Background: Depression is more common in females than in males and is 3-5 times more prevalent in patients with heart failure (HF) than in the general population. The 9-item Patient Health Questionnaire (PHQ-9) is a validated depression screening instrument; higher sum-scores predict adverse clinical outcomes. Sex- and gender differences in PHQ-9 symptom profile, diagnostic and prognostic properties, and impact on health-related quality of life (HRQOL) have not been comprehensively studied in HF patients., Methods and Results: This post hoc analysis from the Interdisciplinary Network Heart Failure program enrolled 852/1022 participants (67 ± 13 years, 28% female) who completed the PHQ-9 at hospital discharge after cardiac decompensation. All had a left ventricular ejection fraction ≤ 40%. Women had a higher mean PHQ-9 sum-score than men (8.4 ± 5.6 vs. 7.4 ± 5.5; p = 0.027), and higher proportions rated the following items ≥ 2 (i.e., present on ≥ 50% of days): 'feeling down, hopeless' (25.8 vs. 18.0%; p = 0.011); 'fatigue' (51.9 vs. 37.2%; p < 0.001); and 'trouble concentrating' (21.6 vs. 15.4%; p = 0.032). A PHQ-9 sum-score ≥ 10 predicted increased mortality in women [hazard ratio 1.91 (95% confidence interval 1.06-3.43); p = 0.030] and men [2.10 (1.43-3.09); p < 0.001] and was associated with worse HRQOL (p < 0.001 for all comparisons). Sum-scores ≥ 10 predicted higher re-hospitalization rates in men only [1.35 (1.08-1.69); p = 0.008]., Conclusions: Differences in several PHQ-9 items indicated sex- or gender-specific depression symptomatology in HF. For both sexes, HRQOL and survival were worse when PHQ-9 sum-score was ≥ 10, but higher sum-scores predicted higher re-hospitalization rates in men only. Considering these specific aspects might help optimize care strategies in HF.

Purpose of Review: Depression, anxiety, and cognitive impairment constitute established risk markers for incident cardiovascular disease (CVD) and are associated with impaired life expectancy and quality of life and high hospitalization rates and healthcare expenditure. This review summarizes current knowledge about mental health disorders in patients with CVD and heart failure (HF)., Recent Findings: Emerging evidence suggests various shared pathophysiological mechanisms between psychological comorbidities and CVD (e.g., systemic inflammation and autonomic dysfunction). Bi-directional interactions involving the central nervous and cardiovascular systems may help explain the rising prevalence of comorbid mood disorders with increasing CVD severity and support the concept of alternative pathophysiological mechanisms in the presence of severe somatic illness, making symptoms less responsive or unresponsive to psychotropic pharmacotherapy. Considering high prevalence and negative impact of psychological comorbidities in CVD and HF, routine care should integrate screening for these conditions. Multidisciplinary treatment approaches with active patient participation in disease management were shown to improve outcomes. However, better understanding of factors mediating the adverse prognostic effects of mood disorders is needed. This might enable more targeted treatment and possibly also facilitate better understanding of the pathophysiological mechanisms driving CVD.

Heart failure and depression are widespread diseases and of particular clinical and economic relevance. Compared with the general population depression is up to 5‑times more common in patients with heart failure, with adverse effects on morbidity, mortality, quality of life and treatment costs. Depressive symptoms overlap with those of heart failure which renders diagnosis difficult. Simple screening tools, e. g. the two-item patient health questionnaire, help to recognize depression in the clinical routine. To date, there is no evidence that antidepressant pharmacotherapy improves mood and clinical outcomes in patients with heart failure and comorbid depression and antidepressant pharmacotherapy remains to be decided on a case by case basis; however, physical training, cognitive behavioral therapy and multidisciplinary comprehensive disease management improved symptoms and/or prognosis in a limited number of randomized studies.

Depression is common in heart failure and associated with impaired quality of life. It impacts adversely on clinical outcomes. Both diseases are widespread in the general population with increasing prevalence and treatment costs. They are therefore also of socio-economic relevance. Various interrelated biological and behavioral factors (e.g. lower treatment adherence in depressed patients with heart failure) seem to play a pathophysiological role, and there is growing evidence that both diseases may also share genetic susceptibilities. Simple screening tools ease depression diagnosis in clinical practice, although the clinical profile of both disorders overlaps. To date, there is no evidence that antidepressant pharmacotherapy improves depressive symptoms, mortality and morbidity in patients with heart failure and comorbid depression, but physical training, cognitive behavioral therapy and comprehensive disease management improved symptoms and/or prognosis in individual randomized studies., (© Georg Thieme Verlag KG Stuttgart · New York.)

