Cardiac Rehabilitation: Are People With Stroke or Transient Ischaemic Attack Being Included? A Cross-Sectional Survey

Mechanisms and benefits of cardiac rehabilitation in individuals with stroke: emerging role of its impact on improving cardiovascular and neurovascular health

Human and animal studies have demonstrated the mechanisms and benefits of aerobic exercise for both cardiovascular and neurovascular health. Aerobic exercise induces neuroplasticity and neurophysiologic reorganization of brain networks, improves cerebral blood flow, and increases whole-body VO2peak (peak oxygen consumption). The effectiveness of a structured cardiac rehabilitation (CR) program is well established and a vital part of the continuum of care for people with cardiovascular disease. Individuals post stroke exhibit decreased cardiovascular capacity which impacts their neurologic recovery and extends disability. Stroke survivors share the same risk factors as patients with cardiac disease and can therefore benefit significantly from a comprehensive CR program in addition to neurorehabilitation to address their cardiovascular health. The inclusion of individuals with stroke into a CR program, with appropriate adaptations, can significantly improve their cardiovascular health, promote functional recovery, and reduce future cardiovascular and cerebrovascular events thereby reducing the economic burden of stroke.

Integrating Cardiac Rehabilitation in Stroke Recovery

Stroke remains a top contributor to long-term disability in the United States and substantially limits a person's physical activity. Decreased cardiovascular capacity is a major contributing factor to activity limitations and is a significant health concern. Addressing the cardiovascular capacity of stroke survivors as part of poststroke management results in significant improvements in their endurance, functional recovery, and medical outcomes such as all-cause rehospitalization and mortality. Incorporation of a structured approach similar to the cardiac rehabilitation program, including aerobic exercise and risk factor education, can lead to improved cardiovascular function, health benefits, and quality of life in stroke survivors.

Sex Differences in Depressive Symptoms in 1308 Patients Post-Stroke at Entry to Cardiac Rehabilitation

PURPOSE

The objective of this study was to determine whether a sex difference exists in the prevalence of post-stroke depressive symptoms (PSDS) at entry to cardiac rehabilitation (CR) and to determine the correlates of PSDS in all patients, and in women and men separately.

METHODS

People post-stroke at entry to CR from database records (2006-2017) were included. Bivariate analyses identified PSDS correlates (≥16 on the Center for Epidemiologic Studies Depression Scale) in all patients and women and men separately.

RESULTS

Patients (n = 1308, 28.9% women), mean age of 63.9 ± 12.9 yr, were 24.2 ± 9.9 mo post-stroke at CR entry. Among all patients, 30.0% had PSDS. A greater proportion of women than men had PSDS (38.6 vs 26.6%; P < .001). Correlates of PSDS in all patients were sex (women) (OR = 1.6: 95% CI, 1.14-2.12), being unemployed, ≤60 yr old, prescribed antidepressant medication, having lower cardiorespiratory fitness (peak oxygen uptake [V̇ o2peak ]), chronic obstructive pulmonary disease (COPD), higher body mass index (BMI), no transient ischemic attack, and longer time from stroke to CR entry (>12 mo). Correlates in women were being obese (BMI ≥ 30), 51-70 yr old, prescribed antidepressant medication, and not married. Correlates in men were being ≤60 yr old, unemployed, prescribed antidepressant medication, having lower V̇ o2peak , sleep apnea, COPD, and no hypertension.

CONCLUSION

Women were disproportionately affected by PSDS at entry to CR in bivariate and multivariable analyses. Women and men had mostly unique correlates of PSDS, indicating tailored strategies to address PSDS are required. PSDS disproportionately affected patients with longer delay to CR entry, suggesting efforts should target timely referral to facilitate earlier and repeated assessments and management.

Co-Designed Cardiac Rehabilitation for the Secondary Prevention of Stroke (CARESS): A Pilot Program Evaluation

Structured health system-based programs, such as cardiac rehabilitation, may reduce the risk of recurrent stroke. This study aimed to co-design and evaluate a structured program of rehabilitation, developed based on insights from focus groups involving stroke survivors and health professionals. Conducted in Tasmania, Australia in 2019, the 7-week program comprised one hour of group exercise and one hour of education each week. Functional capacity (6 min walk test), fatigue, symptoms of depression (Patient Health Questionnaire), and lifestyle were assessed pre- and post-program, with a historical control group for comparison. Propensity score matching determined the average treatment effect (ATE) of the program. Key themes from the co-design focus groups included the need for coordinated care, improved psychosocial management, and including carers and peers in programs. Of the 23 people approached, 10 participants (70% men, mean age 67.4 ± 8.6 years) completed the program without adverse events. ATE analysis revealed improvements in functional capacity (139 m, 95% CI 44, 234) and fatigue (-5 units, 95% CI -9, -1), with a small improvement in symptoms of depression (-0.8 units, 95% CI -1.8, 0.2) compared to controls. The co-designed program demonstrated feasibility, acceptability, and positive outcomes, suggesting its potential to support stroke survivors.

