Mortality Risk Among Heart Failure Patients With Depression: A Nationwide Population-Based Cohort Study

Predicting depression in patients with heart failure based on a stacking model

BACKGROUND

There is a lack of literature discussing the utilization of the stacking ensemble algorithm for predicting depression in patients with heart failure (HF).

AIM

To create a stacking model for predicting depression in patients with HF.

METHODS

This study analyzed data on 1084 HF patients from the National Health and Nutrition Examination Survey database spanning from 2005 to 2018. Through univariate analysis and the use of an artificial neural network algorithm, predictors significantly linked to depression were identified. These predictors were utilized to create a stacking model employing tree-based learners. The performances of both the individual models and the stacking model were assessed by using the test dataset. Furthermore, the SHapley additive exPlanations (SHAP) model was applied to interpret the stacking model.

RESULTS

The models included five predictors. Among these models, the stacking model demonstrated the highest performance, achieving an area under the curve of 0.77 (95%CI: 0.71-0.84), a sensitivity of 0.71, and a specificity of 0.68. The calibration curve supported the reliability of the models, and decision curve analysis confirmed their clinical value. The SHAP plot demonstrated that age had the most significant impact on the stacking model's output.

CONCLUSION

The stacking model demonstrated strong predictive performance. Clinicians can utilize this model to identify high-risk depression patients with HF, thus enabling early provision of psychological interventions.

Recurrent heart failure hospitalizations in heart failure with preserved ejection fraction: an analysis of TOPCAT trial

AIMS

Recurrent heart failure hospitalization (HFH) is an important feature of the progression of heart failure (HF). In the Treatment of Preserved Cardiac Function Heart Failure with an Aldosterone Antagonist (TOPCAT) trial, we analysed risk factors for recurrent HFH events in HF patients with preserved ejection fraction (HFpEF) and developed a risk prediction model for recurrent HFH.

METHODS AND RESULTS

This analysis focused on the subset of TOPCAT participants enrolled in the Americas (n = 1767). Recurrent HFH was defined as two or more hospitalizations for HF during the follow-up period. Lasso regression and multivariate logistic regression were used to screen the risk factors, and the risk prediction model of recurrent HFH was established. During a median follow-up period of 3.4 (95% confidence interval: 3.3-3.6) years, 72.2% (542 of 751 total hospitalizations) of HFH events occurred in 9.4% (n = 163) of patients with recurrent HFHs. Patients in the recurrent HFH group had higher cardiovascular mortality rate [6.2 per 100 patient-years (PY) vs. 3.8 per 100 PY, P = 0.016] and all-cause mortality rate (10.0 per 100 PY vs. 6.8 per 100 PY, P = 0.015) than those in the non-recurrent HFH group. The model consisting of nine predictors has moderate predictive power for recurrent HFH events in patients with HFpEF (AUC = 0.75, Brier score = 0.08). Decision curve analysis showed a net clinical benefit from the application of the prediction model.

CONCLUSIONS

In patients with HFpEF, the majority of HFHs occur in a small proportion of patients with repeated hospitalizations, who typically have more comorbidities and are at higher risk of death. The predictive model developed in this study helps to identify patients at high risk of recurrent HFH.

Incidence of depression in patients with cardiovascular disease and type 2 diabetes: a nationwide cohort study

BACKGROUND

Estimating how type 2 diabetes (T2D) affects the rate of depression in cardiovascular disease (CVD) can help identify high-risk patients. The aim is to investigate how T2D affects the rate of depression according to specific subtypes of CVD.

METHODS

Incident CVD patients, free of psychiatric disease, with and without T2D, were included from nationwide registries between 2010 and 2020. We followed patients from CVD diagnosis until the first occurrence of depression, emigration, death, 5 years, or end of study (December 31, 2021). We used time-dependent Poisson regression to estimate the incidence rates and rate ratios (IRR) of depression following subtypes of CVD with and without T2D. The model included age, sex, comorbidities, calendar year, T2D duration, educational level, and living situation as covariates.

RESULTS

A total of 165,096 patients were included; 45,845 had a myocardial infarction (MI), 63,691 had a stroke, 19,959 had peripheral artery disease (PAD), 35,568 had heart failure (HF), and 979 were diagnosed with 2 or more CVD subtypes (= > 2 CVD's). Baseline T2D in each CVD subtype ranged from 11 to 17%. The crude incidence rate of depression per 1000 person-years (95% confidence intervals) was: MI + T2D: 131.1 (109.6;155.6), MI: 82.1 (65.3;101.9), stroke + T2D: 287.4 (255.1;322.6), stroke: 222.4(194.1;253.6), PAD + T2D: 173.6 (148.7;201.4), PAD:137.5 (115.5;162.5), HF + T2D: 244.3 (214.6;276.9), HF: 199.2 (172.5;228.9), =  > 2 CVD's + T2D: 427.7 (388.1;470.2), =  > 2 CVD's: 372.1 (335.2;411.9). The adjusted IRR of depression in MI, stroke, PAD, HF, and =  > 2 CVD's with T2D compared to those free of T2D was: 1.29 (1.23;1.35), 1.09 (1.06;1.12), 1.18 (1.13;1.24), 1.05 (1.02;1.09), and 1.04 (0.85;1.27) (p-value for interaction < 0.001).

CONCLUSION

The presence of T2D increased the rate of depression differently among CVD subtypes, most notable in patients with MI and PAD.

