In-hospital initiation of angiotensin receptor-neprilysin inhibition in acute heart failure: the PREMIER trial.

BACKGROUND AND AIMS: The efficacy and safety of early sacubitril/valsartan (Sac/Val) initiation after acute heart failure (AHF) has not been demonstrated outside North America. The present study aimed to evaluate the effect of in-hospital Sac/Val therapy initiation after an AHF episode on N-terminal pro-B-type natriuretic peptide (NT-proBNP) level in Japanese patients. METHODS: This was an investigator-initiated, multicentre, prospective, randomized, open-label, blinded-endpoint pragmatic trial. After haemodynamic stabilization within 7 days after hospitalization, eligible inpatients were allocated to switch from angiotensin-converting enzyme inhibitor or angiotensin receptor blocker to Sac/Val (Sac/Val group) or to continue angiotensin-converting enzyme inhibitor or angiotensin receptor blocker (control group). The primary efficacy endpoint was the 8-week proportional change in geometric means of NT-proBNP levels. RESULTS: A total of 400 patients were equally randomized, and 376 (median age 75 years, 31.9% women, de novo heart failure rate 55.6%, and median left ventricular ejection fraction 37%) were analysed. The per cent changes in NT-proBNP level geometric means at Weeks 4/8 were -35%/-45% (Sac/Val group) and -18%/-32% (control group), and their group ratio (Sac/Val vs. control) was 0.80 (95% confidence interval 0.68-0.94; P = .008) at Week 4 and 0.81 (95% confidence interval 0.68-0.95; P = .012) at Week 8, respectively. In the pre-specified subgroup analyses, the effects of Sac/Val were confined to patients with a left ventricular ejection fraction < 40% and were more evident in those in sinus rhythm and taking mineralocorticoid receptor antagonists. No adverse safety signal was evident. CONCLUSIONS: In-hospital Sac/Val therapy initiation in addition to contemporary recommended therapy triggered a greater NT-proBNP level reduction in Japanese patients hospitalized for AHF. These findings may expand the evidence on Sac/Val therapy in this clinical situation outside North America.

Prevalence and Prognostic Implications of Changes in Tricuspid Regurgitation Severity in Acute Heart Failure.

BACKGROUND: Tricuspid regurgitation (TR), prevalent in acute heart failure (AHF), has a poor prognosis; however, the dynamics of TR severity during hospitalization and its prognostic implications remain unclear. We investigated TR dynamism during hospitalization and its prognostic impact in AHF. METHODS AND RESULTS: This is a post hoc analysis of a prospective multicenter study of patients with AHF who underwent echocardiographic TR severity evaluation at admission and before discharge. The primary end point was a combined of 1-year all-cause mortality and HF rehospitalization after discharge. Among 1079 participants, TR severity changed dynamically, with 60.3% of those with moderate TR and 29.6% of those with severe TR at admission being diagnosed as no or mild TR at discharge. In 3 groups stratified by changes in TR severity, the persistent TR groups had a higher incidence of the primary end point than the resolution and absence groups. In adjusted analyses, the persistent group (hazard ratio, 1.37; 95% confidence interval, 1.04-1.80), but not the resolution group (hazard ratio, 1.07; 95% confidence interval, 0.79-1.44), had a higher primary end point incidence than the absence group. CONCLUSIONS: TR severity at admission in patients with AHF can change dynamically and is associated with subsequent prognosis. Significant TR that remains even after decongestive therapy might be a target for further treatment in hospitalized patients with AHF.

Impact of the MitraClip G4 System on Routine Practice and Outcomes in Patients With Secondary Mitral Regurgitation.

