Do depression and anxiety predict recurrent coronary events 12 months after myocardial infarction?

Abstract

We examined the association between depression and anxiety and recurrent coronary heart disease events during the first 12 months subsequent to myocardial infarction. The Beck Depression Inventory and the State‐Trait Anxiety Inventory were completed during hospitalization by 288 myocardial infarction patients. Peel Index score and Killip class were used as indices of disease severity. The 12‐month incidence of recurrent coronary heart disease events (fatal and non‐fatal) was determined. Eighty‐two patients experienced recurrent coronary heart disease events, including 27 cardiac fatalities, during follow‐up. Whereas the Peel Index differentiated patients who experienced recurrent events from those who did not (OR 3.00, 95% CI 1.46–6.20), symptoms of depression (OR 0.97, 95% CI 0.55–1.70) and anxiety (OR 1.00, 95% CI 0.98–1.02) were unrelated to outcome. Depression and anxiety did not predict subsequent coronary heart disease events and were not associated with either Peel Index scores or Killip class.
