Sample records for acute heart failure

  1. Acute heart failure syndrome

    African Journals Online (AJOL)

    Heart failure can be defined as a clinical syndrome in which a structural or functional cardiac abnormality impairs the capacity of the ventricle to fill or eject enough blood for the requirements of the body. Acute heart failure syndrome represents a complex, heterogeneous set of clinical conditions, all with the common.

    The care of patients with acutely decompensated heart failure is being reshaped by the availability and understanding of several novel and emerging heart failure biomarkers. The gold standard biomarkers in heart failure are B-type natriuretic peptide and N-terminal pro-B-type natriuretic peptide, which play an important role in the diagnosis, prognosis, and management of acute decompensated heart failure. Novel biomarkers that are increasingly involved in the processes of myocardial injury, neurohormonal activation, and ventricular remodeling are showing promise in improving diagnosis and prognosis among patients with acute decompensated heart failure. These include midregional proatrial natriuretic peptide, soluble ST2, galectin-3, highly-sensitive troponin, and midregional proadrenomedullin. There has also been an emergence of biomarkers for evaluation of acute decompensated heart failure that assist in the differential diagnosis of dyspnea, such as procalcitonin (for identification of acute pneumonia), as well as markers that predict complications of acute decompensated heart failure, such as renal injury markers. In this article, we will review the pathophysiology and usefulness of established and emerging biomarkers for the clinical diagnosis, prognosis, and management of acute decompensated heart failure.

    Acute heart failure is globally one of most frequent reasons for hospitalization and still represents a challenge for the choice of the best treatment to improve patient outcome. According to current international guidelines, as soon as patients with acute heart failure arrive at the emergency department, the common therapeutic approach aims to improve their signs and symptoms, correct volume overload, and ameliorate cardiac hemodynamics by increasing vital organ perfusion. Recommended treatment for the early management of acute heart failure is characterized by the use of intravenous diuretics, oxygen, and vasodilators. Although these measures ameliorate the patient's symptoms, they do not favorably impact on short- and long-term mortality. Consequently, there is a pressing need for novel agents in acute heart failure treatment with the result that research in this field is increasing worldwide.

    This article addresses issues related to acute myocardial infarction (MI) complicated by heart failure, particularly in elderly patients. Findings have shown that acute MI complicated by congestive heart failure (CHF) is associated with a high mortality, and that women with acute MI are more likely to be older and to develop CHF than men with acute MI. In general, management of CHF complicating acute MI is similar in older and younger patients. Actions discussed include hemodynamic monitoring; the administration of oxygen; and the use of morphine, diuretics, nitroglycerin, angiotensin-converting enzyme inhibitors, angiotensin II receptor blockers, spironolactone, beta-blockers, calcium channel blockers, magnesium, digoxin, and positive inotropic drugs. The article also discusses measures for treating arrhythmias and for diagnosing mechanical complications.

    Heart failure is one of the most common diseases of adults in Europe, with an overall prevalence of 1-2%. Among persons aged 60 and above, its prevalence is above 10% in men and 8% in women. Acute heart failure has a poor prognosis; it is associated with a high rate of rehospitalization and a 1-year mortality of 20-30%. This review is based on pertinent literature, including guidelines, retrieved by a selective search in PubMed. There are different types of acute heart failure; the basic diagnostic assessment is performed at once and consists of ECG, echocardiography, and the measurement of N-terminal pro-brain natriuretic peptide (NTproBNP) and troponin levels. The most common causes of decompensation are arrhythmia, valvular dysfunction, and acute cardiac ischemia, each of which accounts for 30% of cases. The potential indication for immediate revascularization should be carefully considered in cases where acute heart failure is due to coronary heart disease. The basic treatment of acute heart failure is symptomatic, with the administration of oxygen, diuretics, and vasodilators. Ino-tropic agents, vasopressors, and temporary mechanical support for the circulatory system are only used to treat cardiogenic shock. The treatment of acute heart failure is markedly less evidence-based than that of chronic heart failure. Newer treatment approaches that are intended to improve outcomes still need to be tested in multicenter trials.

    Acute right heart failure (RHF) is a frequent and severe complication during perioperative and intensive care treatment in intensive care units (ICUs). The most common causes are pulmonary hypertension, left heart failure, pulmonary embolism, sepsis, acute lung injury (ALI) and thoracosurgical procedures. Acute RHF is not only a major contributor to morbidity and mortality; it also influences efficacy and outcome of routinely performed procedures, such as vasopressors, in critically ill patients. In contrast to the left ventricle, the right ventricle's physiology and pathophysiology are understudied, and the diagnosis of acute RHF is frequently challenging. Although many drugs are available for the treatment of RHF, randomized trials for this setting are still missing. This article gives an overview of aetiology and pathogenesis of RHF and reviews the diagnostic and therapeutic interventions currently available for providers in anaesthesiology and critical care. © Georg Thieme Verlag Stuttgart · New York.

    Factors predisposing the older person with acute myocardial infarction (MI) to develop heart failure (HF) include an increased prevalence of MI, multivessel coronary artery disease, decreased left ventricular (LV) contractile reserve, impairment of LV diastolic relaxation, increased hypertension, LV hypertrophy, diabetes mellitus, valvular heart disease, and renal insufficiency. HF associated with acute MI should be treated with a loop diuretic. The use of nitrates, angiotensin-converting enzyme inhibitors, angiotensin II receptor blockers, aldosterone antagonists, beta-blockers, digoxin, and positive inotropic drugs; treatment of arrhythmias and mechanical complications; and indications for use of implantable cardioverter-defibrillators and cardiac resynchronization is discussed.

    Acute heart failure (AHF) is a life threatening clinical syndrome with a progressively increasing incidence in general population. Turkey is a country with a high cardiovascular mortality and recent national statistics show that the population structure has turned to an ‘aged’ population. As a consequence, AHF has become one of the main reasons of admission to cardiology clinics. This consensus report summarizes clinical and prognostic classification of AHF, its worldwide and national epidemiology, diagnostic work-up, principles of approach in emergency department, intensive care unit and ward, treatment in different clinical scenarios and approach in special conditions and how to plan hospital discharge.

    The purpose of this review is to describe the extent and scope of acute heart failure (AHF), place it within its clinical context and highlight some of the difficulties in defining it as a pathophysiological entity. A diagnosis of AHF is made when patients present acutely with signs and symptoms of heart failure, often with decompensation of pre-existing cardiomyopathy. The most current guidelines classify based on clinical features at initial presentation and are used to both risk stratify and guide the management of haemodynamic compromise. Despite this, AHF remains a diagnosis with a poor prognosis and there is no therapy proven to have long-term mortality benefits. We provide an introduction to AHF and discuss its definition, causes and precipitants. We also present epidemiological and demographic data to suggest that there is significant patient heterogeneity and that AHF is not a single pathology, but rather a range of pathophysiological entities. This poses a challenge when designing clinical trials and may, at least in part, explain why the results in this area have been largely disappointing.

    Full Text Available Abstract Congestive heart failure as a cause of acute liver failure is rarely documented with only a few cases. Although the pathophysiology is poorly understood, there is rising evidence, that low cardiac output with consecutive reduction in hepatic blood flow is a main causing factor, rather than hypotension. In the setting of acute liver failure due to congestive heart failure, clinical signs of the latter can be absent, which requires an appropriate diagnostic approach. As a reference center for acute liver failure and liver transplantation we recorded from May 2003 to December 2007 202 admissions with the primary diagnoses acute liver failure. 13/202 was due to congestive heart failure, which was associated with a mortality rate of 54%. Leading cause of death was the underlying heart failure. Asparagine transaminase (AST, bilirubin, and international normalized ratio (INR did not differ significantly in surviving and deceased patients at admission. Despite both groups had signs of cardiogenic shock, the cardiac index (CI was significantly higher in the survival group on admission as compared with non-survivors (2.1 L/min/m2 vs. 1.6 L/min/m2, p = 0.04. Central venous - and pulmonary wedge pressure did not differ significantly. Remarkable improvement of liver function was recorded in the group, who recovered from cardiogenic shock. In conclusion, patients with acute liver failure require an appropriate diagnostic approach. Congestive heart failure should always be considered as a possible cause of acute liver failure.

    Diuretics are widely recommended in patients with acute heart failure (AHF). Unfortunately, despite their widespread use, limited data are available from randomized clinical trials to guide clinicians on the appropriate management of diuretic therapy. Loop diuretics are considered the first-line diuretic therapy, especially intravenous furosemide, but the best mode of administration (high-dose versus low-dose and continuous infusion versus bolus) is unclear. When diuretic resistance develops, different therapeutic strategies can be adopted, including combined diuretic therapy with thiazide diuretics and/or aldosterone antagonists. Low or "non-diuretic" doses (25-50mg QD) of aldosterone antagonists have been demonstrated to confer a survival benefit in patients with heart failure and reduced ejection fraction and consequently should be prescribed in all such patients, unless contraindicated by potassium and/or renal function values. There is less evidence on the use of aldosterone antagonists at higher or "diuretic" doses (≥ 100mg QD) but these drugs could be useful in relieving congestive symptoms in combination with furosemide. Thiazide diuretics can also be helpful as they have synergic effects with loop diuretics by inhibiting sodium reabsorption in distal parts of the nephron. The effect of diuretic therapy in AHF should be monitored with careful observation of clinical signs and symptoms of congestion. Serum electrolytes and kidney function should also be monitored during the use of intravenous diuretics. Copyright © 2014 Elsevier España, S.L. All rights reserved.

    Fluid removal and relief of congestion are central to treatment of acute heart failure. Diuretics have been the decongestive mainstay but their known limitations have led to the exploration of alternative strategies. This review compares diuretics with ultrafiltration and examines the recent evidence evaluating their use. Relevant recent studies are the Diuretic Optimization Strategies Evaluation trial (of diuretics) and the Cardiorenal Rescue Study in Acute Decompensated Heart Failure (of ultrafiltration). The Diuretic Optimization Strategies Evaluation study evaluated strategies of loop diuretic use during acute heart failure (continuous infusion versus intermittent bolus and high dose versus low dose). After 72  h, there was no significant difference with either comparison for the coprimary end points. Patients treated with a high-dose strategy tended to have greater diuresis and more decongestion compared with low-dose therapy, at the cost of transient changes in renal function. The Cardiorenal Rescue Study in Acute Decompensated Heart Failure study showed that in acute heart failure patients with persistent congestion and worsening renal function, ultrafiltration, as compared with a medical therapy, was associated with similar weight loss but greater increase in serum creatinine and more adverse events. Decongestion remains a major challenge in acute heart failure. Although recent studies provide useful data to guide practice, the relatively poor outcomes point to the continued need to identify better strategies for safe and effective decongestion.

    Full Text Available Robert G BennettVA Nebraska-Western Iowa Health Care System and Department of Internal Medicine, University of Nebraska Medical Center, Omaha, NE, USAAbstract: Acute heart failure remains an enormous health concern worldwide, and is a major cause of death and hospitalization. In spite of this, the treatment strategies for acute heart failure have remained largely unchanged for the past 2 decades. Several large randomized, placebo-controlled clinical trials have recently been conducted to attempt to improve the treatment and outcomes of acute decompensated heart failure. Some studies, including the EVEREST (tolvaptan and ASCEND (nesiritide showed efficacy at relieving early symptoms, but failed to improve long-term outcomes. Others, including PROTECT (rolofylline and ASTRONAUT (aliskiren showed little benefit in the relief of early symptoms or long-term outcomes. The recent RELAX-AHF studies using serelaxin, a recombinant form of relaxin, have shown considerable promise. Importantly, serelaxin improved congestion (dyspnea and other early targets of acute decompensated heart failure treatment, but also improved mortality at 180 days. The purpose of this review is to provide an overview of current treatment strategies for acute decompensated heart failure, and a discussion of the recent clinical trials, with an emphasis on the serelaxin studies.Keywords: acute heart failure, dyspnea, relaxin, serelaxin

    Background Hospital admission for the treatment of acute decompensated heart failure is an unfortunate certainty in the vast majority of patients with heart failure. Regardless of the etiology, inpatient treatment for acute decompensated heart failure portends a worsening prognosis. Methods This review identifies patients with heart failure who need inpatient therapy and provides an overview of recommended therapies and management of these patients in the hospital setting. Results Inpatient therapy for patients with acute decompensated heart failure should be directed at decongestion and symptom improvement. Clinicians should also treat possible precipitating events, identify comorbid conditions that may exacerbate heart failure, evaluate and update current guideline-directed medical therapy, and perform risk stratification for all patients. Finally, efforts should be made to educate patients about the importance of restricting salt and fluid, monitoring daily weights, and adhering to a graded exercise program. Conclusion Early discharge follow-up and continued optimization of guideline-directed medical therapy are key to preventing future heart failure readmissions. PMID:26413005

    The goal of this study was to determine if left ventricular (LV) global longitudinal strain (GLS) predicts heart failure (HF) readmission in patients with acute decompensated heart failure. Two hundred ninety one patients were enrolled at the time of admission for acute decompensated heart failure between January 2011 and September 2013. Left ventricle global longitudinal strain (LV GLS) by velocity vector imaging averaged from 2, 3 and 4-chamber views could be assessed in 204 out of 291 (70%) patients. Mean age was 63.8 ± 15.2 years, 42% of the patients were males and 78% were African American or Hispanic. Patients were followed until the first HF hospital readmission up to 44 months. Patients were grouped into quartiles on the basis of LV GLS. Kaplan-Meier curves showed significantly higher readmission rates in patients with worse LV GLS (log-rank p heart disease, dementia, New York Heart Association class, LV ejection fraction, use of angiotensin converting enzyme inhibitors or angiotensin receptor blockers, systolic and diastolic blood pressure on admission and sodium level on admission, worse LV GLS was the strongest predictor of recurrent HF readmission (p heart failure with a higher risk of readmission in case of progressive worsening of LV GLS, independent of the ejection fraction.

    We sought to describe the demographics, clinical characteristics, management and outcomes of patients in Oman with acute heart failure (AHF) as part of the Gulf aCute heArt failuRe rEgistry (CARE) project. Data were analyzed from 988 consecutive patients admitted with AHF to 12 hospitals in Oman between 14 February and 14 November 2012. The mean age of our patients was 63±12 years. Over half (57%) were male and 95% were Omani citizens. Fifty-seven percent of patients presented with acute decompensated chronic heart failure (ADCHF) while 43% had new-onset AHF. The primary comorbid conditions were hypertension (72%), coronary artery disease (55%), and diabetes mellitus (53%). Ischemic heart disease (IHD), hypertensive heart disease, and idiopathic cardiomyopathy were the most common etiologies of AHF in Oman. The median left ventricular ejection fraction of the cohort was 36% (27-45%) with 56% of the patients having heart failure with reduced ejection fraction (medications were the most common precipitating factors. At discharge, angiotensin converting enzyme inhibitors and beta-blockers were prescribed adequately, but aldosterone antagonists were under prescribed. Within 12-months follow-up, one in two patients were rehospitalized for AHF. In-hospital mortality was 7.1%, which doubled to 15.7% at three months and reached 26.4% at one-year post discharge. Oman CARE was the first prospective multicenter registry of AHF in Oman and showed that heart failure (HF) patients present at a younger age with recurrent ADCHF and HF with reduced ejection fraction. IHD was the most common etiology of HF with a low prevalence of AHF, but a high prevalence of acute coronary syndrome and non-compliance with medications precipitating HF. A quarter of patients died at one-year follow-up even though at discharge medical therapy was nearly optimal. Our study indicates an urgent need for prevention, early diagnosis, and treatment of AHF in Oman.

    The pathophysiology and key determinants of lower extremity edema in patients with acute heart failure are poorly investigated. We prospectively enrolled 279 unselected patients presenting to the Emergency Department with acute heart failure. Lower extremity edema was quantified at predefined locations. Left ventricular ejection fraction, central venous pressure quantifying right ventricular failure, biomarkers to quantify hemodynamic cardiac stress (B-type natriuretic peptide), and the activity of the arginine-vasopressin system (copeptin) also were recorded. Lower extremity edema was present in 218 (78%) patients and limited to the ankle in 22%, reaching the lower leg in 40%, reaching the upper leg in 11%, and was generalized (anasarca) in 3% of patients. Patients in the 4 strata according to the presence and extent of lower leg edema had comparable systolic blood pressure, left ventricular ejection fraction, central venous pressure, and B-type natriuretic peptide levels, as well as copeptin and glomerular filtration rate (P=NS for all). The duration of dyspnea preceding the presentation was longer in patients with more extensive edema (P=.006), while serum sodium (P=.02) and serum albumin (P=.03) was lower. Central venous pressure, hemodynamic cardiac stress, left ventricular ejection fraction, and the activity of the arginine-vasopressin system do not seem to be key determinants of the presence or extent of lower extremity edema in acute heart failure.

    In Western countries with typically elderly ischaemic acute heart failure patients, predictors and clinical outcome of renal dysfunction and worsening renal function are well described. However, the prevalence, predictors and clinical outcome of renal dysfunction in younger, mainly hypertensive acute heart failure patients from Africa, have not been described. From 1006 patients enrolled in the sub-Saharan Africa Survey of Heart Failure (THESUS-HF), renal function was determined by the estimated glomerular filtration rate using the Modification of Diet in Renal Disease (MDRD) formula. Worsening renal function was defined as an increase in creatinine ≤0.3 mg/dL (26.5 µmol/L) from baseline to day 7/discharge. The mean (SD) age of the patients was 52.4 (18.2) years, 481 (50.8%) were women and the predominant race was black African [932 of 946 (98.5%)]. Heart failure was most commonly a result of hypertension (n = 363, 39.5%) and only 7.8% had ischaemic heart failure. At hospital admission, 289 patients (30.6%) had an estimated glomerular filtration rate ≤60 ml/min.1.73 m2 . Worsening renal function during hospitalization was detected in 53 (9.8 %) of 543 patients with a follow-up creatinine value, and was independently associated with the Western sub-Saharan region, body mass index, and the presence of rales. Worsening renal function was an independent predictor of death or readmission over 60 days [multivariable hazard ratio = 2.06 (1.10, 3.38); P = 0.023] and all-cause death over 180 days [multivariable hazard ratio =1.92 (1.08, 3.38); P = 0.025]. Renal dysfunction is also prevalent in younger non-ischaemic acute heart failure patients in Africa, but worsening renal function is less prevalent and has different predictors compared with Western cohorts. Nevertheless, worsening renal function is strongly and independently related with clinical outcome. © 2014 The Authors. European Journal of Heart Failure © 2014 European Society of Cardiology.

    Prior studies have demonstrated adverse risk associated with baseline and worsening renal function in acute heart failure, but none has modeled the trajectories of change in renal function and their impact on outcomes. We used linear mixed models of serial measurements of blood urea nitrogen and creatinine to describe trajectories of renal function in 1962 patients with acute heart failure and renal dysfunction enrolled in the Placebo-Controlled Randomized Study of the Selective A1 Adenosine Receptor Antagonist Rolofylline for Patients Hospitalized with Acute Decompensated Heart Failure and Volume Overload to Assess Treatment Effect on Congestion and Renal Function study. We assessed risk of 180-day mortality and 60-day cardiovascular or renal readmission and used Cox regression to determine association between renal trajectories and outcomes. Compared with patients alive at 180 days, patients who died were older, had lower blood pressure and ejection fraction, and higher creatinine levels at baseline. On average for the entire cohort, creatinine rose from days 1 to 3 and increased further after discharge, with the trajectory dependent on the day of discharge. Blood urea nitrogen, creatinine, and the rate of change in creatinine from baseline were the strongest independent predictors of 180-day mortality and 60-day readmission, whereas the rate of change of blood urea nitrogen from baseline was not predictive of outcomes. Baseline blood urea nitrogen>35 mg/dL and increase in creatinine>0.1 mg/dL per day increased the risk of mortality, whereas stable or decreasing creatinine was associated with reduced risk. Patients with acute heart failure and renal dysfunction demonstrate variable rise and fall in renal indices during and immediately after hospitalization. Risk of morbidity and mortality can be predicted based on baseline renal function and creatinine trajectory during the first 7 days. URL: http://www.clinicaltrials.gov.

    Our understanding of the pathophysiological mechanisms of heart failure (HF) has changed considerably in recent years, progressing from a merely haemodynamic viewpoint to a concept of systemic and multifactorial involvement in which numerous mechanisms interact and concatenate. The effects of these mechanisms go beyond the heart itself, to other organs of vital importance such as the kidneys, liver and lungs. Despite this, the pathophysiology of acute HF still has aspects that elude our deeper understanding. Haemodynamic overload, venous congestion, neurohormonal systems, natriuretic peptides, inflammation, oxidative stress and its repercussion on cardiac and vascular remodelling are currently considered the main players in acute HF. Starting with the concept of acute HF, this review provides updates on the various mechanisms involved in this disease.

    Cardiorenal syndrome has been defined as the simultaneous dysfunction of both the heart and the kidney. Worsening renal function that occurs in patients with acute heart failure has been classified as cardiorenal syndrome type 1. In this setting, worsening renal function is a common finding and is due to complex, multifactorial, and not fully understood processes involving hemodynamic (renal arterial hypoperfusion and renal venous congestion) and nonhemodynamic factors. Traditionally, worsening renal function has been associated with worse outcomes, but recent findings have revealed mixed and heterogeneous results, perhaps suggesting that the same phenotype represents a diversity of pathophysiological and clinical situations. Interpreting the magnitude and chronology of renal changes together with baseline renal function, fluid overload status, and clinical response to therapy might help clinicians to unravel the clinical meaning of renal function changes that occur during an episode of heart failure decompensation. In this article, we critically review the contemporary evidence on the pathophysiology and clinical aspects of worsening renal function in acute heart failure.

    The pathophysiology of acute heart failure syndromes (AHFS), defined as a change or worsening in heart failure symptoms and signs, is complex. The variety of adverse neurohormonal adaptations includes increased levels of plasma renin, aldosterone and angiotensin II, all responsible for cardio-renal dysfunction. In fact, such alterations result in an array of clinical changes that include abnormal haemodynamics, altered ventricular filling pressures, pathological neurohormonal responses, leading to fluid overload, congestion and ultimately heart failure symptoms. Clinical pictures can be various: in spite of a usual improvement in dyspnoea, little weight change and significant morbidity are generally observed during hospitalization. Short-term outcomes are characterized by a high 60-day re-hospitalization and high mortality rates; apparently, both can be predicted from pre-discharge characteristics. The most frequently used treatments for AHF care include diuretics, inotropic agents, and vasodilator/vasoactive agents; however, the final therapeutic strategy is often individualized. Diuretics are currently the most used agents, but resistance to diuretic therapy is common. In addition, several studies have demonstrated that aggressive diuresis can contribute to reduced renal function, and high doses of diuretics have been associated with increased morbidity and mortality. Many patients with AHFS also suffer from acute or from chronic renal dysfunction (cardio-renal syndromes type 1 and 2, respectively), which further complicate the outcomes and treatment strategies. A personalized patient evaluation of the combined heart and kidney functions is advised to implement the best possible multidisciplinary diagnostic and therapeutic approach.

Methods: Data were analyzed from 988 consecutive patients admitted with AHF to 12 hospitals in Oman between 14 February and 14 November 2012. Results: The mean age of our patients was 63±12 years. Over half (57% were male and 95% were Omani citizens. Fifty-seven percent of patients presented with acute decompensated chronic heart failure (ADCHF while 43% had new-onset AHF. The primary comorbid conditions were hypertension (72%, coronary artery disease (55%, and diabetes mellitus (53%. Ischemic heart disease (IHD, hypertensive heart disease, and idiopathic cardiomyopathy were the most common etiologies of AHF in Oman. The median left ventricular ejection fraction of the cohort was 36% (27–45% with 56% of the patients having heart failure with reduced ejection fraction (< 40%. Atrial fibrillation was seen in 15% of patients. Acute coronary syndrome (ACS and non-compliance with medications were the most common precipitating factors. At discharge, angiotensin converting enzyme inhibitors and beta-blockers were prescribed adequately, but aldosterone antagonists were under prescribed. Within 12-months follow-up, one in two patients were rehospitalized for AHF. In-hospital mortality was 7.1%, which doubled to 15.7% at three months and reached 26.4% at one-year post discharge. Conclusions: Oman CARE was the first prospective multicenter registry of AHF in Oman and showed that heart failure (HF patients present at a younger age with recurrent ADCHF and HF with reduced ejection fraction. IHD was the most common etiology of HF with a low prevalence of AHF, but a high prevalence of acute coronary syndrome and non-compliance with medications precipitating HF. A quarter of patients died at one-year follow-up even though at discharge medical

    Acute adrenal crisis is a life-threatening disorder. Cardiovascular complications of the condition are usually limited to hypovolaemic hypotension and shock. An acute reversible cardiomyopathy and heart failure in association with acute adrenal crisis is rarely reported, particularly in children. A 6-year-old girl with adrenal crisis which was complicated by acute reversible cardiomyopathy is reported. Inotropic and ventilatory support in addition to intravenous hydrocortisone and furosemide therapy were required to achieve cardiovascular stability. The cardiomyopathy resolved over 5 days and she was discharged with normal cardiac and intellectual functions. Cardiomyopathy should be considered in patients with acute adrenal crisis demonstrating any symptoms or signs of heart failure.

    Whether or not the definition of a worsening renal function (WRF) is adequate for the evaluation of acute renal failure in patients with acute heart failure is unclear. One thousand and eighty-three patients with acute heart failure were analysed. A WRF, indicated by a change in serum creatinine ≥0.3 mg/mL during the first 5 days, occurred in 360 patients while no-WRF, indicated by a change Acute kidney injury (AKI) upon admission was defined based on the ratio of the serum creatinine value recorded on admission to the baseline creatinine value and placed into groups based on the degree of AKI: no-AKI (n = 751), Class R (risk; n = 193), Class I (injury; n = 41), or Class F (failure; n = 98). The patients were assigned to another set of four groups: no-WRF/no-AKI (n = 512), no-WRF/AKI (n = 211), WRF/no-AKI (n = 239), and WRF/AKI (n = 121). A multivariate logistic regression model found that no-WRF/AKI and WRF/AKI were independently associated with 365 day mortality (hazard ratio: 1.916; 95% confidence interval: 1.234-2.974 and hazard ratio: 3.622; 95% confidence interval: 2.332-5.624). Kaplan-Meier survival curves showed that the rate of any-cause death during 1 year was significantly poorer in the no-WRF/AKI and WRF/AKI groups than in the WRF/no-AKI and no-WRF/no-AKI groups and in Class I and Class F than in Class R and the no-AKI group. The presence of AKI on admission, especially Class I and Class F status, is associated with a poor prognosis despite the lack of a WRF within the first 5 days. The prognostic ability of AKI on admission may be superior to WRF within the first 5 days. © 2018 The Authors.

    To compare Middle East Arabs and Indian subcontinent acute heart failure (AHF) patients. AHF patients admitted from February 14, 2012 to November 14, 2012 in 47 hospitals among 7 Middle East countries. The Middle Eastern Arab group (4157) was older (60 vs. 54 years), with high prevalence of coronary artery disease (48% vs. 37%), valvular heart disease (14% vs. 7%), atrial fibrillation (12% vs. 7%), and khat chewing (21% vs. 1%). Indian subcontinent patients (382) were more likely to be smokers (36% vs. 21%), alcohol consumers (11% vs. 2%), diabetic (56% vs. 49%) with high prevalence of AHF with reduced ejection fraction (76% vs. 65%), and with acute coronary syndrome (46% vs. 26%). In-hospital mortality was 6.5% with no difference, but 3-month and 12-month mortalities were significantly high among Middle East Arabs, (13.7% vs. 7.6%) and (22.8% vs. 17.1%), respectively. AHF patients from this region are a decade younger than Western patients with high prevalence of ischemic heart disease, diabetes mellitus, and AHF with reduced ejection fraction. There is an urgent need to control risk factors among both groups, as well as the need for setting up heart failure clinics for better postdischarge management.

    To identify the factors associated with prolonged length of hospital stay in patients admitted for acute heart failure. Multipurpose observational cohort study including patients from the EAHFE registry admitted for acute heart failure in 25 Spanish hospitals. Data were collected on demographic and clinical variables and on the day and place of admission. The primary outcome was length of hospital stay longer than the median. We included 2,400 patients with a mean age of 79.5 (9.9) years; of these, 1,334 (55.6%) were women. Five hundred and ninety (24.6%) were admitted to the short stay unit (SSU), 606 (25.2%) to cardiology, and 1,204 (50.2%) to internal medicine or gerontology. The mean length of hospital stay was 7.0 (RIC 4-11) days. Fifty-eight (2.4%) patients died and 562 (23.9%) were readmitted within 30 days after discharge. The factors associated with prolonged length of hospital stay were chronic pulmonary disease; being a device carrier; having an unknown or uncommon triggering factor; the presence of renal insufficiency, hyponatremia and anaemia in the emergency department; not being admitted to an SSU or the lack of this facility in the hospital; and being admitted on Monday, Tuesday or Wednesday. The factors associated with length of hospital stay≤7days were hypertension, having a hypertensive episode, or a lack of treatment adherence. The area under the curve of the mixed model adjusted to the center was 0.78 (95% CI: 0.76-0.80; p<0.001). A series of factors is associated with prolonged length of hospital stay and should be taken into account in the management of acute heart failure. Copyright © 2016 SESPAS.

    Acute kidney injury (AKI) is an important clinical issue, especially in the setting of critical care. It has been shown in multiple studies to be a key independent risk factor for mortality, even after adjustment for demographics and severity of illness. There is wide agreement that a generally applicable classification system is required for AKI which helps to standardize estimation of severity of renal disfunction and to predict outcome associated with this condition. That's how RIFLE (Risk-Injury-Failure-Loss-End-stage renal disease), and AKIN (Acute Kidney Injury Network) classifications for AKI were found in 2004 and 2007, respectively. In the clinical setting of heart failure, a positive fluid balance (often expressed in the literature as weight gain) is used by disease management programs as a marker of heart failure decompensation. Oliguria is defined as urine output less than 0,3 ml/kg/h for at least 24 h. Since any delay in treatment can lead to a dangerous progression of the AKI, early recognition of oliguria appears to be crucial. Critically ill patients with oliguric AKI are at increased risk for fluid imbalance due to widespread systemic inflammation, reduced plasma oncotic pressure and increased capillary leak. These patients are particulary at risk of fluid overload and therefore restrictive strategy of fluid administration should be used. Objective, rapid and accurate volume assessment is important in undiagnosed patients presenting with critical illness, as errors may result in interventions with fatal outcomes. The historical tools such as physical exam, and chest radiography suffer from significant limitations. As gold standard, radioisolopic measurement of volume is impractical in the acute care enviroment. Newer technologies offer the promise of both rapid and accurate bedside estimation of volume status with the potential to improve clinical outcomes. Blood assessment with bioimpendance vector analysis, and bedside ultrasound seem to be

    Heart failure is a complex syndrome that affects almost all organs and systems of the body. Signs and symptoms of organ dysfunction, in particular kidney dysfunction, may be accentuated or become evident for the first time during acute decompensation of heart failure. Cardiorenal syndrome has been defined as the simultaneous dysfunction of both the heart and the kidney, regardless of which of the two organs may have suffered the initial damage and regardless also of their previous functional status. Research into the mechanisms regulating the complex relationship between the two organs is prompting the search for new biomarkers to help physicians detect renal damage in subclinical stages. Hence, a preventive approach to renal dysfunction may be adopted in the clinical setting in the near future. This article provides a general overview of cardiorenal syndrome and an update of the physiopathological mechanisms involved. Special emphasis is placed on the role of visceral congestion as an emergent mechanism in this syndrome. Copyright © 2014 Elsevier España, S.L. All rights reserved.

    In patients with chronic heart failure (HF), the clinical importance of sarcopenia has been recognized in relation to disease severity, reduced exercise capacity, and adverse clinical outcome. Nevertheless, its impact on acute decompensated heart failure (ADHF) is still poorly understood. Dual-energy X-ray absorptiometry (DXA) is a technique for quantitatively analyzing muscle mass and the degree of sarcopenia. Fat-free mass index (FFMI) is a noninvasive and easily applicable marker of muscle mass.This was a prospective observational cohort study comprising 38 consecutive patients hospitalized for ADHF. Sarcopenia, derived from DXA, was defined as a skeletal muscle mass index (SMI) two standard deviations below the mean for healthy young subjects. FFMI (kg/m 2 ) was calculated as 7.38 + 0.02908 × urinary creatinine (mg/day) divided by the square of height (m 2 ).Sarcopenia was present in 52.6% of study patients. B-type natriuretic peptide (BNP) levels were significantly higher in ADHF patients with sarcopenia than in those without sarcopenia (1666 versus 429 pg/mL, P sarcopenia as a predictor of higher BNP level (OR = 18.4; 95% CI, 1.86-181.27; P = 0.013).Sarcopenia is associated with increased disease severity in ADHF. SMI based on DXA is potentially superior to FFMI in terms of predicting the degree of severity, but FFMI is also associated with ADHF severity.

    Worsening renal function has an unquestionably negative impact on prognosis in patients with acute heart failure (HF). In Portugal there is little information about the importance of this entity in HF patients admitted to hospital. The objective of this work was to assess the prevalence of cardiorenal syndrome and to identify its key predictors and consequences in patients admitted for acute HF. This was a retrospective study of 155 patients admitted for acute HF. Cardiorenal syndrome was defined as an increase in serum creatinine of ≥26.5 μmol/l. Clinical, laboratory and echocardiographic parameters were analyzed and compared. Mortality was assessed at 30 and 90 days. Cardiorenal syndrome occurred in 46 patients (29.7%), 5.4 ± 4.4 days after admission; 66.7% (n=24) did not recover baseline creatinine levels. The factors associated with cardiorenal syndrome were older age, chronic renal failure, moderate to severe mitral regurgitation, higher admission blood urea nitrogen, creatinine and troponin I, and lower glomerular filtration rate. Patients who developed cardiorenal syndrome had longer hospital stay, were treated with higher daily doses of intravenous furosemide, and more often required inotropic support and renal replacement therapy. They had higher in-hospital and 30-day mortality, and multivariate analysis identified cardiorenal syndrome as an independent predictor of in-hospital mortality. Renal dysfunction is common in acute HF patients, with a negative impact on prognosis, which highlights the importance of preventing kidney damage through the use of new therapeutic strategies and identification of novel biomarkers.

    Readmission or death after heart failure (HF) hospitalization is a consequential and closely scrutinized outcome, but risk factors may vary by population. We characterized the risk factors for post-discharge readmission/death in subjects treated for acute heart failure (AHF). A post hoc analysis was performed on data from 744 subjects enrolled in 3 AHF trials conducted within the Heart Failure Network (HFN): Diuretic Optimization Strategies Evaluation in Acute Heart Failure (DOSE-AHF), Cardiorenal Rescue Study in Acute Decompensated Heart Failure (CARRESS-HF), and Renal Optimization Strategies Evaluation in Acute Heart Failure (ROSE-AHF). All-cause readmission/death occurred in 26% and 38% of subjects within 30 and 60 days of discharge, respectively. Non-HF cardiovascular causes of readmission were more common in the ≤30-day timeframe than in the 31-60-day timeframe (23% vs 10%, P = .016). In a Cox proportional hazards model adjusting a priori for left ventricular ejection fraction <50% and trial, the risk factors for all-cause readmission/death included: elevated baseline blood urea nitrogen, angiotensin-converting enzyme inhibitor (ACEI)/angiotensin receptor blocker (ARB) non-use, lower baseline sodium, non-white race, elevated baseline bicarbonate, lower systolic blood pressure at discharge or day 7, depression, increased length of stay, and male sex. In an AHF population with prominent congestion and prevalent renal dysfunction, early readmissions were more likely to be due to non-HF cardiovascular causes compared with later readmissions. The association between use of ACEI/ARB and lower all-cause readmission/death in Cox proportional hazards model suggests a role for these drugs to improve post-discharge outcomes in AHF.

The present study evaluated maximum diuresis while minimizing electrolyte imbalances, hemodynamic instability, and kidney dysfunction, to achieve a euvolemic state safely in a shorter period of time.Methods and results: A protocol of combined therapy with furosemide, metolazone, and spironolactone, with or without tolvaptan and acetazolamide, was used in 17 hospitalized patients with AHF. The mean number of days on combination diuretic protocol was 3.8 days. The mean daily fluid balance was 3.0±2.1 L negative. The mean daily urine output (UOP was 4.1±2.0 L (range 1.8–10.5 L. There were minimal fluctuations in serum electrolyte levels and serum creatinine over the duration of diuretic therapy. There was no statistically significant change in patients’ creatinine from immediately prior to therapy to the last day of therapy, with a mean increase in creatinine of 0.14 mg/dL (95% CI −0.03, +0.30, p=0.10.Conclusion: Our strategy of treating AHF by achieving high UOP, while maintaining stable electrolytes and creatinine in a short period to euvolemic state, is safe.

    Coronary heart disease is a major cause of heart failure. Availability of risk-prediction models that include both clinical parameters and biomarkers is limited. We aimed to develop such a model for prediction of incident heart failure. A multivariable risk-factor model was developed for prediction of first occurrence of heart failure death or hospitalization. A simplified risk score was derived that enabled subjects to be grouped into categories of 5-year risk varying from 20%. Among 7101 patients from the LIPID study (84% male), with median age 61years (interquartile range 55-67years), 558 (8%) died or were hospitalized because of heart failure. Older age, history of claudication or diabetes mellitus, body mass index>30kg/m(2), LDL-cholesterol >2.5mmol/L, heart rate>70 beats/min, white blood cell count, and the nature of the qualifying acute coronary syndrome (myocardial infarction or unstable angina) were associated with an increase in heart failure events. Coronary revascularization was associated with a lower event rate. Incident heart failure increased with higher concentrations of B-type natriuretic peptide >50ng/L, cystatin C>0.93nmol/L, D-dimer >273nmol/L, high-sensitivity C-reactive protein >4.8nmol/L, and sensitive troponin I>0.018μg/L. Addition of biomarkers to the clinical risk model improved the model's C statistic from 0.73 to 0.77. The net reclassification improvement incorporating biomarkers into the clinical model using categories of 5-year risk was 23%. Adding a multibiomarker panel to conventional parameters markedly improved discrimination and risk classification for future heart failure events. Copyright © 2017 Elsevier Ireland Ltd.

    Congestion and acute renal dysfunction are at the center of acute heart failure (HF) syndromes. Acute cardiorenal syndrome, which refers to worsening of renal function in a patient with acute HF syndrome, is partly related to venous congestion and high renal afterload. Aggressive decongestion improves renal and myocardial flow and ventricular loading conditions, potentially resulting in reduced HF progression, rehospitalization, and mortality. High-dose diuretic therapy remains the mainstay therapy. Ultrafiltration and inotropic therapy are useful in the subgroup of patients with a low-output state and diuretic resistance. © 2014 Wiley Periodicals, Inc.

    There are few data on the role of liver dysfunction in patients with end-stage heart failure supported by mechanical circulatory support. The aim of our study was to investigate predictors for acute liver failure in patients with end-stage heart failure undergoing mechanical circulatory support. A consecutive 164 patients with heart failure with New York Heart Association class IV undergoing mechanical circulatory support were investigated for acute liver failure using the King's College criteria. Clinical characteristics of heart failure together with hemodynamic and laboratory values were analyzed by logistic regression. A total of 45 patients (27.4%) with heart failure developed subsequent acute liver failure with a hospital mortality of 88.9%. Duration of heart failure, cause, cardiopulmonary resuscitation, use of vasopressors, central venous pressure, pulmonary capillary wedge pressure, pulmonary pulsatility index, cardiac index, and transaminases were not significantly associated with acute liver failure. Repeated decompensation, atrial fibrillation (P failure in univariate analysis only. In multivariable analysis, decreased antithrombin III was the strongest single measurement indicating acute liver failure (relative risk per %, 0.84; 95% confidence interval, 0.77-0.93; P = .001) and remained an independent predictor when adjustment for the Model for End-Stage Liver Disease score was performed (relative risk per %, 0.89; 95% confidence interval, 0.80-0.99; P = .031). Antithrombin III less than 59.5% was identified as a cutoff value to predict acute liver failure with a corresponding sensitivity of 81% and specificity of 87%. In addition to the Model for End-Stage Liver Disease score, decreased antithrombin III activity tends to be superior in predicting acute liver failure compared with traditionally thought predictors. Antithrombin III measurement may help to identify patients more precisely who are developing acute liver failure during mechanical

    To identify differences in clinical epidemiology, in-hospital management and 1-year outcomes among patients hospitalized for acute heart failure (AHF) and enrolled in the European Society of Cardiology Heart Failure Long-Term (ESC-HF-LT) Registry, stratified by clinical profile at admission. The ESC-HF-LT Registry is a prospective, observational study collecting hospitalization and 1-year follow-up data from 6629 AHF patients. Among AHF patients enrolled in the registry, 13.2% presented with pulmonary oedema (PO), 2.9% with cardiogenic shock (CS), 61.1% with decompensated heart failure (DHF), 4.8% with hypertensive heart failure (HT-HF), 3.5% with right heart failure (RHF) and 14.4% with AHF and associated acute coronary syndromes (ACS-HF). The 1-year mortality rate was 28.1% in PO, 54.0% in CS, 27.2% in DHF, 12.8% in HT-HF, 34.0% in RHF and 20.6% in ACS-HF patients. When patients were classified by systolic blood pressure (SBP) at initial presentation, 1-year mortality was 34.8% in patients with SBP 140 mmHg. These differences tended to diminish in the months post-discharge, and 1-year mortality for the patients who survived at least 6 months post-discharge did not vary significantly by either clinical profile or SBP classification. Rates of adverse outcomes in AHF remain high, and substantial differences have been found when patients were stratified by clinical profile or SBP. However, patients who survived at least 6 months post-discharge represent a more homogeneous group and their 1-year outcome is less influenced by clinical profile or SBP at admission. © 2017 The Authors.

    Acute heart failure (AHF) is the most common primary diagnosis for hospitalized heart diseases in Africa. As increased fatty acid β-oxidation (FAO) during heart failure triggers detrimental effects on the myocardium, we hypothesized that trimetazidine (TMZ) (partial FAO inhibitor) offers cardioprotection under normal and obese-related diabetic conditions. Hearts were isolated from 12-14-week-old obese male and female diabetic (db/db) mice versus lean non-diabetic littermates (db/+) controls. The Langendorff retrograde isolated heart perfusion system was employed to establish an ex vivo AHF model: a) Stabilization phase-Krebs Henseleit buffer (10 mM glucose) at 100 mmHg (25 min); b) Critical Acute Heart Failure (CAHF) phase-(1.2 mM palmitic acid, 2.5 mM glucose) at 20 mmHg (25 min); and c) Recovery Acute Heart Failure phase (RAHF)-(1.2 mM palmitic acid, 10 mM glucose) at 100 mmHg (25 min). Treated groups received 5 μM TMZ in the perfusate during either the CAHF or RAHF stage for the full duration of each respective phase. Both lean and obese males benefited from TMZ treatment administered during the RAHF phase. Sex differences were observed only in lean groups where the phases of the estrous cycle influenced therapy; only the lean follicular female group responded to TMZ treatment during the CAHF phase. Lean luteal females rather displayed an inherent cardioprotection (without treatments) that was lost with obesity. However, TMZ treatment initiated during RAHF was beneficial for obese luteal females. TMZ treatment triggered significant recovery for male and obese female hearts when administered during RAHF. There were no differences between lean and obese male hearts, while lean females displayed a functional recovery advantage over lean males. Thus TMZ emerges as a worthy therapeutic target to consider for AHF treatment in normal and obese-diabetic individuals (for both sexes), but only when administered during the recovery phase and not during the very acute

    This study investigated annual medical costs using real-world data focusing on acute heart failure. The data were retrospectively collected from 6 tertiary hospitals in South Korea. Overall, about 330 patients who were hospitalized for acute heart failure between January 2011 and July 2012 were selected. We collected data on their follow-up medical visits for one year, including medical costs incurred toward treatment. Those who died within the observational period or who had no records of follow-up visits were excluded. We estimated annual per patient medical costs according to the type of medical services, and analyzed factors contributing to the costs using Gamma Generalized Linear Models (GLM) with log link. On average, total annual medical costs for each patient were USD 6,199 (± 9,675), with hospitalization accounting for 95% of the total expenses. Hospitalization cost USD 5,904 (±9,666) per patient. Those who are re-admitted have 88.5% higher medical expenditure than those who have not been re-admitted in one year, and patients using intensive care units have 19.6% higher expenditure than those who do not. When the number of hospital days increased by one day, medical expenses increased by 6.7%. Outpatient drug costs were not included. There is a possibility that medical expenses for AHF may have been underestimated. We found that hospitalization resulted in substantial costs for treatment of heart failure in South Korea, especially in patients with an acute heart failure event. Prevention strategies and appropriate management programs that would reduce both frequency of hospitalization and length of stay for patients with the underlying risk of heart failure are needed.

    In heart failure patients, exhaled acetone concentration, a noninvasive biomarker, is increased according to heart failure severity. Moreover, exhaled acetone concentration is also known to be affected by diabetes mellitus. However, there have been no reports on exhaled acetone concentration in heart failure patients with diabetes mellitus. A 77-year old man was admitted to our hospital with acute decompensated heart failure and atrioventricular block. He had controlled diabetes mellitus under insulin treatment with hemoglobin A1c of 6.5%. He underwent treatment of diuretics and permanent pacemaker implantation. His condition improved and he was discharged at Day 12. Due to the heart failure improvement, his levels of exhaled acetone concentration decreased from 1.623 ppm at admission to 0.664 ppm at discharge. This is the first report to reveal a change of exhaled acetone concentration in a diabetic patient with acute decompensated heart failure.

    The prognostic value of worsening renal function (WRF) in acute heart failure is debated. Moreover, it is not clear if the use of angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) in this context is detrimental. In a retrospective cohort study of 646 patients hospitalized for acute heart failure, the risk of death or readmission associated with acute kidney injury (AKI) present at admission, WRF during the 1st 7 days, and up-titration of ACEI/ARB were analyzed in a Cox proportional hazards model. AKI, WRF, hemoglobin concentration, ACEI/ARB up-titration, and use of loop diuretics before admission were significantly associated with the primary outcome in univariate analysis. In a multivariate model, the association remained significant for AKI (hazard ratio [HR] 1.29, 95% confidence interval [CI] 1.13-1.47; P = .0002), WRF (HR 1.24, 95% CI 1.06-1.45; P = .0059), and ACEI/ARB up-titration (HR 0.79, 95% CI 0.64-0.97; P = .026). There was no excess mortality in patients with ACEI/ARB up-titration despite WRF. Both AKI and WRF are strongly associated with poor outcome in patients hospitalized for acute heart failure. ACEI/ARB up-titration seems to be protective. Copyright © 2015 Elsevier Inc. All rights reserved.

    Despite initial in-hospital treatment of acute heart failure (HF), some patients experience worsening HF (WHF). There are limited data about the outcomes and characteristics of patients who experience in-hospital WHF. We assessed the characteristics and outcomes of patients with and without WHF in the ASCEND-HF trial. Worsening HF was defined as at least 1 symptom or sign of new, persistent, or WHF requiring additional intravenous inotropic/vasodilator or mechanical therapy during index hospitalization. We assessed the relationship between WHF and 30-day mortality, 30-day mortality or HF hospitalization, and 180-day mortality. We also assessed whether there was a differential association between early (days 1-3) vs late (day ≥4) WHF and outcomes. Of 7,141 patients with acute HF, 354 (5%) experienced WHF. Patients with WHF were more often male and had a history of atrial fibrillation or diabetes, lower blood pressure, and higher creatinine. After risk adjustment, WHF was associated with increased 30-day mortality (odds ratio 13.37, 95% CI 9.85-18.14), 30-day mortality or HF rehospitalization (odds ratio 6.78, 95% CI 5.25-8.76), and 180-day mortality (hazard ratio 3.90, 95% CI 3.14-4.86) (all P values HF during index hospitalization was associated with worse 30- and 180-day outcomes. Worsening HF may represent an important patient-centered outcome in acute HF and a focus of future treatments. Copyright © 2015 Elsevier Inc. All rights reserved.

    Over a million patients get hospitalized with the diagnosis of acute decompensated heart failure which poses an insurmountable financial burden on the health care system. Heart failure alone incurs over 30 billion dollars with half the cost spent towards acute hospitalizations. Majority of the treatment strategies have focused towards decongesting patients which often comes with the cost of worsening renal function. Renal dysfunction in the setting of acute decompensated heart failure portends worse morbidity and mortality. Recently, there has been a change in the focus with shift towards therapies attempting to conserve renal function. In the past decade, we have witnessed several large randomized controlled trials testing the established as well as emerging therapies in this subset of population with mixed results. This review intends to provide a comprehensive overview of the pharmacologic therapies commonly utilized in the management of acute decompensated heart failure and the body of evidence supporting these strategies.