BACKGROUND: The MitraClip G4 system is a new iteration of the transcatheter edge-to-edge repair system. We assessed the impact of the G4 system on routine practice and outcomes in secondary mitral regurgitation (2°MR).Methods and Results: Consecutive patients with 2°MR treated with either the MitraClip G2 (n=89) or G4 (n=63) system between 2018 and 2021 were included. Baseline characteristics, procedures, and outcomes were compared. Inverse probability of treatment weighting and Cox regression were used to adjust for baseline differences. Baseline characteristics were similar, except for a lower surgical risk in the G4 group (Society of Thoracic Surgeons Predicted Risk of Mortality ≥8: 38.1% vs. 56.2%; P=0.03). In the G4 group, more patients had short (≤2 mm) coaptation length (83.7% vs. 54.0%; P<0.001) and fewer clips were used (17.5% vs. 36.0%; P=0.02). Acceptable MR reduction was observed in nearly all patients, with no difference between the G4 and G2 groups (100% vs. 97.8%, respectively; P=0.51). The G4 group had fewer patients with high transmitral gradients (>5mmHg; 3.3% vs. 13.6%; P=0.03). At 1 year, there was no significant difference between groups in the composite endpoint (death or heart failure rehospitalization) after baseline adjustment (10.5% vs. 20.2%; hazard ratio 0.39; 95% confidence interval 0.11-1.32; P=0.13). CONCLUSIONS: The G4 system achieved comparable device outcomes to the early-generation G2, despite treating more challenging 2°MR with fewer clips.

Uptitration of Sacubitril/Valsartan and Outcomes in Patients With Heart Failure　- Insight From the REVIEW-HF Registry.

BACKGROUND: Guideline-directed medical therapy has become an important component of heart failure (HF) therapy, with sacubitril/valsartan as one of the recommended drugs; however, the real-world prognostic implications of sacubitril/valsartan uptitration are unclear. METHODS AND RESULTS: Patients with HF newly initiated on sacubitril/valsartan were registered in a retrospective multicenter study (REVIEW-HF). In all, 995 patients were divided into 3 groups according to the maximum dose achieved: high dose, sacubitril/valsartan 400 mg; intermediate dose, sacubitril/valsartan 200-<400 mg; and low dose, sacubitril/valsartan <200 mg. A total of 397 (39.9%) patients received high-dose sacubitril/valsartan; they had a significantly lower risk of mortality or HF hospitalization than patients in the low-dose (hazard ratio [HR] 0.39; 95% confidence interval [CI] 0.29-0.53; P<0.001) and intermediate-dose (HR 0.64; 95% CI 0.45-0.94; P=0.03) groups. In the multivariable Cox regression model, higher systolic blood pressure and maintained geriatric nutritional risk index were significantly associated with a higher incidence of achieving a high dose of sacubitril/valsartan. Patients who did not receive high-dose sacubitril/valsartan experienced more hypotension during the follow-up period, whereas hyperkalemia, severe renal events, and angioedema did not differ across the achieved dose classifications. CONCLUSIONS: Patients who achieved sacubitril/valsartan uptitration had a better prognosis than those who did not. Before sacubitril/valsartan uptitration, patients need to monitor blood pressure closely to prevent worsening events.

Imaging characteristics and clinical outcomes of hemodialysis vs. non-hemodialysis patients undergoing transcatheter aortic valve replacement: a Japanese single-center experience.

In 2021, Japan approved transcatheter aortic valve replacement (TAVR) for end-stage renal disease patients on hemodialysis (ESRD-HD). Yet, clinical/anatomical differences and outcomes between patients with and without ESRD-HD remain underexplored. This single-center study enrolled consecutive patients who underwent TAVR with the SAPIEN 3 between 2021 and 2023. Baseline characteristics and outcomes up to 1 year were compared. Inverse probability treatment weighting (IPTW) approach and Cox regression were used. Among 287 eligible patients, 59 had ESRD-HD. Patients with ESRD-HD were predominantly male (59.2% vs. 40.7%; p = 0.01), younger (78.0 [73.5-83.5] vs. 84.0 [79.8-88.0]; < 0.001), with lower body mass index (21.4 [19.6-23.3] vs. 22.9 [20.3-25.3]; p = 0.02], higher surgical risk (Society of Thoracic Surgeons Predicted Risk of Mortality ≧8%: 28 [47.5%] vs. 34 [14.9%]; p < 0.001), and more peripheral artery disease (25.4% vs. 4.8%; p < 0.001). Patients with ESRD-HD had a significantly higher prevalence of severely calcified femoral arteries (12.5% vs. 2.6%; p < 0.001). However, there were no differences in the computed-tomographic (CT) anatomical characteristics of the aortic valve complex (AVC), including the aortic valve calcium score (1995 [1372-3374] vs. 2195 [1380-3172]; p = 0.65) or the presence of moderate or severe left ventricular outflow tract calcification (4.3% vs. 5.2%; p > 0.99). Major vascular complications were rare, and technical (98.3% vs. 98.7%; p > 0.99) and device success (75.9% vs. 82.4%; p = 0.26) rates were high in both. At 1 year, there were no significant differences in a composite endpoint of death, stroke, major bleeding, or myocardial infarction (32.4% vs. 33.2%; HR 1.12; 95% CI 0.45-2.80; p = 0.81), nor its components after baseline adjustment.

