Abstract
PURPOSE Dedifferentiated low-grade osteosarcomas, which are considered high grade malignancies, can arise from the dedifferentiation of parosteal and low-grade osteosarcomas. Usually, localized dedifferentiated low-grade osteosarcomas are treated by wide resection, and the efficacy of adjuvant chemotherapy is controversial. We conducted a systematic review of studies that investigated the rates of mortality and significant events, such as recurrence and metastases, in localized dedifferentiated low-grade osteosarcoma patients who received wide resection only and in those who received wide resection and (neo-)adjuvant chemotherapy. METHODS We identified 712 studies through systematic searches of Embase, PubMed, and the Cochrane Central Register of Controlled Trials databases. Of those studies, seven were included in this review and none were randomized controlled trials. In the seven studies, 114 localized dedifferentiated low-grade osteosarcoma patients were examined. RESULTS Mortality rates of the resection plus chemotherapy (R + C) and the resection only (Ronly) groups were 20.3% and 11.4%, respectively [overall pooled odds ratio, 1.59 (P = 0.662); heterogeneity I2, 0%]. The local recurrence or distant metastasis rate in the R + C group was 36.7% and that in the Ronly group was 28.6% [overall pooled odds ratio, 1.37 (P = 0.484); heterogeneity I2 was 0%]. CONCLUSIONS Results show a limited efficacy of adjuvant chemotherapy for localized dedifferentiated low-grade osteosarcoma. However, because this was a systematic review of retrospective studies that examined a small number of patients, future randomized controlled trials are needed.

Abstract
BACKGROUND Sodium-glucose co-transporter-2 (SGLT2) inhibitors reduce progression of chronic kidney disease and the risk of cardiovascular morbidity and mortality in a wide range of patients. However, their effects on kidney disease progression in some patients with chronic kidney disease are unclear because few clinical kidney outcomes occurred among such patients in the completed trials. In particular, some guidelines stratify their level of recommendation about who should be treated with SGLT2 inhibitors based on diabetes status and albuminuria. We aimed to assess the effects of empagliflozin on progression of chronic kidney disease both overall and among specific types of participants in the EMPA-KIDNEY trial. METHODS EMPA-KIDNEY, a randomised, controlled, phase 3 trial, was conducted at 241 centres in eight countries (Canada, China, Germany, Italy, Japan, Malaysia, the UK, and the USA), and included individuals aged 18 years or older with an estimated glomerular filtration rate (eGFR) of 20 to less than 45 mL/min per 1·73 m2, or with an eGFR of 45 to less than 90 mL/min per 1·73 m2 with a urinary albumin-to-creatinine ratio (uACR) of 200 mg/g or higher. We explored the effects of 10 mg oral empagliflozin once daily versus placebo on the annualised rate of change in estimated glomerular filtration rate (eGFR slope), a tertiary outcome. We studied the acute slope (from randomisation to 2 months) and chronic slope (from 2 months onwards) separately, using shared parameter models to estimate the latter. Analyses were done in all randomly assigned participants by intention to treat. EMPA-KIDNEY is registered at ClinicalTrials.gov, NCT03594110. FINDINGS Between May 15, 2019, and April 16, 2021, 6609 participants were randomly assigned and then followed up for a median of 2·0 years (IQR 1·5-2·4). Prespecified subgroups of eGFR included 2282 (34·5%) participants with an eGFR of less than 30 mL/min per 1·73 m2, 2928 (44·3%) with an eGFR of 30 to less than 45 mL/min per 1·73 m2, and 1399 (21·2%) with an eGFR 45 mL/min per 1·73 m2 or higher. Prespecified subgroups of uACR included 1328 (20·1%) with a uACR of less than 30 mg/g, 1864 (28·2%) with a uACR of 30 to 300 mg/g, and 3417 (51·7%) with a uACR of more than 300 mg/g. Overall, allocation to empagliflozin caused an acute 2·12 mL/min per 1·73 m2 (95% CI 1·83-2·41) reduction in eGFR, equivalent to a 6% (5-6) dip in the first 2 months. After this, it halved the chronic slope from -2·75 to -1·37 mL/min per 1·73 m2 per year (relative difference 50%, 95% CI 42-58). The absolute and relative benefits of empagliflozin on the magnitude of the chronic slope varied significantly depending on diabetes status and baseline levels of eGFR and uACR. In particular, the absolute difference in chronic slopes was lower in patients with lower baseline uACR, but because this group progressed more slowly than those with higher uACR, this translated to a larger relative difference in chronic slopes in this group (86% [36-136] reduction in the chronic slope among those with baseline uACR <30 mg/g compared with a 29% [19-38] reduction for those with baseline uACR ≥2000 mg/g; ptrend<0·0001). INTERPRETATION Empagliflozin slowed the rate of progression of chronic kidney disease among all types of participant in the EMPA-KIDNEY trial, including those with little albuminuria. Albuminuria alone should not be used to determine whether to treat with an SGLT2 inhibitor. FUNDING Boehringer Ingelheim and Eli Lilly.

Abstract
BACKGROUND sFrailty affects short-term outcomes after liver resection in elderly patients. However, frailty's effects on long-term outcomes after liver resection in elderly patients with hepatocellular carcinoma (HCC) are unknown. METHODS This prospective, single-center study included 81 independently living patients aged ≥65 years scheduled to undergo liver resection for initial HCC. Frailty was evaluated according to the Kihon Checklist, a phenotypic frailty index." We investigated and compared postoperative long-term outcomes after liver resection between patients with and without frailty. RESULTS Of the 81 patients, 25 (30.9%) were frail. The proportion of patients with cirrhosis, high serum alpha-fetoprotein level (≥200 ng/mL), and poorly differentiated HCC was higher in the frail group than in the nonfrail group (n = 56). Among the patients with postoperative recurrence, the incidence of extrahepatic recurrence was higher in the frail group than in the nonfrail group (30.8% vs. 3.6%, P = 0.028). Moreover, the proportion of patients who underwent repeat liver resection and ablation for recurrence who met the Milan criteria tended to be lower in the frail group than in the nonfrail group. Although there was no difference in disease-free survival between the two groups, the overall survival rate in the frail group was significantly worse than that in the nonfrail group (5-year overall survival: 42.7% vs. 77.2%, P = 0.005). Results of the multivariate analysis indicated that frailty and blood loss were independent prognostic factors for postoperative survival. CONCLUSION Frailty is associated with unfavorable long-term outcomes after liver resection in elderly patients with HCC.

Abstract
BACKGROUND The EMPA-KIDNEY trial showed that empagliflozin reduced the risk of the primary composite outcome of kidney disease progression or cardiovascular death in patients with chronic kidney disease mainly through slowing progression. We aimed to assess how effects of empagliflozin might differ by primary kidney disease across its broad population. METHODS EMPA-KIDNEY, a randomised, controlled, phase 3 trial, was conducted at 241 centres in eight countries (Canada, China, Germany, Italy, Japan, Malaysia, the UK, and the USA). Patients were eligible if their estimated glomerular filtration rate (eGFR) was 20 to less than 45 mL/min per 1·73 m2, or 45 to less than 90 mL/min per 1·73 m2 with a urinary albumin-to-creatinine ratio (uACR) of 200 mg/g or higher at screening. They were randomly assigned (1:1) to 10 mg oral empagliflozin once daily or matching placebo. Effects on kidney disease progression (defined as a sustained ≥40% eGFR decline from randomisation, end-stage kidney disease, a sustained eGFR below 10 mL/min per 1·73 m2, or death from kidney failure) were assessed using prespecified Cox models, and eGFR slope analyses used shared parameter models. Subgroup comparisons were performed by including relevant interaction terms in models. EMPA-KIDNEY is registered with ClinicalTrials.gov, NCT03594110. FINDINGS Between May 15, 2019, and April 16, 2021, 6609 participants were randomly assigned and followed up for a median of 2·0 years (IQR 1·5-2·4). Prespecified subgroupings by primary kidney disease included 2057 (31·1%) participants with diabetic kidney disease, 1669 (25·3%) with glomerular disease, 1445 (21·9%) with hypertensive or renovascular disease, and 1438 (21·8%) with other or unknown causes. Kidney disease progression occurred in 384 (11·6%) of 3304 patients in the empagliflozin group and 504 (15·2%) of 3305 patients in the placebo group (hazard ratio 0·71 [95% CI 0·62-0·81]), with no evidence that the relative effect size varied significantly by primary kidney disease (pheterogeneity=0·62). The between-group difference in chronic eGFR slopes (ie, from 2 months to final follow-up) was 1·37 mL/min per 1·73 m2 per year (95% CI 1·16-1·59), representing a 50% (42-58) reduction in the rate of chronic eGFR decline. This relative effect of empagliflozin on chronic eGFR slope was similar in analyses by different primary kidney diseases, including in explorations by type of glomerular disease and diabetes (p values for heterogeneity all >0·1). INTERPRETATION In a broad range of patients with chronic kidney disease at risk of progression, including a wide range of non-diabetic causes of chronic kidney disease, empagliflozin reduced risk of kidney disease progression. Relative effect sizes were broadly similar irrespective of the cause of primary kidney disease, suggesting that SGLT2 inhibitors should be part of a standard of care to minimise risk of kidney failure in chronic kidney disease.

