Prognostic impact of MitraScore in elderly Asian patients with heart failure: sub-analysis of FRAGILE-HF.

Aims: MitraScore is a novel, simple, and manually calculatable risk score developed as a prognostic model for patients undergoing transcatheter edge-to-edge repair (TEER) for mitral regurgitation. As its components are considered prognostic in heart failure (HF), we aimed to investigate the usefulness of the MitraScore in HF patients.

Methods And Results: We calculated MitraScore for 1100 elderly patients (>65 years old) hospitalized for HF in the prospective multicentre FRAGILE-HF study and compared its prognostic ability with other simple risk scores.

agliflozin for the attenuation of albuminuria in atients with hat failure and type 2 diabetes (DAPPER study): a multicentre, randomised, open-label, parallel-group, standard treatment-controlled trial.

Background: Sodium-glucose cotransporter 2 (SGLT2) inhibitors reduce the urinary albumin-to-creatinine ratio (UACR) in patients with elevated levels of albuminuria in the presence or absence of heart failure (HF) or type 2 diabetes mellitus (T2D). However, these effects have not yet been reported in the presence of both HF and T2D. This lack of evidence prompted us to conduct a clinical trial on the effects of dapagliflozin on UACR in patients with HF and T2D.

Association and Prognostic Value of Multidomain Frailty Defined by Cumulative Deficit and Phenotype Models in Patients With Heart Failure.

Background: Frailty is associated with a poor prognosis in older patients with heart failure (HF). However, multidomain frailty assessment tools have not been established in patients with HF, and the association between the frailty phenotype and the deficit-accumulation frailty index in these patients is unclear. We aimed to understand this relationship and evaluate the prognostic value of the deficit-accumulation frailty index in older patients with HF.

Dynamic changes in echocardiographic parameters in acute decompensated heart failure: REALITY-ECHO.

Background: Appropriate evaluation of hemodynamic status is vital in the management of acute heart failure (AHF). We aimed to investigate the changes in echocardiographic parameters during very acute phases of AHF and their association with clinical outcomes.

Methods: Patients who were admitted to four Japanese hospitals with AHF were prospectively enrolled.

Establishment of a reference interval for glycated albumin based on medical check-up data from multiple medical institutions.

Data were collected to establish a reference interval for glycated albumin (GA), as well as to calculate a cutoff value for diagnosing diabetes mellitus and the GA level corresponding to a 75-g oral glucose tolerance test (OGTT) 2 h plasma glucose (2h-PG) level of 200 mg/dL. This study involved 1,843 subjects who were undergoing medical check-ups at several medical institutions and whose HbA1c and GA levels had been measured by OGTT. The GA reference interval that was calculated based on the data obtained from study subjects with normal glucose tolerance was 12.

Prognostic impact of cachexia by multi-assessment in older adults with heart failure: FRAGILE-HF cohort study.

Background: Cachexia substantially impacts the prognosis of patients with heart failure (HF); however, there is no standard method for cachexia diagnosis. This study aimed to investigate the association of Evans's criteria, consisting of multiple assessments, with the prognosis of HF in older adults.

Methods: This study is a secondary analysis of the data from the FRAGILE-HF study, a prospective multicentre cohort study that enrolled consecutive hospitalized patients aged ≥65 years with HF.

Expanding the Spectrum of TEER Suitability: Evidence From the EXPAND G4 Post Approval Study.

Background: Anatomical and clinical criteria to define mitral transcatheter edge-to-edge repair (TEER) "unsuitability" have been proposed on the basis of a Heart Valve Collaboratory consensus opinion from physician experience with early-generation TEER devices but lacked an evidence-based approach.

Objectives: The aim of this study was to explore the spectrum of TEER suitability using echocardiographic and clinical outcomes from the EXPAND G4 real-world postapproval study.

Methods: EXPAND G4 is a global, prospective, multicenter, single-arm study that enrolled 1,164 subjects with mitral regurgitation (MR) treated with the MitraClip G4 System.

Preceding Aortic Bare Stenting for Visceral and Limb Malperfusion before Proximal Surgical Repair of Stanford Type A Aortic Dissection.

Mesenteric malperfusion is a fatal complication of acute aortic dissection, which should rapidly be repaired. However, the optimal treatment strategy remains controversial in patients with type A aortic dissection. We report on a case with aortic bare stenting for visceral and lower limb malperfusion prior to the proximal repair.

Midterm outcomes after surgical aortic valve replacement with the INSPIRIS RESILIA from a multicenter AVR registry.

Background: There have been few reports on the mid- to long-term safety and efficacy validation of the INSPIRIS RESILIA aortic bioprosthesis (Edwards Lifesciences LLC, Irvine, CA, USA) in Japan. Herein, we report the mid-term results of surgical aortic valve replacement (AVR) for aortic stenosis using INSPIRIS and evaluate the hemodynamics compared to the CEP Magna series from the multicenter AVR registry (the ACTIVIST registry).

Methods: Of the 1967 patients who underwent surgical or transcatheter AVR from the ACTIVIST registry, 66 patients who underwent isolated surgical AVR with INSPIRIS by December 2020 were included in this study, and the early and mid-term results were evaluated.

