BACKGROUND: Implantable cardioverter defibrillators (ICDs) are lifesaving devices for patients with heart failure (HF) and reduced ejection fraction. However, utilization and determinants of ICD insertion in Asia are poorly defined. We determined the utilization, associations of ICD uptake, patient-perceived barriers to device therapy and, impact of ICDs on mortality in Asian patients with HF. METHODS AND RESULTS: Using the prospective ASIAN-HF (Asian Sudden Cardiac Death in Heart Failure) registry, 5276 patients with symptomatic HF and reduced ejection fraction (HFrEF) from 11 Asian regions and across 3 income regions (high: Hong Kong, Japan, Korea, Singapore, and Taiwan; middle: China, Malaysia, and Thailand; and low: India, Indonesia, and Philippines) were studied...

Heart failure (HF) is a common condition affecting predominantly older people. Symptoms include breathlessness and fatigue, and can significantly reduce quality of life. HF rarely occurs in isolation, with most patients having several co-existing diseases requiring multiple medications. There is a large evidence base for treatment of HF with reduced ejection fraction, or HFrEF; however, many of the trials did not include older people with multimorbidity so their findings should be applied to this group with some caution...

AIMS: The most recent European guidelines have proposed new definitions of pulmonary hypertension (PH) in left heart disease, to better approach the characteristics required to reflect the presence of pulmonary vascular disease. The purpose of this study was to assess whether different haemodynamic definitions of post-capillary PH imply a different reversibility of PH in response to acute vasodilator administration in heart failure patients with reduced ejection fraction and PH (HFrEF-PH)...

BACKGROUND: Blockade of the renin-angiotensin system (RAS) represents a main strategy in the therapy of heart failure with reduced ejection fraction (HFrEF), but the role of active renin concentration (ARC) for guiding therapy in the presence of an RAS blockade remains to be established. This study assessed angiotensin profiles of HFrEF patients with distinct RAS activations as reflected by ARC. METHODS: Two cohorts of stable chronic HFrEF patients on optimal medical treatment (OMT) were enrolled...

BACKGROUND: The diagnosis of heart failure (HF) remains difficult. A wide variety of studies have indicated that microRNAs play important roles in the pathophysiology of HF. HYPOTHESIS: Circulating miRNAs may be the potential biomarkers for HF. METHODS: In this study, a genome-wide plasma miRNA expression analysis was performed in thirteen HF patients and three controls. Microarray was used for the initial screen, followed by validation with quantitative real-time PCR (qRT-PCR) assays in an independent cohort of thirty-three HF patients and twenty controls...

The majority of older adults who develop heart failure (HF), particularly older women, have a preserved left ventricular ejection fraction (HFpEF). The prevalence of this syndrome is increasing, and the prognosis is not improving, unlike that of HF with reduced ejection fraction (HFrEF). Individuals with HFpEF have severe symptoms of effort intolerance, poor quality of life, frequent hospitalizations, and greater likelihood of death. Despite the importance of HFpEF, there are numerous major gaps in our understanding of its pathophysiology and management...

BACKGROUND: Heart failure (HF) is common among skilled nursing facility (SNF) residents, yet patients with HF in the SNF setting have not been well described. METHODS: Using Minimum Data Set 3.0 cross-linked to Medicare data (2011-2012), we studied 150,959 HF patients admitted to 13,858 SNFs throughout the USA. ICD-9 codes were used to differentiate patients with HF with preserved ejection fraction (HFpEF), reduced ejection fraction (HFrEF), or unspecified HF. RESULTS: The median age of the study population was 82 years, 68% were women, 34% had HFpEF, and 27% had HFrEF...

The limited myocardial fibre thickening and shortening alone cannot explain the marked left ventricular (LV) volume reduction during LV ejection. This can only be achieved with LV helical (spiral) orientation of myocardial fibres, which is determined by the non-contractile LV myocardial components (intrasarcomeric and extrasarcomeric cytoskeleton, extracellular matrix). Preservation of LV ejection fraction (LVEF) in heart failure (HF) is due to the presence of normal ellipsoid LV configuration and spiral myocardial fibre orientation...

People with heart failure experience marked reduction in their exercise capacity which has detrimental effects on their activities of daily living, health-related quality of life, and ultimately their hospital ad-mission rate and mortality. Numerous cardiac rehabilitation studies have demonstrated functional benefits, improvement in quality of life and clinical outcomes from exercise training in patients with HFrEF. Based on evidences, the American College of Cardiology/American Heart Association, European Society of Cardiology, and National Institute for Health and Care Excellence(NICE) consistently recommend exercise-based cardiac rehabilitation(CR) as an effective and safe adjunct for patients with stable class II to III heart failure (HF) who do not have advanced arrhythmias and who do not have other limitations to exercise...

Diagnosis, prognosis, treatment, and development of new therapies for diseases or syndromes depend on a reliable means of identifying phenotypes associated with distinct predictive probabilities for these various objectives. Left ventricular ejection fraction (LVEF) provides the current basis for combined functional and structural phenotyping in heart failure by classifying patients as those with heart failure with reduced ejection fraction (HFrEF) and those with heart failure with preserved ejection fraction (HFpEF)...

