Heart failure with Sarcopenia: A Bibliometric review from 1995 to 2022

This study aimed to dynamically track the priorities and potential research hotspots in the field of heart failure with sarcopenia. Using CiteSpace, we analyzed the literature on heart failure with sarcopenia from the Web of Science database from 1995 to 2022. The analysis encompassed 507 records, revealing an overall upward trend in annual publication volume. Europe and the United States emerged as the primary regions for publishing, particularly driven by contributions from developed countries such as the United States, Germany, and Italy. Productive institutions included the Charite Universitatsmedizin Berlin, University Medical Center Gottingen, the German Center for Cardiovascular Research (DZHK), Universita Cattolica del Sacro Cuore, and the National Institute on Aging (NIA). Noteworthy academic groups have formed around these institutions; von Haehling S, Anker Stefan D, Springer J, and Doehner W frequently collaborated. The core journals that frequently published articles in this area included Circulation, European Heart Journal, and The Journals of Gerontology Series A-Biological Sciences and Medical Sciences. Based on the keyword analysis, we identified three key research areas. First, the diagnosis and definition of sarcopenia emerged as significant themes. Second, researchers have focused on exploring the mechanisms underlying heart failure with sarcopenia, including inflammation, insulin resistance, and oxidative stress. Finally, treatment strategies, such as physical activity and nutritional support, constitute another critical research theme. Furthermore, potential research hotspots within this field include clinical randomized controlled trials, investigations into inflammatory mechanisms, cardiac rehabilitation, studies on physical activity, androgen receptor modulators, and investigations into clinical outcomes such as cognitive impairment.

Importance analysis of psychosociological variables in frailty syndrome in heart failure patients using machine learning approach

The prevention and diagnosis of frailty syndrome (FS) in cardiac patients requires innovative systems to support medical personnel, patient adherence, and self-care behavior. To do so, modern medicine uses a supervised machine learning approach (ML) to study the psychosocial domains of frailty in cardiac patients with heart failure (HF). This study aimed to determine the absolute and relative diagnostic importance of the individual components of the Tilburg Frailty Indicator (TFI) questionnaire in patients with HF. An exploratory analysis was performed using machine learning algorithms and the permutation method to determine the absolute importance of frailty components in HF. Based on the TFI data, which contain physical and psychosocial components, machine learning models were built based on three algorithms: a decision tree, a random decision forest, and the AdaBoost Models classifier. The absolute weights were used to make pairwise comparisons between the variables and obtain relative diagnostic importance. The analysis of HF patients' responses showed that the psychological variable TFI20 diagnosing low mood was more diagnostically important than the variables from the physical domain: lack of strength in the hands and physical fatigue. The psychological variable TFI21 linked with agitation and irritability was diagnostically more important than all three physical variables considered: walking difficulties, lack of hand strength, and physical fatigue. In the case of the two remaining variables from the psychological domain (TFI19, TFI22), and for all variables from the social domain, the results do not allow for the rejection of the null hypothesis. From a long-term perspective, the ML based frailty approach can support healthcare professionals, including psychologists and social workers, in drawing their attention to the non-physical origins of HF.

Impairment in activities of daily living and readmission in older patients with heart failure: a cohort study

OBJECTIVES

This study aims to investigate the prevalence of impairment of activities of daily living (ADLs) in older patients with heart failure (HF), and to examine the impact of ADL impairment on readmission after discharge.

DESIGN AND SETTINGS

A prospective cohort study was conducted in patients aged ≥65 years with HF admitted to a tertiary hospital in Vietnam from August 2016 to June 2017. Difficulties with six ADLs were assessed by a questionnaire. Participants were classified into two categories (with and without ADL impairment). The associations of ADL impairment with 3-month readmission were examined using logistic regression models.

RESULTS

There were 180 participants (mean age 80.6±8.2, 50% female) and 26.1% were classified as having ADL impairment. The most common impaired activity was bathing (21.1%), followed by transferring (20.0%), toileting (12.2%), dressing (8.9%), eating (3.3%), and continence (2.8%). During 3-month follow-up, 32.8% of the participants were readmitted to hospitals (55.3% in participants with ADL impairment, 24.8% in those without ADL impairment, p<0.001). ADL impairment significantly increased the risk of 3-month readmission (adjusted OR 2.75, 95% CI 1.25 to 6.05, p=0.01).

CONCLUSIONS

In summary, ADL impairment was common in older hospitalised patients with HF and was associated with increased readmission. These findings suggest further studies on ADL assessment and intervention during transition care for older patients with HF after discharge to prevent readmission.

