Abstract
OBJECTIVE This study aimed to investigate the role of systemic inflammation in reduced cognitive functioning in patients with early-stage heart failure (HF) while determining associations with other cardiovascular risk factors. METHODS Patients with stage B HF (n = 270; mean [standard deviation] age = 66.1 [10.1] years) were examined cross-sectionally for relationships among cardiovascular disease (CVD) and psychological risk factors, C-reactive protein (CRP), and Montreal Cognitive Assessment (MoCA) scores. A subsample (n = 83) at high risk for stage C HF (B-type natriuretic peptide levels ≥65 pg/ml) were followed up for 12 months for relationships between CRP levels and cognitive function. RESULTS Baseline smoking (χ2 = 6.33), unmarried (χ2 = 12.0), hypertension (χ2 = 5.72), greater body mass index (d = 0.45), and physical fatigue (d = 0.25) were related to higher CRP levels (p values < .05). Cross-sectionally, CRP levels were negatively related to MoCA scores, beyond CVD (ΔR2 = 0.022, β = -0.170, p < .010) and psychological risk factors (ΔR2 = 0.016, β = 0.145, p < .027), and related to mild cognitive impairment criteria (odds ratio = 1.35, 95% confidence interval [CI] = 1.00-1.81, p = .046). Across 12 months, B-type natriuretic peptide high-risk patients with CRP levels ≥3 mg/L had lower MoCA scores (23.6; 95% CI = 22.4-24.8) than did patients with CRP levels <3 mg/L (25.4; 95% CI = 24.4-26.5; p = .024). CONCLUSIONS Patients with stage B HF and heightened CRP levels had greater cognitive impairment at baseline and follow-up, independent of CVD and potentially psychological risk factors. Low-grade systemic inflammation may be one mechanism involved in cognitive dysfunction at early stages of HF.

Abstract
Heart failure (HF) is a major and costly public health concern, and its prognosis is grim-with high hospitalization and mortality rates. HF affects millions of individuals across the world, and this condition is expected to become "the epidemic" of the twenty-first century (Jessup et al., 2016). It is well documented that individuals with HF experience disproportionately high rates of depression and that those who are depressed have worse clinical outcomes than their nondepressed counterparts. The purpose of this chapter is to introduce the reader to the study of depression in HF, and how psychoneuroimmunologic principles have been applied to further elucidate mechanisms (i.e., neurohormonal and cytokine activation) linking these comorbid disorders.

The relationship between pain, fatigue, depression and functional performance in stable heart failure. Heart Lung 2015; 44:107-12. [PMID: 25576085 PMCID: PMC4352387 DOI: 10.1016/j.hrtlng.2014.07.008] [Citation(s) in RCA: 59] [Impact Index Per Article: 6.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2014] [Revised: 06/26/2014] [Accepted: 07/02/2014] [Indexed: 11/29/2022]
Abstract
OBJECTIVE Evaluate the relationship between pain, fatigue, depression, demographic, clinical, and functional variables in stable heart failure (HF). BACKGROUND Pain, fatigue and depression are common in HF. Little is known about the relationship between pain, fatigue and depression and functional measures in this population. METHODS Secondary data analysis of a cross sectional study of 173 stable HF patients. Associations between clinical and demographic factors, pain (SF-36), depression (CES-D), and fatigue (MAF) to functional performance and capacity (SF-36 role limitations due to physical functioning and 6-Minute Walk Test) were evaluated using hierarchical multiple regressions. RESULTS The sample was 65% male with a mean age of 60. Fifty-seven percent (n = 100) had pain, 54% (n = 94) had fatigue, and 46% (n = 79) had depression. Pain, depression and fatigue were negatively associated with functional performance but not functional capacity when controlling for demographic and clinical covariates. CONCLUSIONS Pain, fatigue and depression were associated with decreased functional performance in stable HF. Symptom management interventions are needed in HF.

The contribution of illness perception to psychological distress in heart failure patients. BMC Psychol 2014; 2:50. [PMID: 25520809 PMCID: PMC4266484 DOI: 10.1186/s40359-014-0050-3] [Citation(s) in RCA: 38] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2014] [Accepted: 09/11/2014] [Indexed: 10/26/2022] Open
Abstract
BACKGROUND The influences on the psychological well-being of heart failure (HF) patients have received limited attention. Illness perceptions are a specific set of cognitive representations that have been shown to predict health-related outcomes in other patient groups. This study sought to explore the role of illness perceptions in the psychological well-being of HF patients by creating a profile of illness perceptions in HF and examining their relations with anxiety and depression. METHODS Participants were 95 consecutive outpatients. Indices of psychological well-being were depression and anxiety, measured using the Hospital Anxiety and Depression Scale (HADS). Illness perceptions were measured using the Illness Perception Questionnaire - Revised (IPQ-R). Functional status was also determined using the New York Heart Association (NYHA) classification. RESULTS Illness perceptions were associated with indices of psychological well-being. Regression analyses showed that illness perceptions accounted for a significant proportion of the variance in both depression and anxiety. The contribution of illness perceptions was greater than that made by traditional covariates (socio-demographic variables and functional status). CONCLUSIONS Results highlight dynamic interrelations between perceptions of illness and mental health indices. They also suggest that in considering the role of illness perceptions in psychological well-being, the primary focus should be on the overall dynamic of an individual's illness experience rather than on specific illness dimensions. Findings highlight the potential role of illness perceptions in depression and anxiety in HF. This has implications for interventions to maximise psychological well-being in this patient group.

