There were a significant difference in NT-pro BNP between 3 groups based on HFA-PEFF score (p=0.01, Table 1), and patients with score 6 had significantly higher NT-proBNP than those with score 2 to 4 (p=0.02). A significant difference was observed in 6MW distance among these groups (p=0.04, Table), and those with score 6 had significantly shorter distance than those with score 2 to 4 (p=0.04). Cox proportional hazard model selected HFA-PEFF score as a significant predictor for MACE, and Kaplan-Meier survival analysis demonstrated that classification of HFA-PEFF score significantly stratified the patients' risk for MACE. On the other hand, there was no significant difference in 6MW distance among 3 groups based on H2FPEF score (p=0.53), and H2FPEF score was not an independent predictor for MCE by the Cox model analysis. Moreover, the lowest H2PEF score group had higher NT-proBNP than other 2 groups (p=0.02)
Conclusions
The HFA-PEFF score predicted functional capacity as well as prognosis in patients hospitalized for HFpEF, while the H2PEF score did not.

Abstract
Abstract
Background
Subclinical inflammation is an important pathogenesis of developing and sustaining atrial fibrillation (AF). Because AF itself contribute to the inflammatory response, the role of baseline subclinical inflammation on AF recurrence after catheter ablation (CA) remains controversial in patients with persistent AF.
Purpose
To evaluate whether baseline plasma C-reactive protein (CRP) levels, a sensitive marker of inflammation, are associated with AF recurrence following CA.
Methods
The analysis was performed from the EARNEST-PVI trial, a randomized controlled trial designed to assess a CA strategy for persistent AF, which was conducted in the Osaka region of Japan. A total of 441 patients (median age, 67 years; 26% female; 25% long-standing persistent AF) whose plasma CRP levels were measured at baseline were included in this study.
Results
At baseline, a median (interquartile range) of plasma CRP level was 0.10 [0.06–0.19] mg/dl. Plasma CRP levels significantly increased at discharge (0.83 [0.21–1.84] mg/dl, p<0.001) and decreased 1 year after CA (0.10 [0.05–0.20] mg/dl, p=0.040) compared to the baseline value. During the follow-up of 1 year, 115 patients (26%) experienced AF recurrence, and the incidence was significantly higher in 124 patients with low CRP levels at baseline (cut-off ≤0.06 mg/dl) than the other 317 patients (33.9% vs. 23.0%, p=0.017). After adjustment of age, gender, body mass index, long-standing persistent AF, CA strategy, and plasma brain natriuretic peptide levels, low plasma CRP levels was a significant predictor of AF recurrence (hazard ratio, 1.51; 95% confidence interval, 1.02–2.24; p=0.042).
Conclusions
Low plasma CRP levels at baseline predicted AF recurrence in the EARNEST-PVI trial. Reappraising the role of CRP on AF recurrence may be needed in patients with persistent AF.

Abstract
Abstract
Background
Atrial fibrillation (AF) reduces the renal function. Renal dysfunction and AF often coexist. Catheter ablation (CA) of persistent AF can maintain a sinus rhythm and may improve the renal function.
Purpose
We sought to elucidate whether the estimated glomerular filtration rate (eGFR) in patients with persistent AF was increased after CA, especially with the presence of an AF recurrence.
Methods
We enrolled 487 persistent AF patients whose eGFR data were available both before and 1-year after the CA out of 512 patients in the EARNEST-PVI trial.
Results
The mean age was 65±9 year and 113 patients (24.8%) had long-standing persistent AF. We compared the eGFR at baseline with that 1-year after the CA. AF recurrences were recognized in 118 patients (25.8%). The eGFR was similar between the group without recurrence and that with recurrence at baseline (without AF recurrence vs. with AF recurrence; 63.8±14.3 vs. 62.7±13.6 mL/min/1.73m2, p=0.46). In patients without AF recurrence, the G1, G2, G3a, G3b, G4, and G5 were 13 (3.8%), 198 (58.4%), 98 (28.9%), 26 (7.7%), 3 (0.9%), and 1 (0.3%), respectively at baseline. In the patients with AF recurrence, the G1, G2, G3a, G3b, G4, and G5 were 3 (2.5%), 68 (57.8%), 38 (32.2%), 6 (5.1%), 3 (2.5%), and 0 (0%), respectively at baseline. The ΔeGFR was significantly higher in the patients without AF recurrence than in those with AF recurrence (without AF recurrence vs. with AF recurrence; 5.1 [−0.3, 10.8] vs. 3.0 [−3.0, 7.6], p=0.0033). In the patients without AF recurrence, a better eGFR class at 1-year after the CA than in those before the CA was recognized in 75 patients (22.1%), while it was recognized in 19 patients (16.1%) with AF recurrences.
Conclusion
Successful catheter ablation in patients with persistent AF led to a better renal outcome.

