Depression in Patients With Heart Failure: Prevalence, Pathophysiological Mechanisms, and Treatment

Comparing network structures of depressive and anxiety symptoms between demographically-matched heart disease and heart disease free samples using propensity score matching: Findings from the Chinese Longitudinal Healthy Longevity Survey (CLHLS)

BACKGROUND

Older adults with heart disease often experience higher rates of comorbid anxiety and depression. This study examined depression and anxiety network structures among older adults with heart disease and their heart disease free peers.

METHODS

Network analyses of secondary cross-sectional data from the 2017 to 2018 wave of CLHLS were used to construct groups of older adults with and without heart disease using propensity score matching. Depression and anxiety symptoms were assessed using Center for Epidemiological Studies Depression Scale and Generalized Anxiety Disorder Scale, respectively. Central symptoms and bridge symptoms were identified using expected influence.

RESULTS

1689 older adults with heart disease and matched control sample of 1689 older adults without heart disease were included. The prevalence and severity of depression and anxiety were significantly higher in older adults with heart disease compared to the control group. There was no significant difference in overall structures of depression and anxiety network models between two the groups. Key central symptoms and bridge symptoms within these groups were highly similar; GAD 2 "Uncontrollable worrying" and GAD 4 "Trouble relaxing" were identified as the most central symptoms, while GAD 1 "Nervousness" and CESD 1 "Feeling bothered" were identified as key bridge symptoms across both network models.

CONCLUSION

Depression and anxiety are more prevalent in older adults with heart disease than demographically-matched heart disease free controls. However, network structures of these symptoms do not differ between two groups. Accordingly, depression and anxiety psychosocial interventions developed for older adults without heart disease may also benefit older adults with heart disease.

Effects of an interactive coaching intervention on quality of life and psychological factors for colorectal cancer survivors: A single group pre and posttest design

OBJECTIVE

To develop and evaluate the effects of an interactive coaching intervention, using a self-management mobile application, on quality of life and physical and psychological factors for colorectal cancer survivors.

METHODS

We developed a self-management mobile application providing social support services for post-treatment CRC survivors and evaluated its effects through baseline and post-intervention surveys. Using the biopsychosocial holistic model as the theoretical framework, automated interactive coaching technology was applied for six weeks to provide supportive services tailored for each user. To evaluate the effects of the application, self-efficacy, health practice index, depression, fear of cancer recurrence, and quality of life measures were administered to participants. A total of 34 men and 5 women were included in the analysis.

RESULTS

Participants' mean age were 54.10 years and 78% of them had been diagnosed within the last five years. There were significant increases in self-efficacy (z = 2.09, p = .04), health practice index (t = 2.35, p = .02), and quality of life (t = 2.03, p = .05). More specifically, the emotional functional score increased (z = 2.23, p = .03) while both of the total symptom score (t = 2.10, p = .04) and the fatigue symptom score (z = 2.54, p = .01) decreased after six weeks of using the mobile application.

CONCLUSIONS

Interventions supporting colorectal cancer survivors' self-management are critical for addressing the challenges they face after treatment and improving their quality of life. Providing social support through mobile applications could be a good strategy in terms of usability and effectiveness.

Heart failure and depression: A perspective from bibliometric analysis

Background

Depression commonly occurs in heart failure patients, and negatively influences quality of life and disease prognosis. This study explored heart failure and depression-related research from a bibliometric perspective.

Methods

Relevant publications were searched on June 24, 2022. The Bibliometrix package in R was used to conduct quantitative analyses including the trends in publications, and related countries, articles, authors and keywords. VOSviewer software was used to conduct the visualization map on co-word, co-author, and institution co-authorship analyses. CiteSpace software was used to illustrate the top keywords with citation burst.

Results

A total of 8,221 publications in the heart failure and depression-related research field were published between 1983 and 2022. In this field, the United States had the most publications (N = 3,013; 36.65%) and highest total citation (N = 149, 376), followed by China, Germany, Italy and Japan. Author Moser and Duke University were the most productive author and institution, respectively. Circulation is the most influential journal. Apart from "heart failure" and "depression," "quality of life," "mortality" and "myocardial infarction" were the most frequently used keywords in this research area; whereas more recently, "self care" and "anxiety" have been used more frequently.

