Abstract
Abstract
Background
Pulse wave velocity (PWV) is a non-invasive measure of arterial stiffness and a predictor of cardiovascular disease (CVD). Vascular calcification, especially coronary artery calcium (CAC) measured by computed tomography (CT), is one of the strongest predictors of CVD but requires radiation for measurement. PWV may be helpful to identify persons with vascular calcification who may benefit from formal assessment of vascular calcification with CT. However, the associations between PWV and vascular calcification across different vascular beds have not been fully investigated.
Purpose
The aims of this study were to quantify the association between PWV and calcification at different segments and to explore whether PWV can identify individuals with vascular calcification beyond traditional risk factors.
Methods
Among 1486 ARIC Study participants (mean age 79.3 [SD 4.2] years), we measured PWV by OMRON VP1000plus at the following segments: heart-carotid (hcPWV), heart-femoral (hfPWV), carotid-femoral (cfPWV), heart-ankle (haPWV), brachial-ankle (baPWV) and femoral-ankle (faPWV). Participants were stratified into four groups based on quartiles of each PWV measure. Dependent (i.e., outcome) variables were high calcium score (≥75th percentile of Agatston score by CT) of the following vascular beds (including valves): coronary arteries, aortic valve ring, aortic valve, mitral valve, ascending aorta, and descending aorta. We ran multivariable logistic regression models and assessed c-statistics as a measure of prediction discrimination.
Results
Only cfPWV was significantly positively associated with high CAC (adjusted odds ratio [OR] for the highest vs. lowest quartile: 1.73 [95% CI: 1.17–2.55]) (green dot in figure). The associations were overall most evident for descending aorta calcification, with significantly positive results for hfPWV (gold dot in figure), cfPWV (green dot), haPWV (emerald dot), and baPWV (blue dot). For example, adjusted OR for the highest vs. lowest quartile of cfPWV was 4.08 (2.70–6.24). hfPWV and cfPWV were significantly associated with mitral valve calcification as well. In contrast, faPWV (purple dots) was inversely associated with calcification of aortic valve ring, ascending aorta, and descending aorta. For descending aorta calcification, even the second highest quartile of the following measures demonstrated significant adjusted OR: hfPWV (3.21 [2.11–4.95]), cfPWV (2.11 [1.40–3.20]), and baPWV (1.75 [1.14–2.69]). Simultaneously adding cfPWV and hfPWV improved c-statistic for CAC (Δc-statistic 0.011 [0.0007–0.022]) and descending aorta calcification (0.035 [0.017–0.053]).
Conclusions
The associations of PWV with vascular calcification varied substantially across segments, with descending aorta calcification most closely linked to PWV measures and cfPWV most robustly associated with calcification of multiple vascular beds. cfPWV and hfPWV, together, improved discrimination of high CAC beyond traditional risk factors.

Abstract
Abstract
Background
The 2021 ESC guideline on cardiovascular disease (CVD) prevention qualitatively categorizes moderate and severe chronic kidney disease (CKD) as high and very-high CVD risk status regardless of other factors like age and does not include estimated glomerular filtration rate (eGFR) and albuminuria in its algorithms, SCORE2 and SCORE2-OP, to predict CVD risk.
Purpose
To develop and validate an “Add-on” to incorporate CKD measures into these algorithms, using a validated approach.
Methods
In 3,054,840 participants from 34 datasets, we developed three Add-ons (eGFR only, eGFR + urinary albumin-to-creatinine ratio [ACR] [the primary Add-on], and eGFR + dipstick proteinuria) for SCORE2 and SCORE2-OP. We validated c-statistics and net reclassification improvement (NRI), accounting for competing risk of non-CVD death, in 5,995,067 participants from 33 different datasets.
Results
In the target population of SCORE2 and SCORE2-OP without diabetes, the CKD Add-on (eGFR only) and CKD Add-on (eGFR + ACR) improved c-statistic by 0.006 (95% CI 0.005–0.008) and 0.018 (0.012–0.024), respectively, for SCORE2 and 0.012 (0.009–0.015) and 0.023 (0.013–0.032), respectively, for SCORE2-OP. Similar results were seen when we included individuals with diabetes and tested the CKD Add-on (eGFR + dipstick). In 57,485 European participants with CKD, SCORE2 or SCORE2-OP with a CKD Add-on showed a significant NRI (e.g., 0.100 [0.062–0.138] for SCORE2) compared to the qualitative approach in the ESC guideline.
Conclusion
Our Add-ons with CKD measures improved CVD risk prediction beyond SCORE2 and SCORE2-OP. This approach will help clinicians and patients with CKD refine risk prediction and further personalize preventive therapies for CVD.

Abstract
Abstract
Background
Aortic stenosis (AS) is characterized by endothelial dysfunction (ED), inflammatory cell infiltration, myofibroblastic and osteoblastic differentiation. Subclinical leaflet thrombosis was recently linked to higher rates of stroke and transient ischemic attack after transcatheter aortic valve implantation (TAVI). Procoagulant microparticles (MPs) are associated with ED, inflammation and clot formation. There is limited evidence regarding intra-valvular MPs content and their potential biological effects. This question is particularly relevant in TAVI in which the residing native valve could constitute a source of thrombotic activity enhancing leaflet thrombosis and valve dysfunction.
Purpose
Therefore, we hypothesized that MPs trapped within the native aortic valve contribute to valvular dysfunction including enhanced thrombogenicity.
Methods
Human valves were collected from patients undergoing surgical valve replacement for AS or aortic insufficiency (AI). Pro-thrombotic, pro-inflammatory, and ED markers were identified in the calcified vs non-calcified part of the valves by Western-blot. Calcium content was measured through colorimetric method. MPs were extracted from human pathological valves, and quantified through their prothrombinase activity. Primary cultures of porcine valvular endothelial cells (VEC) were treated with the MPs (10 nmol/L) or thrombin (1U/ml) for 24hrs. Phenotypic change was appreciated through gene expression pattern assessed by RT-qPCR. IL-8 secretion was measured by ELISA.
Results
The phenotype of the AS valve was characterized through increased expression of thrombogenic (tissue factor, thrombomodulin, PAI-1), adhesive (VCAM-1, ICAM-1) and inflammatory (COX-1, COX-2) molecules in the calcified part of the valve. Moreover, MPs content was increased in the calcified vs non-calcified part of the valve or AI valves. MPs levels was correlated with valvular calcium content (R=0.3862: p<0.001). Tissue factor was increased in MPs extracted from AS vs AI. The biological effect of MPs was tested on VEC in-vitro. Results showed dramatic increase in expression of inflammatory cytokines (CXCL10, CCL11, CXCL8, MCP1) adhesion molecules (VCAM-1, ICAM-1, SELP, SELE) and proangiogenic factors (VEGFR2, ANGPTL4) in VEC exposed to MPs (24h) from AS vs AI. Enhanced secretory phenotype was evidenced through IL-8 determination in the supernatant of VEC stimulated with MPs from AS valve.
Conclusion
Calcified aortic valve is a potent reservoir of MPs, acting as a pro-thrombogenic source per se and promoting a switch of VEC phenotype toward prothrombotic, proinflammatory and proangiogenic pattern. These data suggest that MPs released from the native valve constitute an important source of mediators involved in enhanced thrombogenicity and valvular remodeling.