Treatment of depression and inadequate self-care in patients with heart failure: One-year outcomes of a randomized controlled trial

OBJECTIVE

Both depression and inadequate self-care are common in patients with heart failure. This secondary analysis examines the one-year outcomes of a randomized controlled trial of a sequential approach to treating these problems.

METHODS

Patients with heart failure and major depression were randomly assigned to usual care (n = 70) or to cognitive behavior therapy (n = 69). All patients received a heart failure self-care intervention starting 8 weeks after randomization. Patient-reported outcomes were assessed at Weeks 8, 16, 32, and 52. Data on hospital admissions and deaths were also obtained.

RESULTS

One year after randomization, Beck Depression Inventory (BDI-II) scores were - 4.9 (95% C.I., -8.9 to -0.9; p < .05) points lower in the cognitive therapy than the usual care arm, and Kansas City Cardiomyopathy scores were 8.3 (95% C.I., 1.9 to 14.7; p < .05) points higher. There were no differences on the Self-Care of Heart Failure Index or in hospitalizations or deaths.

CONCLUSIONS

The superiority of cognitive behavior therapy relative to usual care for major depression in patients with heart failure persisted for at least one year. Cognitive behavior therapy did not increase patients' ability to benefit from a heart failure self-care intervention, but it did improve HF-related quality of life during the follow-up period.

Experiences with cross-sectional healthcare and treatment in heart failure patients: implications for medical education

Objectives

to explore how cross-sectional healthcare and treatment is experienced a) by patients with advanced heart failure and multimorbidity and b) by hospital-employed healthcare professionals.

Methods

Individual telephone interviews with 18 patients and close relatives were conducted. Furthermore, a focus group session was conducted with four specialised hospital-employed healthcare professionals. Purposeful sampling was used and interviews were semi-structured. Data were analysed using qualitative inductive content analysis.

Results

Three main themes emerged from the interviews with patients and close relatives. These included: 1) A need for improved coordination to ensure continuity of care; 2) a plea for patient-centred care; and 3) recognition of the need to care for close relatives. Analysis of the interviews with hospital-employed healthcare professionals also produced three themes. These concerned: 1) recognition of the role and needs of close relatives; 2) limited resources for and difficulties in meeting these needs; and 3) agreement on the need for patient-centred care. Furthermore, we learned that perceived challenges are rooted in time constraints and the need for an adequate level of medical knowledge of chronic conditions and complex treatment strategies.

Conclusions

This study indicates that cross-sectional healthcare and treatment of patients with advanced heart failure and multimorbidity lacked coordination, was insufficiently patient-centred and did not cater for close relatives' needs. The study identifies patient-centredness and coordination of healthcare services targeting patients and close relatives alike as critical to proper care, medical curriculum development and continued medical training courses.

Relationship between mutuality and depression in patients with chronic heart failure and caregivers in China: An actor-partner interdependence model analysis

Background

Patients with chronic heart failure and their family caregivers may experience adverse emotional problems, such as depression. Mutuality, which refers to the relationship between caregivers and those they care for, is an important factor affecting depression in the dyads. The purpose of this study was to investigate the relationship between mutuality and depression in patients with CHF and their caregivers in China.

Methods

In this cross-sectional study, we used the Mutuality Scale and the Self-Rating Depression Scale to measure mutuality and depression of patients and caregivers. We used SPSS version 26.0 and AMOS version 21.0 to analyze the data. An APIM was established to analyze the actor-partner effects of patient-caregiver mutuality and depression.

Results

A total of 250 dyads of patients and caregivers were included in the study. There were statistically significant differences in mutuality and depression between CHF patients and caregivers. The 4 dimensions of patients' mutuality all have the actor effect on depression. There were 3 partner effects of caregivers' "pleasurable activities", "shared values", and "reciprocity" on depression. Regarding caregiver depression, we only found an actor effect of caregivers' "shared values" on depression.

Conclusion

The relationship between patients and caregivers should be evaluated in the clinical setting, and it is very important to develop intervention measures to improve the adverse emotional problems affecting both patients and their caregivers.

Depressive symptoms, cognitive impairment, and all-cause mortality among REGARDS participants with heart failure

Aims

To ascertain whether depressive symptoms and cognitive impairment (CI) are associated with mortality among patients with heart failure (HF), adjusting for sociodemographic, comorbidities, and biomarkers.

Methods and results

We utilized Medicare-linked data from the Reasons for Geographic and Racial Differences in Stroke (REGARDS) Study, a biracial prospective ongoing cohort of 30 239 US community-dwelling adults, recruited in 2003-07. HF diagnosis was ascertained in claims analysis. Depressive symptoms were defined as a score ≥4 on the four-item Center for Epidemiological Studies-Depression scale. Cognitive impairment was defined as a score of ≤4 on the six-item screener that assessed three-item recall and orientation to year, month, and day of the week. Sequentially adjusted Cox proportional hazard models were used to estimate the risk of death. We analyzed 1059 REGARDS participants (mean age 73, 48%-African American) with HF; of those 146 (14%) reported depressive symptoms, 136 (13%) had CI and 31 (3%) had both. Over the median follow-up of 6.8 years (interquartile range, 3.4-10.3), 785 (74%) died. In the socio-demographics-adjusted model, CI was significantly associated with increased mortality, hazard ratio 1.24 (95% confidence interval 1.01-1.52), compared with persons with neither depressive symptoms nor CI, but this association was attenuated after further adjustment. Neither depressive symptoms alone nor their comorbidity with CI was associated with mortality. Risk factors of all-cause mortality included: low income, comorbidities, smoking, physical inactivity, and severity of HF.

