The association between the mode of death and depression in patients with stable coronary artery disease (CAD) is far from clear. We investigated the association between depressive symptoms and the mode of death including all-cause mortality, noncardiac death, sudden cardiac death (SCD), and non-SCD in stable CAD patients. Patients with angiographically documented CAD (n = 1,928) underwent a clinical examination including screening for depression symptoms with the Depression Scale (DEPS) and extensive risk profiling at the baseline. The patients were divided into quartiles based on their DEPS score. The patients entered the follow-up (median 6.3 years) during which 49 SCDs (2.5%) and 48 non-SCDs (2.5%) occurred. The incidence of SCD was 1.1% (5 events), 2.0% (9 events), 2.6% (14 events), and 4.4% (21 events) from the lowest to the highest quartile of DEPS. The patients in the highest quartile of DEPS had a fourfold elevated univariate risk (95% confidence interval 1.5 to 10.5; p = 0.006), and after adjustment for traditional risk factors, a 3.2-fold elevated multivariate risk (95% confidence interval 1.2 to 8.9, p = 0.025) for SCD compared with patients in the lowest quartile. DEPS was not associated with non-SCD or noncardiac deaths. Depressive symptoms are associated with an increased risk of SCD independently of clinical risk factors in patients with CAD. The results highlight the importance of screening for depression and emphasize the need for additional interventions to alleviate the depressive symptoms in these patients.
