RESUMEN
Caregivers' psychological well-being is linked to the quality of care provided for familiar with chronic illness. Despite caregivers of cardiac patients present an impaired psychological well-being, less investigated is the psychological well-being of caregivers of individuals with a rare disease such as the Transthyretin Cardiac Amyloidosis (ATTR-CA). Specifically, given that no study explored the well-being of the caregiver and the caregiver-patient relationship, this study aimed to analyze the prevalence of anxiety and depression in ATTR-CA caregivers and if these disorders were associated with patient's and caregiver's characteristics. Fifty-eight dyad caregiver-ATTR-CA patients completed the Hospital Anxiety and Depression Scale and the Network of Relationships Inventory. Moreover, ATTR-CA patients completed the Kansas City Cardiomyopathy Questionnaire, while caregivers completed the Multidimensional Scale of Social Support. Results showed that anxious caregivers (44%) reported higher conflict with patients. They had ATTR-CA relatives with a worse perception of cardiac symptoms and higher anxiety and depression. Depressed caregivers (39%) reported higher conflict with ATTR-CA relatives and lower perceived social support. Caregiver reported a high prevalence of anxiety and depression associated with worse personal relational well-being and to patient's psycho-physical condition. The care of ATTR-CA patient should consider the caregiver well-being.
