Depression and poor outcome after an acute coronary event: Clarification of risk periods and mechanisms.
Lifetime depression and depression around the time of an acute coronary syndrome event have been associated with poor cardiac outcomes. Our study sought to examine the persistence of this association, especially given modern cardiac medicine's successes. ⋯ Lifetime depression may increase the risk of depression around the time of an acute coronary syndrome but not influence cardiac outcomes. We suggest that poor sleep quality may be causal or indicate high anxiety/neuroticism, which increases risk to depression and contributes to poor cardiac outcomes rather than depression being the primary causal factor.
