Right ventricular (RV) function plays a pivotal role in advanced heart failure patients, especially for screening those who may benefit from left ventricular assist device (LVAD) implantation. We introduce RV contraction pressure index (RVCPI) as a new echo-Doppler parameter of RV function. The accuracy of RVCPI in detecting RV failure was compared with the criterion standard, the RV stroke work index (RVSWI) obtained through right heart catheterization in advanced heart failure patients referred for heart transplantation or LVAD implantation. Right heart catheterization and echo-Doppler were simultaneously performed in 94 consecutive patients referred to our center for advanced heart failure (ejection fraction (EF) 24 ± 8.8%, 40% NYHA functional class IV). RV stroke volume and invasive pulmonary pressures were used to obtain RVSWI. Simplified RVCPI (sRVCPI) was derived as TAPSE × (RV - right atrial pressure gradient). Close positive correlation between sRVCPI and RVSWI was found (r = 0.68; P rights reserved.

We sought to determine from key clinical outcomes whether catheter ablation of atrial fibrillation (AF) is associated with increased survival. Using routinely collected hospital data, ablation patients were matched to two control cohorts using direct and propensity score methodology. Four thousand nine hundred ninety-one ablation patients were matched 1:1 with general AF controls without ablation. Five thousand four hundred seven ablation patients were similarly matched to controls who underwent cardioversion. We examined the rates of ischemic stroke or transient ischemic attack (stroke/TIA), heart failure hospitalization, and death. Matched populations had very similar comorbidity profiles, including nearly identical CHA 2 DS 2 -VASc risk distribution ( p =0.6948 and p =0.8152 vs general AF and cardioversion cohorts). Kaplan-Meier models showed increased survival after ablation for all outcomes compared with both control cohorts ( p vs general AF, p =0.0087 for stroke/TIA, p vs cardioversion). Cox regression models also showed improved survival after ablation for all outcomes compared with the general AF cohort (hazard ratio [HR]=0.4, 95% confidence interval [95% CI]: 0.3-0.6, p stroke/TIA; HR=0.4, 95% CI: 0.2-0.6, p stroke/TIA; HR=0.4, 95% CI: 0.3-0.6, p stroke/TIA, and heart failure compared with a matched general AF population and a matched population who underwent cardioversion. Potential confounding of outcomes was minimized by very tight cohort matching.

To determine whether serum N-terminal pro-B-type natriuretic peptide (N-BNP), a biomarker of myocardial wall stress, is specific to acute heart failure (HF) in patients hospitalized with stroke. Case-control study. Tertiary hospital, Neurosciences Critical Care Unit and Stroke Unit. Consecutive patients with acute ischemic or hemorrhagic stroke who were evaluated for HF. None. Cases and controls were classified, respectively, as patients with or without HF, defined according to modified Framingham criteria. Seventy-two patients were evaluated, 39 with ischemic stroke, 22 with aneurysmal subarachnoid hemorrhage (SAH), and 11 with intracerebral hemorrhage (ICH). Thirty-four patients (47%) met criteria for HF, and 47 patients (65%) had systolic or diastolic left ventricular (LV) dysfunction on echocardiogram. Serum N-BNP was measured a median of 48 h following the onset of stroke and was increased (> 900 pg/ml) in 56 patients (78%), with higher levels in non-survivors (11898 +/- 12741 vs 4073 +/-5691; p = 0.001). In a multiple regression model, N-BNP elevation was not independently associated with HF (OR 5.4, 95% CI 0.8-36.0, p = 0.084). At a cut-off of 900 pg/ml, the sensitivity of N-BNP for HF was 94%, specificity 37%, positive predictive value (PPV) 57%, and negative predictive value (NPV) 88%. For systolic or diastolic LV dysfunction, the sensitivity of N-BNP was 89%, specificity 44%, PPV 75%, and NPV 69%. These results demonstrate that N-BNP elevation is not specific to HF or LV dysfunction in patients with acute ischemic stroke, SAH, and ICH.

Right heart failure occurs in various heart and pulmonary vascular diseases and may be fatal. We aimed to identify limitations in non-invasive measurements of right ventricular stroke volume in an animal model of right ventricular failure. Data from previous studies randomising rats to pulmonary trunk banding (PTB, n = 33) causing pressure-overload right ventricular failure or sham operation (n = 16) was evaluated retrospectively. We measured right ventricular stroke volume by high frequency echocardiography and magnetic resonance imaging (MRI). We found correlation between right ventricular stroke volume measured by echocardiography and MRI in the sham animals (r = 0.677, p = 0.004) but not in the PTB group. Echocardiography overestimated the stroke volume compared to MRI in both groups. Intra- and inter-observer variation did not explain the difference. Technical, physiological and anatomical issues in the pulmonary artery might explain why echocardiography over-estimates stroke volume. Flow acceleration close to the pulmonary artery banding can cause uncertainties in the PTB model and might explain the lack of correlation. In conclusion, we found a correlation in right ventricular stroke volume measured by echocardiography versus MRI in the sham group but not the PTB group. Echocardiography overestimated right ventricular stroke volume compared to MRI. (paper)

Abstract The aim of this study was to investigate the relationships between pulmonary function, respiratory muscle strength, perceived dyspnea, degree of fatigue, and activity of daily living with motor function and neurological status in stroke patients with stable congestive heart failure (CHF). This was a cohort study in a tertiary care medical center. Stroke patients with CHF and exertional dyspnea (New York Heart Association class I–III) were recruited. The baseline characteristics included duration of disease, Brunnstrom stage, spirometry, resting heart rate, resting oxyhemoglobin saturation (SpO2), maximal inspiratory pressure (MIP), maximal expiratory pressure (MEP), Borg scale, fatigue scale, and Barthel index. A total of 47 stroke patients (24 males, 23 females, mean age 65.9 ± 11.5 years) were included. The average Brunnstrom stages of affected limbs were 3.6 ± 1.3 over the proximal parts and 3.5 ± 1.4 over the distal parts of upper limbs, and 3.9 ± 0.9 over lower limbs. The average forced vital capacity (FVC) was 2.0 ± 0.8 L, with a predicted FVC% of 67.9 ± 18.8%, forced expiratory volume in the first second (FEV1) of 1.6 ± 0.7 L, predicted FEV1% of 70.6 ± 20.1%, FEV1/FVC of 84.2 ± 10.5%, and maximum mid-expiratory flow of 65.4 ± 29.5%. The average MIP and MEP were −52.9 ± 33.3 cmH2O and 60.8 ± 29.0 cmH2O, respectively. The Borg scale was 1.5 ± 0.8. MIP was negatively associated with the average Brunnstrom stage of the proximal (r = −0.318, P lower extremities (r = −0.288, P lower extremities (r = −0.311, P limbs. FVC was more strongly associated with MIP and MEP than predicted FVC%. FEV1/FVC may be used as a reference for the pulmonary dysfunction. PMID:27749577

The Mediterranean diet, which is palatable and easily achievable, has been associated with lower all-cause and cardiovascular disease (CVD) incidence and mortality. Data on heart failure (HF) and stroke types are lacking. The aim was to examine a Mediterranean diet in relation to incidence of myocardial infarction (MI), HF and stroke types in a Swedish prospective cohort. In a population-based cohort of 32,921 women, diet was assessed through a self-administered questionnaire. The modified Mediterranean diet (mMED) score was created based on high consumption of vegetables, fruits, legumes, nuts, whole grains, fermented dairy products, fish and monounsaturated fat, moderate intakes of alcohol and low consumption of red meat, on a 0-8 scale. Relative risks (RR) with 95% confidence intervals (CI), adjusted for potential confounders, were estimated by Cox proportional hazards regression models. During 10 y of follow-up (1998-2008), 1109 MIs, 1648 HFs, 1270 ischemic strokes and 262 total hemorrhagic strokes were ascertained. A high adherence to the mMED score (6-8), compared to low, was associated with a lower risk of MI (RR: 0.74, 95% CI: 0.61-0.90, p = 0.003), HF (RR: 0.79, 95% CI: 0.68-0.93, p = 0.004) and ischemic stroke (RR: 0.78, 95% CI: 0.65-0.93, p = 0.007), but not hemorrhagic stroke (RR: 0.88, 95% CI: 0.61-1.29, p = 0.53). Better adherence to a Mediterranean diet was associated with lower risk of MI, HF and ischemic stroke. The Mediterranean diet is most likely to be beneficial in primary prevention of all major types of atherosclerosis-related CVD. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Bioimpedance techniques may be appropriate for cardiac stroke volume (SV) monitoring since thoracic anatomical changes during the heart contraction reflect on the conductivity distribution. In some bioimpedance techniques, the electrical potential is calculated from the impedance distribution using Poisson's equation. That is called the forward problem and in many applications it is used inherently in the solution of the inverse problem—finding the impedance distribution from the electrical potentials. In this work, the forward problem was simulated using a realistic 3D hybrid phantom of the human thorax. The cardiac cycle of normal patients and patients suffering from cardiogenic pulmonary edema was simulated, including the effect of pulmonary blood perfusion during heart contraction. The forward problem was found to be most sensitive to SV when current was injected from the right breast toward the left scapula (−0.021 µV ml −1 ). Our simulations show that both the heart volume and lung conductivity affect the developing voltage; therefore in SV estimation, the lung conductivity and heart volume should be jointly estimated

Right ventricular (RV) systolic function has a critical role in determining the clinical outcome and success of using left ventricular assist devices (LVADs) in patients with refractory heart failure. Tissue Doppler and M-mode measurements of tricuspid systolic motion (tricuspid S' and tricuspid annular plane systolic excursion [TAPSE]) are the most currently used methods for the quantification of RV longitudinal function; RV deformation analysis by speckle-tracking echocardiography (STE) has recently allowed the analysis of global RV longitudinal function. Using cardiac catheterization as the reference standard, this study aimed at exploring the correlation between RV longitudinal function by STE and RV stroke work index (RVSWI) in patients referred for cardiac transplantation. Right-side heart catheterization and transthoracic echo Doppler were simultaneously performed in 41 patients referred for cardiac transplantation evaluation for advanced systolic heart failure. Thermodilution RV stroke volume and invasive pulmonary pressures were used to obtain RVSWI. RV longitudinal strain (RVLS) by STE was assessed averaging all segments in apical 4-chamber view (global RVLS) and by averaging RV free-wall segments (free-wall RVLS). Tricuspid S' and TAPSE were also calculated. No significant correlations were found for TAPSE or tricuspid S' with RVSWI (r = 0.14; r = 0.06; respectively). Close negative correlations between global RVLS and free-wall RVLS with the RVSWI were found (r = -0.75; r = -0.82; respectively; both P rights reserved.

How cardiovascular (CV) events affect progression to end-stage renal disease (ESRD), particularly in the setting of type 2 diabetes, remains uncertain. Observational study. 4,022 patients with type 2 diabetes, anemia, and chronic kidney disease from the Trial to Reduce Cardiovascular Events With Aranesp Therapy (TREAT). Postrandomization CV events. ESRD (defined as initiation of dialysis for >30 days, kidney transplantation, or refusal or nonavailability of renal replacement therapy) and post-ESRD mortality within 30 days and during overall follow-up after an intercurrent CV event. Population limited to clinical trial participants with diabetes and anemia. 155 of 652 (23.8%) ESRD cases occurred after an intercurrent CV event; 110 (16.9%) cases followed heart failure, 28 (4.3%) followed myocardial infarction, 12 (1.84%) followed stroke, and 5 (0.77%) followed multiple CV events. ESRD rate was higher within 30 days in individuals with an intercurrent CV event compared with those without an intercurrent event (HR, 22.2; 95% CI, 17.0-29.0). Compared to no intercurrent CV events, relative risks for ESRD were higher after the occurrence of heart failure overall (HR, 3.4; 95% CI, 2.7-4.2) and at 30 days (HR, 20.1; 95% CI, 14.5-27.9) than after myocardial infarction or stroke (Pfailure, are strongly associated with risk for ESRD. These findings underscore the need for kidney-specific therapies in addition to treatment of CV risk factors to lower ESRD incidence in diabetes. Copyright © 2017 National Kidney Foundation, Inc.

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.
Background Treatment burden can be defined as the self-care practices that patients with chronic illness must perform to respond to the requirements of their healthcare providers, as well as the impact that these practices have on patient functioning and well being. Increasing levels of treatment burden may lead to suboptimal adherence and negative outcomes. Systematic review of the qualitative literature is a useful method for exploring the patient experience of care, in this case the experience of treatment burden. There is no consensus on methods for qualitative systematic review. This paper describes the methodology used for qualitative systematic reviews of the treatment burdens identified in three different common chronic conditions, using stroke as our exemplar. Methods Qualitative studies in peer reviewed journals seeking to understand the patient experience of stroke management were sought. Limitations of English language and year of publication 2000 onwards were set. An exhaustive search strategy was employed, consisting of a scoping search, database searches (Scopus, CINAHL, Embase, Medline & PsycINFO) and reference, footnote and citation searching. Papers were screened, data extracted, quality appraised and analysed by two individuals, with a third party for disagreements. Data analysis was carried out using a coding framework underpinned by Normalization Process Theory (NPT). Results A total of 4364 papers were identified, 54 were included in the review. Of these, 51 (94%) were retrieved from our database search. Methodological issues included: creating an appropriate search strategy; investigating a topic not previously conceptualised; sorting through irrelevant data within papers; the quality appraisal of qualitative research; and the use of NPT as a novel method of data analysis, shown to be a useful method for the purposes of this review. Conclusion The creation of our search strategy may be of particular interest to other researchers carrying out

Cardiopulmonary exercise testing (CPET) plays an important role in properly phenotyping signs and symptoms of heart failure with preserved ejection fraction (HFpEF). The prognostic value of CPET is strengthened when accompanied by cardiac hemodynamic measurements. Although recognized as the "gold" standard, cardiac catheterization is impractical for routine CPET. Thus, advancing the scientific/methodologic understanding of noninvasive techniques for exercise cardiac hemodynamic assessment is clinically impactful in HFpEF. This study tested the concurrent validity of noninvasive acetylene gas (C2H2) uptake, echocardiography (ECHO), and oxygen pulse (O2pulse) for measuring/predicting exercise stroke volume (SV) in HFpEF. Eighteen white HFpEF and 18 age-/sex-matched healthy controls participated in upright CPET (ages, 69 ± 9 yr vs 63 ± 9 yr). At rest, 20 W, and peak exercise, SV was measured at steady-state via C2H2 rebreathe (SVACET) and ECHO (SVECHO), whereas O2pulse was derived (=V˙O2/HR). Resting relationships between SVACET and SVECHO, SVECHO and O2pulse, or SVACET and O2pulse were significant in HFpEF (R = 0.30, 0.36, 0.67), but not controls (R = 0.07, 0.01, 0.09), respectively. Resting relationships persisted to 20 W in HFpEF (R = 0.70, 0.53, 0.70) and controls (R = 0.05, 0.07, 0.21), respectively. Peak exercise relationships were significant in HFpEF (R = 0.62, 0.24, 0.64), but only for SVACET versus O2pulse in controls (R = 0.07, 0.04, 0.33), respectively. Standardized standard error of estimate between techniques was strongest in HFpEF at 20 W: SVACET versus SVECHO = 0.57 ± 0.22; SVECHO versus O2pulse = 0.71 ± 0.28; SVACET versus O2pulse = 0.56 ± 0.22. Constituting a clinically impactful step towards construct validation testing, these data suggest SVACET, SVECHO, and O2pulse demonstrate moderate-to-strong concurrent validity for measuring/predicting exercise SV in HFpEF.

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

A study of 209 consecutive cases of hypertension, seen at the cardiac unit of the University College Hospital, Ibadan, Nigeria, showed that heart failure occurred more commonly in patients who were in the low socio-economic class. All those who had a haematocrit below 30% had heart failure. The lower the serum albumin, the greater the likelihood of developing heart failure. Hypertensives who were heavy alcohol drinkers were very prone to heart failure while a significant proportion of those who had cardiomegaly or cardiomegaly with aortic unfolding on chest x-ray had heart failure. Age, sex, Hb genotype, obesity and retinal changes had no influence on the development of heart failure. It is concluded that there are other factors, besides hypertension, which precipitate heart failure in Nigerian hypertensives. This may be responsible for the high incidence of heart failure among Nigerian with hypertension.

During normal aging, the heart undergoes functional, morphological and cellular changes. Although aging per se does not lead to the expression of heart failure, it is likely that age-associated changes lower the threshold for the manifestation of signs and symptoms of heart failure. In patients, the

Neurocardiology is an emerging specialty that addresses the interaction between the brain and the heart, that is, the effects of cardiac injury on the brain and the effects of brain injury on the heart. This review article focuses on cardiac dysfunction in the setting of stroke such as ischemic stroke, brain hemorrhage, and subarachnoid hemorrhage. The majority of post-stroke deaths are attributed to neurological damage, and cardiovascular complications are the second leading cause of post-stroke mortality. Accumulating clinical and experimental evidence suggests a causal relationship between brain damage and heart dysfunction. Thus, it is important to determine whether cardiac dysfunction is triggered by stroke, is an unrelated complication, or is the underlying cause of stroke. Stroke-induced cardiac damage may lead to fatality or potentially lifelong cardiac problems (such as heart failure), or to mild and recoverable damage such as neurogenic stress cardiomyopathy and Takotsubo cardiomyopathy. The role of location and lateralization of brain lesions after stroke in brain-heart interaction; clinical biomarkers and manifestations of cardiac complications; and underlying mechanisms of brain-heart interaction after stroke, such as the hypothalamic-pituitary-adrenal axis; catecholamine surge; sympathetic and parasympathetic regulation; microvesicles; microRNAs; gut microbiome, immunoresponse, and systemic inflammation, are discussed. © 2017 American Heart Association, Inc.

Vitamin D is principally known for its role in calcium homeostasis, but preclinical studies implicate multiple pathways through which vitamin D may affect cardiovascular function and influence risk for heart failure. Many adults with cardiovascular disease have low vitamin D status, making it a potential therapeutic target. We review the rationale and potential role of vitamin D supplementation in the prevention and treatment of chronic heart failure. Substantial observational evidence has associated low vitamin D status with the risk of heart failure, ventricular remodeling, and clinical outcomes in heart failure, including mortality. However, trials assessing the influence of vitamin D supplementation on surrogate markers and clinical outcomes in heart failure have generally been small and inconclusive. There are insufficient data to recommend routine assessment or supplementation of vitamin D for the prevention or treatment of chronic heart failure. Prospective trials powered for clinical outcomes are warranted.

The prevalence of heart failure substantially increases with advancing age. Nevertheless, heart failure in the elderly is commonly under-diagnosed, because dyspnoea and fatigue are often attributed to the natural process of aging. Age-related alterations of the cardiovascular system and the presence of multiple comorbidities not only change the clinical features of heart failure, but also have an impact on heart failure treatment in this population. Cautious uptitration of the individual drugs and vigorous clinical and laboratory monitoring is mandatory to avoid undesired side effects. Although guideline-recommended heart failure therapy is derived from trials that included mainly middle-aged patients with few comorbidities, it has proven beneficial even in the very elderly. Today, guideline-recommended heart failure therapy is still too often withheld from elderly patients out of fear of potential side effects.

Heart failure is a very common condition in elderly people, particularly those living away from home, in institutional care. The main objective of a study was to find out whether patients with heart failure admitted to a nursing home benefit or not from the same ultrasound assessment as the general population. The secondary objective was to analyse the management of residents with heart failure living in institutional care. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

Heart failure affects over 5 million people in the United States and carries a high rate of mortality. Ivabradine, a new agent has been added to the current medical options for managing heart failure. It is a selective funny current (If) inhibitor in sinoatrial node and slows its firing rate, prolonging diastolic depolarization without a negative inotropic effect. Ivabradine was only recently approved by Food and Drug administration after the results of Systolic Heart Failure Treatment with the If Inhibitor Ivabradine (SHIFT) trial, for a reduction in rehospitalizations from chronic heart failure. This trial assessed patients with stable heart failure with reduced ejection fraction and a heart rate of at least 70 beats per minute at rest on maximally tolerated beta-blocker therapy and demonstrated statistically significant reduction in heart failure hospitalization and deaths. Additionally, ivabradine has been associated with reduced cardiac remodeling, reduced heart rate variability, improvement in exercise tolerance, improved heart failure class of New York Heart Association, and better quality of life. It has also been tried in other conditions, such as inappropriate sinus tachycardia and cardiogenic shock, and is currently in phase II trial for patients with newly diagnosed multiple organ dysfunction syndrome. © The Author(s) 2015.

The relative and absolute risks of stroke and heart failure attributable to atrial fibrillation (AF) have not been sufficiently examined. A prospective study of 23,731 community-dwelling Japanese individuals was conducted. Participants were divided into two groups based on the presence or absence of prevalent AF (n = 338 and n = 23,393, respectively). Excess events (EE) due to AF and relative risks (RRs) determined using the non-AF group as the reference for incident stroke and heart failure were estimated using Poisson regression stratified by age groups (middle-aged: 40-69 years old; elderly: 70 years of age or older) after adjustment for sex and age. There were 611 cases of stroke and 98 cases of heart failure during the observation period (131,088 person-years). AF contributed to a higher risk of stroke both in middle-aged individuals (EE 10.4 per 1000 person-years; RR 4.88; 95% confidence interval [CI], 2.88-8.29) and elderly individuals (EE 18.3 per 1000 person-years; RR 3.05; 95% CI, 2.05-4.54). AF also contributed to a higher risk of heart failure in middle-aged individuals (EE 3.7 per 1000 person-years; RR 8.18; 95% CI, 2.41-27.8) and elderly individuals (EE 15.4 per 1000 person-years; RR 7.82; 95% CI, 4.11-14.9). Results obtained from multivariate-adjusted analysis were similar (stroke: EE 8.9 per 1000 person-years; RR 4.40; 95% CI, 2.57-7.55 in middle-aged and EE 17.4 per 1000 person-years; RR 2.97; 95% CI, 1.99-4.43 in elderly individuals; heart failure: EE 3.1 per 1000 person-years; RR 7.22; 95% CI, 2.06-25.3 in middle-aged and EE 14.1 per 1000 person-years; RR 7.41; 95% CI, 3.86-14.2 in elderly individuals). AF increased the risk of stroke by the same magnitude as that reported previously in Western countries. AF increased the RR of heart failure more than that in Western populations.

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.

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.

We examined the risk of stroke or systemic embolism (SSE) conferred by heart failure (HF) and left ventricular systolic dysfunction (LVSD) in the Apixaban for Reduction in Stroke and Other Thromboembolic Events in Atrial Fibrillation Trial (ARISTOTLE), as well as the effect of apixaban versus warfarin. The risk of a number of outcomes, including the composite of SSE or death (to take account of competing risks) and composite of SSE, major bleeding, or death (net clinical benefit) were calculated in 3 patient groups: (1) no HF/no LVSD (n=8728), (2) HF/no LVSD (n=3207), and (3) LVSD with/without symptomatic HF (n=2736). The rate of both outcomes was highest in patients with LVSD (SSE or death 8.06; SSE, major bleeding, or death 10.46 per 100 patient-years), intermediate for HF but preserved LV systolic function (5.32; 7.24), and lowest in patients without HF or LVSD (1.54; 5.27); each comparison PARISTOTLE patients, the apixaban/warfarin hazard ratio for SSE or death was 0.89 (95% confidence interval, 0.81-0.98; P=0.02); for SSE, major bleed, or death it was 0.85 (0.78-0.92; P<0.001). There was no heterogeneity of treatment effect across the 3 groups. Patients with LVSD (with/without HF) had a higher risk of SSE or death (but similar rate of SSE) compared with patients with HF but preserved LV systolic function; both had a greater risk than patients without either HF or LVSD. Apixaban reduced the risk of both outcomes more than warfarin in all 3 patient groups. URL: http://www.clinicaltrials.gov. Unique identifier: NCT00412984.

The combination of angiotensin-converting enzyme (ACE) inhibitors and β-adrenergic receptor (βAR) blockers remains the essential component of heart failure (HF) pharmacotherapy. However, individual patient responses to these pharmacotherapies vary widely. The variability in response cannot be explained entirely by clinical characteristics, and genetic variation may play a role. The purpose of this chapter is to examine the current knowledge in the field of beta-blocker and ACE inhibitor pharmacogenetics in HF. β-blocker and ACE inhibitor pharmacogenetic studies performed in patients with HF were identified from the PubMed database from 1966 to July 2011. Thirty beta-blocker and 10 ACE inhibitor pharmacogenetic studies in patients with HF were identified.The ACE deletion variant was associated with greater survival benefit from ACE inhibitors and beta-blockers compared with the ACE insertion. Ser49 in the β1AR, the insertion in the α2CAR, and Gln41 in G protein-coupled receptor (GPCR) kinase (GRK)-5 are associated with greater survival benefit from β-blockers, compared with Gly49, the deletion, and Leu41, respectively. However, many of these associations have not been validated. The HF pharmacogenetic literature is still in its very early stages, but there are promising candidate genetic variants that may identify which HF patients are most likely to benefit from beta-blockers and ACE inhibitors and patients that may require additional therapies.

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.

Full Text Available Significant progress has been made in the last few years in the management of heart failure. In particular several trials have given significant results. It has become apparent that heart failure may be prevented in some patients by treatment of risk factors such as coronary artery disease. Experience with angiotensin-converting enzyme (ACE inhibitors has shown that the survival and symptomatic benefits do last in the long term, and confirm that they are the first-line treatment in heart failure. The results of a number of trials using the angiotensin receptor blockers (ARBs candesartan, valsartan and losartan are presented and discussed. There is also some experience now in the use of candesartan for patients with heart failure and preserved left ventricular systolic function. The COMET trial compared the β-blockers carvedilol and metoprolol tartrate, and suggests that there may be differences in clinical effect between β-blockers. The selective aldosterone receptor blocker eplerenone was evaluated in the EPHESUS trial in post-MI patients with signs of heart failure. Based on these clinical trials, heart failure guidelines are now being updated.

Secondary hyperparathyroidism (SHPT) is a well-known pathophysiologic feature of chronic renal failure. In recent years, SHPT has become recognized as a complication of the aldosteronism associated with congestive heart failure and where excretory Ca 2+ and Mg 2+ wasting results in plasma-ionized hypocalcemia and hypomagnesemia. Elevations in plasma parathyroid hormone have adverse systemic consequences, including intracellular Ca 2+ overloading of myocytes and vascular smooth muscle with the induction of oxidative stress. Herein, we briefly review the presence and adverse outcomes of SHPT in persons with heart failure. Copyright © 2017 Southern Society for Clinical Investigation. Published by Elsevier Inc.

Full Text Available Survival in patients with heart failure remains very poor, and is worse than that for most common cancers, including bowel cancer in men and breast cancer in women. The renin-angiotensin-aldosterone system (RAAS is not completely blocked by angiotensin-converting enzyme (ACE inhibition. Blockade of the RAAS at the AT1-receptor has the theoretical benefit of more effective blockade of the actions of angiotensin II. ACE inhibitors (ACE-Is prevent the breakdown of bradykinin: this has been blamed for some of the unwanted effects of ACE-Is although bradykinin may have advantageous effects in heart failure. Consequently, ACE-Is and ARBs might be complementary or even additive treatments; recent trials have tested these hypotheses.

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

Studies from the USA have reported that sleep apnoea is common in congestive heart failure (CHF), with Cheyne-Stokes respiration (CSR) being the most frequent type of sleep-disordered breathing (SDB) in these patients. Within the present study, the authors sought to assess the prevalence and type of SDB among CHF patients in Germany. A total of 203 CHF patients participated in this prospective multicentre study. All patients were stable in New York Heart Association classes II and III and had a left ventricular ejection fraction (LVEF)10.h(-1), obstructive sleep apnoea (OSA) occurred in 43% (n=88) and CSR in 28% (n=57) of patients. The prevalence of sleep-disordered breathing is high in patients with stable severe congestive heart failure from a European population. As sleep-disordered breathing may have a negative impact on the prognosis of congestive heart failure, a sleep study should be performed in every patient with congestive heart failure and a left ventricular ejection fraction of <40%. This diagnostic approach should probably be adopted for all of these patients irrespective of the presence of sleep-related symptoms.

The CHA 2 DS 2 -VASc stroke score (congestive heart failure, hypertension, age ≥75 (doubled), diabetes mellitus, prior stroke or transient ischemic attack (doubled), vascular disease, age 65-74, female) is used in most guidelines for risk stratification in atrial fibrillation (AF), but most data for this score have been derived in Western populations. Ethnic differences in stroke risk may be present. Our objective was to investigate risk factors for stroke in AF and application of the CHA 2 DS 2 -VASc score in an Asian AF population from Korea. A total of 5855 oral anticoagulant-naive nonvalvular AF patients aged ≥20 years were enrolled from Korea National Health Insurance Service Sample cohort from 2002 to 2008 and were followed up until December 2013. The incidence rates (per 100 person-years) of ischemic stroke were 3.32 in the total population, being 0.23 in low-risk (CHA 2 DS 2 -VASc score 0 [male] or 1 [female]) and 4.59 in high-risk patients (CHA 2 DS 2 -VASc ≥2). Incidence rates of ischemic stroke or the composite thromboembolism end point showed a clear increase with increasing CHA 2 DS 2 -VASc score. On multivariable analysis, significant associations between CHA 2 DS 2 -VASc risk factors and ischemic stroke were observed; however, the significance of vascular disease or diabetes mellitus was attenuated after multivariate adjustment, and female sex (hazard ratio, 0.73; 95% confidence interval, 0.64-0.84) had a lower risk of ischemic stroke than males. Patients who were categorized as low risk consistently had an event rate Heart Association, Inc.

Heart failure in children presents important characteristic features different from adult congestive failure, from a pathophysiological and mostly from an etiopathogenic point of view. Heart failure in children is, in most cases, a consequence of congenital structural cardiac abnormalities that remained unoperated, underwent a palliative operation or presented post-surgery complications, or of cardiomyopathy. Based on the nature of the clinical presentation, new onset heart failure can be dif...