Conclusion

This bibliometric analysis showed a rapid growth of research related to heart failure and depression from 1989 to 2021, which was mostly led by North America and Europe. Future directions in this research area include issues concerning self-care and anxiety about heart failure. As most of the existing literature were published in English, publications in other languages should be examined in the future.

Obesity and Uncontrolled Diabetes Predict Depression in HF Patients

BACKGROUND AND AIM

Heart failure (HF) is a clinical syndrome associated with poor quality of life and prognosis, and premature mortality. The aim of this study was to assess the prevalence of depression and its risk factors in HF patients.

METHODS

The study included 151 HF patients (mean age of 66.6 ± 11 years, 52.3% female). Based on ejection fraction (EF), the study cohort was divided into the following two groups: group-I: HFpEF patients (EF ≥ 50%, n = 47) and group-II: HFrEF patients (EF < 40%, n = 104). For the enrolled patients, demographic, clinic and echocardiographic indices, and depression scale results were collected.

RESULTS

The patients with HF and depression were older, mostly females, more obese, and had a higher glycemic level and higher NYHA functional class compared with the patients without depression (p < 0.05 for all). The left ventricle (LV) and left atrial (LA) dimensions were larger, and EF was lower, in patients with depression compared to those without depression (p < 0.05 for all), while the right ventricle (RV) measurements did not differ (p > 0.05). The same parameters remained significantly different when the patients were divided into HFpEF and HFrEF. The depression scale correlated with glycemic level (r = 0.51, p = 0.01), obesity (rpb = 0.53, p = 0.001), age (r = 0.47, p = 0.02), and severity of NYHA class (rpb = 0.54, p = 0.001). On a multivariate model, BMI ≥ 30 kg/m², OR 1.890 (1.199 to 3.551; 0.02) glycemic level ≥ 8.5 mmol/L, OR 2.802 (1.709 to 5.077; p = 0.01), and NYHA class > 2, OR 2.103 (1.389 to 4.700; p = 0.01), proved to be the most powerful independent predictors of depression, in the group as a whole. Obesity and uncontrolled diabetes predicted depression, irrespective of EF.

CONCLUSIONS

In this modest cohort of HF patients, obesity and uncontrolled diabetes were independent predictors of depression, irrespective of LV systolic function. This emphasizes the important role of medical education for better control of such risk factors.

Discrepancies between proxy estimates and patient reported, health related, quality of life: minding the gap between patient and clinician perceptions in heart failure

PURPOSE

Health related quality of life (HRQoL) is rarely routinely measured in the clinical setting. In the absence of patient reported data, clinicians rely on proxy and informal estimates to support clinical decisions. This study compares clinician estimates (proxy) with patient reported HRQoL in patients with advanced heart failure and examines factors influencing discrepancies.

METHODS

Seventy-five patients with heart failure, (22 females, 53 males) completed the EQ-5D-5L questionnaire. Thirty-nine clinicians (11 medical, 23 nursing, 5 allied health) completed the proxy version (V1) producing 194 dyads. Correlation was assessed using Spearman's rank tests, systematic bias was examined with Bland-Altman analyses. Inter-rater agreement at the domain level, was investigated using linear weighted Kappa statistics while factors influencing the IRG were explored using independent student t-tests, analysis of variance and regression.

RESULTS

There was a moderate positive correlation between clinician HRQoL estimates and patient reported utility (r = 0.38; p < .0005). Mean clinician estimates were higher than patient reported utility (0.60 vs 0.54; p = 0.008), with significant underestimation of reported problems apparent in three of the five EQ-5D-5L domains. Patient sex (female), depressed mood and frailty were all associated with an increased inter-rater gap.

CONCLUSION

Clinicians in this sample overestimated HRQoL. Factors affecting the inter-rater gap, including sex and depression, support formal HRQoL screening to enhance clinical conversations and decision making. The discrepancy also supports regulatory restriction on the use of expert opinion in the development of QALYs in health economic analysis.

