Short-term patient-reported outcomes after different exercise-based cardiac rehabilitation programmes

Barriers and Facilitators to Delivering Inpatient Cardiac Rehabilitation: A Scoping Review

Objective

The purpose of this scoping review was to summarize the literature on barriers and facilitators that influence the provision and uptake of inpatient cardiac rehabilitation (ICR).

Methods

A literature search was conducted using PsycINFO, MEDLINE, EMBASE, CINAHL and AgeLine. Studies were included if they were published in English after the year 2000 and focused on adults who were receiving some form of ICR (eg, exercise counselling and training, education for heart-healthy living). For studies meeting inclusion criteria, descriptive data on authors, year, study design, and intervention type were extracted.

Results

The literature search resulted in a total of 44,331 publications, of which 229 studies met inclusion criteria. ICR programs vary drastically and often focus on promoting physical exercises and patient education. Barriers and facilitators were categorized through patient, provider and system level factors. Individual characteristics and provider knowledge and efficacy were categorized as both barriers and facilitators to ICR delivery and uptake. Team functioning, lack of resources, program coordination, and inconsistencies in evaluation acted as key barriers to ICR delivery and uptake. Key facilitators that influence ICR implementation and engagement include accreditation and professional associations and patient and family-centred practices.

Conclusion

ICR programs can be highly effective at improving health outcomes for those living with CVDs. Our review identified several patient, provider, and system-level considerations that act as barriers and facilitators to ICR delivery and uptake. Future research should explore how to encourage health promotion knowledge amongst ICR staff and patients.

Average and Interindividual Effects to a Comprehensive Cardiovascular Rehabilitation Program

Background: To describe the average effects and the interindividual variability after a comprehensive outpatient cardiovascular rehabilitation (CCR) program using concurrent exercise training prescribed according to cardiovascular risk stratification on cardiorespiratory fitness (CRF), anthropometric/body composition, quality of life and emotional health in patients of four cardiovascular disease profiles. Methods: CRF, anthropometric/body composition, quality of life, and emotional health were measured before and after a CCR and analyzed in heart valve surgery (HVS), heart failure with reduced ejection fraction (HFrEF), post-acute myocardial infarction (post-AMI), and in coronary artery disease (CAD) patients. Twenty, twenty-four, and thirty-two exercise sessions were prescribed according to mild, moderate, and severe baseline cardiovascular risk, respectively. In addition to concurrent exercise training, nutritional counseling, psychological support, and lifestyle education programs were performed. Results: The main outcomes by delta changes comparisons (Δ) revealed no significant differences at anthropometric/body composition as ΔBody fat decreases (HVS Δ−1.1, HFrEF Δ−1.0, post-AMI Δ−1.4, CAD Δ−1.2 kg) and ΔSkeletal muscle mass increases (HVS Δ+1.4, HFrEF Δ+0.8, post-AMI Δ+0.9, CAD Δ+0.9 kg), and CRF performance as ΔVO2peak increases (HVS Δ+4.3, HFrEF Δ+4.8, post-AMI Δ+4.1, CAD Δ+5.1 mL/kg/min) outcomes among HVS, HFrEF, post-AMI, and CAD (p > 0.05). Secondary outcomes showed significant pre-post delta changes in METs (HVS Δ+1.8, HFrEF Δ+0.7, post-AMI Δ+1.4, CAD Δ+1.4), and maximal O2pulse (HVS Δ+3.1, post-AMI Δ+2.1, CAD Δ+1.9). In addition, quality of life had a significant improvement in physical functioning (HVS Δ+17.0, HFrEF Δ+12.1, post-AMI Δ+9.8, CAD Δ+11.2), physical role (HVS Δ+28.4, HFrEF Δ+26.8, post-AMI Δ+25.6, CAD Δ+25.3), vitality (HVS Δ+18.4, HFrEF Δ+14.3, post-AMI Δ+14.2, CAD Δ+10.6) and social functioning (HVS Δ+20.4, HFrEF Δ+25.3, post-AMI Δ+20.4, CAD Δ+14.8) in all cardiovascular disease. For anxiety (HVS Δ−3.6, HFrEF Δ−2.3, post-AMI Δ−3.0, CAD Δ−3.1) and depression (HVS Δ−2.8, HFrEF Δ−3.4, post-AMI Δ−3.2, CAD Δ−2.3) significant changes were also observed. Conclusions: A CCR program that prescribes the number of exercise sessions using a cardiovascular risk stratification improves CRF, QoL, and emotional health, and the average results show a wide interindividual variability (~25% of non-responders) in this sample of four CVD profile of patients.