Heart failure is a life-threatening disease and addressing it should be considered a global health priority. At present, approximately 26 million people worldwide are living with heart failure. The outlook for such patients is poor, with survival rates worse than those for bowel, breast or prostate cancer. Furthermore, heart failure places great stresses on patients, caregivers and healthcare systems. Demands on healthcare services, in particular, are predicted to increase dramatically over the next decade as patient numbers rise owing to ageing populations, detrimental lifestyle changes and improved survival of those who go on to develop heart failure as the final stage of another disease. It is time to ease the strain on healthcare systems through clear policy initiatives that prioritize heart failure prevention and champion equity of care for all. Despite the burdens that heart failure imposes on society, awareness of the disease is poor. As a result, many premature deaths occur. This is in spite of the fact that most types of heart failure are preventable and that a healthy lifestyle can reduce risk. Even after heart failure has developed, premature deaths could be prevented if people were taught to recognize the symptoms and seek immediate medical attention. Public awareness campaigns focusing on these messages have great potential to improve outcomes for patients with heart failure and ultimately to save lives. Compliance with clinical practice guidelines is also associated with improved outcomes for patients with heart failure. However, in many countries, there is considerable variation in how closely physicians follow guideline recommendations. To promote equity of care, improvements should be encouraged through the use of hospital performance measures and incentives appropriate to the locality. To this end, policies should promote the research required to establish an evidence base for performance measures that reflect improved outcomes for patients

Heart failure is an important community health problem. Prevalence and incidence of heart failure have continued to rise over the years. Despite recent advances in heart failure therapy, prognosis is still poor, rehospitalization rate is very high, and quality of life is worse. Co-morbidities in heart failure have negative impact on clinical course of the disease, further impair prognosis, and add difficulties to treatment of clinical picture. Therefore, successful management of co-morbidities is strongly recommended in addition to conventional therapy for heart failure. One of the most common co-morbidities in heart failure is presence of iron deficiency and anemia. Current evidence suggests that iron deficiency and anemia are more prevalent in patients with heart failure and reduced ejection fraction, as well as those with heart failure and preserved ejection fraction. Moreover, iron deficiency and anemia are referred to as independent predictors for poor prognosis in heart failure. There is strong relationship between iron deficiency or anemia and severity of clinical status of heart failure. Over the last two decades, many clinical investigations have been conducted on clinical effectiveness of treatment of iron deficiency or anemia with oral iron, intravenous iron, and erythropoietin therapies. Studies with oral iron and erythropoietin therapies did not provide any clinical benefit and, in fact, these therapies have been shown to be associated with increase in adverse clinical outcomes. However, clinical trials in patients with iron deficiency in the presence or absence of anemia have demonstrated considerable clinical benefits of intravenous iron therapy, and based on these positive outcomes, iron deficiency has become target of therapy in management of heart failure. The present report assesses current approaches to iron deficiency and anemia in heart failure in light of recent evidence.

Many of the primary clinical manifestations of heart failure (HF) are due to fluid retention, and treatments targeting congestion play a central role in HF management. Diuretic therapy remains the cornerstone of congestion treatment, and diuretics are prescribed to the majority of HF patients. Despite this ubiquitous use, there is limited evidence from prospective randomized studies to guide the use of diuretics. With the chronic use of diuretic and usually in advanced stages of HF, diuretics may fail to control salt and water retention. This review describes the mechanism of action of available diuretic classes, reviews their clinical use based on scientific evidence and discusses strategies to overcome diuretic resistance.

Heart failure (HF) is accompanied by an autonomic imbalance that is almost always characterized by both increased sympathetic activity and withdrawal of vagal activity. Experimentally, vagal stimulation has been shown to exert profound antiarrhythmic activity and to improve cardiac function and survival in HF models. A open-label pilot clinical study in 32 patients with chronic HF has shown safety and tolerability of chronic vagal stimulation associated with subjective (improved quality of life and 6-min walk test) and objective improvements (reduced left ventricular systolic volumes and improved left ventricular ejection fraction). Three larger clinical studies, including a phase III trial are currently ongoing and will evaluate the clinical role of this new approach.

This review describes the numerous and complex molecular systems that are either known players or candidates in heart failure(HF). All systems whose genetic background has been investigated to date in HF are listed and discussed. Discussion also includes functional notes and known genetic polymorphisms already investigated in HF or candidates that have not yet been investigated. Despite substantial research on HF, relatively few coordinated studies have been conducted that assign precise risk to specific genetic polymorphisms. Identification of risk associated with genetic variations and subsequent translation of genetic knowledge into clinical practice will likely progress only in cases of large coordinated studies based on identical standards. The potential result will be a more accurate definition of HF identified as an evolving complex of cardiovascular diseases.

Atherosclerotic renal artery disease presents with a broad spectrum of clinical features, including heart failure as well as hypertension, and renal failure. Although recent randomized controlled trials failed to demonstrate renal artery stenting can reduce blood pressure or the number of cardiovascular or renal events more so than medical therapy, increasing attention has been paid to flash pulmonary edema and congestive heart failure associated with atherosclerotic renal artery disease. This clinical entity "renovascular heart failure" is diagnosed retrospectively. Given the increasing global burden of heart failure, this review highlights the background and catheter-based therapeutic aspects for renovascular heart failure.

Hospitalizations due to heart failure are increasing steadily despite advances in medicine. Patients hospitalized for worsening heart failure have high mortality in hospital and within the months following discharge. Kidney dysfunction is associated with adverse outcomes in heart failure patients. Recent evidence suggests that both deterioration in kidney function and renal congestion are important prognostic factors in heart failure. Kidney congestion in heart failure results from low cardiac output (forward failure), tubuloglomerular feedback, increased intra-abdominal pressure or increased venous pressure. Regardless of the cause, renal congestion is associated with increased morbidity and mortality in heart failure. The impact on outcomes of renal decongestion strategies that do not compromise renal function should be explored in heart failure. These studies require novel diagnostic markers that identify early renal damage and renal congestion and allow monitoring of treatment responses in order to avoid severe worsening of renal function. In addition, there is an unmet need regarding evidence-based therapeutic management of renal congestion and worsening renal function. In the present review, we summarize the mechanisms, diagnosis, outcomes, prognostic markers and treatment options of renal congestion in heart failure.

In atrial fibrillation, stroke risk is assessed by the CHA 2 DS 2 -VASc score. Heart failure is included in CHA 2 DS 2 -VASc, but the rationale is uncertain. Our objective was to test if heart failure is a risk factor for stroke, independent of other risk factors in CHA 2 DS 2 -VASc. We studied 300 839 patients with atrial fibrillation in the Swedish Patient Register 2005-11. Three definitions of heart failure were used in order to assess the robustness of the results. In the main analysis, heart failure was defined by a hospital discharge diagnosis of heart failure as first or second diagnosis and a filled prescription of a diuretic within 3 months before index + 30 days. The second definition counted first or second discharge diagnoses failure diagnosis in open or hospital care before index + 30 days. Associations with outcomes were assessed with multivariable Cox analyses. Patients with heart failure were older (80.5 vs. 74.0 years, P failure and 3.1% without. Adjustment for the cofactors in CHA 2 DS 2 -VASc eradicated the difference in stroke risk between patients with and without heart failure (hazard ratio 1.01 with 95% confidence interval 0.96-1.05). The area under the receiver operating characteristic curve for CHA 2 DS 2 -VASc was not improved by points for heart failure. A clinical diagnosis of heart failure was not an independent risk factor for stroke in patients with atrial fibrillation, which may have implications for anticoagulation management. © 2018 The Authors.

To determine the prevalence of heart failure (HF) in nursing home residents and to gain insight into the clinical characteristics of residents with heart failure. Multi-centre, observational, cross-sectional study. 501 nursing home residents aged 65 years and over, in a department for chronic somatic diseases or a psychogeriatric department, participated in this study. The diagnosis of HF and the related characteristics were based on data collected from clinical examinations for heart failure (including history, physical examination, ECG, cardiac markers and echocardiography), patient records and questionnaires. A panel of two cardiologists and an internist-geriatrician made the final diagnosis of HF. The prevalence of HF in nursing home residents was 33%. Dyspnoea, oedema and a history of cardiac disease were more common in residents with heart failure. Diabetes mellitus and chronic obstructive pulmonary disease also appeared to be more prevalent in this group. In 54% of the residents with HF, the diagnosis had not previously been made. Diagnosis of HF was not confirmed by the expert panel in 31% of residents with a history of HF. Heart failure does indeed appear to be very prevalent in nursing home residents. Heart failure had not been previously diagnosed in many cases but also a previous diagnosis of heart failure could be disproved in many participants. It is therefore important that the diagnostic process for heart failure in nursing home residents be improved.
Increased intracardiac filling pressure or congestion causes symptoms and leads to hospital admissions in patients with heart failure, regardless of their systolic function. A history of hospital admission, in turn, predicts further hospitalizations and morbidity, and a higher number of hospitalizations determine higher mortality. Congestion is therefore the driving force of the natural history of heart failure. Congestion is the syndrome shared by heart failure with preserved and reduced systolic function. These two conditions have almost identical morbidity, mortality, and survival because the outcomes are driven by congestion. A small difference in favor of heart failure with preserved systolic function comes from decreased ejection fraction and left ventricular remodeling which is only present in heart failure with decreased systolic function. The magnitude of this difference reflects the contribution of decreased systolic function and ventricular remodeling to the progression of heart failure. The only treatment available for congestion is fluid removal via diuretics, ultrafiltration, or dialysis. It is the only treatment that works equally well for heart failure with reduced and preserved systolic function because it affects congestion, the main pathogenetic feature of the disease. Diuretics are pathogenetic therapy for heart failure. PMID:21403798

Heart failure patients are predisposed to develop arrhythmias. Supraventricular arrhythmias can exacerbate the heart failure symptoms by decreasing the effective cardiac output and their control require pharmacological, electrical, or catheter-based intervention. In the setting of atrial flutter or atrial fibrillation, anticoagulation becomes paramount to prevent systemic or cerebral embolism. Patients with heart failure are also prone to develop ventricular arrhythmias that can present a challenge to the managing clinician. The management strategy depends on the type of arrhythmia, the underlying structural heart disease, the severity of heart failure, and the range from optimization of heart failure therapy to catheter ablation. Patients with heart failure, irrespective of ejection fraction are at high risk for developing sudden cardiac death, however risk stratification is a clinical challenge and requires a multiparametric evaluation for identification of patients who should undergo implantation of a cardioverter defibrillator. Finally, patients with heart failure can also develop symptomatic bradycardia, caused by sinus node dysfunction or atrio-ventricular block. The treatment of bradycardia in these patients with pacing is usually straightforward but needs some specific issue. PMID:29367535

The obesity epidemic is contributing substantially to the burden of cardiovascular disease including heart disease and congestive heart failure, in the United States and the rest of the world. Overnutrition as a driver of obesity, promotes alterations in fatty acid, lipid, and glucose metabolism that influence myocardial function and progression of heart failure from diastolic to systolic failure. The association of progressive heart failure and progressive chronic kidney disease is well documented and often referred to as the cardiorenal syndrome, as well as a prognosticator for cerebrovascular disease (e.g. stroke). Whether the relationship between obesity, heart disease/failure and risk for chronic kidney disease and stroke is direct or a confluence of risk factors is poorly understood. Copyright © 2013 S.

Thrombin is a critical element of crosstalk between pathways contributing to worsening of established heart failure (HF). The aim of this study is to explore the efficacy and safety of rivaroxaban 2.5 mg bid compared with placebo (with standard care) after an exacerbation of HF in patients with reduced ejection fraction (HF-rEF) and documented coronary artery disease. This is an international prospective, multicentre, randomized, double-blind, placebo-controlled, event-driven study of approximately 5000 patients for a targeted 984 events. Patients must have a recent symptomatic exacerbation of HF, increased plasma concentrations of natriuretic peptides (B-type natriuretic peptide ≥200 pg/mL or N-terminal pro-B-type natriuretic peptide ≥800 pg/mL), with left ventricular ejection fraction ≤40% and coronary artery disease. Patients requiring anticoagulation for atrial fibrillation or other conditions will be excluded. After an index event (overnight hospitalization, emergency department or observation unit admission, or unscheduled outpatient parenteral treatment for worsening HF), patients will be randomized 1:1 to rivaroxaban or placebo (with standard of care). The primary efficacy outcome event is a composite of all-cause mortality, myocardial infarction or stroke. The principal safety outcome events are the composite of fatal bleeding or bleeding into a critical space with potential permanent disability, bleeding events requiring hospitalization and major bleeding events according to International Society on Thrombosis and Haemostasis bleeding criteria. COMMANDER HF is the first prospective study of a target-specific oral antithrombotic agent in HF. It will provide important information regarding rivaroxaban use following an HF event in an HF-rEF patient population with coronary artery disease. © 2015 The Authors.

Full Text Available Cognitive impairment (CI is increasingly recognized as a common adverse consequence of heart failure (HF. Although the exact mechanisms remain unclear, microembolism, chronic or intermittent cerebral hypoperfusion, and/or impaired cerebral vessel reactivity that lead to cerebral hypoxia and ischemic brain damage seem to underlie the development of CI in HF. Cognitive decline in HF is characterized by deficits in one or more cognition domains, including attention, memory, executive function, and psychomotor speed. These deficits may affect patients’ decision-making capacity and interfere with their ability to comply with treatment requirements, recognize and self-manage disease worsening symptoms. CI may have fluctuations in severity over time, improve with effective HF treatment or progress to dementia. CI is independently associated with disability, mortality, and decreased quality of life of HF patients. It is essential therefore for health professionals in their routine evaluations of HF patients to become familiar with assessment of cognitive performance using standardized screening instruments. Future studies should focus on elucidating the mechanisms that underlie CI in HF and establishing preventive strategies and treatment approaches.
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.

Background Low health literacy affects millions of Americans, putting those who are affected at a disadvantage and at risk for poorer health outcomes. Low health literacy can act as a barrier to effective disease self-management; this is especially true for chronic diseases such as heart failure (HF) that require complicated self-care regimens. Purpose This systematic review examined quantitative research literature published between 1999 and 2014 to explore the role of health literacy among HF patients. The specific aims of the systematic review are to (1) describe the prevalence of low health literacy among HF patients, (2) explore the predictors of low health literacy among HF patients, and (3) discuss the relationship between health literacy and HF self-care and common HF outcomes. Methods A systematic search of the following databases was conducted, PubMed, CINAHL Plus, Embase, PsycINFO, and Scopus, using relevant keywords and clear inclusion and exclusion criteria. Conclusions An average of 39% of HF patients have low health literacy. Age, race/ethnicity, years of education, and cognitive function are predictors of health literacy. In addition, adequate health literacy is consistently correlated with higher HF knowledge and higher salt knowledge. Clinical Implications Considering the prevalence of low health literacy among in the HF population, nurses and healthcare professionals need to recognize the consequences of low health literacy and adopt strategies that could minimize its detrimental effect on the patient's health outcomes.

Full Text Available A review of the definition and classification of heart failure, updated since the recent 2016 European Society of Cardiology guidelines for the diagnosis and treatment of acute and chronic heart failure. Heart failure is defined by the European Society of Cardiology (ESC as a clinical syndrome characterised by symptoms such as shortness of breath, persistent coughing or wheezing, ankle swelling and fatigue, that may be accompanied by the following signs: jugular venous pressure, pulmonary crackles, increased heart rate and peripheral oedema. However, these signs may not be present in the early stages and in patients treated with diuretics. When apparent, they are due to a structural and/or functional cardiac abnormality, leading to systolic and/or diastolic ventricular dysfunction, resulting in a reduced cardiac output and/or elevated intra- cardiac pressures at rest or during stress. According to the most recent ESC guidelines the initial evaluation of patients with suspected heart failure should include a clinical history and physical examination, laboratory assessment, chest radiography, and electrocardiography. Echocardiography can confirm the diagnosis. Beyond detecting myocardial abnormality, other impairments such as abnormalities of the valves, pericardium, endocardium, heart rhythm, and conduction may be found. The identification of the underlying aetiology is pivotal for the diagnosis of heart failure and its treatment. The authors review the definitions and classifications of heart failure.
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

Heart failure is a global public health problem that affects more than 26 million people worldwide. The global burden of heart failure is growing and is expected to increase substantially with the ageing of the population. Heart failure with reduced ejection fraction accounts for approximately 50% of all cases of heart failure in the United States and is associated with substantial morbidity and reduced quality of life. Several diseases, such as myocardial infarction, certain infectious diseases and endocrine disorders, can initiate a primary pathophysiological process that can lead to reduced ventricular function and to heart failure. Initially, ventricular impairment is compensated for by the activation of the sympathetic nervous system and the renin-angiotensin-aldosterone system, but chronic activation of these pathways leads to worsening cardiac function. The symptoms of heart failure can be associated with other conditions and include dyspnoea, fatigue, limitations in exercise tolerance and fluid accumulation, which can make diagnosis difficult. Management strategies include the use of pharmacological therapies and implantable devices to regulate cardiac function. Despite these available treatments, heart failure remains incurable, and patients have a poor prognosis and high mortality rate. Consequently, the development of new therapies is imperative and requires further research.

Full Text Available Heart failure (HF is a chronic clinical syndrome characterized by the reduction in left ventricular (LV function and it represents one of the most important causes of morbidity and mortality worldwide. Despite considerable advances in pharmacological treatment, HF represents a severe clinical and social burden. Sympathetic outflow, characterized by increased circulating catecholamines (CAs biosynthesis and secretion, is peculiar in HF and sympatholytic treatments (as β-blockers are presently being investigated for the treatment of this disease. Adrenal gland secretes Epinephrine (80% and Norepinephrine (20% in response to acetylcholine stimulation of nicotinic cholinergic receptors on the chromaffin cell membranes. This process is regulated by adrenergic receptors (ARs: α2ARs inhibit CA release through coupling to inhibitory Gi-proteins, and βARs (mainly β2ARs stimulate CA release through coupling to stimulatory Gs-proteins. All ARs are G-protein-coupled receptors (GPCRs and GPCR kinases (GRKs regulate their signaling and function. Adrenal GRK2-mediated α2AR desensitization and downregulation are increased in HF and seem to be a fundamental regulator of CA secretion from the adrenal gland. Consequently, restoration of adrenal a2AR signaling through the inhibition of GRK2 is a fascinating sympatholytic therapeutic strategy for chronic HF. This strategy could have several significant advantages over existing HF pharmacotherapies (antiadrenergic, such as bAR-blockers minimizing side-effects on extra-cardiac tissues and reducing the chronic activation of the renin–angiotensin–aldosterone and endothelin systems.The role of adrenal ARs in regulation of sympathetic hyperactivity opens interesting perspectives in understanding pathophysiology of HF and identifying new potential therapeutic targets.

Heart failure is a common clinical syndrome associated with significant morbidity and mortality worldwide. Ischemic heart disease is the leading cause of heart failure, at least in the industrialized countries. Proper diagnosis of the syndrome and management of patients with heart failure require anatomical and functional information obtained through various imaging modalities. Nuclear cardiology techniques play a main role in the evaluation of heart failure. Myocardial single photon emission computed tomography (SPECT) with thallium-201 or technetium-99 m labelled tracers offer valuable data regarding ventricular function, myocardial perfusion, viability, and intraventricular synchronism. Moreover, positron emission tomography (PET) permits accurate evaluation of myocardial perfusion, metabolism, and viability, providing high-quality images and the ability of quantitative analysis. As these imaging techniques assess different parameters of cardiac structure and function, variations of sensitivity and specificity have been reported among them. In addition, the role of SPECT and PET guided therapy remains controversial. In this comprehensive review, we address these controversies and report the advances in patient's investigation with SPECT and PET in ischemic heart failure. Furthermore, we present the innovations in technology that are expected to strengthen the role of nuclear cardiology modalities in the investigation of heart failure.
Full Text Available Over the past 30 years, the prevalence and incidence of heart failure (HF have increased markedly with age, with increases of approximately fivefold from the age of 40 to 70 years. HF is predominantly a disorder of the elderly, and over 70% of HF patients are over 65 years old. The most important factor in the increasing prevalence and incidence of HF is the growing proportion of elderly with new-onset diastolic HF resulting from chronic hypertension and coronary heart disease. Other predictors of HF include diabetes, prior stroke, atrial fibrillation, renal dysfunction, reduced ankle-brachial index, increased C-reactive protein, left ventricular hypertrophy, reduced forced expiratory volume, and obesity. At least half of all elderly HF patients have preserved left ventricular systolic function, and they are classified as diastolic HF. There was a strong female predominance (67% in diastolic HF when compared with male HF patients. The morbidity and mortality of older HF patients are the highest of any chronic cardiovascular disorder. Mortality increases markedly with age. Mortality from diastolic HF is about half of that reported for systolic HF. There are some comorbidities in older HF patients, including renal dysfunction, chronic lung disease, cognitive dysfunction, depression, postural hypotension, urine incontinence, sensory deprivation, nutritional disorders, polypharmacy and frailty, which may precipitate and exacerbate the underlying HF symptoms. Clinical diagnosis of HF may be more difficult in the elderly because of frequently inadequate history taking, less evident HF symptoms for reduced daily activity, and similar symptoms to other frequent disorders. The treatment goals in older HF patients resemble those for any chronic disorder and include relief of symptoms, improvement in functional status, exercise tolerance, quality of life, prevention of acute exacerbation, and finally, prolongation of long-term survival.

Congestive heart failure may result from cardiovascular overload, from systolic or from diastolic dysfunction. Diastolic left ventricular dysfunction may result from structural resistance to filling such as induced by pericardial constraint, right ventricular compression, increased chamber stiffness
Full Text Available Abstract: Cardiac resynchronization therapy (CRT represents one of the recent advances in heart failure (HF management. It implies an attempt to establish left ventricular synchronous contraction in order to improve left ventricular hemodynamics; thereby improving functional class, and quality of life. CRT has come a long way from an incidental treatment modality to an accepted and indicated treatment strategy for patients suffering from severe and chronic heart failure. With its ever increasing use, it is important that we become conversant with its role in the management of heart failure. This article aims to review the evidence for CRT, how CRT benefits patients of heart failure and reveals the indications of CRT implantation in HF patients.

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.

Flow in the aortic vasculature may impact stroke risk in patients with left ventricular assist devices (LVAD) due to severely altered hemodynamics. Patient-specific 3D models of the aortic arch and great vessels were created with an LVAD outflow graft at 45, 60 and 90° from centerline of the ascending aorta, in order to understand the effect of surgical placement on hemodynamics and thrombotic risk. Intermittent aortic valve opening (once every five cardiac cycles) was simulated and the impact of this residual native output investigated for the potential to wash out stagnant flow in the aortic root region. Unsteady CFD simulations with patient-specific boundary conditions were performed. Particle tracking for 10 cardiac cycles was used to determine platelet residence times and shear stress histories. Thrombosis risk was assessed by a combination of Eulerian and Lagrangian metrics and a newly developed thrombogenic potential metric. Results show a strong influence of LVAD outflow graft angle on hemodynamics in the ascending aorta and consequently on stroke risk, with a highly positive impact of aortic valve opening, even at low frequencies. Optimization of LVAD implantation and management strategies based on patient-specific simulations to minimize stroke risk will be presented
Full Text Available The outcome of patients with chronic heart failure is influencedby the type of coping with chronic heart disease. We employed the COPEquestionnaire to identify the mechanisms of coping and analyze theparameters involved. Our results show that heart failure patients use mainly emotion-based coping (acceptance, seeking emotional support, religion. Independent variables that influence the type of coping mechanisms include gender, anxiety, depression and decreased quality of life. Identification of disadaptive mechanisms should become an important step in a complex management program devised by a multidisciplinary team.

Cardiac performance is normally determined by architectural, cellular, and molecular structures that determine the heart's form, and by physiological and biochemical mechanisms that regulate the function of these structures. Impaired adaptation of form to function in failing hearts contributes to two syndromes initially called systolic heart failure (SHF) and diastolic heart failure (DHF). In SHF, characterized by high end-diastolic volume (EDV), the left ventricle (LV) cannot eject a normal stroke volume (SV); in DHF, with normal or low EDV, the LV cannot accept a normal venous return. These syndromes are now generally defined in terms of ejection fraction (EF): SHF became 'heart failure with reduced ejection fraction' (HFrEF) while DHF became 'heart failure with normal or preserved ejection fraction' (HFnEF or HFpEF). However, EF is a chimeric index because it is the ratio between SV--which measures function, and EDV--which measures form. In SHF the LV dilates when sarcomere addition in series increases cardiac myocyte length, whereas sarcomere addition in parallel can cause concentric hypertrophy in DHF by increasing myocyte thickness. Although dilatation in SHF allows the LV to accept a greater venous return, it increases the energy cost of ejection and initiates a vicious cycle that contributes to progressive dilatation. In contrast, concentric hypertrophy in DHF facilitates ejection but impairs filling and can cause heart muscle to deteriorate. Differences in the molecular signals that initiate dilatation and concentric hypertrophy can explain why many drugs that improve prognosis in SHF have little if any benefit in DHF.

Full Text Available In this article the state of the art of prevalence, incidence and prognosis of heart failure is discussed. Prevalence and incidence are two measures of disease occurrence. Briefly, prevalence is the proportion of the population affected by the disease at a certain point in time. Incidence indicates the number of new cases within a given time period in a population at risk for the disease (for example, elderly people. A related, prognostic measure is mortality, i.e. the incidence of death from the disease occurring in a period of time. In the case of chronic, steady- state disease such as heart failure, disease duration is directly affected by mortality, and prevalence may correspond to the incidence of disease multiplied by the average duration of disease . Prevalence rates of heart failure may, therefore, vary across studies depending on the variability in incidence as well as in survival between population samples. Also, given that heart failure is a complex syndrome with different phenotypes (see article 1, each with specific clinical characteristics and associated risk factors, prevalence and incidence rates may vary according to the definition of the heart failure subtype. Finally, rates may vary on the basis of the method of collecting data and the criterion for defining left ventricular systolic dysfunction that is applied in the study.

The rising prevalence and increasing disease-related costs render chronic heart failure a rapidly growing socioeconomic challenge. The concerted action of guideline-adjusted therapy and holistic patient care is essential to achieve improvements in mortality, morbidity, functional status and quality of life of patients with symptomatic heart failure. Holistic care strategies comprise consideration of comorbidities and individual needs, lifestyle recommendations and multidisciplinary management programs for high-risk symptomatic patients in addition to basic medication and surgical therapies. For optimal patient care and coaching, seamless interaction is required between in-hospital treatment and outpatient facilities. Moreover, the palliative needs of heart failure patients need to be considered, a topic that is currently not receiving enough attention.

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.

This review aims to cover the latest evidence of remote monitoring of cardiac implantable electronic devices for the management of atrial fibrillation and heart failure. Remote monitoring is useful for early detection for device-detected atrial fibrillation, which increases the risk of thromboembolic events. Early anticoagulation based on remote monitoring potentially reduces the risk of stroke, but optimal alert setting needs to be clarified. Multiparameter monitoring with automatic transmission is useful for heart failure management. Improved adherence to remote monitoring and an optimal algorithm for transmitted alerts and their management are warranted in the management of heart failure. Copyright © 2017 Elsevier Inc.

Serum procalcitonin levels are associated with congestive heart failure, but are not established biomarkers of the disease. We evaluated the predictive value of serum procalcitonin levels for diagnosing heart failure and assessing its severity. This retrospective, case-control study involved 59 subjects (mean age 59.7-10.1 years; 38 males), including 21 outpa- tients and 19 inpatients with heart failure and left ventricular ejection fractions procalcitonin levels were measured and compared among the 3 groups. Procalcitonin levels were significantly higher among inpatients (median [interquartile range], 1.45 [0.25-5.801 ng/mL) than among the outpatients (0.35 [0.001.-1.70] ng/mL; Pprocalcitonin cut-off level of 0.09 ng/mL, 35 (87.5%) of the 40 inpatients and outpatients were procalcitonin-positive; all control individuals were procalcitonin-negative. Serum procalcitonin levels differentiated between heart failure patients and healthy controls (sensitivity, 88.9% [95% confidence interval, 75.9-96.2%]; specificity, 100% [82.2-100.0%]; positive predictive value, 100% [91.1-100.0%]; negative predictive value, 79.2% [57.8-92.8%]). Pro calcitonin levels were >0.53 ng/mL in 4/21 (19%) outpatients and in 16/19 (84.2%) inpatients. The sensitivity and specificity of serum procalcitonin levels for differentiating between inpatients and outpatients were 84.2% and 81.0%, respectively (positive predictive value 80% [95% confidence interval, 67.6-92.4%] and 85.0% [73.9-96.1%], respectively). Serum procalcitonin levels, showing high sensitivity and specificity for diagnosing and assessing the severity of heart failure in this small study, might be considered ootential heart failure biomarkers.

Tissue MicroArrays (TMAs) are a versatile tool for high-throughput protein screening, allowing qualitative analysis of a large number of samples on a single slide. We have developed a customizable TMA system that uniquely utilizes cryopreserved human cardiac samples from both heart failure and donor patients to produce formalin-fixed paraffin-embedded sections. Confirmatory upstream or downstream molecular studies can then be performed on the same (biobanked) cryopreserved tissue. In a pilot study, we applied our TMAs to screen for the expression of four-and-a-half LIM-domain 2 (FHL2), a member of the four-and-a-half LIM family. This protein has been implicated in the pathogenesis of heart failure in a variety of animal models. While FHL2 is abundant in the heart, not much is known about its expression in human heart failure. For this purpose, we generated an affinity-purified rabbit polyclonal anti-human FHL2 antibody. Our TMAs allowed high-throughput profiling of FHL2 protein using qualitative and semiquantitative immunohistochemistry that proved complementary to Western blot analysis. We demonstrated a significant relative reduction in FHL2 protein expression across different forms of human heart failure. © 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Research findings on the value of nurse certification were based on subjective perceptions or biased by correlations of certification status and global clinical factors. In heart failure, the value of certification is unknown. Examine the value of certification based nurses' decision-making. Cross-sectional study of nurses who completed heart failure clinical vignettes that reflected decision-making in clinical heart failure scenarios. Statistical tests included multivariable linear, logistic and proportional odds logistic regression models. Of nurses (N = 605), 29.1% were heart failure certified, 35.0% were certified in another specialty/job role and 35.9% were not certified. In multivariable modeling, nurses certified in heart failure (versus not heart failure certified) had higher clinical vignette scores (p = 0.002), reflecting higher evidence-based decision making; nurses with another specialty/role certification (versus no certification) did not (p = 0.62). Heart failure certification, but not in other specialty/job roles was associated with decisions that reflected delivery of high-quality care. Copyright © 2018 Elsevier Inc. All rights reserved.

