Physical Rehabilitation for Older Patients Hospitalized for Heart Failure

Exercise interventions for older patients with frailty and heart failure: A scoping review

BACKGROUND

To provide a structured analysis of exercise interventions and outcome measures in older patients with frailty and heart failure (HF).

METHODS

8 databases were searched up to May 22, 2024 to identify relevant studies. Two independent reviewers assessed and collected data according to the TIDieR checklist, CONTENT scale and COMET outcome taxonomy.

RESULTS

We screened 1,253 articles, resulting in 8 articles being included in the scoping review. Aerobic exercise and resistance training were fundamental elements of exercise rehabilitation, with balance training also being essential. Most exercise interventions are individualized, with the type and intensity of exercise being set and adjusted according to the patient's actual condition. However, the tailoring process of resistance training, including exercise load, sets, and repetitions, needs to be more detailed in most studies. The exercise interventions were provided by qualified therapists in most studies, and various methods were taken to ensure fidelity. None of the studies mentioned their theoretical basis. Only two exercise interventions were considered therapeutically valid. The two most commonly reported outcomes were physical function and quality of life.

CONCLUSIONS

It is necessary to focus on addressing research heterogeneity and report transparency to better implement exercise interventions in older frail adults with HF.

Length of stay and prior heart failure admission in frailty and heart failure: A systematic review and meta-analysis

AIMS

The aim of this study was to compare the differences in length of stay (LoS) and prior hospitalization due to heart failure (HHF) in patients with HF and frailty versus without frailty.

METHODS AND RESULTS

From inception until August 2024, PubMed, Scopus, Web of Science and Cochrane Library were searched. To examine the association related to LoS and HHF in patients with HF, a meta-analysis using a random-effects model was conducted (CRD42024570604). Our main analysis demonstrated a significantly increased LoS in patients with frailty versus those without frailty [n = 10; mean difference (MD): 3.67; 95% CI: 2.26-5.08, I2 = 93%, P < 0.01]. Likewise, patients with frailty had significantly increased odds of HHF [n = 17; odds ratio (OR): 1.76; 95% CI: 1.50-2.07, I2 = 81%, P < 0.01]. Risk of bias assessment of the included studies was overall fair, while Egger's test showed publication bias regarding studies that examined LoS (P = 0.02).

CONCLUSIONS

Patients with frailty have longer LoS and more frequent HHF, underscoring the need for early, targeted interventions to manage frailty that may be attributed primarily to ageing and comorbidity-related status.

Home-Based Rehabilitation After Transcatheter Aortic Valve Replacement (REHAB-TAVR): A Pilot Randomized Controlled Trial

BACKGROUND

The benefit of early cardiac rehabilitation after transcatheter aortic valve replacement (TAVR) is not well established. This pilot study evaluated the feasibility and short-term effects of a home-based exercise program, with or without cognitive-behavioral intervention (CBI).

METHODS

We randomized 51 patients (mean age, 83.9 years; 19 women) to a home-based exercise program with CBI (Group A; n = 18) or without CBI (Group B; n = 15), or telephone-based education control (Group C; n = 18). The exercise program focusing on balance, flexibility, strength, and endurance began within 7 days post-discharge and was delivered once weekly by a physical therapist for 8 weeks. CBI included discussions on exercise benefits and barriers, goal setting, detailed exercise planning, and a weekly cash adherence incentive. The primary outcome was a disability score (range: 0-22; higher scores indicate greater disability) at 8 weeks. Secondary outcomes included the Short Physical Performance Battery (SPPB) (range: 0-12; higher scores indicate better function), self-efficacy, and outcome expectation scores. Feasibility outcomes included adherence and drop-out rates.

RESULTS

Fifteen participants (83.3%) in Group A, 10 (58.8%) in Group B, and 10 (52.6%) in Group C completed ≥ 5 of the eight assigned weekly sessions (p = 0.196). Two participants in each group were lost to follow-up. At 8 weeks, the home-based exercise groups (Group A and B combined) demonstrated lower disability scores (mean [SE]: 2.6 [0.3] vs. 4.5 [0.5]; p = 0.042) and higher SPPB scores (9.5 [0.6] vs. 6.5 [0.8]; p = 0.003) compared with the education group (Group C). Group A had lower disability scores than Group B (2.1 [0.4] vs. 3.4 [0.5]; p = 0.047), with no differences in self-efficacy and outcome expectation scores.

CONCLUSIONS

An early, home-based, multi-domain exercise program appears feasible and may prevent disability and improve physical function in older adults after TAVR. Adding CBI, including a modest cash incentive, showed trends toward improved adherence and reduced disability.

Novel Strategies to Promote Intensive Care Unit Recovery via Personalized Exercise, Nutrition, and Anabolic Interventions

Survivors of critical illness experience significant morbidity, reduced physiologic reserve, and long-term complications that negatively impact quality of life. Although rehabilitative treatments are beneficial during early recovery, there is limited evidence regarding effective multimodal rehabilitation, nutrition, and anabolic nutrient/agent strategies for improving long-term outcomes. This review discusses novel personalized rehabilitation, nutrition, and anabolic nutrient/agent (ie, creatine, β-hydroxy-β-methylbutyrate, testosterone) approaches that allow for precise exercise and nutrition prescription and have potential to improve patient care, address continued medical needs, and optimize long-term recovery. Continued research is needed to further evaluate effectiveness and implementation of these strategies throughout the continuum of care.

Improving effect of physical exercise on heart failure: Reducing oxidative stress-induced inflammation by restoring Ca2+ homeostasis

Heart failure (HF) is associated with the occurrence of mitochondrial dysfunction. ATP produced by mitochondria through the tricarboxylic acid cycle is the main source of energy for the heart. Excessive release of Ca2+ from myocardial sarcoplasmic reticulum (SR) in HF leads to excessive Ca2+ entering mitochondria, which leads to mitochondrial dysfunction and REDOX imbalance. Excessive accumulation of ROS leads to mitochondrial structure damage, which cannot produce and provide energy. In addition, the accumulation of a large number of ROS can activate NF-κB, leading to myocardial inflammation. Energy deficit in the myocardium has long been considered to be the main mechanism connecting mitochondrial dysfunction and systolic failure. However, exercise can improve the Ca2+ imbalance in HF and restore the Ca2+ disorder in mitochondria. Similarly, exercise activates mitochondrial dynamics to improve mitochondrial function and reshape intact mitochondrial structure, rebalance mitochondrial REDOX, reduce excessive release of ROS, and rescue cardiomyocyte energy failure in HF. In this review, we summarize recent evidence that exercise can improve Ca2+ homeostasis in the SR and activate mitochondrial dynamics, improve mitochondrial function, and reduce oxidative stress levels in HF patients, thereby reducing chronic inflammation in HF patients. The improvement of mitochondrial dynamics is beneficial for ameliorating metabolic flow bottlenecks, REDOX imbalance, ROS balance, impaired mitochondrial Ca2+ homeostasis, and inflammation. Interpretation of these findings will lead to new approaches to disease mechanisms and treatment.

Novel predictors of infection-related rehospitalization in older patients with heart failure in Japan

AIM

Rehospitalization of patients with heart failure (HF) incurs high health care costs and increased mortality. Infection-related rehospitalizations in patients with HF occur frequently, and the risk increases with age. This study aimed to identify the factors associated with infection-related rehospitalizations in older patients with HF.

METHODS

Demographic, clinical, and pharmacological data from 1061 patients with acute HF who were enrolled in the Kochi Registry of Subjects With Acute Decompensated Heart Failure (Kochi YOSACOI study) were analyzed. Additionally, a machine learning approach was applied in addition to the traditional statistical analysis model. Of the patients hospitalized for HF, 729 were ultimately analyzed.

RESULTS

During the 2-year postdischarge follow-up period, 121 (17%) patients were readmitted for infections. Logistic regression analysis identified a Japanese Cardiovascular Health Study (J-CHS) score of ≥3 (odds ratio, 1.83 [95% confidence interval, 1.18-2.83]; P = 0.007) at discharge as a key factor for infection-related rehospitalizations. Machine learning models confirmed that a higher J-CHS score and lower estimated glomerular filtration rate (eGFR) increased the risk of infection-related rehospitalizations. Decision tree analysis classified the risk into high (J-CHS score ≥3), medium (J-CHS score <3; eGFR ≤35.0) and low (J-CHS score <3; eGFR >35.0) groups.

