Cardiac rehabilitation in the elderly: improving effectiveness

Impact of Clinical and Sociodemographic Factors on Quality of Life Following Coronary Artery Bypass Grafting: A Mixed-Methods Study

INTRODUCTION

Coronary artery bypass grafting (CABG) is an essential surgical management modality for patients with coronary artery disease. Health-related quality of life (HRQoL) has become important because of the significant decrease in the mortality rate associated with CABG. We aimed to explore the factors that affect the quality of life after CABG.

METHODS

This study used a descriptive correlational design to assess the determinants of HRQoL using the 36-item Short Form Health Survey questionnaire (SF-36). Patients who underwent CABG at King Abdulaziz University Hospital (KAUH), Jeddah, Saudi Arabia, between March 2015 and December 2021 were enrolled in this study. Overall, 275 participants were eligible for our study, of which 84 were found to be valid for analysis. Phone contacts were made directly with the patient after briefly explaining the study. Scores and clinical data were investigated using multivariable linear regression analysis.

RESULTS

Subscales of role limitations due to physical issues had the lowest mean scores, followed by vitality and general health (57.4 ± 44.7; 60.4 ± 25.6; 64.1 ± 22.6), respectively. However, social functioning (78.9 ± 29.0) and pain (75.1 ± 29.9) had the highest scores of all subscales. A history of congestive heart failure (CHF) was independently associated with lower scores for physical role limitations (p = 0.021), vitality (p = 0.001), general health (p< 0.001), and mental health (p = 0.011). Lower mental health scores were also predicted by being a widow (p = 0.030), whereas lower general health scores were predicted by being unemployed (p = 0.001) and having a peripheral vascular disease (PVD) (p = 0.043). Additionally, the development of postoperative complications was an independent predictor of lower physical functioning (p = 0.028) and vitality (p = 0.043). Regarding the number of grafts, cardiopulmonary bypass, and cross-clamp time, no significant impact was found on any of the SF-36 subscales (p> 0.05).

CONCLUSION

The postoperative decline in HRQoL was attributed to comorbidities such as CHF and PVD, postoperative complications including bleeding and wound infection, as well as unemployment and widowed status. Therefore, choosing the appropriate patients for surgery and post-discharge follow-up may enhance HRQoL.

Cardiac Rehabilitation for the Elderly: Qi Gong and Group Discussions

Background

Over the last decade several studies have shown that patients with coronary artery disease even above the age of 70 can be successfully treated with advanced medical and surgical methods. Unfortunately, rehabilitation programmes for this group are rarely offered. It is important to develop forms of rehabilitation that are adapted to the specific needs of this increasing group of elderly patients. The aim of this randomized study was to investigate whether the combination of Qi Gong and group discussions would increase physical ability for elderly patients ≥ 73 years with coronary artery disease.

Methods

A total of 95 patients (66 men and 29 women), with documented coronary artery disease, were randomized to an intervention group (n = 48) mean age 77 ± 3 (73-82) or to a control group (n = 47) mean age 78 ± 3 (73-84). The intervention groups met weekly over 3 months. The control group got usual care. Physical ability was assessed at baseline and after the intervention.

Results

Patients in the intervention group increased their self-estimated level of physical activity (P = 0.011), and their performance in the one-leg stance test for the right leg (P = 0.029), co-ordination (P = 0.021) and the box-climbing test for right leg (P = 0.035).

Conclusion

A combination of Qi Gong and group discussions appear to be a promising rehabilitation for elderly cardiac patients in terms of improving self-reported physical activity, balance and co-ordination. This could be an option for elderly patients who do not participate in the ordinary cardiac rehabilitation. Eur J Cardiovasc Prev Rehabil 12:5-11 © 2005 The European Society of Cardiology

Effects of an intervention on health behaviors of older coronary artery bypass (CAB) patients

Coronary artery bypass (CAB) patients are older increasingly more often than before. Effectiveness of cardiac rehabilitation among the elderly is not yet adequately known about. The purpose was to describe short-term (3-month), intermediate (6-month), and long-term (12-month) effects of health counseling, guidance, and adjustment education in groups on health, health behaviors, and functional abilities among older CAB patients. The study population was randomized to an intervention group (IG=49) and a control group (CG=68). Prior to CAB, intervention included one guidance and counseling group session and four sessions within 12 months following CAB. Intervention had positive effects on exercise activities, use of alcohol, and functional abilities among all participants, and on frequency of eating visible fat, fresh greens and vegetables among men. The intervention was effective with some exercise activities and functional abilities persisting for at least 1 year following CAB. Similar interventions may be arranged for older people. Health care professionals need to guide and encourage older people in their efforts to participate in them.

