Summary

This study found that fright and positive affect predict intrusive thoughts after myocardial infarction. Negative affect in hospital predicts physiological arousal and avoidance symptoms of post-traumatic stress disorder (PTSD).

Area of Science:

  • Cardiology
  • Psychiatry
  • Psychology

Background:

  • Myocardial infarction (MI) can trigger psychological distress.
  • Post-traumatic stress disorder (PTSD) symptoms can emerge after cardiac events.
  • Understanding PTSD predictors in MI patients is crucial for timely intervention.

Purpose of the Study:

  • To identify correlates and predictors of PTSD symptoms in myocardial infarction patients.
  • To assess PTSD symptoms during hospitalization and 3 months post-MI.
  • To establish a risk profile for MI-related PTSD.

Main Methods:

  • A longitudinal study of consecutive MI patients.
  • 39 patients completed in-hospital and 3-month follow-up questionnaires.
  • Assessed PTSD symptoms, mood, and immediate cognitive/emotional reactions.

Main Results:

  • PTSD symptom associations were stronger at 3-month follow-up.
  • Fright and positive affect predicted intrusive thoughts (R(2)=0.262, R(2)=0.112).
  • Negative affect predicted physiological arousal and avoidance (R(2)=0.174, R(2)=0.203).

Conclusions:

  • Early intervention for PTSD post-MI may not be beneficial and could be detrimental.
  • Formal PTSD treatment may be effective several months after hospital discharge.
  • Identifying at-risk patients is essential for effective management of MI-related PTSD.