Abstract
OBJECTIVE We aimed to assess the results of posterior leaflet augmentation with an autologous pericardial patch in atrial functional mitral regurgitation. METHODS Data of 16 patients with atrial functional mitral regurgitation who underwent posterior leaflet patch augmentation for mitral valve repair were retrospectively analyzed. This procedure was applied to a short posterior leaflet with a height of < 10 mm in P2. The median age was 72.5 [67.8-78.3] years. Preoperative New York Heart Association functional class was II in 7 (43.8%) and III or IV in 9 (56.2%) patients. Mitral regurgitation was moderate in 2 (12.5%) and severe in 14 (87.5%) patients. RESULTS Operative mortality occurred in 1 (6.2%) patient due to cerebral infarction. One patient required valve replacement because of patch perforation early after operation. Mitral regurgitation was reduced to less than mild in 15 (93.8%) patients and less than trivial in 11 (68.8%) patients (P < 0.01) postoperatively. As for mid-term results, New York Heart Association functional class improved to I or II in 12 (75%) patients (P < 0.01). Two cases of thrombotic complication were observed. Remote recurrent regurgitation occurred in one case due to small patch size. The 3-year free rate of valve-related morbidity and regurgitation recurrence was 65.6% and 87.1%, respectively. The 5-year survival rate was 93.8%. CONCLUSIONS Pericardial patch augmentation in atrial functional mitral regurgitation leads to good survival and mitral regurgitation recurrence-free rates. Steady anticoagulation and the use of larger patches would be necessary to reduce thrombotic complications and recurrent MR.

Abstract
Aim Coronavirus disease (COVID-19) spread worldwide, and was declared as a pandemic by the World Health Organization. Despite numerous studies in the last few years, the factors associated with the outcomes of patients with COVID-19 requiring mechanical ventilation remain unclear. The prediction of ventilator weaning and mortality using the data obtained at the time of intubation could be beneficial for establishing appropriate treatment strategies and obtaining informed consent. In this study, we aimed to clarify the association between patient information at the time of intubation and the outcomes of intubated COVID-19 patients. Methods This retrospective observational study used single-center data from patients with COVID-19. Patients with COVID-19 who were admitted to Osaka Metropolitan University Hospital from April 1, 2020, to March 31, 2022, and under mechanical ventilation were included. The main outcome was defined as the factors related to ventilator weaning; a multivariate analysis was carried out to evaluate the association between patient information at the time of intubation and the outcome. Results In total, 146 patients were included in this study. The factors significantly associated with ventilator weaning were age (65-74 years old, adjusted odds ratio [OR], 0.168; 75 years and older, adjusted OR, 0.121), vaccination history (adjusted OR, 5.655), and Sequential Organ Failure Assessment (SOFA) respiration score (adjusted OR, 0.007) at the time of intubation. Conclusion Age, SOFA respiration score, and COVID-19 vaccination history at the time of intubation could be associated with outcomes in patients with COVID-19 requiring mechanical ventilation.

Abstract
PURPOSE This study aimed to elucidate the geometric parameters of the aortomitral (AM) complex affecting postoperative cardiovascular events (CVEs) in patients with atrial functional mitral regurgitation (MR). METHODS From October 2008 to August 2018, we performed mitral and tricuspid valve repairs in 58 patients with atrial functional MR. We examined the determinants of CVEs using preoperative and postoperative echocardiographic data. Furthermore, we analyzed the effect of left atrial (LA) plication on AM geometries after surgery. The follow-up period ranged from 56 to 3283 days (median, 1073 days). RESULTS All patients underwent mitral and tricuspid annuloplasty. Seventeen patients (29%) underwent additional LA plication. The AM angle was narrowed after surgery in patients with CVEs (115° ± 6.8° to 106° ± 4.2°, p = .00336), whereas it widened in patients without CVEs (115° ± 7.4° to 118° ± 8.4°, p = .0278). The postoperative AM angle was an independent predictor of postoperative CVEs (p = .000829). LA plication was not a predictor of CVEs; however, it was a predictor of the obtuse postoperative AM angle (p = .0071). CONCLUSIONS Our results suggest that a narrow postoperative AM angle is an independent predictor of postoperative CVEs. Additional LA plication reduces the sharpening of the AM angle, which may prevent CVEs after mitral valve repair for atrial functional MR.

Abstract
Background Data on prophylactic anticoagulation are important in understanding the current issues, unmet needs, and optimal management of Japanese COVID-19 patients. Objectives This study aimed to investigate the clinical management strategies for prophylactic anticoagulation of COVID-19 patients in Japan. Methods The CLOT-COVID study was a multicenter observational study that enrolled 2,894 consecutive hospitalized patients with COVID-19. The study population consisted of 2,889 patients (after excluding 5 patients with missing data); it was divided into 2 groups: patients with pharmacological thromboprophylaxis (n = 1,240) and those without (n = 1,649). Furthermore, we evaluated the 1,233 patients who received prophylactic anticoagulation-excluding 7 patients who could not be classified based on the intensity of their anticoagulants-who were then divided into 2 groups: patients receiving prophylactic anticoagulant doses (n = 889) and therapeutic anticoagulant doses (n = 344). Results The most common pharmacological thromboprophylaxis anticoagulant was unfractionated heparin (68.2%). The severity of COVID-19 at admission was a predictor of the implementation of pharmacological thromboprophylaxis in the multivariable analysis (moderate vs mild: OR: 16.6; 95% CI:13.2-21.0; P < 0.001, severe vs mild: OR: 342.6, 95% CI: 107.7-1090.2; P < 0.001). It was also a predictor of the usage of anticoagulants of therapeutic doses in the multivariable analysis (moderate vs mild: OR: 2.10; 95% CI: 1.46-3.02; P < 0.001, severe vs mild: OR: 5.96; 95% CI: 3.91-9.09; P < 0.001). Conclusions In the current real-world Japanese registry, pharmacological thromboprophylaxis, especially anticoagulants at therapeutic doses, was selectively implemented in COVID-19 patients with comorbidities and severe COVID-19 status at admission.

Abstract
Background
Balloon pulmonary angioplasty (BPA) would be promising treatment option for non-operable chronic thromboembolic pulmonary hypertension (CTEPH). However, BPA for CTEPH with Chronic obstructive pulmonary disease (COPD) might exacerbate ventilation perfusion mismatch. The aim is to evaluate the efficacy and safety of BPA for CTEPH with moderate or severe COPD.
Method
Data from 149 CTEPH patients were collected retrospectively who underwent BPA from March 2011 to June 2021. Patients were divided according to the comorbidity of COPD: a COPD group (defined as forced expiratory volume in one second (FEV1.0) / forced vital capacity (FVC)<70% and FEV1.0<80% predicted [n=32]) or a non-COPD group [n=101]. Mild COPD patients (n=16) were excluded. Hemodynamics and respiratory parameters were compared.
Results
Hemodynamics improved similarly in both group (percent decrease of pulmonary vascular resistance; −61.1±12.3% in a COPD group, −65.8±11.1% in a non-COPD group, p=N.S). Patients in a COPD group showed improved respiratory function and oxygenation with FEV1.0% from 61.8±7.0% to 66.5±10.2% (p=0.02), and partial pressure of arterial oxygen from 60.9±10.6mmHg to 69.3±13.6mmHg (p<0.01). Higher vital capacity (r2=0.123, p=0.024), higher diffusing capacity for lung carbon monoxide (r2=0.308, p=0.028) at baseline were correlated with larger improvement of oxygenation after BPA in multivariate linear analyses. Lung injury per session was 1.6% in a COPD group.
Conclusion
The efficacy and safety of BPA for non-operable CTEPH with COPD were equivalent to those of patients without COPD. Oxygenation and FEV1.0% also improved in COPD patients. BPA might be considered even though patients comorbid COPD.

Abstract
BACKGROUND Long-standing atrial fibrillation is associated with atrial functional mitral regurgitation (AFMR) with atriogenic tethering. We compared the outcomes of patch augmentation (PA) and valve replacement (VR) for AFMR. METHODS We retrospectively compared the data of 16 patients who underwent PA for AFMR with the data of 15 patients who underwent VR between 2008 and 2021. Patients with a left ventricular ejection fraction (LVEF) of <50% were excluded. We also performed atrial plication and left appendage closure if the patients had no weak atrial wall that led to severe bleeding. RESULTS The median age was 72.5 and 76.0 years in the PA and VR groups, respectively. The PA group had a longer cardiopulmonary bypass time (206 vs. 172 min, P=0.012). Although there were no differences in hospital morbidity and mortality between the PA and VR groups, one patient underwent reoperation for patch perforation in the PA group. The overall 3-year survival rate was 93.8% and 100% in the PA and VR groups, respectively (P=0.878). The 3-year rate of freedom from major adverse cardiac events was 75.0% and 53.6% in the PA and VR groups, respectively (P=0.181). Three and six patients were readmitted for congestive heart failure in the PA and VR groups, respectively. Two patients in the PA group developed severe recurrent regurgitation, including one patient who required reoperation. No patients in the VR group required reoperation. The postoperative left atrial volume index (LAVI) was associated with thromboembolic events (P=0.016). CONCLUSIONS PA may achieve comparable outcomes to those of VR for AFMR. Operative procedures should be chosen based on each patient's background. Atrial reduction could be considered to prevent thromboembolic events.

