Abstract
PURPOSE: Sudden cardiac death (SCD) in the young is a devastating event occurring in otherwise healthy individuals. Postmortem genetic testing (molecular autopsy) may help identify a cause, though there is potential for uncertainty. We report psychological adaptation to molecular autopsy findings amongst family members after a young SCD. METHODS: First-degree relatives who had experienced a SCD of a young relative and attended a specialized cardiac genetic clinic were invited to complete a cross-sectional, self-report survey comprising a number of validated scales. Clinical, genetic, and family history information was collected from the medical record. RESULTS: Thirty-three individuals from 27 families (response rate 48%) completed a survey (mean age 49 ± 12 years, 49% were mothers of the decedent). Eleven (36%) reported poor adaptation to genetic information, and compared with those with good adaptation, they were more likely to have worse posttraumatic stress symptoms (p = 0.0004) and depression (p = 0.01). Perceived support was lower in those reporting poor adaptation, including social support (p < 0.0001) and perceived support from significant others (p = 0.03), family members (p = 0.001), and friends (p = 0.0002). CONCLUSION: Adaptation to molecular autopsy findings may be difficult for some relatives following a young SCD. Careful pretest genetic counseling and integration of psychological support is needed.