Conclusion

Depressive symptoms, CI, or their comorbidity was not associated with mortality in HF in this study. Treatment of HF in elderly needs to be tailored to cognitive status and includes focus on medical comorbidities.

Sequential Interventions for Major Depression and Heart Failure Self-Care: A Randomized Clinical Trial

BACKGROUND

Major depression and inadequate self-care are common in patients with heart failure (HF). Little is known about how to intervene when both problems are present. This study examined the efficacy of a sequential approach to treating these problems.

METHODS

Stepped Care for Depression in HF was a single-site, single-blind, randomized controlled trial of cognitive behavior therapy (CBT) versus usual care (UC) for major depression in patients with HF. The intensive phase of the CBT intervention lasted between 8 and 16 weeks, depending upon the rate of improvement in depression. All participants received a tailored HF self-care intervention that began 8 weeks after randomization. The intensive phase of the self-care intervention ended at 16 weeks post-randomization. The coprimary outcome measures were the Beck Depression Inventory (version 2) and the Maintenance scale of the Self-Care of HF Index (v6.2) at week 16.

RESULTS

One hundred thirty-nine patients with HF and major depression were enrolled; 70 were randomized to UC and 69 to CBT. At week 16, the patients in the CBT arm scored 4.0 points ([95% CI, -7.3 to -0.8]; P=0.02) lower on the Beck Depression Inventory, version 2 than those in the usual care arm. Mean scores on the Self-Care of HF Index Maintenance scale were not significantly different between the groups ([95% CI, -6.5 to 1.5]; P=0.22).

CONCLUSIONS

CBT is more effective than usual care for major depression in patients with HF. However, initiating CBT before starting a tailored HF self-care intervention does not increase the benefit of the self-care intervention.

Risk of Parkinson Disease and Secondary Parkinsonism in Myocardial Infarction Survivors

Background

In addition to primary neurodegenerative processes, vascular disorders, such as stroke, can lead to parkinsonism. However, some cardiovascular risk factors, such as smoking and elevated cholesterol levels, are associated with reduced risk of Parkinson disease. We examined the risk of Parkinson disease and secondary parkinsonism in 1‐year survivors of myocardial infarction (MI).

Methods and Results

We conducted a nationwide population‐based matched cohort study using Danish medical registries from 1995 to 2016. We identified all patients with a first‐time MI diagnosis and sampled a sex‐, age‐, and calendar year–matched general population comparison cohort without MI. Cox regression analysis was used to compute adjusted hazard ratios (aHRs) for Parkinson disease and secondary parkinsonism, controlled for matching factors and adjusted for relevant comorbidities and socioeconomic factors. We identified 181 994 patients with MI and 909 970 matched comparison cohort members (median age, 71 years; 62% men). After 21 years of follow‐up, the cumulative incidence was 0.9% for Parkinson disease and 0.1% for secondary parkinsonism in the MI cohort. Compared with the general population cohort, MI was associated with a decreased risk of Parkinson disease (aHR, 0.80; 95% CI, 0.73–0.87) and secondary parkinsonism (aHR, 0.72; 95% CI, 0.54–0.94).

Conclusions

MI was associated with a 20% decreased risk of Parkinson disease and 28% decreased risk of secondary parkinsonism. Reduced risk may reflect an inverse relationship between cardiovascular risk factors and Parkinson disease.

Association of Major Depressive Disorder on Heart Failure With Reduced and Preserved Ejection Fraction: Analysis of National Readmission Database 2018

Introduction

The effect of major depressive disorder (MDD) on heart failure types is unclear. We aimed to assess the association of depression in heart failure with preserved ejection fraction (HFpEF) and heart failure with reduced ejection fraction (HFrEF) readmissions using the Nationwide Readmission Database (NRD) 2018. 

Methods 

We identified hospitalizations with a primary discharge diagnosis of HFrEF and HFpEF by appropriate ICD-10-CM codes. We acquired mortality and readmission data with and without MDD at 30 days. We used multivariate logistic regression analysis to estimate the adjusted odds ratio (aOR).

Results 

Among 102,997 patients admitted with heart failure as a primary diagnosis, 11% had MDD. We found a similar prevalence of HFpEF with MDD compared to HFrEF at 13.9% and 10%, respectively. Both HFrEF and HFpEF patients with MDD had similar combined outcomes of 30-day mortality and rehospitalization compared to patients without MDD with aOR 0.94 (95% CI: 0.85-1.04) and 0.93 (95% CI: 0.81-1.07), respectively. Both types of HF with MDD were associated with lesser mortality.

Conclusion

MDD was associated with similar combined 30-day mortality and readmissions for both HFrEF and HFpEF. However, MDD was associated with decreased 30-day mortality in both groups of heart failure (HF) patients. Further studies with robust medications and treatment data are needed to verify the results of our study.

Impact of Age on Comorbidities and Outcomes in Heart Failure With Reduced Ejection Fraction

OBJECTIVES

This study sought to determine whether age modifies the impact of key comorbidities on clinical outcomes for patients with heart failure with reduced ejection fraction (HFrEF).

BACKGROUND

Comorbidities impact outcomes in HFrEF. However, the effect of age on the impact of comorbidities on prognosis is not clearly understood.

