Exercise-based cardiac rehabilitation for very old patients (> or =75 years): focus on physical function

Inflammation as a New Therapeutic Target among Older Patients with Ischemic Heart Disease

Cardiovascular (CV) diseases remain a global health challenge, with ischemic heart disease (IHD) being the primary cause of both morbidity and mortality. Despite optimal pharmacological therapy, older patients with IHD exhibit an increased susceptibility to recurrent ischemic events, significantly impacting their prognosis. Inflammation is intricately linked with the aging process and plays a pivotal role in the evolution of atherosclerosis. Emerging anti-inflammatory therapies have shown promise in reducing ischemic events among high-risk populations. This review aims to explore the potential of targeted anti-inflammatory interventions in improving clinical outcomes and the quality of life for older patients with IHD.

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 disease^2-4). 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 underutilized^5,6). 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 for older adults: current evidence and future potential

INTRODUCTION

Growth of the older adult demographic has resulted in an increased number of older patients with cardiovascular disease (CVD) in combination with comorbid diseases and geriatric syndromes. Cardiac rehabilitation (CR) is utilized to promote recovery and improve outcomes, but remains underutilized, particularly by older adults. CR provides an opportunity to address the distinctive needs of older adults, with focus on CVD as well as geriatric domains that often dominate management and outcomes.

AREAS COVERED

Utility of CR for CVD in older adults as well as pertinent geriatric syndromes (e.g. multimorbidity, frailty, polypharmacy, cognitive decline, psychosocial stress, and diminished function) that affect CVD management.

EXPERT OPINION

Mounting data substantiate the importance of CR as part of recovery for older adults with CVD. The application of CR as a standard therapy is especially important as the combination of CVD and geriatric syndromes catalyzes functional decline and can trigger progressive clinical deterioration and dependency. While benefits of CR for older adults with CVD are already evident, further reengineering of CR is necessary to better address the needs of older candidates who may be frail, especially as remote and hybrid formats of CR are becoming more widespread.

Cardiac rehabilitation for coronary artery disease: latest updates

PURPOSE OF REVIEW

To summarize recent innovations in cardiac rehabilitation and provide a view towards the future of cardiac rehabilitation as it adjusts to the pressures of a global pandemic.

RECENT FINDINGS

Although cardiac rehabilitation has been shown to result in a mortality benefit, research continues to enumerate the benefits of cardiac rehabilitation to patient function and quality of life in a growing range of cardiovascular diseases. In addition, new methodologies and new models of cardiac rehabilitation have emerged with the goal of increasing patient referral and participation.

SUMMARY

Cardiac rehabilitation continues to evolve and adapt to serve a growing and diversifying number of patients with cardiovascular disease with the goal of both decreasing mortality and improving patient function.

Cardiovascular disease subtypes, physical disability and workforce participation: A cross-sectional study of 163,562 middle-aged Australians

Background

Workforce participation is reduced among people with cardiovascular disease (CVD). However, detailed quantitative evidence on this is limited. We examined the relationship of CVD to workforce participation in older working-age people, by CVD subtype, within population subgroups and considering the role of physical disability.

Methods

Questionnaire data (2006–2009) for participants aged 45–64 years (n = 163,562) from the population-based 45 and Up Study (n = 267,153) were linked to hospitalisation data through the Centre for Health Record Linkage. Prior CVD was from self-report or hospitalisation. Modified Poisson regression estimated adjusted prevalence ratios (PRs) for non-participation in the workforce in people with versus without CVD, adjusting for sociodemographic factors.

