Cardiac Rehabilitation in the Elderly

Factors influencing active participation in cardiac rehabilitation among patients with cardiovascular disease: A nationwide cohort study

BACKGROUND

Cardiac rehabilitation (CR) is a well-established program for improving exercise capacity, quality of life, and long-term outcomes in patients with cardiovascular disease (CVD). Despite its proven benefits, CR participation rates remain low in many countries. Identifying the barriers to CR participation is crucial for developing effective strategies to enhance patient engagement in these programs.

OBJECTIVE

To analyze the barriers to CR participation among patients with CVD. To analyze the barriers to cardiac rehabilitation (CR) participation among patients with cardiovascular disease (CVD).

DESIGN

A nationwide cohort study using data from the Korean National Health Insurance Database.

SETTING

South Korea.

PATIENTS

In 2019, patients who received coronary revascularization at hospitals operating CR program.

INTERVENTIONS

Comparison of the demographic, socioeconomic, and medical status between patients who actively participated in CR and those who did not.

MAIN OUTCOME MEASURES

The analysis considered potential influencing factors such as gender, age, residence area, income level, disability status, medical comorbidities, accompanying disease, cigarette smoking, alcohol consumption, physical activity levels, and obesity.

RESULTS

The CR participation rate was low among women, older adults, rural residents, and low-income families. In addition, the participation rate was low when there was a disability or medical comorbidity, such as hypertension, diabetes, and musculoskeletal disorders. CR participation rate was also low in patients who experienced CVD recurrence within 10 years.

CONCLUSION

CR participation is affected by medical comorbidities, in addition to gender, age, income level, and residence. In particular, participation rate is lower in patients with a high risk of CVD recurrence due to medical comorbidities.

Time trends in coronary heart disease mortality attributed to outdoor PM2.5 in China: an age-period-cohort analysis using the Global Burden of Disease Study 2019

Background

In China, coronary heart disease (CHD) is a significant public health issue affecting the population's health. Evidence suggests that outdoor PM2.5 is a crucial environmental risk factor for CHD mortality. This study aims to provide scientific evidence for the prevention and treatment of CHD by analyzing the trend of CHD mortality attributed to outdoor PM2.5 in China from 1994 to 2019.

Methods

Data were obtained from the Global Burden of Disease Study (GBD) 2019. CHD mortality attributed to outdoor PM2.5 in China from 1994 to 2019 was extracted from the GBD Data tool. We used an age-period-cohort (APC) model based on the intrinsic estimator (IE) algorithm to decompose the age, period, and cohort effects related to CHD mortality attributed to outdoor PM2.5.

Results

From 1994 to 2019, the crude mortality rates (CMRs) and age-standardized mortality rates (ASMRs) of CHD attributed to outdoor PM2.5 in China showed an overall upward trend. The APC model analysis showed that the relative risk of CHD mortality attributed to outdoor PM2.5 increased exponentially with age, reaching 89.284 (95% CI: 48.669, 163.793) in the 90-95 age group. The period effect increased monotonically, with a relative risk of 3.699 (95% CI: 3.639, 3.760) in 2019. The cohort effect decreased monotonically, with the lowest relative risk of CHD mortality attributed to outdoor PM2.5 in residents born between 1990 and 1994, at 0.135 (95% CI: 0.031, 0.588).

Conclusion

The older adult, a high-risk population, should receive more attention. In the future, continuous efforts should be made to strengthen environmental air pollution control and implement targeted health interventions to reduce the impact of outdoor PM2.5 on CHD mortality.

[Detrimental impact of acute coronary syndrome on the independence of the elderly]

Objectives

To evaluate the prognostic role of functional status in older adults hospitalized for acute coronary syndrome (ACS) and the implications of the coronary event on functional decline during follow-up.

Materials and Methods

This was a single-center, prospective cohort study including patients aged ≥65 years hospitalized for ACS with (STEMI) or without ST-segment elevation in 2022. Patients with total dependence or lacking a care network were excluded. Functional status was assessed using the Barthel Index and the Lawton and Brody scales at admission, 30 days, and one year post-discharge. The association between initial functional status and major adverse cardiovascular events (MACE) was analyzed, as well as the impact of ACS on functional status over the short and long term.

Results

A total of 110 patients older than 65 years were included (mean age 78.8±4.6 years; 61.8% male). At admission, 94.3% presented mild functional dependence according to the Barthel Index, with similar findings on the Lawton and Brody scales. At 30 days, a significant functional decline was observed (Barthel: 71.2±11.3, p<0.001; Lawton: 4.8±2.5, p=0.02), which persisted at one year. Initial functional status was not associated with MACE. ST-segment elevation ACS (STEMI) was an independent predictor of short-term functional decline (adjusted OR 1.75; p=0.04).

Conclusions

In older adults with ACS, initial functional status did not predict adverse events; however, significant functional decline was observed, particularly after STEMI. This underscores the importance of personalized strategies for managing this vulnerable population.

Effects of Water-Based Exercise on Patients Older than 60 Years Undergoing Cardiac Rehabilitation after Coronary Intervention

Cardiac rehabilitation (CR) plays a crucial role in managing patients who have undergone coronary intervention (CI) following acute myocardial infarction. While water-based exercise is gaining recognition as an exercise modality in this patient population, its impact on the subgroup of older adults remains unexplored. In this post hoc analysis, we investigated the effects of water-based exercise on adults older than 60 years undergoing CR after CI, comparing it to land-based exercise and a control group. In total, 45 patients aged over 60 participated in 14-day exercise programs, featuring two daily 30-min sessions. We assessed exercise capacity (VO2peak), vascular function (flow-mediated vasodilation (FMD)), heart rate variability (HRV), and blood markers (Interleukins 6, 8, and 10, P-Selectin, ICAM, and High-sensitivity CRP) before and after CR. VO2peak in the water-based group improved significantly after CR in comparison with the land-based group: 1.35 kg/mL/min (95% CI [0.20-2.50], p = 0.022). The significant difference between water-based and land-based groups was observed in several HRV parameters: Total power -1129.20 ms2 (95% CI [-1951.92--306.49], p = 0.008); peak LF 0.04 Hz (95% CI [0.00-0.08], p = 0.036); SD1 -9.02 millisecond (95% CI [-16.86--1.18], p = 0.025); and SD2 -19.71 ms (95% CI [-35.08--4.34], p = 0.013). FMD and blood markers did not vary significantly based on the exercise group. These findings suggest that short-term water-based CR may have potential as an alternative to traditional land-based CR, improving VO2peak and cardiorespiratory fitness among adults over 60 years undergoing CR after CI.

The State of Cardiac Rehabilitation in Saudi Arabia: Barriers, Facilitators, and Policy Implications

Cardiovascular disease (CVD) is a critical public health issue in Saudi Arabia, where it is the leading cause of death. The economic burden of CVD in the country is expected to triple by 2035, reaching $9.8 billion. This paper provides an overview of CVD in Saudi Arabia and its risk factors, impact on healthcare, and effects on patients' quality of life. The review emphasizes the potential of cardiac rehabilitation (CR) programs in addressing the CVD epidemic. CR programs have been shown to reduce morbidity, mortality, and hospital readmissions while improving patients' cardiovascular health and overall well-being. However, these programs are underutilized and inaccessible in Saudi Arabia. The paper highlights the urgent need for CR programs in the country and suggests key strategies for implementation. These include increasing patient referrals, tailoring programs to individual needs, enhancing patient education, and making CR accessible through home-based options. Fostering multidisciplinary collaboration and developing tailored guidelines for Arab countries can further enhance the impact of CR programs. In conclusion, this review underscores the vital importance of comprehensive CR programs in Saudi Arabia to combat the rising CVD burden, improve patient quality of life, and align with the goals of the Saudi 2030 Vision for a healthier society.