METHODS

Cox proportional hazards models were used assessed interactions between age and comorbidities on the primary composite endpoint (all-cause mortality or hospitalization) and secondary endpoints in the HF-ACTION (Heart Failure: A Controlled Trial Investigating Outcomes of Exercise Training) multicenter trial of 2,331 patients with HFrEF.

RESULTS

Age did not significantly modify the effect of any comorbidity on the primary endpoint. However, age significantly modified the effect of body mass index (BMI) on all-cause mortality (interaction p = 0.02). Among patients ≥70 years of age, there was a U-shaped relationship between BMI and 1-year mortality, where BMI of 20 kg/m² corresponded to 17.6%; a BMI of 30 kg/m² corresponded to 7.0%; and a BMI of 40 kg/m² corresponded to 11%. For patients <60 years of age, mortality increased nonsignificantly from 3.2% to 3.7% with increasing BMI. Age also modified the effect of depressive symptoms on all-cause mortality (interaction p = 0.03). Among patients ≥70 years of age, a 1-year mortality rate significantly increased from 7.8% for a Beck Depression Inventory (BDI) score of 5% to 15.6% for BDI of 20. For patients <60 years of age, mortality was nonsignificantly related to BDI. Cumulative comorbidity scores were stronger predictors than age for mortality/hospitalization.

CONCLUSIONS

In chronic HFrEF, age markedly altered the impact of BMI and depressive symptoms on all-cause mortality, with much higher risk in older patients, but was not as strong a predictor of mortality/hospitalizations as cumulative comorbidity score.

Interoception, Stress, and Physical Symptoms in Stress-Associated Diseases

Abstract. The brain and peripheral bodily organs continuously exchange information. Exemplary, interoception refers to the processing and perception of ascending information from the body to the brain. Stress responses involve a neurobehavioral cascade, which includes the activation of peripheral organs via neural and endocrine pathways and can thus be seen as an example for descending information on the brain-body axis. Hence, the interaction of interoception and stress represents bi-directional communication on the brain-body axis. The main hypothesis underlying this review is that the dysregulation of brain-body communication represents an important mechanism for the generation of physical symptoms in stress-related disorders. The aims of this review are, therefore, (1) to summarize current knowledge on acute stress effects on different stages of interoceptive signal processing, (2) to discuss possible patterns of abnormal brain-body communication (i.e., alterations in interoception and physiological stress axes activation) in mental disorders and chronic physical conditions, and (3) to consider possible approaches to modify interoception. Due to the regulatory feedback loops underlying brain-body communication, the modification of interoceptive processes (ascending signals) may, in turn, affect physiological stress axes activity (descending signals), and, ultimately, also physical symptoms.

Association of Symptoms of Depression With Cardiovascular Disease and Mortality in Low-, Middle-, and High-Income Countries

IMPORTANCE

Depression is associated with incidence of and premature death from cardiovascular disease (CVD) and cancer in high-income countries, but it is not known whether this is true in low- and middle-income countries and in urban areas, where most people with depression now live.

OBJECTIVE

To identify any associations between depressive symptoms and incident CVD and all-cause mortality in countries at different levels of economic development and in urban and rural areas.

DESIGN, SETTING, AND PARTICIPANTS

This multicenter, population-based cohort study was conducted between January 2005 and June 2019 (median follow-up, 9.3 years) and included 370 urban and 314 rural communities from 21 economically diverse countries on 5 continents. Eligible participants aged 35 to 70 years were enrolled. Analysis began February 2018 and ended September 2019.

EXPOSURES

Four or more self-reported depressive symptoms from the Short-Form Composite International Diagnostic Interview.

MAIN OUTCOMES AND MEASURES

Incident CVD, all-cause mortality, and a combined measure of either incident CVD or all-cause mortality.

RESULTS

Of 145 862 participants, 61 235 (58%) were male and the mean (SD) age was 50.05 (9.7) years. Of those, 15 983 (11%) reported 4 or more depressive symptoms at baseline. Depression was associated with incident CVD (hazard ratio [HR], 1.14; 95% CI, 1.05-1.24), all-cause mortality (HR, 1.17; 95% CI, 1.11-1.25), the combined CVD/mortality outcome (HR, 1.18; 95% CI, 1.11-1.24), myocardial infarction (HR, 1.23; 95% CI, 1.10-1.37), and noncardiovascular death (HR, 1.21; 95% CI, 1.13-1.31) in multivariable models. The risk of the combined outcome increased progressively with number of symptoms, being highest in those with 7 symptoms (HR, 1.24; 95% CI, 1.12-1.37) and lowest with 1 symptom (HR, 1.05; 95% CI, 0.92 -1.19; P for trend < .001). The associations between having 4 or more depressive symptoms and the combined outcome were similar in 7 different geographical regions and in countries at all economic levels but were stronger in urban (HR, 1.23; 95% CI, 1.13-1.34) compared with rural (HR, 1.10; 95% CI, 1.02-1.19) communities (P for interaction = .001) and in men (HR, 1.27; 95% CI, 1.13-1.38) compared with women (HR, 1.14; 95% CI, 1.06-1.23; P for interaction < .001).

CONCLUSIONS AND RELEVANCE

In this large, population-based cohort study, adults with depressive symptoms were associated with having increased risk of incident CVD and mortality in economically diverse settings, especially in urban areas. Improving understanding and awareness of these physical health risks should be prioritized as part of a comprehensive strategy to reduce the burden of noncommunicable diseases worldwide.