Abstract
BACKGROUND Inflammation may be a link between depressive symptoms and outcomes in patients with heart failure. It is not clear whether inflammatory markers are independently related to depressive symptoms in this population. AIM To determine which inflammatory biomarkers are independently associated with depressive symptoms in heart failure. METHODS AND RESULTS We analyzed data from 428 outpatients enrolled in a heart failure registry (32% female, 61 ± 12 years, 48% New York Heart Association Class III/IV). Depressive symptoms were measured with the Beck Depression Inventory-II. Serum C-reactive protein (CRP), cytokines (interleukin 1 receptor antagonist, 2, 4, 6, 8, 10), tumor necrosis alpha, and soluble receptors sTNFR1 and sTNFR2 were measured with enzyme immunoassay. Multiple regressions were used to determine which biomarkers were associated with depressive symptoms controlling for demographics, heart failure severity, and clinical variables. Twenty-seven percent (n = 119) had depressive symptoms. CRP was related to depressive symptoms after controlling for age and gender, but no inflammatory biomarkers were associated with depressive symptoms after controlling for all variables in the model. CONCLUSIONS There was no relationship between inflammatory biomarkers and depressive symptoms. Our findings, in combination with prior researchers', suggest there is not a robust relationship between depressive symptoms and individual biomarkers of inflammation in heart failure.

Diagnosis and treatment of depression in patients with congestive heart failure: a review of the literature. Prim Care Companion CNS Disord 2013; 15:13r01511. [PMID: 24392265 DOI: 10.4088/pcc.13r01511] [Citation(s) in RCA: 32] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2013] [Accepted: 04/12/2013] [Indexed: 01/02/2023] Open
Abstract
CONTEXT Major depressive disorder (MDD) can be challenging to diagnose in patients with congestive heart failure, who often suffer from fatigue, insomnia, weight changes, and other neurovegetative symptoms that overlap with those of depression. Pathophysiologic mechanisms (eg, inflammation, autonomic nervous system dysfunction, cardiac arrhythmias, and altered platelet function) connect depression and congestive heart failure. OBJECTIVE We sought to review the prevalence, diagnosis, neurobiology, and treatment of depression associated with congestive heart failure. DATA SOURCES A search of all English-language articles between January 2003 and January 2013 was conducted using the search terms congestive heart failure and depression. STUDY SELECTION We found 1,498 article abstracts and 19 articles (meta-analyses, systematic reviews, and original research articles) that were selected for inclusion, as they contained information about our focus on diagnosis, treatment, and pathophysiology of depression associated with congestive heart failure. The search was augmented with manual review of reference lists of articles from the initial search. Articles selected for review were determined by author consensus. DATA EXTRACTION The prevalence, diagnosis, neurobiology, and treatment of depression associated with congestive heart failure were reviewed. Particular attention was paid to the safety, efficacy, and tolerability of antidepressant medications commonly used to treat depression and how their side-effect profiles impact the pathophysiology of congestive heart failure. Drug-drug interactions between antidepressant medications and medications used to treat congestive heart failure were examined. RESULTS MDD is highly prevalent in patients with congestive heart failure. Moreover, the prevalence and severity of depression correlate with the degree of cardiac dysfunction and development of congestive heart failure. Depression increases the risk of congestive heart failure, particularly in those patients with coronary artery disease , and is associated with a poorer quality of life, increased use of health care resources, more frequent adverse clinical events and hospitalizations, and twice the risk of mortality. CONCLUSIONS At present, limited empirical data exist with regard to treatment of depression in the increasingly large population of patients with congestive heart failure. Evidence reveals that both psychotherapeutic treatment (eg, cognitive-behavioral therapy) and pharmacologic treatment (eg, use of the selective serotonin reuptake inhibitor sertraline) are safe and effective in reducing depression severity in patients with cardiovascular disease. Collaborative care programs featuring interventions that work to improve adherence to medical and psychiatric treatments improve both cardiovascular disease and depression outcomes. Depression rating scales such as the 9-item Patient Health Questionnaire should be used to monitor therapeutic efficacy.