Abstract
Abstract
Introduction
Heart transplantation is a life-saving surgical procedure for patients with end-stage cardiac dysfunction, however, such procedures are usually at risk of rejection due to acute inflammatory activation. While such inflammatory induction leaves the newly transplanted heart at risk of functional and structural remodeling subsequent to oxidative damage, current anti-inflammatory treatment options expose the patient to an elevated risk for adverse reactions in addition to absence of cardio-protective effects. Therefore, novel therapies with anti-inflammatory and cardio-protective dual effects are needed. Recently, our group has reported that low-grade inflammation is associated with upregulation of SGLT1/2 in arteries of human with cardiovascular diseases. Yet, the role and function of SGLT2 in human cardiac tissue remains poorly understood.
Aim
This study focuses on the expression pattern of SGLT1/2 in cardiac biopsies of heart transplanted patients and aim to identifying their functional impact.
Methods
Routine endomyocardial Biopsies (23) were performed for the detection of acute rejection heart transplanted patients (less than 2 years) at our University Hospital. Gene expression levels were assessed using RT-qPCR, the in situ tissue localization of proteins by immunofluorescence staining, and the level of oxidative stress by dihydroethidium staining.
Results
Gene expression analysis revealed strong inflammatory reaction in 5 samples indicated by at least 20-fold higher levels of mRNA of IL1B, IL6, TNFA and CD68 compared to the other 18 samples and concomitant with high expression levels of SLC5A1, SLC5A2, AT1R, CYBA, NCF1, ICAM1, VCAM1, MMP2, MMP9 and TGFB1 in contrast to low levels of NOS3. In addition, increased levels of oxidative stress were observed in the same biopsies, which were diminished by the antioxidant N-acetylcysteine (NAC), NADPH oxidase inhibitor (VAS-2870), TNF-α receptor neutralizing antibody (infliximab), ACE inhibitor (perindoprilat), AT1R antagonist (losartan), dual SGLT1/2 inhibitor (sotagliflozin) and selective SGLT2 inhibitor (empagliflozin) with inhibitory effects reaching up to 80%. Immunofluorescence staining indicated signals for nitro-tyrosine, TNF-alpha, SGLT1 and 2 in several samples.
Conclusion
These findings indicate that both isoforms SGLT1 and SGLT2 are expressed in the transplanted human heart and suggest a pattern of expression associated with pro-inflammatory response. They further indicate a potential protective effect of SGLT2 inhibitors in transplanted hearts through mitigating oxidative stress and hence providing a possible novel therapy for heart transplantation recipients to preserve the heart function.

Abstract
Abstract
Background
In clinical practice, factors known to be associated with cardiovascular disease (CVD) like albuminuria, education level, or coronary calcium score are not directly incorporated in cardiovascular risk prediction models. The aim of the current study was to quantify the added value of potential risk modifying characteristics when added to the SCORE2 algorithm for individuals without diabetes mellitus (DM) or prior CVD.
Methods and results
Individuals without previous CVD or DM were included from the ARIC, MESA, EPIC-NL and HNR studies (n=46,285) in whom 2,177 CVD events and 2,062 non-cardiovascular deaths were observed over exactly 10.0 years of follow-up. The effect of each possible risk modifying characteristic was derived using Fine and Gray models that included an offset term for the SCORE2 linear predictor. The risk modifying characteristics were applied to individual predictions using the “naïve approach”, which modifies predicted risks based on the population prevalence and the SHR of the relevant predictor. Subdistribution hazard ratios are presented in the table. External validation was performed in the CPRD cohort (UK, n=518,015, 12,675 CVD events). In the external validation, adjustment of SCORE2 predicted risks with both single and with all available risk modifiers did not negatively affect calibration (see figure) and led to a modest increase in discrimination (C-index 0.742 [95% CI 0.737–0.746] versus unimproved SCORE2 risk C-index 0.737 [95% CI 0.732–0.741]). The net reclassification index or adding all these predictors was +0.032 (95% CI 0.025; 0.028) for future events and −0.008 (95% CI −0.009; −0.007) for future non-events. The coronary calcium score was found to the single strongest added predictor.
Interpretation
The current analysis presents a method on how to integrate possible risk modifying characteristics that are not included in existing CVD risk models for the prediction of CVD event risk in apparently healthy people. This flexible methodology improves the accuracy of predicted risks and increases applicability of prediction models for individuals with additional risk known modifiers

Abstract
Abstract
Background
Tafamidis is a stabilizer of transthyretin, specifically designed to decrease or prevent amyloidogenesis, and improves prognosis in patients with transthyretin amyloid cardiomyopathy (ATTR-CM). However, clinical coarse, selection of appropriate patients and monitoring therapeutic effect of tafamidis remained unclear.
Purpose
The aim of this study was to clarify the patients' characteristics, clinical coarse, and clinical outcomes of tafamidis in patients with ATTR-CM and to evaluate prognostic factors and changes in clinical data over time.
Methods
We evaluated consecutive 180 patients with ATTR-CM considering tafamids treatment. A total of 107 patients had tafamidis treatment (tafamidis treatment group) and 65 patients did not treat with tafamidis (treatment naïve group). The remaining 8 patients were preclinical. Clinical data were obtained at the consideration of tafamidis treatment. We divided the following the cut-off values of high-sensitivity cardiac troponin T (hs-cTnT); >0.05 ng/mL, B-type natriuretic peptide (BNP); >250 pg/ml, and estimated glomerular filtration rate (eGFR); <45 mL/min/1.73 m2 and calculated the score by adding 1 point if increased or decreased by more than the cut-off value. We divided patients into a low score group (0–1 point) and high score group (2–3 points).
Results
All of study patients in the tafamidis treatment group were wild-type ATTR-CM. Compared to tafamidis treatment group, tafamidis naïve group were significantly older (75.6±5.3 vs. 82.8±4.6 years; p<0.01), female dominant (8% vs. 28%; p<0.01), increased BNP levels (median 209 vs 306 pg/ml; p<0.01), and lower haemoglobin levels (14.1±1.8 vs. 12.4±1.8 g/dl; p<0.01). Tafamidis treatment group was significantly favourable clinical outcomes competed to treatment naïve group (p<0.05; log rank test). According to multivariate logistic regression analysis, prior heart failure hospitalization (hazard ratio [HR]: 5.93, 95% confidence interval [CI]: 1.25–28.03, p=0.03) and high score group (HR: 1.56, 95% CI: 0.37–7.25; <0.01) were the significant poor prognostic factors in tafamids treatment group. Among tafamidis treatment group, Hs-cTnT levels were significantly decreased after 12 months tafamidis treatment (0.055 [0.037–0.082] vs. 0.044 [0.033–0.077]; p<0.01) instead of no significant differences in BNP and significant decline of eGFR levels. There were no significant changes over time in the echocardiographic parameters after 12 months, and native T1 and extracellular volume fraction obtained by cardiac magnetic resonance in a limited number of patients.
Conclusion
The prognosis of ATTR-CM patients treated with tafamidis was favorable compared to tafamidis naïve group. Patient stratification combined with biomarkers predicted favorable prognosis in patients with tafamidis treatment. Hs-cTnT may be a useful maker for evaluating the therapeutic effect by tafamidis.

