Hereditary transthyretin amyloidosis (ATTRv) is a genetic, progressive and disabling disease that affects multiple organs and severely compromises the quality of life of patients and their families. A holistic approach is essential, which, in addition to early diagnosis and clinical management, includes psychological support to address the emotional and psychosocial impact of the disease. Although specific interventions for mental well-being are recommended, studies evaluating support tools for patients with ATTRv cardiomyopathy and their caregivers are lacking.
