Background: Research on the relationship between chest pain and depression risk in patients with or without coronary heart disease (CHD) is limited.
Methods: This cross-sectional study includes adults in the National Health and Nutrition Examination Survey (NHANES) from 2005 to 2018. The diagnoses of chest pain and CHD were based on self-reports from participants, while depressive symptoms were assessed using the Patient Health Questionnaire (PHQ-9). The study employs logistic regression, subgroup analysis, and sensitivity analysis to explore the association between chest pain and depressive symptoms, taking into account the influence of CHD.
Results: The study included 15,048 adults aged 20 years or older, with an average age of 59.6 ± 12.1 years, and 51.6 % were male. After adjusting for covariates, a significant difference in the association between chest pain and the risk of depression was observed between the non-CHD group and CHD group (non-CHD group: OR = 2.43, 95 % CI: 2.13-2.78; CHD group: OR = 1.2, 95 % CI: 0.72-1.98). Furthermore, subgroup analysis revealed an interaction between CHD status and chest pain that may reduce the prevalence of depression (P-value for interaction = 0.004). Sensitivity analysis confirmed the stability of the results.
Conclusion: Our findings suggest that the presence of CHD may influence the relationship between chest pain and depression risk among American adults. His conclusion requires further validation through randomized controlled trials.
