European Society of Cardiology Heart Failure Long-Term Registry (ESC-HF-LT): 1-year follow-up outcomes and differences across regions

Heart failure drug treatment

Heart failure is the most common cardiovascular reason for hospital admission for people older than 60 years of age. Few areas in medicine have progressed as remarkably as heart failure treatment over the past three decades. However, progress has been consistent only for chronic heart failure with reduced ejection fraction. In acutely decompensated heart failure and heart failure with preserved ejection fraction, none of the treatments tested to date have been definitively proven to improve survival. Delaying or preventing heart failure has become increasingly important in patients who are prone to heart failure. The prevention of worsening chronic heart failure and hospitalisations for acute decompensation is also of great importance. The objective of this Series paper is to provide a concise and practical summary of the available drug treatments for heart failure. We support the implementation of the international guidelines. We offer views on the basis of our personal experience in research areas that have insufficient evidence. The best possible evidence-based drug treatment (including inhibitors of the renin-angiotensin-aldosterone system and β blockers) is useful only when optimally implemented. However, implementation might be challenging. We believe that disease management programmes can be helpful in providing a multidisciplinary, holistic approach to the delivery of optimal medical care.

Patients with HFpEF and HFmrEF have different clinical characteristics in Turkey: A multicenter observational study

BACKGROUND

To determine and compare the demographic characteristics, clinical profile and management of patients with heart failure with mid-range ejection fraction (HFmrEF) and heart failure with preserved ejection fraction (HFpEF) in a Turkish cohort.

METHODS

The APOLLON trial (A comPrehensive, ObservationaL registry of heart faiLure with mid-range and preserved ejection fractiON) is an observational and multicenter study conducted in Turkey. Consecutive patients admitted to the cardiology clinics who were at least 18 years of age and had HFmrEF or HFpEF were included (NCT03026114).

RESULTS

The study population included 1065 (mean age of 67.1 ± 10.6 years, 54% women) patients from 12 sites in Turkey. Among participants, 246 (23.1%) had HFmrEF and 819 (76.9%) had HFpEF. Compared to patients with HFpEF, those with HFmrEF were more likely to be male (57.7 vs 42.2%; p < 0.001), had higher N-terminal pro-B-type natriuretic peptide levels (853 vs 528 pg/ml, p < 0.001), were more likely to have ECG abnormalities (72.4 vs 53.5%, p < 0.001) and hospitalization history for heart failure (28 vs 18.6%; p = 0.002). HFmrEF patients were more likely to use β-blockers (69.9 vs 55.2%, p < 0.001), aldosterone receptor antagonists (24 vs 14.7%, p = 0.001), statins (37 vs 23%, p < .001), and loop diuretics (39.8 vs 30.5%, p = 0.006) compared to patients with HFpEF.

CONCLUSIONS

The results of APOLLON study support that the basic characteristics and etiology of HFmrEF are significantly different from HFpEF. This registry also showed that the patients with HFmrEF and HFpEF were younger but undertreated in Turkey compared to patients in western countries.

Trends in survival after a diagnosis of heart failure in the United Kingdom 2000-2017: population based cohort study

OBJECTIVES

To report reliable estimates of short term and long term survival rates for people with a diagnosis of heart failure and to assess trends over time by year of diagnosis, hospital admission, and socioeconomic group.

DESIGN

Population based cohort study.

SETTING

Primary care, United Kingdom.

PARTICIPANTS

Primary care data for 55 959 patients aged 45 and overwith a new diagnosis of heart failure and 278 679 age and sex matched controls in the Clinical Practice Research Datalink from 1 January 2000 to 31 December 2017 and linked to inpatient Hospital Episode Statistics and Office for National Statistics mortality data.

MAIN OUTCOME MEASURES

Survival rates at one, five, and 10 years and cause of death for people with and without heart failure; and temporal trends in survival by year of diagnosis, hospital admission, and socioeconomic group.

RESULTS

Overall, one, five, and 10 year survival rates increased by 6.6% (from 74.2% in 2000 to 80.8% in 2016), 7.2% (from 41.0% in 2000 to 48.2% in 2012), and 6.4% (from 19.8% in 2000 to 26.2% in 2007), respectively. There were 30 906 deaths in the heart failure group over the study period. Heart failure was listed on the death certificate in 13 093 (42.4%) of these patients, and in 2237 (7.2%) it was the primary cause of death. Improvement in survival was greater for patients not requiring admission to hospital around the time of diagnosis (median difference 2.4 years; 5.3 v 2.9 years, P<0.001). There was a deprivation gap in median survival of 0.5 years between people who were least deprived and those who were most deprived (4.6 v 4.1 years, P<0.001) [corrected].

CONCLUSIONS

Survival after a diagnosis of heart failure has shown only modest improvement in the 21st century and lags behind other serious conditions, such as cancer. New strategies to achieve timely diagnosis and treatment initiation in primary care for all socioeconomic groups should be a priority for future research and policy.

Ultrafiltration in Acute Heart Failure

Congestion is the predominant cause of more than 1 million annual heart failure hospitalisations and recurrent fluid overload predicts poor outcomes. Unresolved congestion trumps serum creatinine increases in predicting adverse heart failure outcomes. No pharmacological approach for acute heart failure has reduced these deleterious consequences. Simplified ultrafiltration devices permit fluid removal in lower acuity hospital settings, but results regarding safety and efficacy have been variable. However, adjustment of ultrafiltration rates to patients’ vital signs and renal function has been associated with more effective decongestion and fewer heart failure events. Many aspects of ultrafiltration, including patient selection, fluid removal rates, venous access, prevention of therapy-related complications and costs, require further investigation.

