Cardiac Natriuretic Peptides, Hypertension and Cardiovascular Risk

Prevalence of cardiovascular (CV) disease is increasing worldwide. One of the most important risk factors for CV disease is hypertension that is very often related to obesity and metabolic syndrome. The search for key mechanisms, linking high blood pressure (BP), glucose and lipid dysmetabolism together with higher CV risk and mortality, is attracting increasing attention. Cardiac natriuretic peptides (NPs), including ANP and BNP, may play a crucial role in maintaining CV homeostasis and cardiac health, given their impact not only on BP regulation, but also on glucose and lipid metabolism. The summa of all metabolic activities of cardiac NPs, together with their CV and sodium balance effects, may be very important in decreasing the overall CV risk. Therefore, in the next future, cardiac NPs system, with its two receptors and a neutralizing enzyme, might represent one of the main targets to treat these multiple related conditions and to reduce hypertension and metabolic-related CV risk.

Decreased cardiac mortality with nicorandil in patients with ischemic heart failure

BACKGROUND

Effective treatments in heart failure (HF) patients with ischemic etiology have not been fully established. Nicorandil, combination of nitrate component and sarcolemmal adenosine triphosphate-sensitive potassium channel opener, is a potent vasodilator of coronary and peripheral vessels and has been used as an antianginal agent. Therefore, we examined impacts of nicorandil on cardiac mortality in ischemic HF patients.

METHODS

Consecutive 334 HF patients with ischemic etiology were retrospectively registered and divided into 2 groups based on oral administration of nicorandil: nicorandil group (n = 116) and non-nicorandil group (n = 218). We retrospectively examined cardiac mortality.

RESULTS

In the Kaplan-Meier analysis (mean follow-up period 963 days), cardiac mortality was significantly lower in the nicorandil group than in the non-nicorandil group (11.2% vs. 19.7%, P = 0.032). In the Cox proportional hazard analysis, usage of nicorandil was a suppressor of cardiac mortality (hazard ratio 0.512, 95% confidence interval 0.275-0.953, P = 0.035), and this result was consistent in several subgroup analyses, such as left ventricular ejection fraction, percutaneous coronary intervention, coronary artery bypass graft, diabetes, β-blockers, and statins.

CONCLUSION

Nicorandil is potentially effective for reducing mortality in patients with ischemic heart failure.

TRIAL REGISTRATION

This was a retrospective study.

Acute Heart Failure Registry: Risk Assessment Model in Decompensated Heart Failure

Background

Heart failure (HF) is a highly prevalent syndrome. Although the long-term prognostic factors have been identified in chronic HF, this information is scarcer with respect to patients with acute HF. despite available data in the literature on long-term prognostic factors in chronic HF, data on acute HF patients are more scarce.

Objectives

To develop a predictor of unfavorable prognostic events in patients hospitalized for acute HF syndromes, and to characterize a group at higher risk regarding their clinical characteristics, treatment and outcomes.

Methods

cohort study of 600 patients admitted for acute HF, defined according to the European Society of Cardiology criteria. Primary endpoint for score derivation was defined as all-cause mortality and / or rehospitalization for HF at 12 months. For score validation, the following endpoints were used: all-cause mortality and / or readmission for HF at 6, 12 and 24 months. The exclusion criteria were: high output HF; patients with acute myocardial infraction, acute myocarditis, infectious endocarditis, pulmonary infection, pulmonary artery hypertension and severe mitral stenosis.

Results

505 patients were included, and prognostic predicting factors at 12 months were identified. One or two points were assigned according to the odds ratio (OR) obtained (p < 0.05). After the total score value was determined, a 4-point cut-off was determined for each ROC curve at 12 months. Two groups were formed according to the number of points, group A < 4 points, and group B = 4 points. Group B was composed of older patients, with higher number of comorbidities and predictors of the combined endpoint at 6, 12 and 24 months, as linearly represented in the survival curves (Log rank).

Conclusions

This risk score enabled the identification of a group with worse prognosis at 12 months.

Safety of the neprilysin/renin-angiotensin system inhibitor LCZ696

Objectives

The combined neprilysin/rennin-angiotensin system inhibitor sacubitril/valsartan (LCZ696) has shown its superiority over ACEI/ARB therapy. In view of the existing concern of its adverse effects, we aimed to provide evidence of the safety of the new drug.

Results

A total of 6 randomized trials with 11,821 subjects were included in this analysis. No significant differences were found in any adverse effects between LCZ696 and ACEI/ARB or placebo groups. LCZ696 significantly decreased the risks of serious adverse events and death compared with ACEI/ARB. LCZ696 also significantly decrease the risk of discontinuation of treatment for any adverse event no matter compared with ACEI/ARB or a placebo. LCZ696 significantly increased the risk of angioedema and dizziness, while it decreased the risk of renal dysfunction and bronchitis. There was no difference for hypotension, hyperkalemia, cough, upper respiratory tract inflammation, diarrhoea, back pain, nasopharyngitis, headache and influenza between the LCZ696 group and the ACEI/ARB group.

Materials and Methods

A meta-analysis of eligible studies that used LCZ696 in heart failure and hypertension was performed. Embase, PubMed and the Cochrane Library were searched for randomized controlled trials (RCTs) with data on any adverse effects, serious adverse events, discontinuation of treatment for any adverse event, death, angioedema, hypotension, hyperkalemia, and other adverse effects to perform this meta-analysis.