Results

There were 19,161 participants with CVD and 144,401 without. Compared to people without CVD, workforce non-participation was greater for those with CVD (40.0% vs 23.5%, PR = 1.36, 95%CI = 1.33–1.39). The outcome varied by CVD subtype: myocardial infarction (PR = 1.46, 95%CI = 1.36–1.55); cerebrovascular disease (PR = 1.92, 95%CI = 1.80–2.06); heart failure (PR = 1.83, 95%CI = 1.68–1.98) and peripheral vascular disease (PR = 1.76, 95%CI = 1.65–1.88). Workforce non-participation in those with CVD versus those without was at least 21% higher in all population subgroups examined, with PRs ranging from 1.75 (95%CI = 1.65–1.85) in people aged 50–55 years to 1.21 (95%CI = 1.19–1.24) among those aged 60–64. Compared to people with neither CVD nor physical functioning limitations, those with physical functional limitations were around three times as likely to be out of the workforce regardless of CVD diagnosis; participants with CVD but without physical functional limitations were 13% more likely to be out of the workforce (PR = 1.13, 95%CI = 1.07–1.20).

Conclusions

While many people with CVD participate in the workforce, participation is substantially lower, especially for people with cerebrovascular disease, than for people without CVD, highlighting priority areas for research and support, particularly for people experiencing physical functioning limitations.

Cardiovascular rehabilitation in patients aged 70-year-old or older: benefits on functional capacity, physical activity and metabolic profile in younger vs. older patients

Background

The benefits of exercise-based cardiac rehabilitation (EBCR) programs in post-acute myocardial infarction (AMI) patients have been demonstrated. Our aim was to assess the impact of EBCR in ≥ 70-years-old vs. younger post-AMI patients.

Methods

We retrospectively evaluated patients who underwent a supervised EBCR protocol, twice a week during 6-12 weeks. We evaluated changes in several outcomes based on pre- and post-CRP assessments.

Results

Of a total of 1607 patients, 333 (21%) were ≥ 70-years-old. After the EBCR, an overall improvement on functional capacity, daily physical activity, lipid profile, body mass index, glycated hemoglobin (HbA1c), N-terminal pro-brain natriuretic peptide (NT-pro-BNP) and C-reactive protein was observed in both younger and older patients (P < 0.05). Older patients showed a smaller benefit on the increment of daily physical activity and lipid profile improvement, but a larger reduction in NT-pro-BNP. In the multivariate analysis, only improvements on daily physical activity and HbA1c were dependent on age.

Conclusion

As their younger counterparts, older patients, significantly improved functional capacity, metabolic parameters and level of daily physical activity after EBCR.

Improvements in exercise capacity of older adults during cardiac rehabilitation

AIMS

Cardiac rehabilitation plays a vital role in secondary prevention of cardiovascular patients. Female sex and higher age, however, are associated with non-referral to cardiac rehabilitation. Improving exercise capacity during cardiac rehabilitation is essential to reduce morbidity and mortality risks. The objective of this study was to closely examine the beneficial changes in exercise capacity of older patients of both sexes during cardiac rehabilitation and to identify the most important predictors of the change in exercise capacity.

METHOD

A sample of 13,612 patients (mean age = 69.10 ± 11.8 years, 63.7% men, 19% > 80 years) was analysed. Data were prospectively assessed from 2012-2018 in six Swiss in-patient cardiovascular rehabilitation clinics. Improvement in exercise capacity measured with the six-minute walking test represents the outcome variable. Univariate and multivariate analyses, as well as the random forest method were used to estimate variable importance.

RESULTS

Mean improvement in the six-minute walking test was 113.5 ± 90.5 m (men = 118.7 ± 110.0; women = 104.4 ± 93.0, Cohen's d = 0.16). The presence of heart failure, diabetes mellitus and psychiatric diagnoses was related to reduced but nonetheless clinically relevant six-minute walking test improvement. Random forest analysis suggests that baseline exercise capacity, age, time in rehabilitation and heart failure were the most important predictors for improvement in exercise capacity. Clinically relevant improvements in exercise capacity (>45 m) were also present into old age (85 years) and for both sexes.

CONCLUSION

As indicated by these results, efforts need to be increased to refer eligible patients to structured rehabilitation programmes, irrespective of patients' age and sex.

