A Novel Home-based Physical Activity Intervention for Stable Chronic Heart Failure Patients (PAHF)
Personalised Home-based Physical Activity Intervention in Older Adults With Heart Failure: Advancing Towards an Effective Clinical Therapy
The project focuses on heart failure (HF), a complex clinical syndrome of symptoms and signs that suggest the efficiency of the heart as a pump is impaired. Around 950,000 people in the UK have HF. Both the incidence and prevalence of heart failure increase steeply as a result of an ageing population, improved survival of people with ischaemic heart disease and more effective treatments for heart failure. Aside from the obvious individual burden HF also accounts for 1 million inpatient bed days - 2% of all NHS inpatient bed days and 5% of all emergency medical admissions to hospital which are projected to rise by 50% over the next 25 years. There is a pressing need to explore effective ways to manage the individual and societal burden of HF.
Despite exercise being an effective, safe, and a recommended (class I) therapy for people with heart failure according to clinical guidelines from the UK, EU, and USA, it is currently out of reach for majority people with HF. This project addresses this directly by designing and evaluating an exercise therapy that will be available to those living with HF with potential to improve their symptoms, function and quality of life

Description détaillée
The present project aligns with Ageing Body Theme of the Newcastle NIHR Biomedical Research Centre. In particular the Chronic Cardiac Disease theme because it focuses on Heart Failure and how to improve clinical care and outcomes, physical function and quality of life of those living with heart failure. The project will develop and evaluate a novel non-pharmacological therapeutic approach (home-based exercise programme with behavioural support) which recognises the complexity of heart failure and the need to treat each individual patient in an optimal way. Such therapy will be tailored for people with heart failure who are, under current clinical care, lacking the well-recognised benefits associated with exercise therapy. After initial evaluation, it is expected that this project will inform development of a large definitive trial (subject to separate funding application) which findings will be translated into clinical care to improve outcomes in people with heart failure. Results of such a trial are expected to have a significant impact on current clinical practice and the development of new cardiac rehabilitation guidelines for heart failure.
It is important to indicate that home-based exercise cardiac rehabilitation programmes have been introduced in an attempt to widen access and participation as an alternative to supervised centre-based rehabilitation in conditions other than heart failure. Home-based exercise programmes are reported to be equally effective as centre based programmes in people with coronary artery disease i.e. following myocardial infarction and/or revascularisation, but remain to be designed and evaluated in those living with heart failure and this is subject to the present investigation

Quality of Life Score using Minnesota living with heart failure questionnaire
Délai: 2 years

This is a qualitative marker which will be assessed using the Minnesota Living with Heart Failure Questionnaire.
Pre and post intervention scores will be analysed to assess differences in this outcome.

Maximum Oxygen Consumption (ml/Kg/min) Post intervention
Délai: 2 years

This is a marker of overall fitness levels and the investigators shall sample data pre and post intervention to assess changes in fitness during the intervention

Haemodynamic markers (cardiac output, stroke Volume)
Délai: 2 years
|
Cardiac output (L/min) is the amount of blood pumped out of the ventricles per minute while stroke volume (ml/beat) is the amount of blood pumped out of the heart per beat.
Both markers gives an indication of cardiac function and higher values during exercise indicates better functioning of the heart.
The investigators shall evaluate these markers pre and post intervention
