Abstract
Okinawa prefecture is a popular tourist destination due to its beaches and reefs. The reefs host a large variety of animals, including a number of venomous species. Because of the popularity of the reefs and marine activities, people are frequently in close contact with dangerous venomous species and, thus, are exposed to potential envenomation. Commonly encountered venomous animals throughout Okinawa include the invertebrate cone snail, sea urchin, crown-of-thorns starfish, blue-ringed octopus, box jellyfish, and fire coral. The vertebrates include the stonefish, lionfish, sea snake, and moray eel. Treatment for marine envenomation can involve first aid, hot water immersion, antivenom, supportive care, regional anesthesia, and pharmaceutical administration. Information on venomous animals, their toxins, and treatment should be well understood by prehospital care providers and physicians practicing in the prefecture.

Abstract
INTRODUCTION This study described, in routine clinical practice in Japan, the patient characteristics, treatment patterns, and outcomes of female patients with HR + /HER2- metastatic breast cancer (MBC) who started abemaciclib treatment. METHODS Clinical charts were reviewed for patients starting abemaciclib in 12/2018-08/2021 with a minimum of 3 months follow-up data post-abemaciclib initiation regardless of abemaciclib discontinuation. Patient characteristics, treatment patterns, and tumor response were descriptively summarized. Kaplan-Meier curves estimated progression-free survival (PFS). RESULTS 200 patients from 14 institutions were included. At abemaciclib initiation, median age was 59 years, and the Eastern Cooperative Oncology Group performance status score was 0/1/2 for 102/68/5 patients (58.3/38.9/2.9%), respectively. Most had an abemaciclib starting dose of 150 mg (92.5%). The percentage of patients receiving abemaciclib as 1st, 2nd, or 3rd line treatment was 31.5%, 25.8%, and 25.2%, respectively. The most frequent endocrine therapy drugs used with abemaciclib were fulvestrant (59%) and aromatase inhibitors (40%). Evaluation of tumor response was available for 171 patients, 30.4% of whom had complete/partial response. Median PFS was 13.0 months (95% CI 10.1-15.8 months). CONCLUSIONS In a routine clinical practice setting in Japan, patients with HR + , HER2- MBC appear to benefit from abemaciclib treatment in terms of treatment response and median PFS, with the results broadly reflecting the evidence demonstrated in clinical trials.

Abstract
Abstract
Background
Intracoronary optical coherence tomography (OCT) is a valuable tool for vulnerable plaque assessment and morphology-guided risk stratification. However the groundbreaking impact of OCT in clinical practice may be offset by its inherent limitation, the subjectivity in plaque interpretation. Recent studies reported a semi-automated method to assess fibrous cap thickness but data regarding an automated assessment of lipid component at OCT, such a lipid core burden index (LCBI), are lacking.
Purpose
The aim of this study was to assess the morphological characteristics and prognostic implications of an OCT-derived LCBI (OCT-LCBI).
Methods
In order to assess OCT-LCBI in 1003 patients with 1-year follow-up from the CLIMA multicenter registry (clinicaltrial.gov identifier NCT02883088) we used a novel previously validated software able to automate obtain a maximum OCT-LCBI in 4 mm (maxOCT-LCBI4mm). A maxOCT-LCBI4mm cut-off of 400 was used, based on previous literature on this topic. Primary composite clinical endpoint included cardiac death, myocardial infarction and target vessel revascularization. A secondary analysis using clinical outcomes of CLIMA study was performed.
Results
Patients with a maxOCT-LCBI4mm ≥400 showed higher prevalence of fibrous cap thickness <75μm (FCT, odds ratio [OR] 1.43, 95% confidence interval [CI] 1.03–1.99; p=0.034), lipid pool arc >180°(OR 3.93, 95% CI 2.97–5.21; p<0.001), minimum lumen area <3.5 mm2 (OR 1.5, 1.16–1.94; p=0.002), macrophage infiltration (OR 2.38, 95% CI 1.81–3.13; p<0.001) and intra-plaque intimal vasculature (OR 1.34, 95% CI 1.05–1.72, p=0.021). A maxOCT-LCBI4mm ≥400 predicted the primary endpoint (adjusted hazard ratio [HR] 1.86, 95% CI 1.1–3.2; p=0.019) as well as the CLIMA endpoint (HR 2.56, 95% CI 1.24–5.29; p=0.011). Patients with high lipid content and thin FCT <75 μm were at higher risk for adverse events (HR 4.88, 95% CI 2.44–9.72; p<0.001) (Figure 1).
Conclusions
We applied for the first time in a large population with clinical follow-up a software able to automatically obtain a maxOCT-LCBI4mm. A high maxOCT-LCBI4mm was related to vulnerable plaque features and further clinical events. This study represents a step further towards a comprehensive automated assessment of the coronary plaque risk profile.

Abstract
Abstract
Background
Near infrared spectroscopy – intravascular ultrasound (NIRS-IVUS) imaging can provide a fully automated estimation of lipid burden, providing a two-dimensional spread-out plot, the Lipid Core Burden Index (LCBI), which has been associated with higher incidence of cardiac events. Optical coherence tomography (OCT) can identify lipid component with high accuracy and it is therefore potentially capable of measuring its longitudinal extension in a dedicated two-dimensional LCBI spread-out plot.
Purpose
The present study has been designed to validate a novel automated approach to assess OCT images, able of providing a dedicated LCBI spread-out plot plus other features of plaque vulnerability.
Methods
We compared the results obtained with a novel automated OCT alghorithm, developed utilising a convolutional neural network, with those obtained with conventional (manual) OCT and with NIRS-IVUS in a consecutive series of 40 patients with coronary artery disease. We tested and validated our new OCT algorithm to calculate the lipid core longitudinal extension in a dedicated two-dimensional LCBI spread-out plot. In each coronary plaque, the following measurements were obtained with NIRS-IVUS: 1) minimum lumen area (MLA), 2) vessel area at MLA site, 3) plaque burden (%) at MLA site, 4) NIRS-defined lipid pool arch and 5) maximum LCBI measurement within a 4 mm length. The following OCT features were obtained: 1) the MLA cross section, 2) the minimum fibrous cap thickness (FCT) in presence of lipid components and measured as the average of three measurements obtained in the same cross-section and 3) maximum LCBI within a 4 mm length.
Results
Three lesions groups were identified according to the studied lesions: 1) culprit lesions in patients with acute coronary syndrome (ACS, n=16), 2) non-culprit lesions in patients with ACS (n=12) and 3) lesions in patients with stable angina (n=12). OCT conventional assessment showed for the culprit ACS plaques a trend for a larger lipid arc and a significant thinner FCT (p=0.028). Consistently, NIRS-IVUS showed for culprit ACS plaques a more complex anatomy. A strong trend for increased maximum LPBI in 4mm segments was found in the culprit ACS group, regardless of the adopted imaging modality, either NIRS-IVUS or automated OCT (p=0.184 and p=0.066, respectively, figure 1). A fair correlation was obtained for the maximum 4 mm LCBI measured by NIRS-IVUS and automated OCT (r=0.75). The sensitivity and specificity of automated OCT to detect significant LCBI, applying a validated 400 cut off were 90.5 and 84.2 respectively.
Conclusions
We developed an automated approach, comparable to NIRS, to assess OCT images that can provide a dedicated lipid plaque spread-out plot to address plaque vulnerability. The automated OCT software can promote and improve OCT clinical applications for the identification of patients at risk of hard events.

Abstract
Abstract
Background
Amyloidosis is a group of protein-folding disorders characterised by organ deposits, derived from one of several amyloidogenic precursor proteins. The involvement of coronary arteries has been previously described in amyloidosis, however the pattern of the disease in the coronaries is still unknown.
Purpose
The aim of this study is to characterise the pattern and severity of coronary artery lesions in cardiac amyloidosis.
Methods
We retrospectively compared patients with heart failure who tested positive (i.e. biopsy or gene tests – HF/CA+) against those that tested negative (HF/CA−) for cardiac amyloidosis. Groups were compared demographically and angiographically for qualitative and quantitative variables to determine patterns of involvement in the major epicardial coronary vessels.
Results
In total, 110 heart failure patients were included in the study, of whom 55 were HF/CA+ patients (88 lesions) and 55 were HF/CA− patients (66 lesions). Despite the advanced age in the HF/CA+, (74.53±11.02 vs 54.11±15.08; p=0.05), severe calcification was reported in HF/CA− group (4.5% vs to 0.0%; p=0.018). The HF/CA+ group also had fewer ostial lesions (3.4% vs. 15.15%, p=0.0095), reduced TIMI flow grade (83% vs 76%; p=0.21) and a higher TIMI frame count (30±12 Vs 27±11 frames; p=0.06). In the HF/CA+ group, compared to women, men had a significant number of tandem lesions (14.55% vs 0.0%, p=0.02). Men trended to have more ulcerations in comparison to women (9.09% vs 0.0%; p=0.15).
Conclusion
Overall, patients with HF/CA+ were older but found to have lesser calcified lesions, ostial involvement and a reduced anterograde blood flow. This is the first report outlining the coronary lesions in patients with HF/CA+.

