OBJECTIVES: This study sought to evaluate the prognostic value of mean pressure gradient (MPG) increase and peak systolic pulmonary artery pressure (SPAP) measured during exercise stress echocardiography in asymptomatic patients with aortic stenosis (AS). BACKGROUND: Exercise testing is recommended in asymptomatic AS patients, but the additional value of exercise-stress echocardiography, especially the prognostic value of MPG increase and peak SPAP, is still debated...

BACKGROUND: Little information is available about the prevalence and impact on exercise capacity and outcome of iron deficiency in heart failure with mid-range (HFmrEF) and preserved (HFpEF) ejection fraction in comparison to heart failure with reduced ejection-fraction (HFrEF). Furthermore, no data is available about the progression of ID in patients without baseline anaemia. METHODS: We evaluated baseline iron and haemoglobin-status in a single-centre, prospective heart failure database...

INTRODUCTION: Systolic blood pressure (SBP) is emerging as a predictor of outcome in chronic heart failure and low SBP has been shown to be related to higher mortality. AIM: To investigate the relationship between low SBP and long-term outcome in patients with heart failure with preserved ejection fraction (HFpEF). METHODS: We use prospectively collected data and recruited 297 patients with chronic HFpEF to investigate the relationship between low SBP at discharge and long-term outcome...

OBJECTIVES: This study was designed to detect differences in markers associated with incident heart failure preserved ejection fraction (HFpEF) when comparing matched case-control groups. BACKGROUND: Evidence continues to demonstrate increasing prevalence, cost and mortality implications of HFpEF, but clearly defined parameters that distinguish between controls and HFpEF have not been established. METHODS: A study cohort of case (incident patients with HFpEF, n=155) and matched control (patients with no prior HF, n=155) groups was retrospectively identified...

Obesity increases the risk of heart failure (HF), which continues to be a significant proportion of all cardiovascular diseases and affects increasingly younger populations. The cross-talk between adipose and the heart involves insulin resistance, adipokine signaling and inflammation, with the capacity of adipose tissue to mediate hemodynamic signals, promoting progressive cardiomyopathy. Areas covered: From a therapeutic perspective, there is not yet a single obesity-related pathway that when addressed, can ameliorate cardiomyopathy in obese patients and this is a matter of ongoing research...

BACKGROUND/INTRODUCTION: Risk stratification in chronic heart failure (HF) remains a challenge. Renal function and B-natriuretic peptide (BNP) might confer predictive value towards long-term mortality in HF patients after an acute coronary syndrome (ACS). METHODS: From May 2006 to March 2009, 1,000 consecutive patients who were hospitalized with ACS diagnosis were enrolled in the study. In 2016, the 10-year follow-up (2006-2016) was performed in 745 participants...

OBJECTIVES: The study sought to assess the independent risk factors for, consequences of, and outcomes with atrial fibrillation (AF) compared with sinus rhythm (SR) in heart failure (HF) with preserved ejection fraction (HFpEF) versus HF with mid-range ejection fraction (HFmrEF) versus HF with reduced ejection fraction (HFrEF). BACKGROUND: AF is common in HF, but most data are from HFrEF. The importance of AF in HFpEF and MFmrEF is less well known. METHODS: In patients from 2000 to 2012 in the SwedeHF (Swedish Heart Failure Registry) registry, enriched with patient-level data from national health care registries, the authors assessed prevalence of, associations with and prognostic impact of AF in HFpEF versus HFmrEF versus HFrEF...

OBJECTIVES: The goal of this study was to assess: 1) the intrarenal flow in heart failure (HF) patients during the transition from euvolemia to intravascular volume overload; and 2) the relationship between intrarenal flow and diuretic efficiency. BACKGROUND: Intrarenal blood flow alterations may help to better understand impaired volume handling in HF. METHODS: Resistance index (RI) and venous impedance index (VII) were assessed in 6 healthy subjects, 40 euvolemic HF patients with reduced ejection fraction (HFrEF) and 10 HF patients with preserved ejection fraction (HFpEF)...

Longstanding hypertension ultimately leads to heart failure (HF), and as a consequence most patients with HF have a history of hypertension. Conversely, absence of hypertension in middle age is associated with lower risks for incident HF across the remaining life course. Cardiac remodeling to a predominant pressure overload consists of diastolic dysfunction and concentric left ventricular (LV) hypertrophy. When pressure overload is sustained, diastolic dysfunction progresses, filling of the concentric remodeled LV decreases, and HF with preserved ejection fraction ensues...

BACKGROUND: Recent experimental data indicate a pathogenic role of complement activation in congestive heart failure (CHF). Aim of this study was to evaluate contact and complement systems activation in patients hospitalized for an acute episode of CHF. METHODS AND RESULTS: 42 of 80 consecutive patients admitted at our hospital with confirmed diagnosis of acute CHF were enrolled. They underwent blood sampling within 24 hours from admission (T0) and at clinical stability (T1)...