Abstract
Abstract
Background
Functional mitral regurgitation (FMR) is not uncommon in atrial fibrillation (AF) patients. Left atrial (LA) substrate remodeling and corresponding mitral valve annulus dilation has been reported as the most possible cause of FMR. Percutaneous catheter ablation (CA) is an effective treatment for AF. Although significant FMR could be improved by sinus restoration, patients with mitral regurgitation were more likely to experience recurrent AF post ablation, especially those with significant mitral regurgitation. There is no information available on the efficacy of CA for persistent AF in patients with FMR.
Purpose
The purpose of this study is to investigate the predictors of FMR improvement by CA and to determine the efficacy of substrate and trigger CA for persistent AF in patients with FMR.
Methods
We prospectively studied 512 consecutive patients admitted for persistent AF ablation from the EARNEST-PVI (Prospective Multicenter Randomized Study of Effect of Extensive Ablation on Recurrence in Patients with Persistent Atrial Fibrillation Treated with Pulmonary Vein Isolation) trial.
On admission, enrolled patients were randomly assigned in a 1:1 ratio to pulmonary vein isolation (PVI) or PVI-plus additional ablation (linear ablation or/and CFAE ablation). Of the 512 patients, we studied 94 patients with preoperative echocardiography showing moderate or greater baseline FMR. FMR grades were classified into 5 grades (0/1/2/3/4). The FMR improvement group (FMRI(+)) was defined as a case in which the FMR was improved by two or more grades compared the preoperative echocardiography and the one year follow-up examination.
Results
Of the 94 patients, 42 were in the PVI group and 52 were in the PVI-plus additional ablation group. There were 30 cases in the FMRI(+) group and 64 cases in the FMRI(−) group. There were no significant baseline differences in age, sinus rhythm maintenance, plasma B-type natriuretic peptide (BNP) level, left ventricular diastolic dimension, or left atrium dimension between the FMRI(+) and FMRI(−) groups. AF duration was significantly shorter in the FMRI(+) group than FMRI(−) groups (5.8±9.4 months vs 12.4±15.4 months, p<0.0001). In addition, significantly more additional ablation cases were observed in the FMRI(+) group than in the FMRI(−) group (73.3% vs 46.8%, p=0.016). In multivariate analyses, only additional ablation was an independent predictor of FMRI (odds ratio 0.226 95% CI 0.081–0.626; p=0.004).
Conclusions
Catheter ablation is a valid option for the treatment of AF in patients with functional MR and additional substrate and trigger ablation were the only independent predictor of FMR improvement.