Association between heart diseases, social factors and physical frailty in community-dwelling older populations: The septuagenarians, octogenarians, nonagenarians investigation with centenarians study

AIM

Heart diseases and social factors are associated with physical frailty, but there are few studies of older people living in the community. Consequently, the aim of this study was to examine the association between heart diseases, social factors and physical frailty in community-dwelling older populations including the oldest-old people.

METHODS

The cross-sectional study included 1882 participants of community-dwelling older and oldest-old people. The survey site assessed questionnaires on medical history, social factors, blood samples and physical examination. Physical frailty was based on slow gait speed or weak grip strength. Associations were analyzed using multiple logistic regression with adjustments for covariate factors.

RESULTS

Subjects with heart disease had a higher prevalence of physical frailty than those without heart disease. After adjusting the covariate factors, heart diseases were associated with a slow gait speed (odds ratio [OR] = 1.62; 95% confidence interval [CI]: 1.13-2.32, P = 0.009). Frequency of going outdoors and direct interaction with relatives or friends were associated with a slow gait speed (OR = 0.83, 95% CI 0.75-0.91, P ≤ 0.001 and OR = 0.87, 95% CI 0.81-0.94, P < 0.001), and associated with physical frailty (OR = 0.80, 95% CI 0.72-0.89, P ≤ 0.001 and OR = 0.88, 95% CI 0.82-0.95, P = 0.002). Living alone and frequency of direct interaction with relatives or friends were associated with physical frailty in subjects with heart disease.

CONCLUSIONS

Our findings indicate that in community-dwelling older people, heart diseases and social factors were associated with physical frailty. Older people with heart disease, those living alone and the frequency of direct interaction with relatives or friends were associated with physical frailty. Geriatr Gerontol Int 2020; 20: 974-979.

Symptom Perception and Influencing Factors in Chinese Patients with Heart Failure: A Preliminary Exploration

A growing body of evidence supports the fact that optimal health-related quality of life is largely dependent on patient competence in symptom perception. However, many studies have reported poor symptom perception in patients with heart failure. In China, there has been no previous research on assessing the symptom perception ability of patients with heart failure. This study aimed to describe how Chinese patients with heart failure perceive their symptoms, as well as to explore their influencing factors. A theory-based, descriptive, correlational cross-sectional design was used in this study. Data on symptom perception and factors related to symptom perception were collected via structured interviews and medical records. A convenience sample of 208 hospitalized patients was enrolled. The degree of symptom perception in this study was at a high level. The results showed that the level of depression, the New York Heart Association functional class, the left ventricular ejection fraction, and educational background were identified as independent factors of symptom perception in Chinese patients with heart failure. The degree of symptom perception of patients with heart failure was affected by personal, psychological, and physiological factors. Health policy and healthcare providers should pay more attention and deepen the understanding to Chinese patients with heart failure to provide better healthcare.

Comparison of the extent and pattern of cognitive impairment among predialysis, dialysis and transplant patients: A cross-sectional study from Australia

AIM

The aim of this study was to compare the extent of cogntive impairment and the types of cognitive deficits in an Australian cohort of four patient groups with end stage kidney disease. Characteristics predicting the presence of cognitive impairment were also evaluated.

METHODS

Observational cross-sectional study of 155 patients with end stage kidney disease are recruited from a regional Australian renal unit. Eligible participants included those whose estimated Glomerular Filtration Rate was < 30 ml/min per 1.73 m² , were undertaking peritoneal or haemodialysis, or had received a kidney transplant. The Montreal Cognitive Assessment tool was used to screen the study participants for cognitive impairment and evaluate cognitive deficits. Cognitive impairment was defined as a total Montreal Cognitive Assessment tool score ≤24/30.

RESULTS

The extent of cognitive impairment varied between the four groups with end stage kidney disease. Factors predicting the presence of cognitive impairment included undertaking dialysis, age ≥65, male gender and the presence of diabetes or cerebrovascular disease. Deficits in executive function, attention, language, visuospatial skills, memory and orientation were common among the study participants, and the extent of these deficits varied between groups. Limitations to the study included the cross-sectional design, and that the presence of confounders like depression were not recorded.

CONCLUSION

The impact of disparities in the cognitive capabilities identified in this study are likely to be far reaching. Tailoring of education and self-management programmes to the cognitive deficits of individuals is required.

Unanswered Questions in Contemporary Heart Failure

OBJECTIVE

The epidemiology of heart failure (HF) is changing. This study aimed to describe questions that arise during the routine care of HF patients that are unanswered by the current literature and describe how the type and focus of these questions has changed over time.

