Treatment of post-myocardial infarction depressive disorder

Abstract

Both major and minor depressive disorder post-myocardial infarction (MI) are associated with an increased risk of all-cause mortality, cardiac mortality and new cardiovascular events. Post-MI depressive disorder predicts slow recovery and poor quality of life. This review attends to post-MI depressive disorder, its underlying mechanisms and options for and effects of treatment. Evidence has been found for several mechanisms to be involved in the pathophysiology, including hypothalamus–pituitary–adrenal axis activity, immune activity, polyunsaturated fatty acids, serotonin, platelet activation, type D personality and negative health behavior. Five leading randomized controlled trials are discussed, showing safety and efficacy of antidepressive treatment in post-MI patients. Effects on cardiac outcome remain unclear.