Exercise Intolerance in Patients With Heart Failure: JACC State-of-the-Art Review

Exercise intolerance is the cardinal symptom of heart failure (HF) and is of crucial relevance, because it is associated with a poor quality of life and increased mortality. While impaired cardiac reserve is considered to be central in HF, reduced exercise and functional capacity are the result of key patient characteristics and multisystem dysfunction, including aging, impaired pulmonary reserve, as well as peripheral and respiratory skeletal muscle dysfunction. We herein review the different modalities to quantify exercise intolerance, the pathophysiology of HF, and comorbid conditions as they lead to reductions in exercise and functional capacity, highlighting the fact that distinct causes may coexist and variably contribute to exercise intolerance in patients with HF.

Discharge Education Intervention to Reduce Anxiety and Depression in Cardiac Surgery Patients: A Randomized Controlled Study

PURPOSE

This study aimed to determine possible effects of a discharge education intervention on anxiety and depression among cardiac surgery patients in a private hospital in the city of Ordu, Turkey.

DESIGN

A randomized controlled trial.

METHODS

Thirty-three patients were placed in standard care group and 33 into standard care plus discharge education group. Patients in the discharge education group were provided an individual training from the first day of the hospital admission until the day of the discharge. The standard care group received usual discharge instructions.

FINDINGS

The Hospital Anxiety and Depression Scale-anxiety subscale scores were not significantly different between patients in the discharge and standard care groups (group: F = 1.58; P > .05). There was a significant difference for depression, indicating that the discharge education group had significantly lower depression than the standard care group (group: F = 19.23; P < .01).

CONCLUSIONS

Our findings supported that the discharge education intervention reduced depression in cardiac surgery patients.

The Three Rs for Preventing Heart Failure Readmission: Review, Reassess, and Reeducate

Despite improvements in heart failure therapies, hospitalization readmission rates remain high. Nationally, increasing attention has been directed toward reducing readmission rates and thus identifying patients with the highest risk for readmission. This article summarizes the evidence related to decreasing readmission for patients with heart failure within 30 days after discharge, focusing on the acute setting. Each patient requires an individualized plan for successful transition from hospital to home and preventing readmission. Nurses must review the patient's current plan of care and adherence to it and look for clues to failure of the plan that could lead to readmission to the hospital. In addition, nurses must reassess the current plan with the patient and family to ensure that the plan continues to meet the patient's needs. Finally, nurses must continually reeducate patients about their plan of care, their plan for self-management, and strategies to prevent hospital readmission for heart failure.

Similar effects of low to moderate-intensity exercise program vs moderate-intensity continuous exercise program on depressive disorder in heart failure patients: A 12-week randomized controlled trial

BACKGROUND

Heart failure related depression is recently increased worldwide. Heart failure (HF) disease is identified as a critical cause of increasing morbidity, hospital readmission, and mortality. The most important purpose of treatment of HF disease is to relief disease problems, improve functional performance, and achieve better quality of life.

OBJECTIVES

This study was proposed to evaluate the effects of low to moderate-intensity exercise program vs moderate-intensity continuous exercise program on the level of depressive disorder in heart failure patients.

STUDY DESIGN

12-week randomized controlled trial.

METHODS

Sixty nine HF patients with mild to moderate level of depression and ejection fraction <40% were examined before and after 12-week intervention. Their age was ranged from 40 to 60 years. Patients were randomly classified into 3 groups. Group I (n = 23) received low to moderate intensity exercise program (LMIEP), group II (n = 23) received moderate-intensity exercise program (MICEP), and group III (n = 23) did not receive any exercise program (Non-exercised group). All patients were instructed to conduct home-based exercise with their pharmacological therapy. The level of depression was evaluated before and after 12 weeks of the intervention program.

RESULTS

The 3 study groups were associated with significant decrease of depression level (P < .05). Significant differences were exhibited between the 3 groups in favor to both exercise programs (P < .05) with non-significant differences between the 2 exercise programs (P > .05).

CONCLUSIONS

Both exercise programs had positive effects in reducing the severity of depression in HF patients. Low to moderate and moderate-intensity exercise programs should be proposed for depression illness specially patients with heart failure.