Abstract
Abstract
Background
We previously demonstrated that high-dose (4 mg/day) compared with low-dose (1 mg/day) pitavastatin therapy significantly reduced cardiovascular events in Japanese patients with stable coronary artery disease in the Randomized Evaluation of Aggressive or Moderate Lipid Lowering Therapy with Pitavastatin in Coronary Artery Disease (REAL-CAD) study. However, little is known about whether the advantage of high-dose statins over low-dose statins is consistent among non-, mild, and moderate to severe chronic kidney disease (CKD) patients.
Purpose
The aim of this study was to clarify the effect of high-dose statins on cardiovascular events in Japanese patients with or without CKD.
Methods
The REAL-CAD study is a prospective, multicenter, randomized, open-label, blinded endpoint, physician-initiated superiority trial. In this sub-analysis of REAL-CAD study, patients were categorized into three groups according to estimated glomerular filtration rate (eGFR). Patients on hemodialysis were excluded in this study. The primary endpoint was a composite of cardiovascular death, non-fatal myocardial infarction (MI), non-fatal ischemic stroke, or unstable angina requiring emergency hospitalization. A secondary composite endpoint was defined as a composite of the primary endpoint event or clinically-indicated coronary revascularization excluding target-lesion revascularization.
Results
The total population of the REAL-CAD study was 12,413 patients. After exclusion of patients lacking eGFR data, the numbers of patients categorized into non-CKD (eGFR ≥60 mL/min/1.73m2), mild CKD (eGFR; 45–60), and moderate to severe CKD (eGFR <45) were 7,778 (64%), 3,176 (26%), and 1,164 (10%), respectively. The median follow-up period was 3.9 years. The baseline characteristics and medications were well balanced between the two groups in each CKD group. While high-dose compared to low-dose pitavastatin significantly reduced the primary endpoint in non-CKD patients, the effect was not observed in mild CKD and moderate to severe CKD patients (Figure 1). High-dose compared with low-dose pitavastatin did not significantly reduce the secondary composite endpoint in both mild and moderate to severe CKD patients as well. High-dose pitavastatin significantly reduced the risks of MI and any coronary revascularization in non-CKD patients, however, the effects were diminished in mild CKD and moderate to severe CKD patients. There was no significant difference between high-dose and low-dose pitavastatin treatment in the risk of all-cause death, cardiovascular death, ischemic stroke, or unstable angina requiring emergency hospitalization in patients with or without CKD.
Conclusion
Although high-dose pitavastatin therapy significantly reduced cardiovascular events in non-CKD patients with stable angina compared to low-dose pitavastatin, such beneficial effects had diminished in Japanese patients with mild or moderate to severe CKD patients.

Abstract
Abstract
Background
The diagnostic performance of 0-hour/1-hour algorithm using high-sensitivity cardiac troponin I (hsTnI) for non-ST-segment elevation myocardial infarction (NSTEMI) has not been evaluated in an Asian population.
Purpose
We aimed to prospectively validate the 0-hour/1-hour algorithm using hsTnI in a Japanese population.
Method
We enrolled 754 Japanese patients (mean age of 70 years, 395 men) presenting to our emergency department with symptoms suggestive of NSTEMI. The hsTnI concentration was measured using the Siemens ADVIA Centaur hsTnI assay at presentation and after 1 hour. Patients were divided into three groups according to the algorithm: hsTnI below 3 ng/L (only applicable if chest pain onset >3 hours) or below 6 ng/L and delta 1 hour below 3 ng/L were the “rule-out” group; hsTnI at least 120 ng/L or delta 1 hour at least 12 ng/L were in the “rule-in” group; the remaining patients were classified as the “observe” group. Based on the Fourth Universal Definition of Myocardial Infarction, the final diagnosis was adjudicated by 2 independent cardiologists using all available information, including coronary angiography, coronary computed tomography, and follow-up data. Safety of rule-out was quantified by the negative predictive value (NPV) for NSTEMI, accuracy of rule-in by the positive predictive value (PPV), and overall efficacy by the proportion of patients triaged towards rule-out or rule-in within 1 hour.
Results
Prevalence of NSTEMI was 6.5%. The safety of rule-out (NPV 100%), accuracy of rule-in (PPV 26%), and overall efficacy (54%) were shown in Figure.
Conclusion
The 0-hour/1-hour algorithm using hsTnI is very safe and effective in triaging Japanese patients with suspected NSTEMI.

Abstract
Abstract
Background
It has been reported that intravascular ultrasound (IVUS) guided PCI reduced a risk of major adverse cardiac event compared to conventional angiography guided PCI, while comparison between IVUS-guided and optical frequency domain imaging (OFDI)-guided PCI specifically in long-term clinical outcomes (>1 year) has been unexplored.
Purpose
We sought to compare imaging surrogates at 8 months and clinical outcomes beyond 1 year after drug-eluting stent implantation between IVUS and OFDI guidance.
Methods
The MISTIC-1 is a prospective, multi-centre, single-blinded, randomised-controlled, non-inferiority trial comparing OFDI-guided and IVUS-guided PCI using Biolimus A9 eluting Nobori stent. We enrolled patients with stable coronary artery disease who have symptoms or clinically relevant myocardial ischemia. Stent landing zones were selected in the most normal looking sites with largest lumen and without percentage plaque area >50% in IVUS group while without lipidic plaque of >2 quadrants or suggestive thin-cap fibroatheroma in OFDI group. Stent sizing was based on external elastic lamina (EEL) in IVUS group, while by taking 10% or 0.25mm larger than mean lumen diameter at reference sites in OFDI group. Stent optimisation with in-stent minimum lumen area ≥80% of the average lumen area at proximal and distal reference sites was encouraged in both groups. Primary efficacy endpoint is in-segment minimum lumen area (MLA) assessed by OFDI at 8 months. Secondary safety endpoint is a composite of cardiovascular death, target vessel myocardial infarction, or target lesion revascularisation. Based on the assumption that mean in-segment MLA at follow-up was 4.5mm2 with a standard deviation of 2.0mm2 in the control (IVUS) group and a non-inferiority limit of 1.2mm2 for OFDI group, sample size was estimated as 48 cases in each group with 5% type I error and 90% statistical power.
Results
Since June-2014 and August-2016, we prospectively enrolled 109 patients (mean age 70 years, male 78%) with 126 lesions. Baseline patient and lesion characteristics were well balanced and average nominal size and length of stent used did not differ between OFDI-guided and IVUS-guided PCI (3.0 and 19.1mm vs. 3.1 and 19.3mm, respectively). Post-procedural minimum stent area was 6.24mm2 in OFDI group and 6.72mm2 in IVUS group (p=0.20). At 8-month follow-up, in-segment MLA was 4.56mm2 in OFDI group and 4.13mm2 in IVUS group (P for non-inferiority <0.001). During the follow-up (median 4.5 years [1654 days]), incidence rates of major adverse cardiac event were comparable between the two groups (7.4% in OFDI group and 7.3% in IVUS group, hazard ratio 0.96, 95% CI 0.24–3.83, p=0.95). No definite or probable stent thrombosis were documented in both groups.
Conclusion
OFDI-guided PCI demonstrated comparable results in achieving satisfactory imaging surrogates as well as long-term clinical outcomes after newer generation DES implantation as compared to IVUS-guided PCI.

Abstract
Abstract
Background
Percutaneous Coronary Intervention (PCI) using the new generation drug-eluting stent (DES) has been extremely reduced target lesion revascularization (TLR) in recent years. However, a high incidence of non-target lesion-related cardiovascular events in patients undergoing PCI is an important problem to be solved. According to the previous findings, patients with vulnerable plaques particularly have a high recurrence of cardiovascular events. Little studies, however, has been done to examine the relationship between plaque characteristics on intravascular imaging in a target lesion and non-target lesion-related cardiovascular events.
Purpose
The main objective of this study is to investigate the five-year major adverse cardiac and cerebrovascular events (MACCE) of patients with lipid core abutting lumen (LCAL) on integrated backscatter intravascular ultrasound (IB-IVUS) in a target lesion undergoing PCI with current DES.
Methods and results
Between February 2010 and September 2013, in total 780 patients with ischemic heart disease undergoing PCI, 166 target lesions in 166 consecutive patients with non-ST segment elevation acute coronary syndrome (NSTE-ACS) and stable angina pectoris (SAP) undergoing IVUS-guided PCI were studied.
Plaque characteristics in all target lesions were analyzed by three-dimensional IB-IVUS system using the mechanical IVUS catheter. Our previous study has found that LCAL which is defined as a lipid pool directly in contact with the lumen visualizes the thin fibrous cap of less than 75μm on optical coherence tomography (OCT). On the basis of this data, LCAL at minimal lumen area (MLA) site was identified.
In total, 39 patients had lesions with LCAL at MLA site (LCAL(+)), and 127 patients had those without LCAL (LCAL(−)).
The primary endpoint was defined as MACCE, including cardiovascular death, non-fatal myocardial infarction, non-fatal stroke and non-TLR for the new lesion during a median follow up of five years. The MACCE occurred significantly higher in the LCAL(+) than in the LCAL(−) (38.5% vs. 17.3%; p<0.005). And the Kaplan-Meier estimates have shown that the cumulative incidence of MACCE was significantly higher in the LCAL(+) than in the LCAL(−) (log rank test, p=0.041). Additionally, after adjustment for confounders, gender, prior PCI and LCAL was the independent predictors for the MACCE of patients undergoing PCI with current DES.
Furthermore, after adding LCAL to a baseline model with established factors consisting of age, gender, diabetes mellitus, prior PCI and percentage lipid volume on IB-IVUS, the net reclassification (p<0.002) and integrated discrimination improvement (p<0.004) significantly improved compared to baseline model alone.
Conclusions
In this study, it has become clear that LCAL on IB-IVUS is likely to be a surrogate marker of MACCE in patients undergoing PCI with current DES.