Summary: Chronic cardiovascular disease imposes a significant health and economic burden on individuals and communities. Despite decades of improvement in cardiovascular mortality, cardiovascular disease and stroke remain the leading cause of death in the U.S. and disparities in health outcomes persist. Moreover, the continuous improvement in cardiovascular mortality typical of the last four decades has ended motivating new and innovative approaches to improve population health and wellbeing. Apart from continued focus on traditional risk factor modification such as identification and treatment of high blood pressure and cholesterol, cessation of smoking, and appropriate use of evidence-based pharmacological prevention measures and disease management, other factors should be considered such as increasing physical activity, dietary sodium reduction and modification of social and environmental determinants known to cause heart attacks and stroke and exacerbate vascular disease. Such an approach will require greater cooperation among public health, environmental health, the broader public and private healthcare delivery and payment systems, and federal agencies. To introduce this concept the U.S. EPA held a workshop in September 2016 bringing together representatives of local and state public health officials, the healthcare system, educators, data analytics, and federal partners (CMS, CDC, Dept. of State and EPA) for the purpose of exploring the idea of prom

Less intensive treatment for heart failure with reduced ejection fraction (HFrEF) may be appropriate for patients in long-term care settings because of limited life expectancy, frailty, comorbidities, and emphasis on quality of life. We compared treatment patterns between REasons for Geographic And Racial Differences in Stroke (REGARDS) study participants discharged to long-term care versus home following HFrEF hospitalizations. We examined medical records and Medicare pharmacy claims for 147 HFrEF hospitalizations among 80 participants to obtain information about discharge disposition and medication prescriptions and fills. Discharge to long-term care followed 22 of 147 HFrEF hospitalizations (15%). Participants discharged to long-term care were more likely to be prescribed beta-blockers and less likely to be prescribed aldosterone receptor antagonists and hydralazine/isosorbide dinitrate (96%, 14%, and 5%, respectively) compared to participants discharged home (81%, 22%, and 23%, respectively). The percentages of participants discharged to long-term care and home who had claims for filled prescriptions were similar for beta-blockers (68% versus 66%) and angiotensin converting enzyme inhibitors or angiotensin receptor blockers (ACEI/ARBs) (45% versus 47%) after 1 year. Smaller percentages of participants discharged to long-term care had claims for filled prescriptions of other medications compared to participants discharged home (diuretics: long-term care-50%, home-72%; hydralazine/isosorbide dinitrate: long-term care-5%, home-23%; aldosterone receptor antagonists: long-term care-5%, home-23%). Differences in medication prescriptions and fills among individuals with HFrEF discharged to long-term care versus home may reflect prioritization of some medical therapies over others for patients in long-term care.

Ischaemic heart disease and stroke are vascular events with serious health consequences worldwide. Recent genetic and epigenetic techniques have revealed many genetic determinants of these vascular events and simplified the approaches to research focused on ischaemic heart disease and stroke. The pathogenetic mechanisms of ischaemic heart disease and stroke are complex, with mitochondrial involvement (partially or entirely) recently gaining substantial support. Not only can mitochondrial reactive oxygen species give rise to ischaemic heart disease and stroke by production of oxidised low-density lipoprotein and induction of apoptosis, but the impact on pericytes contributes directly to the pathogenesis. Over the past two decades, publications implicate the causative role of nuclear genes in the development of ischaemic heart disease and stroke, in contrast to the potential role of mitochondrial DNA (mtDNA) in the pathophysiology of the disorders, which is much less understood, although recent studies do demonstrate that the involvement of mitochondria and mtDNA in the development of ischaemic heart disease and stroke is likely to be larger than originally thought, with the novel discovery of links among mitochondria, mtDNA and vascular events. Here we explore the molecular events and mtDNA alterations in relation to the role of mitochondria in ischaemic heart disease and stroke.

Acute heart failure is a major and growing public health problem worldwide with high morbidity, mortality, and cost. Despite recent advances in pharmacological management, the prognosis of patients with acute decompensated heart failure remains poor. Consequently, nonpharmacological approaches are being developed and increasingly used. Such techniques may include several modalities of ventilation, ultrafiltration, mechanical circulatory support, myocardial revascularization, and surgical treatment, among others.

To evaluate effectiveness of nonpeptide angiotensin-2 subtype-1 receptor antagonist losartan in therapy of symptomatic congestive heart failure in patients with ischemic heart disease, 116 patients were examined at the age of 36-62 (mean age 50.6 +/- 4.22). They had angina pectoris of functional class II-III (according to CCS) and congestive heart failure of functional class II-III (according to NYHA). All the patients were randomized into two groups. 60 patients of group 1 received basic medication with nitrates, diuretic (on demand), digoxin and aspirin. 56 patients of group 2 received basic medication and losartan (cozaar, MSD, USA) in the dose 25 mg/day for 48 weeks. Echocardiographic monitoring of the treatment efficacy was made. The outcomes of the treatment evidence that losartan improves the patients' clinical status and heart failure functional class. For twelve weeks losartan reduced left ventricular and atrial dilation positively influencing the isometric inotropic indices. In 48 weeks losartan arrested progression of pathologic remodelling of the left ventricle and prevents depression of total myocardial contractility. Losartan's positive effect in restriction of negative evolution of cardiac failure manifests on the treatment week 3.

The purpose of this study was to gain a better understanding of the process of becoming a patient with heart failure, a process of identity formation. Are there clues in the patients' stories about heart failure that might give us a better idea of how patients adjust to heart failure and what heart failure means to them? Meanings that individuals attach to events or situations are central to development of identity and subsequent behaviors. Qualitative methods involving detailed interviews and grounded theory method were used in an outpatient cardiology department of a large health care facility in northeast Ohio. Twenty-one patients with a diagnosis of heart failure were conveniently selected and interviewed for this research. Patients were selected on the basis of having a left ventricular ejection fraction of 35% or less and New York Heart Association class II, III, or IV. Other possible selection criteria (eg, VO(2Max ), walk test, or dyspnea) were not available for all patients and thus did not constitute consistent selection criteria. A broad net was cast for patients with varying characteristics to see if common processes and experiences existed regardless of the differences in clinical indicators. Patients were interviewed in the examining room as part of a regularly scheduled visit with their cardiologists. All interviews were tape recorded and fully transcribed. Field notes and relevant patient chart data (eg, age, sex, race, marital status, cause of heart failure, comorbidities, history of hospitalization, New York Heart Association functional class, left ventricular ejection fraction) were included in the transcribed interviews. The transcribed interview was read and responses were given initial conceptual codes. These coded passages were categorized according to more abstract categories or concepts and underlying processes that encompass them. This process continues until all relevant passages have been categorized and subsumed under higher-order (more

Adults with congenital heart disease represent a rapidly growing patient group. Dysfunction of the right ventricle is often present, and right heart failure constitutes the main cause of death. Heart failure therapies used in acquired left heart failure are often initiated in adults with right heart failure due to congenital heart disease, but the right ventricle differs substantially from the left ventricle, and the clinical evidence for this treatment strategy is lacking. In this review,...

Dialysis in patients with severe congestive heart failure and low blood pressure is difficult even in a hospital setting. We retrospectively recorded the effects and usefulness of an alpha (1) agonist in an outpatient dialysis unit in 5 patients with end-stage renal disease with symptomatic heart failure and low blood pressure. To provide outpatient dialysis, they were given midodrine before and during their dialysis sessions. The volume of fluid removed, the lowest blood pressure, and postdialysis blood pressure measurements were recorded during a 3- to 4-week period just before initiating therapy (control period) and were compared with the measurements while using midodrine (treatment period). The blood pressures were expressed as the average of the mean arterial pressures (MAP). All patients had an increase in the lowest MAP during dialysis and in the postdialysis MAP. Each was significant at P = 0.03. Fluid removal was significant at P = 0.04. All the patients improved in their symptoms of orthopnea and shortness of breath. Outpatient dialysis is possible and relieves the symptoms of congestive heart failure in patients with poor heart function, low blood pressure, and advanced age when midodrine is given immediately before and during the procedure.

Nuclear cardiology is the most commonly performed non-invasive cardiac imaging test in patients with heart failure, and it plays an important role in their assessment and management. Quantitative gated single positron emission computed tomography is used to assess quantitatively cardiac volume, left ventricular ejection fraction, stroke volume, and cardiac diastolic function. Resting and stress myocardial perfusion imaging can not only identify nonischemic heart failure and ischemic heart failure, but also demonstrate myocardial viability. Diastolic heart failure also termed as heart failure with a preserved left ventricular ejection fraction is readily identified by nuclear cardiology techniques and can accurately be estimated by peak filling rate and time to peak filling rate. With newer techniques such as three-dimensional, quantitative gated single positron emission computed tomography can assess movement of the left ventricle, and wall thickening evaluation aids its assessment. Myocardial perfusion imaging is also commonly used to identify candidates for implantable cardiac defibrillator and cardiac resynchronization therapies. Neurotransmitter imaging using 123 I-metaiodobenzylguanidine offers prognostic information in patients with heart failure. Metabolism and function in the heart are closely related, and energy substrate metabolism is a potential target of medical therapies to improve cardiac function in patients with heart failure. Cardiac metabolic imaging using 123 I-15-(p-iodophenyl) 3-R, S-methylpentadecacoic acid is a commonly used tracer in clinical studies to diagnose metabolic heart failure. Nuclear cardiology tests, including neurotransmitter imaging and metabolic imaging, are now easily preformed with new tracers to improve heart failure diagnosis. Nuclear cardiology techniques contribute significantly to identifying patients with heart failure and to guiding their management decisions. (authors)

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.

Heart failure is a global problem. It is estimated that approximately 38 million people worldwide experience heart failure, and this number is growing because of the ageing of nations' populations, but also because patients are rescued from death during an acute myocardial infarction, and later develop heart failure.

Full Text Available Heart failure (HF is a complex clinical syndrome that results from any structural or functional impairment of ventricular filling or ejection of blood. HF is one of the most important and severe end stages of many cardiovascular diseases. Epidemiological studies of HF have focused mainly on the prevalence, incidence, mortality, fatality, and distribution and temporal trends of these indicators among different populations. This review highlights important epidemiological studies of HF in China.

Elevated heart rate (HR) is associated with worse outcomes in patients with cardiovascular disease. Its predictive value in acute stroke patients is less well established. We investigated the effects of HR on admission in acute ischaemic stroke patients. Using the Virtual International Stroke Trials Archive (VISTA) database, the association between HR in acute stroke patients without atrial fibrillation and the pre-defined composite end-point of (recurrent) ischaemic stroke, transient ischaemic attack (TIA), myocardial infarction (MI) and vascular death within 90 days was analysed. Pre-defined secondary outcomes were the composite end-point components and any death, decompensated heart failure and degree of functional dependence according to the modified Rankin Scale after 90 days. HR was analysed as a categorical variable (quartiles). In all, 5606 patients were available for analysis (mean National Institutes of Health Stroke Scale 13; mean age 67 years; mean HR 77 bpm; 44% female) amongst whom the composite end-point occurred in 620 patients (11.1%). Higher HR was not associated with the composite end-point. The frequencies of secondary outcomes were 3.2% recurrent stroke (n = 179), 0.6% TIA (n = 35), 1.8% MI (n = 100), 6.8% vascular death (n = 384), 15.0% any death (n = 841) and 2.2% decompensated heart failure (n = 124). Patients in the highest quartile (HR> 86 bpm) were at increased risk for any death [adjusted hazard ratio (95% confidence interval) 1.40 (1.11-1.75)], decompensated heart failure [adjusted hazard ratio 2.20 (1.11-4.37)] and worse modified Rankin Scale [adjusted odds ratio 1.29 (1.14-1.52)]. In acute stroke patients, higher HR (>86 bpm) is linked to mortality, heart failure and higher degree of dependence after 90 days but not to recurrent stroke, TIA or MI. © 2016 EAN.

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.

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

Often ignored, neurocognitive dysfunction in chronic heart failure represents a daunting morbidity progressing to loss of self-reliance. Although the precise mechanisms arbitrating the development of this disorder remain elusive, microembolization and cerebral hypoperfusion are implicated. Other causes of cognitive decline may include prior cardiac surgery, chronic hypertension, sleep disordered breathing, hyperhomocysteinemia, dementia of aging, and more traditional causes such as Alzheimer's disease. The discovery of neurocognitive defects in heart failure must prompt a well-constructed diagnostic evaluation to search for the underlying causes since this process may be at least partially reversible in many cases.

Acute heart failure describes the rapid deterioration, over minutes, days or hours, of symptoms and signs of heart failure. Its management is an interdisciplinary challenge that requires the cooperation of various specialists. While emergency providers, (interventional) cardiologists, heart surgeons, and intensive care specialists collaborate in the initial stabilization of acute heart failure patients, the involvement of nurses, discharge managers, and general practitioners in the heart failure team may facilitate the transition from inpatient care to the outpatient setting and improve acute heart failure readmission rates. This review highlights the importance of a multidisciplinary approach to acute heart failure with particular focus on the chain-of-care delivered by the various services within the healthcare system.

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.

Patients with congenital heart disease (CHD) may be at increased risk of ischemic stroke due to residual shunts, arrhythmias, and other cardiovascular abnormalities. We studied the relative risk and potential factors for developing ischemic stroke in children and young adults with CHD in Sweden. All patients in the Swedish Patient Register with a diagnosis of CHD, born between 1970 and 1993, were identified and compared with 10 controls for each patient, matched for age, sex, and county and randomly selected from the general population. Follow-up data through 2011 were collected for both groups. Of 25 985 children and young adults with CHD (51.5% male, 48.5% female), 140 (0.5%) developed ischemic stroke. The hazard ratio for CHD patients developing ischemic stroke was 10.8 (95% CI, 8.5-13.6) versus controls. All major Marelli groups had significantly increased risk, but because of small CHD-group sizes, only atrial septal defect/patent foramen ovale, double-inlet ventricle, and aortic coarctation displayed significantly increased risk. In multivariate analysis of CHD patients, congestive heart failure carried the highest risk for developing ischemic stroke (hazard ratio 6.9 [95% CI, 4.7-10.3]), followed by hypertension and atrial fibrillation, which were also significantly associated with increased risk of ischemic stroke. The risk of developing ischemic stroke was almost 11 times higher in young patients with CHD than in the general population, although absolute risk is low. Cardiovascular comorbidities were strongly associated with the development of ischemic stroke in young CHD patients. © 2016 The Authors.

Full Text Available IntroductionHeart failure is a major cardiovascular health problem. Coronary artery disease is the leading cause of congestive heart failure (CHF . Cardiac transplantation remains the most effective long-term treatment option, however is limited primarily by donor availability, rejection and infections. Mechanical circulatory support has its own indications and limitations . Therefore, there is a need to develop more effective therapeutic strategies.Recently, regenerative medicine has received considerable scientific attention in the cardiovascular arena. We report here our experience demonstrating the beneficial effects of cardiac stem cell therapy on left ventricular functions in a patient with Hodgkin’s lymphoma (HL who developed CHF due to ischemic heart disease during the course of lymphoma treatment. Case reportA 58-year-old male with relapsed HL was referred to our bone marrow transplantation unit in October 2009. He was given 8 courses of combination chemotherapy with doxorubicin, bleomycin, vincristine, and dacarbazine (ABVD between June 2008 and February 2009 and achieved complete remission. However, his disease relapsed 3 months after completing the last cycle of ABVD and he was decided to be treated with DHAP (cisplatin, cytarabine, dexamethasone followed autologous stem cell transplantation (SCT. After the completion of first course of DHAP regimen, he developed acute myocardial infarction (AMI and coronary artery bypass grafting (CABG was performed. After his cardiac function stabilized, 3 additional courses of DHAP were given and he was referred to our centre for consideration of autologous SCT. Computed tomography scans obtained after chemotherapy confirmed complete remission. Stem cells were collected from peripheral blood after mobilization with 10 µg/kg/day granulocyte colony-stimulating factor (G-CSF subcutaneously. Collection was started on the fifth day of G-CSF and performed for 3 consecutive days. Flow cytometric

This review explores key features and potential management controversies in two emerging populations in heart failure: heart failure with recovered ejection fraction (HF-recovered EF) and heart failure with mid-range ejection fraction (HFmrEF). While HF-recovered EF patients have better outcomes than heart failure with reduced ejection fraction (HFrEF), they continue to have symptoms, persistent biomarker elevations, and abnormal outcomes suggesting a continued disease process. HFmrEF patients appear to have features of HFrEF and heart failure with preserved ejection fraction (HFpEF), but have a high prevalence of ischemic heart disease and may represent a transitory phase between the HFrEF and HFpEF. Management strategies have insufficient data to warrant standardization at this time. HF-recovered EF and HFmrEF represent new populations with unmet needs and expose the pitfalls of an EF basis for heart failure classification.

With a prevalence of 5.8 million in the United States alone, heart failure (HF) is associated with high morbidity, mortality, and healthcare expenditures. Close to 1 million hospitalizations for heart failure (HHF) occur annually, accounting for over 6.5 million hospital days and a substantial portion of the estimated $37.2 billion that is spent each year on HF in the United States. Although some progress has been made in reducing mortality in patients hospitalized with HF, rates of rehospitalization continue to rise, and approach 30% within 60 to 90 days of discharge. Approximately half of HHF patients have preserved or relatively preserved ejection fraction (EF). Their post-discharge event rate is similar to those with reduced EF. HF readmission is increasingly being used as a quality metric, a basis for hospital reimbursement, and an outcome measure in HF clinical trials. In order to effectively prevent HF readmissions and improve overall outcomes, it is important to have a complete and longitudinal characterization of HHF patients. This paper highlights management strategies that when properly implemented may help reduce HF rehospitalizations and include adopting a mechanistic approach to cardiac abnormalities, treating noncardiac comorbidities, increasing utilization of evidence-based therapies, and improving care transitions, monitoring, and disease management.

Mediators from peripheral tissues can influence the development and progression of heart failure (HF). For example, in obesity, an altered profile of adipokines secreted from adipose tissue increases the incidence of myocardial infarction (MI). Less appreciated is that heart remodeling releases cardiokines, which can strongly impact various peripheral tissues. Inflammation, and, in particular, activation of the nucleotide-binding oligomerization domain-like receptors with pyrin domain (NLRP3) inflammasome are likely to have a central role in cardiac remodeling and mediating crosstalk with other organs. Activation of the NLRP3 inflammasome in response to cardiac injury induces the production and secretion of the inflammatory cytokines interleukin (IL)-1β and IL-18. In addition to having local effects in the myocardium, these pro-inflammatory cytokines are released into circulation and cause remodeling in the spleen, kidney, skeletal muscle and adipose tissue. The collective effects of various cardiokines on peripheral organs depend on the degree and duration of myocardial injury, with systematic inflammation and peripheral tissue damage observed as HF progresses. In this article, we review mechanisms regulating myocardial inflammation in HF and the role of factors secreted by the heart in communication with peripheral tissues.
Full Text Available Recent reports suggest that 20 million people worldwide are regularly using khat as a stimulant, even though the habit of chewing khat is known to cause serious health issues. Historical evidence suggests khat use has existed since the 13th century in Ethiopia and the southwestern Arabian regions even before the cultivation and use of coffee. In the past three decades, its availability and use spread all over the world including the United States and Europe. Most of the consumers in the Western world are immigrant groups from Eastern Africa or the Middle East. The global transport and availability of khat has been enhanced by the development of synthetic forms of its active component. The World Health Organization considers khat a drug of abuse since it causes a range of health problems. However, it remains lawful in some countries. Khat use has long been a part of Yemeni culture and is used in virtually every social occasion. The main component of khat is cathinone, which is structurally and functionally similar to amphetamine and cocaine. Several studies have demonstrated that khat chewing has unfavorable cardiovascular effects. The effect on the myocardium could be explained by its effect on the heart rate, blood pressure, its vasomotor effect on the coronary vessels, and its amphetamine–like effects. However, its direct effect on the myocardium needs further elaboration. To date, there are few articles that contribute death among khat chewers to khat-induced heart failure. Further studies are needed to address the risk factors in khat chewers that may explain khat-induced cardiotoxicity, cardiomyopathy, and heart failure.

This article presents the most relevant developments in 2013 in 3 key areas of cardiology: congenital heart disease, clinical cardiology, and heart failure and transplant. Within the area of congenital heart disease, we reviewed contributions related to sudden death in adult congenital heart disease, the importance of specific echocardiographic parameters in assessing the systemic right ventricle, problems in patients with repaired tetralogy of Fallot and indication for pulmonary valve replacement, and confirmation of the role of specific factors in the selection of candidates for Fontan surgery. The most recent publications in clinical cardiology include a study by a European working group on correct diagnostic work-up in cardiomyopathies, studies on the cost-effectiveness of percutaneous aortic valve implantation, a consensus document on the management of type B aortic dissection, and guidelines on aortic valve and ascending aortic disease. The most noteworthy developments in heart failure and transplantation include new American guidelines on heart failure, therapeutic advances in acute heart failure (serelaxin), the management of comorbidities such as iron deficiency, risk assessment using new biomarkers, and advances in ventricular assist devices.

This paper reviews treatment options for sleep disordered breathing (SDB) in patients with heart failure. We sought to identify therapies for SDB with the best evidence for long-term use in patients with heart failure and to minimize uncertainties in clinical practice by examining frequently discussed questions: what is the role of continuous positive airway pressure (CPAP) in patients with heart failure? Is adaptive servo-ventilation (ASV) safe in patients with heart failure? To what extent is SDB a modifiable risk factor? Consistent evidence has demonstrated that the development of SDB in patients with heart failure is a poor prognostic indicator and a risk factor for cardiovascular mortality. However, despite numerous available interventions for obstructive sleep apnea and central sleep apnea, it remains unclear what effect these therapies have on patients with heart failure. To date, all major randomized clinical trials have failed to demonstrate a survival benefit with SDB therapy and one major study investigating the use of adaptive servo-ventilation demonstrated harm. Significant questions persist regarding the management of SDB in patients with heart failure. Until appropriately powered trials identify a treatment modality that increases cardiovascular survival in patients with SDB and heart failure, a patient's heart failure management should remain the priority of medical care.

Despite therapeutic advances, patients with worsening heart failure (HF) requiring hospitalization have unacceptably high post-discharge mortality and re-admission rates soon after discharge. Evidence suggests a hypercoagulable state is present in patients with HF. Although thromboembolism as a direct consequence of HF is not frequently clinically recognized, it may contribute to mortality and morbidity. Additionally, many patients with HF have concomitant disorders conferring additional thrombotic risk, including atrial fibrillation (AF) and coronary artery disease (CAD). Acute coronary syndrome (ACS), a known consequence of coronary thrombosis, is a common precipitating factor for worsening HF. Coronary thrombosis may also cause sudden death in patients with HF and CAD. Because data are largely derived from observational studies or trials of modest size, guideline recommendations on anticoagulation for HF vary between organizations. The recently presented Warfarin versus Aspirin in Reduced Cardiac Ejection Fraction trial of HF patients in sinus rhythm suggested anticoagulation reduces the risk of stroke, although rates of the combined primary endpoint (death, ischemic stroke, or intracerebral hemorrhage) were similar for acetylsalicylic acid and warfarin. Newer oral anticoagulants dabigatran, apixaban, and rivaroxaban have successfully completed trials for the prevention of stroke in patients with AF and have shown benefits in the subpopulation of patients with concomitant HF. Positive results of the Anti-Xa Therapy to Lower Cardiovascular Events in Addition to Standard Therapy in Subjects with Acute Coronary Syndrome-Thrombolysis in Myocardial Infarction 51 (ATLAS ACS 2-TIMI 51) trial of rivaroxaban in ACS are also encouraging. These data suggest there is a need to assess the potential role for these newer agents in the management of patients hospitalized for HF who continue to have a high post-discharge event rate despite available therapies.

Given its prevalence, high mortality rate, morbidity, chronicity and use of resources, heart failure (HF) is a priority issue from a social and health standpoint, due to the ageing population and to lack of adherence to and the complexity of treatment. For these reasons, an individualized care plan needs to be established to meet the real and potential needs of the patient diagnosed with HF. A clinical case is presented of a patient admitted to the Cardiology Critical Care (CCC) unit of a tertiary hospital. A patient care plan was prepared following the steps of the scientiﬁc method and relying on the NANDA taxonomy, and the NOC and NIC to design goals and nursing interventions, respectively.

Unlike chronic heart failure (HF), the treatment for acute HF has not changed over the last decade. The drugs employed have shown their ability to control symptoms but have not achieved organ protection or managed to reduce medium to long-term morbidity and mortality. Advances in our understanding of the pathophysiology of acute HF suggest that treatment should be directed not only towards correcting the haemodynamic disorders and achieving symptomatic relief but also towards preventing organ damage, thereby counteracting myocardial remodelling and cardiac and extracardiac disorders. Compounds that exert vasodilatory and anti-inflammatory action in the acute phase of HF and can stop cell death, thereby boosting repair mechanisms, could have an essential role in organ protection.

Congestive heart failure (CHF) is a chronic and often devastating cardiovascular disorder with no cure. There has been much advancement in the last two decades that has seen improvements in morbidity and mortality. Clinicians have also noted variations in the responses to therapies. More detailed observations also point to clusters of diseases, phenotypic groupings, unusual severity and the rates at which CHF occurs. Medical genetics is playing an increasingly important role in answering some of these observations. This developing field in many respects provides more information than is currently clinically applicable. This includes making sense of the established single gene mutations or uncommon private mutations. In this thematic series which discusses the many factors that could be relevant for CHF care, once established treatments are available in the communities; this section addresses a contextual role for medical genetics.

The molecular pathophysiology of heart failure, which is one of the leading causes of mortality, is not yet fully understood. Heart failure can be regarded as a systemic syndrome of aging-related phenotypes. Wnt/β-catenin signaling and the p53 pathway, both of which are key regulators of aging, have been demonstrated to play a critical role in the pathogenesis of heart failure. Circulating C1q was identified as a novel activator of Wnt/β-catenin signaling, promoting systemic aging-related phenotypes including sarcopenia and heart failure. On the other hand, p53 induces the apoptosis of cardiomyocytes in the failing heart. In these molecular mechanisms, the cross-talk between cardiomyocytes and non-cardiomyocytes (e,g,. endothelial cells, fibroblasts, smooth muscle cells, macrophages) deserves mentioning. In this review, we summarize recent advances in the understanding of the molecular pathophysiology underlying heart failure, focusing on Wnt/β-catenin signaling and the p53 pathway.

Full Text Available OBJECTIVE: To report the hemodynamic and functional responses obtained with clinical optimization guided by hemodynamic parameters in patients with severe and refractory heart failure. METHODS: Invasive hemodynamic monitoring using right heart catheterization aimed to reach low filling pressures and peripheral resistance. Frequent adjustments of intravenous diuretics and vasodilators were performed according to the hemodynamic measurements. RESULTS: We assessed 19 patients (age = 48±12 years and ejection fraction = 21±5% with severe heart failure. The intravenous use of diuretics and vasodilators reduced by 12 mm Hg (relative reduction of 43% pulmonary artery occlusion pressure (P<0.001, with a concomitant increment of 6 mL per beat in stroke volume (relative increment of 24%, P<0.001. We observed significant associations between pulmonary artery occlusion pressure and mean pulmonary artery pressure (r=0.76; P<0.001 and central venous pressure (r=0.63; P<0.001. After clinical optimization, improvement in functional class occurred (P< 0.001, with a tendency towards improvement in ejection fraction and no impairment to renal function. CONCLUSION: Optimization guided by hemodynamic parameters in patients with refractory heart failure provides a significant improvement in the hemodynamic profile with concomitant improvement in functional class. This study emphasizes that adjustments in blood volume result in imme-diate benefits for patients with severe heart failure.

Heart failure (HF) is a leading cause of morbidity and mortality in patients with chronic kidney disease (CKD), and the population of CKD patients with concurrent HF continues to grow. The accurate diagnosis of HF is challenging in patients with CKD in part due to a lack of validated imaging and biomarkers specifically in this population. The pathophysiology between the heart and the kidneys is complex and bidirectional. Patients with CKD have greater prevalence of traditional HF risk factors as well as unique kidney-specific risk factors including malnutrition, acid-base alterations, uraemic toxins, bone mineral changes, anemia and myocardial stunning. These risk factors also contribute to the decline of kidney function seen in patients with subclinical and clinical HF. More targeted HF therapies may improve outcomes in patients with kidney disease as current HF therapies are underutilised in this population. Further work is also needed to develop novel HF therapies for the CKD population. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Patients with chronic heart failure (HF) are limited in their quality of life, have a poor prognosis and face frequent hospitalisations. Patient self-management was shown to improve quality of life, reduce rehospitalisations and costs in patients with chronic HF. Comprehensive disease management programmes are critical to foster patient self-management. The chronic care model developed by the WHO serves as the basis of such programmes. In order to develop self-management skills a needs orientated training concept is mandatory, as patients need both knowledge of the illness and the ability to use the information to make appropriate decisions according to their individual situation. Switzerland has no established system for the care of patients with chronic diseases in particular those with HF. For this reason a group of Swiss experts for HF designed a model for disease management for HF patients in Switzerland. Since 2009 the Swiss Heart Foundation offers an education programme based on this model. The aim of this programme is to offer education and support for practitioners, patients and families. An initial pilot evaluation of the program showed mixed acceptance by practitioners, whereas patient assessed the program as supportive and in line with their requirements.

Full Text Available Abstract Our aim is to summarize and discuss the recent literature linking diabetes mellitus with heart failure, and to address the issue of the optimal treatment for diabetic patients with heart failure. The studies linking diabetes mellitus (DM with heart failure (HF The prevalence of diabetes mellitus in heart failure populations is close to 20% compared with 4 to 6% in control populations. Epidemiological studies have demonstrated an increased risk of heart failure in diabetics; moreover, in diabetic populations, poor glycemic control has been associated with an increased risk of heart failure. Various mechanisms may link diabetes mellitus to heart failure: firstly, associated comorbidities such as hypertension may play a role; secondly, diabetes accelerates the development of coronary atherosclerosis; thirdly, experimental and clinical studies support the existence of a specific diabetic cardiomyopathy related to microangiopathy, metabolic factors or myocardial fibrosis. Subgroup analyses of randomized trials demonstrate that diabetes is also an important prognostic factor in heart failure. In addition, it has been suggested that the deleterious impact of diabetes may be especially marked in patients with ischemic cardiomyopathy. Treatment of heart failure in diabetic patients The knowledge of the diabetic status may help to define the optimal therapeutic strategy for heart failure patients. Cornerstone treatments such as ACE inhibitors or beta-blockers appear to be uniformly beneficial in diabetic and non diabetic populations. However, in ischemic cardiomyopathy, the choice of the revascularization technique may differ according to diabetic status. Finally, clinical studies are needed to determine whether improved metabolic control might favorably influence the outcome of diabetic heart failure patients.

The interaction of influenza infection with the pathogenesis of acute heart failure (AHF) and the worsening of chronic heart failure (CHF) is rather complex. The deleterious effects of influenza infection on AHF/CHF can be attenuated by specific immunization. Our review aimed to summarize the efficacy, effectiveness, safety, and dosage of anti-influenza vaccination in HF. In this literature review, we searched MEDLINE and EMBASE from January 1st 1966 to December 31st, 2016, for studies examining the association between AHF/CHF, influenza infections, and anti-influenza immunizations. We used broad criteria to increase the sensitivity of the search. HF was a prerequisite for our search. The search fields used included "heart failure," "vaccination," "influenza," "immunization" along with variants of these terms. No restrictions on the type of study design were applied. The most common clinical scenario is exacerbation of pre-existing CHF by influenza infection. Scarce evidence supports a potential positive association of influenza infection with AHF. Vaccinated patients with pre-existing CHF have reduced all-cause morbidity and mortality, but effects are not consistently documented. Immunization with higher antigen quantity may confer additional protection, but such aggressive approach has not been generally advocated. Further studies are needed to delineate the role of influenza infection on AHF/CHF pathogenesis and maintenance. Annual anti-influenza vaccination appears to be an effective measure for secondary prevention in HF. Better immunization strategies and more efficacious vaccines are urgently necessary.