Abstract
OBJECTIVES Researchers have proposed biological (inflammation) and psychological (depression) factors as potential mechanisms for poorer outcomes and readmissions in heart failure (HF) patients. However, studies investigating the link between inflammation and depressive symptoms in these patients are few. We examined the relationships between levels of the inflammatory markers C-reactive protein (CRP), interleukin (IL)-6, and soluble tumor necrosis factor receptor 2 (sTNR2) and depressive symptoms in HF outpatients. METHOD 55 patients (74.5% men; 60% Whites; mean age 71.6 ± 11.3 years) with New York Heart Association Class II, III, or IV HF (49%, 47%, and 4%, respectively) and mean ejection fraction (EF) 29.9 ± 7.1% completed the Patient Health Questionnaire (PHQ)-9 as a measure of depressive symptoms. We also obtained height, weight, and CRP, IL-6, and sTNFR2 levels. We used multivariate regressions to assess the predictive value of PHQ-9 scores on each inflammatory marker. RESULTS 22 (40%) participants reported depressive symptoms (PHQ-9 score ≥ 5). After controlling for age, gender, body mass index, HF etiology, EF, and statin use, we found significant relationships between levels of both sTNFR2 (β = .35, p = .01) and IL-6 (β = .30, p = .04), but not CRP (β = -.96, p = .52), and depression scores. CONCLUSION Our findings add to a growing body of evidence supporting the proposition that heightened inflammation explains the effect depression has on HF. Health care providers should screen for depression in HF patients, as they may be at higher risk of augmented inflammation and poor outcomes.

Does depression impact cognitive impairment in patients with heart failure? Cardiol Res Pract 2012; 2012:524325.

Abstract
Prevalence studies have noted the cooccurrence of cognitive decline and depression in persons with heart failure. Cognitive impairment is associated with significant mortality and deteriorated quality of life, likely due to impairments in memory and executive function, which impact a patient's ability to understand and comply with prescribed treatment plans. This is especially true in complex diseases such as heart failure. Evidence from literature supports the possibility of a pathophysiological relationship between cognitive impairment, depression, and heart failure. Yet, very few studies have sought to investigate this relationship. This paper reviews current literature on the association between depression and cognitive impairment in persons with heart failure and explores possible mechanisms explaining this complex triad.

A genetic predisposition to produce low levels of IL-10 is related to depressive symptoms: a pilot study of patients with end stage renal disease. PSYCHOSOMATICS 2012; 53:155-61.

Abstract
OBJECTIVE Heightened levels of inflammation may be associated with an increased risk of depression, particularly among those with inflammatory medical conditions. Although elevated rates of both systemic inflammation and depression have been documented among patients with end stage renal disease (ESRD), the link between these factors has received little empirical evaluation. The goal of this pilot study was to investigate the association between cytokine gene polymorphisms (that are known to influence pro- and anti-inflammatory cytokine production) and depressive symptoms among patients with ESRD. METHODS Ninety-three patients with ESRD completed the Beck Depression Inventory-II and the disease-related symptom subscale of the Kidney Disease Quality of Life short form. Patients were genotyped for eight single nucleotide polymorphisms in genes coding for pro-inflammatory (TNF-α, IL-6, IFN-γ) and anti-inflammatory (IL-10, TGF-β1) cytokines. RESULTS Regression analyses indicated that patients with the A/A genotype for the IL-10 -1082 polymorphism (lower IL-10 producers) reported significantly greater depressive symptoms than G allele carriers (higher IL-10 producers; b = 0.22, P = 0.011), even after controlling for relevant covariates. CONCLUSION These findings provide some support for cytokine theories of depression in the medically ill, and specifically for the protective role of anti-inflammatory processes. Further research is needed to confirm these preliminary results and to explore the possibility of identifying subtypes of depressed patients based on inflammatory profiles, and those who may benefit from anti-inflammatory therapies.

Cognitive/affective and somatic/affective symptom dimensions of depression are associated with current and future inflammation in heart failure patients. J Affect Disord 2012; 136:567-76.

Abstract
BACKGROUND Little is known about whether cognitive/affective depressive symptoms or somatic/affective depressive symptoms are associated with inflammation in heart failure (HF), or that the relation is confounded with disease severity. AIM To examine the association between depressive symptom dimensions in HF patients with inflammatory markers cross-sectionally and prospectively, while adjusting for appropriate confounders. RESULTS Consecutive HF patients completed the Beck Depression Inventory at inclusion and at 12 month follow-up. Cytokines were assessed at both occasions. Cross-sectional--multivariate linear regression analysis (n=110) demonstrated that cognitive/affective depressive symptoms were independently associated with increased levels of sTNFR2 (β=0.20, p<0.05) and IL-1ra (β=0.28, p<0.01). Somatic/affective depressive symptoms were independently related to sTNFR2 (β=0.21, p<0.05). Prospective--(n=125) the level of cognitive/affective depressive symptoms at inclusion was prospectively associated with increased levels of sTNFR1 and sTNFR2 (β=0.21 and 0.25 resp. p<0.05), independent of covariates. Change in somatic/affective depressive symptoms over the 12 month period was associated with sTNFR2 (β=0.30, p=0.008). At symptom level, core depressive cognitions such as hopelessness and guilt drove the relation between the sTNF receptors and the cognitive/affective component, while having sleep problems was the most important associate of the somatic/affective dimension. CONCLUSIONS Baseline cognitive/affective depressive symptoms were prospectively associated with sTNFR1 and sTNFR2 in HF patients, while change in somatic/affective depressive symptoms was associated with sTNFR2, independent from clinical and demographic covariates. Further studies are warranted to replicate these findings and to examine the association between depression dimensions, inflammation and prognosis in HF.

