The economic burden of heart failure in Denmark from 1998 to 2016

The annual economic burden incurred by heart failure patients in Vietnam: a retrospective analysis

Introduction

Heart failure (HF) is a chronic condition associated with substantial mortality and hospitalisation, resulting in costly inpatient visits. The healthcare systems of several countries, including Vietnam, experience considerable difficulty in dealing with the enormous fiscal burden presented by HF. This study aims to analyse the direct medical costs associated with HF inpatient treatment from the hospital perspective.

Materials and methods

This study retrospectively analysed the electronic medical records of patients diagnosed with HF from 2018 to 2021 at Military Hospital 175 in Vietnam. The sample consisted of 906 hospitalised patients (mean age: 71.2 ± 14.1 years). The financial impact of HF was assessed by examining the direct medical expenses incurred by the healthcare system, and the costs of pharmaceutical categories used in treatment were explored.

Results

The cumulative economic burden of HF from 2018 to 2021 was US$1,068,870, with annual costs ranging from US$201,670 to US$443,831. Health insurance covered 72.7% of these costs. Medications and infusions, and medical supplies accounted for the largest expenses, at 29.8% and 22.1%, respectively. The medication HF group accounted for 13.01% of these expenses, of which the costliest medications included nitrates (2.57%), angiotensin II receptor blockers (0.51%), ivabradine (0.39%), diuretics (0.24%), and mineralocorticoid receptor antagonists (0.23%). Comorbidities and the length of hospital stay significantly influenced annual treatment costs.

Conclusion

The study reveals that HF significantly impacts Vietnam's healthcare system and citizens, requiring a comprehensive understanding of its financial implications and efficient management of medical resources for those diagnosed. This study highlights the substantial economic burden of HF on Vietnam's healthcare system, with medication costs, particularly antithrombotic drugs, representing the largest expense. Most healthcare costs were covered by health insurance, and expenses were significantly influenced by comorbidity and length of hospital stay. These findings can inform healthcare policy, resource allocation and optimise management strategies in Vietnam.

A danish healthcare-focused economic evaluation of first-line cryoballoon ablation versus antiarrhythmic drug therapy for the treatment of paroxysmal atrial fibrillation

INTRODUCTION

Three randomised controlled trials (RCTs) have demonstrated that first-line cryoballoon pulmonary vein isolation decreases atrial tachycardia in patients with symptomatic paroxysmal atrial fibrillation (PAF) compared with antiarrhythmic drugs (AADs). The aim of this study was to develop a cost-effectiveness model (CEM) for first-line cryoablation compared with first-line AADs for the treatment of PAF. The model used a Danish healthcare perspective.

METHODS

Individual patient-level data from the Cryo-FIRST, STOP AF and EARLY-AF RCTs were used to parameterise the CEM. The model structure consisted of a hybrid decision tree (one-year time horizon) and a Markov model (40-year time horizon, with a three-month cycle length). Health-related quality of life was expressed in quality-adjusted life years (QALYs). Costs and benefits were discounted at 3% per year. Model outcomes were produced using probabilistic sensitivity analysis.

RESULTS

First-line cryoablation is dominant, meaning it results in lower costs (-€2,663) and more QALYs (0.18) when compared to first-line AADs. First-line cryoablation also has a 99.96% probability of being cost-effective, at a cost-effectiveness threshold of €23,200 per QALY gained. Regardless of initial treatment, patients were expected to receive ∼ 1.2 ablation procedures over a lifetime horizon.

CONCLUSION

First-line cryoablation is both more effective and less costly (i.e. dominant), when compared with AADs for patients with symptomatic PAF in a Danish healthcare system.

The economic burden of diseases in the Nordic countries: A systematic review

BACKGROUND

Economic burden studies can provide insights into the drivers leading to increasing healthcare costs. It can also provide a more holistic view of how diseases impact the welfare of patients and their families. Having concrete estimates of the economic burden across multiple diseases can help policymakers determine which diseases are economically more burdensome. This study aimed to review and summarise comprehensively economic burden studies across multiple diseases in the Nordic countries between 2000 and 2020.

