Frequency and predictors of depression in congestive heart failure

Comorbid depression among adults with heart failure in Ethiopia: a hospital-based cross-sectional study

BACKGROUND

Depression is a common comorbidity in adults with heart failure. It is associated with poor clinical outcomes, including decreased health-related quality of life and increased morbidity and mortality. There is a lack of data concerning the extent of this issue in Ethiopia. Consequently, this study aimed to assess the prevalence of comorbid depression and associated factors among adults living with heart failure in Ethiopia.

METHODS

A hospital-based cross-sectional study was conducted at the cardiac outpatient clinics of two selected specialist public hospitals in Addis Ababa, Ethiopia: St. Paul's Hospital Millennium Medical College and St. Peter Specialized Hospital. An interviewer-administered questionnaire was used to collect data from 383 adults with heart failure who attended the clinics and met the inclusion criteria. Depression was measured using the Patient Health Questionnaire (PHQ-9). A binary logistic regression model was fitted to identify factors associated with depression. All statistical analyses were conducted using STATA version 17 software.

RESULTS

The mean age of the participants was 55 years. On average, participants had moderate depression, as indicated by the mean PHQ-9 score of 11.02 ± 6.14, and 217 (56.6%, 95%CI 51.53-61.68) had comorbid depression. Significant associations with depression were observed among participants who were female (AOR: 2.31, 95%CI:1.30-4.08), had comorbid diabetes mellitus (AOR: 3.16, 95%CI: 1.47-6.82), were classified as New York Heart Association (NYHA) class IV (AOR: 3.59, 95%CI: 1.05-12.30), reported poor levels of social support (AOR: 6.04, 95%CI: 2.97-12.32), and took more than five medications per day (AOR: 5.26, 95%CI: 2.72-10.18).

CONCLUSIONS

This study indicates that over half of all adults with heart failure in Ethiopia have comorbid depression, influenced by several factors. The findings have significant implications in terms of treatment outcomes and quality of life. More research in the area, including interventional and qualitative studies, and consideration of multifaceted approaches, such as psychosocial interventions, are needed to reduce the burden of comorbid depression in this population.

Heart failure symptom burden, dietary intake, and inflammation: An integrative review of the literature

Heart failure (HF) is characterized by high symptom burden including, but not limited to fatigue, dyspnea, and edema. Up to 21.5% of HF patients experience significant depressive symptoms, much higher than 7.1% in adults without HF. Diet, metabolites, and other inflammatory mechanisms have gained notable attention in recent studies for contributions to symptoms in HF. Symptoms for black adults (B/As) with HF are often influenced by lifestyle factors, which may influence their higher mortality rates; few studies address these factors. Distinguishing the links between key elements with diet, inflammation, and symptoms may bring clarity for new dietary strategies in HF clinical care. The purpose of this integrative review is to examine the existing literature regarding relationships among physiologic pathways in HF along with physical and emotional symptoms in the context of inflammation, dietary intake, tumor necrosis factor-alpha (TNF-α), a biomarker of inflammation, and trimethylamine-N-Oxide (TMAO). Based on available evidence, inflammation may be a key link between physical symptoms, diet, depression, TMAO, and TNF-α in persons with HF and warrants further examination to clarify pathological links to solidify evidence for better guidance with dietary modifications. The literature reviewed in this study demonstrates that more work is needed to examine dietary planning, social support, and differences between men and women in the B/A community. Results of this literature review call attention to the essential, personalized care needs related to symptom monitoring and dietary planning which is expected to decrease symptom burden in the HF population.

Global prevalence of depression, anxiety, and stress in cardiac patients: A systematic review and meta-analysis

BACKGROUND

Cardiovascular disease is one of the most common chronic and life-threatening diseases. Due to the changes made in the normal living conditions of people after suffering from cardiovascular diseases, the appearance of symptoms of depression, anxiety, and stress is common among these patients. The results of the studies show the different prevalence of these disorders, so this study aimed to standardize the global prevalence of depression, anxiety, and stress in Cardiac patients by a systematic review and meta-analysis approach.

METHODS

The present systematic review and meta-analysis were conducted from 2000 to 2022. National and international databases were considered to retrieve related studies, including SID, Magiran, Scopus, Embase, PubMed, and Web of Science (WoS). Joanna Briggs Institute (JBI) checklist was used to evaluate studies qualitatively. Heterogeneity between studies was assessed by I2 index, and data analysis was performed in Comprehensive Meta-Analysis software.

