Congestion in Patients with Advanced Heart Failure: Assessment and Treatment

2024 update in heart failure

In the last years, major progress has occurred in heart failure (HF) management. The 2023 ESC focused update of the 2021 HF guidelines introduced new key recommendations based on the results of the last years of science. First, two drugs, sodium-glucose co-transporter-2 (SGLT2) inhibitors and finerenone, a novel nonsteroidal, selective mineralocorticoid receptor antagonist (MRA), are recommended for the prevention of HF in patients with diabetic chronic kidney disease (CKD). Second, SGLT2 inhibitors are now recommended for the treatment of HF across the entire left ventricular ejection fraction spectrum. The benefits of quadruple therapy in patients with HF with reduced ejection fraction (HFrEF) are well established. Its rapid and early up-titration along with a close follow-up with frequent clinical and laboratory re-assessment after an episode of acute HF (the so-called 'high-intensity care' strategy) was associated with better outcomes in the STRONG-HF trial. Patients experiencing an episode of worsening HF might require a fifth drug, vericiguat. In the STEP-HFpEF-DM and STEP-HFpEF trials, semaglutide 2.4 mg once weekly administered for 1 year decreased body weight and significantly improved quality of life and the 6 min walk distance in obese patients with HF with preserved ejection fraction (HFpEF) with or without a history of diabetes. Further data on safety and efficacy, including also hard endpoints, are needed to support the addition of acetazolamide or hydrochlorothiazide to a standard diuretic regimen in patients hospitalized due to acute HF. In the meantime, PUSH-AHF supported the use of natriuresis-guided diuretic therapy. Further options and most recent evidence for the treatment of HF, including specific drugs for cardiomyopathies (i.e., mavacamten in hypertrophic cardiomyopathy and tafamidis in transthyretin cardiac amyloidosis), device therapies, cardiac contractility modulation and percutaneous treatment of valvulopathies, with the recent finding from the TRILUMINATE Pivotal trial, are also reviewed in this article.

Clinical and prognostic implications of heart failure hospitalization in patients with advanced heart failure

BACKGROUND

Hospitalization is associated with poor outcomes in patients with heart failure, but its prognostic role in advanced heart failure is still unsettled. We evaluated the prognostic role of heart failure hospitalization in patients with advanced heart failure.

METHODS

The multicenter HELP-HF registry enrolled consecutive patients with heart failure and at least one high-risk 'I NEED HELP' marker. Characteristics and outcomes were compared between patients who were hospitalized for decompensated heart failure (inpatients) or not (outpatients) at the time of enrolment. The primary endpoint was the composite of all-cause mortality or first heart failure hospitalization.

RESULTS

Among the 1149 patients included [mean age 75.1 ± 11.5 years, 67.3% men, median left ventricular ejection fraction (LVEF) 35% (IQR 25-50%)], 777 (67.6%) were inpatients at the time of enrolment. As compared with outpatients, inpatients had lower LVEF, higher natriuretic peptides and a worse clinical profile. The 1-year rate of the primary endpoint was 50.9% in inpatients versus 36.8% in outpatients [crude hazard ratio 1.70, 95% confidence interval (CI) 1.39-2.07, P < 0.001]. At multivariable analysis, inpatient status was independently associated with a higher risk of the primary endpoint (adjusted hazard ratio 1.54, 95% CI 1.23-1.93, P < 0.001). Among inpatients, the independent predictors of the primary endpoint were older age, lower SBP, heart failure association criteria for advanced heart failure and glomerular filtration rate 30 ml/min/1.73 m2 or less.

CONCLUSION

Hospitalization for heart failure in patients with at least one high-risk 'I NEED HELP' marker is associated with an extremely poor prognosis supporting the need for specific interventions, such as mechanical circulatory support or heart transplantation.

Detailed Assessment of the "I Need Help" Criteria in Patients With Heart Failure: Insights From the HELP-HF Registry

BACKGROUND

The "I Need Help" markers have been proposed to identify patients with advanced heart failure (HF). We evaluated the prognostic impact of these markers on clinical outcomes in a real-world, contemporary, multicenter HF population.

METHODS

We included consecutive patients with HF and at least 1 high-risk "I Need Help" marker from 4 centers. The impact of the cumulative number of "I Need Help" criteria and that of each individual "I Need Help" criterion was evaluated. The primary end point was the composite of all-cause mortality or first HF hospitalization.