Rationale and design of an investigator-initiated, multicenter, prospective, placebo-controlled, double-blind, randomized trial to evaluate the effects of finerenone on vascular stiffness and cardiorenal biomarkers in type 2 diabetes and chronic kidney disease (FIVE-STAR).

BACKGROUND: The overactivation of mineralocorticoid receptor (MR) plays a key pathological role in the progression of cardiovascular and renal diseases by promoting pro-inflammatory and pro-fibrotic signaling. Recently, it has been found that finerenone, a novel nonsteroidal selective MR antagonist, can robustly improve cardiorenal outcomes in patients with type 2 diabetes (T2D) and a wide spectrum of chronic kidney disease (CKD). However, the mechanisms underlying the cardiorenal benefits of finerenone are poorly understood. Further, whether the clinical benefits are mediated by an improvement in vascular stiffness is not confirmed. Therefore, the current study aims to evaluate the effects of finerenone on vascular stiffness as assessed using cardio ankle vascular index (CAVI) and relevant cardiorenal biomarkers in patients with T2D and CKD. METHODS: The Effects of Finerenone on Vascular Stiffness and Cardiorenal Biomarkers in Type 2 Diabetes and Chronic Kidney Disease (FIVE-STAR) is an ongoing, investigator-initiated, multicenter, prospective, placebo-controlled, double-blind, randomized clinical trial in Japan. Its target sample size is 100 subjects. Recruitment will be performed from September 2023 to July 2024. After obtaining informed consent, eligible participants with T2D and CKD (25 mL/min/1.73 m2 ≤ estimated glomerular filtration ratio [eGFR] < 90 mL/min/1.73 m2 and 30 mg/g Cr ≤ urinary albumin-to-creatinine ratio [UACR] < 3500 mg/g Cr) will be equally randomized to receive 24-week treatment with either finerenone (starting dose at 10 mg once daily in participants with a baseline eGFR < 60 mL/min/1.73 m2 or at 20 mg once daily in those with a baseline eGFR ≥ 60 mL/min/1.73 m2) or dose-matched placebo. The primary endpoint is the change from baseline in CAVI at 24 weeks. The secondary endpoints are changes from baseline in UACR at 12 and 24 weeks and relevant serum and urinary biomarkers at 24 weeks. As an exploratory endpoint, proteomic analysis using the Olink® Target 96 panels will be also performed. DISCUSSION: FIVE-STAR is the first trial evaluating the therapeutic impact of finerenone on vascular stiffness and relevant cardiorenal biomarkers in patients with T2D and CKD. This study will provide mechanistic insights on the clinical benefits of finerenone based on recent cardiovascular and renal outcome trials.

Newer versus Early Generation of the MitraClip for Primary Mitral Regurgitation: A Japanese Single-Center Experience.