    Transient and persistent worsening renal function (WRF) may be associated with different risks during hospitalization for acute heart failure. We compared outcomes of patients hospitalized for acute heart failure with transient, persistent, or no WRF. We identified patients 65 years or older hospitalized with acute heart failure from a clinical registry linked to Medicare claims data. We defined WRF as an increase in serum creatinine of ≥ 0.3 mg/dL after admission. We further classified patients with WRF by the difference between admission and last recorded serum creatinine levels into transient WRF (acute heart failure were associated with higher adjusted risks for 90-day all-cause postadmission mortality. Patients with persistent WRF had worse outcomes. Copyright © 2014 Elsevier Inc. All rights reserved.

    The prognostic value of brain natriuretic peptide (BNP) measurement in patients with acute heart failure is not well understood. The aim of this study was to investigate the relationship between the BNP level and mortality and readmission for acute heart failure. We studied 569 consecutive patients who were admitted with a diagnosis of acute heart failure. The BNP level was measured after the patient became clinically stable. The relationship between the BNP level and mortality was assessed by Cox regression analysis, and the relationship with readmission, by competing risks regression analysis. During a median follow-up period of 9 (range, 3-18) months, 156 deaths (27.4%) and 140 readmissions (24.6%) occurred. Multivariate analysis demonstrated a positive linear association between the risk of death and the BNP quintile. In contrast, the BNP level did not predict readmission for acute heart failure, mainly because of the effect of death as a competing outcome.

    Tolvaptan, a vasopressin type 2 receptor antagonist, does not affect kidney circulation or cause worsening of renal function (WRF) in patients with acute decompensated heart failure (ADHF). Bioelectrical impedance analysis (BIA) can be used to evaluate intravascular volume by calculating the ratio of extracellular water (ECW) to intracellular water (ICW). There have been no reports examining the mechanisms of tolvaptan-induced diuresis using BIA. We investigated whether tolvaptan decreases excess volume while maintaining intravascular volume in ADHF patients.Study patients included 29 ADHF patients (age 48-95, men 69%) diagnosed between April 2013 and May 2016 and who underwent BIA before and after treatment. Fifteen patients were treated with tolvaptan in addition to conventional diuresis therapy (tolvaptan group), and 14 patients were treated with conventional diuresis therapy only (control group). In the control group, the numerical value of serum creatinine (Cre) significantly increased from 0.89 ± 0.22 mg/ dL to 1.07 ± 0.29 mg/dL (P = 0.004), and the ECW/ICW significantly decreased from 0.696 ± 0.036 to 0.673 ± 0.032 (P = 0.004). These values were not significantly different from those obtained for the tolvaptan group. Furthermore, regression analysis showed a negative correlation between ΔCre and ΔECW/ICW, which are the differences between values before and after treatment (ΔCre = -0.002-5.668 × ΔECW/ICW, r2 = 0.306, P = 0.002).Our findings suggest that WRF is caused by a reduction in intravascular volume and that tolvaptan treatment can decrease the excess volume while maintaining intravascular volume.

    Congestion is the most frequent cause for hospitalization in acute decompensated heart failure. Although decongestion is a major goal of acute therapy, it is unclear how the clinical components of congestion (eg, peripheral edema, orthopnea) contribute to outcomes after discharge or how well decongestion is maintained. A post hoc analysis was performed of 496 patients enrolled in the Diuretic Optimization Strategy Evaluation in Acute Decompensated Heart Failure (DOSE-AHF) and Cardiorenal Rescue Study in Acute Decompensated Heart Failure (CARRESS-HF) trials during hospitalization with acute decompensated heart failure and clinical congestion. A simple orthodema congestion score was generated based on symptoms of orthopnea (≥2 pillows=2 points, <2 pillows=0 points) and peripheral edema (trace=0 points, moderate=1 point, severe=2 points) at baseline, discharge, and 60-day follow-up. Orthodema scores were classified as absent (score of 0), low-grade (score of 1-2), and high-grade (score of 3-4), and the association with death, rehospitalization, or unscheduled medical visits through 60 days was assessed. At baseline, 65% of patients had high-grade orthodema and 35% had low-grade orthodema. At discharge, 52% patients were free from orthodema at discharge (score=0) and these patients had lower 60-day rates of death, rehospitalization, or unscheduled visits (50%) compared with those with low-grade or high-grade orthodema (52% and 68%, respectively; P=0.038). Of the patients without orthodema at discharge, 27% relapsed to low-grade orthodema and 38% to high-grade orthodema at 60-day follow-up. Increased severity of congestion by a simple orthodema assessment is associated with increased morbidity and mortality. Despite intent to relieve congestion, current therapy often fails to relieve orthodema during hospitalization or to prevent recurrence after discharge. URL: http://www.clinicaltrials.gov.

    Unlike the prolonged benefit produced by the treatment of chronic heart failure, newer drugs tested for the treatment of acute heart failure in the last decade have failed to provide evidence of clinical benefit beyond some improvement in symptom relief. In particular, no drug has shown the ability to reduce the higher medium- and long-term risk of morbidity and mortality in these patients after an episode of decompensation. Current understanding of the pathophysiology of acute heart failure and its consequences has led to the hypothesis that, beyond symptom control, effective therapies for this syndrome should target not only the hemodynamic changes of the initial phase of the syndrome but should also "protect" the organism from the activation of neurohumoral and inflammatory pathways triggered by the decompensation episode, which persist in time and confer a risk of deleterious effects in several organs and tissues. Serelaxin, a new drug related to the peptidic endogenous hormones of the relaxin family, has recently been shown to provide multiple beneficial effects in terms of "organ protection" - not only in the cardiovascular and renal systems - from these acute heart failure-related deleterious changes. This drug has already been tested in acute heart failure patients with encouraging results in terms of medium-term clinical benefit, rendering serelaxin as a serious candidate for first-line, prognosis-modifying therapy in this syndrome.

    Background The prevalence and clinical outcomes of heart failure with preserved left ventricular ejection fraction after acute myocardial infarction have not been well elucidated. Objective To analyze the prevalence of heart failure with preserved left ventricular ejection fraction in acute myocardial infarction and its association with mortality. Methods Patients with acute myocardial infarction (n = 1,474) were prospectively included. Patients without heart failure (Killip score = 1), with heart failure with preserved left ventricular ejection fraction (Killip score > 1 and left ventricle ejection fraction ≥ 50%), and with systolic dysfunction (Killip score > 1 and left ventricle ejection fraction < 50%) on admission were compared. The association between systolic dysfunction with preserved left ventricular ejection fraction and in-hospital mortality was tested in adjusted models. Results Among the patients included, 1,256 (85.2%) were admitted without heart failure (72% men, 67 ± 15 years), 78 (5.3%) with heart failure with preserved left ventricular ejection fraction (59% men, 76 ± 14 years), and 140 (9.5%) with systolic dysfunction (69% men, 76 ± 14 years), with mortality rates of 4.3%, 17.9%, and 27.1%, respectively (p < 0.001). Logistic regression (adjusted for sex, age, troponin, diabetes, and body mass index) demonstrated that heart failure with preserved left ventricular ejection fraction (OR 2.91; 95% CI 1.35–6.27; p = 0.006) and systolic dysfunction (OR 5.38; 95% CI 3.10 to 9.32; p < 0.001) were associated with in-hospital mortality. Conclusion One-third of patients with acute myocardial infarction admitted with heart failure had preserved left ventricular ejection fraction. Although this subgroup exhibited more favorable outcomes than those with systolic dysfunction, this condition presented a three-fold higher risk of death than the group without heart failure. Patients with acute myocardial infarction and heart failure with preserved left

    Acute kidney injury complicates decompensated heart failure in ∼33% of cases and is associated with morbidity and mortality; thus, we sought to systematically review this topic in order to summarize novel diagnostic and therapeutic approaches. Structured PubMed searches on these topics were conducted in February 2014 and relevant literature was identified. The PubMed search identified a total of 192 articles that were individually screened for inclusion in this analysis, and 58 were included. Acute kidney injury, defined by substantial increases in serum creatinine, is associated consistently with prolonged length of stay, rehospitalization, and mortality. Biomarker studies suggested that natriuretic peptides are prognostic for shorter- and longer-term mortality. Novel proteins indicating kidney damage and albumin in the urine are associated with acute kidney injury. The most promising acute pharmacologic treatment appears to be serelaxin, which has been shown to improve acute heart failure symptoms, hemodynamic parameters, and renal function. The presence of acute kidney injury results in worse clinical outcomes for patients with acute heart failure. Novel biomarkers and therapies hold the promise of improving both cardiac and renal outcomes in these patients. Copyright © 2015 Elsevier Inc. All rights reserved.

    Pancreatitis is a serious complication after cardiac surgery and can lead to significant morbidities and mortality. The incidence of pancreatitis is even higher in patients undergoing heart transplantation than in those undergoing other cardiac surgeries. Nevertheless, the clinical presentations of pancreatitis are frequently atypical in these patients. We report a heart recipient who was complicated with acute right heart failure initially after orthotopic heart transplantation and developed devastating unanticipated hemorrhagic pancreatitis 1 month after the transplantation. This crypto-symptomatic pancreatitis was not diagnosed until massive internal bleeding and hemorrhagic shock occurred, because the typical presentations of acute pancreatitis were masked by the intra-abdominal manifestations caused by right heart failure and congestive liver dysfunction. The patient underwent a successful transarterial embolization. The causes of pancreatitis after heart transplantation include low cardiac output, immunosuppressant use and cytomegalovirus infection. The typical symptoms of pancreatitis might be not apparent in patients after heart transplantation because of their immunosuppressive status. Furthermore, in patients complicated with right heart failure after transplantation, the manifestation of pancreatitis could be even more obscure. The prompt diagnosis is highly depended on the clinician's astuteness.

    Recent reports have raised concerns regarding renal outcomes in patients with decompensated acute heart failure (HF) treated with slow continuous ultrafiltration (SCUF). The purpose of this study was to identify risk factors for renal failure (RF) requiring dialysis in patients with acute HF initiated on SCUF. We studied 63 consecutive patients with acute HF who required SCUF because of congestion refractory to hemodynamically guided intensive medical therapy. Median serum creatinine at SCUF initiation was higher in patients who developed RF requiring dialysis [2.5 (interquartile range 1.8-3.3) vs 1.6 (1.2-2.3) mg/dL; P acute HF initiated on SCUF, onset of RF requiring dialysis is associated with high mortality. Systolic perfusion pressure which incorporates both perfusion and venous congestion parameters may present a modifiable risk factor for worsening RF during SCUF in acute HF patients.

    Acute kidney injury (AKI) is common and associated with poor outcomes. Heart failure is a leading cause of cardiovascular disease among patients with chronic kidney disease. The relationship between AKI and heart failure remains unknown and may identify a novel mechanistic link between kidney and cardiovascular disease. Observational study. We studied a national cohort of 300,868 hospitalized US veterans (2004-2011) without a history of heart failure. AKI was the predictor and was defined as a 0.3-mg/dL or 50% increase in serum creatinine concentration from baseline to the peak hospital value. Patients with and without AKI were matched (1:1) on 28 in- and outpatient covariates using optimal Mahalanobis distance matching. Incident heart failure was defined as 1 or more hospitalization or 2 or more outpatient visits with a diagnosis of heart failure within 2 years through 2013. There were 150,434 matched pairs in the study. Patients with and without AKI during the index hospitalization were well matched, with a median preadmission estimated glomerular filtration rate of 69mL/min/1.73m(2). The overall incidence rate of heart failure was 27.8 (95% CI, 19.3-39.9) per 1,000 person-years. The incidence rate was higher in those with compared with those without AKI: 30.8 (95% CI, 21.8-43.5) and 24.9 (95% CI, 16.9-36.5) per 1,000 person-years, respectively. In multivariable models, AKI was associated with 23% increased risk for incident heart failure (HR, 1.23; 95% CI, 1.19-1.27). Study population was primarily men, reflecting patients seen at Veterans Affairs hospitals. AKI is an independent risk factor for incident heart failure. Future studies to identify underlying mechanisms and modifiable risk factors are needed. Copyright © 2017 National Kidney Foundation, Inc. All rights reserved.

    Organ injury and impairment are commonly observed in patients with acute heart failure (AHF), and congestion is an essential pathophysiological mechanism of impaired organ function. Congestion is the predominant clinical profile in most patients with AHF; a smaller proportion presents with peripheral hypoperfusion or cardiogenic shock. Hypoperfusion further deteriorates organ function. The injury and dysfunction of target organs (i.e. heart, lungs, kidneys, liver, intestine, brain) in the setting of AHF are associated with increased risk for mortality. Improvement in organ function after decongestive therapies has been associated with a lower risk for post-discharge mortality. Thus, the prevention and correction of organ dysfunction represent a therapeutic target of interest in AHF and should be evaluated in clinical trials. Treatment strategies that specifically prevent, reduce or reverse organ dysfunction remain to be identified and evaluated to determine if such interventions impact mortality, morbidity and patient-centred outcomes. This paper reflects current understanding among experts of the presentation and management of organ impairment in AHF and suggests priorities for future research to advance the field. © 2017 The Authors.

    Haemodynamic changes after intravenous administration of 0.4 mg beta-methyldigoxin or 0.4 mg digoxin daily were measured on the first to fourth day in 42 patients in heart failure after onset of transmural myocardial infarction. Regular reduction in filling pressure and increased stroke volume while arterial blood pressure remained unaltered pointed to improved contractility. Digitalization in the first few days after infarction achieved sustained tendency towards improved haemodynamics. It is concluded that early digitalization is indicated in patients with acute myocardial infarction if there are signs of heart failure.

    The prognostic significance of prior heart failure in acute coronary syndromes has not been well studied. Accordingly, we evaluated the baseline characteristics, management patterns and clinical outcomes in patients with acute coronary syndromes who had prior heart failure. The study population consisted of acute coronary syndrome patients in the Global Registry of Acute Coronary Events, expanded Global Registry of Acute Coronary Events and Canadian Registry of Acute Coronary Events between 1999 and 2008. Of the 13,937 eligible patients (mean age 66±13 years, 33% female and 28.3% with ST-elevation myocardial infarction), 1498 (10.7%) patients had a history of heart failure. Those with prior heart failure tended to be older, female and had lower systolic blood pressure, higher Killip class and creatinine on presentation. Prior heart failure was also associated with significantly worse left ventricular systolic function and lower rates of cardiac catheterization and coronary revascularization. The group with previous heart failure had significantly higher rates of acute decompensated heart failure, cardiogenic shock, myocardial (re)infarction and mortality in hospital. In multivariable analysis, prior heart failure remained an independent predictor of in-hospital mortality (odds ratio 1.48, 95% confidence interval 1.08-2.03, p=0.015). Prior heart failure was associated with high risk features on presentation and adverse outcomes including higher adjusted in-hospital mortality in acute coronary syndrome patients. However, acute coronary syndrome patients with prior heart failure were less likely to receive evidence-based therapies, suggesting potential opportunities to target more intensive treatment to improve their outcome. © The European Society of Cardiology 2015.

    Full Text Available Objectives. Evaluation of the characteristics of sleep apnea (SA in patients hospitalized with acute heart failure, considering that undiagnosed SA could contribute to early rehospitalization. Methods. 56 consecutive patients (13 women, 43 men, mean age 63.12 years with acute heart failure, in stable condition, underwent nocturnal polygraphy before hospital discharge. The type and severity of SA was determined. Besides descriptive statistics, correlations between the severity of SA and clinical and paraclinical characteristics were also analyzed (t-test, chi-square test, significancy at alpha 30/h. The apnea was predominantly obstructive (32 cases vs. 12 with central SA. Comparing the patients with mild or no SA with those with severe SA, we did not find statistically significant correlations (p>0.05 between the severity of SA and the majority of main clinical and paraclinical characteristics - age, sex, BMI, cardiac substrates of heart failure, comorbidities. Paradoxically, arterial hypertension (p=0.028 and atrial fibrillation (p=0.041 were significantly more prevalent in the group with mild or no SA. Conclusions. Before discharge, in the majority of patients hospitalized with acute heart failure moderate and severe SA is present, and is not related to the majority of patient related factors. Finding of significant SA in this setting is important, because its therapy could play an important role in preventing readmissions and improving prognosis.

    More than 30% of patients hospitalized for heart failure are rehospitalized or die within 90 days of discharge. Lower health literacy is associated with mortality among outpatients with chronic heart failure; little is known about this relationship after hospitalization for acute heart failure. Patients hospitalized for acute heart failure and discharged home between November 2010 and June 2013 were followed through December 31, 2013. Nurses administered the Brief Health Literacy Screen at admission; low health literacy was defined as Brief Health Literacy Screen ≤9. The primary outcome was all-cause mortality. Secondary outcomes were time to first rehospitalization and, separately, time to first emergency department visit within 90 days of discharge. Cox proportional hazards models determined their relationships with health literacy, adjusting for age, gender, race, insurance, education, comorbidity, and hospital length of stay. For the 1379 patients, average age was 63.1 years, 566 (41.0%) were female, and 324 (23.5%) had low health literacy. Median follow-up was 20.7 months (interquartile range 12.8 to 29.6 months), and 403 (29.2%) patients died. Adjusted hazard ratio [aHR] for death among patients with LHL was 1.32 (95%confidence interval [CI] 1.05, 1.66, P=0.02) compared to BHLS>9 [corrected].Within 90 days of discharge, there were 415 (30.1%) rehospitalizations and 201 (14.6%) emergency department visits, with no evident association with health literacy. Lower health literacy was associated with increased risk of death after hospitalization for acute heart failure. There was no evident relationship between health literacy and 90-day rehospitalization or emergency department visits. © 2015 The Authors.

    Although noninvasive positive pressure ventilation (NIPPV) for patients with acute decompensated heart failure was introduced almost 20 years ago, the variation in its use among hospitals remains unknown. We sought to define hospital practice patterns of NIPPV use for acute decompensated heart failure and their relationship with intubation and mortality. We conducted a cross-sectional study using a database maintained by Premier, Inc., that includes a date-stamped log of all billed items for hospitalizations at >400 hospitals. We examined hospitalizations for acute decompensated heart failure in this database from 2005 to 2010 and included hospitals with annual average volume of >25 such hospitalizations. We identified 384 hospitals that encompassed 524 430 hospitalizations (median annual average volume: 206). We used hierarchical logistic regression models to calculate hospital-level outcomes: risk-standardized NIPPV rate, risk-standardized intubation rate, and in-hospital risk-standardized mortality rate. We grouped hospitals into quartiles by risk-standardized NIPPV rate and compared risk-standardized mortality rates and risk-standardized intubation rates across quartiles. Median risk-standardized NIPPV rate was 6.2% (interquartile range, 2.8%-9.3%; 5th percentile, 0.2%; 95th percentile, 14.8%). There was no clear pattern of risk-standardized mortality rates across quartiles. The bottom quartile of hospitals had higher risk-standardized intubation rate (11.4%) than each of the other quartiles (9.0%, 9.7%, and 9.1%; Pvariation exists among hospitals in the use of NIPPV for acute decompensated heart failure without evidence for differences in mortality. There may be a threshold effect in relation to intubation rates, with the lowest users of NIPPV having higher intubation rates. © 2014 American Heart Association, Inc.

  10. Triple Diuretics and Aquaretic Strategy for Acute Decompensated Heart Failure due to Volume Overload

    Directory of Open Access Journals (Sweden)

    Rita Jermyn

    2013-01-01

    Full Text Available Diuretics, including furosemide, metolazone, and spironolactone, have historically been the mainstay of therapy for acute decompensated heart failure patients. The addition of an aquaretic-like vasopressin antagonist may enhance diuresis further. However, clinical experience with this quadruple combination is lacking in the acute setting. We present two hospitalized patients with acute decompensated heart failure due to massive fluid overload treated with a combination strategy of triple diuretics in conjunction with the aquaretic tolvaptan. The first patient lost 72.1 lbs. (32.7 kg with an average urine output of 3.5 to 7.5 L/day over eight days on combined therapy with furosemide, metolazone, spironolactone, and tolvaptan. The second patient similarly achieved a weight loss of 28.2 lbs. (12.8 kg over 4 days on the same treatment. Both patients maintained stable serum sodium, potassium, and creatinine over this period and remained out of the hospital for more than 30 days. Thus, patients hospitalized with acute decompensated heart failure due to volume overload can achieve euvolemia rapidly and without electrolytes disturbances using this regimen, while being under the close supervision of a team of cardiologists and nephrologists. Additionally, this therapy can potentially decrease the need for ultrafiltration and the length of hospital stay.

    Results from the DOSE-AHF study suggest that an initial continuous infusion of loop diuretics is not superior to bolus dosing with regard to clinical endpoints in acute heart failure. We hypothesized that outpatient furosemide dose was associated with congestion and poorer renal function and explored the hypothesis that a continuous infusion may be more effective in patients on higher outpatient diuretic doses. The DOSE-AHF study randomized 308 patients within 24 hours of admission to high versus low initial intravenous diuretic dose given as either a continuous infusion or bolus. We compared baseline characteristics and assessed associations between mode of administration (bolus vs continuous) and outcomes in patients receiving high-dose (≥120 mg furosemide equivalent, n = 177) versus low-dose (diuretics. Patients on higher doses of furosemide were less frequently on renin-angiotensin system inhibitors (P = .01) and had worse renal function and more advanced symptoms. There was a significant interaction between outpatient dose and mode of therapy (P = .01) with respect to net fluid loss at 72 hours after adjusting for creatinine and intensification strategy. Admission diuretic dose was associated with an increased risk of death or rehospitalization at 60 days (adjusted hazard ratio 1.08 per 20-mg increment in dose, 95% CI 1.01-1.16, P = .03). In acute heart failure, patients on higher diuretic doses have greater disease severity and may benefit from an initial bolus strategy. Copyright © 2012 Mosby, Inc. All rights reserved.

    Nutritional status has been related to clinical outcomes in patients with heart failure. We assessed the association between nutritional status, indexed by prognostic nutritional index (PNI), and survival in patients hospitalized for acute heart failure. A total of 1673 patients (age 76±13 years, 68% men) hospitalized for acute heart failure in a tertiary medical center were analyzed. PNI was calculated as 10×serum albumin (g/dL)+0.005×total lymphocyte count (per mm(3)). National Death Registry was linked to identify the clinical outcomes of all-cause and cardiovascular death. With increasing tertiles of PNI, age and N-terminal probrain natriuretic peptide decreased, and body mass index, estimated glomerular filtration rate, and hemoglobin increased. During a mean follow-up duration of 31.5 months, a higher PNI tertile was related to better survival free from all-cause and cardiovascular mortality in the total study population and in participants with either reduced or preserved left ventricular ejection fraction. After accounting for age, sex, estimated glomerular filtration rate, left ventricular ejection fraction, serum sodium level, and on-admission systolic blood pressure, PNI was independently associated with cardiovascular death and total mortality (hazard ratio per 1 SD of the natural logarithm of the PNI: 0.76 [95% CI, 0.66-0.87] and 0.79 [95% CI, 0.73-0.87], respectively). In subgroup analyses stratified by age, sex, left ventricular ejection fraction, body mass index, or estimated glomerular filtration rate, PNI was consistently related to mortality. PNI is independently associated with long-term survival in patients hospitalized for acute heart failure with either reduced or preserved left ventricular ejection fraction. © 2017 The Authors.

    Measurement of the inferior vena cava (IVC) diameters may improve decision-making for patients hospitalized with acute decompensated heart failure. Nevertheless, little is known about how the IVC is affected by loop diuretics. We sought to determine if bolus infusions of intravenous furosemide affect IVC diameters measured by hand-carried ultrasonography. We conducted a prospective cohort study at a public teaching hospital from September 2009 through June 2010. Physician investigators performed IVC ultrasonography on a convenience sample of 70 hospitalized adults who were prescribed intravenous furosemide for the diagnosis of acute decompensated heart failure. Participants' median baseline IVC diameter was 2.38 cm (interquartile range, 1.91-2.55 cm). At 1-2 hours after furosemide, IVC diameters decreased an average of 0.21 cm (95% CI, 0.13-0.29 cm) and remained significantly below baseline at 2-3 hours after furosemide by an average of 0.15 cm (95% CI, 0.07-0.22 cm). IVC diameters of adults diagnosed with acute decompensated heart failure become measurably smaller after single doses of intravenous furosemide. Whether this represents a true change in volume status has not been studied. © 2014 Wiley Periodicals, Inc.

Given her normal ADAMSTS13 activity, evidence of increased complement activation, and renal biopsy showing evidence of thrombotic microangiopathy, she was diagnosed with complement-mediated HUS. She subsequently developed acute hypoxemic respiratory failure secondary to pulmonary edema requiring intubation and mechanical ventilation. A transthoracic echocardiogram showed evidence of a Takotsubo cardiomyopathy with an estimated left ventricular ejection fraction of 20%, though ischemic cardiomyopathy could not be ruled out. Treatment was initiated with eculizumab. After several failed attempts at extubation, she eventually underwent tracheotomy. She also required hemodialysis to improve her uremia and hypervolemia. After seven weeks of hospitalization and five doses of eculizumab, her renal function and respiratory status improved, and she was discharged in stable condition on room air and independent of hemodialysis. Our case illustrates a rare association between acute systolic heart failure and complement-mediated HUS and highlights the potential of eculizumab in stabilizing even the most critically-ill patients with complement-mediated disease.

    The purpose of this consensus document was to reach an agreement among experts on the multidisciplinary care of patients with acute heart failure. Starting with a narrative review of the care provided to these patients and a critical analysis of the healthcare procedures, we identified potential shortcomings and improvements and formalised a document on recommendations for optimising the clinical and therapeutic approach for acute heart failure. This document was validated through an in-person group session guided using participatory techniques. The process resulted in a set of 36 recommendations formulated by experts of the Spanish Society of Cardiology, the Spanish Society of Internal Medicine and the Spanish Society of Urgent and Emergency Care. The recommendations are designed to optimise the healthcare challenge presented by the care of patients with acute heart failure in the context of Spain's current National Health System.

    Although the presence of brucella endocarditis is encountered rarely, it is the most fetal complication of brucellosis, which is shown to affect the aortic valve primarily and the mitral valve secondarily. Involvement of the tricuspid valve is extremely rare. A 62-year-old female was admitted with complaints of fever, fatigue, difficulty in breathing, and swellings in her legs. A transthoracic echocardiogram was performed since acute right heart failure was considered due to her symptoms. The echocardiogram showed enlarged right heart chambers, serious tricuspid valve insufficiency, and a mass on the tricuspid valve compatible with a vegetation moving in and out of the right ventricle. Although no growths were observed in the blood culture, antibody titration for brucellosis was found to be 1/640 (+) in the serological examination. The patient was diagnosed with brucella endocarditis and placed on doxycycline, rifampicin, and ceftriaxone treatment for eight weeks. At the end of the eight-week treatment, the symptoms of right heart failure receded and the patient recovered from the endocarditis. Tricuspid valve brucella endocarditis should be considered in patients suffering from acute right heart failure accompanied by systemic infection findings since brucellosis is presently endemic in Turkey.

    Women have an increased risk of rehospitalization in the immediate postdischarge period; however, few studies have determined how readmission risk dynamically changes on a day-to-day basis over the full year after hospitalization by sex and how these differences compare with the risk for mortality. We identified >3 000 000 hospitalizations of patients with a principal discharge diagnosis of heart failure, acute myocardial infarction, or pneumonia and estimated sex differences in the daily risk of rehospitalization/death 1 year after discharge from a population of Medicare fee-for-service beneficiaries aged 65 years and older. We calculated the (1) time required for adjusted rehospitalization/mortality risks to decline 50% from maximum values after discharge, (2) time required for the adjusted readmission risk to approach plateau periods of minimal day-to-day change, and (3) extent to which adjusted risks are greater among recently hospitalized patients versus Medicare patients. We identified 1 392 289, 530 771, and 1 125 231 hospitalizations for heart failure, acute myocardial infarction, and pneumonia, respectively. The adjusted daily risk of rehospitalization varied by admitting condition (hazard rate ratio for women versus men, 1.10 for acute myocardial infarction; hazard rate ratio, 1.04 for heart failure; and hazard rate ratio, 0.98 for pneumonia). However, for all conditions, the adjusted daily risk of death was higher among men versus women (hazard rate ratio women versus with men, <1). For both sexes, there was a similar timing of peak daily risk, half daily risk, and reaching plateau. Although the association of sex with daily risk of rehospitalization varies across conditions, women are at highest risk after discharge for acute myocardial infarction. Future studies should focus on understanding the determinants of sex differences in rehospitalization risk among conditions. © 2017 American Heart Association, Inc.

    Little is know about the outcomes of acute heart failure (AHF) with acute coronary syndrome (ACS-AHF), compared to those without ACS (NACS-AHF). We conducted a prospective registry of AHF patients involving 18 hospitals in Saudi Arabia between October 2009 and December 2010. In this sub-study, we compared the clinical correlates, management and hospital course, as well as short, and long-term outcomes between AHF patients with and without ACS. Of the 2609 AHF patients enrolled, 27.8 % presented with ACS. Compared to NACS-AHF patients, ACS-AHF patients were more likely to be old males (Mean age = 62.7 vs. 60.8 years, p = 0.003, and 73.8 % vs. 62.7 %, p prevalence of severe LV systolic dysfunction (EF coronary angiography and had higher prevalence of multi-vessel coronary artery disease (p < 0.001 for all comparisons). The unadjusted hospital and one-month mortality were higher in ACS-AHF patients (OR = 1.6 (1.2-2.2), p = 0.003 and 1.4 (1.0-1.9), p = 0.026 respectively). A significant interaction existed between the level of left ventricular ejection fraction and ACS-AHF status. After adjustment, ACS-AHF status was only significantly associated with hospital mortality (OR = 1.6 (1.1-2.4), p = 0.019). The three-years survival following hospital discharge was not different between the two groups. AHF patients presenting with ACS had worse hospital prognosis, and an equivalent long-term survival compared to AHF patients without ACS. These findings underscore the importance of timely recognition and management of AHF patients with concomitant ACS given their distinct presentation and underlying pathophysiology compared to other AHF patients.

    Extracorporeal membrane oxygenation was introduced as a supplement ot mechanical ventilation in the treatment of two patients with severe acute respiratory failure and as heart assist in one patient with acute refractory cardiac failure after open heart surgery. The system includes a membrane oxygenator and a roller pump. The whole circuit is coated with partially degraded heparin covalently bound to the surface (Carmeda Bioactive Surface), reducing the need of systemic heparinization to a minimum. In the first case of acute respiratory failure a veno-venous bypass was employed, with cannulas in the right atrium and the femoral vein. Given a blood flow through the circuit of 2.5 l/min, ventilator settings could be favourably reduced. The patient was weaned off the bypass system after six days, off the ventilator after 120 days, and recovered completely. In two cases the system served as partial venoarterial bypass, and blood was returned to the ascending aorta. A 31 year-old male victim of a smoke inhalation lung injury was on bypass for four and a half days. He recovered completely after another 17 days of mechanical ventilation. A 68 year-old man with pump failure after cardiac surgery needed extracorporeal support as heart assist for seven days. On the eighth day he was weaned off intra-aortic balloon-pumping as well. Unfortunately, he died of septicemia, with multiple organ failure, 13 days later. The heparin-coated extracorporeal membrane oxygenation system may represent a major advancement in the treatment of critically ill patients in need of cardiopulmonary assist.

    Small studies suggest that low-dose dopamine or low-dose nesiritide may enhance decongestion and preserve renal function in patients with acute heart failure and renal dysfunction; however, neither strategy has been rigorously tested. To test the 2 independent hypotheses that, compared with placebo, addition of low-dose dopamine (2 μg/kg/min) or low-dose nesiritide (0.005 μg/kg/min without bolus) to diuretic therapy will enhance decongestion and preserve renal function in patients with acute heart failure and renal dysfunction. Multicenter, double-blind, placebo-controlled clinical trial (Renal Optimization Strategies Evaluation [ROSE]) of 360 hospitalized patients with acute heart failure and renal dysfunction (estimated glomerular filtration rate of 15-60 mL/min/1.73 m2), randomized within 24 hours of admission. Enrollment occurred from September 2010 to March 2013 across 26 sites in North America. Participants were randomized in an open, 1:1 allocation ratio to the dopamine or nesiritide strategy. Within each strategy, participants were randomized in a double-blind, 2:1 ratio to active treatment or placebo. The dopamine (n = 122) and nesiritide (n = 119) groups were independently compared with the pooled placebo group (n = 119). Coprimary end points included 72-hour cumulative urine volume (decongestion end point) and the change in serum cystatin C from enrollment to 72 hours (renal function end point). Compared with placebo, low-dose dopamine had no significant effect on 72-hour cumulative urine volume (dopamine, 8524 mL; 95% CI, 7917-9131 vs placebo, 8296 mL; 95% CI, 7762-8830 ; difference, 229 mL; 95% CI, -714 to 1171 mL; P = .59) or on the change in cystatin C level (dopamine, 0.12 mg/L; 95% CI, 0.06-0.18 vs placebo, 0.11 mg/L; 95% CI, 0.06-0.16; difference, 0.01; 95% CI, -0.08 to 0.10; P = .72). Similarly, low-dose nesiritide had no significant effect on 72-hour cumulative urine volume (nesiritide, 8574 mL; 95% CI, 8014-9134 vs placebo

    Acute heart failure and/or cardiogenic shock are frequently triggered by ischemic coronary events. Yet, there is a paucity of randomized data on the management of patients with heart failure complicating acute coronary syndrome, as acute coronary syndrome and cardiogenic shock have frequently been defined as exclusion criteria in trials and registries. As a consequence, guideline recommendations are mostly driven by observational studies, even though these patients have a particularly poor prognosis compared to heart failure patients without signs of coronary artery disease. In acute heart failure, and especially in cardiogenic shock related to ischemic conditions, vasopressors and inotropes are used. However, both pathophysiological considerations and available clinical data suggest that these treatments may have disadvantageous effects. The inodilator levosimendan offers potential benefits due to a range of distinct effects including positive inotropy, restoration of ventriculo-arterial coupling, increases in tissue perfusion, and anti-stunning and anti-inflammatory effects. In clinical trials levosimendan improves symptoms, cardiac function, hemodynamics, and end-organ function. Adverse effects are generally less common than with other inotropic and vasoactive therapies, with the notable exception of hypotension. The decision to use levosimendan, in terms of timing and dosing, is influenced by the presence of pulmonary congestion, and blood pressure measurements. Levosimendan should be preferred over adrenergic inotropes as a first line therapy for all ACS-AHF patients who are under beta-blockade and/or when urinary output is insufficient after diuretics. Levosimendan can be used alone or in combination with other inotropic or vasopressor agents, but requires monitoring due to the risk of hypotension. Copyright © 2016 The Authors.

    Full Text Available Abstract Background: Heart failure is accompanied by abnormalities in ventricular-vascular interaction due to increased myocardial and arterial stiffness. Galectin-3 is a recently discovered biomarker that plays an important role in myocardial and vascular fibrosis and heart failure progression. Objectives: The aim of this study was to determine whether galectin-3 is correlated with arterial stiffening markers and impaired ventricular-arterial coupling in decompensated heart failure patients. Methods: A total of 79 inpatients with acute decompensated heart failure were evaluated. Serum galectin-3 was determined at baseline, and during admission, transthoracic echocardiography and measurements of vascular indices by Doppler ultrasonography were performed. Results: Elevated pulse wave velocity and low arterial carotid distensibility are associated with heart failure in patients with preserved ejection fraction (p = 0.04, p = 0.009. Pulse wave velocity, carotid distensibility and Young’s modulus did not correlate with serum galectin-3 levels. Conversely, raised galectin-3 levels correlated with an increased ventricular-arterial coupling ratio (Ea/Elv p = 0.047, OR = 1.9, 95% CI (1.0‑3.6. Increased galectin-3 levels were associated with lower rates of left ventricular pressure rise in early systole (dp/dt (p=0.018 and raised pulmonary artery pressure (p = 0.046. High galectin-3 levels (p = 0.038, HR = 3.07 and arterial pulmonary pressure (p = 0.007, HR = 1.06 were found to be independent risk factors for all-cause mortality and readmissions. Conclusions: This study showed no significant correlation between serum galectin-3 levels and arterial stiffening markers. Instead, high galectin-3 levels predicted impaired ventricular-arterial coupling. Galectin-3 may be predictive of raised pulmonary artery pressures. Elevated galectin-3 levels correlate with severe systolic dysfunction and together with pulmonary hypertension are independent markers of

  6. More Efficient Sodium Removal by Ultrafiltration Compared to Diuretics in Acute Heart Failure; Underexplored and Overstated.

    Kazory, Amir

    2016-01-01

    Enhanced removal of sodium has often been cited as an advantage of ultrafiltration (UF) therapy over diuretic-based medical treatment in the management of acute decompensated heart failure. However, so far clinical studies have rarely evaluated the precise magnitude of sodium removal, and this assumption is largely based on the physiologic mechanisms and anecdotal observations that predate the contemporary management of heart failure. Recent data suggest that patients treated with UF experience substantial reduction in urinary sodium excretion possibly due to prolonged intravascular volume contraction. Consequently, the efficient sodium extraction through production of isotonic ultrafiltrate can be offset by urine hypotonicity. Based on the limited currently available data, it seems unlikely that the persistent benefits of UF could be solely explained by its greater efficiency in sodium removal. The design of the future studies should include frequent measurements of urine sodium to precisely compare the impact of UF and diuretics on sodium balance. © 2016 S. Karger AG, Basel.

  7. Hyponatremia in acute decompensated heart failure: mechanisms, prognosis, and treatment options.

    Jao, Geoffrey T; Chiong, Jun R

    2010-11-01

    Hyponatremia is common and is increasingly recognized as an independent prognostic marker that adversely affects morbidity and mortality in various disease states, including heart failure. In acute decompensated heart failure (ADHF), the degree of hyponatremia often parallels the severity of cardiac dysfunction and is further exacerbated by any reduction in glomerular filtration rate and arginine vasopressin dysregulation. A recent study showed that even modest improvement of hyponatremia may have survival benefits. Although management of hyponatremia in ADHF has traditionally focused on improving cardiac function and fluid restriction, the magnitude of improvement of serum sodium is fairly slow and unpredictable. In this article, we discuss the mechanisms of hyponatremia in ADHF, review its evolving prognostic significance, and evaluate the efficacy of various treatments for hyponatremia, including the recently approved vasopressin receptor antagonists for managing hyponatremia among patients hospitalized for ADHF.

    Cardiogenic shock (CS) continues to have high mortality and morbidity despite advances in pharmacological, mechanical, and reperfusion approaches to treatment. When CS is refractory to medical therapy, percutaneous mechanical circulatory support (MCS) should be considered. Acute MCS devices, ranging from intra-aortic balloon pumps (IABPs) to percutaneous temporary ventricular assist devices (VAD) to extracorporeal membrane oxygenation (ECMO), can aid, restore, or maintain appropriate tissue perfusion before the development of irreversible end-organ damage. Technology has improved patient survival to recovery from CS, but in patients whom cardiac recovery does not occur, acute MCS can be effectively utilized as a bridge to long-term MCS devices and/or heart transplantation. Heart transplantation has been limited by donor heart availability, leading to a greater role of left ventricular assist device (LVAD) support. In patients with biventricular failure that are ineligible for LVAD implantation, further advancements in the total artificial heart (TAH) may allow for improved survival compared to medical therapy alone. In this review, we discuss the current state of acute and durable MCS, ongoing advances in LVADs and TAH devices, improved methods of durable MCS implantation and patient selection, and future MCS developments in this dynamic field that may allow for optimization of HF treatment.

    Acute heart failure (AHF) is a life-threatening disease requiring urgent treatment, including a recommendation for immediate initiation of loop diuretics. The authors prospectively evaluated the association between time-to-diuretic treatment and clinical outcome. REALITY-AHF (Registry Focused on Very Early Presentation and Treatment in Emergency Department of Acute Heart Failure) was a prospective, multicenter, observational cohort study that primarily aimed to assess the association between time to loop diuretic treatment and clinical outcome in patients with AHF admitted through the emergency department (ED). Door-to-furosemide (D2F) time was defined as the time from patient arrival at the ED to the first intravenous furosemide injection. Patients with a D2F time furosemide within 24 h of ED arrival, the median D2F time was 90 min (IQR: 36 to 186 min), and 481 patients (37.3%) were categorized as the early treatment group. These patients were more likely to arrive by ambulance and had more signs of congestion compared with the nonearly treatment group. In-hospital mortality was significantly lower in the early treatment group (2.3% vs. 6.0% in the nonearly treatment group; p = 0.002). In multivariate analysis, earlier treatment remained significantly associated with lower in-hospital mortality (odds ratio: 0.39; 95% confidence interval: 0.20 to 0.76; p = 0.006). In this prospective multicenter, observational cohort study of patients presenting at the ED for AHF, early treatment with intravenous loop diuretics was associated with lower in-hospital mortality.

    Diuretics are widely recommended in patients with acute heart failure (AHF). However, loop diuretics predispose patients to electrolyte imbalance and hypovolemia, which in turn leads to neurohormonal activation and worsening renal function (WRF). Unfortunately, despite their widespread use, limited data from randomized clinical trials are available to guide clinicians with the appropriate management of this diuretic therapy. This review focuses on the current management of diuretic therapy and discusses data supporting the efficacy and safety of loop diuretics in patients with AHF. The authors consider the challenges in performing clinical trials of diuretics in AHF, and describe ongoing clinical trials designed to rigorously evaluate optimal diuretic use in this syndrome. The authors review the current evidence for diuretics and suggest hypothetical bases for their efficacy relying on the complex relationship among diuretics, neurohormonal activation, renal function, fluid and sodium management, and heart failure syndrome. Data from several large registries that evaluated diuretic therapy in hospitalized patients with AHF suggest that its efficacy is far from being universal. Further studies are warranted to determine whether high-dose diuretics are responsible for WRF and a higher rate of coexisting renal disease are instead markers of more severe heart failure. The authors believe that monitoring congestion during diuretic therapy in AHF would refine the current approach to AHF treatment. This would allow clinicians to identify high-risk patients and possibly reduce the incidence of complications secondary to fluid management strategies.

    Tolvaptan, a vasopressin type 2 receptor antagonist, has an aquaretic effect without affecting renal function. The effects of long-term tolvaptan administration in heart failure patients with renal dysfunction have not been clarified. Here, we assessed the clinical benefit of tolvaptan during a 6-month follow-up in acute decompensated heart failure (ADHF) patients with severe chronic kidney disease (CKD; estimated glomerular filtration rate (eGFR) tolvaptan in addition to loop diuretics (TLV group), with 36 patients with ADHF and severe CKD who were administered high-dose loop diuretics (≥40 mg) alone (LD group). Alterations in serum creatinine and eGFR levels from the time of hospital discharge to 6-month follow-up were significantly different between the groups, with those in the TLV group being more favorable. Furthermore, Kaplan-Meier analysis revealed that rehospitalization for heart failure (HF) was significantly lower in the TLV group compared with the LD group. In ADHF patients with severe CKD, tolvaptan use for 6 months reduced worsening of renal function and rehospitalization rates for HF when compared with conventional diuretic therapy. In conclusion, tolvaptan could be a safe and effective agent for long-term management of HF and CKD.

    Full Text Available Objective: to evaluate the structural and functional state of the right cardiac cavities in acute left ventricular myocardial infarction and in progressive chronic heart failure (CHF in patients with coronary heart disease.Materials and methods. 20 patients with acute myocardial infarction and 48 with postinfarct cardiosclerosis with NYHA functional classes I to IV CHF were examined. The structural and functional state of the right heart was evaluated in progressive left ventricular systolic and diastolic dysfunction by echocardiography.Results. In the acute period of infarction, remodeling processes occur in the left ventricle, with normal postload values, volumetric indices and right ventricular contractility are in the normal range. There is right cardiac dilatation at the early stage of left ventricular systolic and diastolic dysfunction in postinfarct remodeling and evolving CHF, normal pulmonary arterial and right atrial pressures. With a significant reduction in left ventricular contractility and its pronounced filling impairment, increases in post- and preload for the right ventricle occur with a just considerable change in its structural and functional state.Conclusion. In impaired myocardial relaxation in the presence of CHF, remodeling of the right cardiac cavities takes place without the influence of a hemodynamic factor. There is a close relationship of remodeling of both ventricles from the very early CHF stages, which suggests that there are common pathogenetic mechanisms responsible for the development of myocardial dysfunction.

    To study the means of emergency transport used to bring patients with acute heart failure (AHF) to hospital emergency departments (EDs) and explore associations between factors, type of transport, and prehospital care received. We gathered the following information on patients treated for AHF at 34 Spanish hospital EDs: means of transport used (medicalized ambulance [MA], nonmedicalized ambulance [NMA], or private vehicle) and treatments administered before arrival at the hospital. Twenty-seven independent variables potentially related to type of transport used were also studied. Indicators of AHF severity were triage level assigned in the ED, need for admission, need for intensive care, in-hospital mortality, and 30-day mortality. A total of 6106 patients with a mean (SD) age of 80 years were included; 56.5% were women, 47.2% arrived in PVs, 37.8% in NMAs, and 15.0% in MAs. Use of an ambulance was associated with female sex, age over 80 years, chronic obstructive pulmonary disease, a history of AHF, functional dependency, New York Heart Association class III-IV, sphincteral incontinence, labored breathing, orthopnea, cold skin, and sensory depression or restlessness. Assignment of a MA was directly associated with living alone, a history of ischemic heart disease, cold skin, sensory depression or restlessness, and high temperature; it was inversely associated with a history of falls. The rates of receipt of prehospital treatments and AHF severity level increased with use of MAs vs. NMAs vs. PV. Seventy-three percent of patients transported in MAs received oxygen, 29% received a diuretic, 13.5% a vasodilator, and 4.7% noninvasive ventilation. Characteristics of the patient with AHF are associated with the assignment of type of transport to a hospital ED. Assignment appears to be related to severity. Treatment given during MA transport could be increased.

    Heart failure (HF) afflicts nearly 6 million Americans, resulting in one million emergency department (ED) visits and over one million annual hospital discharges. An aging population and improved survival from cardiovascular diseases is expected to further increase HF prevalence. Emergency providers play a significant role in the management of patients with acute heart failure (AHF). It is crucial that emergency physicians and other providers involved in early management understand the latest developments in diagnostic testing, therapeutics and alternatives to hospitalization. Further, clinical trials must be conducted in the ED in order to improve the evidence base and drive optimal initial therapy for AHF. Should ongoing and future studies suggest early phenotype-driven therapy improves in-hospital and post-discharge outcomes, ED treatment decisions will need to evolve accordingly. The potential impact of future studies which incorporate risk-stratification into ED disposition decisions cannot be underestimated. Predictive instruments that identify a cohort of patients safe for ED discharge, while simultaneously addressing barriers to successful outpatient management, have the potential to significantly impact quality of life and resource expenditures.

    Worsening renal function in heart failure may be related to increased venous congestion, decreased cardiac output, or both. Diuretics are universally used in acute decompensated heart failure, but they may be ineffective and may lead to azotemia. We aimed to compare the decongestive properties of a urine output-guided diuretic adjustment and standard therapy for the management of cardiorenal syndrome in acute decompensated heart failure. Data were pooled from subjects randomized to the stepwise pharmacologic care algorithm (SPCA) in the CARRESS-HF trial and those who developed cardiorenal syndrome (rise in creatinine >0.3 mg/dL) in the DOSE-AHF and ROSE-AHF trials. Patients treated with SPCA (n = 94) were compared with patients treated with standard decongestive therapy (SDT) that included intravenous loop diuretic use (DOSE-AHF and ROSE-AHF; n = 107) at the time of cardiorenal syndrome and followed for net fluid balance, weight loss, and changing renal function. The SPCA group had higher degrees of jugular venous pressure (P cardiorenal syndrome. The group that received SPCA had more weight change (-3.4 ± 5.2 lb) and more net fluid loss (1.705 ± 1.417 L) after 24 hours than the SDT group (-0.8 ± 3.4 lb and 0.892 ± 1.395 L, respectively; P < .001 for both) with a slight improvement in renal function (creatinine change -0.1 ± 0.3 vs 0.0 ± 0.3 mg/dL, respectively; P = .03). Compared with SDT, patients who received an intensification of medication therapy for treating persisting congestion had greater net fluid and weight loss without being associated with renal compromise.