Abstract
BACKGROUND Depressive symptoms in patients with heart failure (HF) are common and might be associated with inflammation. No studies have examined both the cross-sectional and prospective association between inflammation and depressive symptoms in patients with HF with adequate correction for disease severity. The aim of this study was to describe if the cytokines interleukin-6 (IL-6) and C-reactive protein (CRP) are associated with depressive symptoms in hospitalized HF patients. METHODS Data from 517 patients hospitalized for HF from the COACH study were analyzed on inflammation markers (IL-6 and CRP) and depressive symptoms (Center for Epidemiological Studies Depression-Scale). RESULTS Heart failure patients with depressive symptoms (n = 208, 40%) had significantly higher plasma values of IL-6 (median 12.8 pg/mL vs median 11.0 pg/mL, P = .018) and CRP (median 2.4 mg/mL vs median 2.1 mg/mL, P = .03) compared with the nondepressed patients. Structural equation modelling showed that the factor inflammation (including IL-6 and CRP) was associated with depressive symptoms (β = 0.18, P < .05) when left ventricular ejection fraction and plasma values brain natriuretic peptides were included in the model. A small negative (β = -0.18, P < .05) effect was found between inflammation at baseline and the change in depressive symptoms during the 18 months of follow-up. CONCLUSIONS Higher levels of inflammatory markers are independently associated with depressive symptoms in HF patients, even after correcting for disease severity. There is no clear relationship between inflammation at baseline and depressive symptoms during the 18 months of follow-up.

Abstract
The etiology, predictive value, and biobehavioral aspects of depression in heart failure (HF) are described in this article. Clinically elevated levels of depressive symptoms are present in approximately 1 out of 5 patients with HF. Depression is associated with poor quality of life and a greater than 2-fold risk of clinical HF progression and mortality. The biobehavioral mechanisms accounting for these adverse outcomes include biological processes (elevated neurohormones, autonomic nervous system dysregulation, and inflammation) and adverse health behaviors (physical inactivity, medication nonadherence, poor dietary control, and smoking). Depression often remains undetected because of its partial overlap with HF-related symptoms and lack of systematic screening. Behavioral and pharmacologic antidepressive interventions commonly result in statistically significant but clinically modest improvements in depression and quality of life in HF, but not consistently better clinical HF or cardiovascular disease outcomes. Documentation of the biobehavioral pathways by which depression affects HF progression will be important to identify potential targets for novel integrative behavioral and pharmacologic interventions.

Abstract
The purpose of this study was to analyse the major compound in the leaf essential oil of Cinnamomum osmophloeum Kaneh. and to examine its in vivo toxicity and cytokine-modulatory effects. The HS-GC/MS and quantitative HPLC analyses showed the concentrations of the major compounds, cinnamaldehyde, benzaldehyde and 3-phenylpropionaldehyde, in the leaf essential oil of Cinnamomum osmophloeum to be 16.88, 1.28 and 1.70 mg/mL, respectively. Acute and sub-acute toxicity tests identified no significant changes in body weight, liver and kidney function indices, and pathology for the mice treated with up to 1 mL/kg body weight of Cinnamomum osmophloeum leaf essential oil or up to 4 mg/kg body weight of cinnamaldehyde. A murine model was established using ovalbumin (OVA)-primed Balb/C mice treated with various concentrations of Cinnamomum osmophloeum leaf essential oil or cinnamaldehyde daily for 4 weeks. The results of tests with commercial ELISA kits indicated no significant cytokine-modulatory effects in mice treated with Cinnamomum osmophloeum leaf essential oil; however, the serum concentrations of IL-2, IL-4 and IL-10, but not IFN-γ, significantly increased in animals treated with 1 mg/kg body weight of cinnamaldehyde during the 4-week period. The possibility that the other constituents act as antagonists of cinnamaldehyde cannot be excluded.

Predictive value of depressive symptoms and B-type natriuretic peptide for new-onset heart failure and mortality. Am J Cardiol 2011; 107:723-9.