BACKGROUND: This study aimed to compare the independent and incremental prognostic value of peak oxygen consumption (VO2) and minute ventilation/carbon dioxide production (VE/VCO2) in heart failure (HF) with preserved (HFpEF), midrange (HFmEF), and reduced (HFrEF) ejection fraction (LVEF). METHODS AND RESULTS: In 195 HFpEF (LVEF ≥50%), 144 HFmEF (LVEF 40-49%), and 630 HFrEF (LVEF <40%) patients, we assessed the association of cardiopulmonary exercise testing variables with the composite outcome of death, left ventricular assist device implantation, or heart transplantation (256 events; median follow-up of 4...

The CHADS2, CHA2DS2-VASc, and R2CHADS2 scores are well-known predictors of stroke caused by atrial fibrillation (AF), but no studies have evaluated their use for stratifying all-cause mortality risk in patients discharged for systolic heart failure (SHF) with or without AF.This study analyzed data in the Taiwan Society of Cardiology-heart failure with reduced ejection fraction (TSOC-HFrEF) registry. These data were obtained by a prospective, multicenter, observational survey of patients treated at 21 medical centers in Taiwan after hospitalization for acute, pre-existing or new onset SHF from May, 2013 to October, 2014...

The 2016 European Society of Cardiology heart failure guidelines introduced the term 'heart failure with mid-range ejection fraction' (HFmrEF) to refer to patients with heart failure and a mildly reduced ejection fraction of 40-49%. About 20% of heart failure patients fall in this category. One of the main reasons for the introduction of this category was to stimulate research into this grey area. This review aims to highlight the key findings that have been published so far. Firstly, HFmrEF more closely resembles heart failure with reduced (HFrEF) than preserved ejection fraction (HFpEF) with regard to ischaemic aetiology, which is more frequent in both HFmrEF and HFrEF compared to HFpEF...

Heart failure (HF) is classified into three clinical subtypes: HF with a preserved ejection fraction (HFpEF: EF ≥ 50%), HF with a mid-range ejection fraction (HFmrEF: 40 ≤ EF < 49%), and HF with a reduced ejection fraction (HFrEF: EF < 40%). These types often coexist with atrial fibrillation (AF). We investigated the rate of strokes/systemic embolisms (SSEs) in AF patients with HFpEF (AF-HFpEF) compared to that in those with HFrEF (AF-HFrEF: HFmrEF and HFrEF), and examined the independent predictors...

AIMS: Chronic obstructive pulmonary disease (COPD) and heart failure (HF) are increasingly frequent in Asia and commonly coexist in patients. However, the prevalence of COPD among Asian patients with HF and its impact on HF treatment are unclear. METHODS AND RESULTS: We compared clinical characteristics and treatment approaches between patients with or without a history of COPD, before and after 1:2 propensity matching (for age, sex, geographical region, income level, and ethnic group) in 5232 prospectively recruited patients with HF and reduced ejection fraction (HFrEF, <40%) from 11 Asian regions (Northeast Asia: South Korea, Japan, Taiwan, Hong Kong, and China; South Asia: India; Southeast Asia: Thailand, Malaysia, Philippines, Indonesia, and Singapore)...

The hallmark symptom of chronic heart failure (CHF) syndrome is severe exercise intolerance. Impaired perfusive and diffusive O2 transport are two of the major determinants of reduced physical capacity and lowered maximal O2 uptake (VO2max) in CHF patients. It has now become evident that this syndrome manifests two different phenotypic variations: heart failure with preserved or reduced ejection fraction (HFpEF and HFrEF, respectively). Unlike HFrEF, however, there is currently limited understanding of HFpEF pathophysiology leading to a lack of effective pharmacological treatments for this subpopulation...

INTRODUCTION: Heart failure (HF) is a common and a serious condition that predominantly affects elderly people. On the basis of the left ventricular ejection fraction (EF) it can be divided into HF with reduced or preserved ejection fraction (HFrEF and HFpEF, respectively). The goal of this study was to investigate the prevalence and incidence of HF among elderly Icelanders, explore underlying diseases and estimate the effect of HF on overall survival.

With an estimated prevalence of 5.8 million in the USA and over 23 million people worldwide, heart failure (HF) is growing in epidemic proportions. Despite the use of guideline-directed medical therapies such as angiotensin-converting enzyme inhibitors, beta-adrenergic blockers, angiotensin receptor blockers, and mineralocorticoid receptor antagonists for chronic systolic HF for almost two decades, HF remains a leading cause of morbidity, mortality, and health care expenditures. The Prospective Comparison of Angiotensin Receptor-Neprilysin Inhibitor with Angiotensin-Converting Enzyme Inhibitor to Determine Impact on Global Mortality and Morbidity in Heart Failure (PARADIGM-HF) trial provided compelling evidence for the cardiovascular and mortality benefit of sacubitril/valsartan when compared to enalapril in patients with heart failure and reduced ejection fraction (HFrEF)...