Abstract
Abstract
Background
Improving the quality of life (QoL) is one of the main purposes of catheter ablation (CA) of persistent atrial fibrillation (AF). QoL improvement in persistent AF patients has not been fully clarified. The EARNEST-PVI trial was a multi-center randomized trial comparing clinical outcomes of pulmonary vein isolation (PVI) alone and more intensive ablation in addition to PVI including complex fractionated atrial electrogram (CFAE) and linear ablation (PVI plus).
Purpose
To investigate the QoL change after persistent AF ablation and the differences between the PVI-alone strategy and the PVI plus strategy.
Methods
In the EARNEST-PVI trial, patients with persistent AF who underwent an initial catheter ablation (n=512) were randomly assigned in a 1:1 ratio to either PVI alone or PVI plus. Quality of life was assessed at baseline and at 12 months after ablation for AF using the 36-Item Short Form Health Survey. Scores were also converted to a physical health component summary (PCS), a mental health component summary (MCS) and a role/social component summary (RCS).
Results
In the EARNEST-PVI trial, the PVI alone strategy was associated with higher recurrence rate compared with the PVI plus additional ablation strategy. After excluding 68 patients for whom preoperative or postoperative QoL assessment was not available, 222 patients were evaluated respectively. Overall, significant improvements in PCS (46.2±11.4 to 48.7±11.4]), MCS (50.1±8.8 to 54.3±8.6) and RCS (44.6±13.3 to 48.6±11.3) occurred 12 months after ablation (P<0.001, respectively). Although significant QoL improvement occurred in both PVI alone and PLI plus strategies, the changes in PCS was greater in the PVI-plus than that in PVI-alone (3.5±10.3 vs 1.5±10.6, P=0.04).
Conclusions
Ablation for persistent atrial fibrillation improved both physical and mental quality of life. The PVI-plus strategy showed greater improvement in physical QoL.

Abstract
Abstract
Background
Diagnosing heart failure with preserved ejection fraction (HFpEF) still remains challenging, and simple and reliable diagnostic tools have been required. Recently, novel and evidence-based diagnostic algorithms for HFpEF were proposed, such as H2FPEF score (Circulation. 2018) and HFA-PEFF score (Eur Heart J 2019), and their accuracy was validated in the outside patient group. However, there are regional and ethnic variations in patient characteristics of HFpEF, particularly between Western and Asian countries, and it is not elucidated whether these diagnostic scores are useful in Asian population.
Purpose
To investigate the validity of the HFA-PEFF- and H2FPEF score in Japanese patients with HFpEF.
Methods
We calculated H2FPEF score and the second step of HFA-PEFF score among the registered patients in the PURSUIT-HFpEF (Prospective, Multicenter, Observational Study of Patients with Heart Failure with Preserved Ejection Fraction) study, which is a multicenter registration of patients hospitalized for HFpEF. The obtained scores were compared with the scores of the HFpEF cohort in the previous validation studies. We followed the study patients for median of 360 days (IQR 237–630 days) to observe the major adverse cardiovascular events (MACE; composite of death, heart failure hospitalization and stroke).
Results
We enrolled 757 patients hospitalized for HFpEF between June 2016 and August 2019 for the present study. H2FPEF score was obtained in 588 (77.7%) patients among them. Compared with the HFpEF cohorts in the previously reported sub-analysis of TOPCAT trial, the PURSUIT-HFpEF cohort had lower mean value of HFpEF score (4.0±1.8 points vs. 6.0±2.0 points in Americans or 5.3±1.9 points in Russians). It had significantly higher proportion (40.3%, p<0.001) of patients in the low likelihood of HFpEF category (0–3 points) than the TOPCAT cohorts (8.0% in Americans and 19.6% in Russians).
HFA-PEFF score was obtained in 615 (81.2%) patients, though global longitudinal strain was not available. The mean value of HFA-PEFF score was 5.0±0.8, and all patients had ≥2 points. The proportion of patients in the high likelihood of HFpEF category (5–6 points) was 88.3%, which was significantly higher (p<0.001) than those of the HFpEF cohort from Europe and USA in the previous validation study (Eur J Heart Fail 2019). There was no correlation between H2FPEF score and HFA-PEFF score (R=0.06, p=0.14). Cox proportional hazard model selected HFA-PEFF score as a significant predictor for MACE during follow-up period, whereas H2PEF score was not selected. Kaplan-Meier survival analysis demonstrated that patients with 6 points of HFA-PEFF score had higher incidence rate of MACE than those with ≤5 points (p=0.002).
Conclusion
The HFA-PEFF score could be more useful for the diagnosis and risk stratification for HFpEF than the H2PEF score in the Japanese cohort.