The FINRISK risk calculator predicts 10-year risk for coronary heart disease, stroke incidence, and their combination. The model is based on 10-year cohort follow-up from 3 different cohorts in 1982, 1987, and 1992 from a random population sample in 3 areas in Finland. Coronary heart disease, stroke, and their combination are predicted by smoking, systolic blood pressure, total cholesterol, high-density lipoprotein cholesterol, diabetes, and family history. The Internet-based calculator is commonly used in Finland in health services to assess the need for hypertension and hypercholesterolemia treatment and is used also in patients' counseling.

Heart failure is a leading cause of death and the development of effective and safe therapeutic agents for heart failure has been proven challenging. In this study, taking advantage of larval zebrafish, we developed a zebrafish heart failure model for drug screening and efficacy assessment. Zebrafish at 2 dpf (days postfertilization) were treated with verapamil at a concentration of 200 μM for 30 min, which were determined as optimum conditions for model development. Tested drugs were administered into zebrafish either by direct soaking or circulation microinjection. After treatment, zebrafish were randomly selected and subjected to either visual observation and image acquisition or record videos under a Zebralab Blood Flow System. The therapeutic effects of drugs on zebrafish heart failure were quantified by calculating the efficiency of heart dilatation, venous congestion, cardiac output, and blood flow dynamics. All 8 human heart failure therapeutic drugs (LCZ696, digoxin, irbesartan, metoprolol, qiliqiangxin capsule, enalapril, shenmai injection, and hydrochlorothiazide) showed significant preventive and therapeutic effects on zebrafish heart failure (p failure model developed and validated in this study could be used for in vivo heart failure studies and for rapid screening and efficacy assessment of preventive and therapeutic drugs.

The number of studies demonstrating the importance of right ventricular remodelling in a wide range of cardiovascular diseases has increased in the past two decades. Speckle-tracking imaging provides new variables that give comprehensive information about right ventricular function and mechanics. In this review, we summarize current knowledge of right ventricular mechanics in heart failure with reduced ejection fraction and preserved ejection fraction. We searched PubMed, MEDLINE, Ovid and Embase databases for studies published from January 2000 to December 2016 in the English language using the following keywords: "right ventricle"; "strain"; "speckle tracking"; "heart failure with reduced ejection fraction"; and "heart failure with preserved ejection fraction". Investigations showed that right ventricular dysfunction is associated with higher cardiovascular and overall mortality in patients with heart failure, irrespective of ejection fraction. The number of studies investigating right ventricular strain in patients with heart failure with reduced ejection fraction is constantly increasing, whereas data on right ventricular mechanics in patients with heart failure with preserved ejection fraction are limited. Given the high feasibility, accuracy and clinical implications of right ventricular strain in the population with heart failure, it is of great importance to try to include the evaluation of right ventricular strain as a regular part of each echocardiographic examination in patients with heart failure. However, further investigations are necessary to establish right ventricular strain as a standard variable for decision-making. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

Full Text Available Congestive heart failure is consistently associated with adverse outcomes, and is characterized by a twofold increase in mortality in noncardiac surgery. In this regard, developing the methods aimed to prevent and treatacute heart failure (AHF in the intraoperative period remain a challenging problem.Objective. To evaluate the efficacy of preoperative levosimendan infusion in reduction both mortality and duration of treatment of elderly patients with reduced left ventricular ejection fraction in noncardiac surgery.Material and Methods. Design: Multicenter blind randomized placebocontrolled study. Patients: 81 patients operated on abdominal organs. The main endpoint of the study: The length of stay in the Intensive Care Unit (ICU and at the hospital were chosen as the primary endpoints. The secondary endpoints of the study were 30 day and annual mortality, the rate of acute myocardial infarction and stroke.Results. Levosimendan infusion at a rate of 0,05 μg/kg/min — 0,1 μg/kg/min to patients with low left ven tricular ejection fraction just before the surgery reduced the length of stay in ICU for 2 days and required hospital stay for 3 days. NTproBNP showed the best ratio of sensitivity/specificity in predicting 30day mortality in cumulative group: AUC=0,86 (90,77 to 0,93, P<0,0001. From other indicators the most informative were the Inotropes scoring, no change or decrease of a left ventricular ejection fraction, and cardiac index.Conclusion. To reduce perioperative mortality, the intravenous infusion of levosimendan at a rate of 0,05—0,1 μg/kg/min in elderly patients with low left ventricular ejection fraction is recommened as a preoperative preparation the day before the alleged noncardiac surgery.

Heart failure is a relatively common disorder associated with high morbidity, mortality, and economic burden. Better tools to predict outcomes for patients with heart failure could allow for better decision making concerning patient treatment and management and better utilization of health care resources. Endomyocardial biopsy offers a mechanism to pathologically diagnose specific diseases in patients with heart failure, but such biopsies can often be negative, with no specific diagnostic information. Novel tissue markers in endomyocardial biopsies have been identified that may be useful in assessing prognosis in heart failure patients. Such tissue markers include ubiquitin, Gremlin-1, cyclophilin A, and heterogeneous nuclear ribonucleoprotein C. In some cases, tissue markers have been found to be independent of and even superior to clinical indices and serum markers in predicting prognosis for heart failure patients. In some cases, these novel tissue markers appear to offer prognostic information even in the setting of an otherwise negative endomyocardial biopsy. Copyright © 2014 Elsevier Inc.

Full Text Available Heart failure (HF is a serious debilitating condition with poor survival rates and an increasing level of prevalence. Heart failure is associated with an increase in renal norepinephrine spillover, which is an independent predictor of mortality in HF patients. The excessive sympatho-excitation that is a hallmark of heart failure has long-term effects that contribute to disease progression. An increase in directly recorded renal sympathetic nerve activity has also been recorded in animal models of heart failure. This review will focus on the mechanisms controlling sympathetic nerve activity to the kidney during normal conditions and alterations in these mechanisms during heart failure. In particular the roles of afferent reflexes and central mechanisms will be discussed.

Anemia is a frequent comorbidity of heart failure and is associated with poor outcomes. Anemia in heart failure is considered to develop due to a complex interaction of iron deficiency, kidney disease, and cytokine production, although micronutrient insufficiency and blood loss may contribute. Currently, treatment of anemia of heart failure lacks clear targets and specific therapy is not defined. Intravenous iron use has been shown to benefit anemic as well as nonanemic patients with heart failure. Treatment with erythropoietin-stimulating agents has been considered alone or in combination with iron, but robust evidence to dictate clear guidelines is not currently available. Available and emerging new agents in the treatment of anemia of heart failure will need to be tested in randomized, controlled studies. PMID:23403618

To report an analysis of the concept of cardiotoxic heart failure in breast cancer survivors. Despite numerous studies describing cardiotoxic effects of breast cancer therapies, the literature lacks consistent terminology to describe cancer treatment-induced heart failure, defined by the authors as 'cardiotoxic heart failure'. Breast cancer survivors who develop heart failure may not fit existing conceptual models. A concept analysis of cardiotoxic heart failure in breast cancer survivors is needed to integrate previous research findings and establish the scientific foundation for future intervention research. Concept analysis. An integrative review (1999-2014) was conducted to examine aetiologies and risk factors for heart failure in female breast cancer survivors. Databases searched were CINAHL, Cochrane Library, EmBase, Medline and Scopus. Walker and Avant's method for concept analysis includes: select concept; determine purpose; identify uses; define attributes; identify model case; describe borderline, related and contrary cases; identify antecedents/consequences; define empirical referents. In the literature, substantial variation was noted in terminology for breast cancer treatment-induced cardiotoxicity. The authors define cardiotoxic heart failure in breast cancer survivors as chronic heart failure resulting from breast cancer treatment-induced cardiotoxicity among women without pre-existing heart failure diagnosis. No studies were found that described quality of life or tested interventions to preserve quality of life for this population. Prospective studies are needed to develop interventions for symptom management to improve quality of life in breast cancer survivors with heart failure. New conceptual paradigms may be needed to improve outcomes for this vulnerable population. © 2016 John Wiley & Sons Ltd.

Abstract In patients with left ventricular heart failure (HF), the development of pulmonary hypertension (PH) and right ventricular (RV) dysfunction are frequent and have important impact on disease progression, morbidity, and mortality, and therefore warrant clinical attention. Pulmonary hypertension related to left heart disease (LHD) by far represents the most common form of PH, accounting for 65–80% of cases. The proper distinction between pulmonary arterial hypertension and PH-LHD may be challenging, yet it has direct therapeutic consequences. Despite recent advances in the pathophysiological understanding and clinical assessment, and adjustments in the haemodynamic definitions and classification of PH-LHD, the haemodynamic interrelations in combined post- and pre-capillary PH are complex, definitions and prognostic significance of haemodynamic variables characterizing the degree of pre-capillary PH in LHD remain suboptimal, and there are currently no evidence-based recommendations for the management of PH-LHD. Here, we highlight the prevalence and significance of PH and RV dysfunction in patients with both HF with reduced ejection fraction (HFrEF) and HF with preserved ejection fraction (HFpEF), and provide insights into the complex pathophysiology of cardiopulmonary interaction in LHD, which may lead to the evolution from a ‘left ventricular phenotype’ to a ‘right ventricular phenotype’ across the natural history of HF. Furthermore, we propose to better define the individual phenotype of PH by integrating the clinical context, non-invasive assessment, and invasive haemodynamic variables in a structured diagnostic work-up. Finally, we challenge current definitions and diagnostic short falls, and discuss gaps in evidence, therapeutic options and the necessity for future developments in this context. PMID:26508169

We undertook a mixed-methods evaluation of a Web-based conferencing service (virtual consult) between general practitioners (GPs) and cardiologists in managing patients with heart failure in the community to determine its effect on use of specialist heart failure services and acceptability to GPs. All cases from June 2015 to October 2016 were recorded using a standardized recording template, which recorded patient demographics, medical history, medications, and outcome of the virtual consult for each case. Quantitative surveys and qualitative interviewing of 17 participating GPs were also undertaken. During this time, 142 cases were discussed-68 relating to a new diagnosis of heart failure, 53 relating to emerging deterioration in a known heart failure patient, and 21 relating to therapeutic issues. Only 17% required review in outpatient department following the virtual consultation. GPs reported increased confidence in heart failure management, a broadening of their knowledge base, and a perception of overall better patient outcomes. These data from an initial experience with Heart Failure Virtual Consultation present a very positive impact of this strategy on the provision of heart failure care in the community and acceptability to users. Further research on the implementation and expansion of this strategy is warranted. © 2017 The Authors.

Acute heart failure represents the first cause of hospitalization in elderly persons and is the main determinant of the huge healthcare expenditure related to heart failure. Despite therapeutic advances, the prognosis of acute heart failure is poor, with in-hospital mortality ranging from 4% to 7%, 60- to 90-day mortality ranging from 7% to 11%, and 60- to 90-day rehospitalization from 25% to 30%. Several factors including cardiovascular and noncardiovascular conditions as well as patient-related and iatrogenic factors may precipitate the rapid development or deterioration of signs and symptoms of heart failure, thus leading to an acute heart failure episode that usually requires patient hospitalization. The primary prevention of acute heart failure mainly concerns the prevention, early diagnosis, and treatment of cardiovascular risk factors and heart disease, including coronary artery disease, while the secondary prevention of a new episode of decompensation requires the optimization of heart failure therapy, patient education, and the development of an effective transition and follow-up plan.

Heart failure affects 1-2% of the UK population with prevalence rates predicted to rise over the next decade. Ineffective education for patients with heart failure can lead to a failure to adhere to guidance, reduced self-care and increased hospital readmissions. The National Institute for Health and Care Excellence (NICE) and the World Health Organization (WHO) have issued clear guidelines on patient-centred care in heart failure, particularly in relation to patients' cultural and linguistic needs. Patients with heart failure should have access to an interpreter or advocate if needed. Furthermore, heart failure educational materials should be tailored to suit the individual and be accessible to people who do not speak or read English. This article explores the practice recommendations for these patients with heart failure and provides an overview of current guidelines associated with optimal patient outcomes. It also includes practical advice on translation services, and information and educational materials available for patients with heart failure who do not speak English.

With the intention to summarize the currently available evidence on the pathophysiological relevance of inflammation in heart failure, this review addresses the question whether inflammation is a cause or consequence of heart failure, or both. This review discusses the diversity (sterile, para-inflammation, chronic inflammation) and sources of inflammation and gives an overview of how inflammation (local versus systemic) can trigger heart failure. On the other hand, the review is outlined how heart failure-associated wall stress and signals released by stressed, malfunctioning, or dead cells (DAMPs: e.g., mitochondrial DNA, ATP, S100A8, matricellular proteins) induce cardiac sterile inflammation and how heart failure provokes inflammation in various peripheral tissues in a direct (inflammatory) and indirect (hemodynamic) manner. The crosstalk between the heart and peripheral organs (bone marrow, spleen, gut, adipose tissue) is outlined and the importance of neurohormonal mechanisms including the renin angiotensin aldosteron system and the ß-adrenergic nervous system in inflammation and heart failure is discussed. Inflammation and heart failure are strongly interconnected and mutually reinforce each other. This indicates the difficulty to counteract inflammation and heart failure once this chronic vicious circle has started and points out the need to control the inflammatory process at an early stage avoiding chronic inflammation and heart failure. The diversity of inflammation further addresses the need for a tailored characterization of inflammation enabling differentiation of inflammation and subsequent target-specific strategies. It is expected that the characterization of the systemic and/or cardiac immune profile will be part of precision medicine in the future of cardiology.

The relevance of gene mutations leading to heart diseases and hence heart failure has become evident. The risk for and the course of heart failure depends on genomic variants and mutations underlying the so-called genetic predisposition. Genetic contribution to heart failure is highly heterogenous and complex. For any patient with a likely inherited heart failure syndrome, genetic counselling is recommended and important. In the last few years, novel sequencing technologies (named next-generation sequencing - NGS) have dramatically improved the availability of molecular testing, the efficiency of genetic analyses, and moreover reduced the cost for genetic testing. Due to this development, genetic testing has become increasingly accessible and NGS-based sequencing is now applied in clinical routine diagnostics. One of the most common reasons of heart failure are cardiomyopathies such as the dilated or the hypertrophic cardiomyopathy. Nearly 100 disease-associated genes have been identified for cardiomyopathies. The knowledge of a pathogenic mutation can be used for genetic counselling, risk and prognosis determination, therapy guidance and hence for a more effective treatment. Besides, family cascade screening for a known familial, pathogenic mutation can lead to an early diagnosis in affected individuals. At that timepoint, a preventative intervention could be used to avoid or delay disease onset or delay disease progression. Understanding the cellular basis of genetic heart failure syndromes in more detail may provide new insights into the molecular biology of physiological and impaired cardiac (cell) function. As our understanding of the molecular and genetic pathophysiology of heart failure will increase, this might help to identify novel therapeutic targets and may lead to the development of new and specific treatment options in patients with heart failure. © 2018 The Authors.

Full Text Available Heart failure (HF imposes significant economic and public health burdens upon modern society. It is known that disturbances in neurohormonal status play an important role in the pathogenesis of HF. Therapeutics that antagonize selected neurohormonal pathways, specifically the renin-angiotensin-aldosterone and sympathetic nervous systems, have significantly improved patient outcomes in HF. Nevertheless, mortality remains high with about 50% of HF patients dying within five years of diagnosis thus mandating ongoing efforts to improve HF management. The discovery of short noncoding microRNAs (miRNAs and our increasing understanding of their functions, has presented potential therapeutic applications in complex diseases, including HF. Results from several genome-wide miRNA studies have identified miRNAs differentially expressed in HF cohorts suggesting their possible involvement in the pathogenesis of HF and their potential as both biomarkers and as therapeutic targets. Unravelling the functional relevance of miRNAs within pathogenic pathways is a major challenge in cardiovascular research. In this article, we provide an overview of the role of miRNAs in the cardiovascular system. We highlight several HF-related miRNAs reported from selected cohorts and review their putative roles in neurohormonal signaling.

Hospitalization for acute heart failure (AHF) is one of the burdensome aspects of 21st century medicine, leading to significant debilitating symptoms, high morbidity and mortality and consuming significant portion of the health care budget. Management of AHF is thought-provoking given the heterogeneity of the patient population, absence of a universally accepted definition, incomplete understanding of the pathophysiology and the beneficial and adverse effects of currently used therapies and lack of robust evidence-based guidelines. The article will discuss the clinical approach to the patients admitted with AHF, reviewing types of intervention (both approved and investigational) and will delineate their role and timing in specific AHF presentations. One of the challenges of AHF management is to effectively treat the subsets of patients with slow improvement or those with refractory AHF or early recurrence (worsening HF) during their initial admission. Unfortunately, the majority of these patients are at increased risk for subsequent complications and adverse outcomes. Therefore, considerable efforts in AHF management should be directed towards this population. Regretfully, to date no specific targeted therapy was proven beneficial for these patients, being one of the leading reasons for the lack of improvement in AHF outcomes over the last 30 years.

Severe tricuspid regurgitation (TR) secondary to interference pacemaker (PM) cable is a rare cause of progressive right heart failure (HF), which can worsen patient outcomes. We present 3 clinical cases of right HF secondary to TR after PM implantation. In these patients the clinic is right HF, which can appear early, as in our second patient, or after years of implementation of the PM, as in the first and third patients. The diagnosis is confirmed by echocardiography, the most accurate 3D, followed by transesophageal. The 2D transthoracic can not detect it, because it has low sensitivity for TR associated with PM. Medical treatment is always the first choice, since any other procedure carries significant morbidity and mortality. Probably this is a condition that we will diagnose with increasing frequency, because there are more and more patients with devices and, at the same time, the diagnostic tools are improving.

The goal of this study was to determine nurses' knowledge of heart failure (HF) self-management education principles. The study was exploratory and descriptive and included a convenience sample. Research took place in a large midwestern health care system that included a university-based hospital, community hospitals, and home or palliative care. Subjects included 300 nurses who provide care to patients with HF. The outcome measures included overall and topic specific perceptions of basic information important to HF self-management. Topics included diet, fluids or weight, signs or symptoms of worsening condition, medications, and exercise. A 20-item, true or false written survey was administered between February 2000 and April 2000. Of the 300 nurses surveyed, 92% were registered nurses and 8% were licensed practical nurses; 38% worked in a large university-based hospital; 44% were employed at 5 community hospitals; and 18% worked in home or hospice-palliative care. Mean HF self-management knowledge score was 15.2 +/- 2.0. Registered nurses scored significantly higher than licensed practical nurses (15.3 vs 14.1; P =.004). Individual questions with overall scores 30% and time. Overall analysis of variance indicated differences by work experience. HF nurses (primary population) scored higher than critical-care, medical-surgical, or telemetry floor nurses (16.2 +/- 1.7; 15.1 +/- 1.8; and 14.7 +/- 2.0, respectively; P part of their daily job role.

Abstract Hypothyroidism is a risk factor of heart failure (HF) in the general population. However, the relationship between hypothyroidism and clinical outcomes in patients with established HF is still inconclusive. We conducted a systematic review and meta-analysis to clarify the association of hypothyroidism and all-cause mortality as well as cardiac death and/or hospitalization in patients with HF. We searched MEDLINE via PubMed, EMBASE, and Scopus databases for studies of hypothyroidism and clinical outcomes in patients with HF published up to the end of January 2015. Random-effects models were used to estimate summary relative risk (RR) statistics. We included 13 articles that reported RR estimates and 95% confidence intervals (95% CIs) for hypothyroidism with outcomes in patients with HF. For the association of hypothyroidism with all-cause mortality and with cardiac death and/or hospitalization, the pooled RR was 1.44 (95% CI: 1.29–1.61) and 1.37 (95% CI: 1.22–1.55), respectively. However, the association disappeared on adjustment for B-type natriuretic protein level (RR 1.17, 95% CI: 0.90–1.52) and in studies of patients with mean age hypothyroidism associated with increased all-cause mortality as well as cardiac death and/or hospitalization in patients with HF. Further diagnostic and therapeutic procedures for hypothyroidism may be needed for patients with HF. PMID:26222845

The incidence of heart failure (HF) and diabetes mellitus is rapidly increasing and is associated with poor prognosis. In spite of the advances in therapy, HF remains a major health problem with high morbidity and mortality. When HF and diabetes coexist, clinical outcomes are significantly worse. The relationship between these two conditions has been studied in various experimental models. However, the mechanisms for this interrelationship are complex, incompletely understood, and have become a matter of considerable clinical and research interest. There are only few animal models that manifest both HF and diabetes. However, the translation of results from these models to human disease is limited and new models are needed to expand our current understanding of this clinical interaction. In this review, we discuss mechanisms of insulin signaling and insulin resistance, the clinical association between insulin resistance and HF and its proposed pathophysiologic mechanisms. Finally, we discuss available animal models of insulin resistance and HF and propose requirements for future new models. PMID:23456447

Heart Failure continues to be a major public health problem associated with high mortality and morbidity. Heart Failure is the leading cause of hospitalization for persons older than 65 years, has a poor prognosis and is associated with poor quality of life. More than 5.3 million American adults are living with heart failure. Despite maximum medical therapy and frequent hospitalizations to stabilize their condition, one in five heart failure patients die within the first year of diagnosis. Several disease-management programs have been proposed and tested to improve the quality of heart failure care. Studies have shown that hospital admissions and emergency room visits decrease with increased nursing interventions in the home and community setting. An alternative strategy for promoting self-management of heart failure is the use of electronic home monitoring. The purpose of this study was to examine what effects heart failure has on patient's quality of life that had been monitoring on an electronic home monitor longer than 2 months. Twenty-one questionnaires were given to patients utilizing an electronic home monitor by their home health agency nurse. Eleven patients completed the questionnaire. The findings showed that there is some deterioration in quality of life with more association with the physical aspects of life than with the emotional aspects of life, which probably was due to the small sample size. There was no significant difference in readmission rates in patients utilizing an electronic home monitor. Further research is needed with a larger population of patients with chronic heart failure and other chronic diseases which may provide more data, and address issues such as patient compliance with self-care, impact of heart failure on patient's quality of life, functional capacity, and heart failure patient's utilization of the emergency rooms and hospital. Telemonitoring holds promise for improving the self-care abilities of persons with HF.

The sinus node inhibitor ivabradine was approved for patients with heart failure (HF) after the ivabradine and outcomes in chronic HF (SHIFT [Systolic Heart Failure Treatment With the IF Inhibitor Ivabradine Trial]) trial. Our objective was to characterize the proportion of patients with HF eligible for ivabradine and the representativeness of the SHIFT trial enrollees compared with those in the Swedish Heart Failure Registry. We examined 26 404 patients with clinical HF from the Swedish Heart Failure Registry and divided them into SHIFT type (left ventricular ejection fraction 50% of target dose. From those patients who had repeated visits within 6 months (n=5420) and 1 year (n=6840), respectively, 10.2% (n=555) and 10.6% (n=724) of SHIFT-type patients became ineligible, 77.3% (n=4188) and 77.3% (n=5287) remained ineligible, and 4.6% (n=252) and 4.9% (n=335) of non-SHIFT-type patients became eligible for initiation of ivabradine. From the Swedish Heart Failure Registry, 14.2% of patients with HF were eligible for ivabradine. These patients more commonly were not receiving target β-blocker dose. Over time, a minority of patients became ineligible and an even smaller minority became eligible. © 2017 American Heart Association, Inc.

Physicians working in Europe and the United States should suspect Chagas heart failure in every patient coming from Latin America with chronic heart failure. Diagnosis should be confirmed by positive serology. Right bundle branch block and left anterior fascicular block on 12-lead electrocardiogram, enlarged cardiac silhouette with no pulmonary congestion on chest X-ray and left ventricular apical aneurysm on echocardiography are the distinctive features of this condition. The clinical course is poorer than that of non-Chagas heart failure; however, medical treatment is similar. Implantable cardioverter-defibrillators are useful in the primary and secondary prevention of sudden cardiac death. Cardiac resynchronisation therapy can be given to patients on optimal medical therapy and with lengthened QRS complex. Heart transplantation is the treatment of choice for patients with end-stage Chagas heart failure.

The heart failure epidemic is driven mainly by population aging and the improving survival of patients with cardiovascular risk factors. Aging heart failure patients are affected by multiple concurrent comorbidities and geriatric syndromes, the most important of which are frailty and cognitive impairment. The purpose of this review is to provide clinicians with practical advice on how to individualize the care of older heart failure patients. Frailty and cognitive impairment are common in older heart failure patients. Frailty is increasingly recognized as a key risk factor for functional decline, health service utilization and mortality in aging heart failure patients. Similarly, cognitive impairment impairs patients' ability for self-care and leads to adverse outcomes. Simple and efficient instruments exist to screen for these conditions. Heart failure patients who are frail or cognitively impaired are best looked after in a disease management setting that is deployed in a more integrated healthcare system with access to specialized geriatric consultants. Optimal care planning requires knowledge of these conditions as well as patient and caregiver engagement. Frailty and cognitive impairment are central features of the heart failure syndrome in aging patients and should be routinely considered in assessment and care planning.

Chronic heart failure is a cardiovascular disorder with high prevalence and incidence worldwide. The course of heart failure is characterized by periods of stability and instability. Decompensation of heart failure is associated with frequent and prolonged hospitalizations and it worsens the prognosis for the disease and increases cardiovascular mortality among affected patients. It is therefore important to monitor these patients carefully to reveal changes in their condition. Remote monitoring has been designed to facilitate an early detection of adverse events and to minimize regular follow-up visits for heart failure patients. Several new devices have been developed and introduced to the daily practice of cardiology departments worldwide. Areas covered: Currently, special tools and techniques are available to perform remote monitoring. Concurrently there are a number of modern cardiac implantable electronic devices that incorporate a remote monitoring function. All the techniques that have a remote monitoring function are discussed in this paper in detail. All the major studies on this subject have been selected for review of the recent data on remote monitoring of HF patients and demonstrate the role of remote monitoring in the therapeutic decision making for heart failure patients. Expert commentary: Remote monitoring represents a novel intensified follow-up strategy of heart failure management. Overall, theoretically, remote monitoring may play a crucial role in the early detection of heart failure progression and may improve the outcome of patients.

Mammalian organs vary widely in regenerative capacity. Poorly regenerative organs, such as the heart are particularly vulnerable to organ failure. Once established, heart failure commonly results in mortality. The Hippo pathway, a kinase cascade that prevents adult cardiomyocyte proliferation and regeneration, is upregulated in human heart failure. Here we show that deletion of the Hippo pathway component Salvador (Salv) in mouse hearts with established ischaemic heart failure after myocardial infarction induces a reparative genetic program with increased scar border vascularity, reduced fibrosis, and recovery of pumping function compared with controls. Using translating ribosomal affinity purification, we isolate cardiomyocyte-specific translating messenger RNA. Hippo-deficient cardiomyocytes have increased expression of proliferative genes and stress response genes, such as the mitochondrial quality control gene, Park2. Genetic studies indicate that Park2 is essential for heart repair, suggesting a requirement for mitochondrial quality control in regenerating myocardium. Gene therapy with a virus encoding Salv short hairpin RNA improves heart function when delivered at the time of infarct or after ischaemic heart failure following myocardial infarction was established. Our findings indicate that the failing heart has a previously unrecognized reparative capacity involving more than cardiomyocyte renewal.

Hospitalization for heart failure amongst younger men has increased. The reason for this is unknown but it coincides with the obesity epidemic. The aim of this study was to evaluate the association between childhood BMI (Body Mass Index) and BMI change during puberty for risk of adult heart failure in men. Using the BMI Epidemiology Study (BEST), a population-based study in Gothenburg, Sweden, we collected information on childhood BMI at age 8 years and BMI change during puberty (BMI at age 20 - BMI at 8) for men born 1945-1961, followed until December 2013 (n = 37 670). BMI was collected from paediatric growth charts and mandatory military conscription tests. Information on heart failure was retrieved from high-quality national registers (342 first hospitalizations for heart failure). BMI change during puberty was independently of childhood BMI associated with risk of heart failure in a nonlinear J-shaped manner. Subjects in the upper quartile of BMI change during puberty (Q4) had more than twofold increased risk of heart failure compared with subjects in Q1 [HR (Hazard Ratio) = 2.29, 95% CI (Confidence Interval) 1.68-3.12]. Childhood BMI was not independently associated with risk of heart failure. Boys developing overweight during puberty (HR 3.14; 95% CI 2.25-4.38) but not boys with childhood overweight that normalized during puberty (HR 1.12, 95% CI 0.63-2.00) had increased risk of heart failure compared with boys without childhood or young adult overweight. BMI change during puberty is a novel risk factor for adult heart failure in men. © 2018 The Association for the Publication of the Journal of Internal Medicine.

Acute decompensated heart failure is a common emergency department presentation with significant associated morbidity and mortality. Heart failure accounts for more than 1 million hospitalizations annually, with a steadily increasing incidence as our population ages. This issue reviews recent literature regarding appropriate management of emergency department presentations of acute decompensated heart failure, with special attention to newer medication options. Emergency department management and appropriate interventions are discussed, along with critical decision-making points in resuscitation for both hypertensive and hypotensive patients. [Points & Pearls is a digest of Emergency Medicine Practice].

The aim of this project is to study heart failure in sheep that have gousiekte by using technetium 99m to determine the blood flow. Gousiekte is a congestive cardiomyopathy that occurs in ruminant animals. It is characterised by a latent period of 2-6 weeks followed by a sudden death. It appears that during gousiekte the stroke volume decreases with about 40% and the PFI increases with more than a 100%. The decrease in stroke volume is observed by means of an electromagnetic bloodflow meter. The greater change in PFI than stroke volume during gousiekte is a sign that there is congestive failure of the left ventricle. A decrease in ejection fraction has been observed by a loss of value lower than 30% after the final congestive phase has been reached. Normally 7,4 plus minus 0,3 contractions of a sheep's heart are needed to pump the blood from the right to left side of the heart. Complete congestive failure during gousiekte can decrease the effectiveness of the heart so that 50 contractions are needed, in other words a PFI value of 50. Two phases can be distinguished during the development of gousiekte namely a compensation phase and a decompensation phase. The PFI as criterion is used to establish the influence of certain drugs with an inotropic effect and to establish whether a gousiekte heart can protentiate after administration of the drugs. The findings are positive which shows than energy abnormalities are not primary causes of gousiekte. As a model for heart failure gousiekte can be compared with other well known models of heart failure such a volume overload, pressure overload and coronary ligatures in sheep. The by-product of this research is the development and possible application of the technetium isotope method to diagnose heart failure in sheep

In the United States alone, ∼14,000 children are hospitalised annually with acute heart failure. The science and art of caring for these patients continues to evolve. The International Pediatric Heart Failure Summit of Johns Hopkins All Children's Heart Institute was held on February 4 and 5, 2015. The 2015 International Pediatric Heart Failure Summit of Johns Hopkins All Children's Heart Institute was funded through the Andrews/Daicoff Cardiovascular Program Endowment, a philanthropic collaboration between All Children's Hospital and the Morsani College of Medicine at the University of South Florida (USF). Sponsored by All Children's Hospital Andrews/Daicoff Cardiovascular Program, the International Pediatric Heart Failure Summit assembled leaders in clinical and scientific disciplines related to paediatric heart failure and created a multi-disciplinary "think-tank". The purpose of this manuscript is to summarise the lessons from the 2015 International Pediatric Heart Failure Summit of Johns Hopkins All Children's Heart Institute, to describe the "state of the art" of the treatment of paediatric cardiac failure, and to discuss future directions for research in the domain of paediatric cardiac failure.