Conclusions

In addition to the beneficial effect of LCZ696 on end point events, the available evidences showed that LCZ696 was associated with less drug-risks than a placebo and ACEI/ARB.

Does an electronic cognitive aid have an effect on the management of severe gynaecological TURP syndrome? A prospective, randomised simulation study

Background

Lack of familiarity with the content of current guidelines is a major factor associated with non-compliance by clinicians. It is conceivable that cognitive aids with regularly updated medical content can guide clinicians’ task performance by evidence-based practices, even if they are unfamiliar with the actual guideline. Acute hyponatraemia as a consequence of TURP syndrome is a rare intraoperative event, and current practice guidelines have changed from slow correction to rapid correction of serum sodium levels. The primary objective of this study was to compare the management of a simulated severe gynaecological transurethral resection of the prostate (TURP) syndrome under spinal anaesthesia with either: an electronic cognitive aid, or with management from memory alone. The secondary objective was to assess the clinical relevance and participant perception of the usefulness of the cognitive aid.

Methods

Anaesthetic teams were allocated to control (no cognitive aid; n = 10) or intervention (cognitive aid provided; n = 10) groups. We identified eight evidence-based management tasks for severe TURP syndrome from current guidelines and subdivided them into acute heart failure (AHF)/pulmonary oedema tasks (5) and acute hyponatraemia tasks (3). Implementation of the treatment steps was measured by scoring task items in a binary fashion (yes/no). To assess whether or not the cognitive aid had prompted a treatment step, participants from the cognitive aid group were questioned during debriefing on every single treatment step. At the end of the simulation, session participants were asked to complete a survey.

Results

Teams in the cognitive aid group considered evidence-based treatment steps significantly more often than teams of the control group (96% vs. 50% for ‘AHF/pulmonary oedema’ p < 0.001; 79% vs. 12% for ‘acute hyponatraemia’ p < 0.001). Without the cognitive aid, performance would have been comparable across both groups. Nurses, trainees, and consultants derived equal benefit from the cognitive aid.

Conclusions

The cognitive aid improved the implementation of evidence-based practices in a simulated intraoperative scenario. Cognitive aids with current medical content could help to close the translational gap between guideline publication and implementation in acute patient care. It is important that the cognitive aid should be familiar, in a format that has been used in practice and training.

Organ dysfunction, injury and failure in acute heart failure: from pathophysiology to diagnosis and management. A review on behalf of the Acute Heart Failure Committee of the Heart Failure Association (HFA) of the European Society of Cardiology (ESC)

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

Clinical Characteristics and Outcome of Acute Heart Failure in Korea: Results from the Korean Acute Heart Failure Registry (KorAHF)

Background and Objectives

The burden of heart failure has increased in Korea. This registry aims to evaluate demographics, clinical characteristics, management, and long-term outcomes in patients hospitalized for acute heart failure (AHF).

Subjects and Methods

We prospectively enrolled a total of 5625 consecutive subjects hospitalized for AHF in one of 10 tertiary university hospitals from March 2011 to February 2014. Descriptive statistics were used to determine the baseline characteristics of the study population and to compare them with those from other registries.

Results

The mean age was 68.5±14.5 years, 53.2% were male, and 52.2% had de novo heart failure. The mean systolic and diastolic blood pressures were 131.2±30.3 mmHg and 78.6±18.8 mmHg at admission, respectively. The left ventricular ejection fraction was ≤40% in 60.5% of patients. Ischemia was the most frequent etiology (37.6%) and aggravating factor (26.3%). Angiotensin converting enzyme inhibitors/angiotensin receptor blockers, beta-blockers, and aldosterone antagonists were prescribed in 68.8%, 52.2%, and 46.6% of the patients at discharge, respectively. Compared with the previous registry performed in Korea a decade ago, extracorporeal membrane oxygenation (ECMO) and heart transplantation have been performed more frequently (ECMO 0.8% vs. 2.8%, heart transplantation 0.3% vs. 1.2%), and in-hospital mortality decreased from 7.6% to 4.8%. However, the total cost of hospital care increased by 40%, and one-year follow-up mortality remained high.

Conclusion

While the quality of acute clinical care and AHF-related outcomes have improved over the last decade, the long-term prognosis of heart failure is still poor in Korea. Therefore, additional research is needed to improve long-term outcomes and implement cost-effective care.

Heart Failure with Myocardial Recovery - The Patient Whose Heart Failure Has Improved: What Next?

In an important number of heart failure (HF) patients substantial or complete myocardial recovery occurs. In the strictest sense, myocardial recovery is a return to both normal structure and function of the heart. HF patients with myocardial recovery or recovered ejection fraction (EF; HFrecEF) are a distinct population of HF patients with different underlying etiologies, demographics, comorbidities, response to therapies and outcomes compared to HF patients with persistent reduced (HFrEF) or preserved ejection fraction (HFpEF). Improvement of left ventricular EF has been systematically linked to improved quality of life, lower rehospitalization rates and mortality. However, mortality and morbidity in HFrecEF patients remain higher than in the normal population. Also, persistent abnormalities in biomarker and gene expression profiles in these patients lends weight to the hypothesis that pathological processes are ongoing. Currently, there remains a lack of data to guide the management of HFrecEF patients. This review will discuss specific characteristics, pathophysiology, clinical implications and future needs for HFrecEF.