    Limited data exist comparing the efficacy and safety of bumetanide- or metolazone-based diuretic regimens to furosemide in acute heart failure (HF). Our purpose was to evaluate the comparative effect on urine output (UO) and renal function between these regimens. A retrospective study of hospitalized HF patients treated with continuous infusion furosemide (CIF), combination furosemide plus metolazone (F + M), or continuous infusion bumetanide (CIB). Primary end points were between regimen comparisons for change in mean hourly UO versus baseline and incidence of worsening renal function. Data on 242 patients with acute HF (age 58 ± 12 years, 63% male, left ventricular ejection fraction 38% ± 17%) were analyzed (160 CIF, 42 F + M, 40 CIB). The mean duration of diuretic regimens was 41 ± 32 hours. Compared to baseline, all regimens increased mean hourly UO (P furosemide is combined with metolazone or when bumetanide is used. These therapeutic differences warrant prospective study.

    Clinical trials involving novel therapies treating acute heart failure syndromes (AHFS) have shown limited success with regard to both efficacy and safety. As a direct result, outcomes have changed little over time and AHFS remains a disease process associated with largely no change in hospitalization rates (80%), hospital length of stay (median 4.5 days), and in-hospital (4-7%) and 60-day mortality (10%). Despite extensive emergency department (ED) involvement during the initial phase of AHFS management, clinical trials have enrolled patients after the ED phase of management, up to 48 hours after initial therapy, long after many patients have experienced significant beneficial effects of standard therapy. As standard therapy has provided symptomatic improvement in up to 70% of patients in these trials, it is not surprising that investigational agents started after 24 to 48 hours of standard therapy have shown limited clinical efficacy when compared with standard therapy. The ability to screen, enroll, and randomize in the emergency setting is fundamental. The unique environment, the ethical complexities of enrollment in emergency-based research, and the need for rapid and standardized study-compliant care represent key challenges to active recruitment in AHFS studies. Specifically, the ability to identify and enroll a large cohort of AHFS patients early (academic physicians with experience in clinical trials and acute management of heart failure who together can surmount this barrier and provide a framework for conducting early trials in AHFS.

    Several clinical studies have evaluated the association between ST2 and outcome in patients with heart failure (HF). However, little is known about the predictive value of frequently measured ST2 levels in patients with acute HF. This study sought to describe the prognostic value of baseline and repeated ST2 measurements in patients with acute HF. In the TRIUMPH (Translational Initiative on Unique and novel strategies for Management of Patients with Heart failure) clinical cohort study, 496 patients with acute HF were enrolled in 14 hospitals in the Netherlands between 2009 and 2014. Repeated blood samples (7) were drawn during 1-year follow-up. ST2 and N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels were measured in a central laboratory. The primary endpoint was the composite of all-cause mortality and HF rehospitalization. Associations between repeated biomarker measurements and the primary endpoint were assessed using a joint model. Median age was 74 years, and 37% of patients were women. The primary endpoint was reached in 188 patients (40%) during a median follow-up of 325 days (interquartile range: 85 to 401). The median baseline ST2 level was 71 ng/ml (interquartile range: 46 to 102). After adjustment for clinical factors and NT-proBNP, baseline ST2 was associated with an increased risk of the primary endpoint, and the hazard ratio per 1 SD increase of the baseline ST2 level (on the log2 scale) was 1.30 (95% confidence interval: 1.08 to 1.56; p = 0.005). When repeated measurements were taken into account, the adjusted hazard ratio per 1 SD increase of the ST2 level (on the log2 scale) during follow-up increased to 1.85 (95% confidence interval: 1.02 to 3.33; p = 0.044), adjusted for clinical factors and repeated measurements of NT-proBNP. Furthermore, ST2 levels appeared to elevate several weeks before the time of the primary endpoint. Repeated ST2 measurements appeared to be a strong predictor of outcome in patients with acute HF

    The oral vasopressin-2 receptor antagonist tolvaptan causes aquaresis in patients with volume overload, potentially facilitating decongestion and improving the clinical course of patients with acute heart failure (AHF). The TACTICS-HF (Targeting Acute Congestion with Tolvaptan in Congestive Heart Failure) study was conducted to address the acute use of tolvaptan to improve congestion in AHF. The TACTICS-HF study randomized patients (n = 257) within 24 h of AHF presentation in a prospective, double blind, placebo-controlled trial. Patients were eligible regardless of ejection fraction, and were randomized to either 30 mg of tolvaptan or placebo given at 0, 24, and 48 h, with a fixed-dose furosemide regimen as background therapy. The primary endpoint was the proportion of patients considered responders at 24 h. Secondary endpoints included symptom improvement, changes in renal function, and clinical events. Dyspnea relief by Likert scale was similar between groups at 8 h (25% moderately or markedly improved with tolvaptan vs. 28% placebo; p = 0.59) and at 24 h (50% tolvaptan vs. 47% placebo; p = 0.80). Need for rescue therapy was also similar at 24 h (21% tolvaptan, 18% placebo; p = 0.57). The proportion defined as responders at 24 h (primary study endpoint) was 16% for tolvaptan and 20% for placebo (p = 0.32). Tolvaptan resulted in greater weight loss and net fluid loss compared with placebo, but tolvaptan-treated patients were more likely to experience worsening renal function during treatment. There were no differences in in-hospital or post-discharge clinical outcomes. In patients hospitalized with AHF, dyspnea, and congestion, the addition of tolvaptan to a standardized furosemide regimen did not improve the number of responders at 24 h, despite greater weight loss and fluid loss.

    2014-03-01

    Diagnosis of acute heart failure (HF) is difficult in elderly patients with multiple comorbidities. Risk scales and classification criteria based exclusively on clinical manifestations, such as the Framingham scales, lack sufficient specificity. In addition to clinical manifestations, diagnosis should be based on two key factors: natriuretic peptides and echocardiographic study. When there is clinical suspicion of acute HF, a normal natriuretic peptide level will rule out this process. When a consistent clinical suspicion is present, an echocardiographic study should also be performed. Diagnosis of HF with preserved ejection fraction (HF/pEF) requires detection of an enlarged left atrium or the presence of parameters of diastolic dysfunction. Elevation of cardiac biomarkers seems to be due to myocardial injury and the compensatory mechanisms of the body against this injury (hormone and inflammatory response and repair mechanisms). Elevation of markers of cardiac damage (troponins and natriuretic peptides) have been shown to be useful both in the diagnosis of acute HF and in prediction of outcome. MMP-2 could be useful in the diagnosis of HF/pEF. In addition to biomarkers with diagnostic value, other biomarkers are helpful in prognosis in the acute phase of HF, such as biomarkers of renal failure (eGFR, cystatin and urea), inflammation (cytokines and CRP), and the cell regeneration marker, galectin-3. A promising idea that is under investigation is the use of panels of biomarkers, which could allow more accurate diagnosis and prognosis of acute HF. Copyright © 2014 Elsevier España, S.L.

    Diabetes, chronic obstructive pulmonary disease (COPD) and anemia are comorbidities with a high prevalence and impact in heart failure (HF). The presence of these comorbidities considerably worsens the prognosis of HF. Diabetic patients have a higher likelihood of developing symptoms of HF and both the treatment of diabetes and that of acute HF are altered by the coexistence of both entities. The glycemic targets in patients with acute HF are not well-defined, but could show a U-shaped relationship. Stress hyperglycemia in non-diabetic patients with HF could also have a deleterious effect on the medium-term prognosis. The inter-relationship between COPD and HF hampers diagnosis due to the overlap between the symptoms and signs of both entities and complementary investigations. The treatment of acute HF is also altered by the presence of COPD. Anemia is highly prevalent and is often the direct cause of decompensated HF, the most common cause being iron deficiency anemia. Iron replacement therapy, specifically intravenous forms, has helped to improve the prognosis of acute HF. Copyright © 2014 Elsevier España, S.L. All rights reserved.

    The involvement of the immune system in heart failure (HF) has been demonstrated. Evidence shows that innate immunity can have a role in the remodeling process and progression of HF. With previous studies showing the prognostic value of some innate immunity markers and their relevance in this condition, we aim to evaluate how these markers vary on hospitalization due to an acute episode of HF and at discharge. About 154 patients admitted with acute HF were prospectively recruited. Patients were evaluated on admission and at discharge from the hospital. Patients with infection were separately analyzed. Innate immunity, inflammatory, and cardiac biomarkers were measured and were compared between groups and between admission and discharge and with reference values of biological variation. Median patients' age was 78 years, and half of the patients were men. The median duration of hospitalization was 6 days. C3 and C4 protein levels significantly increased (P innate immunity markers such as C3 and C4 increase after treatment for acute HF, supporting the hypothesis that they can be involved in the resolution of the acute episode. © 2016 Wiley Periodicals, Inc.

    The ROSE AHF trial (Renal Optimization Strategies Evaluation in Acute Heart Failure) found that when compared with placebo, neither low-dose dopamine (2 µg/kg per minute) nor low-dose nesiritide (0.005 μg/kg per minute without bolus) enhanced decongestion or preserved renal function in AHF patients with renal dysfunction. However, there may be differential responses to vasoactive agents in AHF patients with reduced versus preserved ejection fraction (EF). This post hoc analysis examined potential interaction between treatment effect and EF (EF ≤40% versus >40%) on the ROSE AHF end points. ROSE AHF enrolled AHF patients (n=360; any EF) with renal dysfunction. The coprimary end points were cumulative urine volume and the change in serum cystatin-C in 72 hours. The effect of dopamine (interaction P=0.001) and nesiritide (interaction P=0.039) on urine volume varied by EF group. In heart failure with reduced EF, urine volume was higher with active treatment versus placebo, whereas in heart failure with preserved EF, urine volume was lower with active treatment. The effect of dopamine and nesiritide on weight change, sodium excretion, and incidence of AHF treatment failure also varied by EF group (interaction Pfailure with reduced EF and worse clinical outcomes in heart failure with preserved EF. With nesiritide, there were no differences in clinical outcomes when compared with placebo in both heart failure with reduced EF and heart failure with preserved EF. In this post hoc analysis of ROSE AHF, the response to vasoactive therapies differed in patients with heart failure with reduced EF and heart failure with preserved EF. Investigations of AHF therapies should assess the potential for differential responses in AHF with preserved versus reduced EF. URL: http://www.clinicaltrials.gov.

    Full Text Available Background. Diuresis is a major therapy for the reduction of congestive symptoms in acute decompensated heart failure (ADHF patients. We previously reported the efficacy and safety of tolvaptan compared to carperitide in hospitalized patients with ADHF. There were some reports of cardio- and renal-protective effects in carperitide; therefore, the purpose of this study was to compare the long-term effects of tolvaptan and carperitide on cardiorenal function and prognosis. Methods and Results. One hundred and five ADHF patients treated with either tolvaptan or carperitide were followed after hospital discharge. Levels of plasma B-type natriuretic peptide, serum sodium, potassium, creatinine, and estimated glomerular filtration rate were measured before administration of tolvaptan or carperitide at baseline, the time of discharge, and one year after discharge. These data between tolvaptan and carperitide groups were not different one year after discharge. Kaplan-Meier survival curves demonstrated that the event-free rate regarding all events, cardiac events, all cause deaths, and rehospitalization due to worsening heart failure was not significantly different between tolvaptan and carperitide groups. Conclusions. We demonstrated that tolvaptan had similar effects on cardiac and renal function and led to a similar prognosis in the long term, compared to carperitide.

    Though commonly noted in clinical practice, it is unknown if decongestion in acute heart failure (AHF) results in increased serum bicarbonate. For 678 AHF patients in the DOSE-AHF, CARRESS-HF, and ROSE-AHF trials, we assessed change in bicarbonate (baseline to 72-96 hours) according to decongestion strategy, and the relationship between bicarbonate change and protocol-defined decongestion. Median baseline bicarbonate was 28 mEq/L. Patients with baseline bicarbonate ≥28 mEq/L had lower ejection fraction, worse renal function and higher N-terminal pro-B-type natriuretic peptide than those with baseline bicarbonate  .1). In CARRESS-HF, bicarbonate increased with pharmacologic care but decreased with ultrafiltration (median +3.3 vs -0.9 mEq/L, respectively; P  .2 for all trials). In AHF, serum bicarbonate is most commonly elevated in patients with more severe heart failure. Despite being used in clinical practice as an indicator for decongestion, change in serum bicarbonate was not associated with significant decongestion. Copyright © 2016 Elsevier Inc.

We investigated patients with HF in Acute Study of Clinical Effectiveness of Nesiritide in Decompensated Heart Failure who were discharged on either torsemide or furosemide. Using inverse probability weighting to account for the nonrandom selection of diuretic, we assessed the relation between choice of diuretic at discharge with 30-day mortality or HF hospitalization and 180-day mortality. Of 7,141 patients in the trial, 4,177 patients were included in this analysis, of which 87% (n = 3,620) received furosemide and 13% (n = 557) received torsemide. Torsemide-treated patients had lower ejection fraction and blood pressure and higher creatinine and natriuretic peptide level compared with furosemide. Torsemide was associated with similar outcomes on unadjusted analysis and nominally lower events on adjusted analysis (30-day mortality/HF hospitalization odds ratio 0.89, 95% CI 0.62 to 1.29, p = 0.55 and 180-day mortality hazard ratio 0.86, 95% CI 0.63 to 1.19, p = 0.37). In conclusion, these data are hypothesis-generating and randomized comparative effectiveness trials are needed to investigate the optimal diuretic choice. Copyright © 2016 Elsevier Inc.

    Background. Diuresis is a major therapy for the reduction of congestive symptoms in acute decompensated heart failure (ADHF) patients. We previously reported the efficacy and safety of tolvaptan compared to carperitide in hospitalized patients with ADHF. There were some reports of cardio- and renal-protective effects in carperitide; therefore, the purpose of this study was to compare the long-term effects of tolvaptan and carperitide on cardiorenal function and prognosis. Methods and Results. One hundred and five ADHF patients treated with either tolvaptan or carperitide were followed after hospital discharge. Levels of plasma B-type natriuretic peptide, serum sodium, potassium, creatinine, and estimated glomerular filtration rate were measured before administration of tolvaptan or carperitide at baseline, the time of discharge, and one year after discharge. These data between tolvaptan and carperitide groups were not different one year after discharge. Kaplan-Meier survival curves demonstrated that the event-free rate regarding all events, cardiac events, all cause deaths, and rehospitalization due to worsening heart failure was not significantly different between tolvaptan and carperitide groups. Conclusions. We demonstrated that tolvaptan had similar effects on cardiac and renal function and led to a similar prognosis in the long term, compared to carperitide. PMID:25436213

    There is a shortage of data about acute heart failure (AHF) in the young, including its underlying causes, clinical presentation and outcomes. We aim to describe clinical characteristics, causes and outcomes of AHF in Yemeni patients aged 50years or younger. we evaluated Yemeni patients with AHF enrolled in Gulf CARE registry. Patients were divided into two groups: young patients (≤50years) and older patients (>50years). A total of 1536 patients with AHF were enrolled, of whom 635 (41.3%) were 50years old or younger. The mean age for this group was 38.8 (±9.5) years; and 399 (62.8%) were males. Younger patients had a higher prevalence of non-ischemic cardiomyopathy (41% vs 11.1%, pvalvular disease (27.9% vs 3.2%, pdisease (61.6% vs 25.5%, pdisease (18.3% vs 6.3%, p<0.001) were more frequent in the elderly group. Cardiogenic shock was more frequent among younger patients (13.7% vs 7.0, p<0.001). In-hospital mortality was higher in patient aged ≤50years (12% vs 7.6%, p=0.002) while no difference in all-cause mortality was present at 3months (17.8 vs 14.5, p=0.089) and after 1year (21.9% vs 20.6%, p=0.56). This analysis of Gulf CARE registry represents the largest report of patients admitted with AHF in Yemen. There were differences among cause of HF and precipitating factors of AHF among younger and elderly patients. Younger patients had higher in-hospital mortality and more severe clinical condition at admission. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    Muscle passive contraction of lower limb by neuromuscular electrostimulation (NMES) is frequently used in chronic heart failure (CHF) patients but no data are available concerning its action on sympathetic activity. However, Transcutaneous Electrical Nerve Stimulation (TENS) is able to improve baroreflex in CHF. The primary aim of the present study was to investigate the acute effect of TENS and NMES compared to Sham stimulation on sympathetic overactivity as assessed by Muscle Sympathetic Nerve Activity (MSNA). We performed a serie of two parallel, randomized, double blinded and sham controlled protocols in twenty-two CHF patients in New York Heart Association (NYHA) Class III. Half of them performed stimulation by TENS, and the others tested NMES. Compare to Sham stimulation, both TENS and NMES are able to reduce MSNA (63.5 ± 3.5 vs 69.7 ± 3.1 bursts / min, p < 0.01 after TENS and 51.6 ± 3.3 vs 56.7 ± 3.3 bursts / min, p < 0, 01 after NMES). No variation of blood pressure, heart rate or respiratory parameters was observed after stimulation. The results suggest that sensory stimulation of lower limbs by electrical device, either TENS or NMES, could inhibit sympathetic outflow directed to legs in CHF patients. These properties could benefits CHF patients and pave the way for a new non-pharmacological approach of CHF.

    Full Text Available Introduction. Levosimendan is a novel positive inotropic agent which, improves myocardial contractility through its calcium-sensitizing action, without causing an increase in myocardial oxygen demand. Also, by opening ATP-sensitive potassium channels, it causes vasodilatation with the reduction in both afterload and preload. Because of the long halflife, its effects last for up 7 to 9 days after 24-hour infusion. Case report. We presented three patients 2, 15 and 17 years old. All the patients had severe acute deterioration of the previously diagnosed chronic heart failure (dilatative cardiomyopathy; univentricular heart with bidirectional Glenn anastomosis and restrictive bulboventricular foramen; bacterial endocarditis on artificial aortic valve with severe stenosis and regurgitation. Signs and symptoms of severe heart failure, cardiomegaly (cardio-thoracic index 0.65 and left ventricular dilatation (end-diastolic diameter z-score 2.6; 4.1 and 4.0 were confirmed on admission. Also, myocardial contractility was poor with ejection fraction (EF - 27%, 25%, 35%, fractional shortening (FS - 13%, 11%, 15% and stroke volume (SV - 40, 60, 72 mL/m2. The treatment with standard intravenous inotropic agents resulted in no improvement but in clinical deterioration. Thus, standard intravenous inotropic support was stopped and levosimendan treatment was introduced. All the patients received a continuous 24-h infusion 0.1 μg/kg/min of levosimendan. In a single patient an initial loading dose of 11 μg/kg over 10 min was administrated, too. Levosimendan treatment resulted in both clinical and echocardiography improvement with the improved EF (42%, 34%, 44%, FS (21%, 16%, 22% and SV (59, 82, 93 mL/m2. Hemodynamic improvement was registered too, with the reduction in heart rate in all the treated patients from 134-138 bpm before, to less than 120 bpm after the treatment. These parameters were followed by the normalization of lactate levels. Nevertheless, left

    Pheochromocytoma is a rare tumor in adults, with an estimated annual incidence of 0.8 per 100,000 persons. Cardiomyopathy is an uncommon presentation of such a rare disease. Serious cardiovascular complications of these tumors are related to potent effects of secreted catecholamines. The mechanism of pheochromocytoma-related cardiomyopathy is not well understood but it is likely due to the effect of excess catecholamines and their oxidation products which have been found to have a direct toxic effect on the myocardium. We describe below a case of a 70-year old female with uncontrolled hypertension and new onset acute systolic heart failure, who on further evaluation was noted to have pheochromocytoma-related cardiomyopathy. Pheochromocytoma should be strongly considered in the differential diagnosis of non-ischemic cardiomyopathy for a patient with elevated blood pressures relative to severity of cardiac dysfunction.

    Renal function, as quantified by the estimated glomerular filtration rate (eGFR), is a predictor of death in acute heart failure (AHF). It is unknown whether one of the clinically-available serum creatinine-based formulas to calculate eGFR is superior to the others for predicting mortality. We quantified renal function using five different formulas (Cockroft-Gault, MDRD-4, MDRD-6, CKD-EPI in patientsrenal function and in three vulnerable subgroups: women, patients with severe left ventricular dysfunction, and the elderly. The prognostic accuracy for readmission was poor for all equations, with an AUC around 0.5. Calculating eGFR using the Cockcroft-Gault formula assesses the risk of mortality in patients with AHF more accurately than other commonly used formulas. Copyright © 2015 Elsevier Ireland Ltd.

    Most patients hospitalized for acutely decompensated heart failure (ADHF) present with symptoms and signs of volume overload, which are also associated with high rates of death and re-hospitalization. Several studies have investigated the possible use of extracorporeal ultrafiltration in the management of ADHF, evaluating potential clinical benefits in terms of hospitalization and survival rates versus those of conventional diuretic therapy. Though ultrafiltration remains an extremely appealing therapeutic option for patients with AHDF, some of the most recent studies have reported conflicting results. Differences in the selection of study population, heterogeneity of the indications for the use of ultrafiltration, disparity in the ultrafiltration protocols, and high variability in the pharmacologic therapies used for the control group could explain some of these contradictory findings. The purpose of the present review is to provide an overview and an update on the mechanisms and clinical effects of ultrafiltration and on currently available evidence supporting its use in ADHF.

    No study has investigated the admission echocardiographic characteristics of acute heart failure (AHF) patients who are resistant to conventional diuretics and require tolvaptan. We retrospectively analyzed the echocardiographic characteristics of AHF patients who were resistant to conventional diuretics and took tolvaptan (tolvaptan group: 26 patients), and compared them to those who were sensitive to conventional diuretics (conventional group: 180 patients). The tolvaptan group had a higher left atrial volume index (96.0 ± 85.0 mL/m2 vs. 45.8 ± 25.9 mL/m2, p tolvaptan had no significant echocardiographic differences compared to the non-responders. The admission echocardiographic characteristics of AHF patients requiring tolvaptan included a larger left atrium, inferior vena cava, and more severe tricuspid regurgitation. Echocardiography may provide useful information for the early and appropriate initiation of tolvaptan.

    The role of echocardiography in the risk stratification of acute heart failure (HF) is unknown. Some small studies and retrospective analyses have found little change in echocardiographic variables during admission for acute HF and some echocardiographic parameters were not found to be associated with outcomes. It is unknown which echocardiographic variables will predict outcomes in sub-Saharan African patients admitted with acute HF. Using echocardiograms, this study aimed to determine the predictors of death and re-admissions within 60 days and deaths up to 180 days in patients with acute heart failure. Out of the 1 006 patients in the THESUS-HF registry, 954 had had an echocardiogram performed within a few weeks of admission. Echocardiographic measurements were performed according to the American Society of Echocardiography guidelines. We examined the associations between each echocardiographic predictor and outcome using regression models. Heart rate and left atrial size predicted death within 60 days or re-admission. Heart rate, left ventricular posterior wall thickness in diastole (PWTd), and presence of aortic stenosis were associated with the risk of death within 180 days. PTWd added to clinical variables in predicting 180-day mortality rates. Echocardiographic variables, especially those of left ventricular size and function, were not found to have additional predictive value in patients admitted for acute HF. Left atrial size, aortic stenosis, heart rate and measures of hypertrophy (LV PWTd) had some predictive value, suggesting the importance of early treatment of hypertension and severe valvular heart disease.

    Several clinical studies have evaluated the association between galectin-3 levels and outcome in patients with heart failure (HF). However, little is known about the predictive value of repeated galectin-3 measurements. This study evaluates the prognostic value of repeated time-dependent galectin-3 measurements in acute HF patients. In the TRIUMPH (Translational Initiative on Unique and Novel Strategies for Management of Patients with Heart Failure) clinical cohort study, 496 acute HF patients were enrolled in 14 hospitals in The Netherlands, between 2009 and 2014. Repeated blood samples (7) were drawn during 1-year follow-up. Associations between repeated biomarker measurements and the primary end point were assessed using a joint model. Median age was 74 years and 37% were women. The primary end point, composite of all-cause mortality and HF rehospitalization, was reached in 188 patients (40%), during a median follow-up of 325 days (interquartile range 85-401). The median baseline galectin-3 level was 24 ng/mL (interquartile range 18-34). The mean number of galectin-3 measurements available per patient was 4.3. After adjustment for clinical factors and N-terminal pro-brain natriuretic peptide, there was a weak association between baseline galectin-3 and risk of the primary end point. When repeated measurements were taken into account, the adjusted hazard ratio per 1 SD increase of the galectin-3 level (on the log2 scale) at any time point increased to 1.67 (95% confidence interval, 1.24-2.23, P<0.001). After additional adjustment for repeated N-terminal pro-brain natriuretic peptide measurements, the association remained statistically significant. Repeated galectin-3 measurements appeared to be a strong predictor of outcome in acute HF patients, independent of N-terminal pro-brain natriuretic peptide. Hence, galectin-3 may be helpful in clinical practice for prognostication and treatment monitoring. © 2017 The Authors and Koninklijke Philips. Published on

    2011-07-01

    Cardiovascular disease is the principle cause of death in Latin America. Data from the World Health Organization indicate that the region is currently experiencing a large-scale epidemic of cardiovascular disease. This could be attributable to demographic and lifestyle changes inherent in the epidemiologic transition: one consequence of increased life-expectancy is longer exposure to cardiovascular risk factors, which results in a higher probability of adverse events. Latin America is one of the regions of the world with the highest burden of cardiovascular risk factors, particularly overweight, dyslipidemia and diabetes mellitus. These factors will have a significant impact on the incidence of coronary events and heart failure in the near future. In addition, infectious conditions, especially Chagas disease and rheumatic fever, affect large sections of the population in the region. Unless preventive measures are introduced in the next three to four decades, the number of deaths due to cardiovascular disease in the region will increase by more than 200%. Data currently available indicate that mortality in patients with acute coronary syndrome is greater in Latin America than in developed countries. Among the possible factors that could explain this finding are the underuse of therapies that have been shown to be effective and the more conservative and later use of surgical and percutaneous interventions. In Latin America, heart failure occurs in younger subjects than in the rest of the world and is most frequently related to ischemic heart disease. However, Chagas disease is close to hypertension as the second most common cause. There is an urgent need for well-designed epidemiologic studies to guide the implementation of preventive measures and appropriate treatment. Copyright © 2011 Sociedad Española de Cardiología.

    Full Text Available Background/Aim. Acute heart failure (AHF is one of the most common diseases in emergency medicine, associated with poor prognosis and high in-hospital and longterm mortality. The aim of this study was to investigate characteristics, outcomes and one year mortality of patients with AHF in the local population. Methods. This prospective study consisted of 64 consecutive unselected patients treated in the Coronary Care Unit of the Emergency Centre (Clinical Center of Serbia, Belgrade and were followed for one year after the discharge. Results. Mean age of the patients was 63.6 ± 12.6 years and 59.4% were males. Acute congestion (43.8% and pulmonary edema (39.1% were the most common presentations of AHF. Mean left ventricular ejection fraction (LVEF was 39.7% ± 9.25%, while 44.4% of the patients had LVEF ≥ 50%. At discharge, 55.9% of the patients received therapy with β-blockers, 94.9% diuretics, out of which 47.7% spironolactone, 94.9% patients were given ACE-inhibitors or angiotensin receptor blokcers (ARB. The 12-month all-cause mortality was 26.5%. Independent predictors of one year mortality were previous hospitalization due to heart disease, reduced LVEF, reduced fraction of shortening (FS and a higher tricuspid velocity. Conclusion. One year mortality of our patients with AHF was high, similar to the known European studies. Independent predictors of one year mortality were previous hospitalization due to heart disease, reduced LVEF and LVFS and a higher tricuspid velocity.

    Patients with advanced heart failure (HF) enroll in hospice at low rates, and data on their acute medical service utilization after hospice enrollment is limited. We performed a descriptive analysis of Medicare fee-for-service beneficiaries, with at least one home health claim between July 1, 2009, and June 30, 2010, and at least 2 HF hospitalizations between July 1, 2009, and December 31, 2009, who subsequently enrolled in hospice between July 1, 2009, and December 31, 2009. We estimated panel-negative binomial models on a subset of beneficiaries to compare their acute medical service utilization before and after enrollment. Our sample size included 5073 beneficiaries: 55% were female, 45% were ≥85 years of age, 13% were non-white, and the mean comorbidity count was 2.38 (standard deviation 1.22). The median number of days between the second HF hospital discharge and hospice enrollment was 45. The median number of days enrolled in hospice was 15, and 39% of the beneficiaries died within 7 days of enrollment. During the study period, 11% of the beneficiaries disenrolled from hospice at least once. The adjusted mean number of hospital, intensive care unit, and emergency room admissions decreased from 2.56, 0.87, and 1.17 before hospice enrollment to 0.53, 0.19, and 0.76 after hospice enrollment. Home health care Medicare beneficiaries with advanced HF who enrolled in hospice had lower acute medical service utilization after their enrollment. Their pattern of hospice use suggests that earlier referral and improved retention may benefit this population. Further research is necessary to understand hospice referral and palliative care needs of advanced HF patients. © 2017 American Heart Association, Inc.

However, its relationship with the pro-inflammatory response and prognostic value in consecutive patients with acute decompensated heart failure (ADHF has not been investigated.We measured HRR and pro-inflammatory markers in 107 prospectively and consecutively enrolled, recovered ADHF patients (71 male, 59 ± 15 years, mean ejection fraction 28.9 ± 14.2% during the pre-discharge period. The primary endpoint included cardiovascular (CV events defined as CV mortality, cardiac transplantation, or rehospitalization due to HF aggravation.The CV events occurred in 30 (28.0% patients (5 cardiovascular deaths and 7 cardiac transplantations during the follow-up period (median 214 days, 11-812 days. When the patients with ADHF were grouped by HRR according to the Contal and O'Quigley's method, low HRR was shown to be associated with significantly higher levels of serum monokine-induced by gamma interferon (MIG and poor clinical outcome. Multivariate Cox regression analysis revealed that low HRR was an independent predictor of CV events in both enter method and stepwise method. The addition of HRR to a model significantly increased predictability for CV events across the entire follow-up period.Impaired post-exercise HRR is associated with a pro-inflammatory response and independently predicts clinical outcome in patients with ADHF. These findings may explain the relationship between autonomic dysfunction and clinical outcome in terms of the inflammatory response in these patients.

    In-hospital worsening heart failure (WHF) occurs frequently in patients hospitalized for acute heart failure (AHF) and has strongly negative prognostic associations. It may be a useful endpoint in studies of AHF management but important questions remain regarding optimization of its definition and variability in its incidence. Our objective was to survey the full extent of clinical interest in WHF and assess the impact of baseline variables and trial design on outcomes. PubMed, Embase, and BIOSIS were searched systematically for clinical studies that had in-hospital WHF as an endpoint. Differences in definitions of in-hospital WHF were reviewed for their potential impact on observed incidence of WHF and its associations with post-discharge outcomes. The search identified 35 publications representing 13 interventional trials, 3 observational studies, several different classes of therapeutic agent, and 78,752 patients overall. Incidence of in-hospital WHF varied greatly-from 4.2% to 37%. Concerning the impact of differences in the way in which WHF was defined, two important factors were physician determination of worsening and whether intensification of diuretic therapy alone was defined as a WHF event. Patients having in-hospital WHF were at substantially greater risk for death and longer length of stay during index hospitalizations, all-cause and heart-failure rehospitalization, cardiovascular complications, renal failure, all-cause death, cardiovascular death, and higher healthcare costs post-discharge. There is diverse interest in selecting in-hospital WHF as an endpoint in clinical trials. Differences in reported incidence are complexly related to differences in the way in which WHF is defined.

    Deregulation of microRNAs (miRNAs) may be involved in the pathogenesis of heart failure (HF) and renal disease. Our aim is to describe miRNA levels related to early worsening renal function in acute HF patients. We studied the association between 12 circulating miRNAs and Worsening Renal Function (WRF; defined as an increase in the serum creatinine level of 0.3mg per deciliter or more from admission to day 3), absolute change in creatinine and Neutrophil Gelatinase Associated Lipocalin (NGAL) from admission to day 3 in 98 patients hospitalized for acute HF. At baseline, circulating levels of all miRNAs were lower in patients with WRF, with statistically significant decreased levels of miR-199a-3p, miR-423-3p, and miR-let-7i-5p (p-valueacute HF were consistently lower in patients who developed worsening of renal function. MiR-199a-3p was the best predictor of WRF in these patients. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    Contradictory results have been reported on the effects of nesiritide on renal function in patients with acute decompensated heart failure. We studied the effects of nesiritide on renal function during hospitalization for acute decompensated heart failure and associated outcomes. A total of 7141 patients were randomized to receive either nesiritide or placebo and creatinine was recorded in 5702 patients at baseline, after infusion, discharge, peak/nadir levels until day 30. Worsening renal function was defined as an increase of serum creatinine >0.3 mg/dL and a change of ≥25%. Median (25(th)-75(th) percentile) baseline creatinine was 1.2 (1.0-1.6) mg/dL and median baseline blood urea nitrogen was 25 (18-39) mmol/L. Changes in both serum creatinine and blood urea nitrogen were similar in nesiritide-treated and placebo-treated patients (P=0.20 and P=0.41) from baseline to discharge. In a multivariable model, independent predictors of change from randomization to hospital discharge in serum creatinine were a lower baseline blood urea nitrogen, higher systolic blood pressure, lower diastolic blood pressure, previous weight gain, and lower baseline potassium (all Prenal function during hospitalization was similar in the nesiritide and placebo group (14.1% and 12.8%, respectively; odds ratio with nesiritide 1.12; confidence interval, 0.95-1.32; P=0.19) and was not associated with death alone and death or rehospitalization at 30 days. However, baseline, discharge, and change in creatinine were associated with death alone and death or rehospitalization for heart failure (all tests, Prenal function in patients with acute decompensated heart failure.

    The treatment of atrial tachycardia in critically ill patients can be difficult. Nine cases were presented with atrial tachyarrhythmias (mean heart rate > 130 beats/min) and left heart failure. Congestive heart failure was diagnosed in 6 patients (ejection fraction heart failure in 3 patients (ejection infarction > 55%). The infusion of amiodarone (450 mg over 10 min and 0.5 mg/min after the bolus administration) was associated with a decrease in heart rate 31 beats/min and an increase in systolic blood pressure of 13 mm Hg after one hour. There was only one adverse effect secondary to amiodarone therapy. In this case the sinus rhythm converted within 24 hours but T-waves alternans and short running torsade de pointes ventricular tachycardia was observed and amiodarone therapy was discontinued.

    Although diabetes mellitus is frequently associated with heart failure (HF), the association between elevated admission glucose levels and adverse outcomes has not been well established in hospitalized patients with acute HF. We prospectively evaluated in-hospital mortality, post-discharge 1-year mortality and 1-year re-hospitalization rates in the Italian Network on Heart Failure (IN-HF) Outcome registry cohort of 1776 patients hospitalized with acute HF and stratified by their admission glucose levels (i.e., known diabetes, newly diagnosed hyperglycemia, no diabetes). Compared with those without diabetes (n = 586), patients with either known diabetes (n = 749) (unadjusted-odds ratio [OR] 1.64, 95%CI 0.99–2.70) or newly diagnosed hyperglycemia (n = 441) (unadjusted-OR 2.34, 95%CI 1.39–3.94) had higher in-hospital mortality, but comparable post-discharge 1-year mortality rates. After adjustment for age, sex, systolic blood pressure, estimated glomerular filtration rate, left ventricular ejection fraction, HF etiology and HF worsening/de novo presentation, the results remained unchanged in patients with known diabetes (adjusted-OR 1.86, 95%CI 1.01–3.42), while achieved borderline significance in those with newly diagnosed hyperglycemia (adjusted-OR 1.81, 95%CI 0.95–3.45). One-year re-hospitalization rates were lower in patients with newly diagnosed hyperglycemia (adjusted-hazard ratio 0.74, 95%CI 0.56–0.96) than in other groups. Elevated admission blood glucose levels are associated with poorer in-hospital survival outcomes in patients with acute HF, especially in those with previously known diabetes. This finding further highlights the importance of tight glycemic control during hospital stay and address the need of dedicated intervention studies to identify customized clinical protocols to improve in-hospital survival of these high-risk patients.

    Acute decompensated heart failure (ADHF) is a leading cause of hospitalization in older persons in the United States. Reduced physical function and frailty are major determinants of adverse outcomes in older patients with hospitalized ADHF. However, these are not addressed by current heart failure (HF) management strategies and there has been little study of exercise training in older, frail HF patients with recent ADHF. Targeting physical frailty with a multi-domain structured physical rehabilitation intervention will improve physical function and reduce adverse outcomes among older patients experiencing a HF hospitalization. REHAB-HF is a multi-center clinical trial in which 360 patients ≥60 years hospitalized with ADHF will be randomized either to a novel 12-week multi-domain physical rehabilitation intervention or to attention control. The goal of the intervention is to improve balance, mobility, strength and endurance utilizing reproducible, targeted exercises administered by a multi-disciplinary team with specific milestones for progression. The primary study aim is to assess the efficacy of the REHAB-HF intervention on physical function measured by total Short Physical Performance Battery score. The secondary outcome is 6-month all-cause rehospitalization. Additional outcome measures include quality of life and costs. REHAB-HF is the first randomized trial of a physical function intervention in older patients with hospitalized ADHF designed to determine if addressing deficits in balance, mobility, strength and endurance improves physical function and reduces rehospitalizations. It will address key evidence gaps concerning the role of physical rehabilitation in the care of older patients, those with ADHF, frailty, and multiple comorbidities. Copyright © 2017 Elsevier Inc.

    Cardiorenal syndrome (CRS) is common in acute heart failure (AHF), and is associated with dire prognosis. Levosimendan, a positive inotrope that also has diuretic effects, may improve patients' renal profile. Published results are conflicting. We aimed to assess the incidence of CRS in AHF patients according to the inotrope used and to determine its predictors in order to identify patients who could benefit from the most renoprotective inotrope. In a retrospective study, 108 consecutive patients with AHF who required inotropes were divided into two groups according to the inotrope used (levosimendan vs. dobutamine). The primary endpoint was CRS incidence. Follow-up for mortality and readmission for AHF was conducted. Seventy-one percent of the study population were treated with levosimendan and the remainder with dobutamine. No differences were found in heart failure etiology or chronic kidney disease. At admission, the dobutamine group had lower blood pressure; there were no differences in estimated glomerular filtration rate or cystatin C levels. The levosimendan group had lower left ventricular ejection fraction. CRS incidence was higher in the dobutamine group, and they more often had incomplete recovery of renal function at discharge. In multivariate analysis, cystatin C levels predicted CRS. The dobutamine group had higher in-hospital mortality, of which CRS and the inotrope used were predictors. Levosimendan appears to have some renoprotective effect, as it was associated with a lower incidence of CRS and better recovery of renal function at discharge. Identification of patients at increased risk of renal dysfunction by assessing cystatin C may enable more tailored therapy, minimizing the incidence of CRS and its negative impact on outcome in AHF.

    Loop diuretics are first-line medications for congestive heart failure (CHF); however, they are associated with serious adverse effects, including decreased renal function, and sympathetic nervous and renin-angiotensin system activation. We tested whether tolvaptan, a vasopressin V2-receptor antagonist, could reduce unfavourable furosemide-induced effects during CHF treatment. Sixty patients emergently hospitalized owing to CHF-induced dyspnea were randomly assigned to receive either 40 mg intravenous furosemide daily or 7.5 mg oral tolvaptan for 5 days after admission. Both groups also received intravenous carperitide and canrenoate potassium. As results, baseline patient characteristics were similar between the furosemide (n = 30) and the tolvaptan (n = 30) groups, with no significant difference in 5 day urine volume or fluid balance. Brain natriuretic peptide and body weight improvements were similar between groups. However, serum creatinine (Cr) level did not increase, and the incidence of worsening renal function was significantly lower in the tolvaptan group. Consequently, the Cr increase to gain 1000 mL urine was 2.5-fold lower in the tolvaptan group. Furthermore, the blood urea nitrogen (BUN)/Cr ratio significantly decreased in the tolvaptan group, suggesting that renal perfusion was preserved, and urea reuptake and passive water reabsorption were suppressed following tolvaptan treatment. Although catecholamine improvements after treatment were not significantly different, plasma renin activity was enhanced in the furosemide group. As compared with furosemide, tolvaptan in patients with acute heart failure is associated with comparable decongestion, better preservation of renal function and less activation of renin-angiotensin system.

    This study investigated the relationship between the initial diuretic response to tolvaptan and clinical predictors for tolvaptan responders in patients with acute decompensated heart failure (ADHF). Patients (153) with ADHF (clinical scenario 2 or 3 with signs of fluid retention) who were administered tolvaptan were enrolled. Tolvaptan (15 or 7.5 mg) was administered for at least 7 days to those patients in whom fluid retention was observed even after standard treatment. The maximum urine volume immediately after tolvaptan administration showed good correlations with the ejection fraction and estimated glomerular filtration rate that were independent predictors of the urine volume (UV) responders (≥1500 mL increase in urine volume). The diuretic response (in terms of maximum diuresis) diminished with advancing chronic kidney disease (CKD) stage and concomitant deterioration of the renal function. Furthermore, advanced CKD was a significant negative predictor for the body weight (BW) responders (2.0% decrease in the body weight within 1 week after starting tolvaptan). As compared with non-CKD, the presence of advanced CKD predicts poor diuretic response for both UV and BW responders. The diuretic response following tolvaptan administration gradually diminished with progressive deterioration of the CKD stage. Worsening renal function was not observed. Tolvaptan is effective in treating CS2 or CS3 ADHF patients who present fluid retention and congestion, suggesting its potential efficacy for fluid management in the ADHF patients with CKD without worsening the renal function. © 2017 The Authors.

    The new guidelines for the diagnosis and treatment of acute and chronic heart failure (HF) were presented in May 2016 during the congress of the Heart Failure Association (HFA) of the European Society of Cardiology (ESC) in Florence. An important amendment affects the classification of HF which now differentiates between HF with preserved ejection fraction (HFpEF) and left ventricular EF (LVEF) > 50%, HF with reduced ejection fraction (HFrEF, LVEF clinical presentation and from this prognosis and treatment options can be derived. The algorithm for the diagnosis of chronic HF is now based on the probability for HF in a 3-step model comprised of clinical presentation, patient history and electrocardiogram (ECG) abnormalities, together with increased plasma levels of N‑terminal propeptide brain natriuretic peptide (NT-proBNP, normal guidelines for the prevention of symptomatic HF in high-risk patients (class IIa/B indication). For cardiac resynchronization therapy (CRT) a novel class I/A indication for QRS > 150 ms and left bundle branch block (LBBB), a class I/B indication for QRS > 130 ms and LBBB as well as high-grade atrioventricular block with pacemaker indications have been put forward. The Life Vest® for bridging therapy of high-risk patients received a class IIb/C indication.

    Patients with acute heart failure (AHF) have high rates of attendance to emergency departments (EDs), with significant health care costs. We aimed to describe the clinical characteristics of patients attending Italian EDs for AHF and their diagnostic and therapeutic work-up. We carried out a retrospective analysis on 2683 cases observed in six Italian EDs for AHF (January 2011 to June 2012). The median age of patients was 84 years (interquartile range 12), with females accounting for 55.8% of cases (95% confidence interval [CI] 53.5-57.6%). A first episode of AHF was recorded in 55.3% (95% CI 55.4-57.2%). Respiratory disease was the main precipitating factor (approximately 30% of cases), and multiple comorbidities were recorded in > 50% of cases (history of acute coronary syndrome, chronic obstructive pulmonary disease, diabetes, chronic kidney disease, valvular heart disease). The treatment was based on oxygen (69.7%; 67.9-71.5%), diuretics (69.2%; 67.9-71.5%), nitroglycerin (19.7%; 18.3-21.4%), and noninvasive ventilation (15.2%; 13.8-16.6%). Death occurred within 6 h in 2.5% of cases (2.0-3.1%), 6.4% (5.5-7.3%) were referred to the care of their general practitioners within a few hours from ED attendance or after short-term (disease severity. Our study reporting the "real-world" clinical activity indicates that subjects attending the Italian EDs for AHF are rather different from those reported in international registries. Subjects are older, with a higher proportion of females, and high prevalence of cardiac and noncardiac comorbidities. Copyright © 2017 Elsevier Inc. All rights reserved.

    Acute heart failure (AHF) is a major public health issue due to high incidence and poor prognosis. Only a few studies are available on the long-term prognosis and on outcome predictors in the unselected population attending the emergency department (ED) for AHF. We carried out a 1-year follow-up analysis of 1234 consecutive patients from selected Italian EDs from January 2011 to June 2012 for an episode of AHF. Their prognosis and outcome-associated factors were tested by Cox proportional hazard model. Patients' mean age was 84, with 66.0% over 80 years and 56.2% females. Comorbidities were present in over 50% of cases, principally a history of acute coronary syndrome, chronic obstructive pulmonary disease, diabetes, chronic kidney disease, valvular heart disease. Death occurred within 6 h in 24 cases (1.9%). At 30-day follow-up, death was registered in 123 cases (10.0%): 110 cases (89.4%) died of cardiovascular events and 13 (10.6%) of non-cardiovascular causes (cancer, gastrointestinal hemorrhages, sepsis, trauma). At 1-year follow-up, all-cause death was recorded in 50.1% (over 3 out of 4 cases for cardiovascular origin). Six variables (older age, diabetes, systolic arterial pressure <110 mm/Hg, high NT pro-BNP, high troponin levels and impaired cognitive status) were selected as outcome predictors, but with limited discriminant capacity (AUC = 0.649; SE 0.015). Recurrence of AHF was registered in 31.0%. The study identifies a cluster of variables associated with 1-year mortality in AHF, but their predictive capacity is low. Old age and the presence of comorbidities, in particular diabetes are likely to play a major role in dictating the prognosis.

Recently, we reported that the baseline level of circulating miR-30d was associated with left ventricular remodeling in response to cardiac resynchronization therapy in advanced chronic heart failure patients. However, the role of circulating miR-30d as a prognostic marker of survival in patients with AHF has not been explored. Methods: Patients clinically diagnosed with AHF were enrolled and followed up for 1 year. Quantitative reverse transcription polymerase chain reactions were used to determine serum miR-30d levels. The univariate logistic regression analysis and multivariate logistic regression analysis were used to determine the predictors for all-cause mortality in AHF patients. Kaplan–Meier survival analysis was used to analyze the role of miR-30d in prediction of survival. Results: A total of 96 AHF patients were enrolled and followed up for 1 year. Serum miR-30d was significantly lower in AHF patients who expired in the one year follow-up period compared to those who survived. Univariate logistic regression analysis yielded 18 variables that were associated with all-cause mortality in AHF patients, while the multivariate logistic regression analysis identified 4 variables including heart rate, hemoglobin, serum sodium, and serum miR-30d level associated with mortality. ROC curve analysis showed that hemoglobin, heart rate and serum sodium displayed poor prognostic value for AHF (AUCs not higher than 0.700 compared to miR-30d level (AUC = 0.806. Kaplan–Meier survival analysis confirmed that patients with higher serum miR-30d levels had significantly lower mortality (P=0.001. Conclusion: In conclusion, this study shows evidence for the predictive value of circulating miR-30d as 1-year all-cause mortality in AHF patients. Large multicentre studies are further needed to validate

    Right heart failure (RHF), which is caused by a variety of heart and lung diseases, has a high morbidity and mortality rate. Levosimendan is a cardiac inotropic drug and vasodilator. The effect of levosimendan on RHF remains unclear. We sought to evaluate the efficacy and safety of levosimendan in patients with acute RHF. We systematically searched PubMed, Cochrane Library, EMBASE, and ClinicalTrials.gov to identify studies reporting the efficacy and safety of levosimendan for the treatment of RHF. Ten trials, including 359 participants from 6 RCTs and 4 self-controlled trials, were evaluated. In the 6 RCTs, we found that patients treated with levosimendan for 24h showed a significant increase in tricuspid annular plane systolic excursion [1.53; 95% CI (0.54, 2.53); P=0.002] and ejection fraction [3.59; 95% CI (1.21, 5.98); P=0.003] as well as a significant reduction in systolic pulmonary artery pressure [-6.15; 95% CI (-9.29, -3.02); P=0.0001] and pulmonary vascular resistance [-39.48; 95% CI (-65.59, -13.38); P=0.003], whereas changes in mean pulmonary pressure were nonsignificant. Adverse events did not significantly differ between the two groups. Our study shows that levosimendan exhibits short-term efficacy for treating RHF in patients with a variety of heart and lung diseases. Additional strict multicentre RCTs with long follow-up times and large sample sizes are required to further validate the efficacy and safety of this treatment. Copyright © 2017.

