BACKGROUND
Globally, cardiovascular disease is the leading cause of death. Cardiovascular mortality can be decreased by participation in cardiac rehabilitation. Researchers are exploring the use of mHealth technology in cardiac rehabilitation.
OBJECTIVE
The aim of this systematic review is to examine the effectiveness of randomized controlled trials that use a mHealth intervention as a part of an outpatient and/or home-based cardiac rehabilitation program on improving physical activity and physical fitness outcomes.
METHODS
For this systematic review, mHealth interventions were limited to text messaging, mobile apps, and use of a mobile phone network for data transmission, used to deliver cardiac rehabilitation program. Using six databases, the search strategy included published English language studies through 2016. Data was extracted independently by two reviewers, and then synthesized.
RESULTS
The initial search yielded 149 articles, of which 15 articles that represented nine studies met inclusion criteria. Articles were published from 2010 to 2016 and came from two continents. The majority (84%) of participants were male. Generally, the participant mean age was late 50s to early 60s. Text messaging was the most frequently used intervention. The results of the physical activity and physical fitness findings were mixed. Effect sizes for intervention as measured by the 6-minute walk test ranged from 0.46 to 0.58 and peak VO2 ranged from 0.03 to 1.35.
CONCLUSIONS
Globally, use of mHealth in outpatient and/or home-based cardiac rehabilitation is being studied with greater attention. However, these studies are limited by geography, gender, and age. Therefore, further research in the area of cardiac rehabilitation and mHealth is recommended, especially in developing countries, among women, and older adults.