Hospitalisation and life support in the year before and during heart transplantation: a French national study

Objective

The objective of this study was to define the characteristics of hospital care use during the year prior to heart transplantation.

Methods

A retrospective cohort of heart transplant recipients registered on the national hospital discharge database between 2010 and 2015 was analysed.

Results

In this cohort of 2379 heart transplant recipients (mean age: 48 years, 74% men), 91% had been admitted at least once, for at least 1 day, to a short-stay hospital during the year before transplantation (mean: 4.3 days), and 84% had at least one cardiovascular diagnosis (heart failure and cardiogenic shock: 60%). At least one intensive care stay was reported for 61% of patients, a rehabilitation stay was reported for 30%, mechanical circulatory support was reported for 12%, and ventilatory support was reported for 15%. The median interval between admission and transplantation was 5 days (interquartile QI-Q3, 0-16). The hospital mortality was higher for patients not hospitalised before transplantation (18% vs 15%). Their transplantation hospitalisation diagnosis, compared with patients hospitalised before transplantation, was more frequently cardiomyopathy (31% vs 27%) or heart failure (28% vs 18%), and less frequently myocardial infarction (1% vs 12%).

Conclusion

This study demonstrates a high hospitalisation rate before heart transplantation and identifies three groups of patients: 1-patients with a high hospitalisation rate and terminal heart failure requiring circulatory support who experienced at least one intensive care unit stay; 2-patients with a history of hospitalisation, mainly for heart disease, without circulatory support requirement; and 3-patients with no pretransplantation overnight stay. These findings provide useful information to evaluate the medical benefits and needs for transplantation, and identify areas for improvement in heart transplantation listing criteria.

Safety and Tolerability of the Chymase Inhibitor Fulacimstat in Patients With Left Ventricular Dysfunction After Myocardial Infarction-Results of the CHIARA MIA 1 Trial

The chymase inhibitor fulacimstat is developed as a first-in-class treatment option for the inhibition of adverse cardiac remodeling in patients with left ventricular dysfunction (LVD) after acute myocardial infarction (MI). The aim of the study was to examine the safety and tolerability of fulacimstat in patients with LVD after remote MI. A multicenter, multinational randomized, placebo-controlled study was performed in clinically stable patients (40-79 years of age, left ventricular ejection fraction ≤ 45% because of MI in medical history) who were on stable evidence-based standard-of-care therapies for LVD post-MI including an angiotensin converting enzyme inhibitor or angiotensin receptor blocker at doses of at least half the recommended target dose. Patients were treated for 2 weeks with either placebo (n = 12) or 4 different doses of fulacimstat (5 mg twice daily, n = 9; 10 mg twice daily, n = 9; 25 mg twice daily, n = 10; 50 mg once daily, n = 9). Fulacimstat was safe and well tolerated at all examined doses. There were no clinically relevant effects on vital signs or potassium levels compared with placebo treatment. Mean plasma concentrations of fulacimstat increased with the administered dose and reached exposures predicted to be therapeutically active. The safety profile and the absence of effects on blood pressure or heart rate in a chronic patient population having similar comorbidities and receiving similar comedication as patients after acute MI support future clinical trials with fulacimstat in patients after acute MI.

Patterns of dyspnoea onset in patients with acute heart failure: clinical and prognostic implications

Aims

Despite attempts to improve the management of patients with acute heart failure (HF), virtually all therapeutic agents investigated in large clinical trials failed to show any consistent reduction in mortality and morbidity. Complexity of the clinical syndrome of acute HF seems to be likely an underlying explanation. Traditionally, clinical trials studied mixed patient populations with acute HF, and only recently, better clinical characterization of patients has been proposed. Dyspnoea is the most common presenting symptom related to hospital admission for acute HF. Whether in patients with acute HF, the pattern of symptoms onset preceding hospital admission is associated with clinical characteristics, and the outcomes have not yet been established.

Methods and results

We investigated 137 patients (mean age: 65 ± 13 years; 80% men) hospitalized due to acute HF with dyspnoea as major reported symptom, who were divided according to the time of its onset into those with acute (n = 98) vs. subacute (n = 39) onset (i.e. within 7 days vs. >7 days preceding hospital admission, respectively). On admission, the former group presented higher blood pressure (138 ± 33 vs. 121 ± 32 mmHg), more often moderate–severe pulmonary congestion (33 vs. 8%), and lower bilirubin level [1.07 (0.72–1.60) vs. 1.27 (0.87–2.06); P < 0.05 in all comparisons]. There were no other differences in baseline clinical characteristics and laboratory indices. Higher percentage of patients with an acute dyspnoea onset reported marked/moderate dyspnoea relief after 6 (18% vs. 7%), 24 (59% vs. 24%), and 48 h (80% vs. 46% assessed as an improvement of at least 5 points in self‐reported 10‐point Likert scale; P < 0.05 in all time points). In patients with an acute onset of dyspnoea after 48 h, a decrease of N‐terminal pro BNP was more frequently observed (83% vs. 65%), and the levels of endothelin‐1 were more reduced [−1.1 (−2.9–0.03) vs 0.4 (−2.2–1.4); all P < 0.05]. Patients with acute onset experienced less in‐hospital HF worsening (13% vs. 40%, P = 0.001), and 1 year cardiovascular mortality was significantly lower (20% vs. 41%, P = 0.01). On the multivariable analysis, subacute pattern of dyspnoea was independent predictor of 12 month cardiovascular mortality in patients with acute HF after adjusting for other prognostic factors: systolic blood pressure, urea, and HF de novo [hazard ratio (95% confidence interval): 2.32 (1.13–4.75), P = 0.02].