Depression in heart failure

Heart failure is one of the most prevalent long-term physical health conditions. It is suggested that up to 26 million people are living with it worldwide including approximately 920 000 people in the UK. Evidence has consistently demonstrated the links between cardiac health and mental health; therefore, this article will explain depression and its presentation in heart failure, as these two conditions have been strongly and consistently linked. The prevalence of depression in heart failure will be reviewed from epidemiological studies and an overview of the impact of comorbid depression in heart failure will be provided, with a particular focus on mortality, morbidity and quality of life outcomes. The relationship between depression and heart failure will be discussed by examining pathophysiological and behavioural mechanisms, as well as evidence regarding the appropriate identification and subsequent management of heart failure depression will be reviewed.

Examining the impacts of 12 weeks of low to moderate-intensity aerobic exercise on depression status in patients with systolic congestive heart failure - A randomized controlled study

OBJECTIVES

Psychiatric depression disorder is common in patients with systolic congestive heart failure (HF), and both conditions share underlying pathophysiological mechanisms. The incidence rate of depression disorder has clearly increased with the increase in HF manifestations in recent decades. Depression disorder is considered an independent predisposing factor for hospitalization, disturbed functional performance, and high rates of morbidity and mortality in HF patients. This randomized controlled study was designed to examine the impacts of low- to moderate-intensity aerobic exercise training on depression status in patients with systolic congestive HF.

METHODS

A total of 46 systolic congestive HF patients with depression (40-60 years of age) were randomized to receive twelve weeks of mild- to moderate-intensity aerobic exercise plus standard medical treatment (exercise group) or standard medical treatment without any exercise intervention (control group). Depression status was examined using the validated Patient Health Questionnaire-9 (PHQ9) pre- and post-intervention at the end of the study program.

RESULTS

No significant differences were observed between the exercise and control groups in demographic data or clinical characteristics (p>0.05). Both study groups showed a significant reduction in depression status at the end of the 12-week intervention (p<0.05). The comparison between the mean values of the depression scores showed significant differences between the two groups after 6 and 12 weeks of the intervention, indicating a greater reduction in depression scores in the exercise group than in the control group (p<0.05).

CONCLUSIONS

Twelve weeks of a low- to moderate-intensity aerobic exercise program was safe and effective for reducing depression severity in patients with systolic congestive HF. Low- to moderate-intensity aerobic training should be recommended for cardiac patients, particularly those with HF-related depression.

A Ventricular Assist Device Recipient and Suicidality: Multidisciplinary Collaboration With a Psychiatrically Distressed Patient

BACKGROUND

Ventricular assist device (VAD) recipients are at high risk of depression and anxiety, and poor psychosocial functioning is associated with worse medical outcomes.

PURPOSE

We present a case of a 31-year-old depressed patient who demonstrated passive suicidal behavior through multiple episodes of noncompliance, including temporarily discontinuing warfarin (Coumadin) several months after VAD implantation. The patient's psychosocial and medical histories and outcomes are presented.

CONCLUSIONS

This case underscores the importance of pre-VAD as well and ongoing psychosocial evaluation and management for this unique patient population.

CLINICAL IMPLICATIONS

Medical teams who are treating patients with cardiovascular disease who are under consideration for VAD or heart transplantation need to be aware of the multitude of ways in which patients can express depressed and suicidal mood and work with a multidisciplinary team to treat such symptoms to optimize patients' success with VAD/heart transplantation.

Depressive Symptoms and Physical Frailty in Older Adults With Chronic Heart Failure: A Cross-Sectional Study

Depressive symptoms and physical frailty have been reported to be predictive of adverse outcomes in individuals with heart failure (HF). Depressive symptoms could be a predisposing factor of physical frailty in older adults. Despite the high prevalence of HF, few studies on the relationship between these two factors have been performed in older adults with HF. To identify the relationship between depressive symptoms and physical frailty in HF, 190 older adults with HF were recruited from an outpatient clinic at a tertiary hospital in South Korea. The prevalence of depressive symptoms and physical frailty in older adults with HF was 30% (n = 57) and 61.6% (n = 117), respectively. Multivariate logistic regression revealed that depressive symptoms most strongly increased the risk of physical frailty after adjusting for confounding factors. Early detection of depressive symptoms might be useful to identify the status of physical frailty at the illness trajectories of HF in older adults and for judicious allocation of disease management strategies.