METHODS

According to the 2020 PRISMA statement, a systematic literature review was conducted in PubMed, CINAHL, Academic Search Premier and Global Health databases using key terms related to the economic burden of any disease in Denmark, Finland, Greenland, Iceland, Norway and Sweden. Grey literature was also reviewed.

RESULTS

A total of 10,050 potential titles and abstracts were identified and screened, and 254 full-text papers that met the inclusion criteria were evaluated by two independent reviewers. Of these, 119 articles were included in a qualitative synthesis. Twenty-nine had clearly defined comparison groups, thus able to attribute the costs to the disease. Large variations concerning methodology and cost components were noted. Across diseases, the economic burden ranged from EUR 1668 per patient annually for chronic obstructive pulmonary disease to EUR 93,041 for multiple sclerosis. However, estimates varied widely, even within each disease.

CONCLUSIONS

Our review highlights the need for more comparable economic burden studies. Future studies should focus on applying robust methodology and homogeneous cost-reporting methods to inform policymakers about which diseases are economically more burdensome.

Cardiovascular events, mortality, early retirement and costs in >50 000 persons with chronic heart failure in Sweden

AIMS

We aimed to examine cardiovascular events (stroke and myocardial infarction [MI]), mortality, early retirement and economic costs over 5 years in people with chronic heart failure (CHF) and matched controls in Sweden.

METHODS AND RESULTS

Individuals (aged ≥16 years) living in Sweden on 1 January 2012 were identified in an existing database. Individuals with CHF were propensity score matched to controls without CHF by birth year, sex and educational status. We analysed risks of stroke, MI, mortality and early retirement, and compared direct costs (inpatient care, outpatient care and drug costs) and indirect costs (work absence). After matching, there were 53 520 individuals in each cohort. In each cohort, mean age was 69.0 years (standard deviation 8.2), and 29.7% of individuals were women. People with CHF were significantly more likely than controls to experience stroke (hazard ratio 1.46 [95% confidence interval 1.38-1.56]) and MI (1.61 [1.51-1.71]). All-cause mortality was nearly three-fold higher (2.89 [2.80-2.98]) and the likelihood of early retirement was more than three-fold higher (3.69 [3.08-4.42]). Total mean annual costs per person were €9663 (standard error 38) for people with CHF, of which 53% were direct costs, and €2845 (standard error 19) for controls, of which 40% were direct costs. In people with CHF, inpatient costs comprised 78% of total annual mean direct costs over follow-up, outpatient costs contributed 15% and drug costs contributed 8%. In controls, the corresponding proportions were 71%, 18% and 11%.

CONCLUSIONS

CHF has a considerable impact on the risk of cardiovascular events and death, early retirement and economic costs. Inpatient admissions and work absence are major contributors to economic costs.

Gut-derived short-chain fatty acids bridge cardiac and systemic metabolism and immunity in heart failure

Heart failure (HF) represents a group of complex clinical syndromes with high morbidity and mortality and has a significant global health burden. Inflammation and metabolic disorders are closely related to the development of HF, which are complex and depend on the severity and type of HF and common metabolic comorbidities such as obesity and diabetes. An increasing body of evidence indicates the importance of short-chain fatty acids (SCFAs) in regulating cardiac function. In addition, SCFAs represent a unique class of metabolites and play a distinct role in shaping systemic immunity and metabolism. In this review, we reveal the role of SCFAs as a link between metabolism and immunity, which regulate cardiac and systemic immune and metabolic systems by acting as energy substrates, inhibiting the expression of histone deacetylase (HDAC) regulated genes and activating G protein-coupled receptors (GPCRs) signaling. Ultimately cardiac efficiency is improved, cardiac inflammation alleviated and cardiac function in failing hearts enhanced. In conclusion, SCFAs represent a new therapeutic approach for HF.

Left Bundle Branch Area Pacing Versus Biventricular Pacing as Initial Strategy for Cardiac Resynchronization

BACKGROUND

Left bundle branch area pacing (LBBAP) for cardiac resynchronization therapy (CRT) is an alternative to biventricular pacing (BiVp).

OBJECTIVES

The purpose of this study was to compare the outcomes between LBBAP and BiVp as an initial implant strategy for CRT.

