Background and study aims
Patients with chronic heart failure (CHF) experience exacerbations (flare-ups) or worsening of their symptoms which sometimes require a hospital admission. Evidence strongly suggests that exacerbations cause levels of strength and physical activity to decline and also increase the chance of readmission to hospital. Rehabilitation (exercise and education) has been proven to be beneficial for patients with stable CHF in terms of improving muscle strength, exercise tolerance and quality of life. However, we currently do not know the effects of starting a rehabilitation programme immediately after hospitalisation for an acute exacerbation of CHF on physical functioning, psychological state and healthcare usage. This study is needed in order to tell us whether or not a programme of rehabilitation immediately after an exacerbation might be effective in improving patient care.
Who can participate?
Patients aged 40 - 90 admitted to the acute medical units of the trial hospital with an acute exacerbation of CHF.
What does the study involve?
Patients will be randomly allocated to one of two groups. One group receives standard best usual care and the other group receives usual care plus early rehabilitation (intervention group). We will take basic details (age, gender, current medication, height and weight etc.) and discuss previous medical history. Subjects will be asked to walk between two points at a set pace until they need to stop. Subjects will complete some questionnaires about health status. This will give us a guide to how their condition affects their daily life. The strength of the thigh muscle will be measured using a strain gauge. This involves sitting on a chair and extending the leg which is attached to a strap. Physical activity will be recorded for 24 hours whilst patients are in hospital (day 2 or 3 of admission) using a portable, lightweight activity monitor worn on the upper arm. After this, we will measure physical activity for two consecutive weekdays after their hospital discharge and 3-month assessment visits. We will record any GP visits, A&E visits or hospital admissions for the duration of the study. If patients are assigned to the standard care group they will receive best usual care from the medical and multidisciplinary teams managing them. This will involve follow-up at home from the Heart Failure Community Nursing Teams and an outpatient appointment with a consultant. These patients will be offered the chance to attend rehabilitation after their 3-month assessment visit. If patients are assigned to the rehabilitation (intervention) group they will attend outpatient classes twice a week for 8 weeks within 4 weeks of leaving hospital. The exercise part of the class lasts for one hour and involves a circuit of exercises (walking, bike, hand weights etc.). Exercise will be individualised, that is, adapted and progressed depending on the subjects fitness level. The second hour of each class involves self-management education delivered by a multi-disciplinary team and checking of home exercise diaries.
What are the possible benefits and risks of participating?
There may not be any direct benefit to participants who decide to take part. However, it is hoped that we may find that the rehabilitation intervention will benefit patients in terms of improved muscle strength, improved physical activity levels and fewer readmissions to hospital. We would also hope that taking part in the research may help our understanding of the recovery process following an exacerbation. The study will inform both present and future rehabilitation services, therefore benefiting all CHF patients. There are minimal identified risks to taking part in this research. Patients may experience some muscle aching and general tiredness from starting the exercise programme and performing the walking tests. This is usually mild and wears off after a couple of days. The staff supervising the classes are highly experienced and will monitor patients closely. We appreciate that the wearing of an activity monitor might be a slight inconvenience for some patients. However, they are very light and we have used these monitors in recent research studies and they have been very well tolerated by patients. Patients will be asked to make additional visits to hospital over the 3-month study period. This is a potential inconvenience but in our experience, most patients are happy to attend. Travel expenses will be reimbursed or a taxi provided for these assessment visits.