Risk factors of Hong Kong Chinese patients with coronary heart disease

AIMS AND OBJECTIVES

The aims of the study were to describe the level of modifiable coronary risk factors and to explore the relationships among these risk factors in patients with coronary heart disease.

BACKGROUND

Appropriate patient education and therapies for coronary risk reduction will prevent recurrent cardiac events and progression of coronary heart disease. Therefore, having knowledge of the risk profile of these patients is essential so that appropriate contents and focus of patient educations can be developed.

METHODS

Coronary heart disease patients admitted for cardiac catheterization at the two studied hospitals in Hong Kong were recruited for this study. Demographic date and risk factors of blood pressure, smoking status, body mass index, total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol and exercise level were collected from subjects as well as from medical records for analysis.

RESULTS

The body mass index was significantly different among non-smoker, ex-smoker and smoker (p = 0.027). Non-smokers had the highest body mass index but smokers had the lowest body mass index among the three groups in this study. Physical inactivity, overweight and hypercholesterolaemia were the risk factors seen in about 50% of the studied subjects. Body mass index correlated positively with systolic blood pressure but negatively correlated with high-density lipoprotein cholesterol and hour of exercise.

CONCLUSIONS

Heavier subjects had a higher systolic blood pressure but a lower level of high-density lipoprotein cholesterol. Heavier subjects also exercised less. The study results provided additional information on the database of the risk profile among Hong Kong cardiac patients.

RELEVANCE TO CLINICAL PRACTICE

Hypertension, obesity, physical inactivity, abnormal serum lipid levels and smoking are the modifiable risk factors for coronary heart diseases. As physical inactivity, overweight and hypercholesterolaemia were found in half of the studied subjects, the importance of risk factors control should be addressed to this group of patients. Nurses should be aware of their educator role to provide appropriate education to coronary heart disease patients with the focus on reducing and controlling of cardiac risk factors, which has been shown to be effective in reducing the progress of disease.

Cardiac rehabilitation in the elderly: patient selection and outcomes

In Western countries, the aging and improving survival of patients with coronary heart disease are responsible for an increasing number of older adults (65 years of age and older) who are eligible for cardiac rehabilitation. The elderly with coronary heart disease represent a special population with changes induced by aging and lifestyle, comorbidity, cognitive dysfunction, and high risk of disability. Although the elderly account for the majority of cardiac admissions and procedures, studies on cardiac rehabilitation have traditionally focused on younger patients. In aged experimental animals, there is evidence that exercise training is able to improve hemodynamic parameters and biologic markers. Moreover, in older patients, exercise improves functional capacity and reduces myocardial work, similar to that seen in younger patients. As for younger patients, cardiac rehabilitation requires a multidisciplinary approach, including comprehensive assessment, treatment of risk factors and comorbidity, and psychosocial assessment. Cardiac rehabilitation is safe and helpful for elderly coronary patients. Physicians must be encouraged to prescribe cardiac rehabilitation programs for the elderly following major coronary events and coronary revascularization procedures.

Re-engineering cardiac rehabilitation programmes: considering the patient's point of view

AIMS

The aim of this paper is to report a study to describe how cardiac patients experience the first 3 months following a cardiac event requiring hospitalization, identify differences between the needs expressed by patients and the support they received during their recuperation and produce a preliminary model for the development of cardiac rehabilitation programmes, taking into account the patient perspective.

BACKGROUND

Although cardiac rehabilitation should be standard care for patients with cardiovascular disease, less than 20% begin and maintain a rehabilitation programme. Cited barriers include inadequate rehabilitation services, sub-optimal referral, low participation rates of women and older adults and travel considerations. The literature suggests that programmes better adjusted to patient needs could increase attendance, but little research has considered this perspective.