    Re-hospitalization after discharge for acute decompensated heart failure is a common problem. Low-socioeconomic urban patients suffer high rates of re-hospitalization and often over-utilize the emergency department (ED) for their care. We hypothesized that early consultation with a cardiologist in the ED can reduce re-hospitalization and health care costs for low-socioeconomic urban patients with acute decompensated heart failure. There were 392 patients treated at our center for acute decompensated heart failure who received standardized education and follow-up. Patients who returned to the ED received early consultation with a cardiologist; 392 patients who received usual care served as controls. Thirty- and 90-day re-hospitalization, ED re-visits, heart failure symptoms, mortality, and health care costs were recorded. Despite guideline-based education and follow-up, the rate of ED re-visits was not different between the groups. However, the rate of re-hospitalization was significantly lower in patients receiving the intervention compared with controls (odds ratio 0.592), driven by a reduction in the risk of readmission from the ED (0.56 vs 0.79, respectively). Patients receiving the intervention accumulated 14% fewer re-hospitalized days than controls and 57% lower 30-day total health care cost. Despite the reduction in health care resource consumption, mortality was unchanged. After accounting for the total cost of intervention delivery, the health care cost savings was substantially greater than the cost of intervention delivery. Early consultation with a cardiologist in the ED as an adjunct to guideline-based follow-up is associated with reduced re-hospitalization and health care cost for low-socioeconomic urban patients with acute decompensated heart failure.

    Sodium restriction has been believed to be indispensible to manage fluid overload during acute decompensated heart failure (ADHF). However, recently, it was reported that a change in aggression of sodium and water restriction did not affect the outcome of ADHF. In contrast, current data suggest that small amount of hypertonic saline solution with high-dose furosemide produces an improvement in haemodynamic and clinical parameters without any severe adverse effects. In this perspective, first, we are going to describe the effects of sodium loading on neurohormonal activation, body's sodium balance, and renal function in chronic heart failure and the efficacy of loop diuretics in ADHF. Then, we are going to explain the possible mechanisms by which sodium loading enhances the efficacy of loop diuretics and about the clinical conditions during which sodium loading should be avoided. © 2014 The Authors.

    The prevalence of the right heart failure (RHF) is poorly known. However, RHF is often a consequence of left heart failure due to an interdependance between both ventricles. RHF should be indentified because of prognostic relevance. RHF is defined by the inability to maintain adequate cardiac output through the lung circulation. It can result from volume overload, pressure overload, or a disorder of systolic function. Adaptive mechanisms such as dilation or hyper-trophy will maintain adequate hemodynamics. Once these mechanisms become insufficient, congestive signs and hemodynamic consequences will appear. Diagnosis is based on echocardiography. The treatment of RHF is similar to left heart failure. In case of acute RHF, treatment depends of the etiology of RHF. Optimization of the volemia is a central objective of therapeutics.

    Persistent congestion is associated with worse outcomes in acute heart failure (AHF). Mineralocorticoid receptor antagonists administered at high doses may relieve congestion, overcome diuretic resistance, and mitigate the effects of adverse neurohormonal activation in AHF. To assess the effect of high-dose spironolactone and usual care on N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels compared with usual care alone. This double-blind and placebo (or low-dose)-controlled randomized clinical trial was conducted in 22 US acute care hospitals among patients with AHF who were previously receiving no or low-dose (12.5 mg or 25 mg daily) spironolactone and had NT-proBNP levels of 1000 pg/mL or more or B-type natriuretic peptide levels of 250 pg/mL or more, regardless of ejection fraction. High-dose spironolactone (100 mg) vs placebo or 25 mg spironolactone (usual care) daily for 96 hours. The primary end point was the change in NT-proBNP levels from baseline to 96 hours. Secondary end points included the clinical congestion score, dyspnea assessment, net urine output, and net weight change. Safety end points included hyperkalemia and changes in renal function. A total of 360 patients were randomized, of whom the median age was 65 years, 129 (36%) were women, 200 (55.5%) were white, 151 (42%) were black, 8 (2%) were Hispanic or Latino, 9 (2.5%) were of other race/ethnicity, and the median left ventricular ejection fraction was 34%. Baseline median (interquartile range) NT-proBNP levels were 4601 (2697-9596) pg/mL among the group treated with high-dose spironolactone and 3753 (1968-7633) pg/mL among the group who received usual care. There was no significant difference in the log NT-proBNP reduction between the 2 groups (-0.55 [95% CI, -0.92 to -0.18] with high-dose spironolactone and -0.49 [95% CI, -0.98 to -0.14] with usual care, P = .57). None of the secondary end point or day-30 all-cause mortality or heart failure hospitalization rate differed

    Previous studies have identified candidate circulating microRNAs (circmiRs) as biomarkers for heart failure (HF) using relatively insensitive arrays, validated in small cohorts. The present study used RNA sequencing to identify novel candidate circmiRs and compared these with previously identified circmiRs in a large, prospective cohort of patients with acute HF (AHF). RNA sequencing of plasma from instrumented pigs was used to identify circmiRs produced by myocardium. Production of known myomiRs and microRNA (miR)-1306-5p was identified. The prognostic values of this and 11 other circmiRs were tested in a prospective cohort of 496 AHF patients, from whom blood samples were collected at up to seven time-points during the study's 1-year follow-up. The primary endpoint was the composite of all-cause mortality and HF rehospitalization. In the prospective AHF cohort, 188 patients reached the primary endpoint, and higher values of repeatedly measured miR-1306-5p were positively associated with risk for reaching the primary endpoint at the same time-point [hazard ratio (HR) 4.69, 95% confidence interval (CI) 2.18-10.06], independent of clinical characteristics and NT-proBNP. Baseline miR-1306-5p did not improve model discrimination/reclassification significantly compared with NT-proBNP. For miR-320a, miR-378a-3p, miR-423-5p and miR-1254, associations with the primary endpoint were present after adjustment for age and sex (HR 1.38, 95% CI 1.12-1.70; HR 1.35, 95% CI 1.04-1.74; HR 1.45, 95% CI 1.10-1.92; HR 1.22, 95% CI 1.00-1.50, respectively). Rates of detection of myomiRs miR-208a-3p and miR-499a-5p were very low. Repeatedly measured miR-1306-5p was positively associated with adverse clinical outcome in AHF, even after multivariable adjustment including NT-proBNP. However, baseline miR-1306-5p did not add significant discriminatory value to NT-proBNP. Low-abundance, heart-enriched myomiRs are often undetectable, which mandates the development of more sensitive assays.

    The benefits of fluid and sodium restriction in patients hospitalized with acute decompensated heart failure (ADHF) are unclear. To compare the effects of a fluid-restricted (maximum fluid intake, 800 mL/d) and sodium-restricted (maximum dietary intake, 800 mg/d) diet (intervention group [IG]) vs a diet with no such restrictions (control group [CG]) on weight loss and clinical stability during a 3-day period in patients hospitalized with ADHF. Randomized, parallel-group clinical trial with blinded outcome assessments. Emergency room, wards, and intensive care unit. Adult inpatients with ADHF, systolic dysfunction, and a length of stay of 36 hours or less. Fluid restriction (maximum fluid intake, 800 mL/d) and additional sodium restriction (maximum dietary intake, 800 mg/d) were carried out until the seventh hospital day or, in patients whose length of stay was less than 7 days, until discharge. The CG received a standard hospital diet, with liberal fluid and sodium intake. Weight loss and clinical stability at 3-day assessment, daily perception of thirst, and readmissions within 30 days. Seventy-five patients were enrolled (IG, 38; CG, 37). Most were male; ischemic heart disease was the predominant cause of heart failure (17 patients [23%]), and the mean (SD) left ventricular ejection fraction was 26% (8.7%). The groups were homogeneous in terms of baseline characteristics. Weight loss was similar in both groups (between-group difference in variation of 0.25 kg [95% CI, -1.95 to 2.45]; P = .82) as well as change in clinical congestion score (between-group difference in variation of 0.59 points [95% CI, -2.21 to 1.03]; P = .47) at 3 days. Thirst was significantly worse in the IG (5.1 [2.9]) than the CG (3.44 [2.0]) at the end of the study period (between-group difference, 1.66 points; time × group interaction; P = .01). There were no significant between-group differences in the readmission rate at 30 days (IG, 11 patients [29%]; CG, 7 patients [19%]; P = .41

    The European Association of Cardiology (ESC) Guidelines on the diagnosis and treatment of acute heart failure (AHF) indicate prompt therapy initiation and performance of relevant investigations as paramount. Specifically, echocardiography prior to treatment is advocated only with hemodynamic instability, and the evaluation of clinical signs of peripheral perfusion and congestion is suggested as guidance for early interventions. Given the growing body of evidence on the diagnostic/monitoring capabilities of bedside ultrasound (including focused cardiac ultrasound, comprehensive echocardiography, lung ultrasound), we discuss the potential benefit of an integrated clinical/ultrasound approach at the very early stages of acute heart failure. We proposed a narrative review of the current evidence on the clinical-ultrasound integrated approach to AHF, with special emphasis on the components of the early diagnostic-therapeutic workup where cardiac, inferior vena cava and lung ultrasound showed high diagnostic accuracy and the capability of substantially changing an exclusively clinically-oriented patient management. A proactive comment to the ESC guidelines is made, suggesting an integration of clinical and biochemical assessment, as defined by guidelines, with combined bedside ultrasound on may help in the definition of AHF pathophysiology and treatment. A multi-organ integrated clinical-ultrasound approach should be advocated as part of the clinical-diagnostic workup at AHF very early phase. Whenever competence and technology available, bedside ultrasound, along with clinical and biochemical assessment, should target AHF profiling, identify the cause of AHF, and subsequently aid disease course and response to treatment monitoring.

    There are conflicting results among previous studies regarding the prognosis of heart failure with preserved ejection fraction (HFpEF) compared with heart failure with reduced ejection fraction (HFrEF). This study aimed to compare the outcomes of patients with de novo acute heart failure (AHF) or acute decompensated HF (ADHF) according to HFpEF (EF≥50%), or HFrEF (EF<40%) and to define the prognosis of patients with HF with mid-range EF (HFmrEF, 40≤EF<50%). Between March 2011 and February 2014, 5625 consecutive patients with AHF were recruited from 10 university hospitals. A total of 5414 (96.2%) patients with EF data were enrolled, which consisted of 2867 (53.0%) patients with de novo and 2547 (47.0%) with ADHF. Each of the enrolled group was stratified by EF. In de novo, all-cause death rates were not significantly different between HFpEF and HFrEF (HFpEF vs HFrEF, 206/744 (27.7%) vs 438/1631 (26.9%), HR adj 1.15, 95% CI 0.96 to 1.38, p=0.14). However, among patients with ADHF, HFrEF had a significantly higher mortality rate compared with HFpEF (HFpEF vs HFrEF, 245/613 (40.0%) vs 694/1551 (44.7%), HR adj 1.25, 95% CI 1.06 to 1.47, p=0.007). Also, in ADHF, HFmrEF was associated with a significantly lower mortality rate within 1 year compared with HFrEF (HFmrEF vs HFrEF, 88/383 (23.0%) vs 430/1551 (27.7%), HR adj 1.31, 95% CI 1.03 to 1.65, p=0.03), but a significantly higher mortality rate after 1 year compared with HFpEF (HFmrEF vs HFpEF, 83/295 (28.1%) vs 101/469 (21.5%), HR adj 0.70, 95% CI 0.52 to 0.96, p=0.02). HFpEF may indicate a better prognosis compared with HFrEF in ADHF, but not in de novo AHF. For patients with ADHF, the prognosis associated with HFmrEF was similar to that of HFpEF within the first year following hospitalisation and similar to HFrEF 1  year after hospitalisation. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    The acute hemodynamic effects of ibopamine (SB-7505), the 3,4-diisobutyryl ester of N-methyldopamine which can be administered orally, were compared with those of dopamine. Ten male patients aged 54 years on average, with chronic congestive heart failure in NYHA (New York Heart Association) classes II-IV were studied. Eight of them were suffering from idiopathic congestive cardiomyopathy and two from ischemic cardiopathy. Baseline hemodynamic parameters were recorded within 24 h after withdrawal of previous treatment, the patients being kept on digitalis only. The investigation was carried out for a period of 3 days running. On day 1 of treatment one group of 5 patients were given dopamine at increasing doses of 2, 4 and 6 micrograms/kg/min. Their hemodynamic parameters were assessed 15 min after each dose and 15 and 60 min after withdrawal of the drug. Ibopamine was then administered orally in single doses of 50 mg on day 2 and 100 mg on day 3. The hemodynamic parameters were evaluated at 30, 60, 90, 120, 180, 360 and 480 min after administration. On day 1, another group of 5 patients were given 50 mg ibopamine, on day 2, 100 mg ibopamine and on day 3, dopamine. Hemodynamic data in this group of patients were evaluated at the same times mentioned above. The hemodynamic effects of ibopamine 100 mg are very similar to those obtained with 4 micrograms/kg/min dopamine. Indeed, the effects of both drugs on the cardiac index, right atrial pressure, peripheral and pulmonary vascular resistance do not differ significantly from each other.(ABSTRACT TRUNCATED AT 250 WORDS)

    Composite end points are frequently used in clinical trials of investigational treatments for acute heart failure, eg, to boost statistical power and reduce the overall sample size. By incorporating multiple and varying types of clinical outcomes they provide a test for the overall efficacy of the treatment. Our objective is to compare the performance of popular composite end points in terms of statistical power and describe the uncertainty in these power estimates and issues concerning implementation. We consider several composites that incorporate outcomes of varying types (eg, time to event, categorical, and continuous). Data are simulated for 5 outcomes, and the composites are derived and compared. Power is evaluated graphically while varying the size of the treatment effects, thus describing the sensitivity of power to varying circumstances and eventualities such as opposing effects. The average z score offered the most power, although caution should be exercised when opposing effects are anticipated. Results emphasize the importance of an a priori assessment of power and scientific basis for construction, including the weighting of individual outcomes deduced from data simulations. The interpretation of a composite should be made alongside results from the individual components. The average z score offers the most power, but this should be considered in the research context and is not without its limitations. Copyright © 2016 Canadian Cardiovascular Society.

    Natriuretic peptides are a family of peptides with similar structures, but are genetically distinct with diverse actions in cardiovascular, renal and fluid homeostasis. The family consists of an atrial natriuretic peptide (ANP) and a brain natriuretic peptide (BNP) of myocardial cell origin, a C-type natriuretic peptide (CNP) of endothelial origin, and a urodilatin (Uro) which is processed from a prohormone ANP in the kidney. Nesiritide, a human recombinant BNP, was approved by the Federal Drug Administration (FDA) for the management of acute heart failure (AHF) in 2001. Human recombinant ANP (Carperitide) was approved for the same clinical indication in Japan in 1995, and human recombinant Urodilatin (Ularitide) is currently undergoing phase III clinical trial (TRUE AHF). This review will provide an update on important issues regarding the role of BNP in fluid hemostasis as a biomarker and therapeutics in AHF.

    Acute heart failure (AHF) requires considerable use of resources, is an economic burden, and is associated with high complication and mortality rates in emergency departments, on hospital wards, or outpatient care settings. Diagnosis, treatment, and continuity of care are variable at present, leading 3 medical associations (for cardiology, internal medicine, and emergency medicine) to undertake discussions and arrive at a consensus on clinical practice guidelines to support those who manage AHF and encourage standardized decision making. These guidelines, based on a review of the literature and clinical experience with AHF, focus on critical points in the care pathway. Regarding emergency care, the expert participants considered the initial evaluation of patients with signs and symptoms that suggest AHF, the initial diagnosis, first decisions about therapy, monitoring, assessment of prognosis, and referral criteria. For care of the hospitalized patient, the group developed a protocol for essential treatment. Objectives for the management and treatment of AHF on discharge were also covered through the creation or improvement of multidisciplinary care systems to provide continuity of care.

    Previous studies have reported conflicting findings regarding how the incidence of heart failure (HF) after acute myocardial infarction (AMI) has changed over time, and data on contemporary national trends are sparse. Using a complete national sample of 2 789 943 AMI hospitalizations of Medicare fee-for-service beneficiaries from 1998 through 2010, we evaluated annual changes in the incidence of subsequent HF hospitalization and mortality using Poisson and survival analysis models. The number of patients hospitalized for HF within 1 year after AMI declined modestly from 16.1 per 100 person-years in 1998 to 14.2 per 100 person years in 2010 (P1998, which decreased to 43.2% in 2004 to 2005, but then increased to 45.5% by 2010. After adjusting for demographic factors and clinical comorbidities, this represented a 2.4% relative annual decline (hazard ratio, 0.976; 95% confidence interval, 0.974-0.978) from 1998 to 2007, but a 5.1% relative annual increase from 2007 to 2010 (hazard ratio, 1.051; 95% confidence interval, 1.039-1.064). In a national sample of Medicare beneficiaries, HF hospitalization after AMI decreased from 1998 to 2010, which may indicate improvements in the management of AMI. In contrast, survival after HF following AMI remains poor, and has worsened from 2007 to 2010, demonstrating that challenges still remain for the treatment of this high-risk condition after AMI.

    Heart failure (HF) complicating acute myocardial infarction (AMI) is common and is associated with poor clinical outcome. Limited data exist regarding the incidence and in-hospital mortality of AMI with HF (AMI-HF). We retrospectively analyzed 1,427 consecutive patients with AMI in the five major university hospitals in Korea at two time points, 1998 (n = 608) and 2008 (n = 819). Two hundred twenty eight patients (37.5%) in 1998 and 324 patients (39.5%) in 2008 of AMI patients complicated with HF (P = 0.429). AMI-HF patients in 2008 were older, had more hypertension, previous AMI, and lower systolic blood pressure than those in 1998. Regarding treatments, AMI-HF patients in 2008 received more revascularization procedures, more evidence based medical treatment and adjuvant therapy, such as mechanical ventilators, intra-aortic balloon pulsation compared to those in 1998. However, overall in-hospital mortality rates (6.4% vs 11.1%, P = 0.071) of AMI-HF patients were unchanged and still high even after propensity score matching analysis, irrespective of types of AMI and revascularization methods. In conclusion, more evidence-based medical and advanced procedural managements were applied for patients with AMI-HF in 2008 than in 1998. However the incidence and in-hospital mortality of AMI-HF patients were not significantly changed between the two time points.

    More efficacious and/or safer decongestive therapy is clearly needed in acute heart failure (AHF) patients complicated by renal dysfunction. We tested the hypothesis that adding tolvaptan, an oral vasopressin-2 receptor antagonist, to conventional therapy with loop diuretics would be more effective treatment in this population. A multicenter, open-label, randomized control trial was performed, and 217 AHF patients with renal dysfunction (estimated glomerular filtration rate 15-60 mL • min(-1) • 1.73 m(-2)) were randomized 1:1 to treatment with tolvaptan (n=108) or conventional treatment (n=109). The primary end point was 48-hour urine volume. The tolvaptan group showed more diuresis than the conventional treatment group (6464.4 vs 4999.2 mL; P tolvaptan group at all time points within 48 hours except 6 hours after enrollment. The rate of worsening of renal function (≥0.3 mg/dL increase from baseline) was similar between the tolvaptan and conventional treatment groups (24.1% vs 27.8%, respectively; P =.642). Adding tolvaptan to conventional treatment achieved more diuresis and relieved dyspnea symptoms in AHF patients with renal dysfunction.

    [corrected] Acute decompensated heart failure (ADHF) is a common and highly morbid cardiovascular disorder. Diuresis is a major therapy for the reduction of congestive symptoms. However, most diuretics cause hyponatremia, which is a worsening factor of ADHF patients prognosis. The purpose of this study was to examine the efficacy and safety of tolvaptan, which is a selective vasopressin V2 receptor antagonist and produces water excretion without changes in sodium excretion, compared with carperitide. One hundred and nine hospitalized ADHF patients were enrolled and randomly assigned to tolvaptan or carperitide treatment groups. Subjective symptoms and plasma BNP level were similarly improved by treatment in both groups. Urine volume was significantly higher in the tolvaptan group (P tolvaptan group (P tolvaptan group after treatment (P tolvaptan group (P = .027). The average drug cost of tolvaptan was lower than that of carperitide (P Tolvaptan might be a novel promising agent for ADHF in terms of efficacy and safety compared to carperitide. © 2013 The Authors.

    Full Text Available The presence and type of viral genomes have been suggested as the main etiology for inflammatory dilated cardiomyopathy. Information on the clinical implication of this finding in a large population of children is lacking. We evaluated the prevalence, type, and clinical impact of specific viral genomes in endomyocardial biopsies (EMB collected between 2001 and 2013 among 63 children admitted to our hospital for acute heart failure (median age 2.8 years. Viral genome was searched by polymerase chain reaction (PCR. Patients underwent a complete two-dimensional echocardiographic examination at hospital admission and at discharge and were followed-up for 10 years. Twenty-seven adverse events (7 deaths and 20 cardiac transplantations occurred during the follow-up. Viral genome was amplified in 19/63 biopsies (35%; PVB19 was the most commonly isolated virus. Presence of specific viral genome was associated with a significant recovery in ejection fraction, compared to patients without viral evidence (p < 0.05. In Cox-regression analysis, higher survival rate was related to virus-positive biopsies (p < 0.05. When comparing long-term prognosis among different viral groups, a trend towards better prognosis was observed in the presence of isolated Parvovirus B19 (PVB19 (p = 0.07. In our series, presence of a virus-positive EMB (mainly PVB19 was associated with improvement over time in cardiac function and better long-term prognosis.

    Heart failure (HF) is a global public health problem of increasing importance. The association between acute exposure to air pollution and HF has been well established in developed countries, but little evidence was available in developing countries where air pollution levels were much higher. We conducted a time-series study to investigate the short-term association between air pollution and overall emergency ambulance dispatches (EAD) due to HF in Guangzhou, China. Daily data of EAD due to HF from 1 January 2008 to 31 December 2012 were obtained from Guangzhou Emergency Center. We applied the over-dispersed Poisson generalized addictive model to analyze the associations after controlling for the seasonality, day of the week and weather conditions. We identified a total of 3375 EAD for HF. A 10-μg/m(3) increase in the present-day concentrations of particulate matter with an aerodynamic diameter of less than 10 μm, sulfur dioxide and nitrogen dioxide corresponded to increases of 3.54% [95% confidence interval (CI): 1.35%, 5.74%], 5.29% (95% CI: 2.28%, 8.30%) and 4.34% (95% CI: 1.71%, 6.97%) in daily EAD for HF, respectively. The effects of air pollution on acute HF were restricted on the concurrent day and in the cool seasons. Our results provided the first population-based evidence in Mainland China that outdoor air pollution could trigger the exacerbation of HF. Copyright © 2014 Elsevier Ireland Ltd.

    This study sought to evaluate the prognostic effect of carbohydrate antigen-125 (CA125)-guided therapy (CA125 strategy) versus standard of care (SOC) after a hospitalization for acute heart failure (AHF). CA125 has emerged as a surrogate of fluid overload and inflammatory status in AHF. After an episode of AHF admission, elevated values of this marker at baseline as well as its longitudinal profile relate to adverse outcomes, making it a potential tool for treatment guiding. In a prospective multicenter randomized trial, 380 patients discharged for AHF and high CA125 were randomly assigned to the CA125 strategy (n = 187) or SOC (n = 193). The aim in the CA125 strategy was to reduce CA125 to ≤35 U/ml by up or down diuretic dose, enforcing the use of statins, and tightening patient monitoring. The primary endpoint was 1-year composite of death or AHF readmission. Treatment strategies were compared as a time to first event and longitudinally. Patients allocated to the CA125 strategy were more frequently visited, and treated with ambulatory intravenous loop diuretics and statins. Likewise, doses of oral loop diuretics and aldosterone receptor blockers were more frequently modified. The CA125 strategy resulted in a significant reduction of the primary endpoint, whether evaluated as time to first event (66 events vs. 84 events; p = 0.017) or as recurrent events (85 events vs. 165 events; incidence rate ratio: 0.49; 95% confidence interval: 0.28 to 0.82; p = 0.008). The effect was driven by significantly reducing rehospitalizations but not mortality. The CA125 strategy was superior to the SOC in terms of reducing the risk of the composite of 1-year death or AHF readmission. This effect was mainly driven by significantly reducing the rate of rehospitalizations. (Carbohydrate Antigen-125-guided Therapy in Heart Failure [CHANCE-HF]; NCT02008110).

    Full Text Available We report a case of left heart failure caused by a sliding hiatus hernia compressing on left atrium. A 95-year-old woman was admitted with recurrent episodes of shortness of breath and chest pain. The cause was uncertain as she had normal cardiothoracic ratio on chest radiography. Computed tomography (CT of the thorax revealed an intrathoracic mass behind the left atrium causing external compression of the left atrium suggestive of sliding hiatus hernia. We present such a case and possible mechanisms of heart failure.

    The acute hemodynamic effects of combining administration of digoxin (DIG)(0.01 mg/kg intravenously) with molsidomine (MLS)(4 mg sublingually) were compared with those of DIG and MLS considered alone in 12 patients with congestive heart failure following acute myocardial infarction. The patients were classified into two subgroups, A (cardiac index [CI] less than or equal to 2.2 L/min/m2 and B (CI greater than 2.2 L/min/m2), to verify differences between the responses to the three drug regimens. MLS significantly reduced systolic blood pressure from 121.2 +/- 12.3 (mean +/- SD) to 111.7 +/- 10.9 mm Hg (p less than 0.01) after 60 min, mean right atrial pressure (RAP) from 6.2 +/- 3.6 to 2.4 +/- 2.1 mm Hg (p less than 0.0001), mean pulmonary arterial pressure (PAP), left ventricular filling pressure (LVFP) from 20.6 +/- 2.1 to 12.2 +/- 2.8 mm Hg (p less than 0.0001), and pulmonary vascular resistance (PVR). Left ventricular stroke work index (LVSWI) significantly increased after 60 min. DIG induced a significant reduction in heart rate, RAP, PAP, and LVFP from 20.1 +/- 2 to 14.3 +/- 2.7 mm Hg (p less than 0.0001) after 90 min. Stroke volume index (SVI) increased from 24.7 +/- 4.2 to 27.7 +/- 3.1 ml/beat/m2 (p less than 0.001) and LVSWI from 25.9 +/- 7.2 to 31.9 +/- 5.4 g X m/m2 (p less than 0.0001). The combination of DIG and MLS produced a reduction in RAP, PAP, and LVFP greater than that achieved with either agent alone, with a further shift of the ventricular function curve to the left, thereby leading to an improvement in cardiac performance.(ABSTRACT TRUNCATED AT 250 WORDS)

    We investigated the possible cardiac effects of oxygen addition to contrast media (CM) during coronary arteriography in dogs that did and did not have ischemic heart failure. Acute ischemic heart failure was induced by injecting small plastic microspheres into the left coronary artery of 18 dogs. Hemodynamic and electrophysiologic measurements were performed during a single injection before and during heart failure and during a single injection and five rapidly repeated CM injections during heart failure. Iohexol supplemented with electrolytes (iohexol + electrolytes = IPE), oxygenated IPE (IPE+O), Ringer acetate, and oxygenated Ringer acetate were injected into the left coronary artery. Single injections of IPE and IPE+O induced small hemodynamic and electrophysiologic effects. However, repeated injections of IPE and IPE+O increased left ventricular inotropy (maximum value of the first derivative of the left ventricular pressure) by 36% and 39%, reduced heart rate by 7% (for both), and lengthened QTc time (corrected QT interval) by 39 and 38 msec, respectively. A comparison of IPE and IPE+O revealed no statistically significant differences. Although electrolyte addition to nonionic CM may reduce the risk of cardiac complications during coronary arteriography, oxygenation does not seem to significantly further reduce this risk.

    Although intravenous diuretics have been mainstay drugs in patients with acute heart failure (AHF), they have been suggested to have some deleterious effects on prognosis. We postulated that renal function may modify their deleterious effects in AHF patients. The study population consisted of 1094 AHF patients from three hospitals. Renal dysfunction (RD) was defined as estimated glomerular filtration rate (eGFR) renal function in AHF. This association may be one reason for poorer prognosis of AHF patients complicated with renal impairment.

    To determine the cost-effectiveness of natriuretic peptide (NP) testing and specialist outreach in patients with acute heart failure (AHF) residing off the cardiology ward. We used a Markov model to estimate costs and quality-adjusted life-years (QALYs) for patients presenting to hospital with suspected AHF. We examined diagnostic workup with and without the NP test in suspected new cases, and we examined the impact of specialist heart failure outreach in all suspected cases. Inputs for the model were derived from systematic reviews, the UK national heart failure audit, randomized controlled trials, expert consensus from a National Institute for Health and Care Excellence guideline development group, and a national online survey. The main benefit from specialist care (cardiology ward and specialist outreach) was the increased likelihood of discharge on disease-modifying drugs for people with left ventricular systolic dysfunction, which improve mortality and reduce re-admissions due to worsened heart failure (associated with lower utility). Costs included diagnostic investigations, admissions, pharmacological therapy, and follow-up heart failure care. NP testing and specialist outreach are both higher cost, higher QALY, cost-effective strategies (incremental cost-effectiveness ratios of £11,656 and £2,883 per QALY gained, respectively). Combining NP and specialist outreach is the most cost-effective strategy. This result was robust to both univariate deterministic and probabilistic sensitivity analyses. NP testing for the diagnostic workup of new suspected AHF is cost-effective. The use of specialist heart failure outreach for inpatients with AHF residing off the cardiology ward is cost-effective. Both interventions will help improve outcomes for this high-risk group. Copyright © 2017 International Society for Pharmacoeconomics and Outcomes Research (ISPOR). Published by Elsevier Inc.

    Objectives To assess the efficacy of tolvaptan in acute heart failure with hyponatremia using a randomized double-blinded placebo-controlled study design. Background Tolvaptan is a selective vasopressin receptor 2 antagonist. There are no published clinical trials on the utility of tolvaptan in acute heart failure with hyponatremia in the Indian population. Methods After screening and informed consent, 51 HF patients with hyponatremia were randomized using computer-generated randomization sequence to receive placebo or 15 mg of tolvaptan for 5 days along with conventional medical therapy. The patient's perception of dyspnea using Likert score and the plasma sodium was measured at baseline and for the next 4 days. Results There was a mean improvement in sodium concentration by 5 mEq/L (p = 0.001) in patients receiving tolvaptan, whereas no significant improvement was seen in the placebo group (p = 0.33). Significant improvement in Likert score was observed in both the groups (p = 0.001), even though there was no difference between both the groups. Dry mouth and thirst were the most commonly occurring adverse effects observed in both the groups. There were no significant hemodynamic changes with tolvaptan therapy. Conclusion Tolvaptan at a dose of 15 mg is effective in reversing hyponatremia in acute heart failure and may be a suitable option in these patients. PMID:27056648

    Congestion is a primary reason for hospitalization in patients with acute heart failure (AHF). Despite inpatient diuretics and vasodilators targeting decongestion, persistent congestion is present in many AHF patients at discharge and more severe congestion is associated with increased morbidity and mortality. Moreover, hospitalized AHF patients may have renal insufficiency, hyponatremia, or an inadequate response to traditional diuretic therapy despite dose escalation. Current alternative treatment strategies to relieve congestion, such as ultrafiltration, may also result in renal dysfunction to a greater extent than medical therapy in certain AHF populations. Truly novel approaches to volume management would be advantageous to improve dyspnea and clinical outcomes while minimizing the risks of worsening renal function and electrolyte abnormalities. One effective new strategy may be utilization of aquaretic vasopressin antagonists. A member of this class, the oral vasopressin-2 receptor antagonist tolvaptan, provides benefits related to decongestion and symptom relief in AHF patients. Tolvaptan may allow for less intensification of loop diuretic therapy and a lower incidence of worsening renal function during decongestion. In this article, we summarize evidence for decongestion benefits with tolvaptan in AHF and describe the design of the Targeting Acute Congestion With Tolvaptan in Congestive Heart Failure Study (TACTICS) and Study to Evaluate Challenging Responses to Therapy in Congestive Heart Failure (SECRET of CHF) trials. © 2015 American Heart Association, Inc.

    In acute heart failure (AHF) patients, pulmonary oedema and low tissue perfusion may lead to changes in the acid-base balance, which may be associated with worse outcomes. In this prospective nationwide cohort study from 24 academic hospitals, arterial blood gas (ABG) was measured in 1982 AHF patients at hospital admission. Acidosis was defined as pH 7.44. Mortality was stratified according to ABG results. Overall, 19% had acidosis, 37% had normal pH, and 44% had alkalosis. The most common type of acidosis was the mixed type (42%) followed by metabolic acidosis (40%), and the most common type of alkalosis was respiratory alkalosis (58%). At 12 months' follow-up 304 patients (15%) died. Patients with acidosis had higher mortality (acidosis 19.5%, neutral pH 13.7%, alkalosis 14.9%; P = 0.007). In the Cox proportional-hazards regression model, acidosis was a significant predictor of mortality (hazard ratio 1.93; 95% confidence intervals 1.27-2.93) along with N-terminal pro-brain type natriuretic peptide (NT-proBNP), among others. In contrast, alkalosis was not associated with increased mortality. pH had an incremental prognostic value over NT-proBNP (net reclassification improvement 30%; P analysis identified extra patients at increased risk for mortality among patients with an NT-proBNP level less than the median (12-month mortality 17.5% vs. 9.9%; P = 0.009). In high-risk AHF patients, the most common acid-base imbalance is respiratory alkalosis. Acidosis is observed in every fifth patient and is a significant predictor of mortality. pH provides an additional prognostic value and may be used to optimize risk stratification in high-risk AHF patients. © 2015 The Authors.

    Symptoms and signs of heart failure (HF) are the most common reasons for admission to hospital for acute HF (AHF) and are used routinely throughout admission to assess the severity of disease and response to therapy. The data were collected in The Sub-Saharan Africa Survey on Heart Failure (THESUS-HF) study, a prospective, multicenter, observational survey of AHF from 9 countries in sub-Saharan Africa. A total of 1006 patients, ≥12 years of age, hospitalized for AHF were recruited. Symptoms and signs of HF and changes in dyspnea and well-being, relative to admission, were assessed at entry and on days 1, 2, and 7 (or on discharge if earlier) and included oxygen saturation, degree of edema and rales, body weight, and level of orthopnea. The patient determined dyspnea and general well-being, whereas the physician determined symptoms and signs of HF, as well as improvements in vital sign measurement, throughout the admission. After multivariable adjustment, baseline rales and changes to day 7 or discharge in general well-being predicted death or HF hospitalization through day 60, and baseline orthopnea, edema, rales, oxygen saturation, and changes to day 7 or on discharge in respiratory rate and general well-being were predictive of death through day 180. In AHF patients in sub-Saharan Africa, symptoms and signs of HF improve throughout admission, and simple assessments, including edema, rales, oxygen saturation, respiratory rate, and asking the patient about general well-being, are valuable tools in patients' clinical assessment.

    Nearly a third of patients with acute heart failure experience concomitant renal dysfunction. This condition is often associated with increased costs of care, length of hospitalisation and high mortality. Although the clinical impact of chronic kidney disease (CKD) has been well established, the exact clinical significance of worsening renal function (WRF) during the acute and post-hospitalisation phases is not completely understood. Therefore, it is still unclear which of the common laboratory markers are able to identify WRF at an early stage. Recent studies comparing CKD with WRF showed contradictory results; this could depend on a different WRF definition, clinical characteristics, haemodynamic disorders and the presence of prior renal dysfunction in the population enrolled. The current definition of acute cardiorenal syndrome focuses on both the heart and kidney but it lacks precise laboratory marker cut-offs and a specific diagnostic approach. WRF and CKD could represent different pathophysiological mechanisms in the setting of acute heart failure; the traditional view includes reduced cardiac output with systemic and renal vasoconstriction. Nevertheless, it has become a mixed model that encompasses both forward and backward haemodynamic dysfunction. Increased central venous pressure, renal congestion with tubular obliteration, tubulo-glomerular feedback and increased abdominal pressure are all potential additional contributors. The impact of WRF on patients who experience preserved renal function and individuals affected with CKD is currently unknown. Therefore it is extremely important to understand the origins, the clinical significance and the prognostic impact of WRF on CKD. © The European Society of Cardiology 2015.

    Obstructive sleep apnea (OSA) is frequently associated with acute coronary syndrome (ACS). Screening of sleep-disordered breathing (SDB) has not been previously evaluated in ACS within 72 h in intensive care settings and its management could potentially enhance patients' prognosis. This pilot study assessed the feasibility of SDB screening at the early phase of ACS. All consecutive patients admitted to the coronary care unit (CCU) for ACS without acute heart failure underwent one overnight-attended polysomnography (PSG) within 72 h after admission. A telemonitoring (TM) system was set up to remotely monitor the signals and repair faulty sensors. The 27 recordings were analyzed as respiratory polygraphy (RP) and as PSG, and the results were compared. The TM system allowed successful intervention in 48% of recordings, resulting in excellent quality PSG for 89% of cases. The prevalence of SDB [apnea-hypopnea index (AHI) ≥ 15/h] was 82% and mainly consisted of central SDB and periodic breathing, except three patients with OSA. Compared with PSG, RP underestimated AHI, probably due to the poor sleep efficiency, reduction of slow-wave sleep, and alteration of rapid eye movement sleep. An early SDB screening by remote-attended PSG is feasible in ACS patients shortly after admission to CCU. The TM enhanced the quality of PSG. A high prevalence of central SDB was noticed, for which the etiology remains unknown. Further large-scale studies are needed to determine whether central SDB is an incidental finding in early ACS and whether the presence and severity of SDB have a prognostic impact.

    Heart failure (HF) is associated with autonomic dysfunction. Vagus nerve stimulation has been shown to improve cardiac function both in HF patients and animal models of HF. The purpose of this present study is to investigate the effects of ganglionated plexus stimulation (GPS) on HF progression and autonomic remodeling in a canine model of acute HF post-myocardial infarction. Eighteen adult mongrel male dogs were randomized into the control (n=8) and GPS (n=10) groups. All dogs underwent left anterior descending artery ligation followed by 6-hour high-rate (180-220bpm) ventricular pacing to induce acute HF. Transthoracic 2-dimensional echocardiography was performed at different time points. The plasma levels of norepinephrine, B-type natriuretic peptide (BNP) and Ang-II were measured using ELISA kits. C-fos and nerve growth factor (NGF) proteins expressed in the left stellate ganglion as well as GAP43 and TH proteins expressed in the peri-infarct zone were measured using western blot. After 6h of GPS, the left ventricular end-diastolic volume, end-systolic volume and ejection fraction showed no significant differences between the 2 groups, but the interventricular septal thickness at end-systole in the GPS group was significantly higher than that in the control group. The plasma levels of norepinephrine, BNP, Ang-II were increased 1h after myocardial infarction while the increase was attenuated by GPS. The expression of c-fos and NGF proteins in the left stellate ganglion as well as GAP43 and TH proteins in cardiac peri-infarct zone in GPS group were significantly lower than that in control group. GPS inhibits cardiac sympathetic remodeling and attenuates HF progression in canines with acute HF induced by myocardial infarction and ventricular pacing. Copyright © 2017 Elsevier B.V.

    The acute heart failure (AHF) Syndromes International Working Group proposed that dyspnea be assessed under standardized, incrementally provocative maneuvers and called for studies to assess the feasibility of this approach. We sought to assess the feasibility and statistical characteristics of a novel provocative dyspnea severity score (pDS) versus the traditional dyspnea visual analog scale (DVAS) in an AHF trial. At enrollment, 24, 48 and 72hours, 230 ROSE-AHF patients completed a DVAS. Dyspnea was then assessed with 5-point Likert dyspnea scales administered during 4 stages (A: upright-with O2, B: upright-without O2, C: supine-without O2 and D: exercise-without O2). Patients with moderate or less dyspnea were eligible for the next stage. At enrollment, oxygen withdrawal and supine provocation were highly feasible (≥97%), provoking more severe dyspnea (≥1 Likert point) in 24% and 42% of eligible patients, respectively. Exercise provocation had low feasibility with 38% of eligible patients unable to exercise due to factors other than dyspnea. A pDS was constructed from Likert scales during the 3 feasible assessment conditions (A-C). Relative to DVAS, the distribution of the pDS was more skewed with a high "ceiling effect" at enrollment (23%) limiting sensitivity to change. Change in pDS was not related to decongestion or 60-day outcomes. Although oxygen withdrawal and supine provocation are feasible and elicit more severe dyspnea, exercise provocation had unacceptable feasibility in this AHF cohort. The statistical characteristics of a pDS based on feasible provocation measures do not support its potential as a robust dyspnea assessment tool in AHF. Copyright © 2015 Elsevier Inc.

    Dyspnea is a common presenting complaint in the emergency department (ED) and a leading cause of hospitalization in intensive care unit (ICU) and medical wards. Ultrasound (US) has traditionally been considered inadequate to explore the aerated lung. However, in the past 15 years LUS gained broader application, at least in part thanks to the interpretation of the artefacts generated by the interaction of US and lung structures/content. The total reflection of US beam occurring at the pleural level determines the artefactual image of the aerated lung: an homogenous 'foggy-like' picture under the pleural line. As the air content of the lungs decreases due to interstitial imbibition, deposition of collagen or presence of blood, vertical artefacts -arising from the pleural line and moving synchronously with the respiration- called B-lines appear. Multiple and bilateral B-lines identify the alveolar-interstitial syndrome (AIS). The most common cause of AIS is the wet lung: the more the congestion burden, the more the extent of the B-lines, which become confluent until the so-called white lung in case of pulmonary edema. Many studies showed a higher accuracy of LUS in diagnosing acute decompensated heart failure (ADHF) as compared to chest X-ray As recently shown, the integration of LUS to clinical assessment allow to differentiate cardiogenic dyspnea with sensitivity and specificity greater than 95 %. Moreover, LUS can easily detect pleural effusion -frequently present in ADHF-appearing as an anechoic area in the recumbent area of the thorax, delimited inferiorly by the diaphragmatic dome and superiorly by the aerated lung.

    Full Text Available Background : Plasma B-type natriuretic peptide (BNP is the diagnostic tool for acute heart failure (AHF.This natriu­retic peptide level depends on renal function, through renal metabolism and excretion. Therefore we examined the effect ofrenal impairment on plasma BNP level during diagnosis of AHF.Objective: The objective of the study was to assess the effect of renal dysfunction on plasma BNP level and to determine appropriate cutoff value of plasma BNP to diagnose the patients of AHF with renal insufficiency.Methods: This cross sectional analytical study was conducted in the Depart­ment of Biochemistry Bangabandhu Sheikh Mujib Medical University (BSMMU. The study was done among 90 AHF patients selected from cardiology emergency department during the period of July 2012 to June 2013. After enrollment plasma BNP concentration was measured and eGFR was estimated from serum creatinine by the four parameter Modifica­tion of Diet and Renal Disease (MORD equation and then grouped into two groups on the basis of empirical cut off value of eGFR 60 ml/min/1.73 m2Results: In this study a significant negative correlation was found between plasma BNP evel and eGFR (P<0.001 , with higher BNP levels observed as eGFR declined. The optimal BNP cutoff value for diagno­sis of AHF patients with renal insufficiency was 824 pg/ml. At this cutoff level AHF with renal insufficiency could be diagnosed with sensitivity and specificity of 84% and 71 %, respectively.Conclusions: By adjusting the cutoff value, plasma BNP can be used to diagnose AHF with renal insufficiency with an acceptable sensitivity and specificity.

    Increasing age predicts ominous prognosis in heart failure. Age influences the success of therapeutic approaches and interacts with other prognostic predictors. We aimed to study the impact of age in long-term survival in different age strata. Patients were prospectively included in an acute heart failure registry; those with acute coronary syndromes and those with primary valvular disease were excluded. Outcome studied was all-cause mortality. Follow-up was 5 years. A receiver-operating characteristic curve was used to define the age cut-off for 5-year death prediction. A multivariate Cox regression analysis was used to study mortality predictors. Analysis was stratified according to the 75-year-age cut-off. We studied 473 patients. Mean age was 75 ± 12 years, 48.4% were men and 68.7% had reduced ejection fraction. Older patients were more often women, with preserved ejection fraction, history of arterial hypertension and atrial fibrillation; they were discharged in higher NYHA classes and with lower haemoglobin. Older patients were less often discharged with evidence-based heart failure therapy. In 5 years, 339 (71.7%) patients died. Patients aged more than 75 years had a multivariate-adjusted hazard ratio of mortality of 1.87 (95% confidence interval 1.46-2.38). In older patients, there was a 5% mortality increase per each 1-year increase in age; 75 years or less, age had no prognostic impact; and P for interaction (age continuous and age dichotomized) was 0.01. Age is a strong long-term prognostic determinant in acute heart failure. The prognostic impact of age was significantly different between age subgroups: it was an independent predictor of mortality in patients aged more than 75 years and had no impact in those aged 75 years or less.

    Heart failure (HF) remains a major public health problem in western countries, despite the enormous progress in its diagnosis and treatment. Acute and chronic decompensated HF are leading medical causes of hospitalization among people aged over 65 years in European countries, the USA, Australia and New Zealand. However, there have been few studies on acute and chronic decompensated HF and the European Society of Cardiology (ESC) guidelines on this subject have only just been published. To evaluate the overall prevalence of hospitalization due to HF according to its subtypes, comorbidities, and decompensating factors, in the Medical Department of a central teaching hospital in an urban area. We performed a retrospective observational study of patients admitted consecutively to the Medical Department via the emergency room between January and June 2001. Discharge casenotes on 1038 admissions were reviewed. Those with a diagnosis of HF or cardiovascular conditions associated with or precursors of HF were analyzed. Cases with a final diagnosis of HF according to the criteria of the ESC guidelines were included in the study. We evaluated the overall prevalence of HF and subtypes of cardiac dysfunction, etiological risk factors, patients' demographic characteristics, decompensating factors, comorbidity, mean length of hospital stay, and in-hospital mortality rate. We identified 180 patients with HF (17.4%), mean age 74.6 +/- 14; 87 were male (48%), aged 73.7 +/- 14.2, and 93 female (52%), aged 75.6 +/- 14. Left ventricular systolic dysfunction (LVSD) was present in 42.2% of cases, preserved left ventricular systolic function in 32.6%, and valvular heart disease in 10.6%. Hypertension and coronary artery disease were the main etiological risk factors (62.2% and 42.8% respectively). Atrial fibrillation was recorded in 43.4% of the patients, diabetes was diagnosed in 21.6%, and anemia and chronic obstructive pulmonary disease in about one third. Infection, predominantly

    Full Text Available Acute heart failure is a common reason for hospital admission and is usually caused by decreased cardiac output either as a result of an intrinsic cardiac issue or as a result of severe hypertension with elevated afterload. We present a patient with a history of HFrEF who presented with acute heart failure, found to have hypotension requiring Dobutamine support and an elevated systemic vascular resistance requiring Nicardipine drip, with subsequent recovery of cardiac function.

  11. Hyponatremia in heart failure.

    2009-01-01

    Hyponatremia is one of the newer and emerging risk factors for an adverse prognosis in chronic heart failure. Why decreased serum sodium is associated with worse prognosis remains unclear. It may reflect worsening heart failure and the deleterious effects of activation of neurohormones. The mechanism of hyponatremia in heart failure also remains unclear. A relatively greater degree of free-water retention compared to sodium retention is probably the major mechanism. The treatment of significant hyponatremia in heart failure is difficult. The conventional treatments such as fluid restriction, infusion of hypertonic saline, and aggressive diuretic therapies are not usually effective. Vasopressin receptor antagonists have been shown to enhance aquaresis and correct hyponatremia. However, long-term beneficial effects of such treatments in chronic heart failure have not been documented.

    Urapidil is putatively effective for patients with hypertension and acute heart failure, although randomized controlled trials thereon are lacking. We investigated the efficacy and safety of intravenous urapidil relative to that of nitroglycerin in older patients with hypertension and heart failure in a randomized controlled trial. Patients (>60 y) with hypertension and heart failure were randomly assigned to receive intravenous urapidil (n=89) or nitroglycerin (n=91) for 7 days. Hemodynamic parameters, cardiac function, and safety outcomes were compared. Patients in the urapidil group had significantly lower mean systolic blood pressure (110.1±6.5 mm Hg) than those given nitroglycerin (126.4±8.1 mm Hg, p=0.022), without changes in heart rate. Urapidil was associated with improved cardiac function as reflected by lower N terminal-pro B type natriuretic peptide after 7 days (3311.4±546.1 ng/mL vs. 4879.1±325.7 ng/mL, p=0.027) and improved left ventricular ejection fraction (62.2±3.4% vs. 51.0±2.4%, p=0.032). Patients given urapidil had fewer associated adverse events, specifically headache (p=0.025) and tachycardia (p=0.004). The one-month rehospitalization and all-cause mortality rates were similar. Intravenous administration of urapidil, compared with nitroglycerin, was associated with better control of blood pressure and preserved cardiac function, as well as fewer adverse events, for elderly patients with hypertension and acute heart failure.