How to optimize the adherence to a guideline-directed medical therapy in the secondary prevention of cardiovascular diseases: a clinical consensus statement from the European Association of Preventive Cardiology

A key factor to successful secondary prevention of cardiovascular disease (CVD) is optimal patient adherence to treatment. However, unsatisfactory rates of adherence to treatment for CVD risk factors and CVD have been observed consistently over the last few decades. Hence, achieving optimal adherence to lifestyle measures and guideline-directed medical therapy in secondary prevention and rehabilitation is a great challenge to many healthcare professionals. Therefore, in this European Association of Preventive Cardiology clinical consensus document, a modern reappraisal of the adherence to optimal treatment is provided, together with simple, practical, and feasible suggestions to achieve this goal in the clinical setting, focusing on evidence-based concepts.

Effects of Cardiac Rehabilitation on Physical Fitness, Physical Function, and Self-reported Outcomes in Patients ≥80 yr: A RANDOMIZED CONTROLLED TRIAL

PURPOSE

The beneficial effects of exercise-based cardiac rehabilitation (CR) after an acute coronary syndrome (ACS) are well known, but patients ≥80 yr have been less studied. The aim was to evaluate the effects of CR on patients with ACS ≥80 yr on peak cardiorespiratory fitness (CRF), physical function, and patient-reported outcome measures (PROMs) compared with a control group.

METHODS

A total of 26 patients with ACS, median age 82 (81, 84) yr, were randomized to hospital-based CR combined with a home-based exercise program (CR group) or to a control group (C) for 4 mo. Outcomes were assessed at baseline and 4 mo and included the peak CRF (primary outcome), 6-min walk test (6MWT), muscle endurance, Timed Up and Go (TUG), Short Physical Performance Battery (SPPB), one-leg stand test, and PROMs.

RESULTS

There were no significant differences between the groups in peak CRF. The CR group improved significantly in terms of the 6MWT ( P = .04), isotonic muscle endurance ( P < .001), one-leg stand test ( P = .001), SPPB total score ( P =.03), Activities-specific Balance Confidence ( P =.01), and anxiety ( P =.03), as compared with C. There were no significant intergroup differences in the TUG, the self-reported health question or depression.

CONCLUSIONS

Patients with ACS ≥80 yr improved in walking distance, muscle endurance, physical function, and PROMs, but not in peak CRF, by participating in a CR program. These results suggest an increased referral to CR for this growing group of patients to enable preserved mobility and independence in daily living, but this needs to be confirmed in larger studies.

Factors Associated With Cardiac Rehabilitation Participation in Older Adults After Myocardial Infarction: THE SILVER-AMI STUDY

PURPOSE

Cardiac rehabilitation (CR) is a key aspect of secondary prevention following acute myocardial infarction (AMI). While there is growing evidence of unique benefits of CR in older adults, it remains underutilized. We aimed to examine specific demographic, clinical, and functional factors associated with utilization of CR among older adults hospitalized with AMI.

METHODS

Our project used data from the SILVER-AMI study, a nationwide prospective cohort study of patients age ≥75 yr hospitalized with AMI and followed them up for 6 mo after discharge. Extensive baseline data were collected on demographics, clinical and psychosocial factors, and functional and sensory impairments. The utilization of CR was collected by a survey at 6 mo. Backward selection was employed in a multivariable-adjusted logistic regression model to identify independent predictors of CR use.

RESULTS

Of the 2003 participants included in this analysis, 779 (39%) reported participating in CR within 6 mo of discharge. Older age, longer length of hospitalization, having ≤12 yr of education, visual impairment, cognitive impairment, and living alone were associated with decreased likelihood of CR participation; receipt of diagnostic and interventional procedures (ie, cardiac catheterization, percutaneous coronary intervention, and coronary artery bypass graft) was associated with increased likelihood of CR participation.

CONCLUSIONS

Demographic and clinical factors, as well as select functional and sensory impairments common in aging, were associated with CR participation at 6 mo post-discharge in older AMI patients. These results highlight opportunities to increase CR usage among older adults and identify those at risk for not participating.

Cardiac rehabilitation in older adults: Apropos yet significantly underutilized

Cardiac Rehabilitation (CR) is a comprehensive disease management program that utilizes exercise training, behavioral modification, education, and psychosocial counseling to optimize outcomes and functionality in patients with cardiovascular disease (CVD)1). While CR was initially designed as an exercise training and fitness program for younger patients, usually men, after debilitating hospitalizations for myocardial infarction or cardiac surgery, evidence has expanded to also include other types of CVD in women as well as men, including heart failure, valvular disease, and peripheral arterial disease2-4). As the population of older adults continues to expand, age-related CVD is endemic and is commonly associated with exercise decline, diminished quality of life, and dependence. CR has the potential to counterbalance these patterns, and therefore stands out as a particularly important consideration for older adults with CVD. Nevertheless, CR remains highly underutilized5,6). Novel approaches to CR including home-based and hybrid CR programs show promise for enhanced outreach to patients who may not otherwise participate. This review summarizes the current data available regarding CR in older adults with CVD with a focus on geriatric-specific complexities, current barriers to utilization, and approaches to enhance participation and effectiveness.

Cardiac rehabilitation in heart failure: Indications for exercise training based on heart failure phenotype

Exercise intolerance with dyspnea and fatigue is pervasive amongst individuals with heart failure (HF) due to both central and peripheral mechanisms. Cardiac rehabilitation (CR) is a cornerstone therapy for numerous cardiovascular disease (CVD) processes, and it's use in HF with reduced ejection fraction (HFrEF) has shown significant benefit in improved mortality and quality of life (QoL). Less is known about the benefit of CR in the setting of HF with preserved ejection fraction (HFpEF), and optimal exercise therapy (ET) may vary based on underlying disease phenotype. Here we offer review of existing data for ET in both HFrEF and HFpEF with proposed exercise treatment modalities based on underlying comorbidities and variable phenotypes.

Cardiovascular Aging and Physical Activity: Insights From Metabolomics

The purpose of this review is to explore how metabolomics can help uncover mechanisms through which physical activity may influence the progression of cardiovascular aging. Cardiovascular aging is a process of functional and structural changes in older adults which can progress to cardiovascular disease. Metabolomics profiling is an investigative tool that can track the diverse changes which occur in human biochemistry with physical activity and aging. This mini review will summarize published investigations in metabolomics and physical activity, with a specific focus on the metabolic pathways that connect physical activity with cardiovascular aging.

Self-perceived cognitive status and cognitive challenges associated with cardiac rehabilitation management: experiences of elderly myocardial infarction patients

PURPOSE

The study aimed to explore the self-perceived cognitive status and cognitive challenges associated with lifestyle changes in cardiac rehabilitation among elderly myocardial infarction (MI) patients (≥65 years). Further, the study explored coping strategies developed to manage these challenges in the everyday life.