Antidepressant use in patients with heart failure

OBJECTIVE

There is little evidence that antidepressants are efficacious for depression in patients with heart failure (HF), and equivocal evidence that they are safe. This study identified characteristics that are associated with antidepressant use in hospitalized patients with HF.

METHOD

Logistic regression models were used to identify independent correlates of antidepressant use in 400 patients hospitalized with HF between 2014 and 2016. The measure of depression in the primary analysis was a DSM-5 diagnosis based on a structured interview; this was replaced by a PHQ-9 depression score in a secondary analysis.

RESULTS

In the primary analysis, there were positive associations between antidepressant use and white race, younger age, unemployment, non-ischemic HF, number of other prescribed medications, current minor depression, history of major depression, and functional impairment. In the secondary analysis, there were positive associations with white race, unemployment, number of other prescribed medications, and functional impairment; the effect of current severity of depression differed between patients with vs. without a history of major depression.

CONCLUSIONS

Current depression is only one of several factors that influence the use of antidepressant medications in patients with HF. Further research is needed to ensure that these agents are being used appropriately in this patient population.

Acute heart failure

Acute heart failure (AHF) is a syndrome defined as the new onset (de novo heart failure (HF)) or worsening (acutely decompensated heart failure (ADHF)) of symptoms and signs of HF, mostly related to systemic congestion. In the presence of an underlying structural or functional cardiac dysfunction (whether chronic in ADHF or undiagnosed in de novo HF), one or more precipitating factors can induce AHF, although sometimes de novo HF can result directly from the onset of a new cardiac dysfunction, most frequently an acute coronary syndrome. Despite leading to similar clinical presentations, the underlying cardiac disease and precipitating factors may vary greatly and, therefore, the pathophysiology of AHF is highly heterogeneous. Left ventricular diastolic or systolic dysfunction results in increased preload and afterload, which in turn lead to pulmonary congestion. Fluid retention and redistribution result in systemic congestion, eventually causing organ dysfunction due to hypoperfusion. Current treatment of AHF is mostly symptomatic, centred on decongestive drugs, at best tailored according to the initial haemodynamic status with little regard to the underlying pathophysiological particularities. As a consequence, AHF is still associated with high mortality and hospital readmission rates. There is an unmet need for increased individualization of in-hospital management, including treatments targeting the causative factors, and continuation of treatment after hospital discharge to improve long-term outcomes.

Risk of aortic dissection, congestive heart failure, pneumonia and acute respiratory distress syndrome in patients with clinical vertebral fracture: a nationwide population-based cohort study in Taiwan

OBJECTIVE

Studies on the association between clinical vertebral fractures (CVFs) and the subsequent risk of cardiopulmonary diseases, including aortic dissection (AD), congestive heart failure (CHF), pneumonia and acute respiratory distress syndrome (ARDS) are scarce. Therefore, we used the National Health Insurance Research Database to investigate whether patients with CVF have a heightened risk of subsequent AD, CHF, pneumonia and ARDS.

DESIGN

The National Health Insurance Research Database was used to investigate whether patients with CVFs have an increased risk of subsequent AD, CHF, pneumonia and ARDS.

PARTICIPANTS

This cohort study comprised patients aged ≥18 years with a diagnosis of CVF and were hospitalised at any point during 2000-2010 (n=1 08 935). Each CVF patient was frequency-matched to a no-CVF hospitalised patients based on age, sex, index year and comorbidities (n=1 08 935). The Cox proportional hazard regressions model was used to estimate the adjusted effect of CVF on AD, CHF, pneumonia and ARDS risk.

RESULTS

The overall incidence of AD, CHF, pneumonia and ARDS was higher in the CVF group than in the no-CVF group (4.85 vs 3.99, 119.1 vs 89.6, 283.3 vs 183.5 and 9.18 vs 4.18/10 000 person-years, respectively). After adjustment for age, sex, comorbidities and Charlson comorbidity index score, patients with CVF had a 1.23-fold higher risk of AD (95% CI=1.03-1.45), 1.35-fold higher risk of CHF (95% CI=1.30-1.40), 1.57-fold higher risk of pneumonia (95% CI=1.54-1.61) and 2.21-fold higher risk of ARDS (95% CI=1.91-2.57) than did those without CVF. Patients with cervical CVF and SCI were more likely to develop pneumonia and ARDS.

CONCLUSIONS

Our study demonstrates that CVFs are associated with an increased risk of subsequent cardiopulmonary diseases. Future investigations are encouraged to delineate the mechanisms underlying this association.

10-Year trend in the prevalence and predictors of depression among patients with heart failure in the USA from 2007-2016

BACKGROUND

Heart failure (HF) constitutes a major public health problem in the USA with self-management playing a key role in treatment. Depressed patients often have poor insights which correlates with increased rates of adverse events such as emergency room visits, admissions and readmissions, length of hospital stay and mortality.

AIM

To determine the prevalence, trends, and predictors of depression among community-based patients with HF in the USA, and its association with self-perceived health status.

METHODS

Using the 2007 through 2016 NHANES data, we identified patients with HF aged 20-80 years with completed PHQ-9 depression screening questionnaire. PHQ-9 scores ≥10 were considered diagnostic for depression. The Chi square test was used for comparison of prevalence of depression between subgroups with p < 0.05 considered statistically significant.