Association of Left Atrial Size With Stroke or Systemic Embolism in Patients With Atrial Fibrillation Having Undergone Bioprosthetic Valve Replacement From the BPV-AF Registry.

The left atrial volume index (LAVI) is important for predicting thromboembolism in patients with non-valvular atrial fibrillation (AF), but the utility of LAVI for predicting thromboembolism in patients with both bioprosthetic valve replacement and AF remains unclear. Of 894 patients from a previous multicenter prospective observational registry (BPV-AF Registry), 533 whose LAVI data had been obtained by transthoracic echocardiography were included in this subanalysis. Patients were divided into tertiles (T1-T3) according to LAVI as follows: T1 (n=177), LAVI=21.

Derivation and validation of a machine learning-based risk prediction model in patients with acute heart failure.

Background: Risk stratification is important in patients with acute heart failure (AHF), and a simple risk score that accurately predicts mortality is needed. The aim of this study is to develop a user-friendly risk-prediction model using a machine-learning method.

Methods: A machine-learning-based risk model using least absolute shrinkage and selection operator (LASSO) regression was developed by identifying predictors of in-hospital mortality in the derivation cohort (REALITY-AHF), and its performance was externally validated in the validation cohort (NARA-HF) and compared with two pre-existing risk models: the Get With The Guidelines risk score incorporating brain natriuretic peptide and hypochloremia (GWTG-BNP-Cl-RS) and the acute decompensated heart failure national registry risk (ADHERE).

The interaction between physical frailty and prognostic impact of heart failure medication in elderly patients.

Aims: Frailty is highly prevalent and associated with poor prognoses in elderly patients with heart failure (HF). However, the potential effects of physical frailty on the benefits of HF medications in elderly patients with HF are unclear. We aimed to determine the influence of physical frailty on the prognosis of HF medications in elderly patients with HF with reduced and mildly reduced ejection fraction (HFr/mrEF).

1-year outcomes of patients implanted with the Perceval sutureless valve: the Japanese post-marketing surveillance study.

Sutureless offers an alternative to standard valves in surgical aortic valve replacement (SAVR). We sought to confirm the efficacy and safety of the Perceval sutureless valve in Japanese patients. Prospective observational study of 204 patients who underwent SAVR with Perceval at 19 sites in Japan between March and December 2019.

Background: Hypochloremia is a risk factor for poor outcomes in patients with acute heart failure (AHF). However, the changes in serum chloride levels during decongestion therapy and their impact on prognosis remain unknown.

Methods: In total, 2798 patients with AHF were retrospectively studied and divided into four groups according to their admission and discharge serum chloride levels: (1) normochloremia (n=2,192, 78%); (2) treatment-associated hypochloremia, defined as admission normochloremia with a subsequent decrease (<98 mEq/L) during hospitalization (n=335, 12%); (3) resolved hypochloremia, defined as admission hypochloremia that disappeared at discharge (n=128, 5%); (4) persistent hypochloremia, defined as chloride <98 mEq/L at admission and discharge (n = 143, 5%).

Impact of radial compression protocols on radial artery occlusion and hemostasis time in coronary angiography.

Protocols for hemostasis after trans-radial approach (TRA) vary depending on the institute as there is no established evidence-based protocol. This study aimed to investigate the clinical implications of radial compression protocols. Consecutive patients who underwent outpatient invasive catheter angiography before and after April 2018 were treated with traditional and new protocols, respectively.

Geographic Variations on the Safety and Efficacy of the Supreme Biodegradable Polymer DES: Results From PIONEER III.

Background: The PIONEER III trial showed the 12-month safety and efficacy of the Supreme drug-eluting stent (DES) vs the durable polymer everolimus-eluting stent. We sought to assess whether the characteristics and clinical outcomes of the Supreme DES in PIONEER III were consistent among patients by enrollment location.

Methods: This subgroup analysis of the PIONEER III trial compared the characteristics and outcomes of patients recruited from North America, Europe, and Japan and the relative differences in patient outcomes according to the site recruitment volume.

Clinically Optimal Neuropsychological Tests for Postoperative Cognitive Dysfunction in Heart Valve Surgeries.

Background: Postoperative cognitive dysfunction (POCD) is widely recognized and reported, but the lack of a uniform definition makes it difficult to evaluate its clinical impact. The aim of this study is to establish the optimal neuropsychological tests and definition of POCD relevant to clinical outcomes in heart valve surgeries.

Methods and results: Between June 2015 and December 2019, 315 patients undergoing elective heart valve surgeries (age ≥65 years) were enrolled.

Clinical impact of beta-blockers at discharge on long-term clinical outcomes in patients with non-reduced ejection fraction after acute myocardial infarction.

Background: Beta-blockers are associated with several clinical benefits in patients with reduced left ventricular ejection fraction (REF) after acute myocardial infarction (AMI), such as lower rates of mortality, recurrence of myocardial infarction, and heart failure. However, the long-term prognosis of beta-blockers has rarely been investigated in patients with non-REF after AMI. This study aimed to investigate the clinical benefits of beta-blockers in these patients.