Abstract
BACKGROUND AND PURPOSE CNS lesions of tuberous sclerosis complex are diagnosed mainly by T2WI, FLAIR, and sometimes T1WI with magnetization transfer contrast. The usefulness of T1WI with chemical shift selective images was recently reported in focal cortical dysplasia type IIb, which has histopathologic and imaging features similar to those of tuberous sclerosis complex. We investigated the usefulness of the T1WI with chemical shift selective images in detecting CNS lesions of tuberous sclerosis complex. MATERIALS AND METHODS We retrospectively reviewed 25 consecutive patients with tuberous sclerosis complex (mean age, 11.9 [SD, 8.9] years; 14 males) who underwent MR imaging including T1WI, T1WI with magnetization transfer contrast, T1WI with chemical shift selective, T2WI, and FLAIR images. Two neuroradiologists assessed the number of CNS lesions in each sequence and compared them in 2 steps: among T1WI, T1WI with magnetization transfer contrast and T1WI with chemical shift selective images, and among T2WI, FLAIR, and T1WI with chemical shift selective images. We calculated the contrast ratio of the cortical tubers and of adjacent normal-appearing gray matter and the contrast ratio of radial migration lines and adjacent normal-appearing white matter in each sequence and compared them. RESULTS T1WI with chemical shift selective images was significantly superior to T1WI with magnetization transfer contrast for the detection of radial migration lines and contrast ratio of radial migration lines. There was no significant difference between T1WI with chemical shift selective images and T1WI with magnetization transfer contrast for the detection of cortical tubers and the contrast ratio of the cortical tubers. Both T2WI and FLAIR were statistically superior to T1WI with chemical shift selective images for the detection of cortical tubers. T1WI with chemical shift selective images was significantly superior to T2WI and FLAIR for the detection of radial migration lines. CONCLUSIONS The usefulness of T1WI with chemical shift selective images in detecting radial migration lines was demonstrated. Our findings suggest that the combination of T1WI with chemical shift selective images, T2WI, and FLAIR would be useful to evaluate the CNS lesions of patients with tuberous sclerosis complex in daily clinical practice.

Abstract
We created a novel ring-type knot pusher with a closed triangle tip, wherein the thread is never detached from the knot pusher head during the ligation process. This knot pusher has a small head and is suitable for complex fields, such as the subvalvular apparatus of the mitral valve, allowing the surgeons to observe the knot itself. Considering that the thread passes through the inner corner of the triangle during the tying-down process without swinging inside the triangle, this knot pusher allows for a stable and secure ligation.

Abstract
OBJECTIVES
The morphology of the tricuspid valve (TV), particularly valves with two posterior leaflets, is attracting attention. The present study was performed to investigate the usefulness of three-dimensional transoesophageal echocardiographic data for morphological evaluation of the TV .
METHODS
Sixty patients underwent morphological evaluation of the TV by preoperative transoesophageal echocardiography followed by TV repair with median sternotomy, and each leaflet was measured intraoperatively. We analysed the TV morphology in 51 patients whose preoperative echocardiographic findings were consistent with intraoperative findings.
RESULTS
The mid-systolic echo data, which included the annulus diameter of each leaflet, were correlated with the intraoperative evaluation findings compared with those in the mid-diastole. The annulus and area of the posterior leaflet were larger in patients with two than one posterior leaflet valve (42.4 ± 13.5 vs 30.7 ± 9.1 mm, P < 0.001 and 327 ± 185 vs 208 ± 77 mm2, P = 0.006, respectively). In the severe tricuspid regurgitation patients, the annulus of the posterior leaflet was larger and the annulus of the anterior leaflet was smaller in patients with two than one posterior leaflet valve [posterior: 48 mm [95% confidence interval (CI), 41–54 mm] vs 36 mm (95% CI, 27–45 mm), respectively; P = 0.043 and anterior: 38 mm (95% CI, 33–42 mm) vs 46 mm (95% CI, 40–52 mm), respectively; P = 0.025].
CONCLUSIONS
Patients who had a TV with two posterior leaflets had a larger annulus and area of the posterior leaflets. Preoperative three-dimensional transoesophageal echocardiography is useful for the morphological evaluation of the TV.

Abstract
BackgroundElevated serum IgG4 levels are one of the characteristic findings in immunoglobulin G4 (IgG4)-related disease (IgG4-RD). Serum IgG4 levels have an impact to a certain extent on the diagnosis of IgG4-RD although there are some issues in their sensitivity and specificity. In the reports from Japan, China, USA, and Europe, elevated serum IgG4 levels were reported to be observed in 83-97% of patients with IgG4-RD [1-5]. In the past investigations of hospital patients, some studies reported that 10-15% of hospital patients with elevated serum IgG4 levels had IgG4-RD [6,7]. However, in general adults with no symptom, investigations of prevalence of elevated serum IgG4 levels and/or IgG4-RD have rarely been conducted.ObjectivesThis study aimed to investigate the frequency of serum IgG4 elevation in the general Japanese population and its associated factors using data from resident examinations.MethodsWe measured the serum IgG4 levels in 1,204 residents who underwent a general medical examination in Ishikawa prefecture, Japan. Logistic regression analysis was used to search for factors related to elevated serum IgG4 levels. Secondary examinations were conducted for participants in whom elevation was identified.ResultsThe mean serum IgG4 level was 44 mg/dL, and elevated serum IgG4 levels were observed in 42 patients (3.5%). Univariate logistic regression analyses showed that male sex, older age, lower estimated glomerular filtration rates based on cystatin C (eGFR-CysC), serum high-density lipoprotein cholesterol levels, and higher hemoglobin A1c (HbA1c) levels were associated with elevated serum IgG4 levels. Subgroup analyses in men showed that older age, lower eGFR-CysC levels, and higher serum HbA1c levels were associated with elevated serum IgG4 levels. In contrast, the analyses in women found no significant factors. One of the 10 residents who underwent secondary examinations was diagnosed with possible IgG4-related retroperitoneal fibrosis.ConclusionIn the general population, elevated serum IgG4 levels are more common in elderly men, which is similar to the epidemiological features of IgG4-RD.References[1]Inoue D, et al.

Abstract
BackgroundRapidly progressive interstitial lung disease (RP-ILD) associated with anti-melanoma differentiation-associated protein 5 (MDA5) autoantibody (Ab) -positive dermatomyositis (DM) is one of the most life-threatening autoimmune conditions. The clinical course is very rapid, leading to death within three months after the onset of symptoms. Although triple therapy which consists of corticosteroids, cyclophosphamide, and tacrolimus has been considered as standard therapy and additional treatments including plasma exchange (PE) and rituximab (RTX) have been reported, the survival rate of patients with poor prognostic factors is still poor even if all of these treatments were applied. Recently, there exist increasing evidences regarding the efficacy of tofacitinib (TOF) in refractory DM. We have treated anti-MDA5Ab-positive RP-ILD with multiple poor prognostic factors with high-intensity induction therapy which combined triple therapy, PE, RTX, and TOF.ObjectivesThis study aimed to investigate the therapeutic efficacy of high-intensity induction therapy for patients with anti-MDA5Ab-positive RP-ILD with multiple poor prognostic factors.Methods31 patients who were diagnosed with anti-MDA5Ab-positive DM during 2014 to 2021 in our institution were included in this study. The clinical characteristics for poor prognosis were retrospectively analyzed, and the outcomes of high-intensity induction therapy were analyzed for the survival and adverse events.Results17 cases were treated before the introduction of TOF. Although triple therapy with RTX, PE, or intravenous immunoglobulin (IVIG) were used, eight out of 10 RP-ILD cases with a ferritin level >400 ng/mL (range, 402.5-5,831; mean, 2,342 ± 2,069) died in median 2.5 months. Poor prognosis was predicted by followings; elevated levels of serum ferritin, lactate dehydrogenase, transaminases, creatinine phosphokinase, and C-reactive protein; decrease in platelets, serum albumin, and oxygen saturation; use of oxygen; higher age; shorter disease duration to admission. The addition of RTX and PE was not enough to control RP-ILD in anti-MDA5Ab positive DM, and prevention of the initial exacerbation of ILD following induction therapy was considered to be important. Based on these observations, high-intensity induction therapy was consisted as follows; triple therapy with decreasing the dose of methylprednisolone by half from 1g to 1 mg/kg, liposteroid to suppress macrophage activity, TOF, PE, and RTX. High-intensity induction therapy was applied in eight patients (ferritin levels; range, 412.2-7,095 ng/mL; mean, 3,558±3,152 ng/mL) with multiple poor prognostic factors described above. Although deaths at two months and eight months due to ILD were observed, significant improvement of survival was documented (Figure 1). Two patients in whom RTX was not initially administered, exacerbation of ILD was observed one month later, which prompted the use of RTX. Several adverse events were observed in high-intensity induction therapy. The most common events were reactivation of cytomegalovirus, meanwhile herpes zoster was not documented. Sustained leukocytopenia and thrombocytopenia were observed in three patients, and two patients developed thrombotic microangiopathy which led to the discontinuation of tacrolimus. Fungal infections in lung were also documented. These adverse events were controllable.Figure 1.ConclusionSignificant improvement of survival was observed in patients treated with high-intensity induction therapy. Meanwhile, stratification of patients for poor prognosis would be important.ReferencesNoneDisclosure of InterestsNone declared

Abstract
OBJECTIVE We assessed the long-term outcomes of the loop technique with ring annuloplasty for mitral regurgitation from our > 10-year experience. METHODS We retrospectively reviewed 362 patients who underwent the loop technique with ring annuloplasty via median sternotomy or right mini-thoracotomy for mitral regurgitation. The median follow-up duration was 4.1 years (interquartile range 2.3-5.8 years). RESULTS This study involved 147 women and 215 men (median age, 66.5 years). Mitral regurgitation was caused by Barlow's disease in 27 patients. Seven patients required reoperations (recurrent regurgitation caused by technical issues, n = 3; progression of degenerative disease, n = 4). The 5- and 10-year cumulative incidences of reoperation considering death as the competing event were 1.4% and 5.4%, respectively. The 5- and 10-year postoperative cumulative incidences of moderate-to-severe recurrent mitral regurgitation were 4.7% and 13.0%, respectively. Residual regurgitation ≥ mild (hazard ratio, 6.99; 95% confidence interval, 1.520-32.12; P = .012) was an independent risk factor for reoperation. The independent risk factors for moderate-to-severe recurrent regurgitation were residual regurgitation ≥ mild (hazard ratio, 9.60; 95% confidence interval, 3.042-30.31; P < .001) and the loop-in-loop technique (hazard ratio, 3.40; 95% confidence interval, 1.058-10.90; P = .040). The median mean pressure gradient was sustained at almost 3.5 mmHg for > 7 years. CONCLUSIONS The loop technique with ring annuloplasty provided excellent results with good hemodynamics beyond the mid-term. Residual regurgitation ≥ mild and the loop-in-loop technique may not be preferable for durable outcomes.