Abstract
Depression and natriuretic peptides predict heart failure (HF) progression, but the unique contributions of depression and biomarkers associated with HF outcomes are not known. The present study determined the additive predictive value of depression and aminoterminal pro-B-type natriuretic peptide (NT-proBNP) for new-onset HF in HF-free subjects and mortality in patients with HF. The participants in the Cardiovascular Health Study were assessed for depressive symptoms using the Center for Epidemiologic Studies Depression Scale and NT-proBNP using an electrochemiluminescence immunoassay. The validated cutoff values for depression (Center for Epidemiologic Studies Depression Scale ≥8) and NT-proBNP (≥190 pg/ml) were used. The risks of incident HF and mortality (cardiovascular disease-related and all-cause) were examined during a median follow-up of 11 years, adjusting for demographics, clinical factors, and health behaviors. In patients with HF (n = 208), depression was associated with an elevated risk of cardiovascular disease mortality (hazard ratios [HR] 2.07, 95% confidence interval [CI] 1.31 to 3.27) and all-cause mortality (HR 1.49, 95% CI 1.05 to 2.11), independent of the NT-proBNP level and covariates. The combined presence of depression and elevated NT-proBNP was associated with substantially elevated covariate-adjusted risks of cardiovascular disease mortality (HR 5.42, 95% CI 2.38 to 12.36) and all-cause mortality (HR 3.72, 95% CI 2.20 to 6.37). In the 4,114 HF-free subjects, new-onset HF was independently predicted by an elevated NT-proBNP level (HR 2.27, 95% CI 1.97 to 2.62) but not depression (HR 1.08, 95% CI 0.92 to 1.26) in covariate-adjusted analysis. In conclusion, depression and NT-proBNP displayed additive predictive value for mortality in patients with HF. These associations can be explained by complementary pathophysiologic mechanisms. The presence of both elevated depression and NT-proBNP levels might improve the identification of patients with HF with a high risk of mortality.

Abstract
In order to assess the relationships among mood, peripheral autonomic output and circulating immunoinflammatory mediators in older individuals with decompensated heart failure (CHF), 20 consecutive patients (78+/-7 years, 35% women) admitted to the coronary care unit with a clinical diagnosis of acute/decompensated CHF of coronary origin were examined. Mood was evaluated by the 21-item Hamilton Depression Scale (HAM-D). Four patients met the criteria for major depression. Heart rate variability (HRV) analysis and the levels of tumour necrosis factor (TNF)-alpha, interferon (IFN)-gamma, interleukin (IL)-2, IL-4, IL-6 and IL-10 were measured within 24-72 h of admission. A significant positive relationship between score in HAM-D and serum IL-6 levels was detected with a similar trend as far as IL-2 levels. Circulating IL-2 levels were strongly associated with the HRV L/H quotient, an index of increased sympathetic and/or decreased parasympathetic thoracic activity. A negative correlation between vagal activity (as assessed by HRV) and IL-4 occurred. Neither TNF-alpha nor IL-10 were detectable in this group of elderly patients. The results add to the concept that mood and autonomic unbalance are associated with increased systemic inflammation in old patients with decompensated CHF, a potential mechanism for mood-related worsened prognosis of heart failure at an advanced age.

Abstract
BACKGROUND Major depression occurs in 4.4% to 20% of the general population. Studies suggest that major depression is accompanied by immune dysregulation and activation of the inflammatory response system (IRS). Our objective was to quantitatively summarize the data on concentrations of specific cytokines in patients diagnosed with a major depressive episode and controls. METHODS We performed a meta-analysis of studies measuring cytokine concentration in patients with major depression, with a database search of the English literature (to August 2009) and a manual search of references. RESULTS Twenty-four studies involving unstimulated measurements of cytokines in patients meeting DSM criteria for major depression were included in the meta-analysis; 13 for tumor necrosis factor (TNF)-alpha, 9 for interleukin (IL)-1beta, 16 for IL-6, 5 for IL-4, 5 for IL-2, 4 for IL-8, 6 for IL-10, and 4 for interferon (IFN)-gamma. There were significantly higher concentrations of TNF-alpha (p < .00001), weighted mean difference (WMD) (95% confidence interval) 3.97 pg/mL (2.24 to 5.71), in depressed subjects compared with control subjects (438 depressed/350 nondepressed). Also, IL-6 concentrations were significantly higher (p < .00001) in depressed subjects compared with control subjects (492 depressed/400 nondepressed) with an overall WMD of 1.78 pg/mL (1.23 to 2.33). There were no significant differences among depressed and nondepressed subjects for the other cytokines studied. CONCLUSIONS This meta-analysis reports significantly higher concentrations of the proinflammatory cytokines TNF-alpha and IL-6 in depressed subjects compared with control subjects. While both positive and negative results have been reported in individual studies, this meta-analytic result strengthens evidence that depression is accompanied by activation of the IRS.

Circulating levels of soluble intercellular adhesion molecule-1 (sICAM-1) independently predict depressive symptom severity after 12 months in heart failure patients. Brain Behav Immun 2010; 24:366-9. [PMID: 19217936 DOI: 10.1016/j.bbi.2009.02.004] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/19/2008] [Revised: 01/21/2009] [Accepted: 02/04/2009] [Indexed: 11/25/2022] Open
Abstract
OBJECTIVE To determine whether inflammatory markers prospectively predict depressive symptom severity 12 months later in heart failure (HF) patients. METHODS In 30 HF patients we assessed depressive symptom severity by the Beck depression inventory (BDI) at baseline as well as 12 months later. We measured circulating levels of the soluble intercellular adhesion molecule (sICAM)-1, the cytokine interleukin (IL)-6 and the acute phase protein C-reactive protein (CRP) at baseline assessment. RESULTS sICAM-1 (r=.38, p=.045) but not CRP or IL-6 correlated with BDI scores 12 months later. Hierarchical linear regression analysis revealed that independent of baseline BDI assessment, cardiovascular risk factors, indicators of HF disease severity, and medication intake, sICAM-1 significantly predicted BDI scores 12 months later. sICAM-1 independently explained between 7% (beta=.26, p=.040) and 10% (beta=.35, p=.045) of the total variance in BDI scores 12 months later. CONCLUSION The findings from this exploratory analysis suggest that the adhesion molecule sICAM-1 is an independent predictor of depressive symptoms 12 months later in HF patients. Our prospective findings support the suggested role for inflammation in increasing future depressive symptom severity and extend this linkage for the first time to HF.

