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...

A single heart rate (HR) measurement may inform future prognosis in chronic heart failure with reduced ejection fraction (HFrEF). The importance of elevated HR across serial assessment is uncertain, particularly with well-applied guideline-directed medical therapy (GDMT) with beta blockers (BBs). In this post hoc analysis of 129 patients with chronic HFrEF in sinus rhythm, who had aggressive medication titration over 10.6 months, HR and BB use were assessed at each visit (average of 6 visits per patient). All-cause mortality was assessed...

BACKGROUND AND AIM: The objective of this study was to assess the potential role of mitral regurgitation (MR) in the release of copeptin in HF patients with reduced ejection fraction (HFREF). METHODS: The study included 63 patients of whom 33 had functional mild MR (Group 1) and 30 had functional severe MR (Group 2).The functional classes of the groups were both NYHA Class III. Blood samples for the determination of plasma copeptin and B-type natriuretic peptide (BNP) levels were obtained at the same day with the echocardiographic examination...

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)...

Patients with heart failure (HF) and reduced ejection fraction (HFREF) are at increased risk of death and hospitalizations for HF. Numerous registries have reported a large and persistent gap between real-life practice in the use of life-saving evidence-based therapies, such as renin angiotensin system inhibitors, beta blockers, mineralocorticoid receptor antagonists (MRAs), and recommended practices in international guidelines. The fears of inducing hyperkalemia and/or worsening renal function are the main triggers of this underuse...

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...

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...

The impact of heart failure (HF) on long-term survival in patients with critical limb ischemia (CLI) has not been well described. Outcomes stratified by left ventricular ejection fraction (EF) are also unknown. A single center retrospective chart review was performed for patients who underwent treatment for CLI from 2006 to 2013. Baseline demographics, procedural data and outcomes were analyzed. HF diagnosis was based on appropriate signs and symptoms as well as results of non-invasive testing. Among 381 CLI patients, 120 (31%) had a history of HF and 261 (69%) had no history of heart failure (no-HF)...

Heart Failure (HF) results in high healthcare costs and burdens for the United States both in respects to hospitalizations, therapies, and associated disability. The relative proportion of HF with preserved ejection fraction (HFpEF) compared with HF with reduced ejection fraction (HFrEF) is on the rise; HFpEF has already become the dominant form of HF and it continues to increase. The serious implications of these trends are compounded by a dearth of effective HFpEF therapies. While low physical activity, low cardiorespiratory fitness (CRF), and obesity, are risk factors for HF in general, they particularly predispose to HFpEF...

The beneficial effects of angiotensin converting enzyme (ACE) inhibitors and angiotensin II (AII) receptor antagonists in patients with heart failure secondary to reduced ejection fraction (HFrEF) are felt to result from prevention of the adverse effects of AII on systemic afterload and renal homeostasis. However, AII can activate the sympathetic nervous system and part of the beneficial effects of ACE inhibitors and AII antagonists may result from their ability to inhibit such activation. We examined the acute effects of the ACE inhibitor captopril (25 mg, n = 9) and the AII receptor antagonist losartan (50 mg, n = 10) on hemodynamics as well as total body and cardiac norepinephrine spillover in patients with chronic HFrEF...

Heart failure with preserved ejection fraction (HFpEF) makes up half of diagnosed heart failure cases and has similar outcomes compared to heart failure with reduced ejection fraction (HFrEF) but a discrepancy in knowledge and approach to treatment. HFpEF is diagnosed using the following criteria: symptoms, preserved ejection fraction (greater than 50%), and evidence of abnormal left ventricular filling or relaxation, or diastolic distensibility or stiffness. Studies conducted to examine the efficacy of angiotensin receptor blockers (irbesartan and candesartan), thiazide diuretics (chlorthalidone), and angiotensin converting enzyme inhibitors (perindopril) in the treatment of HFpEF, showed moderate efficacy but no clear benefit...

BACKGROUND: Regular physical activity is recommended for patients with chronic heart failure to improve their functional capacity, and walking is a popular, effective, and safe form of physical activity. Pedometers have shown potential to increase the amount of walking across a range of chronic diseases, but it is unknown whether a pedometer-based intervention improves functional capacity and neurohumoral modulation in heart failure patients. METHODS: Two multicenter randomized controlled trials will be conducted in parallel: one in patients with chronic heart failure with reduced ejection fraction (HFrEF), the other in patients with chronic heart failure with preserved ejection fraction (HFpEF)...

PURPOSE: Exercise training has been shown to reduce combined cardiovascular mortality and hospitalizations in patients with chronic heart failure (CHF) with reduced ejection fraction (HFrEF). Whereas there are extensive data on exercise training for individuals with HFrEF in a research setting, the experience of delivering cardiac rehabilitation (CR) services in the clinical setting has not been well described. With little knowledge regarding the number of qualifying patients with HFrEF in the United States, we described our 18-month experience recruiting hospitalized inpatients and stable outpatients into phase 2 CR...

Obstructive sleep apnoea (OSA) is frequently undiagnosed in patients with heart failure (HF) and coronary artery disease (CAD). Simple and widely available screening tests are needed to diagnose patients with SA. Measurements of thoracic impedance and heart rate variability during 24-hour ECG Holter (H-EKG) monitoring allows to calculate estimated apnoea-hypopnoea index (eAHI). AIM: The aim of the research was to assess prevalence of OSA evaluated with the use of H-EKG and determination of its clinical relevance in patients with CAD and ischeamic HF...

PURPOSE OF REVIEW: The current definition of heart failure is mainly based on an inappropriate measure of cardiac function, i.e., left ventricular ejection fraction (LVEF). The initial sole entity, heart failure with reduced ejection fraction (HFrEF, LVEF <40%), was complemented by the addition of heart failure with preserved ejection fraction (HFpEF, LVEF ≥50%) and most recently, heart failure with mid-range ejection fraction (HFmrEF, LVEF 40-49%). Initially, HFpEF was believed to be a purely left ventricular diastolic dysfunction...