METHODS

Nine patients were included in the study. Data were collected by telephone or in person, between 6 and 12 weeks post MI, using semi-structured interviews. Data were analysed inductively, using thematic analysis.

RESULTS

Four major themes were identified, highlighting elderly MI patients' experiences of their cognitive status and cardiac rehabilitation management: (1) A change in cognition over time, (2) Situating the MI within a challenging and changing life context, (3) Navigating the hurdles of cardiac rehabilitation, and (4) Being seen within the healthcare system.

CONCLUSION

Elderly MI patients are situated in a complex life context, dealing with a transition to retirement, multiple health issues and age-related cognitive decline. In this context, the MI experience is marginalised, and cognitive decline normalized. By adopting individually tailored interventions and improving healthcare provider continuity and accessibility, cognitive challenges associated with cardiac rehabilitation could be easier to overcome.IMPLICATIONS FOR REHABILITATIONSelf-perceived cognitive impairment, in particular regarding memory, seems fairly common among elderly MI patients and should likely be identified prior to hospital discharge in order to optimize the prospects of self-care.There seems to exist an unmet need to implement the practice of individually adapted education and information further, in accordance with current recommendations for elderly cardiac patients.The overall health and cognitive status, social network and the objective living conditions (e.g., distance from service and housing) should be taken into account when planning the patient's cardiac rehabilitation management.Healthcare providers likely need to strengthen the continuity of care and increase its accessibility for elderly MI patients, in particular following the transfer from hospital care to local health centres.

Review of Trials on Exercise-Based Rehabilitation Interventions Following Acute Decompensated Heart Failure: OBSERVATIONS FROM THE WHO INTERNATIONAL CLINICAL TRIALS REGISTRY PLATFORM

PURPOSE

Cardiac rehabilitation is an important intervention for patients with heart failure. However, its clinical application in acute decompensated heart failure (ADHF) remains underutilized with limited research available. An assessment of current research in this area will help guide future investigations. The aim of this review is to summarize the current research focusing on rehabilitation interventions following recovery from ADHF.

REVIEW METHODS

A systematic search was carried out on all trials registered in the clinical trial registry database of the World Health Organization-International Clinical Trial Registry Platform (WHO-ICTRP). Studies focusing on ADHF and utilizing any exercise and rehabilitation-based intervention were included.

RESULTS

A majority of 11 trial protocols, including 3827 participants with low ejection fraction (<40%), were identified from the WHO-ICTRP database. Majority of the protocols (64%) focused on exercise-based interventions with approximately one-quarter (29%) focusing on neuromuscular electrical stimulation and one on noninvasive ventilation during exercise. Irrespective of the mode of exercise, all protocols employed low-moderate intensity training with outcomes focusing on physical function and quality of life.

CONCLUSION

Studies on rehabilitative interventions for ADHF are still in their early stages. More research is needed using innovative methodologies and testing for feasibility and fidelity.

Benefits of Cardiac Rehabilitation on Functional Status and Mood Disorders in Elderly and Very Elderly Patients: A PROSPECTIVE COHORT STUDY

PURPOSE

Patients ≥80 yr are not frequently referred for cardiac rehabilitation (CR). This study aimed to describe the benefit of CR in the very elderly population in comparison with patients ≤65 and 66-79 yr in terms of gain in functional status and improvement of mood disorders.

METHODS

We conducted a prospective, cohort, single-center study. Physical performance was evaluated with a 6-min walk test (6MWT). Anxiety, depression, and overall psychological distress were evaluated with Hospital Anxiety and Depression Scale (HADS) scores. Primary outcomes were the percent improvement in the predicted distance and the reduction in the prevalence of anxiety, depression, and overall psychological distress.

RESULTS

There were 45 (9%) patients ≥80 yr among 499 participants. There were no significant differences in the percent improvement of the predicted distance in the 6MWT among age groups, being +15 (7, 25)%, +15 (7, 25)%, and +10 (4, 26)% for ≤65, 66-79, and ≥80-yr groups, respectively (P = .11). The elderly group had a higher prevalence of depression, anxiety, and overall psychological distress (72%, 51%, and 38%, respectively). After CR, there was a significant improvement in HADS scores in all groups. The prevalence of depression was reduced by 38%, anxiety by 60%, and overall psychological distress by 58%.

CONCLUSION

Patients ≥80 yr have decreased physical performance and a higher prevalence of mood disorders than their younger counterparts. Nevertheless, they improved significantly in all outcomes measured.

Offering, participation and adherence to cardiac rehabilitation programmes in the elderly: a European comparison based on the EU-CaRE multicentre observational study

AIMS 

Cardiac rehabilitation (CR) is strongly recommended but participation of elderly patients has not been well characterized. This study aims to analyse current rates and determinants of CR referral, participation, adherence, and compliance in a contemporary European cohort of elderly patients.

METHODS AND RESULTS 

The EU-CaRE observational study included data from consecutive patients aged ≥ 65 with acute coronary syndrome, revascularization, stable coronary artery disease, or heart valve replacement, recruited in eight European centres. Rates and factors determining offering, participation, and adherence to CR programmes and compliance with training sessions were studied across centres, under consideration of extensive-outpatient vs. intensive-inpatient programmes. Three thousand, four hundred, and seventy-one patients were included in the offering and participation analysis. Cardiac rehabilitation was offered to 80.8% of eligible patients, formal contraindications being the main reason for not offering CR. Mean participation was 68.0%, with perceived lack of usefulness and transport issues being principal barriers. Mean adherence to CR programmes of participants in the EU-CaRE study (n = 1663) was 90.3%, with hospitalization/physical impairment as principal causes of dropout. Mean compliance with training sessions was 86.1%. Older age was related to lower offering and participation, and comorbidity was associated with lower offering, participation, adherence, and compliance. Intensive-inpatient programmes displayed higher adherence (97.1% vs. 85.9%, P < 0.001) and compliance (full compliance: 66.0% vs. 38.8%, P < 0.001) than extensive-outpatient programmes.

CONCLUSION 

In this European cohort of elderly patients, older age and comorbidity tackled patients' referral and uptake of CR programmes. Intensive-inpatient CR programmes showed higher completion than extensive-outpatient CR programmes, suggesting this formula could suit some elderly patients.

Differences in Comorbid Conditions Among Older Adult Participants in Cardiac Rehabilitation

PURPOSE

Most older adults eligible for cardiac rehabilitation (CR) do not participate or participate with low frequency, although it is a standard of care for patients with cardiovascular disease (CVD). Identifying the barriers to older adult participation is key in improving CR efficacy.

METHODS

A range of patient characteristics was analyzed in relation to on-site frequency of participation in a CR program by older adult patients. These characteristics included demographics and indications for referral, as well as CVD and non-CVD diagnoses. The prevalence of these characteristics was compared among three patient cohorts, ranging from high contact frequency to minimal contact frequency of on-site participation in CR.

RESULTS

Among the three participation frequency cohorts, no differences were noted in demographic factors, indications for referral, or CVD diagnoses. However, patients with hearing impairment (OR = 4.15: 95% CI, 1.32-13.08) or visual impairment (OR = 4.11: 95% CI, 1.46-11.59) at time of enrollment were more likely to be found in the minimal contact cohorts than the moderate or high contact frequency cohorts.