Association between type D personality, depression, and oxidative stress in patients with chronic heart failure. Psychosom Med 2009; 71:973-80. [PMID: 19834046 DOI: 10.1097/psy.0b013e3181bee6dc] [Citation(s) in RCA: 63] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 11/25/2022]
Abstract
OBJECTIVE To examine whether markers of oxidative stress differ as a function of Type D personality, depression, and chronic heart failure (CHF) etiology. Type D (distressed) personality and depression are related to poor cardiac prognosis. Because patients with CHF are characterized by increased oxidative stress, this may be a candidate mechanism responsible for the adverse prognosis in emotionally distressed patients with CHF. METHODS Serum levels of xanthine oxidase (XO), inducible heat shock protein (Hsp)70, and deoxyribonucleic acid damage marker 8-OHdG were measured in 122 patients, and effects of Type D, depression, and etiology were assessed. RESULTS CHF patients with Type D personality had lower levels of Hsp70 than non-Type D patients (6.48 ng/mL versus 7.85 ng/mL, p = .04, d = 0.26), and in case of an ischemic etiology, higher levels of XO (13.57 ng/mL versus 9.84 ng/mL, p = .01, d = 0.98). There were no significant univariate differences for depression. When adding depression as an additional independent variable in the Type D analysis, the effect of Type D personality remained significant (F = 5.460, p = .02) and was independent of depression (F = 0.942, p = .33). The ratio of XO to Hsp70 was significantly higher in Type D patients with CHF as compared with non-Type D patients (6.14 versus 2.83, p = .03, d = 0.39), independent of etiology class. CONCLUSION CHF patients with Type D personality are characterized by an increased oxidative stress burden, apparent in the decreased antioxidant levels and an increased oxidative stress ratio.

Relationship of depressive symptoms with hospitalization and death in Japanese patients with heart failure. J Card Fail 2009; 15:912-9. [PMID: 19944369 DOI: 10.1016/j.cardfail.2009.06.442] [Citation(s) in RCA: 33] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2009] [Revised: 06/28/2009] [Accepted: 06/30/2009] [Indexed: 11/20/2022]
Abstract
BACKGROUND Depressive symptoms are risk factors for poor outcomes and are positively associated with disease severity in patients with heart failure (HF). However, little is known about this association in the Japanese population. Therefore, we evaluated the prevalence of depressive symptoms and whether depressive symptoms predicted hospitalization for HF and death independent of disease severity and other factors in HF patients. METHODS AND RESULTS A 2-year prospective cohort study was conducted on 115 outpatients with HF (73.9% males; mean age 64.7 years) in Tokyo. Of these, 27 patients (23.5%) were classified as having depressive symptoms (Center for Epidemiologic Studies Depression Scale score >or=16). Patients with depressive symptoms had higher rates of 2-year cardiac death or HF hospitalization (34.0% vs. 10.3%; P < .01), HF hospitalization (27.4% vs. 9.2%; P = .01), and all-cause death (27.4% vs. 7.2%; P < .01). Multivariate Cox regression analyses indicated that depressive symptoms were predictors of cardiac death or HF hospitalization (hazard ratio [HR], 3.29; P = .02), HF hospitalization (HR, 3.36; P = .04), and all-cause death (HR, 5.52; P = .01), independent of age and brain natriuretic peptide. CONCLUSIONS Depressive symptoms were common and independent predictors of poor outcomes in Japanese patients with HF.