Abstract
Objective We investigated the effect of morphological diversity of the tricuspid valve with multiple posterior leaflets on the technical outcomes of tricuspid valve repair. Methods From April 2016 to November 2020, 141 patients were diagnosed with secondary tricuspid regurgitation associated with left heart disease and underwent tricuspid valve repair. We retrospectively analyzed the clinical and echocardiographic data of patients who underwent both preoperative and postoperative transthoracic echocardiography. We divided the patients into two groups according to the surgical technique used to treat tricuspid regurgitation: ring annuloplasty alone (Group 1, n = 109) or additional approximation of leaflet edges (edge-to-edge repair) with ring annuloplasty (Group 2, n = 32). We measured the morphological diversity of the tricuspid valve during the operation in all patients. Results The preoperative tricuspid regurgitation score was higher in Group 2 than in Group 1 (2.1 ± 0.78 vs. 1.6 ± 0.7, respectively; p = 0.0046), and Group 2 contained more patients with two posterior leaflets than Group 1 [20 (63%) vs. 36 (33%), respectively; p = 0.003]. The univariate and multivariate logistic regression analyses showed that the presence of two posterior leaflets was an independent risk factor for additional procedures during tricuspid valve repair (odds ratio, 2.6; 95% confidence interval, 1.1–6.1; p = 0.033). Conclusions Additional procedures to reduce tricuspid regurgitation were required more frequently in patients with two posterior leaflets of the tricuspid valve. The morphological diversity of two posterior leaflets is a potential risk factor for a more complicated tricuspid repair.

At onset of acute heart failure (AHF), various clinical fundamental parameters including vital sign, laboratory data, or initial treatment were investigated, and we can roughly estimate the prognosis. However, machine learning method for prediction of the prognosis was not studied.
Purpose
To elucidate prognostic value of machine learning for AHF comparing conventional statistical model.
Methods
We enrolled consecutive 300 patients with AHF (79.5 ± 12.1 years, 158 Males). Patients with acute coronary syndrome, mechanical circulatory support cases, and cardio-pulmonary arrest cases were excluded. The patients were randomly divided into 80% (240 cases) and 20% (60 cases), and the former was used as train data, and the latter as validation data. Objective variable was set as cardiac death in one year. First, logistic regression analysis with Akaike’s information criterion (AIC) was performed, and extracted predictive parameters. The predictive model for the cardiac prognosis was constructed by cut-off value of ROC curve analysis of propensity score was calculated. Next, machine learning (random forest method and deep learning) to build predictive model was performed with the predictors. Finally, accuracy of each predictive model was compared.
Results
Thirty cases showed cardiac death in one year. Logistic regression with AIC extracted 8 predictors, and the cut off-value of propensity score with the 6 parameters was 0.110. The accuracy was 0.714 and area under ROC (AUROC) was 0.836. Conversely, random forest method demonstrated the accuracy as 0.927, AUROC 0.860. On deep learning, the accuracy was 0.937 and AUROC 0.901.
The top 4 high feature importance of random forest were Cl/red blood cell count/pH/Anion Gap. However, accuracy of those predictors was lower than that of machine learning.
Conclusion
Machine learning was a powerful tool to predict cardiac prognosis of AHF, comparing with conventional statistical model. Abstract Figure. Statistical model

Abstract
OBJECTIVES Cases in which the left circumflex coronary artery (LCX) runs close to the mitral annulus are considered high risk for LCX injury during mitral surgery. We investigated the anatomical relationship between the LCX and the mitral annulus using 3-dimensional (3D) computed tomography (CT). METHODS We constructed 3D-CT images of the LCX and the mitral annulus before surgery in 122 patients with mitral regurgitation (MR). We classified coronary dominance by 3D-CT and MR aetiologies (degenerative, atrial functional MR, ventricular functional MR and Barlow's disease) using echocardiography. We detected the point on the mitral annulus closest to the LCX (X point) and measured the minimum distance from the LCX to the mitral annulus (mCAD). We judged whether atrioventricular disjunction existed using CT. We also investigated the factors affecting mCAD and examined how coronary dominance and MR aetiologies relate to the location of the X point. RESULTS The median mCAD was 4.2 mm (range 0.9-11.4 mm). Considering coronary dominance and MR aetiologies, mCAD was shorter in patients with left coronary dominance and Barlow's disease. The X point mostly existed on the lateral side of the posterior annulus, but it sometimes existed on the medial side. Multiple regression revealed left dominance and mitral annular disjunction as significant factors affecting mCAD (P = 0.01). CONCLUSIONS The anatomical relationship between the LCX and the mitral annulus can be recognized using superimposed 3D-CT images. This approach is useful to avoid LCX injury in mitral valve surgery since the X point varies between patients.

Abstract
Abstract
Background
Several patients with persistent atrial fibrillation (per-AF) suffer from recurrence after pulmonary vein isolation (PVI). Various methods to predict the recurrence were tried, but deep learning on 12-leads electrocardiography (ECG) after PVI was not studied.
Purpose
To elucidate diagnostic performance of deep learning on 12-leads ECG after PVI in patients with per-AF
Methods
We enrolled consecutive 109 patients with per-AF who underwent PVI (68.8±10.0 years, 83 males) excluding failure cases. We defined recurrence in 3–12 months after PVI. From the ECG just after PVI, five beats of each lead were sampled separately. Deep learning (convolutional neural network on bitmap ECG image) was performed by transfer learning of Inception-Resnet-V2 model. Gradient weighted class activation color mapping (GradCam) was performed to detect convolutional importance in the lead.
Results
Thirty-six patients showed recurrence in the period. Lead II (accuracy 0.701), aVR (0.690) were the top 2 leads of prediction, which showed larger accuracy than statistical accuracies of Non PV foci = SVC (accuracy = 0.541) and left atrial diameter >50mm (0.596). In lead II, GradCam spotlighted strong convolution of latter half of P wave in recurrent case, and former half of P wave and T wave in no-recurrent case.
Conclusions
Deep learning on ECG was a powerful tool to predict recurrence of per-AF after PVI.

Abstract
PURPOSE Our study aims to examine the midterm outcomes of the loop technique for extended mitral valve (MV) prolapse patients. METHODS From October 2008 to August 2020, we performed MV repairs in 407 patients with severe mitral regurgitation (MR). Follow-up ranged in duration from 287 to 2899 days (median, 872 days). The prolapse extensiveness (p-score) was determined based on the ratio of prolapsing segment's areas to whole area. We divided the whole MV into 10 segments (A1, A2 medial, A2 lateral, A3, P1, P2 medial, P2 lateral, P3, AC, and PC). Patients were categorized into three groups according to the p-score: simple (0.1-0.2), intermediate (0.3-0.4), and extensive (0.5-0.9). RESULTS All patients underwent MV repair with the loop technique. The rates of freedom from significant (moderate to severe or severe) MR at 5 and 7 years after surgery were 91% and 91%, respectively. There were 252, 115, and 40 patients in simple group, intermediate group, and extensive group, respectively. The following were significantly increased in extended group: Barlow disease (23/40 patients, p < .001), the number of loops (p for trend < .0001), and the technique score (p for trend < .0001). The rates of freedom from significant MR at 7 years after surgery were 92% in simple group, 87% in intermediate group, and 94% in extended group, respectively (p = .995). Receiver-operating characteristic curves showed a postoperative mild MR with a sensitivity of 86% and a specificity of 68% for predicting significant MR recurrence. CONCLUSIONS MV repair using the loop technique was useful even in groups with extended prolapse.

Abstract
In this study, we report the case of a 47-year-old female who presented with extensive acute type IIIb aortic dissection and cerebral infarction. At 69 years of age, dilatation of the descending aorta was noted to be more than 70 mm with compression of the left atrium. We performed endovascular repair with distal false lumen occlusion. However, further dilatation of the descending aorta with false lumen flow from the re-entry of the common carotid artery was detected. She subsequently underwent additional proximal false lumen occlusion by embolization at the aortic arch. A year later, as per her computed tomography angiography findings, appreciable shrinkage of the descending aorta without endoleakage was observed.