Conclusions

In patients with acute HF, the pattern of symptoms onset is associated with baseline differences in clinical characteristics, biomarker profile, response to standard treatment, and the long‐term outcomes. This is relevant information for planning future clinical trials.

Innovative imaging methods in heart failure: a shifting paradigm in cardiac assessment. Position statement on behalf of the Heart Failure Association of the European Society of Cardiology

Myriad advances in all fields of cardiac imaging have stimulated and reflected new understanding of cardiac performance, myocardial damage and the mechanisms of heart failure. In this paper, the Heart Failure Association assesses the potential usefulness of innovative imaging modalities in enabling more precise diagnostic and prognostic evaluation, as well as in guiding treatment strategies. Many new methods have gradually penetrated clinical practice and are on their way to becoming a part of routine evaluation. This paper focuses on myocardial deformation and three-dimensional ultrasound imaging; stress tests for the evaluation of contractile and filling function; the progress of magnetic resonance techniques; molecular imaging and other sound innovations. The Heart Failure Association aims to highlight the ways in which paradigms have shifted in several areas of cardiac assessment. These include reassessing of the simplified concept of ejection fraction and implementation of the new parameters of cardiac performance applicable to all heart failure phenotypes; switching from two-dimensional to more accurate and reproducible three-dimensional ultrasound volumetric evaluation; greater tissue characterization via recently developed magnetic resonance modalities; moving from assessing cardiac function and congestion at rest to assessing it during stress; from invasive to novel non-invasive hybrid techniques depicting coronary anatomy and myocardial perfusion; as well as from morphometry to the imaging of pathophysiologic processes such as inflammation and apoptosis. This position paper examines the specific benefits of imaging innovations for practitioners dealing with heart failure aetiology, risk stratification and monitoring, and, in addition, for scientists involved in the development of future research.

Repetitive levosimendan treatment in the management of advanced heart failure

Inotropes may be an appropriate treatment for patients with advanced heart failure (AdHF) who remain highly symptomatic despite optimized standard therapies. Objectives for inotrope use in these situations include relief of symptoms and improvement of quality of life, and reduction in unplanned hospitalizations and the costs associated with such episodes. All of these goals must be attained without compromising survival. Encouraging findings with intermittent cycles of intravenous levosimendan have emerged from a range of exploratory studies and from three larger controlled trials (LevoRep, LION-HEART, and LAICA) which offered some evidence of clinical advantage. In these settings, however, obtaining statistically robust data may prove elusive due to the difficulties of endpoint assessment in a complex medical condition with varying presentation and trajectory. Adoption of a composite clinical endpoint evaluated in a hierarchical manner may offer a workable solution to this problem. Such an instrument can explore the proposition that repetitive administration of levosimendan early in the period after discharge from an acute episode of worsening heart failure may be associated with greater subsequent clinical stability vis-à-vis standard therapy. The use of this methodology to develop a ‘stability score’ for each patient means that all participants in such a trial contribute to the overall outcome analysis through one or more of the hierarchical endpoints; this has helpful practical implications for the number of patients needed and the length of follow-up required to generate endpoint data. The LeoDOR study (NCT03437226), outlined in this review, has been designed to explore this new approach to outcome assessment in AdHF.

Repetitive levosimendan infusions for patients with advanced chronic heart failure in the vulnerable post-discharge period

Hospitalization for acute heart failure (HF) is associated with a substantial morbidity burden and with associated healthcare costs and an increased mortality risk. However, few if any major medical innovations have been witnessed in this area in recent times. Levosimendan is a first‐in‐class calcium sensitizer and potassium channel opener indicated for the management of acute HF. Experience in several clinical studies has indicated that administration of intravenous levosimendan in intermittent cycles may reduce hospitalization and mortality rates in patients with advanced HF; however, none of those trials were designed or powered to give conclusive insights into that possibility. This paper describes the rationale and protocol of LeoDOR (levosimendan infusions for patients with advanced chronic heart failure), a randomized, double‐blind, placebo‐controlled, international, multicentre trial that will explore the efficacy and safety of intermittent levosimendan therapy, in addition to optimized standard therapy, in patients following hospitalization for acute HF. Salient features of LeoDOR include the use of two treatment regimens, in order to evaluate the effects of different schedules and doses of levosimendan during a 12 week treatment phase, and the use of a global rank primary endpoint, in which all patients are ranked across three hierarchical groups ranging from time to death or urgent heart transplantation or implantation of a ventricular assist device to time to rehospitalization and, lastly, time‐averaged proportional change in N‐terminal pro‐brain natriuretic peptide. Secondary endpoints include changes in HF symptoms and functional status at 14 weeks.

Long-term mortality is increased in patients with undetected prediabetes and type-2 diabetes hospitalized for worsening heart failure and reduced ejection fraction

Background

We assessed the prevalence of newly diagnosed prediabetes and type-2 diabetes mellitus (T2DM), and their impact on long-term mortality in patients hospitalized for worsening heart failure with reduced ejection fraction (HFrEF).

Methods

We included patients hospitalized with HFrEF and New York Heart Association (NYHA) functional class II–III. Baseline two-hour oral glucose tolerance test was used to classify patients as normoglycaemic or having newly diagnosed prediabetes or T2DM. Outcomes included post-discharge all-cause and cardiovascular mortality during the median follow-up of 2.1 years.