Is early initiated cardiorespiratory fitness training within a model of stroke-integrated cardiac rehabilitation safe and feasible?

OBJECTIVE

To investigate the safety and feasibility of an early initiated stroke-integrated Cardiac Rehabilitation program.

METHODS

People with acute first or recurrent ischaemic stroke, admitted to Epworth HealthCare were screened for eligibility and invited to participate. In addition to usual care neurorehabilitation, participants performed 1) cardiorespiratory fitness training 3-days/week during inpatient rehabilitation (Phase 1), and/or 2) 2-days/week centre-based cardiorespiratory fitness training plus education and 1-day/week home-based cardiorespiratory fitness training for 6-weeks during outpatient rehabilitation (Phase 2). Safety was determined by the number of adverse and serious adverse events. Feasibility was determined by participant recruitment, retention, and attendance rates, adherence to exercise recommendations, and participant satisfaction.

RESULTS

There were no study-related adverse or serious adverse events. Of 117 eligible stroke admissions, 62 (53%) were recruited, while 10 (16.1%) participants withdrew. Participants attended 189 of 201 (94%) scheduled cardiorespiratory fitness training sessions in Phase 1 and 341/381 (89.5%) scheduled sessions in Phase 2. Only 220/381 (58%) scheduled education sessions were attended. The minimum recommended cardiorespiratory fitness training intensity (40% heart rate reserve) and duration (20 minutes) was achieved by 57% and 55% of participants respectively during Phase 1, and 60% and 92% respectively during Phase 2. All respondents strongly agreed (69%) or agreed (31%) they would recommend the stroke-integrated Cardiac Rehabilitation program to other people with stroke.

CONCLUSION

Cardiorespiratory fitness training in line with multiple clinical practice guidelines included within a model of stroke-integrated Cardiac Rehabilitation appears to be safe and feasible in the early subacute phase post-stroke.

Perspectives of cardiac rehabilitation in patients who had a stroke: a protocol for a qualitative study review

INTRODUCTION

Stroke has a high incidence and disability rate, and its recurrence and readmission rates are rising, making it the second-leading cause of mortality in the globe. Cardiac rehabilitation is a well-known, evidence-based strategy that might serve as an additional preventative programme. Prior quantitative research has proven the positive results and high practicability of cardiac rehabilitation for patients who had a stroke, however, cardiac rehabilitation is not yet a routine component of stroke rehabilitation worldwide. It might be useful to conduct meta-integration of previous qualitative studies to understand if existing cardiac rehabilitation programme meets the needs of patients who had a stroke. Therefore, the purpose of this study is to combine systematically the perspectives on benefits, barriers and facilitating factors of cardiac rehabilitation in patients who had a stroke.

METHODS AND ANALYSIS

There will be a search of PubMed, Web of Science, Embase, Scopus, CINAHL and PsycINFO databases. In addition, grey literature from Google Scholar, OpenGrey, PyARXiv, bioRxiv and medRxiv will also be searched. Included studies will be qualitative studies or findings from mixed-method research involving patients who engage in CR after a stroke. Regardless of the publishing date and context, English-language articles will be reviewed. Two impartial reviewers will screen studies and extract data from the included studies. According to the Joanna Briggs Institute Centre for Evidence-Based Health Care Quality Evaluation Criteria for qualitative research, the methodology of the included literature will be examined. For data synthesis, the pooling meta-integration approach and Noblit and Hare's seven steps of meta-ethnography will be used.

ETHICS AND DISSEMINATION

Because there will be no collection of primary data, this systematic review is exempt from the need that gets ethical approval. The findings of the review will be made public by publishing them in scholarly journals and presenting them at scientific conferences.

Cardiovascular Rehabilitation for transient ischaemic Attack and Mild Stroke: the CRAMS effectiveness-implementation hybrid study protocol

BACKGROUND

Internationally, stroke and cardiac rehabilitation clinicians agree that current cardiac rehabilitation models are a suitable secondary prevention program for people following a transient ischaemic attack (TIA) or mild stroke. There is strong evidence for exercise-based cardiac rehabilitation in people with heart disease, however, the evidence for cardiac rehabilitation post-TIA or stroke is limited. Here we will explore the effectiveness and implementation of an integrated (TIA, mild stroke, heart disease) traditional exercise-based cardiovascular rehabilitation (CVR) program for people with TIA or mild stroke over 6-months.

METHODS

This type 1 effectiveness-implementation hybrid study will use a 2-arm single-centre assessor-blind randomised controlled trial design, recruiting 140 participants. Adults who have had a TIA or mild stroke in the last 12-months will be recruited by health professionals from hospital and primary healthcare services. Participants will be assessed and randomly allocated (1:1) to the 6-week CVR program or the usual care 6-month wait-list control group. Distance completed in the 6-min walk test will be the primary effectiveness outcome, with outcomes collected at baseline, 6-weeks (complete CVR) and 6-months in both groups. Other effectiveness outcome measures include unplanned cardiovascular disease-related emergency department and hospital admissions, daily minutes of accelerometer moderate-to-vigorous physical activity, body mass index, waist circumference, blood pressure, quality of life, anxiety and depression. Implementation outcomes will be assessed using the Reach, Effectiveness, Adoption, Implementation, Maintenance (RE-AIM) framework, including a cost-effectiveness analysis. Semi-structured interviews will be conducted with participants and CVR program health professionals, investigating the acceptability, value, and impact of the CVR program. Qualitative analyses will be guided by the Consolidated Framework for Implementation Research.

