In CHD patients undergoing elective PCI, higher anxiety levels are positively associated with survival and reduce the risk for MACE during the first five years after index PCI. The beneficial effects of anxiety on cardiovascular mortality and morbidity suggest that a differentiated approach to diagnosing and treating anxiety in CHD patients is warranted.
In CHD patients, self-rated depressive symptoms at baseline were negatively linked to survival at 2-year follow-up, but failed to predict mortality 3 years later. Thus, in contrast to other well-established risk factors, the prognostic value of depression for predicting adverse outcome may be temporarily limited. The mechanisms behind this transient effect need further study.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