METHODS

In this prospective multicenter, observational, nonrandomized study, first-time CRT implant recipients with LBBAP or BiVp were included. The primary efficacy outcome was a composite of heart failure (HF)-related hospitalization and all-cause mortality. The primary safety outcomes were acute and long-term complications. Secondary outcomes included postprocedural New York Heart Association functional class and electrocardiographic and echocardiographic parameters.

RESULTS

A total of 371 patients (median follow-up of 340 days [IQR: 206-477 days]) were included. The primary efficacy outcome occurred in 24.2% in the LBBAP vs 42.4% in the BiVp (HR: 0.621 [95% CI: 0.415-0.93]; P = 0.021) group, driven by a reduction in HF-related hospitalizations (22.6% vs 39.5%; HR: 0.607 [95% CI: 0.397-0.927]; P = 0.021) without significant difference in all-cause mortality (5.5% vs 11.9%; P = 0.19) or differences in long-term complications (LBBAP: 9.4% vs BiVp: 15.2%; P = 0.146). LBBAP resulted in shorter procedural (95 minutes [IQR: 65-120 minutes] vs 129 minutes [IQR: 103-162 minutes]; P < 0.001) and fluoroscopy times (12 minutes [IQR: 7.4-21.1 minutes] vs 21.7 minutes [IQR: 14.3-30 minutes]; P < 0.001), shorter QRS duration (123.7 ± 18 milliseconds vs 149.3 ± 29.1 milliseconds; P < 0.001), and higher postprocedural left ventricular ejection fraction (34.1% ± 12.5% vs 31.4% ± 10.8%; P = 0.041).

CONCLUSIONS

LBBAP as an initial CRT strategy resulted in a lower risk of HF-related hospitalizations compared to BiVp. A reduction in procedural and fluoroscopy times, shorter paced QRS duration, and improvements in left ventricular ejection fraction compared with BiVp were observed.

Clinical course and therapy optimization of patients after discharge from a specialized heart failure clinic

Aim: We aimed to describe the clinical course of patients with heart failure with reduced ejection fraction (HFrEF) after discharge from the heart failure clinics (HFC). Patients & methods: We reviewed the hospital's records of 610 patients that were discharged between 2013 and 2018 from the HFC at a single centre. Patients with no recurrent contact to ambulatory cardiac care were invited to an echocardiographic assessment. Results: Of the survivors, 72% were re-referred after discharge. Nearly 30% of the patients with no recurrent contact with ambulatory cardiac care had persistent HFrEF and further therapeutical optimizations were indicated in half of them. Conclusion: This highlights the importance to identify high-risk patients that would benefit from extended management in the HFC.

Global burden of heart failure: a comprehensive and updated review of epidemiology

Heart Failure (HF) is a multi-faceted and life-threatening syndrome characterized by significant morbidity and mortality, poor functional capacity and quality of life, and high costs. HF affects more than 64 million people worldwide. Therefore, attempts to decrease its social and economic burden have become a major global public health priority. While the incidence of HF has stabilized and seems to be declining in industrialized countries, the prevalence is increasing due to the ageing of the population, improved treatment of and survival with ischaemic heart disease, and the availability of effective evidence-based therapies prolonging life in patients with HF. There are geographical variations in HF epidemiology. There is substantial lack of data from developing countries, where HF exhibits different features compared with that observed in the Western world. In this review, we provide a contemporary overview on the global burden of HF, providing updated estimates on prevalence, incidence, outcomes, and costs worldwide.

Patient-reported outcome is associated with health care costs in patients with ischaemic heart disease and arrhythmia

AIMS

Systematic use of patient-reported outcomes (PROs) have the potential to improve quality of care and reduce costs of health care services. We aimed to describe whether PROs in patients diagnosed with heart disease are directly associated with health care costs.