Abstract
Abstract
Background
Transthyretin amyloid cardiomyopathy (ATTR-CM) is a progressive and infiltrative disease caused by the deposition of insoluble transthyretin (TTR) amyloid fibrils in the myocardium, which leads to cardiomyopathy characterized by increased ventricular wall thickness and diastolic dysfunction. TTR amyloid fibrils are performed by dissociation of the tetrameric TTR into monomers and misfolding and misassemble into insoluble fibrils. Tafamidis stabilizes the tetramers and inhibits the TTR monomerization, leads to inhibit the formation and deposition of TTR fibril. Clinical trials suggested tafamidis could improve prognosis by slowing the progression of amyloidosis. Evaluation of serial measurement echocardiographic findings by tafamidis treatment is important, but these data has not been fully revealed.
Purpose
The aim of study was to evaluate the change of echocardiographic parameter in patients with ATTR-CM received tafamidis for 12 months. Especially in strain echocardiogram, global longitudinal strain (GLS) has reported to be associated with prognosis, and apical sparing pattern, which longitudinal strain (LS) in the basal and middle segments is more severely impaired than the apical segments, is specific finding in ATTR-CM.
Method
Echocardiographic findings before and 12 months were compared in 68 patients with ATTR-CM who started a new prescription of tafamidis and 18 tafamidis naïve patients with ATTR-CM patients who underwent echocardiography annually prior to the approval of tafamidis.
Result
Among tafamidis treatment group, echocardiographic parameters were not significant changes before and after 12 months tafamidis treatment [left ventricular ejection fraction (LVEF): 49.6±10.6% vs. LVEF: 49.9±10.7% (p=0.767), interventricular septum diameter (IVSd):16.0±2.3mm vs 15.7±2.1mm (p=0.241), left ventricular posterior wall diameter (LVPWd):16.1±2.5mm vs 16.1±2.5mm (p=0.964), GLS: −8.4±2.7% vs −8.2±2.8% (p=0.419), LS at base: −4.6±2.6% vs −4.2±2.4% (p=0.291), LS at middle: −6.9±3.6% vs −6.9±2.8% (p=0.922), LS at apical:-12.7±4.2% vs −12.4±4.4% (p=0.615). Among tafamidis naïve group, these parameters remained almost unchanged in 12 months as well, except for GLS and LS at apical. LS at apical showed a significant impairment. [LVEF: 53.8±9.2% vs 51.7±9.3% (p=0.244), IVSd: 15.5±2.3mm vs 16.0±1.8mm (p=0.321), LVPWd: 15.4±2.3mm vs 15.9±2.3mm (p=0.267), GLS: −10.4±2.4% vs −9.0±2.9% (p=0.065), LS at base: −5.0±2.7% vs −5.1±2.9% (p=0.865), LS at middle: −8.9±3.1% vs −8.5±3.5% (p=0.565), LS at apical: −15.4±4.0% vs −12.6±4.4% (p=0.02); Table 1]
Conclusion
We evaluated changes in echocardiographic findings with tafamidis treatment for 12 months. The echocardiographic parameters did not change over the course of 12 months, but the decrease in LS at apex observed in the tafamidis naïve group.Segmental LS could reflect a slight progression of cardiac amyloidosis and the short-term effects of tafamidis.

Abstract
We measured the concentrations and determined the distribution of the stable isotope 127I in the marine organisms. Marine fish were collected from the Pacific Ocean near Aomori, Japan. The mean 127I concentrations in the muscle of marine fish ranged from 0.67 μg g-1-wet weight (ww) in cherry salmon to 0.84 μg g-1-ww in fat greenling. Among the tissues measured, the muscle showed the lowest levels of 127I in all fish species. The highest 127I concentration in the tissues of marine fish was observed in the ovary of fat greenling. The mean 127I concentration in the of Japanese scallop ranged from 0.06 μg g-1-ww in adductor muscle to 5.49 μg g-1-ww in mid-gut gland. The 127I concentrations in seaweeds were 67 μg g-1-dry weight (dw) in sea lettuce and 1783 μg g-1-dw in kombu. Thus, the distribution of 127I concentration in marine organisms varied considerably depending on the tissue.

Abstract
Abstract
Background
Despite of the development of endovascular therapy (EVT), the frequency of target lesion revascularization (TLR) after EVT in patients with critical limb ischemia (CLI) is still high. Recent histrogical study suggested the possibility of thromboembolic phenomenon in the development of CLI; however, there is few monitoring system of total thrombogenicity in perioperative period of EVT in CLI patients. The total thrombus-formation analysis system (T-TAS), a novel system for quantitatively analyzing thrombus formation using microchips with thrombogenic surfaces (collagen plus tissue factor, atheroma [AR]-chip), is validated and can evaluate the total thrombogenicity.
Purpose
To investigate the utility of T-TAS parameters in predicting TLR after EVT in CLI patients.
Methods
We analyzed 27 CLI patients (45 lesions; aortoiliac 20%, femoropopliteal 40%, infrapopliteal 40%) who underwent EVT at our institution between January 2018 and December 2020. Patients undergoing hemodialysis were excluded. Blood sample was collected on the day of EVT and was used in T-TAS to compute the thrombus formation area under the curve (AUC; AUC for the first 30 minutes for AR tested at flow rate of 10 lL/min [AR10-AUC30]). We investigated the relationship between the AR10-AUC30 level and the occurrence of clinically-driven TLR, and the predictors of TLR among CLI patients.
Results
Study population had a mean age of 77 years, and 56% were male. During the follow-up period (mean 1.0±0.7 years), 11 lesions (24%) required clinically-driven TLR. The AR10-AUC30 level was significantly higher in patients requiring TLR than those without TLR (1783±121 vs. 1587±205; p<0.01). The frequency of TLR significantly increased in association with a tertile of the AR10-AUC30 level (Figure 1, p for trend=0.003). As shown in Figure 2, univariate logistic regression analysis demonstrated male sex and the third tertile of the AR10-AUC30 level compared to its first or second tertiles were significantly associated with TLR in patients with CLI, whereas platelet count, PT-INR, APTT, and atherosclerotic risk factors including glycated hemoglobin, low-density lipoprotein cholesterol, and renal function were not. Multivariate logistic regression analysis also revealed that the AR10-AUC30 level ≥1707 (=its third tertile) as an independent predictor for TLR, even after adjusted by age and sex (OR=6.28, 95% CI=1.18–33.3, p=0.03).
Conclusions
In patients with CLI, the AR10-AUC30 level measured by the T-TAS may be a potential predictor to identify the high-risk patients requiring TLR after EVT. This finding suggests the hypercoagulability in CLI patients and that an anticoagulant agent following EVT may be useful in preventing a restenosis in CLI patients. Further study with a larger sample size is warranted to validate this finding.

Abstract
Abstract
Introduction
Patients with atrial fibrillation (AF) are likely to have multiple co-morbidities and receive anticoagulants after TAVR, which lead to a poor prognosis including bleeding events. Closure time adenosine diphosphate (CT-ADP) is a primary hemostasis point-of-care test used as a surrogate marker of high molecular weight (HMW) multimers defect of Von Willebrand factor (VWF). Our prior studies suggest that prolongation of CT-ADP (>180 seconds) after TAVR is a major determinant of early and late major/life-threatening bleeding complications (MLBCs).
Purpose
To evaluate the impact of post-procedural CT-ADP >180sec on bleeding events in AF patients.
Methods
We included 878 patients from our prospective TAVR registry between 2010 and 2019. Bleeding complications were assessed according to the VARC-2 (Valve Academic Research Consortium-2) criteria. Major adverse cardiac and cerebrovascular events (MACCE) was defined as a composite of all-cause death, myocardial infarction, stroke, and heart failure hospitalization within 1-year after TAVR. Ongoing primary haemostasis disorder was defined by post-procedure CT-ADP >180sec. Primary endpoint was the occurrence of MLBCs during the first year and the second endpoint was 1-year MACCE.
Results
Patients with AF had a higher incidence of all-cause mortality (15% vs. 8%, p=0.002), MACCE (29% vs. 20%, p=0.002), and MLBCs (20% vs. 12%, p=0.001) within 1-year compared to non-AF patients. When the cohort was split into 4 subgroups according to AF and CT-ADP >180sec, patients with AF and CT-ADP >180sec had the highest risk of MLBCs (log-rank test; p<0.001) (Figure). Multivariate Cox regression analysis confirmed that the patients with AF and CT-ADP >180sec had 4.6-fold higher risk of MLBCs within 1 year compared to non-AF patients with CT-ADP ≤180sec (hazard ratio: 4.60; 95% confidence interval: 2.18 - 9.68; p<0.001).
Conclusion
Among TAVR patients, AF with post-procedural CT-ADP >180 sec was identified as a strong independent predictor of MLBCs at 1-year follow-up. Our study suggest that persistent primary haemostasis disorders contribute to a higher risk of bleeding events particularly in AF patients and may be considered for a tailored and risk-adjusted antithrombotic therapy after TAVR.