Leukocyte concentration in blood is a classical marker of systemic inflammation. Whether high leukocyte counts are associated with incidence of heart failure (HF) is unknown. This population-based study explored whether the leukocyte concentrations were associated with incidence of hospitalizations due to HF. Leukocyte counts were measured in 16 940 men from the general population (mean age 44 years) without history of myocardial infarction or stroke. Incidence of hospitalizations due to HF (primary diagnosis) was monitored over 23 years of follow-up, in relation to quartiles of leukocytes. Subjects with myocardial infarction during follow-up were censored in the main analysis. During the follow-up, 436 men were hospitalized due to HF. Incidence of HF hospitalizations was increased in men with high leukocyte counts. After adjustments for confounding factors, the adjusted hazards ratio (HR, 95% CI) for HF hospitalization was 1.00 (reference), 1.26 (0.93 to 1.7), 1.24 (0.91 to 1.7), and 1.73 (1.3 to 2.3), respectively, for men with leukocytes in the 1st, 2nd, 3rd, and 4th (highest) quartiles (trend, Pleukocyte counts in middle-aged men were associated with increased long-term incidence of HF hospitalizations.

Chronic heart failure (CHF) is a serious, common condition associated with frequent hospitalisation. Several different disease management interventions (clinical service organisation interventions) for patients with CHF have been proposed. To update the previously published review which assessed the effectiveness of disease management interventions for patients with CHF. A number of databases were searched for the updated review: CENTRAL, (the Cochrane Central Register of Controlled Trials) and DARE, on The Cochrane Library, ( Issue 1 2009); MEDLINE (1950-January 2009); EMBASE (1980-January 2009); CINAHL (1982-January 2009); AMED (1985-January 2009). For the original review (but not the update) we had also searched: Science Citation Index Expanded (1981-2001); SIGLE (1980-2003); National Research Register (2003) and NHS Economic Evaluations Database (2001). We also searched reference lists of included studies for both the original and updated reviews. Randomised controlled trials (RCTs) with at least six months follow up, comparing disease management interventions specifically directed at patients with CHF to usual care. At least two reviewers independently extracted data and assessed study quality. Study authors were contacted for further information where necessary. Data were analysed and presented as odds ratios (OR) with 95% confidence intervals (CI). Twenty five trials (5,942 people) were included. Interventions were classified by: (1) case management interventions (intense monitoring of patients following discharge often involving telephone follow up and home visits); (2) clinic interventions (follow up in a CHF clinic) and (3) multidisciplinary interventions (holistic approach bridging the gap between hospital admission and discharge home delivered by a team). The components, intensity and duration of the interventions varied, as did the 'usual care' comparator provided in different trials.Case management interventions were associated with reduction in all

This study sought to determine the use of intravenous fluids in the early care of patients with acute decompensated heart failure (HF) who are treated with loop diuretics. Intravenous fluids are routinely provided to many hospitalized patients. We conducted a retrospective cohort study of patients admitted with HF to 346 hospitals from 2009 to 2010. We assessed the use of intravenous fluids during the first 2 days of hospitalization. We determined the frequency of adverse in-hospital outcomes. We assessed variation in the use of intravenous fluids across hospitals and patient groups. Among 131,430 hospitalizations for HF, 13,806 (11%) were in patients treated with intravenous fluids during the first 2 days. The median volume of administered fluid was 1,000 ml (interquartile range: 1,000 to 2,000 ml), and the most commonly used fluids were normal saline (80%) and half-normal saline (12%). Demographic characteristics and comorbidities were similar in hospitalizations in which patients did and did not receive fluids. Patients who were treated with intravenous fluids had higher rates of subsequent critical care admission (5.7% vs. 3.8%; p fluid treatment varied widely across hospitals (range: 0% to 71%; median: 12.5%). Many patients who are hospitalized with HF and receive diuretics also receive intravenous fluids during their early inpatient care, and the proportion varies among hospitals. Such practice is associated with worse outcomes and warrants further investigation. Copyright © 2015 American College of Cardiology Foundation. Published by Elsevier Inc. All rights reserved.

Full Text Available Background: Intracellular signaling pathways involved in skeletal myosin heavy chain (MyHC isoform alterations during heart failure (HF are not completely understood. We tested the hypothesis that diaphragm expression of mitogen-activated protein kinases (MAPK and myogenic regulatory factors is changed in rats with myocardial infarction (MI induced HF. Methods: Six months after MI rats were subjected to transthoracic echocardiography. After euthanasia, infarcted rats were subdivided in MI/HF- group (with no HF evidence; n=10, and MI/HF+ (with right ventricular hypertrophy and lung congestion; n=10. Sham-operated rats were used as controls (n=10. MyHC isoforms were analyzed by electrophoresis. Statistical analysis: ANOVA and Pearson correlation. Results: MI/HF- had left cardiac chambers dilation with systolic and diastolic left ventricular dysfunction. Cardiac injury was more intense in MI/HF+ than MI/HF-. MyHC I isoform percentage was higher in MI/HF+ than MI/HF-, and IIb isoform lower in MI/HF+ than Sham. Left atrial diameter-to-body weight ratio positively correlated with MyHC I (p=0.005 and negatively correlated with MyHC IIb (p=0.02. TNF-a serum concentration positively correlated with MyHC I isoform. Total and phosphorylated ERK was lower in MI/HF- and MI/HF+ than Sham. Phosphorylated JNK was lower in MI/HF- than Sham. JNK and p38 did not differ between groups. Expression of NF-κB and the myogenic regulatory factors MyoD, myogenin, and MRF4 was similar between groups. Conclusion: Diaphragm MyHC fast-to-slow shift is related to cardiac dysfunction severity and TNF-a serum levels in infarcted rats. Reduced ERK expression seems to participate in MyHC isoform changes. Myogenic regulatory factors and NF-κB do not modulate diaphragm MyHC distribution during chronic HF.

Inflammation has been implicated in the pathogenesis of heart failure (HF). In addition to their direct involvement as mediators in the pathogenesis of HF, inflammatory cytokines and related mediators could also be suitable markers for risk stratification and prognostication in HF patients. Many reports have suggested that inflammatory cytokines may predict adverse outcome in these patients. However, most studies have been limited in sample size and lacking full adjustment with the most recent and strongest biochemical predictor such as NT-proBNP and high sensitivity troponins. Furthermore, a number of pre-analytical and analytical aspects of cytokine measurements may limit their use as biomarkers. This review focuses on technical, informative and practical considerations concerning the clinical use of inflammatory cytokines as prognostic biomarkers in HF. We focus on the predictive value of tumor necrosis factor (TNF) α, the TNF family receptors sTNFR1 and osteoprotegerin, interleukin (IL)-6 and its receptor gp130, the chemokines MCP-1, IL-8, CXCL16 and CCL21 and the pentraxin PTX-3 in larger prospective fully adjusted studies. No single inflammatory cytokine provides sufficient discrimination to justify the transition to everyday clinical use as a prognosticator in HF. However, while subjecting potential new HF markers to rigorous comparisons with "gold-standard" markers, such as NT-proBNP, using receiver operating characteristics (ROCs) and HF risk models, makes sense from a clinical standpoint, it may pose a threat to a broadening of mechanistic insight if the new markers are dismissed solely on account of lower statistical power.

The Dietary Approaches to Stop Hypertension (DASH) diet effectively reduces blood pressure. In observational studies, the association between diets consistent with DASH and risk of coronary heart disease and stroke has been examined with varying results. We hypothesized that diets consistent with the DASH diet would be associated with a lower incidence of heart failure (HF). We conducted a prospective observational study in 36 019 participants in the Swedish Mammography Cohort who were aged 48 to 83 years and without baseline HF, diabetes mellitus, or myocardial infarction. Diet was measured using food-frequency questionnaires. We created a score to assess consistency with the DASH diet by ranking the intake of DASH diet components and 3 additional scores based on food and nutrient guidelines. Cox proportional hazards models were used to calculate rate ratios of HF-associated hospitalization or death, determined using the Swedish inpatient and cause-of-death registers between January 1, 1998, and December 31, 2004. During 7 years, 443 women developed HF. Women in the top quartile of the DASH diet score based on ranking DASH diet components had a 37% lower rate of HF after adjustment for age, physical activity, energy intake, education status, family history of myocardial infarction, cigarette smoking, postmenopausal hormone use, living alone, hypertension, high cholesterol concentration, body mass index (calculated as weight in kilograms divided by height in meters squared), and incident myocardial infarction. Rate ratios (95% confidence intervals) across quartiles were 1 [Reference], 0.85 (0.66-1.11), 0.69 (0.54-0.88), and 0.63 (0.48-0.81); P(trend) diets consistent with the DASH diet are associated with lower rates of HF.

We present the case of a newborn admitted to the intensive care unit with a heart failure of difficult medical management. A large ductus arteriosus was found. It was surgically corrected, but the heart failure persisted and did not improve with medical treatment. Incidentally, a big Galen's vein aneurysm was found. Galen's vein aneurysm is a rare congenital pathology, originated by a fusion defect of the internal cerebral veins. Due to its low resistance, it produces a picture of high-output heart failure. Large defects may contain 50% to 60% of cardiac output. An aneurysm may be suspected in each newborn or infant with clinical picture of heart failure and right cardiac chamber dilation without any evidence of structural cardiac anomaly

Heart failure and chronic kidney disease have increasing incidence and prevalence owing in part to the aging population and increasing rates of hypertension, diabetes, and other cardiovascular and kidney disease risk factors. The presence of one condition also has a strong influence on the other, leading to greater risks for hospitalization, morbidity, and death, as well as very high health care costs. Despite the frequent coexistence of heart failure and chronic kidney disease, many of the pivotal randomized trials that guide the management of heart failure have excluded patients with more advanced stages of chronic kidney disease. In this Core Curriculum article, management of a challenging, yet not unusual, case of heart failure with reduced ejection fraction in a patient with stage 4 chronic kidney disease provides an opportunity to review the relevant literature and highlight gaps in our knowledge.

Cardiac pacemakers, implantable cardioverter defibrillators (ICD) and systems for cardiac resynchronization therapy (CRT) represent an important component of heart failure therapy. Pacemakers only play a role in bradycardia-associated heart failure and require optimal programming to prevent ventricular desynchronization. Primary prophylactic ICD implantation is indicated in patients with a left ventricular ejection fraction of ≤ 35 %, clinical stages NYHA II-III and a life expectancy > 1 year. The CRT is indicated in patients with a left bundle branch block but only in individual cases for other QRS morphologies of heart failure should always include remote monitoring to detect events early and to implement treatment accordingly. New developments include quadripolar left ventricular leads and pacing from multiple sites simultaneously thus enabling better resynchronization. Stimulation for modulation of cardiac contractility and the autonomous nervous system are currently being clinically tested. The optimal utilization of device therapy improves the course of heart failure and prevents cardiac decompensation and fatalities.

Heart failure (HF) is a major cause of mortality and morbidity, representing a leading cause of death and hospitalization among U.S. Medicare beneficiaries. Advances in science have generated effective interventions to reduce adverse outcomes in HF, particularly in patients with reduced left ventricular ejection fraction. Unfortunately, effective therapies for heart failure are often not utilized in an effective, safe, timely, equitable, patient-centered, and efficient manner. Further, the risk of adverse outcomes for HF remains high. The last decades have witnessed the growth of efforts to measure and improve the care and outcomes of patients with HF. This paper will review the evolution of quality measurement for HF, including a brief history of quality measurement in medicine; the measures that have been employed to characterize quality in heart failure; how the measures are obtained; how measures are employed; and present and future challenges surrounding quality measurement in heart failure. © 2012 New York Academy of Sciences.

Availability of cardiac medications in hospice for acute symptom management of heart failure is unknown. This study explored hospice approaches to cardiac medications for patients with heart failure. Descriptive study using a quantitative survey of 46 US hospice agencies and clinician interviews. Of 31 hospices that provided standard home medication kits for acute symptom management, only 1 provided medication with cardiac indications (oral furosemide). Only 22% of the hospice agencies had a specific cardiac medication kit. Just over half (57%) of the agencies could provide intravenous inotropic therapy, often in multiple hospice settings. Clinicians described an individualized approach to cardiac medications for patients with heart failure. This study highlights opportunities for practice guidelines that inform medical therapy for hospice patients with heart failure. © The Author(s) 2015.
Hyogo Prefectural Amagasaki General Medical Center has formed a heart failure team. Here, I report on the role of the pharmacist in this heart failure team at this hospital. Patient education is one of the roles of the pharmacist. It is the pharmacist's responsibility to improve medication adherence among patients. For this purpose, the pharmacist uses a brochure created by the heart failure team. The brochure outlines drug information in an easy-to-understand manner. The roles of a pharmacist were addressed in a lecture presented to the heart failure team. These lectures helped improve the pharmaceutical knowledge of the team, allowing the team to prescribe medicines more safely and appropriately. Maintaining co-operation between hospital and community pharmacies is another important role of a hospital pharmacist. This allows patients to be properly educated by pharmacists even after discharge from the hospital.

The causes of heart failure are diverse. Inherited causes represent an important clinical entity and can be divided into 2 major categories: familial and metabolic cardiomyopathies. The distinct features that might be present in early disease states can become broadly overlapping with other diseases, such as in the case of inherited cardiomyopathies (ie, familial hypertrophic cardiomyopathy or mitochondrial diseases). In this review article, we focus on genetic issues related to advanced heart failure. Because of the emerging importance of this topic and its breadth, we sought to focus our discussion on the known genetic forms of heart failure syndromes, genetic testing, and newer data on pharmacogenetics and therapeutics in the treatment of heart failure, to primarily encourage clinicians to place a priority on the diagnosis and treatment of these potentially treatable conditions.

Previous systematic reviews and meta-analyses consistently show the positive effect of exercise-based rehabilitation for heart failure (HF) on exercise capacity; however, the direction and magnitude of effects on health-related quality of life, mortality and hospital admissions in HF remain less certain. This is an update of a Cochrane systematic review previously published in 2010. To determine the effectiveness of exercise-based rehabilitation on the mortality, hospitalisation admissions, morbidity and health-related quality of life for people with HF. Review inclusion criteria were extended to consider not only HF due to reduced ejection fraction (HFREF or 'systolic HF') but also HF due to preserved ejection fraction (HFPEF or 'diastolic HF'). We updated searches from the previous Cochrane review. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (Issue1, 2013) from January 2008 to January 2013. We also searched MEDLINE (Ovid), EMBASE (Ovid), CINAHL (EBSCO) and PsycINFO (Ovid) (January 2008 to January 2013). We handsearched Web of Science, bibliographies of systematic reviews and trial registers (Controlled-trials.com and Clinicaltrials.gov). Randomised controlled trials of exercise-based interventions with six months' follow-up or longer compared with a no exercise control that could include usual medical care. The study population comprised adults over 18 years and were broadened to include individuals with HFPEF in addition to HFREF. Two review authors independently screened all identified references and rejected those that were clearly ineligible. We obtained full-text papers of potentially relevant trials. One review author independently extracted data from the included trials and assessed their risk of bias; a second review author checked data. We included 33 trials with 4740 people with HF predominantly with HFREF and New York Heart Association classes II and III. This latest update identified a further 14 trials. The overall risk

Hospitalized patients with heart failure who are malnourished present a worse prognosis than those with an adequate nutritional status. We undertook this study to assess whether a nutritional intervention in malnourished hospitalized patients with heart failure benefits morbidity and mortality. A multicenter, randomized, controlled clinical trial was conducted. A total of 120 malnourished hospitalized patients due to acute heart failure were randomised to conventional heart failure treatment or conventional heart failure treatment combined with an individualized nutritional intervention. The primary endpoint of this study was a composite of all-cause death or readmission for worsening of HF, with a maximum follow-up of 12 months. Analysis was by intention to treat. Recruitment was stopped early according to the study protocol after completing the follow-up of the first 120 patients enrolled (59 in the intervention group and 61 in the control group). Both groups were homogeneous in baseline characteristics. At 12 months, the primary outcome occurred in 27.1% of patients in the intervention group and in 60.7% of patients in the control group (hazard ratio 0.45; 95% confidence interval [CI], 0.19-0.62, p = 0.0004). In total, 20.3% of patients died in the intervention group and 47.5% in the control group (hazard ratio 0.37, 95% CI, 0.19-0.72, p = 0.003). Readmission due to heart failure was also lower in the intervention group (10.2 vs. 36.1%, p = 0.001). Nutritional intervention in malnourished hospitalized patients with heart failure reduces the risk of death from any cause and the risk of readmission for worsening of heart failure (ClinicalTrial.govNCT01472237).

Full Text Available Objectives: Anemia is prevalent in heart failures and is an independent risk factor for adverse clinical outcomes in patients with CHF. The aim of the present study was to determine the prevalence of anemia in elderly with systolic heart failure hospitalized in Alborz Hospital of Karaj in 2009. Methods & Materials: This is a descriptive retrospective study that reviewed 154 medical records of elderly with systolic heart failure during 2002-2008. Demographic, laboratory, and echocardiography data were reviewed from medical records. Anemia was defined as a hemoglobin level below 12 g/dL in women and below 13 g/dL in men in this study. Data were analysed by descriptive statistics such as frequency distribution, mean, standard deviation and independent group test and Pearson correlation coefficient. Results: The findings indicated that prevalence of anemia in elderly with systolic heart failure was (42.9%. There was significant difference between mean level of hemoglobin in heart failure with chronic obstructive pulmonary disease (P=0.000. level of hemoglobin significant associated with age (P=0.014 and left ventricular ejection fraction (0.022. Conclusion: This study indicated that anemia is frequent among elderly with systolic heart failure and anemia may be associated with age, LVEF and COPD. More research into the mechanisms of anemia in CHF is needed.

Progressions in acute cardiac care have improved survival after acute myocardial infarction, but in contraposition with this, there has been an increase in mortality because of heart failure. For this reason congestive heart failure is an increasingly widespread, costly and deadly disease, frequently named as epidemic of the XXI century. Despite advancement in modern treatment, mortality rate in heart failure patients remains high. In these patients more importance was attributed in the management of the left ventricle dysfunction. In fact, the heart failure patients have still a poor prognosis due to the ineluctable progression of contractile dysfunction and ventricular remodeling. The classical management of left ventricle dysfunction includes the pharmacological treatment with beta-blockers, ACE-inhibitors and aldosterone antagonists, and various surgical or electrophysiological interventions. Emerging evidence suggests that myocardium dysfunction is also due to substrate metabolism alterations. In particular, there is evidence that, in the failing heart, shifting metabolism away from a preference for fatty acids towards more carbohydrate oxidation could recover contractile function. Trimetazidine has been shown to improve symptoms and ventricular function and to have a beneficial effect on the inflammatory profile and endothelial function in these patients. Recently, it has been suggested that trimetazidine could also reduce ventricular remodeling, slowing down the progression of pump failure, and improve prognosis. These results suggest that trimetazidine is a useful adjunct to our current armamentarium for the treatment of heart failure patients.

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

Poor sleep quality is common and is associated with poor quality of life and health status in patients with heart failure. However, few investigators have focused on the impact of impaired sleep quality on survival in heart failure. To examine whether self-reported sleep quality is associated with prognosis in patients with heart failure. The study sample consisted of 204 patients with heart failure. Sleep quality was measured with the Pittsburgh Sleep Quality Index. Poor sleepers were defined as patients with scores greater than 5 on the index. Patients were followed up for a median of 364 days to determine cardiac events (a composite of cardiac death, hospitalizations, or emergency department visits for cardiac reasons). Multivariable Cox proportional hazard regression was used to examine whether poor sleepers were at a higher risk than good sleepers for shorter cardiac event-free survival after covariates were adjusted for. Of 204 patients, 129 (63%) reported poor sleep quality. Poor sleepers were 2.5 times more likely to have a shorter cardiac event-free survival (95% CI, 1.164-5.556) than were good sleepers after covariates were controlled for. Impaired sleep quality was prevalent in patients with heart failure and was associated with poor cardiac event-free survival. Clinicians should assess and manage sleep quality in patients with heart failure to improve outcomes. ©2016 American Association of Critical-Care Nurses.

We recently identified a set of plasma microRNAs (miRNAs) that are downregulated in patients with heart failure in comparison with control subjects. To better understand their meaning and function, we sought to validate these circulating miRNAs in 3 different well-established rat and mouse heart failure models, and correlated the miRNAs to parameters of cardiac function. The previously identified let-7i-5p, miR-16-5p, miR-18a-5p, miR-26b-5p, miR-27a-3p, miR-30e-5p, miR-199a-3p, miR-223-3p, miR-423-3p, miR-423-5p and miR-652-3p were measured by means of quantitative real time polymerase chain reaction (qRT-PCR) in plasma samples of 8 homozygous TGR(mREN2)27 (Ren2) transgenic rats and 8 (control) Sprague-Dawley rats, 6 mice with angiotensin II-induced heart failure (AngII) and 6 control mice, and 8 mice with ischemic heart failure and 6 controls. Circulating miRNA levels were compared between the heart failure animals and healthy controls. Ren2 rats, AngII mice and mice with ischemic heart failure showed clear signs of heart failure, exemplified by increased left ventricular and lung weights, elevated end-diastolic left ventricular pressures, increased expression of cardiac stress markers and reduced left ventricular ejection fraction. All miRNAs were detectable in plasma from rats and mice. No significant differences were observed between the circulating miRNAs in heart failure animals when compared to the healthy controls (all P>0.05) and no robust associations with cardiac function could be found. The previous observation that miRNAs circulate in lower levels in human patients with heart failure could not be validated in well-established rat and mouse heart failure models. These results question the translation of data on human circulating miRNA levels to experimental models, and vice versa the validity of experimental miRNA data for human heart failure.
Full Text Available Heart failure potentially developing in most of heart diseases is a progressive process associated with high morbidity and mortality. Almost 3/4 of patients die within five years after first hospitalization because of heart failure. The main treatment for patients with terminal heart failure is heart transplantation. Left ventricular assist device is a main alternative to heart transplantation. We present case of long-term mechanical support applied in patients with heart failure class IV NYHA, refractory to medical therapy. Long-term implantation of mechanical heart support system may serve as an effective bridge to heart transplantation in patients with advanced congestive heart failure.
Full Text Available Background. Aim was to elucidate the role of toll-like receptor 9 (TLR9 in cardiac inflammation and septic heart failure in a murine model of polymicrobial sepsis. Methods. Sepsis was induced via colon ascendens stent peritonitis (CASP in C57BL/6 wild-type (WT and TLR9-deficient (TLR9-D mice. Bacterial load in the peritoneal cavity and cardiac expression of inflammatory mediators were determined at 6, 12, 18, 24, and 36 h. Eighteen hours after CASP cardiac function was monitored in vivo. Sarcomere length of isolated cardiomyocytes was measured at 0.5 to 10 Hz after incubation with heat-inactivated bacteria. Results. CASP led to continuous release of bacteria into the peritoneal cavity, an increase of cytokines, and differential regulation of receptors of innate immunity in the heart. Eighteen hours after CASP WT mice developed septic heart failure characterised by reduction of end-systolic pressure, stroke volume, cardiac output, and parameters of contractility. This coincided with reduced cardiomyocyte sarcomere shortening. TLR9 deficiency resulted in significant reduction of cardiac inflammation and a sustained heart function. This was consistent with reduced mortality in TLR9-D compared to WT mice. Conclusions. In polymicrobial sepsis TLR9 signalling is pivotal to cardiac inflammation and septic heart failure.

Full Text Available The commonest cause of chronic heat failure in China is ischemic heart disease, followed by hypertension and valvular heart disease. Echocardiography is essential in establishing a diagnosis as well as helping to identify a cause and to monitor progress. Management includes nonpharmacological as well as pharmacological treatment, and self-care with careful monitoring of salt and fluid intake as well as regular weight measurement. Care planning and team-based care are essential in managing patients with chronic heart failure, who often have concurrent multimorbidity and are receiving polypharmacy.

Despite current treatments, morbidity and mortality of patients with heart failure remain high. The late diagnosis of heart failure, the insufficient heart failure treatment (i.e. not using the appropriate drugs, prescribing lower doses of drugs than recommended, etc.), and a poor coordination between different health care levels, may explain, at least in part, these figures. The Management of Heart Failure in Cardiology and Primary Care (MICCAP) program has been developed with the aim of optimising the integrated management of patients with heart failure between Primary Care and Cardiology, through the improvement of coordination between both health care levels. This includes continuous medical education to reinforce the diagnostic and therapeutic skills of general practitioners in the field of heart failure. The rationale and objectives of the MICCAP program are summarised in this article. Copyright © 2018 Sociedad Española de Médicos de Atención Primaria (SEMERGEN). Publicado por Elsevier España, S.L.U.

Skilled nursing facilities (SNFs) have emerged as an integral component of care for older adults with heart failure (HF). Despite their prominent role, poor clinical outcomes for the medically complex patients with HF managed in SNFs are common. Barriers to providing quality care include poor transitional care during hospital-to-SNF and SNF-to-community discharges, lack of HF training among SNF staff, and a lack of a standardized care process among SNF facilities. Although no evidence-based practice standards have been established, various measures and tools designed to improve HF management in SNFs are being investigated. In this review, we discuss the challenges of HF care in SNFs as well as potential targets and recommendations that can help improve care with respect to transitions, HF management within SNFs, and modifiable factors within facilities. Policy considerations that might help catalyze improvements in SNF-based HF management are also discussed. Copyright Â© 2016 Elsevier Inc. All rights reserved.

AIMS: Heart failure with preserved (HFpEF) and mid-range ejection fraction (HFmrEF) are becoming the most prevalent forms of heart failure. Patients with HFpEF/HFmrEF in atrial fibrillation (AF) have poorer survival and quality of life, but the mechanism underpinning this is unknown. We sought...... left ventricular ejection fraction. At rest, AF patients had significantly increased pulmonary capillary wedge pressure, lower cardiac index and reduced left ventricular stroke work index, despite similar resting heart rate. Under resting conditions, calculated oxygen consumption and systemic...... arteriovenous oxygen gradient were not different between the two groups. During supine cycling at similar levels of workload, AF patients exhibited a reduced capacity to increase their oxygen consumption and this was accompanied by a persistently impaired cardiac index and left ventricular stroke work index...
Conclusions: 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.
Activation of the neuro-hormonal system is a pathophysiological consequence of heart failure. Neuro-hormonal activation promotes metabolic changes, such as insulin resistance, and determines an increased use of non-carbohydrate substrates for energy production. Fasting blood ketone bodies as well as fat oxidation are increased in patients with heart failure, yielding a state of metabolic inefficiency. The net result is additional depletion of myocardial adenosine triphosphate, phosphocreatine and creatine kinase levels with further decreased efficiency of mechanical work. In this context, manipulation of cardiac energy metabolism by modification of substrate use by the failing heart has produced positive clinical results. The results of current research support the concept that shifting the energy substrate preference away from fatty acid metabolism and towards glucose metabolism could be an effective adjunctive treatment in patients with heart failure. The additional use of drugs able to partially inhibit fatty acids oxidation in patients with heart failure may therefore yield a significant protective effect for clinical symptoms and cardiac function improvement, and simultaneously ameliorate left ventricular remodelling. Certainly, to clarify the exact therapeutic role of metabolic therapy in heart failure, a large multicentre, randomised controlled trial should be performed. PMID:28785448

To review the updated research progress about the application of echocardiography in resynchronization treatment of chronic heart failure patients. The data used in this review were from PubMed, published in English and using the key terms "heart failure", "echocardiography" and "cardiac resynchronization therapy". Relevant articles were reviewed and selected to address the stated purpose. Increasing numbers of studies have suggested the importance of echocardiography in resynchronization treatment of chronic heart failure patients. Echocardiography can evaluate atrioventricular, inter- and intra-ventricular mechanical dyssynchrony before cardiac resynchronization therapy (CRT), as a guidance to assess the optimal left ventricular (LV) pacing location, optimize the atrioventricular and interventricular delays and predict response to CRT. Echocardiography is both non invasive and easily repeatable, and plays a crucial role in appraisal of heart synchronism, instruction of actuator placement, optimization of the device procedure, and prediction of the response to CRT.

The aim of this study was to psychometrically evaluate the Heart Failure Screening Tool (Heart-FaST) via: (1) examination of internal construct validity; (2) testing of scale function in accordance with design; and (3) recommendation for change/s, if items are not well adjusted, to improve psychometric credential. Self-care is vital to the management of heart failure. The Heart-FaST may provide a prospective assessment of risk, regarding the likelihood that patients with heart failure will engage in self-care. Psychometric validation of the Heart-FaST using Rasch analysis. The Heart-FaST was administered to 135 patients (median age = 68, IQR = 59-78 years; 105 males) enrolled in a multidisciplinary heart failure management program. The Heart-FaST is a nurse-administered tool for screening patients with HF at risk of poor self-care. A Rasch analysis of responses was conducted which tested data against Rasch model expectations, including whether items serve as unbiased, non-redundant indicators of risk and measure a single construct and that rating scales operate as intended. The results showed that data met Rasch model expectations after rescoring or deleting items due to poor discrimination, disordered thresholds, differential item functioning, or response dependence. There was no evidence of multidimensionality which supports the use of total scores from Heart-FaST as indicators of risk. Aggregate scores from this modified screening tool rank heart failure patients according to their "risk of poor self-care" demonstrating that the Heart-FaST items constitute a meaningful scale to identify heart failure patients at risk of poor engagement in heart failure self-care. © 2018 John Wiley & Sons Ltd.

Hyperthyroidism is a common side effect encountered in patients prescribed long-term amiodarone therapy for cardiac arrhythmias. We previously studied 354 patients prescribed amiodarone in whom the occurrence of hyperthyroidism was associated with major adverse cardiovascular events including heart failure, myocardial infarction, ventricular arrhythmias, stroke and even death . We now present a case of amiodarone-induced hyperthyroidism complicated by isolated right heart failure and pulmonary hypertension that resolved with treatment of hyperthyroidism. Detailed quantitative echocardiography enables improved understanding of the haemodynamic mechanisms underlying the condition.