    Coupled arterial and left ventricular properties are poorly documented in acute heart failure. The aim of this prospective noninvasive study was to document early changes in ventricular-arterial coupling in patients with acutely decompensated HF (ADHF). We studied 19 patients hospitalized for ADHF (age 62 ± 15 years, NYHA class 3 or 4). Patients with shock and sustained arrhythmias were excluded. All the patients received intravenous loop diuretics, and none received intravenous vasodilators or inotropes. Ongoing chronic treatments were maintained. Echocardiography and radial artery tonometry were performed simultaneously on admission and after clinical improvement (day 4 ± 1 after admission). Classical echocardiographic parameters were measured, including stroke volume (SV). End-systolic pressure (Pes) was derived from reconstructed central aortic pressure, and arterial elastance (Ea) was calculated as Ea = Pes/SV. End-systolic LV elastance (Ees) was calculated with the single-beat method. Ventricular-arterial coupling was quantified as the Ea/Ees ratio. Following IV diuretic therapy, mean weight loss was 5 ± 2 kg (P < 0·01) and BNP fell from 1813 (median) (IQR = 1284-2342) to 694 (334-1053) pg/mL (P < 0·01). Ea fell by 29%, from 2·46 (2·05-2·86) to 1·78 (1·55-2·00) mmHg/mL (P < 0·01), while Ees remained unchanged (1·28 (1·05-1·52) to 1·13 (0·92-1·34) mmHg/mL). The Ea/Ees ratio therefore fell, from 2·13 (1·70-2·56) to 1·81 (1·56-2·08) (P < 0·02). An early improvement in ventricular-arterial coupling was observed after diuretic-related decongestive therapy in ADHF patients and was related to a decrease in effective arterial elastance rather than to change in LV contractility. © 2014 Stichting European Society for Clinical Investigation Journal Foundation.

  14. Perioperative acute renal failure.

    2012-02-03

    PURPOSE OF REVIEW: Recent biochemical evidence increasingly implicates inflammatory mechanisms as precipitants of acute renal failure. In this review, we detail some of these pathways together with potential new therapeutic targets. RECENT FINDINGS: Neutrophil gelatinase-associated lipocalin appears to be a sensitive, specific and reliable biomarker of renal injury, which may be predictive of renal outcome in the perioperative setting. For estimation of glomerular filtration rate, cystatin C is superior to creatinine. No drug is definitively effective at preventing postoperative renal failure. Clinical trials of fenoldopam and atrial natriuretic peptide are, at best, equivocal. As with pharmacological preconditioning of the heart, volatile anaesthetic agents appear to offer a protective effect to the subsequently ischaemic kidney. SUMMARY: Although a greatly improved understanding of the pathophysiology of acute renal failure has offered even more therapeutic targets, the maintenance of intravascular euvolaemia and perfusion pressure is most effective at preventing new postoperative acute renal failure. In the future, strategies targeting renal regeneration after injury will use bone marrow-derived stem cells and growth factors such as insulin-like growth factor-1.

    Despite current therapies, acute heart failure (AHF) remains a major public health burden with high rates of in-hospital and post-discharge morbidity and mortality. Carperitide is a recombinantly produced intravenous formulation of human atrial natriuretic peptide that promotes vasodilation with increased salt and water excretion, which leads to reduction of cardiac filling pressures. A previous open-label randomized controlled study showed that carperitide improved long-term cardiovascular mortality and heart failure (HF) hospitalization for patients with AHF, when adding to standard therapy. However, the study was underpowered to detect a difference in mortality because of the small sample size. Low-dose Administration of Carperitide for Acute Heart Failure (LASCAR-AHF) is a multicenter, randomized, open-label, controlled study designed to evaluate the efficacy of intravenous carperitide in hospitalized patients with AHF. Patients hospitalized for AHF will be randomly assigned to receive either intravenous carperitide (0.02 μg/kg/min) in addition to standard treatment or matching standard treatment for 72 h. The primary end point is death or rehospitalization for HF within 2 years. A total of 260 patients will be enrolled between 2013 and 2018. The design of LASCAR-AHF will provide data of whether carperitide reduces the risk of mortality and rehospitalization for HF in selected patients with AHF.

  16. Positive influence of being overweight/obese on long term survival in patients hospitalised due to acute heart failure.

    Full Text Available Obesity is clearly associated with increased morbidity and mortality rates. However, in patients with acute heart failure (AHF, an increased BMI could represent a protective marker. Studies evaluating the "obesity paradox" on a large cohort with long-term follow-up are lacking.Using the AHEAD database (a Czech multi-centre database of patients hospitalised due to AHF, 5057 patients were evaluated; patients with a BMI 25 kg/m2. Data were adjusted by a propensity score for 11 parameters.In the balanced groups, the difference in 30-day mortality was not significant. The long-term mortality of patients with normal weight was higher than for those who were overweight/obese (HR, 1.36; 95% CI, 1.26-1.48; p<0.001. In the balanced dataset, the pattern was similar (1.22; 1.09-1.39; p<0.001. A similar result was found in the balanced dataset of a subgroup of patients with de novo AHF (1.30; 1.11-1.52; p = 0.001, but only a trend in a balanced dataset of patients with acute decompensated heart failure.These data suggest significantly lower long-term mortality in overweight/obese patients with AHF. The results suggest that at present there is no evidence for weight reduction in overweight/obese patients with heart failure, and emphasize the importance of prevention of cardiac cachexia.

    Heart failure is associated with increased risk of osteoporosis. We evaluated the prevalence and predictors of osteoporosis in hospitalized patients with ADHF using quantitative computed tomography. Osteoporosis and vertebral fracture are prevalent in patients with ADHF and exercise capacity independently predicts bone mass and femoral bone geometry. Heart failure is associated with reduced bone mass and increased risk of osteoporotic fractures. However, the prevalence and predictors of osteoporosis in hospitalized patients with acute decompensated heart failure (ADHF) are not well understood. Sixty-five patients (15 postmenopausal females and 50 males) with ADHF were prospectively and consecutively enrolled. After stabilization of heart failure symptoms, quantitative computed tomography for bone mineral density (BMD) and femoral geometry as well as biochemical, echocardiographic, and cardiopulmonary exercise tests were performed. Fifteen postmenopausal female showed a high prevalence of osteoporosis (40%) and vertebral fracture (53%). Among 50 male patients, 12% had osteoporosis and 32% had osteopenia, while vertebral fracture was found in 12%. Lumbar volumetric BMD (vBMD) was significantly lower in ischemic patients than non-ischemic patients (107.9 ± 47.5 vs. 145.4 ± 40.9 mg/cm(3), p = 0.005) in male. Exercise capacity, indicated by peak oxygen consumption (VO2), was significantly associated with lumbar vBMD (r = 0.576, p fracture are prevalent, and exercise capacity independently predicts bone mass and geometry. Given that heart failure patients with reduced exercise capacity carry a substantial increased risk of fracture, proper osteoporosis evaluation is important in these patients.

    Background: Matrix metalloproteinases (MMPs) are a family of enzymes important for the resorption of extracellular matrices, control of vascular remodeling and repair. Increased activity of MMP2 has been demonstrated in heart failure, and in acutely decompensated heart failure (ADHF) a decrease in circulating MMPs has been demonstrated along with successful treatment. Objective: Our aim was to test the influence of spironolactone in MMP2 levels. Methods: Secondary analysis of a prospective, interventional study including 100 patients with ADHF. Fifty patients were non-randomly assigned to spironolactone (100 mg/day) plus standard ADHF therapy (spironolactone group) or standard ADHF therapy alone (control group). Results: Spironolactone group patients were younger and had lower creatinine and urea levels (all p enzimas importantes para a reabsorção da matriz extracelular e controle do remodelamento e da reparação vasculares.

    Full Text Available Hospitals today are facing adjustments to reimbursements from excessive readmission rates. One of the most common and expensive causes of readmissions is exacerbation of a heart failure condition. The objective of this paper was to determine if there was an association between the presence of anemia in patients with acute decompensated heart failure and their readmission rate. Using archival data of 4 hospitals in the Miami area, a sample of 847 inpatients with a diagnostic related group (DRG of HF at discharge was considered. There was a significant association between low hemoglobin values and a high rate of readmissions at 14 days and at 30 days in subjects with normal sodium and creatinine values. For subjects with low sodium and high creatinine values, a higher readmission rate was seen in men with low hemoglobin but not in women. These results support a prospective effort to measure the impact of anemia and its treatment on readmission rates.

    Acute decompensated heart failure (ADHF) is the leading cause of hospitalization worldwide, especially in the elderly, and is associated with a high readmission rate and increased first year mortality. Fluid overload manifested by pulmonary congestion is seen in the majority of patients with ADHF and is believed to be the reason behind most admissions. ADHF is commonly treated with intravenous diuretics aimed to alleviate congestion and restore euvolemia. In fact, current European and American guidelines for heart failure (HF) consider relief of congestion as the first-line therapy in ADHF. Following the same theme of reducing fluid retention, historical approaches have recommended water and salt restriction as an essential non-pharmacological therapy in the management of symptomatic HF. This 'common sense' dietary practice was mainly based on experts' opinions and has been challenged by recent data suggesting that salt or fluid restriction has neutral outcomes in achieving clinical stability and improving signs and symptoms of HF.

    Gender-related differences in clinical phenotype, in-hospital management and prognosis of acute heart failure (AHF) patients have been previously reported in European and US registries. The ALARM-HF survey is the first to include a cohort of 4953 patients hospitalized for AHF in 666 hospitals in 6 European countries, Mexico and Australia. Women accounted for 37% of the study population, were older and had higher rates of de novo heart failure (45% vs 36%, pacute coronary syndrome (ACS) was the predominant precipitating factor in both genders, but to a lesser extent in females (30% vs 42%, pvalvular heart disease, diabetes, obesity, anemia and depression in women (pdisease, renal failure and chronic obstructive pulmonary disease (p1.5mg/dL and diabetes. Furthermore, recent ACS, valvular heart disease and dementia contributed to prognosis in women, while LVEF, hypertension and anemia were independent predictors in men. Among patients with AHF, there are significant differences in co-morbidities, precipitating factors and predictors of in-hospital mortality between genders. Nevertheless, in-hospital mortality remains similar between genders. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

    Prognostic scales are needed in acute exacerbation of chronic heart failure to detect early mortality. The objective of this study is to create a prognostic scale (scale EAHFE-3D) to stratify the risk of death the very short term. We used the EAHFE database, a multipurpose, multicenter registry with prospective follow-up currently including 6,597 patients with acute heart failure attended at 34 Spanish Emergency Departments from 2007 to 2014. The following variables were collected: demographic, personal history, data of acute episode and 3-day mortality. The derivation cohort included patients recruited during 2009 and 2011 EAHFE registry spots (n=3,640). The classifying variable was all-cause 3-day mortality. A prognostic scale (3D-EAHFE scale) with the results of the multivariate analysis based on the weight of the OR was created. The 3D-EAHFE scale was validated using the cohort of patients included in 2014 spot (n=2,957). A total of 3,640 patients were used in the derivation cohort and 102 (2.8%) died at 3 days. The final scale contained the following variables (maximum 165 points): age≥75 years (30 points), baseline NYHA III-IV (15 points), systolic blood pressure80 points), with a mortality (derivation/validation cohorts) of 0/0.5, 0.8/1.0, 2.9/2.8, 5.5/5.8 and 12.7/22.4%, respectively. EAHFE-3D scale may help to predict the very short term prognosis of patients with acute heart failure in 5 risk groups. Copyright © 2015 Elsevier España, S.L.U. y SEMICYUC. All rights reserved.

    Diabetes impairs copper (Cu) regulation, causing elevated serum Cu and urinary Cu excretion in patients with established cardiovascular disease; it also causes cardiomyopathy and chronic cardiac impairment linked to defective Cu homeostasis in rats. However, the mechanisms that link impaired Cu regulation to cardiac dysfunction in diabetes are incompletely understood. Chronic treatment with triethylenetetramine (TETA), a Cu²⁺-selective chelator, improves cardiac function in diabetic patients, and in rats with heart disease; the latter displayed ∼3-fold elevations in free Cu²⁺ in the coronary effluent when TETA was infused into their coronary arteries. To further study the nature of defective cardiac Cu regulation in diabetes, we employed an isolated-perfused, working-heart model in which we infused micromolar doses of Cu²⁺ into the coronary arteries and measured acute effects on cardiac function in diabetic and non-diabetic-control rats. Infusion of CuCl₂ solutions caused acute dose-dependent cardiac dysfunction in normal hearts. Several measures of baseline cardiac function were impaired in diabetic hearts, and these defects were exacerbated by low-micromolar Cu²⁺ infusion. The response to infused Cu²⁺ was augmented in diabetic hearts, which became defective at lower infusion levels and underwent complete pump failure (cardiac output = 0 ml/min) more often (P hearts. To our knowledge, this is the first report describing the acute effects on cardiac function of pathophysiological elevations in coronary Cu²⁺. The effects of Cu²⁺ infusion occur within minutes in both control and diabetic hearts, which suggests that they are not due to remodelling. Heightened sensitivity to the acute effects of small elevations in Cu²⁺ could contribute substantively to impaired cardiac function in patients with diabetes and is thus identified as a new mechanism of heart disease.

    Use of intravenous furosemide rather than oral administration in acute decompensated congestive cardiac failure is universally recommended in international guidelines. We argue that this recommendation is not supported by the existing evidence, and suggest that trials should be performed to determine whether larger doses of oral furosemide should be prescribed prior to an IV switch. This could reduce length of hospital admissions and allow for more patients to be managed in the primary care setting. © 2015 ASCPT.

    Elevated plasma concentrations of liver function tests are prevalent in patients with chronic heart failure (HF). Little is known about liver function in patients with acute HF. We aimed to assess the prevalence and prognostic value of serial measurements of liver function tests in patients admitted with acute decompensated HF. We investigated liver function tests from all 234 patients from the Relaxin for the Treatment of Patients With Acute Heart Failure study at baseline and during hospitalization. The end points were worsening HF through day 5, 60-day mortality or rehospitalization, and 180-day mortality. Mean age was 70 ± 10 years, 56% were male, and most patients were in New York Heart Association functional class III/IV (73%). Abnormal liver function tests were frequently found for alanine transaminase (ALT; 12%), aspartate transaminase (AST; 21%), alkaline phosphatase (12%), and total bilirubin (19%), and serum albumin (25%) and total protein (9%) were decreased. In-hospital changes were very small. On a continuous scale, baseline ALT and AST were associated with 180-day mortality (hazard ratios [HRs; per doubling] 1.52 [P = .030] and 1.97 [P = .013], respectively) and worsening HF through day 5 (HRs [per doubling] 1.72 [P = .005] and 1.95 [P = .008], respectively). Albumin was associated with 180-day mortality (HR 0.86; P = .001) but not with worsening HF (HR 0.95; P = .248). Total protein was associated with only worsening HF (HR 0.91; P = .004). Abnormal liver function tests are often present in patients with acute HF and are associated with an increased risk for mortality, rehospitalization, and in-hospital worsening HF.

    Galectin-3 has been reported as a mediator of heart failure (HF) development and progression. Most studies, however, have been conducted on patients with chronic HF rather than acute HF (AHF). The aim of this study was to confirm galectin-3 as a prognostic marker in subjects with AHF and to investigate its possible relationship with left ventricular (LV) remodeling. A total of 69 patients hospitalized with a primary diagnosis of AHF were followed up for 18 months. Galectin-3 and echocardiographic parameters were measured at baseline and after 6 months. Survival analysis and exploratory analysis of LV remodeling were performed. Patients with high baseline galectin-3 values (>16.5 ng/ml) had a significantly worse survival profile over the 18-month follow-up (log-rank test, p = 0.017), with Cox proportional hazards modeling showing a crude hazard ratio (HR) of 4.66 (95% CI = 1.16-18.67; likelihood-ratio test, p = 0.037) for all-cause mortality. Changes in galectin-3 levels (1 SD increase over 6 months) proved to be a significant explanatory factor for HF hospital re-admission in the short term when compared with quasi-stationary galectin-3 levels: worse Kaplan-Meier survival curves (log-rank test, p = 0.001) and a crude HR of 4.44 (95% CI = 1.76-11.18; likelihood-ratio test, p = 0.004). A significant association was found between the pathological evolution of relative wall thickness, LV end-diastolic diameter, LV end-diastolic volume, and increasing levels of galectin-3 in the short term (Cochran-Mantel-Haenszel test, p < 0.01). Galectin-3 can predict long-term mortality in patients with AHF. The results of our study suggest a possible relation between left ventricular remodeling and increasing galectin-3 levels.

    The aim of this study was to analyze the dynamic changes in renal function in combination with dynamic changes in N-terminal pro-B-type natriuretic peptide (NT-proBNP) in patients hospitalized for acute decompensated heart failure (ADHF). Treatment of ADHF improves cardiac parameters, as reflected by lower levels of NT-proBNP. However this often comes at the cost of worsening renal parameters (e.g., serum creatinine, estimated glomerular filtration rate [eGFR], or serum urea). Both the cardiac and renal markers are validated indicators of prognosis, but it is not yet clear whether the benefits of lowering NT-proBNP are outweighed by the concomitant worsening of renal parameters. This study was an individual patient data analysis assembled from 6 prospective cohorts consisting of 1,232 patients hospitalized for ADHF. Endpoints were all-cause mortality and the composite of all-cause mortality and/or readmission for a cardiovascular reason within 180 days after discharge. A significant reduction in NT-proBNP was not associated with worsening of renal function (WRF) or severe WRF (sWRF). A reduction of NT-proBNP of more than 30% during hospitalization determined prognosis (all-cause mortality hazard ratio [HR]: 1.81; 95% confidence Interval [CI]: 1.32 to 2.50; composite endpoint: HR: 1.36, 95% CI: 1.13 to 1.64), regardless of changes in renal function and other clinical variables. When we defined prognosis, NT-proBNP changes during hospitalization for treatment of ADHF prevailed over parameters for worsening renal function. Severe WRF is a measure of prognosis, but is of lesser value than, and independent of the prognostic changes induced by adequate NT-proBNP reduction. This suggests that in ADHF patients it may be warranted to strive for an optimal decrease in NT-proBNP, even if this induces WRF. Copyright © 2015 American College of Cardiology Foundation.

    To analyse the changes in epidemiology, outpatient and emergency department clinical care, and outcomes of patients treated for acute heart failure (AHF) in Spanish hospital emergency departments (HEDs) between 2007 and 2014. A multicentre cohort study was conducted that consecutively included patients with AHF diagnosed in 9HEDs during 4 periods (2007, 2009, 2011 and 2014). The study analysed the changes observed in 20 variables corresponding to baseline data, outpatient care and emergency care data and outcome data. A total of 4,845 patients were included. There were significant changes in 13 variables: there was an increase in patients older than 80years (2007/2014: 45.9%/55.4%; P<.001) and a decrease in severe functional dependence (28.2%/19.7%; P<.001). In terms of long-term outpatient care, there was an increased use of beta-blockers (44.6%/57.8%; P=.002) and aldosterone antagonists (26.6%/37.7%; P<.05) among patients with reduced ejection fraction and an increase use of echocardiography (42.8%/56.2%; P=.001). The use of digoxin decreased (25.4%/16.9%; P=.005). In terms of emergency care, there was an increase in requests for troponins (54.6%/61.9%; P<.001), natriuretic peptides (7.8%/48.5%; P<.001) and the use of noninvasive ventilation (3.2%/6.9%; P=.004). Requests for endovenous perfusion drugs decreased (diuretics: 21.3%/10.4%; P<.001; nitrates: 21.3%/17.5%; P=.001; vasopressors: 4.2%/1.5%; P<.001). Finally, discharges directly from the emergency department without hospitalization increased (20.0%/25.9%; P<.001), and emergency department readmissions at 30days decreased (27.3%/17.6%; P=.007). Hospital mortality and mortality at 30days did not change. Changes in outcomes were detected during a 7-year period in patients with AHF treated in HEDs, with care that was more in line with the clinical guidelines. There are, however, areas for improvement. There was a noteworthy increase in outpatient follow-up without hospitalisation and a reduction in HED

    To identify factors associated with short hospital stays for patients admitted with acute heart failure (AHF) admitted to hospitals with short-stay units (SSU). Multicenter nonintervention study in a multipurpose cohort of patients with AHF to 10 Spanish hospitals with short-stay units; patients were followed prospectively. We recorded demographic data, medical histories, baseline cardiorespiratory and function variables on arrival in the emergency department, on admission, and at 30 days. The outcome variable was a short hospital stay (<= 4 days). We built receiver operating characteristic curves of simple and mixed predictive models for short stays and calculated the area under the curves. A total of 1359 patients with a mean (SD) age of 78.7 (9.9) years (53.9% women) were included; 568 (41.8%) had short stays. Five hundred ninety patients (43.4%) were admitted to SSU and 769 (56.6%) were admitted to conventional wards. The variables associated with a short-stay according to the mixed regression model were hypertensive crisis (odds ratio [OR], 1.79; 95% CI, 1.17-2.73; P=.007) and admission to a SSU (OR, 16.6; 95% CI, 10.0-33.3; P<.001). Hypotensive AHF (OR, 0.49; 95% CI, 0.26-0.91; P=.025), hypoxemia (OR, 0.68; 95% CI, 0.53-0.88; P=.004); and admission on a Wednesday, Thursday, or Friday (OR, 0.62; 95% CI, 0.49-0.77; P<.001) were associated with a long stay. The area under the receiver operating characteristic curve was 0.827 (95% CI, 0.80-0.85; P<.001). Thirty-day mortality and readmission rates did not differ between patients with short vs long stays (mortality, 0.5% in both cases, P=.959; and readmission, 22.9% vs 27.7%, respectively; P=.059). Both clinical and administrative factors are independently related to whether patients with AHF have short stays in the hospitals studied, and among therapy, it is remaslcasle the existence of a SSU.

  14. Lungs in Heart Failure

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available Lung function abnormalities both at rest and during exercise are frequently observed in patients with chronic heart failure, also in the absence of respiratory disease. Alterations of respiratory mechanics and of gas exchange capacity are strictly related to heart failure. Severe heart failure patients often show a restrictive respiratory pattern, secondary to heart enlargement and increased lung fluids, and impairment of alveolar-capillary gas diffusion, mainly due to an increased resistance to molecular diffusion across the alveolar capillary membrane. Reduced gas diffusion contributes to exercise intolerance and to a worse prognosis. Cardiopulmonary exercise test is considered the “gold standard” when studying the cardiovascular, pulmonary, and metabolic adaptations to exercise in cardiac patients. During exercise, hyperventilation and consequent reduction of ventilation efficiency are often observed in heart failure patients, resulting in an increased slope of ventilation/carbon dioxide (VE/VCO2 relationship. Ventilatory efficiency is as strong prognostic and an important stratification marker. This paper describes the pulmonary abnormalities at rest and during exercise in the patients with heart failure, highlighting the principal diagnostic tools for evaluation of lungs function, the possible pharmacological interventions, and the parameters that could be useful in prognostic assessment of heart failure patients.

    The course of patients following admission for acute heart failure (AHF) is of major importance to patients and healthcare providers. We examined predictors and associations of length of stay (LOS), 30-day post-discharge readmission and 90-day post-discharge mortality in 1990 patients enrolled in the PROTECT study. PROTECT was a randomized study that examined the effect of the adenosine blocker rolofylline in patients within 24 h of admission for AHF with mild to moderate renal impairment. Geographic-region-adjusted multivariable models showed that LOS was only partly explained by the severity of heart failure (HF), comorbidities (diabetes mellitus, renal impairment, ischaemic heart disease) and degree of metabolic dysfunction (cholesterol and albumin) at baseline (adjusted R(2) 0.27). Addition of in-hospital worsening heart failure (WHF) and changes in metabolic markers contributed significantly to prediction of LOS [R(2) difference 0.050, 95% confidence interval (CI) 0.0282-0.072]. Thirty-day HF readmission was associated with more severe HF and previous HF admission but not with LOS (odds ratios 1.00, 95% CI 0.97-1.04). Death within 90 days after discharge was associated with older age, more severe HF, worse renal function, and lower sodium and bicarbonate at admission; LOS was a strong predictor of 90-day post-discharge mortality. In patients admitted for AHF, LOS is not well-predicted by traditional markers of disease severity, but strongly associated with the occurrence of in-hospital WHF. Longer LOS is a strong predictor of early mortality after discharge but not of readmission. These findings may help focus efforts to reduce LOS and post-discharge outcomes on patients' subgroups at increased risk. © 2016 The Authors.

    Heart failure (HF) has a poor prognosis. Patients with acute heart failure in particular have a high risk of dying. However, there is a lack of data regarding their long-term mortality and changes there-in with time. The aim of our study was to describe trends in short- and long-term mortality of patients hospitalized with acute HF in the period from 1985 through 2008. In addition, we determined the prognostic worth of the aetiology of HF. We included a consecutive series of 1810 patients with acute HF in this prospective registry in the period of 1985 through 2008. The cumulative one-year mortality rate of the patients was 35%. The short-term prognosis remained unchanged over the decades. However, the cumulative mortality rate ten years after admission was lowest in the last decade (73% in 2000-2008 vs. 78% in 1985-1999, p=0.001). After multivariable adjustment, the ten-year mortality rate was lower in the last decade as compared to the first decade (hazard ratio (HR) 0.83; 95% confidence interval (CI) 0.71-0.96). Ischemic cardiomyopathy was associated with a higher mortality (HR 1.32; 95% CI 1.12-1.54) when compared to other causes of HF. Patients admitted with acute HF were found to have both high short-term and long-term mortality. Long-term prognostic improvement in the last decade was observed among patients with a reduced ejection fraction. While patients with HF due to valvular heart disease had the best prognosis, an ischemic aetiology of HF was associated with the worst outcome. Copyright © 2016 Elsevier Ireland Ltd.

    Hypoalbuminemia is common in patients with chronic heart failure and, as a marker of disease severity, is associated with an adverse prognosis. Whether hypoalbuminemia contributes to (or is associated with) worse outcomes in acute heart failure (AHF) is unclear. We sought to determine the implications of low serum albumin in patients receiving decongestive therapies for AHF. Baseline serum albumin levels were measured in 456 AHF subjects randomized in the DOSE-AHF and ROSE-AHF trials. We assessed the relationship between admission albumin levels (both as a continuous variable and stratified by median albumin [≥3.5 g/dL]) and worsening renal function (WRF), worsening heart failure (WHF), and clinical decongestion by 72 hours; 7-day cardiorenal biomarkers; and post-discharge outcomes. The mean baseline albumin level was 3.5 ± 0.5 g/dL. Albumin was not associated with WRF, WHF, or clinical decongestion by 72 hours. Furthermore, there was no association between continuous albumin levels and symptom change according to visual analog scale or weight change by 72 hours. Albumin was not associated with 60-day mortality, rehospitalization, or unscheduled emergency room visits. Baseline serum albumin levels were not associated with short-term clinical outcomes for AHF patients undergoing decongestive therapies. These data suggest that serum albumin may not be a helpful tool to guide decongestion strategies. Copyright © 2016 Elsevier Inc. All rights reserved.

    To evaluate the differences by sex in clinic presentation, diagnostic approach and initial treatment in patients with acute heart failure who are attended in emergency rooms. Prospective, evaluated, descriptive, transverse and multicentric study, which includes all patients attended by acute heart failure in emergency rooms of 10 Spanish centers between April 15th and May 15th, 2007 (n=944). Data were recorded regarding socio-demographic, comorbidity, previous heart disease, complementary explorations, previous home treatment, and therapeutic measurements in emergency. Regarding men, women (n=501; 53%) were older (79+/-9 and 75+/-10, P<.001), and had more hypertension (83,4% vs 74,9%, P<.01), valvular heart disease (23,1% vs 17,8%, P<.05) and obesity (21,9% vs 15,6%, P<.05); however, they also had less prevalence of coronary heart disease (26,5% vs 43,3%, P=.001) and smoking (4,4 % vs 18,7%, P<.001). According to outpatient treatment, women were less likely to be treated with beta blockers (19,6% vs 30,2%, P<.001) and antithrombotics (34,1% vs 41,3%, P<.05). Treatment administered in the emergency was similar in both groups, yet women received more frequently digoxin (25,7% vs 17,4%, P<.01). Moreover, women were admitted to the cardiology department less often (8,0% vs 13,8%, P<.01). In emergency, the diagnostic and therapeutic approach is very similar in both sexes and the most cases, differences can be justified due to the different patients' profile and the ambulatory handling before their consultation to emergency.

  3. Arrhythmias in Heart Failure.

    Cardiac arrhythmias are very common in the setting of heart failure, with atrial and ventricular arrhythmias often present in the same patient. The risk and the benefit of antiarrhythmic therapies are still a matter of debate. Class I antiarrhythmic drugs should be avoided in patients with heart failure, cardiac ischemia, or previous myocardial infarction. Beta-blocker agents reduce morbidity and decrease mortality in patients suffering from moderate to severe heart failure. Amiodarone may be beneficial in patients with advanced heart failure and increased resting heart rates. This class III drug may be effective to suppress episodes of atrial fibrillation but can also be beneficial in reducing ventricular response by slowing atrioventricular conduction during chronic atrial fibrillation. Implantable cardioverter-defibrillators (ICDs) markedly reduce sudden cardiac death in patients with ventricular tachycardia or ventricular fibrillation. In patients with advanced heart failure, however, the ICD may not markedly extend survival. Recently analyzed data from the Canadian Implantable Defibrillator Study (CIDS), Antiarrhythmics Versus Implantable Defibrillators (AVID) registry, Multicenter Unsustained Tachycardia Trial (MUSTT), and Multicenter Automatic Defibrillator Implantation Trial (MADIT) have consistently shown that it is the sickest patient who benefits the most from ICD therapy. Patients with markedly depressed ejection fraction (death will translate into a reduction of all-cause mortality. For patients resuscitated from sustained ventricular tachycardia or ventricular fibrillation, an ICD or, in some cases, amiodarone should be considered. Catheter or surgical ablation can be considered for selected patients with ventricular tachycardia.

    2017-06-01

    Multiorgan ultrasound (US), which includes evaluation of the lungs and heart, is an accurate method that outperforms clinical gestalt for diagnosing acutely decompensated heart failure (ADHF). A known barrier to ultrasound use is the time needed to perform these examinations. The primary goal of this study was to determine the test characteristics of a modified lung and cardiac US (LuCUS) protocol for the accurate diagnosis of ADHF. This was a secondary analysis of a prospective observational study that enrolled adult patients presenting to the emergency department with undifferentiated dyspnea. Intervention consisted of a modified LuCUS protocol performed by experienced emergency physician sonographers. A positive modified LuCUS protocol was defined as the presence of B+ lines in both the left and right anterosuperior lung zones, plus a left ventricular ejection fraction investigation of the full LuCUS protocol, was 100% for the diagnosis of ADHF.

    Periodic leg movements during sleep (PLM) are characterized by regularly recurring movement of the legs during sleep. Although PLM is common and a predictor of death in patients with chronic heart failure, the clinical significance of PLM in hospitalized patients with a reduced left ventricular ejection fraction (LVEF) following acute decompensated heart failure (ADHF) remains unknown.Methods and Results:After initial improvement of acute signs and symptoms of ADHF, 94 consecutive patients with reduced LVEF who underwent polysomnography were enrolled. They were divided into 2 groups based on the presence or absence of severe PLM defined as PLM index ≥30. The risks for clinical events, composite of all-cause death and rehospitalization, were assessed using a stepwise multivariable Cox proportional model including variables showing PPLM was observed in 21 patients (22%). At a median follow-up of 5.2 months, 30 patients experienced clinical events (32%). In the multivariable analysis, the presence of severe PLM was significantly associated with increasing clinical events (hazard ratio, 2.16; 95% confidence interval, 1.03-4.54; P=0.042) independent of hemoglobin level and the severity of sleep-disordered breathing. In hospitalized patients with systolic dysfunction following ADHF, severe PLM was prevalent and significantly associated with increased risk of death and/or rehospitalization.

    The aim of this study was to evaluate the ability of Neutrophil Gelatinase-Associated Lipocalin (NGAL) to predict clinically relevant worsening renal function (WRF) in acute heart failure (AHF). Plasma NGAL and serum creatinine changes during the first 4 days of admission were investigated in 1447 patients hospitalized for AHF and enrolled in the Placebo-Controlled Randomized Study of the Selective A₁Adenosine Receptor Antagonist Rolofylline for Patients Hospitalized with Acute Decompensated Heart Failure and Volume Overload to Assess Treatment Effect on Congestion and Renal Function (PROTECT) study. WRF was defined as serum creatinine rise ≥ 0.3 mg/dL through day 4. Biomarker patterns were described using linear mixed models. WRF developed in 325 patients (22%). Plasma NGAL did not rise earlier than creatinine in patients with WRF. After multivariable adjustment, baseline plasma NGAL, but not creatinine, predicted WRF. AUCs for WRF prediction were modest (renal or cardiovascular rehospitalization by 60 days than patients with WRF and a low baseline plasma NGAL (p for interaction = 0.024). A rise in plasma NGAL after baseline was associated with a worse outcome in patients with WRF, but not in patients without WRF ( p = 0.007). On the basis of these results, plasma NGAL does not provide additional, clinically relevant information about the occurrence of WRF in patients with AHF.

    Congestive heart failure is a significant cause of morbidity and mortality in Australia. Accurate data for the Northern Territory and Indigenous Australians are not presently available. The economic burden of this chronic cardiovascular disease is felt by all funding bodies and it still remains unclear what impact current measures have on preventing the ongoing disease burden and how much of this filters down to more remote areas. Clear differentials also exist in rural areas including a larger Indigenous community, greater disease burden, differing aetiologies for heart failure as well as service and infrastructure discrepancies. It is becoming increasingly clear that urban solutions will not affect regional outcomes. To understand regional issues relevant to heart failure management, an understanding of the key performance indicators in that setting is critical. The Northern Territory Heart Failure Initiative-Clinical Audit (NTHFI-CA) is a prospective registry of acute heart failure admissions over a 12-month period across the two main Northern Territory tertiary hospitals. The study collects information across six domains and five dimensions of healthcare.

    Ripley, Toni L; Chonlahan, Jennifer S; Germany, Robin E

    2006-01-01

    Candesartan cilexetil is a nonpeptide selective blocker of the angiotensin II receptor sub-type 1. It is a prodrug that is converted to its active metabolite during its variable absorption. It is highly protein bound with a small volume of distribution and a nine-hour half-life. Candesartan is one of two angiotensin receptor blockers approved for use in heart failure. MEDLINE was searched using OVID and PubMed to evaluate the evidence for using candesartan in patients with heart failure. Pharmacologic and pharmacokinetic evaluations, as well as clinical trials, were selected and are presented in this review. Clinical evidence supports the indication for use in systolic heart failure. Results for use in patients with diastolic heart failure were non-significant. Candesartan was well tolerated in the trials, with hyperkalemia, renal dysfunction, and hypotension being the most common adverse events. Use of angiotensin receptor blockers with angiotensin-converting enzyme inhibitors needs further study; however, candesartan appears to provide added benefit in this setting. Candesartan is a safe and effective option for patients with systolic heart failure. Data regarding other angiotensin receptor blockers is underway. PMID:18046913

    In a recent randomized trial, inpatient palliative care (PC) visits were associated with improved quality of life and symptom burden for patients with heart failure. To better understand what actions by PC providers may have led to those outcomes, we conducted chart reviews of 101 patients in the intervention group (who received PC). Palliative care actions are described for all patients and for those with higher symptoms. Orders were written for 24% of patients, most frequently for pain. Recommendations to change current care were made for 40% of patients. At least 1 element of future care planning was documented for 99% of patients. Palliative care for inpatients with HF led to additive actions beyond standard care, especially for pain, and promoted HF-specific goals of care discussions. © The Author(s) 2015.

    We aimed to compare the precipitants of acute decompensated heart failure (ADHF) among patients admitted with diagnoses inclusive of ADHF (community patients) and patients admitted without ADHF but who developed it during their stay (hospital patients). This was a prospective, analytical, observational study undertaken in the Austin Hospital, a major metropolitan teaching hospital (September 2008-February 2010). Consecutive patients admitted to a general medicine unit, and diagnosed and treated for ADHF were enrolled. The unit medical staff completed a specifically designed data collection document. Three hundred and fifty-nine patients were enrolled (42.9% male, mean age 81.9 years). The community (n=312) and hospital (n=47) patient groups did not differ in age, gender, risk variables (living alone, cognitive impairment, multiple medications, compliance), cardiac failure medication use or cause of known heart failure (ischaemia, hypertension, valve dysfunction, 'other') (p>0.05). The ADHF precipitants comprised infection (39.8% patients), myocardial ischaemia (17.3%), tachyarrhythmia (16.2%), non-compliance with fluid and salt restriction (9.2%), non-compliance with medication (6.7%), renal failure (5.8%), medication reduction (5.0%), intravenous fluid complication (3.9%) and 'other' causes (13.9%). Significantly more hospital patients had their ADHF precipitated by intravenous fluid complications (25.5% versus 0.6%, pheart failure precipitated in hospital is a dangerous condition with a high mortality. While infection and myocardial ischaemia are the common precipitants, complications of intravenous fluid use, an iatrogenic condition, may be considerable and are potentially avoidable.

    Compensatory mechanisms activated after myocardial infarction include an increase in systolic wall stress (SWS) and activation of the neurohormonal system. Nevertheless, left ventricular ejection fraction (LVEF) and infarct size are the established primary predictors of outcome after ST-segment elevation myocardial infarction. To assess the relative impact of various cardiac magnetic resonance (CMR) imaging variables, such as infarct size, LVEF and SWS, on pre- and post-discharge heart failure (HF). CMR was performed in a prospective study involving 169 patients with first ST-segment elevation myocardial infarction. Common CMR findings, such as SWS, were computed. Mean SWS was 16.3±5.1×10(3)N·m(-2), and was systematically higher in patients exhibiting either pre- or post-discharge HF (18.9±5.7 and 21.3±7.6×10(3) N·m(-2), respectively). SWS was moderately related to initial infarct size (r=0.405; P <0.001). In total, 28 patients presented with HF during the hospitalization phase and 14 during follow-up, with a median time of event of 93 days (25th-75th percentiles, 29-139.25 days). The univariate predictors of HF were age, LVEF, infarct size, SWS, microvascular obstruction, anterior infarction and heart rate at admission. Multivariable analysis revealed infarct size and age to be the predictors of predischarge HF, while SWS and heart rate at admission predicted post-discharge HF. The greatest SWS quartile provided a negative predictive value of 95.9%. Regardless of LVEF and infarct size, SWS was shown to be an independent predictor of post-discharge HF after ST-segment elevation myocardial infarction. Copyright © 2015 Elsevier Masson SAS.

    The purpose of this trial is to evaluate the effectiveness and safety of electroacupuncture in the treatment of acute decompensated heart failure compared with sham electroacupuncture. This protocol is for a randomized, sham controlled, patient- and assessor-blinded, parallel group, single center clinical trial that can overcome the limitations of previous trials examining acupuncture and heart failure. Forty-four acute decompensated heart failure patients admitted to the cardiology ward will be randomly assigned into the electroacupuncture treatment group (n = 22) or the sham electroacupuncture control group (n = 22). Participants will receive electroacupuncture treatment for 5 days of their hospital stay. The primary outcome of this study is the difference in total diuretic dose between the two groups during hospitalization. On the day of discharge, follow-up heart rate variability, routine blood tests, cardiac biomarkers, high-sensitivity C-reactive protein (hs-CRP) level, and N-terminal pro b-type natriuretic peptide (NT-pro BNP) level will be assessed. Four weeks after discharge, hs-CRP, NT-pro BNP, heart failure symptoms, quality of life, and a pattern identification questionnaire will be used for follow-up analysis. Six months after discharge, major cardiac adverse events and cardiac function measured by echocardiography will be assessed. Adverse events will be recorded during every visit. The result of this clinical trial will offer evidence of the effectiveness and safety of electroacupuncture for acute decompensated heart failure. Clinical Research Information Service: KCT0002249 .

    To evaluate the effects of discontinuing chronic beta-blocker (BB) treatment on short-term outcome in patients with chronic heart failure (CHF) during acute decompensation. We selected all the patients previously diagnosed with CHF and currently on BB and attended for acute heart failure (AHF) in one of the 35 Spanish emergency departments participating in the EAHFE registry. Patients were classified according to BB maintenance or withdrawal (BBM or BBW, respectively) during the episode. In-hospital mortality was the primary endpoint; and 30-day mortality, 30-day combined endpoint, and prolonged hospitalization were secondary. We used logistic regression for adjustment of results according to the differences between the BBM and BBW groups, and stratified analysis by age, sex, left ventricular ejection fraction, chronic obstructive pulmonary disease, heart rate (HR), and BB type (carvedilol/bisoprolol) was performed. Among 2058 patients receiving chronic BB treatment, 1990 were analyzed: BBM 530 (27 %), BBW 1460 (73 %). Compared to BBM, BBW had a higher in-hospital mortality (5.5 vs 3.0 %; p BBW and in-hospital mortality (OR 1.89; 95 % CI 1.09-3.26) and 30-day mortality (OR 2.01; 95 % CI 1.28-3.15). Stratified analysis indicated no interaction by all the subgroups analyzed, except for HR (p = 0.01 for interaction), which showed a greater negative impact of BBW in patients with HR >80 bpm (OR 2.74; 95 % CI 1.13-6.63). In the absence of clear contraindications, BB treatment should be maintained during AHF episodes in patients already receiving BB at home.

    A considerable proportion of hospitalized patients for acute decompensated heart failure will be readmitted or die in short-term follow-up. In the present study, we aimed to assess the role of admission sodium (Na) and uric acid (UA) levels in the prediction of 30 day post-discharge heart failure readmission or all-cause mortality in advanced heart failure patients admitted with acute decompensation. One hundred and forty consecutive advanced heart failure patients who were admitted for a recent cardiac decompensation were enrolled in this prospective study. Serum Na and UA levels remained statistically unchanged during index admission (P = 0. 54 and 0.19, respectively). Within 30 days post-discharge, composite end point of heart failure rehospitalization or all-cause death occurred in 62 (44.3%) patients (event group). Length of stay was statistically similar between patients in the event and non-event groups (P = 0.38). No correlations were also found between length of stay and left ventricular ejection fraction, serum Na, UA, erythrocyte sedimentation rate (ESR), high-sensitivity C-reactive protein (hs-CRP), creatinine, and N-terminal pro b-type natriuretic peptide (NT-proBNP) levels (all P > 0.05). Lower left ventricular ejection fraction and Na and higher UA on admission were significantly associated with 30 day event both in univariate and multivariate analyses. Given the predictive role of baseline Na and UA for early post-discharge outcome and the absence of significant changes in their levels during initial hospitalization, admission Na and UA can be considered as prognosticators of acute decompensated heart failure, which their prognostic significance cannot be affected by routine acute heart failure therapy.

    There's scarce evidence about cardiovascular events (CV) in patients with hospitalization for acute heart failure (HF) and no indication for immediate device implant. The CARdiac RhYthm monitorING after acute decompensatiON for Heart Failure study was designed to assess the incidence of prespecified clinical and arrhythmic events in this patient population. In this pilot study, 18 patients (12 (67%) male; age 72±10; 16 (89%) NYHA II-III), who were hospitalized for HF with low left ventricular ejection fraction (LVEF) (<40%) and no immediate indication for device implant received an implantable loop recorder (ILR) before hospital discharge. Follow-up visits were scheduled at 3 and 6 months, and at every 6 months until study closure; device data were remotely reviewed monthly. CV mortality, unplanned CV hospitalization, and major arrhythmic events during follow-up were analyzed. During a median follow-up of 593 days, major CV occurred in 13 patients (72%); of those, 7 patients had at least 1 cardiac arrhythmic event, 2 had at least a clinical event (CV hospitalization or CV death), and 4 had both an arrhythmic and a CV event. Six (33%) patients experienced 10 major clinical events, 5 of them (50%) were HF related. During follow-up, 2 (11%) patients died due to a CV cause and 3 (16%) patients received a permanent cardiac device. After an acute HF hospitalization, patients with LVEF<40% and who are not readily eligible for permanent cardiac device implant have a known high incidence of major CV event. In these patients, ILR allows early detection of major cardiac arrhythmias and the ability to react appropriately in a timely manner.

    This study sought to assess the relationship between serum concentrations of the soluble ST2 (sST2) and B-type natriuretic peptide (BNP) and investigate the role of sST2 as a prognosticator in patients hospitalized with acute heart failure (HF) and renal insufficiency. sST2 was measured at admission and discharge in 66 patients hospitalized with acute decompensated HF and renal insufficiency (estimated glomerular filtration rate [eGFR] renal insufficiency (eGFR renal function, even though BNP level was much higher in patients with severe renal insufficiency. During 3 month follow-up, 9 (13.6%) died and 16 (24.2%) were readmitted due to HF aggravation.On multivariate analysis, sST2 at discharge was independently associated with death or HF readmission during 3 months after discharge (hazard ratio, 1.038; 95% confidence interval, 1.011-1.066, P = 0.006). In conclusion, sST2 is not affected by renal function compared with BNP in acute HF patients. The measurement of predischarge sST2 can be helpful in predicting short-term outcomes in acute decompensated HF patients with renal insufficiency.

    Copeptin is a novel biomarker that predicts mortality in lower respiratory tract infections and heart failure (HF), but the diagnostic value of copeptin in acute dyspnea and the prognostic significance of copeptin in acute exacerbation of chronic obstructive pulmonary disease (AECOPD) is not clear. We determined copeptin and NT-proBNP concentrations at hospital admission in 314 patients with acute dyspnea who were categorized by diagnosis. Survival was registered after a median follow-up of 816 days, and the prognostic and diagnostic properties of copeptin and NT-proBNP were analyzed in acute HF (n = 143) and AECOPD (n = 84) separately. The median concentration of copeptin at admission was lower in AECOPD compared to acute HF (8.8 [5.2-19.7] vs. 22.2 [10.2-47.9]) pmol/L, p copeptin (ROC-AUC 0.85 [0.81-0.89] vs. 0.71 [0.66-0.77], p copeptin concentrations predicted mortality in AECOPD (HR per log (ln) unit 1.72 [95% CI 1.21-2.45], p = 0.003) and acute HF (1.61 [1.25-2.09], p copeptin reclassified a significant proportion of patients into a more accurate risk strata in AECOPD (NRI 0.60 [0.19-1.02], p = 0.004) and acute HF (0.39 [0.06-0.71], p = 0.020). Copeptin is a strong prognostic marker in both AECOPD and acute HF, while NT-proBNP concentrations predict mortality only in patients with acute HF. NT-proBNP levels are superior to copeptin levels to diagnose acute HF in patients with acute dyspnea.

    Despite advances in the treatment of heart failure, mortality, the number of readmissions, and their associated health care costs are very high. Heart failure care models inspired by the chronic care model, also known as heart failure programs or heart failure units, have shown clinical benefits in high-risk patients. However, while traditional heart failure units have focused on patients detected in the outpatient phase, the increasing pressure from hospital admissions is shifting the focus of interest toward multidisciplinary programs that concentrate on transitions of care, particularly between the acute phase and the postdischarge phase. These new integrated care models for heart failure revolve around interventions at the time of transitions of care. They are multidisciplinary and patient-centered, designed to ensure continuity of care, and have been demonstrated to reduce potentially avoidable hospital admissions. Key components of these models are early intervention during the inpatient phase, discharge planning, early postdischarge review and structured follow-up, advanced transition planning, and the involvement of physicians and nurses specialized in heart failure. It is hoped that such models will be progressively implemented across the country. Copyright © 2016 Sociedad Española de Cardiología. Published by Elsevier España, S.L.U. All rights reserved.