Importance: Depression is frequent in patients with heart failure and is associated with adverse clinical outcomes. Long-term efficacy and safety of selective serotonin reuptake inhibitors in these patients are unknown., Objective: To determine whether 24 months of treatment with escitalopram improves mortality, morbidity, and mood in patients with chronic systolic heart failure and depression., Design, Setting, and Participants: The Effects of Selective Serotonin Re-Uptake Inhibition on Morbidity, Mortality, and Mood in Depressed Heart Failure Patients (MOOD-HF) study was a double-blind, placebo-controlled randomized clinical trial conducted at 16 tertiary medical centers in Germany. Between March 2009 and February 2014, patients at outpatient clinics with New York Heart Association class II-IV heart failure and reduced left ventricular ejection fraction (<45%) were screened for depression using the 9-item Patient Health Questionnaire. Patients with suspected depression were then invited to undergo a Structured Clinical Interview based on the Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition) to establish the diagnosis., Interventions: Patients were randomized 1:1 to receive escitalopram (10-20 mg) or matching placebo in addition to optimal heart failure therapy. Study duration was 24 months., Main Outcomes and Measures: The composite primary outcome was time to all-cause death or hospitalization. Prespecified secondary outcomes included safety and depression severity at 12 weeks of treatment (including the titration period), which were determined using the 10-item Montgomery-Åsberg Depression Rating Scale (total possible score, 0 to 60; higher scores indicate more severe depression)., Results: A total of 372 patients (mean age, 62 years; 24% female) were randomized and had taken at least 1 dose of study medication when the data and safety monitoring committee recommended the trial be stopped early. During a median participation time of 18.4 months (n = 185) for the escitalopram group and 18.7 months (n = 187) for the placebo group, the primary outcome of death or hospitalization occurred in 116 (63%) patients and 119 (64%) patients, respectively (hazard ratio, 0.99 [95% CI, 0.76 to 1.27]; P = .92). The mean Montgomery-Åsberg Depression Rating Scale sum score changed from 20.2 at baseline to 11.2 at 12 weeks in the escitalopram group and from 21.4 to 12.5 in the placebo group (between-group difference, -0.9 [95% CI,-2.6 to 0.7]; P = .26). Safety parameters were comparable between groups., Conclusions and Relevance: In patients with chronic heart failure with reduced ejection fraction and depression, 18 months of treatment with escitalopram compared with placebo did not significantly reduce all-cause mortality or hospitalization, and there was no significant improvement in depression. These findings do not support the use of escitalopram in patients with chronic systolic heart failure and depression., Trial Registration: isrctn.com Identifier: ISRCTN33128015.

Objective: The prognostic potential of depressive symptoms independent of somatic features of heart failure severity has repeatedly been demonstrated. However, patient-reported functional status has rarely been accounted for in these studies. Thus, it has remained unclear to what extent the predictive power of depressive symptoms may mirror functional status. We therefore aimed to evaluate the prognostic value of depressive symptoms adjusting for patient-reported functional status in a large, well-characterized sample of patients with systolic heart failure., Methods: Eight hundred sixty-three patients, 67±12 years old, 72% men, and 42% with New York Heart Association functional classes III/IV, who participated in the extended Interdisciplinary Network Heart Failure (INH) study were investigated. We assessed depressive symptoms using the Patient Health Questionnaire (PHQ-9) and patient-reported functional status with the Kansas City Cardiomyopathy Questionnaire (KCCQ). Data on survival was obtained after a follow-up of 18 months (100% complete)., Results: Depressive symptoms predicted mortality risk (HR per PHQ-9 scale point=1.07, 95% CI 1.04-1.09, p<.001), even after adjustment for heart failure severity and co-morbidities (HR=1.04, 95% CI 1.01-1.07, p=.017). However, they were no longer significant predictors (HR=1.01, 95% CI 0.98-1.05, p=0.46) after additional adjustment for patient-reported functional status, which proved predictive of mortality risk (HR=0.90, 95% CI 0.82-0.99, p=.025)., Conclusion: Our results suggest that the association of depressive symptoms with functional status may at least partly explain the prognostic potential of depressive symptoms., (Copyright © 2015 Elsevier Inc.

