Factors Associated With Depression and Anxiety for Community-Dwelling Patients With Heart Failure: A Retrospective Cohort Study.

BACKGROUND: Depression and anxiety are common comorbidities in heart failure (HF) and are associated with adverse outcomes including unplanned hospitalization. However, there is insufficient evidence on the factors associated with depression and anxiety for community patients with HF to inform optimal assessment and treatment in this population. AIM: The aim of this study was to examine the prevalence of and factors associated with depression and anxiety in community-dwelling patients with HF. METHODS: A retrospective cohort study of 302 adult patients given a diagnosis of HF referred to United Kingdom's largest specialist cardiac rehabilitation center, from June 2013 to November 2020. Main study outcomes were symptoms of depression using Patient Health Questionnaire-9 and anxiety using the General Anxiety Disorder 7-item scale. Explanatory variables included demographic and clinical characteristics and functional status from the Dartmouth COOP questionnaire: quality of life, pain, level of social activity and daily activities, and being bothered by emotional problems (feelings). Logistic regressions were performed to evaluate the association between demographic and clinical characteristics and depression and anxiety. RESULTS: Of the sample, 26.2% reported depression and 20.2% had anxiety. Higher depression and anxiety were associated with difficulty in performing daily activities (95% confidence interval, 1.11-6.46 and 1.13-8.09, respectively) and being bothered by feelings (95% confidence interval, 4.06-21.77 and 4.25-22.46, respectively). Depression was associated with limitations in social activity (95% confidence interval, 1.06-6.34) and anxiety with distressing pain (95% confidence interval, 1.38-7.23). CONCLUSION: Findings indicate the importance of psychosocial interventions for patients with HF to minimize and manage depression and anxiety. Patients with HF may benefit from interventions targeted to maintain independence, promote participation in social activities, and optimally manage pain.

The Efficacy of Psychological Interventions on Health-Related Quality of Life for Patients With Heart Failure and Depression: A Systematic Review.

BACKGROUND: Depression is prevalent among adults with chronic heart failure (CHF) and is associated with higher rates of morbidity and mortality and higher healthcare costs. OBJECTIVES: The aim of this study was to explore the efficacy of psychological interventions in reducing depression and improving quality of life and clinical outcomes (mortality, hospitalization) among adults with CHF. METHODS: This study performed a systematic review involving searches of 6 databases (MEDLINE, CINAHL, EMBASE, PsycINFO, ASSIA, and SSCI), the Cochrane library, and gray literature, completed in January 2020. Experimental and nonexperimental quantitative studies of psychological interventions for adults with CHF were included. Each study was quality appraised, and key data were extracted and tabled. Overall findings are presented as a narrative synthesis. RESULTS: Nine studies met eligibility. Study authors sampled 757 participants and evaluated 4 psychological interventions: cognitive behavioral therapy alone or combined with exercise, mindfulness-based psychoeducation, coping skills training, and innovative holistic meditation. Cognitive behavioral therapy was significantly associated with improved depression and quality of life, and reduced hospitalization risk. Mindfulness-based psychoeducation, holistic meditation, and coping skills training positively impacted depression and quality of life. Coping skills training also reduced hospitalization and mortality risks. CONCLUSION: Although this review indicates that psychological interventions can be beneficial to adults with CHF who have depression, the overall weight of evidence contains a number of biases. Larger, higher-powered studies are needed to confirm or refute these findings and to better understand how specific intervention and sample characteristics relate to outcomes.