RESULTS

After reviewing the retrieved studies, finally 68 studies on the prevalence of depression with a sample size of 110,219, 36 studies on the prevalence of anxiety with a sample size of 72,374 and 5 studies on the prevalence of stress with a sample size of 533 considered for the meta-analysis. Based on the results of the Meta-Analysis, the overall estimation of the prevalence of depression was 31.3 % (95 % confidence interval: 25.4/0.38 %), anxiety prevalence; 32.9 % (95 % confidence interval: 21.9-46.6 %) and stress prevalence was 57.7 % (95 % confidence interval: 45.3-3.3 %).

CONCLUSION

The result of the present study shows the high prevalence rate of depression, anxiety, and stress in cardiac patients. Therefore, it is recommended that health professionals and policymakers pay more attention to preventing and controlling these disorders.

Factors Associated With Depression and Anxiety for Community-Dwelling Patients With Heart Failure

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.

Healthcare use during COVID-19 and the effect on psychological distress in patients with chronic cardiopulmonary disorders in the Netherlands: a cross-sectional study

OBJECTIVES

The COVID-19 pandemic caused a massive shift in the focus of healthcare. Such changes could have affected health status and mental health in vulnerable patient groups. We aimed to investigate whether patients with chronic pulmonary and cardiac diseases had experienced high levels of psychological distress during the COVID-19 pandemic in the Netherlands.

DESIGN

A cross-sectional study.

SETTING

COVID-19 pandemic-related changes in healthcare use, health status and psychological distress were investigated among patients with chronic obstructive pulmonary disease (COPD), pulmonary fibrosis (PF) and congestive heart failure (CHF), using an online nationwide survey.

PARTICIPANTS

680 patients completed the survey. COPD was the most often reported diagnosis 334 (49%), followed by congestive heart failure 219 (32%) and PF 44 (7%). There were 79 (12%) patients with primary diagnosis 'other' than chronic cardiopulmonary disease, who also completed this survey.

INTERVENTIONS

Psychological distress was assessed via the DASS-21 score (Depression Anxiety Stress Scale). Moreover, specific worries and anxieties regarding COVID-19 were explored.

RESULTS

The frequency of contact with healthcare professionals changed in 52%. Changes in treatment were reported in 52%. Deterioration in health status was self-reported in 39%. Moderate to extremely severe levels of depression, anxiety and stress was observed in 25.8%, 28.5% and 14%, respectively. Over 70% reported specific worries and anxieties, such as about their own health and fear of being alone. Both the deterioration in health status and increased levels of anxiety were significantly (p<0.001, p<0.006) associated with changes in treatment. Exploratory analyses indicated that lack of social support may further increase anxiety.

CONCLUSION

Healthcare use changed during the COVID-19 pandemic in the Netherlands. It was associated with a decrease in health status, and increased psychological stress among patients with chronic cardiopulmonary disorders. Provision of healthcare should be more sensitive to the mental health needs of these patients during subsequent COVID-19 waves.

Sedentary behavior and health outcomes in patients with heart failure: a systematic review and meta-analysis

A better understanding of the association between sedentary behavior and heart failure is essential for the development of interventions to improve patients' outcomes. Therefore, a systematic review was conducted to determine the association between sedentary behavior and all-cause mortality, health-related quality of life, and depression in heart failure patients. We searched Web of Science, PubMed, Embase, and Cochrane Library and articles in references on 7 May 2021. The search results were limited to articles on heart failure patients over the age of 18, observational studies investigating the association between sedentary behavior and heart failure, and studies reporting one or more outcomes of interest. Two reviewers independently screened the literature and extracted data. Strengthening the Reporting of Observational Studies in Epidemiology was used to assess the quality of articles. Nine observational studies were included, of which, four were of high quality. Four cohort studies indicated that sedentary behavior was significantly associated with increased all-cause mortality (hazard ratio: 1.97; 95% confidence interval: 1.60 to 2.44; I² = 38.9%). In addition, subgroup analysis based on geographical regions was conducted (hazard ratio: 1.82; 95% confidence interval: 1.46 to 2.29; I² = 0%). Sedentary behavior was associated with worse health-related quality of life in patients with heart failure, and the regression coefficients ranged from 0.004 to 0.033 (95% confidence interval: 0.0004 to 0.055). Although sedentary behavior was associated with increased all-cause mortality and worse quality of life in patients with heart failure, further studies are needed to determine whether this association is causal.