RESULTS

Among 1149 patients enrolled, the majority had 2 (30.9%) or 3 (22.6%) "I Need Help" criteria. A higher cumulative number of "I Need Help" criteria was independently associated with a higher risk of the primary end point (adjusted hazard ratio for each criterion increase, 1.19 [95% CI, 1.11-1.27]; P<0.001), and patients with >5 criteria had the worst prognosis. Need of inotropes, persistently high New York Heart Association classes III and IV or natriuretic peptides, end-organ dysfunction, >1 HF hospitalization in the last year, persisting fluid overload or escalating diuretics, and low blood pressure were the individual criteria independently associated with a higher risk of the primary end point.

CONCLUSIONS

In our HF population, a higher number of "I Need Help" criteria was associated with a worse prognosis. The individual criteria with an independent impact on mortality or HF hospitalization were need of inotropes, New York Heart Association class or natriuretic peptides, end-organ dysfunction, multiple HF hospitalizations, persisting edema or escalating diuretics, and low blood pressure.

Prognostic role of tricuspid annular plane systolic excursion/pulmonary artery systolic pressure ratio in patients hospitalized for acute heart failure

BACKGROUND

The role of TAPSE/PASP, a measurement of right ventricular to pulmonary artery coupling, in patients hospitalized for acute heart failure (AHF) is poorly described.

OBJECTIVES

To evaluate the prognostic impact of TAPSE/PASP in AHF.

METHODS

This retrospective single-center study included patients hospitalized for AHF between January 2004 and May 2017. TAPSE/PASP was evaluated as a continuous variable and as tertiles according to its value on admission. The main outcome was the composite of 1-year all-cause death or heart failure hospitalization.

RESULTS

A total of 340 patients were included [mean age 68.8 ± 11.8 years; 76.2% men, mean left ventricular ejection fraction (LVEF) 30.4 ± 13.3%]. Patients with lower TAPSE/PASP had more comorbidities and a more advanced clinical profile, and received higher doses of intravenous furosemide in the first 24 h. There was a significant, linear, inverse relationship between TAPSE/PASP values and the incidence of the main outcome (P = 0.003). In two multivariable analyses including clinical (model 1), biochemical and imaging parameters (model 2) TAPSE/PASP ratio was independently associated with the primary end point [model 1: hazard ratio 0.813, 95% confidence interval (CI) 0.708-0.932, P = 0.003; model 2: hazard ratio 0.879, 95% CI 0.775-0.996, P = 0.043]. Patients with TAPSE/PASP greater than 0.47 mm/mmHg had a significantly lower risk of the primary end point (model 1: hazard ratio 0.473, 95% CI 0.277-0.808, P = 0.006; model 2: hazard ratio 0.582, 95% CI 0.355-0.955, P = 0.032; both compared with TAPSE/PASP <0.34 mm/mmHg). Similar findings were observed for 1-year all-cause mortality.

CONCLUSION

TAPSE/PASP on admission demonstrated a prognostic value among patients with AHF.

Updates in heart failure: sodium glucose co-transporter 2 inhibitors and beyond – major changes are coming

Prevalence of heart failure is increasing worldwide mainly due to the ageing of the population and the improvement in diagnosis and treatment. In recent years, huge progress has been made in the management of heart failure patients. A new definition of chronic heart failure based on left ventricular ejection fraction and its possible trajectories has been reported. New drug classes have been introduced for the treatment of chronic heart failure. In particular, the prognostic benefit of sodium glucose co-transporter 2 inhibitors was demonstrated across all the heart failure phenotypes. Therapies for patients with advanced heart failure (long-term mechanical circulatory supports and heart transplantation) are now indicated also in the case of mild-to-moderate symptoms but with high risk of progression. In patients with acute heart failure, monitoring of urinary sodium and the use of acetazolamide may lead to better decongestion. Importantly, pre- and postdischarge assessment should lead to optimal treatment. Devices and telemonitoring can also be of help. Cardiovascular and noncardiovascular comorbidities are major determinants of the clinical course and need proper management. This review will summarize these important advances.