Results

At baseline, out of 150 patients (mean-age 57 ± 12 years; 88% male), prediabetes was diagnosed in 65 (43%) patients, and T2DM in 29 (19%) patients. These patients were older and more often with NYHA class III symptoms, but distribution of comorbidities was similar to normoglycaemic patients. Taking normoglycaemic patients as a reference, adjusted risk of all-cause mortality was significantly increased both in patients with prediabetes (hazard ratio, 2.6; 95% confidence interval (CI), 1.1–6.3; p = 0.040) and in patients with T2DM (hazard ratio, 5.3; 95% CI, 1.7–15.3; p = 0.023). Likewise, both prediabetes (hazard ratio, 2.9; 95% CI, 1.1–7.9; p = 0.041) and T2DM (hazard ratio, 9.7; 95% CI 2.9–36.7; p = 0.018) independently increased the risk of cardiovascular mortality compared with normoglycaemic individuals. There was no interaction between either prediabetes or T2DM and heart failure aetiology or gender on study outcomes (all interaction p-values > 0.05).

Conclusions

Newly diagnosed prediabetes and T2DM are highly prevalent in patients hospitalized for worsening HFrEF and NYHA functional class II–III. Importantly, they impose independently increased long-term risk of higher all-cause and cardiovascular mortality.

Sex, drugs, and heart failure: a sex-sensitive review of the evidence base behind current heart failure clinical guidelines

Heart failure (HF) is a complex disease, almost as common in women as in men. Nonetheless, HF clinical presentation, prognosis, and aetiology vary by sex. This review summarizes the current state of sex-sensitive issues related to HF drugs included in treatment guidelines and suggests future directions for improved care. Heart failure presentation differs between female and male patients: females more often show with hypertensive aetiology and the preserved ejection fraction phenotype, while men more often show ischaemic aetiology and the reduced ejection fraction phenotype. Yet the HF clinical guidelines in Europe, the United States, and Canada do not reflect the sexual dimorphism. Further, in randomized clinical trials of HF medication, women are largely underrepresented, typically consisting of ≥70% men. Given the knowledge that some adverse drug reactions, such as torsade de pointes and angiotensin-converting enzyme inhibitor-induced cough, occur more frequently in women, we emphasize the need to test medications thoroughly in both sexes and explore sexual dimorphisms. To better represent all of the targeted patient population and provide better care for all, two kinds of change must come about: recruitment methods to randomized clinical trial samples need to evolve and the participation needs to seem more attractive to women.

Association Between High-Dose Spironolactone and Decongestion in Patients with Acute Heart Failure: An Observational Retrospective Study

BACKGROUND

Acute congestive heart failure (ACHF) is a state of severe, secondary hyperaldosteronism. Relief of congestion has prognostic implications. Our aim was to assess associations between high-dose spironolactone and (1) decongestion and (2) safety in patients with ACHF.

METHODS

The charts of 20 patients who were hospitalized with ACHF and received high doses of spironolactone (75-300 mg daily, group A) on top of standard of care (SOC) treatment were retrospectively studied and compared with the ones of 20 matched patients who received SOC treatment alone (group B).

RESULTS

The two groups were similar as per their baseline characteristics. Mean daily spironolactone dose was 143 ± 56 in group A vs. 25 ± 25 mg in group B (P < 0.001). Patients of group A demonstrated significantly greater daily urine output (median [25th, 75th percentile] 2.9 [2.3, 3.9] vs. 2.2 [1.9, 2.5] L/day, P = 0.009), daily weight loss (1.1 [0.9, 1.7] vs. 0.4 [0.2, 1.2] kg/day, P = 0.005) and total body weight loss (10.5 [7.3, 13.8] vs. 3.8 [3.0, 6.0] kg, P < 0.001) compared with patients of group B. There were no differences in incidence of renal dysfunction, hypokalemia and hyperkalemia.

CONCLUSION

In patients with ACHF, administration of high doses of spironolactone on top of SOC treatment appears safe and is associated with greater decongestion than SOC alone.

Ultrafiltration for the Treatment of Acute Heart Failure

Ultrafiltration (UF) mechanically removes excess fluid volume through an extracorporeal circuit and has been applied to clinical situations in which volume removal is the mainstay of therapy. Because of this ability, UF serves as an enticing method to treat acute heart failure (AHF) in which most symptoms are driven by congestion due to excess volume. Additional physiologic properties of UF and the biochemical composition of the extracted fluid confer additional theoretic benefits in the treatment of AHF. Herein the concepts underlying UF, clinical evidence evaluating its efficacy, and ongoing challenges understanding the role of UF are reviewed.

Evidence-based pharmacotherapies used in the postdischarge phase are associated with improved one-year survival in senior patients hospitalized with heart failure

AIM

Hospitalized heart failure (HF) patients have a poor prognosis postdischarge. We determined whether renin-angiotensin system inhibitors (RASI) and β-blockers dispensed to patients within 60 days post-HF hospital discharge are associated with improved 1-year survival.

METHODS

A retrospective population-based study was conducted in 4897 seniors, aged 65-84 years, alive at 60 days postindex HF hospitalization in Western Australia over 2003-2008. Dispensing of RASI and β-blocker dispensing was identified from the Pharmaceutical Benefits Scheme claims database linked to hospital admission and death records.