METHODS

Investigators from the National Heart, Lung, and Blood Institute-sponsored Heart Failure Apprentice Network collected and categorized questions from 5 academic hospitals over 12 months. A total of 174 unanswered questions were collected and analyzed.

RESULTS

Compared with 2004, there were more unanswered questions about "whether" to use therapies and fewer about "how" to use therapies. There were fewer questions about what therapeutic targets, therapy adjustment, and combination therapies. There were more questions about whether or how to stop therapies and how to add therapies back. Newly prominent topics, not observed in 2004, including novel therapeutics, refractory ventricular tachycardia, right heart failure, and nutrition/frailty, accounted for 24% of questions.

CONCLUSIONS

Compared with 2004, there are fewer unanswered questions about how to use, adjust, and combine therapies. There were more unanswered questions about whether and how to stop therapies. Almost 25% of unanswered questions dealt with topics indicative of more advanced disease which were not observed in 2004.

Can a Left Ventricular Assist Device in Individuals with Advanced Systolic Heart Failure Improve or Reverse Frailty?

BACKGROUND/OBJECTIVES

Frailty, characterized by low physiological reserves, is strongly associated with vulnerability to adverse outcomes. Features of frailty overlap with those of advanced heart failure, making a distinction between them difficult. We sought to determine whether implantation of a left ventricular assist device (LVAD) would decrease frailty.

DESIGN

Prospective, cohort study.

SETTING

Five academic medical centers.

PARTICIPANTS

Frail individuals (N = 29; mean age 70.6 ± 5.5, 72.4% male).

MEASUREMENTS

Frailty, defined as having 3 or more of the Fried frailty criteria, was assessed before LVAD implantation and 1, 3, and 6 months after implantation. Other domains assessed included quality of life, using the Kansas City Cardiomyopathy Questionnaire; mood, using the Patient Health Questionnaire; and cognitive function, using the Trail-Making Test Part B.

RESULTS

After 6 months, three subjects had died, and one had undergone a heart transplant; of 19 subjects with serial frailty measures, the average number of frailty criteria decreased from 3.9 ± 0.9 at baseline to 2.8 ± 1.4 at 6 months (P = .003). Improvements were observed after 3 to 6 months of LVAD support, although 10 (52.6%) participants still had 3 or more Fried criteria, and all subjects had at least one at 6 months. Changes in frailty were associated with improvement in QOL but not with changes in mood or cognition. Higher estimated glomerular filtration rate at baseline was independently associated with a decrease in frailty.

CONCLUSION

Frailty decreased in approximately half of older adults with advanced heart failure after 6 months of LVAD support. Strategies to enhance frailty reversal in this population are worthy of additional study.

Managing Heart Failure in Long-Term Care: Recommendations from an Interprofessional Stakeholder Consultation

Insuffisance cardiaque (IC) affecte autant que 20 pour cent des résidents en soins de longue durée (SLD), et est associée à la morbidité substantielle, la mortalité et l’utilisation des services de santé. L’objectif de notre étude était de formuler des recommandations sur la mise en œuvre de processus pour prendre soin de l’insuffisance cardiaque dans SLD. Un processus de consultation itérative triphasé avec les parties prenantes a été guidé par la participation d’un panel d’experts et a servi à élaborer des recommandations. Dix-sept recommandations ont été faites. Éléments clés des celles-ci se concentrent sur l’amélioration de la communication interprofessionnelle et accroître les connaissances relatives à l’insuffisance cardiaque entre tous les intervenants dans SLD. Des recommandations systématiques incluent améliorer la communication entre les foyers de SLD et soins aigus et autres prestataires de santé externes, et développer des interventions dans l’ensemble des installations afin de réduire les apports de sodium alimentaire et d’augmenter l’activité physique.

Neuropsychological functioning in heart transplant candidates

OBJECTIVE

This study provides age stratified neuropsychological test data for a large sample of heart transplant candidates. Patients with and without neurological co-morbidities were compared to better isolate the effects of congestive heart failure (CHF) on brain functioning.

METHOD

Between 1988 and 2011, 956 patients (717 males, 239 females) with end-stage CHF and other life threatening cardiac diseases underwent neuropsychological assessment as a requirement of the heart transplant workup. Intellectual, memory, executive, language, attentional and psychomotor abilities were assessed, and standard cardiac measures were concurrently collected. Independent t-tests were used to compare subgroups with and without neurological co-morbidities on cardiac, neuropsychological and MMPI-2 measures. Chi-square tests were used for categorical items to compare demographic data between the two groups.