CONCLUSIONS

Infection-related rehospitalizations occur in older patients with HF and are associated with frailty and eGFR. These findings provide valuable insights for health care providers to better manage the risk of infection-related rehospitalizations in older patients with HF, potentially improving patient outcomes.

Frailty integration in medical specialties: Current evidence and suggested strategies from the Clin-STAR frailty interest group

Frailty is a syndrome that can inform clinical treatments and interventions for older adults. Although implementation of frailty across medical subspecialties has the potential to improve care for the aging population, its uptake has been heterogenous. While frailty assessment is highly integrated into certain medical subspecialties, other subspecialties have only recently begun to consider frailty in the context of patient care. In order to advance the field of frailty-informed care, we aim to detail what is known about frailty within the subspecialties of internal medicine. In doing so, we highlight cross-disciplinary approaches that can enhance our understanding of frailty, focusing on ways to improve the implementation of frailty measures, as well as develop potential interventional strategies to mitigate frailty within these subspecialties. This has important implications for the clinical care of the aging population and can help guide future research.

Connecting the dots: A narrative review of the relationship between heart failure and cognitive impairment

Large clinical data underscore that heart failure is independently associated to an increased risk of negative cognitive outcome and dementia. Emerging evidence suggests that cerebral hypoperfusion, stemming from reduced cardiac output and vascular pathology, may contribute to the largely overlapping vascular dementia and Alzheimer's disease. Despite these insights, cognitive outcomes remain largely overlooked in heart failure management. This narrative review outlines the prevalence and risk of cognitive impairment in heart failure patients, exploring potential shared pathophysiological mechanisms and examining the impact of heart failure therapy on cognitive deficits. Additionally, it discusses clinical implications and suggests future treatment approaches targeting therapeutic outcomes. Cognitive impairment is prevalent among individuals with heart failure, with reported rates varying widely depending on assessment methods. Shared pathological pathways and risk factors, including atrial fibrillation (AF), hypertension, obesity and type 2 diabetes mellitus, suggest a causal link. Mechanisms such as poor perfusion, microembolic events, ischaemic syndromes and cerebral inflammation contribute to this relationship. Moreover, heart failure itself may exacerbate cognitive dysfunction. This emerging understanding posits that vascular dementia and Alzheimer's disease may represent a pathophysiological continuum, driven by both the accumulation of misfolded proteins and cerebrovascular pathology due to cardiovascular dysfunction. Understanding these links is crucial for developing effective treatment strategies. The complex interplay between heart failure and cognitive impairment underscores the necessity for a holistic patient care approach. Both conditions share analogous disease processes, influencing self-management and independence in patients. Prioritizing brain health in heart failure management is essential to enhance patient prognosis and general well-being.

A Randomized Controlled 'REAL-FITNESS' Trial to Evaluate Physical Activity in Patients With Newly Diagnosed Multiple Myeloma

BACKGROUND

Multiple myeloma (MM) is the second most common haematological malignancy. The predominantly older patients often suffer from comorbidities that impair their quality of life (QoL). Physical activity (PA) can be beneficial for cancer patients, but less evidence exists in MM. This randomized controlled trial (RCT) compared an exercise group with World Health Organization (WHO)-compliant PA (150 min aerobic exercise and 2 resistance training-sessions/week) vs. activity as usual (control group).

METHODS

Thirty-four newly diagnosed consecutive MM patients were randomized 1:1 to exercise vs. control groups. Guided training (2×/week) was performed for 3 months during bortezomib-cyclophosphamide-dexamethasone (VCd) induction. PA was monitored using smartwatches and diaries. Demographics, osteolytic lesions, infections, fatigue, depression, and biomarkers (albumin, creatine kinase, C-reactive protein, high-density lipoprotein, low-density lipoprotein and pro-brain natriuretic peptide) were compared in exercise vs. control cohorts. VCd-tolerance, response, 'timed-up-and-go-test' (TUGT), Revised Myeloma Comorbidity Index (R-MCI), QoL (SF-12 questionnaire), event-free survival and trainer assignment during the training period were assessed (13 tests at baseline, during VCd and end of treatment [EOT]).

RESULTS

The exercise group was more than twice as active as the control group, with an average aerobic activity of 162 versus 68 min/week, respectively. Trainer-guided muscle-strengthening exercises were performed 2×/week in the exercise group, in line with WHO recommendations. These data were monitored via smartwatches and training diaries. PA proved to be safe: No exercise-related SAEs or accidents occurred. The study adherence was 94% (32/34). In the exercise versus control group, AEs to VCd induction (6% vs. 25%), therapy intolerance (6% vs. 25%) and hospitalization (31% vs. 50%, respectively) occurred less frequently. VCd-dose adjustments in the exercise vs. control group were significantly less needed (6.3% vs. 37.5%, respectively). At EOT, patients in the exercise group showed less fatigue (6% vs. 75%), less depression (6% vs. 44%), better TUGT (6 vs. 11 s, respectively), improved R-MCI and QoL compared to the control group. Grip strength (right hand: 73-82 lb; left hand: 68-72 lb) significantly improved from baseline to EOT in the exercise group. Biomarkers did not significantly differ in both groups, but response to VCd-induction and event-free survival were improved in the exercise group, however, without reaching statistical significance.

CONCLUSIONS

PA in MM patients during induction is feasible and can improve fatigue, depression, TUGT, grip strength, comorbidities and QoL. More sport intervention offers are warranted to advance exercising in MM.

An Expert Opinion on the Management of Frailty in Heart Failure from the Australian Cardiovascular Alliance National Taskforce

Approximately 50% of all adults with heart failure (HF) are classified as frail. Frailty is a clinical state of 'accelerated ageing' that complicates management and results in adverse health outcomes. Despite recommendations for frailty assessment in HF guidelines, its implementation into routine clinical practice has been slow. Further, evidence to inform models of care and pharmacological treatment for individuals with HF who are classified as frail is lacking. The complexity of management underscores the importance of tailoring models of care that can improve the focus on frailty through multidisciplinary care teams. Frailty can be reduced in some cases through the comprehensive geriatric assessment model of care, integrating treatment pillars such as exercise, nutrition, social engagement and support networks, and optimised medication use. A national agenda for action on frailty in the context of HF is needed to advance policy, practice, education, and research improve health outcomes for individuals affected. In November 2023 the Australian Cardiovascular Alliance (ACvA) facilitated a national workshop on frailty and HF with key experts. This has led to the development of a frailty and HF national taskforce with the aim to address major priorities and unmet needs. This statement is first step for the taskforce in implementing a national agenda for the management of frailty in HF. Here we outline key considerations for policy, practice, education, and research in Australia.

The Implementation of Frailty Assessment Tools in the Acute Care Setting: A Scoping Review

BACKGROUND

Frailty is a syndrome of increased vulnerability to health stressors that is associated with adverse health outcomes. There is no universally accepted method of measuring frailty, and choosing among the many tools is often confusing for clinicians. Moreover, the acute care setting presents unique challenges to the operationalization of frailty measurement, and implementation into daily clinical practice has been variable. The objective of this scoping review was to map out and synthesize how frailty is being measured and used in the acute care setting.

METHODS

We used Arksey and O'Malley's methodological framework for scoping reviews. We searched MEDLINE, EMBASE, CINAHL, SCOPUS, and Google Scholar for primary studies assessing frailty in the acute care setting from inception to May 2023.

RESULTS

Our search resulted in 8834 articles, of which 2554 met inclusion criteria. Most articles (75%) were published in the last 5 years. The top three most frequently used methods of frailty measurement were the Frailty Index (41.0%), the Clinical Frailty Scale (23.3%), and the Fried Frailty Phenotype (9.3%). More than one frailty assessment tool was used in 11.2% of studies. While 99.6% of studies measured frailty assessment to evaluate the association of frailty with adverse outcomes or the validity of specific frailty tools, only 0.4% measured frailty to prospectively adapt healthcare provision.

CONCLUSION

There is an abundance of evidence demonstrating that frailty in acute care is associated with adverse health outcomes, with relatively scarce evidence on the effect of frailty assessment on prospectively adapting care. Future research focusing on the prospective management of frailty in acute care is needed.