Heart failure: an update from the last years and a look at the near future

In the last years, major progress occurred in heart failure (HF) management. Quadruple therapy is now mandatory for all the patients with HF with reduced ejection fraction. Whilst verciguat is becoming available across several countries, omecamtiv mecarbil is waiting to be released for clinical use. Concurrent use of potassium-lowering agents may counteract hyperkalaemia and facilitate renin-angiotensin-aldosterone system inhibitor implementations. The results of the EMPagliflozin outcomE tRial in Patients With chrOnic heaRt Failure With Preserved Ejection Fraction (EMPEROR-Preserved) trial were confirmed by the Dapagliflozin in Heart Failure with Mildly Reduced or Preserved Ejection Fraction (DELIVER) trial, and we now have, for the first time, evidence for treatment of also patients with HF with preserved ejection fraction. In a pre-specified meta-analysis of major randomized controlled trials, sodium-glucose co-transporter-2 inhibitors reduced all-cause mortality, cardiovascular (CV) mortality, and HF hospitalization in the patients with HF regardless of left ventricular ejection fraction. Other steps forward have occurred in the treatment of decompensated HF. Acetazolamide in Acute Decompensated Heart Failure with Volume Overload (ADVOR) trial showed that the addition of intravenous acetazolamide to loop diuretics leads to greater decongestion vs. placebo. The addition of hydrochlorothiazide to loop diuretics was evaluated in the CLOROTIC trial. Torasemide did not change outcomes, compared with furosemide, in TRANSFORM-HF. Ferric derisomaltose had an effect on the primary outcome of CV mortality or HF rehospitalizations in IRONMAN (rate ratio 0.82; 95% confidence interval 0.66-1.02; P = 0.070). Further options for the treatment of HF, including device therapies, cardiac contractility modulation, and percutaneous treatment of valvulopathies, are summarized in this article.

Prognostic impact of the updated 2018 HFA-ESC definition of advanced heart failure: results from the HELP-HF registry

AIMS

The Heart Failure Association of the European Society of Cardiology (HFA-ESC) proposed a definition of advanced heart failure (HF) that has not been validated, yet. We assessed its prognostic impact in a consecutive series of patients with high-risk HF.

METHODS AND RESULTS

The HELP-HF registry enrolled consecutive patients with HF and at least one high-risk 'I NEED HELP' marker, evaluated at four Italian centres between 1^st January 2020 and 30^th November 2021. Patients meeting the HFA-ESC advanced HF definition were compared to patients not meeting this definition. The primary endpoint was the composite of all-cause mortality or first HF hospitalization. Out of 4753 patients with HF screened, 1149 (24.3%) patients with at least one high-risk 'I NEED HELP' marker were included (mean age 75.1 ± 11.5 years, 67.3% male, median left ventricular ejection fraction [LVEF] 35% [interquartile range 25%-50%]). Among them, 193 (16.8%) patients met the HFA-ESC advanced HF definition. As compared to others, these patients were younger, had lower LVEF, higher natriuretic peptides and a worse clinical profile. The 1-year rate of the primary endpoint was 69.3% in patients with advanced HF according to the HFA-ESC definition versus 41.8% in the others (hazard ratio [HR] 2.23, 95% confidence interval [CI] 1.82-2.74, p < 0.001). The prognostic impact of the HFA-ESC advanced HF definition was confirmed after multivariable adjustment for relevant covariates (adjusted HR 1.98, 95% CI 1.57-2.50, p < 0.001).

CONCLUSIONS

The HFA-ESC advanced HF definition had a strong prognostic impact in a contemporary, real-world, multicentre high-risk cohort of patients with HF.

Suppression of Cardiogenic Edema with Sodium-Glucose Cotransporter-2 Inhibitors in Heart Failure with Reduced Ejection Fraction: Mechanisms and Insights from Pre-Clinical Studies

In heart failure with reduced ejection fraction (HFrEF), cardiogenic edema develops from impaired cardiac function, pathological remodeling, chronic inflammation, endothelial dysfunction, neurohormonal activation, and altered nitric oxide-related pathways. Pre-clinical HFrEF studies have shown that treatment with sodium-glucose cotransporter-2 inhibitors (SGLT-2i) stimulates natriuretic and osmotic/diuretic effects, improves overall cardiac function, attenuates maladaptive cardiac remodeling, and reduces chronic inflammation, oxidative stress, and endothelial dysfunction. Here, we review the mechanisms and effects of SGLT-2i therapy on cardiogenic edema in various models of HFrEF. Overall, the data presented suggest a high translational importance of these studies, and pre-clinical studies show that SGLT-2i therapy has a marked effect on suppressing the progression of HFrEF through multiple mechanisms, including those that affect the development of cardiogenic edema.

Behavioral Interventions for the Patient-Caregiver Unit in Patients with Chronic Heart Failure: A Systematic Review of Caregiver Outcomes

Background

Chronic heart failure (CHF) is a debilitating condition that affects millions worldwide. It is accompanied by a myriad of adverse consequences, such asdiminishing of quality of life and deterioration of mental health. Caregivers play a pivotal role in helping CHF patients manage their conditions and symptoms, as a result the physical, mental and emotional state of caregivers have a direct impact on CHF patients and the management of this condition.

Purpose

This systematic review aims to synthesize data about the effectiveness of behavioral interventions targeted at patients with chronic heart failure (CHF) and/or informal caregivers of CHF patients to improve overall management and treatment of CHF in the population.