Factors associated with general practitioners' awareness of depression in primary care patients with heart failure: baseline-results from the observational RECODE-HF study

Background

Depression is more prevalent in patients with heart failure (HF) than in those without, but its detection is complicated by the symptom overlap between the two diseases. General practitioners (GPs) are the first point of contact for patients with HF. Therefore, this study aims to investigate GPs’ awareness of depression in their HF patients and factors associated with this awareness.

Methods

In this cross-sectional, observational study 3224 primary care patients with HF were screened for depressive symptomatology using an algorithm based on the Hospital Anxiety and Depression Scale, the 9-item subscale on Depression of the Patient Health Questionnaire, and selected items from the PROMIS Depression and Anxiety scales. The 272 GPs of all patients involved in the study were interviewed by telephone regarding their patients’ somatic and psychological comorbidities. The awareness rates of depressive symptomatology by the patients’ GPs are analyzed using descriptive statistics. Logistic regression analyses are applied to investigate the patient- and GP-based factors associated with the GPs’ awareness of depressive symptomatology.

Results

GPs were aware of their patients’ depressive symptomatology in 35% of all cases. Factors associated with the awareness of depressive symptomatology were: higher patient education levels, a history of depression known to the GP, GP-consultations due to emotional distress within the last 6 months, a higher frequency of GP-contacts within the last 6 months, a higher New York Heart Association (NYHA) classification and more severe depressive symptomatology. The GPs’ characteristics, including further education in psychology/psychiatry, were not associated with GP awareness.

Conclusions

Many aspects, including the definition of awareness and the practical issues in primary care, may contribute to the unexpectedly low awareness rates of depressive symptomatology in HF patients in primary care. Awareness rates might increase, if GPs encouraged their patients to talk about emotional distress, held detailed medical interviews including a patient’s history of depression and payed special attention to HF patients with low education levels. However, it remains to be investigated whether GPs’ judgement of depressive symptomatology is a better or worse indicator for the future prognosis and quality of life of HF patients than psychiatry based diagnostic criteria.

Diagnosis of Dilated Cardiomyopathy: Patient Reaction and Adaptation-Case Study and Review of the Literature

Objective. Heart failure remains a major cause of morbidity and mortality. Given that heart failure generally has a chronic course, it is important to appreciate the impact it can have on the quality of life of patients and also their partners or family carers. Method. Questionnaires were given to a patient newly diagnosed with dilated cardiomyopathy, during his hospital admission, as well as after discharge. The responses are summarised and explored in the discussion section, where we used review of the literature to discuss the implications of a new diagnosis of heart failure. Results. The patient's responses to the questionnaires suggest certain anxieties that are part of his adaptation to the diagnosis of heart failure. Conclusion. Depression is a common comorbid condition in patients with heart failure. Various tools can be used to screen for depression in patients with heart failure. Both pharmacological and nonpharmacological options are available. Rapid evaluation of ongoing problems and active participation by a psychiatrist can ensure that the patient receives the best possible clinical care.

Biopsychosocial predictors of coping strategies of patients postmyocardial infarction

Data from the Patients and Families Psychological Response to the Home Automated External Defibrillator Trial were used to examine the relationship between biopsychosocial variables and patients' coping strategies postmyocardial infarction. This study is the secondary data analysis of longitudinal observational study. A total of 460 patient-spouse pairs were recruited in January 2003 to October 2005. Hierarchical linear regression analysis examined biological/demographic, psychological and social variables regarding patients' coping scores using the Family Crisis Oriented Personal Evaluation Scale. Lower social support and social support satisfaction predicted lower total coping scores. Being younger, male gender and time since the myocardial infarction predicted lower positive coping strategy use. Higher anxiety and lower social support were related to fewer positive coping methods. Lower educational levels were related to increased use of negative coping strategies. Reduced social support predicted lower total coping scores and positive coping strategy use and greater passive coping style use. Social support from a broad network assisted with better coping; those living alone may need additional support. Social support and coping strategies should be taken into consideration for patients who have experienced a cardiac event.