Association Between Mobility Measured During Hospitalization and Functional Outcomes in Older Adults With Acute Myocardial Infarction in the SILVER-AMI Study

Importance

Many older survivors of acute myocardial infarction (AMI) experience functional decline, an outcome of primary importance to older adults. Mobility impairment has been proposed as a risk factor for functional decline but has not been evaluated to date in older patients hospitalized for AMI.

Objective

To examine the association of mobility impairment, measured during hospitalization, as a risk marker for functional decline among older patients with AMI.

Design, Setting, and Participants

Prospective cohort study among 94 academic and community hospitals in the United States. Participants were 2587 hospitalized patients with AMI who were 75 years or older. The study dates were January 2013 to June 2017.

Main Outcomes and Measures

Mobility was evaluated during AMI hospitalization using the Timed "Up and Go," with scores categorized as preserved mobility (≤15 seconds to complete), mild impairment (>15 to ≤25 seconds to complete), moderate impairment (>25 seconds to complete), and severe impairment (unable to complete). Self-reported function in activities of daily living (ADLs) (bathing, dressing, transferring, and walking around the home) and walking 0.4 km (one-quarter mile) was assessed at baseline and 6 months after discharge. The primary outcomes were worsening of 1 or more ADLs and loss of ability to walk 0.4 km from baseline to 6 months after discharge. The association between mobility impairment and risk of functional decline was evaluated with multivariable-adjusted logistic regression.

Results

Among 2587 hospitalized patients with AMI, the mean (SD) age was 81.4 (4.8) years, and 1462 (56.5%) were male. More than half of the cohort exhibited mobility impairment during AMI hospitalization (21.8% [564 of 2587] had mild impairment, 16.0% [414 of 2587] had moderate impairment, and 15.2% [391 of 2587] had severe impairment); 12.8% (332 of 2587) reported ADL decline, and 16.7% (431 of 2587) reported decline in 0.4-km mobility. Only 3.8% (30 of 800) of participants with preserved mobility experienced any ADL decline compared with 6.9% (39 of 564) of participants with mild impairment (adjusted odds ratio [aOR], 1.24; 95% CI, 0.74-2.09), 18.6% (77 of 414) of participants with moderate impairment (aOR, 2.67; 95% CI, 1.67-4.27), and 34.7% (136 of 391) of participants with severe impairment (aOR, 5.45; 95% CI, 3.29-9.01). Eleven percent (90 of 800) of participants with preserved mobility declined in ability to walk 0.4 km compared with 15.2% (85 of 558) of participants with mild impairment (aOR, 1.51; 95% CI, 1.04-2.20), 19.0% (78 of 411) of participants with moderate impairment (aOR, 2.03; 95% CI, 1.37-3.02), and 24.6% (95 of 386) of participants with severe impairment (aOR, 3.25; 95% CI, 2.02-5.23).

Conclusions and Relevance

This study's findings suggest that mobility impairment assessed during hospitalization may be a potent risk marker for functional decline in older survivors of AMI. These findings also suggest that brief, validated assessments of mobility should be part of the care of older hospitalized patients with AMI to identify those at risk for this important patient-centered outcome.

Clinical Practice Guideline for Cardiac Rehabilitation in Korea: Recommendations for Cardiac Rehabilitation and Secondary Prevention after Acute Coronary Syndrome