Abstract
Abstract
Background
Although wild-type transthyretin amyloid cardiomyopathy (ATTRwt-CM) was previously considered a rare disease, recent diagnostic imaging modalities have revealed that it is considerably underdiagnosed among elderly patients with heart failure. The severity of CM is thought to be related to the extent of amyloid deposition in heart.
99mTc-labeled pyrophosphate (99mTc-PYP) scintigraphy, cardiovascular magnetic resonance (CMR), global longitudinal strain (GLS) provide diagnostic and prognostic information in ATTRwt-CM. However, the relevance of these imaging modalities and their association with cardiac amyloid load has not been fully evaluated.
Purpose
The aim of study was to elucidate the associations between pathological amyloid load and cardiac retention evaluated by 99mTc-PYP scintigraphy, CMR, GLS in patients with ATTRwt-CM.
Method
Cardiac amyloid load was calculated as (amyloid deposition area/ total myocardium area)×100 using endomyocardial biopsy specimen. Cardiac retention was quantified by heart to contralateral (H/CL) ratio by 99mTc-PYP scintigraphy. Native T1 and extracellular volume (ECV) were obtained by CMR. GLS was analyzed using the 2D echo at the time of diagnosis.
Result
The mean cardiac amyloid load was 23.0±15.2% (n=57) and correlation with H/CL ratio (1.94±0.36 n=57), native T1 (1426.7±52.5 n=57), ECV (57.9±12.9 n=54), GLS (−9.1±2.4 n=57) were positive (r=0.375 p=0.004, r=0.496 r=0.304 p<0.001, r=0.304 p=0.025, r=0.473 p<0.001).
Conclusion
Increased cardiac amyloid load correlated with an increased 99mTc-PYP positivity, native T1, ECV, and an impaired GLS. These results suggest that imaging parameters may reflect histological and functional changes due to amyloid deposition in the myocardium.

Abstract
Abstract
Aims
A significant male predominance has been reported in wild-type transthyretin amyloid cardiomyopathy (ATTRwt-CM). In other words, the female ATTRwt-CM may be overlooked and gender differences in ATTRwt-CM remain unclear. This study aims to examine gender differences in clinical characteristics and diagnostic approaches in ATTRwt-CM.
Methods and results
We retrospectively evaluated 171 consecutive ATTRwt-CM patients diagnosed at our university hospital between December 2002 and December 2020. Twenty-two patients (12%) were women. Women were significantly older at diagnosis (77.3 years vs. 83.3 years; P<0.001) and had a higher advanced New York Health Association functional class (2.23±0.70 vs. 2.57±0.81; P=0.04) than men. In echocardiography, mean interventricular septum diameter was less thick (15.8 mm vs. 14.5 mm; P=0.03) and ejection fraction was preserved (51.7% vs. 57.7%; P=0.08) in women. The mean heart-to-contralateral ratio obtained using 99mTc-labeled pyrophosphate (99mTc-PYP) was significantly lower in women than in men (1.89 vs. 1.64; P=0.001). There was no significant gender difference in high-sensitivity median cardiac troponin T levels at diagnosis (0.055 ng/mL vs. 0.069 ng/mL; P=0.30) or history of carpal tunnel syndrome (57% vs. 55%; P=0.93) and electrocardiograms findings. However, the median B-type natriuretic peptide level was significantly higher (254 pg/mL vs. 434 pg/mL; P=0.02) in women. Moderate to severe aortic stenosis was more frequently observed in women (5% vs. 50%; P<0.001). Histological (78% vs. 59%; P=0.07) and genetic confirmation (78% vs. 59%; P=0.003) of ATTRwt-CM were not performed in women.
Conclusion
Women with ATTRwt-CM were predominantly octogenarians, less hypertrophic, and had weaker cardiac uptake of the 99mTc-PYP tracer than men with ATTRwt-CM. These characteristics contribute to the underdiagnosis of ATTRwt-CM in women. The diagnosis of ATTRwt-CM in women is challenging. Therefore, we must be familiar with the clinical characteristics of women with ATTRwt-CM.

Abstract
Abstract
Background
Selective sodium-glucose cotransporter 2 (SGLT2) inhibitors have shown cardiovascular protection independently of glycemic control. Angiotensin II (Ang II) and H2O2 induced the expression of SGLT1 and 2 in cultured endothelial cells and isolated arteries to promote oxidative stress and endothelial dysfunction. However, the expression level and role of SGLT1 and 2 in human arteries remain poorly studied.
Purpose
This study examined the expression level of SGLT1 and 2 in the human internal mammary artery (IMA) obtained from bypass surgery patients, and, if so, determined the underlying mechanism and function.
Methods
IMAs were obtained from 40 bypass surgery patients (age 45 to 82). The expression level of target factors was assessed by Western blot analysis, immunofluorescence staining and RT-PCR, and the level of oxidative stress using dihydroethidium staining. Human kidney was used as a control tissue known to express SGLT1 and 2. Porcine coronary artery endothelial cells (CAEC) were cultured and studied at passage 1.
Results
Western blot analysis of 40 IMA samples indicated a high level of both SGLT1 and 2 in 16 and 17 IMAs, an intermediate level in 8 and 6 IMAs, and a low one in 16 and 17 IMAs, respectively. Immunofluorescence staining of IMA sections indicated that SGLT1 and 2 immunofluorescence signals were observed predominantly in the intima thickening and the media. The expression levels of SGLT1 and 2 were associated with p-p65 NF-kB signals but not angiotensin-converting enzyme (ACE), AT1R, MCP-1, VCAM-1. IMAs with a high expression level of SGLT1 and 2 had a high level of ROS throughout the arterial wall including the intima thickening and endothelium, which was inhibited by the antioxidant N-acetylcysteine, the ACE inhibitor perindoprilat, the AT1R antagonist losartan, and also by the dual SGLT1 and 2 inhibitor sotagliflozin and the selective SGLT2 inhibitor empagliflozin. Pro-inflammatory cytokines mRNA levels of IL-1β, TNF-α and IL-6 were detected in IMAs. Exposure of CAEC to either TNF-α, IL-1β or IL-6 caused a concentration-dependent upregulation of SGLT1 and 2.
Conclusion
The present findings indicate that SGLT1 and 2 expression is observed in some but not all IMAs of bypass surgery patients predominantly in the media, the intima thickening and the endothelium. High expression levels of SGLT1 and 2 are associated with NF-kB activation and oxidative stress that is prevented by a selective SGLT2 inhibitor and by a dual SGLT1/2 inhibitor. Since pro-inflammatory cytokines triggered SGLT1 and 2 expression in endothelial cells, the inflammatory burden of patients appears to be an important trigger regulating SGLT1/2 expression and the subsequent pro-oxidant response prompting pro-inflammatory and pro-thrombotic responses.

Abstract
Abstract
Introduction
Sodium-glucose co-transporter 2 (SGLT2) inhibitors have been shown to reduce the risk of cardiovascular events independently of glycemic control. The possibility that SGLT2 inhibitors improve endothelial regeneration and vascular restenosis is unknown.
Purpose
To examine whether dapagliflozin, a selective SGLT2 inhibitor, could prevent neointima thickening induced by balloon injury and, if so, to determine the underlying mechanisms. The effect of dapagliflozin was compared to that of losartan, an angiotensin type 1 receptor (AT1R) antagonist.
Methods
Saline, dapagliflozin (1.5 mg/kg/day), or losartan (30 mg/kg/day) were administered orally for 5 weeks to male Wistar rats. Balloon injury of the left carotid artery was performed 1 week after starting the treatment and sacrificed 4 weeks later. Vascular reactivity was assessed on left (injured) and right (healthy) carotid artery rings. The extent of neointima was assessed by histomorphometric analysis, changes of target factors by immunofluorescence, RT-qPCR and histochemistry.
Results
Dapagliflozin and losartan treatments reduced neointima thickening by 32% and 27%, respectively. Blunted contractile responses to phenylephrine and relaxations to acetylcholine and down-regulation of eNOS were observed in the injured artery. These effects were not modified by the dapagliflozin or the losartan treatments. RT-qPCR investigations indicated an increased in gene expression of inflammatory (IL-1beta, ITGAM, VCAM-1), oxidative (p47phox, p22phox) and fibrotic (TGF-beta1) markers and a decreased of eNOS in the injured carotid. However, these changes were not affected by the pharmacological treatments. By contrast, significant increased levels of AT1R angiotensin receptor and NTPDase1 (CD39) ectonucleotidase were observed in the restenotic carotid artery of the dapagliflozin group. Histochemical analysis evidenced important NTPDase1 activity in the neointima.
Conclusions
Dapagliflozin effectively reduced neointimal thickening. As the contribution of AT1R and P2Y2 ATP receptor in smooth muscle cell proliferation and neointima formation has been reported in the literature, the present data suggest that dapagliflozin prevents restenosis through interfering with angiotensin and/or extracellular nucleotides signaling. SGLT2 transporter represent potential new target for limiting vascular restenosis.

