Stress, anxiety and depression in heart disease patients: A major challenge for cardiac rehabilitation

Abstract

Cardiovascular events and emotional disorders share a common epidemiology, thus suggesting fundamental pathways linking these different diseases. Growing evidence in the literature highlights the influence of psychological determinants in somatic diseases. A patient's socio-economic aspects, personality traits, health behavior and even biological pathways may contribute to the course of cardiovascular disease. Cardiac events often occur suddenly and the episode can be traumatic for people not prepared for such an event. In this review of the literature, the authors tackle the question of psychobiological mechanisms of stress, in a pathophysiological approach to fundamental pathways linking the brain to the heart. Various psychological, biological and genetic arguments are presented in support of the hypothesis that various etiological mechanisms may be involved. The authors finally deal with biological and psychological strategies in a context of cardiovascular disease. Indeed, in this context, cardiac rehabilitation, with its global approach, seems to be a good time to diagnose emotional disorders like anxiety and depression, and to help people to cope with stressful events. In this field, cardiac rehabilitation seems to be a crucial step in order to improve patients' outcomes, by helping them to understand the influence of psychobiological risk factors, and to build strategies in order to manage daily stress.