Though clinical practice guidelines (CPGs) for cardiac rehabilitation (CR) are an effective and widely used treatment method worldwide, they are as yet not widely accepted in Korea. Given that cardiovascular (CV) disease is the second leading cause of death in Korea, it is urgent that CR programs be developed. In 2008, the Government of Korea implemented CR programs at 11 university hospitals as part of its Regional Cardio-Cerebrovascular Center Project, and 3 additional medical facilities will be added in 2019. In addition, owing to the promotion of CR nationwide and the introduction of CR insurance benefits, 40 medical institutions nationwide have begun CR programs even as a growing number of medical institutions are preparing to offer CR. The purpose of this research was to develop evidence-based CPGs to support CR implementation in Korea. This study is based on an analysis of CPGs elsewhere in the world, an extensive literature search, a systematic analysis of multiple randomized control trials, and a CPG management, development, and assessment committee comprised of thirty-three authors-primarily rehabilitation specialists, cardiologists, and thoracic surgeons in 21 university hospitals and 2 general hospitals. Twelve consultants, primarily rehabilitation, sports medicine, and preventive medicine specialists, CPG experts, nurses, physical therapists, clinical nutritionists, and library and information experts participated in the research and development of these CPGs. After the draft guidelines were developed, 3 rounds of public hearings were held with staff members from relevant academic societies and stakeholders, after which the guidelines were further reviewed and modified. CR involves a more cost-effective use of healthcare resources relative to that of general treatments, and the exercise component of CR lowers CV mortality and readmission rates, regardless of the type of coronary heart disease and type and setting of CR. Individualized CR programs should be considered together with various factors, including differences in heart function and lifestyle, and doing so will boost participation and adherence with the CR program, ultimately meeting the final goals of the program, namely reducing the recurrence of myocardial infarction and mortality rates.

Never Too Old for Cardiac Rehabilitation

Prevalence of cardiovascular disease (CVD) increases with age and is endemic in the burgeoning population of older adults. Older adults with CVD are susceptible not only to high mortality but also to increased likelihood of disability, dependency, functional decline, and poor quality of life. Cardiac rehabilitation (CR) is a multidimensional and comprehensive treatment program that can potentially address many of the distinctive challenges of older adults with CVD. In this review, the wide range of potential benefits of CR for older adults with CVD is summarized.

Barriers to Outpatient Hospital-Based Cardiac Rehabilitation in Korean Patients With Acute Coronary Syndrome

Objective

To investigate factors associated with enrollment and participation in cardiac rehabilitation (CR) in Korea.

Methods

Patients admitted to four university hospitals with acute coronary syndrome between June 2014 and May 2016 were enrolled. The Cardiac Rehabilitation Barriers Scale (CRBS) made of 21-item questionnaire and divided in four subdomains was administered during admission. CRBS items used a 5-point Likert scale and ≥2.5 was considered as a barrier. Differences between CR non-attender and CR attender, or CR non-enroller and CR enroller in subscale and each items of CRBS were examined using the chi-square test.

Results

The CR participation rate in four hospitals was 31% (170 of the 552). Logistical factors (odds ratio [OR]=7.61; 95% confidence interval [CI], 4.62-12.55) and comorbidities/functional status (OR=6.60; 95% CI, 3.95-11.01) were identified as a barrier to CR enrollment in the subdomain analysis. Among patients who were enrolled (agreed to participate in CR during admission), only work/time conflict was a significant barrier to CR participation (OR=2.17; 95% CI, 1.29-3.66).

Conclusion

Diverse barriers to CR participation were identified in patients with acute coronary syndrome. Providing the tailored model for CR according to the individual patient's barrier could improve the CR utilization. Further multicenter study with large sample size including other CR indication is required.

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.

Cognitive Outcomes of Cardiovascular Surgical Procedures in the Old: An Important but Neglected Area

Older individuals can now undergo invasive cardiovascular procedures without serious concern about mortality, and the numbers and proportions of the over 65s and 85s doing so in Australia has been increasing over the last 20 years. There is overwhelming evidence linking cardiovascular conditions to late-life (65 years and over) cognitive impairment and dementia including Alzheimer's Disease, primarily due to impaired cerebrovascularisation and cascading neuropathological processes. Somewhat paradoxically, these cardiovascular interventions, carried out with the primary aim of revascularisation, are not usually associated with short- or long-term improvements in cognitive function in older adults. We discuss factors associated with cognitive outcomes post-cardiovascular surgeries in patients over 65 years of age. There are many opportunities for future research: we know almost nothing about cognitive outcomes following invasive cardiac procedures in the oldest old (85 years and over) nor how to predict the cognitive/delirium outcome using pre-surgical data, and lastly, intervention opportunities exist both pre and postoperatively that have not been tested. As our population ages with increased cardiovascular burden and rates of cardiovascular interventions and surgeries, it is critical that we understand the cognitive consequences of these procedures, who is at greatest risk, and ways to optimise cognition.