Effect of Ularitide on Cardiovascular Mortality in Acute Heart Failure

BACKGROUND

In patients with acute heart failure, early intervention with an intravenous vasodilator has been proposed as a therapeutic goal to reduce cardiac-wall stress and, potentially, myocardial injury, thereby favorably affecting patients' long-term prognosis.

METHODS

In this double-blind trial, we randomly assigned 2157 patients with acute heart failure to receive a continuous intravenous infusion of either ularitide at a dose of 15 ng per kilogram of body weight per minute or matching placebo for 48 hours, in addition to accepted therapy. Treatment was initiated a median of 6 hours after the initial clinical evaluation. The coprimary outcomes were death from cardiovascular causes during a median follow-up of 15 months and a hierarchical composite end point that evaluated the initial 48-hour clinical course.

RESULTS

Death from cardiovascular causes occurred in 236 patients in the ularitide group and 225 patients in the placebo group (21.7% vs. 21.0%; hazard ratio, 1.03; 96% confidence interval, 0.85 to 1.25; P=0.75). In the intention-to-treat analysis, there was no significant between-group difference with respect to the hierarchical composite outcome. The ularitide group had greater reductions in systolic blood pressure and in levels of N-terminal pro-brain natriuretic peptide than the placebo group. However, changes in cardiac troponin T levels during the infusion did not differ between the two groups in the 55% of patients with paired data.

CONCLUSIONS

In patients with acute heart failure, ularitide exerted favorable physiological effects (without affecting cardiac troponin levels), but short-term treatment did not affect a clinical composite end point or reduce long-term cardiovascular mortality.

A real world wearable cardioverter defibrillator experience - Very high appropriate shock rate in ischemic cardiomyopathy patients at a European single-center

BACKGROUND

The wearable cardioverter defibrillator (WCD) has emerged as a valuable tool to protect patients with increased risk of sudden cardiac death (SCD). We sought to characterize WCD patients and to analyze predictors of ventricular arrhythmia (VA) occurrence and WCD shock delivery.

METHODS AND RESULTS

One hundred fourteen patients with WCD use were included in the study. Indications were mainly ischemic cardiomyopathy (ICM; 31.6%), non-ICM (45.6%) and explantation of implantable cardioverter defibrillator due to device infection (11.4%). We observed sustained VA in 9.6% of the study population and 6.1% received an appropriate shock. VA occurred in 16.7% of ICM, 3.8% of non-ICM and 15.4% of patients with device infection.

CONCLUSIONS

Our data demonstrate a very high rate of sustained VA in patients at risk for SCD during WCD use. ICM patients, including those with recent MI, bore the highest risk.

Management of Patients with Atrial Fibrillation: Focus on Treatment Options

Atrial fibrillation (AF) is leading cardiac arrhythmia with important clinical implications. Its diagnosis is usually made on the basis on 12-lead ECG or 24-hour Holter monitoring. More and more clinical evidence supports diagnostic use of cardiac event recorders and cardiovascular implantable electronic devices (CIED). Treatment options in patients with atrial fibrillation are extensive and are based on chosen rhythm and/or rate control strategy. The use and selected contraindications to AF related pharmacotherapy, including anticoagulants are shown. Nonpharmacological treatments, comorbidities and risk factors control remain mainstay in the treatment of patients with AF. Electrical cardioversion consists important choice in rhythm control strategy. Much progress has been made in the field of catheter ablation and cardiac surgery methods. Left atrial appendage occlusion/closure may be beneficial in patients with AF. CIED are used with clinical benefits in both, rhythm and rate control. Pacemakers, implantable cardioverter-defibrillators and cardiac resynchronization therapy devices with different pacing modes have guaranteed place in the treatment of patients with AF. On the other hand, the concepts of permanent leadless cardiac pacing, atrial dyssynchrony syndrome treatment and His-bundle or para-Hisian pacing have been proposed. This review summarizes and discusses current and novel treatment options in patients with atrial fibrillation.

Epidemiology of heart failure with preserved ejection fraction

Heart failure (HF) with preserved ejection fraction (HFpEF) is a clinical syndrome associated with poor quality of life, substantial health-care resource utilization, and premature mortality. We summarize the current knowledge regarding the epidemiology of HFpEF with a focus on community-based studies relevant to quantifying the population burden of HFpEF. Current data regarding the prevalence and incidence of HFpEF in the community as well as associated conditions and risk factors, risk of morbidity and mortality after diagnosis, and quality of life are presented. In the community, approximately 50% of patients with HF have HFpEF. Although the age-specific incidence of HF is decreasing, this trend is less dramatic for HFpEF than for HF with reduced ejection fraction (HFrEF). The risk of HFpEF increases sharply with age, but hypertension, obesity, and coronary artery disease are additional risk factors. After adjusting for age and other risk factors, the risk of HFpEF is fairly similar in men and women, whereas the risk of HFrEF is much lower in women. Multimorbidity is common in both types of HF, but slightly more severe in HFpEF. A majority of deaths in patients with HFpEF are cardiovascular, but the proportion of noncardiovascular deaths is higher in HFpEF than HFrEF.