RESULTS

At 1-year posthospital discharge, the all-cause mortality and all-cause death or HF rehospitalization rate was 13.5% (n = 663) and 24.4% (n = 1193), respectively. Postdischarge RASI and β-blocker were dispensed in 77.4% and 53.0% of patients, respectively. Their use was associated with a lower inverse probability treatment weighted (IPTW) HR for 1-year mortality of 0.70, 95% CI 0.61-0.81 and 0.79, 95% CI 0.68-0.92, respectively (both P < 0.0001), with a survival advantage most evident in the subgroup (70.1%) of patients with ischemic HF. In the overall cohort, these therapies were also associated with reduced IPTW HRs for all-cause death or HF rehospitalization (both P < 0.005) but not for HF rehospitalization exclusively. Use of a β-blocker was associated with a reduced IPTW HR for HF rehospitalization in the ischemic HF subgroup only.

CONCLUSIONS

In a cohort of senior patients hospitalized with HF, dispensing of a RASI or β-blocker within 60 days postdischarge is associated with a 1-year survival benefit. Early postdischarge support programs after recent HF hospitalization should include measures to optimize adherence to evidence-based medications.

Factors associated with underuse of mineralocorticoid receptor antagonists in heart failure with reduced ejection fraction: an analysis of 11 215 patients from the Swedish Heart Failure Registry

AIM

Mineralocorticoid receptor antagonists (MRAs) improve outcomes in heart failure with reduced ejection fraction (HFrEF), but are underutilized. Hyperkalaemia may be one reason, but the underlying reasons for underuse are unknown. The aim of this study was to investigate the independent predictors of MRA underuse in a large and unselected HFrEF cohort.

METHODS AND RESULTS

We included patients with HFrEF (ejection fraction <40%), New York Heart Association (NYHA) class II-IV and heart failure (HF) duration ≥6 months from the Swedish HF Registry. Logistic regression analysis identified independent associations between 39 demographic, clinical, co-treatment, and socioeconomic predictors and MRA non-use. Of 11 215 patients, 27% were women; mean age was 75 ± 11 years; only 4443 (40%) patients received MRA. Selected characteristics independently associated with MRA non-use were in descending order of magnitude: lower creatinine clearance (<60 mL/min), no need for diuretics, no cardiac resynchronization therapy/implantable cardioverter-defibrillator, higher blood pressure, no digoxin use, higher ejection fraction, outpatient setting, older age, lower income, ischaemic heart disease, male sex, follow-up in primary vs. specialty care, lower NYHA class, and absence of hypertension diagnosis. Plasma potassium and N-terminal pro B-type natriuretic peptide levels were not associated with MRA non-use.

CONCLUSION

Mineralocorticoid receptor antagonists remain underused in HFrEF. Their use does not decrease with elevated potassium but does with impaired renal function, even in the creatinine clearance 30-59.9 mL/min range where MRAs are not contraindicated. MRA underuse may be further related to non-specialist care, milder HF and no use of other HF therapy.

The midrange left ventricular ejection fraction (LVEF) is associated with higher all-cause mortality during the 1-year follow-up compared to preserved LVEF among real-world patients with acute heart failure: a single-center propensity score-matched analysis

The objectives of the study were to characterize and compare different acute heart failure (AHF) subgroups according to left-ventricular ejection fraction (LVEF) in terms of all-cause mortality and HF-related readmissions during the 1-year follow-up (FU). Three hundred and fifty-six AHF patients admitted to Cardiology ward and/or CCU were retrospectively included in the study and analyzed during the 1-year FU. Patients were stratified according to LVEF as those with preserved (HFpEF), midrange (HFmrEF) and reduced LVEF (HFrEF). During the FU period, 148 (43.3%) patients died, and 116 HF-related readmission events were recorded. HFmrEF group had significantly higher standardized all-cause mortality rate, unadjusted for age, compared to HFpEF group and significantly lower than HFrEF group (41 vs. 18 and 41 vs. 62.5 events per 100 patient-years; χ² = 41.08, p < 0.001 and χ² = 16.62, p < 0.001, respectively). A propensity score-matched analysis in which all HF groups were matched for age and other covariates confirmed that HFmrEF group had significantly higher all-cause mortality rate than HFpEF group (χ² = 15.66, p < 0.001) while no significant differences in readmission rates were observed across all groups (p = NS). The hazard risk for a composite endpoint of death and readmission was highest in HFrEF group (HR 6.53, 95% CI 3.53-12.08, p < 0.001), followed by HFmrEF group (HR 3.30, 95% CI 1.86-5.87, p < 0.001) when compared to HFpEF group set as a reference. Among AHF patients, the HFmrEF phenotype was associated with significantly higher all-cause mortality compared to HFpEF, during the 1-year FU. This finding might implicate more stringent clinical approach towards this patient group.

In-hospital heart rate reduction and its relation to outcomes of heart failure patients with sinus rhythm: Results from the Polish part of the European Society of Cardiology Heart Failure Pilot and Long-Term Registries

BACKGROUND

Currently, there is no information on whether in-hospital heart rate (HR) reduction has an influence on risk of death or rehospitalization. The study evaluates the relation between inhospital HR reduction in heart failure (HF) patients on mortality and rehospitalization within 1-year observation.

METHODS

The analysis included patients hospitalized in Poland with sinus rhythm from the European Society of Cardiology Heart Failure Pilot (ESC-HF-Pilot) and ESC Heart Failure Long-Term Registries (ESC-HF-LT), who were divided into two groups: reduced HR and not-reduced HR. HR reduction was defined as a reduced value of HR at discharge compared to admission HR. The primary endpoint was 1-year all-cause death, the secondary endpoint was 1-year all-cause death or rehospitalization for worsening HF.