Exercise-Induced Cardiac Lymphatic Remodeling Mitigates Inflammation in the Aging Heart

The lymphatic vasculature plays essential roles in fluid balance, immunity, and lipid transport. Chronic, low-grade inflammation in peripheral tissues develops when lymphatic structure or function is impaired, as observed during aging. While aging has been associated with a broad range of heart pathophysiology, its effect on cardiac lymphatic vasculature has not been characterized. Here, we analyzed cardiac lymphatics in aged 20-month-old mice versus young 2-month-old mice. Aged hearts showed reduced lymphatic vascular density, more dilated vessels, and increased inflammation and fibrosis in peri-lymphatic zones. As exercise has shown benefits in several different models of age-related heart disease, we further investigated the effects of aerobic training on cardiac lymphatics. Eight weeks of voluntary wheel running attenuated age-associated adverse remodeling of the cardiac lymphatics, including reversing their dilation, increasing lymph vessel density and branching, and reducing perilymphatic inflammation and fibrosis. Intravital lymphangiography demonstrated improved cardiac lymphatic flow after exercise training. Our findings illustrate that aging leads to cardiac lymphatic dysfunction, and that exercise can improve lymphatic health in aged animals.

Sedentary lifestyle and physical inactivity: A mutual interplay with early and overt frailty

AIMS

In recent years medical science and research are increasingly directed towards a holistic approach that considers health as global well-being rather than solely as the absence of disease. In this framework, lifestyle interventions and, in particular, physical exercise, are of crucial importance in prevention and treatment. Therefore, the purpose of this study is to describe this mutual interplay between physical behaviours, sarcopenia, and frailty, as well as to illustrate the role of structured exercise training in aging and disease.

DATA SYNTHESIS

Physical activity and exercise training are determinants of lifelong global wellness and healthy aging. On the contrary, sedentary behaviour and physical inactivity are strictly linked to frailty and pre-frailty, both in adults and the elderly, with or without chronic diseases. On the other hand, the presence of pathological conditions is associated with a more inactive and sedentary behaviour. The co-presence of these factors is characterized by a mutual causal exchange in which they are imbricated in a continuous mechanistic interplay that involves inflammation, sarcopenia, osteopenia, functional impairment and many other pathophysiological aspects that rapidly can lead to a status of frailty.

CONCLUSION

A sedentary lifestyle and physical inactivity critically affect alterations in body composition and loss in functional capacity, typically linked to aging and accelerated by chronic diseases. However, physical activity and exercise can counteract the onset of pre-frailty and frailty by conferring beneficial effects on the individual's overall well-being.

State of the Art in Measuring Frailty in Patients With Heart Failure: from Diagnosis to Advanced Heart Failure

PURPOSE OF REVIEW

This review aims to present the current state of the art in measuring frailty in patients with heart failure (HF), covering the entire spectrum from diagnosis to advanced stages of the disease. Frailty is a critical factor that significantly impacts outcomes in heart failure, and accurate assessment is essential for guiding treatment and improving prognosis.

RECENT FINDINGS

Frailty is increasingly recognized as a key determinant of morbidity and mortality in HF patients. Various tools are available for assessing frailty, but there is no consensus on the optimal method. The assessment of frailty needs to be multidimensional, incorporating physical, cognitive, and social domains. Early detection of frailty, coupled with personalized interventions, has the potential to improve patient outcomes. Integrating routine frailty assessments into the clinical care of heart failure patients is essential for optimizing treatment. Future research should focus on standardizing frailty assessment tools and integrating innovative technologies, such as artificial intelligence, to enhance the precision and applicability of these assessments in clinical practice.

Novel therapeutic insights into pathological cardiac hypertrophy: tRF-16-R29P4PE regulates PACE4 and metabolic pathways

Pathological cardiac hypertrophy (PCH) is a complex condition with an incompletely understood pathogenesis. Emerging evidence suggests that transfer RNA-derived small RNAs (tsRNAs) may play a significant role in various cellular processes, yet their impact on PCH remains unexplored. In this study, we performed tsRNA sequencing on plasma samples from PCH patients and identified a marked decrease in the expression of tRNA-related fragment 16-R29P4PE (tRF-16-R29P4PE), a specific tsRNA fragment, with a diagnostic area under the curve value of 0.7750. Using Angiotensin II (Ang II)-stimulated H9c2 cardiomyocytes as an in vitro model and Sprague-Dawley rats as an in vivo model, we investigated the effects of tRF-16-R29P4PE minic/inhibitors and silencing of the paired basic amino acid cleaving system 4 (PACE4) gene. Our results demonstrated that modulating tRF-16-R29P4PE expression significantly reduced brain natriuretic peptide (BNP) and free fatty acid levels while enhancing ATP production, glucose levels, and mitochondrial membrane potential. These effects were accompanied by the downregulation of PACE4, hypoxia-inducible factor-1α (HIF-1α), glucose transporter-4 (GLUT-4), and medium-chain acyl-CoA dehydrogenase (MCAD), as well as the upregulation of peroxisome proliferator-activated receptor α (PPARα). Animal experiments revealed that tRF-16-R29P4PE minic improved cardiac function, reduced myocardial fibrosis, and mitigated metabolic disorders and mitochondrial damage. Furthermore, co-immunoprecipitation (Co-IP) and molecular docking assays confirmed a direct interaction between PACE4 and HIF-1α, and luciferase reporter assays identified PACE4 as a direct target of tRF-16-R29P4PE. By regulating the PACE4 and HIF-1α/PPARα signaling pathways, tRF-16-R29P4PE alleviates PCH, providing a promising molecular target for therapeutic intervention.

Cardiac Rehabilitation and Heart Failure with Reduced Ejection Fraction: Pathophysiology, Benefits, and Precautions

Heart failure (HF) is a highly comorbid condition associated with significant mortality, despite advances in current medical management. Patients who suffer from HF represent a high needs disease care population in whom structured, long-term chronic disease care delivery models, such as cardiac rehabilitation (CR), have been shown to be highly cost effective in reducing hospitalizations and improving quality of life. HF with reduced ejection fraction affects a growing number of Canadians and health care costs secondary to this condition are increasing, with further increases over the next decade to be expected. CR is a guideline-directed medical therapy for patients living with HF with reduced ejection fraction, and with increasing numbers of HF patients across the world, there is a prescient need to revisit the benefits, safety, and the prescription of this intervention for the health care professionals who treat this condition. Certainly, there is a clinical need for HF practitioners to better understand the pathophysiological benefits of CR with respect to exercise training, as well as the prudent precautions required to facilitate the safe delivery of this highly cost-effective patient intervention.

Underpinnings of Heart Failure With Preserved Ejection Fraction in Women - From Prevention to Improving Function. A Co-publication With the American Journal of Preventive Cardiology and the Journal of Cardiac Failure

Heart failure with preserved ejection fraction (HFpEF) represents a major clinical challenge with rising global prevalence. Women have a nearly double lifetime risk of developing HFpEF compared to heart failure with reduced ejection fraction (HFrEF). In HFpEF, sex differences emerge both in how traditional cardiovascular risk factors (such as hypertension, obesity, and diabetes) affect cardiac function and through distinct pathophysiological mechanisms triggered by sex-specific events like menopause and adverse pregnancy outcomes. These patterns influence not only disease development, but also therapeutic responses, necessitating sex-specific approaches to treatment. This review aims to synthesize existing knowledge regarding HFpEF in women including traditional and sex-specific risk factors, pathophysiology, presentation, and therapies, while outlining important knowledge gaps that warrant further investigation. The impact of HFpEF spans a woman's entire lifespan, requiring prevention and management strategies tailored to different life stages. While understanding of sex-based differences in HFpEF has improved, significant knowledge gaps persist. Through examination of current evidence and challenges, this review highlights promising opportunities for innovative research, therapeutic development, and clinical care approaches that could transform the management of HFpEF in women.

Temporal Trends in Mortality and Hospitalization Risk in Patients With Heart Failure According to the Hospital Frailty Risk Score

BACKGROUND

Heart failure (HF) and frailty often coexist. However, it is unknown how the interplay between HF and frailty at HF onset impacts prognosis of frail patients with HF and how this has evolved over time.

METHODS AND RESULTS

We identified 131 235 patients with new-onset HF (median age 74 years, 39.7% women) from Danish nationwide registers in 1999 to 2017. Stratification according to the Hospital Frailty Risk Score resulted in (1) 102 635 (78%) nonfrail, (2) 26 054 (20%) moderately frail, and (3) 2609 (2%) severely frail patients. The proportion of moderately frail patients increased from 13.2% to 24.9%. Five-year absolute risks of all-cause mortality, HF hospitalization, and non-HF hospitalization were calculated using the Kaplan-Meier and Aalen-Johansen estimators. From 1999 to 2002 to 2003 to 2017, all-cause mortality risk (95% CI) declined from 56.4% (55.8%-57.0%) to 33.3% (32.6%-34.1%), 79.8% (78.5%-81.0%) to 58.6% (57.2%-60.1%), and 90.8% (85.6%-96.0%) to 79.8% (76.4%-83.2%) in nonfrail, moderately frail, and severely frail patients, respectively. HF hospitalization risk remained almost constant over the study period. Non-HF hospitalization risk declined from 74.0% (73.5%-74.5%) to 65.8% (65.0%-66.5%) in nonfrail patients and remained stable overall in moderately frail and severely frail patients over the study period.

