The evolutionarily conserved Hippo pathway plays a pivotal role in governing a variety of biological processes. Heart failure (HF) is a major global health problem with a significant risk of mortality. This review provides a contemporary understanding of the Hippo pathway in regulating different cell types during HF. Through a systematic analysis of each component's regulatory mechanisms within the Hippo pathway, we elucidate their specific effects on cardiomyocytes, fibroblasts, endothelial cells, and macrophages in response to various cardiac injuries...

BACKGROUND: Reduced exercise capacity is a prognostic indicator of adverse outcomes in patients with acute myocardial infarction (AMI). However, few studies have evaluated the effectiveness of comprehensive cardiac rehabilitation (CR) in this population. This study aimed to clarify the efficacy of comprehensive CR in patients with AMI and reduced exercise capacity.Methods and Results: This cohort study included 610 patients with AMI who underwent percutaneous coronary intervention...

BACKGROUND: Foam cell formation is an important step for atherosclerosis (AS) progression. We investigated the mechanism by which the long non-coding RNA (lncRNA) nuclear-enriched abundant transcript 1 (NEAT1) regulates foam cell formation during AS progression.Methods and Results: An in vivo AS model was created by feeding ApoE-/- mice a high-fat diet. Oxidized low-density lipoprotein (ox-LDL)-stimulated macrophages were used as a cellular AS model. Interactions between NEAT1, miR-17-5p, itchy E3 ubiquitin protein ligase (ITCH) and liver kinase B1 (LKB1) were analyzed...

BACKGROUND: We determined the left ventricular end-systolic diameter (LVDs) cut-off value for risk of major adverse cardiac and cerebrovascular events (MACCE) in Japanese asymptomatic or mildly symptomatic patients undergoing aortic valve replacement (AVR) for aortic valve regurgitation (AR), and investigated the effect of left ventricular dilation on long-term postoperative outcomes.Methods and Results: The 168 patients who underwent surgical AVR for AR at Shiga University of Medical Science between January 2002 and December 2022 were included in this study...

BACKGROUND: Despite an increased incidence of chronic heart failure (HF) and sudden cardiac death (SCD), the use of implantable cardioverter-defibrillators (ICDs) and cardiac resynchronization therapy (CRT) is much lower in Japan than in Western countries. The HF Indication and SCD Prevention Trial Japan (HINODE) prospectively assessed the mortality rate, appropriately treated ventricular arrhythmias (VA), and HF in Japanese patients with a higher risk of HF.Methods and Results: HINODE consisted of ICD, CRT-defibrillator (CRT-D), pacing, and non-device treatment cohorts...

BACKGROUND: Despite the widespread use of PROPATEN® , a bioactive heparin-bonded expanded polytetrafluoroethylene graft, in bypass surgery, there are only a few reports of long-term results. We evaluated the long-term results of PROPATEN® use for above-knee femoropopliteal bypass (AKFPB).Methods and Results: After PROPATEN® -based AKFPB, patients were prospectively registered at 20 Japanese institutions between July 2014 and October 2017 to evaluate long-term results...

BACKGROUND: Limited data exist regarding the prognostic implications of N-terminal pro-B-type natriuretic peptide (NT-proBNP) in patients with non-ST-elevation myocardial infarction (NSTEMI) who undergo percutaneous coronary intervention (PCI).Methods and Results: Of 13,104 patients in the nationwide Korea Acute Myocardial Infarction Registry-National Institutes of Health, 3,083 patients with NSTEMI who underwent PCI were included in the present study. The primary endpoint was major adverse cardiovascular events (MACE) at 3 years, a composite of all-cause death, recurrent myocardial infarction, unplanned repeat revascularization, and admission for heart failure...

BACKGROUND: Kampo, a Japanese herbal medicine, is approved for the treatment of various symptoms/conditions under national medical insurance coverage in Japan. However, the contemporary nationwide status of Kampo use among patients with acute cardiovascular diseases remains unknown.Methods and Results: Using the Japanese Diagnosis Procedure Combination database, we retrospectively identified 2,547,559 patients hospitalized for acute cardiovascular disease (acute myocardial infarction, heart failure, pulmonary embolism, or aortic dissection) at 1,798 hospitals during the fiscal years 2010-2021...

BACKGROUND: Hypertension is a major cause of cardiovascular disease (CVD). In patients with hypertension, unawareness of the disease often results in poor blood pressure control and increases the risk of CVD. However, data in nationwide surveys regarding the proportion of unaware individuals and the implications of such on their clinical outcomes are lacking. We aimed to clarify the association between unawareness of being prescribed antihypertensive medications among individuals taking antihypertensive medications and the subsequent risk of developing CVD...

BACKGROUND: The safety and feasibility of using 1-month dual antiplatelet therapy (DAPT) followed by P2Y12 inhibitor monotherapy for patients after percutaneous coronary intervention (PCI) with thin-strut biodegradable polymer drug-eluting stents (BP-DES) in daily clinical practice remain uncertain.Methods and Results: The REIWA region-wide registry is a prospective study conducted in 1 PCI center and 9 local hospitals in northern Japan. A total of 1,202 patients who successfully underwent final PCI using BP-DES (Synergy: n=400; Ultimaster: n=401; Orsiro: n=401), were enrolled in the registry, and received 1-month DAPT followed by P2Y12 inhibitor (prasugrel 3...

BACKGROUND: This study investigated whether the chronic use of adaptive servo-ventilation (ASV) reduces all-cause mortality and the rate of urgent rehospitalization in patients with heart failure (HF).Methods and Results: This multicenter prospective observational study enrolled patients hospitalized for HF in Japan between 2019 and 2020 who were treated either with or without ASV therapy. Of 845 patients, 110 (13%) received chronic ASV at hospital discharge. The primary outcome was a composite of all-cause death and urgent rehospitalization for HF, and was observed in 272 patients over a 1-year follow-up...