Abstract
Abstract
Background
A silent cerebral event (SCE), detected by brain magnetic resonance imaging (MRI), is defined as an acute new brain lesion without clinically apparent neurological deficit, and is frequently observed after catheter ablation in atrial fibrillation (AF) patients. Although the small number of SCEs does not cause neurocognitive dysfunction, the greater volume and/or larger number of SCE lesions are reportedly related to neuropsychological decline; SCE incidence may be a surrogate marker for the potential thromboembolic risk. Thus, strategies to reduce SCEs would be beneficial. Uninterrupted oral anticoagulation strategy for peri-procedural period reportedly reduced the risk of SCEs, but the incidence hovers at 10% to 30%. We sought factors associated with SCEs during catheter ablation for AF in patients with peri-procedural uninterrupted oral anticoagulation (OAC) therapy.
Methods
AF patients undergoing catheter ablation were eligible (n=255). All patients took non-vitamin K antagonist oral anticoagulants (NOACs) or vitamin K antagonist (VKA) for peri-procedural OAC (>4 weeks) without interruption during the procedure. Brain MRI was performed within 2 days after the procedure to detect SCEs. Clinical characteristics and procedure-related parameters were compared between patients with and without SCEs.
Results
SCEs were detected in 59 patients (23%, SCE[+]) but not in 196 patients (77%, SCE[-]). Average age was higher in SCE[+] than SCE[-] (66±10 years vs. 62±12 years, p<0.05). Persistent AF prevalence, CHADS2/CHA2DS2-VASc scores, and serum NT-ProBNP levels increased in SCE[+] vs. SCE[-]. In transthoracic/transesophageal echocardiography, left-atrial dimension (LAD) was larger and AF rhythm/spontaneous echo contrast were more frequently observed in SCE[+] than SCE[-]. SCE[+] had lower initial activated clotting time (ACT) before unfractionated heparin (UFH) injection and longer time to reach optimal ACT (>300 sec) before trans-septal puncture than SCE [-]. In multivariate analysis, LAD, initial ACT before UFH injection, and time to reach optimal ACT were predictors for SCEs.
Conclusions
LAD and intra-procedural ACT kinetics affect SCEs during the procedure in patients with uninterrupted OAC for AF ablation. Shortening time to achieve optimal ACT during the procedure may reduce the risk of SCEs.

Abstract
Abstract
Background
Presepsin, a subtype of soluble CD14, is an inflammatory marker, which largely reflects monocyte activation. The association between presepsin levels and mortality in patients treated at medical cardiac intensive care units (CICUs) remains poorly known.
Objective
We aimed to understand the prognostic value of presepsin levels on admission to medical CICUs for mortality.
Methods
We prospectively studied 1636 heterogeneous patients (median age; 71 years) treated at medical (non-surgical) CICUs. Patients with stage 5 chronic kidney disease (estimated glomerular filtration rate [eGFR] <15 mL/min/1.73 m2) were excluded. Acute coronary syndrome was present in 46% of the patients, and acute decompensated heart failure in 36%. Upon admission, baseline plasma presepsin levels were measured. The primary endpoint was all-cause death.
Results
During a mean follow-up period of 44.6 months after admission, there were 323 (19.7%) deaths. Patients who died were older (median: 75 vs. 71 years, P<0.0001); had higher levels of presepsin (194 vs. 110 pg/mL, P<0.0001), B-type natriuretic peptide (BNP: 520 vs. 144 pg/mL, P<0.0001), high-sensitivity C-reactive protein (hsCRP: 4.7 vs. 2.0 mg/L, P<0.0001), and sequential organ failure assessment (SOFA) score (3 vs. 2, P<0.0001); and had lower levels of eGFR (55 vs. 69 mL/min/1.73m2, P<0.0001) and left ventricular ejection fraction (46% vs. 52%, P<0.0001) than those of the survivors. Multivariate Cox regression analyses revealed presepsin levels as independent predictors of all-cause deaths when assessed as either continuous variables (relative risk [RR] 3.33 per 10-fold increment; P<0.0001) or variables categorized according to quartiles (RR quartile 4 vs. 1, 3.60; P<0.0001). Quartiles of presepsin levels were significantly (P<0.0001) associated with increased risk of mortality (Figure). Adding presepsin levels to a baseline model that included established risk factors, BNP, and hsCRP further enhanced reclassification (P=0.009) and discrimination (P=0.0008) beyond that of the baseline model alone.
Conclusions
Circulating concentration of presepsin on admission may be a potent and independent predictor of mortality, and it may improve the risk stratification of patients admitted at medical CICUs.

Abstract
Background:Systemic lupus erythematosus (SLE) is a heterogeneous disease in which excessive inflammation, autoantibodies, and complement activation lead to multisystem tissue damage. Plasmacytoid dendritc cells (pDCs) play a central role in the pathogenesis of SLE through dysregulated type I IFN production, together with activated myeloid DCs (mDCs), amplifying vicious spiral of autoimmune disorders(1). Therefore, control of the aberrant DC activation may provide an alternative treatment strategy against SLE.Objectives:Mycophenolate mofetil (MMF), which has been used to treat lupus nephritis, specifically blocks proliferation of B and T lymphocytes by inhibition of inosine-5-monophosphate dehydrogenase (IMPDH). In addition, although there is evidence indicating the immunosuppressive effects of MMF on human monocyte-derived dendritic cells(2.3), there are no reports showing its effects on human blood DC subsets. Here we focused on the effects of MMF on the functions of the blood pDCs and mDCs.Methods:We isolated human blood DCs from healthy donors using cell sorting(4) and examined the function of mycophenolic acid (MPA), which is metabolic products of MMF, on DC subsets in response to TLR-ligands and serum from patients with active SLE. Written informed consent was obtained from all healthy adult donors and SLE patients.Results:We found that therapeutic plasma concentration range of MPA down-regulated expression of CD40, CD80 and CD86 dose-dependently on mDCs and pDCs without inducing apoptosis, in response to R848(TLR7/8 agonist) and CpG2216(TLR9 agonist), respectively. Of note, MPA profoundly suppressed IL-12 production and STAT4 expression in the mDCs and IFN-α production and IRF7 expression in the pDCs(Fig 1). We also obserbed inhibition of nuclear translocation of IRF-7 in pDCs treated with MPA by confocal microscopy(Fig 2). Furthermore,we identified that MPA had an inhibitory effect on SLE serum-induced IFN-α production by human PBMCs.Conclusion:Our data suggest that MMF can drive a wedge into the vicious spiral of autoimmune disorders through regulating the function of not only lymphocyte but also DC subsets. Thus, we unveiled a part mechanism of the therapeutic ability of MMF against SLE.References:[1]A Plasmacytoid Dendritic Cells-Type I Interferon Axis is Critically Implicated in the Pathogenesis of Systemic Lupus Erythematosus.

Abstract
Background:Rheumatoid arthritis (RA) is a common autoimmune disease. It is characterized by systemic synovitis with bone erosion and joint cartilage degradation(1). Production of autoantibody is important for autoimmune disease. Cytokines play crucial roles in its pathogenesis(2). SNP distribution varies between races. Few studies have examined SNP targeted at Japanese patients. The analysis of cytokine gene polymorphisms is important factor of pathophysiology and treatment.Objectives:This analysis was aimed to investigate the association between cytokine gene polymorphisms and autoantibody and therapeutic response in Japanese RA patients.Methods:This study subjects consisted of 100 RA patients and 50 healthy controls. We extracted data on patient sex, age, disease duration, rheumatoid factor (RF), anti cyclic citrullinated peptide (anti-CCP) antibody and therapeutic response including methotrexate (MTX) and biological DMARDs. Genomic DNA was isolated from peripheral blood, these were genotyped for TNFα, TGFβ1, IL-6, IL-10 and IFNγ polymorphisms. We analyzed these data using a chi-square test.Results:IL-10 (-819 C/T and -592 C/A) revealed that there were significant decrease in the frequency of IL-10 (-819) CC genotype and (-592) CC genotype as compared to controls in RA patients. Genotyping of IL-10 showed that there was significant decrease ACC/ACC genotype (Table 1).IFNγ (+874 A/T) revealed that there was significant decrease in the frequency of TT genotype as compared to controls (Table 1).No significant differences in TNFα, TGFβ1and IL-6 genotypes and alleles frequency were observed between RA patients and control.TGFβ1(+869 A/T) in patients with anti-CCP antibody positive revealed that there was significant decrease in the frequency of TT genotype as compared to patients with anti-CCP antibody negative (Table 2).No significant association between RF and any cytokine gene polymorphism.Analyzing cytokine gene polymorphisms could be useful for treatment with MTX and biological DMARDs.Table 1.Table 2.Conclusion:IL-10 (-819 C/T, -592 C/A) and IFNγ (+874 A/T) polymorphism might be related to RA in Japanese population. In addition, TGFβ1(+869 A/T) polymorphism might be associated with the production of anti-CCP antibody. These results suggest that the analyzing cytokine gene polymorphisms may offer promise as useful factors in the choice of treatment for Japanese RA patients.References:[1] Scott DL, Wolfe F, Huizinga TW.

Abstract
An 81-year-old man was transferred to our institution by ambulance because of poor feeding, general fatigue and slight disorientation lasting for a week. On arrival, he was awake and able to speak, however, his blood pressure was low at 61/43 mmHg in spite of his medical history of hypertension. His ECG showed abnormal Q waves and ST elevation in II, III, aVF leads. The echo exam detected severe hypokinesis in the left ventricular inferior wall and reduced ejection fraction at 30%. Pericardial effusion was not observed in the first echo exam. The patient was diagnosed as cardiogenic shock due to recent inferior myocardial infarction. Coronary angiography was performed, which detected total occlusion of mid right coronary artery, followed by a successful percutaneous coronary intervention (PCI) with a drug-eluting stent under the support of intra-aortic balloon pumping. Nevertheless, his blood pressure remained low and intravenous adrenaline administration was necessary during and even after PCI. To detect the cause of prolonged low blood pressure, echo was performed again immediately after PCI. The echo exam detected new findings: right ventricular posterior free wall was dissected and abnormal shunt flows were obviously observed from left ventricle to right atrium through the dissection cavity during systole. An urgent surgical repair was considered as the only option for his survival, however, his family did not accept it because the operation itself was too risky. On the next day of his admission, he passed away. Right ventricular free wall dissection is a very rare but fatal complication after inferior myocardial infarction, nevertheless, we could detect it by echocardiography with clearly recorded images.