Background: The MitraClip G4 system is the latest version of the transcatheter edge-to-edge repair (TEER) system for mitral regurgitation (MR). We aimed to investigate the impact of the new system on routine clinical practice and patient outcomes in the treatment of primary MR. Methods: Consecutive patients with primary MR who underwent TEER with either the MitraClip G2 or G4 between 2018 and 2021 were enrolled from a single center registry. Baseline clinical and echocardiographic characteristics as well as procedural and clinical outcomes up to 1 year were compared between groups. Technical and device success were defined in accordance with the Mitral Valve Academic Research Consortium criteria. Results: Among 71 patients with primary MR, 34 were treated with G2 and 37 were treated with G4. Patients treated with G4 had lower surgical risk (7.74 [5.04, 14.97] vs. 5.26 [3.98, 6.40]; p < 0.01) than those with G2. There were no significant differences in other baseline clinical variables between groups. On baseline echocardiography, MR volume and flail gap were significantly greater in the G4 group than in the G2 group (regurgitant volume: 63 [41-76] mL vs. 68 [62-84] mL; p = 0.04, flail gap: 4.5 [3.5-5.5] mm vs. 5.4 [4.5-7.1] mm; p = 0.04). Technical success was achieved in over 95% of both groups with no significant difference (p > 0.99). Device success was achieved in 61.8% of the G2 group, while in 70.3% of the G4 group (p = 0.47). Post-procedural MR severity was comparable (p = 0.42) and there was no significant difference in the occurrence of mitral stenosis (p = 0.61) between groups. Among patients who reached 1-year follow-up (n = 54), there was no significant difference between groups in a composite endpoint of death or heart failure rehospitalization (10.5% vs. 20.2%; HR 0.61; 95% CI 0.17-2.22; p = 0.45). Residual heart failure symptoms (NYHA ≥ 3) at 1 year were observed in 3.7% of the G2 group, while no patient in the G4 group (p > 0.99). Conclusions: The MitraClip G4 system achieved comparable device outcomes to the early-generation device (G2), despite treating more severe primary MR with a larger flail gap.

Risk stratification of patients with cardiac sarcoidosis: the ILLUMINATE-CS registry.

AIMS: This study evaluated the prognosis and prognostic factors of patients with cardiac sarcoidosis (CS), an underdiagnosed disease. METHODS AND RESULTS: Patients from a retrospective multicentre registry, diagnosed with CS between 2001 and 2017 based on the 2016 Japanese Circulation Society or 2014 Heart Rhythm Society criteria, were included. The primary endpoint was a composite of all-cause death, hospitalization for heart failure, and documented fatal ventricular arrhythmia events (FVAE), each constituting exploratory endpoints. Among 512 registered patients, 148 combined events (56 heart failure hospitalizations, 99 documented FVAE, and 49 all-cause deaths) were observed during a median follow-up of 1042 (interquartile range: 518-1917) days. The 10-year estimated event rates for the primary endpoint, all-cause death, heart failure hospitalizations, and FVAE were 48.1, 18.0, 21.1, and 31.9%, respectively. On multivariable Cox regression, a history of ventricular tachycardia (VT) or fibrillation [hazard ratio (HR) 2.53, 95% confidence interval (CI) 1.59-4.00, P < 0.001], log-transformed brain natriuretic peptide (BNP) levels (HR 1.28, 95% CI 1.07-1.53, P = 0.008), left ventricular ejection fraction (LVEF) (HR 0.94 per 5% increase, 95% CI 0.88-1.00, P = 0.046), and post-diagnosis radiofrequency ablation for VT (HR 2.65, 95% CI 1.02-6.86, P = 0.045) independently predicted the primary endpoint. CONCLUSION: Although mortality is relatively low in CS, adverse events are common, mainly due to FVAE. Patients with low LVEF, with high BNP levels, with VT/fibrillation history, and requiring ablation to treat VT are at high risk.

Prenatal glucocorticoid administration accelerates the maturation of fetal rat hepatocytes.