Depression and anxiety in cardiac rehabilitation: differential associations with changes in exercise capacity and quality of life

BACKGROUND

Cardiac rehabilitation (CR) has been successful in improving exercise capacity (EC) and quality of life (QoL). However, depression and anxiety are highly prevalent among cardiac patients and might represent risk factors for rehabilitation outcomes. The aim of this study was to investigate the role of depression and anxiety as possible independent risk factors for CR outcomes.

METHODS

The study applied a pre-post-design. The sample comprised N = 3'434 cardiac disease patients taking part in a Swiss inpatient CR center. Variables measured at the beginning (T1) and end of rehabilitation (T2) included depression and anxiety (HADS), EC, and QoL (MacNew). A path analysis was conducted.

RESULTS

Depression at T1 had a significant negative relationship with improvements in EC and in all aspects of QoL during rehabilitation. Anxiety at T1 was positively related to improvements in EC and in emotional and physical QoL. Improvements in depression during CR were positively related with improvements in all outcomes. Improvements in anxiety showed no significant association with the outcomes.

CONCLUSION

Depression and anxiety should be screened for during CR. Depression should be treated due to the negative association found with rehabilitation outcomes. Underlying mechanisms of the positive association of anxiety with rehabilitation outcomes need further investigation.

Effect of Different Endurance Training Protocols During Cardiac Rehabilitation on Quality of Life

BACKGROUND

This study aimed to assess the effect of different types of endurance training during outpatient cardiac rehabilitation on patients' health-related quality of life (HRQL).

METHODS

The MacNew Heart Disease HRQL questionnaire and the Hospital Anxiety and Depression Scale were used to assess changes in HRQL in 66 patients before and after 6 weeks of cardiac rehabilitation. Patients were randomized to 1 of 3 types of supervised endurance training: continuous endurance training, high-intensity interval training, and pyramid training. Two-way analysis of variance for repeated measure and chi-square test were used to analyze changes before and after rehabilitation.

RESULTS

Attendance rate during the 6 weeks of exercise training was 99.2%. Physical work capacity increased from 136.1 to 165.5 watts (+22.9%; P < .001), and there were no statistical differences between training protocols. Fully completed questionnaires at both time points were available in 46 patients (73.9%; 61.3±11.6 years, 34 males, 12 females). Regardless of the type of supervised endurance training, there was significant improvement during rehabilitation in each of the categories of the MacNew questionnaire (ie, emotion, physical, social, global; all P < .05) and the Hospital Anxiety and Depression Scale (anxiety: P = .05; depression: P = .032), without significant differences between protocols.

CONCLUSIONS

All 3 types of endurance training led to significant and well comparable increases in physical work capacity, which was associated with an increase in HRQL independent of the type of training. Our findings support further individualization of training regimes, which could possibly lead to better compliance during life-long home-based exercise training.

Association Between Depressive Symptoms and Exercise Capacity in Patients With Heart Disease: A META-ANALYSIS

PURPOSE

Depression and reduced exercise capacity are risk factors for poor prognosis in patients with heart disease, but the relationship between the 2 is unclear. We assessed the relationship between depressive symptoms and exercise capacity in patients with heart disease.

METHODS

PubMed, Cochrane Library, Google Scholar, and ProQuest databases were browsed for English-language studies published from January 2000 to September 2013. Studies including adult patients with coronary artery disease, heart failure, congenital heart disease, and implantable cardioverter defibrillator, reporting correlation between a depression scale and exercise capacity ((Equation is included in full-text article.)O2peak, peak watts, estimated metabolic equivalents, and incremental shuttle walk test distance), as well as studies from which such a correlation could be calculated and provided by the authors, were included. Correlation coefficients (CCs) were converted to Fischer z values, and the analysis was performed using a random-effects model. Then, summary effects and 95% CIs were converted back to CCs.

RESULTS

Fifty-nine studies (25 733 participants) were included. Depressive symptoms were inversely correlated to exercise capacity (CC = -0.15; 95% CI, -0.17 to -0.12). Heterogeneity was significant (I = 64%; P < .001). There was no evidence of publication bias (Fail-safe N = 4681; Egger test: P = .06; Kendall test: P = .29).

CONCLUSIONS

Patients with heart disease and elevated depressive symptoms may tend to have reduced exercise capacity, and vice versa. This finding has clinical and prognostic implications. It also encourages research on the effects of improving depression on exercise capacity, and vice versa. The effects of potential moderators need to be explored.

