Left Ventricular Dysfunction and Depression in Hospitalized Patients with Heart Failure

Area of Science:

• Cardiology
• Psychiatry
• Health Services Research

Background:

• Heart failure (HF) is a complex condition often accompanied by psychological distress.
• Depression is a common comorbidity in HF patients, impacting quality of life and clinical outcomes.
• The relationship between cardiac dysfunction severity and depression in HF requires further investigation.

Purpose of the Study:

• To determine if left ventricular systolic dysfunction severity is associated with depression in hospitalized heart failure patients.
• To identify other independent correlates of depression in this patient population.

Main Methods:

• A cohort of 400 hospitalized heart failure patients was analyzed.
• Left ventricular ejection fraction and medical data were extracted from records.
• Depression and psychosocial factors were assessed via interviews and questionnaires.
• Statistical models, including proportional odds and analysis of covariance, were employed.

Main Results:

• No significant association was found between left ventricular ejection fraction and depression diagnosis or severity.
• Higher odds of depression were observed in African American patients.
• Elevated levels of anxiety and perceived stress were independently associated with increased depression risk.
• Factors like sex and age did not show consistent associations with depression in this cohort.

Conclusions:

• The severity of left ventricular systolic dysfunction does not correlate with depression in heart failure patients.
• Depression in heart failure is more strongly linked to demographic factors (e.g., race) and psychosocial stressors (anxiety, stress).
• These findings highlight the importance of screening for and managing anxiety and stress in heart failure patients, particularly within specific demographic groups.