BACKGROUND: Prenatal glucocorticoid (GC) is clinically administered to pregnant women who are at risk of preterm birth for the maturation of cardiopulmonary function. Preterm and low-birth-weight infants often experience liver dysfunction after birth because their livers are immature. However, the effects of prenatal GC administration on the liver remain unclear. We aimed to investigate the effects of prenatal GC administration on the maturation of liver hepatocytes in preterm rats. METHODS AND RESULTS: Dexamethasone (DEX) was administered to pregnant Wistar rats on gestational days 17 and 19 before cesarean section. Real-time reverse transcription-polymerase chain reaction (RT-PCR) was performed to determine the mRNA levels of albumin, hepatocyte nuclear factor-4 alpha (HNF4α), hepatocyte growth factor (HGF), thymus cell antigen 1 (Thy-1), cyclin B, and Cyclin-dependent kinase 1 (CDK1) in the liver samples. Immunohistochemical staining and enzyme-linked immunosorbent assay were performed to examine protein production. The hepatocytes enlarged because of growth and prenatal DEX administration. Albumin, HNF4α, and HGF levels increased secondary to growth and prenatal DEX administration. The levels of the cell cycle markers cyclin B and CDK1 gradually decreased during growth and with DEX administration. CONCLUSIONS: The results suggest that prenatal GC administration leads to hepatocyte maturation via expression of HNF4α and HGF in preterm fetuses.

Prenatal glucocorticoid administration enhances bilirubin metabolic capacity and increases Ugt1a and Abcc2 gene expression via glucocorticoid receptor and PXR in rat fetal liver.

AIM: Jaundice is especially common in premature infant born before 35 weeks. Because the premature infant liver is not fully developed at birth it may be incomplete the bilirubin metabolism. The purpose was to evaluate the metabolism and the excretion of bilirubin in the premature infant rat liver following prenatal glucocorticoid (GC) administration. METHODS: Dexamethasone (DEX) was administered subcutaneously to pregnant Wistar rats for two consecutive days on gestational days 17 and 19. The fetus were delivered by cesarean section in gestational days 19 and 21. The mRNA levels and protein levels of bilirubin-metabolic enzymes and transporters in the fetal liver tissues were analyzed using RT-PCR immunohistochemistry staining and ELISA, respectively. We evaluated that the effect of bilirubin-metabolic enzymes in the primary fetal rat hepatocytes treated with DEX after pretreated with glucocorticoid receptor (GR, Nr3c1) and Pxr (Nr1i2) siRNA. RESULTS: Ugt1a1 and Bsep (Abcb11) mRNA levels were significantly increased in the fetuses by prenatal GC administration. The mRNA levels of nuclear transcription factors Nr1i2, Car (Nr1i3), and Rxrα (Nr2b1) were also significantly increased in the fetuses by prenatal GC administration. In addition, DEX increased Nr1i2, Ugt1a1, and Abcc2 (Mrp2) mRNA levels in the primary fetal hepatocytes. The Nr3c1 or Nr1i2 siRNA-mediated knockdown suppressed the increases of Ugt1a1, and Abcc2 mRNA levels induced by DEX, indicating that DEX are mediated by GC receptor and PXR in primary fetal hepatocytes. CONCLUSIONS: These results suggest that prenatal GC administration increases bilirubin-metabolic ability, in the premature liver, which may prevent jaundice in neonates.

Antenatal Glucocorticoid Administration Promotes Cardiac Structure and Energy Metabolism Maturation in Preterm Fetuses.

Although the rate of preterm birth has increased in recent decades, a number of preterm infants have escaped death due to improvements in perinatal and neonatal care. Antenatal glucocorticoid (GC) therapy has significantly contributed to progression in lung maturation; however, its potential effects on other organs remain controversial. Furthermore, the effects of antenatal GC therapy on the fetal heart show both pros and cons. Translational research in animal models indicates that constant fetal exposure to antenatal GC administration is sufficient for lung maturation. We have established a premature fetal rat model to investigate immature cardiopulmonary functions in the lungs and heart, including the effects of antenatal GC administration. In this review, we explain the mechanisms of antenatal GC actions on the heart in the fetus compared to those in the neonate. Antenatal GCs may contribute to premature heart maturation by accelerating cardiomyocyte proliferation, angiogenesis, energy production, and sarcoplasmic reticulum function. Additionally, this review specifically focuses on fetal heart growth with antenatal GC administration in experimental animal models. Moreover, knowledge regarding antenatal GC administration in experimental animal models can be coupled with that from developmental biology, with the potential for the generation of functional cells and tissues that could be used for regenerative medical purposes in the future.