Abstract
Background
One of the novel echocardiographic indices reflecting left ventricular (LV) diastolic filling is the combination of mitral annular peak systolic (s’) and early diastolic velocities (e’) with early transmitral peak flow velocity (E); E/(e’ x s’). This index is reported to be useful to predict a prognosis of heart failure patients regardless of their LV ejection fraction (LVEF).Purpose: The aim of this study was to examine whether or not E/(e’ x s’) could predict cardiac events in patients with acute coronary syndrome (ACS).Methods: We studies consecutive ACS patients hospitalized in our institution between December 2009 and February 2012. They underwent echo examination within 7 days after admission. By use of Doppler tissue imaging, e’ and s’ were respectively calculated by averaging the peak velocities measured at both septal and lateral mitral annulus in 4-chamber view. The exclusion criteria were as follows: atrial fibrillation, significant valvular diseases and inadequate echo images. Cardiac events were defined as re-hospitalization due to recurrent ACS and/or heart failure, and cardiac mortality.Results: In total, 168 patients were eligible for this study (mean age 67 ± 11 years, mean LVEF 51.7 ± 10.3 %). Median follow-up period was 22.5 months. During the follow-up, cardiac events occurred in 27 patients (16.1%). Between the patients with cardiac events and those without, there were significant differences in LV end-systolic volume (44.2 ± 29.1 vs 33.2 ± 13.6 ml, p < 0.05), LV mass index (122.4 ± 38.9 vs 107.5 ± 26.4 g/m², p < 0.05), left atrial volume index (31.7 ± 9.2 vs 27.6 ± 9.4 ml/m², p < 0.05), LVEF (45.7 ± 13.5 vs 52.9 ± 9.2 %, p < 0.05), s’ (5.1 ± 1.6 vs 7.1 ± 1.7 cm/sec, p < 0.001), e’ (4.8 ± 1.3 vs 6.0 ± 1.9 cm/sec, p < 0.05), E/e’ (16.4 ± 6.6 vs 12.5 ± 4.9, p < 0.05), E/(e’ x s’) (3.78 ± 2.52 vs 1.94 ± 1.08, p < 0.001), and serum B-type natriuretic peptide (334.7 ± 420.1 vs 113.8 ± 177.2 pg/ml, p < 0.05). While Cox proportional hazard multivariate analysis detected that E/(e’ x s’) and E/e’ were independent predictors of cardiac events, E/(e’ x s’) was more powerful than E/e’ (p = 0.0002 vs p = 0.0072). ROC analysis revealed that 2.35 of E/(e’ x s’) was the optimal cutoff values to predict cardiac events in ACS patients (AUC 0.79). Patients with E/(e’ x s’) <2.35 had significantly better prognosis than the rest (p < 0.0001, Log-rank; Figure)Conclusion: E/(e’ x s’) could be a useful echo marker to predict cardiac events in ACS patients.

Abstract
Background
It remains to be clarified whether clinical significance of left ventricular (LV) diastolic function differs depending on the severity of LV systolic dysfunction in patients with acute heart failure (AHF). The aim of this study was to examine the prognostic role of LV diastolic function in AHF patients with various systolic dysfunction.Methods: We studied consecutive hospitalized AHF patients with LV ejection fraction (LVEF) <50%. The exclusion criteria were as follows: atrial fibrillation, severe mitral regurgitation, and inadequate echo image quality. They underwent echocardiography on admission. The eligible patients (n = 289, 165 males, 76 ± 10 years) were divided into 4 groups based on LVEF and left atrial pressure (LAP) grade estimated as in the ESC guidelines: Group I (LVEF 40-49% (mildly reduced LVEF)/normal LAP, n = 28), II (mildly reduced EF/increased LAP, n = 38), III (LVEF <40% (severely reduced LVEF)/normal LAP, n = 110), and IV (severely reduced LVEF/increased LAP, n = 113). Cardiac death was examined up to 60 months.Results: In total, 58 patients (20%) died because of cardiac events during the follow-up (mean 20 ± 19 months). In patients with mildly reduced LVEF, Group I showed significantly less cardiac death ratio than II (n = 1 vs 10, Group I vs II, p = 0.03). On the other hand, in patients with severely reduced LVEF, there was no significant difference in cardiac death ratio between Group III and IV (n = 23 vs 24, Group III vs IV, p = 0.80). That is, LAP grade was a prognostic marker when the patients had mild LV systolic dysfunction, whereas it did not contribute to the prediction of cardiac mortality when patients showed severely reduced LV systolic function. Group I showed significantly better prognosis than those with severe LV systolic dysfunction regardless of LAP grade (Group III, IV) (Group I vs III, p = 0.04; Group I vs IV, p = 0.04).Conclusions: LV diastolic function may have a different clinical significance depending on the severity of LV systolic dysfunction in AHF patients.

Abstract
Abstract
Purposes
We examined how changes in left ventricular (LV) global longitudinal strain (GLS) were associated with prognosis in patients with preserved LV ejection fraction (LVEF) after congestive heart failure (HF) admission.
Methods
We studied 123 consecutive patients (age 70 ± 15 years, 55% male) who had been hospitalized due to congestive HF with preserved LVEF (> 50%). The exclusion criteria were atrial fibrillation and inadequate echo image quality for strain analyses. The patients underwent speckle-tracking echocardiography and measurement of plasma NT-ProBNP levels on the same day at the time of hospital admission as well as in the stable condition after discharge. Differences in GLS, LVEF and NT-ProBNP (delta GLS, LVEF and NT-ProBNP ; 2nd – 1st measurements) were calculated. The study end points were all-cause mortality and cardiac events.
Results
Mean periods of echo performance after hospitalization were 2 ±1days (1st echo) and 240 ± 289 days (2nd echo), respectively. During the follow-up (974 ± 626 days), 12 patients died and 25 patients were hospitalized because of HF worsening. In multivariate analysis, delta GLS and follow-up GLS were prognostic factors, whereas baseline and follow-up LVEF, NT-ProBNP, changes in LVEF and NT-ProBNP could not predict cardiac events. Delta GLS (p = 0.002) turned out to be the best independent prognosticator. Receiver operating characteristics analysis revealed that -0.6% of delta GLS was the optimal cut-off value to predict cardiac events and mortality (sensitivity 76%, specificity 67%, AUC 0.75). Kaplan-Meier analysis showed that patients with delta GLS more than -0.6% experienced significantly less cardiac events during the follow-up period (p < 0.0001, log-rank).
Conclusion
A change in LV GLS after congestive HF admission was a predictor of the prognosis in patients with preserved LVEF. It would be useful to check the changes in GLS in those with preserved LVEF after discharge.

Abstract
Abstract
Background
Global longitudinal strain (GLS) is an echocardiographic marker to detect subclinical left ventricular systolic dysfunction prior to the appearance of reduced left ventricular ejection fraction (LVEF). Reduced GLS identified in patients with maintenance hemodialysis (HD) has been reported to be a predictor of their higher mortality and cardiovascular events. On the other hand, pharmacological stress 13N-ammonia positron emission tomography (13N-NH3-PET) has been an established and reliable imaging modality to evaluate myocardial perfusion expressed as coronary flow reserve (CFR) or maximal stress myocardial blood flow (MBF). CFR and MBF are powerful parameters to detect coronary artery disease and to predict cardiovascular events and mortality. However, association between GLS and those myocardial perfusion parameters are not fully understood.
Purpose:The aim of this study was to evaluate the relationship between GLS and the myocardial perfusion parameters of 13N-NH3-PET in HD patients with preserved LVEF.
Methods
We studied 24 HD patients (mean age 67 years, 67% male) who underwent ATP stress 13N-NH3-PET as well as transthoracic echocardiography including 2-dimensional speckle tracking imaging for suspected ischemic heart disease. Exclusion criteria were as follows: LVEF <50%, moderate to severe valvular diseases, and atrial fibrillation. Myocardial perfusion abnormality (MPA) was defined as CFR <2.0 and/or stress MBF <2.0.
Results
Mean GLS in all patients was -16.2 ± 3.6%. The patients were divided into 2 groups based on GLS: patients with reduced GLS (<-16%) (Group A, N = 11) and those with preserved GLS (≧-16%) (Group B, N = 14). There were no significant differences between 2 groups in age, gender, body mass index, left ventricular mass index, and average E/e’. Nevertheless, Group A had significantly lower stress MBF than Group B (1.7 ± 0.41 vs 2.0 ± 0.33, p = 0.031). In addition, Group A showed more frequent MPA compared with Group B (81.8% vs 42.9%, p = 0.043). There was a moderate correlation between GLS and stress MBF (r = 0.62, p = 0.0012), whereas no significant correlation was noted between GLS and CFR (r = 0.079, p = 0.71).
Conclusion
Reduced GLS was significantly associated MPA. MPA may be one of the major contributors to the reduction in GLS in HD patients with preserved LVEF.

