Depression, anxiety, and vital exhaustion are associated with pro-coagulant markers in depressed patients with coronary artery disease - A cross sectional and prospective secondary analysis of the SPIRR-CAD trial.

A hyper-coagulant state is a biological mechanism that triggers cardiac events in patients with coronary artery disease (CAD). Depressive symptoms and anxiety predict an unfavourable course of CAD. The SPIRR-CAD-RCT examined the effects of a psychological intervention and provided the opportunity to explore cross-sectional associations between indices of psychological strain and coagulation parameters, as well as prospective changes in depression scores and coagulation parameters. In this secondary analysis, we investigated 253 CAD patients (194 male; age m 58.9, SD 8.3 yrs.) with mild to moderate depression (≥8 on the HADS-D) at baseline and at follow-up 18 months later: TF, fibrinogen, D-dimer, VWF, FVII and PAI-1 and the course of depression (HAM-D), vital exhaustion (VE) and anxiety scores (HADS-A) were examined by ANOVA in the total and younger age groups (≤ 60). HAM-D at baseline was correlated with TF (corr. R This is the first study to show an association between TF and depression. Coagulation parameters as potential mediators of CAD progression correlated cross-sectionally with depression and anxiety and prospectively with VE. Further studies should replicate these correlations in depressed and non-depressed CAD patients. 76240576; clinicaltrials.gov.