Causes of death in atrial fibrillation: Challenges and opportunities

Atrial fibrillation (AF) is an age-related arrhythmia associated with several co-morbidities and significant mortality. Most AF patients are in need of anticoagulation due to increased risk of stroke. Despite anticoagulation, AF patients still have a significant risk of death (about 5%/y). Approximately half of deaths in AF are due to heart-related causes (i.e., sudden death, heart failure, and myocardial infarction), one-third of deaths are due to non-vascular causes (i.e., cancer, respiratory diseases, and infections) and the remaining AF patients die from stroke or hemorrhage (about 6% each), or other causes. This review describes current situations related to causes of death in AF, the challenges in the management of AF (e.g., frequent presence of cardiovascular risk factors and co-morbidities, physicians adherence to clinical guidelines and patients adherence to cardiovascular medications in AF) as well as the opportunities for intervention.

Assessment of early treatment response by rapid cardiothoracic ultrasound in acute heart failure: Cardiac filling pressures, pulmonary congestion and mortality

Background:

It is unclear how to optimally monitor acute heart failure (AHF) patients. We evaluated the timely interplay of cardiac filling pressures, brain natriuretic peptides (BNPs), lung ultrasound (LUS) and symptoms during AHF treatment.

Methods:

We enrolled 60 patients who had been hospitalised for AHF. Patients were examined with a rapid cardiothoracic ultrasound (CaTUS) protocol, combining LUS and focused echocardiographic evaluation of cardiac filling pressures (i.e. medial E/e’ and inferior vena cava index [IVCi]). CaTUS was done at 0, 12, 24 and 48 hours (±3 hours) and on the day of discharge, alongside clinical evaluation and laboratory samples. Patients free of congestion (B lines or pleural fluid) on LUS at discharge were categorised as responders, whereas the rest were categorised as non-responders. Improvement in congestion parameters was evaluated separately in these groups. The effect of congestion parameters on prognosis was also analysed.

Results:

Responders experienced a significantly larger decline in E/e’ (2.58 vs. 0.38, p = 0.037) and dyspnoea visual analogue scale (1–10) score (7.68 vs. 3.57, p = 0.007) during the first 12 hours of treatment, while IVCi and BNPs declined later without no such rapid initial decline. Among patients experiencing a >3 U decline in E/e’ during the first 12 hours of treatment, 18/21 were to become responders ( p < 0.001). LUS response was the only congestion parameter independently predicting both 6-month survival regarding all-cause mortality and the composite endpoint of all-cause mortality or rehospitalisation for AHF.

Conclusion:

E/e’ seemed like the most useful congestion parameter for monitoring early treatment response, predicting prognostically beneficial resolution of pulmonary congestion.

Early in-hospital variation of red blood cell distribution width predicts mortality in patients with acute heart failure

BACKGROUND

Some studies showed that the value of red blood cell distribution width (RDW) at admission may predict clinical outcomes in patients with acutely decompensated heart failure (ADHF). Therefore, this study was planned to investigate whether in-hospital variations of RDW may also predict mortality in this condition.

METHODS

The final study population consisted of 588 patients admitted to the local Emergency Department (ED), who were hospitalized for ADHF. The RDW was measured at ED admission and after 48h and 96h of hospital stay. In-hospital variations from admission value, expressed as absolute variation (DeltaRDW) or percent variation (Delta%RDW), were then correlated with 30- and 60-day mortality.

RESULTS

Overall, 87 (14.8%) and 118 (20.1%) patients with ADHF died at 30 or 60days of follow-up. Delta%RDW after 96h of hospital stay independently predicted 30-day mortality (odds ratio, 1.12; 95% CI, 1.07-1.18). An increase >1% of Delta%RDW after 96h of hospital stay independently predicted both 30-day (odds ratio, 2.86; 95% CI, 1.67-4.97) and 60-day (odds ratio, 3.06; 95% CI, 1.89-4.96) mortality. A similar trend was observed for DeltaRDW, since an increase after 96h of hospital stay was associated with a nearly 4-fold higher 30-day mortality (odds ratio, 3.65; 95% CI, 2.02-6.15).

CONCLUSION

Despite it remains unclear whether RDW is a real risk factor or an epiphenomenon in ADHF, these results suggest that more aggressive management may be advisable in ADHF patients with increasing anisocytosis during the first days of hospitalization.

Palliative Care in Heart Failure: What Triggers Specialist Consultation?

Heart failure (HF) continues to cause substantial death and suffering despite the availability of numerous medical, surgical, and technological therapeutic advancements. As a patient-centered holistic discipline focused on improving quality of life and decreasing anguish, palliative care (PC) has a crucial role in the care of HF patients that has been acknowledged by multiple international guidelines. PC can be provided by all members of the HF care team, including but not limited to practitioners with specialty PC training. Unfortunately, despite recommendations to routinely include PC techniques and providers in the care of HF patients, use of general PC strategies as well as expert PC consultation is limited by a dearth of evidence-based interventions in the HF population and knowledge as to when to initiate these interventions, uncertainty regarding patient desires, prognosis, and the respective roles of each member of the care team, and a general shortage of specialist PC providers. This review seeks to provide guidance as to when to employ the limited resource of specialist PC practitioners, in combination with services from other members of the care team, to best tend to HF patients as their disease progresses and eventually overcomes.