Abstract
Abstract
Background
The relation between very low on-treatment low-density lipoprotein cholesterol (LDL-C) level and the cardiovascular event risk is still unclear in patients receiving the same doses of statins.
Methods
From the REAL-CAD study comparing high-dose with low-dose pitavastatin therapy in Japanese patients with stable coronary artery disease, 11105 patients without reported non-adherence for the study drug were divided into 3 groups according to the on-treatment LDL-C level at 6-month (<70 mg/dL, 70–100 mg/dL, and ≥100 mg/dL; N=1016, N=3078, and N=1665 in the pitavastatin 1 mg/day stratum; N=2431, N=2524, and N=391 in the pitavastatin 4 mg/day stratum). Primary outcome measure was a composite of cardiovascular death, non-fatal myocardial infarction, non-fatal ischemic stroke, or unstable angina requiring emergent admission.
Results
In the pitavastatin 1 mg/day stratum, cumulative 4-year incidence of the primary outcome measure was not significantly different across the 3 groups (5.0%, 5.7%, and 5.2%, P=0.51), while in the 4 mg/day stratum, it was significantly higher in the LDL-C ≥100 mg/dL group than in other groups (4.5%, 3.4%, and 9.1%, P<0.001). The adjusted risks of the LDL-C <70 mg/dL group relative to the LDL-C 70–100 mg/dL group (reference) remained insignificant for the primary outcome measure in both 1 mg/day and 4 mg/day strata (HR 0.84, 95% CI 0.58–1.18, P=0.32, and HR 1.25, 95% CI 0.88–1.79, P=0.22). The adjusted risk of LDL-C ≥100 mg/dL group relative to the reference group was not significant for the primary outcome measure in the 1 mg/day stratum (HR 0.82, 95% CI 0.60–1.11, P=0.21), while it was highly significant in the 4 mg/day stratum (HR 3.32, 95% CI 2.08–5.17, P<0.001). In the on-treatment LDL-C ≥100 mg/dL group in the 4 mg/day stratum, LDL-C increased by 6.3 mg/dL from baseline to 6-month despite dose escalation of pitavastatin from 1 mg/day to 4 mg/day, suggesting the presence of unreported poor adherence in this small subgroup.
Adjusted Effects of On-treatment LDL-C
Conclusions
Very low on-treatment LDL-C level (<70 mg/dL) was not associated with lower cardiovascular event risk compared with moderately low on-treatment LDL-C level (70–100 mg/dL) in patients receiving the same doses of statins. Too much emphasis on the target LDL-C strategy might mislead the clinical practice.

Abstract
Abstract
Background
There is increasing evidence to use direct oral anticoagulants (DOACs) in atrial fibrillation (AF) ablation. Uninterrupted use of DOACs is recommended for peri-procedural anticoagulation; the ways of choosing and/or using DOACs depend on physicians' decisions and preferences. Uninterrupted dabigatran (DAB), a direct thrombin inhibitor, reportedly decreased the risk of major bleeding (MB) in AF ablation, compared to uninterrupted warfarin (NEJM 2017; 376:1627). Among DOACs, only regular-dose of DAB (150 mg b.i.d.), showed superiority to warfarin for preventing ischemic thromboembolism (TE) in patients with non-valvular AF, implicating the powerful anti-thrombotic agent. DAB may decrease the potential risk of procedure-related TE.
Purpose
To evaluate whether use of DAB on the day of AF ablation decreases the prevalence of silent cerebral ischemia (SCI) detected by magnetic resonance imaging (MRI).
Methods
414 AF patients on DOACs were enrolled and admitted on the day before AF ablation. Among 354 patients on factor Xa inhibitors (rivaroxaban, apixaban, and edoxaban), the original DOACs were switched to DAB (150 mg b.i.d.) on the day of the procedure in 172 patients (Group D); the treatment remained unchanged in 182 patients (Group non-D). In both groups, DOACs were continuously used throughout the procedure. After propensity-score matching, procedure-related parameters/events and the incidence of MRI-detected SCI were compared between Group D (n=134) and Group non-D (n=134). These parameters in patients originally taking DAB, used without interruption during the procedure (uninterrupted DAB, n=55), were also compared to Group D (n=55) after propensity-score matching.
Results
Baseline activated clotting time (ACT) before initial heparin injection was increased in Group D vs. Group-non-D (179±25* vs. 146±23 sec, *p<0.05 vs. Group non-D). The time to achieve optimal ACT (>300 sec) was shorter in Group D (34±29* vs. 43±32 min). The amounts of heparin needed to achieve optimal ACT and the total amount of heparin used during the procedure were unchanged between Group D and Group non-D. The incidence of SCI decreased in Group D (13.1%* vs. 21.9%), suggesting the potential anti-thrombotic efficacy of DAB. No MB or symptomatic TE events were observed in either group. Baseline ACT, the time to achieve ACT >300 sec, and the incidence of SCI in Group D were comparable to those in uninterrupted DAB (183±38 vs. 181±32 sec, 39±31 vs. 42±28 min, and 14.5% vs. 16.4%, respectively). No MB or symptomatic TE events were observed either in Group D or uninterrupted DAB.
Conclusions
Temporarily switching to DAB from the other DOACs and using it on the day of procedure enable us to achieve optimal ACT quickly and decrease the incidence of SCI, showing similar potential anti-thrombotic efficacy to uninterrupted DAB. Use of DAB on the day of AF ablation also benefits from the availability of its antidote in the case of MB during the procedure.

Abstract
Abstract
Background
Currently, invasive fractional flow reserve (FFR), has become a gold standard to select patients requiring revascularization. Coronary computed tomography angiography (CTA) -derived FFR (FFRCT/CT-FFR) can be used for the management of coronary artery disease, which would be a gatekeeper of invasive coronary angiography. In most of the previous report to evaluate the diagnostic performance of FFRCT/CT-FFR, FFRCT/CT-FFR value was measured at the same point as the invasive FFR. Clinically, FFRCT/CT-FFR should be measured without the information of invasive FFR. However, optimal measurement point for CT-FFR has not been established yet.
Purpose
To assess the optimal measurement point of CT-FFR in comparison with invasive FFR as a gold standard.
Methods
CTA images scanned at 70–99% of R-R interval with 320 slice CT were screened. In the de-novo lesions with invasive FFR data were included in this study. Since calcified lesions could affect CT-FFR value, severe calcified lesions on CTA were excluded from the analysis. The CT-FFR analysis was performed by 2 cardiologists blinded to the results of the invasive FFR using a standard desktop computer and dedicated software. CT-FFR values could be provided at any point from ostium of coronary artery to the distal with vessel diameter of 1.8mm. To determine the optimal point for measurement of CT-FFR, CT-FFR values were obtained at 3 points in each coronary artery; 1) at the same point as invasive FFR; 2) lowest CT-FFR at distal point of coronary artery; 3) at 2.0 cm distal to the lesion. The diagnostic performance at each point was compared with invasive FFR.
Results
Fifty vessels of 44 patients (average age 68 years, male were 32) were included. Average Agatston score was 279.4. There was significant correlation between CT-FFR at each point and invasive FFR. CT-FFR at the same point as invasive FFR showed the good correlation with invasive FFR (R=0.641, 95% CI= 0.041–0.127, p<0.0001). Compared to the lowest CT-FFR at distal (R=0.608, 95% CI= 0.069–0.160, p<0.0001), CT-FFR at 2.0 cm distal to the lesion (R=0.604, 95% CI= 0.007–0.061, p<0.0001) revealed better correlation with invasive FFR. Sensitivity, specificity, positive and negative predictive value at each point were 92.8 / 93.3 / 81.8; 75.0 / 57.1 / 94.2; 61.9 / 48.2 / 60.0; and 96.0 / 95.2 / 84.6, respectively. Diagnostic accuracy showed that CT-FFR at 2cm distal to the lesion (0.84) was similar to CT-FFR at the same point as invasive FFR (0.80), and it was better than far distal (0.68) to detect invasive FFR derived ischemia.
Conclusions
CT-FFR was feasible to detect invasive FFR derived ischemia at the same point.
CT-FFR at 2.0 cm distal to the lesion showed higher diagnostic performance compared with CT-FFR measured at the far distal. CT-FFR measurement at 2.0 cm distal to the lesion would be a optimal position clinically.

Abstract
Abstract
Background
The effect of statins on lowering high sensitivity C-reactive protein (hs-CRP) as well as low density lipoprotein cholesterol (LDL-C) has been associated with reduced risk for cardiovascular events in patients with elevated hs-CRP. However, it remains unclear whether this statin effect applies to low-risk patients with stable coronary artery disease (CAD). In this pre-specified sub-study within the REAL-CAD trial, we explored the association between achieved LDL-C/hs-CRP levels and cardiovascular events in Japanese patients with stable CAD who were treated with pitavastatin 1 mg or 4 mg/day.
Methods
The REAL-CAD trial randomly allocated 13,054 patients with stable CAD to pitavastatin 1 mg or 4 mg/day. LDL-C and hs-CRP were measured at baseline and at 6 months after randomization. We excluded those patients without 6-month data and those with endpoint events before 6 months (N=1915). The primary endpoint of the study was a composite of cardiovascular death, nonfatal myocardial infarction, nonfatal ischemic stroke, or unstable angina requiring emergency hospitalization. Outcomes were assessed by landmark analysis beyond 6 months among 4 groups that were configured based on LDL-C (median) and hs-CRP (median) targets: achieving neither target, achieving LDL-C target only, achieving hs-CRP target only, and achieving both targets. Data were adjusted for baseline characteristics including age, gender, diabetes and baseline values of LDL-C and hs-CRP.
Results
Median LDL-C and hs-CRP levels were 88 mg/dL and 0.52 mg/L at baseline and 80 mg/dL and 0.48 mg/L after 6 months, respectively. There was no correlation between the change in LDL-C and hs-CRP levels from baseline to 6 months (correlation coefficient: 0.009, P=0.331). Of the 11,677 patients included in the study, 25.1% (N=2799) achieved both LDL-C and hs-CRP targets, 25.3% (N=2282) met neither target, 24.8% (N=2765) met only the hs-CRP target, and 24.7% (N=2753) met only the LDL-C target. Risk of primary endpoint occurrence was significantly lower in those achieving either or both targets than in those meeting neither target (Figure A). In the subgroup analysis stratified by the randomized dose of pitavastatin, the risk for the primary endpoint was significantly lower in patients achieving both targets in both the 1mg and 4 mg arms, and in patients achieving only hs-CRP target in the 1 mg arm (Figure B, C).
Figure 1
Conclusions
In this subanalysis of the REAL-CAD trial, the hs-CRP lowering effect of pitavastatin was independent from LDL-C lowering. Lower achieved hs-CRP was associated with lower risk for cardiovascular events in Japanese patients with stable CAD.