The prevalence of depression, stress and anxiety symptoms in patients with chronic heart failure

Background

Mental health illnesses are associated with frequent hospitalisation and an increased risk of all-cause mortality. Despite the high prevalence of depression in patients with chronic heart failure (CHF), there is a paucity of data on this subject from low and middle-income countries (LMIC). The aim of this study was to determine the prevalence of depression, anxiety, and stress symptoms in patients attending a dedicated CHF clinic.

Methods

A prospective study was conducted at an outpatient heart failure clinic in a tertiary academic centre. The study participants completed a Depression, Anxiety and Stress (DASS-21) questionnaire to screen for the presence and severity of depression, anxiety and stress symptoms. Furthermore, the Minnesota Living with Heart Failure Questionnaire (MLHFQ) was completed and used to evaluate the impact of CHF on health-related quality of life (QoL). Descriptive statistics were used to describe patients' characteristics and logistic regression analysis to identify predictors of symptoms of depression.

Results

The study population comprised of 103 patients, predominantly female (62.1%) with a median age of 53 (interquartile range 38–61) years. Symptoms of depression were reported by 52.4%, with 11.6% reporting symptoms suggestive of extremely severe depression. Anxiety was diagnosed in 53.4% of patients and extremely severe anxiety was reported by 18.4% of patients. Fifty patients were classified as stressed, and only 7.7% had extremely severe stress. More than half of the patients (54.4%) were in New York Heart Association functional class I. The mean left ventricular ejection fraction in the entire cohort was 30% (SD =  ± 11.1%). In the multivariable logistic regression model, the MLHFQ score [odds ratio (OR) 1.04, 95% CI:1.02–1.06, p = 0.001] and the six-minute walk test [OR 0.99, 95% CI: 0.98–0.99, p = 0.014] were identified as independent predictors of depression.

Conclusion

Depression and anxiety symptoms were found in over half of patients attending the CHF clinic. We recommend that mental health screening should be routinely performed in patients with CHF. Prospective, adequately powered, multicentre studies from LMIC investigating the impact of depression, anxiety and stress on CHF outcomes such as health-related QoL, hospitalisation and mortality are required.

Drug repositioning for psychiatric and neurological disorders through a network medicine approach

Psychiatric and neurological disorders (PNDs) affect millions worldwide and only a few drugs achieve complete therapeutic success in the treatment of these disorders. Due to the high cost of developing novel drugs, drug repositioning represents a promising alternative method of treatment. In this manuscript, we used a network medicine approach to investigate the molecular characteristics of PNDs and identify novel drug candidates for repositioning. Using IBM Watson for Drug Discovery, a powerful machine learning text-mining application, we built knowledge networks containing connections between PNDs and genes or drugs mentioned in the scientific literature published in the past 50 years. This approach revealed several drugs that target key PND-related genes, which have never been used to treat these disorders to date. We validate our framework by detecting drugs that have been undergoing clinical trial for treating some of the PNDs, but have no published results in their support. Our data provides comprehensive insights into the molecular pathology of PNDs and offers promising drug repositioning candidates for follow-up trials.

Effects of a structured heart failure program on quality of life and frequency of hospital admission in Saudi Arabia

Objectives:

To compare the quality of life (QOL) and frequency of hospital admission (FHA) in the past 4 months between congestive heart failure (CHF) patients involved in a structured heart failure program (HFP) compared with waitlisted controls.

Methods:

This study, employing an ex-post-facto comparative cross-sectional design, involved 80 patients with CHF (40 in the HFP and 40 controls). Those in the HFP had been enrolled for at least 4 months. Controls were waiting to be enrolled in the program. Participants completed a questionnaire assessing demographic, social/cultural, psychological, and CHF-related physical health characteristics, along with the primary dependent variables, QOL and FHA. Bivariate and multivariate analyses assessed differences between those in the HFP and controls.

Results:

Congestive heart failure patients in the HFP were significantly less likely than the control group to score below the median on heart failure-specific QOL, controlling for other variables (OR=0.83, 95% CI: 0.82-0.95, p=0.007). Those in the HFP were also significantly less likely than controls to be hospitalized within the past 4 months (OR=0.78, 95% CI: 0.69-0.88, p<0.001). Multivariate analyses indicated that CHF patients in the HFP were 95% less likely than controls to be admitted to the hospital during that period, independent of other risk factors for hospital admission.

Conclusion:

Involvement by patients with CHF in a structured HFP at King Abdulaziz University in Jeddah, Kingdom of Saudi Arabia, is associated with significantly higher quality of life and lower likelihood of being hospitalized compared to CHF patients not involved.