RESULTS

The prevalence of depression among community-based patients with HF was 17.3% and remained stable from 2007 through 2016. Female participants, persons <60years, individuals with low socioeconomic status, and never married individuals were more likely to be depressed, comparatively. After controlling for confounders, living in poverty was the lone predictor of depression with OR 5.1 (95% CI 1.4-17.9), compared to those with incomes ≥3 times the poverty threshold. Depressed individuals were more likely to report a poor health status (76.4%) compared to non-depressed individuals (45.9%), p < 0.001.

CONCLUSION

Over 1 in 6 community-based patients with HF suffers from depression with women, individuals <60years, never married, and persons with low socioeconomic status shouldering a disproportionately higher burden.

Patients with heart failure with and without a history of stroke in the Netherlands: a secondary analysis of psychosocial, behavioural and clinical outcomes up to three years from the COACH trial

OBJECTIVE

To identify differences in psychosocial, behavioural and clinical outcomes between patients with heart failure (HF) with and without stroke.

DESIGN AND PARTICIPANTS

A secondary analysis of 1023 patients with heart failure enrolled in the Coordinating study evaluating Outcomes of Advising and Counselling in Heart failure.

SETTING

Seventeen hospitals located across the Netherlands.

OUTCOMES MEASURES

Depressive symptoms (Centre for Epidemiological Studies Depression Scale), quality of life (Minnesota Living with Heart Failure Questionnaire, Ladder of Life Scale), self-care (European Heart Failure Self-Care Behaviour Scale), adherence to HF management (modified version of the Heart Failure Compliance Questionnaire) and readmission for HF, cardiovascular-cause and all-cause hospitalisations at 18 months, and all-cause mortality at 18 months and 3 years.

RESULTS

Compared with those without stroke, patients with HF with a stroke (10.3%; n=105) had twice the likelihood of severe depressive symptoms (OR 2.83, 95% CI 1.27 to 6.28, p=0.011; OR 2.24, 95% CI 1.03 to 4.88, p=0.043) at 12 and 18 months, poorer disease-specific and generic quality of life (OR 2.80, 95% CI 1.61 to 4.84, p<0.001; OR 2.00, 95% CI 1.09 to 3.50, p=0.019) at 12 months, poorer self-care (OR 1.80, 95% CI 1.05 to 3.11, p=0.034; OR 2.87, 95% CI 1.61 to 5.11, p<0.0011) and HF management adherence (OR 0.39, 95% CI 0.18 to 0.81, p=0.012; OR 0.35, 95% CI 0.17 to 0.72, p=0.004) at 12 and 18 months, higher rates of hospitalisations and mortality at 18 months and higher all-cause mortality (HR 1.43, 95% CI 1.07 to 1.91, p=0.016) at 3 years.

CONCLUSIONS

Patients with HF and stroke have worse psychosocial, behavioural and clinical outcomes, notably from 12 months, than those without stroke. To ameliorate these poor outcomes long-term, integrated disease management pathways are warranted.

Ambulatory Advanced Heart Failure in Women: A Report From the REVIVAL Registry

OBJECTIVES

This study sought to explore clinical characteristics and outcomes in women and men with ambulatory advanced heart failure (HF).

BACKGROUND

Women have been underrepresented in studies of advanced HF and have an increased mortality on the transplant waiting list and early after mechanical circulatory support (MCS). An increased understanding of the differential burden of HF between women and men is required to inform the use of mechanical circulatory support in ambulatory advanced HF patients.

METHODS

REVIVAL (Registry Evaluation for Vital Information on Ventricular Assist Devices in Ambulatory Life) is a prospective, observational study of 400 outpatients with chronic systolic HF, New York Heart Association functional class II to IV, and 1 additional high-risk feature. Clinical characteristics, quality of life, and functional capacity were compared between women and men, as was a primary composite endpoint of death, durable MCS, or urgent heart transplantation at 1 year.

RESULTS

REVIVAL enrolled 99 women (25% of the cohort) who had similar age, ejection fraction, INTERMACS (Interagency Registry for Mechanically Assisted Circulatory Support) profiles, medication use, and willingness to consider MCS as the men enrolled; however, women reported significantly greater limitations in quality of life with respect to physical limitation, reduced 6-min walk distance, and more frequent symptoms of depression. Nevertheless, 1-year combined risk of death, durable MCS, or urgent transplantation did not differ between women and men (24% vs. 22%; p = 0.94).

CONCLUSIONS

This study represents the largest report to date of women with ambulatory advanced HF receiving contemporary therapies. Systematic elicitation of patient-reported outcome measures uncovered an added burden of HF in women and may be an appropriate target of augmented support and intervention.

Psychosocial Stress and Cardiovascular Disease

PURPOSE OF REVIEW

This manuscript reviews the epidemiological data linking psychosocial stress to cardiovascular disease (CVD), describes recent advances in understanding the biological pathway between them, discusses potential therapies against stress-related CVD, and identifies future research directions.