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.

Protocol for the PREHAB study-Pre-operative Rehabilitation for reduction of Hospitalization After coronary Bypass and valvular surgery: a randomised controlled trial

INTRODUCTION

Frailty is a geriatric syndrome characterised by reductions in muscle mass, strength, endurance and activity level. The frailty syndrome, prevalent in 25-50% of patients undergoing cardiac surgery, is associated with increased rates of mortality and major morbidity as well as function decline postoperatively. This trial will compare a preoperative, interdisciplinary exercise and health promotion intervention to current standard of care (StanC) for elective coronary artery bypass and valvular surgery patients for the purpose of determining if the intervention improves 3-month and 12-month clinical outcomes among a population of frail patients waiting for elective cardiac surgery.

METHODS AND ANALYSIS

This is a multicentre, randomised, open end point, controlled trial using assessor blinding and intent-to-treat analysis. Two-hundred and forty-four elective cardiac surgical patients will be recruited and randomised to receive either StanC or StanC plus an 8-week exercise and education intervention at a certified medical fitness facility. Patients will attend two weekly sessions and aerobic exercise will be prescribed at 40-60% of heart rate reserve. Data collection will occur at baseline, 1-2 weeks preoperatively, and at 3 and 12 months postoperatively. The primary outcome of the trial will be the proportion of patients requiring a hospital length of stay greater than 7 days.

POTENTIAL IMPACT OF STUDY

The healthcare team is faced with an increasingly complex older adult patient population. As such, this trial aims to provide novel evidence supporting a health intervention to ensure that frail, older adult patients thrive after undergoing cardiac surgery.

ETHICS AND DISSEMINATION

Trial results will be published in peer-reviewed journals, and presented at national and international scientific meetings. The University of Manitoba Health Research Ethics Board has approved the study protocol V.1.3, dated 11 August 2014 (H2014:208).

TRIAL REGISTRATION NUMBER

The trial has been registered on ClinicalTrials.gov, a registry and results database of privately and publicly funded clinical studies (NCT02219815).

An early intervention program for subacute physical disability related to musculoskeletal diseases in the elderly: a pilot study

To evaluate the efficacy of a program for subacute physical disability due to musculoskeletal disorders (MSD) in the elderly. We carried out a randomized controlled evaluator-blinded intervention study in a health district (October 2005 to April 2008). Subjects older than 64, starting a subacute MSD episode of physical disability-defined as moderate disability or higher in the Rosser classification-and identified by general practitioners, were randomized into standard care or an early specific program. The program was carried out by rheumatologists following detailed proceedings. Efficacy was defined as the difference between groups in the duration of episodes-time from onset until an improvement larger than a point in the Rosser classification). Hazard ratios (HR) to recovery of the program over standard care were obtained from Cox regression analyses. One hundred and twenty-three patients were included, generating 244 episodes of subacute MSD. Mean duration of episodes was 5 months; 14.5 % of them were chronically disabled throughout follow-up. The program was associated with shorter duration of episodes compared with CG analyzing just the ended ones (p = 0.004). The HR to recovery between groups did not achieve statistical differences. Nevertheless, recovery rate at 12 months and HR from those with moderate physical disability at the inclusion period (Rosser disability level 4, n = 84) were superior in the IG (HR 1.9, p = 0.03; HR 1.93; p = 0.03 respectively). An early intervention program for subacute MSD-related disability in elderly has partial efficacy; the program benefited patients with moderate physical disability and after a year of follow-up.

[Situation of acute inpatient geriatric patients. A retrospective analysis of health care processes of geriatric and non-geriatric patients with acute myocardial infarction]

BACKGROUND

Although cardiovascular diseases belong to the most frequent causes of inpatient treatment of older people the specific characteristics of geriatric patients in the acute care unit still receive marginal attention. The aim of this study was the descriptive representation of clinical health care processes of geriatric and non-geriatric patients with acute myocardial infarction.

