Prevalence of psychiatric disorders in patients with ischemic heart disease: A systematic review and meta-analysis

Abstract

Background: Ischemic heart disease and psychiatric disorders are among the leading causes of morbidity and mortality. Plans for providing basic health services to community members require knowledge of the current state. Therefore, the aim of this study was to systematically review the literature to estimate the prevalence of psychiatric disorders among patients with ischemic heart disease. Materials and Methods: In this study, PubMed, Embase, and Web of Science were systematically searched to find studies published before June 6, 2021. The systematic review included all original articles on the prevalence of psychiatric disorders among patients with ischemic heart disease. Two independent researchers evaluated the quality of studies, using the Joanna Briggs Institute questionnaire. All analyses were performed in Stata/MP version 16. A random-effects model was used for data analysis. Results: Of 1672 studies initially identified, 13 studies were included in our meta-analysis, with a total of 2233 participants. The overall prevalence of psychiatric disorders was estimated at 46.85% (95% confidence interval [CI]: 36.08–57.62; I2 = 100%; P < 0.001 for heterogeneity). The most common disorder was depression (27.80%; 95% CI: 18.27–37.34; I2 = 99.99%; P < 0.001 for heterogeneity). Based on the results, the prevalence of psychiatric disorders had increased by 25.55% from 2000 to 2021 compared to1984–2000. Conclusion: The prevalence of psychiatric diseases in people with ischemic heart disease is high and increases over time. It is recommended that preventive measures be taken worldwide.