Feeling supported and abandoned: mixed messages from attendance at a rural community cardiac rehabilitation program in Australia

PURPOSE

In 2010, the Healthy Heart (HH) community-based cardiac rehabilitation program was offered at Latrobe Community Health Service in rural Victoria, Australia. The 8-week program, based on National Heart Foundation guidelines, consisted of exercise sessions; health education on diet, stress, and smoking cessation; and behavioral change strategies. Participants were also informed about local community exercise opportunities. A program evaluation was conducted in 2011 to assess whether the content of the program was meeting the needs of participants and to identify what suggestions they had for improvement.

METHODS

Eighteen patients had completed the HH program in 2010. Eight of these participants, 7 men and 1 woman, volunteered to take part in a focus group. Conventional content analysis was used to identify and group the common themes that emerged from the focus group discussions.

RESULTS

Three themes were identified that reflected the participant experiences of attending the HH program. The first, "recovering confidence," described participant responses to the content of the sessions. The second, "putting it into practice," referred to their comments about taking responsibility for making lifestyle changes. The third, "feeling abandoned," emerged from the reported difficulty participants expressed about maintaining motivation for change after program completion.

CONCLUSION

Participants rated the HH program as very successful by objective measures. However, they reported struggling to maintain self-management strategies postprogram. There is clearly a need to develop strategies that support cardiac rehabilitation participants over the longer-term.

Impact of the Healthy Eating and Exercise Lifestyle Programme on depressive symptoms in overweight people with heart disease and diabetes

BACKGROUND

The Healthy Eating and Exercise Lifestyle Program (HEELP) is a secondary risk factor intervention programme for people with heart disease and/or type 2 diabetes, which has proven benefits for weight loss and exercise. This secondary analysis evaluated the effects of HEELP on achieving recommended levels of exercise and the prevalence of depressive symptoms, and whether meeting exercise recommendations had an independent effect on depressive symptoms.

DESIGN

A randomized parallel controlled trial of patients (n = 147) with body mass index 27-39 kg/m(2) were recruited from cardiac rehabilitation and diabetes education programmes.

METHODS

HEELP participants received a 16-week group-based lifestyle intervention of twice-weekly supervised exercise and five information sessions; the control group received usual care. At 16 weeks, achievement of recommended levels of exercise (≥ 5 days/week, moderate or higher intensity, and total duration of ≥ 150 minutes/week) and depressive symptoms (Hospital Anxiety and Depression Scale) were assessed.

RESULTS

More HEELP participants met the recommendations for exercise frequency (71 vs. 50%, p = 0.036), intensity (76 vs. 60%, p = 0.05), and total duration (65 vs. 43%, p = 0.047). The prevalence of depressive symptoms in HEELP was half that of the control group (17 vs. 34%; OR 0.397, 95% CI 0.18-0.86). Participants who met recommendations for total duration of exercise were less likely to report depressive symptoms (OR 0.29, 95% CI 0.112-0.717) after adjusting for treatment group and weight change.

CONCLUSIONS

A group-based lifestyle intervention improves exercise and reduces depressive symptoms despite multiple risk factors.

Cardiac rehabilitation may not provided a quality of life benefit in coronary artery disease patients

Background

Improvements in patient-reported health-related quality of life (HRQoL) are important goals of cardiac rehabilitation (CR). In patients undergoing coronary angiography for angina and with documented coronary artery disease (CAD), the present study compared HRQoL over 6 months in CR participants and non-participants. Clinical predictors of CR participants were also assessed.

Methods

A total of 221 consecutive patients undergoing angiography for angina with documented CAD and who were eligible for a CR program were recruited. CR participants were enrolled in a six-week Phase II outpatient CR course (31%, n = 68) within 2 months following angiography and the non-participants were included as a control. At baseline (angiography), one and six months post angiography, clinical and HRQoL data were obtained including the Short Form-36 (SF-36) and the Seattle Angina Questionnaire (SAQ). The response rate for the HRQoL assessment was 68% (n = 150). Cross sectional comparisons were age-adjusted and performed using logistic or linear regression as appropriate. Longitudinal changes in HRQoL were assessed using least squares regression. Finally, a multiple logistic regression was fitted with CR participant as the final outcome.

Results

At angiography, the CR non-participants were older, and age-adjusted analyses revealed poorer physical (angina limitation: 54 ± 25 versus 64 ± 22, p <0.05) and mental HRQoL (significant psycho-social distress: 62%, n = 95 versus 47%, n = 32, p <0.05) compared to the CR participants. In addition, the CR participants were more likely to have undergone angiography for myocardial infarction (OR = 2.8, 95% CI 1.5-5.3, p = 0.001). By six months, all patients showed an improvement in HRQoL indices, however the rate of improvement did not differ between the controls and CR participants.