CONCLUSIONS

Whereas differences in CVD had little bearing on frequency of CR participation in older patients, differences in hearing and visual impairment varied significantly. Patients with hearing and vision impairments attended less frequently. Sensory impairment has previously been demonstrated to impact health care utilization by older adults, but is rarely considered in the treatment of CVD or CR. As sensory impairments are extremely prevalent among geriatric patients, further study of these potential barriers to care might open possibilities for older adult participation in CR.

Clinical and Demographic Trends in Cardiac Rehabilitation: 1996-2015

PURPOSE

Clinical interventions in programs such as cardiac rehabilitation (CR) are guided by clinical characteristics of participating patients. This study describes changes in CR participant characteristics over 20 yr.

METHODS

To examine changes in patient characteristics over time, we analyzed data from 1996 to 2015 (n = 5396) garnered from a systematically and prospectively gathered database. Linear, logistic, multinomial logistic or negative binomial regression was used, as appropriate. Effects of sex and index diagnosis were considered both as interactions and as additive effects.

RESULTS

Analyses revealed that mean age increased (from 60.7 to 64.2 yr), enrollment of women increased (from 26.8% to 29.6%), and index diagnosis has shifted; coronary artery bypass surgery decreased (from 37.2% to 21.6%), whereas heart valve repair/replacement increased (from 0% to 10.6%). Risk factors also shifted with increases in body mass index (28.7 vs 29.6 kg/m), obesity (from 33.2% to 39.6%), hypertension (from 51% to 62.5%), type 2 diabetes mellitus (from 17.3% to 21.7%), and those reporting current smoking (from 6.6% to 8.4%). Directly measured peak aerobic capacity remained relatively stable throughout. The proportion of patients on statin therapy increased from 63.6% to 98.9%, coinciding with significant improvements in lipid levels.

CONCLUSIONS

Compared with 1996, participants entering CR in 2015 were older, more overweight, and had a higher prevalence of coronary risk factors. Lipid values improved substantially concurrent with increased statin use. While the percentage of female participants increased, they continue to be underrepresented. Patients with heart valve repair/replacement now constitute 10.6% of the patients enrolled. Clinical programs need to recognize changing characteristics of attendees to best tailor interventions.

Frailty is an independent risk factor for recurrence and mortality following curative resection of stage I-III colorectal cancer

AIM

With population aging, the number of frail patients with colorectal cancer has increased. The Clinical Frailty Scale (CFS) is a validated tool for assessing frailty, and higher scores indicate worse clinical outcomes following cardiovascular procedures. This retrospective study aimed to examine preoperative frailty in relation to recurrence and mortality following curative resection of colorectal cancer.

METHODS

We retrospectively analyzed data for 729 consecutive patients undergoing curative resection of stage I-stage III colon and rectal adenocarcinoma between January 2009 and December 2016. Frailty was assessed using the CFS: 1 (very fit) to 9 (terminally ill), and frailty was defined as CFS ≥ 4. Recurrence-free survival (RFS) and overall survival (OS) were compared between frail and nonfrail patients. Cox proportional hazards model was used to calculate hazard ratios (HRs), controlling for potential confounders.

RESULTS

CFS score was negatively correlated with the Barthel index of activities of daily living (Spearman's ρ = -0.83). Of the 729 patients, 253 (35%) were frail. In multivariable analyses adjusting for potential confounders including age and disease stage, frailty was independently associated with shorter RFS (multivariable HR: 1.70, 95% confidence interval: 1.25-2.31, P < .001) and OS (multivariable HR: 2.04, 95% confidence interval: 1.40-2.99, P < .001). There were no significant interactions of frailty with age and disease stage regarding RFS and OS (P interaction > .72).

CONCLUSION

Preoperative frailty was independently associated with shorter RFS and OS following resection of nonmetastatic colorectal cancer, regardless of age and disease stage. Further trials are needed to establish treatment strategies for frail patients with colorectal cancer.

Secondary prevention through comprehensive cardiovascular rehabilitation: From knowledge to implementation. 2020 update. A position paper from the Secondary Prevention and Rehabilitation Section of the European Association of Preventive Cardiology

Secondary prevention through comprehensive cardiac rehabilitation has been recognized as the most cost-effective intervention to ensure favourable outcomes across a wide spectrum of cardiovascular disease, reducing cardiovascular mortality, morbidity and disability, and to increase quality of life. The delivery of a comprehensive and 'modern' cardiac rehabilitation programme is mandatory both in the residential and the out-patient setting to ensure expected outcomes. The present position paper aims to update the practical recommendations on the core components and goals of cardiac rehabilitation intervention in different cardiovascular conditions, in order to assist the whole cardiac rehabilitation staff in the design and development of the programmes, and to support healthcare providers, insurers, policy makers and patients in the recognition of the positive nature of cardiac rehabilitation. Starting from the previous position paper published in 2010, this updated document maintains a disease-oriented approach, presenting both well-established and more controversial aspects. Particularly for implementation of the exercise programme, advances in different training modalities were added and new challenging populations were considered. A general table applicable to all cardiovascular conditions and specific tables for each clinical condition have been created for routine practice.

Changes in Aerobic Capacity Over Time in Elderly Patients With Acute Myocardial Infarction During Cardiac Rehabilitation

OBJECTIVE

To test the hypothesis that a longer duration of phase II cardiac rehabilitation is required to recover the exercise capacity of elderly patients compared to younger patients.

METHODS

We retrospectively reviewed and analyzed the medical records of patients who were referred to our cardiac rehabilitation (CR) center and underwent percutaneous coronary intervention for acute myocardial infarction (AMI). A total of 70 patients were enrolled who underwent an exercise tolerance test (ETT) 3 weeks after the occurrence of an AMI (T0), 6 weeks after the first ETT (T1), and 12 weeks after the first ETT (T2). Patients older than 65 years were assigned to the elderly group (n=24) and those aged 65 years and younger to the younger group (n=46). Both groups performed center-based or home-based CR for 12 weeks (3 times per week and 1 session per day). Exercise intensity for each individual was based on the target heart rate calculated by the Karvonen formula. The change in maximal metabolic equivalents (METmax) of the two groups was measured at each assessment point (T0, T1, and T2) to investigate the recovery of exercise capacity.

RESULTS

The younger group showed improvement in METmax between T0 and T1. However, METmax of the elderly group showed no significant improvement between T0 and T1. The exercise capacity, measured with METmax, of all groups showed improvement between T0 and T2.

CONCLUSION

Elderly patients with AMI need a longer duration of CR (>6 weeks) than younger patients with AMI.

Cardiac rehabilitation of elderly patients in eight rehabilitation units in western Europe: Outcome data from the EU-CaRE multi-centre observational study

Aims

The European Cardiac Rehabilitation in the Elderly (EU-CaRE) HORIZON 2020 project compares the sustainable effects of cardiac rehabilitation (CR) in elderly patients.