[Cardiac support and replacement systems]

In recent years, the widespread use of partial mechanical cardiac support and even temporary complete replacement of cardiac function has been established in many intensive care units in the treatment of refractory cardiogenic shock. There is a difference between partial left-ventricular assist devices (LVAD) and the possibility of complete heart (and lung) replacement by extra corporeal life support (ECLS). Despite the use of mechanical support devices, the mortality of cardiogenic shock remains high. The consideration of using percutaneous LVAD and ECLS in cardiogenic shock should be considered in refractory cardiogenic shock patients in addition to support by catecholamines and after early revascularization in acute coronary syndromes. However, there are no large randomized studies evaluating mechanical support systems with respect to outcome in cardiogenic shock patients. German and international guidelines do not recommend the routine use of mechanical support as a first-line treatment in cardiogenic shock patients and emphasize that their application should be restricted to patients with therapy refractory shock. In other cases of noninfarct-related cardiogenic shock (e. g., poisoning, myocarditis), ECLS use should be considered as bridging therapy. ECLS may also be considered in cardiopulmonary resuscitation which is termed E‑CPR. According to registry data, E‑CPR may reduce mortality in selected patients. A possible application of ECLS is severe accidental hypothermia with cardiac arrest despite limited data. In these rare cases, early ECLS should be considered for rewarming and stabilization.

The Notch Ligands DLL1 and Periostin Are Associated with Symptom Severity and Diastolic Function in Dilated Cardiomyopathy

In dilated cardiomyopathy (DCM), adverse myocardial remodeling is essential, potentially involving Notch signaling. We hypothesized that secreted Notch ligands would be dysregulated in DCM. We measured plasma levels of the canonical Delta-like Notch ligand 1 (DLL1) and non-canonical Notch ligands Delta-like 1 homologue (DLK1) and periostin (POSN) in 102 DCM patients and 32 matched controls. Myocardial mRNA and protein levels of DLL1, DLK1, and POSN were measured in 25 explanted hearts. Our main findings were: (i) Circulating levels of DLL1 and POSN were higher in patients with severe DCM and correlated with the degree of diastolic dysfunction and (ii) right ventricular tissue expressions of DLL1, DLK1, and POSN were oppositely associated with cardiac function indices, as high DLL1 and DLK1 expression corresponded to more preserved and high POSN expression to more deteriorated cardiac function. DLL1, DLK1, and POSN are dysregulated in end-stage DCM, possibly mediating different effects on cardiac function.

Performance of AHEAD Score in an Asian Cohort of Acute Heart Failure With Either Preserved or Reduced Left Ventricular Systolic Function

Background

AHEAD (A: atrial fibrillation; H: hemoglobin; E: elderly; A: abnormal renal parameters; D: diabetes mellitus) score has been related to clinical outcomes of acute heart failure. However, the prognostic value of the AHEAD score in acute heart failure patients with either reduced or preserved left ventricular ejection fraction (HFrEF and HFpEF) remain to be elucidated.

Methods and Results

The study population consisted of 2143 patients (age 77±12 years, 68% men, 38% HFrEF) hospitalized primarily for acute heart failure with a median follow‐up of 23.75 months. The performance of the AHEAD score (atrial fibrillation, hemoglobin <13 mg/dL for men and 12 mg/dL for women, age >70 years, creatinine >130 μmol/L, and diabetes mellitus) was evaluated by Cox's regression analysis for predicting cardiovascular and all‐cause mortality. The mean AHEAD scores were 2.7±1.2 in the total study population, 2.6±1.3 in the HFrEF group, and 2.7±1.1 in the HFpEF group. After accounting for sex, sodium, uric acid, and medications, the AHEAD score remained significantly associated with all‐cause and cardiovascular mortality (hazard ratio and 95% CI: 1.49, 1.38–1.60 and 1.48, 1.33–1.64), respectively. The associations of AHEAD score with mortality remained significant in the subgroups of HFrEF (1.63, 1.47–1.82) and HFpEF (1.34, 1.22–1.48). Moreover, when we calculated a new AHEAD‐U score by considering uric acid (>8.6 mg/dL) in addition to the AHEAD score, the net reclassification was improved by 19.7% and 20.1% for predicting all‐cause and cardiovascular mortality, respectively.

Conclusions

The AHEAD score was useful in predicting long‐term mortality in the Asian acute heart failure cohort with either HFrEF or HFpEF. The new AHEAD‐U score may further improve risk stratification.

Prognostic impact of diastolic dysfunction in systolic heart failure-A cross-project analysis from the German Competence Network Heart Failure

BACKGROUND

We investigated the modifying role and prognostic importance of diastolic dysfunction (DD) in patients with heart failure and systolic dysfunction (SD).

HYPOTHESIS

The echocardiographic evaluation of diastolic function in patients with SD provides further prognostic information.

METHODS

From the German Competence Network Heart Failure, 1046 heart failure patients with reduced left ventricular ejection fraction (LVEF; <50%) were echocardiographically studied and followed for a median of 5 years. SD was subdivided into nonsevere (LVEF 36%-49%) and severe (LVEF ≤35%); DD was subdivided into nonsevere (E/E' <15) and severe (E/E' ≥15).