METHODS

Focus groups were conducted with a purposefully selected sample of 20 men and women who had been hospitalized for myocardial infarction, angina or percutaneous angioplasty. Data were analysed using qualitative content analysis.

FINDINGS

A gap exists between what traditional rehabilitation programmes offer and patients' expressed needs during the recuperating process after hospitalization for a cardiac event. In our study, participants focused on stress management rather than on modifying health habits. Support groups were viewed as beneficial and, according to patients, accepting their condition, knowing their limits and better continuity of care would also help reduce stress. Based on the findings, we devised a model as the basis for developing cardiac rehabilitation programmes.

CONCLUSION

Cardiac rehabilitation programmes need to shift their focus of attention from promoting healthier behaviours to responding to participants' perceived needs, alongside risk factor reduction.

Improving uptake and adherence in cardiac rehabilitation: literature review

AIMS

This paper presents a comprehensive systematic review of literature carried out to identify studies of interventions to improve uptake, adherence and professional compliance in cardiac rehabilitation.

BACKGROUND

Guidelines recommend that cardiac rehabilitation should be offered to patients following acute myocardial infarction and revascularization. Uptake and adherence are low, particularly in women, older people, and socially deprived and ethnic minority patients. Although patient, service and professional barriers to rehabilitation uptake have been described, no attempt has been made to evaluate systematically interventions aimed at improving uptake and adherence in cardiac rehabilitation.

METHODS

A comprehensive search strategy identified studies of cardiac rehabilitation, using the terms uptake, adherence and compliance. The search included grey literature, hand searching of specialist journals and conference abstracts. No language restriction was applied. Studies were summarized in three qualitative overviews and assessed by quality of evidence.

RESULTS

From 3261 publications identified, 957 were acquired on the basis of title or abstract. Few studies were of sufficient quality to make specific recommendations. Six, 12 and five studies, respectively, provided adequate information on methods to improve uptake, adherence or professional compliance. A minority of studies were randomized controlled trials. Studies of motivational and self-management strategies and use of lay volunteers showed some promise in improving rehabilitation uptake or lifestyle change. Nurse-led coordination of care after hospital discharge may have a role in improving rehabilitation uptake. Limited information was provided on resource implications, and there was a lack of studies with under-represented groups. The literature contained numerous suggested interventions which merit evaluation in appropriately designed studies.

CONCLUSIONS

Little research has been reported evaluating interventions to improve uptake, adherence and professional compliance in cardiac rehabilitation. A wide range of possible interventions was identified and further evaluations of methods are indicated.

Informed Consent: A Process to Facilitate Older Adults' Participation in Research

Trust is the foundation of the informed consent process. According to Kass et al., Yet only through vigilance and humility will we, as investigators, be able to live up to the trust that is placed in us; and only if that trust is deserved can the research enterprise survive (1996, p. 28). Therefore, further research should examine the effect of the informed consent process in limiting older adults' participation. Only by re-evaluating the first point of contact, implementing creative strategies to overcome barriers to the informed consent process, and validating these strategies through research will nurses facilitate the inclusion of older adults in research.

The illness experiences of patients after a first time myocardial infarction

The purpose of this study was to investigate illness experiences of patients after a first myocardial infarction (MI), focusing on life situation and the recovery process over time. Thirty patients were interviewed within the first 3 days of hospitalisation, and again 17 weeks after discharge. The interviews were tape-recorded verbatim and the transcriptions were analysed and categorised using qualitative content analysis. The main category was Uncertainty of the life situation that was combined with and articulated the superior theme in both interviews. Analyses revealed uncertainty focused on problems related to: treatment-seeking behaviour; existential threat; preventing another coronary and need for knowledge and support, which the patients considered important for their case and future life. The findings are fundamental for the health care when education and counselling are planned and challenge health care personnel to listen to MI-patients' own experiences.