Conclusion

Following angiography, CAD patients reported improvements in both generic and disease-specific HRQoL, however CR participation did not influence this outcome. This may be explained by biases in CR enrollment, whereby acute patients, who may be less limited in HRQoL compared to stable, chronic patients, are targeted for CR participation. Further investigation is required so CR programs maximize the quality of life benefits to all potential CR patients.

A comparison of psychosocial risk factors between 3 groups of cardiovascular disease patients referred for outpatient cardiac rehabilitation

PURPOSE

Few studies have examined psychosocial risk factors for cardiovascular disease (CVD) between diagnostic groups of CVD patients. We compared levels of depression, anxiety, hostility, exhaustion, positive affect, and social support, and the prevalence of type D personality between patient groups with a primary diagnosis of coronary heart disease (CHD), chronic heart failure (CHF), or peripheral arterial disease (PAD).

METHODS

We examined 548 CHD patients, 105 CHF patients, and 79 PAD patients who completed the Hospital Anxiety and Depression Scale, the cynical hostility subscale of the Minnesota Multiphasic Personality Inventory-2, the short form of the Maastricht Vital Exhaustion Questionnaire, the type D personality questionnaire, the positive mood scale of the Global Mood Scale, and the Enhancing Recovery in CHD Social Support Inventory, all in the first week of cardiac rehabilitation. Group differences in psychosocial factors were adjusted for sociodemographic factors, previous myocardial infarction, traditional cardiovascular risk factors, and medications.

RESULTS

Relative to patients with PAD, those with CHD and those with CHF both showed greater exhaustion (P ≤ .001) and lower positive affect (P ≤ .03). The effect sizes of these differences were clinically relevant (Cohen's d between 0.32 and 0.49). There were no significant differences in psychosocial risk factors between CHD and CHF patients.

CONCLUSIONS

The profile of psychosocial risk factors for CVD revealed clinically relevant variability between different diagnostic groups of CVD patients. The findings imply that patients with distinct cardiac diagnosis might additionally benefit from comprehensive cardiac rehabilitation if the program includes psychosocial risk factor-specific interventions.

Prevalence of Chest Pain, Depression, Somatization, Anxiety, Global Distress, and Substance Use among Cardiac and Pulmonary Rehabilitation Patients

Psychosocial factors of cardiovascular disease receive a preponderance of attention. Little attention is paid to psychosocial factors of pulmonary disease. This paper sought to describe psychosocial characteristics and to identify differences between cardiac and pulmonary patients entering a phase II rehabilitation program. Parametric and nonparametric analyses were conducted to examine scores on the Brief Symptom Inventory-18 (BSI-18) and the CAGE-D, administered at entry as standard clinical care. Participants were 163 cardiac and 63 pulmonary patients. Scores on the BSI-18 “chest pain” item indicated that more cardiac patients report chest pain than pulmonary patients. Among all subjects, chest pain ratings were positively related to anxiety, depression, and global distress. There were equivocal proportions of anxiety and somatization in patient groups. Pulmonary patients were more likely to endorse clinically significant levels of depression and global psychological distress than cardiac patients. Cardiac patients were significantly more likely to screen positively on the CAGE-D than pulmonary patients. Findings show a relationship between symptoms of chest pain and psychological distress. Despite equivalent proportions of anxiety and somatization between groups, a greater proportion of pulmonary patients reported symptoms of depression and global psychological distress, while more cardiac patients reported chest pain. Further research is needed to examine this paradigm.

The MacNew Heart Disease Health-Related Quality of Life Questionnaire in patients with angina and patients with ischemic heart failure

OBJECTIVE

Patient-reported outcomes including health-related quality of life are important in clinical care and research studies. The MacNew Heart Disease Health-Related Quality Of Life Questionnaire has been validated in English-speaking patients with myocardial infarction. The aim of this study was to validate the MacNew in English-speaking patients with angina or ischemic heart failure.

METHODS

Canadian and American patients with angina or ischemic heart failure completed the MacNew, the Short Form-36 Health Survey, and the Hospital Anxiety and Depression Scale.

