Cardiac rehabilitation has traditionally been administered through face-to-face consultations with a specialised team of nurses, medical doctors and physiotherapists. However, the healthcare system is undergoing a significant digital transformation, which may lead to telemedicine (TM) becoming a cornerstone of healthcare. However, successful TM requires digital competencies among both patients and health professionals. This trial will examine the best methods of onboarding patients to TM by way of a co-designed cardiac telerehabilitation model with a family-focused approach.

The aim is to investigate how patients and family members could benefit from using TM, including video consultations and home monitoring, for cardiac rehabilitation. We ask how patients’ health literacy, digital health literacy, health-related quality of life and family support would be affected by a shift to TM.

The primary outcome is the Health Literacy Questionnaire, and secondary outcomes are the eHealth Literacy Questionnaire, European Quality of Life—Five Dimensions Scale, and the Iceland—Family Perceived Support Questionnaire. The sample size is 73 patients in each group. Data will be analysed with ² or Fisher’s exact tests, a t-test or a Wilcoxon signed-rank test, depending on the distribution.

Approval for this trial was obtained from the Danish Data Protection Agency (P-2023-65) and the National Committee on Health Research Ethics (F-23075094). The trial will be conducted in compliance with the Declaration of Helsinki. The trial results—whether positive, neutral or negative—will be submitted for publication. The trial has been registered at ClinicalTrials.gov (NCT06320652).