Abstract
Background:Methotrexate has been an anchor drug for patients with rheumatoid arthritis (RA). However, it is strictly prohibited to prescribe MTX to patients with severely decreased renal function because it can induce a fatal adverse event such as pancytopenia in these patients. On the other hand, since the average age of RA patients is gradually increasing, and many of them already have mildly to moderately impaired renal function, their renal function can easily decrease to below the critical level of the estimated glomerular filtration rate. Therefore, new development of acute kidney injury (AKI) during MTX administration might induce a fatal adverse event, making the identification of patients susceptible to AKI very important.Objectives:To clarify the frequency of AKI and the factors involved in it in RA patients.Methods:Two hundred and fifty-two RA patients (211 females, 41 males, mean age 62.3 ± 12.5 years, disease duration 11.0 ± 9.5 years) diagnosed more than 3 years earlier and followed for more than 5 years, and also, others diagnosed ≥3 years earlier but followed for ≤5 years were enrolled. We measured BUN, Cr, RF and aCCP in patient serum, urinary proteins, urinary blood, and urinary casts and evaluated CDAI, SDAI, disease activity score (DAS) 28-CRP and DAS28-ESR. Steinbrocker functional classification and radiological grading were evaluated. History of diabetes mellitus, hypertension and hyperlipidemia was determined from the medical records. Medications for RA, including non-steroid anti-inflammatory drugs (NSAIDs), prednisolone, csDMARD (MTX, Tacrolimus, etc.), bDMARDs and tsDMARDs were evaluated. Estimated glomerular filtration rate (eGFR) was calculated by the new Japanese coefficient-modified Modification of Diet in Renal disease (MDRD) study equation. The criteria of AKI were that serum Cr increased by 0.3 mg /dl or increased by 1.5-fold between consecutive visits according to the KIDIGO criteria 1) and the report of Leither et al2).Results:Twenty (7.9%) patients developed AKI, 22 times. The causes of AKI were 10 infections, 6 dehydrations, 2 enteritis, 1 urticaria, 2 hypercalcemia due to VitD administration, and 1 ureteral stone. We divided our patients into group A (with AKI) and group B (without AKI). Group A was older (69.9±10.1 vs 61.7±12.6 years), had greater physician VAS (29.5±27.7 vs 15.7±18.3 mm), higher serum creatinine (0.79±0.19 vs 0.60±0.16 mg/dl), higher BUN (18.4±5.7 vs 15.1±4.4 mg/dl), lower eGFR(65.5±23.3 vs 86.4±22.4 ml/min), more frequent prednisolone administration (75.0% vs 41.9%), more frequent hyperlipidemia (50.0% vs 19.2%) and more frequent hypertension (60.0% vs 30.6%) than Group B by univariate analysis significantly (p<0.01). We then performed multifactorial analysis using logistic regression analysis. Greater physician VAS (OR 1.02, 1.00-1.04), lower eGFR (OR 1.04, 1.01-1.08) and prednisolone administration (OR 3.29, 1.02-10.63) were found as independent relevant factors for group A.Conclusion:Our study indicated that AKI developed in RA patients and suggested that renal function decline and prednisolone administration may be implicated. RA patients with impaired renal function and prednisolone administration need to be treated with special attention to the onset of AKI.References:[1]Kidney Disease: Improving Global Outcomes (KDIGO) Practice Guideline for Acute Kidney Injury.

Abstract
Objective: Although biologic agents are used in Takayasu arteritis (TAK), corticosteroids are still the mainstay of treatment. This study aimed to investigate the feasible maintenance dose of prednisolone (PSL) in the biologic therapy era.Method: We enrolled 93 patients with TAK who satisfied the criteria of the American College of Rheumatology and visited our department from 2008 to 2018. The clinical characteristics and PSL dose of the patients were retrospectively evaluated.Results: The mean ± sd maintenance dose of PSL was 5.0 ± 3.0 mg/day. In patients having TAK for > 20 years, PSL discontinuation and drug-free status were achieved in 27.2% and 18%, respectively. Although tapering the PSL dose to 10 mg/day was achieved within 12 months, tapering to 5 mg/day required 10 years. Relapse significantly interfered with the PSL dose reduction. The clinical characteristics of patients with relapse included a lower rate of combination therapy using immunosuppressants. Moreover, biologics were used in > 60% of patients with relapse. Tapering of PSL was significantly possible in patients receiving biologics and additional relapse was observed in 6.3% and 50% of patients with and without biologics, respectively. Such PSL-sparing effect enabled the reduction of the median PSL dose from 10 to 5 mg/day. Steroid discontinuation was achieved in some patients.Conclusions: The use of biologics significantly reduced the PSL dose in relapsed patients. A PSL dose of ≤ 5 mg/day is a feasible target for TAK, especially when biologic agents are used. Nevertheless, corticosteroid discontinuation may also be the target in some patients.

Abstract
Background Vascular invasion involving a tumor thrombus in the inferior vena cava and/or right atrium is an unfavorable prognostic factor after intrahepatic cholangiocarcinoma resection. We report an intrahepatic cholangiocarcinoma case with a tumor thrombus extending from the left hepatic vein via the inferior vena cava to the right atrium. Case presentation A 58-year-old man with epigastralgia was referred to our hospital after an emergent transcatheter arterial embolization was done following the radiological diagnosis of a ruptured hepatic tumor. The serum concentrations of carcinoembryonic antigen, carbohydrate 19-9, duke pancreatic monoclonal antigen type 2, and cytokeratin-19 fragments were elevated; meanwhile those of alfa-fetoprotein and des-γ-carboxy prothrombin were within normal ranges. A contrast-enhanced computed tomography scan showed a heterogeneously enhanced tumor, 13 cm in diameter, in the left lobe of the liver, enlarged lymph nodes along the lesser curvature of the stomach, and a tumor thrombus extending from the left hepatic vein via the inferior vena cava to the right atrium. We performed a left hemihepatectomy and tumor thrombectomy under total hepatic vascular exclusion to reduce the risk of sudden death. After dissection of the liver parenchyma along the left side of the middle hepatic vein, except for the left hepatic vein, the inferior vena cava just below the right atrium could be clamped by pulling down the left lobe of the liver toward the caudal side. The thrombus could be removed by incising the inferior vena cava under total hepatic vascular exclusion. Microscopic examination showed a tubular adenocarcinoma. Immunohistochemical staining was positive for cytokeratin-7, cytokeratin-19, and epithelial membrane antigen, but negative for arginase-1, glypican-3, and hepatocyte. The patient was pathologically diagnosed with an intrahepatic cholangiocarcinoma with a tumor thrombus in the inferior vena cava. Adjuvant chemotherapy with tegafur/gimeracil/oteracil was administered for 1 year. The patient remained in good health without cancer recurrence for over 4 years after the operation. Conclusion An aggressive surgical approach may be indicated for intrahepatic cholangiocarcinoma with a tumor thrombus in the inferior vena cava and/or right atrium to avoid the risk of impending death.

Abstract
Background The frozen elephant trunk technique is useful in aortic arch repair; however, some adverse events are associated with the Frozenix J-graft. We designed a technique to prevent these adverse events and achieve easy anastomosis (Total Exclusion of the Non-Stent part of Frozenix using an Everting anastomosis [TENSE]), and we assessed the outcomes of this technique in the present study. Methods From April 2017 to May 2021, 44 patients with aortic arch disease underwent TENSE, in which the proximal stump of the stent part of Frozenix was matched to the distal anastomosis end between the left common carotid and left subclavian arteries. Results The median age of the patients (35 men, 9 women) was 76.5 years. The predicted mortality and morbidity rates were 10.0% and 40.2%, respectively, according to the JapanSCORE II. Two patients (4.5%) died of aneurysm rupture and interstitial pneumonia, respectively, during hospitalization. Four patients (9.1%) who developed postoperative cerebral infarction had a previous cerebral infarction (P=0.010). No patients developed spinal cord complications or Frozenix kinking. Follow-up computed tomography showed no endoleaks or aneurysmal dilatation, although one patient had possible distal stent graft-induced new entry. Conclusions Our strategy provided good early outcomes without spinal cord complications or Frozenix kinking in patients with aortic arch disease. Continuous follow-up is needed to avoid missing distal changes.

Abstract
The World Health Organization declared COVID-19 a global pandemic on the 11th of March 2020, but the world is still reeling from its aftermath. Originating from China, cases quickly spread across the globe, prompting the implementation of stringent measures by world governments in efforts to isolate cases and limit the transmission rate of the virus. These measures have however shattered the core sustaining pillars of the modern world economies as global trade and cooperation succumbed to nationalist focus and competition for scarce supplies. Against this backdrop, this paper presents a critical review of the catalogue of negative and positive impacts of the pandemic and proffers perspectives on how it can be leveraged to steer towards a better, more resilient low-carbon economy. The paper diagnosed the danger of relying on pandemic-driven benefits to achieving sustainable development goals and emphasizes a need for a decisive, fundamental structural change to the dynamics of how we live. It argues for a rethink of the present global economic growth model, shaped by a linear economy system and sustained by profiteering and energy-gulping manufacturing processes, in favour of a more sustainable model recalibrated on circular economy (CE) framework. Building on evidence in support of CE as a vehicle for balancing the complex equation of accomplishing profit with minimal environmental harms, the paper outlines concrete sector-specific recommendations on CE-related solutions as a catalyst for the global economic growth and development in a resilient post-COVID-19 world.

Abstract
A 70-year-old man, diagnosed with severe mitral regurgitation and moderate tricuspid regurgitation with situs inversus totalis, was referred to our hospital. A minimally invasive approach via a minithoracotomy was performed. The mitral valve was repaired with the loop technique and ring annuloplasty. With an asymmetric shape of the tricuspid valve, the use of a conventional rigid ring was not feasible. Therefore, flexible ring annuloplasty had to be performed. The minimally invasive approach for mirror-image anatomy did not pose an unusual technical challenge. It was safely performed in the context of situs inversus totalis.