RESULTS

Significant cognitive impairments across all domains assessed were typical in all age groups. Neurological co-morbidities, such as CVA and cardiac arrest were common, with 28% of the sample having one or more condition. That subgroup scored lower on measures of processing speed, memory, and executive measures, but the pattern of deficits was similar for both groups and not explainable by depression. Depression prevalence per MMPI-2 findings was comparable to that of the general population.

CONCLUSIONS

End stage heart disease/heart failure is associated with global, mild to moderate cognitive impairment, regardless of age or neurological co-morbidities. Contributing factors likely include cerebrovascular hypoperfusion, multiorgan failure, systemic co-morbidities, and lifestyle issues.

Heart Failure Among Older Adults in Skilled Nursing Facilities: More of a Dilemma Than Many Now Realize

Post-acute care, encompassing long-term care hospitals, home health, inpatient rehabilitation, and skilled nursing facilities, is increasingly employed as an integral part of management for more complicated patients, particularly as hospitals seek to maintain costs and decrease length of stay. Skilled nursing facilities (SNFs) in particular are progressively utilized for patients with complex medical processes, including today's growing population of older hospitalized heart failure (HF) patients who pose a prominent challenge due to their high risks of mortality, 30-day readmissions, and substantial aggregate cost burden to the healthcare system. Publications to date have largely grouped post-hospitalized HF patients together when reporting demographic or outcome data, without differentiating those at SNFs from those at traditional nursing homes or other post-acute care settings. SNF patients suffer distinctive vulnerabilities and needs, and understanding these distinctions has implications for determining goals of care. In this review we evaluate HF patients referred to SNFs, and discuss the characteristics, outcomes, and management challenges associated with this particular population.

Frailty and the risk of cognitive impairment

Aging occurs as a series of small steps, first causing cellular damage and then affecting tissues and organs. This is also true in the brain. Frailty, a state of increased risk due to accelerated deficit accumulation, is robustly a risk factor for cognitive impairment. Community-based autopsy studies show that frail individuals have brains that show multiple deficits without necessarily demonstrating cognitive impairment. These facts cast a new light on the growing number of risk factors for cognitive impairment, suggesting that, on a population basis, most health deficits can be associated with late-life cognitive impairment. The systems mechanism by which things that are bad for the body are likely to be bad for the brain can be understood like this: the burden of health deficits anywhere indicates impaired ability to withstand or repair endogenous and environmental damage. This in turn makes additional damage more likely. If true, this suggests that a life course approach to preventing cognitive impairment is desirable. Furthermore, conducting studies in highly selected, younger, healthier individuals to provide ‘proof of concept’ information is now common. This strategy might exclude the very circumstances that are required for disease expression in the people in whom dementia chiefly occurs (that is, older adults who are often in poor health).

Self-concepts of exercise in frail older adults with heart failure: a literature review

The co-occurrence of frailty and heart failure (HF) in older adults (65 years or older) can adversely affect the ability to engage in self-care management behaviors, which may alter self-concepts and decrease quality of life. Little is known about how frailty and HF influence older adults' self-concepts or how these self-concepts affect exercise behaviors. Therefore, the aims of this literature review were to identify the self-concepts of older frail adults with HF and to identify how these self-concepts affect their exercise behaviors. Guided by the schema model of self-concept, publications before April 2013 that examined the impact of the self-concepts of older adults with HF and/or frailty on exercise behavior were reviewed. As a result, 6 articles were included. Three of the 6 articles focused on frailty, and 3 of the 6 articles focused on HF. However, no study was found that specifically examined the self-concepts of frail older adults with HF. The self-concepts of older adults with HF and/or frailty are multifaceted and include both cognitive resources (facilitating exercise) and cognitive liabilities (hindering exercise). Studies are needed to determine how the co-occurrence of frailty and HF impact self-concepts and exercise behaviors in older adults.

Cognitive impairment in heart failure patients

Cognitive damage in heart failure (HF) involves different domains thus interfering with the ability for single patient to self-care and to cope with treatment regimens, modifying symptoms and health behaviours. Many cerebral and functional changes were detected in brain imaging, involving areas of both grey and white matter deputed to cognition. Although various instruments are available to explore cognition, no consensus was obtained on better tools to be used in HF population. Reduction in cerebral blood flow, decreased cardiac output, alterations of cerebrovascular reactivity and modification of blood pressure levels are the main features involved in the etiopathogenetic mechanisms of cognitive deficit. Several cardiac variables, laboratory parameters, demographic and clinical elements were studied for their possible relation with cognition and should be properly evaluated to define patients at increased risk of impairment. The present review gathers available data pointing out assured information and discussing possible areas of research development.

