In patients with cardiovascular disease (CVD), depression is common, persistent, and associated with worse health-related quality of life, recurrent cardiac events, and mortality. Both physiological and behavioral factors-including endothelial dysfunction, platelet abnormalities, inflammation, autonomic nervous system dysfunction, and reduced engagement in health-promoting activities-may link depression with adverse cardiac outcomes. Because of the potential impact of depression on quality of life and cardiac outcomes, the American Heart Association has recommended routine depression screening of all cardiac patients with the 2- and 9-item Patient Health Questionnaires. However, despite the availability of these easy-to-use screening tools and effective treatments, depression is underrecognized and undertreated in patients with CVD. In this paper, we review the literature on epidemiology, phenomenology, comorbid conditions, and risk factors for depression in cardiac disease. We outline the associations between depression and cardiac outcomes, as well as the mechanisms that may mediate these links. Finally, we discuss the evidence for and against routine depression screening in patients with CVD and make specific recommendations for when and how to assess for depression in this high-risk population.

Readmissions to the hospital are common and costly, often resulting from poor care coordination. Despite increased attention given to improving the quality and safety of care transitions, little is known about patient and provider perspectives of the transitional care needs of rehospitalized Veterans. As part of a larger quality improvement initiative to reduce hospital readmissions, the authors conducted semi-structured interviews with 25 patients and 14 of their interdisciplinary health care providers to better understand their perspectives of the transitional care needs and challenges faced by rehospitalized Veterans. Patients identified 3 common themes that led to rehospitalization: (1) knowledge gaps and deferred power; (2) difficulties navigating the health care system; and (3) complex psychiatric and social needs. Providers identified different themes that led to rehospitalization: (1) substance abuse and mental illness; (2) lack of social or financial support and homelessness; (3) premature discharge and poor communication; and (4) nonadherence with follow-up. Results underscore that rehospitalized Veterans have a complex overlapping profile of real and perceived physical, mental, and social needs. A paradigm of disempowerment and deferred responsibility appears to exist between patients and providers that contributes to ineffective care transitions, resulting in readmissions. These results highlight the cultural constraints on systems of care and suggest that process improvements should focus on increasing the sense of partnership between patients and providers, while simultaneously creating a culture of empowerment, ownership, and engagement, to achieve success in reducing hospital readmissions.