Abstract
Abstract
Background
Dual-isotope (low doze 201TlCl and 123I-β-methyl-P-iodophenyl-pentadecanoic acid (BMIPP)) single photon emission computed tomography (SPECT) is utilized to estimate myocardial damage in patients with congestive heart failure (CHF). However, predictive model construction on the SPECT for cardiac death by machine learning was not studied.
Purpose
To elucidate predictive value of machine learning model on dual-isotope SPECT for CHF.
Methods
We enrolled consecutive 310 patients who admitted with CHF (77.1±3.1 years, 164 males). After initial treatment, they underwent electrocardiography gated SPECT and observed in median 507 days [IQR: 165, 1032]. Multivariate Cox regression analysis for cardiac death was performed, and predictive model was constructed by ROC curve analysis and machine learning (Random Forest and Deep Learning). The accuracies (= [True positive + True negative] / Total) of the prediction models were compared with ROC curve model.
Results
Thirty-six patients fell into cardiac death. Cox analysis showed Age, left ventricular ejection fraction (LVEF), summed rest score (SRS) of BMIPP, and mismatch score were significant predictors (Hazard ratio: 1.068, 0.970, 1.032, 1.092, P value: <0.001, 0.014, 0.002, <0.001, respectively). ROC curve analysis of them revealed the accuracy of the cut-off value was 0.479–0.773. Conversely, machine learning model demonstrated higher accuracy for cardiac death (Random Forest: 0.895, Deep Learning: 0.935). The top 4 feature importance of the random forest were LVEF (0.299), SRS BMIPP (0.263), Age (0.262), and mismatch score (0.160).
Conclusion
Machine learning model on SPECT was superior to conventional statistic model for predicting cardiac death in patients with CHF.

Abstract
Abstract
Background
Bioabsorbable polymer drug eluting stents (BP-DESs) were designed to reduce a vascular inflammatory reaction compared to durable polymer drug eluting stents (DP-DESs). However, few studies have compared vascular responses to BP-DESs and DP-DESs.
Methods
We enrolled 88 consecutive patients with single culprit coronary artery lesions (31 lesions with acute coronary syndrome) undergoing a single stent-implantation. BP-DESs and DP-DESs were implanted in 50 (57%) and 38 patients (43%), respectively. All lesions underwent optical coherence tomography examination at chronic phase and intrastent OCT findings at the follow-up were evaluated in every 1-mm cross-sections (CSs).
Results
A total of 1887 CSs (BP-DES: 1096, DP-DES: 791) were analyzed. The median period of follow-up OCT was 293 (250–374) days. There were no differences in the patient, lesion, and initial clinical presentation of acute coronary syndrome (ACS). BP-DESs had significantly higher percent neointimal hyperplasia area, defined as neointimal hyperplasia area divided by stent area x 100 (18.4±9.0% vs. 16.1±9.9%, p<0.001), fewer malapposed struts (1.7% vs. 3.9%, p=0.005), fewer uncovered struts (3.6% vs. 5.8%, p=0.02) but higher frequency of superficial low intensity neointima (LIN) (7.7% vs. 3.4%, p<0.001). Multivariate logistic analysis showed that BP-DES (OR: 2.5, 95% CI: 1.49–4.08, p<0.001) and the initial clinical presentation of ACS (OR: 2.31, 95% CI: 1.47–3.62, p<0.001) are independent predictive factors for LIN.
Conclusion
BP-DESs showed homogenous neointimal growth and complete stent coverage quantitatively. Meanwhile, the significant relationships of BP-DES with LIN may suggest that the neointimal quality remains immature in BP-DESs in this period.

Abstract
Abstract
Background
Histopathological analysis or intracoronary image assessment of healed plaques (HPs) has been reported both in acute coronary syndrome (ACS) and stable angina pectoris (SAP) patients. However, background characteristics or lesion morphologies of HPs could not be fully clarified and their differences according to the clinical status remain undetermined.
Purpose
We sought to investigate the clinical and morphological characteristics and compare their differences among ACS and SAP patients in order to clarify the clinical significance in HPs lesions.
Methods
We enrolled consecutive 201 patients with 213 native coronary artery lesions (139 lesions with SAP, 42 ST elevation-ACS (STE-ACS) and 32 non-ST elevation ACS (NSTE-ACS) undergoing pre-intervention optical coherence tomography (OCT). HPs was defined as layered phenotype on OCT. Clinical and angiography characteristics and lesion morphologies on OCT were assessed.
Results
HPs were observed in 110 lesions (51.6%) and their prevalence were not different according to the clinical status (SAP:55.1%, STE-ACS:38.1%, NSTE-ACS:56.3%, p=0.14). Lesions with HPs had higher frequencies of angiography-eccentric lesions (62.7% vs. 35.9%, p<0.001) and OCT-macrophages (65.5% vs. 43.1%, p<0.001), and greater OCT-lumen area stenosis (%-AS) (77.1±10.2% vs. 73.6±10.6%, p=0.01) than those without HPs. Of lesions with HPs, OCT-thin-cap fibroatheroma (SAP 14.4%, STE-AC43.8%, NSTE-ACS 16.7%, p=0.03), plaque rupture (5.3%; 37.5%; 11.1%, p<0.001) and thrombus (6.6%, 75.0%, 22.2%, p=0.007) were more frequently observed in STE-ACS than in SAP patients, whereas OCT-microvessels were more frequent in SAP than in ACS patients (19.7%, 0.0%, 0.0%, p=0.02). Other OCT findings such as macrophages, cholesterol crystal, multiple layered phenotype, and %-AS were not significantly different according to the clinical status. Multivariate logistic regression analysis identified the angiography-eccentric lesions (odds ratio (OR): 2.97, 95% confidence intervals (CI): 1.68–5.25, p<0.001) and OCT macrophages (OR 2.41, 95% CI 1.36–4.27, p=0.003) as independent related factors for the existence of HPs.
Conclusions
The present study showed that HPs lesions had eccentric and large plaque burden, and persistent plaque inflammations regardless of clinical status, which might lead to future coronary events.

Abstract
Abstract
Background
Many vulnerable plaques would progress without clinical events and might result in healed plaques (HPs). Histopathological or intracoronary image assessment of HPs has been reported. However, the morphological characteristics of HPs remain unclear yet.
Purpose
We sought to assess the healed vulnerable plaque components in patients with coronary artery lesions using optical coherence tomography (OCT) and coronary angioscopy (CAS).
Methods
We enrolled 47 patients with 50 native coronary artery lesions with angiographical severe stenosis (>90% diameter-stenosis) and without severe calcification (36 lesions with stable angina pectoris (SAP) and 14 acute coronary syndrome (ACS)) undergoing pre-intervention OCT and CAS. HPs was defined as layered phenotype on OCT. Lesion morphologies and plaque characteristics in lesions with HPs were assessed using OCT and CAS images.
Results
HPs were observed in 27 lesions (54.0%) and their prevalence were similar among each clinical status (SAP 52.8%, ACS 57.1%, p=1.00). Lesions with HPs had higher prevalence of OCT-macrophage (88.0% vs. 52.0%, p=0.01), CAS-red thrombus (88.8% vs. 52.2%, p=0.004) and CAS-low grade-yellow plaque (grade 1) (55.6% vs. 21.7%, p=0.02) than those without. SAP lesions with HPs had higher prevalence of CAS-yellow plaque (35.3% vs. 5.9%, p=0.09) and OCT-thin-cap fibroatheroma (42.1% vs. 5.9%, p=0.04) than SAP without HPs. ACS lesions with HPs had less CAS-red thrombus (0.0% vs. 50.0%, p=0.03) and OCT-plaque rupture (12.5% vs. 66.7%, p=0.04) than ACS without HPs. Multivariate logistic regression analysis revealed that OCT-macrophages (odds ratio (OR): 6.65, 95%-confidence intervals: 1.07–41.5, p=0.043), CAS-red thrombus (OR 8.77, 95% CI 1.33–57.8, p=0.02), and low grade-yellow plaque (OR 13.05, 95% CI 1.97–86.5, p=0.008) were independently related with the existence of HPs lesions. Combination of these 3 factors showed a high predictive value of OCT-HPs lesions (90.9%).
Conclusions
HPs lesions showed the lower lesion vulnerability than common ACS lesions but had more intraplaque inflammatory condition compared with common SAP lesions. Combined CAS and OCT examination might be useful to clarify the plaque components of HPs lesions in vivo, leading to help us understand the clinical significance of HPs.

Abstract
Background
Qualitative difference of ST elevation/depression on 12-leads electrocardiography (ECG) at onset was reported in patients with Takotsubo syndrome (TTS) and acute anterior myocardial infarction (ant AMI). However, quantitative difference of those was not elucidated.
Purpose
To investigate differences of ST level at J point on ECG between TTS and ant AMI by automated calculating system.
Methods
We firstly enrolled consecutive 40 patients of TTS, and among 500 ant AMI patients, one to two random matching was done by their age and gender. Finally, 40+80 patients (74.5±11.2 years, 87 females) were enrolled. ECG at onset of both group was measured by automated system (ECAPs12c: Nihon-Koden).
Results
ST level of TTS at J-point in I/II/V4–6 lead was significantly elevated comparing to that of ant AMI. Conversely, Conversely, significant ST depression in aVR and no ST elevation in V1 of TTS was observed in TTS. Logistic regression analysis revealed that ST elevation in I lead and no ST elevation in V1 lead showed high odds ratio and low P value.
Conclusion
Automated measured ST level at J-point was a powerful tool to distinguish TTS and ant AMI at onset.

