Background Myocardial infarction secondary to spontaneous coronary artery dissection (SCAD) can be traumatic and potentially trigger posttraumatic stress disorder (PTSD). In a large, multicenter, registry‐based cohort, we documented prevalence of lifetime and past‐month SCAD‐induced PTSD, as well as related treatment seeking, and examined a range of health‐relevant correlates of SCAD‐induced PTSD. Methods and Results Patients with SCAD were enrolled in the iSCAD (International SCAD) Registry. At baseline, site investigators completed medical report forms, and patients reported demographics, medical/SCAD history, psychosocial factors (including SCAD‐induced PTSD symptoms), health behaviors, and health status via online questionnaires. Of 1156 registry patients, 859 patients (93.9% women; mean age, 52.3 years) completed questionnaires querying SCAD‐induced PTSD. Nearly 35% (n=298) of patients met diagnostic criteria for probable SCAD‐induced PTSD in their lifetime, and 6.4% (n=55) met criteria for probable past‐month PTSD. Of 811 patients ever reporting any SCAD‐induced PTSD symptoms, 34.8% indicated seeking treatment for this distress. However, 46.0% of the 298 patients with lifetime probable SCAD‐induced PTSD diagnoses reported never receiving trauma‐related treatment. Younger age at first SCAD, fewer years since SCAD, being single, unemployed status, more lifetime trauma, and history of anxiety were associated with greater past‐month PTSD symptom severity in multivariable regression models. Greater past‐month SCAD‐induced PTSD symptoms were associated with greater past‐week sleep disturbance and worse past‐month disease‐specific health status when adjusting for various risk factors. Conclusions Given the high prevalence of SCAD‐induced PTSD symptoms, efforts to support screening for these symptoms and connecting patients experiencing distress with empirically supported treatments are critical next steps.