CONCLUSIONS

We observed an increase in frail patients. Mortality decreased for all frailty groups but remained high for severely frail patients. These findings indicate the need for further evidence on the optimization of care for frail patients with HF, and future research should address the development of comprehensive management strategies, integrating frailty assessment into standard clinical care and focused care for older patients with HF.

Trajectory of health-related quality of life during and after hospitalisation due to worsening of heart failure

PURPOSE

This study aimed to examine the trajectory in health-related quality of life (HRQoL) during and after hospitalisation for worsening of heart failure (HF) in Malaysia.

METHODS

200 patients with heart failure and reduced ejection fraction (HFrEF) admitted into two hospitals in Malaysia due to worsening of HF were surveyed using the EQ-5D-5 L questionnaire. The primary outcomes were utility values at admission, discharge and 1-month post-discharge (1MPD). Secondary outcomes included the visual analogue scores (VAS) and the proportion of patients reporting each EQ-5D-5 L dimension levels. Missing data were imputed using multiple imputation, and generalised linear mixed models were fitted.

RESULTS

At admission, the unadjusted mean utility values and VAS scores for HFrEF patients in Malaysia were as low as 0.150 ± 0.393 and 38.2 ± 20.8, respectively. After a median hospital stay of 4 days, there was a significant improvement in utility values and VAS scores by 0.510 (95% CI: 0.455-0.564) and 28.8 (95% CI: 25.5-32.1), respectively. The utility value and VAS score at 1-month post-discharge were not significantly different from discharge. The proportion of HFrEF patients reporting problems and severe problems in mobility, self-care, usual activities, and anxiety/depression, pain/discomfort reduced at varying degree from admission to discharge and 1MPD.

CONCLUSION

HF is a progressive condition with substantial variation in HRQoL during the disease trajectory. During hospitalisation due to worsening of HF, HFrEF population has unfavourable HRQoL. Rapid and significant HRQoL improvement was observed at discharge, which sustained over one month. The study findings can inform future cost-effectiveness analyses and policies.

Beyond Guideline-Directed Medical Therapy: Nonpharmacologic Management for Patients With Heart Failure

Heart failure (HF) is a leading cause of cardiovascular morbidity, mortality, and health care expenditure. Guideline-directed medical therapy and device-based therapy in HF are well established. However, the role of nonpharmacologic modalities to improve HF care remains underappreciated, is underused, and requires multimodal approaches to care. Diet, exercise and cardiac rehabilitation, sleep-disordered breathing, mood disorders, and substance use disorders are potential targets to reduce morbidity and improve function of patients with HF. Addressing these factors may improve symptoms and quality of life, reduce hospitalizations, and improve mortality in heart failure. This state-of-the-art review discusses dietary interventions, exercise programs, and the management of sleep-disordered breathing, mood disorders, and substance use in individuals with heart failure. The authors review the latest data and provide optimal lifestyle recommendations and recommended prescriptions for nonpharmacologic therapies.

Impact of in-hospital cardiac rehabilitation on hospital-associated disability after transcatheter aortic valve implantation

BACKGROUND

Hospital-associated disability (HAD), a decline in the ability to perform activities of daily living (ADL) during hospitalization, is a modifiable target in integrated care for older adults. The aim of this study was to determine the impact of inpatient cardiac rehabilitation (CR) on the development of HAD in older patients with aortic stenosis undergoing transcatheter aortic valve implantation (TAVI).

METHODS

Older patients undergoing TAVI were extracted from the Japanese nationwide database (JROAD-DPC) from April 2014 to March 2021 and were divided into patients receiving inpatient CR (CR group) and a non-CR group. HAD was defined as a decrease in the Barthel Index (BI) score ≥5 points at discharge compared with the score at admission.

RESULTS

Of 19,789 eligible patients, 17,066 (86%) underwent inpatient CR. The overall prevalence of HAD was 9.6%, with a lower incidence in the CR group than in the non-CR group (8.8% vs. 14.2%, p < 0.001). Random forest analysis revealed key features associated with HAD risk including BI score at admission, inpatient CR participation, age, body mass index (BMI), and chronic kidney disease. The results of multivariate logistic regression analysis showed that participation in inpatient CR was associated with a lower odds ratio (OR) of HAD (OR, 0.62; 95% confidence interval, 0.54-0.70), with similar results in inverse probability of treatment weighting-adjusted logistic regression analyses (OR, 0.82; 95% confidence interval, 0.77-0.88). Analyses in subgroups of interest showed heterogeneity in the effects of inpatient CR with possible loss in patients with a BMI of <18.5 kg/m2 or a BI score of less than 60 points at admission.

CONCLUSIONS

The data suggest a beneficial effect of inpatient CR participation on the prevention of HAD in older patients undergoing TAVI, but the effect may be limited in lean patients with disability for ADL before TAVI.

Age-Specific Changes in Physical Function in Patients with Acute Decompensated Heart Failure

Cardiac rehabilitation (CR) improves physical function in patients with acute decompensated heart failure (ADHF) and frailty. However, few studies have assessed physical function through multiple measures during hospitalization; moreover, the effect of age remains unclear. This study aimed to evaluate age-specific changes in physical function during the acute-phase treatment period in patients with ADHF. Patients with ADHF hospitalized between June 2018 and June 2023, who were aged ≥ 60 years and underwent CR, were included in the study. Physical function assessments at admission and discharge included grip strength, quadriceps isometric strength, short physical performance battery (SPPB), gait speed, and frailty. Changes in physical function from admission to discharge were assessed. The mean age of the 531 patients was 79.8 ± 9.0 years and 58% were male. Physical function at admission and discharge significantly decreased with age according to all measures. In patients aged ≥ 90 years, quadriceps isometric strength (0.27 ± 0.11 kgf/BW kg) and the SPPB score (4.5 ± 3.6 points) were severely impaired at admission. However, no significant differences were observed in changes in physical function according to age; the improvement in the SPPB score tended to increase with age (+1.7 ± 1.9, +2.3 ± 2.1, +2.2 ± 2.4, and +2.3 ± 1.8, in the 60-69-, 70-79-, 80-89-, and ≥ 90-year age groups, respectively). The improvement in frailty was similar in all groups. Although physical function declined with age, the changes in physical function were similar in patients with ADHF at any age above 60 years who underwent CR.

Effects of Acute Phase Intensive Exercise Training in Patients With Acute Decompensated Heart Failure

BACKGROUND

Acute decompensated heart failure (ADHF) leads to hospitalizations and functional decline in older adults. Although cardiac rehabilitation (CR) is effective for stable heart failure, its impact on ADHF patients, particularly those without frailty, is unclear.

OBJECTIVES

The goal of this study was to evaluate the efficacy and safety of early in-hospital CR for patients hospitalized with ADHF who are not frail.

METHODS

In this multicenter trial (ACTIVE-ADHF [Effects of Acute Phase Intensive Exercise Training in Patients with Acute Decompensated Heart Failure]), ADHF patients without physical frailty were randomized 2:1 to undergo either exercise-based CR or standard care. The intervention included early mobilization and structured exercise training. The primary outcome was the change in 6-minute walk distance (6MWD) from baseline to discharge. Secondary outcomes assessed physical and cognitive function, quality of life, and safety.

RESULTS

A total of 91 patients were randomized to treatment, with 59 allocated to the intervention group and 32 to the control group. The primary outcome, 6MWD, improved significantly more in the intervention group, with a mean increase of 75.0 ± 7.8 m vs 44.1 ± 10.2 m in the control group, with an effect size of 30.9 ± 13.1 m (95% CI: 4.8-57.0; P = 0.021). The intervention group showed favorable results in secondary efficacy outcomes, including physical and cognitive function, physical activity, and quality of life. Safety outcomes were similar between groups, except for a greater reduction in B-type natriuretic peptide levels at 90 days' postdischarge in the intervention group.

CONCLUSIONS

In patients with ADHF without physical frailty, in-hospital exercise-based CR led to significant improvements in 6MWD at 2 weeks after randomization without compromising safety.