The influence of depression and anxiety symptoms on health-related quality of life in patients with atrial fibrillation and atrial flutter

BACKGROUND

The health-related quality of life (HRQoL) of patients with atrial fibrillation (AF) and atrial flutter (AFL) is an important issue in cardiovascular health management. Determinants of poor HRQoL of AF/AFL patients require further elucidation.

OBJECTIVES

The purpose of this study was to evaluate the influencing factors related to the HRQoL of AF/AFL patients.

METHODS

In 150 consecutively recruited patients in a multicenter, cross-sectional study from April 2010 to February 2011, depression and anxiety were measured with the Beck Depression Inventory II and the State Trait Anxiety Inventory, respectively, whereas HRQoL was assessed with the generic Medical Outcomes Survey 36-Item Short-Form Survey version 2 and the Symptom Checklist. Linear regression modeling was performed to determine predictors of HRQoL among variables, including the patients' age, gender, race, marital status, type of AF/AFL, frequency of AF/AFL symptoms, time since diagnosis, and anxiety and depression symptoms.

RESULTS

Female patients with AF/AFL reported poorer physical HRQoL than male patients did (P < .001, R² = 0.391). Symptoms of depression and anxiety were found to be associated with poorer HRQoL (P < .001, R² = 0.482). Anxiety was the strongest predictor of the mental component of the Medical Outcomes Survey 36-Item Short-Form Survey version 2 and the Symptom Checklist. Younger patients had worse AF/AFL-related symptoms and severity than older patients did (P < .001, R² = 0.302). Increased frequency of symptomatic episodes was associated with worse AF/AFL-related symptoms and severity.

CONCLUSION

In conclusion, depression and anxiety symptoms and female gender emerged as clear indicators of poor HRQoL in AF/AFL patients. These risk factors should be used to identify patients who may require additional evaluation and treatment efforts to manage their cardiac conditions or HRQoL. Interventions to improve HRQoL in these individuals require further investigation.

A health education booklet and telephone follow-ups can improve medication adherence, health-related quality of life, and psychological status of patients with heart failure

BACKGROUND

Heart failure is an increasing public health problem globally. Interventions are imperative in managing the disease.

OBJECTIVE

To examine the effectiveness of a health education booklet and telephone follow-ups on patients' medication adherence, health-related quality of life, and psychological status.

METHODS

One hundred and sixty heart failure patients were assigned to either the experimental group (health education booklet and telephone follow-ups) or the control group (usual care). An independent t-test and the generalized estimating equation (GEE) model were used to compare the differences in the study outcomes. The statistical tests were two-sided and a p value below 0.05 was considered statistically significant.

RESULTS

The patients in the experimental group showed greater improvement throughout the study period compared with those in the control group regarding all the study outcomes.

CONCLUSIONS

The study provided clues for healthcare professionals to develop interventions while undertaking clinical work with limited resources in China.

Pathophysiological Relationships Between Heart Failure and Depression and Anxiety

Depression and anxiety are common comorbid conditions in patients with heart failure. Patients with heart failure and depression have increased mortality. The association of anxiety with increased mortality in patients with heart failure is not established. The purpose of this article is to illustrate the similarities of the underlying pathophysiology of heart failure, depression, and anxiety by using the Biopsychosocial Holistic Model of Cardiovascular Health. Depression and anxiety affect biological processes of cardiovascular function in patients with heart failure by altering neurohormonal function via activation of the hypothalamic-pituitary-adrenal axis, autonomic dysregulation, and activation of cytokine cascades and platelets. Patients with heart failure and depression or anxiety may exhibit a continued cycle of heart failure progression, increased depression, and increased anxiety. Understanding the underlying pathophysiological relationships in patients with heart failure who experience comorbid depression and/or anxiety is critical in order to implement appropriate treatments, educate patients and caregivers, and educate other health professionals.