Abstract
An efficient preparation method of functionalized phosphines by copper-catalyzed azide-alkyne cycloaddition (CuAAC) through the transient protection of phosphine from the Staudinger reaction is disclosed. Diverse phosphines were prepared from phosphinyl alkynes and azides by the click reaction at the ethynyl group without damaging the phosphinyl group. Double- and triple-click assemblies of azides were accomplished by triazole formations and robust azaylide formation.

Abstract
Abstract
Background
The novel nutrition index; triglyceride (TG) × total cholesterol (TG) × body weight (BW) index (TCBI) has been reported to be an easy and useful predictor for patients with coronary artery disease. However, there is no information available on the prognostic value of TCBI in patients with heart failure with preserved LVEF (HFpEF) who admitted with acute decompensated heart failure (ADHF).
Methods and results
Data were extracted from The Prospective mUlticenteR obServational stUdy of patIenTs with Heart Failure with Preserved Ejection Fraction (PURSUIT HFpEF) study. PURSUIT-HFpEF study is a prospective multicenter observational study in which collaborating hospitals recorded clinical, echocardiographic, and outcome data of ADHF pts with HFpEF. We enrolled consecutive 757 HFpEF patients who admitted with ADHF from June 2016 to June 2019. TCBI was calculated by the formula; TG × TC × BW / 1000 at the discharge. After we excluded patients with in-hospital death or without sufficient data, we analyzed 419 patients. The primary endpoint was all-cause mortality. During a median follow up period of 1.1 (0.9–1.9) years, 59 patients died. ROC analysis revealed that TCBI at discharge was a fair discriminator for predicting all-cause mortality (AUC 0.676, sensitivity 53%, specificity 78%). Multivariate Cox proportional analysis showed that TCBI (p=0.002) was an independent predictor for all cause death after adjustment with major confounders such as age, gender, NT-proBNP, hemoglobin and serum creatinine level. We divided patients into 4 groups according to quartiles of TCBI. Kaplan-Meier analysis showed a significantly higher risk of all-cause death in relation to the decrease in TCBI.
Conclusion
TCBI, a simple and novel nutrition index, is a useful and strong long-term prognostic indicator in ADHF patients with HFpEF.

Abstract
Abstract
Background
Heart failure (HF) with preserved ejection fraction (HFpEF) can develop pulmonary hypertension (PH), which can result from pre-capillary PH as well as post-capillary PH. However, the prevalence and clinical significance of pre-capillary component of PH in HFpEF remain unknown.
Purpose
We aimed to investigate prevalence, clinical features, and prognostic impact of pre-capillary and/or post capillary PH associated with HFpEF.
Methods
From the PURSUIT-HFpEF (Prospective Multicenter Observational Study of Patients with Heart Failure with Preserved Ejection Fraction) registry, 204 patients (men: 46%, age: 79±9 years) who were hospitalized with HF and underwent right heart catheterization were divided into 4 groups according to the PH guidelines: non-PH, isolated post-capillary PH (Ipc-PH), pre-capillary PH, and combined pre- and post-capillary PH (Cpc-PH). Patients who had been diagnosed with idiopathic pulmonary arterial hypertension were excluded from the analysis.
Results
The prevalence of PH was 31% (Ipc-PH: 22%, pre-capillary PH: 3%, Cpc-PH: 6%). The prevalence of subcategories of PH was significantly different depending on mean right atrial pressure (RAP) (figure). Echocardiography at discharge showed no significant differences in RV diameter or TAPSE, but smaller LV diameter and higher E/e' in pre-capillary PH and Cpc-PH, which resulted in a higher operant diastolic elastance (Ed). Composite endpoint of all-cause mortality and HF hospitalization at 1 year occurred 13% in non-PH, 25% in Ipc-PH, 49% in pre-capillary PH, and 63% in Cpc-PH, respectively (p=0.001 by log-rank test).
Conclusions
Distinct prevalence of PH was observed in the groups with different RAP levels. Pre-capillary component of PH was associated with impaired LV diastolic function and worse outcomes in HFpEF.