Methods and results

A total of 1633 patients with coronary artery disease (CAD) or heart valve replacement (HVR), with or without revascularization, aged 65 or above, who participated in CR were included. Peak oxygen uptake (VO2peak), smoking, body mass index, diet, physical activity, serum lipids, psychological distress and medication were assessed before and after CR (T0 and T1) and after 12 months (T2). Patients undergoing coronary artery bypass surgery or surgical HVR had lower VO2peak at T0 and a greater increase to T1 and T2 (2.8 and 4.4 ml/kg/min, respectively) than CAD patients undergoing percutaneous or no revascularization (1.6 and 1.4 ml/kg/min, respectively). After multivariable adjustment, earlier CR uptake was associated with greater improvements in VO2peak. The proportion of CAD patients with three or more uncontrolled risk factors declined from 58.4% at T0 to 40.1% at T2 ( p < 0.0001). Psychological distress scores all improved and adherence to medication was overall good at all sites. There were significant differences in risk factor burden across sites, but no CR program was superior to others.

Conclusions

The outcomes of VO2peak in CR programs across Europe seemed mainly determined by timing of uptake and were maintained or even further improved at 1-year follow-up. Despite significant improvements, 40.1% of CAD patients still had three or more risk factors not at target after 1 year. Differences across sites could not be ascribed to characteristics of the CR programs offered.

Peak Work Rate during Exercise Could Detect Frailty Status in Elderly Patients with Stable Heart Failure

The Kihon Checklist (KCL) is a reliable tool for determining frailty status in the elderly. However, there is no information in the literature about the relationship between frailty status and exercise capacity. Here, we examined the associations between cardiopulmonary exercise testing parameters and frailty status in elderly patients with stable heart failure (HF).Ninety-two elderly patients with stable HF were evaluated using cardiopulmonary exercise testing and the KCL. A KCL score of 0-3 was classified as robust, 4-7 as pre-frail, and ≥ 8 as frail.Mean age, peak VO₂, and KCL score were 81.7 years, 13.2 mL/kg/minute, and 10.7, respectively. KCL score was significantly correlated with peak VO₂ (r = -0.527, P < 0.001) and peak work rate (r = -0.632, P < 0.001). In patients with frailty (n = 63), the peak work rate (WR) was significantly lower than it was in patients without frailty (n = 29; 39.9 versus 69.5 W, respectively; P < 0.001). Multivariate analysis revealed that peak WR and peak systolic blood pressure were significant, independent predictors of frailty (β = -0.108 and -0.045, respectively). In a diagnostic performance plot analysis, a cutoff value for peak WR of 51.9 W was the best predictor of frailty.Frailty status was significantly associated with peak WR and peak systolic blood pressure in elderly patients with stable HF. Therefore, cardiopulmonary exercise testing may be useful for assessing frailty status in this patient population.

Gender Disparities in Cardiac Rehabilitation Among Older Women: Key Opportunities to Improve Care

Older women with cardiovascular disease experience lower referral, participation, and completion rates of cardiac rehabilitation (CR), despite its well-established benefits (improved morbidity, mortality, quality of life, and functional capacity). Multiple social and health care system barriers affect participation of this population, including limitations in accessibility and transportation, competing responsibilities as caregivers, and lack of insight among patients and provider regarding the value of CR. With continued advances in technology and the ubiquity of smartphones, alternative CR programs may be able to better overcome barriers that affect older women.

Possibility of Cardio-renal Protection by Long-term Cardiac Rehabilitation in Elderly Patients with Cardiovascular Diseases

Objective Cardiac rehabilitation (CR) improves the mortality in patients with cardiovascular disease (CVD). Even in elderly patients with CVD, CR may improve the activities of daily living (ADL). Methods Eighty-eight outpatients over 65 years of age at the beginning of a CR program (baseline) at Fukuoka University Hospital who had CVD and could be followed-up for up to 5 years were enrolled. CVD included ischemic heart disease, postoperative valvular heart disease, dissecting aneurysm of the aorta and peripheral artery disease. The patients were divided into 2 groups according to the average estimated glomerular filtration rate (eGFR) at baseline (55.4±14.8 mL/min/1.73 m²): high (≥55.4, n=44) and low (<55.4, n=44)-eGFR groups. The anaerobic threshold (AT) during exercise and left ventricular ejection fraction (LVEF) were measured by cardiopulmonary exercise (CPX) and ultrasound cardiography, respectively. The serum brain natriuretic protein (BNP) was also measured every year. Results The average age at baseline in all patients was 73±6 years. In all patients, the level of eGFR did not significantly change for 5 years (55±15 mL/min/1.73 m² at baseline vs. 48±14 at the end of the study). The AT (3.7±1.0 METs at baseline vs. 3.3±0.5), LVEF (57±13% vs. 64±10%) and BNP (260±452 pg/mL vs. 308±345) were also maintained for 5 years. In both the low- and high-eGFR groups, the eGFR, AT during exercise, LVEF and BNP at the end of the study were not significantly changed compared to the baseline values, although some changes were observed during the follow-up period. Conclusion Long-term CR in CVD outpatients over 65 years of age helped maintain the AT, LVEF, BNP and eGFR for 5 years. CR afforded cardio-renal protection in elderly patients with CVD.

Tailoring Assessments and Prescription in Cardiac Rehabilitation for Older Adults: The Relevance of Geriatric Domains

Older adults have distinctive health challenges that are relevant to the prevention and treatment of cardiovascular diseases and are potentially modifiable by cardiac rehabilitation. Cardiac rehabilitation in older adults provides opportunity to assess sarcopenia, obesity, osteoporosis, frailty, falls risk, arthritis, cognition, special senses, self-efficacy, depression, social support, polypharmacy, and nutritional adequacy. Therefore, broadening standard assessments to include these domains can help detect modifiable vulnerabilities and inform therapeutic priorities.

Development and Psychometric Evaluation of the Cardiac Rehabilitation Adherence Tool (CRAT)

Patients with cardiac diseases can achieve the greatest benefit from cardiac rehabilitation through modification of their unhealthy behaviors. This study aimed to develop and examine the psychometric properties of the Cardiac Rehabilitation Adherence Tool (CRAT), which was designed to assess patients' adherence to cardiac rehabilitation. In this instrument development study, the items of the CRAT were extracted through a comprehensive literature review. The CRAT was assessed in terms of validity and reliability. Exploratory factor analysis was conducted to assess its construct validity, which led to the development of a tool containing 57 items and five dimensions including "acceptance of the rehabilitation center", "being interested in health", "feeling a need", "personal control over the situation", and "encouragement and advice." These five factors accounted for 45.23% of the observed variance. The Cronbach's alpha was 0.935. The test-retest method supported the stability of the instrument (r = 0.95). Health care professionals can use the CRAT to examine factors influencing the patient's decision to leave cardiac rehabilitation and design strategies for improving their adherence to the rehabilitation program.

Innovative Application of a Home-Based and Remote Sensing Cardiac Rehabilitation Protocol in Chinese Patients After Percutaneous Coronary Intervention

BACKGROUND

Medical care for the Chinese population has been focused on first-line activities, that is, therapy, but with little follow-up on treated patients. However, efficacy of therapy is highly dependent upon post-therapy recovery. For coronary heart disease (CHD), home-based cardiac telerehabilitation (HBCTR) is an alternative to hospital-based or center-based cardiac rehabilitation, and is an innovative approach to enhance recovery, but the approach is seldom used in China. Our preliminary survey in Shantou, China, indicated that most CHD patients showed a positive attitude toward the HBCTR technology. Our follow-up study was focused on assessing the effect of the HBCTR program in low-risk patients after percutaneous coronary intervention (PCI).