RESULTS

The final analysis included 747 patients; 491 reduced HR (65.7%) and 256 not-reduced HR (34.3%). The primary endpoint occurred in 58/476 (12.2%) from reduced HR group and in 26/246 (10.5%) from not-reduced HR group (p = 0.54). In the reduced HR group, independent predictors of primary endpoint were age, New York Heart Association class at admission, serum sodium level at admission and systolic blood pressure at discharge. In the not-reduced HR group the independent predictor of primary endpoint was diastolic blood pressure at discharge. The secondary endpoint was observed in 180 patients, 124/398 (31.2%) from reduced HR and 56/207 (27.1%) from the not-reduced HR group (p = 0.30). In the not-reduced HR group only angiotensin converting-enzyme inhibitor usage at discharge was independently associated with lower risk of the secondary endpoint.

CONCLUSIONS

In-hospital HR reduction did not influence on the outcomes of HF patients in sinus rhythm.

HF progression among outpatients with HF in a community setting

BACKGROUND

Incidence and prognostic impact of heart failure (HF) progression has been not well addressed.

METHODS

From 2009 until 2015, consecutive ambulatory HF patients were recruited. HF progression was defined by the presence of at least two of the following criteria: step up of ≥1 New York Heart Association (NYHA) class; decrease LVEF ≥ 10 points; association of diuretics or increase ≥ 50% of furosemide dosage, or HF hospitalization.

RESULTS

2528 met study criteria (mean age 76; 42% women). Of these, 48% had ischemic heart disease, 18% patients with LVEF ≤ 35%. During a median follow-up of 2.4 years, overall mortality was 31% (95% CI: 29%-33%), whereas rate of HF progression or death was 57% (95% CI: 55%-59%). The 4-year incidence of HF progression was 39% (95% CI: 37%-41%) whereas the competing mortality rate was 18% (95% CI: 16%-19%). Rates of HF progression and death were higher in HF patients with LVEF ≤ 35% vs >35% (HF progression: 42% vs 38%, p = 0.012; death as a competing risk: 22% vs 17%, p = 0.002). HF progression identified HF patients with a worse survival (HR = 3.16, 95% CI: 2.75-3.72). In cause-specific Cox models, age, previous HF hospitalization, chronic obstructive pulmonary disease, chronic kidney disease, anemia, sex, LVEF ≤ 35% emerged as prognostic factors of HF progression.

CONCLUSIONS

Among outpatients with HF, at 4 years 39% presented a HF progression, while 18% died before any sign of HF progression. This trend was higher in patients with LVEF ≤ 35%. These findings may have implications for healthcare planning and resource allocation.

Application of competing risks analysis improved prognostic assessment of patients with decompensated chronic heart failure and reduced left ventricular ejection fraction

OBJECTIVE

The Kaplan-Meier method may overestimate absolute mortality risk (AMR) in the presence of competing risks. Urgent heart transplantation (UHT) and ventricular assist device implantation (VADi) are important competing events in heart failure. We sought to quantify the extent of bias of the Kaplan-Meier method in estimating AMR in the presence of competing events and to analyze the effect of covariates on the hazard for death and competing events in the clinical model of decompensated chronic heart failure with reduced ejection fraction (DCHFrEF).

STUDY DESIGN AND SETTING

We studied 683 patients. We used the cumulative incidence function (CIF) to estimate the AMR at 1 year. CIF estimate was compared with the Kaplan-Meier estimate. The Fine-Gray subdistribution hazard analysis was used to assess the effect of covariates on the hazard for death and UHT/VADi.

RESULTS

The Kaplan-Meier estimate of the AMR was 0.272, whereas the CIF estimate was 0.246. The difference was more pronounced in the patient subgroup with advanced DCHF (0.424 vs. 0.338). The Fine-Gray subdistribution hazard analysis revealed that established risk markers have qualitatively different effects on the incidence of death or UHT/VADi.

CONCLUSION

Competing risks analysis allows more accurately estimating AMR and better understanding the association between covariates and major outcomes in DCHFrEF.

Prognostic evaluation of the elastic properties of the ascending aorta in dilated cardiomyopathy

BACKGROUND

Nowadays there is an increased interest in the role of aortic stiffness in the pathophysiology of heart failure (HF), as it is a major determinant of left ventricular (LV) performance. We aimed at assessing the predictive value of the aortic stiffness parameters, measured by echocardiography, in patients affected by nonischaemic dilated cardiomyopathy (DCM) regarding three end-points: death, HF rehospitalization, combined death or HF rehospitalization in a long-term follow-up.

MATERIALS AND METHODS

A total of 202 patients affected by nonischaemic DCM underwent an outpatient examination by echocardiography and blood pressure check at the brachial artery, in order to calculate aortic elastic properties (ie, compliance, distensibility, stiffness index, Peterson's elastic modulus, M-mode strain). ROC curves, Kaplan-Meier curves and multivariable Cox regressions (correcting for age, LV ejection fraction (LVEF), atrial fibrillation, cardiac resynchronization therapy (CRT)) were run to assess the predictive ability of aortic elastic properties against the 3 end-points.

RESULTS

Mean follow-up was 9.83 ± 2.80 years. 24.8% of patients died, while 34.7% were rehospitalized for HF cause and 44.6% experienced the combined end-point. LVEF did not correlate with aortic elastic properties. ROC curves and Kaplan-Meier curves were elaborated. Aortic stiffness did not predict death in our cohort. Otherwise, all aortic elastic properties predicted HF rehospitalization and combined death or HF rehospitalization, after correcting for age, LVEF, atrial fibrillation, CRT.

