Psychological Sequelae After Sudden Cardiac Death in the Patient and His Relatives (TEMPO)

This study will evaluate and describe the occurrence of Acute traumatic stress and persistence of Post Traumatic Stress Disorder (PTSD) after resuscitated sudden cardiac death (SCD) in patient and relatives present during the event. The population will be composed of 40 patients: 20 with resuscitated SCD and 20 relatives. Two interviews will be performed by a psychologist within one week after resuscitated SCD and at month 3. Questionnaire Stanford Acute Stress Reaction Questionnaire (SASRQ), Life Events Checklist for Diagnostic and Statistical Manual of Mental Disorders (DSM-5) (LEC-5) and Posttraumatic Stress Disorder Checklist for DSM-5 (PCL-5) will be filled during these interviews.

In spite of therapeutic advances, sudden cardiac death (SCD) remains a frequent (60000/year in France) and often fatal disease (5% survival). Because it is by definition unexpected, the psychological impact on resuscitated patients and on relatives may be important. However little studies have evaluated it. Patients who later develop PTSD, generally have acute stress disorder. In patients with resuscitated sudden cardiac death, acute psychological distress is frequent and PTSD was identified in 40% of patients. Concerning relatives, Haywood (2018) call them the "forgotten patients" to emphasize the absence of recognition of his psychological trauma. PTSD was more frequent in people who were witness of the SCD vs those who were not there. Hofland et al (2018) showed that people present during resuscitation maneuvers had more acute stress than others. This study will evaluate acute stress disorder with SASRQ scale in patients with resuscitated SCD and their relative just after the event. At 3 months, presence of PTSD will be evaluated with PCL-5 and LEC-5 in patients and their relatives.

During an interview with a trained psychologist, the presence of acute stress will be assessed by the SASRQ test within one week of the occurrence of a sudden recovered death. The diagnosis of acute post-traumatic stress disorder is made according to the presence of at least three dissociative symptoms out of five, and other symptoms of re-experiencing, avoidance or marked anxiety or hypervigilance. Each symptom is thus evaluated dichotomously. A symptom is present if the intensity of the response is 3 or more (0 "from 0 to 2" and 1 "from 3 to 5").

This questionnaire will be completed during an interview with a psychologist trained in the protocol, 3 months after the sudden death. The PCL-5 is a 20-item self-report questionnaire that assesses the 20 symptoms of PTSD according to the DSM-V. It is associated with the LEC-5 questionnaire. The self-reported scale uses ratings of "0 to 4" to assess each of the symptoms. A threshold of 38 on the PCL-5 seems reasonable to suggest the presence of PTSD.

The percentage of patients and/or relatives is determined using the LEC-5 included in the PCL-5 questionnaire