MATERIALS AND METHODS

A two-arm randomized controlled trial was conducted at the First Affiliated Hospital of the Shantou University Medical College, China. The effectiveness of this program was measured by using blood pressure, Six-Minute Walking Test (6MWT), Fagerstrom Test for Nicotine Dependence (FTND), Cardiac Depression Scale (CDS), and SF-36 Health Survey (SF36).

RESULTS

A total of 80 post-PCI patients were recruited and randomly divided into two equal groups. Based upon our effort, the usual care (UC) group received paper-based CHD educational booklets and biweekly outpatient review. The HBCTR group carried out outdoor walking/jogging exercise with real-time physiological monitoring along with CHD education materials. After the 6-week intervention, the 6MWT, SF36 (PCS, MCS), FTND and CDS in both groups were found to have significantly improved compared with baseline. In addition, the improvements in SF36, FTND scores, and 6MWT distance in the HBCTR group were significantly better than those in the UC group (p < 0.05).

CONCLUSION

Our observations indicated that the HBCTR program may be applied successfully in Chinese patients who had very little technical skills and its application may be highly cost-effective.

Cardiac rehabilitation in the elderly patient in eight rehabilitation units in Western Europe: Baseline data from the EU-CaRE multicentre observational study

BACKGROUND

Due to the progressive deconditioning, comorbidities and higher complication rates, elderly patients are in particular need of cardiac rehabilitation. We compared elderly patients (65+ years old) participating in cardiac rehabilitation, focusing on baseline characteristics, risk factor control and functional assessment.

METHODS

The EU-CaRE study is a prospective study comparing cardiac rehabilitation in eight centres across Western Europe. Consecutive patients with acute coronary syndrome, stable coronary artery disease and heart valve replacement undergoing cardiac rehabilitation were included.

RESULTS

Of 1633 patients (median age 72 years) participating, 54% had acute coronary syndrome, 33% had stable coronary artery disease and 13% followed valve replacement. Fifty-five per cent had undergone percutaneous coronary intervention and 29% coronary artery bypass grafting. Characteristics varied across centres: 23% (17-27%) were women, 4% (0-12%) were of non-European origin and 16% (4-32%) were living alone. Median time from index event to start of cardiac rehabilitation varied from 11 to 49 days (p < 0.001). Mean VO_2peak was relatively low (16 mL/kg per min) and varied significantly between the participating centres, largely unaffected by multivariable adjustment. Overall patients received guideline recommended treatment: 93% (87-97%) were on a statin and 70% (55-85%) an angiotensin-converting enzyme inhibitor/angiotensin receptor blocker. However, risk factor control was inadequate: 58% had three or more risk factors not controlled.

CONCLUSION

EU-CaRE provides a snapshot of the elderly population with heart disease participating in cardiac rehabilitation across countries in Western Europe. Risk factors and exercise capacity indicate the continued need for cardiac rehabilitation in these patients. Of concern, the lag-time to start of cardiac rehabilitation needs improvement in many centres.

Predicting Long-Term Mortality, Morbidity, and Survival Outcomes Following a Cardiac Event: A Cardiac Rehabilitation Study

Background

Cardiac rehabilitation (CR) has been shown to decrease mortality and morbidity but estimations vary. While there is significant literature supporting short-term benefits, there is not a similarly body of research as to long-term (LT) benefits. Low participation rates in CR are due to several causes and evidence demonstrating positive LT outcomes could be a catalyst to increased participation rates.

Objective

To predict LT mortality, readmission, and survival benefits associated with CR participation in a nationally certified program.

Methods

Investigators collected mortality and hospital readmission data in a retrospective study to examine a cohort of cardiac patients following a myocardial infarction (MI), MI/percutaneous coronary intervention (PCI), and coronary artery bypass graft (CABG) up to 14 years ago. Hospital electronic medical record (EMR; n = 207) were used to measure hospital readmission outcome and State Health Department records (n = 361) for mortality and survival outcomes. Participation in CR, age, gender prior history of cardiac event, and diagnosis were used to predict readmission, mortality, and survival.

Results

Approximately half (52.1%) the sample participated in CR. Participants included 72% males, average age 68 years (38-91 years), and were predominantly Non-Hispanic white. CR participants attended an average of 20 sessions. CR group differed in diagnoses MI (58.5%), CABG (57.4%) and in prior history of heart disease (25.4%) from the non-cardiac rehabilitation (NCR) group (83.2%, 25.4%, 42.2%, respectively) (P < .05). After controlling for the covariates in logistic regression analyses, the CR group independently predicted lower all-cause mortality (odds ratio, OR = 0.22, 95% CI 0.12 to 0.39) and decreased hospital readmissions (OR = 0.48, 95% CI 0.24 to 0.96). After controlling for the covariates in survival analysis, the CR group significantly contributed to decreased likelihood of death hazard (hazard ratio = 0.36, 95% CI 0.24 to 0.54). Median survivor time for the participants was 5.91 years, SD = 3.81 years.

Conclusions

Participation in CR for middle age and elderly patients is associated with increased survival, a marked decrease in all-cause mortality, and a decrease in cardiovascular-related hospital readmission. A referral to a nationally certified outpatient CR program prior to hospital discharge and early enrollment may improve LT outcomes.

Cardiac rehabilitation fitness changes and subsequent survival

Aims

Assessments of cardiac rehabilitation (CR) in coronary heart disease (CHD) cohorts usually examine mortality in aggregate. This study examines the prognosis and characteristics of patients who enrolled and completed CR, stratified by their level of improvement in cardiorespiratory fitness (CRF) by examining the characteristics, outcomes and predictors of non-response in CRF (NonRes) compared with low-responders (LowRes) and high-responders (HighRes) after CR.

Methods and results

A total of 1171 CHD patients were referred for a phase II CR programme after therapy for an acute coronary syndrome, coronary artery bypass graft procedure or a percutaneous coronary intervention between 1 January 2000 and 30 June 2013 underwent cardiopulmonary exercise testing before and after CR. This cohort was divided according to absolute improvements in CRF (i.e. change in peak oxygen consumption expressed in mL⋅kg-1⋅min-1). Mortality was analysed after 0.5-13.4 years of follow-up (mean 6.4 years). A total of 266 (23%) subjects were NonRes. After adjustment for body mass index, age, gender, left ventricular ejection fraction and baseline CRF, NonRes, and LowRes had a statistically significant three-fold and two-fold higher mortality, respectively, when compared with HighRes (HighRes 8% vs. LowRes 17% vs. NonRes 22%; P < 0.001). Age, female gender, baseline CRF, hostility, and presence of diabetes were significant predictors of NonRes and LowRes. In addition, higher waist circumference was a predictor of NonRes.

Conclusion

Significant proportions of subjects referred to CR have no/low improvement in CRF and higher associated mortality risks. Greater attention is required to increase improvements in CRF following CR and avoid NonRes.

Hospitalization-associated disability in older adults with valvular heart disease: incidence, risk factors and its association with care processes

BACKGROUND

The aim of this study was to determine the incidence and recovery of hospitalisation-associated disability (HAD), the associated risk factors, and the link with care processes in patients aged 70 years or older hospitalised with valvular heart disease (VHD).

METHODS

Prospective cohort study performed on the cardiology and cardiac surgery units of University Hospitals Leuven, Belgium. HAD was defined as the loss of independence to complete one of the Activities of Daily Living (ADLs) between hospital admission and discharge. Recovery of HAD at 30 days post hospital discharge was achieved when patients recovered their baseline ADL status (2 weeks before hospital admission) (ClinicalTrials.gov: NCT02572999).

