Circulating cerebral S100B protein is associated with depressive symptoms following myocardial infarction.

Background: Prevalence of depressive symptoms in the post-myocardial infarction (MI) period varies from 8 to 30%. Cerebral damage after MI, caused by transient ischemia, an inflammatory response or both, may contribute to development of post-MI depression. S100B is an established protein marker of cerebral damage.

Treatment of post-myocardial infarction depressive disorder: a randomized, placebo-controlled trial with mirtazapine.

Objective: To examine the antidepressant efficacy of a dual-acting antidepressant (mirtazapine) in patients with post-myocardial infarction (MI) depressive disorder. Antidepressants used in post MI trials with a randomized, double-blind, placebo-controlled design have been restricted to selective serotonin reuptake inhibitors (SSRIs). Antidepressant effects have been limited.
