A remotely delivered home-based physical activity intervention for pulmonary hypertension patients

McCormack, Ciara orcid logoORCID: 0000-0003-4508-5522 (2022) A remotely delivered home-based physical activity intervention for pulmonary hypertension patients. PhD thesis, Dublin City University.

Pulmonary hypertension (PH) is a heterogeneous condition, associated with a high symptom burden and a substantial loss of exercise capacity. Despite prior safety concerns regarding physical exertion, exercise training as a supportive therapy is now, recommended for PH patients. Exercise training improves both functional capacity and quality of life (QoL) among PH patients. However, physical activity (PA) levels remain low and opportunities to engage in exercise training in this patient cohort remains limited. Currently most programs are hospital-based which limits accessibility. There is a need to provide alternative approaches for PA engagement for PH patients. The aim of this PhD research was to develop, implement and evaluate the safety, feasibility, and efficacy of home-based PA intervention for adults with PH. Formative research, that consisted of 1:1 semi-structured interviews was conducted to assist with the design of the intervention along with input from PH clinician’s. PH patients identified fear as a major barrier to exercise. They also desired clinician supports for exercise engagement and a preference for home-based delivery. A home-based exercise intervention underpinned by theory and informed by end-users, was assessed using a single-arm feasibility study design. Participants (n=19; 80% female) with a mean (±SD) age of 49.9±15.9 yr) with a diagnosis of PH undertook a 10-week, home-based exercise intervention with induction training, support materials, telecommunication support, health coaching, exercise training and fitness assessments all remotely delivered. Training involved respiratory training along with a combination of aerobic and resistance exercises. No adverse events were reported and, the intervention was well received by the participants. There was a significant improvement in PA levels, functional capacity, QOL, exercise self-efficacy and 6-min walk distance between baseline and post-training. The present study demonstrates that a 100% remotely delivered HBEP is safe, feasible and effective in improving, QoL, functional capacity and PA levels in PH patients.
