Association between depression, antidepressant use, and the incidence of atherosclerotic cardiovascular diseases

Abstract

ObjectiveTo examine the association between depression, the use of antidepressants, and atherosclerotic cardiovascular disease (ASCVD). MethodsThe South Korean national claims data was used. Among a nationally representative population, 273,656 subjects who had been diagnosed with depression and prescribed antidepressants (“DEP with antidepressants”) and 78,851 subjects who had been diagnosed with depression but not prescribed antidepressants (“DEP without antidepressants”) were identified to be eligible. Healthy controls (HCs) were 1:1 matched with DEP with antidepressants group for age and sex. We followed up on the occurrence of ASCVD including ischemic heart diseases and ischemic stroke. ResultsThe risk of ASCVD was increased in the DEP with antidepressants group and decreased in the DEP without antidepressants group compared to HCs. Among those under antidepressants, tricyclic antidepressant users showed the highest risk of ASCVD compared to HCs. Among young adults, the risk of ASCVD was increased in both groups. ConclusionThe risk of ASCVD increased in depression patients taking antidepressants, while it decreased in depression patients not taking antidepressants. However, the relationship showed differences according to drug class and age group.