RESULTS

We administered questionnaires to 276 patients with angina (mean age, 65.9 years) and 155 patients with ischemic heart failure (mean age, 70.3 years). The mean ± SD MacNew global score in patients with ischemic heart failure (5.1 ± 1.2) was statistically (P < 0.001), but not clinically, poorer than in patients with angina (5.3 ± 1.1). The three-factor measurement model explained 46.1% of the observed variance in the MacNew in patients with angina and 46.5% in patients with ischemic heart failure. Internal consistency was ≥0.90, and test-retest reliability was ≥0.70 for each MacNew scale and the a priori convergent and discriminative validity hypotheses were confirmed in both diagnoses. The MacNew was highly accepted by patients with little respondent or administrative burden.

CONCLUSIONS

The English version of the MacNew is reliable and valid in patients with angina or ischemic heart failure. This permits health-related quality of life outcome comparisons in patients with angina, ischemic heart failure, and myocardial infarction with the MacNew and provides a better understanding of the full range of health-related quality of life outcomes.

The effect of regular physical activity on the left ventricle systolic function in patients with chronic coronary artery disease

The purpose of this study was to assess the influence of aerobic training on the left ventricular (LV) systolic function. Thirty patients with stable coronary artery disease, who had participated in the conducted 3-month physical training, were retrospectively divided into 2 cohorts. While patients in the cohort I (n=14) had continued training individually for 12 months, patients in the cohort II (n=16) had stopped training after finishing the conducted program. Rest and stress dobutamine/atropine echocardiography was performed in all patients before the training program and 1 year later. The peak systolic velocities of mitral annulus (Sa) were assessed by tissue Doppler imaging for individual LV walls. In addition, to determine global LV systolic longitudinal function, the four-site mean systolic velocity was calculated (Sa glob). According to the blood supply, left ventricular walls were divided into 5 groups: A- walls supplied by nonstenotic artery; B- walls supplied by coronary artery with stenosis ≤50 %; C- walls supplied by coronary artery with stenosis 51-70 %; D- walls with stenosis of supplying artery 71-99 %; and E- walls with totally occluded supplying artery. In global systolic function, the follow-up values of Sa glob in cohort I were improved by 0.23±0.36 as compared with baseline values at rest, and by 1.26±0.65 cm/s at the maximal load, while the values of Sa glob in cohort II were diminished by 0.53±0.22 (p=NS), and by 1.25±0.45 cm/s (p<0.05), respectively. Concerning the resting regional function, the only significant difference between cohorts in follow-up changes was found in walls E: 0.37±0.60 versus -1.76±0.40 cm/s (p<0.05). At the maximal load, the significant difference was found only in walls A (0.16±0.84 versus -2.67±0.87 cm/s; p<0.05). Patients with regular 12-month physical activity improved their global left ventricle systolic function mainly due to improvement of contractility in walls supplied by a totally occluded coronary artery.

Short-term effects of a multi-disciplinary cardiac rehabilitation programme on psychological well-being, exercise capacity and weight in a sample of obese in-patients with coronary heart disease: a practice-level study

Given that many patients referred to cardiac rehabilitation (CR) are obese, diet therapy, exercise training, nutritional and psychological counselling for both obesity and psychological distress should be included as important components in all CR programmes. In this practice-level, observational study we evaluated the short-term within-group effects of a four-week multi-factorial inpatient CR programme specifically addressed to weight loss, fitness improvement and psychological health increase on 176 obese in-patients with coronary heart disease (CHD). Outcome measures were exercise capacity measured with estimated metabolic equivalents (METs), body mass index (BMI) and psychological well-being (PGWBI). Results show statistically significant improvements in all the PGWBI sub-scales and total score, except in general health (p = 0.393). No moderation effects were found for BMI class, age, diabetes and ejection fraction (EF). METs significantly increased by 30.3% (p < 0.001) and BMI decreased by 1.37 points (p < 0.001). Significant correlations were found between BMI and weight reductions with PGWBI anxiety and total score improvements. This multi-disciplinary CR programme including diet therapy, exercise training and psychological counselling provides indication for short-term within-group effectiveness on functional exercise capacity, BMI and PGWBI in a sample of obese in-patients with CHD. However, controlled studies are needed to corroborate the results we found.

In-patient cardiac rehabilitation versus medical care - a prospective multicentre controlled 12 months follow-up in patients with coronary heart disease

BACKGROUND

The aim of this study was to evaluate a 3-week inpatient cardiac rehabilitation (Rehab) started early after the index event in patients with coronary heart disease and evidence-based secondary preventive medication.

METHOD

All patients had acute coronary angiography, 679 were discharged from hospital receiving usual care (Hosp), 795 completed a comprehensive Rehab. Follow-up was 12 months.