RECENT FINDINGS

Metabolic activity of the amygdala (a neural center that is critically involved in the response to stress) can be measured on ¹⁸F-fluorodeoxyglucose positron emission tomography/computed tomography (¹⁸F-FDG-PET/CT) yielding a neurobiological signal that independently predicts subsequent CVD events. Furthermore, a serial pathway from ↑amygdalar activity → ↑hematopoietic tissue activity → ↑arterial inflammation → ↑CVD events has been elucidated, providing new insights into the mechanism linking stress to CVD. Psychosocial stress and stress conditions are independently associated with CVD in a manner that depends on the degree and duration of stress as well as the individual response to a stressor. Nevertheless, the fundamental biology remains incompletely defined, and stress is often confounded by adverse health behaviors. Thus, most clinical guidelines do not yet recognize psychosocial stress as an independent CVD risk factor or advocate for its treatment in CVD prevention. Clarification of this neurobiological pathway provides a better understanding of the underlying pathophysiology and suggests opportunities to develop novel preventive strategies and therapies.

Anxiety, depression and quality of life in acute high risk cardiac disease patients eligible for wearable cardioverter defibrillator: Results from the prospective multicenter CRED-registry

BACKGROUND

Psychological distress is common in patients with cardiovascular disease and negatively impacts outcome.

HYPOTHESIS

Psychological distress is high in acute high risk cardiac patients eligible for a WCD, and associated with low quality of life. Distress is aggravated by WCD.

METHODS

Consecutive patients eligible for a WCD were included in the prospective, multicenter "Cologne Registry of External Defibrillator" registry. Quality of life (Short Form-12), depressive symptoms (Beck-Depression Inventory II) and anxiety (State Trait Anxiety Inventory) were assessed at enrollment and 6-weeks, and associations with WCD prescription were analyzed.

RESULTS

123 patients (mean [SD] age 59 [± 14] years, 75% male) were included, 85 (69%) of whom received a WCD. At enrollment 21% showed clinically significant depressive symptoms and 52% anxiety symptoms, respectively. At 6 weeks, depressive and anxious symptoms significantly decreased to 7% and 25%, respectively. Depressive symptoms at enrollment and changes at 6 weeks showed significant associations with health-related quality of life, whereas anxious symptoms did not. There was a trend for better improvement of depression scores in patients with WCD (mean [SD] change in score points: -4.1 [6.1] vs -1.8 [3.9]; p = 0.09), whereas change of the anxiousness score was not different (-4.6 [9.5]) vs -3.7 [9.1], p = 0.68).

CONCLUSION

In patients eligible for a WCD, depressive and anxiety symptoms were initially common and depressive symptoms showed a strong association with reduced health-related quality of life contributing to their clinical relevance. WCD recipients showed at least similar improvement of depression and anxiety at 6 weeks when compared to non recipients.

Associations of mood symptoms with NYHA functional classes in angina pectoris patients: a cross-sectional study

BACKGROUND

Depression and anxiety are prevalent and associated with a worse prognosis in coronary heart disease (CHD) patients. However, the influence of disease severity on mood symptoms is unknown. The specific associations of mood symptoms with NYHA classes remain unexplored.

METHODS

In this cross-sectional study, 443 consecutive inpatients with angina pectoris (AP) confirmed by angiography were included into analysis. Somatic and cognitive symptom scores derived from Patient Health Questionnaire (PHQ-9) and Generalized Anxiety Disorder Scale (GAD-7) were used to assess mood symptoms. Predictors for depression and anxiety with strict and lax standards were compared. We hypothesized NYHA classification to be an indicator of disease severity through analyses with clinical features using ordinal logistic model. Applying both binary and ordinal logistic models, we evaluated the associations of mood symptoms with NYHA classes.

RESULTS

Discrepancy of disease severity existed between the depressed and nondepressed. NYHA classification was proved to be an integrated index under influence of age, coronary stenosis, heart failure and diabetes. NYHA class I and II individuals with AP were at equivalent risk for depression (NYHA II vs I: binary model OR 1.32 (0.59,2.96), p = 0.50; ordinal model OR 1.17 (0.73,1.88), p = 0.52), however NYHA class III/IV patients shared a sharply higher risk (NYHA III/IV vs I: binary model OR 3.32 (1.28,8.61), p = .013; ordinal model OR 3.94 (2.11,7.36), p < .001). Analyses on somatic and cognitive depressive symptoms confirmed this finding and hinted a greater impact of education background on mood when patient's condition is unstable. Anxiety seemed in the whole picture irrelevant with NYHA classes. Comparing with NYHA class I/II, AP patients in NYHA class III/IV tended to be less anxious. However, when CHD became unstable, the calmness may immediately be broken up. A great distinction of the ratio of anxiety and depression symptom scores between NYHA class III/IV stable and unstable AP patients (p = .018) was observed.

CONCLUSIONS

Mood symptoms in CHD patients are to a great extend derived from disease itself. Only for patients with relatively serious physical condition, unexpected discomforts caused by disease notably impact the emotions. Education background tends to influence the mood especially when disease is still unstable.

Frequency and predictors of depression in congestive heart failure

Background

Depression in congestive heart failure (CHF) patients can increase morbidity and mortality. Given the ever-rising prevalence of CHF patients with depression, it is vital that we understand the predictors of depression in these patients to identify and better manage these patients. The main objective of this study was to evaluate the frequency and predictors of depression in CHF patients.

Methods

A cross-sectional study was conducted in a tertiary care hospital. Patients with a diagnosis of CHF for more than 6 months based on signs and left ventricular ejection fraction <40% were included. Patients were interviewed with the Patient Health Questionnaire-9 (PHQ-9) consisting of nine items in line with the Diagnostic and Statistical Manual (DSM) - IV criteria to assess depression. Each item was scored from 0 to 3, and a PHQ-9 score of 10 or greater suggested clinical depression. Data were analyzed on SPSS, v22, and a p < 0.05 was considered significant.