Full Text Available Summary of the Consensus Statement: This statement has been prepared keeping Indian heart failure patients in mind. Optimal management of CHF improves quality of life, reduces hospitalization rates and prolongs survival for people with this condition. Echocardiography is the single most useful test in the evaluation of heart failure, and is necessary to confirm the diagnosis. Plasma B-natriuretic peptide (BNP measurements may be useful in excluding CHF but not mandatory in India. Educate people with CHF about lifestyle changes (e.g., increase physical activity levels, reduce salt intake and manage weight. Educate people with CHF about CHF symptoms and how to manage fluid load. Avoid prescribing drugs that exacerbate CHF. Prescribe angiotensin-converting enzyme inhibitors (ACEI at effective doses for people with all grades of systolic heart failure, and titrate to the highest recommended dose tolerated. Angiotensin II receptor antagonists (ARA may be used as alternatives in people who cannot tolerate ACEIs. Mineralocorticoid receptor antagonists (MRAs should also be used. For people with stabilised systolic heart failure, prescribe beta-blockers that have been shown to improve outcome in heart failure (e.g., bisoprolol, carvedilol, extended release metoprolol or nebivolol. Titrate to the highest recommended dose tolerated. Prescribe diuretics, digoxin and nitrates for people already using ACEIs and beta-blockers to manage symptoms as indicated. For people who have systolic heart failure (New York Heart Association (NYHA Class II-IV despite appropriate doses of ACEIs and diuretics, consider prescribing spironolactone. Eplerenone can be considered in certain setting especially post myocardial infarction though it is more expensive. Consider direct sinus node inhibition with ivabradine for people with CHF who have impaired systolic function, have had a recent heart failure hospitalisation and are in sinus rhythm with a heart rate >70 bpm despite

Matrix metalloproteinase (MMP) is up-regulated during heart failure (HF) and influences ventricular remodeling. We hypothesized that disparity between MMP-9 and tissue inhibitors of MMP-1 (TIMP-1) results in clinical manifestations and is related to prognostic risk in patients with chronic HF. Plasma levels of MMP-9, TIMP-1, and brain natriuretic peptide (BNP) were measured in 173 patients with chronic HF. Combined endpoints of worsening HF events were assessed during follow-up (median 109 months). MMP-9 and TIMP-1 levels and the MMP-9/TIMP-1 ratio increased with increasing severity of the New York Heart Association class (P for trend = 0.003, 0.011, and 0.005, respectively). Patients with HF events (n = 35) had significantly higher MMP-9 than those without HF events (P = 0.004). Kaplan-Meier analysis demonstrated a higher probability of HF events with high MMP-9 values (>23.2 ng/mL; P = 0.005). A multivariate Cox proportional hazard model showed that high MMP-9 values were an independent predictor of HF events (hazard ratio, 3.73; 95% confidence interval (CI), 1.03-13.46; P = 0.043). In patients with lower BNP levels (≤210 pg/mL), the adjusted hazard ratio for HF events was 3.63 (95% CI, 1.20-11.02; P = 0.023) among patients with high MMP-9 values compared with patients with low BNP and low MMP-9 values. MMP-9 and TIMP-1 levels correlate with the severity of chronic HF. MMP-9 is a strong predictor of HF events, suggesting that a disparity between MMP-9 and TIMP-1 levels and increased MMP-9 levels may help predict HF events. © 2017 The Authors.

Systematic reviews examining associations of depressive disorder with coronary heart disease and stroke produce mixed results. Failure to consider reverse causation and dose-response patterns may have caused inconsistencies in evidence. This prospective cohort study on depressive disorder, coronary heart disease, and stroke analysed reverse causation and dose-response effects using four 5-year and three 10-year observation cycles (total follow up 24 years) based on multiple repeat measures of exposure. Participants in the Whitehall II study (n = 10,036, 31,395 person-observations, age at start 44.4 years) provided up to six repeat measures of depressive symptoms via the 30-item General Health Questionnaire (GHQ-30) and one measure via Center for Epidemiologic Studies Depression Scale (CES-D). The cohort was followed up for major coronary events (coronary death/nonfatal myocardial infarction) and stroke (stroke death/morbidity) through the national mortality register Hospital Episode Statistics, ECG-screening, medical records, and self-report questionnaires. GHQ-30 caseness predicted stroke over 0-5 years (age-, sex- and ethnicity-adjusted HR 1.60, 95% CI 1.1-2.3) but not over 5-10 years (HR 0.94, 95% CI 0.6-1.4). Using the last 5-year observation cycle, cumulative GHQ-30 caseness was associated with incident coronary heart disease in a dose-response manner (1-2 times a case: HR 1.12, 95% CI 0.7-1.7; 3-4 times: HR 2.06, 95% CI 1.2-3.7), and CES-D caseness predicted coronary heart disease (HR 1.81, 95% CI 1.1-3.1). There was evidence of a dose-response effect of depressive symptoms on risk of coronary heart disease. In contrast, prospective associations of depressive symptoms with stroke appeared to arise wholly or partly through reverse causation.
Full Text Available Sunit-Preet Chaudhry,1 Garrick C Stewart2 1Division of Cardiology, St Vincent Indianapolis, Indianapolis, IN, 2Division of Cardiovascular Medicine, Center for Advanced Heart Disease, Brigham and Women’s Hospital, Boston, MA, USA Abstract: Heart failure is a complex clinical syndrome resulting from impairment of ventricular filling or ejection of blood associated with symptoms of dyspnea, fatigue, as well as peripheral and/or pulmonary edema. This syndrome is progressive and characterized by worsening quality of life despite escalating levels of care, affecting 5.7 million Americans with an annual cost of over $30 billion US dollars. Treatment for this syndrome has evolved over three distinct eras: the nonpharmacological era, the pharmacological era, and the device era, with the focus shifting from symptomatic relief to decreasing morbidity and mortality. Over the past 10 years, the field has undergone a renaissance, with the development of new pharmacologic, hemodynamic monitoring, and device therapies proven to improve outcomes in patients with heart failure. This article will review several recent innovations in the management of patients with heart failure. Keywords: heart failure, heart-assist devices, disease management

The purpose of this article was to review the clinical management of patients with heart failure with preserved ejection fraction (HFPEF). For this critical review, electronic databases (MEDLINE, EMBASE, PubMed) were searched for relevant basic research studies and randomized clinical trials recently published or presented at major meetings. Details of in-progress or planned studies were obtained from the ClinicalTrials.gov website. The range of publication dates was the year 2000 to 2015. Search terms included HFPEF, heart failure with preserved ejection fraction, HFPSF, heart failure with preserved systolic function, diastolic heart failure, diastolic dysfunction, HFNEF, heart failure with normal ejection fraction, treatment, management, therapy. Patients with HFPEF account for up to half of all patients with a clinical diagnosis of HF. Key contributing factors include hypertension, obesity, and atrial fibrillation, and other chronic diseases, including diabetes, chronic obstructive pulmonary disease, and anemia, frequently coexist. To date, large-scale clinical trials, particularly those focused on antagonism of the renin-angiotensin-aldosterone system, have provided limited evidence of clinical benefit. The aggressive management of contributing factors, including hypertension, atrial fibrillation, and myocardial ischemia, is key in the management of HFPEF. New insights into the mechanisms and thus the identification of potential therapeutic strategies are urgently required. Copyright © 2015 Elsevier HS Journals, Inc. All rights reserved.

The ubiquity of the Internet is changing the way people obtain their health information. Although there is an abundance of heart failure information online, the quality and health literacy demand of these information are still unknown. The purpose of this study is to evaluate the quality and health literacy demand (readability, understandability, and actionability) of the heart failure information found online. Google, Yahoo, Bing, Ask.com, and DuckDuckGo were searched for relevant heart failure Web sites. Two independent raters then assessed the quality and health literacy demand of the included Web sites. The quality of the heart failure information was assessed using the DISCERN instrument. Readability was assessed using 7 established readability tests. Finally, understandability and actionability were assessed using the Patient Education Materials Assessment Tool for Print Materials. A total of 46 Web sites were included in this analysis. The overall mean quality rating was 46.0 ± 8.9 and the mean readability score was 12.6 grade reading level. The overall mean understandability score was 56.3% ± 16.2%. Finally, the overall mean actionability score was 34.7% ± 28.7%. The heart failure information found online was of fair quality but required a relatively high health literacy level. Web content authors need to consider not just the quality but also the health literacy demand of the information found in their Web sites. This is especially important considering that low health literacy is likely prevalent among the usual audience.

While exercise-based cardiac rehabilitation has a beneficial effect on heart failure hospitalization and mortality, it is limited by the presence of chronotropic incompetence (CI) in some patients. This study explored the feasibility of using wearable devices to assess impaired chronotropic response in heart failure patients. Forty patients with heart failure (left ventricular ejection fraction, LVEF: 44.6 ± 5.8; age: 54.4 ± 11.7) received ECG Holter and accelerometer to monitor heart rate (HR) and physical activities during symptom-limited treadmill exercise testing, 6-min hall walk (6MHW), and 24-h daily living. CI was defined as maximal HR during peak exercise testing failing to reach 70% of age-predicted maximal HR (APMHR, 220 - age). The correlation between HR and physical activities in Holter-accelerometer recording was analyzed. Of 40 enrolled patients, 26 were able to perform treadmill exercise testing. Based on exercise test reports, 13 (50%) of 26 patients did not achieve at least 70% of APMHR (CI patients). CI patients achieved a lower % APMHR (62.0 ± 6.3%) than non-CI patients who achieved 72.0 ± 1.2% of APMHR (P failure patients who took treadmill exercise testing. The wearable Holter-accelerometer recording could help to identify impaired chronotropic response to physical activities in heart failure patients. ClinicalTrials.gov ID NCT02358603 .

Full Text Available Angie Veverka, Jennifer L SalinasWingate University School of Pharmacy, Wingate, NC, USAAbstract: Nebivolol is a highly selective beta1-adrenergic blocker that also enhances nitric oxide bioavailability via the L-arginine-nitric oxide pathway, leading to vasodilation and decreased peripheral vascular resistance. It is marketed in Europe for the treatment of hypertension and heart failure and is currently being reviewed for use in the US by the Food and Drug Administration. Nebivolol appears to be well tolerated with an adverse event profile that is at least similar, if not better, than that of other beta-adrenergic blockers. Studies suggest that long-term therapy with nebivolol improves left ventricular function, exercise capacity, and clinical endpoints of death and cardiovascular hospital admissions in patients with stable heart failure. To date, it is one of the only beta-adrenergic blockers that have been exclusively studied in elderly patients. Additionally, the unique mechanism of action of nebivolol makes it a promising agent for treatment of chronic heart failure in high-risk patient populations, such as African Americans. This article will review the pharmacologic and pharmacokinetic properties of nebivolol as well as clinical studies assessing its efficacy for the treatment of heart failure.Keywords: nebivolol, beta-adrenergic blockers, heart failure
Full Text Available Iron deficiency and anemia affect approximately half of the chronic heart failure patients and they are associated with increased hospitalization rate, lower functional capacity, lower quality of life, and higher mortality. The exact mechanism of iron deficiency in heart failure patients is still not fully understood. Current guidelines recommend ferritin as the most accurate serum biomarker for the diagnosis of iron deficiency. The use of erythropoiesis-stimulating agents is no longer recommended because of the lack of improvement on mortality or hospital readmission rate, and it was associated with a higher rate of thromboembolic events. Intravenous iron replacement therapy is safe and generally well tolerated, with fewer side effects compared to oral administration. Large randomized studies with ferric carboxymaltose demonstrated its effectiveness and superiority to oral administration, and it was associated with a decreased rate of hospitalization rate and worsening heart failure, and improvement of functional capacity and quality of life. Intravenous iron supplementation for chronic heart failure is strongly recommended by European guidelines. Further studies are needed for a better knowledge of this complex pathology and determination of the long-term safety and effectiveness of iron administration in chronic heart failure patients. .
Atrial fibrillation in heart failure often occur together. The relationship between atrial fibrillation and heart failure has remained a subject of research. The main manifestation of the violation of hydrodynamics in heart failure is the increased end-diastolic pressure, which is transmitted through the intercommunicated system (left ventricle-left atrium-pulmonary veins-alveolar capillaries) causing increased pulmonary wedge pressure with the danger for pulmonary edema. End-diastolic pressure is the sum of left ventricle diastolic pressure and left atrial systolic pressure. Stopping the mechanical systole of the left atrium can reduce the pressure in the system in heart failure. Atrial fibrillation stops the mechanical systole of the left atrium and decreases the intercommunicating pressure and pulmonary wedge pressure. It is possible that atrial fibrillation is a mechanism for protection from increasing end-diastolic pressure and pulmonary wedge pressure, and prevents the danger of pulmonary edema. This hypothesis may explain the relationship between heart failure and atrial fibrillation and their frequent association. Copyright © 2014 Elsevier Ltd. All rights reserved.

Heart failure is now the third leading cause of cardiovascular death in developed countries and is also an important cause of morbidity and hospitalization that now represents the main cause of admissions among the elderly. In this study we present heart failure mortality trends in Spain developing over the last 20 years. Data on deaths due to heart failure were obtained from files supplied by the Spanish National Institute for Statistics. We present age-adjusted specific mortality rates over time analyzed by sex and geographic area. Poisson regression models were used to estimate trends. Heart failure is responsible for 4 to 8% of all-cause mortality in men and women, and for 12 to 20% of cardiovascular mortality overall, the the highest rates seen among the elderly and in Andalusia. The lowest rates are found in the Basque Country and some provinces of Castilla-Leon. Rates have tended to decrease over the last 20 years, but the rate of decrease has been slower in women, such that their mortality began to exceeded that of men from 1990 onwards. Mortality among the elderly has not changed significantly but the total number of deaths and morbidity are both increasing. Because the Spanish population is aging, we can foresee that chronic heart failure will require greater attention in the future.

A total of 44 elders with heart failure and 40 non-heart failure elders completed several questionnaires including: The Daily Spiritual Experiences Scale (DSES, Spirituality Index of Well-Being (SIWB, Center for Epidemiologic Studies Depression Scale (CES-D, and SF-12™ Health Survey. There were significant differences in the groups on gender and ethnicity; thus these variables were controlled in the analyses related to the dependent variables. After controlling for gender and ethnicity, there were significant differences in the physical component of quality of life and spiritual well-being. The heart failure patients had significantly lower physical quality of life but more spiritual well-being than the non-heart failure patients. There were no significant differences in daily spiritual experiences, mental component of quality of life, and depressive symptoms between the two groups.Keywords: spiritual experience, spiritual well-being, heart failure, depressive symptoms, quality of life, elders

The most common use of inotropes is among hospitalized patients with acute decompensated heart failure, with reduced left ventricular ejection fraction and with signs of end-organ dysfunction in the setting of a low cardiac output. Inotropes can be used in patients with severe systolic heart failure awaiting heart transplant to maintain hemodynamic stability or as a bridge to decision. In cases where patients are unable to be weaned off inotropes, these agents can be used until a definite or escalated supportive therapy is planned, which can include coronary revascularization or mechanical circulatory support (intra-aortic balloon pump, extracorporeal membrane oxygenation, impella, left ventricular assist device, etc.). Use of inotropic drugs is associated with risks and adverse events. This review will discuss the use of the inotropes digoxin, dopamine, dobutamine, norepinephrine, milrinone, levosimendan, and omecamtiv mecarbil. Long-term inotropic therapy should be offered in selected patients. A detailed conversation with the patient and family shall be held, including a discussion on the risks and benefits of use of inotropes. Chronic heart failure patients awaiting heart transplants are candidates for intravenous inotropic support until the donor heart becomes available. This helps to maintain hemodynamic stability and keep the fluid status and pulmonary pressures optimized prior to the surgery. On the other hand, in patients with severe heart failure who are not candidates for advanced heart failure therapies, such as transplant and mechanical circulatory support, inotropic agents can be used for palliative therapy. Inotropes can help reduce frequency of hospitalizations and improve symptoms in these patients.

To better understand the mechanisms contributing to improved exercise capacity with cardiac resynchronization therapy (CRT), we studied the effects of 6 mo of CRT on pulmonary O(2) uptake (Vo(2)) kinetics, exercise left ventricular (LV) function, and peak Vo(2) in 12 subjects (age: 56 ± 15 yr, peak Vo(2): 12.9 ± 3.2 ml·kg(-1)·min(-1), ejection fraction: 18 ± 3%) with heart failure. We hypothesized that CRT would speed Vo(2) kinetics due to an increase in stroke volume secondary to a reduction in LV end-systolic volume (ESV) and that the increase in peak Vo(2) would be related to an increase in cardiac output reserve. We found that Vo(2) kinetics were faster during the transition to moderate-intensity exercise after CRT (pre-CRT: 69 ± 21 s vs. post-CRT: 54 ± 17 s, P 0.05). CRT improved heart rate, measured as a lower resting and steady-state exercise heart rate and as faster heart rate kinetics after CRT (pre-CRT: 89 ± 12 s vs. post-CRT: 69 ± 21 s, P cardiac output reserve increased significantly post-CRT and was 22% higher at peak exercise post-CRT (both P cardiac output was due to both a significant increase in peak and reserve stroke volume and to a nonsignificant increase in heart rate reserve. Similar patterns in LV volumes as moderate-intensity exercise were observed at peak exercise. Cardiac output reserve was related to peak Vo(2) (r = 0.48, P chronic CRT-mediated cardiac factors that contribute, in part, to the speeding in Vo(2) kinetics and increase in peak Vo(2) in clinically stable heart failure patients.

We investigated cardio-respiratory coupling in patients with heart failure by quantification of bidirectional interactions between cardiac (RR intervals) and respiratory signals with complementary measures of time series analysis. Heart failure patients were divided into three groups of twenty, age and gender matched, subjects: with sinus rhythm (HF-Sin), with sinus rhythm and ventricular extrasystoles (HF-VES), and with permanent atrial fibrillation (HF-AF). We included patients with indication for implantation of implantable cardioverter defibrillator or cardiac resynchronization therapy device. ECG and respiratory signals were simultaneously acquired during 20 min in supine position at spontaneous breathing frequency in 20 healthy control subjects and in patients before device implantation. We used coherence, Granger causality and cross-sample entropy analysis as complementary measures of bidirectional interactions between RR intervals and respiratory rhythm. In heart failure patients with arrhythmias (HF-VES and HF-AF) there is no coherence between signals ( p failure groups causality between signals is diminished, but with significantly stronger causality of RR signal in respiratory signal in HF-VES. Cross-sample entropy analysis revealed the strongest synchrony between respiratory and RR signal in HF-VES group. Beside respiratory sinus arrhythmia there is another type of cardio-respiratory interaction based on the synchrony between cardiac and respiratory rhythm. Both of them are altered in heart failure patients. Respiratory sinus arrhythmia is reduced in HF-Sin patients and vanished in heart failure patients with arrhythmias. Contrary, in HF-Sin and HF-VES groups, synchrony increased, probably as consequence of some dominant neural compensatory mechanisms. The coupling of cardiac and respiratory rhythm in heart failure patients varies depending on the presence of atrial/ventricular arrhythmias and it could be revealed by complementary methods of time series

To evaluate the use of health care resources and their cost according to the effects of kidney failure in heart failure patients during 2-year follow-up in a population setting. Observational retrospective study based on a review of medical records. The study included patients ≥ 45 years treated for heart failure from 2008 to 2010. The patients were divided into 2 groups according to the presence/absence of KF. Main outcome variables were comorbidity, clinical status (functional class, etiology), metabolic syndrome, costs, and new cases of cardiovascular events and kidney failure. The cost model included direct and indirect health care costs. Statistical analysis included multiple regression models. The study recruited 1600 patients (prevalence, 4.0%; mean age 72.4 years; women, 59.7%). Of these patients, 70.1% had hypertension, 47.1% had dyslipidemia, and 36.2% had diabetes mellitus. We analyzed 433 patients (27.1%) with kidney failure and 1167 (72.9%) without kidney failure. Patients with kidney failure were associated with functional class III-IV (54.1% vs 40.8%) and metabolic syndrome (65.3% vs 51.9%, P<.01). The average unit cost was €10,711.40. The corrected cost in the presence of kidney failure was €14,868.20 vs €9,364.50 (P=.001). During follow-up, 11.7% patients developed ischemic heart disease, 18.8% developed kidney failure, and 36.1% developed heart failure exacerbation. Comorbidity associated with heart failure is high. The presence of kidney failure increases the use of health resources and leads to higher costs within the National Health System. Copyright © 2014 Sociedad Española de Cardiología.

The effect of enalapril on cerebral blood flow (CBF) was studied in 11 patients with chronic heart failure (NYHA II or III, dilated cardiomyopathy in 6 and old myocardial infarction in 5). CBF was evaluated by analyzing the Patlak-Plot curve obtained from radionuclide angiography with technetium-99m hexamethylpropylene amine oxime (99mTC-HM-PAO). Cardiac index (CI) and stroke volume (SV) were simultaneously measured by impedance cardiography. These measurements were performed before and at four weeks after daily administration of 5 mg enalapril. The stroke volume, cardiac index, and heart rate were not significantly changed after four weeks of enalapril administration. However, CBF was increased by 6.5% from 36.72 +/- 4.66 to 39.13 +/- 5.65 mL/100g/min (P < 0.05). These results suggest that enalapril increased cerebral blood flow, which was not related to increased cardiac output in congestive heart failure. Patlak-Plot analysis of radionuclide angiography using 99mTC-HM-PAO may be available for quantitative assessment of brain perfusion.

Autonomic nervous system dysfunction is common after acute stroke and is associated with elevated risk of cardiac arrhythmia and mortality. Heart rate variability and baroreceptor sensitivity have been investigated as parameters of autonomic nervous system dysfunction for the prediction of stroke outcome. We performed a systematic literature review on heart rate variability and baroreceptor sensitivity as parameters for autonomic nervous function in acute stroke. Twenty-two studies were included. Associations between heart rate variability or baroreceptor sensitivity and stroke severity, early and late complications, dependency and mortality were reported. However, interpretability of most studies and extrapolation to general stroke population are limited due to many confounding factors such as varying methodology, small sample sizes, survival selection, and exclusion of patients with frequently occurring comorbidities in stroke. Key issues, such as the effect of thrombolytic therapy on autonomic function, autonomic nervous system dysfunction in the hyperacute phase of stroke, and correlation with the risk of recurrent stroke have not been investigated. Also, nonlinear techniques have remained largely unexplored in this domain, in spite of their advantage to provide more solid evaluation in the occurrence of arrhythmia. Cardiac autonomic dysfunction, represented by reduced heart rate variability or impaired baroreceptor sensitivity, is associated with stroke severity, early and late complications, dependency, and mortality. Large-scale prospective studies applying internationally accepted standards of measures for analysis of heart rate variability and baroreceptor sensitivity are needed in patients with acute stroke. © 2015 World Stroke Organization.

Elevated heart rate could negatively influence cardiovascular risk in the general population. It can induce and promote the atherosclerotic process by means of several mechanisms involving endothelial shear stress and biochemical activities. Furthermore, elevated heart rate can directly increase heart ischemic conditions because of its skill in unbalancing demand/supply of oxygen and decreasing the diastolic period. Thus, many pharmacological treatments have been proposed in order to reduce heart rate and ameliorate the cardiovascular risk profile of individuals, especially those suffering from coronary artery diseases (CAD) and chronic heart failure (CHF). Ivabradine is the first pure heart rate reductive drug approved and currently used in humans, created in order to selectively reduce sinus node function and to overcome the many side effects of similar pharmacological tools (ie, β-blockers or calcium channel antagonists). The aim of our review is to evaluate the role and the safety of this molecule on CAD and CHF therapeutic strategies. PMID:24940047

Previous data are controversial about the association of renal artery stenosis (RAS) with clinical outcome in patients with heart failure. Definition of RAS in previous studies might not be appropriate. By definition of RAS with renal duplex sonography, we investigated the association of RAS with clinical outcome in patients with heart failure. In this retrospective study, we identified 164 patients with heart failure (New York Heart Association classification ≥II; left ventricular ejection fraction renal duplex sonography during hospital stay. RAS was defined as renal-aortic ratio ≥3.5 or a peak systolic velocity ≥200 cm/s (or both), or occlusion of the renal artery. Categorical data of patients were compared using the Chi-square test or Fisher's exact test. Cox proportional hazards regression modeling technique was used to investigate the prognostic significance of possible predictors. Finally, 143 patients were enrolled. Median follow-up time was 32 months (1-53 months). Twenty-two patients were diagnosed as RAS by renal duplex sonography, including 13 unilateral RAS (3 left RAS, 10 right RAS) and 9 bilateral RAS. There were more all-cause mortality and cardiovascular death in patients with RAS than patients without RAS. By multivariate analysis, RAS was a significant predictor for all-cause death and cardiovascular death (hazard ratio [HR] = 4.155, 95% confidence interval [CI]: 1.546-11.164, P = 0.005; and HR = 3.483, 95% CI: 1.200-10.104, P = 0.022, respectively). As for composite endpoint events, including death, nonfatal myocardial infarction, ischemic stroke or intracranial hemorrhage, rehospitalization for cardiac failure, and renal replacement therapy, only angiotensin-converting enzyme inhibitor or angiotensin-receptor blocker was significant predictor. RAS was not a significant predictor for composite endpoint events. Our data suggested that RAS is associated with a poorer clinical outcome in patients with heart failure.

Neonates are at risk of developing hypernatremic dehydration and its associated complications, such as stroke, dural sinus thrombosis and renal vein thrombosis. Pulmonary hypertension has not been described as a complication of hypernatremia. We report a case of a seven-day-old neonate with severe hypernatremic dehydration who went on to develop pulmonary hypertension and right heart failure needing extracorporeal membrane oxygenation (ECMO). Normal or high anion gap metabolic acidosis commonly accompanies hypernatremic dehydration. The presence of acidosis and/or hypoxia can delay the normal drop in pulmonary vascular resistance (PVR) after birth, causing pulmonary hypertension and right ventricular failure. A high index of suspicion is paramount to diagnose pulmonary hypertension and aggressive correction of the acidosis and hypoxia is needed. In the presence of severe right ventricular failure, ECMO can be used as a bridge to recovery while underlying metabolic derangements are being corrected.

The use of telemonitoring and telemedicine is a relatively new but quickly developing area in medicine. As new digital tools and applications are being created and used to manage medical conditions such as heart failure, many implications require close consideration and further study, including the effectiveness and safety of these telemonitoring tools in diagnosing, treating and managing heart failure compared to traditional face-to-face doctor–patient interaction. When compared to multidisciplinary intervention programs which are frequently hindered by economic, geographic and bureaucratic barriers, non-invasive remote monitoring could be a solution to support and promote the care of patients over time. Therefore it is crucial to identify the most relevant biological parameters to monitor, which heart failure sub-populations may gain real benefits from telehealth interventions and in which specific healthcare subsets these interventions should be implemented in order to maximise value.

The aim of this review is to present an up-to-date overview of the application of machine learning methods in heart failure including diagnosis, classification, readmissions and medication adherence. Recent studies have shown that the application of machine learning techniques may have the potential to improve heart failure outcomes and management, including cost savings by improving existing diagnostic and treatment support systems. Recently developed deep learning methods are expected to yield even better performance than traditional machine learning techniques in performing complex tasks by learning the intricate patterns hidden in big medical data. The review summarizes the recent developments in the application of machine and deep learning methods in heart failure management.

Since natriuretic peptides were successfully integrated into the clinical practice of heart failure (HF), the possibility of using new biomarkers to advance the management of affected patients has been explored. While a huge number of candidate HF biomarkers have been described recently, very few have made the difficult translation from initial promise to clinical application. These markers mirror the complex pathophysiology of heart failure at various levels: cell loss (troponin), fibrosis (ST2 and galectin-3), infection (procalcitonin), and renal disease (several renal markers). In this review, we examine the best emerging candidates for clinical assessment and management of patients with HF. © 2015 The Authors.

Full Text Available Objectives: To adapt the Self-Care of Heart Failure Index V6.2 to Portuguese and analyze self-care capability in maintenance, management and self-confidence in patients with heart failure attending nursing care services at two Portuguese hospitals. Method: Exploratory study, sample of 110 patients who attended the nursing care service for patients with heart failure at two Portuguese hospitals, carried out over a six-month period. Descriptive statistics and psychometric tests were used. Results: Internal consistency similar to the original scale. The patients consisted mostly of older adults with low self-care literacy, low values associated with physical activity and salt control in meals taken outside the home, and inadequate control of signs and symptoms. Conclusion: Patients present difficulties in maintenance and management of the disease, and are self-confident regarding it. This instrument enables individualized assessment leading to decision-making and adjusted action.

Heart failure affects millions of Americans and new diagnosis rates are expected to almost triple over the next 30 years as our population ages. Affective disorders including clinical depression and anxiety are common in patients with congestive heart failure. Furthermore, the presence of these disorders significantly impacts quality of life, medical outcomes, and healthcare service utilization. In recent years, the literature has attempted to describe potential pathophysiologic mechanisms relating affective disorders and psychosocial stress to heart failure. Several potential mechanisms have been proposed including autonomic nervous system dysfunction, inflammation, cardiac arrhythmias, and altered platelet function. These mechanisms are reviewed in this article. Additional novel mechanisms such as mental stress-induced myocardial ischemia are also discussed.

Sleep disorders represent a significant comorbidity in the heart failure population, and there is mounting evidence that treatment of sleep disorders such as obstructive sleep apnea can significantly improve cardiac function. However, the link between these two disorders is still not entirely clear. Recently, a novel neurohormonal pathway has been elucidated involving signaling molecules now collectively known as the orexins, which have been implicated in regulating autonomic function during sleep/wake cycles. Further evidence has mounted that orexin signaling is deeply perturbed in the setting of sleep disorders, and furthermore that abnormal orexin signaling may be implicated in the pathology of heart failure. The orexin signaling pathway represents an enticing novel target for both the treatment of sleep disorders as well as heart failure, and may represent one facet of the "missing link" between these two prevalent and often comorbid diseases.

BACKGROUND: Among patients with chronic heart failure, angiotensin-converting-enzyme (ACE) inhibitors reduce mortality and hospitalization, but the role of a renin inhibitor in such patients is unknown. We compared the ACE inhibitor enalapril with the renin inhibitor aliskiren (to test superiority...... or at least noninferiority) and with the combination of the two treatments (to test superiority) in patients with heart failure and a reduced ejection fraction. METHODS: After a single-blind run-in period, we assigned patients, in a double-blind fashion, to one of three groups: 2336 patients were assigned...... to receive enalapril at a dose of 5 or 10 mg twice daily, 2340 to receive aliskiren at a dose of 300 mg once daily, and 2340 to receive both treatments (combination therapy). The primary composite outcome was death from cardiovascular causes or hospitalization for heart failure. RESULTS: After a median...