Acupuncture and Kinesitherapy Improve Physical Activity More than Kinesitherapy Alone in Patients with Acute Decompensated Chronic Heart Failure with Reduced Ejection Fraction Who Are Already on Optimal Drug Therapy: A Randomized, Sham-Controlled, Double-Blind Clinical Study

Background/Objectives: It is unknown how early exercise therapy combined with acupuncture (AP) affects the speed of recovery in patients suffering from heart failure with reduced ejection fraction (HFrEF) who are hospitalized due to worsening HF. Methods: A prospective, sham-procedure-controlled, double-blind, randomized clinical trial with three patient groups was conducted. The study included patients with HFrEF who were hospitalized for worsening HF. After initial stabilization, patients were randomly assigned to three groups, the controls (C) treated with optimal drug therapy (ODT); E1 received ODT with kinesitherapy, and sham AP; E2 received ODT, kinesitherapy, and needle AP aiming to enhance compensation. Improvement in physical activity was measured by the modified Barthel index (A test), 2 or 6 min walking tests, an endurance walking test, and decrease of blood brain natriuretic peptide (BNP). Results: A total of 120 patients completed the study. The average age was 74 years, 73.3% were male, median EF was 32%, and 83.3% were New York Heart Association (NYHA) Class III. After the fifth day of therapy, the E2 group showed the greatest improvement in the A test compared to other groups (p = 0.022). After 5 days, 80%, 50%, and 10% achieved an A test score of 30 or higher, demonstrating functional independence, (p < 0.01) in the E2, E1, and C groups, respectively. At hospital discharge, the E2 group showed significantly better walking endurance compared to the E1 and C groups (p < 0.001). At discharge, BNP decreased significantly more in both E groups, compared to the C group. Conclusions: Short-term early rehabilitation with AP and kinesitherapy significantly improves the functional status of HFrEF decompensated patients when compared to kinesitherapy alone and ODT.

Comparison of diaphragmatic breathing exercises and incentive spirometry on the functional status of heart failure patients: a randomized controlled trial

BACKGROUND

Respiratory muscle weakness in heart failure (HF) can deteriorate its symptoms such as fatigue, dyspnea, and impaired functional status. Pulmonary rehabilitation can strengthen these muscles. This study aimed to determine the impact of breathing exercises on fatigue severity, dyspnea, and functional classification in HF patients.

METHODS

A three-arm single-blind randomized controlled trial was conducted on 90 hospitalized HF patients in three 30-participant groups including diaphragmatic breathing group (DG), incentive spirometry group (SG), and control group (CG). The interventions were performed thrice daily for 10 days in DG and SG. The Fatigue Severity Scale (FSS), Borg dyspnea scale, and New York Heart Association (NYHA) functional classification were used before and after the intervention. Data were analyzed using SPSS-20 software.

RESULTS

After the intervention, the patients' frequency with severe fatigue decreased by 30% in both DG and SG (p < 0.001); the mean dyspnea score in DG and SG respectively reduced by 0.7 and 0.9 units at rest (p < 0.001) and reduced by 2.93 and 2.73 units during activity (p < 0.001); the total patients' frequency in functional class III and IV was significantly decreased by 30% in DG and 33.3% in SG (p < 0.001). The intervention groups were not significantly different regarding fatigue severity, dyspnea, and functional classification. While in CG these outcomes had no significant reduction after the intervention.

CONCLUSION

In this study breathing exercises could reduce fatigue and dyspnea, and improve NYHA functional classification of HF patients which can be included in nursing care plans for respiratory rehabilitation in HF.

Multicomponent telerehabilitation program for veterans with multimorbidity: A randomized controlled feasibility study

BACKGROUND

Older veterans with multimorbidity experience physical and social vulnerabilities that complicate receipt of and adherence to physical rehabilitation services. Thus, traditional physical rehabilitation programs are insufficient to address this population's heterogenous clinical presentation.

OBJECTIVE

To evaluate the feasibility and acceptability of a MultiComponent TeleRehabilitation (MCTR) program for older veterans with multimorbidity.

DESIGN

Randomized controlled cross-over feasibility study.

SETTING

Telehealth from Veterans Affairs Medical Center to participants' homes.

PARTICIPANTS

Fifty U.S. military veterans, age ≥60 years (mean ± SD; 69.2 ± 6.7) with ≥3 comorbidities (6.0 ± 1.9), and impaired physical function were randomized and allocated equally to two groups.

INTERVENTION

The MCTR program consisted of high-intensity rehabilitation, coaching, social support, and technologies. Physical therapists delivered 12 individual and 20 group telerehabilitation sessions/participant. Participants in the education group started the MCTR program after 12 weeks.

MAIN OUTCOME MEASURES

The primary outcome was combined adherence (>75% of participants attending ≥80% sessions). Acceptability was measured by the Acceptability of Intervention Measure. Secondary outcomes included safety, participant surveys, and physical function. Patient-level outcomes were collected at baseline, 12 (primary time point), and 24 weeks.

RESULTS

Of 50 participants, 39 adhered to total session attendance (0.78 [95% confidence interval: 0.64-0.88], p = .76), 45 adhered to individual sessions (0.90 [95% confidence interval: 0.78-0.97], p = .01), and 48 rated the program as acceptable (0.96 [95% confidence interval: 0.85-0.99], p < .001). Thirty-five participants reported 78 safety events, and 12 (15%) had some degree of relatedness to the protocol. Most patient-level outcomes were similar between groups at 12-weeks.

CONCLUSIONS

The MCTR program was feasible based on high adherence to individual sessions and high acceptability. Adherence results were consistent with previous exercise studies in older adults. Most in-session safety events were related to underlying medical conditions and consistent with in-person physical rehabilitation safety events. These results can inform use of telerehabilitation for similar populations.

Combined endurance and resistance exercise training in heart failure with preserved ejection fraction: a randomized controlled trial

Endurance exercise training (ET) is an effective treatment in heart failure with preserved ejection fraction (HFpEF), but the efficacy of resistance training in this patient population has been only scarcely evaluated. In this multicenter, randomized trial, we evaluated the effects of combined endurance and resistance training over 12 months in patients with HFpEF. The primary endpoint was a modified Packer score, including all-cause mortality, hospitalizations classified as potentially related to heart failure or exercise and changes in peak oxygen consumption (V ̇ O 2 ), diastolic function (E/e'), New York Heart Association (NYHA) class and global self-assessment (GSA). In total, 322 patients (mean age, 70 years; 192 females (59.6%) and 130 males (40.4%)) were randomized (1:1) to ET or usual care (UC). At 12 months, the modified Packer score showed an improvement in 33 ET patients (20.5%) and in 13 UC patients (8.1%) and showed a worsening in 69 ET patients (42.9%) and in 71 UC patients (44.1%) (Kendall's tau-b = -0.073, P = 0.17). Although the primary endpoint was not met, clinically relevant differences favoring the ET group as compared to the UC group were observed for the following secondary endpoints: changes in peakV ̇ O 2 (mean difference, 1.3 ml kg-1 min-1 (95% confidence interval (CI): 0.4-2.1)) and NYHA class (odds ratio = 7.77 (95% CI: 3.73-16.21)). No significant between-group differences were observed for other secondary endpoints, including change in E/e', change in GSA, time to cardiovascular hospitalization or all-cause mortality. In conclusion, 1 year of combined endurance and resistance ET did not result in a significantly better modified Packer score, but it did result in improvements in important clinical parameters, such as peakV ̇ O 2 and NYHA class, as compared to UC.

Real-World Data on Patients With Acquired Haemophilia A in Japan Undergoing Rehabilitation or With Low Activities of Daily Living Scores: The ORIHIME II Study

INTRODUCTION

Acquired haemophilia A (AHA) is characterized by the development of autoantibodies against factor VIII, reducing its activity and potentially resulting in bleeding.

AIM

To assess the characteristics of people with AHA undergoing rehabilitation and/or with low activities of daily living (ADL) scores, thereby characterizing unmet needs in the management of AHA and informing treatment optimization.

METHODS

ORIHIME II, the largest epidemiological and treatment survey of AHA in Japan, is a descriptive, retrospective, observational study conducted using health claims data from April 2008 to October 2021. The primary outcome measures were rehabilitation practice and ADL scores on hospital admission and discharge; use of haemostatic agents and immunosuppressive therapy were also assessed.