Abstract
AIMS To examine the impact of depressive symptoms on rehospitalisation for heart failure exacerbation in patients with preserved systolic function. BACKGROUND Depressive symptoms associated with higher risk of rehospitalisation have been primarily demonstrated in heart failure patients with systolic dysfunction (ejection fraction <40%) and the factors influencing rehospitalisation of patients with preserved systolic function (ejection fraction > or =40%) remain unclear. DESIGN A prospective, descriptive study design was used. METHODS The following baseline data were collected from 165 patients with preserved systolic function during an index hospitalisation for heart failure in South Korea: age, gender, body mass index, New York Heart Association functional class, the ratio of mitral velocity to early diastolic velocity of the mitral annulus, comorbidities, history of prior admission and depressive symptoms. Patients were followed monthly for six months after discharge to collect date on all rehospitalisation for heart failure exacerbation. Hierarchical Cox proportional hazards regression was used to identify independent predictors of rehospitalisation. Kaplan-Meier survival curves with log-rank test were used to determine differences in time to rehospitalisation according to severity of depressive symptoms. RESULTS Almost half of the patients (48%) had moderate to severe depressive symptoms. The ratio of mitral velocity to early diastolic velocity of the mitral annulus (hazard ratio = 1.06, 95% confidence interval = 1.02-1.10) and depressive symptoms (hazard ratio = 1.05, 95% confidence interval = 1.02-1.08) independently predicted rehospitalisation after controlling for other risk factors. Moderate and severe depressive symptoms were associated with both a higher rate and shorter time to rehospitalisation. CONCLUSIONS Moderate to severe depressive symptoms predict early rehospitalisation for heart failure exacerbations in patients with preserved systolic function. RELEVANCE TO CLINICAL PRACTICE Nurses should assess for depressive symptoms in patients with heart failure and refer those with depressive symptoms for treatment to improve outcomes.

A potential shift from adaptive immune activity to nonspecific inflammatory activation associated with higher depression symptoms in chronic heart failure patients. J Card Fail 2009; 15:607-15. [PMID: 19700138 DOI: 10.1016/j.cardfail.2009.01.011] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2008] [Revised: 01/21/2009] [Accepted: 01/26/2009] [Indexed: 11/18/2022]
Abstract
BACKGROUND Chronic heart failure (CHF) patients with elevated depression symptoms are at greater risk of morbidity and mortality. The mechanisms linking symptoms of depression with disease progression in CHF are unclear. However, research studies have found evidence of alterations in immune activity associated with depression symptoms that may influence heart function. The present study sought to determine the relationship between depression symptoms and chemotaxis of peripheral blood mononuclear cells (PBMCs) in CHF patients, both at rest and in response to moderate exercise. METHODS AND RESULTS Sixty-five patients diagnosed with CHF (mean age, 59.8 +/- 14.5 years) and 45 non-CHF control subjects (mean age, 52.1 +/- 11.6) completed the Beck Depression Inventory (BDI) before undergoing a moderate 20-minute bicycle exercise task. Chemotaxis of PBMCs was examined in vitro to a bacterial peptide f-met leu phe (fMLP) and a physiologic chemokine, stromal cell derived factor-1 (SDF-1) immediately before and after exercise. CHF patients had reduced chemotaxis to SDF-1 (P = .025) compared with non-CHF subjects. Higher BDI scores were associated with reduced baseline chemotaxis to SDF-1 in both CHF and non-CHF subjects (P = .027). In contrast, higher BDI scores were associated with increased chemotaxis to fMLP (P = .049) and SDF-1 (P = .018) in response to exercise in the CHF patients. CONCLUSION The present study suggests a shift in immune cell mobility in CHF patients with greater depression symptom severity, with reduced chemotaxis to a physiologically specific chemokine at rest but increased chemotaxis to both nonspecific and specific chemical attractants in response to physical activity. This could have implications for cardiac repair and remodeling in CHF patients and therefore may affect disease progression.

Usefulness of Type D personality and kidney dysfunction as predictors of interpatient variability in inflammatory activation in chronic heart failure. Am J Cardiol 2009; 103:399-404. [PMID: 19166697 DOI: 10.1016/j.amjcard.2008.09.096] [Citation(s) in RCA: 58] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/23/2008] [Revised: 09/23/2008] [Accepted: 09/23/2008] [Indexed: 11/19/2022]
Abstract
Tumor necrosis factor-alpha (TNF-alpha), soluble TNF-alpha receptors 1 and 2 (sTNFR1/2), and interleukin (IL)-6 are powerful predictors of mortality in chronic heart failure (CHF). Little is known, however, about the origins of proinflammatory cytokine production or the determinants of substantial interpatient variability in inflammatory activation. We prospectively examined kidney dysfunction and Type D personality (tendency to experience and inhibit emotional distress) as predictors of interpatient variability in these markers of inflammatory activation. At baseline, 125 patients with CHF were assessed for kidney dysfunction and Type D. Serum levels of proinflammatory cytokines (TNF-alpha, sTNFR1, sTNFR2, IL-6), the anti-inflammatory cytokines IL-10, and IL-1 receptor antagonist were measured at 1-year follow-up. Type D patients had higher levels of sTNFR1 (p = 0.009) and sTNFR2 (p = 0.001) and lower levels of IL-10 (p = 0.006) than patients without Type D and kidney dysfunction. Patients with kidney dysfunction also had elevated levels of sTNFR1 and sTNFR2 (p <0.0001), but their IL-10 level was not decreased. Type D personality and kidney dysfunction predicted increased sTNFR1/IL-10 and sTNFR2/IL-10 ratios (p < or =0.007); Type D also predicted an increased IL-6/IL-10 ratio (p = 0.013). Other predictors were spironolactone and older age. After adjusting for these variables, the odds for elevated ratios (highest 20%) were still increased in Type D patients (all odd ratios >3.00). In conclusion, Type D personality and kidney dysfunction independently predicted unfavorable cytokine profiles in patients with CHF and may enhance our understanding of interpatient variability in inflammatory activation in these patients.

