Background: There is controversial evidence that a low serum cholesterol level is associated with an increased risk of depression, suicide, and violence. The aim of this study was to identify or exclude any small or infrequent adverse effect of long-term reduction of serum cholesterol with pravastatin sodium on psychological well-being.
There was no significant association between depressive symptoms and fatal or non-fatal cardiovascular events after adjustment for cardiovascular symptoms associated with poorer prognosis. Previously observed associations between depression and cardiovascular mortality may not be causal.
In patients with stable coronary artery disease, persistent psychological distress of at least moderate severity is associated with a substantial increase in CV and all-cause mortality.
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.