RESULTS

Overall, 427 patients in Japan were eligible for the study. Median (Q1-Q3) age was 78.0 (70.0-84.0) years; 264 patients (61.8%) were male. Median (Q1-Q3) time to start rehabilitation was 9 (4-21) and 14 (6-31) days for those with an admission ADL score of <85 and ≥85, respectively. Of the 427 patients, 249 underwent rehabilitation. The most common rehabilitation type was for disuse syndrome; haemostatic agents were more commonly used in patients undergoing earlier rehabilitation.

CONCLUSION

The physical condition of the patient at hospitalization was associated with rehabilitation practice and the ability of the patient to perform day-to-day activities independently. Treatment strategies should be optimized to allow initiation of rehabilitation as early as possible in the course of AHA.

Global consensus on optimal exercise recommendations for enhancing healthy longevity in older adults (ICFSR)

Aging, a universal and inevitable process, is characterized by a progressive accumulation of physiological alterations and functional decline over time, leading to increased vulnerability to diseases and ultimately mortality as age advances. Lifestyle factors, notably physical activity (PA) and exercise, significantly modulate aging phenotypes. Physical activity and exercise can prevent or ameliorate lifestyle-related diseases, extend health span, enhance physical function, and reduce the burden of non-communicable chronic diseases including cardiometabolic disease, cancer, musculoskeletal and neurological conditions, and chronic respiratory diseases as well as premature mortality. Physical activity influences the cellular and molecular drivers of biological aging, slowing aging rates-a foundational aspect of geroscience. Thus, PA serves both as preventive medicine and therapeutic agent in pathological states. Sub-optimal PA levels correlate with increased disease prevalence in aging populations. Structured exercise prescriptions should therefore be customized and monitored like any other medical treatment, considering the dose-response relationships and specific adaptations necessary for intended outcomes. Current guidelines recommend a multifaceted exercise regimen that includes aerobic, resistance, balance, and flexibility training through structured and incidental (integrated lifestyle) activities. Tailored exercise programs have proven effective in helping older adults maintain their functional capacities, extending their health span, and enhancing their quality of life. Particularly important are anabolic exercises, such as Progressive resistance training (PRT), which are indispensable for maintaining or improving functional capacity in older adults, particularly those with frailty, sarcopenia or osteoporosis, or those hospitalized or in residential aged care. Multicomponent exercise interventions that include cognitive tasks significantly enhance the hallmarks of frailty (low body mass, strength, mobility, PA level, and energy) and cognitive function, thus preventing falls and optimizing functional capacity during aging. Importantly, PA/exercise displays dose-response characteristics and varies between individuals, necessitating personalized modalities tailored to specific medical conditions. Precision in exercise prescriptions remains a significant area of further research, given the global impact of aging and broad effects of PA. Economic analyses underscore the cost benefits of exercise programs, justifying broader integration into health care for older adults. However, despite these benefits, exercise is far from fully integrated into medical practice for older people. Many healthcare professionals, including geriatricians, need more training to incorporate exercise directly into patient care, whether in settings including hospitals, outpatient clinics, or residential care. Education about the use of exercise as isolated or adjunctive treatment for geriatric syndromes and chronic diseases would do much to ease the problems of polypharmacy and widespread prescription of potentially inappropriate medications. This intersection of prescriptive practices and PA/exercise offers a promising approach to enhance the well-being of older adults. An integrated strategy that combines exercise prescriptions with pharmacotherapy would optimize the vitality and functional independence of older people whilst minimizing adverse drug reactions. This consensus provides the rationale for the integration of PA into health promotion, disease prevention, and management strategies for older adults. Guidelines are included for specific modalities and dosages of exercise with proven efficacy in randomized controlled trials. Descriptions of the beneficial physiological changes, attenuation of aging phenotypes, and role of exercise in chronic disease and disability management in older adults are provided. The use of exercise in cardiometabolic disease, cancer, musculoskeletal conditions, frailty, sarcopenia, and neuropsychological health is emphasized. Recommendations to bridge existing knowledge and implementation gaps and fully integrate PA into the mainstream of geriatric care are provided. Particular attention is paid to the need for personalized medicine as it applies to exercise and geroscience, given the inter-individual variability in adaptation to exercise demonstrated in older adult cohorts. Overall, this consensus provides a foundation for applying and extending the current knowledge base of exercise as medicine for an aging population to optimize health span and quality of life.

Cardiac rehabilitation for old-old patients with heart failure and severe functional impairment

BACKGROUND

The effects of cardiac rehabilitation (CR) in old patients with heart failure (HF) and severe functional impairment (SFI) are not well established.

METHODS

We studied 1397 patients with HF and severe functional impairment, defined as a six-minute walking distance (6MWD) <300 m, admitted to inpatient CR. The patients were divided into three groups: Group A (young, ≤65 years), Group B (old-young, 66 to 75 years), and Group C (old-old, >75 years). The primary outcome was an increase in 6MWD to 300 m or more after CR. We used multivariable Cox modeling to determine the association of the primary outcome with three-year mortality after discharge from CR.

RESULTS

At admission to CR, 38.5 % of the patients in group A, 40.0 % in group B, and 46.3 % in group C (p = .029) were unable to walk unassisted. Of these patients, 29.5 %, 32.6 %, and 30.2 % (p = .835), respectively, regained the ability to walk independently. Overall, 370 (26.5 %) patients achieved the primary outcome, 49.1 % in group A, 32.2 % in group B, and 15.7 % in group C (p < .001). The adjusted HR of 3-year mortality for the patients who achieved the primary outcome was 0.53 (95 %CI 0.34-0.83; p = .005) in group A, 0.49 (95 %CI 0.33-0.74; p = .001) in group B, and 0.68 (95 %CI 0.47-0.98; p = .037) in group C.

CONCLUSIONS

Our findings suggest that old-old patients with HF and severe functional impairment may benefit from CR and that functional improvement may predict improved survival.

Effects of exercise based cardiac rehabilitation delivery modes on chronic heart failure: a systematic review and network meta-analysis

Chronic heart failure (CHF) represents one of the most severe and advanced stages of cardiovascular disease. Despite the critical importance of cardiac rehabilitation (CR) in CHF management, while studies have explored the effectiveness of various CR delivery modes and offered valuable context-specific insights, their relative efficacy remains inconsistent across different patient groups, healthcare environments, and intervention approaches. A clearer understanding requires comprehensive comparisons and in-depth analyses to address these variations. Systematic searches were conducted in databases including Pubmed, Embase, Cochrane Central Register of Controlled Trials, and Web of Science, up to August 2024. Two researchers independently screened the literature according to strict inclusion criteria, extracted relevant data, and assessed the quality of included studies using Cochrane Collaboration tools and the Jadad scale. Subsequent pairwise and network meta-analyses were performed using statistical software, including Stata 17.0, to present the results graphically. The network meta-analysis included 9,552 articles, with 33 meeting the inclusion criteria and examining eleven different interventions. All interventions outperformed routine care. Combined CR with aerobic exercise and resistance training (HCR [AE + RE]) significantly improved Minnesota Living with Heart Failure Questionnaire (MLHFQ) scores and 6-min walk test (6MWT) performance, and reduced rehospitalization rates [SUCRA = 96%]. Center-based cardiac rehabilitation (CBCR) with high-intensity interval training (HIIT) was the most effective in enhancing left ventricular ejection fraction (LVEF), while CBCR(AE) demonstrated the greatest improvement in peak oxygen uptake (Peak VO2) [RR = 3.64, 95% CI: 1.66-7.95]. Our analysis identifies HCR (AE + RE) as the most effective intervention for improving quality of life (MLHFQ), exercise capacity (6MWT), and reducing hospital readmissions. CBCR (HIIT) was optimal for enhancing cardiac function through improved LVEF, while CBCR (AE) effectively boosted peak VO2.PROSPERO: CRD42024517039, Review Completed not published.

Associations of cognitive decline with outcomes of cardiovascular rehabilitation in patients with cardiovascular disease

BACKGROUND

Patients with cardiovascular disease (CVD) are often contending with various comorbidities including cognitive decline. Cognitive decline is a risk marker for adverse outcomes in these patients. On the other hand, cardiovascular rehabilitation (CVR) improves clinical outcomes. However, it remains uncertain whether CVR is associated with favorable outcomes in patients with CVD and cognitive decline. Therefore, the present study aimed to investigate whether CVR is associated with favorable outcomes in patients with CVD and cognitive decline.

METHODS

We reviewed 4232 patients admitted for CVD. Cognitive function was assessed using the Mini-Cog at hospital discharge, and a score of <3 was defined as cognitive decline. We measured the 6-min walking distance (6MWD) at discharge and 5 months after CVR prescription for participants in outpatient CVR. The primary outcome was change in exercise tolerance (Δ6MWD), and the secondary outcome was composite events (all-cause death and/or re-admission due to CVD). We compared Δ6MWD between patients with and without cognitive decline and examined the association between outpatient CVR participation and composite events.

