Feasibiliy, safety and patient perceptions of an exercise-based cardiac telerehabilitation programme

Abstract Background Despite proven benefits of exercise-based cardiac rehabilitation (EBCR), few patients with myocardial infarction (MI) complete these programs and there is a need to develop more flexible and evidence-based options. Purpose The aim of this study was to evaluate feasibility, safety, and patient perceptions of remotely delivered EBCR. Methods This study was conducted at 23 cardiac rehabilitation centres during the Covid-19 pandemic (March 2020-September 2022), when access to centre-based EBCR was restricted. A total of 231 patients with MI <80 years were included 2-4 weeks after discharge to participate in a remote EBCR programme 2 times/week for 3-4 months. Exercise was delivered through a real-time group-based video meeting, connecting the physiotherapist to patients exercising at home. Safety monitoring in terms of adverse events (AE) and serious adverse events (SAE) were recorded. Outcomes were assessed before and after remote EBCR completion and comprised tests of physical fitness and questionnaires: self-reported physical activity and exercise (Haskell questionnaire), physical capacity (VAS), kinesiophobia (TSK-Heart), health-related quality of life (EQ5D-VAS), self-efficacy for exercise, and patient acceptance of the program. Results Patients performed in median 19 (Q1 9 - Q3 23) remote EBCR sessions. A total of 16 AEs were registered during exercise (e.g chest pain, syncope, dizziness, musculoskeletal symptoms) which were all resolved. Two SAEs that required hospitalization were reported (chest pain, in-stent restenosis), both unrelated to exercise. At end of remote EBCR, significant improvements in physical fitness, self-reported exercise and physical capacity, kinesiophobia, and health-related quality of life were observed (Table 1). Delta values were similar to previous centre-based EBCR studies. Patients agreed that remote EBCR improved health care access (83%), was easy to use (94%), and 95% found exercise performance and interaction acceptable. Conclusions This study supports that remote EBCR is feasible and safe with a high patient acceptance post-MI. The clinical effectiveness needs to be confirmed in a randomized controlled design.
