Effectiveness of Cardiac Rehabilitation With mHealth Through Smartphone Functionalities: A Systematic Review Protocol

Cardiovascular diseases are the leading cause of mortality worldwide, requiring support to manage symptoms and improve prognosis. Home-based cardiac rehabilitation is a realistic resource for this purpose, but it requires patients' self-management skills in order to change behaviours. Smartphones are considered mHealth technology (mobile technological resources in healthcare) and have the potential to provide modalities for delivery of cardiac rehabilitation. This systematic review aims to examine these modalities and identify those that are most effective for improving exercise capacity, quality of life, and patient compliance. Randomized controlled trials (1994 to 2022) performed with adults with coronary artery disease (post-myocardial infarction, angina, post-coronary artery bypass graft surgery) or heart failure eligible for home-based cardiac rehabilitation (mHealth) will be selected. Studies published in English, Spanish, or Portuguese that compare rehabilitation-specific mobile apps or smartphone-based features with conventional cardiac rehabilitation will be included. Searches will be conducted in MEDLINE, CENTRAL, EMBASE, LILACS, PEDro, grey literature, and ongoing or recently completed studies. Data and risk of bias will be assessed, and if appropriate, a meta-analysis will be carried out.