CONCLUSIONS

Elastic properties of the ascending aorta measured by echocardiography in patients with nonischaemic DCM predict long-term HF rehospitalization and combined death or HF rehospitalization, also after correcting for the confounding factors.

In-Hospital and Three-Year Outcomes of Heart Failure Patients in South India: The Trivandrum Heart Failure Registry

BACKGROUND

Long-term data on outcomes of participants hospitalized with heart failure (HF) from low- and middle-income countries are limited.

METHODS AND RESULTS

In the Trivandrum Heart Failure Registry (THFR) in 2013, 1205 participants from 18 hospitals in Trivandrum, India, were enrolled. Data were collected on demographics, clinical presentation, treatment, and outcomes. We performed survival analyses, compared groups and evaluated the association between heart failure (HF) type and mortality, adjusting for covariates that predicted mortality in a global HF risk score. The mean (standard deviation) age of participants was 61.2 (13.7) years. Ischemic heart disease was the most common cause (72%). The in-hospital mortality rate was higher for participants with HF with reduced ejection fraction (HFrEF; 9.7%) compared with those with HF with preserved ejection fraction (HFpEF; 4.8%; P = .003). After 3 years, 540 (44.8%) participants had died. The all-cause mortality rate was lower for participants with HFpEF (40.8%) compared with HFrEF (46.2%; P = .049). In multivariable models, older age (hazard ratio [HR] 1.24 per decade, 95% confidence interval [CI] 1.15-1.33), New York Heart Association functional class IV symptoms (HR 2.80, 95% CI 1.43-5.48), and higher serum creatinine (HR 1.12 per mg/dL, 95% CI 1.04-1.22) were associated with all-cause mortality.

CONCLUSIONS

Participants with HF in the THFR have high 3-year all-cause mortality. Targeted hospital-based quality improvement initiatives are needed to improve survival during and after hospitalization for HF.

Comprehensive in-hospital monitoring in acute heart failure: applications for clinical practice and future directions for research. A statement from the Acute Heart Failure Committee of the Heart Failure Association (HFA) of the European Society of Cardiology (ESC)

This paper provides a practical clinical application of guideline recommendations relating to the inpatient monitoring of patients with acute heart failure, through the evaluation of various clinical, biomarker, imaging, invasive and non-invasive approaches. Comprehensive inpatient monitoring is crucial to the optimal management of acute heart failure patients. The European Society of Cardiology heart failure guidelines provide recommendations for the inpatient monitoring of acute heart failure, but the level of evidence underpinning most recommendations is limited. Many tools are available for the in-hospital monitoring of patients with acute heart failure, and each plays a role at various points throughout the patient's treatment course, including the emergency department, intensive care or coronary care unit, and the general ward. Clinical judgment is the preeminent factor guiding application of inpatient monitoring tools, as the various techniques have different patient population targets. When applied appropriately, these techniques enable decision making. However, there is limited evidence demonstrating that implementation of these tools improves patient outcome. Research priorities are identified to address these gaps in evidence. Future research initiatives should aim to identify the optimal in-hospital monitoring strategies that decrease morbidity and prolong survival in patients with acute heart failure.

Rationale and design of TRANSITION: a randomized trial of pre-discharge vs. post-discharge initiation of sacubitril/valsartan

AIMS

The prognosis after hospitalization for acute decompensated heart failure (ADHF) remains poor, especially <30 days post-discharge. Evidence-based medications with prognostic impact administered at discharge improve survival and hospital readmission, but robust studies comparing pre-discharge with post-discharge initiation are rare. The PARADIGM-HF trial established sacubitril/valsartan as a new evidence-based therapy in patients with heart failure (HF) and reduced left ventricular ejection fraction (<40%) (rEF). In common with other landmark studies, it enrolled patients who were ambulatory at the time of inclusion. In addition, there is also still limited knowledge of initiation and up-titration of sacubitril/valsartan in ACEi/ARB- naïve patients and in de novo HF with rEF patients.

METHODS AND RESULTS

TRANSITION is a multicentre, open-label study in which ~1000 adults hospitalized for ADHF with rEF are randomized to start sacubitril/valsartan in a pre-discharge arm (initiated ≥24 h after haemodynamic stabilization) or a post-discharge arm (initiated within Days 1-14 after discharge). The protocol allows investigators to select the appropriate starting dose and dose adjustments according to clinical circumstances. Over a 10 week treatment period, the primary and secondary objectives assess the feasibility and safety of starting sacubitril/valsartan in-hospital, early after haemodynamic stabilization. Exploratory objectives also include assessment of HF signs and symptoms, readmissions, N-terminal pro-B-type natriuretic peptide and high-sensitivity troponin T levels, and health resource utilization parameters.

CONCLUSIONS

TRANSITION will provide new evidence about initiating sacubitril/valsartan following hospitalization for ADHF, occurring either as de novo ADHF or as deterioration of chronic HF, and in patients with or without prior ACEI/ARB therapy. The results of TRANSITION will thus be highly relevant to the management of patients hospitalized for ADHF with rEF.

Real-world heart failure management in 10,910 patients with chronic heart failure in the Netherlands : Design and rationale of the Chronic Heart failure ESC guideline-based Cardiology practice Quality project (CHECK-HF) registry

Aims

Data from patient registries give insight into the management of patients with heart failure (HF), but actual data from unselected real-world HF patients are scarce. Therefore, we performed a cross sectional study of current HF care in the period 2013–2016 among more than 10,000 unselected HF patients at HF outpatient clinics in the Netherlands.