Abstract
INTRODUCTION The aim of this study was to compare body weight loss between postoperative intermaxillary fixation with metal wire and elastic traction and to investigate factors related to body weight loss after orthognathic surgery. MATERIALS AND METHODS Subjects were 59 patients with dentofacial deformity, comprising 31 patients treated with intermaxillary fixation (IMF) and 28 patients treated with elastic traction without IMF (ELT) just after surgery. Body weight loss was measured at 1 week (T1) and 2 weeks (T2) after surgery. Body weight loss was compared between IMF and ELT, and factors related to body weight loss were statistically analyzed. RESULTS Body weight loss ratio was significantly increased in IMF (2.6%) rather than in ELT (1.4%) at T1, but only tended to be increased in both groups at T2, showing no statistical difference. Body weight loss ratio was significantly increased at T2 compared to T1 in both groups. Body weight loss was significantly greater at T2 than at T1. CONCLUSION Both IMF and ELT cause body weight loss after orthognathic surgery, but IMF causes body weight loss earlier than ELT and increased early body weight loss increases continuous body weight loss after orthognathic surgery.

Abstract
Background Systemic coagulation activation and thrombotic complications are frequent among critically ill patients with COVID-19. Limited data are available in non-intensive care unit (ICU) patients. Purpose To determine the incidence, risk factors and prognosis of venous thromboembolism (VTE) in non-ICU COVID-19 patients. Methods We studied consecutive COVID-19 patients admitted to general ward at Strasbourg Hospital, France (25.02.2020–19.04.2020). The primary outcome was any VTE complication. The secondary outcome was the composite of death or transfer to ICU. Results Among the 289 patients included (62.2 ± 17.0 years, 59.2% male), VTE occurred in 49 (17.0%). Padua prediction score for VTE was similar between VTE and non-VTE patients. VTE imaging tests were performed in 100 (34.6%) patients and VTE diagnosed in median 7 (3–11) days after admission. On-admission, time from symptom onset to admission (OR 1.07, CI 95% [1.00–1.16], P = 0.045), Improve score (OR 1.37, [1.02–1.83], P = 0.032), leukocyte count (OR 1.16, [1.06–1.27], P = 0.001) and lack of thromboprophylaxis (OR 27.85, CI 95% [9.35–82.95], P < 0.001) were independent predictors of VTE. The incidence of the composite of death or ICU transfer was 31.0% and more frequent among patients with VTE (47.9% vs. 27.9%, P = 0.01). Fever (OR 5.37, CI 95% [1.44–19.97], P = 0.012), VTE (OR 3.44, CI 95% [1.63–7.25], P = 0.001), lymphopenia (OR 0.32, 95% CI [0.15–0.71]; P = 0.005) and extent of COVID-19 evaluated by chest CT severity (OR 1.56, 95% CI [1.12–2.16]; P = 0.007) were independently associated with in-hospital death or transfer to ICU (Table 1, Fig. 1). Conclusions The 17.0% incidence of VTE in non-ICU patients with COVID-19 was associated with worse outcomes. Given the high incidence of VTE in ward patients, there is an urgent need to investigate the optimal anticoagulation regimen.

Abstract
Abstract
Introduction
Current recommendations support short-term dual antiplatelet therapy (DAPT) for patients undergoing transcatheter aortic valve replacement (TAVR) despite no relevant study exploring the extent of platelet inhibition by clopidogrel.
Purpose
To assess whether P2Y12 inhibition by clopidogrel as evaluated by vasodilator-stimulated phosphoprotein flow cytometry test (VASP-FCT) impacts 1-year clinical outcomes in patients undergoing TAVR.
Methods
Patients were included in a prospective registry between February 2010 and May 2019. VASP-FCT was assessed 24h after the procedure. Responder to clopidogrel was defined by a platelet reactivity index ≤50%.
Results
Of 640 patients who underwent TAVR with preprocedural clopidogrel therapy, we enrolled 491 patients for whom VASP data were available. Responders were identified in 22% (n=110) of patients and low responders were 78% (n=381) of patients. Low body mass index, active cancer, and clopidogrel on admission were found to be independent predictors of responder. Mean transaortic pressure gradient was lower in the responder group at 1-month post-TAVR (9.9±4.4 mmHg vs. 11.2±5.8 mmHg, p=0.03) but was similar at 1-year (11.5±6.2 mmHg vs. 11.9±7.4 mmHg, p=0.74). By multivariate Cox regression analysis, patients responding to clopidogrel (hazard ratio [HR]: 2.19; 95% confidence interval [CI]: 1.04 to 3.64; p=0.04), prior PCI (HR: 2.12; 95% CI: 1.07 to 4.37; p=0.03), and mean transaortic pressure gradient at baseline (HR: 0.07; 95% CI: 0.01 to 0.70; p=0.02) were identified as independent predictors of 1-year adverse clinical outcomes, including all-cause death, myocardial infarction, stroke, and heart failure hospitalization.
Conclusions
Appropriate P2Y12 inhibition by clopidogrel is a major determinant of adverse clinical events after TAVR. In sum, the present data challenges the need of DAPT as a standard therapy during TAVR.

Abstract
Abstract
Background
Recent insights have emphasized the importance of myocardial and systemic inflammation in Takotsubo Syndrome (TTS).
Objective
In a large registry of unselected patients, we sought to evaluate whether residual high inflammatory response (RHIR) could impact cardiovascular outcome after TTS.
Methods
Patients with TTS were retrospectively included between 2008 and 2018 in three general hospitals. 385 patients with TTS were split into three subgroups, according to tertiles of C-reactive protein (CRP) levels at discharge (CRP<5.2 mg/l, CRP range 5.2 to 19 mg/l, and CRP>19 mg/L). The primary endpoint was the impact of RHIR, defined as CRP>19 mg/L at discharge, on cardiac death or hospitalization for heart failure.
Results
Follow-up was obtained in 382 patients (99%) after a median of 747 days. RHIR patients were more likely to have a history of cancer or a physical trigger. Left ventricular ejection fraction (LVEF) at admission and at discharge were comparable between groups. By contrast, RHIR was associated with lower LVEF at follow-up (61.7 vs. 60.7 vs. 57.9%; p=0.004) and increased cardiac late mortality (0% vs. 0% vs. 10%; p=0.001). By multivariate Cox regression analysis, RHIR was an independent predictor of cardiac death or hospitalization for heart failure (hazard ratio: 1.97; 95% confidence interval: 1.11 to 3.49; p=0.02).
Conclusions
RHIR was associated with impaired LVEF recovery and was evidenced as an independent factor of cardiovascular events. All together these findings underline RHIR patients as a high-risk subgroup, to target in future clinical trials with specific therapies to attenuate RHIR.