BACKGROUND: The prevalence of depression is 4- to 5-fold higher in heart failure patients than in the general population. We examined the influence of depression on all-cause mortality in patients with heart failure. METHODS AND RESULTS: Using Danish medical registries, this nationwide population......-based cohort study included all patients with a first-time hospitalization for heart failure (1995-2014). All-cause mortality risks and 19-year mortality rate ratios were estimated based on Cox regression analysis, adjusting for age, sex, time period, comorbidity, and socioeconomic status. The analysis...... included 9636 patients with and 194 887 patients without a diagnosis of depression. Compared with patients without a history of depression, those with depression had higher 1-year (36% versus 33%) and 5-year (68% versus 63%) mortality risks. Overall, the adjusted mortality rate ratio was 1.03 (95% CI 1...
Full Text Available Cerebral arteriovenous fistula (AVF is a vascular malformation that is rare in the pediatric population. Older children with cerebral AVF tend to present with neurologic problems related to intracranial venous hypertension or intracranial hemorrhage. Cardiac and pulmonary complications following acute neurologic injury such as subarachnoid hemorrhage are common in adults, but are rarely reported in children. However, complications have been reported in cases of enterovirus 71 rhombencephalitis in infants and children and can cause high morbidity and mortality. Here, we report a 14-year-old boy who presented with cardiac failure associated with pulmonary edema following cerebral hemorrhagic stroke due to AVF. After aggressive investigation and management, we intervened before significant hypoxia and hypotension developed, potentially reducing the risk of long-term adverse neurologic consequences in this patient.

To evaluate the role of an open access heart failure service based at a teaching hospital for the diagnosis and treatment optimisation of patients with heart failure in the community and to identify measures that may further enhance the effectiveness of such a service. 963 patients with suspected heart failure seen over an eight year period referred by their general practitioners to the cardiology department at a district general hospital. Presence or absence of left ventricular systolic dysfunction (LVSD) (left ventricular ejection fraction 60 years of age (33.5% v 20.8%, p 0.5 on chest radiograph (44.3% v 17.8%, p < 0.001, RR 2.5) were found to be good predictors of LVSD. A normal ECG (negative predictive value 80.5%) and a cardiothoracic ratio of < 0.5 (negative predictive value 82.2%) can be used as baseline measures to identify patients with lower risk of developing LVSD (combined negative predictive value 87.9%). An open access heart failure clinic is effective for the diagnosis and management of chronic heart failure in community based patients. The presence of risk factors and simple baseline tests can be used to identify patients with LVSD in the community. The introduction of a protocol based on these findings into a referral system can improve the efficiency and cost effectiveness of such a service.

The aim of this study was to identify patients at-risk, enhancing self-care management of HF patients at home and reduce the disease exacerbations and readmissions. In this research according to standard heart failure guidelines and Semi-structured interviews with 10 heart failure Specialists, a draft heart failure rule set for alerts and patient instructions was developed. Eventually, the clinical champion of the project vetted the rule set. Also we designed a transactional system to enhance monitoring and follow up of CHF patients. With this system, CHF patients are required to measure their physiological measurements (vital signs and body weight) every day and to submit their symptoms using the app. additionally, based on their data, they will receive customized notifications and motivation messages to classify risk of disease exacerbation. The architecture of system comprised of six major components: 1) a patient data collection suite including a mobile app and website; 2) Data Receiver; 3) Database; 4) a Specialists expert Panel; 5) Rule engine classifier; 6) Notifier engine. This system has implemented in Iran for the first time and we are currently in the testing phase with 10 patients to evaluate the technical performance of our system. The developed expert system generates alerts and instructions based on the patient's data and the notify engine notifies responsible nurses and physicians and sometimes patients. Detailed analysis of those results will be reported in a future report. This study is based on the design of a telemonitoring system for heart failure self-care that intents to overcome the gap that occurs when patients discharge from the hospital and tries to accurate requirement of readmission. A rule set for classifying and resulting automated alerts and patient instructions for heart failure telemonitoring was developed. It also facilitates daily communication among patients and heart failure clinicians so any deterioration in health could be

Implanted devices in heart failure patients improve survival, but requires correct prescription, programming, and monitoring. Requirements change since heart failure is a dynamic condition. Repeated episodes of acute decompensation increase mortality. Events involve several processes converging to manifest with fluid congestion. Implantable devices identify changes such as those in rhythm, device function or hemodynamics. Incorporation of remote monitoring technology (TRUST Trial), enables tracking of these parameters and prompt notification of deviations, even if the patient remains asymptomatic. This may facilitate management of large patient volumes and enable pre-emptive treatment to improve outcomes in these high-risk patients.

Acute heart failure constitutes a heterogeneous clinical syndrome, whose pathophysiology is complex and not completely understood. Given the diversity of clinical presentations, several different pathophysiological mechanisms along with factors triggering circulatory decompensation are involved. This article discusses the available evidence on the pathophysiological phenomena attributed or/and associated with episodes of acute heart failure and describes different clinical profiles, which, from a clinical perspective, constitute a key element for therapeutic decision-making.

Mechanical circulatory support has emerged as an important therapy for advanced heart failure, with more than 18,000 continuous flow devices implanted worldwide to date. These devices significantly improve survival and quality of life and should be considered in every patient with end-stage heart failure with reduced ejection fraction who has no other life-limiting diseases. All candidates for device implantation should undergo a thorough evaluation in order to identify those who could benefit from device implantation. Long-term management of ventricular assist device patients is challenging and requires knowledge of the characteristic complications with their unique clinical presentations. PMID:28785427

The interrelationship between the etiology of pleural effusion and the side of its occurrence has been a subject of clinical interest for many years. It has often been stated that pleural effusion caused by congestive heart failure tends to occur on the right side. However, some authors contended that such a side proclivity is not reliable. In the present study, the authors investigated the laterally of effusion caused by various cardiovascular diseases complicated by heart failure. We reviewed the chest X-ray films and clinical records of 68 patients with proven pleural effusion resulted from heart failure. 1. There were 34 men and 34 women with the age ranging from 10 to 84 years with the mean of 59. 2. The diagnoses were rheumatic heart disease (2 patients), coronary heart disease (10 patients), hypertensive heart disease (8 patients), mitral valvular disease (18 patients), aortic valvular disease (3 patients), and miscellaneous (27 patients). 3. 34 patients had unilateral pleural effusion, 25 and 9, right and left, respectively. Of the 34 patients with bilateral effusion, 13 patients had predominantly right-sided effusion, 5 patients had predominantly left-sided effusion and 16 patients had evenly distributed bilateral effusion. Thus, 55.8% of effusion was right-sided

Full Text Available Many quality-of-care and risk prediction metrics rely on time to first rehospitalization even though heart failure (HF patients may undergo several repeat hospitalizations. The aim of this study is to compare repeat hospitalization models. Using a population-based cohort of 40,667 patients, we examined both HF and all cause re-hospitalizations using up to five years of follow-up. Two models were examined: the gap-time model which estimates the adjusted time between hospitalizations and a multistate model which considered patients to be in one of four states; community-dwelling, in hospital for HF, in hospital for any reason, or dead. The transition probabilities and times were then modeled using patient characteristics and number of repeat hospitalizations. We found that during the five years of follow-up roughly half of the patients returned for a subsequent hospitalization for each repeat hospitalization. Additionally, we noted that the unadjusted time between hospitalizations was reduced ∼40% between each successive hospitalization. After adjustment each additional hospitalization was associated with a 28 day (95% CI: 22-35 reduction in time spent out of hospital. A similar pattern was seen when considering the four state model. A large proportion of patients had multiple repeat hospitalizations. Extending the gap between hospitalizations should be an important goal of treatment evaluation.

Left ventricular failure leads to circulatory failure which causes clinical symptoms and in which regional blood flow changes play an important role. An abnormality of systemic vasodilatation on exercise or on pharmacological intervention has been shown. This affects both the resistance and conductive vessels and is mainly functional, related to neurohormonal stimulation with a predominance of vasoconstrictive factors amongst which increased adrenergic tone probably plays an essential part. A modification of the endothelium-dependent response has recently been confirmed. The presence of structural vascular abnormalities (increase in parietal sodium and water concentrations, "remodelling" remains debatable in the human. These abnormalities have a common factor in their chronicity and take time to regress with medical treatment or after cardiac transplantation. Physical training seems to induce more marked and, above all, more rapid effects.

Background: Mibefradil was recently withdrawn from the market because of an unfavorable clinical profile in patients with chronic heart failure. Although drug interactions appear to play a role, other mechanisms such as proarrhythmia and autonomic deterioration could also be relevant. Chronic heart
To conclude, existing studies do not support the use of RAAS inhibitory treatments in right heart failure due to congenital heart disease but contain important limitations. Hence, there is a need for new well-designed trials including higher numbers of patients and validated endpoints to optimize and guide future treatment of this patient group.

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.

Mineralocorticoid-receptor antagonists improve the prognosis for patients with heart failure and a reduced left ventricular ejection fraction. We evaluated the effects of spironolactone in patients with heart failure and a preserved left ventricular ejection fraction. In this randomized, double-blind trial, we assigned 3445 patients with symptomatic heart failure and a left ventricular ejection fraction of 45% or more to receive either spironolactone (15 to 45 mg daily) or placebo. The primary outcome was a composite of death from cardiovascular causes, aborted cardiac arrest, or hospitalization for the management of heart failure. With a mean follow-up of 3.3 years, the primary outcome occurred in 320 of 1722 patients in the spironolactone group (18.6%) and 351 of 1723 patients in the placebo group (20.4%) (hazard ratio, 0.89; 95% confidence interval [CI], 0.77 to 1.04; P=0.14). Of the components of the primary outcome, only hospitalization for heart failure had a significantly lower incidence in the spironolactone group than in the placebo group (206 patients [12.0%] vs. 245 patients [14.2%]; hazard ratio, 0.83; 95% CI, 0.69 to 0.99, P=0.04). Neither total deaths nor hospitalizations for any reason were significantly reduced by spironolactone. Treatment with spironolactone was associated with increased serum creatinine levels and a doubling of the rate of hyperkalemia (18.7%, vs. 9.1% in the placebo group) but reduced hypokalemia. With frequent monitoring, there were no significant differences in the incidence of serious adverse events, a serum creatinine level of 3.0 mg per deciliter (265 μmol per liter) or higher, or dialysis. In patients with heart failure and a preserved ejection fraction, treatment with spironolactone did not significantly reduce the incidence of the primary composite outcome of death from cardiovascular causes, aborted cardiac arrest, or hospitalization for the management of heart failure.

OBJECTIVES: To determine the effects of congestive heart failure on a person's ability to walk at a steady pace while ambulating at a self-determined rate. SETTING: Beth Israel Hospital, Boston, a primary and tertiary teaching hospital, and a social activity center for elderly adults living in the community. PARTICIPANTS: Eleven elderly subjects (aged 70-93 years) with well compensated congestive heart failure (NY Heart Association class I or II), seven elderly subjects (aged 70-79 years) without congestive heart failure, and 10 healthy young adult subjects (aged 20-30 years). MEASUREMENTS: Subjects walked for 8 minutes on level ground at their own selected walking rate. Footswitches were used to measure the time between steps. Step rate (steps/minute) and step rate variability were calculated for the entire walking period, for 30 seconds during the first minute of the walk, for 30 seconds during the last minute of the walk, and for the 30-second period when each subject's step rate variability was minimal. Group means and 5% and 95% confidence intervals were computed. MAIN RESULTS: All measures of walking variability were significantly increased in the elderly subjects with congestive heart failure, intermediate in the elderly controls, and lowest in the young subjects. There was no overlap between the three groups using the minimal 30-second variability (elderly CHF vs elderly controls: P young: P < 0.001), and no overlap between elderly subjects with and without congestive heart failure when using the overall variability. For all four measures, there was no overlap in any of the confidence intervals, and all group means were significantly different (P < 0.05).

Objective: Systolic heart failure is a chronic condition with significant morbidity and mortality. Evidence based optimal medical therapy (OMT) has been shown to reduce mortality. Underuse of OMT due to multiple reasons has been a consistent problem. The study objective was to audit the use of OMT in patients with heart Failure. Study Design: Descriptive study. Place and Duration of study: This audit was carried out in AFIC-NIHD from April 2011- February 2012. Material and Methods: Seventy consecutive stage D heart failure patients were included in the study. The patients were assessed clinically by a cardiologist and all previous documentations, referral letters, prescriptions, and purchase receipts were reviewed. To identify any other medication patients might have been taking (which did not appear on the prescriptions) patients were asked to identify common medicine packs. The patients underwent a detailed clinical evaluation including history, physical examination. Relevant investigations were done. ACCF/AHA (American College of Cardiology Foundation / American Heart Association) and ESC (European Society of Cardiology) guidelines for the diagnosis and treatment of acute and chronic heart failure were taken as standard of care. Results: In our audit we found that a large proportion of patients who were at high risk as per the Seattle Heart Failure Model (SHFM) were not on OMT, only 4.3% of the patients were on beta blockers that have been shown to improve mortality in the large randomized clinical trials, 64.3% were not taking any beta blockers where as 55.7% were not on ACE inhibitors and adding the OMT greatly reduced their mortality risk. Conclusions: We concluded that a large proportion of patients were not on OMT despite not having any contraindication to such therapy. This deprives them of significant survival benefit. (author)

The current ability to predict readmissions in patients with heart failure is modest at best. It is unclear whether machine learning techniques that address higher dimensional, nonlinear relationships among variables would enhance prediction. We sought to compare the effectiveness of several machine learning algorithms for predicting readmissions. Using data from the Telemonitoring to Improve Heart Failure Outcomes trial, we compared the effectiveness of random forests, boosting, random forests combined hierarchically with support vector machines or logistic regression (LR), and Poisson regression against traditional LR to predict 30- and 180-day all-cause readmissions and readmissions because of heart failure. We randomly selected 50% of patients for a derivation set, and a validation set comprised the remaining patients, validated using 100 bootstrapped iterations. We compared C statistics for discrimination and distributions of observed outcomes in risk deciles for predictive range. In 30-day all-cause readmission prediction, the best performing machine learning model, random forests, provided a 17.8% improvement over LR (mean C statistics, 0.628 and 0.533, respectively). For readmissions because of heart failure, boosting improved the C statistic by 24.9% over LR (mean C statistic 0.678 and 0.543, respectively). For 30-day all-cause readmission, the observed readmission rates in the lowest and highest deciles of predicted risk with random forests (7.8% and 26.2%, respectively) showed a much wider separation than LR (14.2% and 16.4%, respectively). Machine learning methods improved the prediction of readmission after hospitalization for heart failure compared with LR and provided the greatest predictive range in observed readmission rates. © 2016 American Heart Association, Inc.

BACKGROUND: Despite progress in management of patients with heart failure (HF) these patients still have a poor prognosis. We tested the hypothesis whether the inflammatory biomarker YKL-40 alone or in combination with high-sensitivity C-reactive protein (hs-CRP) and/or N-terminal-pro-B natriuretic...... peptide (NT-proBNP) could be a new prognostic biomarker for all-cause mortality in patients with HF. METHODS AND RESULTS: A total of 717 of the 1000 patients with severe left ventricular systolic dysfunction included in the EchoCardiography and Heart Outcome Study were included in Denmark and had blood...... YKL-40 II to IV quartiles, respectively following multivariable adjustment for cardiovascular risk factors (age, left ventricular ejection fraction, gender, history of heart failure, ischemic heart disease, chronic pulmonary disease, diabetes mellitus, stroke, hypertension, NT-proBNP, hs...

Full Text Available Background: Circulatory system diseases are the first cause of death in Brazil. Objective: To analyze the evolution of mortality caused by heart failure, by ischemic heart diseases and by ill-defined causes, as well as their possible relations, in Brazil and in the geoeconomic regions of the country (North, Northeast, Center-West, South and Southeast, from 1996 to 2011. Methods: Data were obtained from DATASUS and death declaration records with codes I20 and I24 for acute ischemic diseases, I25 for chronic ischemic diseases, and I50 for heart failure, and codes in chapter XIII for ill-defined causes, according to geoeconomic regions of Brazil, from 1996 to 2011. Results: Mortality rates due to heart failure declined in Brazil and its regions, except for the North and the Northeast. Mortality rates due to acute ischemic heart diseases increased in the North and Northeast regions, especially from 2005 on; they remained stable in the Center-West region; and decreased in the South and in the Southeast. Mortality due to chronic ischemic heart diseases decreased in Brazil and in the Center-West, South and Southeast regions, and had little variation in the North and in the Northeast. The highest mortality rates due to ill-defined causes occurred in the Northeast until 2005. Conclusions: Mortality due to heart failure is decreasing in Brazil and in all of its geoeconomic regions. The temporal evolution of mortality caused by ischemic heart diseases was similar to that of heart failure. The decreasing number of deaths due to ill-defined causes may represent the improvement in the quality of information about mortality in Brazil. The evolution of acute ischemic heart diseases ranged according to regions, being possibly confused with the differential evolution of ill-defined causes.

The impact of lifelong exposure to myocardial dysfunction in populations with congenital heart disease (CHD) is becoming increasingly recognized. Most children born with CHD now reach adulthood and the long-term sequelae of treatment are contributing to substantial comorbidity. The combination of structural changes present at birth with changes resulting from cardiac surgery can result in heart failure. This article reports on the current state of knowledge on the epidemiology of heart failure in this patient population. Copyright © 2014 Elsevier Inc. All rights reserved.

Risk factors for first stroke are well established, but less is known about risk factors for recurrent stroke. In the present analysis, we aimed to assess the effect of heart rate and other possible predictors of stroke in a hypertensive population with previous stroke or transient ischemic attack (TIA). The Valsartan Antihypertensive Long-Term Use Evaluation trial was a multicentre, double-masked, randomized controlled, parallel group trial comparing the effects of an angiotensin receptor blocker (valsartan) and a calcium channel blocker (amlodipine) in patients with hypertension and high cardiovascular risk. We used Cox proportional hazard models to investigate the effect of baseline variables on the risk of stroke. Quadratic terms of the continuous variables were entered in the models to test for linearity. Of 15,245 patients included in the trial, 3014 had a previous stroke or TIA at baseline and were included in the present analysis. Stroke recurrence occurred in 239 patients (7.9%) during a median of 4.5 years of follow-up. Resting heart rate (per 10 beats per minute; hazard ratio [HR], 2.78; 95% confidence interval [CI], 1.18-6.58) and diabetes mellitus at baseline (HR, 1.47; 95% CI, 1.03-2.10) were significantly associated with an increased risk of stroke recurrence in the multivariable analysis. In high-risk, hypertensive patients with previous stroke or TIA, resting heart rate was the strongest predictor of recurrent stroke. Copyright © 2014 National Stroke Association.

Heart failure is one of the most common causes of hospitalization, hospital readmission and death. Patients with heart failure have many complications, with multiple co-existing diagnoses which result in polypharmacy. Following instructions provided by many physicians, medication adjustments based on changes in their symptoms are required. Behavioral adjustments concerning diet and exercise regime are recommended. Therefore, the patient plays a crucial role in the management of heart failure. To review the available studies on heart failure self-management, and investigate educational, behavioral and psychosocial strategies that plays an important role to improve patient self-management. A literature review was conducted based upon the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidance. The articles identified through an extensive search using PubMed and UpToDate from 1999 to 2016. Improved self-management will increase compliance, promote patient quality-of-life, advance clinical outcomes, reduce hospital re-admission and will decrease hospitalization costs.

Full Text Available Heart failure is a leading cause of morbidity and mortality with a prevalence that is rising throughout the world. Currently the pharmaceutical therapy of heart failure is mainly based on inhibition of the neurohumoral pathways that are activated secondary to the deterioration of cardiac function, and diuretics to alleviate the salt and water overload. With our increasing understanding of the pathophysiology of heart failure, it is now clear that the macroscopic and functional changes in the failing heart result from remodeling at the cellular, interstitial, and molecular levels. Therefore, emerging therapies propose to intervene directly in the remodeling process at the cellular and the molecular levels. Here, several experimental strategies that aim to correct the abnormalities in receptor and post-receptor-function, calcium handling, excitation and contraction coupling, signaling, and changes in the extra-cellular matrix in the failing heart will be discussed. These novel approaches, aiming to reverse the remodeling process at multiple levels, may appear on the clinical arena in the coming years.
Full Text Available Ferenc FollathUniversity Hospital Zürich, Steering Group Drug Therapy, Zürich, SwitzerlandAbstract: Acute heart failure (AHF is a major cause of hospitalizations. Severe dyspnea, pulmonary congestion and low cardiac output with peripheral vasoconstriction and renal hypoperfusion is a main form of clinical presentation. Most patients with acute worsening have a pre-existing decompensated chronic heart failure (ADCHF, but AHF may also occur as a first manifestation of a previously unknown heart disease. Myocardial ischemia, cardiac arrhythmias, non-compliance with medication and infections are frequent precipitating factors. Management of AHF depends on the underlying heart disease and cause of decompensation. In patients with ADCHF vasodilators and iv diuretics are first-line drugs for rapid reduction of dyspnea and congestion. In patients with signs of low cardiac output and oliguria, inotropic agents are also often administered to prevent further deterioration. Beta-adrenergic agents and phosphodiesterase inhibitors correct the hemodynamic disturbance, but may also induce arrhythmias and worsen myocardial ischemia. Inotropic therapy therefore remains controversial. A novel class of drugs, the calcium sensitizers, represent a new therapeutic option. Levosimendan was shown to improve myocardial contractility without increasing oxygen requirements and to produce peripheral and coronary vasodilation. Its therapeutic effects and tolerance have been tested in several trials. The present review focuses on the clinical pharmacology and therapeutic utility of levosimendan in patients with ADCHF.Keywords: acute heart failure, inotropic agents, calcium sensitizers, levosimendan

Full Text Available Heart failure (HF patients are older and frequently present with multiple co-morbidities. Co- morbidities worsen patient symptoms and may contribute to the progression of heart failure, increase mortality or limit the therapeutic response to treatment. Obstructive sleep apnoea (OSA affects 2–4% of the adult population world-wide and is associated with similar risk factors to HF, meaning it is a frequent finding in HF patients, including HFrEF, HFmrEF and HFpEF. OSA has consistently been shown to be associated with hypertension, coronary artery disease, arrhythmias, heart failure, and stroke. A thorough understanding of the diagnosis and treatment options of OSA is of paramount importance to the practising HF clinician. Patients may present to the HF specialist having been diagnosed by a formal sleep study or may be suspected of OSA because of symptoms of snoring, reports of obstructed breathing by the sleep partner or day-time sleepiness. The mainstay of treatment for OSA is a positive airway pressure mask which can be used in mild moderate and severe OSA. The need for therapy should be discussed with the patient and if the AHI is above 15/ hr then treatment is indicated to reduce this to below 15. This is a consensus recommendation and no adequately powered clinical trials have shown this improves either mortality or the risk of disease progression. Other options are discussed

Hydrotherapy (exercise in warm water) is considered to be a safe and beneficial method to use in the rehabilitation of stable heart failure patients, but there is little information on the effect of the increased venous return and enhanced preload in elderly patients with biventricular heart failure. We present a case of an elderly man who was recruited to participate in a hydrotherapy study. We compared echocardiographic data during warm water immersion with land measurements, and observed increases in stroke volume from 32 mL (land) to 42 mL (water), left ventricular ejection fraction from 22% to 24%, left ventricular systolic velocity from 4.8 cm/s to 5.0 cm/s and left atrioventricular plane displacement from 2.1 mm to 2.2 mm. By contrast, right ventricular systolic velocity decreased from 11.2 cm/s to 8.4 cm/s and right atrioventricular plane displacement from 8.1 mm to 4.7 mm. The tricuspid pressure gradient rose from 18 mmHg on land to 50 mmHg during warm water immersion. Thus, although left ventricular systolic function was relatively unaffected during warm water immersion, we observed a decrease in right ventricular function with an augmented right ventricular pressure. We recommend further investigations to observe the cardiac effect of warm water immersion on patients with biventricular systolic heart failure and at risk of elevated right ventricular pressure.

Many people may underappreciate the role of lifestyle in avoiding heart failure. We estimated whether greater adherence in middle age to American Heart Association's Life's Simple 7 guidelines—on smoking, body mass, physical activity, diet, cholesterol, blood pressure, and glucose—is associated with lower lifetime risk of heart failure and greater preservation of cardiac structure and function in old age. We studied the population-based Atherosclerosis Risk in Communities Study cohort of 13,462 adults ages 45-64 years in 1987-1989. From the 1987-1989 risk factor measurements, we created a Life's Simple 7 score (range 0-14, giving 2 points for ideal, 1 point for intermediate, and 0 points for poor components). We identified 2218 incident heart failure events using surveillance of hospital discharge and death codes through 2011. In addition, in 4855 participants free of clinical cardiovascular disease in 2011-2013, we performed echocardiography from which we quantified left ventricular hypertrophy and diastolic dysfunction. One in four participants (25.5%) developed heart failure through age 85 years. Yet, this lifetime heart failure risk was 14.4% for those with a middle-age Life's Simple 7 score of 10-14 (optimal), 26.8% for a score of 5-9 (average), and 48.6% for a score of 0-4 (inadequate). Among those with no clinical cardiovascular event, the prevalence of left ventricular hypertrophy in late life was approximately 40% as common, and diastolic dysfunction was approximately 60% as common, among those with an optimal middle-age Life's Simple 7 score, compared with an inadequate score. Greater achievement of American Heart Association's Life's Simple 7 in middle age is associated with a lower lifetime occurrence of heart failure and greater preservation of cardiac structure and function.

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.

Chronic heart failure (CHF) is an illness mostly affecting elderly people. In Germany CHF is one of the most common causes of death and at the same time one of the most common diagnosis in inpatient care. Due to the expected increase in life expectancy in the next few years experts predict a further step-up of the incidence. Against this background development of a national guideline on chronic heart failure was prioritised and accordingly the National Disease Management Guideline (NDMG) Chronic Heart Failure was developed by a multi- and interdisciplinary group. The guideline group comprised experts from all relevant scientific medical societies as well as a patient expert. The National Disease Management Guideline (NDMG) on Chronic Heart Failure aims at supporting patients and health care providers with respect to decisions on a specific health care problem by giving recommendations for actions. Recommendations are informed by the best available scientific evidence on this topic.Patients with CHF often suffer from multiple conditions. Due to this fact and the old age patients do have very complex and demanding health care needs. Thus accounting for co-morbidities is paramount in planning and providing health care for theses patients and communication between doctor and patient but also between all health care providers is crucial.Basic treatment strategies in chronic heart failure comprise management of risk factors and prognostic factors as well as appropriate consideration of co-morbidities accompanied by measures empowering patients in establishing a healthy life style and a self-dependant management of their illness.Psycho-social aspects have a very strong influence on patients' acceptance of the disease and their self-management. In addition they have a strong influence on therapy management of the treating physician thus they have to be addressed adequately during the consultation.The National Disease Management Guideline (NDMG) Chronic Heart Failure (CHF

A better understanding of the stroke risk factors in children with congenital heart disease (CHD) could inform stroke prevention strategies. We analyzed pediatric stroke associated with CHD in a large community-based case-control study. From 2.5 million children (aged hemorrhagic strokes and randomly selected age- and facility-matched stroke-free controls (3 per case). We determined exposure to CHD (diagnosed before stroke) and used conditional logistic regression to analyze stroke risk factors. CHD was identified in 15 of 412 cases (4%) versus 7 of 1236 controls (0.6%). Cases of childhood stroke (occurring between ages 29 days to 20 years) with CHD had 19-fold (odds ratio, 19; 95% confidence interval 4.2-83) increased stroke risk compared to controls. History of CHD surgery was associated with >30-fold (odds ratio, 31; confidence interval 4-241) increased risk of stroke in children with CHD when compared with controls. After excluding perioperative strokes, the history of CHD surgery still increased the childhood stroke risk (odds ratio, 13; confidence interval 1.5-114). The majority of children with stroke and CHD were outpatients at the time of stroke, and almost half the cases who underwent cardiac surgery had their stroke >5 years after the most recent procedure. An estimated 7% of ischemic and 2% of hemorrhagic childhood strokes in the population were attributable to CHD. CHD is an important childhood stroke risk factor. Children who undergo CHD surgery remain at elevated risk outside the perioperative period and would benefit from optimized long-term stroke prevention strategies. © 2014 American Heart Association, Inc.
Full Text Available Pediatric heart failure represents an important cause of morbidity and mortality in childhood. Currently, there are well-established guidelines for the management of heart failure in the adult population, but an equivalent consensus in children is lacking. In the clinical setting, ensuring an accurate diagnosis and defining etiology is essential to optimal treatment. Diuretics and angiotensin-converting enzyme inhibition are the first-line therapies, whereas beta-blockers and devices for electric therapy are less used in children than in adults. In the end-stage disease, heart transplantation is the best choice of treatment, while a left ventricular assist device can be used as a bridge to transplantation (due to the difficulties in finding organ donors, recovery (in the case of myocarditis, or destination therapy (for patients with systemic disease.

It can induce and promote the atherosclerotic process by means of several mechanisms involving endothelial shear stress and biochemical activities. Furthermore, elevated heart rate can directly increase heart ischemic conditions because of its skill in unbalancing demand/supply of oxygen and decreasing the diastolic period. Thus, many pharmacological treatments have been proposed in order to reduce heart rate and ameliorate the cardiovascular risk profile of individuals, especially those suffering from coronary artery diseases (CAD and chronic heart failure (CHF. Ivabradine is the first pure heart rate reductive drug approved and currently used in humans, created in order to selectively reduce sinus node function and to overcome the many side effects of similar pharmacological tools (ie, β-blockers or calcium channel antagonists. The aim of our review is to evaluate the role and the safety of this molecule on CAD and CHF therapeutic strategies.

Full Text Available OBJECTIVE: To identify predictors of low cardiac output and mortality in decompensated heart failure. INTRODUCTION: Introduction: Patients with decompensated heart failure have a high mortality rate, especially those patients with low cardiac output. However, this clinical presentation is uncommon, and its management is controversial. METHODS: We studied a cohort of 452 patients hospitalized with decompensated heart failure with an ejection fraction of 60 years, and 64.6% were men. Low cardiac output was present in 281 (63% patients on admission. Chagas disease was the cause of heart failure in 92 (20.4% patients who had higher B type natriuretic peptide levels (1,978.38 vs. 1,697.64 pg/mL; P = 0.015. Predictors of low cardiac output were Chagas disease (RR: 3.655, P<0.001, lower ejection fraction (RR: 2.414, P<0.001, hyponatremia (RR: 1.618, P = 0.036, and renal dysfunction (RR: 1.916, P = 0.007. Elderly patients were inversely associated with low cardiac output (RR: 0.436, P = 0.001. Predictors of mortality were Chagas disease (RR: 2.286, P<0.001, ischemic etiology (RR: 1.449, P = 0.035, and low cardiac output (RR: 1.419, P = 0.047. CONCLUSIONS: In severe decompensated heart failure, predictors of low cardiac output are Chagas disease, lower ejection fraction, hyponatremia, and renal dysfunction. Additionally, Chagas disease patients have higher B type natriuretic peptide levels and a worse prognosis independent of lower ejection fraction.

