Brief Summary

Cardiac events can often result in debilitating and persistent psychological symptoms. A key question involves whether optimal treatment of cardiac-induced posttraumatic stress disorder (PTSD) reduces PTSD symptoms and thereby may offset the risk of recurrent or worsening cardiovascular disease. Cardiac-induced PTSD 1) is prevalent, 2) features symptoms unique to internal ongoing somatic threat, with fears and worries that can be distinguished from PTSD resulting from external causes, 3) is persistent, 4) is associated with negative physical and emotional consequences, and 5) has not been the subject of randomized-controlled treatment trials (RCT). There is preliminary evidence suggesting that patients with cardiac-disease induced PTSD might particularly profit from EMDR. Nevertheless, this possibility has not been tested in cardiac-induced PTSD. Currently, patients with cardiac-induced PTSD are not routinely offered trauma-focused therapies, with a lack of scientific evidence likely being one major reason for this omission. If our proposed RCT shows that EMDR can be an effective treatment for patients with ACS-induced PTSD, EMDR could be routinely implemented as first-line treatment. The RCT outcomes might inform larger trials to test whether poor prognosis in terms of major adverse cardiovascular events can be improved through EMDR in patients with cardiac-induced PTSD.

Outcome Measures

Primary Outcomes (2)

  • Interview-rated posttraumatic stress 3 months Follow-up

    The primary endpoint is the interviewer-rated posttraumatic stress level at three months follow-up (by means of the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5), with a range from 0-160, whereby higher scores mean a worse outcome).

    3 months

  • Interview-rated posttraumatic stress 6 months Follow-up

    The primary endpoint is the interviewer-rated posttraumatic stress level at six months follow-up (by means of the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5), with a range from 0-160, whereby higher scores mean a worse outcome).

Study Arms (2)

Waitlist control group

NO INTERVENTION

The intervention group consists of 30 patients diagnosed with PTSD induced by ACS. No intervention or any other procedure will be conducted during the study period of 36 weeks. Afterwards these subjects will be offered an EMDR therapy as provided in the intervention.

Intervention group

EXPERIMENTAL

The intervention group consists of 30 patients diagnosed with PTSD induced by ACS. Eight individual EMDR sessions lasting for 1 hours will be provided over 8 weeks by licensed EMDR therapists from the German-speaking part of Switzerland. Each EMDR session follows a standardized 8-phase protocol.

Behavioral: EMDR Treatment

Interventions

EMDR TreatmentBEHAVIORAL

Eight individual EMDR sessions lasting for 1 hours will be provided over 8 weeks by licensed EMDR therapists from the German-speaking part of Switzerland. Each EMDR session follows a standardized 8-phase protocol.