Abstract
Abstract
Background
Selective sodium-glucose cotransporter 2 (SGLT2) inhibitors have shown cardiovascular protection in type 2 diabetes patients with established cardiovascular disease independently of glycemic control. Angiotensin II (Ang II) and H2O2 have been shown to be strong inducers of the expression of SGLT2 and 1 in endothelial cells promoting oxidative stress and endothelial dysfunction.
Purpose
This study examined the cardiovascular protective effect of empagliflozin (empa) in a normoglycemic experimental model of hypertension in the rat.
Methods
Male Wistar rats received empa (30 mg/kg/day) provided in the diet for 5 weeks. After 1 week, rats underwent sham surgery (sham rats) or surgery with implantation of an osmotic mini-pump infusing Ang II (0.4 mg/kg/d) for 4 weeks. Systolic blood pressure (SBP) was assessed by sphygmomanometry, the cardiac function using echocardiography, the expression level of target proteins by immunofluorescence staining, and the level of oxidative stress using dihydroethidium staining.
Results
Angiotensin II administration increased systolic blood pressure from about 130 to 180 mmHg, which was not affected by the empa treatment. The 4-week Ang II treatment did not significantly affect the systolic cardiac function (cardiac output, left ventricle ejection fraction) but impaired the diastolic function as indicated by a reduced E' and IVRT values, and an increased E/E' value. The Ang II treatment increased significantly the heart and right ventricle weight whereas the left ventricle + septum weight was slightly but not significantly increased. No such functional and structural changes were observed in the Ang II + empa treatment group. An increased immunofluorescence eNOS signal in the endothelium, and a higher level of ROS throughout the aorta wall were observed in the Ang II-treated group, both of which were significantly reduced in the empa + Ang II-treated group. In the Ang II-treated group, the high level of oxidative stress in the aorta was significantly reduced by the AT1 receptor antagonist losartan, the NADPH oxidase inhibitor VAS-2871, the eNOS inhibitor NG-nitro-L-arginine and also to a greater extent by the selective SGLT2 inhibitor empa compared to the dual SGLT1/2 inhibitor sotagliflozin.
Conclusion(s)
The present findings indicate that although the empa treatment did not affect the hypertensive response of rats to Ang II, the SGLT2 inhibitor prevented the deleterious impact of Ang II on the diastolic cardiac function and remodeling, and the upregulation of eNOS expression and oxidative stress in the aorta wall. Thus, these findings highlight the protective potential of empa on the cardiovascular system in a normoglycemic hypertensive experimental model.

Abstract
Abstract
Introduction
Several report showed the association between ambient air pollution including particular matter under 2.5um (PM2.5) and increasing rate of hospitalization for heart failure. However, these report analyzed mainly cross-sectional, epidemiological data, thus the reports regarding association between vulnerability to PM2.5 and specific populations in acute heart failure (AHF) were scarce.
Purpose
1. To analyze the association between air pollution and rate of hospitalization for AHF
2. To analyze whether the vulnerability to air pollution differ between specific populations in AHF. Methods
A case-cross over analysis was conducted to 4980 consecutive patients registered for multicenter acute heart failure registry in 2017 in our city Japan. This registry enrolled patients transferred to cardiovascular care unit (80 institutions) via emergency medical services across our city area. Logistic regression analysis were conducted to estimate percentage changes in the rate of acute heart failure hospitalization associated with per 1μg/m3 PM2.5 concentration increase. We also conducted subgroup analysis for patients stratified by age, gender, comorbidities, left ventricular ejection fraction, and clinical scenario.
Results
An increase in 1 μg/m3 PM2.5 concentration corresponded to 2.9% (95% CI 1.2–4.6%) increase in AHF hospitalization. Patients with age younger than 75, without prior heart failure hospitalization, without history of hypertension, without anemia, and with reduced ejection fraction were more susceptible to increase in PM2.5 concentration (Figure).
Conclusions
Increase in PM2.5 concentration was associated with increased rate of AHF hospitalization. Effect of PM2.5 may differ across specific AHF subpopulations.

Abstract
Abstract
Introduction
Paravalvular leakage (PVL) following transcatheter aortic valve replacement (TAVR) is associated with greater mortality. In clinical practice, determining PVL severity after TAVR remains challenging and often requires multiparametric assessment.
Purpose
This study sought to evaluate the respective value of various modalities of PVL assessments, including transthoracic echocardiography (TTE), cine-angiography, aortic regurgitation index (ARI), and closure time with adenosine diphosphate (CT-ADP), in the prediction of adverse clinical outcomes.
Methods
We included 1044 patients from our prospective TAVR registry between February 2010 and May 2019. Major adverse cardiac and cerebrovascular events (MACCE) was defined as a composite of all-cause death, myocardial infarction, stroke, and heart failure hospitalization within 1-year. Established cutoff values of ARI (<25) and CT-ADP (>180 sec) were used to assess the presence of PVL after TAVR.
Results
Moderate to severe PVL occurred in 14.2% and 5.2% of patients as measured by TTE and angiography. The rate of patients with ARI <25 and CT-ADP >180 sec were 36.5% and 24.9%, respectively. Among the four modalities, PVL evaluated by angiography predicted poorer clinical outcomes (Log rank test; p=0.001), whereas TTE, ARI <25, and CT-ADP >180 sec were not associated with 1-year MACCE. By multivariate Cox regression analysis, moderate to severe PVL by angiography was an independent predictor of 1-year MACCE (hazard ratio: 1.96; 95% confidence interval: 1.22–3.00; p=0.007).
Conclusions
Paravalvular leakage measured by angiography was evidenced as the most meaningful modality in the prediction of adverse clinical outcomes. Future multicenter studies are warranted to ensure these findings in the current TAVR era.

Abstract
Abstract
Introduction
Although there is an apparent rapid and spontaneous recovery of left ventricular ejection fraction (LVEF) in patients with takotsubo cardiomyopathy, recent studies have demonstrated the long-lasting functional impairment in those patients.
Purpose
We sought to evaluate the predictors of incomplete recovery in chronic phase and its impact on cardiovascular mortality after takotsubo cardiomyopathy.
Methods
Patients with takotsubo cardiomyopathy between 2008 and 2018 were retrospectively enrolled in three different institutions. Takotsubo cardiomyopathy was diagnosed according to the European Society of Cardiology Heart Failure Association criteria. After exclusion of in-hospital deaths, 407 patients were split into 2 subgroups according whether their LVEF were >50% (recovery group; n=333), or ≤50% (incomplete recovery group; n=74) at follow-up. The primary endpoint was the impact of incomplete recovery on cardiovascular mortality.
Results
Patients with incomplete recovery were more likely to be male, to have dementia, pacemaker, and supraventricular arrhythmia. C-reactive protein (CRP) levels on admission, at peak, and at discharge were significantly higher in patients with incomplete recovery. By multivariate logistic regression analysis, lower EF at discharge (odds ratio [OR]: 0.91; 95% confidence interval [CI]: 0.88 to 0.95; p<0.001) and higher CRP levels (OR: 5.56; 95% CI: 1.86 to 16.61; p<0.001) were independent predictors of incomplete recovery at follow-up. The cumulative event-free survival rate according to cardiovascular death was significantly lower in the incomplete recovery group (p<0.001; log-rank test).
Conclusions
We demonstrate that incomplete recovery after takotsubo cardiomyopathy is characterized by a residual systemic inflammation and an increased cardiac mortality at follow-up. Altogether, our findings underline patients with persistent inflammation as a high-risk subgroup, to target in future clinical trials with specific therapies to attenuate inflammation.