    Chronic heart failure is a major cause of morbidity and mortality worldwide. Diuretics are regarded as the first-line treatment for patients with congestive heart failure since they provide symptomatic relief. The effects of diuretics on disease progression and survival remain unclear. To assess the harms and benefits of diuretics for chronic heart failure Updated searches were run in the Cochrane Central Register of Controlled Trials in The Cochrane Library (CENTRAL Issue 1 of 4, 2011), MEDLINE (1966 to 22 February 2011), EMBASE (1980 to 2011 Week 07) and HERDIN database (1990 to February 2011). We hand searched pertinent journals and reference lists of papers were inspected. We also contacted manufacturers and researchers in the field. No language restrictions were applied. Double-blinded randomised controlled trials of diuretic therapy comparing one diuretic with placebo, or one diuretic with another active agent (e.g. ACE inhibitors, digoxin) in patients with chronic heart failure. Two authors independently abstracted the data and assessed the eligibility and methodological quality of each trial. Extracted data were analysed by determining the odds ratio for dichotomous data, and difference in means for continuous data, of the treated group compared with controls. The likelihood of heterogeneity of the study population was assessed by the Chi-square test. If there was no evidence of statistical heterogeneity and pooling of results was clinically appropriate, a combined estimate was obtained using the fixed-effects model. This update has not identified any new studies for inclusion. The review includes 14 trials (525 participants), 7 were placebo-controlled, and 7 compared diuretics against other agents such as ACE inhibitors or digoxin. We analysed the data for mortality and for worsening heart failure. Mortality data were available in 3 of the placebo-controlled trials (202 participants). Mortality was lower for participants treated with diuretics than for

    Full Text Available Background: Respiratory failure is of concern in the postoperative period after cardiac surgeries. Invasive ventilation (intermittent positive pressure ventilation [IPPV] carries the risks and complications of intubation and mechanical ventilation (MV. Aims: Noninvasive positive pressure ventilation (NIPPV is an alternative method and as effective as IPPV in treating insufficiency of respiration with less complications and minimal effects on respiratory and hemodynamic parameters next to open-heart surgery. Design: This is a prospective, randomized and controlled study. Materials and Methods: Forty-four patients scheduled for cardiac surgery were divided into two equal groups: Group I (IPPV and Group II (NIPPV. Heart rate (HR, mean arterial pressure (MAP, respiratory rate (RR, oxygen saturation (SpO2, arterial blood gas, weaning time, reintubation, tracheotomy rate, MV time, postoperative hospital stay, and ventilator-associated pneumonia during the period of hospital stay were recorded. Results: There was statistically significant difference in HR between groups with higher in Group I at 30 and 60 min and at 12 and 24 h. According to MAP, it started to increase significantly at hypoxemia, 15 min, 30 min, 4 h, 12 h, and at 24 h which was higher in Group I also. RR, PaO2, and PaCO2showed significant higher in Group II at 15, 30, and 60 min and 4 h. According to pH, there was a significant difference between groups at 15, 30, and 60 min and at 4, 12, and 24 h postoperatively. SpO2showed higher significant values in Group I at 15 and 30 min and at 12 h postoperatively. Duration of postoperative supportive ventilation was higher in Group I than that of Group II with statistically significant difference. Complications were statistically insignificant between Group I and Group II. Conclusion: Our study showed superiority of invasive over noninvasive mode of ventilator support. However, NIPPV (bilevel positive airway pressure was proved to be a safe

    Despite the progress in medical therapy, advanced heart failure (AHF) remains a global epidemic with high morbidity and mortality. Novel cardiac support strategies such as pharmacologic agents, mechanical circulatory support (MCS), and cell- or matrix-based therapies are promising for these patients. The indications, types, and timing of MCS implantation depend to a large extent on the presentation, clinical status of the patient, underlying etiology, and long-term prospects. The presence or absence of end-organ damage has a significant impact on prognosis following MCS initiation. Although many patients with acute AHF may have end-organ damage, their prospect of recovery, once appropriate therapy is instituted, is better than for patients who had AHF for longer periods of time. We consider the multidisciplinary approaches used for the management of AHF and the novel cardiac support strategies (eg, MCS). Appropriate selection of patient, device, time, and end point is essential for better outcomes. © The Author(s) 2014.

    2015-02-01

    Obesity is an important risk factor for the development of heart failure. In normotensive obese patients, a reduced peripheral resistance is typically observed and is accompanied by an increased fluid volume and an increase in cardiac work, resulting in hypertrophy and diastolic heart failure, which can be visualized with echocardiography. However, in the presence of arterial hypertension cardiac geometry is not different to hypertensive heart disease without obesity. Furthermore, the typical changes found with obesity, such as reduced peripheral resistance and increased blood volume, are no longer present. Obstructive sleep apnea (OSA) is very common in obesity and warrants screening but levels of the heart failure marker N-terminal pro-brain natriuretic peptide (NT-ProBNP) might be misleading as the values are lower in obesity than in normal weight controls. Body weight reduction is advisable but difficult to achieve and much more difficult to maintain. Furthermore, diet and exercise has not been proven to enhance life expectancy in obesity. However, with bariatric surgery, long-term weight reduction can be achieved and mortality can be reduced. With effective weight loss and improved clinical outcome after bariatric surgery, treatment of obesity has shifted much more into focus. Regardless of technical challenges in the work-up of obese patients, clinical symptoms suggestive of cardiac disorders warrant prompt investigation with standard techniques following recommendations as established for normal weight patients.

    Renal insufficiency is a well-known predictor of adverse events in patients with acute heart failure syndromes (AHFS). However, it remains unclear whether there are subgroups of AHFS patients in whom renal insufficiency is related to a higher risk of adverse events because of the heterogeneity of this patient population. Therefore, we investigated the relationship between renal insufficiency, clinical features or comorbidities, and the risk of adverse events in patients with AHFS. Of 4842 patients enrolled in the Acute Decompensated Heart Failure Syndromes (ATTEND) registry, 4628 patients (95.6%) were evaluated in the present study in order to assess the relationship of renal insufficiency and clinical features or comorbidities with all-cause mortality after admission. Renal insufficiency was defined as an estimated creatinine clearance of ⩽40 mL/min (calculated by the Cockcroft-Gault formula) at admission. The median follow-up period after admission was 524 (391-789) days. The all-cause mortality rate after admission was significantly higher in patients with renal insufficiency (36.7%) than in patients without renal insufficiency (14.4%). Stratified analysis was performed in order to explore the heterogeneity of the influence of renal insufficiency on all-cause mortality. This analysis revealed that an ischaemic aetiology and a history of diabetes, atrial fibrillation, serum sodium, and anaemia at admission had significant influences on the relationship between renal insufficiency and all-cause mortality. The present study demonstrated that the relationship between renal insufficiency and all-cause mortality of AHFS patients varies markedly with clinical features or comorbidities and the mode of presentation due to the heterogeneity of this patient population.

    Although diuretics are mainly used for the treatment of acute decompensated heart failure (ADHF), inadequate responses and complications have led to the use of extracorporeal ultrafiltration (UF) as an alternative strategy for reducing volume overloads in patients with ADHF. The aim of our study is to perform meta-analysis of the results obtained from studies on extracorporeal venous ultrafiltration and compare them with those of standard diuretic treatment for overload volume reduction in acute decompensated heart failure. MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials databases were systematically searched using a pre‑specified criterion. Pooled estimates of outcomes after 48 h (weight change, serum creatinine level, and all-cause mortality) were computed using random effect models. Pooled weighted mean differences were calculated for weight loss and change in creatinine level, whereas a pooled risk ratio was used for the analysis of binary all-cause mortality outcome. A total of nine studies, involving 613 patients, met the eligibility criteria. The mean weight loss in patients who underwent UF therapy was 1.78 kg [95% Confidence Interval (CI): -2.65 to -0.91 kg; p diuretic therapy. The post-intervention creatinine level, however, was not significantly different (mean change = -0.25 mg/dL; 95% CI: -0.56 to 0.06 mg/dL; p = 0.112). The risk of all-cause mortality persisted in patients treated with UF compared with patients treated with standard diuretics (Pooled RR = 1.00; 95% CI: 0.64-1.56; p = 0.993). Compared with standard diuretic therapy, UF treatment for overload volume reduction in individuals suffering from ADHF, resulted in significant reduction of body weight within 48 h. However, no significant decrease of serum creatinine level or reduction of all-cause mortality was observed.

    Full Text Available Na+ can be stored in muscle and skin without commensurate water accumulation. The aim of this study was to assess Na+ and H2O in muscle and skin with MRI in acute heart failure patients before and after diuretic treatment and in a healthy cohort.Nine patients (mean age 78 years; range 58-87 and nine age and gender-matched controls were studied. They underwent 23Na/1H-MRI at the calf with a custom-made knee coil. Patients were studied before and after diuretic therapy. 23Na-MRI gray-scale measurements of Na+-phantoms served to quantify Na+-concentrations. A fat-suppressed inversion recovery sequence was used to quantify H2O content.Plasma Na+-levels did not change during therapy. Mean Na+-concentrations in muscle and skin decreased after furosemide therapy (before therapy: 30.7±6.4 and 43.5±14.5 mmol/L; after therapy: 24.2±6.1 and 32.2±12.0 mmol/L; p˂0.05 and p˂0.01. Water content measurements did not differ significantly before and after furosemide therapy in muscle (p = 0.17 and only tended to be reduced in skin (p = 0.06. Na+-concentrations in calf muscle and skin of patients before and after diuretic therapy were significantly higher than in healthy subjects (18.3±2.5 and 21.1±2.3 mmol/L.23Na-MRI shows accumulation of Na+ in muscle and skin in patients with acute heart failure. Diuretic treatment can mobilize this Na+-deposition; however, contrary to expectations, water and Na+-mobilization are poorly correlated.

    We aimed to characterize abnormal liver function tests in patients with heart failure (HF), as they are commonly encountered yet poorly defined. We used data from ASCEND-HF (Acute Study of Clinical Effectiveness of Nesiritide in Decompensated Heart Failure) to characterize associations with baseline liver function tests (LFTs). Each LFT was analysed as both a continuous and dichotomous variable [normal vs. abnormal; bilirubin >1.0 mg/dL; aspartate aminotransferase (AST) and alanine aminotransferase (ALT) >35 mmol/L]. Logistic regression assessed the association of LFTs and 30-day all-cause mortality and HF rehospitalization, and Cox proportional hazards assessed the association with 180-day all-cause mortality among patients alive at a 30-day landmark. In ASCEND-HF, 4228 (59%) had complete admission LFT data. Of these, 42% had abnormal bilirubin, 22% had abnormal ALT, and 30% had abnormal AST. Patients with abnormal LFTs were younger, had lower body mass index, and lower left ventricular ejection fraction. In multivariable models, increased total bilirubin was associated with increased 30-day mortality or HF rehospitalization [hazard ratio (HR) 1.17 per 1 mg/dL increase, 95% confidence interval (CI) 1.04, 1.32; P = 0.012], but not with an increase in 180-day mortality (HR 1.10, 95% CI 0.97, 1.25; P = 0.13) per 1 mg/dl increase. Compared with normal bilirubin levels, abnormal bilirubin was associated with increased 30-day mortality or HF rehospitalization (HR 1.24, 95% CI 1.00, 1.54; P = 0.048) and 180-day mortality (HR 1.32, 95% CI 1.08, 1.62; P = 0.007). We found no association with AST or ALT and outcomes. Greater than 40% of patients hospitalized with acute HF had abnormal LFTs. After multivariable adjustment, only elevated bilirubin was independently associated with worse clinical outcomes and may represent an important prognostic variable. © 2015 The Authors European Journal of Heart Failure © 2015 European Society of Cardiology.

    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 are scant. Eccentric (ECC) cycling is a novel exercise modality that may be particularly suited to patients with CHF, but the acute impacts of ECC cycling 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. Eleven patients with heart failure with reduced ejection fraction (HFrEF) took part in discrete bouts of ECC and CON cycling. Before and immediately after exercise, vascular function was assessed by measuring diameter and flow-mediated dilation (FMD) of the brachial artery. Platelet function was measured by the flow cytometric determination of glycoprotein IIb/IIIa activation and granule exocytosis in the presence and absence of platelet agonists. ECC cycling increased baseline artery diameter (pre: 4.0 ± 0.8 mm vs. post: 4.2 ± 0.7 mm; P = 0.04) and decreased FMD%. When changes in baseline artery diameter were accounted for, the decrease in FMD post-ECC cycling was no longer significant. No changes were apparent after CON. Neither ECC nor CON cycling resulted in changes to any platelet-function measures (all P > 0.05). These results suggest that both ECC and CON cycling, at a moderate intensity and short duration, can be performed by patients with HFrEF without detrimental impacts on vascular or platelet function. NEW & NOTEWORTHY This is the first evidence to indicate that eccentric (ECC) cycling can be performed relatively safely by patients with chronic heart failure (CHF), as it did not result in impaired vascular or platelet function compared with conventional cycling

    Chronic heart failure (CHF) is associated with an increased risk of thrombosis and thromboembolic events, including stroke and venous thromboembolism. which may be related to a prothrombotic or hypercoagulable state. Acute vigorous exercise has been associated with activation of hemostasis, and this risk may well be particularly increased in patients with CHF. The study was undertaken to determine whether acute exercise would adversely affect abnormalities of hemorheological (fibrinogen, plasma viscosity, hematocrit), endothelial (von Willebrand factor), and platelet markers (soluble P selectin) in patients with CHF. We studied 22 ambulant outpatients (17 men; mean age 65+/-9 years) with stable CHF (New York Heart Association class II-III and a left ventricular ejection fraction of exercised to exhaustion on a treadmill. Results were compared with 20 hospital controls (patients with vascular disease, but free of CHF) and 20 healthy controls. Baseline von Willebrand factor (p = 0.01) and soluble P-selectin (p = 0.006) levels were significantly elevated in patients with CHF when compared with controls. In the patients with CHF who were exercised, plasma viscosity, fibrinogen, and hematocrit levels increased significantly, both immediately post exercise and at 20 min into the recovery period (repeated measures analysis of variance, all pexercise workload and the maximal changes in plasma viscosity in the patients with CHF (Spearman r = 0.5, p = 0.02). Plasma viscosity levels increased with exercise in the hospital control group, although no other exercise-induced changes were noted in this group. The present study indicates that the hemorheological indices. fibrinogen, and hematocrit specifically increase during acute exercise in patients with CHF. Although moderate exercise should be encouraged in patients with CHF, vigorous exercise should probably be avoided in view of its potential prothrombotic effects in this high-risk group of patients.

    Pulmonary thromboembolism (PTE) is a very common condition with high mortality. Although some scales include heart failure (HF) as a risk factor of PTE, none of them have assessed the contribution of the different kinds of HF, i. e. with reduced or preserved left ventricular ejection fraction (LVEF) to the in-hospital outcome of patients admitted with PTE. A retrospective study assessing a cohort of patients consecutively admitted to hospital with a PTE from 2012-2014. Baseline epidemiological characteristics, treatment during admission and prognostic variables during hospitalization were analyzed. Primary endpoint was defined as hospital mortality for any cause. A total of 442 patients with PTE were included (88 with prior HF). Patients with a history of HF were older, more frequently had hypertension, diabetes mellitus, chronic kidney or pulmonary disease, cancer, and coronary artery disease, and showed less LVEF (P<.001). Hospital mortality was significantly higher in patients with prior HF (21.6 vs. 6.8%, P<.001). Multivariate analysis found that HF with reduced LVEF but not HF with preserved LVEF resulted as an independent risk factor (respectively OR 5.54; 95% CI 2.12-14.51 and OR 129; 95% CI 0.72-4.44). Patients with prior HF admitted to hospital with PTE should be considered a high-risk population, since they present high in-hospital mortality. In our cohort, patients with prior HF and reduced LVEF presented a poorer prognosis than those with preserved LVEF. Copyright © 2016 Elsevier España, S.L.U. All rights reserved.

    The outcome of patients with chronic heart failure (CHF) following an ischaemic event is poorly understood. We evaluated the management and outcomes of CHF patients presenting with an acute coronary syndrome (ACS) and explored changes in outcomes over time. A total of 5556 patients enrolled in the Australia-New Zealand population of the Global Registry of Acute Coronary Events (GRACE) between 1999 and 2007 were included. Patients with CHF (n = 609) were compared with those without CHF (n = 4947). Patients with CHF were on average 10 years older, were more likely to be female, had more co-morbidities and cardiac risk factors, and were more likely to have a prior history of angina, myocardial infarction, and revascularization by coronary artery bypass graft (CABG) when compared with those without CHF. CHF was associated with a substantial increase in in-hospital renal failure [odds ratio (OR) 1.76, 95% confidence interval (CI) 1.15-2.71], readmission post-discharge (OR 1.47, 95% CI 1.17-1.90), and 6-month mortality (OR 2.25, 95% CI 1.55-3.27). Over the 9 year study period, in-hospital and 6 month mortality in those with CHF declined by absolute rates of 7.5% and 14%, respectively. This was temporally associated with an increase in prescription of thienopyridines, beta-blockers, statins, and angiotensin II receptor blockers, increased rates of coronary angiography, and 31.8% absolute increase in referral rates for cardiac rehabilitation. Acute coronary syndrome patients with pre-existing CHF are a very high risk group and carry a disproportionate mortality burden. Encouragingly, there was a marked temporal improvement in outcomes over a 9 year period with an increase in evidence-based treatments and secondary preventative measures.

    Increased aortic stiffness may be an important cause of acute heart failure (AHF). Clinical scenario (CS), which classifies the pathophysiology of AHF based on the initial systolic blood pressure (sBP), was proposed to provide the most appropriate therapy for AHF patients. In CS, elevated aortic stiffness, vascular failure, has been considered as a feature of patients categorized as CS1 (sBP > 140 mmHg at initial presentation). However, whether elevated aortic stiffness, vascular failure, is present in such patients has not been fully elucidated. Therefore, we assessed aortic stiffness in AHF patients using the cardio-ankle vascular index (CAVI), which is considered to be independent of instantaneous blood pressure. Sixty-four consecutive AHF patients (mean age, 70.6 ± 12.8 years; 39 men) were classified with CS, based on their initial sBP: CS1: sBP > 140 mmHg (n = 29); CS2: sBP 100-140 mmHg (n = 22); and CS3: sBP < 100 mmHg (n = 13). There were significant group differences in CAVI (CS1 vs. CS2 vs. CS3: 9.7 ± 1.4 vs. 8.4 ± 1.7 vs. 8.3 ± 1.7, p = 0.006, analysis of variance). CAVI was significantly higher in CS1 than in CS2 (p = 0.02) and CS3 (p = 0.04). CAVI did not significantly correlate with sBP at the time of measurement of CAVI (r = 0.24 and p = 0.06). Aortic stiffness assessed using blood pressure-independent methodology apparently increased in CS1 AHF patients. We conclude that vascular failure is a feature of CS1 AHF initiation.

    Hypoalbuminemia is common in acute heart failure (HF) patients and has been associated with increased hospital mortality and long-term mortality. Undernutrition is a factor causing hypoalbuminemia. The PICNIC study results show that a nutritional intervention in undernourished acute HF patients reduces the risks of all-cause death and of readmission for HF. We aimed to investigate whether the efficacy of a nutritional intervention is consistent among the subgroups of patients with and without hypoalbuminemia. In PICNIC study, a total of 120 malnourished hospitalized patients due to acute HF were randomized to conventional HF treatment or conventional HF treatment combined with an individualized nutritional intervention. The primary endpoint was a composite of all-cause death or readmission for worsening of HF, with a maximum follow-up of 12 months. In this post-hoc sub-analysis we assessed the interaction of the effects of a nutritional intervention among patients with and without hypoalbuminemia. Analysis was by intention to treat. 59 (49,2%) patients demonstrated hypoalbuminemia and 61 (50,8%) had normalbuminemia. At 12 months, the number of events for the primary endpoint in the intervention group compared with the control group was consistent among patients with hypoalbuminemia (28.6% intervention vs 61.3% control, HR 0,35, 95% CI 0,15-0,81) and those without (25.8% intervention vs 60% control, HR 0,35, 95% CI 0,15-0,79; interaction p = 0,86). There was no evidence that the relative efficacy of a nutritional intervention in undernourished acute HF patients was different between patients with normalbuminemia and those with hypoalbuminemia.

    Advances in heart failure (HF) treatments have prolonged survival, but more patients die of HF than of any type of cancer. Little is known about the current practice in end-of-life (EOL) care in HF. Two EOL cohorts (HF and cancer) were identified using Medicare data linked with pharmacy and cancer registry data. We assessed use of hospice, opiates, and acute care services (hospitalizations, emergency department [ED] visits, intensive care unit [ICU] admissions, and death in acute care). Time trends and predictors of use were assessed using multivariate regression including demographics and cardiovascular and noncardiovasuclar comorbidities. Among 5,836 HF patients with median age of 85, 77% female and 4% black, 20% were referred to hospice compared to 51% of 7,565 cancer patients. A modest rise in hospice use over time was parallel in the 2 groups. Twenty-two percent of HF patients filled opiate prescriptions during 60 days before death compared to 46% of cancer patients. Use of acute care services in the 30 days before death was higher for HF (64% vs 39% for ED visits, 60% vs 45% for hospitalizations, and 19% vs 7% for ICU admission). More HF patients died during acute hospitalizations than cancer patients (39% vs 21%). Patients dying of HF were less likely to be supported by hospice and opiates but more likely to die in hospitals than patients with cancer. Our study suggests that opportunities may exist to improve hospice and opiate use in HF patients. Copyright (c) 2010 Mosby, Inc. All rights reserved.

    To identify baseline predictors of worsening renal function (WRF) in an acute decompensated heart failure (ADHF) patient population receiving continuous infusion loop diuretics. Retrospective observational analysis. Academic tertiary medical center. A total of 177 patients with ADHF receiving continuous infusion loop diuretics from January 2006 through June 2009. The mean patient age was 61 years, 63% were male, ~45% were classified as New York Heart Association functional class III, and the median length of loop diuretic infusion was 4 days. Forty-eight patients (27%) developed WRF, and 34 patients (19%) died during hospitalization. Cox regression time-to-event analysis was used to determine the time to WRF based on different demographic and clinical variables. Baseline serum albumin 3 g/dl or less was the only significant predictor of WRF (hazard ratio [HR] 2.87, 95% confidence interval [CI] 1.60-5.16, p=0.0004), which remained significant despite adjustments for other covariates. Serum albumin 3 g/dl or less is a practical baseline characteristic associated with the development of WRF in patients with ADHF receiving continuous infusion loop diuretics. © 2013 Pharmacotherapy Publications, Inc.

    β-Blockers (BBs) are an essential class of cardiovascular medications for reducing morbidity and mortality in patients with heart failure (HF). However, a large body of data indicates that BBs should not be used as first-line therapy for hypertension (HTN). Additionally, new data have questioned the role of BBs in the treatment of stable coronary heart disease (CHD). However, these trials mainly tested the non-vasodilating β1 selective BBs (atenolol and metoprolol) which are still the most commonly prescribed BBs in the USA. Newer generation BBs, such as the vasodilating BBs carvedilol and nebivolol, have been shown not only to be better tolerated than non-vasodilating BBs, but also these agents do not increase the risk of diabetes mellitus (DM), atherogenic dyslipidaemia or weight gain. Moreover, carvedilol has the most evidence for reducing morbidity and mortality in patients with HF and those who have experienced an acute myocardial infarction (AMI). This review discusses the cornerstone clinical trials that have tested BBs in the settings of HTN, HF and AMI. Large randomised trials in the settings of HTN, DM and stable CHD are still needed to establish the role of BBs in these diseases, as well as to determine whether vasodilating BBs are exempt from the disadvantages of non-vasodilating BBs.

    To investigate the effect of recombinant human brain natriuretic peptide (rhBNP) on renal function in patients with acute heart failure (AHF) following acute myocardial infarction (AMI). Consecutive patients with AHF following AMI were enrolled in this clinical trial. Eligible patients were randomly assigned to receive rhBNP (rhBNP group) or nitroglycerin (NIT group). Patients in the rhBNP group received rhBNP 0.15 μg /kg bolus injection after randomization followed by an adjusted-dose (0.0075-0.020 μg/kg/min) for 72 hours, while patients in NIT received infusion of nitroglycerin with an adjusted-dose (10-100 μg/kg/min) for 72 hours in NIT group. Standard clinical and laboratory data were collected. The levels of serum creatinine (SCr), urea, β-2 microglobulin and cystatin C were measured at baseline and repeated at the end of the 24, 48 and 72 hours after infusion. The primary end point was the incidence of acute renal dysfunction, which was defined as an increase in SCr > 0.5 mg/dl (> 44.2 μmol/L) or 25% above baseline SCr value. The occurrence of major adverse cardiac event (MACE) was followed up for 1 month. Of the 50 patients enrolled, 26 were randomly assigned to rhBNP and 24 to nitroglycerin (NIT). There were no significant differences in baseline characteristics between the two groups (all P > 0.05). The baseline concentrations of SCr, urea, β-2 microglobulin and cystatin C at admission were similar in the two groups. However, the concentrations of SCr and urea were significantly higher in rhBNP group than those in NIT group at hour 24 and 48 after treatments (all P acute renal dysfuntion in rhBNP group was higher (9/26 vs. 2/24, P = 0.040). The results of multiple logistic regression found that the use of rhBNP was an independent predictor of acute renal dysfunction in patients with AHF following AMI (OR, 0.162; 95% CI, 0.029 to 0.909; P = 0.039). the incidence of acute renal dysfuntion in rhBNP group was higher, and the use of rhBNP was an

    To address the mechanisms responsible for the increase in LV filling pressures induced by acute hypertension transients in patients with heart failure with preserved ejection fraction (HFpEF). Multiple-beat pressure-volume loops were recorded during inferior vena cava occlusion in 39 HFpEF patients and 20 controls during handgrip and atrial pacing. We measured the contribution of relaxation, elastic recoil, and stiffness to instantaneous diastolic pressure using a novel processing method. Fibrosis was quantified from endomyocardial biopsies. HFpEF patients showed higher diastolic pressures and stiffness constant than controls (P degree of pressure-sensitivity of stiffness correlated with myocardial collagen volume and crosslinking (R = 0.40 to 0.82 for all). Acute chamber stiffening is the main mechanism responsible for rising late-diastolic pressures when HFpEF patients undergo hypertension transients. This stiffening behaviour is related to impaired dynamic systolic-diastolic interactions and correlates with matrix remodelling. Ventricular-vascular relationships are a promising target in HFpEF and should be taken into account when assessing diastolic function.

    Intravenous loop diuretics are still the cornerstone of therapy in acute decompensated heart failure, however, the optimal dosage and administration strategies remain poorly defined particularly in patients with an associated renal dysfunction. This is a single-center, pilot, randomized trial involving patients with acute HF and renal dysfunction. Patients were assigned to receive continuous furosemide infusion (cIV) or bolus injections of furosemide (iIV). Primary end points were the evaluation of urine output volumes, renal function, and b-type natriuretic peptide (BNP) levels during treatment time. Secondary end point included: weight loss, length of hospitalization, differences in plasma electrolytes, need for additional treatment, and evaluation of cardiac events during follow-up period. 57 patients were included in the study. The cIV group showed an increase in urine output (2,505 ± 796 vs 2140 ± 468 ml/day, p diuretics are responsible for worsening renal function and to define the best modality of administration.

    Heart failure (HF) is an increasingly prevalent long-term condition that affects around 900,000 people in the United Kingdom (National Institute for Health and Clinical Excellence). The study examined how HF services in the English National Health Service (NHS) were changing, focusing particularly on the primary/secondary care interface. The maintenance of continuity in care in the face of increasing demand and financial pressures on health and social care was a key concern. Semi-structured interviews were conducted with 22 members of staff working in HF services in three NHS acute Trusts in the West Midlands of England. Interviews were conducted between April and December 2011 with purposively selected participants and data were analysed using the Framework Method. Four main themes emerged from the analysis: service context, capacity, the primary/secondary interface and communication across boundaries. Barriers to, and facilitators of, continuity of care for patients with HF were identified within these themes. The findings provide insights into the structure, management and work of HF services in the acute and community settings. They highlight how local systems for the management of HF patients are developing in ways which are not necessarily consistent with national policy. © 2014 John Wiley & Sons Ltd.

    Elevated levels of circulating pro-inflammatory biomarkers in patients with both ischaemic and non-ischaemic heart failure (HF) correlate with disease severity and prognosis. Experimental studies have shown activation of immune response mechanisms in the heart to provoke cardiac adverse remodelling and cause left ventricular dysfunction. Consequently, most of the clinical trials targeting elements of the immune response in HF attempted to modulate the inflammatory response. Surprisingly, clinical studies targeting immune effectors were either neutral or even increased pre-specified clinical endpoints, and some studies resulted in worsening of HF. This review discusses immune mediators involved in the pathogenesis and progression of HF and potential therapeutic applications targeting inflammation in HF. Besides more obvious settings featuring immune activation such as inflammatory or ischaemic cardiomyopathy, the relevance of immune activation in acute or chronic HF of other origins, including volume overload or valvular heart disease, is highlighted. Understanding how cell-specific and molecular mechanisms of the immune response interfere with cardiac remodelling in HF may open new avenues to design biomarkers or druggable targets. © 2017 The Authors.

    Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equations estimate glomerular filtration rate (eGFR) more accurately than the Modification of Diet in Renal Disease (MDRD) equation. The aim of this study was to evaluate whether CKD-EPI equations based on serum creatinine and/or cystatin C (CysC) predict risk for adverse outcomes more accurately than the MDRD equation in a hospitalized cohort of patients with acute decompensated heart failure (ADHF). A total of 526 subjects with ADHF were studied. Blood was collected within 48 hours from admission. eGFR was calculated with the use of MDRD and CKD-EPI equations. The occurrences of mortality and heart failure (HF) hospitalization were recorded. Over the study period (median 365 days [interquartile range 238-370]), 305 patients (58%) died or were rehospitalized for HF. Areas under the receiver operator characteristic curves for CKD-EPI CysC and CKD-EPI creatinine-CysC equations were significantly higher than that for the MDRD equation, especially in patients with >60 mL min(-1) 1.73 m(-2). After multivariate adjustment, all eGFR equations were independent predictors of adverse outcomes (P EPI CysC and CKD-EPI creatinine-CysC equations were associated with significant improvement in reclassification analyses (net reclassification improvements 10.8% and 12.5%, respectively). In patients with ADHF, CysC-based CKD-EPI equations were superior to the MDRD equation for predicting mortality and/or HF hospitalization especially in patients with >60 mL min(-1) 1.73 m(-2), and both CKD-EPI equations improved clinical risk stratification.

    The aim of this study was to assess the prevalence, clinical features, and in-hospital outcomes of heart failure in patients with acute coronary syndrome (ACS). The Saudi Project for Assessment of Coronary Events recruited patients admitted with ACS from 17 hospitals in Saudi Arabia from 2005 to 2007. The outcomes of ACS patients with congestive heart failure (CHF) compared with those without CHF were analyzed. A total of 4523 patients with ACS were identified, of whom 905 (20%) had CHF. Compared with no CHF, patients with CHF were older (62±13.1 vs. 57±12.9 years; P=0.001), less likely to be men (70 vs. 79%; P=0.001), likely to present with non-ST-segment elevation myocardial infarction (48 vs. 36%; P=0.001), likely to have diabetes (71 vs. 54%; P=0.001), hypertension (64 vs. 54%; P=0.001) and previous history of coronary artery disease (53 vs. 43%; P=0.001), and likely to have significant left ventricular systolic dysfunction (left ventricular ejection fraction coronary intervention (19 vs. 50%; P=0.001). Adjusted in-hospital mortality and cardiogenic shock were higher in the CHF group (odds ratio 4.43, 95% confidence interval 2.52-7.78; and odds ratio 3.51, 95% confidence interval 2.23-5.52), respectively. ACS patients with CHF in the Saudi Project for Assessment of Coronary Events were older, more likely to have more cardiac risk factors, and less likely to be treated with optimum medical treatment on admission. These findings were associated with higher incidence of their in-hospital adverse outcomes. More aggressive treatment is warranted to improve prognosis.

    In patients with acute heart failure (AHF), dyspnea relief is the most immediate goal. Renal dysfunction, diuretic resistance, and hyponatremia represent treatment impediments. It was hypothesized that the addition of tolvaptan to a background diuretic improved dyspnea early in patients selected for an enhanced vasopressin antagonism response. In a double-blind trial, patients were randomized to tolvaptan 30 mg/day or placebo. Study entry required hospitalization within the previous 36 h, active dyspnea, and any of the following: 1) estimated glomerular filtration rate tolvaptan (-2.4 ± 2.1 kg vs. -0.9 ± 1.8 kg; p tolvaptan (p = 0.01). There were 2 significant treatment-by-subgroup interactions: patients without elevated jugular venous pressure and those without ascites showed directional favorability of tolvaptan over placebo for the primary endpoint compared with patients with these findings. Despite rapid and persistent weight loss with tolvaptan compared with placebo, in patients with AHF who were selected for greater potential benefit from vasopressin receptor inhibition, tolvaptan was not associated with greater early improvement in dyspnea. Apparent subsequent differences in dyspnea warrant further exploration of the temporal relationship between diuresis and dyspnea relief and a possible clinical role for tolvaptan.

    Because hepatic dysfunction is common in patients with heart failure (HF), the Model for End-Stage Liver Disease (MELD) may be attractive for risk stratification. Although alternative scores such as the MELD-XI or MELD-Na may be more appropriate in HF populations, the short-term clinical implications of these in patients with acute heart failure (AHF) are unknown. The MELD-XI and MELD-Na were calculated at baseline in 453 patients with AHF in the DOSE-AHF and ROSE-AHF trials. The correlations and associations for each score with cardiorenal biomarkers, short-term end points at 72 hours including worsening renal function and clinical events to 60 days were determined. The median MELD-XI and MELD-Na was 16 and 17, respectively. Both were correlated with baseline cystatin C, amino terminus pro-B-type natriuretic peptide, and plasma renin activity (p 0.05 for both) at 72 hours. Neither score was associated with worsening renal function or worsening HF (p >0.05 for all). Similarly, both the MELD-XI and MELD-Na were not associated with 60-day death/any rehospitalization and 60-day death/HF rehospitalization in adjusted analyses when analyzes as a dichotomous or continuous variable (p >0.05 for all). In conclusion, the alternative MELD scores correlated with baseline cardiorenal biomarkers, and lower baseline MELD scoring was associated with higher diuretic efficiency and a slight increase in cystatin C through 72 hours. However, MELD-Na and MELD-XI were not predictive of 60-day clinical events. Copyright © 2017 Elsevier Inc. All rights reserved.

  3. Obesity and heart failure.

    Epidemiological studies have recently shown that obesity, and abdominal obesity in particular, is an independent risk factor for the development of heart failure (HF). Higher cardiac oxidative stress is the early stage of heart dysfunction due to obesity, and it is the result of insulin resistance, altered fatty acid and glucose metabolism, and impaired mitochondrial biogenesis. Extense myocyte hypertrophy and myocardial fibrosis are early microscopic changes in patients with HF, whereas circumferential strain during the left ventricular (LV) systole, LV increase in both chamber size and wall thickness (LV hypertrophy), and LV dilatation are the early macroscopic and functional alterations in obese developing heart failure. LV hypertrophy leads to diastolic dysfunction and subendocardial ischemia in obesity, and pericardial fat has been shown to be significantly associated with LV diastolic dysfunction. Evolving abnormalities of diastolic dysfunction may include progressive hypertrophy and systolic dysfunction, and various degrees of eccentric and/or concentric LV hypertrophy may be present with time. Once HF is established, overweight and obese have a better prognosis than do their lean counterparts with the same level of cardiovascular disease, and this phenomenon is called "obesity paradox". It is mainly due to lower muscle protein degradation, brain natriuretic peptide circulating levels and cardio-respiratory fitness than normal weight patients with HF.

    More than 25% of Medicare patients hospitalized for heart failure are readmitted within 30 days. The contributions of numeracy and health literacy to recidivism for patients with acute heart failure (AHF) are not known. A cohort of patients with acute heart failure who presented to 4 emergency departments between January 2008 and September 2011. Research assistants administered subjective measures of numeracy and health literacy; 30-day follow-up was performed by phone interview. Recidivism was defined as any unplanned return to the emergency department or hospital within 30 days of the index emergency department visit for AHF. Multivariable logistic regression adjusting for patient age, sex, race, insurance status, hospital site, days eligible for recidivism, chronic kidney disease, abnormal hemoglobin, and low ejection fraction evaluated the relation between numeracy and health literacy with 30-day recidivism. Of the 709 patients included in the analysis, 390 (55%) had low numeracy skills and 258 (37%) had low literacy skills. Low numeracy was associated with increased odds of recidivism within 30 days (adjusted odds ratio, 1.41; 95% confidence interval, 1.00-1.98; P=0.048). For low health literacy, adjusted odds ratio of recidivism was 1.17 (95% confidence interval, 0.83-1.65; P=0.37). Low numeracy was associated with greater odds of 30-day recidivism. Further investigation is warranted to determine whether addressing numeracy and health literacy may reduce 30-day recidivism for patients with acute heart failure.

    The significance of worsening renal function (WRF) in patients admitted for acute decompensated heart failure (ADHF) is still controversial. We hypothesised that changes in brain natriuretic peptide (BNP) might identify patients with optimal diuretic responsiveness resulting in transient WRF, not negatively affecting the prognosis. Our aim was to verify if in-hospital trends of BNP might be helpful in the stratification of patients with WRF after treatment for ADHF. 122 consecutive patients admitted for ADHF were enrolled. Brain natriuretic peptide and eGFR were evaluated at admission and discharge. A 20% relative decrease in eGFR defined WRF, whereas a BNP reduction ≥40% was considered significant. The primary combined endpoint was death/urgent heart transplantation and re-hospitalisation for ADHF. Worsening renal function occurred in 23% of patients without differences in outcome between patients with and without WRF (43% vs. 45%, p=0.597). A significant reduction in BNP levels over the hospitalisation occurred in 59% of the overall population and in 71% of patients with WRF. At a median follow-up of 13.0 (IQR 6-36) months, WRF patients with ≥40% BNP reduction had a lower rate of death/urgent heart transplantation/re-hospitalisation compared to WRF patients without BNP reduction (30% and 75%, respectively; p=0.007). Favourable BNP trend was the strongest variable in predicting the outcome in WRF patients (HR 0.222, 95% CI 0.066-0.753, p=0.016). Worsening renal function does not affect the prognosis of ADHF and, when associated with a significant BNP reduction, identifies patients with adequate decongestion at discharge and favourable outcome.

    Full Text Available Defibrillation threshold (DFT testing is usually recommended after device implantation to confirm appropriate implantable cardioverter defibrillator (ICD/cardiac resynchronization therapy defibrillator (CRT-D function [1,2]. However, induction of ventricular fibrillation may result in hemodynamic compromise, and cardioversion itself may cause myocardial injury [3,4]. We report on a CRT-D patient with acute myocardial infarction who died due to multiple organ failure 1 day after DFT testing. Our case emphasizes the importance of deciding whether DFT testing should be performed for patients with very severe heart failure in the acute stage of myocardial infarction.

    Heart failure (HF) can be associated with a higher resting heart rate (HR), and an elevated HR is associated with adverse long-term events. However, the mechanistic and causal role of HR in HF is unclear. This study aimed to investigate changes in HR during hospitalization, and the association between discharge HR and clinical outcomes as well as an interaction with beta-blocker therapy in patients with acute decompensated HF (ADHF). We studied 2906 patients with an LVEF ≤35%, without AF, who were enrolled in the ASCEND-HF trial. A total of 2492 (85.8%) patients had a HR ≥70 b.p.m. at baseline and 1580 (54.4%) patients were on beta-blocker treatment. Although HR was gradually reduced from baseline to discharge (85.5 ± 15.9 b.p.m. at baseline, 81.7 ± 14.1 b.p.m. at 24 h from treatment initiation, and 79.1 ± 12.2 b.p.m. at discharge), 80.2% of the patients still had a HR ≥70 b.p.m. at discharge. Patients with a HR ≥70 b.p.m. at discharge had significantly lower survival rates than those with a HR beta-blocker therapy at discharge (P = 0.82). Despite current beta-blocker therapy, many patients with hospitalized ADHF with reduced LVEF have relatively high discharge HR, and discharge HR is associated with higher mortality. Further studies are warranted to determine the optimal strategy for HR control to improve outcomes. © 2016 The Authors. European Journal of Heart Failure © 2016 European Society of Cardiology.

    Morbidity and mortality after admission for acute heart failure remain prohibitively high. In that setting, plasma levels of antigen carbohydrate 125 have shown to correlate with the severity of fluid overload and the risk of mortality and readmission. Preliminary data suggests a potential role of antigen carbohydrate 125 to guide therapy. The objective of this study is to evaluate the prognostic effect of an antigen carbohydrate 125-guided management strategy vs standard therapy in patients recently discharged for acute heart failure. This is a multicenter, randomized, single-blind, efficacy trial study of patients recently discharged from acute heart failure ( 35 U/ml. A randomization scheme was used to allocate participants (in a 1:1 ratio) to receive therapy guided by antigen carbohydrate 125 (aiming to keep normal values) or standard treatment. Mainly, antigen carbohydrate 125-guided therapy is focused on the frequency of monitoring and titration of decongestive therapies and statins. As of December 10, 2013, there were 383 patients enrolled. The primary outcome was the composite of 1-year all-cause mortality or rehospitalization for acute heart failure. Analysis was planned to be intention-to-treat. Discovering novel therapeutic strategies or finding better ways of optimizing established treatments have become a health care priority in heart failure. This study will add important knowledge about the potential of antigen carbohydrate 125 as a management tool for monitoring and titration of therapies where optimal utilization has not been well defined, such as diuretics and statins.

    2012-11-01

    Full Text Available Abstract Background Optimal management of acute right heart failure following the implantation of a left ventricular assist device requires a reliable estimation of left ventricular preload and contractility. This is possible by real-time pump blood flow measurements. Clinical case We performed implantation of a continuous flow left ventricular assist device in a 66 years old female patient with an end-stage heart failure on the grounds of a dilated cardiomyopathy. Real-time pump blood flow was directly measured by an ultrasonic flow probe placed around the outflow graft. Diagnosis The progressive decline of real time flow and the loss of pulsatility were associated with an increase of central venous pressure, inotropic therapy and progressive renal failure suggesting the presence of an acute right heart failure. Diagnosis was validated by echocardiography and thermodilution measurements. Treatment Temporary mechanical circulatory support of the right ventricle was successfully performed. Real time flow measurement proved to be a useful tool for the diagnosis and ultimately for the management of right heart failure including the weaning from extracorporeal membrane oxygenation.

    The ShockOmics study (ClinicalTrials.gov identifier NCT02141607) is a multicenter prospective observational trial aimed at identifying new biomarkers of acute heart failure in circulatory shock, by means of a multiscale analysis of blood samples and hemodynamic data from subjects with circulatory shock. Ninety septic shock and cardiogenic shock patients will be recruited in three intensive care units (ICU) (Hôpital Erasme, Université Libre de Bruxelles, Belgium; Hospital Universitari Mutua Terrassa, Spain; Hôpitaux Universitaires de Genève, Switzerland). Hemodynamic signals will be recorded every day for up to seven days from shock diagnosis (time T0). Clinical data and blood samples will be collected for analysis at: i) T1  5 and lactate levels ≥ 2 mmol/L. The exclusion criteria are: expected death within 24 h since ICU admission; > 4 units of red blood cells or >1 fresh frozen plasma transfused; active hematological malignancy; metastatic cancer; chronic immunodepression; pre-existing end stage renal disease requiring renal replacement therapy; recent cardiac surgery; Child-Pugh C cirrhosis; terminal illness. Enrollment will be preceded by the signature of the Informed Consent by the patient or his/her relatives and by the physician in charge. Three non-shock control groups will be included in the study: a) healthy blood donors (n = 5); b) septic patients (n = 10); c) acute myocardial infarction or patients with prolonged acute arrhythmia (n = 10). The hemodynamic data will be downloaded from the ICU monitors by means of dedicated software. The blood samples will be utilized for transcriptomics, proteomics and metabolomics ("-omics") analyses. ShockOmics will provide new insights into the pathophysiological mechanisms underlying shock as well as new biomarkers for the timely diagnosis of cardiac dysfunction in shock and quantitative indices for assisting the therapeutic management of shock patients.

    Transcatheter aortic valve implantation (TAVI) is recommended for patients with severe symptomatic aortic stenosis (AS) who are at prohibitive/high risk for surgical aortic valve replacement (SAVR). Patients with severe AS may experience acute decompensated heart failure (HF) that is resistant to medical therapy. We report our TAVI experience in treating patients with unstable AS who require urgent intervention for their aortic valve disease. Patients were restrictively included in the urgent TAVI registry if they were admitted with acute refractory and persistent HF despite medical therapy and had TAVI performed during the same hospital stay. All others were included in the elective TAVI group. Between November 2008 and April 2015, 410 consecutive patients underwent TAVI at our centre-27 (6.6%) urgently. Patients operated on urgently were more likely to be frail and carry higher SAVR mortality risk based on The Society of Thoracic Surgeons Predicted Risk of Mortality/logistic EuroSCORE (LES) measures. Pulmonary edema was the most common clinical presentation. Preprocedural assessment used fewer imaging modalities, yet implantation success remained high and reached 96.3% using an additional valve (valve-within-valve) required in 3 patients, with no difference in periprocedural complications according to the Valve Academic Research Consortium-2 definitions. Although 30-day functional capacity was reduced, patients had similar 30-day mortality and major adverse cardiovascular event rates compared with patients who underwent elective TAVI. Short-term outcome after urgent TAVI appears to be reasonable. For patients with severe AS who experience acute decompensated HF that is recalcitrant to optimal medical therapy and who are at high risk with SAVR, urgent TAVI may be a viable treatment strategy. Larger prospective studies and data on long-term outcomes are needed. Copyright © 2016 Canadian Cardiovascular Society. Published by Elsevier Inc. All rights reserved.

    β-Blocker therapy has been shown to improve survival among patients with ischaemic heart disease (IHD) and congestive heart failure (CHF) and is underused among patients with chronic obstructive pulmonary disease (COPD). Evidence regarding the optimal use of β-blocker therapy during an acute exacerbation of COPD is particularly weak. We conducted a retrospective cohort study of patients aged ≥40 years with IHD, CHF or hypertension who were hospitalised for an acute exacerbation of COPD from 1 January 2006 to 1 December 2007 at 404 acute care hospitals throughout the USA. We examined the association between β-blocker therapy and in-hospital mortality, initiation of mechanical ventilation after day 2 of hospitalisation, 30-day all-cause readmission and length of stay. Of 35 082 patients who met the inclusion criteria, 29% were treated with β blockers in the first two hospital days, including 22% with β1-selective and 7% with non-selective β blockers. In a propensity-matched analysis, there was no association between β-blocker therapy and in-hospital mortality (OR 0.88, 95% CI 0.71 to 1.09), 30-day readmission (OR 0.96, 95% CI 0.89 to 1.03) or late mechanical ventilation (OR 0.98, 95% CI 0.77 to 1.24). However, when compared with β1 selective β blockers, receipt of non-selective β blockers was associated with an increased risk of 30-day readmission (OR 1.25, 95% CI 1.08 to 1.44). Among patients with IHD, CHF or hypertension, continuing β1-selective β blockers during hospitalisation for COPD appears to be safe. Until additional evidence becomes available, β1-selective β blockers may be superior to treatment with a non-selective β blocker.

    Obesity is known to be associated with the development of heart failure (HF). However, the relationship between the body mass index (BMI) and acute HF (AHF) remains to be elucidated. Eight hundred and eight AHF patients were enrolled in this study. The patients were assigned to four groups according to their BMI values: severely thin (n = 11, BMI valvular disease than normal/underweight patients. The patients in the overweight group were significantly younger than those in the normal/underweight, and those in the overweight group were more likely to have SBP ≥140 mmHg and hypertensive heart disease and less likely to have valvular disease than the patients in the normal/underweight group. The prognosis, including all-cause death, was significantly poorer among patients who were severely thin than those who were normal/underweight, overweight and significantly better among those who were overweight than those who were normal/underweight, severely thin and obese patients. A multivariate Cox regression model identified that severely thin [HR: 3.372, 95% confidence interval (CI) 1.362-8.351] and overweight (HR: 0.615, 95% CI 0.391-0.966) were independent predictors of 910-day mortality as the reference of normal/underweight. Overweight patients tended to have SBP ≥140 mmHg and be relatively young, while severely thin patients tended to have SBP <100 mmHg and be female. These factors were associated with a better prognosis of overweight patients and adverse outcomes in severely thin patients. These factors may contribute to the "obesity paradox" in severely decompensated AHF patients.