Effects of canagliflozin on NT-proBNP stratified by left ventricular diastolic function in patients with type 2 diabetes and chronic heart failure: a sub analysis of the CANDLE trial.

BACKGROUND: Identification of the effective subtypes of treatment for heart failure (HF) is an essential topic for optimizing treatment of the disorder. We hypothesized that the beneficial effect of SGLT2 inhibitors (SGLT2i) on the levels of N-terminal pro-brain natriuretic peptide (NT-proBNP) might depend on baseline diastolic function. To elucidate the effects of SGLT2i in type 2 diabetes mellitus (T2DM) and chronic HF we investigated, as a post-hoc sub-study of the CANDLE trial, the effects of canagliflozin on NT-proBNP levels from baseline to 24 weeks, with the data stratified by left ventricular (LV) diastolic function at baseline. METHODS: Patients (n = 233) in the CANDLE trial were assigned randomly to either an add-on canagliflozin (n = 113) or glimepiride treatment groups (n = 120). The primary endpoint was a comparison between the two groups of the changes from baseline to 24 weeks in NT-pro BNP levels, stratified according to baseline ventricular diastolic function. RESULTS: The change in the geometric mean of NT-proBNP level from baseline to 24 weeks was 0.98 (95% CI 0.89-1.08) in the canagliflozin group and 1.07 (95% CI 0.97-1.18) in the glimepiride group. The ratio of change with canagliflozin/glimepiride was 0.93 (95% CI 0.82-1.05). Responder analyses were used to investigate the response of an improvement in NT-proBNP levels. Although the subgroup analyses for septal annular velocity (SEP-e') showed no marked heterogeneity in treatment effect, the subgroup with an SEP-e' < 4.7 cm/s indicated there was an association with lower NT-proBNP levels in the canagliflozin group compared with that in the glimepiride group (ratio of change with canagliflozin/glimepiride (0.83, 95% CI 0.66-1.04). CONCLUSIONS: In the subgroup with a lower LV diastolic function, canagliflozin showed a trend of reduced NT-pro BNP levels compared to that observed with glimepiride. This study suggests that the beneficial effects of canagliflozin treatment may be different in subgroups classified by the severity of LV diastolic dysfunction.

Identification of interleukin-16 production on tumor aggravation in hepatocellular carcinoma by a proteomics approach.

BACKGROUND: Cytokines play an important role in the immune response, angiogenesis, cell growth, and differentiation in hepatocellular carcinoma (HCC). OBJECTIVE: We performed a comprehensive study to identify tumor-related cytokines and pathways involved in HCC pathogenesis. METHODS: Cytokine production was evaluated in human HCC tissues and adjacent non-tumor tissues using an antibody-based protein array technique. We compared cytokine expression in HCC tissues with that of hepatic hemangioma (HH), liver metastasis of colorectal cancer, and noncancerous liver tissues from transplantation donors. The protein levels and localization of the candidate cytokines were analyzed by western blotting and immunohistochemistry. RESULTS: Increased expression of interleukin (IL)-1 receptor antagonist, macrophage migration inhibitory factor, and IL-16 was observed in HCC and paired adjacent non-tumor tissues compared with noncancerous livers. In addition, there were increased IL-16 levels in HCC tissues compared with HH. IL-16 treatment significantly increased cell proliferation in vitro. The expression of extracellular signal-regulated kinase (ERK)1/2 and cyclin D1 was markedly increased in cells from two HCC cell lines, Huh7 and HepG2, in a dose- and time-dependent manner. Phosphorylated to total ERK1/2 ratio was increased in Huh7 cells following IL-16 50 ng/ml, but not HepG2 cells. ERK phosphorylation have occurred earlier than protein accumulation at 48 h. Pretreatment with the ERK inhibitor, FR18024, or an anti-IL-16 antibody reduced the increase in IL-16 production in HCC cells. CONCLUSIONS: These results suggest that cell proliferation induced by IL-16 is mediated through the ERK pathway, thus, we identified a new factor associated with HCC tumor growth.

