“…In contrast, objective parameters of cardiac injury (e.g., troponin T level in ACS) show little correlation with PTSD symptoms [ 45 ]. Various other risk factors for the development of CDI-PTSD symptoms relate to the environment and treatment of the disease (e.g., a hectic hospital admission, treatment complications, statements made by staff, use of benzodiazepines) [ 46 , 47 •], sociodemographic factors (younger age, female sex) [ 44 ], comorbidities (depression, anxiety disorders, ASD) [ 48 ], personality factors (type D, neuroticism, hostility, alexithymia) [ 49 , 50 ], and a patient’s biopsychosocial history (stressful life events, previous heart disease, and other somatic diseases) [ 51 ]. In addition, even patients with suspected ACS that are ultimately ruled out can show PTSD symptoms and have a comparable risk to develop PTSD related to the acute event as patients with confirmed ACS [ 52 ].…”
