Abstract

Objectives: To evaluate whether late-life depression mediates the association of subclinical cardiovascular disease (CVD) with all-cause mortality. Method: Using data from 3,473 Cardiovascular Health Study participants, the Cox proportional hazards model was used to examine the direct and indirect (via late-life depression) effects of the association between baseline subclinical CVD and all-cause mortality with weights derived from multivariable logistic regression of late-life depression on subclinical CVD. Results: Subclinical CVD led to a higher risk of all-cause mortality (hazard ratio [HR] = 1.51, 95% confidence interval, [CI] = [1.42, 1.94]). Total effect of subclinical CVD on all-cause mortality was decomposed into direct (HR = 1.41, 95% CI = [1.37, 1.58]) and indirect (HR = 1.07, 95% CI = [1.01, 1.23]) effects; 16.3% of the total effect of subclinical CVD on all-cause mortality was mediated by late-life depression. Discussion: Late-life depression accounts for little, if any, of the association between subclinical CVD, a risk factor of all-cause mortality, and all-cause mortality.