Abstract
In this study we investigated the relation between anterior disc displacement (ADD) and maxillomandibular morphology in skeletal anterior open bite with changes to the mandibular condyle. Thirty female patients (60 joints) with both conditions were evaluated. Magnetic resonance imaging of the temporomandibular joint (TMJ) was used to diagnose both ADD and changes to the mandibular condyle (erosion, osteophyte, and deformity). The relations among ADD, changes to the mandibular condyle, and maxillomandibular morphology were examined statistically. Changes to the mandibular condyle had a higher score than sym anterior open bite, the deviated side in asymmetric anterior open bite, and the non-deviated side. The score for disc displacement on the non-deviated side was lower than both the sym side and the deviated side. Unilateral changes to the mandibular condyle and unilateral disc displacement were not apparent in sym anterior open bite, but a unilateral non-displaced disc was seen only on the asymmetric side. Mandibular condylar changes were significantly more common on the deviated, than on the non-deviated, side. The SNB angle was significantly smaller, and the ANB, GZN, and SN-mandibular plane angles were significantly larger in sym anterior open bite. Overjet, ANB angle, GZN angle, and SN-MP angle were significantly larger, and the SNB angle was significantly smaller, in the presence of ADD without reduction and mandibular condylar deformity. We conclude that the prevalence of ADD without reduction and changes to the mandibular condyle were related to mandibular asymmetry and mandibular morphology in anterior open bite. This retrospective study suggests that ADD without reduction and mandibular condylar bone changes may be related to the progression of skeletal class II open bite and mandibular asymmetry in cases of skeletal open bite.

Abstract
Carbon-14 released from nuclear facilities has been assessed to contribute significantly to the radiation dose that people are exposed to through the food chain. However, the current dose coefficient for members of public, which is the ratio of the 50-year committed effective dose to ingested 1 Bq 14C, recommended by the International Commission on Radiological Protection (ICRP) is not based on experimental human metabolic data for 14C in nutrients and diet. Therefore, to validate the coefficient, we administered 13C-labelled nutrients consisting of four amino acids, three fatty acids, and one monosaccharide to volunteers as substitutes for 14C labelled nutrients and measured the 13C concentration in various excreta samples. Although metabolic models were constructed from the excretion data, a significant fraction of administered 13C was not recovered from some nutrients. The dose coefficients of 14C in uniformly labelled Japanese diet, which were estimated under several assumptions about the unrecoverable fraction, varied from (6.2 ± 0.9) × 10-11 to (8.9 ± 4.4) × 10-10 Sv Bq-1 and were approximately comparable to the current value of 5.8 × 10-10 Sv Bq-1 recommended by the ICRP. Further studies are necessary to elucidate the metabolism of 14C in various nutrients in the unrecoverable fraction.

Abstract
Electron antineutrino appearance is measured by the T2K experiment in an accelerator-produced antineutrino beam, using additional neutrino beam operation to constrain parameters of the Pontecorvo-Maki-Nakagawa-Sakata (PMNS) mixing matrix. T2K observes 15 candidate electron antineutrino events with a background expectation of 9.3 events. Including information from the kinematic distribution of observed events, the hypothesis of no electron antineutrino appearance is disfavored with a significance of 2.40σ and no discrepancy between data and PMNS predictions is found. A complementary analysis that introduces an additional free parameter which allows non-PMNS values of electron neutrino and antineutrino appearance also finds no discrepancy between data and PMNS predictions.

Abstract
Abstract
Background
Pulmonary artery aneurysm (PAA) occurs in some patients with pulmonary arterial hypertension (PAH) and can be accompanied by various complications.
Objective
The aim of the this study is to evaluate the characteristics of cardiac dysfunction and the prognostic impact of PAA by analysing the outcome of patients with PAH complicated by PAA.
Methods
We performed echocardiography and right-heart catheterization in 130 PAH patients. We measured the maximum dimensions of the main pulmonary artery (MPA) trunk. We evaluated the right ventricular (RV) function and the five-year prognosis of patients with PAA.
Results
The maximum MPA trunk diameter of >40 mm by echocardiography was defined as PAA. PAA appeared in 32 of the 130 PAH patients (24.6%: Group PAA), other 98 patients were defined as Group non-PAA. Systolic pulmonary artery pressure (76 ±18 vs. 61 ± 21 mmHg, P = 0.0008) and mean right atrial pressure (10.0 ± 8.1 vs. 5.4 ± 3.8 mmHg, P < 0.0001) were significantly higher in Group PAA than in Group non-PAA. RV end-diastolic area index was significantly larger (37.3 ± 8.8 vs. 32.3 ± 7.8 mmHg, P = 0.0048), and RV fractional area change (32 ± 8 vs. 36 ± 9 %, P = 0.0176) and RV longitudinal strain amplitude (-16 ±5 vs. -20 ± 6, P = 0.0017) were significantly lower in Group PAA than those in Group non-PAA. During the five-year follow-up period, 20 patients (15%) died. The five-year mortality rate was significantly higher in Group PAA compared to Group non-PAA (30% vs. 10%, P = 0.007).
Conclusion
In PAH patients with PAA, RV dysfunction was more severe and the prognosis was poor. Assessment of PAA can be a useful index for the extraction of high-risk PAH patients.

Abstract
Abstract
Background
The second generation drug-eluting stent (G2-DES) has been reported as superior to the first generation drug-eluting stent (G1-DES) in mid-term outcomes. However, the late-term outcomes between G1-DES and G2-DES in two-stenting for coronary bifurcation lesions are not well studied.
Purpose
To evaluate the late catch-up phenomenon and late-term target lesion revascularization (TLR) of two-stenting for coronary bifurcation lesions between G1-DES and G2-DES.
Methods
This study included 1133 lesions in 1089 patients undergoing drug eluting stent implantation with two stenting from 2004 to 2016. These consisted of 496 G1-DES implanted lesions and 637 G2-DES implanted lesions. Late-term follow-up angiography was performed without in-stent restenosis (ISR) and TLR at mid-term follow-up in 582 lesions (242 G1-DES lesions and 340 G2-DES lesions). ISR was defined as more than 50% restenosis. Late catch-up phenomenon was defined as ISR without ISR within 1 year following index stent implantation. Late-term TLR was defined as from 1 to 5 year TLR. Bifurcation lesions were defined as the main branch ranging from the proximal stem to the distal main branch with boundaries defined by 5 mm proximal and distal to the stent-implanted area, and the side branch ranging from the bifurcation carina to the distal side branch with boundaries defined by the carina and 5 mm distal to the stent-implanted area.
Results
The median follow-up duration was 5.1 years (the first and third quarters, 3.2 and 7.1 years). The late-catch up phenomenon rate significantly differed between the G1-DES and G2-DES groups (16.9% vs 8.4%, p=0.001). A significant difference in late catch-up between the same two groups was also observed in bifurcation lesions of the main branch (5.0% vs 0.6%, p=0.001) and side branch (10.3% vs 5.6%, p=0.033), respectively. The 5-year cumulative rates also differed between the two groups in TLR (8.2% vs 3.7% log-rank p=0.001), and late-term TLR (7.0% vs 3.6% log-rank p=0.001).
Conclusion
Two-stenting using G2-DES, compared with G1-DES, significantly reduced late-term restenosis and TLR. The restenosis rate in bifurcation area may be associated with differences between two groups in late-term outcome.