Abstract
Abstract
Background
Electrocardiographic (ECG) features on acute phase of Takotsubo syndrome (TTS) is recognized to mimic that of acute anterior myocardial infarction (ant AMI). However, the difference of synthesized 18-leads ECG of both diseases was not elucidated.
Purpose
To elucidate diagnostic performance of 18-leads ECG to distinguish TTS and acute anterior AMI.
Methods
We firstly enrolled consecutive 40 patients of TTS, and among 500 ant AMI patients, one to two matching was done by their age and gender. Finally, 40+80 patients (74.5±11.2 years, 87 females) were enrolled, and ECG at onset of both group was estimated. Because of multicollinearity, all significant differences were compared by machine learning (Random Forest method).
Results
Prevalence of Q wave had no difference. Conversely, ST depression in TTS and ST elevation in ant AMI were significant differences in V7–9 leads. T-wave polarity of V3R-V9 leads were significantly different (flat T-wave in TTS and positive in ant AMI). Machine learning revealed T wave polarity in V7 lead had the highest feature importance.
Conclusion
18-leads ECG at onset had powerful diagnostic performance to distinguish the two diseases.

Abstract
An arteriovenous fistula is a rare complication of ruptured abdominal aortic or iliac artery aneurysms (IAAs). Its clinical symptoms depend on its size, with signs of heart failure dominating if the fistula is large. Herein, we present a case of arteriovenous fistula with an unusual presentation. An 86-year-old male patient presented with extreme lower extremity edema, skin erosion, and continuous lymphorrhea (starting 3 months prior). Despite the large fistula between the right common IAA and the left common iliac vein after the rupture of the aneurysm, he did not develop heart failure symptoms, as the large shunt was predominantly directed toward the left lower extremity due to iliac vein compression. Careful physical examination and a high index of suspicion could have contributed to an earlier diagnosis and management.

Abstract
A 62-year-old Japanese male presented with graft infection by Staphylococcus schleiferi 50 days after debranching of the left subclavian artery and frozen elephant trunk repair for the entry closure of a Stanford type B aortic dissection. The graft was removed, and the patient was successfully treated using in situ reconstruction of the arch with omental flap coverage, removal of the debranching graft, autologous iliac artery grafting, and longterm antibiotics. Domino reconstruction of the infected debranching graft using autologous external iliac artery and a Dacron graft can thus be a good option in similar cases.

Abstract
Background:Takayasu arteritis (TAK) is a chronic granulomatous vasculitis and affects large vessels in young female. It has been recognized that high numbers of patients with TAK possessed autoantibodies against vascular endothelium, which are called anti-endothelial cell antibodies (AECAs). Although their target antigens had not been identified for a long time, we utilized an expression cloning system for specific identification of cell-surface antigens and successufully identified endothelial protein C receptor (EPCR) and scavenger receptor class B type 1 (SR-BI) as major novel autoantigens in TAK. It was possible that identified novel autoantibodies were utilized for clinical application and elucidating pathomechanisms of TAK.Objectives:To reveal the clinical impact and pathogenic potential of novel autoantibodies in TAKMethods:Three hundred twenty-five patients with autoimmune diseases were enrolled: 80, TAK; 10, giant cell arteritis (GCA); and 235, other autoimmune diseases. The expressions of EPCR and SR-BI were examined in the aortic tissue from several diseases by immunohistochemistry. The presence of novel autoantibodies was measured in TAK and other autoimmune diseases. Clinical characteristics of patients with these autoantibodies were evaluated in TAK. To investigate the pathogenetic potential of these novel autoantibodies, vascular endothelial cells from umbilical vein, aortic artery, and pulmonary artery were examined for the endothelial cell activation. The effects of the novel autoantibodies upon the differentiation of immune cells were also evaluated.Results:In non-inflammatory aortic tissue, the expressions of EPCR and SR-BI were observed in the endothelium of vasa vasorum. Their expressions in the endothelium were augumented in TAK tissue. Novel autoantibodies against EPCR or SR-BI were detected in 34.6 % or 36.5 % of cases, respectively in TAK, and overlap was obsereved only in two cases, indicating their exclusive nature. These autoantibodies were specific for TAK among autoimmune rheumatic diseases, and they were not detected in patients with GCA with cranial involvement, suggesting different pathomechanisms among these diseases. The clinical characteristics of patients with anti-EPCR autoantibodies included high prevalence of stroke and ulcerative colitis. Surprisingly, anti-EPCR autoantibodies were also detected in patients with primary ulcerative colitis, suggesting their common pathomechanisms with TAK. Serial measurement of these novel autoantibodies revealed their correlation with disease activity of TAK. In machanistic studies, EPCR and SR-BI functioned as negative regulators of endothelial activation and chemokine production. EPCR further functioned in human T cells and ameliorated Th17 differentiation. Autoantibodies against EPCR and SR-BI blocked the functions of their targets, thereby promoting pro-inflammatory phenotype.Conclusion:EPCR and SR-BI are preferentially expressed in the endothelium of vaso vasorum and upregulated in TAK tissue. Autoantibodies against EPCR or SR-BI are specific for TAK among autoimmune rheumatic conditions and detected in about 70 % of TAK, suggesting their usefulness for the diagnosis, subclassification, and monitoring of TAK. Autoantibodies inhibit the resolution of activated immune responses and thus would lead to the chronic vascular inflammation.References:[1]Shirai T et al.

Abstract
Background:The renal involvement of primary Sjögren’s syndrome (pSS) is characterized by distal renal tubular acidosis (RTA), tubulointerstitial nephritis (TIN), and/or glomerulonephritis [1,2]. Kidney stones and nephrocalcinosis are presumably caused by subclinical distal tubular acidosis, but its clinical significance has not been clarified.Objectives:This study aimed to clarify the frequency and clinical features of patients with pSS with kidney stones and/or nephrocalcinosis.Methods:We examined 59 patients with anti SS-A/Ro positive pSS who underwent abdominal computed tomography and/or ultrasound between 1998 and 2019 at Kanazawa University Hospital. We identified 2 groups of patients with primary Sjögren’s syndrome: 1) patients with kidney stones and/or nephrocalcinosis (group A: n=19) and 2) those without kidney stones and/or nephrocalcinosis (group B: n=40), and retrospectively analyzed their clinical features.Results:Kidney stones and/or nephrocalcinosis were confirmed in 19 of 59 (32%) patients with pSS. The patients comprised 4 males and 55 females with an average age of 60 years (range, 30 to 83 years) and mean observation period of 96 months (range 1 to 336 months). Estimated glomerular filtration rate (eGFR) at the time of diagnostic imaging (group A vs group B: 71.5 ml/min/1.73 m2vs 82.8 ml/min/1.73 m2; p=0.37) and eGFR at last follow up (group A vs group B: 59.3 ml/min/1.73 m2vs 74.7 ml/min/1.73 m2;p=0.03) of group A were lower than those of group B and urinary β2-microgloblin (group A vs group B: 7222 μg/mL vs 437 μg/mL; p=0.01) and urinary N-acetyl-β-D-glucosaminidase (group A vs group B: 5.8 U/L vs 3.9 U/L; p=0.22) of group A were higher than those of group B, while serum electrolytes (sodium, potassium, chloride, calcium, phosphorus), fractional excretion of calcium (group A vs group B: 1.2% vs1.5%; p=0.916), ESSDAI (group A vs group B: 7.6 vs 4.3; p=0.069), and eGFR decrease rate were not significantly different.Conclusion:32% patients with anti SS-A/Ro positive pSS had kidney stones and/or nephrocalcinosis in our cohort and their presence might accelerate chronic renal dysfunction due to tubulointerstitial disease (subclinical RTA or TIN).References:[1]Jain A et al.

Abstract
Background:Recently, the 2019 ACR/EULAR classification criteria for IgG4-related disease (IgG4-RD) were published mainly to identify more homogeneous subjects for inclusion in clinical trials and observational studies [1]. However, although their high specificity is presumed to be useful to differentiate IgG4-RD from various mimickers, their value in daily clinical practice needs to be evaluated.Objectives:This study aimed to clarify the usefulness of the 2019 ACR/EULAR classification criteria for IgG4-RD and characteristics of false-negative patients in daily clinical practice.Methods:We retrospectively reviewed the medical records of 162 patients with IgG4-RD and 130 consecutive non-IgG4-RD patients (mimickers) diagnosed by experts whose serum IgG4 levels were measured at a single center in Japan. Using the collected data, we calculated sensitivity, specificity, and fulfillment rates for the entry criteria, exclusion criteria, and threshold of inclusion criteria points. In addition, to clarify the characteristics of false-negative cases in IgG4-RD, we performed an intergroup comparison of their clinical features including disease-specific autoantibodies.Results:Both the patients with IgG4-RD and mimickers were relatively old (66 and 65 years) with male predominance (67% and 60%). The final diagnoses of mimickers mainly consisted of cancer, lymphoma, vasculitis, sarcoidosis, multicentric Castleman’s disease, and atherosclerotic or infectious aortic aneurysm. The classification criteria had a sensitivity of 72.8% and a specificity of 100%. Of the 44 false-negative cases, one did not fulfill the entry criteria, 20 fulfilled one exclusion criterion, and 27 did not achieve sufficient inclusion criteria points. Compared with the true-positive cases, the false-negative cases had significantly fewer affected organs, lower serum IgG4 levels, higher serum CH50 levels, and lower prevalence of salivary/lacrimal gland and renal parenchymal lesions. They were also less likely to have had biopsies (61% vs 97%). Of note, positivity of disease-specific autoantibodies including SSA/Ro antibody, ANCA, ds-DNA antibody, and ACPA was the most common exclusion criterion fulfilled in 18 patients, only 2 of whom were diagnosed with a specific autoimmune disease (rheumatoid arthritis) complicated by IgG4-RD. The remaining 16 patients had no specific clinical symptoms related to such autoantibodies. In addition, compared with IgG4-RD patients without disease-specific autoantibodies, the 18 patients with them had almost equal serum IgG4 and complement levels, number of affected organs, and histopathology and immunostaining scores despite higher serum IgG and CRP levels.Conclusion:The present study suggests that the 2019 ACR/EULAR classification criteria for IgG4-RD has excellent diagnostic specificity and moderate sensitivity in daily clinical practice. Positive disease-specific autoantibodies alone, which lowered the sensitivity in this study, may have little clinical significance concerning the diagnosis of IgG4-RD.References:[1]Wallace ZS et al.