Background: Depression is common in heart failure and associated with adverse clinical outcomes. We investigated the potential of the 2-item patient health questionnaire (PHQ-2) versus that of the 9-item version (PHQ-9) to predict death or rehospitalization., Methods and Results: Participants of the Interdisciplinary Network for Heart Failure program were eligible, if they completed the PHQ-9 during baseline assessment. All participants were hospitalized for cardiac decompensation and had a left ventricular ejection fraction ≤40% before discharge. PHQ-2 scores were extracted from the answers to the first 2 PHQ-9 questions. To analyze associations of PHQ-2 and PHQ-9 with both, death and rehospitalization, univariable Cox regression models were used. To compare screening efficacy of both tools, c-statistics were computed. The sample consisted of 852 patients, (67.6±12.1 years; 27.7% women; 42.3% New York Heart Association class III/IV). Follow-up was 18 months (100% complete). During follow-up, 152 patients died and 482 were rehospitalized. Both, PHQ-2 and PHQ-9, predicted death in univariable analysis (hazard ratio, 1.18; 95% confidence interval, 1.09-1.29; P<0.001 and hazard ratio, 1.07; 95% confidence interval, 1.04-1.09; P<0.001, respectively), as well as rehospitalization (hazard ratio, 1.07; confidence interval, 1.01-1.21; P=0.02 and hazard ratio, 1.03; confidence interval, 1.01-1.04; P=0.001, respectively). These results were confirmed by c-statistics., Conclusions: In univariable models and confirmed by c-statistics the potential of both PHQ-2 and PHQ-9 to predict death and hospitalization was similar. In clinical practice, PHQ-2 screening seems thus sufficiently reliable and more feasible than the time-consuming PHQ-9 to identify patients at an increased risk of adverse outcomes., Clinical Trial Registration: URL: http://www.controlled-trials.com.

Aims: Depression is common in heart failure (HF) and associated with adverse outcomes. Randomized comparisons of the effectiveness of HF care strategies by patients' mood are scarce. We therefore investigated in a randomized trial a structured collaborative disease management programme (HeartNetCare-HF™; HNC) recording mortality, morbidity, and symptoms in patients enrolled after hospitalization for decompensated systolic HF according to their responses to the 9-item Patient Health Questionnaire (PHQ-9) during an observation period of 180 days., Methods and Results: Subjects scoring <12/≥12 were categorized as non-depressed/depressed, and those ignoring the questionnaire as PHQ-deniers. Amongst 715 participants (69 ± 12 years, 29% female), 141 (20%) were depressed, 466 (65%) non-depressed, and 108 (15%) PHQ-deniers. The composite endpoint of mortality and re-hospitalization was neutral overall and in all subgroups. However, HNC reduced mortality risk in both depressed and non-depressed patients [adjusted hazard ratios (HRs) 0.12, 95% confidence interval (CI) 0.03-0.56, P = 0.006, and 0.49, 95% CI 0.25-0.93, P = 0.03, respectively], but not in PHQ-deniers (HR 1.74, 95% CI 0.77-3.96, P = 0.19; P = 0.006 for homogeneity of HRs). Average frequencies of patient contacts in the HNC arm were 12.8 ± 7.9 in non-depressed patients, 12.4 ± 7.1 in depressed patients, and 5.5 ± 7.2 in PHQ-deniers (P < 0.001)., Conclusions: Early after decompensation, HNC reduced mortality risk in non-depressed and even more in depressed subjects, but not in PHQ-deniers. This suggests that differential acceptability and chance of success of care strategies such as HNC might be predicted by appropriate assessment of patients' baseline characteristics including psychological disposition. These post-hoc results should be reassessed by prospective evaluation of HNC in larger HF populations., (© 2014 The Authors. European Journal of Heart Failure © 2014 European Society of Cardiology.)

Heart failure (HF) is highly prevalent and associated with adverse outcomes and high costs. Compared with the general population, depression is up to five times more common in HF patients. Comorbid depression increases morbidity and mortality risk and health-care expenditures even further and decreases quality of life. Possible, often interrelated, mediators of these effects include biological, behavioral, and psychosocial factors. Screening instruments such as the self-administered PHQ-2 facilitate detection of patients at risk. Although antidepressants may improve psychological well-being, no positive effects on hard clinical endpoints have been demonstrated to date.

