The Impact of Post-Myocardial Infarction (MI) Depression on Cardiovascular-Related Hospitalizations

Abstract

Routine depression screening and subsequent treatment in post-myocardial infarction (MI) patients may lead to improved cardiac outcomes. However, screening for depression is not a standard of post-MI care. Though the American Heart Association (AHA) published an advisory recommending routine depression screening in post-MI patients, there is conflicting evidence on the benefit that routine depression screening has on cardiovascular outcomes. The purpose of this study is to compare the occurrence of cardiovascular-related readmissions in post-MI patients diagnosed with depression versus post-MI patients not diagnosed with depression. This retrospective cohort study analyzed the incidence of cardiovascular-related readmissions and mortality in adult post-MI patients diagnosed with depression within 1 year compared to those not diagnosed with depression within a year. Those diagnosed with depression were more likely to experience a subsequent cardiovascular-related hospitalization within 2 years of MI than those not diagnosed with depression (52.6% vs 28.7%; odds ratio [OR], 3.19; 95% CI 2.33-4.38). There was no difference between groups in the incidence of in-hospital mortality.