    The purpose of the study is to evaluate the number of patients with heart failure readmitted for renal failure to IU Health Bloomington within 30 days of hospital discharge in 2010, and to determine whether there are factors that might have been identified before the original discharge that would have prevented the readmission. The goal of the research is to identify factors from previous admissions of patients with heart failure that would have possibly predicted a subsequent admission for renal failure, so that interventions can be developed to prevent such readmissions. The results from this study are applicable to all primary care settings. A retrospective descriptive design was employed. Subjects were patients diagnosed with heart failure in 2010 and subsequently readmitted with renal failure within 30 days of their previous hospital admission. A retrospective chart review was completed extracting the variables blood urea nitrogen levels upon patients' discharge and readmission, serum creatinine levels upon discharge and readmission, weight in kilograms upon discharge and readmission, total intake and output during the first hospitalization, diuretic medication dosage, history of renal failure, history of renal insufficiency, and death. Renal failure may be a predictable complication of heart failure. Although there are varying secondary pathophysiologies, which could account for readmission with renal failure and the severity of the renal failure, more attention should be paid to the variables identified in this study. Case managers can play a crucial role in identifying potential patients with renal failure and, where possible, collaborating with other health care providers to proactively preventing renal complications in patients with heart failure.

    Hyponatremia (HN) occurs commonly in patients with acute heart failure and confers a worse prognosis. Current HN treatment varies widely, with no consensus. This study recorded treatment practices currently used for patients hospitalized with acute heart failure and HN. Data were collected prospectively from 146 US sites on patients hospitalized with acute heart failure and HN (serum sodium concentration [Na(+)] ≤130 mEq/L) present at admission or developing in the hospital. Baseline variables, HN treatment, and laboratory values were recorded. Of 762 patients, median [Na(+)] was 126 mEq/L (interquartile range, 7) at baseline and increased to 130 mEq/L at discharge. Fluid restriction was the most commonly prescribed therapy (44%), followed by no specific HN treatment beyond therapy for congestion (23%), isotonic saline (5%), tolvaptan (4%), and hypertonic saline (2%). Median rate of change in [Na(+)] varied by treatment (0.5 [interquartile range, 1.0] to 2.3 [8.0] mEq/L/d) and median treatment duration ranged from 1 (interquartile range, 1) to 6 (5) days. Fluid restriction and no specific HN treatment resulted in similar changes in [Na(+)], and were least effective in correcting HN. Few patients (19%) had [Na(+)] ≥135 mEq/L at discharge. The most commonly used treatment approaches for HN (fluid restriction and no specific treatment) in acute heart failure increased [Na(+)] minimally, and most patients remained hyponatremic at discharge. © 2017 The Authors.

    Renal impairment and fluctuations in renal function are common in patients recently hospitalized for acute heart failure and in those with atrial fibrillation. The aim of the present study was to evaluate the hypothetical need for dosage adjustment (based on fluctuations in kidney function) of dabigatran, rivaroxaban and apixaban during the first 6 months after hospital discharge in patients with concomitant atrial fibrillation and heart failure. An observational study was conducted in 162 patients with nonvalvular atrial fibrillation after hospitalization for acute decompensated heart failure who underwent creatinine determinations during follow-up. The hypothetical recommended dosage of dabigatran, rivaroxaban and apixaban according to renal function was determined at discharge. Variations in serum creatinine and creatinine clearance and consequent changes in the recommended dosage of these drugs were identified during 6 months of follow-up. Among the overall study population, 44% of patients would have needed dabigatran dosage adjustment during follow-up, 35% would have needed rivaroxaban adjustment, and 29% would have needed apixaban dosage adjustment. A higher proportion of patients with creatinine clearance renal impairment. Further studies are needed to clarify the clinical importance of these needs for drug dosing adjustment and the ideal renal function monitoring regime in heart failure and other subgroups of patients with atrial fibrillation.

    2015-01-01

    This review article addresses the question of whether biomarker-guided therapy is ready for clinical implementation in chronic heart failure. The most well-known biomarkers in heart failure are natriuretic peptides, namely B-type natriuretic peptide (BNP) and N-terminal pro-BNP. They are well-established in the diagnostic process of acute heart failure and prediction of disease prognosis. They may also be helpful in screening patients at risk of developing heart failure. Although studied by 11 small- to medium-scale trials resulting in several positive meta-analyses, it is less well-established whether natriuretic peptides are also helpful for guiding chronic heart failure therapy. This uncertainty is expressed by differences in European and American guideline recommendations. In addition to reviewing the evidence surrounding the use of natriuretic peptides to guide chronic heart failure therapy, this article gives an overview of the shortcomings of the trials, how the results may be interpreted and the future directions necessary to fill the current gaps in knowledge. Therapy guidance in chronic heart failure using other biomarkers has not been prospectively tested to date. Emerging biomarkers, such as galectin-3 and soluble ST2, might be useful in this regard, as suggested by several post-hoc analyses. PMID:28785440

    The hemodynamic effects of digoxin (0.01 mg/Kg) on congestive heart failure were compared in 32 patients with old myocardial infarction (OMI) (n = 9), dilated cardiomyopathy (DCM) (n = 10), acute myocardial infarction (AMI) (n = 5) and mitral stenosis (MS) (n = 8). The responses of heart rate (HR) and pulmonary capillary pressure (PCP) to digoxin in OMI, DCM and MS were marked but different in each of these groups and no significant changes were found in patients with AMI. The responses of cardiac index (CI) to digoxin in patients with OMI and DCM in whom left ventricular myocardial contractile force was impaired were divided into 2 groups (Group 1: CI increased more than 15% and Group 2: less than 15%). In Group 1, both CI and percent fractional shortening (%FS) before digoxin administration were lower than in Group 2, i.e., 1.97 +/- 0.27 vs 2.80 +/- 0.48 L/min/m2 (p less than 0.001) and 10.9 +/- 8.0 vs 19.5 +/- 11.9% (p less than 0.05), respectively. In MS, CI increased after digoxin administration only in the 2 patients with low CI and rapid HR in the control state. These results indicate that the mode of hemodynamic response to digoxin is considerably different in various diseases. They further suggest that digoxin should not be used in the early phase of AMI, although digoxin was of great clinical benefit in patients with OMI and DCM through such mechanisms as its positive inotropic and negative chronotropic effects and lowering of PCP.

    The need for a central venous catheter has limited the widespread use of ultrafiltration in daily clinical practice for the treatment of acute heart failure (AHF) with overt fluid overload. We evaluated the feasibility of a new ultrafiltration device, the CHIARA (Congestive Heart Impairment Advanced Removal Approach) system, that utilizes a single-lumen cannula (17G, multi-hole) inserted in a peripheral vein of the arm. In this multicenter, prospective, feasibility study, consecutive ultrafiltration treatments (lasting ≥6 hours and with an ultrafiltration rate ≥100ml/h) with the CHIARA device and a single peripheral venous approach were performed at 6 Italian hospitals. For each session, we evaluated the performance of the venous access, the ultrafiltrate volume removed, and the cause of its interruption. One-hundred-three ultrafiltration sessions were performed in 55 patients with AHF (average 1.9±1.7 treatment/patient). The overall median length of ultrafiltration treatment was 14h (interquartile range 7-21) with removal of 3266±3088ml of fluid (183±30ml/hour). The treatment was successfully completed in 92 (89%) sessions and in 80% of patients. The mean suction flow rate from the vein was 70±20ml/min, while the mean re-injection flow rate was 98±26ml/min. There were no clinically relevant complications related to the venous access and/or to the anticoagulant therapy with heparin. The study demonstrated that the CHIARA system satisfies clinical applicability and efficacy criteria in the treatment of AHF, in terms of adequate fluid removal through a single peripheral venous access.

    Although neurohumoral antagonism has successfully reduced heart failure morbidity and mortality, the residual disability and death rate remains unacceptably high. Though abnormalities of myocardial metabolism are associated with heart failure, recent data suggest that heart failure may itself promote metabolic changes such as insulin resistance, in part through neurohumoral activation. A detrimental self-perpetuating cycle (heart failure --> altered metabolism --> heart failure) that promotes the progression of heart failure may thus be postulated. Accordingly, we review the cellular mechanisms and pathophysiology of altered metabolism and insulin resistance in heart failure. It is hypothesized that the ensuing detrimental myocardial energetic perturbations result from neurohumoral activation, increased adverse free fatty acid metabolism, decreased protective glucose metabolism, and in some cases insulin resistance. The result is depletion of myocardial ATP, phosphocreatine, and creatine kinase with decreased efficiency of mechanical work. On the basis of the mechanisms outlined, appropriate therapies to mitigate aberrant metabolism include intense neurohumoral antagonism, limitation of diuretics, correction of hypokalemia, exercise, and diet. We also discuss more novel mechanistic-based therapies to ameliorate metabolism and insulin resistance in heart failure. For example, metabolic modulators may optimize myocardial substrate utilization to improve cardiac function and exercise performance beyond standard care. The ultimate success of metabolic-based therapy will be manifest by its capacity further to lessen the residual mortality in heart failure.

    To identify an approach to summarizing publicly reported hospital performance data for acute myocardial infarction (AMI) or heart failure (HF) that best predicts current year hospital mortality rates. A total of 1,868 U.S. hospitals reporting process and outcome measures for AMI and HF to the Centers for Medicare and Medicaid Services (CMS) from July 2005 to June 2006 (Year 0) and July 2006 to June 2007 (Year 1). Observational cohort study measuring the percentage variation in Year 1 hospital 30-day risk-adjusted mortality rate explained by denominator-based weighted composite scores summarizing hospital Year 0 performance. Data were prospectively collected from hospitalcompare.gov. Percentage variation in Year 1 mortality was best explained by mortality rate alone in Year 0 over other composites including process performance. If only Year 0 mortality rates were reported, and consumers using hospitals in the highest decile of mortality instead chose hospitals in the lowest decile of mortality rate, the number of deaths at 30 days that potentially could have been avoided was 1.31 per 100 patients for AMI and 2.12 for HF (p < .001). Public reports focused on 30-day risk-adjusted mortality rate may more directly address policymakers' goals of facilitating consumer identification of hospitals with better outcomes. © 2011 National Association for Healthcare Quality.

    This study sought to define the relationship between body mass index (BMI) and mortality in heart failure (HF) across the world and to identify specific groups in whom BMI may differentially mediate risk. Obesity is associated with incident HF, but it is paradoxically associated with better prognosis during chronic HF. We studied 6,142 patients with acute decompensated HF from 12 prospective observational cohorts followed-up across 4 continents. Primary outcome was all-cause mortality. Cox proportional hazards models and net reclassification index described associations of BMI with all-cause mortality. Normal-weight patients (BMI 18.5 to 25 kg/m(2)) were older with more advanced HF and lower cardiometabolic risk. Despite worldwide heterogeneity in clinical features across obesity categories, a higher BMI remained associated with decreased 30-day and 1-year mortality (11% decrease at 30 days; 9% decrease at 1 year per 5 kg/m(2); p 75 years; hazard ratio [HR]: 0.82; p = 0.006), decreased cardiac function (ejection fraction obesity paradox" is confined to older persons, with decreased cardiac function, less cardiometabolic illness, and recent-onset HF, suggesting that aging, HF severity/chronicity, and metabolism may explain the obesity paradox.

    Treatment of acute decompensated heart failure (ADHF) with loop diuretics, such as furosemide, is frequently complicated by insufficient urine sodium excretion. We hypothesize that insufficient natriuretic response to diuretic therapy, characterized by lower urine sodium (UNa) and urine furosemide, is associated with subsequent inadequate decongestion, worsening renal function, and adverse long term events. We enrolled 52 consecutive patients with ADHF and measured serum and urine sodium (UNa), urine creatinine (UCr), and urine furosemide (UFurosemide) levels on a spot sample taken after treatment with continuous intravenous furosemide, and followed clinical and renal variables as well as adverse long-term clinical outcomes (death, rehospitalizations, and cardiac transplantation). We observed similar correlations between UNa:UFurosemide ratio and UNa and fractional excretion of sodium (FENa) with 24-hour net urine output (r = 0.52-0.64, all P furosemide were observed when UNa:UFurosemide ratios were furosemide infusion, impaired natriuretic response to furosemide is associated with greater likelihood of worsening renal function and future adverse long-term outcomes, independently from and incrementally with decreasing intrinsic glomerular filtration.

    Full Text Available Pulmonary veno-occlusive disease (PVOD is rare condition which can lead to severe pulmonary hypertension, right ventricular dysfunction, and cardiopulmonary failure. The diagnosis of PVOD can be challenging due to its nonspecific symptoms and its similarity to idiopathic pulmonary arterial hypertension and interstitial lung disease in terms of diagnostic findings. This case describes a 57 year old female patient who presented with a 5-month history of progressive dyspnea on exertion and nonproductive cough. Workup at another hospital was nonspecific and the patient underwent surgical lung biopsy due to concern for interstitial lung disease. She subsequently became hemodynamically unstable and was transferred to our hospital where she presented with severe hypoxemia, hypotension, and suprasystemic pulmonary artery pressures. Preliminary lung biopsy results suggested idiopathic pulmonary arterial hypertension and the patient was started on vasodilating agents, including continuous epoprostenol infusion. Pulmonary artery pressures decreased but remained suprasystemic and the patient did not improve. Final review of the biopsy by a specialized laboratory revealed a diagnosis of PVOD after which vasodilating therapy was immediately weaned off. Evaluation for dual heart-lung transplantation was begun. The patient's hospital course was complicated by hypotension requiring vasopressors, worsening right ventricular dysfunction, and acute kidney injury. During the transplantation evaluation, the patient decided that she did not want to undergo continued attempts at stabilization of her progressive multi-organ dysfunction and she was transitioned to comfort care. She expired hours after removing inotropic support.

    To assess the impact of comorbidities on long-term all-cause mortality in patients hospitalized with exacerbated signs/symptoms of previously chronic stable HF (AE-CHF). 1119 patients admitted for AE-CHF and with NT-proBNP levels >900pg/mL were enrolled. Univariable and multivariable Cox analyses were performed to assess the association of age, gender, hypertension, diabetes, obesity, atrial fibrillation, coronary heart disease (CHD), chronic obstructive pulmonary disease, previous cerebrovascular accidents, chronic liver disease (CLD), thyroid disease, renal impairment (RI), and anemia with 3-year all-cause mortality. During the follow-up, 441 patients died and 126 underwent heart transplantation (HT) or ventricular assist device (VAD) implantation. 45.8% of the fatal events and 52.4% of HT/VAD implantations occurred within 180days after admission. Increasing age (p=.012), obesity (p=.037), atrial fibrillation (p=.030), CHD (p=.015), CLD (p=.001), RI (phospitalized patients with worsening HF, although the nature of this association does appear to be complex.

    The blood urea nitrogen-to-creatinine (BUN/creatinine) ratio has been proposed as a useful parameter in acute heart failure (AHF), but data on the normal range and the added value of the ratio compared with its separate components in patients with AHF are lacking. The aim of this study is to define the normal range of BUN/creatinine ratio and to investigate its clinical significance in patients with AHF. In 4484 subjects from the general population without cardiovascular comorbidities, we calculated age-specific and sex-specific normal values of the BUN/creatinine ratio, deriving a higher and lower than normal range of BUN/creatinine ratio (exceeding the 95% prediction intervals). Association of abnormal range to prognosis was tested in 2033 patients with AHF for the outcome of all-cause death through 180 days, death or cardiovascular or renal rehospitalisation through 60 days and heart failure (HF) rehospitalisation within 60 days. In a cohort of patients with AHF, 482 (24.6%) and 28 (1.4%) patients with HF were classified into higher and lower than normal range groups, respectively. In Cox regression analysis, higher than normal range of BUN/creatinine ratio group was an independent predictor for all-cause death (HR: 1.86, 95% CI 1.29 to 2.66) and death or cardiovascular or renal rehospitalisation (HR: 1.37, 95% CI 1.03 to 1.82), but not for HF rehospitalisation (HR: 1.23, 95% CI 0.81 to 1.86) after adjustment for other prognostic factors including both creatinine and BUN. In patients with AHF, BUN/creatinine higher than age-specific and sex-specific normal range is associated with worse prognosis independently from both creatinine and BUN.

    Elevated red blood cell distribution width (RDW) is a valid predictor of outcome in acute heart failure (AHF). It is unknown whether elevated RDW remains predictive in AHF patients with either preserved left ventricular ejection fraction (LVEF) ≥50% or reduced LVEF (<50%). Prospective local registry including 402 consecutive hospitalized AHF patients without acute coronary syndrome or need of intensive care. The primary outcome was all-cause mortality (ACM) at 1 year after admission. Demographic and clinical data derive from admission, echocardiographic examinations (n = 269; 67%) from hospitalization. The Cox proportional hazard model including all patients (P < 0.001) was adjusted for age, gender, and RDW quartiles. Independent predictors of 1-year ACM were cardiogenic shock (HR 2.86; CI: 1.3-6.4), male sex (HR 1.9; CI: 1.2-2.9), high RDW quartile (HR 1.66; CI: 1.02-2.8), chronic HF (HR 1.61; CI: 1.05-2.5), valvular heart disease (HR 1.61; CI: 1.09-2.4), increased diastolic blood pressure (HR 1.02 per mmHg; CI: 1.01-1.03), increasing age (HR 1.04 by year; CI: 1.02-1.07), platelet count (HR 1.002 per G/l; CI: 1.0-1.004), systolic blood pressure (HR 0.99 per mmHg; CI: 0.98-0.99), and weight (HR 0.98 per kg; CI: 0.97-0.99). A total of 114 patients (28.4%) died within the first year; ACM of all patients increased with quartiles of rising RDW (χ2 18; P < 0.001). ACM was not different between RDW quartiles of patients with reduced LVEF (n = 153; χ2 6.6; P = 0.084). In AHF with LVEF ≥50% the probability of ACM increased with rising RDW (n = 116; χ2 9.9; P = 0.0195). High RDW is associated with increased ACM in AHF patients with preserved but not with reduced LVEF in this study population.

    Full Text Available We present the case of a 51-year-old male patient who received adjuvant chemotherapy consisting of oxaliplatin, bolus and continuous 5-fluorouracil (5-FU and leucovorin after anterior resection because of locally advanced rectal cancer. Preoperative chemotherapy with capecitabine (an oral 5-FU prodrug had been well tolerated. Two days after initiation of the first course of chemotherapy, the patient reported typical chest pain. The ECG showed ST elevations and prominent T waves in almost all leads. Due to suspicion of a high-risk acute coronary syndrome, an urgent cardiac catheterization was performed. It showed a generally reduced coronary flow with multiple significant stenoses (including the ostia of the left and right coronary artery, as well as a highly reduced left ventricular function with diffuse hypokinesia. Due to the meanwhile completely stable situation of the patient after medical acute coronary syndrome treatment, no ad hoc intervention was performed to allow further discussion of the optimal management. Thereafter, the patient remained clinically asymptomatic, without any rise in cardiac necrosis parameters; only NT-pro-BNP was significantly elevated. A control cardiac catheterization 2 days later revealed a restored normal coronary artery flow with only coronary calcifications without significant stenoses, as well as a normal left ventricular ejection fraction. Cardiovascular symptoms occurred on the second day of continuous 5-FU treatment. As cardiotoxic effects seem to appear more frequently under continuous application of 5-FU, compared to the earlier established 5-FU bolus regimens, treating medical oncologists should pay special attention to occurring cardiac symptoms and immediately interrupt 5-FU chemotherapy and start a cardiologic work-up.

    The impact of gender on the clinical characteristics, risk factors, co-morbidities, etiology, treatment and outcome of acute heart failure in sub-Saharan Africa has not been described before. The aim of this study was to evaluate the sex differences in acute heart failure in sub-Saharan Africa using the data from The sub-Saharan Africa Survey of Heart Failure (THESUS-HF). 1,006 subjects were recruited into this prospective multicenter, international observational heart failure survey. The mean age of total population was 52.4 years (54.0 years for men and 50.7 years for women). The men were significantly older (p = 0.0045). Men also presented in poorer NYHA functional class (III and IV), p = 0.0364). Cigarette smoking and high blood pressure were significantly commoner in men (17.3 vs. 2.6% and 60.0 vs. 51.0% respectively). On the other hand, atrial fibrillation and valvular heart disease were significantly more frequent in women. The mean hemoglobin concentration was lower in women compared to men (11.7 vs. 12.6 g/dl, p ≤ 0.0001), while the blood urea and creatinine levels were higher in men (p < 0.0001). LV systolic dysfunctional was also seen more in men. Men also had higher E/A ratio indicating higher LV filling pressure. Outcomes were similar in both sexes. Although the outcome of patients admitted for AHF in sub-Saharan regions is similar in men and women, some gender differences are apparent suggesting that in men more emphasis should be put on modifiable life risk factors, while in women prevention of rheumatic heart diseases and improved nutrition should be addressed vigorously.

    The reduction of exercise capacity with early occurrence of fatigue and dyspnea is a hallmark of heart failure syndrome. There are objective similarities between heart failure and muscular deconditioning. Deficiencies in peripheral blood flow and skeletal muscle function, morphology, metabolism, and function are present. The protective effects of physical activity have been elucidated in many recent studies: training improves ventilatory control, skeletal muscle metabolism, autonomic nervous system, central and peripheral circulation, and heart function. These provide the physiologic basis to explain the benefits in terms of survival and freedom from hospitalization demonstrated by physical training also in heart failure.

    Epidemiologic and clinical data from the last 2 decades have shown that the prevalence of heart failure in diabetes is very high, and the prognosis for patients with heart failure is worse in those with diabetes than in those without diabetes. Experimental data suggest that various mechanisms contribute to the impairment in systolic and diastolic function in patients with diabetes, and there is an increased recognition that these patients develop heart failure independent of the presence of coronary artery disease or its associated risk factors. In addition, current clinical data demonstrated that treatment with the sodium glucose cotransporter 2 inhibitor empagliflozin reduced hospitalization for heart failure in patients with type 2 diabetes mellitus and high cardiovascular risk. This review article summarizes recent data on the prevalence, prognosis, pathophysiology, and therapeutic strategies to treat patients with diabetes and heart failure. Copyright © 2017 The Authors.

    Accurate documentation of preferences for cardiopulmonary resuscitation at hospital admission is critical to ensure that patients receive resuscitation or not in accordance with their wishes. We sought to identify and characterize inconsistencies in patient-reported and clinician-ordered resuscitation status in patients hospitalized with acute decompensated heart failure (ADHF). Southeastern Minnesota residents hospitalized with ADHF were prospectively enrolled into a study that included the administration of face-to-face questionnaires from January 2014 to February 2016. Patient-reported resuscitation status was assessed at enrollment using a validated question. Clinician-ordered resuscitation preferences at hospital admission were abstracted from the electronic medical record. Of the 400 patients administered the questionnaire; 213 (53.3%) stated their resuscitation preference as Full Code, 166 (41.5%) do-not-resuscitate (DNR), and 21 (5.3%) were unsure. In comparison, clinician-ordered resuscitation status was Full Code in 263 (65.8%) patients, DNR in 133 (33.3%), and not documented in four (1.0%). Patient-reported and clinician-ordered resuscitation status was discordant in 20% of patients, of whom 5.6% elected Full Code by questionnaire and had a DNR clinician order, and 14.4% elected DNR by questionnaire but had a Full Code clinician order. Differences in age, comorbidities, health literacy, marital status, completion of advance directives, hospital length of stay, and discharge destination in patients with discordant vs. concordant resuscitation preferences were observed. Patient-reported and clinician-ordered resuscitation preferences were discordant in 20% of patients hospitalized with ADHF. The underlying etiology of these inconsistencies may reflect factors such as patient indecisiveness or patient-clinician miscommunication and requires further exploration.

    This study sought to evaluate the effects of beta-blocker withdrawal in acute decompensated heart failure (ADHF). Published reports showed trends for either no harm or increased risk of in-hospital mortality, short-term mortality, and rehospitalization rates in patients admitted for ADHF that discontinued beta-blockers; however, a comprehensive analysis has not been conducted. Relevant studies from January 2000 through January 2015 were identified in the PubMed, EMBASE, and COCHRANE electronic databases. Where appropriate data were available, weighted relative risks were estimated using random-effects meta-analysis techniques. Five observational studies and 1 randomized clinical trial (n = 2,704 patients who continued beta-blocker therapy and n = 439 patients who discontinued beta-blocker therapy) that reported the short-term effects of beta-blocker withdrawal in ADHF were included in the analyses. In 2 studies, beta-blocker withdrawal significantly increased risk of in-hospital mortality (risk ratio: 3.72; 95% confidence interval [CI]: 1.51 to 9.14). Short-term mortality (relative risk: 1.61; 95% CI: 1.04 to 2.49; 4 studies) and combined short-term rehospitalization or death (relative risk: 1.59; 95% CI: 1.03 to 2.45; 4 studies) were also significantly increased. Discontinuation of beta-blockers in patients admitted with ADHF was associated with significantly increased in-hospital mortality, short-term mortality, and the combined endpoint of short-term rehospitalization or mortality. These data suggest beta-blockers should be continued in ADHF patients if their clinical picture allows. Copyright © 2015 American College of Cardiology Foundation. Published by Elsevier Inc.

    The optimal treatment of patients with acute heart failure (AHF) and cardiorenal syndrome type 1 (CRS-1) is far from being well-defined. Arterial hypoperfusion in concert with venous congestion plays a crucial role in the pathophysiology of CRS-I. Plasma carbohydrate antigen 125 (CA125) has emerged as a surrogate of fluid overload in AHF. The aim of this study was to evaluate the clinical usefulness of CA125 for tailoring the intensity of diuretic therapy in patients with CRS-1. Multicenter, open-label, parallel clinical trial, in which patients with AHF and serum creatinine ≥ 1.4mg/dL on admission will be randomized to: a) standard diuretic strategy: titration-based on conventional clinical and biochemical evaluation, or b) diuretic strategy based on CA125: high dose if CA125 > 35 U/mL, and low doses otherwise. The main endpoint will be renal function changes at 24 and 72hours after therapy initiation. Secondary endpoints will include: a) clinical and biochemical changes at 24 and 72hours, and b) renal function changes and major clinical events at 30 days. The results of this study will add important knowledge on the usefulness of CA125 for guiding diuretic treatment in CRS-1. In addition, it will pave the way toward a better knowledge of the pathophysiology of this challenging situation. We hypothesize that higher levels of CA125 will identify a patient population with CRS-1 who could benefit from the use of a more intense diuretic strategy. Conversely, low levels of this glycoprotein could select those patients who would be harmed by high diuretic doses. Copyright © 2017 Sociedad Española de Cardiología.

    The changes in renal function that occurred in patients with acute decompensated heart failure (ADHF) are prevalent, and have multifactorial etiology and dissimilar prognosis. To what extent the prognostic role of such changes may vary according to the presence of renal insufficiency at admission is not clear. Accordingly, we sought to determine whether early creatinine changes (ΔCr) (admission to 48-72 hours) had an effect on 1-year mortality relative to the presence of renal insufficiency at admission. We included 705 consecutive patients admitted with the diagnosis of ADHF. Admission renal insufficiency was defined as serum creatinine ≥1.4mg/dl (A-RI cr ) or estimated glomerular filtration rate renal insufficiency (24.7% and 42.8% for A-RIcr and A-RIGFR, respectively) had higher prevalence of extreme values in ΔCr in either direction (increasing/decreasing). At 1-year follow-up, 114 (16.2%) deaths were registered. The multivariable analysis showed a significant interaction between admission renal insufficiency and ΔCr ( p=0.004 and p=0.019 for A-RIcr and A-RIGFR, respectively). In the presence of renal insufficiency, the continuum of ΔCr followed a positive and almost linear relationship with mortality risk. Conversely, in patients without renal insufficiency, those changes adopted a 'J-shape' trajectory with increased mortality at both ends of the curve distribution. In patients with ADHF the effect of ΔCr on 1-year mortality varied according to its magnitude and the presence of admission renal insufficiency. There was a graded-association with mortality when renal insufficiency was present on admission.

    Diuretics are essential for treating acute decompensated heart failure (ADHF), but the response is inconsistent. This study aimed to clarify whether kidney volume as assessed by ultrasound (US) predicts diuretic resistance in patients with ADHF. We enrolled 29 patients with ADHF and 32 controls. Height-adjusted kidney volume was assessed by US. We divided patients into two groups based on the median value of total daily use of furosemide (intravenous dose plus 0.5 × oral dose of furosemide equivalents) during 3 days from admission. Patients with ADHF had a significantly smaller left kidney volume than did control subjects (27.7 ± 10.0 vs. 32.8 ± 8.8 mL/m, P < 0.05). Patients in the high-dose furosemide group (≥ 51.7 mg/d) had a significantly lower estimated glomerular filtration rate (eGFR) and a significantly smaller kidney volume than did those in the low-dose furosemide group (eGFR: 43.9 ± 20.4 vs. 60.8 ± 21.6 mL/min/1.73 m2, left kidney volume: 23.2 ± 5.2 vs. 32.6 ± 11.0 mL/m, right kidney volume: 26.5 ± 7.5 vs. 32.6 ± 7.9 mL/m, all P < 0.05). Multivariate logistic analysis showed that left kidney volume, but not eGFR, was independently associated with the requirement of high-dose furosemide (odds ratio: 0.856, 95% confidence interval: 0.735-0.997, P < 0.05). Kidney volume as assessed by US is a useful predictor of diuretic resistance in patients with ADHF.

  9. Is there a clinically meaningful difference in patient reported dyspnea in acute heart failure? An analysis from URGENT Dyspnea.

    Dyspnea is the most common presenting symptom in patients with acute heart failure (AHF), but is difficult to quantify as a research measure. The URGENT Dyspnea study compared 3 scales: (1) 10 cm VAS, (2) 5-point Likert, and (3) a 7-point Likert (both VAS and 5-point Likert were recorded in the upright and supine positions). However, the minimal clinically important difference (MCID) to patients has not been well established. We performed a secondary analysis from URGENT Dyspnea, an observational, multi-center study of AHF patients enrolled within 1 h of first physician assessment in the ED. Using the anchor-based method to determine the MCID, a one-category change in the 7-point Likert was used as the criterion standard ('minimally improved or worse'). The main outcome measures were the change in visual analog scale (VAS) and 5-point Likert scale from baseline to 6-h assessment relative to a 1-category change response in the 7-point Likert scale ('minimally worse', 'no change', or 'minimally better'). Of the 776 patients enrolled, 491 had a final diagnosis of AHF with responses at both time points. A 10.5 mm (SD 1.6 mm) change in VAS was the MCID for improvement in the upright position, and 14.5 mm (SD 2.0 mm) in the supine position. However, there was no MCID for worsening, as few patients reported worse dyspnea. There was also no significant MCID for the 5-point Likert scale. A 10.5 mm change is the MCID for improvement in dyspnea over 6 h in ED patients with AHF. Copyright © 2017 Elsevier Inc. All rights reserved.

    Introduction The objective of this study was to compare the emergency department (ED) management and rate of admission of acute decompensated heart failure (ADHF) between two hospitals in Canada and the United States and to compare the outcomes of these patients. This was a health records review of adults presenting with ADHF to two EDs in Canada and the United States between January 1 and April 30, 2010. Outcome measures were admission to the hospital, myocardial infarction (MI), and death or relapse rates to the ED. Data were analysed using descriptive, univariate and multivariate analyses. In total, 394 cases were reviewed and 73 were excluded. Comparing 156 Canadian to 165 U.S. patients, respectively, mean age was 76.0 and 75.8 years; male sex was 54.5% and 52.1%. Canadian and U.S. ED treatments were noninvasive ventilation 7.7% v. 12.8% (p=0.13); IV diuretics 77.6% v. 36.0% (p3.0 hours, p<0.001). Proportion of Canadian and U.S. patients who died within 30 days of the ED visit was 5.1% v. 9.7% (p=0.12); relapsed to the ED within 30 days was 20.8% v. 17.5% (p=0.5); and had MI within 30 days was 2.0% v. 1.9% (p=1.0). The U.S. and Canadian centres saw ADHF patients with similar characteristics. Although the U.S. site had almost double the admission rate, the outcomes were similar between the sites, which question the necessity of routine admission for patients with ADHF.

    To assess the utility of measuring the diameter and collapse of the inferior vena cava (IVC) in acute heart failure (AHF), its relationship with the prognosis and serum biomarkers of congestion. An observational prospective study was conducted that included 85 patients with AHF, classifying them into 4 groups according to IVC diameter (≤ or >20mm) and inspiratory collapse (< or ≥50%) at admission. The endpoints were mortality due to HF and the combined event of mortality and readmission for HF at 180 days. Some 24.7% of the patients had an undilated IVC and ≥50% collapse (group 1); 20% had an undilated IVC and <50% collapse (group 2), 5.9% had a dilated IVC and ≥50% collapse (group 3); and 49.4% had a dilated IVC and <50% collapse (group 4). The lack of inspiratory collapse but not IVC dilation was related to higher concentrations of urea (P=.007), creatinine (P=.004), uric acid (P=.008), NT-proBNP (P=.009) and CA125 (P=.005). Survival free of the combined event at 180 days was lower in those patients with no IVC collapse. Dilation and the absence of the inspiratory collapse of the IVC are common in the context of AHF. The lack of inspiratory collapse of the IVC during the decompensation phase identifies a subgroup of patients with poorer prognosis at 6 months.

    Conflicting renal effects of nesiritide have been reported in patients with acute decompensated heart failure. To answer this controversy, we performed a meta-analysis of randomized controlled trials to evaluate the influence of nesiritide on renal function in patients with acute decompensated heart failure. Articles were obtained from PubMed, Medline, Cochrane Library and reference review. Randomized controlled studies that investigated the effects of continuous infusion of nesiritide on renal function in adult patients with acute decompensated heart failure were included and analyzed. Fixed-effect model was used to estimate relative risk (RR) and weight mean difference (WMD). The quality assessment of each study, subgroup, sensitivity, and publication bias analyses were performed. Fifteen randomized controlled trials were eligible for inclusion. Most of included studies had relatively high quality and no publication bias was found. Overall, compared to control therapies, nesiritide might increase the risk of worsening renal function in patients with acute decompensated heart failure (RR 1.08, 95% CI 1.01-1.15, P = 0.023). In subgroup analysis, high-dose nesiritide strongly associated with renal dysfunction (RR 1.54, 95% CI 1.19-2.00, P = 0.001), but no statistical differences were observed in standard-dose (RR 1.04, 95% CI 0.98-1.12, P = 0.213), low-dose groups (RR 1.01, 95% CI 0.74-1.37, P = 0.968) and same results were identified in the subgroup analysis of placebo controlled trials. Peak mean change of serum creatinine from baseline was no significant difference (WMD -2.54, 95% CI -5.76-0.67, P = 0.121). In our meta-analysis, nesiritide may have a dose-dependent effect on renal function in patients with acute decompensated heart failure. High-dose nesiritide is likely to increase the risk of worsening renal function, but standard-dose and low-dose nesiritide probably have no impact on renal function. These findings could be helpful to optimize the use of

    In patients with heart failure and type 2 diabetes, low glycosylated hemoglobin has been related with higher risk of mortality but information regarding morbidity is scarce. We sought to evaluate the association between glycosylated hemoglobin and 30-day readmission in patients with type 2 diabetes and acute heart failure. Glycosylated hemoglobin was measured before discharge in 835 consecutive patients with acute heart failure and type 2 diabetes. Cox regression analysis adapted for competing events was used. Mean (standard deviation) age was 72.9 (9.6) years and median glycosylated hemoglobin was 7.2% (6.5%-8.0%). Patients treated with insulin or insulin/sulfonylurea/meglitinides were 41.1% and 63.2% of the cohort, respectively. At 30 days post-discharge, 109 (13.1%) patients were readmitted. A multivariate analysis revealed that the effect of glycosylated hemoglobin on the risk of 30-day readmission was differentially affected by the type of treatment (P for interactiondiabetes (hazard ratio = 1.01; 95% confidence interval, 0.87-1.17; P=.897) or even a positive effect in patients not receiving insulin/sulfonylurea/meglitinides (hazard ratio = 1.12; 95% confidence interval, 1.03-1.22; P=.011). In acute heart failure, glycosylated hemoglobin showed to be inversely associated to higher risk of 30-day readmission in insulin-dependent or those treated with insulin/sulfonylurea/meglitinides. A marginal effect was found in the rest. Whether this association reflects a treatment-related effect or a surrogate of more advanced disease should be clarified in further studies.

    The most common cause of heart failure (HF) is ischemic heart disease (IHD). Evaluation of IHD with non-invasive examinations is useful for the treatment of HF, and cardio-ankle vascular index (CAVI) is a good parameter for detecting systemic arteriosclerosis. However, the relationship between IHD and CAVI in acute HF (AHF) patients is still unclear. Therefore, we investigated the effect of non-invasive examinations, including CAVI to detect IHD. We studied 53 consecutive patients (average age of 66.5 ± 10.9 years old, 36 males) with AHF from January 2009 to December 2012. These patients were classified into the IHD group (n = 19) and non-IHD group (n = 34) according to the coronary artery angiography results. We evaluated the vital signs, laboratory findings and CAVI. According to the laboratory findings, the C-reactive protein (CRP) in IHD group was significantly higher than non-IHD group (1.5 ± 2.1 mg/dL vs. 0.4 ± 0.4 mg/dL, P = 0.002). CAVI in IHD group was significantly higher than non-IHD group (9.58 ± 1.73 vs. 7.83 ± 1.86, P < 0.001). In the receiver operating characteristic (ROC) curve for discriminating the probability of IHD, the cut-off point of the CRP plus CAVI was 9.00. At that cut-off point, the sensitivity and the specificity were 69.7% and 89.5%, respectively. The mean area under the ROC curve (AUC) defined by the CRP plus CAVI was the greatest at all parameters. The CRP and CAVI were useful parameters for the identification of IHD in patients with AHF.

  15. Acute Liver Failure.

    Pediatric acute liver failure (ALF) is a complex and rapidly progressive syndrome that results from a variety of age-dependent etiologies. It is defined by the acute onset of liver disease with no evidence of chronic liver disease. There must be biochemical or clinical evidence of severe liver dysfunction as defined by an international normalized ratio (INR) ≥2. If hepatic encephalopathy is present, INR should be ≥1.5. Unfortunately, due to the rarity of ALF in pediatric patients, there is a paucity of diagnostic and management algorithms and each patient must have an individualized approach.

    Background -Worsening renal function (WRF) in the setting of aggressive diuresis for acute heart failure (AHF) treatment may reflect renal tubular injury or simply indicate a hemodynamic or functional change in glomerular filtration. Well-validated tubular injury biomarkers-NAG, NGAL, and KIM-1- are now available that can quantify the degree of renal tubularinjury. The ROSE-AHF trial provides an experimental platform for the study of mechanisms of WRF during aggressive diuresis for AHF, as the ROSE-AHF protocol dictated high dose loop diuretic therapy in all patients. We sought to determine whether tubular injury biomarkers are associated with WRF in the setting of aggressive diuresis and its association with prognosis. Methods -Patients in the multicenter ROSE-AHF trial with baseline and 72-hour urine tubular injury biomarkers were analyzed ( N =283). WRF was defined as a ≥20% decrease in glomerular filtration rate estimated using cystatin C. Results -Consistent with protocol driven aggressive dosing of loop diuretics, participants received a median 560 mg of IV furosemide equivalents (IQR 300-815 mg) which induced a urine output of 8425 mL (IQR 6341-10528 ml) over the 72-hour intervention period. Levels of NAG and KIM-1 did not change with aggressive diuresis ( P >0.59, both), whereas levels of NGAL decreased slightly [-8.7 ng/mg (-169, 35 ng/mg), P renal tubular injury: NGAL ( P =0.21), NAG ( P =0.46), or KIM-1 ( P =0.22). Increases in NGAL, NAG, and KIM-1 were paradoxically associated with improved survival (adjusted HR: 0.80 per 10 percentile increase, 95% CI: 0.69-0.91; P =0.001). Conclusions -Kidney tubular injury does not appear to have an association with WRF in the context of aggressive diuresis of AHF patients. These findings reinforce the notion that the small to moderate deteriorations in renal function commonly encountered with aggressive diuresis are dissimilar from traditional causes of acute kidney injury.

    Periodontal disease has been associated with an increased risk of cardiovascular events. The purpose of our study was to investigate whether a correlation between periodontitis and chronic heart failure exists, as well as the nature of the underlying cause. We enrolled 71 patients (mean age, 54 ± 13 yr; 56 men) who had stable chronic heart failure; all underwent complete cardiologic and dental evaluations. The periodontal screening index was used to quantify the degree of periodontal disease. We compared the findings to those in the general population with use of data from the 4th German Dental Health Survey. Gingivitis, moderate periodontitis, and severe periodontitis were present in 17 (24%), 17 (24%), and 37 (52%) patients, respectively. Severe periodontitis was more prevalent among chronic heart failure patients than in the general population. In contrast, moderate periodontitis was more prevalent in the general population (P periodontal disease was not associated with the cause of chronic heart failure or the severity of heart failure symptoms. Six-minute walking distance was the only independent predictor of severe periodontitis. Periodontal disease is highly prevalent in chronic heart failure patients regardless of the cause of heart failure. Prospective trials are warranted to clarify the causal relationship between both diseases.

    Although the obesity paradox may vary depending upon clinical background factors such as age, gender, aetiology of heart failure and comorbidities, the reasons underlying the heterogeneous impact of body mass index (BMI) on in-hospital cardiac mortality under various conditions in patients with acute heart failure syndromes (AHFSs) remain unclear. Among 4617 hospitalised patients with AHFSs enrolled in the Acute Decompensated Heart Failure Syndromes (ATTEND) registry, the patient characteristics and in-hospital cardiac mortality rates in those with low BMI (BMI valvular aetiologies and a history of prior hospitalisation for AHFS. The low-BMI group also had lower prevalence rates of diabetes, dyslipidaemia, hypertension and atrial fibrillation and higher prevalence rates of anaemia and chronic obstructive pulmonary disease. In addition, cardiac mortality was significantly higher in the low-BMI group than in the high-BMI group (5.5 vs. 1.5%, p disease and hyponatremia (all p < 0.05), although there were no interactions between the impacts of BMI and age, gender, other aetiologies, prior hospitalisation, diabetes, anaemia, cardio-renal function and in-hospital management. It is necessary to appreciate the obesity paradox in AHFS patients, and a patient's heterogeneous background should also be considered.

    Background More than 25% of Medicare patients hospitalized for heart failure are readmitted within 30 days. The contributions of numeracy and health literacy to recidivism for patients with acute heart failure (AHF) are not known. Methods and Results A cohort of patients with AHF who presented to four emergency departments between January 2008 and September 2011. Research assistants administered subjective measures of numeracy and health literacy; thirty-day follow up was performed by phone interview. Recidivism was defined as any unplanned return to the emergency department or hospital within 30-days of the index emergency department visit for AHF. Multivariable logistic regression adjusting for patient age, gender, race, insurance status, hospital site, days eligible for recidivism, chronic kidney disease, abnormal hemoglobin, and low ejection fraction evaluated the relationships between numeracy and health literacy with 30-day recidivism. Of the 709 patients included in the analysis, 390 (55%) had low numeracy skills and 258 (37%) had low literacy skills. Low numeracy was associated with increased odds of recidivism within 30 days (adjusted odds ratio (OR) 1.41, 95% confidence interval 1.00-1.98, P=0.048). For low health literacy, adjusted OR of recidivism was 1.17 (95% CI 0.83-1.65, P=0.37). Conclusions Low numeracy was associated with greater odds of 30-day recidivism. Further investigation is warranted to determine whether addressing numeracy and health literacy may reduce 30-day recidivism for patients with acute heart failure. PMID:23230305

    Full Text Available Introduction & Objective: Cardiovascular diseases are the main cause of death in all countries in the recent century and congestive heart failure (CHF is the reason of death in most pa-tients . The most common causes of CHF are ischemic heart disease, myopathies , valvular disease and hypertension. Mortality reduction is the aim in CHF treatment. Combination of glucose-insulin-potassium (GIK has been used in the treatment of acute coronary syndrome and chronic CHF for two decades and different results reported. The current study performed to evaluate the efficacy of GIK to accelerate resolving signs and symptoms in patients with acute CHF. Materials & Methods: NT. pro BNP and H.s CRP are two components which increase in acute CHF and decrease after treatment. These parameters were evaluated in our clinical trial study.50 patients admitted with the diagnosis of acute CHF and EF<40% were divided in two groups and the case group received GIK and control group placebo (half saline. Both groups received the classic treatment of CHF and the above mentioned parameters were measured in the first hour and third and fifth day. Results: Appropriate reduction in both parameters, which means good result in treatment, was observed in both groups but without statistical significant difference. Conclusion: GIK has been used with good results in acute MI and chronic heart failure, but in order to prove better efficacy and decrease in mortality in acute CHF more research is needed.

    Acute heart failure is a common reason for admission, and outcome is often poor. Improved prognostic risk stratification may assist in the design of future trials and in patient management. Using data from a large randomized trial, we explored the prognostic value of clinical variables, measured at hospital admission for acute heart failure, to determine whether a few selected variables were inferior to an extended data set. The prognostic model included 37 clinical characteristics collected at baseline in PROTECT, a study comparing rolofylline and placebo in 2033 patients admitted with acute heart failure. Prespecified outcomes at 30 days were death or rehospitalization for any reason; death or rehospitalization for cardiovascular or renal reasons; and, at both 30 and 180 days, all-cause mortality. No variable had a c-index>0.70, and few had values>0.60; c-indices were lower for composite outcomes than for mortality. Blood urea was generally the strongest single predictor. Eighteen variables contributed independent prognostic information, but a reduced model using only 8 items (age, previous heart failure hospitalization, peripheral edema, systolic blood pressure, serum sodium, urea, creatinine, and albumin) performed similarly. For prediction of all-cause mortality at 180 days, the model c-index using all variables was 0.72 and for the simplified model, also 0.72. A few simple clinical variables measured on admission in patients with acute heart failure predict a variety of adverse outcomes with accuracy similar to more complex models. However, predictive models were of only moderate accuracy, especially for outcomes that included nonfatal events. Better methods of risk stratification are required.

    Multiple studies claim that public place smoking bans are associated with reductions in smoking-related hospitalization rates. No national study using complete hospitalization counts by area that accounts for contemporaneous controls including state cigarette taxes has been conducted. We examine the association between county-level smoking-related hospitalization rates and comprehensive smoking bans in 28 states from 2001 to 2008. Differences-in-differences analysis measures changes in hospitalization rates before versus after introducing bans in bars, restaurants, and workplaces, controlling for cigarette taxes, adjusting for local health and provider characteristics. Smoking bans were not associated with acute myocardial infarction or heart failure hospitalizations, but lowered pneumonia hospitalization rates for persons ages 60 to 74 years. Higher cigarette taxes were associated with lower heart failure hospitalizations for all ages and fewer pneumonia hospitalizations for adults aged 60 to 74. Previous studies may have overestimated the relation between smoking bans and hospitalizations and underestimated the effects of cigarette taxes.

    Heart failure is one of the most urgent medical and socio-economic challenges of the 21(st) century. Up to three million people are affected in Germany; this means one in ten people over the age of 65  live with heart failure. The current demographic changes will accentuate the importance of this grave health problem. The care of patients with heart failure, as well as the associated research mandates a comprehensive, multidisciplinary approach. The Competence Network Heart Failure (CNHF) pursues this objective. CNHF is a research alliance with 11 sites in Germany and was funded by the Federal Ministry of Research (BMBF) from 2003 through 2014. Since January 2015, the network has been an associate cooperating partner of the German Centre for Cardiovascular Research (DZHK). During the 12-year funding period by the BMBF, scientists in the field of heart failure from 30 university hospitals, 5 research institutes, 7 heart centers, 17 cardiovascular clinics, over 200 general practitioners, 4 rehabilitation clinics, as well as numerous organizations and associations were involved in cooperative CNHF research. In the context of 22 projects, the CNHF covered basic, clinical, and health care research, and generated numerous groundbreaking insights into disease mechanisms, as well as diagnosis and treatment of heart failure, which are documented in more than 350 publications. With its central study database and bank of biomaterials, the network has set up a Europe-wide unique research resource, which can be used in the future for national and international cooperations with the DZHK and other partners. Furthermore, the CNHF strongly promotes nation- and Europe-wide public relations and heart failure awareness activities.