PATIENTS AND METHODS

Using a retrospective document analysis 83 medical patient records were examined with regard to nursing, therapeutic as well as medical measures and social counseling. The classification in geriatric and non-geriatric patients was based on a predefined list of criteria.

RESULTS

In the study a total of 48 geriatric and 35 non-geriatric patients could be identified. There was a comprehensive need for support of nursing and therapeutic care, a high frequency of complications and a long length of stay as well as specifics concerning the place of discharge in geriatric patients.

CONCLUSIONS

Complex problems and special care needs of geriatric patients with acute myocardial infarction were shown. This vulnerable group of patients should be given more attention in acute care. Further investigations with a prospective character are necessary in order to detect the specific needs of geriatric patients in acute care.

Effects of a structured physical activity intervention on measures of physical performance in frail elderly patients after cardiac rehabilitation: a pilot study with 1-year follow-up

The objective of this prospective randomized controlled study was to compare the long-term effects of a structured physical activity intervention with those of aerobic exercises alone, in a cohort of elderly patients who had undergone elective cardiac surgery, and who were classified as frail at the end of rehabilitation based on their Short Physical Performance Battery (SPPB) score. At the end of rehabilitation, 140 frail elderly patients were randomly allocated either to the intervention group (IG) or to the control group (CG). CG participants received the usual aerobic exercise prescription, while IG participants were also taught additional exercises for strength, flexibility, balance and coordination. The improvement in SPPB score after 1 year was the outcome of the study. IG showed a significant improvement in SPPB score (9.0 ± 1.1 vs. 7.7 ± 1.4, p < 0.001), while no significant change was found in CG (7.7 ± 1.6 vs. 7.6 ± 1.5, p = 0.252). IG also showed a significantly higher proportion of participants who improved their SPPB score of at least 1 point (70 vs. 37%, p < 0.001). In conclusions, our structured physical activity intervention significantly improves the SPPB score in frail elderly patients who have undergone elective cardiac surgery. An intervention that improves the SPPB score might delay the occurrence of mobility disability.

[Effects of a cardiac rehabilitation programme in coronary patient according to age]

BACKGROUND

Benefits of cardiac rehabilitation (CR) are well established in coronary heart disease. The effects according to age are less known, especially in France.

AIM OF THE STUDY

Evaluation at 6 months of a CR programme in three groups of patients with different age.

PATIENTS AND METHODS

Two hundred and two coronary patients were included in the CR department in Machecoul between 2007 and 2009. They attended the CR programme and were examined at six months. Patients were divided into three groups: group 1, n=103 (<65 years), group 2, n=71 (65 to 75 years) and group 3, n=28 (>75 years). We analysed the exercise capacity (exercise stress testing and six minutes walk-test or 6MWT), two questionnaires (dietary and physical activity) and bio-clinical data.

RESULTS

Exercise capacity improved respectively by 24, 27 and 18% (P<0.004 between G2 and G3). The 6MWT improved by 19, 22 and 25% (P<0.01 between G1 and G3). At 6 months, the 6MWT remain stable, the dietary and physical activity scales improved in the three groups, the body mass index (BMI) was unchanged, HDL cholesterol increased, smoking prevalence was respectively 16, 0 and 0% and medical treatment were optimal in 90, 82 and 79% (NS).

CONCLUSION

If the impact of CR was almost similar in the three groups, a more prolonged physical training seems desirable in patients over 75 years.

Cardiac rehabilitation outcomes: impact of comorbidities and age

PURPOSE

Medical comorbidities (CM) contribute to cardiac rehabilitation (CR) underutilization. Whether individuals with coronary heart disease and an increased CM burden achieve similar benefits from CR as those with a low CM burden is unknown.

