Depressive symptoms and 10-year risk for cardiovascular morbidity and mortality

Abstract Objectives. Depression is associated with increased physical morbidity and overall mortality. As less is known about how much depression increases the 10-year risk for fatal and nonfatal cardiovascular (CV) events, we evaluated the cross-sectional risk with two well-characterized risk functions measuring CV mortality and total CV event risk. Methods. The prevalence of increased depressive symptoms was measured with the Beck Depression Inventory (BDI), and the SCORE and Framingham risk functions were calculated in a middle-aged population-based sample (N=923). For metabolic syndrome (MetS), the modified National Cholesterol Education Program – Adult Treatment Panel III criteria were employed. Results. Depressive symptoms were associated with increased CV mortality and morbidity risk in men: OR for SCORE 2.9; 95%CI 1.4–5.7 and OR for Framingham function 2.2 (95%CI 1.1–4.2). In women, the corresponding figures were 1.4 (95%CI 0.3–6.9) and 1.3 (95%CI 0.7–2.6). The BDI scores showed significant correlations with SCORE (r=0.18 for men, P < 0.001; and r=0.14 for women, P=0.002), and Framingham function (for men r=0.16, P < 0.001; and for women r=0.13, P=0.005). Conclusions. Our results suggest that screening and effective treatment of depression are important in the primary and secondary prevention of cardiovascular events, especially in males.
