Two studies are discussed that were carried out across several hospitals in the Netherlands that will help us to understand the intriguing relation between depression and heart disease. 2,466 heart attack patients were assessed on depression and clinical characteristics during hospitalization and followed for more than 2.5 years. The results of these two studies show that it is important to distinguish between depression subtypes based on whether they are first-ever or recurrent, as these subtypes differ in cardiotoxicity and response to antidepressive treatment.
Moreover, those depressions may differ in symptomatology, and some symptoms may be more cardiotoxic than others. These two studies indicate that especially somatic and incident depressions are associated with poor prognosis in cardiac patients, which is very different from the 'typical' psychiatric depression that is usually characterised by cognitive and recurrent depressive symtoms. These results could lead to new treatment strategies to prevent future cardiac events, which may be quite different than those described in current guidelines for depression in the general population and could lead to more specific and effective treatments.
