Peer-support interventions and related outcomes in patients with myocardial infarction: A systematic review

Myocardial infarction (MI) is one of the main causes of disability and death worldwide. Peer-support can ameliorate the psychological and physical morbidities associated with heart diseases. The aim of this study was to determine whether peer-support interventions could improve the psychological and behavioral health outcomes commonly experienced by MI patients.

In this systematic review, international databases (PubMed, Web of Science, and Scopus) were searched to gather related publications up to March 2023. Eligible papers were those addressing the outcomes of peer-support interventions in individuals with a history of MI.

Twelve clinical trials published in English with a Jadad score of 3 or 4 (out of 5) were included in the final review. These studies used four approaches to deliver peer-support interventions: face-to-face, telephone-based, educational videos, and group discussion. The results showed that peer-support could have a positive effect on depression, anxiety, quality of life, sexual performance, self-care, and medication adherence.

Considering the serious impacts of MI on life, these patients need empowerment training. Peer-support can be used as a complementary supportive method to reduce MI patients' psychological complications and improve their behavioral outcomes.