RESULTS

Eighty patients were enrolled in the study, 77 completed the assessment at discharge and 62 responded at 30 days follow-up. Forty patients (51.9%) developed HAD; 18 of them (45.0%) recovered their baseline ADL status. The risk of HAD increased when patients were physically restrained (relative risk (RR) 1.73, 95% confidence interval (CI) 1.20-2.49), had indwelling catheters (RR 1.80, 95% CI 0.85-3.80) and received preventive pressure ulcer measures (RR 1.71, 95% CI 1.07-2.74). Patients with HAD had longer hospital stays (+3 days, p = .011) and longer use of indwelling catheters (+2 days, p = .024).

CONCLUSION

Half of the older adults with VHD developed HAD. The results indicate a potential association between HAD and care processes, which could be used as quality measures and intervention targets. Validation in larger cohort studies is recommended.

Physical Activity, Sedentary Behavior, and Inflammatory and Hemostatic Markers in Men

PURPOSE

This study aimed to determine whether higher levels of physical activity (PA) and less sedentary behavior (SB) are associated with less inflammation, indicated by inflammatory and hemostatic biomarkers, in older men.

METHODS

A cross-sectional study of 1139 men, from the British Regional Heart Study (mean ± SD age = 78 ± 5 yr), and longitudinal analyses of 490 men with two PA measures 1 yr apart were used in this study. Single fasting venous blood samples were analyzed for several biomarkers. PA and SB were measured using ActiGraph GT3X accelerometers. Total time and time spent in bouts of moderate to vigorous PA (MVPA), light PA, and SB were derived. Linear regression analyses were used to investigate associations.

RESULTS

Cross-sectionally, higher total PA, daily steps, and MVPA were all associated with lower levels of interleukin 6 (IL-6), C-reactive protein (CRP), tissue plasminogen activator (tPA), von Willebrand factor (vWF), and D-dimer, whereas higher levels of SB were associated with higher levels of IL-6, CRP, and tPA. Each additional 10 min of MVPA was associated with a 3.2% lower IL-6 (95% confidence interval [CI] = -4.5% to -1.8%), 5.6% lower CRP (95% CI = -7.8 to -3.3), 2.2% lower tPA (95% CI = -3.0 to -1.4), 1.2% lower vWF (95% CI = -2.1 to -0.3), and 1.8% lower D-dimer (95% CI = -2.9 to -0.7), and for CRP, vWF, and D-dimer independently of SB. Associations between SB and IL-6 or tPA were independent of MVPA. Longer bouts of PA or SB were not more strongly associated with outcomes than shorter bouts. Longitudinal analyses were inconsistent with these findings, possibly because of power limitations.

CONCLUSION

Although PA (particularly MVPA) was generally associated with inflammatory and hemostatic biomarkers, we found no evidence that longer bouts were more important than shorter bouts.

Cardiac rehabilitation after percutaneous coronary intervention: Results from a nationwide survey

Aim:

The purpose of this study was to estimate the proportion of Norwegian coronary heart disease patients participating in cardiac rehabilitation programmes after percutaneous coronary intervention, and to determine predictors of cardiac rehabilitation participation.

Methods:

Participants were patients enrolled in the Norwegian Coronary Stent Trial. We assessed cardiac rehabilitation participation in 9013 of these patients who had undergone their first percutaneous coronary intervention during 2008–2011. Of these, 7068 patients (82%) completed a self-administered questionnaire on cardiac rehabilitation participation within three years after their percutaneous coronary intervention.

Results:

Twenty-eight per cent of the participants reported engaging in cardiac rehabilitation. Participation rate differed among the four regional health authorities in Norway, varying from 20%–31%. Patients undergoing percutaneous coronary intervention for an acute coronary syndrome were more likely to participate in cardiac rehabilitation than patients with stable angina (odds ratio 3.2; 95% confidence interval 2.74–3.76). A multivariate statistical model revealed that men had a 28% lower probability ( p<0.001) of participating in cardiac rehabilitation, and the odds of attending cardiac rehabilitation decreased with increasing age ( p<0.001). Contributors to higher odds of cardiac rehabilitation participation were educational level >12 years (odds ratio 1.50; 95% confidence interval 1.32–1.71) and body mass index>25 (odds ratio 1.19; 95% confidence interval 1.05–1.36). Prior coronary artery bypass graft was associated with lower odds of cardiac rehabilitation participation (odds ratio 0.47; 95% confidence interval 0.32–0.70)

Conclusion:

The estimated cardiac rehabilitation participation rate among patients undergoing first-time percutaneous coronary intervention is low in Norway. The typical participant is young, overweight, well-educated, and had an acute coronary event. These results varied by geographical region.

In the modern era of percutaneous coronary intervention: Is cardiac rehabilitation engagement purely a patient or a service level decision?

Aims

Despite the proven benefits of cardiac rehabilitation (CR), utilization rates remain below recommendation in the percutaneous coronary intervention cohort in most European countries. Although extensive research has been carried out on CR uptake, no previous study has investigated the factors that lead patients to attend the initial CR baseline assessment (CR engagement). This paper attempts to provide new insights into CR engagement in the growing percutaneous coronary intervention population.

Methods and results

In total, we analysed data on 59,807 patients who underwent percutaneous coronary intervention during 2013 to 2016 (mean age 65 years; 25% female). Twenty factors were hypothesized to have a direct impact on CR engagement and they were grouped into four main categories; namely socio-demographic factors, cardiac risk factors, medical status and service-level factors. A binary logistic regression model was constructed to examine the association between CR engagement and tested factors. All but one of the proposed factors had a statistically significant impact on CR engagement. Results showed that CR engagement decreases by 1.2% per year of age (odds ratio 0.98) and is approximately 7% lower (odds ratio 0.93) in female patients, while patients are 4.4 times more likely to engage if they receive a confirmed joining date (odds ratio 4.4). The final model achieved 86.6% sensitivity and 49.0% specificity with an area under the receiver operating characteristic curve of 0.755.

Conclusion

The present results highlight the important factors of the likelihood of CR engagement. This implies that future strategies should focus on factors that are associated with CR engagement.

Prioritizing Functional Capacity as a Principal End Point for Therapies Oriented to Older Adults With Cardiovascular Disease: A Scientific Statement for Healthcare Professionals From the American Heart Association

Adults are living longer, and cardiovascular disease is endemic in the growing population of older adults who are surviving into old age. Functional capacity is a key metric in this population, both for the perspective it provides on aggregate health and as a vital goal of care. Whereas cardiorespiratory function has long been applied by cardiologists as a measure of function that depended primarily on cardiac physiology, multiple other factors also contribute, usually with increasing bearing as age advances. Comorbidity, inflammation, mitochondrial metabolism, cognition, balance, and sleep are among the constellation of factors that bear on cardiorespiratory function and that become intricately entwined with cardiovascular health in old age. This statement reviews the essential physiology underlying functional capacity on systemic, organ, and cellular levels, as well as critical clinical skills to measure multiple realms of function (eg, aerobic, strength, balance, and even cognition) that are particularly relevant for older patients. Clinical therapeutic perspectives and patient perspectives are enumerated to clarify challenges and opportunities across the caregiving spectrum, including patients who are hospitalized, those managed in routine office settings, and those in skilled nursing facilities. Overall, this scientific statement provides practical recommendations and vital conceptual insights.