Abstract
Abstract
Background
Diuretics has been reported to have a potential for an activation of the renin-angiotensin-aldosterone system and the sympathetic nervous system, leading to a possibility of poor clinical outcome in patients with cardiovascular disease. However, few data are available on clinical impact of diuretics on long-term outcome in patients with acute myocardial infarction (AMI) based on plasma volume status.
Methods
To address the issue, a total of 3,416 survived patients with AMI who were registered to a large database of the Osaka Acute Coronary Insufficiency Study (OACIS) were studied. Plasma volume status was assessed with the estimated plasma volume status (ePVS) that was calculated at discharge as follows: actual PV = (1 − hematocrit) × [a + (b × body weight)] (a=1530 in males and a=864 in females, b=41.0 in males and b=47.9 in females); ideal PV = c × body weight (c=39 in males and c=40 in females), and ePVS = [(actual PV − ideal PV)/ideal PV] × 100 (%). Multivariable Cox regression analysis and propensity score matching were performed to account for imbalances in covariates. The endpoint was all-cause of death (ACD) within 5 years.
Results
During a median follow-up period of 855±656 days, 193 patients had ACD. In whole population, there was no significant difference in long-term mortality risk between patients with and without diuretics in both multivariate cox regression model and propensity score matching population. When patients were divided into 2 groups according to ePVS with a median value of 4.2%, 46 and 147 patients had ACD in groups with low ePVS and high ePVS, respectively. Multivariate Cox analysis showed that use of diuretics was independently associated with an increased risk of ACD in low ePVS group, (HR: 2.63, 95% confidence interval [CI]: 1.22–5.63, p=0.01), but not in high ePVS group (HR: 0.70, 95% CI: 0.44–1.10, p=0.12). These observations were consistent in the propensity-score matched cohorts; the 5-year mortality rate was significantly higher in patients with diuretics than those without among low ePVS group (4.7% vs 1.7%, p=0.041), but not among high ePVS group (8.0% vs 10.3%, p=0.247).
Conclusion
Prescription of diuretics at discharge was associated with increased risk of 5-year mortality in patients with AMI without PV expansion, but not with PV expansion. The role of diuretics on long-term mortality may differ in plasma volume status. Therefore, prescription of diuretics after AMI may be considered based on plasma volume status.

Abstract
Abstract
Background
Malnutrition is one of the most important comorbidities among heart failure (HF) patients, and serum cholinesterase (CHE) has been reported to be a prognostic factor in HF patients. On the other hand, atrial fibrillation (AF) is frequently observed in patients with HF with preserved ejection fraction (HFpEF). However, there is little information available on the prognostic value of nutritional status in HFpEF patients, with and without AF. We sought to clarify the prognostic value of CHE in HFpEF with and without AF and compare it with that of other nutrition indices such as gastric nutritional risk index (GNRI), controlling nutritional status (CONUT), and the prognostic nutritional index (PNI).
Methods and results
Patients data were extracted from The Prospective mUlticenteR obServational stUdy of patIenTs with Heart Failure with Preserved Ejection Fraction (PURSUIT HFpEF) study, which is a prospective multicenter observational registry for acute decompensated heart failure patients with left ventricular ejection fraction ≥50% in Osaka. We analyzed 380 patients (median age: 80 [75–87] years, male: 46%) after exclusion of patients with in-hospital death, missing follow-up data, or missing data to calculate nutritional indices. On admission, 155 patients had AF. Laboratory data were obtained at discharge. During a mean follow up period of 1.1±0.6 years, 131 patients had a composite endpoint (CE) of all-cause death and hospitalization for worsening heart failure or cerebrovascular disorder. In multivariate Cox analysis, in patients with AF, CHE was significantly associated with CE independently of age, gender and body mass index after the adjustment with serum albumin, total cholesterol levels and total lymphocyte count, while it was not significantly associated with CE in patients without AF. C-index of CHE (0.708) was higher than that of GNRI (0.555, p=0.0028), CONUT (0.651, p=0.208) and PNI (0.635, p=0.208) in AF patients, while there were no significant differences in those nutritional indices in patients without AF. Kaplan-Meier curve analysis revealed that AF patients with lower CHE (<208 U/L = median value) had higher risk of CE than those with higher CHE (44% vs 18%, adjusted HR 3.26 95% CI [1.66–6.67], p=0.0005), while there was no significant difference in the occurrence rate of CE between patients with and without higher CHE in non-AF group (42% vs 31%, adjusted HR 1.28 95% CI [0.78–2.13], p=0.33).
Conclusions
Prognostic value of CHE would be stronger than other nutritional indices in HFpEF patients with AF, while it would be weak in HFpEF patients without AF.