Abstract
Abstract
Background
Conventional noninvasive approach using coronary CT angiography (CTA) focusing on only coronary artery lesions remains mismatch in identifying functional ischemia and determining indication for coronary revascularization.
Purpose
We aimed to assess the usefulness of CT-verified myocardial mass for identifying FFR-verified myocardial ischemia and determining the indication of coronary revascularization after FFR examination.
Methods
We examined 244 vessels with intermediate stenoses (50 to 90% stenosis visually on CTA) in 216 patients (mean age 69.2±9.2, 166 men) who underwent both coronary CTA and invasive FFR. In addition to coronary stenosis severity and plaque characteristics on visual, minimal lumen diameter (MLD), minimal lumen area (MLA), plaque volume, the entire myocardial volume of the target vessel (MTV) and that exposed to ischemia (FFR ≤0.80) (myocardial volume of ischemia: MVI) were evaluated. Additionally, therapeutic strategy after FFR was recorded.
Results
Of 244 vessels, myocardial ischemia (FFR ≤0.80) was shown in 99 (40.6%). MTV was larger in the patients with FFR-verified ischemia than those without (53.3±19.2 vs. 41.5±21.6, P<0.001); MLA, plaque burden (PB) and percentage of aggregated plaque volume (%APV) were also associated with ischemia. The area under the curves (AUCs) of MLA, PB, %APV, and MTV were 0.69, 0.67, 0.64, and 0.71, respectively. Addition of MTV to a model with coronary stenosis on visual, MLA, PB, and %APV improved C-index (from 0.72 to 0.79, P<0.01), net reclassification improvement (NRI) (0.71, P<0.01), and integrated discrimination improvement (IDI) (0.10, P<0.01). Of 99 vessels with FFR ≤0.80, MVI was larger in the vessels with early revascularization after FFR than those without (38.8 vs. 29.1, P=0.01).
Conclusions
The measurement of myocardial mass improves the diagnostic performance of coronary CTA for the identification of coronary arteries with FFR-verified ischemia. Furthermore, it is associated with therapeutic strategy for the diseased vessels after FFR examination.

Abstract
Abstract
Background
Hypoalbuminemia, a manifestation of protein-energy wasting or malnutrition, is commonly observed in patients with end-stage renal disease (ESRD), and is associated with chronic inflammation and increasing cardiovascular (CV) risk. Recently, C-reactive protein (CRP)/albumin ratio at discharge is reportedly a well-predictor of mortality in severe sepsis or cancer patients.
We investigated prognostic value of the CRP/albumin ratio at just starting haemodialysis (HD) therapy for CV morbidity and mortality in patients with ESRD.
Methods
A total of 1,548 ESRD patients were enrolled and were divided into quartiles according to CRP/albumin levels at initiation of HD; quartile 1 (Q1): <0.22, Q2: 0.23–0.54, Q3: 0.55–1.83 and Q4: >1.84. They were followed up for 10-year after starting HD therapy. Primary endpoint was CV events defined as hospitalization due to CV events such as cardiac disease, stroke and peripheral artery disease and CV death. We also evaluated the incremental value with C-index when CRP alone, albumin alone and the CRP/albumin ratio were added into a model with established risk factors.
Results
During follow-up period (median: 59 months), 512 cases experienced CV events (33.1%) including 165 cases of CV deaths (10.7%). Kaplan-Meier analysis shows that CV event-free survival rates for 10 years were 63.5%, 53.8%, 47.5% and 31.9% in Q1, Q2, Q3 and Q4, and that CV survival rates were 90.4%, 83.9%, 77.2% and 64.6% in Q1, Q2, Q3 and Q4, respectively (p<0.0001 in both). After adjustment for all baseline variables, elevated CRP/albumin ratio was identified as an independent predictor for CV events [hazard ratio (HR) 1.51, 95% confidence interval (CI) 1.11–2.07, p=0.0093 for Q2 vs. Q1, HR 1.79, 95% CI 1.33–2.42, p<0.0001 for Q3 vs. Q1and HR 2.27, 95% CI 1.70–3.07, p<0.0001 for Q4 vs. Q1, respectively]. As to CV mortality, similar results were obtained (HR 1.80, 95% CI 0.98–3.44, p=0.056 for Q2 vs. Q1, HR 2.56, 95% CI 1.45–4.71, p=0.0009 for Q3 vs. Q1 and HR 2.66, 95% CI 1.53–4.86, p=0.0004 for Q4 vs. Q1, respectively). Furthermore, adding the CRP/albumin ratio to a baseline model with established risk factors improved the C-index greater than that of CRP alone or albumin alone, respectively (0.715 from 0.692, p=0.0095 and from 0.683, p=0.0019)
Conclusion
The CRP/albumin ratio, which easily available from daily practice, could strongly stratify the risk of future CV morbidity and mortality in ESRD patients who need HD therapy.

Abstract
Abstract
Background
Elective percutaneous coronary intervention (PCI) using second generation drug-eluting stent (DES) has been dramatically reduced restenosis rate. Recently, it has been reported that plaque characterization in nontarget lesion is associated with cardio-vascular events in ischemic heart disease patients undergoing elective PCI. However, it is unclear whether plaque characterization in target lesion is predictor of MACEs (major adverse cardiac events) after elective PCI.
Purposes
The aim of this study is whether plaque characterization detected integrated-backscatter intravascular ultrasound (IB-IVUS) in the target lesion is associated with MACEs in patients with PCI after second generation DES implantation.
Methods and results
Of 700 patients with ischemic heart disease, 552 patients were excluded for chronic totally occlusion, severe calcification hindering precise intracoronary imaging, tortuous lesions, ostial or left main stem lesions and ST-elevated myocardial infarction patients. Finally, 148 consecutive patients who consented to repeated IB-IVUS prior to undergoing elective PCI were recruited in the study.Plaque characterization in target lesion was identified for three-dimensional IB-IVUS technology using the mechanical IVUS catheter (ViewIT, 40 MHz, 2.5 Fr; Terumo, Tokyo, Japan). The median of percentage lipid volume in all target lesions was 47.6%. Furthermore, lipid rich plaque (LRP) group was defined as the lesions consisting of percentage lipid volume greater than the median. And, non-lipid rich plaque (non-LRP) group was defined as the lesions consisting of percentage lipid volume less than the median. MACEs were defined as cardiovascular death, target vessel myocardial infarction, target lesion revascularization and stent thrombosis. The median of follow up period was 60 months. Of the 148 patients, 106 patients had stable angina pectoris. The remaining 42 patients are acute coronary syndrome (NSTE-ACS). 74 patients were classified LRP groups and 74 patients were non-LRP groups. No significant differences were observed between the two groups with respect to age, sex and coronary risk factors. While plaque and vessel volume were greater in the LRP group (216.9±116.3mm3, p<0.001) than non-LRP group (322.5±144.0mm3, p p<0.001). Remodeling index was greater in LRP group (1.02±0.18) than non-LRP group (0.93±0.18, p<0.003). Although MACEs were no significant differences between the two groups, the number of MACEs tend to be more in patients with LRP group (8.1±27.4%) than small lipid group (2.7±16.3, p<0.147). Especially, cardiac death tend to be more in LRP group (6.7±25.2% than non-LRP group (1.3±11.6, p<0.096).
Conclusions
In conclusion, lipid rich plaque detected by three dimensional IB-IVUS system in target lesion with patients undergoing elective PCI may be associated with clinical outcomes for five years after second generation DES implantation.

Abstract
Abstract
Background
Cardiac troponin (cTn) is the preferred biomarker for the diagnosis of acute myocardial infarction (AMI). Octogenarians who presented cTn positive AMI are not usually recruited in clinical trials. Therefore, their clinical characteristics and prognosis are rarely investigated.
Objective
To study the characteristics and prognosis in octogenarians who presented cTn positive AMI.
Methods and results
The Japanese registry of acute Myocardial INfarction diagnosed by Universal dEfiniTion (J-MINUET) is a prospective and multicenter registry. A total of 3,283 consecutive AMI patients who were diagnosed by cTn-based criteria were included. The patients were divided into non-octogenarians (n=2,593) and octogenarians (n=690). Compared with non- octogenarians, octogenarians showed significantly lower incidence of diabetes mellitus (37.6% and 31.9%, p=0.006) and dyslipidemia (53.6% and 45.6%, p<0.001), and significantly higher incidence of hypertension (64.1% and 75.3%, p<0.001) and chronic kidney disease (38.7% and 68.7%, p<0.001). Octogenarians showed significantly longer onset to door time (p<0.001) and longer door to device time (p<0.001). Though, compared with non-octogenarians, octogenarians showed lower peak CK (2,506 and 1,926, p<0.001), LVEF was significantly lower in octogenarians (54.6% and 52.6%, p=0.005). The presentation of AMI was different between the two group. The incidence of ST-segment elevation MI (STEMI) was 70.7% in non-octogenarians and 62.0% in octogenarians. Non-STEMI with CK elevation and without CK elevation were 16.2% and 13.1% in non- octogenarians, and 20.9% and 17.1% in octogenarians. In-hospital mortality was higher in octogenarians (4.7% and 13.2%, P<0.001). Especially, octogenarians with STEMI and non-STEMI with CK elevation showed the highest in-hospital mortality. And octogenarians without CK elevation showed similar in hospital mortality with non-octogenarians with STEMI (Figure).
Conclusions
J-MINUET showed the poor prognosis of octogenarians who were diagnosed as AMI based on cTn.

