Pilot Testing of an Online Rehabilitation Intervention for People With Heart Failure (PORIAS-HF).

Group A participants will be invited to attend up to 24 exercise sessions (2 sessions per week and a 3rd optional) and 2 virtual (online; a 3rd will be optional) HF workshops over 8 weeks. All sessions will be delivered via online platforms, with 1 facilitator supporting up to 8 participants simultaneously in each session.

Group B participants will be provided with a self-care exercise programme. The exercise programme will be home-based with a mixture of online video calls and telephone support contacts, alternating once every other week. The video or telephone contacts will be mutually agreed by the patient and the facilitator at a mutually convenient time and will aim to support Group B participants, by offering advice and tracking progress. Patients will be provided with two exercise programmes: I) a chair-based exercise programme (DVD will be provided), and ii) a progressive walking training programme (a manual will be provided). Patients will be advised to exercise ≥3 times per week, starting from their own personal level and gradually building up over 8 weeks in session's duration, frequency of sessions per week, and walking pace.