| Scientific title | Early REhabilitation after hospitalisation for an Acute exaCerbaTion of Chronic Heart Failure: a randomised controlled trial. |
| Study acronym | REACT-CHF |
| Study objectives | An effective rehabilitation strategy delivered early after hospitalisation for an acute exacerbation (AE) of heart failure will lead to improvements in exercise capacity and health status, as it does in patients with stable disease. |
| Ethics approval(s) | Leicestershire, Northamptonshire and Rutland Research Ethics Committee 2, 02/08/2010, ref: 10/H0402/48 |
| Health condition(s) or problem(s) studied | Chronic heart failure (CHF) |
| Intervention | Patients admitted to the acute medical units of the trial hospital with an acute exacerbation of CHF and are able to give informed consent will be invited to participate in the study, on day 2 or 3 of their inpatient stay. Patients will be randomised to receive either: 1. Standard 'best usual' care: Patients in the control group can expect to be discharged with 'best usual' care. This will involve follow-up in Primary Care by the Heart Failure Community Nursing Teams and an outpatient appointment with a cardiology consultant, as per usual. They will also be required to attend the assessment visits (at baseline, at discharge from hospital and at 3 months; see section on outcomes). Those assigned to the control group will be offered rehabilitation after their 3-month assessment if desired. 2. Rehabilitation: Those assigned to the intervention group can expect to receive standard 'best usual' care in addition to an early rehabilitation programme. The rehabilitation intervention is designed to be a comprehensive package of care consisting of exercise training and self-management education, delivered by a multidisciplinary team. Prior to discharge from hospital, outcome measures will be taken and randomisation made. Patients will then attend the rehabilitation classes at the next available opportunity (within 10 days of hospital discharge). Rehabilitation will consist of supervised classes (1/2 per week) for 6 - 8 weeks. The exercise component of the class lasts for 1 hour (warm-up, aerobic and resistance exercises and cool-down). Patients are closely monitored throughout the classes for symptoms [Borg breathlessness and perceived exertion scores, heart rate (HR), blood pressure (BP)]. The classes are supervised by specialist Cardiac Rehabilitation Nurses and Physiotherapists. Patients will also be expected to complete a Home Exercise Programme (HExP) most days of the week. This programme will mirror exercise prescription from the supervised classes. There will be various education sessions delivered by a multidisciplinary team lasting for 1 hour: diet, exercise, disease education, self-management, medications, and living with a long-term condition and checking HExP diaries/setting new training targets. 3 month follow-up assessment to re-assess exercise tolerance and quality of life. |

Eligibility
| Participant type(s) | Patient |
|---|---|
| Age group | Adult |
| Sex | Both |
| Target number of participants | 56 |
| Key inclusion criteria | 1. Patients admitted to the acute medical units of the trial hospital with an acute exacerbation of chronic heart failure (CHF) 2. Able to give informed consent 3. Aged 40 - 90 years 4. Patients admitted with an established diagnosis of CHF (documented left ventricular systolic dysfunction [LVSD]) will be independently assessed for suitability 5. Patients will have received optimal medical management 6. Impaired exercise tolerance (New York Heart Association [NYHA] classifications II - IV) |
| Key exclusion criteria | 1. Patients admitted for planned surgery 2. Patients with musculoskeletal or neuromuscular condition that significantly contributes to exercise limitation 3. Psychiatric or neurological conditions that would render the patient unable to comply with the training either in hospital or at home 4. Patients who have a new diagnosis of heart failure on admission will be excluded as they are likely to need ongoing medical management (i.e. establishing the correct drug regimen) and probably wont display the same declines in physical activity as those with established chronic heart failure. 5. Usual exclusion criteria to our current out-patient exercise programme will apply: 5.1. Unstable ischaemic heart disease 5.2. Myocardial infarction (MI) within the previous 3 weeks 5.3. Planned coronary revascularization/pacemaker implantation in the next 6 months 5.4. New onset of atrial fibrillation (AF) 5.5. Complex ventricular arrhythmia 5.6. Significant regurgitant valvular disease requiring surgery 5.7. Moderate/severe aortic stenosis 5.8. Hypertrophic obstructive cardiomyopathy 5.9. Acute pericarditis or myocarditis 5.10. Recent embolism or thromboembolism 6. Terminal disease with an estimated survival time of less than 3 months to live. Medical advice may need to be sought in these cases. 7. Those with previous attendance at rehabilitation within the preceding 12 months. This includes CHF rehabilitation and rehabilitation for post-MI/angina/re-vascularisation. 8. We know in chronic obstructive pulmonary disease (COPD) that the benefits of rehabilitation have been shown to persist for 12 months. Due to the probability of multiple factors being present (such as inability to cope at home), patients will be excluded if they have had four or more hospitalisations for an acute exacerbation of their disease in the preceding 12-month period (currently only 1.1% of patients in UHL are readmitted more than four times within 12 months). In our experience these patients frequently have significant social and psychological problems triggering hospitalisation that would not be modifiable with the proposed intervention. |