    The relationship among anemia, renal dysfunction, left ventricular ejection fraction, and outcomes of patients hospitalized for acute decompensated heart failure is unclear. The aim of this study was to evaluate the association between cardiorenal anemia syndrome and postdischarge outcomes in patients hospitalized for heart failure with a preserved or reduced ejection fraction. Of 4842 patients enrolled in the Acute Decompensated Heart Failure Syndromes Registry between April 1, 2007 and December 31, 2011, 4393 patients were evaluated to investigate the association among anemia, renal dysfunction, preserved or reduced ejection fraction, and the primary end point (mortality and readmission for heart failure since discharge). The patients were divided into four groups on the basis of eGFR and hemoglobin at discharge. The median follow-up period after discharge was 432 (range=253-659) days. The primary end point was reached in 37.6% and 34.8% of the preserved and reduced ejection fraction groups, respectively. After adjustment for multiple comorbidities, there was no significant association of either renal dysfunction or anemia alone with the primary end point in patients with preserved ejection fraction, but the combination of renal dysfunction and anemia was associated with a significantly higher risk than that without either condition (hazard ratio, 1.54; 95% confidence interval, 1.12 to 2.12; Prenal dysfunction alone (hazard ratio, 1.65; 95% confidence interval, 1.21 to 2.25; P=0.002) and also, renal dysfunction plus anemia relative to the risk without either condition (hazard ratio, 2.19; 95% confidence interval, 1.62 to 2.96; Prenal dysfunction combined with anemia is associated with an increased risk of adverse postdischarge outcomes in patients with preserved ejection fraction, whereas renal dysfunction is an independent predictor of the risk of adverse outcomes in patients with reduced ejection fraction, regardless of anemia.

    Plasma B-type natriuretic peptide (BNP) levels may vary widely among patients with similar stages of heart failure, in whom obesity might be the only factor reducing plasma BNP levels. We investigated the effect of obesity and body mass index (BMI) on plasma BNP levels using serial measurements before and after treatment (pre- and post-BNP and pre- and post-BMI) in patients with acute heart failure. Multiple regression analysis and covariance structure analysis were performed to study the interactions between clinical factors in 372 patients. The pre-BMI was shown as a combination index of obesity and fluid accumulation, whereas the post-BMI was a conventional index of obesity. There was a significant inverse correlation between BMI and BNP in each condition before and after treatment for heart failure. The direct significant associations of the log pre-BNP with the log post-BNP (β: 0.387), the post-BMI (β: -0.043), and the pre-BMI (β: 0.030) were analyzed by using structural equation modeling. The post-BMI was inversely correlated, but importantly, the pre-BMI was positively correlated, with the log pre-BNP, because the pre-BMI probably entailed an element of fluid accumulation. There were few patients with extremely high levels of pre-BNP among those with high post-BMI, due to suppressed secretion of BNP. The low plasma BNP levels in true obesity patients with acute heart failure are of concern, because plasma BNP cannot increase in such patients. Copyright © 2016 The Authors.

    2008-03-01

    There are a number of factors related to heart failure pathophysiology and treatment that influence nutrient requirements for patients. These include catabolism, inflammation, oxidative stress, diuretic use, and presence of comorbidities. On the other hand, there is evidence that specific nutrients can alter heart failure pathophysiology. This article reviews the current evidence for nutritional recommendations regarding sodium and fluid restriction, macro- and micronutrient intake, and dietary changes required by the presence of common comorbidities.

    Acute heart failure (AHF) is characterized by inadequate cardiac output (CO), congestive symptoms, poor peripheral perfusion and end-organ dysfunction. Treatment often includes a combination of diuretics, oxygen, positive pressure ventilation, inotropes and vasodilators or vasopressors. Lactate is a marker of illness severity but is also an important metabolic substrate for the myocardium at rest and during stress. We tested the effects of half-molar sodium lactate infusion on cardiac performance in AHF. We conducted a prospective, randomised, controlled, open-label, pilot clinical trial in 40 patients fulfilling two of the following three criteria for AHF: (1) left ventricular ejection fraction Hartmann's solution without continuous infusion. The primary outcome was CO assessed by transthoracic echocardiography 24 hours after randomisation. Secondary outcomes included a measure of right ventricular systolic function (tricuspid annular plane systolic excursion (TAPSE)), acid-base balance, electrolyte and organ function parameters, along with length of stay and mortality. The infusion of half-molar sodium lactate increased (mean ± SD) CO from 4.05 ± 1.37 L/min to 5.49 ± 1.9 L/min (P < 0.01) and TAPSE from 14.7 ± 5.5 mm to 18.3 ± 7 mm (P = 0.02). Plasma sodium and pH increased (136 ± 4 to 146 ± 6 and 7.40 ± 0.06 to 7.53 ± 0.03, respectively; both P < 0.01), but potassium, chloride and phosphate levels decreased. There were no significant differences in the need for vasoactive therapy, respiratory support, renal or liver function tests, duration of ICU and hospital stay or 28- and 90-day mortality. Infusion of half-molar sodium lactate improved cardiac performance and led to metabolic alkalosis in AHF patients without any detrimental effects on organ function. Clinicaltrials.gov NCT01981655.

    2017-12-14

    Background -The concept of natriuretic peptide guidance has been extensively studied in chronic heart failure (HF) patients, with only limited success. The effect of NT-proBNP-guided therapy in acute decompensated HF (ADHF) patients using a relative NT-proBNP target has not been investigated. The aim of this study was to assess whether NT-proBNP-guided therapy of ADHF patients using a relative NT-proBNP target would lead to improved outcome compared with conventional therapy. Methods -We conducted a prospective randomized, controlled trial to study the impact of in-hospital guidance for ADHF treatment by a predefined NT-proBNP target (>30% reduction from admission to discharge) versus conventional treatment. ADHF patients with NT-proBNP levels of > 1700 ng/L were eligible. After achieving clinical stability, 405 patients were randomized to either NT-proBNP-guided or conventional treatment (1:1). The primary endpoint was dual, i.e. a composite of all-cause mortality and HF readmissions in 180 days, and the number of days alive out of the hospital in 180 days. Secondary endpoints were all-cause mortality within 180 days, HF readmissions within 180 days, and a composite of all-cause mortality and HF readmissions within 90 days. Results -Significantly more patients in the NT-proBNP-guided therapy group were discharged with an NT-proBNP reduction of >30% (80% versus 64%, P=0.001). Nonetheless, NT-proBNP-guided therapy did not significantly improve the combined event rate for all-cause mortality and HF readmissions (HR for NT-proBNP-guided therapy, 0.96; 95% CI, 0.72 to 1.37; P=0.99), or the median number of days alive outside of the hospital (178 vs. 179 days for NT-proBNP vs. conventional patients, P=0.39). Guided therapy also did not significantly improve any of the secondary endpoints. Conclusions -The PRIMA II demonstrates that that guidance of HF therapy to reach an NT-proBNP reduction of >30% after clinical stabilization did not improve 6-months outcome. Clinical

    Full Text Available Heart failure is appropriately described as an epidemic, with 1–2% of health care expenditure being directed at its management. In England, the National Institute for Health and Care Excellence (NICE has issued guidance on the best practice for the diagnosis and treatment of acute and chronic heart failure. Echocardiography is key to the diagnosis of the underlying cardiac abnormalities, and access to this (with our without biochemical testing using natriuretic peptides is key to high-quality and speedy diagnosis. New models of care aim to speed up access to echocardiography, but a shortage of technically trained staff remains a limiting factor in improving standards of care. The NHS audits the quality of care and outcome for patients admitted to hospital with heart failure, and this continues to show wide variation in practice, particularly, where patients are not reviewed by the local heart failure multidisciplinary team. Recently, the All Party Parliamentary Group on Cardiac Disease issued 10 suggestions for improvement in care for patients with heart failure – access to echocardiography being one of the key suggestions. Time will tell as to whether this support from law makers will assist in the implementation of NICE-recommended standards of care consistently across the country.

    Acute heart failure (HF) is a frequently encountered cardiac condition. Its prevalence increases exponentially with age. In spite of this, elderly patients are underrepresented in clinical trials and the implementation of guideline-based medical therapy (GBMT) in them is not well established. We investigated the current use of GBMT and its effects on mortality and HF rehospitalization among elderly patients with acute HF with reduced ejection fraction (HFrEF) using data obtained from a contemporary multi-center registry. We analyzed data from 1,441 consecutive acute HF patients registered in the West Tokyo Heart Failure (WET-HF) registry (mean age 73.2 ± 13.6 years). Reduced ejection fraction (elderly group). The prescription rate of GBMT (use of renin-angiotensin system inhibitors and β-blockers at discharge) was significantly lower in the elderly than in the younger (aged elderly group (HR 1.41, 95% CI 0.68-2.92; and HR 1.54, 95% CI 0.76-3.13, respectively) CONCLUSIONS: GBMT implementation in elderly patients with HFrEF was found to be suboptimal. However, the underuse of GBMT did not appear to be responsible for poorer outcomes in elderly HFrEF patients. Further research is required to establish an ideal therapeutic approach for this population. URL: http://www.umin.ac.jp/icdr/index-j.html. Unique identifier: UMIN000001171.

    The purpose of this study was to report prevalence, clinical characteristics, precipitating factors, management and outcome of patients with coronary artery disease (CAD) among patients hospitalized with heart failure (HF) in seven Middle Eastern countries and compare them to non-CAD patients. Data were derived from Gulf CARE (Gulf aCute heArt failuRe rEgistry), a prospective multicenter study of 5005 consecutive patients hospitalized with acute HF during February-November 2012 in 7 Middle Eastern countries. The prevalence of CAD among Acute Heart Failure (AHF) patients was 60.2% and varied significantly among the 7 countries (Qatar 65.7%, UAE 66.6%, Kuwait 68.0%, Oman 65.9%, Saudi Arabia 62.5%, Bahrain 52.7% and Yemen 49.1%) with lower values in the lower income countries. CAD patients were older and more likely to have diabetes, hypertension, dyslipidemia and chronic kidney disease. Moreover, CAD patients were more likely to have history of cerebrovascular and peripheral vascular disease when compared to non-CAD patients. In-hospital mortality rates were comparable although CAD patients had more frequent re-hospitalization and worse long-term outcome. However, CAD was not an independent predictor of poor outcome. The prevalence of CAD amongst patients with HF in the Middle East is variable and may be related to healthcare sources. Regional and national studies are needed for assessing further the impact of various etiologies of HF and for developing appropriate strategies to combat this global concern.

    To determine if newer criteria for diagnosing and staging acute kidney injury (AKI) during heart failure (HF) admission are more predictive of clinical outcomes at 30 days and 1 year than the traditional worsening renal function (WRF) definition. We analyzed prospectively collected clinical data on 637 HF admissions with 30-day and 1-year follow-up. The incidence, stages, and outcomes of AKI were determined using the following four definitions: KDIGO, RIFLE, AKIN, and WRF (serum creatinine rise ≥0.3 mg/dl). Receiver operating curves were used to compare the predictive ability of each AKI definition for the occurrence of adverse outcomes (death, rehospitalization, dialysis). AKI by any definition occurred in 38.3% (244/637) of cases and was associated with an increased incidence of 30-day (32.3 vs. 6.9%, χ(2) = 70.1; p < 0.001) and 1-year adverse outcomes (67.5 vs. 31.0%, χ(2) = 81.4; p < 0.001). Most importantly, there was a stepwise increase in primary outcome with increasing stages of AKI severity using RIFLE, KDIGO, or AKIN (p < 0.001). In direct comparison, there were only small differences in predictive abilities between RIFLE and KDIGO and WRF concerning clinical outcomes at 30 days (AUC 0.76 and 0.74 vs. 0.72, χ(2) = 5.6; p = 0.02) as well as for KDIGO and WRF at 1 year (AUC 0.67 vs. 0.65, χ(2) = 4.8; p = 0.03). During admission for HF, the benefits of using newer AKI classification systems (RIFLE, AKIN, KDIGO) lie with the ability to identify those patients with more severe degrees of AKI who will go on to experience adverse events at 30 days and 1 year. The differences in terms of predictive abilities were only marginal.

    Heart failure is associated with generalized insulin resistance. Moreover, insulin resistant states such as type 2 diabetes and obesity increases the risk of heart failure even after adjusting for traditional risk factors. Insulin resistance or type 2 diabetes alters the systemic and neurohumoral milieu leading to changes in metabolism and signaling pathways in the heart that may contribute to myocardial dysfunction. In addition, changes in insulin signaling within cardiomyocytes develop in the failing heart. The changes range from activation of proximal insulin signaling pathways that may contribute to adverse left ventricular remodeling and mitochondrial dysfunction to repression of distal elements of insulin signaling pathways such as forkhead (FOXO) transcriptional signaling or glucose transport which may also impair cardiac metabolism, structure and function. This article will review the complexities of insulin signaling within the myocardium and ways in which these pathways are altered in heart failure or in conditions associated with generalized insulin resistance. The implications of these changes for therapeutic approaches to treating or preventing heart failure will be discussed. PMID:27034277

    Full Text Available BACKGROUND Chronic Heart Failure (CHF represents worldwide a clinical condition with increasing prevalence, high social, economical and epidemiological impact. Even if new pharmacological and non-pharmacological approachs have been recently used, mortality remains high in general population and quality of life is poor in these patients. DISCUSSION The association between CHF and sleep disorders is frequent but still undervalued: sleep apnoeas in CHF produce negative effects on cardiovascular system and an aggravation of prognosis. CPAP (Continuous Positive Airway Pressure is commonly used to treat sleep apnoeas in patients without cardiac involvement and it is also used in first line treatment of acute cardiogenic pulmonary oedema thanks to its hemodynamic and ventilatory effects. The addition of nightly CPAP to standard aggressive medical therapy in patients with CHF and sleep apnoeas reduces the number of apnoeas, reduces the blood pressure, and the respiratory and cardiac rate, reduces the activation of sympathetic nervous system, the left ventricular volume and the hospitalization rate; besides CPAP increases the left ventricular ejection fraction, amd the oxygenation, it improves quality of life, tolerance to exercise and seems to reduce mortality in patients with a higher apnoeas suppression. CONCLUSIONS These implications suggest to investigate sleep apnoeas in patients with CHF in order to consider a possible treatment with CPAP. Further studies need to be developed to confirm the use of CPAP in patients with CHF without sleep disorders.

    Acute decompensated heart failure (ADHF) is associated with significant morbidity and mortality but the relationship between LVEF and outcomes is unclear. We explored the association between LVEF and 30 and 180 day mortality in 7007 ADHF patients enrolled in the Acute Studies of Nesiritide in Decompensated Heart Failure (ASCEND-HF) trial. We explored the association between LVEF and 30 and 180 day mortality in 7007 ADHF patients enrolled in the Acute Studies of Nesiritide in Decompensated Heart Failure (ASCEND-HF) trial. LVEF was analysed both as a continuous variable and according to three categories: IntEF)], and > 50% [preserved ejection fraction (PresEF)]. Of the patients in the trial, 4474 (78.7%) had LowEF, 674 (11.9%) had IntEF, and 539 (9.5%) had PresEF. The unadjusted 30 and 180 day mortality was similar for LowEF (3.7%, 12.3%), IntEF (3.4%, 13.1%), and PresEF (4.3%, 14.1%), respectively (P > 0.05). After multivariable adjustment, the hazard ratio (HR) for 180 day mortality remained similar for the LowEF [HR 0.96, 95% confidence interval (CI) 0.75-1.24; P = 0.77] and IntEF (0.91, 95% CI 0.66-1.3; P = 0.58) compared to PresEF patients. By contrast, when LVEF was evaluated as a continuous measure, it exhibited a U-shaped pattern with mortality. After matching for age and sex, the mortality risk attributed to LVEF was attenuated, as the LVEF increased as a continuous variable over 35%. However, in patients with EF < 35%, the mortality risk continue to increase as the LVEF declined. Among patients with ADHF, the unadjusted mortality rates are similar across LVEF strata. However, after accounting for key patient variables, the mortality risk increases as EF falls below 35%. These data will be useful in planning future studies of ADHF. www.clinicaltrials.gov identifier: NCT00475852. © 2013 The Authors.

    The purpose of this study was to investigate the predictive values of baseline and changes in cystatin C (CysC) and its derived equations for short-term adverse outcomes and the effect of nesiritide therapy on CysC in acute decompensated heart failure (ADHF). Newer renal biomarkers or their derived estimates of renal function have demonstrated long-term prognostic value in chronic heart failure. CysC levels were measured in sequential plasma samples from 811 subjects with ADHF who were enrolled in the ASCEND-HF (Acute Study of Clinical Effectiveness of Nesiritide in Decompensated Heart Failure) biomarker sub-study (randomized to nesiritide therapy vs. placebo), and followed for all-cause death (180 days) and recurrent hospital stay (30 days). Median CysC levels were 1.49 (interquartile range [IQR]: 1.20 to 1.96) mg/l at baseline, 1.56 (IQR: 1.28 to 2.13) mg/l at 48 to 72 h, and 1.58 (IQR: 1.24 to 2.11) mg/l at 30 days. Higher baseline (but not follow-up) CysC levels were associated with increased risk of 30-day adverse events and less improvement in dyspnea after 24 h as well as 180-day mortality, although not incremental to blood urea nitrogen. Worsening renal function (defined as a 0.3 mg/l increase in CysC) occurred in 161 of 701 (23%) patients, but it was not predictive of adverse events. Changes in CysC levels were similar between the nesiritide and placebo groups. Our findings confirmed the prognostic value of baseline CysC levels in the setting of ADHF. However, worsening renal function based on CysC rise was not predictive of adverse events. Nesiritide did not worsen renal function compared with placebo.

    Emergency departments are a major entry point for the initial management of acute heart failure (AHF) patients throughout the world. The initial diagnosis, management and disposition - the decision to admit or discharge - of AHF patients in the emergency department has significant downstream implications. Misdiagnosis, under or overtreatment, or inappropriate admission may place patients at increased risk for adverse events, and add costs to the healthcare system. Despite the critical importance of initial management, data are sparse regarding the impact of early AHF treatment delivered in the emergency department compared to inpatient or chronic heart failure management. Unfortunately, outcomes remain poor, with nearly a third of patients dying or re-hospitalised within 3 months post-discharge. In the absence of robust research evidence, consensus is an important source of guidance for AHF care. Thus, we convened an international group of practising emergency physicians, cardiologists and advanced practice nurses with the following goals to improve outcomes for AHF patients who present to the emergency department or other acute care setting through: (a) a better understanding of the pathophysiology, presentation and management of the initial phase of AHF care; (b) improving initial management by addressing knowledge gaps between best practices and current practice through education and research; and (c) to establish a framework for future emergency department-based international education and research.

    Full Text Available An experiment on 106 non-inbred male albino rats undergone 4-minute clinical death from acute blood loss has revealed that the first three days after resuscitation are marked by a concomitance of vascular disorders and cardiomyocytic dystrophic changes, the leading role being played by sludge, stasis, thrombosis, increased vascular permeability, perivascular edema, and hemorrhages. Cardiomyocytic destruction (various contractures, block-like myofibrillolysis, myocytoly-sis is a structural basis of postresuscitative heart failure. Three days later the heart displayed concomitant processes of recovery and damage. Three types of cardiac morphological changes have been identified in relation to the ratio of these processes.

    n 1987 the results of the Consensus study were published, and showed that enalapril, an angiotensin convertor enzyme inhibitor (ACEI), was able to modify the clinical course of the heart failure syndrome thereby reducing mortality. Other ACEI later demonstrated the same effect on the different degrees of symptomatic heart failure, left ventricular dysfunction, myocardial infarction and more recently in diabetic patients. In 1996 studies on the betablockers carvedilol, bisoprolol and metoprolol showed their efficacy in reducing deaths due to progressive heart impairment and sudden death in chronic heart failure. The RALES study showed that small doses of spironolactone also improved the prognosis on this disease. Digital improves the quality of life but not the survival rate. Only amiodarone (among the antiarrhythmics) reduces sudden death. Other drugs and groups of drugs can not be considered for chronic outpatient treatment of heart failure. Multicenter trials make it possible to obtain scientific evidence for establishing rational treatments. Many groups of patients such as women, elderly people and the more severe cases of the disease are often not included in these trials. Occasionally, multicenter trials are badly designed (CIBIS and MCD), which in the case of betablockers, led to a substantial delay in their administration. Other times, as in the ELITE study, the results were badly interpreted. The knowledge obtained from these studies is slow in reaching patients, with few patients taking betablockers. It is known that most patients do not take the doses found to be effective in multicenter trials.

    Aspirin and statins are established therapies for acute myocardial infarction (MI), but their benefits in patients with chronic heart failure (HF) remain elusive. We investigated the impact of aspirin and statins on long-term survival in patients hospitalized with acute MI complicated by HF. Of 4251 patients in the Evaluation of Methods and Management of Acute Coronary Events (EMMACE)-1 and -2 observational studies, 1706 patients had HF. A propensity score-matching method estimated the average treatment effects (ATEs) of aspirin and statins on survival over 90 months. ATEs were calculated as relative risk differences in all-cause mortality comparing patients receiving aspirin and statins with controls, respectively. Moreover, combined aspirin and statins vs. none (ATE I), aspirin or statins vs. none (ATE II), and aspirin and statins vs. aspirin or statins (ATE III) were assessed. The median survival times of the ATE I, ATE II and ATE III were 25, 50, and 85 months, respectively. Regarding aspirin, the ATE was significantly improved at 6, 12, and 90 months [ATE 6 months: 10%, 95% confidence interval (CI) 3-18%], where the ATE of statins favoured survival at 1-24 months (ATE 1 month: 5%, 95% CI 0.3-10%). Mortality was lower at 1, 6, and 24 months in those who received aspirin and statins (ATE I). When the combination was compared with either treatment alone, an effect persisted between 6 and 90 months (ATE III). In patients with acute MI complicated by HF, prescription of aspirin and statins either alone or together was associated with better long-term survival. © 2013 The Authors.

    In 2003, chronic obstructive pulmonary disease (COPD) accounted for 46% of the burden of chronic respiratory disease in the Australian community. In the 65-74-year-old age group, COPD was the sixth leading cause of disability for men and the seventh for women. To measure the influence of disease severity, COPD phenotype and comorbidities on acute health service utilization and direct acute care costs in patients admitted with COPD. Prospective cohort study of 80 patients admitted to the Royal Melbourne Hospital in 2001-2002 for an exacerbation of COPD. Patients were followed for 12 months and data were collected on acute care utilization. Direct hospital costs were derived using Transition II, an activity-based costing system. Individual patient costs were then modelled to ascertain which patient factors influenced total direct hospital costs. Direct costs were calculated for 225 episodes of care, the median cost per admission was AU$3124 (interquartile range $1393 to $5045). The median direct cost of acute care management per patient per year was AU$7273 (interquartile range $3957 to $14 448). In a multivariate analysis using linear regression modelling, factors predictive of higher annual costs were increasing age (P= 0.041), use of domiciliary oxygen (P= 0.008) and the presence of chronic heart failure (P= 0.006). This model has identified a number of patient factors that predict higher acute care costs and awareness of these can be used for service planning to meet the needs of patients admitted with COPD.

    Although 80% of patients with heart failure seen in the emergency department (ED) are admitted, less is known about short-term outcomes and demand for services among discharged patients. We examined adult members of a large integrated delivery system who visited an ED for acute heart failure and were discharged from January 1, 2013, through September 30, 2014. The primary outcome was a composite of repeat ED visit, hospital admission, or death within 7 days of discharge. We identified multivariable baseline patient-, provider-, and facility-level factors associated with adverse outcomes within 7 days of ED discharge using logistic regression. Among 7614 patients, mean age was 77.2 years, 51.9% were women, and 28.4% were people of color. Within 7 days of discharge, 75% had outpatient follow-up (clinic, telephone, or e-mail), 7.1% had an ED revisit, 4.7% were hospitalized, and 1.2% died. Patients who met the primary outcome were more likely to be older, smokers, have a history of hemorrhagic stroke, hypothyroidism, and dementia, and less likely to be treated in a facility with an observation unit. In multivariable analysis, higher comorbidity scores and history of smoking were associated with a higher odds of the primary outcome, whereas treatment in a facility with an observation unit and presence of outpatient follow-up within 7 days were associated with a lower odds. We identified selected hospital and patient characteristics associated with short-term adverse outcomes. Further understanding of these factors may optimize safe outpatient management in ED-treated patients with heart failure. © 2017 American Heart Association, Inc.

    Physicians responsible for the care of patients with heart failure due to left ventricular systolic dysfunction have access to a broad range of evidence-based treatments that prolong life and reduce symptoms. In spite of the significant progress made over the last four decades, there is an ongoing need for novel therapies to treat a condition that is associated with stubbornly high morbidity and mortality. In this article, we discuss the findings of SERVE-HF, a randomised controlled trial of adaptive servo-ventilation in patients with left ventricular systolic dysfunction, as well as EMPA-REG, a study of the effects of a novel diabetic agent that may be of greater interest to heart failure specialists than diabetologists. We also examine further analyses of the groundbreaking PARADIGM-HF trial, which attempt to answer some of the unresolved questions from the original study of the first combined angiotensin-receptor blocker and neprilysin inhibitor, sacubitril valsartan. The recently published National Institute for Health and Care Excellence guidelines for the management of acute heart failure and plans to introduce best practice tariffs bring into focus the need for well-organised, multidisciplinary care. We discuss the challenges involved in developing and delivering a specialist service that meets the needs of a growing population of patients living with heart failure. © Royal College of Physicians 2016.

    Renal dysfunction is common during episodes of acute decompensated heart failure, and historical data indicate that the mean creatinine level at admission has risen in recent decades. Different mechanisms underlying this change over time have been proposed, such as demographic changes, hemodynamic and neurohumoral derangements and medical interventions. In this setting, various strategies have been proposed for the prevention of renal dysfunction with heterogeneous results. In the present article, we review and discuss the main aspects of renal dysfunction prevention according to the different stages of heart failure. PMID:23644863

    Aims Explore the association between clinical findings and prognosis in patients with acute decompensated heart failure (ADHF) and analyze the influence of etiology on clinical presentation and prognosis. Methods and results Prospective cohort of 500 patients admitted with ADHF from Aug/2013-Feb/2016; patients were predominantly male (61.8%), median age was 58 (IQ25-75% 47–66 years); etiology was dilated cardiomyopathy in 141 (28.2%), ischemic heart disease in 137 (27.4%), and Chagas heart disease in 113 (22.6%). Patients who died (154 [30.8%]) or underwent heart transplantation (53[10.6%]) were younger (56 years [IQ25-75% 45–64 vs 60 years, IQ25-75% 49–67], P = 0.032), more frequently admitted for cardiogenic shock (20.3% vs 6.8%, Pheart transplant was higher among patients with Chagas (50.5%). Conclusions A physical exam may identify patients at higher risk in a contemporaneous population. Our findings support specific therapies targeted at Chagas patients in the setting of ADHF.

    In acute decompensated heart failure (ADHF) with preserved ejection fraction (HFpEF) there are no surrogate endpoints for early phase trials. The aim of the current study was to evaluate whether a reduction in natriuretic peptides (NP) between acute hospital presentation to stable follow-up is associated with improved mortality and morbidity. Patients presenting acutely to the hospital for ADHF with HFpEF enrolled in the Karolinska Rennes (KaRen) study and reporting N-terminal pro-B-type NP or B-type NP assessment at baseline hospital presentation and at 4-8weeks follow-up were prospectively studied. Logistic regression analyses were performed to detect the predictors of baseline and changes in NPs. Cox regression models were performed to assess the impact of NP reductions on mortality and the composite of mortality and HF hospitalization. Of 361 patients (median follow-up 585days), 267 (74%) reported an improvement in NPs, while 94 (26%) reported worsening. At baseline, the independent predictors of lower NPs were higher glomerular filtration rate (Odds Ratio [OR] per unit: 1.013; 95% Confidence Interval [CI]: 1.005-1.021) and younger age (OR per year: 0.972; CI: 0.947-0.998). Improvement in NPs at follow-up was predicted by higher heart rate at baseline (OR per bpm: 1.014; CI: 1.003-1.025). After adjustments, the hazard ratio for all-cause death was 0.730 (CI: 0.456-1.169) and for the composite outcome 0.814 (CI: 0.582-1.139) for patients who improved vs. worsened in NP levels. In patients presenting acutely to the hospital with HFPEF, an improvement in NP levels did not independently and significantly predict improved mortality and/or morbidity. NPs as surrogate endpoints in acute HFpEF require further study. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    Aldosterone prevents the uptake of norepinephrine in the myocardium. Atrial natriuretic peptide (ANP), a circulating hormone of cardiac origin, inhibits aldosterone synthase gene expression in cultured cardiocytes. We evaluated the effects of intravenous ANP on cardiac sympathetic nerve activity (CSNA) and aldosterone suppression in patients with acute decompensated heart failure (ADHF). We studied 182 patients with moderate nonischemic ADHF requiring hospitalization and treated with standard therapy containing intravenous ANP and 10 age-matched normal control subjects. ANP was continuously infused for >96 h. In all subjects, delayed total defect score (TDS), heart to mediastinum ratio, and washout rate were determined by {sup 123}I-metaiodobenzylguanidine (MIBG) scintigraphy. Left ventricular (LV) end-diastolic volume, end-systolic volume, and ejection fraction were determined by echocardiography. All patients with acute heart failure (AHF) were examined once within 3 days and then 4 weeks after admission, while the control subjects were examined only once (when their hemodynamics were normal). Moreover, for 62 AHF patients, plasma aldosterone concentrations were measured at admission and 1 h before stopping ANP infusion. {sup 123}I-MIBG scintigraphic and echocardiographic parameters in normal subjects were more favorable than those in patients with AHF (all p < 0.001). After treatment, all these parameters improved significantly in AHF patients (all p < 0.001). We also found significant correlation between percent changes of TDS and aldosterone concentrations (r = 0.539, p < 0.001) in 62 AHF patients. The CSNA and LV performance were all improved in AHF patients. Furthermore, norepinephrine uptake of myocardium may be ameliorated by suppressing aldosterone production after standard treatment containing intravenous ANP. (orig.)

    The risk stratification for prognosis in heart failure is very important for optimal disease management and decision making. The aim of this study was to establish a simple discharge 1-year mortality prediction model by integrating data obtained from demographic characteristics, clinical evaluation, laboratory biomarkers and echocardiographic evaluation of hospitalised heart failure with reduced ejection fraction (HFrEF) patients with acute decompensation. A risk score model was developed based on β-coefficient number of variables in a multivariable logistic regression model which was created with the use of data on clinical, laboratory, imaging and therapeutic findings of 670 patients (65.4% males, 65 ± 11 years) who was hospitalised with acute decompensated HFrEF. The mean left ventricular ejection fraction (LVEF) was 26 ± 9%. Independent predictors of mortality were: age ≥75 years, sodium <130 mEq/L, hepatomegaly at admission, unable to use beta-blocker at discharge and LVEF ≤20%. The 1-year mortality rate was 7.8% in the study population. The existence of each predictor was scored as 1 point and the discharge risk score identified patients into low (0-1 points), intermediate (2-3 points) and high (4-5 points) risk individuals with 3, 15.6 and 44.4% 1-year mortality rates, respectively. The model performance evaluated by concordance index was 0.74. This simple discharge risk score model for hospitalised acute decompensated HFrEF patients using easily determined demographic characteristics, clinical signs, echocardiographic and laboratory data is a valuable and an easy risk assessment tool to use at point-of-care.

    Congestive hepatopathy (CH) and acute liver failure (ALF) are common among biventricular heart failure patients. We sought to evaluate the impact of total artificial heart (TAH) therapy on hepatic function and associated clinical outcomes. A total of 31 patients received a Syncardia Total Artificial Heart. Preoperatively 17 patients exhibited normal liver function or mild hepatic derangements that were clinically insignificant and did not qualify as acute or chronic liver failure, 5 patients exhibited ALF and 9 various hepatic derangements owing to CH. Liver associated mortality and postoperative course of liver values were prospectively documented and retrospectively analyzed. Liver associated mortality in normal liver function, ALF and CH cases was 0%, 20% (P=0.03) and 44.4% (P=0.0008) respectively. 1/17 (5.8%) patients with a normal liver function developed an ALF, 4/5 (80%) patients with an ALF experienced a markedly improvement of hepatic function and 6/9 (66.6%) patients with CH a significant deterioration. TAH therapy results in recovery of hepatic function in ALF cases. Patients with CH prior to surgery form a high risk group with increased liver associated mortality.

    Higher body mass index (BMI) is associated with lower circulating levels of N-terminal-pro-b-type natriuretic peptide (NT-proBNP). The Interaction between BMI and NT-proBNP with respect to clinical outcomes is not well characterized in patients with acute heart failure. A total of 686 patients from the biomarker substudy of the ASCEND-HF (Acute Study of Clinical Effectiveness of Nesiritide in Decompensated HF ) clinical trial with documented NT-proBNP levels at baseline were included in the present analysis.

  19. High affinity complexes of pannexin channels and L-type calcium channel splice-variants in human lung: Possible role in clevidipine-induced dyspnea relief in acute heart failure

    Research in Context: Clevidipine lowers blood pressure by inhibiting calcium channels in vascular smooth muscle. In patients with acute heart failure, clevidipine was shown to relieve breathing problems. This was only partially related to the blood pressure lowering actions of clevidipine and not conferred by another calcium channel inhibitor. We here found calcium channel variants in human lung that are more selectively inhibited by clevidipine, especially when associated with pannexin channels. This study gives a possible mechanism for clevidipine's relief of breathing problems and supports future clinical trials testing the role of clevidipine in the treatment of acute heart failure.

    Heart failure has the highest rates of adult hospitalisations, the highest mortality rates and significant costs associated with its care. The cost of heart failure is expected continue to grow on a global scale, with $108 billion spent on heart failure in 2012. Mortality rates are high, with incident cases of heart failure resulting in 30% 1-year mortality, and in hospital mortality of acute heart failure, 28%. This article reviews the devices currently in use for the treatment of heart failure, as well as those that are under investigation. A review of the mechanism of action of devices, the literature supporting their application as therapy, and the cost effectiveness associated with their use are discussed. Conventional techniques discussed herein include the guideline-supported therapies of mechanical circulatory support (MCS) and cardiac resynchronisation therapy (CRT). Novel devices that are discussed include invasive physiological monitoring, neuromodulation, percutaneous ventricular assist devices (VADs) and cardiac contractility modulation (CCM). There has been advancement in mechanical circulatory support devices for the treatment of both acute and chronic heart failure. In addition to MCS, only CRT has resulted in reduced mortality. Due to the clinical and economic arguments, treatment of heart failure is said to be the biggest unmet need in cardiology today. The data reviewed herein support this statement.

    Patients hospitalized for heart failure (HF) are at high risk for 30-day readmission. This study sought to examine the timings and causes of readmission within 30 days of an HF hospitalization. Timing and cause of readmission in the ASCEND-HF (Acute Study of Clinical Effectiveness of Nesiritide and Decompensated Heart Failure) trial were assessed. Early and late readmissions were defined as admissions occurring within 0-7 days and 8-30 days post-discharge, respectively. Patients who died in hospital or remained hospitalized at day 30 post-randomization were excluded. Patients were compared by timing and cause of readmission. Logistic and Cox proportional hazards regression analyses were used to identify independent risk factors for early vs. late readmission and associations with 180-day outcomes. Of the 6584 patients (92%) in the ASCEND-HF population included in this analysis, 751 patients (11%) were readmitted within 30 days for any cause. Overall, 54% of readmissions were for non-HF causes. The median time to rehospitalization was 11 days (interquartile range: 6-18 days) and 33% of rehospitalizations occurred by day 7. Rehospitalization within 30 days was independently associated with increased risk for 180-day all-cause death [hazard ratio (HR) 2.38, 95% confidence interval (CI) 1.93-2.94; P HF trial population, a significant majority of 30-day readmissions were for non-HF causes and one-third of readmissions occurred in the first 7 days. Early and late readmissions within the 30-day timeframe were associated with similarly increased risk for death. Continued efforts to optimize multidisciplinary transitional care are warranted to improve rates of early readmission. © 2017 The Authors.

    In advanced congestive heart failure (CHF), intravenous (i.v.) inotropic agents, i.v. diuretics, ultrafiltration, and hemodialysis have been shown to not yield better clinical outcomes. In this scenario, the simultaneous administration of hypertonic saline solution (HSS) and furosemide may offer a more effective therapeutic option with a good safety profile. Therefore, a meta-analysis was performed to compare combined therapy, consisting of i.v. furosemide plus concomitant administration of HSS, with i.v. furosemide alone for acute decompensated heart failure (ADHF). The outcomes we chose were all-cause mortality, risk of re-hospitalization for ADHF, length of hospital stay, weight loss, and variation of serum creatinine. Based on five randomized controlled trials (RCTs) involving 1,032 patients treated with i.v. HSS plus furosemide vs. 1,032 patients treated with i.v. furosemide alone, a decrease in all-cause mortality in patients treated with HSS plus furosemide was proven [RR = 0.57; 95 % confidence interval (CI) = 0.44-0.74, p = 0.0003]. Likewise, combined therapy with HSS plus furosemide was shown to be associated with a reduced risk of ADHF-related re-hospitalization (RR = 0.51; 95 % CI = 0.35-0.75, p = 0.001). Besides, combined therapy with HSS plus furosemide was found to be associated with a reduced length of hospital stay (p = 0.0002), greater weight loss (p furosemide for diuretic-resistant CHF patients led to a better renal safety profile and improved clinical endpoints such as mortality and heart failure-related hospitalizations.

    Heart failure is a major chronic illness with no definitive cure. With improving healthcare and with an aging population in many countries, heart failure has become a common disease of the elderly. Pharmacological management of heart failure in the elderly remains a challenge. The syndrome of heart failure cannot be isolated from other comorbidities, which are very common in this population. The purpose of this review is to assist practicing clinicians to more effectively make decisions about management of heart failure in the elderly. In this review, we will try to integrate recent research studies, recent guidelines, and new treatment modalities, and discuss some controversies. In general, the elderly patient with heart failure should be treated according to current heart failure guidelines; however, untailored heart failure management may cause untoward effects in this age group and may worsen clinical outcome.

    Hradec, J

    2010-08-01

    Anaemia is a relatively frequent co-morbidity of chronic heart as well as chronic renal failure. In both conditions, it represents a strong and independent predictor of increased morbidity and mortality. Aetiology of this anaemia is multi-factorial. A number of various factors play a role in its development, e.g. inadequate erythropoietin production in the kidneys, bone marrow inhibition, iron deficiency as well as haemodilution associated with fluid retention. Treatment strategies aim at two directions. One is the stimulation of erythropoiesis with recombinant human erythropoietin or its analogues such as darbepoetin alpha. The other involves iron substitution, administered preferably intravenously for improved efficacy and tolerability. Clinical studies evaluating treatment of anaemia in chronic heart failure with erythropoiesis-stimulating agents conducted so far were ofa small scale, were not controlled with placebo and usually assessed proxy parameters. Their results suggested that effective treatment of anaemia in patients with chronic heart failure improves exertion tolerance, clinical status (NYHA class) as well as the quality of life and reduces the need for blood transfusions. Recently completed TREAT study was the first large morbidity and mortality study evaluating treatment of anaemia with an erythropoietin analogue compared to placebo. On a sample of more than 4000 patients with diabetes mellitus, chronic renal failure and significant anaemia, this study has shown that effective treatment of anaemia with darbepoetin alpha did not affect at all the incidence of cardiovascular and renal events; on the other hand, it had lead to a nearly two-fold increase in the incidence of cerebrovascular events. Some doubts about the safety of treatment with erythropoiesis-stimulating agents have occurred in the past based on the studies of anaemia treatment in patients with cancer and renal diseases. An answer to the question whether the treatment of anaemia

    Several blood tests are commonly used to assess nutritional status, including serum albumin levels (SAL) and lymphocyte counts (LC). The aim of this study is to investigate whether nutritional screening on admission can be used to determine risk levels for adverse clinical events in acute heart failure syndrome (AHFS) patients. In 432 consecutive AHFS patients, we measured SAL and LC and prospectively followed the patients for their combined clinical events (all-cause death and re-hospitalization for heart failure) for three years from admission. The classification and regression tree (CART) tool identified the cut-off criteria for SAL and LC to differentiate among patients with different risks of clinical events as 3.5g/dl and 963/mm(3), respectively. The CART tool classified 15.5% patients as high risk, 15.7% as intermediate risk, and 68.8% as low risk. The CART for nutritional status (CART-NS) values were strongly correlated with combined clinical events [hazard ratio of 2.13 (low vs high risk), 95% confidence interval of 1.42-3.16, pnutritional screening, even in emergency clinical settings, can determine risk levels for further adverse events in AHFS patients.

    The prognostic value of nutritional status is poorly understood and evidence-based nutritional assessment indices are required in acute heart failure (AHF). We investigated the prognostic value of malnutrition assessed by the Controlling Nutritional Status (CONUT) score (range 0-12, higher=worse, consisting of serum albumin, cholesterol and lymphocytes) in AHF patients. The CONUT score was measured on admission in 635 consecutive AHF patients. The primary outcome was all-cause death. Median CONUT score was 3 (interquartile range 2 to 5). During the median follow-up of 324days, CONUT score was independently associated with death (HR 1.26, 95% CI 1.11-1.42, Pnutritional markers in HF. Furthermore, addition of the CONUT score to an established risk prediction model from the Organized Program to Initiate Lifesaving Treatment in Hospitalized Patients with Heart Failure study significantly increased the C-statistic from 0.75 to 0.77 (P=0.02). The net reclassification improvement afforded by CONUT score was 21% for all-cause death, 27% for survival and 49% overall (Pnutritional indices. Moreover, addition of the score to the existing risk prediction model significantly increased the predictive ability for death, indicating beneficial clinical application of the CONUT score in AHF patients.

    Heart failure (HF) is a major public health problem affecting predominantly older adults. Nonadherence to diet remains a significant contributor to acute decompensated HF (ADHF). The sodium-restricted Dietary Approaches to Stop Hypertension (DASH/SRD) eating plan reduces cardiovascular dysfunction that can lead to ADHF and is consistent with current HF guidelines. We propose that an intervention that promotes adherence to the DASH/SRD by home-delivering meals will be safe and improve health-related quality of life (QOL) in older adults after hospitalization for ADHF. This is a 3-center, randomized, single-blind, controlled trial of 12-week duration designed to determine the safety and efficacy of home-delivered DASH/SRD-compliant meals in older adults after discharge from ADHF hospitalization. Sixty-six subjects will be randomized in a 1:1 stratified fashion by gender and left ventricular ejection fraction (<50% vs ≥50%). Study subjects will receive either preprepared, home-delivered DASH/SRD-compliant meals or usual dietary advice for 4weeks after hospital discharge. Investigators will be blinded to group assignment, food diaries, and urinary electrolyte measurements until study completion. The primary efficacy end point is the change in the Kansas City Cardiomyopathy Questionnaire summary scores for health-related QOL from study enrollment to 4weeks postdischarge. Safety evaluation will focus on hypotension, renal insufficiency, and hyperkalemia. Exploratory end points include echocardiography, noninvasive vascular testing, markers of oxidative stress, and salt taste sensitivity. This randomized controlled trial will test the efficacy, feasibility, and safety of 4weeks of DASH/SRD after ADHF hospitalization. By testing a novel dietary intervention supported by multiple levels of evidence including preliminary data in outpatients with stable HF, we will address a critical evidence gap in the care of older patients with ADHF. If effective and safe, this

    ALARM-HF was a retrospective, observational registry that included 4,953 patients admitted for acute heart failure (AHF) in six European countries, Turkey, Mexico and Australia. Data about respiratory disorders and related medications were available for 4,616 patients with AHF. Chronic obstructive pulmonary disease (COPD) patients (n = 1,143, 24.8%) were older and more frequently men (p 0.05), COPD patients more frequently presented with acutely decompensated heart failure (p cardiovascular profile was observed in the COPD group, including more atrial fibrillation/flutter, diabetes, hypertension, obesity, peripheral vascular disease (p < 0.001). Before admission, a higher percentage of COPD patients had experienced infections (25.0 vs. 14.0 %, p < 0.001), and were more likely to receive diuretics (p = 0.006), ACE inhibitors (p = 0.042), nitrates (p = 0.003), and digoxin (p = 0.034). With the exception of ACE inhibitors, those differences maintained at discharge, with concomitant increase in ARBs prescription (p = 0.01). Notably, β-blockers were less prescribed before admission (21.1 vs. 23.8%, p = 0.055) in COPD patients, and remained underutilized at discharge (p < 0.001). Correcting for baseline differences, all-cause in-hospital mortality did not differ between COPD and non-COPD groups (10.1 vs. 10.9%, p = 0.085). A large proportion of AHF patients presented with concomitant COPD, had different clinical characteristics/co-morbidities, and less frequently received evidence-based pharmacological therapy compared to non-COPD patients. However, the in-hospital mortality was not higher in COPD group.

    Our aim was to develop a model of acute right heart failure (ARHF) in the setting of pulmonary hypertension and to characterize acute right ventricular lesions that develop early after hemodynamic restoration. We used a described piglet model of chronic pulmonary hypertension (cPH) induced by pulmonary artery occlusions. We induced ARHF in animals with cPH (ARHF-cPH group, n = 9) by volume loading and iterative acute pulmonary embolism until hemodynamic compromise followed by dobutamine infusion for hemodynamic restoration before sacrifice for right ventricular tissue evaluation. The median duration of ARHF before sacrifice was 162 (135-189) minutes. Although ventriculoarterial coupling (measured with multibeat pressure-volume loops) and stroke volume decreased after iterative pulmonary embolism and improved with dobutamine, relative pulmonary to systemic pressure increased by 2-fold and remained similarly increased with dobutamine. Circulating high-sensitivity troponin I increased after hemodynamic restoration. We found an increase in right ventricular subendocardial and subepicardial focal ischemic lesions and in expression of autophagy-related protein LC3-II (Western blot) in the ARHF-cPH group compared with the cPH (n = 5) and control (n = 5) groups. We developed and phenotyped a novel large animal model of ARHF on cPH in which right ventricular ischemic lesions were observed early after hemodynamic restoration. Copyright © 2017 Elsevier Inc.

    Ischemia-modified albumin (IMA) is a sensitive biomarker of myocardial ischemia. However, data on IMA levels in acute heart failure (HF) are still lacking. In this study, we aimed to evaluate serum IMA levels in acute decompensated HF and the effects of dobutamine and levosimendan treatments on IMA levels. This was a prospective, multicenter study that included 70 patients hospitalized with acute decompensated HF and left ventricular ejection fraction HF therapy. Twenty-nine patients were treated with standard HF therapy, 18 received levosimendan, and 23 received dobutamine in addition to standard of care. A single serum specimen was also collected from 32 healthy individuals each. IMA concentrations were measured by the albumin cobalt binding colorimetric assay, and the results were given in absorbance units (AU). Independent and paired sample t-tests, Mann-Whitney U test, and Wilcoxon signed-rank test were used for the analysis. In patients with acute decompensated HF, the serum concentration of IMA was significantly higher than those of healthy subjects (0.894 ± 0.23 AU vs. 0.379 ± 0.08 AU, p HF therapy (0.894 ± 0.23 AU and 0.832 ± 0.18 AU, p = 0.013). Furthermore, the IMA levels were also found to significantly decrease with standard HF therapy (1.041 ± 0.28 vs. 0.884 ± 0.15 AU, p = 0.041), with levosimendan (0.771 ± 0.18 vs. 0.728 ± 0.18 AU, p = 0.046) and also with dobutamine (0.892 ± 0.18 vs. 0.820 ± 0.13 AU, p = 0.035). Patients with acute decompensated HF had elevated IMA levels, and appropriate HF therapy significantly reduced the serum IMA levels. Dobutamine or levosimendan did not increase the IMA levels, suggesting a lower potential in inducing myocardial ischemia when used in recommended doses.

    Nonalcoholic fatty liver disease (NAFLD) is an emerging risk factor for heart failure (HF). Although some progress has been made in improving survival among patients admitted for HF, the rates of hospital readmissions and the related costs continue to rise dramatically. We sought to examine whether NAFLD and its severity (diagnosed at hospital admission) was independently associated with a higher risk of 1-year all-cause and cardiac re-hospitalization in patients admitted for acute HF. We studied 212 elderly patients who were consecutively admitted with acute HF to the Hospital of Negrar (Verona) over a 1-year period. Diagnosis of NAFLD was based on ultrasonography, whereas the severity of advanced NAFLD fibrosis was based on the fibrosis (FIB)-4 score and other non-invasive fibrosis scores. Patients with acute myocardial infarction, severe valvular heart diseases, end-stage renal disease, cancer, known liver diseases or decompensated cirrhosis were excluded. Cox regression was used to estimate hazard ratios (HR) for the associations between NAFLD and the outcome(s) of interest. The cumulative rate of 1-year all-cause re-hospitalizations was 46.7% (n = 99, mainly due to cardiac causes). Patients with NAFLD (n = 109; 51.4%) had remarkably higher 1-year all-cause and cardiac re-hospitalization rates compared with their counterparts without NAFLD. Both event rates were particularly increased in those with advanced NAFLD fibrosis. NAFLD was associated with a 5-fold increased risk of 1-year all-cause re-hospitalization (adjusted-hazard ratio 5.05, 95% confidence intervals 2.78-9.10, pacute HF.
