Abstract

Abstract: Background: Psychosocial burden is associated with increased risk of cardiovascular (CV) events in patients with stable coronary heart disease (CHD). The underlying mechanisms linking psychosocial burden and CHD are unclear and might be explained by studying biomarkers known to be associated with CV risk. Methods: 15, 608 patients in the STABILITY trial completed a questionnaire on to what extent they were feeling down, had loss of interest, experienced financial stress and if they were living alone. Levels of high-sensitivity (hs) C-reactive protein (hs-CRP), interleukin-6 (IL-6), hs-troponin T (hs-TnT) and N-terminal pro-B type natriuretic peptide (NT-proBNP) were assessed at baseline. Associations between levels of psychosocial burden (sometimes, often/always vs. never/rarely) and biomarkers were evaluated in a linear model where geometric mean ratio of the log-transformed biomarker were calculated. Results: Adjusted associations (age, gender and established CV risk factors) are presented in the table. Conclusion: Psychosocial burden in patients with stable CHD was independently associated with elevated biomarkers. The underlying association is likely to be complex and involve multiple pathways.