Functional tricuspid regurgitation (TR) is a serious pathology to be noted for severe right heart failure (HF) and poor prognosis; however, the conventional assessment of TR has some limitations and the optimal timing of surgical intervention remains unclear. A 79-year-old Japanese female was admitted to our hospital to undergo cardiac surgery, because edema gradually got worse despite the increase in diuretics. She had a history of atrial fibrillation (AF) and chronic HF due to severe TR and had been treated with a furosemide for leg edema 4 years ago...

Although the burden of heart failure with preserved ejection fraction (HFpEF) is increasing, there is no therapy available that improves prognosis. Clinical trials using beta blockers and angiotensin converting enzyme inhibitors, cardiac-targeting drugs that reduce mortality in heart failure with reduced ejection fraction (HFrEF), have had disappointing results in HFpEF patients. A new "whole-systems" approach has been proposed for designing future HFpEF therapies, moving focus from the cardiomyocyte to the endothelium...

Transverse tubules (t-tubules) are uniquely-adapted membrane invaginations in cardiac myocytes that facilitate the synchronous release of Ca(2+) from internal stores and subsequent myofilament contraction, although these structures become disorganized and rarefied in heart failure. We previously observed that mitsugumin 29 (Mg29), an important t-tubule organizing protein in skeletal muscle, was induced in the mouse heart for the first time during dilated cardiomyopathy with heart failure. Here we generated cardiac-specific transgenic mice expressing Mg29 to model this observed induction in the failing heart...

BACKGROUND: Among central and peripheral factors contributing to exercise intolerance (EI) in heart failure (HF), the extent to which skeletal muscle (SM) energy metabolic abnormalities occur and contribute to EI and increased fatigability in HF patients with reduced or preserved ejection fraction (HFrEF and HFpEF, respectively) are not known. An energetic plantar flexion exercise fatigability test and magnetic resonance spectroscopy were used to probe the mechanistic in vivo relationships among SM high-energy phosphate concentrations, mitochondrial function, and EI in HFrEF and HFpEF patients and in healthy controls...

OBJECTIVE: Fstl1 (Follistatin-like 1) is a secreted protein that is expressed in the atrioventricular valves throughout embryonic development, postnatal maturation, and adulthood. In this study, we investigated the loss of Fstl1 in the endocardium/endothelium and their derived cells. APPROACH AND RESULTS: We conditionally ablated Fstl1 from the endocardial lineage using a transgenic Tie2-Cre mouse model. These mice showed a sustained Bmp and Tgfβ signaling after birth...

The aim of this study was to evaluate the association of functional mitral regurgitation (FMR), preserved or reduced ejection fraction (EF), and ischemic or nonischemic origin with outcomes in patients discharged alive after hospitalization for acute decompensated heart failure (HF). Of the 4,842 patients enrolled in the Acute Decompensated Heart Failure Syndromes (ATTEND) registry, 3,357 patients were evaluated to assess the association of FMR, preserved or reduced EF, and ischemic or nonischemic origin with the primary end point (all-cause death and readmission for HF after discharge)...

AIMS: Worsening renal function (WRF) occurs in one-third of patients hospitalized for acute decompensated heart failure. Recently, WRF was categorized in two subtypes: persistent and transient WRF. Thus, we sought to investigate the different prognostic impact of persistent vs. transient WRF; we also evaluate the relation of two WRF phenotypes with congestion, B-type natriuretic peptide (BNP) changes, and diuretic response at discharge. METHODS: The prospective was a single centre study including patients screened for interventional Diur-heart failure Trial (NCT01441245)...

Despite the high mortality rate, there is no therapy to improve survival in heart failure with preserved ejection fraction (HFpEF). Large randomized controlled trials (RCTs) did not show clear mortality benefit of renin-angiotensin system (RAS) inhibitors (angiotensin-converting enzyme inhibitors or angiotensin receptor blockers) in HFpEF. However, because of the strict enrollment criteria, the patients who participated in these trials might represent a selected group of patients that is poorly representative of patients treated in routine clinical practice...

Kazuhiro Yamamoto
Heart failure with preserved ejection fraction is a socioeconomic burden in Japan as well as other developed countries. Diuretics are widely used to attenuate symptoms and signs of congestion in both heart failure with preserved and reduced ejection fraction, although their effects on long-term prognosis of both phenotypes of heart failure have not been demonstrated because of an ethical difficulty in designing a randomized and prospective clinical trial. Guidelines do not provide any guidance on therapy choice, and physicians blindly choose furosemide among loop diuretics in current clinical settings...