Methods

In 34 participating centres, all 10,910 patients with chronic HF treated at cardiology centres were included in the CHECK-HF registry. Of these, most (96%) were managed at a specific HF outpatient clinic. Heart failure was typically diagnosed according to the ESC guidelines 2012, based on signs, symptoms and structural and/or functional cardiac abnormalities. Information on diagnostics, treatment and co-morbidities were recorded, with specific focus on drug therapy and devices. In our cohort, the mean age was 73 years (SD 12) and 60% were male. Frequent co-morbidities reported in the patient records were diabetes mellitus 30%, hypertension 43%, COPD 19%, and renal insufficiency 58%. In 47% of the patients, ischaemia was the origin of HF. In our registry, the prevalence of HF with preserved ejection fraction was 21%.

Conclusion

The CHECK-HF registry will provide insight into the current, real world management of patient with chronic HF, including HF with reduced ejection fraction, preserved ejection fraction and mid-range ejection fraction, that will help define ways to improve quality of care. Drug and device therapy and guideline adherence as well as interactions with age, gender and co-morbidities will receive specific attention.

Age affects the prognostic impact of diabetes in chronic heart failure

AIMS

Increasing age is an established prognostic determinant in chronic heart failure (HF). Diabetes often complicates HF in its course and appears to worsen HF prognosis. A differential impact of diabetes depending on patients' age was not yet studied. We evaluated the impact of diabetes in the mortality of HF patients according to their age.

METHODS

We studied a cohort of chronic ambulatory HF patients prospectively recruited. Patients were on optimized evidence-based therapy, and they were excluded if on renal replacement therapy or if they had any therapy modification or hospitalizations in the previous 2 months. Patients were followed for up to 5 years; all-cause mortality was analyzed. Mortality predictors were assessed using a Cox regression. Analysis was stratified according to patient's age: cutoff 75 years. Multivariate models were built. Interaction between diabetes and age was formally tested.

RESULTS

We studied 283 chronic HF patients; mean age was 69 years and 70.3% were male; 58.0% had severe systolic dysfunction; 105 (37.1%) were diabetic. In patients with less than 75 years, the coexistence of diabetes predicted a multivariate adjusted 1.98 (95% CI 1.13-3.46) 5-year death risk while in older patients (≥ 75 years) no significant association was reported. Age interacted with the prognostic impact of diabetes, p for interaction = 0.04.

CONCLUSIONS

The prognostic impact of diabetes in chronic HF depends on patient's age. In patients < 75 years, the coexistence of diabetes predicts an almost double risk of 5-year mortality; no such association exists in patients with 75 years or above. Diabetes predicts mortality only in younger HF patients.

Prevalence and incidence of hyperkalaemia in the Spanish population with heart failure with reduced ejection fraction: a systematic review and populational relevance

BACKGROUND AND OBJECTIVES

Hyperkalaemia (K⁺ levels≥5.5mmol/L) is a severe ion imbalance that occurs in patients who have heart failure (HF) with reduced ejection fraction (HFrEF) and increases the risk of ventricular fibrillation. Given that there are no estimates on the number of patients with this complication, the aim of this study was to estimate the prevalence and incidence of hyperkalaemia in patients with HFrEF in Spain.

MATERIAL AND METHODS

Based on a systematic literature search and through a meta-analysis, we calculated an HFrEF prevalence of ≤40% in the European and U.S.

POPULATION

Based on another systematic literature search, we calculated the prevalence of hyperkalaemia in patients with HF and its annual incidence rate. Considering the previous values and the Spanish population pyramid in 2016, we estimated the number of individuals with HFrEF who currently have hyperkalaemia and those who develop it each year in Spain.

RESULTS

Approximately 17,100 (10,000 men and 7100 women) of the 508,000 patients with HFrEF in Spain have hyperkalaemia. Furthermore, approximately 14,900 patients with HFrEF (9500 men and 5400 women) develop hyperkalaemia each year.

CONCLUSIONS

Approximately 1 of every 30 patients with HFrEF has plasma potassium values >5.5 mmol/L.

Cognitive performance in late adolescence and long-term risk of early heart failure in Swedish men

Aims

Heart failure (HF) incidence appears to increase among younger individuals, raising questions of how risk factors affect the younger population. We investigated the association of cognitive performance in late adolescence with long‐term risk of early HF.

Methods and results

We followed a cohort of Swedish men enrolled in mandatory military conscription in 1968–2005 (n = 1 225 300; mean age 18.3 years) until 2014 for HF hospitalization, using data from the Swedish National Inpatient Registry. Cognitive performance (IQ) was measured through a combination of tests, separately evaluating logical, verbal, visuospatial, and technical abilities. The results were standardized, weighted, and presented as stanines of IQ. The association between IQ and risk of HF was estimated using Cox proportional hazards models. In follow‐up, there were 7633 cases of a first HF hospitalization (mean age at diagnosis 50.1 years). We found an inverse relationship between global IQ and risk of HF hospitalization. Using the highest IQ stanine as reference, the adjusted hazard ratio for the lowest IQ with risk of HF was 3.11 (95% confidence interval 2.60–3.71), corresponding to a hazard ratio of 1.32 (95% CI 1.28–1.35) per standard deviation decrease of IQ. This association proved persistent across predefined categories of HF with respect to pre‐existing or concomitant co‐morbidities; it was less apparent among obese conscripts (P for interaction =0.0004).

Conclusion

In this study of young men, IQ was strongly associated with increased risk of early HF. The medical profession needs to be aware of this finding so as to not defer diagnosis.