RESULTS

In general, severe SD was associated with higher hazard ratios (HRs; 2-fold to 3.5-fold) for all endpoints (all-cause death, cardiac death, cardiovascular hospitalization, duration of hospitalization). Patients with severe SD had a 2.5-fold risk of death (95% confidence interval [CI]: 1.84-3.47, P < 0.001), and patients with severe DD showed a 1.8-fold risk (95% CI: 1.17-2.61, P = 0.004). Furthermore, we observed a strong interaction of SD and DD: concomitant severe DD in patients with moderate SD increased risk substantially (HR: 1.73, 95% CI: 1.16-2.6, P = 0.007); by contrast, in patients with severe SD, additional presence of severe DD added little or no risk (HR for interaction: 0.5-1.2).

CONCLUSIONS

In heart failure patients with reduced LVEF, the evaluation of diastolic function provides additional prognostic information. Although severe SD generally increased the risk for all endpoints, the degree of DD and its impact as a prognostic marker for overall and cardiovascular mortality appeared of particular relevance in subjects with nonsevere SD.

Risk for Incident Heart Failure: A Subject-Level Meta-Analysis From the Heart "OMics" in AGEing (HOMAGE) Study

Background

To address the need for personalized prevention, we conducted a subject‐level meta‐analysis within the framework of the Heart “OMics” in AGEing (HOMAGE) study to develop a risk prediction model for heart failure (HF) based on routinely available clinical measurements.

Methods and Results

Three studies with elderly persons (Health Aging and Body Composition [Health ABC], Valutazione della PREvalenza di DIsfunzione Cardiaca asinTOmatica e di scompenso cardiaco [PREDICTOR], and Prospective Study of Pravastatin in the Elderly at Risk [PROSPER]) were included to develop the HF risk function, while a fourth study (Anglo‐Scandinavian Cardiac Outcomes Trial [ASCOT]) was used as a validation cohort. Time‐to‐event analysis was conducted using the Cox proportional hazard model. Incident HF was defined as HF hospitalization. The Cox regression model was evaluated for its discriminatory performance (area under the receiver operating characteristic curve) and calibration (Grønnesby‐Borgan χ² statistic). During a follow‐up of 3.5 years, 470 of 10 236 elderly persons (mean age, 74.5 years; 51.3% women) developed HF. Higher age, BMI, systolic blood pressure, heart rate, serum creatinine, smoking, diabetes mellitus, history of coronary artery disease, and use of antihypertensive medication were associated with increased HF risk. The area under the receiver operating characteristic curve of the model was 0.71, with a good calibration (χ² 7.9, P=0.54). A web‐based calculator was developed to allow easy calculations of the HF risk.

Conclusions

Simple measurements allow reliable estimation of the short‐term HF risk in populations and patients. The risk model may aid in risk stratification and future HF prevention strategies.

The GALA study: relationship between galectin-3 serum levels and short- and long-term outcomes of patients with acute heart failure

OBJECTIVE

We tested the hypothesis that early measurement of galectin-3 at the emergency department (ED) during an episode of acute heart failure (AHF) allows predicting short- and long-term outcomes.

METHODS

We performed an exploratory study including 115 patients consecutively diagnosed with AHF in a single ED. Clinical and analytical variables were recorded. The primary endpoint was 30-day all-cause mortality, and secondary endpoints were 30-day composite outcome (death, rehospitalization or ED reconsultation, whichever first) and 1-year mortality.

RESULTS

Seven patients (6.1%) died within 30 days and 43 (37.4%) within 1 year. The 30-day composite endpoint was observed in 21.1% of patients. Galectin-3 was correlated with NT-proBNP and the glomerular filtration rate but not with age and s-cTnI. Measured at time of ED arrival, galectin-3 showed good discriminatory capacity for 30-day mortality (AUC ROC: 0.732; 95% CI 0.512-0.953; p = 0.041) but not for 1-year mortality (0.521; 0.408-0.633; p = 0.722). Patients with galectin-3 concentrations >42 μg/L had an OR = 7.67(95%CI = 1.57-37.53; p = 0.012) for 30-day mortality. Conversely, NT-proBNP only showed predictive capacity for 1-year mortality (0.642; 0.537-0.748; p = 0.014). Patients with NT-proBNP concentrations >5400 ng/L had an OR = 4.34 (95%CI = 1.93-9.77; p < 0.001) for 1-year mortality. These increased short- (galectin-3) and long-term (NT-proBNP) risks remained significant after adjustment for age or renal function. s-cTnI failed in both short- and long term death prediction. No biomarker predicted the short-term composite endpoint.

CONCLUSION

These results suggest that galectin-3 could help to monitor the risk of short-term mortality in unselected patients with AHF attended in the ED.

Late onset cardiomyopathy as presenting sign of ATTR A45G amyloidosis caused by a novel TTR mutation (p.A65G)

OBJECTIVE

The clinical description of a novel TTR gene mutation characterized by a late onset amyloid cardiomyopathy.

METHODS AND RESULTS

A 78-year-old man of Dutch origin with recent surgery for bilateral carpal tunnel syndrome (CTS) was admitted to our hospital because of heart failure with preserved ejection fraction (55%). Cardiac ultrasound showed thickened biventricular walls, and cardiac magnetic resonance imaging also showed late gadolinium enhancement. Early signs of a polyneuropathy were found by neurophysiological testing. A few months later, his 72-year-old sister was admitted to an affiliated hospital because of heart failure caused by a restrictive cardiomyopathy. In both patients, a subcutaneous abdominal fat aspirate was stained with Congo red and DNA was analyzed by direct sequencing of exons 1 to 4 of the transthyretin (TTR) gene. Both fat aspirates revealed transthyretin-derived (ATTR) amyloid. ^99mTc-diphosphonate scintigraphy further confirmed cardiac ATTR amyloidosis in the male patient. DNA analysis of both patients showed a novel TTR mutation c.194C>G that encodes for the gene product TTR (p.A65G) ending up as the mature protein TTR A45G. The 56-year-old daughter of the male patient had the same TTR mutation. A full diagnostic workup did not reveal any signs of amyloidosis yet.