RESULTS

Rehab patients were older (64 vs. 62 years; p < 0.001), had more multivessel disease (51 vs. 37%; p < 0.001), heart failure (64 vs. 40%, p < 0.001), ST-segment elevation myocardial infarction (59 vs. 52%, p = 0.014), and renal insufficiency (10 vs. 7%, p = 0.036). Gender, peripheral artery disease, diabetes, hypertension, and socioeconomic status were similar in groups. Rehab patients had more beta-blockers (88 vs. 75%, p < 0.001) and angiotensin-converting enzyme inhibitors (81 vs. 70%, p < 0.001), a lower low-density lipoprotein cholesterol (102 vs. 122 mg/dl, p < 0.001), and a higher proportion of non-smokers (44 vs. 39%, p = 0.024). Primary combined endpoint of mortality, myocardial infarction (MI), revascularization, and hospitalization occurred in 32.6% of Rehab patients and in 38.7% of Hosp patients [p = 0.014; absolute risk reduction 0.0615, relative risk reduction 16%, number needed to treat (NNT) 17]. Myocardial infarction (MI) (1.8 vs. 3.8%, p = 0.015; NNT 49) and hospitalization (31.8 vs. 38.0%, p = 0.013; NNT 17) were reduced. In multivariate analysis, primary endpoint was reduced significantly (OR 0.729; 95% CI 0.585-0.909; p = 0.005) giving a relative risk reduction of 27% in favour of Rehab.

CONCLUSION

Although Rehab patients were sicker at entry, their outcome was substantially improved within 12 months. With very low NNT, Rehab is highly effective and should be advised to all suitable patients with coronary heart disease.

Depression and anxiety in chronic heart failure and chronic obstructive pulmonary disease: prevalence, relevance, clinical implications and management principles

OBJECTIVE

To review evidence regarding the prevalence, causation, clinical implications, aspects of healthcare utilisation and management of depression and anxiety in chronic heart failure and chronic obstructive pulmonary disease.

DESIGN

A critical review of the literature (1994-2009).

FINDINGS

The prevalence of depression and anxiety is high in both chronic obstructive pulmonary disease (8-80% depression; 6-74% anxiety) and chronic heart failure (10-60% depression; 11-45% anxiety). However, methodological weaknesses and the use of a wide range of diagnostic tools make it difficult to reach a consensus on rates of prevalence. Co-morbid depression and anxiety are associated with increased mortality and healthcare utilisation and impact upon functional disability and quality of life. Despite these negative consequences, the identification and management of co-morbid depression and anxiety in these two diseases is inadequate. There is some evidence for the positive role of pulmonary/cardiac rehabilitation and psychotherapy in the management of co-morbid depression and anxiety, however, this is insufficient to guide recommendations.

CONCLUSIONS

The high prevalence and associated increase in morbidity and mortality justifies future research regarding the management of anxiety and depression in both chronic heart failure and chronic obstructive pulmonary disease. Current evidence suggests that multi-faceted interventions such as pulmonary and cardiac rehabilitation may offer the best hope for improving outcomes for depression and anxiety.

Can a heart failure-specific cardiac rehabilitation program decrease hospitalizations and improve outcomes in high-risk patients?

BACKGROUND

Heart failure is a common and costly condition, particularly in the elderly. A range of models of interventions have shown the capacity to decrease hospitalizations and improve health-related outcomes. Potentially, cardiac rehabilitation models can also improve outcomes.

AIM

To assess the impact of a nurse-coordinated multidisciplinary, cardiac rehabilitation program to decrease hospitalizations, increase functional capacity, and meet the needs of patients with heart failure.

METHOD

In a randomized control trial, a total of 105 patients were recruited to the study. Patients in the intervention group received an individualized, multidisciplinary 12-week cardiac rehabilitation program, including an individualized exercise component tailored to functional ability and social circumstances. The control group received an information session provided by the cardiac rehabilitation coordinator and then follow-up care by either their cardiologist or general practitioner. This trial was stopped prematurely after the release of state-based guidelines and funding for heart failure programs.

RESULTS

During the study period, patients in the intervention group were less likely to have been admitted to hospital for any cause (44 vs. 69%, P = 0.01) or after a major acute coronary event (24 vs. 55%, P = 0.001). Participants in the intervention group were more likely to be alive at 12 months, (93 vs. 79%; P = 0.03) (odds ratio = 3.85; 95% confidence interval=1.03-14.42; P = 0.0042). Quality of life scores improved at 3 months compared with baseline (intervention t = o/-4.37, P<0.0001; control t = /-3.52, P<0.01). Improvement was also seen in 6-min walk times at 3 months compared with baseline in the intervention group (t = 3.40; P = 0.01).