Incidence and risk of mood disorders in patients with breast cancers in Taiwan: a nationwide population-based study

OBJECTIVE

The objective of this study is to assess the incidence and risk of mood disorders, including major depression, anxiety, and bipolar disorders, in Taiwanese patients after the diagnosis of breast cancer compared with a matched cohort.

METHODS

From January 2000 to December 2005, 26,629 newly diagnosed breast cancer patients were enrolled by the Taiwan National Health Insurance program database. The control cohort was selected randomly from 1,000,000 National Health Insurance beneficiaries from a population of 21,400,826 enrolled throughout Taiwan. Each patient was matched with one subject without breast cancer by age, sex, and presence of comorbidities with the same diagnosis index date. The diagnosis of mood disorders was defined by compatible International Classification of Diseases, 9th revision, clinical modification codes plus the prescription of antidepressants for at least 30 days.

RESULTS

The overall incidence rate ratio of mood disorders was 1.33 (95% CI 1.28-1.39, p < 0.001) in the breast cancer cohort compared with the matched cohort. The incidence rate ratios for specific mood disorders were 2.06 for bipolar disorder (95% CI 1.37-3.15 p = 0.0003), 1.94 for major depressive disorder (95% CI 1.76-2.13 p < 0.001), and 1.22 for anxiety (95% CI 1.16-1.27 p < 0.001). Independent risk factors for developing mood disorders included breast cancer, as well as age, hypertension, chronic obstructive pulmonary disease, autoimmune disease, ischemic heart disease, and cerebrovascular disease.

CONCLUSIONS

Breast cancer is a prominent risk factor for mood disorders, including major depressive disorder, anxiety, and bipolar disorder. The impact is most potent in the first year after diagnosis. Psychological support is a critical issue in these patients.

Predictors of Cognitive/Affective and Somatic Depression in Heart Failure Patients

The effects of depression on patients with heart failure (HF) are substantial, yet the predictors remain unclear. The predictors of cognitive/affective and somatic depression in stable HF patients were studied. Using a cross-sectional design, 150 HF outpatients were recruited at two mid-Western HF clinics. Predictors included dyspnea with activities of daily living, family and friend social support, and loneliness; age and gender were control variables. All constructs were measured using standardized instruments. Structural equation modeling (SEM) showed that cognitive/affective depression was predicted by greater dyspnea and loneliness, whereas somatic depression was predicted by more dyspnea and friend support. Also, greater dyspnea was related to more loneliness and less friend support; less friend support was related to loneliness. Women reported more dyspnea and loneliness. Since cognitive/affective and somatic depression have different predictors, further study is warranted to identify HF patients at risk for depression and to establish interventions targeted at improving depression.

Commonalities and differences in correlates of depressive symptoms in men and women with heart failure

OBJECTIVE

(i) To compare the prevalence and severity of depressive symptoms between men and women enrolled in a large heart failure (HF) registry. (ii) To determine gender differences in predictors of depressive symptoms from demographic, behavioral, clinical, and psychosocial factors in HF patients.

METHODS

In 622 HF patients (70% male, 61 ± 13 years, 59% NYHA class III/IV), depressive symptoms were assessed by the Patient Health Questionnaire (PHQ-9). Potential correlates were age, ethnicity, education, marital and financial status, smoking, exercise, body mass index (BMI), HF etiology, NYHA class, comorbidities, functional capacity, anxiety, and perceived control. To identify gender-specific correlates of depressive symptoms, separate logistic regression models were built by gender.

RESULTS

Correlates of depressive symptoms in men were financial status (p = 0.027), NYHA (p = 0.001); functional capacity (p < 0.001); health perception (p = 0.043); perceived control (p = 0.002) and anxiety (p < 0.001). Correlates of depressive symptoms in women were BMI (p = 0.003); perceived control (p = 0.013) and anxiety (p < 0.001).

CONCLUSIONS

In HF patients, lowering depressive symptoms may require gender-specific interventions focusing on weight management in women and improving perceived functional capacity in men. Both men and women with HF may benefit from anxiety reduction and increased control.