METHODS AND RESULTS

A national cross-sectional survey including PROs at discharge from a heart centre with 1-year follow-up using data from national registers. We included patients with either ischaemic heart disease (IHD), arrhythmia, heart failure (HF), or valvular heart disease (VHD). The Hospital Anxiety and Depression Scale, the heart-specific quality of life, the EuroQol five-dimensional questionnaire, and the Edmonton Symptom Assessment Scale were used. The economic analysis was based on direct costs including primary, secondary health care, and medical treatment. Patient-reported outcomes were available from 13 463 eligible patients out of 25.241 [IHD (n = 7179), arrhythmia (n = 4322), HF (n = 987), or VHD (n = 975)]. Mean annual total direct costs in all patients were €23 228 (patients with IHD: €19 479, patients with arrhythmia: €21 076, patients with HF: €34 747, patients with VDH: €48 677). Hospitalizations contributed overall to the highest part of direct costs. For patients discharged with IHD or arrhythmia, symptoms of anxiety or depression, worst heart-specific quality of life or health status, and the highest symptom burden were associated with increased economic expenditure. We found no associations in patients with HF or VHD.

CONCLUSION

Patient-reported outcomes at discharge from a heart centre were associated with direct health care costs in patients with IHD and arrhythmia.

Signaling cascades in the failing heart and emerging therapeutic strategies

Chronic heart failure is the end stage of cardiac diseases. With a high prevalence and a high mortality rate worldwide, chronic heart failure is one of the heaviest health-related burdens. In addition to the standard neurohormonal blockade therapy, several medications have been developed for chronic heart failure treatment, but the population-wide improvement in chronic heart failure prognosis over time has been modest, and novel therapies are still needed. Mechanistic discovery and technical innovation are powerful driving forces for therapeutic development. On the one hand, the past decades have witnessed great progress in understanding the mechanism of chronic heart failure. It is now known that chronic heart failure is not only a matter involving cardiomyocytes. Instead, chronic heart failure involves numerous signaling pathways in noncardiomyocytes, including fibroblasts, immune cells, vascular cells, and lymphatic endothelial cells, and crosstalk among these cells. The complex regulatory network includes protein-protein, protein-RNA, and RNA-RNA interactions. These achievements in mechanistic studies provide novel insights for future therapeutic targets. On the other hand, with the development of modern biological techniques, targeting a protein pharmacologically is no longer the sole option for treating chronic heart failure. Gene therapy can directly manipulate the expression level of genes; gene editing techniques provide hope for curing hereditary cardiomyopathy; cell therapy aims to replace dysfunctional cardiomyocytes; and xenotransplantation may solve the problem of donor heart shortages. In this paper, we reviewed these two aspects in the field of failing heart signaling cascades and emerging therapeutic strategies based on modern biological techniques.

Elevated urinary albumin concentration predicts worse clinical outcomes in hospitalized acute decompensated heart failure patients

Objective

To investigate the prognostic value of elevated urinary albumin concentration (UAC) in hospitalized acute decompensated heart failure (ADHF) patients.

Methods

We measured UAC at baseline in 1818 hospitalized ADHF patients who were admitted to our Heart Failure Center. All patients were followed up for a median period of 937.5 days. The primary endpoint was a composite of all‐cause death or heart transplantation (HTx) or left ventricular assist device (LVAD) implantation.

Results

In total, 41.5% of ADHF patients had albuminuria (UAC ≥ 20 mg/L). The median value of UAC was 15.5 mg/L. A total of 679 patients died or underwent HTx/LVAD during follow‐up. The median UAC was significantly lower in non‐HTx/LVAD survivors (14.3 mg/L) than in those who died or underwent HTx/LVAD (18.0 mg/L, P < 0.001). Compared with patients without albuminuria (reference, n = 1064), those with albuminuria had a 1.47‐fold higher risk of all‐cause death or HTx/LVAD (95% confidence interval [CI]:1.26–1.71, P < 0.001), with hazard ratios (HRs) of 1.42 (95% CI: 1.21–1.66) and 1.74 (95% CI: 1.33–2.26) in patients with microalbuminuria (20 mg/L ≤ UAC < 200 mg/L, n = 617) and macroalbuminuria (UAC ≥ 200 mg/L, n = 137), respectively (both P < 0.001). After adjustment for significant clinical risk factors, the albuminuria group had a higher risk of primary adverse events than the non‐albuminuria group (HR = 1.28, 95% CI: 1.09–1.50, P = 0.003), with HRs of 1.27 [95% CI: 1.07–1.49] and 1.36 [95% CI: 1.01–1.84] in patients with microalbuminuria and macroalbuminuria, respectively (P = 0.006 and P = 0.041). The adjusted risk of primary adverse events also increased with the degree of albuminuria in the test for trend (HR = 1.21, 95% CI: 1.06–1.37, P for trend = 0.004). In the subgroup analysis, albuminuria had a significantly greater prognostic value for patients with left ventricular ejection fraction ≥ 40%, eGFR ≥ 60 mL/min/1.73 m², BUN/creatinine ratio ≥ 20 or NT‐proBNP < 2098 pg/mL.