The nurse's role as educator has become very crucial in heart failure management; thus, nurses must be adequately prepared to undertake this task. The main objective of the study was to estimate the level of Cypriot nurses' knowledge on basic heart failure self-care principles. A questionnaire measuring knowledge on heart failure self-care principles was administered among cardiology nurses working in five public urban hospitals of Cyprus. Data were analysed by using descriptive statistics, t-test and analysis of variance for categorical variables (such as gender and working setting) and correlation tests (Pearson's) plus simple linear regression for continuous variables (such as working experience). Participants were 143 nurses. The mean heart failure self-care knowledge score was 13.57/20 (SD 2.33). Gender, hospital and cardiac clinical experience do not significantly affect scoring. Significant difference in the knowledge score was observed among critical care, cardiology and medical unit nurses (f=4.1, p=0.018). Post hoc analysis showed that this significant difference originated from the comparison of critical care nurses with cardiology unit nurses (14.1, SD 2.3 vs. 13.0, SD 2.1 respectively). Correlation and linear regression analyses yielded only weak negative correlation between correct scoring and duration of nursing practice (r=-0.262, p=0.002), with 6% of the total variation in scoring being explained by this relationship. Results are consistent with previous findings and it is thus under question whether cardiology nurses are properly educating their heart failure patients. Consequently, there is an urgent need for nurses to update their knowledge and enhance their educational skills.

Abstract Objective: to describe self-care behavior and its associated factors in a sample of heart failure Brazilian patients. Method: descriptive cross-sectional study with non-probabilistic sample of 116 ambulatory patients undergoing heart failure treatment. Self-care was evaluated using the Self-Care of Heart Failure Index, (scores ≥70 points=appropriate self-care). Association tests were applied, considering a descriptive level of 0.05. Results: the mean age of participants was 57.7 (SD =11.3) years; 54.3% were male; the mean schooling was 5.5 (SD = 4.0) years; and 74.1% had functional class II-III. The mean scores on the subscales of the Self-Care of Heart Failure Index indicated inappropriate self-care (self-care maintenance: 53.2 (SD =14.3), selfcare management: 50.0 (SD = 20.3) and self-care confidence: 52.6 (SD=22.7)) and it was found low frequencies of participants with appropriate self-care (self-care maintenance, 6.9%), self-care management (14.7%) and self-care confidence (19%). Higher scores of the Self-Care of Heart Failure Index were associated with: reduced left ventricular ejection fraction (p=0.001), longer time of experience with the disease (p=0.05) and joint monitoring by physician and nurse (p=0.007). Conclusion: investments are needed to improve the self-care behavior and the nursing can play a relevant role in this improvement. PMID:26444158

The prognostic value of peak VO2 and VE/VCO2 slope measured during cardiopulmonary exercise (CPX) testing has been well established in patients with advanced heart failure, but blood pressure response to exercise is less well characterized. We retrospectively studied 151 outpatients who underwent CPX testing as part of an advanced heart failure (HF) evaluation. The outcome of interest was failure of medical management, defined by death, cardiac transplantation, or left ventricular assist device placement. Patients were stratified into tertiles by change in systolic blood pressure (SBP) ( 20 mmHg were associated with an increased hazard (HR 1.046, 95% CI 1.018, 1.075). In conclusion, changes in SBP during CPX testing provide additional prognostic information above standard clinical variables. The peculiar increase in risk noted in those with a rise in SBP > 20 mmHg is less clear and needs to be investigated further.

Full Text Available Heart failure becomes main problem in cardiology because of increasing of heart failure patients, rehospitalization rate, morbidity, and mortality rate. The main causes of increasing heart failure problems are: (1 Successful treatment of acute myocardial infarction can be life saving, but its sequelae can cause heart failure. (2 Increasing life expectancy rate grows along with incidences of ageing related heart failure. (3 High prevalence of infection in Indonesia can cause rheumatic heart disease post Streptococcal beta hemolyticus infection, viral myocarditis, infective endocartitis, and tuberculoid pericarditis. (4 Many risk factors for coronary heart disease are often found in heart failure patients, for examples smoking, diabetes, hypercholesterolemia, hypertension, and obesity. Indonesia joined international multicentered registry in 2006. Acute Decompensated HEart failure REgistry is a web based international registry to record patient with acute decompensated heart failure treated in emergency room. It was found that heart failure patients in 5 big hospitals in Java and Bali island that joined this registry are younger, sicker and late to seek treatment. The median hospital length of stay was 7 days and in hospital mortality rate was 6.7%. The aim of this article is to give summary about essential things in diagnosing and treating heart failure patients. 3D (accurate diagnoses, evidence based drugs, and new devices are the most important but what to do and what not to do in dealing with heart failure is also useful for your daily practice.

Galectin-3 is an emerging biomarker playing an important, complex role in intracellular pathways of cardiovascular diseases and heart failure. We aimed therefore to investigate the predictive value of galectin-3 for incident cardiovascular disease and heart failure. Galectin-3 levels were measured in 8444 participants of the general population-based FINRISK 1997 cohort. Cox proportional hazards regression analyses, adjusting for traditional Framingham risk factors, prevalent valvular heart disease, eGFR (estimated glomerular filtration rate) as well as NT-proBNP, were used to examine the predictive power of galectin-3. Measurements of discrimination and reclassification using 10-fold cross-validation were performed to control for over-optimism. Cardiovascular death (CD), all-cause mortality, myocardial infarction (MI), ischemic stroke (hemorrhagic strokes were excluded) and heart failure (HF) were used as endpoints. During the follow-up of up to 15 years there were in total 1136 deaths from any cause, 383 cardiac deaths, 359 myocardial infarctions, 401 ischemic strokes and 641 cases of incident heart failure. Hazard ratios (HR) were statistically significant for all-cause mortality (1.12, p gender except for all-cause mortality. No significant improvements were observed in model discrimination or overall reclassification upon inclusion of galectin-3. Compared to NT-proBNP, the predictive power of galectin-3 was weaker but both remained significant, independently of each other. Galectin-3 levels were predictive for future cardiovascular events but improvements in discrimination and reclassifications were modest. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Objective: A reliable and easy-to-perform method for measuring right ventricular (RV) afterload is desirable when scheduling patients with systolic heart failure to undergo heart transplantation. The present study aimed to investigate the accuracy of echocardiographically-derived pulmonary arterial elastance as a measurement of pulmonary vascular resistance by comparing it with invasive measures. Methods: Thirty-one patients with moderate to severe systolic heart failure, including 22 (71%) male patients, with a mean age of 41.16±15.9 years were enrolled in the study. Right heart catheterization and comprehensive echocardiography during the first hour after completion of cardiac catheterization were performed in all the patients. The pulmonary artery elastance was estimated using the ratio of end-systolic pressure (Pes) over the stroke volume (SV) by both cardiac catheterization [Ea (PV)-C] and echocardiography [Ea (PV)-E]. Results: The mean Ea (PV)-C and Ea (PV)-E were estimated to be 0.73±0.49 mm Hg/mL and 0.67±0.44 mm Hg/mL, respectively. There was a significant relation between Ea (PV)-E and Ea (PV)-C (r=0.897, pechocardiography and catheterization methods for estimating Ea (PV), investigated by the Bland-Altman method, showed a mean bias of -0.06, with 95% limits of agreement from -0.36 mm Hg/mL to 0.48 mm Hg/mL. Conclusion: Doppler echocardiography is an easy, non-invasive, and inexpensive method for measuring pulmonary arterial elastance, which provides accurate and reliable estimation of RV afterload in patients with systolic heart failure.

Cardiopoiesis is a conditioning programme that aims to upgrade the cardioregenerative aptitude of patient-derived stem cells through lineage specification. Cardiopoietic stem cells tested initially for feasibility and safety exhibited signs of clinical benefit in patients with ischaemic heart failure (HF) warranting definitive evaluation. Accordingly, CHART-1 is designed as a large randomized, sham-controlled multicentre study aimed to validate cardiopoietic stem cell therapy. Patients (n = 240) with chronic HF secondary to ischaemic heart disease, reduced LVEF (Heart Failure Questionnaire score, 6 min walk test, LV end-systolic volume, and LVEF at 9 months. The secondary efficacy endpoint is the time to cardiovascular death or worsening HF at 12 months. Safety endpoints include mortality, readmissions, aborted sudden deaths, and serious adverse events at 12 and 24 months. The CHART-1 clinical trial is powered to examine the therapeutic impact of lineage-directed stem cells as a strategy to achieve cardiac regeneration in HF populations. On completion, CHART-1 will offer a definitive evaluation of the efficacy and safety of cardiopoietic stem cells in the treatment of chronic ischaemic HF.

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.

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.

BACKGROUND: Dronedarone is a novel antiarrhythmic drug with electrophysiological properties that are similar to those of amiodarone, but it does not contain iodine and thus does not cause iodine-related adverse reactions. Therefore, it may be of value in the treatment of patients with heart failu...... with dronedarone was associated with increased early mortality related to the worsening of heart failure. (ClinicalTrials.gov number, NCT00543699.)...... mortality was predominantly related to worsening of heart failure--10 deaths in the dronedarone group and 2 in the placebo group. The primary end point did not differ significantly between the two groups; there were 53 events in the dronedarone group (17.1%) and 40 events in the placebo group (12.......6%) (hazard ratio, 1.38; 95% CI, 0.92 to 2.09; P=0.12). More increases in the creatinine concentration were reported as serious adverse events in the dronedarone group than in the placebo group. CONCLUSIONS: In patients with severe heart failure and left ventricular systolic dysfunction, treatment...

This study investigated annual medical costs using real-world data focusing on acute heart failure. The data were retrospectively collected from six tertiary hospitals in South Korea. Overall, 330 patients who were hospitalized for acute heart failure between January 2011 and July 2012 were selected. Data were collected on their follow-up medical visits for 1 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. Annual per patient medical costs were estimated according to the type of medical services, and factors contributing to the costs using Gamma Generalized Linear Models (GLM) with log link were analyzed. 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 1 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 1 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 under-estimated. It was 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.

The increased incidence and prevalence of congestive heart failure place a high priority on novel treatment strategies. Left ventricular ejection fraction remains the single most valuable measurement providing both diagnostic and prognostic insights. The most systematic approach to heart failure involves an objective assessment of functional disability, to include exercise tests such as a 6-minute walk under standardized conditions. Left ventricular dysfunction incites a host of neurohumoral compensations that are of fundamental importance in the heart failure syndrome expression. Both vasoconstrictor and vasodilator neurohormones are stimulated and provide new therapeutic opportunities. The therapeutic approach to heart failure begins with a strong emphasis on prevention, patient education, and self-participation in therapy with respect to both its monitoring and adjustment. Diuretics remain a mainstay of therapy but, in the face of severe heart failure, may become ineffectual, requiring constant infusion of loop-active diuretics, combination diuretics, or diuretics in association with concomitant low-dose dopamine infusion. Vasodilator therapy has been an important advance: combination hydralazine and nitrate therapy was initially shown to be efficacious in improving survival, and more recently, angiotensin-converting enzyme (ACE) inhibitors, in the form of enalapril, have shown incremental benefit on survival over this combination. Interestingly, there is now evidence from both SOLVD and SAVE to demonstrate an unexpected and, as yet, unexplained reduction in the frequency of both unstable angina and myocardial infarction. Although, on balance, the weight of evidence concerning the long-term efficacy of inotropic agents has been disappointing, especially as it relates to their unfavorable effects on survival, recent information on vesnarinone, an agent with a complex and diversified mechanism of action, suggests that with appropriate doses, improved symptoms and
Full Text Available We report a full-term female neonate who presented with respiratory distress and severe heart failure soon after birth. Heart failure secondary to perinatal infection was initially suspected. Subsequent echocardiography revealed aortic runoff, which led to consideration of an intracranial vascular abnormality. Ultrasound and magnetic resonance imaging of the brain confirmed a diagnosis of vein of Galen aneurismal malformation (VGAM. Endovascular coil embolization of the vascular anomaly was performed, resulting in improvement of heart failure. VGAM should be considered in the differential diagnosis of neonatal congestive heart failure with a structurally normal heart. Urgent endovascular embolization and aggressive medical treatment of heart failure improve prognosis in neonatal VGAM.

Cardiac dyssynchrony refers to disparity in cardiac wall motion, a serious consequence of myocardial infarction associated with poor outcome. Infarct-induced scar is refractory to device-based cardiac resynchronization therapy, which relies on viable tissue. Leveraging the prospect of structural and functional regeneration, reparative resynchronization has emerged as a potentially achievable strategy. In proof-of-concept studies, stem-cell therapy eliminates contractile deficit originating from infarcted regions and secures long-term synchronization with tissue repair. Limited clinical experience suggests benefit of cell interventions in acute and chronic ischemic heart disease as adjuvant to standard of care. A regenerative resynchronization option for dyssynchronous heart failure thus merits validation.

Full Text Available Chronic Heart Failure (CHF is a debilitating illness commonly encountered in primary care. Its prevalence in developing countries is rising as a result of an ageing population, and an escalating epidemic of hypertension, type 2 diabetes and coronary heart disease. CHF can be specifically diagnosed as Heart Failure with Reduced Systolic Function (HF-RSF or Heart Failure with Preserved Systolic Function (HF-PSF. This paper illustrates a common presentation of HF-PSF in primary care; and critically appraises the evidence in support of its diagnosis, prognosis and management. Regardless of the specific diagnosis, long term management of CHF is intricate as it involves a complex interplay between medical, psychosocial, and behavioural factors. Hence, there is a pressing need for a multidisciplinary team management of CHF in primary care, and this usually takes place within the broader context of an integrated chronic disease management programme. Primary care physicians are ideally suited to lead multidisciplinary teams to ensure better co-ordination, continuity and quality of care is delivered for patients with chronic conditions across time and settings. Given the rising epidemic of cardiovascular risk factors in the Malaysian population, preventive strategies at the primary care level are likely to offer the greatest promise for reducing the growing burden of CHF.

Approximately 5.7 million people in the United States have a diagnosis of heart failure, and more than 3,100 patients are awaiting a heart transplant. A temporary total artificial heart (TAH-t, SynCardia Systems Inc, Tucson, Arizona) is approved by the US Food and Drug Administration (FDA) as a bridge to transplant in patients at risk of dying of biventricular heart failure. Currently, TAH-t recipients awaiting transplant are hospital-bound and attached to a large pneumatic driver. In 2010, the FDA gave conditional approval for an Investigational Device Exemption clinical study of the portable Freedom driver (SynCardia). This case report describes a 61-year-old man admitted with acute decompensated heart failure, which progressively worsened, eventually requiring implantation of a TAH-t. Following stabilization, the patient was switched to the Freedom driver. After the patient and his wife proved competence in managing the device, they were able to take several daylong excursions outside the hospital. The patient considered discharge from the hospital while awaiting a transplant but ultimately received a heart transplant while still an inpatient. Higher rates of survival to transplant have already been proved with the TAH-t. Potential benefits for the portable Freedom driver include increased mobility, decreased cost, and improved quality of life.

Heart failure (HF) is an epidemic in healthcare worldwide, including Asia. It appears that HF will become more serious in the near future, with the epidemiological transition and ageing of the population. However, in contrast to Western countries, information on HF epidemiology is still limited in Asia, particularly in South Asia. In this review, we will briefly summarize available information regarding the current and future burden of HF in Asia, which indicates the importance of both primary prevention of underlying diseases of HF and secondary prevention, including management of ischaemic HF, HF with preserved EF, and HF in the elderly. © 2015 The Authors European Journal of Heart Failure © 2015 European Society of Cardiology.

Cardiovascular imaging is key for the assessment of patients with heart failure. Today, cardiovascular magnetic resonance imaging plays an established role in the assessment of patients with suspected and confirmed heart failure syndromes, in particular identifying aetiology. Its role in informing prognosis and guiding decisions around therapy are evolving. Key strengths include its accuracy; reproducibility; unrestricted field of view; lack of radiation; multiple abilities to characterise myocardial tissue, thrombus and scar; as well as unparalleled assessment of left and right ventricular volumes. T2* has an established role in the assessment and follow-up of iron overload cardiomyopathy and a role for T1 in specific therapies for cardiac amyloid and Anderson–Fabry disease is emerging.

Improved treatments for heart failure patients will require the development of novel therapeutic strategies that target basal disease mechanisms. Disrupted cardiomyocyte Ca2+ homeostasis is recognized as a major contributor to the heart failure phenotype, as it plays a key role in systolic and diastolic dysfunction, arrhythmogenesis, and hypertrophy and apoptosis signaling. In this review, we outline existing knowledge of the involvement of Ca2+ homeostasis in these deficits, and identify four promising targets for therapeutic intervention: the sarcoplasmic reticulum Ca2+ ATPase, the Na+-Ca2+ exchanger, the ryanodine receptor, and t-tubule structure. We discuss experimental data indicating the applicability of these targets that has led to recent and ongoing clinical trials, and suggest future therapeutic approaches. PMID:25483944

The aim of this study was to investigate the relationship between gene Period3 (Per3) variable number tandem repeat (VNTR) polymorphism and chronic heart failure (CHF). The study subjects (372 patients of Caucasian origin with CHF and 332 healthy controls) were genotyped for Per3 VNTR polymorphism using an allele-specific PCR. No significant differences in genotype or Per3 VNTR allele frequencies were found between CHF cases and controls (Pg=0.30, Pa=0.52). No significant differences were uncovered either between CHF cases according to etiology (DCMP vs. IHD; Pg=0.87, Pa=0.91). In the multivariate regression modeling, no predictive function of VNTR Per3 polymorphism on ejection fraction or NYHA class, hyperlipidaemia or type II diabetes risk was found. Per3 VNTR polymorphism is not a major risk factor for chronic heart failure or a factor modulating the severity of the CHF in this population.

Autoantibodies directed against endogenous proteins including contractile proteins and endothelial antigens are frequently detected in patients with heart failure and after heart transplantation. There is evidence that these autoantibodies contribute to cardiac dysfunction and correlate with clinical outcomes. Currently, autoantibodies are detected in patient sera using individual ELISA assays (one for each antigen). Thus, screening for many individual autoantibodies is laborious and consumes a large amount of patient sample. To better capture the broad-scale antibody reactivities that occur in heart failure and post-transplant, we developed a custom antigen microarray technique that can simultaneously measure IgM and IgG reactivities against 64 unique antigens using just five microliters of patient serum. We first demonstrated that our antigen microarray technique displayed enhanced sensitivity to detect autoantibodies compared to the traditional ELISA method. We then piloted this technique using two sets of samples that were obtained at our institution. In the first retrospective study, we profiled pre-transplant sera from 24 heart failure patients who subsequently received heart transplants. We identified 8 antibody reactivities that were higher in patients who developed cellular rejection (2 or more episodes of grade 2R rejection in first year after transplant as defined by revised criteria from the International Society for Heart and Lung Transplantation) compared with those who did have not have rejection episodes. In a second retrospective study with 31 patients, we identified 7 IgM reactivities that were higher in heart transplant recipients who developed antibody-mediated rejection (AMR) compared with control recipients, and in time course studies, these reactivities appeared prior to overt graft dysfunction. In conclusion, we demonstrated that the autoantibody microarray technique outperforms traditional ELISAs as it uses less patient sample, has

The goal of this paper is to provide a summary of the new recommendations in the most recent 2017 ACC/AHA/HFSA Focused Update of the 2013 ACCF/AHA Guideline for the Management of Heart Failure: A Report of the American College of Cardiology/American Heart Association Task Force on Clinical Practice Guidelines and the Heart Failure Society of America. The intent is to provide the background and the supporting evidence for the recommendations and to provide practical guidance for management strategies in treatment of heart failure patients. In the 2017 ACC/AHA/HFSA Focused Update of HF guidelines, important additions include new information on biomarkers, specifically on the topics of the diagnostic, prognostic role of natriuretic peptides in heart failure, and the role of natriuretic peptides in screening in patients high risk for HF and prevention of HF. There are important recommendations for treatment of patients with HF with reduced EF (HFrEF), including the beneficial role of angiotensin receptor blocker and neprilysin inhibition (ARNI) treatment in reducing outcomes including mortality, ivabradine in reducing heart failure hospitalizations in stable HFrEF patients with sinus rhythm and heart rate ≥ 70 bpm despite β-blockers. In patients with HF with preserved EF (HFpEF), though there are no studies demonstrating survival benefit, potential benefit with aldosterone antagonism in reducing HF hospitalizations is noted. In treatment of comorbidities, optimization of blood pressure control to less than 130 mmHg is recommended in hypertensive patients to prevent HF or in patients with hypertension and HFrEF or HFpEF. In addition to recognition on the potential role of treatment of iron deficiency anemia to improve symptoms and functional capacity, caution against use of adaptive servo-ventilation in patients with HFrEF and central sleep apnea and against use of erythropoietin stimulating agents in patients with HFrEF is provided. There are new treatment
Full Text Available Objectives: 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. 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
Full Text Available Abstract Background Previous studies showing a strong relationship between Cheyne-Stokes respiration and the severity of left ventricular systolic dysfunction have usually been done in selected patient populations with lower age and a higher proportion of males than the "typical" in-hospital patient with heart failure. The purpose of the present study was test the strength of this relationship in unselected patients admitted to hospital due to decompensated chronic heart failure. Methods We evaluated 191 patients (32% women, mean age 73 years, ready for discharge from the heart failure unit in the University Hospital of Malmö, Sweden. The patients underwent echocardiography for determination of left ventricular ejection fraction and left ventricular inner diastolic diameter. A respiratory investigation during sleep was performed the last night before discharge. Results We found that 66% of the patients had Cheyne-Stokes respiration more than 10% of the total recording time. Only 7 (3.6% of the patients had predominantly obstructive apnoeas. There was a significant but very weak relationship between left ventricular ejection fraction and left ventricular inner diastolic diameter on one hand and Cheyne-Stokes respiration on the other. Age was a stronger determinant of Cheyne-Stokes respiration than any of the cardiac or other clinical variables. Conclusion Although presence of Cheyne-Stokes respiration indicates left ventricular dysfunction, its severity seems only weakly related to the severity of heart failure. Age was found to be a stronger determinant, which may reflect the underlying age-dependency found also in healthy subjects. Due to age restrictions or other selection criteria, the importance of age may have been underestimated in many previous studies on factors associated with Cheyne-Stokes respiration.

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.

Abstract Aims Remote management of heart failure using implantable electronic devices (REM-HF) aimed to assess the clinical and cost-effectiveness of remote monitoring (RM) of heart failure in patients with cardiac implanted electronic devices (CIEDs). Methods and results Between 29 September 2011 and 31 March 2014, we randomly assigned 1650 patients with heart failure and a CIED to active RM or usual care (UC). The active RM pathway included formalized remote follow-up protocols, and UC was standard practice in nine recruiting centres in England. The primary endpoint in the time to event analysis was the 1st event of death from any cause or unplanned hospitalization for cardiovascular reasons. Secondary endpoints included death from any cause, death from cardiovascular reasons, death from cardiovascular reasons and unplanned cardiovascular hospitalization, unplanned cardiovascular hospitalization, and unplanned hospitalization. REM-HF is registered with ISRCTN (96536028). The mean age of the population was 70 years (range 23–98); 86% were male. Patients were followed for a median of 2.8 years (range 0–4.3 years) completing on 31 January 2016. Patient adherence was high with a drop out of 4.3% over the course of the study. The incidence of the primary endpoint did not differ significantly between active RM and UC groups, which occurred in 42.4 and 40.8% of patients, respectively [hazard ratio 1.01; 95% confidence interval (CI) 0.87–1.18; P = 0.87]. There were no significant differences between the two groups with respect to any of the secondary endpoints or the time to the primary endpoint components. Conclusion Among patients with heart failure and a CIED, RM using weekly downloads and a formalized follow up approach does not improve outcomes. PMID:28575235

Full Text Available The aging human population has emerged as a critically important factor in health care, not only due to the unique physiologic and pathologic processes associated with aging but also because of the evolution of medical and surgical therapies that have increased quality and quantity of life. Heart failure is a disease found most commonly among older populations in whom it is associated with high morbidity and mortality. Heart failure disproportionately affects the elderly, and it stands to reason that the most terminal stage, known as advanced heart failure (AHF, is more common among the elderly. Despite limited data, treatment options for AHF patients, including heart transplantation and left ventricular assist device (LVAD therapy, have demonstrated improved quality and quantity of life. Similarly, a well-structured palliative care program may offer symptom relief and social support without the need for high-risk surgical options. Furthermore, as the therapeutic window (risk/benefit ratio is narrower among elderly patients, the potential for positive outcomes from AHF options must be carefully evaluated together with patient-specific risks in the context of palliative care discussions. Therefore, the decision to leverage these options must be balanced with not only age, but also frailty, comorbidities, and cognition, functional, social and nutritional status to determine the right candidates for each therapy. This review strives to inform providers on the relevant considerations when leveraging AHF options among elderly patients. We conclude by providing a personalized model for care developed at a large tertiary care hospital that has performed more than 1,600 AHF procedures (870 heart transplants, 745 LVADs.

Central sleep apnoea occurs in about a third of patients with reduced systolic heart failure and is a marker of increased mortality. Such patients usually are older males with advanced heart failure (i.e., high pulmonary wedge pressure), often in atrial fibrillation, with evidence of hyperventilation (i.e., low PaCO2) in the absence of hypoxemia. Characteristically, ventilation waxes and wanes in a sinusoidal pattern, with mild hypoxemia, occurring in the lighter levels of sleep usually when supine. Snoring may also occur in central sleep apnoea, often at the peak of hyperventilation, sometimes contributing to the confusion or overlap with obstructive sleep apnoea. Central sleep apnoea is associated with orthopnoea, paroxysmal nocturnal dyspnoea and an oscillatory respiratory pattern with an incremental cardiopulmonary exercise study. Importantly, heart failure therapies (e.g., afterload reduction, diuresis, pacemakers, transplantation) attenuate central sleep apnoea. Night to night variability in severity of central sleep apnoea may occur with changes in patients' posture during sleep (less severe when sleeping on-side or upright). Crown Copyright © 2016.

Full Text Available Despite great advances in therapies observed during the last decades, heart failure (HF remained a major health problem in western countries. In order to further improve symptoms and survival in patients with heart failure, novel therapeutic strategies are needed. In some animal models of HF resveratrol (RES, it was able to prevent cardiac hypertrophy, contractile dysfunction, and remodeling. Several molecular mechanisms are thought to be involved in its protective effects, such as inhibition of prohypertrophic signaling molecules, improvement of myocardial Ca2+ handling, regulation of autophagy, and the reduction of oxidative stress and inflammation. In our present study, we wished to further examine the effects of RES on prosurvival (Akt-1, GSK-3β and stress signaling (p38-MAPK, ERK 1/2, and MKP-1 pathways, on oxidative stress (iNOS, COX-2 activity, and ROS formation, and ultimately on left ventricular function, hypertrophy and fibrosis in a murine, and isoproterenol- (ISO- induced postinfarction heart failure model. RES treatment improved left ventricle function, decreased interstitial fibrosis, cardiac hypertrophy, and the level of plasma BNP induced by ISO treatment. ISO also increased the activation of P38-MAPK, ERK1/2Thr183-Tyr185, COX-2, iNOS, and ROS formation and decreased the phosphorylation of Akt-1, GSK-3β, and MKP-1, which were favorably influenced by RES. According to our results, regulation of these pathways may also contribute to the beneficial effects of RES in HF.

Full Text Available Heart failure with preserved ejection fraction (HFpEF is characterized by signs and symptoms of heart failure in the presence of a normal left ventricular ejection fraction. Despite accounting for up to 50% of all clinical presentations of heart failure, the mechanisms implicated in HFpEF are poorly understood, thus precluding effective therapy. The pathophysiological heterogeneity in the HFpEF phenotype also contributes to this disease and likely to the absence of evidence-based therapies. Limited access to human samples and imperfect animal models that completely recapitulate the human HFpEF phenotype have impeded our understanding of the mechanistic underpinnings that exist in this disease. Aging and comorbidities such as atrial fibrillation, hypertension, diabetes and obesity, pulmonary hypertension, and renal dysfunction are highly associated with HFpEF, yet the relationship and contribution between them remains ill-defined. This review discusses some of the distinctive clinical features of HFpEF in association with these comorbidities and highlights the advantages and disadvantage of commonly used murine models used to study the HFpEF phenotype.

Acute heart failure (AHF) is a potentially life-threatening clinical syndrome, usually requiring hospital admission. Often the syndrome is characterized by congestion, and is associated with long hospital admissions and high risk of readmission and further healthcare expenditure. Despite a limited evidence-base, diuretics remain the first-line treatment for congestion. Loop diuretics are typically the first-line diuretic strategy with some evidence that initial treatment with continuous infusion or boluses of high-dose loop diuretic is superior to an initial lower dose strategy. In patients who have impaired responsiveness to diuretics, the addition of an oral thiazide or thiazide-like diuretic to induce sequential nephron blockade can be beneficial. The use of intravenous low-dose dopamine is no longer supported in heart failure patients with preserved systolic blood pressure and its use to assist diuresis in patients with low systolic blood pressures requires further study. Mechanical ultrafiltration has been used to treat patients with heart failure and fluid retention, but the evidence-base is not robust, and its place in clinical practice is yet to be established. Several novel pharmacological agents remain under investigation. Copyright © 2015 Cardiological Society of India. Published by Elsevier B.V. All rights reserved.
Full Text Available We present a case of feminizing adrenal carcinoma with severe elevation in serum estradiol and otherwise unexplained congestive heart failure with ventricular arrhythmia and review the literature on feminizing adrenal tumors and the potential relationship between estrogen and cardiac problems. A 54-year-old man presented with congestive heart failure and ventricular arrhythmia. Imaging revealed a large adrenal mass. Hormonal evaluation revealed a very high serum level of estradiol, elevated DHEA-sulfate and androstenedione, and lack of cortisol suppression on a low-dose overnight dexamethasone suppression test. The patient underwent a left adrenalectomy with subsequent normalization of serum estradiol. Surgical pathology examination established adrenocortical carcinoma MacFarlane stage II. Upon 15-month followup, the patient continued to have a normal serum estradiol level, his cardiac function was significantly improved, and he had no further episodes of ventricular arrhythmia. To the best of our knowledge, the serum estradiol level that was detected in our case is the highest that has been reported. Further, we hypothesize that the very high serum concentration of estradiol in our case may have played a role in his cardiac presentation with congestive heart failure and arrhythmia, particularly as these problems resolved with normalization of his serum estradiol level.