Patients and Methods

Three databases were searched for published studies and studies that included evaluated outcomes of interventions that targeted CHF patients or informal caregivers. All randomized controlled trials, trials of either experimental or quasi-experimental design were included. Studies that only involved formal caregivers, patient populations of adolescents/young adults and patients with non-chronic conditions were excluded.

Results

Across the 21 included studies, no study reported a significant improvement in all three domains of quality of life (QoL), depression and loneliness of caregivers while only three studies reported a significant improvement in two outcomes. Within each domain, heterogeneity in measures limited quantitative pooling.

Conclusion

This review provides data on the efficacy of interventions targeted at CHF patients and/or informal caregivers. It also highlights successful interventions and its features. Following this, additional resources need to be invested and directed towards implementing these interventions.

Sodium-Glucose Cotransporter-2 Inhibitors Improve Heart Failure with Reduced Ejection Fraction Outcomes by Reducing Edema and Congestion

Pathological sodium-water retention or edema/congestion is a primary cause of heart failure (HF) decompensation, clinical symptoms, hospitalization, reduced quality of life, and premature mortality. Sodium-glucose cotransporter-2 inhibitors (SGLT-2i) based therapies reduce hospitalization due to HF, improve functional status, quality, and duration of life in patients with HF with reduced ejection fraction (HFrEF) independently of their glycemic status. The pathophysiologic mechanisms and molecular pathways responsible for the benefits of SGLT-2i in HFrEF remain inconclusive, but SGLT-2i may help HFrEF by normalizing salt-water homeostasis to prevent clinical edema/congestion. In HFrEF, edema and congestion are related to compromised cardiac function. Edema and congestion are further aggravated by renal and pulmonary abnormalities. Treatment of HFrEF patients with SGLT-2i enhances natriuresis/diuresis, improves cardiac function, and reduces natriuretic peptide plasma levels. In this review, we summarize current clinical research studies related to outcomes of SGLT-2i treatment in HFrEF with a specific focus on their contribution to relieving or preventing edema and congestion, slowing HF progression, and decreasing the rate of rehospitalization and cardiovascular mortality.

Advanced heart failure: guideline-directed medical therapy, diuretics, inotropes, and palliative care

Heart failure (HF) is a major cause of mortality, hospitalizations, and reduced quality of life and a major burden for the healthcare system. The number of patients that progress to an advanced stage of HF is growing. Only a limited proportion of these patients can undergo heart transplantation or mechanical circulatory support. The purpose of this review is to summarize medical management of patients with advanced HF. First, evidence-based oral treatment must be implemented although it is often not tolerated. New therapeutic options may soon become possible for these patients. The second goal is to lessen the symptomatic burden through both decongestion and haemodynamic improvement. Some new treatments acting on cardiac function may fulfil both these needs. Inotropic agents acting through an increase in intracellular calcium have often increased risk of death. However, in the recent Global Approach to Lowering Adverse Cardiac Outcomes Through Improving Contractility in Heart Failure (GALACTIC-HF) trial, omecamtiv mecarbil was safe and effective in the reduction of the primary outcome of cardiovascular death or HF event compared with placebo (hazard ratio, 0.92; 95% confidence interval, 0.86-0.99; P = 0.03) and its effects were larger in those patients with more severe left ventricular dysfunction. Patients with severe HF who received omecamtiv mecarbil experienced a significant treatment benefit, whereas patients without severe HF did not (P = 0.005 for interaction). Lastly, clinicians should take care of the end of life with an appropriate multidisciplinary approach. Medical treatment of advanced HF therefore remains a major challenge and a wide open area for further research.

Evaluation of CORIN in patients with heart failure: A systematic review and meta-analysis

Objectives: We aim to evaluate the association between CORIN and heart failure.

Methods: This study used PubMed, EMBASE, Cochrane database, and China National Knowledge Database (CNKI) to search for CORIN-related full-text articles with heart failure patients. We drew forest plots, performed sensitivity and bias analyses based on the included data. Next, we used Review Manager 5.2 software to assess the heterogeneity among selected articles.

Results: Our meta-analysis results showed there was significant relationship between CORIN and heart failure (HF). There was significant difference of CORIN between heart failure group and control group (MD = −293.88, 95% confidence interval [-380.26, −207.49], p < .00001; heterogeneity p < .0001, I2= 97%) and there was significant difference in CORIN between ischemic group and non-ischemic group (MD = 88.79, 95% confidence interval [70.46107.12], heterogeneity p < .000, p = 0.94, l2= 0%). In subgroup analysis, there were significant differences in three different HF levels. Limited publication bias was observed, and this study was robust.

Conclusion: In short, the results showed that CORIN was closely related with heart failure and might be helpful in the diagnosis of heart failure.