METHODS

We analyzed 794 patients with coronary heart disease completing CR from 1/96 to 4/08. Medical CM burden was assessed using a comorbidity index (CMI) previously validated in a CR population. Distance achieved on a 6-minute walk test, body mass index, and the physical and mental component scores on the Medical Outcomes Short Form 36 were measured at baseline and at CR completion. We performed multivariable linear regression to compare changes in these parameters between individuals with a low CM burden (CMI = 0) and those with a moderate (CMI = 1-2) or high (CMI > 2) CM burden by age group (<56, 56-65, and >65 years of age).

RESULTS

Mean age was 61.6 ± 10.6 years, 29% were women, 31% nonwhite; 305 individuals had a CMI = 0, 305 had a CMI = 1 to 2, and 184 had a CMI > 2. All subgroups, regardless of age or CMI, demonstrated improvements with CR on virtually all parameters measured. Among individuals younger than 56 years, those with a CMI = 0 had greater improvements in these parameters after multivariable adjustment than those with a CMI of 1 to 2 or more than 2. In contrast, in older age groups, the degree of improvement was similar regardless of CMI.

CONCLUSION

All patient groups, regardless of CM burden, benefited from CR. Medical CM burden, especially among older patients, should not discourage referral to CR.

Predicting cardiac rehabilitation attendance in a gender-tailored randomized clinical trial

PURPOSE

This study compared attendance of women participating in a motivationally enhanced, gender-tailored cardiac rehabilitation (CR) program with that of women attending a traditional outpatient CR program. We also sought to determine the significant baseline predictors of attendance of the exercise and education components of the interventions.

METHODS

Data from 252 women with CHD in the randomized clinical trial, the Women's-Only Cardiac Rehabilitation Program, were used in this study. The experimental design used 2 treatment groups: both receiving a comprehensive, 12-week, CR program, with 1 group receiving a gender-tailored, stage-of-change matched, behavioral enhancement using individualized motivational interviewing.

RESULTS

Compared with women in the traditional CR program, women in the gender-tailored program attended significantly more of the prescribed exercise (90% vs 77%) and education sessions (87% vs 56%). Group assignment accounted for about 5% of the variance in exercise attendance (F1,250 = 12.755, P < .001) and about 24% of the variance in education attendance (F1,250 = 77.942, P < .001). After controlling for group assignment, the baseline characteristics of smoking status, marital status, and anxiety accounted for about 17% of the variance in exercise attendance (F5,245 = 10.494, P < .001). Smoking status and marital status were significant baseline predictors of education attendance (F5,245 = 6.115, P < .001) after controlling for group assignment.

CONCLUSIONS

The long-standing, poor attendance of women in CR continues to be an unresolved international challenge. Gender-tailored, stage-matched, CR programs hold promise for enhancing attendance to prescribed protocols. Additional research examining the efficacy of gender-sensitive, motivationally enhanced CR for women compared with generic CR programs is warranted.

One-year adherence to exercise in elderly patients receiving postacute inpatient rehabilitation after cardiac surgery

OBJECTIVE

Promoting an active lifestyle through an appropriate physical exercise prescription is one of the major targets of cardiac rehabilitation. However, information on the effectiveness of cardiac rehabilitation in promoting lifestyle changes in elderly patients is still scant.

DESIGN

In 131 patients over the age of 65 yrs (86 men, and 45 women, mean age 75 yrs +/- 6 SD) who have attended postacute inpatient cardiac rehabilitation after cardiac surgery, we tested the 1-yr adherence to the physical exercise prescription received at the end of the cardiac rehabilitation by using a questionnaire on physical activity and the 6-min walk test.

RESULTS

All of the 36 patients who reported an active lifestyle and 49 of the 95 patients who reported a sedentary lifestyle in the year preceding the cardiac operation reported at least 1 hr/day on 5 days each week of light regular physical activity in the year after the cardiac rehabilitation. Further, the distance walked at the follow-up 6-min walk test was significantly related to the physical activity score gathered from the questionnaire.

CONCLUSIONS

Our data show that 65% of the elderly patients who have attended postacute inpatient cardiac rehabilitation after cardiac surgery are still capable of recovering or even increasing their regular physical activity and of maintaining these favorable lifestyle changes at least for 1 yr.