RESULTS

Of all patients, 768 had cognitive decline. There was no significant difference in Δ6MWD between the cognitive decline and non-cognitive decline groups, even after adjusting for confounders [estimated mean difference: 2.20 m; 95 % confidence interval (CI): -0.60-5.00 m]. Additionally, participation in outpatient CVR was associated with lower rate of composite events, regardless of cognitive decline [adjusted hazard ratio (aHR): 0.589; 95 % CI: 0.552-0.627 in the cognitive decline group and aHR: 0.767; 95 % CI: 0.742-0.793 in the non-cognitive decline group]. An interaction was observed based on the presence of cognitive decline (p = 0.011).

CONCLUSION

Regardless of cognitive decline, participation in outpatient CVR was associated with increased exercise tolerance. Furthermore, outpatient CVR was linked to reduced composite events in both, with particularly potent association in cognitively impaired patients.

Association Between Amount of Physical Activity and Clinical Outcomes After Treatment for Cardiovascular Disease in Cancer Survivors

Background

The present study aimed to investigate the association between physical activity before the incidence of cardiovascular disease (CVD) and clinical outcomes in cancer survivors.

Methods and Results

We analyzed 904 cancer survivors (median age [interquartile range] 75 [68-80] years; 297 [32.9%] patients were female) who required hospitalization for treatment of CVD. The amount of physical activity 1 month before the admission was assessed using the 3-question (3Q) assessment tool, and categorized as minimal, low, adequate, and high according to physical activity level. The primary outcome was the composite events of all-cause death and/or rehospitalization for CVD up to 1 year after discharge. The total amount of physical activity was identified in 544 (60.2%) patients in the minimal group, 95 (10.5%) in the low group, 253 (28.0%) in the adequate group, and 12 (1.3%) in the high group. A total of 686 (75.9%) patients completed follow up, with 252 (27.9%) composite events occurring. Even after adjustment for various confounders, higher physical activity was significantly associated with a lower composite event rate (adjusted hazard ratio [95% confidence interval] 0.859 [0.833-0.900]).

Conclusions

High physical activity in cancer survivors was associated with a lower composite event rate after treatment for CVD. Assessment of prehospital physical activity using the 3Q score may be useful in their risk stratification.

Feasibility of a Multidomain Resiliency Assessment in Patients With Advanced Heart Failure Requiring Surgery: A Pilot Study

OBJECTIVE

The resiliency of patients who have advanced heart failure (HF) and undergo a physical stressor such as heart transplantation or left ventricular assist device implantation has yet to be studied in the physical, cognitive, and psychosocial domains. The primary aim of this pilot study was to assess the feasibility of a multidomain resiliency assessment in patients who have advanced HF and require surgery.

METHODS

A battery of assessments in each of the domains was completed at baseline before surgical intervention, after intensive care discharge, and 3 and 6 months after surgery. Feasibility was assessed through completion rates, time required to complete the assessments, and qualitative feedback from assessors.

RESULTS

Although various completion rates were noted at different time points, high completion rates were seen for grip strength, the modified Fried frailty phenotype, and the Montreal Cognitive Assessment. Additionally, when controlled for patients who were medically restricted from physical function, the Short Physical Performance Battery, gait speed, and the 30-second chair stand test also had high completion rates. A trend toward return to baseline status or an improvement in baseline status was observed in all physical and cognitive assessments and most psychosocial assessments at 3 and 6 months. Minimal change was noted in the Brief Resilience Scale questionnaire.

CONCLUSION

This pilot study demonstrates that a multidomain assessment of resiliency is feasible in patients with advanced HF. Future studies are needed to help determine specific assessments or patient factors that would help predict positive postsurgical outcomes in this population.

IMPACT

This study has implications for clinical practice on the most feasible assessments in multiple domains for patients who have advanced HF and are being evaluated for heart transplantation or left ventricular assist device.

Assessing Frailty-Specific Treatment Effect in Cardiovascular Disease: A Systematic Review

BACKGROUND

Clinicians are increasingly considering using frailty assessments to individualize treatment for older patients. It remains uncertain whether interventions to reduce cardiovascular disease (CVD) events offer similar benefits between older adults with and without frailty.

METHODS

A systematic literature search was undertaken in PubMed and Embase, adhering to PRISMA guidelines. Key inclusion criteria were randomized controlled trials published between January 2007 and September 2024 with CVD outcomes as an endpoint and data on frailty-specific treatment effects. Data were collected for population characteristics, intervention, follow-up time, frailty measure, outcome rates, and frailty subgroup treatment effect. Due to heterogeneity among the studies, the results were not pooled.

RESULTS

The search identified 151 unique studies, of which 18 were included. Using Cochrane Risk of Bias 2.0, 12 out of the 18 studies have low risk of bias. The intervention was more effective in frail participants than in non-frail counterparts in two studies (e.g., aerobic exercise), less effective in frail participants in three studies (e.g., intensive lifestyle intervention), similarly effective across frailty levels in seven studies (e.g., prasugrel), and inconclusive in six studies (e.g., edoxaban). Some treatments were similarly effective across frailty level by hazard ratio but had a greater reduction in absolute risk for frail versus non-frail patients.

CONCLUSIONS

Cardiovascular interventions may provide differential benefits by patients' frailty. These findings suggest the potential utility of frailty assessment for optimizing cardiovascular interventions.

Comparison of Physical Frailty Assessments in Heart Failure With Preserved Ejection Fraction

Background

Frailty is a known determinant of poor clinical outcomes in heart failure with preserved ejection fraction (HFpEF). However, prevalence estimates and effect sizes vary in part due to multiple tools available to measure frailty.

Objectives

This study aimed to compare the prevalence and prognostic value of six commonly used frailty assessments in adults with HFpEF.

Methods

We examined 203 outpatients with HFpEF seen at Weill Cornell Medicine from June 2018 to August 2022. The following frailty scales were compared: the Clinical Frailty Scale (CFS), the Fatigue, Resistance, Ambulation, Illnesses, and Loss of Weight scale (FRAIL) scale, the 5-m gait speed test, the 5 timed sit-to-stand test, hypoalbuminemia, and the modified body mass index score. The primary endpoint was a 1-year composite of all-cause mortality and hospitalization. Cox proportional hazard models were used to examine the association between frailty and the primary endpoint, adjusting for race and the MAGGIC (Meta-Analysis Global Group in Chronic) heart failure prognostic risk score.

Results

The median age was 76.7 years (IQR: 69.7-83.9 years). The prevalence of frailty ranged from 21.2% (hypoalbuminemia) to 77.8% (5 timed sit-to-stand) and increased with advancing HFpEF severity. Of the 6 frailty assessments, the CFS (HR: 2.83; 95% CI: 1.61-4.98, P < 0.001), FRAIL scale (HR: 1.96; 95% CI: 1.25-3.07, P = 0.004), and 5-m gait speed test (HR: 2.80; 95% CI: 1.50-5.25, P = 0.001) were associated with adverse outcomes in the multivariate analysis.

Conclusions

Frailty assessments yield a wide range of prevalence estimates and vary in their associations with clinical outcomes. The CFS, FRAIL scale, and the 5-m gait speed tests demonstrated associations with adverse outcomes and may thus be reasonable tools for routine use in patients with HFpEF.

Effect of a new resistance training method on the metaboreflex in cardiac rehabilitation patients: a randomized controlled trial

Patients with cardiac disease exhibit exaggerated sympathoexcitation, pressor, and ventilatory responses to muscle metaboreflex activation (MMA). However, the effects of cardiac rehabilitation (CR) and especially resistance training (RT) modalities on MMA are not well known. This study investigated how CR impacts MMA in such patients, specifically examining the effects of two different resistance training (RT) protocols following 12 weeks of CR. In addition to endurance exercises, 32 patients were randomized into either a 3/7 RT modality (comprising 5 sets of 3-7 repetitions) or a control (CTRL) modality (involving 3 sets of 9 repetitions), with distinct inter-set rest intervals (15 s for 3/7 and 60 s for CTRL). MMA, gauged by blood pressure (BP) and ventilatory (Ve) responses during a handgrip exercise at 40% effort and subsequent post-exercise circulatory occlusion, demonstrated CR's significant impact. Systolic BP, initially at + 28 ± 23% pre-CR, improved to + 11 ± 15% post-CR (P = .011 time effect; P = .131 group effect). Diastolic BP showed a similar trend, from + 27 ± 23% to + 13 ± 15% (P = .099 time effect; P = .087 group effect). Ve, initially at + 60 ± 39%, reduced to + 14 ± 19% post-CR (P < .001 time effect; P = .142 group effect). Critical parameters-maximal oxygen consumption, lean mass, hand grip, and quadriceps strength-exhibited parallel increases in both 3/7 and CTRL groups (P < .05 time effect; P > .3 group effect). Ultimately, CR demonstrated comparable improvements in MMA across both RT modalities, indicating its positive influence on cardiovascular responses and physical performance in individuals with cardiac conditions.

