Objective

To determine the association between PTSD symptoms due to prior trauma and prior trauma type with PTSD symptoms after suspected acute coronary syndrome (ACS).

Method

A consecutive sample of patients presenting to the emergency department (ED) for suspected ACS were surveyed. Logistic regression was used to estimate the odds of elevated ACS-related PTSD symptoms [PCL-S ≥ 33] at 1-month associated with PTSD symptoms due to prior trauma and prior trauma type at the time of suspected ACS, adjusting for demographics, comorbidities, depression, and etiology of ACS symptoms.

Results

Of 984 patients, 81.6% reported ≥1 prior trauma type and 22.5% reported PTSD symptoms due to prior trauma at the time of suspected ACS. One month later, 18.0% had ACS-related PTSD symptoms. Patients with versus without PTSD symptoms due to prior trauma at the time of the suspected ACS had increased odds of ACS-related PTSD symptoms one month later (42.1% vs 9.9%; aOR 4.49, 95% CI:3.05-6.60; p < .001). Prior life-threatening illness was the only trauma type significantly associated with ACS-related PTSD symptoms (aOR 1.57, 95% CI:1.03-2.39; p = .04).

Conclusions

PTSD symptoms from prior trauma and history of life-threatening medical illness at the time of suspected ACS increased risk of ACS-related PTSD symptoms one month later.
