Heat stress evokes significant increases in muscle sympathetic nerve activity (MSNA) in healthy individuals. The MSNA response to heat stress in chronic heart failure (CHF) is unknown. We hypothesized that the MSNA response to heat stress is attenuated in CHF. Passive whole body heating was applied with water-perfused suits on 13 patients (61 ± 2 years) with stable class II-III CHF, 12 age-matched (62 ± 2 years) healthy subjects, and 14 young (24 ± 1 years) healthy subjects. Mild heating (i.e. increases in skin temperature ΔTsk ~2-4 °C, internal temperature ΔTcore <0...

Introduction: Despite clear guidelines recommendations, most patients with heart failure and reduced ejection-fraction (HFrEF) do not attain guideline-recommended target doses. We aimed to investigate characteristics and for treatment-indication-bias corrected clinical outcome of patients with HFrEF that did not reach recommended treatment doses of ACE-inhibitors/Angiotensin receptor blockers (ARBs) and/or beta-blockers. Methods and results: BIOSTAT-CHF was specifically designed to study uptitration of ACE-inhibitors/ARBs and/or beta-blockers in 2516 heart failure patients from 69 centres in 11 European countries who were selected if they were suboptimally treated while initiation or uptitration was anticipated and encouraged...

Hydroxychloroquine, due to its multifaceted pleiotropic benefits including anti-inflammatory effects has great potential in reducing cardiovascular (CV) morbidity and mortality. CV outcome data of hydroxychloroquine is available through 2 retrospective studies in rheumatoid arthritis patients, both of which have not considered congestive heart failure (CHF) as an outcome measure. CHF is an important CV outcome and is more common than myocardial infarction and stroke; and increased age is associated with increased risk of CHF...

Considering the polysaccharide composition and 32% of crystallinity of the water insoluble fiber extracted from corn husk (CHF) agricultural residue, its filler performance as water vapor permeability (WVP) and mechanical modifier in edible films based on commercial low methoxyl pectin (LMP) was evaluated (0, 1, 3, 5, 8% concentrations). The 53-μm-CHF carried phenolics and carotenes, and composites showed antioxidant capacity. Homogeneous films with a continuous LMP matrix were obtained. The 5%-CHF composite showed the highest surface contact angle (44°) and tensile strength, without change in elongation, while WVP was decreased in the 3-8% CHF-LMP-films...

Long-term continuous patient monitoring is required in many health systems for monitoring and analytical diagnosing purposes. It has been recognized that these types of monitoring systems have shortcomings related to patient comfort and/or functionality. Non-contact monitoring systems have been developed to address some of these shortcomings. One of such systems is non-contact physiological vital signs assessments for Chronic Heart Failure (CHF) patients. This paper presents a novel pulmonary ventilation model that defines the relationship between the intrapulmonary pressure and the chest displacement...

INTRODUCTION: Chronic heart failure (CHF) is a major public health concern. From a public health perspective, the epidemiology of CHF needs to be distinguished from that of its related acute form. Data stemming from primary care are crucial to better know and update the prevalence and incidence rates of CHF. AIM: To update the epidemiology of CHF in an Italian primary care setting and to describe socio-demographic, lifestyle, and clinical characteristics of these patients...

Although adaptive servo-ventilation (ASV) therapy has beneficial effects on chronic heart failure (CHF), a relatively large number of CHF patients cannot undergo ASV therapy due to general discomfort from the mask and/or positive airway pressure. The present study aimed to clarify baseline patient characteristics which are associated with the smooth introduction of ASV treatment in stable CHF inpatients.Thirty-two consecutive heart failure (HF) inpatients were enrolled (left ventricular ejection fraction (LVEF) < 45%, estimated glomerular filtration rate (eGFR) > 10 mL/minute/1...

BACKGROUND: Treatment with renin-angiotensin system (RAS) inhibitors might restrain the structural/electrical remodeling associated with atrial fibrillation (AF). Limited evidence exists regarding the potential benefits of RAS inhibition post-acute myocardial infarction (AMI) in patients with AF. This study sought to assess the association between RAS inhibition and all-cause mortality and new-onset AF in patients with/without congestive heart failure (CHF) post-AMI. METHODS AND RESULTS: Patients hospitalized for AMI between 2006 and 2012 were identified in Swedish registries...

BACKGROUND: Improving the management of patients with complex chronic disease is a substantial undertaking with the simultaneous goals of improving patient outcomes and controlling costs. Reducing avoidable hospitalization for such patients is a step toward both objectives. Some of the deterioration experienced in chronic disease patients occurs outside the view of their clinicians, and before the patient becomes overtly symptomatic. Home monitoring has been used for more than 20 years to detect deterioration earlier so that the patients could be treated before they became ill enough to require hospitalization...

Evidence-based guidelines recommend exercise therapy for patients with chronic heart failure (CHF). Such patients have increased atherothrombotic risk. Exercise can transiently increase platelet activation and reactivity and decrease vascular function in healthy participants, although data in CHF is scant. Eccentric (ECC) cycling is a novel exercise modality which may be particularly suited to patients with CHF, but the acute impacts of ECC on platelet and vascular function are currently unknown. Our null hypothesis was that ECC and concentric (CON) cycling, performed at matched external workloads, would not induce changes in platelet or vascular function in patients with CHF...

BACKGROUND: In patients with acute heart failure (AHF), dyspnea relief is the most immediate goal. Renal dysfunction, diuretic resistance, and hyponatremia represent treatment impediments. OBJECTIVES: It was hypothesized that the addition of tolvaptan to a background diuretic improved dyspnea early in patients selected for an enhanced vasopressin antagonism response. METHODS: In a double-blind trial, patients were randomized to tolvaptan 30 mg/day or placebo...

INTRODUCTION: Leptin is an adipose tissue-derived hormone associated with cardiovascular risk factors. We examined whether leptin predicts major adverse cardiac events (MACE) in coronary artery disease (CAD) patients. METHODS: Fasting plasma leptin levels were measured in 1327 male and 619 female CAD patients. The patients were followed up for two years. The primary endpoint (MACE) was the composite of a hospitalisation for congestive heart failure (CHF) or a cardiac death...

AIMS: While the conditions of heart failure (HF) with reduced (HFrEF, LVEF < 40%) and preserved (HFpEF, LVEF ≥ 50%) left ventricular ejection fraction (LVEF) are well characterized, it is unknown whether patients with HF and mid-range LVEF (HFmrEF, LVEF 40-49%) have to be regarded as a separate clinical entity. The aim of this study was to characterize these three populations and to compare outcome and response to therapy. METHODS AND RESULTS: The analysis was based on the Trial of Intensified versus standard Medical therapy in Elderly patients with Congestive Heart Failure (TIME-CHF) comprising a population with established HF including the whole spectrum of LVEF...
