Mental Health Factors and Lifestyle Adherence After Myocardial Infarction: An Integrative Review.

Abstract

Background: Engaging in healthy lifestyle behaviors following myocardial infarction can improve clinical health outcomes and lower cardiovascular risk factors among patients. However, adhering to a healthy lifestyle after having a myocardial infarction can be challenging, especially for those experiencing poor mental health.

Objective: Based on a conceptual model derived from Lazarus and Folkman's Theory of Stress and Coping and the Health Belief Model, this integrative review focuses on mental health factors associated with adherence to healthy lifestyle behaviors post-myocardial infarction.

Methods: Whittemore and Knafl's integrative review method was used to search and select relevant literature from the EMBASE, PubMed, CINAHL, Scopus, and PsycINFO databases between 2013 and 2023.

Results: A total of 35 articles were included in the review. Based on the Johns Hopkins Nursing Evidence-Based Practice Model criteria, 34 studies were of good quality (B). Mental health factors related to healthy lifestyle behaviors after myocardial infarction included the following: (1) personality factors and coping (eg, neuroticism, agreeableness, and optimism); (2) psychological symptoms (i.e., depression, anxiety, and fear); (3) appraisal (ie, illness perception); (4) health beliefs (ie, susceptibility, severity, benefits, barriers, cues to action, and self-efficacy); and (5) motivation. Social support and demographic characteristics were also related to adherence to healthy lifestyle behaviors.

Conclusions: This review highlights the role of mental health factors in adhering to healthy lifestyle behaviors among persons with myocardial infarction. Comprehensive theoretically based approaches are needed to develop future interventions for promoting healthy lifestyle behaviors in individuals post-myocardial infarction.