Conclusion

The presence of albuminuria evaluated by UAC predicts adverse clinical outcomes in hospitalized ADHF patients.

Heart failure in the last year: progress and perspective

Research about heart failure (HF) has made major progress in the last years. We give here an update on the most recent findings. Landmark trials have established new treatments for HF with reduced ejection fraction. Sacubitril/valsartan was superior to enalapril in PARADIGM-HF trial, and its initiation during hospitalization for acute HF or early after discharge can now be considered. More recently, new therapeutic pathways have been developed. In the DAPA-HF and EMPEROR-Reduced trials, dapagliflozin and empagliflozin reduced the risk of the primary composite endpoint, compared with placebo [hazard ratio (HR) 0.74; 95% confidence interval (CI) 0.65-0.85; P < 0.001 and HR 0.75; 95% CI 0.65-0.86; P < 0.001, respectively]. Second, vericiguat, an oral soluble guanylate cyclase stimulator, reduced the composite endpoint of cardiovascular death or HF hospitalization vs. placebo (HR 0.90; 95% CI 0.82-0.98; P = 0.02). On the other hand, both the diagnosis and treatment of HF with preserved ejection fraction, as well as management of advanced HF and acute HF, remain challenging. A better phenotyping of patients with HF would be helpful for prognostic stratification and treatment selection. Further aspects, such as the use of devices, treatment of arrhythmias, and percutaneous treatment of valvular heart disease in patients with HF, are also discussed and reviewed in this article.

Left ventricular systolic ejection time is an independent predictor of all-cause mortality in heart failure with reduced ejection fraction

AIMS

Colour tissue Doppler imaging (TDI) M-mode through the mitral leaflet is an easy and precise method to obtain cardiac time intervals including isovolumic contraction time (IVCT), isovolumic relaxation time (IVRT) and systolic ejection time (SET). The myocardial performance index (MPI) is defined as [(IVCT + IVRT)/SET]. Whether cardiac time intervals obtained by the TDI M-mode method can be used to predict outcome in patients with heart failure with reduced ejection fraction (HFrEF) remains unknown.

METHODS AND RESULTS

A total of 997 patients with HFrEF (mean age 67 ± 11 years, 74% male) underwent an echocardiographic examination including TDI. During a median follow-up of 3.4 years (interquartile range 1.9-4.8 years), 165 (17%) patients died. The risk of mortality increased by 9% per 10 ms decrease in SET [per 10 ms decrease: hazard ratio (HR) 1.09, 95% confidence interval (CI) 1.06-1.13; P < 0.001]. The association remained significant even after multivariable adjustment for clinical and echocardiographic parameters (per 10 ms decrease: HR 1.06, 95% CI 1.01-1.11; P = 0.030). The MPI was a significant predictor in an unadjusted model (per 0.1 increase: HR 3.06, 95% CI 1.16-8.06; P = 0.023). However, the association did not remain significant after multivariable adjustment. No significant associations between IVCT or IVRT and mortality were found in unadjusted nor adjusted models. Additionally, SET provided incremental prognostic information with regard to predicting mortality when added to established clinical predictors of mortality in patients with HFrEF.

CONCLUSION

In patients with HFrEF, SET provides independent and incremental prognostic information regarding all-cause mortality.

Diagnostic and lifetime hospital costs of patients suffering from wild-type transthyretin amyloid cardiomyopathy in Denmark

AIMS

Wild-type transthyretin amyloid cardiomyopathy (ATTRwt) is a fast progressing and fatal disease associated with substantial delays in diagnosis. Between the first symptoms and diagnosis, patients are frequently hospitalized, primarily with cardiac symptoms. After diagnosis, patients continue to experience frequent hospital admissions. The objective of this study was to estimate the Danish diagnostic and lifetime hospital costs associated with the treatment of patients with ATTRwt both before and after they are diagnosed.