CONCLUSION

This study shows that a multidisciplinary heart failure cardiac rehabilitation program, including an individualized exercise component, coordinated by a specialist heart failure nurse can substantially reduce both all-cause and cardiovascular readmission rates, improve functional status at 3 months and exercise tolerance.

Cardiac rehabilitation in Austria: long term health-related quality of life outcomes

BACKGROUND

The goal of cardiac rehabilitation programs is not only to prolong life but also to improve physical functioning, symptoms, well-being, and health-related quality of life (HRQL). The aim of this study was to document the long-term effect of a 1-month inpatient cardiac rehabilitation intervention on HRQL in Austria.

METHODS

Patients (N = 487, 64.7% male, age 60.9 +/- 12.5 SD years) after myocardial infarction, with or without percutaneous interventions, coronary artery bypass grafting or valve surgery underwent inpatient cardiac rehabilitation and were included in this long-term observational study (two years follow-up). HRQL was measured with both the MacNew Heart Disease Quality of Life Instrument [MacNew] and EuroQoL-5D [EQ-5D].

RESULTS

All MacNew scale scores improved significantly (p < 0.001) and exceeded the minimal important difference (0.5 MacNew points) by the end of rehabilitation. Although all MacNew scale scores deteriorated significantly over the two year follow-up period (p < .001), all MacNew scale scores still remained significantly higher than the pre-rehabilitation values. The mean improvement after two years in the MacNew social scale exceeded the minimal important difference while MacNew scale scores greater than the minimal important difference were reported by 40-49% of the patients.Two years after rehabilitation the mean improvement in the EQ-5D Visual Analogue Scale score was not significant with no significant change in the proportion of patients reporting problems at this time.

CONCLUSION

These findings provide a first indication that two years following inpatient cardiac rehabilitation in Austria, the long-term improvements in HRQL are statistically significant and clinically relevant for almost 50% of the patients. Future controlled randomized trials comparing different cardiac rehabilitation programs are needed.

Review of nursing care for patients undergoing percutaneous coronary intervention: a patient journey approach

AIM

To evaluate the existing literature to inform nursing management of people undergoing percutaneous coronary intervention. BACKGROUND. Percutaneous coronary intervention is an increasingly important revascularisation strategy in coronary heart disease management and can be an emergent, planned or rescue procedure. Nurses play a critical role in delivering care in both the independent and collaborative contexts of percutaneous coronary intervention management.

DESIGN

Systematic review.

METHOD

The method of an integrative literature review, using the conceptual framework of the patient journey, was used to describe existing evidence and to determine important areas for future research. The electronic data bases CINAHL, Medline, Cochrane and the Joanna Briggs data bases were searched using terms including: (angioplasty, transulminal, percutaneous coronary), nursing care, postprocedure complications (haemorrhage, ecchymosis, haematoma), rehabilitation, emergency medical services (transportation of patients, triage).

RESULTS

Despite the frequency of the procedure, there are limited data to inform nursing care for people undergoing percutaneous coronary intervention. Currently, there are no widely accessible nursing practice guidelines focusing on the nursing management in percutaneous coronary intervention. Findings of the review were summarised under the headings: Symptom recognition; Treatment decision; Peri-percutaneous coronary intervention care, describing the acute management and Postpercutaneous coronary intervention management identifying the discharge planning and secondary prevention phase.

CONCLUSIONS

Cardiovascular nurses need to engage in developing evidence to support guideline development. Developing consensus on nurse sensitive patient outcome indicators may enable benchmarking strategies and inform clinical trial design.

RELEVANCE TO CLINICAL PRACTICE

To improve the care given to individuals undergoing percutaneous coronary intervention, it is important to base practice on high-level evidence. Where this is lacking, clinicians need to arrive at a consensus as to appropriate standards of practice while also engaging in developing evidence. This must be considered, however, from the central perspective of the patient and their family.

Reframing the dilemma of poor attendance at cardiac rehabilitation: an exploration of ambivalence and the decisional balance

AIM

To discuss the problem of poor attendance at cardiac rehabilitation from the alternative perspective of patient ambivalence.