Aims: Depression is common in heart failure (HF) and associated with adverse outcomes. This study aimed to investigate incidence rates and predictors of depression in patients sampled from four subprojects of the German Competence Network Heart Failure., Methods: Eight hundred thirty nine symptomatic HF patients free of depression at baseline underwent repeat depression screening (Patient Health Questionnaire, PHQ-9) after 12 months. Ordered logistic regression analysis was employed to search for predictors of incident depression., Results: Incident minor (major) depression was observed in 61 (7.3%) and 47 (5.6%) of the population. Depression was recurrent in 15 (25%) and 16 (34%), respectively. Multiple regression analysis revealed seven variables predicting minor or major depression: Previous depressive episode (odds ratio [OR] 4.04, 95% confidence interval [CI] 2.37-6.89, p ≤ 0.001), previous resuscitation (OR 2.44, CI 1.23-4.81, p=0.010), current smoking (OR 2.06, CI 1.08-3.50, p=0.008), >4 visits/year to general practitioner (OR 1.67, CI 1.06-2.63, p=0.026), New York Heart Association class (OR 1.54/class, 95% CI 1.05-2.25, p=0.027), PHQ-9 baseline sum-score (OR 1.18/point, CI 1.11-1.27, p<0.001), and SF-36 physical functioning (OR 1.08/-5 points, CI 1.03-1.13, p=0.002)., Conclusions: In these HF patients initially free of depression annual incidence rates were high. Several independent predictors allowed identification of patients at particular risk. Although obtained in a selected cohort these findings call, in view of the grave prognosis of HF patients with comorbid depression, for regular depression screening and development of specific supportive strategies to improve patient care and outcomes in HF., (Copyright © 2012 Elsevier Ireland Ltd.

Aims: Heart failure is known to profoundly affect health-related quality of life (HRQoL). We aimed to describe both generic and disease-specific HRQoL in a large community-based sample of patients with systolic heart failure (SHF) and to identify important somatic and psychosocial correlates., Methods and Results: Seven hundred and two patients, 67 ± 12 years old, 71 % men, with distributions of New York Heart Association (NYHA) functional classes I/II/III/IV of 2/55/39/4 % were included in this cross-sectional analysis. Generic HRQoL was measured with the SF-36 health survey, disease-specific HRQoL with the Kansas City Cardiomyopathy Questionnaire, and depression with the self-reported Patient Health Questionnaire (PHQ-9). Both generic- and disease-specific HRQoL measurements indicated moderate to poor HRQoL. The KCCQ scores demonstrated higher sensitivity to the varying levels of heart failure severity as compared to the SF-36 scores. Patients with either a minor (15 %) or a major depression (24 %) reported significantly and substantially lower HRQoL (p < .001) than patients without depression did. In multivariable regression analyses, depression accounted for the largest part of the variance of both generic and specific HRQoL (12 and 36 %, respectively), whereas most biomedical variables had no or only a marginal influence., Conclusion: Patients with SHF suffer from severe limitations of HRQoL. Depression was the most important correlate of both generic and disease-specific HRQoL.

Background: Depression and chronic heart failure (CHF) are common conditions, both of which are clinically and economically highly relevant. Major depression affects 20-40% of CHF patients and predicts adverse outcomes in terms of quality of life, morbidity and mortality as well as health care expenditure, independent of other factors of prognostic relevance., Aims: The purpose of the MOOD-HF trial is to clarify whether antidepressant pharmacotherapy improves outcome in CHF patients, and if so by which mechanism(s)., Methods: MOOD-HF is a prospective, randomised, double-blind, placebo-controlled, 2-armed, parallel-group multicenter trial investigating the effects of the serotonin re-uptake inhibitor (SSRI) escitalopram on morbidity and mortality (primary endpoint), severity of depression, anxiety, cognitive function, quality of life and health care expenditure in 700 patients with symptomatic systolic CHF and major depression diagnosed by structured clinical interview. All patients will receive optimised pharmacotherapy for CHF. Duration of follow-up, including close safety monitoring, is 12-24 months from randomisation., Perspective: MOOD-HF is the first prospective randomised controlled trial to assess the effects of antidepressant pharmacotherapy on hard somatic endpoints, the mechanism(s) of action of SSRI treatment, as well as safety in New York Heart Association functional class II-IV CHF patients. The results are expected to promote the development of evidence-based recommendations for managing depression in the context of CHF., Trial Registration: (ISRCTN.org). Identifier: ISRCTN33128015.
