Depression and heart failure: an intricate relationship

Area of Science:

• Cardiology
• Psychiatry
• Clinical Medicine

Background:

• Depression is prevalent in heart failure (HF) patients, linked to poor quality of life, treatment non-adherence, and increased mortality.
• Despite its impact, depression is often underdiagnosed in HF populations.
• The overlapping symptoms of HF and depression complicate timely diagnosis.

Purpose of the Study:

• To review the literature on the association between HF and depression.
• To examine the mechanisms linking HF and depression.
• To identify diagnostic and treatment strategies for depression in HF patients.

Main Methods:

• Targeted literature review.
• Analysis of studies investigating HF-depression association, mechanisms, diagnostic tools, and treatments.
• Evaluation of existing guidelines and evidence for interventions.

Main Results:

• Depression is associated with HF development and progression, mediated by behavioral and pathophysiological factors.
• Diagnostic challenges arise from symptom overlap; specific screening guidelines are lacking.
• Cognitive-behavioral therapy shows promise, and certain antidepressants (SSRIs) appear safe for HF patients.

Conclusions:

• Effective diagnosis and management of depression are vital for improving outcomes in heart failure patients.
• Validated instruments like the Beck Depression Inventory (BDI) and Geriatric Depression Scale (GDS) are recommended for screening.
• Further research is needed to establish clear guidelines and robust evidence for depression treatment in HF.