Aerobic exercise and the post myocardial infarction patient: a review of the literature

Meta analyses of randomized controlled tests of cardiac rehabilitation after myocardial infarction demonstrate that regular exercise reduces the risk of overall mortality and cardiovascular mortality. In patients with established coronary artery disease, exercise is associated with improved activity tolerance, modification of risk factors, and improvement in quality of life. Randomized controlled tests demonstrate that whereas older patients after coronary events are substantially less fit than younger patients, they obtain a similar relative improvement of aerobic capacity with a graded conditioning program. However, older adults are enrolled in such programs at a lower rate than other age groups. Despite similar clinical profiles to men, women are less likely to participate in exercise rehabilitation. In this article we discuss the principles of program development, guidelines for monitoring of patients, and facilitation of exercise programs in the Australian context.

A conceptual map for studying long-term exercise adherence in a cardiac population

The failure of people with coronary heart disease to adhere to prescribed programs of long-term exercise is a growing concern among healthcare professionals. The problem is attributed partly to not correctly identifying the specific exercise adherence behavior desired. There is a need in cardiac rehabilitation for different theoretical and practical approaches to the study of patient adherence to short-term and long-term exercise prescriptions. This article is a review of behavioral and cognitive models used to promote exercise in cardiac rehabilitation programs. Concepts are borrowed from these models to design a conceptual map intended to identify variables and relationships associated with exercise adherence behaviors. In this article, the Coronary Artery Disease Exercise Map (CADEM), an evolving conceptual map, addresses exercise behavior within a coronary population. However, this map may also be applied to people who have other chronic conditions. It is believed that the CADEM will provide researchers and healthcare providers with a framework with which to understand, promote, and evaluate adherence to exercise regimes within the rehabilitation population.

Effectiveness of home-based cardiac rehabilitation for special needs patients

BACKGROUND

The benefits of cardiac rehabilitation programmes have been well documented including reductions in mortality, improved physical performance, and improved quality of life. However, a large number of special needs patients often fail to access these programmes. Of particular concern are elderly patients with chronic illness and disability.

AIMS

To evaluate the effectiveness of a home-based cardiac rehabilitation programme in improving health outcomes and rehabilitation access for special-needs patients.

DESIGN

Using a one-group pre and post-test quasi-experimental design 40 elderly patients recently discharged from hospital following a cardiac event completed the Short Form Health Survey, the Angina Quiz, and the Exercise Assessment Questionnaire prior to undertaking home-based rehabilitation. The rehabilitation programme consisted of four community nursing contacts over a 9-week period primarily aimed at individual patient education and carer support.

ANALYSIS

Descriptive statistics provided analysis for demographic data. Repeated measures multivariate analysis of variance (manova) were computed to examine changes in health-state and practices.

RESULTS

Significant positive changes were found for measures of quality of life, knowledge of angina, and exercise tolerance. Additionally, the higher levels of participation and completion by older women was encouraging. Development of carer competence through an improved knowledge base and nursing support was also evident.

LIMITATIONS

While theoretically defensible positive outcomes were found these results need to be replicated in a larger study. Similarly, the limitations imposed by a single group pretest, post-test design suggest that claims of generalizability need to be limited to the specific variables measured in this study.

CONCLUSION

The study demonstrated medium term positive health outcomes. These positive findings suggest that home-based rehabilitation using larger samples of older patients with comorbidities, and using randomized comparative group designs, may be a fruitful area in future research.

I want to know: exploring how older women acquire health knowledge after a myocardial infarction

The purpose of this descriptive naturalistic study was to: (a) explore how older women not participating in outpatient cardiac rehabilitation (CR) acquire health knowledge regarding secondary prevention measures after a myocardial infarction (MI), and (b) describe women's perceived barriers to acquiring this knowledge. Women (N = 15), ages 66-88, participated in semi-structured in-depth interviews. Data analysis resulted in four global categories: (a) previous learning, (b) self knowledge, (c) actively seeking knowledge from others, and (d) information provided by others. Barriers to acquiring health knowledge after MI without the support of outpatient CR were also identified.