Prognostic Implications of Reductions in Heart Rates in Patients With Acute Heart Failure and Atrial Fibrillation.

BACKGROUND: Atrial fibrillation (AF) is a common arrhythmia in patients with acute heart failure (AHF). Heart rate (HR) also changes significantly over time. However, the association between changes in HR in AF patients and prognosis is uncertain.Methods and Results:We investigated the association between HR reduction in AF achieved within 48 h of admission and 60-day mortality in patients with AHF from the REALITY-AHF study. The percentage HR (%HR) reduction was calculated as (baseline HR-HR at 48 h) / baseline HR × 100. The primary endpoint was 60-day all-cause mortality. In 468 patients with confirmed AF at both admission and 48 h after admission, the median HR at these time points was 105±31 and 84±18 beats/min, respectively. The median %HR reduction was 15.4% (interquartile range 2.2-31.4%). During the 60 days of admission, 39 deaths (8.3%) were recorded, and the %HR reduction within 48 h was significantly associated with 60-day mortality in the unadjusted model (hazard ratio [HR] 0.85; 95% confidence interval [CI] 0.77-0.95; P=0.005) and after adjusting for other covariates (HR 0.81; 95% CI 0.68-0.96; P=0.016).Furthermore, the %HR reduction was associated with a significant reduction in 60-day mortality in patients with higher baseline HR. CONCLUSIONS: %HR reduction is associated with a better short-term prognosis in patients with AHF presenting with AF, particularly in those with a rapid ventricular response.

Impact of perioperative change in physical function on midterm outcomes after transcatheter aortic valve implantation.

Preoperative frailty diminishes the potential for functional recovery after transcatheter aortic valve implantation (TAVI). However, perioperative changes in physical status and their impact on prognosis after TAVI have not previously been reported. Therefore, this study aimed to investigate whether perioperative changes in physical function affect prognosis in patients undergoing TAVI. We retrospectively reviewed 257 patients who underwent TAVI. The Short Physical Performance Battery (SPPB), an objective physical status assessment tool, was evaluated pre- and post-TAVI. Patients were divided into two groups: (i) patients whose SPPB score declined in the perioperative period (the decline group) and (ii) patients whose SPPB score did not decline in the perioperative period (the non-decline group). The primary endpoint was unplanned hospitalization owing to heart failure or cardiovascular death following TAVI. The mean follow-up period was 385 ± 151 days, mean age was 83.2 ± 5.8 years, and 67% of the patients were women. Sixteen patients required readmission owing to heart failure, and seven experienced cardiovascular-related death. Kaplan-Meier analysis revealed that the event-free rate was significantly lower in the decline group (log-rank, p = 0.006). A stepwise multivariate logistic regression analysis showed that a perioperative change in SPPB was significantly associated with primary endpoints (odds ratio, 1.51; 95% confidence interval, 1.12-2.04). Perioperative change in physical function was an independent risk factor for heart failure, hospitalization, or cardiovascular death following TAVI.

Coronavirus Disease 2019 (COVID-19) Information for Cardiologists　- Systematic Literature Review and Additional Analysis.

BACKGROUND: Despite the rapidly increasing attention being given to Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection, more commonly known as coronavirus disease 2019 (COVID-19), the relationship between cardiovascular disease and COVID-19 has not been fully described.Methods and Results:A systematic review was undertaken to summarize the important aspects of COVID-19 for cardiologists. Protection both for patients and healthcare providers, indication for treatments, collaboration with other departments and hospitals, and regular update of information are essentials to front COVID-19 patients. CONCLUSIONS: Because the chief manifestations of COVID-19 infection are respiratory and acute respiratory distress syndrome, cardiologists do not see infected patients directly. Cardiologists need to be better prepared regarding standard disinfection procedures, and be aware of the indications for extracorporeal membrane oxygenation and its use in the critical care setting.

