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.
