Abstract
Background:
Despite optimal medical treatment, many heart failure (HF) patients continue to show a high prevalence of symptoms, which contributes to a high morbidity and poor health-related quality of life (HRQL). Mindfulness meditation may be effective in improving the quality of life in these patients.
Objective:
A systematic review was conducted to evaluate if mindfulness meditation programs are effective in promoting and improving the quality of life in patients with heart failure.
Methods:
The PubMed (MEDLINE), Cumulative Index of Nursing and Allied Health (CINAHL), LILACS, Cochrane Library, and Scopus databases were searched between October and November of 2019. Articles were selected if they evaluated mindfulness intervention, with an experimental or quasi-experimental design, in adults with heart failure and measured health-related quality of life.
Results:
This systematic review identified 108 studies through database searches. After applying the inclusion and exclusion criteria, a total of three studies were considered qualified. These studies took place in the Netherlands, the USA, and Brazil, and occurred between 2005 and 2015. Sample sizes varied from 19 to 215, and the average range of participants within each study varied from 43.2 to 75.4 years. Compared to control programs, mindfulness-based meditation programs improved the quality of life in two studies (p= 0.041 and p=0.03).
Conclusion:
Mindfulness-based meditation programs improved the quality of life in patients with HF. Therefore, there is limited data to strengthen this recommendation to this population, and future research is warranted in order to present consistency in the intervention protocols.