The journey of the frail older adult with heart failure: implications for management and health care systems

The heart failure epidemic predominantly affects older people, particularly those with concurrent co-morbid conditions and geriatric syndromes. Mortality and heath service utilization associated with heart failure are significant, and extend beyond the costs associated with acute care utilization. Over time, older people with heart failure experience a journey characterized by gradual functional decline, accelerated by unpredictable disease exacerbations, requiring greater support to remain in the community, and often ultimately leading to institutionalization. In this narrative review, we posit that the rate of functional decline and associated health care resource utilization can be attenuated by optimizing the management of heart failure and associated co-morbidities. However, to realize this objective, the manner in which care is delivered to frail older people with heart failure must be restructured, from the bedside to the level of the health care system, in order to optimally anticipate, diagnose and manage co-morbidities.

Aerobic exercise as an adjunct therapy for improving cognitive function in heart failure

Persons with heart failure (HF) are typically older and are at a much higher risk for developing cognitive impairment (CI) than persons without HF. Increasingly, CI is recognized as a significant, independent predictor of worse clinical outcomes, more frequent hospital readmissions, and higher mortality rates in persons with HF. CI can have devastating effects on ability to carry out HF effective self-care behaviors. If CI occurs, however, there are currently no evidence based guidelines on how to manage or improve cognitive function in this population. Improvement in cognition has been reported following some therapies in HF and is thought to be the consequence of enhanced cerebral perfusion and oxygenation, suggesting that CI may be amenable to intervention. Because there is substantial neuronal loss with dementia and no effective restorative therapies, interventions that slow, reverse, or prevent cognitive decline are essential. Aerobic exercise is documented to increase cerebral perfusion and oxygenation by promoting neuroplasticity and neurogenesis and, in turn, cognitive functioning. Few studies have examined exercise as a potential adjunct therapy for attenuating or alleviating cognitive decline in HF. In this review, the potential benefit of aerobic exercise on cognitive functioning in HF is presented along with future research directions.

Management considerations in the care of elderly heart failure patients in long-term care facilities

ABSTRACT: 

Heart failure, a condition that affects up to 20% of older persons residing in long-term care facilities, is an important cause of morbidity, health service utilization and death. Effective and interprofessional heart failure care processes could potentially improve care, outcomes and quality of life and delay decline or hospital admission. This article reviews the clinical aspects of heart failure, and the challenges to the diagnosis and management of this condition in long-term care residents who are frail and are affected by multiple comorbidities.

The 2013 Canadian Cardiovascular Society Heart Failure Management Guidelines Update: focus on rehabilitation and exercise and surgical coronary revascularization

The 2013 Canadian Cardiovascular Society Heart Failure Management Guidelines Update provides focused discussions on the management recommendations on 2 topics: (1) exercise and rehabilitation; and (2) surgical coronary revascularization in patients with heart failure. First, all patients with stable New York Heart Association class I-III symptoms should be considered for enrollment in a tailored exercise training program, to improve exercise tolerance and quality of life. Second, selected patients with suitable coronary anatomy should be considered for bypass graft surgery. As in previous updates, the topics were chosen in response to stakeholder feedback. The 2013 Update also includes recommendations, values and preferences, and practical tips to assist the clinicians and health care workers manage their patients with heart failure.

Cognitive function and self-care management in older patients with heart failure

AIMS

People with heart failure have difficulty with self-care management. We do not know if patients with heart failure have difficulty with self-care management due to underlying, mild cognitive impairment (MCI). The purpose of this study was to determine whether MCI, as identified on a simple screening tool, is significantly associated with self-care management in a sample of community dwelling older patients with heart failure.

METHODS AND RESULTS

Using a cross-sectional design, heart failure patients (n=100, mean age 72 SD 10 years) attending an outpatient heart failure clinic completed the Montreal Cognitive Assessment tool (MoCA), Self-Care in Heart Failure Index (SCHFI) and Geriatric Depression Scale. The presence of MCI, as defined by a MoCA score <26, was present in 73% patients; 21% had an adequate self-care management SCHFI score; and 12% reported symptoms of depression. Participants with a MoCA score <26 vs. ≥ 26 scored significantly lower on the self-care management subscale of the SCHFI (48.1 SD 24 vs. 59.3 SD 22 respectively, p=0.035). Using backward regression, the final model was fitted to self-care management while controlling for age and sex and was significant, with (F= 7.04 df (3, 96), and p<0.001), accounting for 18% of the total variance in self-care management (R (2) = 18.03%). The MoCA score was the only variable which remained in the model significantly with p= 0.001.

CONCLUSION

Findings from this study highlight the difficulty older heart failure patients have with self-care management and the need to include formal screening for MCI when exploring variables contributing to self-care management in heart failure patients.