Quality of life 12 months after coronary artery bypass graft surgery

OBJECTIVE

The primary purpose of this study was to assess the relationship between preoperative risk factors, postoperative chronic pain, sleep, and gender on perceptions of quality of life (QoL) in a sample of 123 coronary artery bypass graft (CABG) surgery patients 12 months after surgery. A secondary purpose was to determine whether there is concordance between spousal and patient reporting of QoL after CABG surgery.

DESIGN

A cross-sectional comparative study.

SETTING

The study setting included patients living in the community, who had had CABG surgery 12 months earlier at The Alfred hospital, a major metropolitan public acute care center, in Melbourne, Australia.

PARTICIPANTS

Study participants were 123 adult patients (mean age = 64 years) who had undergone CABG surgery and had participated in a recent clinical trial. These patients were followed up to 12 months. The patient's spouse or next of kin (NoK) was asked questions about their perception of change in the patient's QoL.

INSTRUMENTS

Results were assessed using The Medical Outcome Study Short Form-36 (SF-36) questionnaire and additional questions given at 12 months after CABG surgery. The Cleveland Clinic Clinical Severity Score (CSS) was used preoperatively as a tool to predict QoL outcome.

RESULTS

Significant improvements in QoL, as measured by the SF-36, were seen in physical functioning (P <.0001), bodily pain (P =.024), social functioning (P =.011), and role limitations resulting from emotional status (P =.003). Other significant associations (P =.002) were found between poor QoL and patients who reported severe pain or poor quality sleep. Low-risk patients, as identified by the preoperative CSS, were more likely to have improved QoL at 12 months. Alteration in QoL was reported equally by patients and their spouses or NoK. Short-term memory impairment was reported by 41% of spouses or NoK.

CONCLUSIONS

CABG surgery results in improved QoL for the majority of patients with extensive coronary artery disease. Nevertheless, some patients continue to have severe pain, sleep disturbances, and altered relationship with their spouse or NoK 12 months after surgery.

Functional status outcomes of patients with a coronary artery bypass graft over time

OBJECTIVE

To examine functional status outcomes among patients with a coronary artery bypass graft (CABG) over time (ie, at baseline; 3 months, 6 months, and 12 months after surgery) and the impact of selected patient characteristics (ie, age, sex, comorbidities, and cardiac rehabilitation participation) on functional outcomes.

DESIGN

A prospective, repeated-measures design was used to examine functional status in patients with a CABG over time.

SETTING

A midwestern community hospital and regional cardiac referral center was the setting for enrolling patients with a CABG.

OUTCOME MEASURES

Functional status outcomes were measured by using the Medical Outcomes Study (MOS) Short Form 36 (SF-36) and Modified 7-Day Activity instruments.

METHODS

Baseline data were obtained by patient interview in the hospital setting after CABG surgery. At 3 months, 6 months, and 12 months after surgery, telephone interviews were conducted to administer research instruments.

RESULTS

Baseline scores on 7 of the 8 subscales of the MOS SF-36 were significantly lower than at 3 months, 6 months, or 12 months after surgery. Role-emotional functioning baseline scores were not significantly lower than 3-month scores; however, baseline scores were significantly lower than 6-month and 12-month scores. Three-month subscale scores were also significantly lower than 6-month or 12-month scores except for the subscales measuring social and general health functioning. Functional status as measured by the Modified 7-Day Activity tool did not demonstrate any significant differences between 3-month, 6-month, or 12-month activity levels. There were no significant differences by age group on any of the 8 subscales of the MOS SF-36 instrument. Women and subjects with more than 1 comorbidity had a significantly lower preoperative level of physical functioning. Cardiac rehabilitation participants had lower preoperative scores on role-emotional functioning than subjects who were not in rehabilitation.

CONCLUSION

Findings from this study can assist nurses and other health care workers to gain a perspective of the recovery and rehabilitation trajectory of patients with a CABG. The results of the study provide a basis for determining areas of functional limitations during recovery from CABG surgery. Study results can also be the foundation for evaluating outcomes of patients with a CABG when specific interventions (eg, pain management, psychosocial support, physical strengthening, fatigue management) are implemented during hospitalization, home recovery, and rehabilitation to target optimal psychosocial and physiologic functioning of patients with a CABG.
