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

Insights
Depression and anxiety symptoms did not predict recurrent coronary heart disease events in patients after myocardial infarction. Disease severity, not psychological state, was associated with adverse cardiac outcomes within 12 months.
Area of Science:
- Cardiology
- Psychiatry
- Clinical Research
Background:
- Myocardial infarction (MI) survivors face risks of recurrent coronary heart disease (CHD) events.
- The role of psychological factors like depression and anxiety in post-MI outcomes requires further investigation.
Purpose of the Study:
- To investigate the association between depression, anxiety, and recurrent CHD events in the 12 months following myocardial infarction.
- To determine if psychological distress predicts adverse cardiac outcomes in MI patients.
Main Methods:
- 288 myocardial infarction patients completed the Beck Depression Inventory and State-Trait Anxiety Inventory during hospitalization.
- Disease severity was assessed using Peel Index score and Killip class.
- Recurrent CHD events (fatal and non-fatal) were tracked for 12 months post-MI.
Main Results:
- 82 patients (28%) experienced recurrent CHD events, including 27 cardiac fatalities.
- Peel Index score significantly differentiated patients with recurrent events (OR 3.00, 95% CI 1.46-6.20).
- Depression (OR 0.97, 95% CI 0.55-1.70) and anxiety (OR 1.00, 95% CI 0.98-1.02) were not associated with recurrent events or disease severity.
Conclusions:
- Depression and anxiety symptoms are not significant predictors of recurrent coronary heart disease events post-myocardial infarction.
- Disease severity indices, such as Peel Index score, are more strongly associated with adverse cardiac outcomes than psychological distress.
- Clinical focus should remain on managing physiological risk factors in post-MI patients.
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.