Abstract
Abstract
Introduction
Frailty and aging are two common conditions both associated with increased vulnerability to stressful events with high risk of adverse outcomes.
Purpose
To evaluate the association between frailty and aging and their impacts on clinical outcome in patients with heart failure with preserved ejection fraction (HFpEF).
Methods
Analysis was performed from a prospective multicenter observational registry for HFpEF (PURSUIT-HFpEF Registry) conducted in the Osaka region of Japan. A total of 757 patients hospitalized for acute heart failure (diagnosed by using Framingham criteria) met the inclusion criteria: a left ventricular ejection fraction ≥50% and brain natriuretic peptide ≥100pg/ml. We included 483 patients (age, 80±9 years; men, 45%; atrial fibrillation, 35%) whose follow-up data after survival discharge were available. Patients' frailty and aging were evaluated using the clinical frailty scale (CFS) and age quartiles (Q1: <76 years (n=122), Q2: 76–82 years (n=111), Q3: 82–87 years (n=127), Q4: >87 years (n=123)), respectively. The primary clinical endpoint was defined as the composite of death, re-hospitalization for heart failure, and cerebrovascular accident.
Results
The median (interquartile range) CFS rating was 3 (2–5), and there was a little correlation between CFS rating and age (r2=0.16, p<0.001). The prevalence of frailty, defined as a CFS rating >4 (n=132), was positively correlated with age quartiles (Q1: 9.0%, Q2: 21.4%, Q3: 29.9%, Q4: 48.0%, p<0.001). During the median follow-up period 396 days (interquartile range, 344–698) after discharge, the clinical endpoint was observed in 172 patients. The incidence was higher in patients with frailty than those without it (49.6% vs. 30.4%, log-rank p<0.001). It was also correlated with age quartiles (Q1: 23.0%, Q2: 34.2%, Q3: 36.2%, Q4: 48.8%, log-rank p=0.001). Multivariate Cox regression analysis revealed that frailty (hazard ratio, 1.52; 95% confidence interval, 1.09–2.10; p=0.013) and age (hazard ratio per quartile increase, 1.24; 95% confidence interval, 1.07–1.43; p=0.004) were both associated with the clinical endpoint. Subgroup analysis in 352 patients without frailty also revealed the significant impact of age on the endpoint (1.26; 1.06–1.51; p=0.008). However, in 131 patients with frailty, there was no significant impact of age on the endpoint (1.16; 0.90–1.51; p=0.25).
Conclusions
Frailty was common and was associated with aging in HFpEF patients. Although they were both associated with unfavorable events, aging was no longer a significant predictor of adverse outcomes under the frailty conditions.