Abstract
Abstract
Background
Intravascular ultrasound (IVUS) and Optical Coherence Tomography (OCT) has been widely used in clinical settings. Although favorable results of imaging-guided percutaneous coronary intervention (PCI) compared with angio-guided PCI were observed in several studies, impacts of institutional-based usage frequency, about imaging-guided PCI, have not been well elucidated.
Methods
To elucidate the impact of imaging-guided PCI and the effects of frequency of its usage, we analyzed data of the Japanese registry of acute Myocardial INfarction diagnosed by Universal dEfiniTion (J-MINUET). This was a prospective and multicenter registry consisting of 3,283 AMI patients, who were hospitalized within 48 hours of onset from July 2012 to March 2014. Clinical follow-up data was obtained for 3 years. In this sub-study, a total of 2,788 patients who underwent urgent PCI having detailed procedural information were enrolled. We analyzed the differences of utilization rates of imaging-guided PCI among the participating institutions and the impacts for the clinical events. The participating institutions were divided into 3 groups by the frequency of IVUS usage: low frequency institutions: under 50%; moderate frequency institutions: 50% to 90%; and, high frequency institutions: over 90%.
Results
In this cohort registry, patients were enrolled from 28 institutions. The utilization rate of coronary imaging varied widely depending on each institution from 15.4% to 100% (mean 85.7%±24.3, median 97.4%). When the institutions were divided into 3 groups by the frequency of intravascular imaging usage, four low frequency institutions enrolled 295 patients, five moderate frequency institutions enrolled 624 patients, and 19 high frequency institutions enrolled 1,491 patients. Although the incidence of MACE (death, MI, stroke, cardiac failure, or revascularization for unstable angina) decreased stepwise (33.2%, 23.7%, and 19.7%) (gray bar in the Figure), the event rates of the imaging-guided PCI cases among the 3 groups were comparable (21.6%, 21.9%, and 19.6%) (white bar in the Figure). On the other hand, a gradual event reduction between the 3 groups was observed in the angio-guided PCI cases (black bar in the Figure). In comparison of MACE rate between imaging-guided and angio-guided PCI, there were statistically significant differences in the low frequency and moderate frequency institutions (p=0.001 and p=0.012, respectively). In contrast, comparable event rates were observed in the high frequency institutions (p=0.441).
MACE rate by imaging usage frequency
Conclusions
In Japanese ACS patients treated with imaging-guided PCI, better suppression of clinical events during 3-year was found in the institutions with the more frequent use of intravascular imaging, mainly due to stepwise event suppression in the cases of angio-guided PCI. On the other hand, the clinical benefit of coronary imaging was obtained independently of the frequency of use and its experience.

Abstract
Abstract
Background
Fulminant myocarditis is one of the fatal diseases for which effective management has not yet been established. Immunosuppressive therapy (IST) using corticosteroid has been actively applied to giant cell or eosinophilic myocarditis, there is no consensus on the efficacy of lymphocytic myocarditis, which is suspected of involving viral infection. Actually, IST for lymphocytic myocarditis is not recommended in the European Society of Cardiology guidelines, but in the Japanese Circulation Society guidelines, it is approved for use in refractory cases in the absence of curative therapy for myocarditis established.
Purpose
The purpose of this study was to explore the potential efficacy of immunosuppressive therapy on acute phase in fulminant lymphocytic myocarditis (FLM) requiring veno-arterial extracorporeal membranous oxygenation (VA-ECMO) support.
Method
We conducted CHANGE-PUMP study that was retrospectively enrolled 99 patients with fulminant myocarditis required VA-ECMO support in the Tokai area (central part of Japan) for the past 20 years. Lymphocytic myocarditis was defined by pathological category. Patients were divided into two groups depending on whether IST using corticosteroid was performed in the clinical course. Results: Sixty-six patients were pathologically diagnosed as fulminant myocarditis by endomyocardial biopsy, of which only 49 patients were FLM. IST were indicated in 8 (16%) out of 49 patients of FLM (IST group; n=8, non-IST group; n=41). Kaplan-Meier survival analysis showed a lower survival rate in the IST group than in the non-IST group (p=0.073). However, in all cases, based on our guidelines, IST was initiated after becoming refractory to MCS treatment.
Immunosupressive therapy and prognosis
Conclusion
In the retrospective analysis, biopsy-proven FLM patients with IST required VA-ECMO support had low survival rates. However, the timing of IST introduction was late and concerned. In the present era when advanced mechanical support appears and the survival rate of fulminant myocarditis is expected to improve, a multicenter prospective study is needed to establish an indication of IST in the acute phase of fulminant myocarditis.

Abstract
Abstract
Background
Fractional flow reserve (FFR) based strategy for coronary artery disease (CAD) is widely accepted. However, cardiac events could occur at deferred lesions after FFR. We previous reported that CT derived high risk plaque (HRP) and residual stenosis were the independent predictors of cardiac events.
Purpose
The purpose of this study was to investigate if plaque characteristics on CTA could predict cardiac events in deferred lesions after FFR.
Methods
We included 211 vessels of 193 patients who were deferred revascularization after CTA and invasive FFR. The presence of HRP and the stenosis grading on CTA were analyzed.
Results
Median follow-up period after CTA was 623 days (IQR 302–945). HRP and obstructive stenosis were detected in 58 (27.5%) and 87 (41.2%) lesions, respectively. Cardiac events were occurred in 10 lesions at 440±167 days in average (range: 150–770 days). Multivaliate cox hazard regression analysis revealed that HRP (HR8.01, p=0.0032) and obstructive stenosis with ≥70% (HR 34.93, p<0.0001) were the independent predictors of cardiac events after adjusted for age, sex, and FFR≤0.8. Of 21 lesions with both HRP and obstructive stenosis, 29% lesions resulted in cardiac events in 2 years.
Conclusions
Even in the deferred lesions by invasive FFR, lesions with HRP and obstructive stenosis showed high rate of cardiac events. These lesions should be treated with intensive medical therapy to prevent cardiac events.

Abstract
Abstract
Introduction
Sarcoidosis is a systemic inflammatory disease which can involve any organs. The reported prevalence of isolated cardiac sarcoidosis (CS) varies widely because of the lack of an agreed definition of isolated CS (iCS). ICS was newly defined in the new guidelines for CS by Japanese Circulation Society.
Purpose
We aimed to examine the diagnostic accuracy of 18F-FDG PET/CT and the ratio of iCS in the whole CS by reviewing the patients with suspected CS undergoing the whole-body and cardiac FDG PET/CT scans.
Methods
We retrospectively reviewed 74 consecutive patients undergoing 18F-FDG PET/CT from 2013 to 2018 (mean age 60±14 years, 37 male) without the initiation of corticosteroid. Myocardial FDG uptake in CS was defined as a “focal” or “focal on diffuse” pattern. Systemic sarcoidosis (sCS) and iCS were diagnosed according to guidelines for the diagnosis and treatment of CS by Japanese Circulation Society. In short, iCS was diagnosed clinically when no clinical findings of sarcoidosis in any other organs and FDG uptake in heart were shown in addition to the following three of four criteria: high-grade atrioventricular block or fatal ventricular arrhythmia, structural abnormality, left ventricular contractile dysfunction, and delayed Gadolinium enhancement of myocardium on MRI.
Results
Of 31 patients with extra-cardiac sarcoidosis, 10 already met the diagnostic criteria of sCS before undergoing 18F-FDG PET/CT and 11 was newly diagnosed as sCS after FDG PET/CT. Of the remaining 43 without extra-cardiac sarcoidosis, 18 had FDG uptake in heart. Of 18 with FDG uptake in heart, iCS was diagnosed in 7, and sCS in 3 with extra-cardiac uptake of FDG as well as myocardium. Finally, 24 and 7 patients met the criteria of sCS and iCS based on the guideline, respectively. The sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of FDG PET/CT for CS including sCS and iCS were 90, 87, 88, 85, and 92%, respectively.
Conclusion
The ratio of iCS on the basis of new guidelines for diagnosis and treatment of CS was 22% of the whole CS.

Abstract
Abstract
Background
The CHADS2score has mainly been used to predict the likelihood of cerebrovascular accidents in patients with atrial fibrillation. However, increasing attention is being paid to this scoring system for risk stratification of patients with coronary artery disease. We investigated the value of the CHADS2 score in predicting cardiovascular events in Japanese acute myocardial infarction (AMI) patients without atrial fibrillation.
Methods
To elucidate the prognostic value of CHADS2score in AMI patients, we analysed data of the Japanese registry of acute Myocardial INfarction diagnosed by Universal dEfiniTion (J-MINUET). This was a prospective and multicenter registry consisting of 3,283 AMI patients, who were hospitalized within 48-hours of onset from July 2012 to March 2014. We calculated the CHADS2 scores for 3,044 patients without clinical evidence of atrial fibrillation. The presence of heart failure was substituted by Killip classification>2 on admission. Clinical follow-up data was obtained for 3 years. In addition to the in-hospital mortality,we evaluated cardiovascular events, defined as all cause deathor non-fatal MI during 3-year follow up periods.
Results
In this study, enrolled patients were classified into low- (point 0–1), intermediate- (point 2–3), and high-score (point 4–6) groups by calculating CHADS2 score. Overall patients with low, intermediate and high score were divided into 1,395, 1,393 and 256 patients, respectively. In-hospital mortality among low, intermediate, and high score groups were 2.8%, 7.4% and 14.8%, respectively (P<0.001). The incidence of cardiovascular eventsamong low, intermediate, and high score groups were 7.8%, 16.3%, 29.3%, respectively (P<0.001). Kaplan-Meier analysis showed a significant difference between the groups (Figure). The event rates were significantly higher in both high score and intermediate score group than in low score group (P<0.001). Multivariate Cox hazard analysis identified CHADS2 score (per 1 point) as an independent predictor of cardiovascular events in addition to chronic kidney disease and lower body mass index. (hazard ratio, 1.344; 95% CI, 1.239–1.459; P<0.001). Among the factors constituting CHADS2 score, heart failure and age were identified as independent predictors for in-hospital mortality. With respect to the cardiovascular event during 3 years, heart failure, age, and previous stroke were revealed as significant independent predictors.
Conclusion
This large cohort study indicated that the CHADS2 score is useful for the prediction of in-hospital mortality and the cardiovascular events during 3-year follow up in Japanese AMI patients without atrial fibrillation.