A Review of Interventions to Improve Enrolment and Adherence to Cardiac Rehabilitation Among Patients Aged 65 Years or Above

PURPOSE

This review provides an overview and quality assessment of existing interventions, assessing the intervention types that are most effective at increasing enrolment and adherence to cardiac rehabilitation in older patients aged ≥65 years Methods: The review of the literature was performed using electronic databases to search for randomised controlled trials that aimed to increase enrolment and/or adherence to cardiac rehabilitation in older patients aged ≥65 years. The main key words were cardiac rehabilitation, enrolment, adherence and older patients. Studies were included if; (1) the intervention targeted improving enrolment and/or adherence to at least one of the following components of the cardiac rehabilitation programme: exercise, education or maintaining lifestyle changes; (2) assess the effectiveness of an intervention on increasing enrolment and/or adherence to a cardiac rehabilitation programme or any of its components; (3) include measures for assessing enrolment and/or adherence to a cardiac rehabilitation programme or any of its components; (4) the study included patients with a mean age of ≥65 years who were deemed eligible to participate in a cardiac rehabilitation programme. Included studies could be published in any language and there were no date restrictions for included studies. Studies focusing on pharmaceutical adherence were not included for the purpose of this review.

RESULTS

Seven studies were included, with four investigating enrolment (1944 participants) and three assessing adherence to intervention programmes (410 participants). Three studies (1919 participants) reported higher enrolment to cardiac rehabilitation in the intervention group. Two studies that reported increases in enrolment to cardiac rehabilitation were deemed to have an unclear or high risk of bias. All three studies (410 participants) reported better adherence to cardiac rehabilitation in the intervention group when compared to the control group. Two studies that reported better completion of cardiac rehabilitation were deemed to have an unclear or high risk of bias. No formal meta-analysis was conducted due to the observed multiple heterogeneity among outcome measures, the low number of included studies and variability in study designs.

CONCLUSION

This review found only weak evidence to suggest that interventions can increase enrolment or adherence to cardiac rehabilitation programmes for patients aged ≥65 years, therefore no practice recommendations could be made and further high-quality research is needed in this population group.

Growing Relevance of Cardiac Rehabilitation for an Older Population With Heart Failure

Cardiac rehabilitation (CR) is a comprehensive lifestyle program that can have particular benefit for older patients with heart failure (HF). Prevalence of HF is increasingly common among older adults. Mounting effects of cardiovascular risk factors in older age as well as the added effects of geriatric syndromes such as multimorbidity, frailty, and sedentariness contribute to the high incidence of HF as well as to management difficulty. CR can play a decisive role in improving function, quality of life, symptoms, morbidity, and mortality, and also address the idiosyncratic complexities of care that often arise in old age. Unfortunately, the current policies and practices regarding CR for patients with HF are limited to HF with reduced ejection fraction and do not extend to HF with preserved ejection fraction, which is likely undercutting its full potential to improve care for today's aging population. Despite the strong rationale for CR on important clinical outcomes, it remains underused, particularly among older patients with HF. In this review, we discuss both the potential and the limitations of contemporary CR for older adults with HF.

Internet-based training of coronary artery patients: the Heart Cycle Trial

Low adherence to cardiac rehabilitation (CR) might be improved by remote monitoring systems that can be used to motivate and supervise patients and tailor CR safely and effectively to their needs. The main objective of this study was to evaluate the feasibility of a smartphone-guided training system (GEX) and whether it could improve exercise capacity compared to CR delivered by conventional methods for patients with coronary artery disease (CAD). A prospective, randomized, international, multi-center study comparing CR delivered by conventional means (CG) or by remote monitoring (IG) using a new training steering/feedback tool (GEx System). This consisted of a sensor monitoring breathing rate and the electrocardiogram that transmitted information on training intensity, arrhythmias and adherence to training prescriptions, wirelessly via the internet, to a medical team that provided feedback and adjusted training prescriptions. Exercise capacity was evaluated prior to and 6 months after intervention. 118 patients (58 ± 10 years, 105 men) with CAD referred for CR were randomized (IG: n = 55, CG: n = 63). However, 15 patients (27 %) in the IG and 18 (29 %) in the CG withdrew participation and technical problems prevented a further 21 patients (38 %) in the IG from participating. No training-related complications occurred. For those who completed the study, peak VO₂ improved more (p = 0.005) in the IG (1.76 ± 4.1 ml/min/kg) compared to CG (-0.4 ± 2.7 ml/min/kg). A newly designed system for home-based CR appears feasible, safe and improves exercise capacity compared to national CR. Technical problems reflected the complexity of applying remote monitoring solutions at an international level.

Cardiac Rehabilitation Delivery Model for Low-Resource Settings: An International Council of Cardiovascular Prevention and Rehabilitation Consensus Statement

Cardiovascular disease (CVD) is a global epidemic, which is largely preventable. Cardiac rehabilitation (CR) is demonstrated to be efficacious and cost-effective for secondary prevention in high-income countries. Given its affordability, CR should be more broadly implemented in middle-income countries as well. Hence, the International Council of Cardiovascular Prevention and Rehabilitation (ICCPR) convened a writing panel to recommend strategies to deliver all core CR components in low-resource settings, namely: (1) initial assessment, (2) lifestyle risk factor management (i.e., diet, tobacco, mental health), (3) medical risk factor management (lipids, blood pressure), (4) education for self-management; (5) return to work; and (6) outcome evaluation. Approaches to delivering these components in alternative, arguably lower-cost settings, such as the home, community and primary care, are provided. Recommendations on delivering each of these components where the most-responsible CR provider is a non-physician, such as an allied healthcare professional or community health care worker, are also provided.

Does cardiac rehabilitation favour the young over the old?

BACKGROUND

Although cardiac rehabilitation (CR) is a proven intervention in reducing cardiovascular mortality and morbidity there is concern that CR programme delivery may not yield comparable outcomes across age groups.

PURPOSE

This study sought to determine if the outcomes achieved after completing CR were influenced by age in patients with coronary heart disease.

METHOD

Patients were stratified into 2 age groups: young (18-65 years) and elderly (>65 years). Pre-CR and post-CR assessments were used to compute changes in 9 CR outcomes (body mass index (BMI), waist size, hyperlipidaemia, hypertension, smoking, walking fitness, physical activity, anxiety and depression). Pearson's χ(2) test was used to examine the association between the age groups and outcome. Data was extracted from the UK National Audit from July 2010 to June 2015.

RESULTS

A total of 203 012 young patients (55.1±7.9 years, 78% male) and 262 813 elderly patients (76.1±6.9 years, 63.9% male) were analysed. Young patients had a better ratio of improvement across a wide range of risk factors in particular smoking cessation (OR=3.3, p<0.001) while elderly patients had a better ratio of improvement in body shape risk factors BMI (OR=1.3, p<0.001), waist size in women (OR=1.3, p=0.016).

CONCLUSIONS

Age is a significant predictor of outcomes following CR. While elderly patients achieve better outcomes in body shape risk factors, younger patients clearly achieve better outcomes across a wider range of risk factors in particular smoking cessation.
