Cardiovascular consequences of financial stress: A systematic review and meta-analysis

Background: Cardiovascular diseases (CVD), notably coronary artery disease (CAD) and coronary heart disease (CHD), are predominant contributors to global morbidity and mortality. Financial stress is recognized as a non-traditional risk factor for CVD. The objective of this study is to conduct a systematic review and meta-analysis on the association between financial stress and the incidence of major cardiac outcomes. Methods: A literature search was conducted across multiple databases up until September 20, 2023. Primary studies reporting the association between financial stress and the incidence of CAD, CHD, or major cardiovascular outcomes were included. The quality of the incorporated studies was evaluated using the Newcastle-Ottawa Scale. Statistical analysis was performed using R version 4.3, employing a random-effects model. Results: Out of 2,740 identified studies, seven satisfied the inclusion criteria, displaying a diverse range in design, settings, and participant demographics. A significant association was found between financial stress and major cardiac outcomes, with a combined hazard ratio (HR) of 1.191 (95% CI: 1.00 to 1.47), p<0.001 from five studies. Possible publication bias and variations in definitions and measurements of financial stress were noted among the studies. Conclusion: The available literature substantiates an association between financial stress and the incidence of CAD/CHD or major cardiac outcomes, underscoring an urgent need for standardized definitions and measurements of financial stress. Our findings support the integration of financial stress assessments in patient care and the development of health policies emphasizing economic strains to enhance cardiovascular health outcomes and overall well-being.