Abstract
Abstract
Background
Presepsin, a subtype of soluble CD14, is an inflammatory marker, which largely reflects monocytic activation. Presepsin appears to be an accurate diagnostic marker of sepsis, but its clinical significance remains unclear in cardiovascular disease.
Purpose
This prospective study aimed to investigate the predictive value of plasma presepsin levels on admission to medical (non-surgical) cardiac intensive care units (MCICUs) for short-term mortality.
Methods
We examined 1560 patients hospitalized in MCICUs and measured the baseline plasma presepsin levels at admission.
Results
Acute coronary syndrome was present in 46% of the patients, and acute decompensated heart failure in 36%. Before MCICUs admission, emergent coronary angiography or percutaneous coronary intervention was performed in 36%, mechanical ventilation was required for respiratory insufficiency in 2.1%, and intraaortic balloon pumps were needed for hemodynamic instability in 8.9%. During 6 months after admission, there were 113 (7.2%) deaths. Patients who died were older (median: 77 vs. 71 years, P<0.0001); had higher levels of presepsin (263 vs. 119 pg/mL, P<0.0001), B-type natriuretic peptide (BNP: 696 vs. 186 pg/mL, P<0.0001), high-sensitivity troponin T (hsTnT: 81 vs. 47 pg/mL, P=0.004), and high-sensitivity C-reactive protein (13.8 vs. 2.2 mg/L, P<0.0001); and had lower levels of estimated glomerular filtration rate (50 vs. 65 mL/min/1.73m2, P<0.0001) and left ventricular ejection fraction (43% vs. 51%, P<0.0001) than those of the survivors. In the multivariate Cox regression analysis, higher levels of presepsin (P=0.0002), BNP (P=0.04), and hsTnT (P=0.009) were all independent predictors of 6-month deaths. Quartiles of presepsin levels were associated with higher mortality rates within 6 months after admission (Table). Adding presepsin levels to a baseline model that included established risk factors, BNP, and hsTnT further enhanced reclassification (P=0.004) and discrimination (P=0.003) beyond that of the baseline model.
Mortality rates according to presepsin Presepsin quartile 1st 2nd 3rd 4th P value ≤80 pg/mL 81–124 pg/mL 125–232 pg/mL >232 pg/mL 1-month mortality 0.8% 2.0% 3.3% 8.0% <0.0001 6-month mortality 0.8% 3.8% 8.2% 16.3% <0.0001
Conclusions
Presepsin levels at admission could improve the prediction of short-term mortality in patients hospitalized at MCICUs.

Abstract
Abstract
Background
Thrombolysis in Myocardial Infarction (TIMI) Risk Score for Secondary Prevention and CREDO-Kyoto Thrombotic Risk Score are contemporary secondary prevention risk scoring systems. However, these scoring systems have not been validated in other populations.
Purpose
The aim of this study was to validate of the TIMI Risk Score for Secondary Prevention and CREDO-Kyoto Thrombotic Risk Score in patients in the early phase of acute myocardial infarction (AMI).
Methods
The Japanese registry of acute Myocardial INfarction diagnosed by Universal dEfiniTion (J-MINUET) is a prospective multicenter registry conducted in 28 Japanese medical institutions. We enrolled 3,283 consecutive patients with AMI who were admitted to participating institutions within 48 hours of symptom onset between July 2012 and May 2014. Among them, 3,070 patients were included in this study after excluding 213 patients who died in the hospital. Clinical follow-up data were obtained up to 3 years. The primary endpoint was a composite of all-cause death, non-fatal MI and non-fatal stroke. The patients were stratified by the TIMI Risk Score for Secondary Prevention and CREDO-Kyoto Thrombotic Risk Score.
Results
At the 3-year follow-up, the primary endpoint had occurred in 337 patients (11.0%). All-cause death, non-fatal MI and non-fatal stroke had occurred in 177 (5.8%), 80 (2.6%) and 80 (2.6%) patients, respectively. TIMI Risk Score for Secondary Prevention and CREDO-Kyoto Thrombotic Risk Score showed a graded association with the composite of all-cause death, non-fatal MI and non-fatal stroke at 3 years in the J-MINUET population (Figure).
Validation of atherothrombotic risk
Conclusions
TIMI Risk Score for Secondary Prevention and CREDO-Kyoto Thrombotic Risk Score were shown to be applicable to the patients in the early phase of AMI.

Abstract
Sensing self-nucleic acids through toll-like receptors in plasmacytoid dendritic cells (pDCs), and the dysregulated type I IFN production, represent pathogenic events in the development of the autoimmune responses in systemic lupus erythematosus (SLE). Production of high-mobility group box-1 protein (HMGB1) promotes type I IFN response in pDCs. To better understand the active pathogenic mechanism of SLE, we measured serum levels of HMGB1, thrombomodulin, and cytokines (IL-1β, IL-2, IL-4, IL-5, IL-6, IL-10, IL-13, IL-17A, IL-17F, IFNα, IFNγ, TNFα) in 35 patients with SLE. Serum HMGB1 and IFNα were significantly higher in patients with active SLE (SLE Disease Activity Index (SLEDAI) score ≥ 6) compared with healthy donors or patients with inactive SLE. Furthermore, the HMGB1 levels were significantly correlated with IFNα levels. By qualitative analysis, the detection of serum IFNα or HMGB1 suggests active SLE and the presence of SLE-related arthritis, fever, and urinary abnormality out of SLEDAI manifestations. Collectively, HMGB1 and IFNα levels are biomarkers reflecting disease activity, and qualitative analysis of IFNα or HMGB1 is a useful screening test to estimate SLE severity and manifestations. Our results suggest the clinical significance of type I IFNs and HMGB1 as key molecules promoting the autoimmune process in SLE.

Abstract
An increased platelet count is often observed in lung cancer patients. Whether and how the platelets affect cancer progression have yet to be established. The aim of the study was to investigate the involvement of the platelet count and mean platelet volume (MPV) in the prognosis and progression of lung cancer patients. This retrospective study included 146 patients with newly diagnosed primary lung cancer. The platelet count and MPV were measured before invasive diagnostic procedures and treatment. These platelet indices, overall survival of the patients, and tumor metastases for each organ were analyzed. On Kaplan-Meier survival analysis, the overall survivals of patients with platelet counts ≤ 244.0 × 109/L or MPV > 9.7 fL were longer than those of patients with platelet counts > 244.0 × 109/L or MPV ≤ 9.7 fL. Cox regression analysis showed that poor performance status, increased platelet count, and increased C-reactive protein were independent prognostic factors. The platelet indices were associated with metastases to bone, soft tissue, and lymph node, in addition to malignant pleural effusion. Increased platelet count and decreased MPV were unfavorable prognostic factors for patients with lung cancer, and they were involved in bone, soft tissue, and lymph node metastases and malignant pleural effusion.

Abstract
Abstract
Background: In recent years, anti-PD-1 antibody, an immune checkpoint inhibitor, has been developed for the treatment of various types of cancer, including breast cancer. Synergistic effects of nivolumab, paclitaxel and bevacizumab are expected, based on various preclinical data, when these drugs are administered in combination. A biomarker study is ongoing to evaluate the immune status of patients participating in the NEWBEAT trial, which is a phase II trial of nivolumab + paclitaxel + bevacizumab therapy as first-line treatment for patients with metastatic or recurrent HER2-negative breast cancer. Methods: HER2-negative breast cancer patients from the WJOG9917B (NEWBEAT) trial are enrolled in this biomarker study. To explore new biomarkers for combined treatment of breast cancer with immune-checkpoint inhibitors and anti-vascular endothelial growth factor antibodies, we propose to conduct multicolor immunohistochemistry (IHC) assays for immunomonitoring of the intra-tumor environment, such as the expressions of PD-L1, CD4 and CD8. Blood samples are collected before the start of treatment and at four time-points during the treatment, to determine, using a multicolor flow cytometry panel, the numbers of circulating immunosuppressive cells, such as regulatory T cells, myeloid-derived suppressor cells and tumor-associated macrophages (M2). In the NEWBEAT trial, patients receive nivolumab 240 mg/body on days 1 and 15, paclitaxel 90 mg/m2 on days 1, 8 and 15, and bevacizumab 10 mg/kg on days 1 and 15 every 4 weeks until disease progression. The primary endpoint is the objective response rate, and the key secondary endpoints include progression-free survival, overall survival, and toxicity of the protocol treatment. A total of 51 patients will be enrolled and the enrollment period will be one year. This trial opened to accrual in February 2018. Clinical trial registry number: UMIN000029590