Clinical and Prognostic Values of ALBI Score in Patients With Acute Heart Failure.

BACKGROUND: Although liver dysfunction is one of the common complications in patients with acute heart failure (AHF), no integrated marker has been defined. The albumin-bilirubin (ALBI) score has recently been proposed as a novel, clinically-applicable scoring system for liver dysfunction. We investigated the utility of the ALBI score in patients with AHF compared to that for a preexisting liver dysfunction score, the Model of End-Stage Liver Disease Excluding prothrombin time (MELD XI) score. METHODS: We evaluated ALBI and MELD XI scores in 1,190 AHF patients enrolled in the prospective, multicentre Registry Focused on Very Early Presentation and Treatment in Emergency Department of Acute Heart Failure study. The associations between the two scores and the clinical profile and prognostic predictive ability for 1-year mortality were evaluated. RESULTS: The mean MELD XI and ALBI scores were 13.4±4.8 and -2.25±0.48, respectively. A higher ALBI score, but not higher MELD XI score, was associated with findings of fluid overload. After adjusting for pre-existing prognostic factors, the ALBI score (HR 2.11, 95% CI: 1.60-2.79, p<0.001), but not the MELD XI score (HR 1.02, 95% CI: 0.99-1.06, p=0.242), was associated with 1-year mortality. Likewise, area under the receiver-operator-characteristic curves for 1-year mortality significantly increased when the ALBI score (0.71 vs. 0.74, p=0.020), but not the MELD XI score (0.71 vs. 0.72, p=0.448), was added to the pre-existing risk factors. CONCLUSIONS: The ALBI score is potentially a suitable liver dysfunction marker that incorporates information on fluid overload and prognosis in patients with AHF. These results provide new insights into heart-liver interactions in AHF patients.

Palliative Care in Patients with Advanced Heart Failure.

The heart failure (HF) guidelines recommend palliative care; however, it can often be difficult to determine the timing of palliative care referral. Because HF with fluid retention and low-cardiac output may trigger several unpleasant symptoms, continuous HF treatment is required to alleviate these symptoms in advanced HF. The patients with HF often suffer from total pain; therefore, the support from a multidisciplinary team plays a crucial role to improve quality of life of the patients and their families not only in the terminal phase but also from the early stage.

Very Early Diuretic Response After Admission for Acute Heart Failure.

BACKGROUND: In hospitalized heart failure patients, a poor diuretic response (DR) during the first days of hospital admission is associated with worse outcomes. However, it remains unknown whether DR in the first hours has similar prognostic value. Moreover, data on the sequential change in DR during hospital admission are lacking. METHODS AND RESULTS: DR (urine output per 40-mg furosemide-equivalent diuretics dose) was measured from 0 to 6 hours (DR6), 6 to 48 hours (DR6-48), and 0 to 48 hours (DR48) of the patient's emergency department (ED) arrival in 1551 patients with acute heart failure (AHF; mean age 78 years, 56% male, and 48% de novo patients with heart failure). Patients with a poor DR within the first 6 hours were older age, had worse renal function, and were already on diuretic treatment before admission. DR6 was only weakly correlated with DR6-48 (Spearman's rho = 0.273; P < .001). DR6, DR6-48, and DR48 were all significantly associated with 60-day mortality independent of other prognostic factors. DR6 and DR48 showed comparable prognostic ability. However, the model combining DR6 with DR6-48 significantly exceeded both DR6 (net reclassification improvement 0.249; P = .032) and DR48 (net reclassification improvement 0.287; P = 0.025) with regard to 60-day mortality prediction. CONCLUSIONS: DR measured within the first 6 hours of ED arrival and DR measured during the first 48 hours in patients with AHF have similar prognostic value, although they were moderately correlated. Changes in DR over time provide additional prognostic information.