Abstract
Objective We assessed the long-term outcomes of the loop technique with the ink-dot marking test, an alternative to the ink test for aligning the mitral valve (MV) leaflet height, during MV repair. Methods We retrospectively reviewed 351 patients who underwent MV repair with the loop technique via median sternotomy or right mini-thoracotomy. The ink-dot marking test involves creation of a dotted line between the rough and clear zones in the anterior leaflet and the center of the posterior leaflet by gentian violet. According to this marking, we adjusted the fixing position of the loops with or without the loop-in-loop technique and additional neochordal repair. Results This study involved 141 women and 210 men (mean age, 63.7 ± 13.0 years). Forty-one patients required additional adjustment after the ink-dot marking test. No significant differences were found in the need for second arrest between patients who did and did not require additional adjustment after the ink-dot marking test (3 vs 32 patients, P = .782). Predischarge transthoracic echocardiography showed trivial residual MV regurgitation (MR) in 285 patients, mild in 64, and moderate in 2. Ten patients needed reoperations (9 MV replacements and 1 MV re-repair) because of recurrent MR during postoperative follow-up. The 3-, 5-, and 10-year postoperative cumulative incidence of moderate to severe recurrent MR was 3.6%, 6.0%, and 19.8%, respectively. Conclusions The loop technique with the ink-dot marking test provided good early and long-term results. This test may help to decrease residual MR, especially when using the loop technique.

Abstract
AIM The impact of glycaemic control on fracture risk is controversial, which may be due to the possible presence of hypoglycaemia. The aim of this study was to separately investigate the impacts of severe hypoglycaemia and poor glycaemic control on fracture risk in people with type 2 diabetes. METHODS Overall, 4706 Japanese participants (2755 men and 1951 postmenopausal women) with type 2 diabetes (mean age 66 years) were followed prospectively (a median of 5.3 years; follow-up rate, 97.6%), and were stratified by severe hypoglycaemia status and glycaemic control. The primary outcome was fractures at any anatomic site. RESULTS Fractures occurred in 662 participants (249 men and 413 women). The age- and sex-adjusted incidence rates (expressed per 1000 person-years) were: 71.2 (multiple episodes of severe hypoglycaemia), 43.1 (one episode), 25.2 [HbA1c < 53 mmol/mol (< 7%) without severe hypoglycaemia], 28.7 [HbA1c 53 to < 64 mmol/mol (7% to < 8%) without severe hypoglycaemia], 27.7 [HbA1c 64 to < 75 mmol/mol (8% to < 9%) without severe hypoglycaemia] and 40.5 [HbA1c ≥ 75 mmol/mol (≥ 9%) without severe hypoglycaemia]. Multivariate-adjusted hazard ratios (95% confidence intervals) for fractures were 2.24 (1.56, 3.21) in those with multiple episodes of severe hypoglycaemia, and 1.42 (1.04, 1.95) in those with HbA1c ≥ 75 mmol/mol (≥ 9%) without severe hypoglycaemia, compared with those with HbA1c < 53 mmol/mol (< 7%) without severe hypoglycaemia. CONCLUSIONS Both severe hypoglycaemia and poor glycaemic control were significantly related to an increased risk of fracture in people with type 2 diabetes, although severe hypoglycaemia conferred a stronger risk.

Abstract
A 48-year-old man with a pulmonary artery aneurysm was referred to our hospital. Enhanced computed tomography revealed an aneurysm extending from the main trunk to the bilateral pulmonary branch (maximum diameter 6.4 cm) of the artery. Echocardiography revealed moderate pulmonary valve (PV) regurgitation with right ventricle dilatation. Surgery was indicated because of the pulmonary aneurysm and dyspnea on exertion due to moderate PV regurgitation. Intra-operatively, two cusps were found to be normal in shape, whereas a third left-facing cusp was thick and resembled a small ridge. Therefore, we created one neo-cusp with autologous pericardium using a custom-made template and sutured it along a new, predetermined annulus. We then replaced the pulmonary aneurysm with a T-shaped artificial graft. Postoperative echocardiography showed satisfactory movement of the neo-cusp without pulmonary regurgitation and reduced right ventricular size.

Abstract
BACKGROUND Wire-loop lesion (WL) is one of the active lesions of lupus nephritis (LN). However, few reports have focused on the clinicopathological relationships of WL to serological immune abnormality and renal prognosis. METHODS We enrolled 126 Japanese LN patients subjected to renal biopsy in 11 hospitals from 2000 to 2018. In patients with class III or IV of the International Society of Nephrology/Renal Pathology Society classification, we retrospectively compared clinicopathological findings between those with WL (WL+ group) and without WL (WL- group) to detect factors associated with WL. Chronic kidney disease (CKD) was defined as an estimated glomerular filtration rate of <60 mL/min/1.73m2 for more than three months. We also compared these findings between those with CKD (CKD+ group) and without CKD (CKD- group) at the last visit to investigate factors associated with renal prognosis. RESULTS Of 126 patients, 100 (79.4%) were classified as class III or IV. WL was found in 36 (36.0%) of them. Although the renal function did not differ, the WL+ group had a higher titre of serum anti-dsDNA antibodies and lower serum complement 3 levels than the WL- group. Linear regression analysis revealed a significant association only between anti-dsDNA antibodies and WL (β = 0.27, 95% confidence interval (CI) 0.001-0.100, p = 0.01). Of these patients, 69 were tracked for 59.6 ± 55.1 months. Kaplan-Meier analysis showed no difference in renal prognosis between these groups. Next, the CKD+ group included 15 (22.1%) patients. They were older and had higher frequencies of hypertension and hyperuricaemia, serum creatinine (Cr) level, glomerulosclerosis, interstitial inflammation, interstitial fibrosis and tubular atrophy than the CKD- group at the time of renal biopsy. The frequency of WL was not significantly different. Cox regression analysis revealed significant associations of CKD with hypertension, hyperuricaemia, serum Cr level at the time of renal biopsy clinically and with tubular atrophy histologically. CONCLUSIONS WL was associated with serum anti-dsDNA antibodies but not with renal prognosis, suggesting that WL reflects immune abnormality but is not an independent factor predictive of renal prognosis in LN.

Abstract
Abstract
Background
Pressure-strain curve analysis (PS-curve) is novel method of echocardiographic evaluation for left ventricular (LV) systolic myocardial work including the effect of blood pressure. However, the prognostic value of PS-curve for prospective cardiac death in patients with congestive heart failure (CHF).
Purpose
To elucidate the prognostic value of PS-curve analysis for cardiac death in patients with CHF.
Methods
We enrolled 63 consecutive sinus-rhythm patients with CHF admission who were evaluated by PS-curve analysis before discharge (76.0±13.3 years, 39 males). Endpoint was set as all cardiac death.
Results
Observation period was median 327 days [25%: 91, 75%: 656 days], and the longest period was 1004 days. Five patients died for cardiac causes. Multivariate Cox regression analysis (stepwise regression) revealed diastolic blood pressure (BP) and global constructive work (GCW) were independent predictors (Hazard ratio: 0.854, 0.996, P value: 0.016, 0.019, respectively). ROC curve analysis demonstrated GCW ≤601 had high diagnostic performance for cardiac death (specificity 0.891, sensitivity 0.800, area under ROC 0.824). Kaplan-Meyer curve analysis indicated the group with GCW ≤601 was worse cardiac prognosis (Logrank P<0.001).

Conclusion
Pressure-strain curve analysis had powerful predictive value for cardiac death in patients with CHF.

Abstract
Abstract
Background
The serial electrocardiographic changes in patients following out-of-hospital cardiac arrest (OHCA) are unclear.
Purpose
To evaluate serial electrocardiographic changes and to predict all-cause mortality in patients following OHCA.
Methods
We retrospectively studied 101 OHCA patients (70±16 years, 49 male) who achieved a return of spontaneous circulation (ROSC) and survived for ≥3hours. Twelve-lead electrocardiograms (ECGs) were evaluated twice in each patient: initial-ECG, after achieving ROSC; and 2nd-ECG, after receiving the initial evaluation in the emergency room. Patients were divided into two groups: S-group, those surviving for 28 days, and D-group, those dying within 28 days. Multivariate Cox regression analyses were performed to predict the 28-day survival following OHCA. A Kaplan-Meier curve analysis for the 28 day mortality stratified by the QRS morphology and rhythm of initial-ECG was performed.
Results
Among variables of initial-ECG, there were significant differences between the group-S and group-D (table). Multivariate analysis with a step-wise regression demonstrated that age, lactate, and QRS duration of the initial-ECG were significant predictors of all-cause mortality (Odds ratio (OR): 1.04, 1.21, 1.02, p: 0.002, 0.001, 0.001, respectively). Kaplan-Meier analysis revealed that a complete right bundle branch block (CRBBB) of initial-ECG and presence of atrial fibrillation were associated with an increased risk of all-cause mortality (Picture).