Various Forms of Cardiac Rehabilitation and Their Effect on Frailty Syndrome in Cardiac Patients-A Systematic Review

Background: The growing population of the elderly is accompanied by an increase in the number of people with frailty syndrome. Apart from advanced age, the occurrence of cardiovascular diseases is also one of the agents favorable to frailty that is a factor aggravating the disease prognosis. However, it is worth noting that this is an agent changeable by, i.a., movement rehabilitation. Cardiac rehabilitation (CR) based on comprehensiveness, early implementation, and multiplicity is standard intervention in patients with cardiovascular diseases. In cardiac patients with accompanying frailty or pre-frailty syndrome, it is worth making efforts to upgrade the CR program. Methods: Studies on the effect of cardiac rehabilitation or its modifications on the level of frailty of patients with cardiovascular disease were analyzed. Results: Training programs based on endurance training should be supplemented by resistance, balance, mobility, and respiratory exercises. Furthermore, it is important to educate patients about the need to increase daily physical activity. This review presents different approaches to CR (traditional CR, multicomponent training, training with a HAL (Hybrid Assistive Limb), and prehabilitation) and their impact on frailty score. Summary: Early implemented and comprehensive rehabilitation allows for the improvement of the clinical state and for a decrease in overall frailty. It also guarantees safety during everyday activities. It is crucial for the fitness of the elderly to encourage them to increase daily physical activity and to exercises at home.

Cardiac rehabilitation: the gateway for secondary prevention

Cardiac rehabilitation (CR) is a multidisciplinary supervised programme which typically consists of tailored exercise and education on lifestyle management and risk factor modification in cardiac patients. Participation in CR reduces morbidity and mortality, while improving quality of life following major cardiovascular events. Despite the benefits of CR, it is underutilised, generally in the 20%-30% range for eligible patients. Participation and adherence rates are particularly suboptimal in vulnerable populations, such as those of lower socioeconomic status and women. Interventions such as automated referral to CR or hybrid/virtual programmes can increase enrolment to CR. This review summarises the components of CR and provides recommendations for providers regarding participation and adherence. To better engage a larger proportion of CR-eligible patients, CR programmes may need to expand or adjust ways to deliver secondary prevention.

Health-related quality of life in elderly cardiac patients undergoing cardiac rehabilitation and the association with exercise capacity: the EU-CaRE study

AIMS

The ability to be physically active is pivotal to the quality of life in elderly patients. This study aims to describe the association between exercise capacity and health-related quality of life (HRQoL), anxiety, and depression following an exercise-based cardiac rehabilitation (CR) programme in elderly cardiac patients.

METHODS AND RESULTS

Patients aged ≥65 years with acute and chronic coronary syndrome or heart valve surgery were consecutively included from eight CR centres in seven European countries. Exercise capacity [VO2peak(mL/kg/min)] was assessed with a cardiopulmonary exercise test (97%) or a 6-min walk test. Outcome variables included HRQoL [36-item Short-Form Health Survey physical and mental component scores (PCS and MCS)], anxiety (Generalized Anxiety Disorder-7), and depression (Patient Health Questionnaire-9). Mixed models were used to address the association between baseline and the development in VO2peak, and outcome variables stratified on sex, and adjusted for baseline values, age, and CR centre. A total of 1633 patients were included (T0), 1523 (93%) completed end-of-CR assessment (T1), and 1457 (89%) were available for 1-year follow-up (T2). Women had higher percentage of predicted VO2peak but poorer scores in HRQoL, anxiety, and depression at all time points. All scores improved in both sexes at follow-up. We found significant associations between VO2peak at baseline as well as development in VO2peak and all outcome variables at T1 and T2 in men (all P < 0.001). In women, VO2peak was only associated with PCSs (P < 0.001).

CONCLUSION

Improvements in exercise capacity were strongly associated with improvements in HRQoL and mental health, however, with stronger associations in men. The results highlight the importance of physical fitness for HRQol and mental health. The findings from this study might be useful to better target individual CR programmes.

Cardiac rehabilitation and frailty: a systematic review and meta-analysis

AIMS

Frailty among cardiac rehabilitation (CR) participants is associated with worse health outcomes. However, no literature synthesis has quantified the relationship between frailty and CR outcomes. The purpose of this study was to examine frailty prevalence at CR admission, frailty changes during CR, and whether frailty is associated with adverse outcomes following CR.

METHODS AND RESULTS

We searched CINAHL, EMBASE, and MEDLINE for studies published from 2000 to 2023. Eligible studies included a validated frailty measure, published in English. Two reviewers independently screened articles and abstracted data. Outcome measures included admission frailty prevalence, frailty and physical function changes, and post-CR hospitalization and mortality. Observational and randomized trials were meta-analysed separately using inverse variance random-effects models. In total, 34 peer reviewed articles (26 observational, 8 randomized trials; 19 360 participants) were included. Admission frailty prevalence was 46% [95% CI 29-62%] and 40% [95% CI 28-52%] as measured by Frailty Index and Kihon Checklist (14 studies) and Frailty Phenotype (11 studies), respectively. Frailty improved following CR participation (standardized mean difference (SMD): 0.68, 95% CI 0.37-0.99; P < 0.0001; six studies). Meta-analysis of observational studies revealed higher admission frailty and increased participants' risk of all-cause mortality (hazard ratio: 9.24, 95% CI 2.93-29.16; P = 0.0001; four studies). Frailer participants at admission had worse physical health outcomes, but improved over the course of CR.

CONCLUSION

High variability in frailty tools and CR designs was observed, and randomized controlled trial contributions were limited. The prevalence of frailty is high in CR and is associated with greater mortality risk; however, CR improves frailty and physical health outcomes.

Artificial Intelligence (AI)-Driven Frailty Prediction Using Electronic Health Records in Hospitalized Patients With Cardiovascular Disease

Background

This study aimed to create a deep learning model for predicting phenotypic physical frailty from electronic medical record information in patients with cardiovascular disease.

Methods and Results

This single-center retrospective study enrolled patients who could be assessed for physical frailty according to cardiovascular health study criteria (25.5% [691/2,705] of the patients were frail). Patients were randomly separated for training (Train set: 80%) and validation (Test set: 20%) of the deep learning model. Multiple models were created using LightGBM, random forest, and logistic regression for deep learning, and their predictive abilities were compared. The LightGBM model had the highest accuracy (in a Test set: F1 score 0.561; accuracy 0.726; area under the curve of the receiver operating characteristics [AUC] 0.804). These results using only commonly used blood biochemistry test indices (in a Test set: F1 score 0.551; accuracy 0.721; AUC 0.793) were similar. The created models were consistently and strongly associated with physical functions at hospital discharge, all-cause death, and heart failure-related readmission.

Conclusions

Deep learning models derived from large sample sizes of phenotypic physical frailty have shown good accuracy and consistent associations with prognosis and physical functions.

Effectiveness of Tai Chi exercise on balance, falls, and motor function in older adults: a meta-analysis

Objective

This study systematically evaluated Tai Chi's effects on balance, fall prevention, and physical function in older adults.

Methods

A comprehensive literature search of PubMed, Web of Science, and EMbase databases included randomized controlled trials published up to August 2024. The meta-analysis used RevMan 5.4 and applied the GRADE framework to assess evidence quality.

Results

Twenty-two studies met the criteria. Tai Chi significantly improved balance and physical function, particularly in the Berg Balance Scale (BBS), one-leg standing with eyes closed (OLS-C), and Timed up-and-go test (TUG). Fear of falling (FOF) also reduced, though changes in Tinetti Balance Test (TBT) and Short Physical Performance Battery (SPPB) were not statistically significant.

Conclusion

Tai Chi effectively enhances balance and physical function in older adults, with notable potential for fall risk reduction. While some tests showed no significant effect, overall results support Tai Chi as a valuable intervention to promote older adults' health.