Evaluation and treatment of depression in patients with heart failure

PURPOSE

The purpose of this article is to provide an overview of relevant clinical issues including pathophysiology, clinical presentation, assessment/diagnosis, and treatment strategies regarding depression in the heart failure (HF) patient. This information was synthesized to create a clinical protocol to guide the practitioner in identifying, diagnosing, and treating depression in adult HF patients. This protocol was designed for use in the primary care or HF clinic setting.

DATA SOURCES

PubMed and CINAHL were utilized to search for articles pertaining to HF and depression.

CONCLUSIONS

The presence of depression in HF is associated with a worsening prognosis, increased risk of death, rehospitalization, and functional decline. The practitioner must identify predisposing factors for depression and evaluate symptoms. Self-rated screening instruments can assist the practitioner in identifying those with depression. Evidence is lacking regarding the treatment of depression in HF but selective serotonin reuptake inhibitors are likely the best option.

IMPLICATIONS FOR PRACTICE

Understanding depression as it occurs in patients with HF is critical. If depression is identified and properly managed it may lead to better patient outcomes.

Functional disability as an explanation of the associations between chronic physical conditions and 12-month major depressive episode

BACKGROUND

The link between physical conditions and mental health is poorly understood. Functional disability could explain the association of physical conditions with major depressive episode (MDE) as an intermediary factor.

METHODS

Data was analyzed from a subsample (N=8796) of the European Study of the Epidemiology of Mental Disorders (ESEMeD), a cross-sectional general population survey. MDE during the last 12 months was assessed using a revision of the Composite International Diagnostic Interview (CIDI 3.0). Lifetime chronic physical conditions were assessed by self-report. Functional disability was measured using a version of the World Health Organization Disability Assessment Schedule (WHODAS). The associations of physical conditions with MDE and explanation by functional disability were quantified using logistic regression.

RESULTS

All physical conditions were significantly associated with MDE. The increases in risk of MDE ranged from 30% for allergy to amply 100% for arthritis and heart disease. When adjusted for physical comorbidity, associations decreased and were no longer statistically significant for allergy and diabetes. Functional disability explained between 17 and 64% of these associations, most substantially for stomach or duodenum ulcer, arthritis and heart disease.

LIMITATIONS

Due to the cross-sectional nature of the study the temporal relationship of the variables could not be assessed and the amount of explanation cannot simply be interpreted as the amount of mediation.

CONCLUSIONS

Our findings suggest that the association of chronic physical conditions with MDE is partly explained by functional disability. Such explanation is more pronounced for pain causing conditions and heart disease. Health professionals should be particularly aware of the increased risk of depressive disorder when patients experience disability from these conditions.

Depression and perceptions about heart failure predict quality of life in patients with advanced heart failure

BACKGROUND

Mood is an independent predictor of mortality and quality of life (QoL) for people with heart failure. However, the underlying belief systems involved in mood are unknown.

OBJECTIVE

We sought to identify psychological and clinical variables predicting mood and QoL for people diagnosed with heart failure (HF).

METHODS

One hundred and forty-six HF patients were assessed with standardized measures, to determine their beliefs about HF, coping styles, mood, and QoL.

RESULTS

Patients with more negative beliefs about the consequences of HF and with less perceived control over symptoms showed maladaptive coping styles such as denial and behavioral disengagement, and more severe levels of depression and anxiety. Depression also independently predicted QoL outcomes.

CONCLUSIONS

Anxious and depressed patients have more negative beliefs about HF, leading to negative coping behaviors and poor QoL. Our evidence suggests that changing negative beliefs may improve the psychological well-being and QoL of patients, irrespective of disease severity.

The human-companion animal bond: how humans benefit

The human-animal bond is extremely important to most clients of small animal veterinary practices. Pet ownership, or just being in the presence of a companion animal, is associated with health benefits, including improvements in mental, social, and physiologic health status. This article provides the research data regarding the human health benefits of companion animals, animal-assisted therapy, animal-assisted activities, and assistance animals; reviews measures that can be taken to enable safe pet ownership for the immunocompromised, and discusses the veterinarian's role in supporting immune-compromised clients and clients who have assistance animals. Client education and enhanced veterinary care can reduce the risk from zoonotic diseases, even for the immunocompromised.
