Abstract

Background: Cardiovascular disease is a leading cause of morbidity worldwide. Cardiac rehabilitation (CR) is a comprehensive secondary prevention approach, with established benefits in reducing morbidity in high-income countries (HICs). The objectives of this review were to summarise what is known about the benefits of CR, including consideration of cost-effectiveness, in addition to rates of CR participation and adherence in high-, as well as low- and middle-income countries (LMICs).

Methods: A literature search of Medline, Excerpta Medica Database (EMBASE), and Google Scholar was conducted for published articles from database inception to October 2013. The search was first directed to identify meta-analyses and reviews reporting on the benefits of CR. Then, the search was focussed to identify articles reporting CR participation and dropout rates. Full-text versions of relevant abstracts were summarised qualitatively.

Results: Based on meta-analysis, CR significantly reduced all-cause mortality by 13%-26%, cardiac mortality by 20%-36%, myocardial re-infarction by 25%-47%, and risk factors. CR is cost-effective in HICs. In LMICs, CR is demonstrated to reduce risk factors, with no studies on mortality or cost-effectiveness. Based on available data, CR participation rates are <50% in the majority of countries, with documented dropout rates up to 56% and 82% in high- and middle-income countries, respectively.

Conclusions: CR is a beneficial intervention for heart patients in high and LMICs, but is underutilised with low participation and adherence rates worldwide. While more research is needed in LMICs, strategies shown to increase participation and program adherence should be implemented.

Keywords: Adherence; Cardiac rehabilitation; Cost-effectiveness; Myocardial infarction; Participation; Secondary prevention.
