Background: The present study aimed to provide a contribution to the study of a rare disease, amyloid light-chain (AL) cardiac amyloidosis, which is the most common type of systemic amyloidosis. In AL amyloidosis prognosis is determined by cardiac involvement. Although the association between psychological distress (e.g. anxiety and depression) and AL cardiac amyloidosis is documented, very little is known about the psychosocial variables that may mediate the association.Aims: The aim of the study is therefore to examine the potential mediating role of life satisfaction in the relationship between cardiac symptom severity (independent variable) and anxious and depressive symptoms (dependent variables) in AL patients.Method: Forty-three AL amyloidosis patients (57.1% males) with cardiac amyloidosis were administered the Satisfaction with Life Scale, the State-Trait Anxiety Inventory and the Centre for Epidemiological Study–Depression Scale. Clinical variables such as months since cardiac symptom onset and cardiac symptom severity were collected.Results: Findings showed significant relationships between symptom severity and psychological disorders (e.g. anxiety and depression) and these were mediated by life satisfaction.Conclusion: Overall, findings highlight the importance of subjective well-being (e.g. life satisfaction) to reduce anxious and depressive symptoms and to improve general health in AL patients.

Abstract

Background: The present study aimed to provide a contribution to the study of a rare disease, amyloid light-chain (AL) cardiac amyloidosis, which is the most common type of systemic amyloidosis. In AL amyloidosis prognosis is determined by cardiac involvement. Although the association between psychological distress (e.g. anxiety and depression) and AL cardiac amyloidosis is documented, very little is known about the psychosocial variables that may mediate the association.Aims: The aim of the study is therefore to examine the potential mediating role of life satisfaction in the relationship between cardiac symptom severity (independent variable) and anxious and depressive symptoms (dependent variables) in AL patients.Method: Forty-three AL amyloidosis patients (57.1% males) with cardiac amyloidosis were administered the Satisfaction with Life Scale, the State-Trait Anxiety Inventory and the Centre for Epidemiological Study–Depression Scale. Clinical variables such as months since cardiac symptom onset and cardiac symptom severity were collected.Results: Findings showed significant relationships between symptom severity and psychological disorders (e.g. anxiety and depression) and these were mediated by life satisfaction.Conclusion: Overall, findings highlight the importance of subjective well-being (e.g. life satisfaction) to reduce anxious and depressive symptoms and to improve general health in AL patients.