DISCUSSION

Few studies have assessed the effectiveness of cardiac rehabilitation for people with TIA and mild stroke, and no studies appear to have investigated the cost-effectiveness or implementation determinants of such programs. If successful, the CVR program will improve health outcomes and quality of life of people who have had a TIA or mild stroke, guiding future research, policy, and clinical practice, reducing the risk of repeat heart attacks and strokes for this population.

Post pandemic research priorities: A consensus statement from the HL-PIVOT

We have been amid unhealthy living and related chronic disease pandemics for several decades. These longstanding crises have troublingly synergized with the coronavirus disease 2019 (COVID-19) pandemic. The need to establish research priorities in response to COVID-19 can be used to address broad health and wellbeing, social and economic impacts for the future is emerging. Accordingly, this paper sets out a series of research priorities that could inform interdisciplinary collaboration between clinical sciences, public health, business, technology, economics, healthcare providers, and the exercise science/sports medicine communities, among others. A five-step methodology was used to generate and evaluate the research priorities with a focus on broad health and well-being impacts. The methodology was deployed by an international and interdisciplinary team from the Healthy Living for Pandemic Event Protection (HL- PIVOT) network. This team were all engaged in responding to the Pandemic either on the 'front-line' and/or in leadership positions ensuring the currency and authenticity of the process. Eight research priorities were identified clustered into two groups: i) Societal & Environmental, and ii) Clinical. Our eight research priorities are presented with insight from previously published research priorities from other groups.

Including Patients With Stroke in Cardiac Rehabilitation: BARRIERS AND FACILITATORS

More than 13 million cases of stroke are occurring annually worldwide. Approximately a quarter of these strokes are recurrent strokes, and there is compelling evidence of the benefit of supervised exercise and risk factor modification programming in the secondary prevention of these strokes. However, there is insufficient time in inpatient and outpatient stroke rehabilitation for focused exercise interventions. General lifestyle interventions on their own, without guidance and supervision, are insufficient for improving physical activity levels. Cardiac rehabilitation (CR) is a setting where cardiac patients, and increasingly stroke patients, receive comprehensive secondary prevention programming, including structured exercise. Unfortunately, not all CR programs accept referrals for people following a stroke and for those that do, only a few patients participate. Therefore, the purpose of this review is to report the barriers and facilitators to improving linkage between health services, with a focus on increasing access to CR. In the next two decades, it is projected that there will be a marked increase in stroke prevalence globally. Therefore, there is an urgent need to create cross-program collaborations between hospitals, outpatient stroke rehabilitation, CR, and community programs. Improving access and removing disparities in access to evidence-based exercise treatments would positively affect the lives of millions of people recovering from stroke.

Inclusion of People Poststroke in Cardiac Rehabilitation Programs in Canada: A Missed Opportunity for Referral

BACKGROUND

Evidence supports establishing a continuum of care from stroke rehabilitation (SR) to cardiac rehabilitation programs (CRPs). It is not known to what extent people poststroke are being integrated. This study aimed to determine the proportion of CRPs that accept referrals poststroke, barriers/facilitators, and eligibility criteria.

METHODS

A web-based questionnaire was sent to CRPs across Canada.

RESULTS

Of 160 questionnaires sent, 114 representatives (71%) of 130 CRPs responded. Of respondents, 65% (n = 74) reported accepting people with a diagnosis of stroke and doing so for a median of 11 years, 11 offering stroke-specific classes and an additional 6 planning inclusion. However, 62.5% of CRPs reported that < 11 patients participated in the last calendar year despite 88.5% reporting no limit to the number they could enroll. Among CRPs, 25% accepted only patients with concurrent cardiac diagnoses, living in the community (47.8%), and without severe mobility (70.1%), communication (80.6%), or cognitive (85.1%) deficits. The 2 most influential barriers and facilitators among all CRPs were funding and staffing. The fourth greatest barrier was lack of poststroke referrals, and third to sixth facilitators were SR/CRP collaboration to ensure appropriate referrals (third) and to increase referrals (sixth), toolkits for prescribing resistance (fourth), and aerobic training (fifth). CRP characteristics associated with accepting stroke were a hybrid program model, a medium program size, and having a falls prevention component.

CONCLUSIONS

Most CRPs accept patients poststroke, but few participate. Therefore, establishing SR/CRP partnerships to increase appropriate referrals, using a toolkit to help operationalize exercise components, and allocating funding/resources to CRPs may significantly increase access to secondary prevention strategies.