MATERIALS AND METHODS

We developed a cost model for Danish hospital costs associated with ATTRwt, including the costs of diagnosis, cardiac implants, and hospital admissions covering inpatient hospitalization and outpatient hospital care (ambulatory and emergency services). The number of diagnoses, cardiac implants, inpatient hospitalization and outpatient hospital care were estimated based on published data. Estimates of the unit costs were based on publicly available Danish reference costs. We calculated the total hospital costs covering the median lifespan of patients from onset of symptoms, which is 13 months prior to diagnosis, to 52 months after diagnosis which is the median survival time after diagnosis.

RESULTS

The average cost of diagnosing ATTRwt was USD 3,424 per patient; the average costs of cardiac implants were USD 1,851 per patient. Hospital admissions costs totaled USD 3,345 pre-diagnosis and USD 59,449 post-diagnosis per patient, on average. The total diagnostic and lifetime (65 months) hospital costs associated with ATTRwt were USD 68,069.

CONCLUSIONS

Caring for patients with ATTRwt places a significant economic burden on the healthcare system. The study emphasizes the cost saving potential for medical interventions in this patient population.

Inequalities in heart failure care in a tax-financed universal healthcare system: a nationwide population-based cohort study

Aims

Data on socioeconomic‐related differences in heart failure (HF) care are sparse. Inequality in care may potentially contribute to a poor clinical outcome. We examined socioeconomic‐related differences in quality of HF care among patients with incident HF with reduced ejection fraction (EF) (HFrEF).

Methods and results

We conducted a nationwide population‐based cohort study among patients with HFrEF (EF ≤40%) registered from January 2008 to October 2015 in the Danish Heart Failure Registry, a nationwide registry of patients with a first‐time primary HF diagnosis. Associations between individual‐level socioeconomic factors (cohabitation status, education, and family income) and the quality of HF care defined by six guideline‐recommended process performance measures [New York Heart Association (NYHA) classification, treatment with angiotensin‐converting‐enzyme inhibitors (ACEI)/angiotensin receptor blockers (ARB), beta‐blockers and mineralocorticoid receptor antagonists, exercise training, and patient education] were assessed using multiple imputation and multivariable logistic regression controlling for potential confounders. Among 17 122 HFrEF patients included, 15 290 patients had data on all six process performance measures. Living alone was associated with lower odds of NYHA classification [adjusted OR (aOR) 0.81; 95% confidence interval (CI): 0.72–0.90], prescription of ACEI/ARB (aOR 0.76; 95% CI: 0.68–0.88) and beta‐blockers (aOR 0.84; 95% CI: 0.76–0.93), referral to exercise training (aOR 0.75; 95% CI: 0.69–0.81), and patient education (aOR 0.73; 95% CI: 0.67–0.80). Compared with high‐level education, low‐level education was associated with lower odds of NYHA classification (aOR 0.93; 95% CI: 0.79–1.11), treatment with ACEI/ARB (aOR 0.99; 95% CI: 0.81–1.20) and beta‐blockers (aOR 0.93; 95% CI: 0.79–1.09), referral to exercise training (aOR 0.73; 95% CI: 0.65–0.82), and patient education (aOR 0.86, 95% CI: 0.75–0.98). An income in the lowest tertile was associated with lower odds of NYHA classification (aOR 0.67; 95% CI: 0.58–0.79), prescription of ACEI/ARB (aOR 0.80, 95% CI: 0.67–0.95) and beta‐blockers (aOR 0.88, 95% CI: 0.86–1.01), referral to exercise training (aOR 0.59, 95% CI: 0.53–0.64), and patient education (aOR 0.66; 95% CI: 0.59–0.74) compared with an income in the highest tertile. Overall, no systematic differences were seen when the analyses were stratified by sex and age groups.

Conclusions

Living alone, low‐level education, and income in the lowest tertile were associated with reduced use of recommended processes of HF care among Danish HFrEF patients with a first‐time primary HF diagnosis. Efforts are warranted to ensure guideline‐recommended HF care to all HFrEF patients, irrespective of socioeconomic background.