CONCLUSIONS

A novel amyloidogenic TTR mutation was found in a Dutch family. The clinical presentation of ATTR A45G amyloidosis in the affected family members was heart failure due to a late-onset cardiomyopathy. The systemic nature of this disease was reflected by bilateral CTS and by early signs of a polyneuropathy in the index patient.

Protocol update and preliminary results of EACVI/HFA Cardiac Oncology Toxicity (COT) Registry of the European Society of Cardiology

Aims

European Association of Cardiovascular Imaging/Heart Failure Association Cardiac Oncology Toxicity Registry was launched in October 2014 as a European Society of Cardiology multicentre registry of breast cancer patients referred to imaging laboratories for routine surveillance, suspected, or confirmed anticancer drug‐related cardiotoxicity (ADRC). After a pilot phase (1 year recruitment and 1 year follow‐up), some changes have been made to the protocol (version 1.0) and electronic case report form.

Methods and results

Main changes of the version 2.0 concerned exclusion criteria, registry duration, and clarification of the population characteristics. Breast cancer radiotherapy has been removed as an exclusion criterion, which involves now only history of a pre‐chemotherapy left ventricular dysfunction. The period for long‐term registry recruitment has been reduced (December 2017), but the target study population was extended to 3000 patients. The characteristics of the population are now better defined: patients seen in an imaging lab, which will include patients undergoing chemotherapy with associated targeted therapy or no targeted therapy, at increased risk of ADRC. In total, 1294 breast cancer patients have been enrolled, and 783 case report forms locked from October 2014 to November 2016. Of these, 481 (61.4%) were seen at first evaluation and 302 (38.6%) while on oncologic treatment with anticancer drugs. Fifty‐two patients (17.2%) were not in targeted therapies, 191 (63.3%) were ongoing targeted therapy, and 59 (19.5%) had completed it. Twenty‐three (2.9%) patients had a suspected diagnosis and 35 (4.5%) a confirmed diagnosis of ADRC. Arterial hypertension was the most prevalent cardiovascular risk factor (29.2%) followed by diabetes (6.1%). Previous history of heart failure accounted for 0.5%, whereas previous cardiac disease was identified in 6.3% of population.

Conclusion

The changes of the original protocol of the COT Registry and first update allow a first glance to the panorama of cardiovascular characteristics of breast cancer patients enrolled.

Integration of recent evidence into management of patients with atherosclerotic cardiovascular disease and type 2 diabetes

Cardiovascular outcome trials of antihyperglycaemic drugs and non-statin LDL-cholesterol-lowering drugs in patients with type 2 diabetes who have, or who are at high risk of, atherosclerotic cardiovascular disease have provided new evidence that has substantially affected the management of cardiovascular risk in these patients. On the basis of proven cardiovascular and renal benefit, the antihyperglycaemic drugs empagliflozin, liraglutide, and semaglutide-the latter being under review for approval by the US Food and Drug Administration and the European Medicines Agency-should be preferentially used as second-line treatments in these patient populations, typically in addition to metformin. Further treatment differentiation among the remainder of the antihyperglycaemic drugs should be made on the basis of evidence regarding cardiovascular safety, which is available for lixisenatide, alogliptin, saxagliptin, sitagliptin, and insulin glargine. The risk of heart failure, stroke, or retinopathy, or prevalent fasting versus postprandial hyperglycaemia, could also be considered in treatment decision making. Finally, emerging evidence of cardiovascular benefit for ezetimibe, alirocumab, and evolocumab positions these drugs as add-ons to maximally tolerated statin therapy or for those with statin intolerance.

Palliative care in heart failure: facts and numbers

Millions of people worldwide have heart failure. Despite enormous advances in care that have improved outcome, heart failure remains associated with a poor prognosis. Worldwide, there is poor short-term and long-term survival. The 1 year survival following a heart failure admission is in the range of 20-40% with between-country variation. For those living with heart failure, the symptom burden is high. Studies report that 55 to 95% of patients experience shortness of breath and 63 to 93% experience tiredness. These symptoms are associated with a high level of distress (43-89%). Fewer patients experience symptoms such as constipation (25-30%) or dry mouth (35-74%). However, when they do, such symptoms are associated with high levels of distress (constipation: 15-39%; dry mouth: 14-33%). Psychological symptoms also predominate with possibly as many as 50% experiencing depression. Palliative care services in heart failure are not widely available. Even in countries with well-developed services, only around 4% of patients are referred for specialist palliative care. Many patients and their families would benefit from receiving specialist palliative care support.