BACKGROUND

Evidence supports the benefits of cardiac rehabilitation as a means for secondary prevention of coronary heart disease, yet current literature continues to document poor attendance at these programmes. Whilst extrinsic factors, such as transportation and lack of physician support have been identified as barriers, patients who choose not to attend these programmes are often described as lacking motivation or being non-compliant. However, it is possible that non-attendance is the result of ambivalence - the experience of simultaneously wanting to and yet not wanting to, or the 'I want to, but I don't want to' dilemma.

DESIGN

Discussion paper.

METHOD

This discussion paper draws on the literature of ambivalence and decision-making theory to reframe the issue of poor attendance at cardiac rehabilitation.

CONCLUSIONS

This paper has demonstrated that the problem of poor attendance may be explained from the perspective of patient ambivalence and that using strategies such as the decisional balance may assist these individuals in exploring their ambivalence to engage in secondary prevention programmes.

RELEVANCE TO CLINICAL PRACTICE

Understanding the dynamics of ambivalence provides an alternative to thinking of patients as lacking motivation, being non-compliant, or even resistant. Helping patients to explore and resolve their ambivalence may be all that is needed to help them make a decision and move forward.

Health-related quality of life in patients with coronary heart disease after residential vs ambulatory cardiac rehabilitation

BACKGROUND

The aim of this study was to evaluate the influence of residential (RCR) vs ambulatory (ACR) cardiac rehabilitation (CR) on health-related quality of life (QOL) connected with changes in exercise capacity of patients with coronary heart disease (CHD).

METHODS AND RESULTS

The 562 patients with CHD were studied: 313 participants in RCR and 249 participants in ACR. The examination was performed at the beginning of CR and after 8 weeks. QOL was assessed using the EuroQuol 5D (EQ-5D) and SF36 questionnaires. Exercise testing was performed with evaluation of workload during the last stage of the test and rate of perceived exertion intensity. In the first examination, patients from both groups did not differ significantly. After 8 weeks, a similar improvement in QOL was observed in both settings of CR according to EQ-5D and SF36 results. Health status was improved by 11.1% in the RCR group and by 10.4% in the ACR group. Last workload's intensity increased significantly by 32.1% in the RCR group and by 38.1% in the ACR group. The rate of perceived exertion intensity did not change despite the bigger workloads during the exercise test.

CONCLUSIONS

Comprehensive CR improves health-related QOL and exercise capacity without differences between residential and ambulatory models.

Marital status and cardiac rehabilitation attendance: a meta-analysis

BACKGROUND

Marital status has been clearly linked to subsequent health outcomes in those with established coronary heart disease (CHD). This robust association may be because of both pathophysiological and behavioural mechanisms.

DESIGN

We employed meta-regression to examine the association between marital status and attendance at outpatient cardiac rehabilitation (CR) in published studies.

METHODS

We searched electronic databases, for example, Medline and Science Citation Index, for published studies that reported an association between a measure of marital or partnered status and CR attendance in patients with diagnosed CHD.

RESULTS

Eleven studies were identified which incorporated 6,984 CHD patients. Being married/partnered was associated with significantly higher odds of attending CR. Using a fixed effects model, the pooled odds ratio of CR attendance was 1.72 [95% confidence interval (CI) 1.50-1.97] for those who were married/partnered. There was no evidence of heterogeneity of effects (P=0.42) or publication bias (P=0.12).

CONCLUSION

CHD patients who are married or have a partner are between 1.5-2 times more likely to attend CR. Associations between marital status and CR attendance may partly explain CHD outcomes.

The validity and reliability of the Turkish version of the MacNew Heart Disease Questionnaire in patients with angina

AIMS AND OBJECTIVES

Health-related quality of life (HRQL) is an important patient-reported outcome when identifying the effects of the angina and evaluating the efficacy of treatment. The aim of this study was to determine the reliability and validity of the Turkish version of the MacNew Heart Disease HRQL Questionnaire (MacNew) in patients with angina.

METHOD

The Short Form SF-36, the MacNew, and the Hospital Anxiety and Depression Scale were completed by the 125 patients in first 2-3 days after admission to the coronary care unit. Internal consistency reliability (Cronbach's alpha) and reproducibility (intraclass correlation coefficients, ICC) of the MacNew were assessed, and test-retest reproducibility was evaluated over a 2-month period in 25 clinically stable patients.

RESULTS

The original three-factor structure for the Turkish MacNew was confirmed, with construct validity only partially confirmed; reliability statistics show that Cronbach's alpha exceeded 0.80 and the ICC exceeded 0.60 for all MacNew scales. Discriminative validity of the MacNew was confirmed.

CONCLUSION

The MacNew appears to be reliable and valid in Turkish patients with angina.