Abstract
Abstract
Introduction
Structural remodeling is an important aspect of pathophysiology of heart failure (HF). The compensatory mechanism against diastolic dysfunction would be more obvious on the left atrium rather than left ventricle in HF with preserved ejection fraction (HFpEF).
Purpose
To investigate the impact of left atrial (LA) and left ventricular (LV) remodeling on clinical outcomes in HFpEF patients.
Methods
Analysis was performed from a prospective multicenter observational registry for HFpEF (PURSUIT-HFpEF Registry) conducted in the Osaka region of Japan. A total of 757 patients hospitalized for acute HF (diagnosed by using Framingham criteria) met the inclusion criteria: a LV ejection fraction ≥50% and brain natriuretic peptide ≥100pg/ml. We included 381 patients (age, 82±9 years; men, 45%; atrial fibrillation (AF), 34%) whose follow-up data after survival discharge were available and whose LA volume index (LAVI) and left ventricular end-diastolic volume index (LVEDVI) at discharge were measured by the biplane Simpson's method using echocardiography. The primary endpoint was defined as the composite of death, re-hospitalization for HF, and cerebrovascular accident.
Results
The LAVI and LVEDVI at discharge was 54±25 ml/m2 and 55±21 ml/m2, respectively (r2=0.014, p=0.021). When patients were classified into the LAVI tertiles groups (T1: <40ml/m2 (n=124), T2: 41–59ml/m2 (n=127), T3: >60ml/m2 (n=130)), there was a positive correlation between the prevalence of diastolic dysfunction and the LAVI tertiles (T1, 21.0%; T2, 48.8%; T3, 51.5%; p<0.001). On the other hand, significant association was not observed between the prevalence of diastolic dysfunction and the LVEDVI tertile groups (p=0.42). During the median follow-up period of 396 days (IQR, 345–698), the composite endpoint was observed in 131 patients and there was a positive correlation between the endpoint and the LAVI tertiles (T1, 24.2%; T2, 38.6%; T3, 40.3%; p=0.011). On the other hand, no correlation was found between the endpoint and the LVEDVI tertiles (p=0.13). After adjustment for age, gender, and presence of diastolic dysfunction, Cox regression analysis revealed that not LVEDVI but LAVI at discharge was a significant predictor of the composite endpoint in the entire cohort (hazard ratio per 10 ml/m2 increase; 1.09; 95% confidence interval, 1.02–1.16; p=0.009) and in the sinus rhythm subgroup (1.10; 1.01–1.20; p=0.034). However, not LAVI but LVEDVI was a significant predictor for the adverse outcomes in the AF subgroup (1.23; 1.04–1.46; p=0.016).
Conclusions
Increased LAVI at discharge, which was associated with diastolic dysfunction, related to unfavorable prognosis in patients with HFpEF. However, LAVI was no more a predictor for the adverse outcomes but LVEDVI was in the AF subgroup. The clinical significance of atrial and ventricular remodeling may differ between sinus rhythm and AF rhythm in HFpEF population.

Abstract
Abstract
Background
Shortening of onset to admission time (OAT) and door-to-balloon time (DBT) is associated with lower adverse cardiac event after primary percutaneous coronary intervention (PCI) in patients with acute myocardial infarction (AMI). Bleeding event also results in poor outcome in patients with AMI after primary PCI. Little is known about sex differences in DBT and ischemic, bleeding events after AMI.
Purpose
This study aimed to assess the sex differences of OAT, DTB and adverse cardiac event, incident of bleeding event after primary PCI in patients with AMI.
Methods
The Japan AMI Registry (JAMIR) is a multicenter, nationwide, prospective registry enrolling patients with AMI from 50 institutes between December 2015 and May 2017. Primary endpoints of this study were ischemic event (composite of cardiovascular death, myocardial infarction and ischemic stroke) and bleeding event (BARC type 3 or 5,).Median follow-up period was 12 months.
Results
A total of 3,411 patients were enrolled at first. Among them, 329 patients without treated with PCI and 199 patients missing OAT time were excluded from this study. A total 2883 patients of men (n=2240, 77.7%) and women (n=643, 22.3%) were enrolled. OAT and DBT of women were significantly longer than that of men (OAT: 130min, interquartile range 62–300 min vs. 155 min, interquartile range 69–350 min, p=0.040, DBT: 67 min, interquartile range 50–95 min vs. 75 min, interquartile range 53–120 min, p<0.001). There was no significant difference in ischemic events between men and women (7.1% vs. 7.5%, log-rank p=0.741, Figure 1). Multivariate Cox regression analysis showed female sex was significantly associated with lower ischemic event (hazard ratio 0.57; 95% confidence interval 0.38–0.85; p=0.007). Bleeding event of women was significantly higher than that of men (BARC type 3 or 5: 3.8% vs. 7.8%, p<0.001, Figure 2).
Conclusion
The real-world database of the JAMIR showed that the female sex was significant factor for the delay in primary percutaneous coronary intervention and high incident of bleeding, however, ischemic event was lower than that of male sex. Sex difference appears to be associated with ischemic and bleeding event after acute myocardial infarction.
