This theoretical review suggests that early interventions targeting chronic stress pathways could potentially delay or prevent the onset of both depression and cardiovascular disease.
INTRODUCTION: Although the association between depression and cardiovascular disease (CVD) is well documented, the underlying mechanisms for this relationship remain unclear. In this paper, we present three possible models which account for the comorbidity between depression and cardiovascular disease. MODELS: The first model outlines depression as a risk factor for CVD and the second model presents CVD as a risk factor for depression. The third model proposes a common underlying pathway related to the effects of chronic stress on the body in manifesting as depression or cardiovascular disease. CONCLUSIONS: If the proposed model holds true, it may be possible that an intervention initiated before overt manifestations of CVD or depression become apparent, may delay or prevent the onset of these serious clinical entities.