Psychological predictors of prognosis in chronic heart failure. J Card Fail 2008; 14:341-50.

Abstract
BACKGROUND Chronic heart failure (CHF) is an increasingly prevalent condition with high mortality and morbidity rates. This review examines the role of depression, anxiety, and social support on prognosis in CHF. METHOD AND RESULTS Prospective studies that examined mortality as an outcome, and assessed depression, anxiety, or social support as associates were included. Methodological qualities were evaluated. In total, 25 studies were identified. Concerning depression, 6 of 15 studies of inpatients, 10 of 11 studies of outpatients, and 1 study of a mixed sample found associations between depression and prognosis, with greater associations rendered by depressive symptomatology in outpatients. Anxiety was not associated with prognosis in one inpatient study and one outpatient study. There was a univariable trend in one outpatient study for anxiety to be associated with prognosis. In two of six studies of inpatients and in two of four studies of outpatients, social support was associated with prognosis. On the basis of methodological quality, studies on depression showed mixed results, no conclusions could be drawn for anxiety because this association was not investigated soundly, and the quality of the social network was not associated with outcome. CONCLUSION Evidence suggests that depressive symptoms and social support might be associated with prognosis in CHF outpatients, independently of biomedical risk factors. With respect to anxiety, no conclusions can be drawn. Future studies are warranted to disentangle associations with psychological factors.

Abstract
Heart failure affects millions of Americans and new diagnosis rates are expected to almost triple over the next 30 years as our population ages. Affective disorders including clinical depression and anxiety are common in patients with congestive heart failure. Furthermore, the presence of these disorders significantly impacts quality of life, medical outcomes, and healthcare service utilization. In recent years, the literature has attempted to describe potential pathophysiologic mechanisms relating affective disorders and psychosocial stress to heart failure. Several potential mechanisms have been proposed including autonomic nervous system dysfunction, inflammation, cardiac arrhythmias, and altered platelet function. These mechanisms are reviewed in this article. Additional novel mechanisms such as mental stress-induced myocardial ischemia are also discussed.

Pacific Islanders' perspectives on heart failure management. PATIENT EDUCATION AND COUNSELING 2008; 70:281-91.

Abstract
OBJECTIVE To identify the health beliefs, attitudes, practices, and social and family relations important in heart failure treatment among Pacific Islanders. METHODS Four focus groups were convened with 36 Native Hawaiians and Samoans with heart failure and their family caregivers. Thematic data analysis was used to categorize data into four domains: health beliefs and attitudes, preferred health practices, social support systems, and barriers to heart failure care. RESULTS Common coping styles and emotional experiences of heart failure in this population included avoidance or denial of illness, hopelessness and despair, and reliance on spiritual/religious beliefs as a means of support. Among study participants, more Samoans preferred to be treated by physicians whereas more Native Hawaiians preferred traditional Hawaiian methods of healing. Two types of social support (informational and tangible-instrumental) were identified as important in heart failure care. Barriers to heart failure care included poor knowledge of heart failure, lack of trust in physicians' care, poor physician-patient relations, finances, dietary changes, and competing demands on time. CONCLUSION The recruitment, retention, and adherence of Pacific Islanders to heart failure interventions is affected by an array of psychosocial and socio-cultural factors. PRACTICE IMPLICATIONS Interventions might be improved by offering participants accurate and detailed information about heart failure and its treatment, engaging the extended family in providing necessary supports, and providing tools to facilitate physician-patient relationships, among others, within the context of a larger socio-cultural system.

Abstract
An important component of psychoneuroimmunology research is to reveal the myriad ways that behaviors and health are inter-related, with a focus on the immunological mechanisms that underlie these interactions. Research in human psychoneuroimmunology has shown that immunoregulatory processes are an integral part of a complex network of adaptive responses. As such, this review provides a perspective from our laboratory over the last 20 years to define the inter-relationships between behavior and immunity; to identify the hypothalamic pituitary adrenal (HPA) and autonomic mechanisms that link the central nervous system and immune responses; to examine the clinical implications of immune alterations during depression or life stress on inflammatory and infectious disease risk; and to explore the reciprocal role of immune mediators on behavior in humans.

Abstract
Symptoms utilized in the clinical care of heart failure as markers of disease severity include, dyspnea, insomnia, low energy, fatigue, poor appetite, and diminished memory. This is despite the fact that physiologic variables such as cardiac ejection fraction and oxygen consumption do not accurately predict functional state in individuals with congestive heart failure (CHF). Distress (anxiety and depression) may amplify symptom complaints without associated physiologic aberration. Personality traits and psychiatric illness, such as mood, anxiety, and psychotic illnesses may also alter perception of somatic symptoms that are associated with this chronic illness. The impact of distress and its treatment on functional performance and CHF symptom reporting deserve additional attention. The need to screen for distress in all with serious symptomatic heart failure is certain.