Abstract
Abstract
Background
Coupled abnormalities in arterial and left ventricular (LV) stiffness characterize aging and heart failure with preserved ejection fraction. We hypothesized that two measures of aortic stiffness, pulse wave velocity (PWV; reflecting segmental arterial wall stress in late systole) and total arterial compliance (TAC; reflecting distensibility of entire arterial system) differentially relate to cardiac structure and function in the elderly.
Methods
Among participants in the Atherosclerosis Risk In Community (ARIC) study, we assessed the cross-sectional relationship of carotid-femoral PWV (cfPWV) and TAC with echocardiographic measures of cardiac structure and function using multivariable linear regression adjusting for demographics and co-morbidities. TAC defined as stroke volume over pulse pressure [mL/mmHg]. Exclusions were LVEF <50%, prevalent HF, ≥moderate valvular disease.
Results
Of the 4,141 participants included in this study, mean age was 75±5 years, 41% were male, and 80% were white. Mean values were: cfPWV: 11.7±3.4 m/sec; TAC: 1.1±0.3 mL/mmHg. Greater cfPWV was associated with greater LV mass, worse systolic function, and worse diastolic function (Table). In contrast, worse TAC was not related to LV structure and did not demonstrate consistent relationships with measures of LV diastolic function, but was associated with worse LV longitudinal strain.
Echo measures cfPWV (1SD increase) TAC (1SD decrease) β Coefficient p-value β Coefficient p-value Cardiac structure Mean wall thickness, cm 0.10 <0.001 -0.01 0.499 LVMI, g/m2 0.04 0.016 0.02 0.299 LVEDVI, ml/m2 -0.07 <0.001 -0.02 0.332 LV systolic function LVEF (Simpson's), % -0.04 0.01 -0.16 <0.001 Longitudinal strain, % 0.14 <0.001 0.19 <0.001 LV diastolic function Septal e', cm/sec -0.08 <0.001 -0.02 0.169 E/e' septal 0.04 0.005 -0.02 0.138 LAVI, ml/m2 -0.05 0.003 -0.04 0.026
Conclusion
Two non-invasive measures of aortic stiffness, cfPWV and TAC, demonstrate differential associations with LV structure and function in late life. Greater cfPWV is more robustly associated with LV structure and function than TAC.

Abstract
Abstract
Background
Electrocardiographic (ECG) strain pattern has recently been associated with increased adverse outcome in aortic stenosis (AS) and after surgical aortic valve replacement (AVR). However, the relation linking ECG strain and cardiovascular MACE in patients with transcatheter aortic valve replacement (TAVR) has not been yet described.
Objectives
The aim of our study was to determine the impact and incremental value of ECG Strain pattern in predicting adverse outcome after TAVR.
Methods
585 patients with severe AS (mean age: 83±7 male 39.8%) were enrolled from November 2012 to May 2018. ECG strain pattern was defined as ≥1 mm concave down-sloping ST-segment depression and asymmetrical T-wave inversion in the lateral leads. Patients with baseline left bundle branch block (LBBB), right bundle branch block (RBBB) or ventricular paced rhythm were excluded. All patients underwent transthoracic echocardiography (TTE) before TAVR and at 30 days follow up. The primary endpoints of the study were the overall all-cause mortality after TAVR, rehospitalization for Hearth failure (HF), myocardial infarction and stroke.
Results
178 (30.4%) patients were excluded from analyses owing to the presence of either LBBB (n=103) or RBBB (n=75). Among the 407 remaining patients, 106 had ECG strain pattern (26.04%). Patients with ECG strain were significantly younger (81.6±8 years vs 83.5±6.8 years; p=0.022), had lower BMI (23±4.5 kg.m2 vs 27.9±6.8 kg.m2; p=0.02) more severe AS (mean gradient 52.3±15.2 mmHg vs 47.9±11.8 mmHg; p=0.003), significant lower LVEF (51.8±15% vs 58.4±10.7%; p<0.001). Left ventricular hypertrophy (LVH) was more frequent in patients with ECG Strain (indexed left ventricular mass (135.9±33.4 g.m2 vs 123.6±31.9 g.m2; p=0.002)). Death from any cause (22 (20.8%) vs 61 (20.3%); p=0.508) did not differ significantly between groups. Major adverse cardiovascular events (MACE) including death, stroke and heart failure at 1 month showed similar incidence (7 (6.6%) vs 17 (5.6%), p=0.439). Rehospitalization for hearth failure (HF) was significantly higher (33 (31.1%) vs 33 (11%); p<0.001) in patients with ECG strain pattern. In univariate model, ECG Strain was a strong predictor of rehospitalization for HF (HR 2.621 95% CI (1.607–4.277), p=0.001), independently of LVH assessed either by ECG criteria (HR 1.181 95% CI (0.698–1.997; p=0.536) or TTE (HR 1.557 95% (CI 0.701–3.458; p=0.277). ECG Strain remained associated with a higher risk of rehospitalization for hearth failure in multivariate analyses (HR 2.747 95% (CI 1.614- 4.674); p<0.001)
Conclusion
In patients with AS eligible for TAVR, ECG Strain Pattern is frequent and associated with an increased risk of post interventional heart failure regardless of preoperative LVH. ECG Strain pattern represents an easy, objective, reliable and low-cost tool to identify patients who may benefit from an extend and intensified post-interventional follow-up.

Abstract
Abstract
Background
Despite recommendations from clinical practice guidelines, there is scant evidence confirming the effects of vasodilators on clinical outcomes in patients with acute heart failure (AHF).
Purpose
We sought to investigate the effects of intravenous vasodilators on clinical outcomes and to identify the potential patient populations that would benefit from its use.
Methods
Data of 26 212 consecutive patients urgently hospitalized for AHF between 2009 and 2015 were extracted from a multicenter data registration system (Tokyo Cardiovascular Care Unit Network Database, including 72 institutions within the Tokyo metropolitan area in Japan). Patients who did not present with typical AHF episodes, including those without pulmonary congestion on physical and/or chest X-ray and serum B-type natriuretic peptide level <500 pg/ml, as well as those who had hypotension and/or hypoperfusion (systolic blood pressure [SBP] <100 mmHg) as dominant presentation, were excluded. Propensity scores were calculated with multiple imputation and 1:1 matching performed between patients with and without vasodilators. The primary endpoint was in-hospital mortality and the secondary endpoints were length of intensive/cardiovascular care unit (ICU/CCU) stay and hospital stay.
Results
Overall, 8 863 patients were included in the present analysis; they were predominantly male (57%) with a median age of 79 (interquartile range: 70–86) years. Compared with the group without vasodilator use, the vasodilator group had higher SBPs and heart rates and higher frequency of assisted ventilation use, but lower frequency of intravenous diuretics use. After propensity score matching, there were no significant differences in in-hospital mortality rates (7.8% vs. 8.9% in patients without vasodilators, p=0.16) or in length of ICU/CCU stay (5.8 days vs. 5.4 days, p=0.44) and hospital stay (22.7 days vs. 23.8 days, p=0.22) between the groups. However, in subgroup analyses, favorable impacts of vasodilator use on in-hospital mortality were observed among patients who had higher SBPs and among those who had no atrial fibrillation upon admission (Figure). In addition, vasodilators were likely to be more effective in AHF patients with SBP increasing; while levels below 140 mmHg of SBP appeared to be associated with an increased risk for mortality among patients treated with vasodilators compared with those without vasodilators.

Conclusions
In patients with AHF, vasodilator use was not universally associated with improved in-hospital outcomes; however, its effect was dependent of individual clinical presentation. Detailed phenotyping might aid tailoring of treatment strategies for patients with AHF.

Abstract
The gastrointestinal absorption of phenytoin (PHT), an antiepileptic drug, is often affected by its interaction with co-administered enteral nutrients through a nasogastric (NG) tube, resulting in decreased plasma PHT concentration. In this study, we measured the recovery rate (%) of PHT (Aleviatin® powder) passed through an NG tube when co-administered with distilled water or enteral nutrients (F2α®, Racol® NF, Ensure Liquid® and Renalen® LP). We also measured plasma PHT levels in rats, after oral co-administration of PHT with enteral nutrients. We demonstrate that PHT recovery rate was close to 100 % in all cases after passage through the NG tube. In the rat study, the AUC0→∞ of PHT concentration after oral administration significantly decreased when it was co-administered with F2α® and Racol® NF compared to distilled water. However, the AUC0→∞ of PHT was unchanged when co-administered with F2α® 2 h after initial PHT administration. We therefore conclude that the co-administration of PHT with F2α® and Racol® NF caused a reduction in the absorption of PHT from the gastrointestinal tract to the blood, without adsorption to the NG tube. The administration of enteral nutrients 2 h after PHT is one clear way to prevent a decrease in plasma PHT concentration.