Elevation of plasma oncostatin M in heart failure

Aim: Oncostatin M (OSM) is an inflammatory cytokine of the gp130 family. OSM could participate in adverse cardiovascular remodeling through regulation of FGF23. Materials & methods: OSM levels were determined in 80 heart failure patients with reduced left ventricular ejection fraction (HFrEF). Results: OSM levels are significantly increased in HFrEF patients compared with healthy subjects. We have also demonstrated that, in HFrEF patients, plasma OSM levels are correlated to parathyroid hormone PTH(1–84) and 1,25(OH)2D, two other biomarkers related to bone and mineral metabolism and associated to adverse cardiovascular outcomes. Conclusion: OSM concentrations are elevated in HFrEF patients and could interplay with parathyroid hormone and vitamin D impacting cardiovascular function. Nevertheless, the prognostic value of OSM testing appears limited.

The future of telemedicine for the management of heart failure patients: a Consensus Document of the Italian Association of Hospital Cardiologists (A.N.M.C.O), the Italian Society of Cardiology (S.I.C.) and the Italian Society for Telemedicine and eHealth (Digital S.I.T.)

Telemedicine applied to heart failure patients is a tool for recording and providing remote transmission, storage and interpretation of cardiovascular parameters and/or useful diagnostic images to allow for intensive home monitoring of patients with advanced heart failure, or during the vulnerable post-acute phase, to improve patient's prognosis and quality of life. Recently, several meta-analyses have shown that telemedicine-supported care pathways are not only effective but also economically advantageous. Benefits seem to be substantial, with a 30-35% reduction in mortality and 15-20% decrease in hospitalizations. Patients implanted with cardiac devices can also benefit from an integrated remote clinical management since all modern devices can transmit technical and diagnostic data. However, telemedicine may provide benefits to heart failure patients only as part of a shared and integrated multi-disciplinary and multi-professional 'chronic care model'. Moreover, the future development of remote telemonitoring programs in Italy will require the primary use of products certified as medical devices, validated organizational solutions as well as legislative and administrative adoption of new care methods and the widespread growth of clinical care competence to remotely manage the complexity of chronicity. Through this consensus document, Italian Cardiology reaffirms its willingness to contribute promoting a new phase of qualitative assessment, standardization of processes and testing of telemedicine-based care models in heart failure. By recognizing the relevance of telemedicine for the care of non-hospitalized patients with heart failure, its strategic importance for the design of innovative models of care, and the many challenges and opportunities it raises, ANMCO and SIC through this document report a consensus on the main directions for its widespread and sustainable clinical implementation.

True Anemia―Red Blood Cell Volume Deficit―in Heart Failure

Background—

Anemia in heart failure (HF) is commonly diagnosed according to hemoglobin concentration [Hb], hence may be the result of hemodilution or true red blood cell volume (RBCV) deficit. Whether true (nonhemodilutional) anemia in HF can or cannot be generally inferred by [Hb] measurements and clinical correlates remains unclear. The purpose of this study was to systematically review the literature and investigate the status and correlates of RBCV in patients with HF.

Methods and Results—

MEDLINE, Scopus, and Web of Science were searched since their inceptions until April 2016 for articles directly reporting or allowing the calculation of intravascular volumes (RBCV, plasma volume) in patients with HF according to the International Council for Standardization in Hematology. Eighteen studies were included after systematic review, comprising a total of 368 patients with HF (limits for mean age=49–80 years, sex=0%–92% females, left ventricular ejection fraction=26%–61%). Mean RBCV was reduced (limits=67%–88% of normal) in all studies including HF patients with anemia (low [Hb]) (7 studies, n=127), whereas only 2 of 10 studies in nonanemic patients with HF presented lower than normal mean RBCV (90% and 96%). In metaregression analyses, RBCV was positively associated with [Hb] ( B =6.10, SE=1.44) and negatively associated with age ( B =−1.14, SE=0.23), % females ( B =−0.38, SE=0.04), left ventricular ejection fraction ( B =−0.81, SE=0.20), and body mass index ( B =−3.55, SE=0.46; P <0.001).

Conclusions—

Presence or absence of true anemia in patients with HF as determined by RBCV status mainly concurs with diagnosis based on [Hb] and presents negative relationships with age, female sex, left ventricular ejection fraction, and body mass index.

Resetting the neurohormonal balance in heart failure (HF): the relevance of the natriuretic peptide (NP) system to the clinical management of patients with HF

The natriuretic peptide (NP) system, which includes atrial natriuretic peptide, B-type natriuretic peptide, and C-type natriuretic peptide, has an important role in cardiovascular homeostasis, promoting a number of physiological effects including diuresis, vasodilation, and inhibition of the renin-angiotensin-aldosterone system. Heart failure (HF) is associated with defects in NP processing and synthesis, and there is a strong relationship between NP levels and disease state. NPs are useful biomarkers in HF, and their use in diagnosis and evaluation of prognosis is well established, particularly in patients with HF with reduced ejection fraction (HFrEF). There has also been interest in their use to guide disease management and therapeutic decision making. An understanding of NPs in HF has also resulted in interest in synthetic NPs for the treatment of HF and in treatments that target neprilysin, a protease that degrades NPs. A novel drug, the angiotensin receptor neprilysin inhibitor sacubitril/valsartan (LCZ696), which simultaneously inhibits neprilysin and blocks the angiotensin II type I receptor, was shown to have a favorable efficacy and safety profile in patients with HFrEF and has been approved for use in such patients in Europe and the USA. In light of the development of treatments that target neprilysin and of recent data in relation to synthetic NPs, it is timely to review the current understanding of the role of NPs in HF and their use in diagnosis, evaluating prognosis and guiding treatment, as well as their place in HF therapy.