Results

Of 170 participants, 102 (60%) had depression. Among these 102 patients, 42% (n = 43) had mild depression, and the rest (n = 59) had moderate-to-severe depression. Predictors of depression were New York Heart Association stage 3 or 4 (p = 0.001), previous myocardial infarction (p = 0.001), living without a partner (p = 0.001), lack of a joint family system (p = 0.001), sedentary lifestyle (p = 0.001), aged 70 years or more (p = 0.01), and having been admitted in a hospital at least once in the past two months (p = 0.002).

Conclusion

Depression is common among patients with CHF. It is associated with multiple factors and needs to be addressed and targeted urgently.

Comorbidities and Consequences in Hospitalized Heart Failure Patients with Depression

Objective

To evaluate the demographic predictors of major depressive disorder (MDD) in hospitalized congestive heart failure (CHF) patients and measure the differences in hospital stay and cost per comorbidities and the associated risk of in-hospital mortality.

Methods

This retrospective cross-sectional study used nationwide inpatient data from the healthcare cost and utilization project (HCUP). We identified patients with CHF as the primary diagnosis and MDD as the secondary diagnosis using ICD-9-CM codes and compared with the CHF patient without MDD. The differences in comorbidities were quantified using chi-square tests and the logistic regression model was used to evaluate mortality risk among comorbidities using odds ratio (OR).

Results

Elder CHF patients, 36–50-year-old (OR: 1.324) and whites (OR: 1.673), have a higher likelihood of a co-diagnosis of MDD. Females with heart failure have two-fold higher odds of MDD (OR: 2.332). Majority of the medical comorbidities were seen in a higher proportion of CHF patients without MDD. Hypothyroidism (10.2%) and drug abuse (15.2%) were seen more in depressed patients comparatively. Among substance use disorder, patients with drug abuse stayed longer and had a higher hospitalization total cost ($51,828). And, hypothyroidism was associated with longer inpatient stay (5.6 days) and cost ($64,726), and four-fold higher odds of in-hospital mortality (OR: 4.405). Though alcohol abuse was seen only in 7.4% of CHF patients with MDD, it was associated with the three-fold higher likelihood of deaths during hospitalization (OR: 3.195).

Conclusion

A middle-aged, white female with comorbid depression has a higher risk of hospitalization for heart failure. Depressed CHF patients with comorbid hypothyroidism were hospitalized for a longer duration with higher inpatient cost and four times higher risk of mortality during hospitalization stay. Further studies are required to evaluate the underlying cause of worse hospital outcomes in depressed CHF patients with alcohol abuse and hypothyroidism. An integrated healthcare model is required for early diagnosis and treatment of depression and associated comorbidities in CHF patients to reduce mortality and improve post-CHF outcomes.

Is Heart Failure Associated With Risk of Suicide?

BACKGROUND

The high prevalence of heart failure (HF) in developed countries imposes a substantial burden on health care resources. Depression is widely recognized as a risk factor associated with HF. This study examined the relationship between suicide and HF after controlling for depression and other comorbidities.

METHODS AND RESULTS

The population comprised 52,749 adult patients who died from suicide from 2000 to 2012 and 210,996 living control subjects matched by age, sex, and residence area. Data were obtained from the Health and Welfare Data Science Center, Taiwan. Multivariable models were constructed to evaluate the relationship between HF and suicide. In the case and control groups 1624 (3.08%) and 4053 (1.92%) patients had HF, respectively, indicating that HF was associated with an increased risk of suicide (odds ratio [OR] 1.68, 95% confidence interval [CI] 1.59-1.79). The risk of suicide was highest during the initial 6 months after HF (adjusted OR 7.04, 95% CI 5.37-9.22) and subsequently declined gradually. Among psychiatric disorders, mood disorders (adjusted OR 7.42, 95% CI 7.06-7.79) yielded the highest odds of suicide.

CONCLUSIONS

The risk of suicide is higher for patients with HF than for healthy individuals without HF. This risk is particularly high during the first 6 months after HF diagnosis. This study provides strong evidence that depression is a negative prognostic factor for patients with HF and increases the risk of suicide. The results suggest that early screening and treatment for depression and suicide risk should be conducted for patients with HF.

Stress and the psyche-brain-immune network in psychiatric diseases based on psychoneuroendocrineimmunology: a concise review

In the last decades, psychoneuroendocrineimmunology research has made relevant contributions to the fields of neuroscience, psychobiology, epigenetics, molecular biology, and clinical research by studying the effect of stress on human health and highlighting the close interrelations between psyche, brain, and bodily systems. It is now well recognized that chronic stress can alter the physiological cross-talk between brain and biological systems, leading to long-lasting maladaptive effects (allostatic overload) on the nervous, immune, endocrine, and metabolic systems, which compromises stress resiliency and health. Stressful conditions in early life have been associated with profound alterations in cortical and subcortical brain regions involved in emotion regulation and the salience network, showing relevant overlap with different psychiatric conditions. This paper provides a summary of the available literature concerning the notable effects of stress on the brain and immune system. We highlight the role of epigenetics as a mechanistic pathway mediating the influences of the social and physical environment on brain structure and connectivity, the immune system, and psycho-physical health in psychiatric diseases. We also summarize the evidence regarding the effects of stress management techniques (mainly psychotherapy and meditation practice) on clinical outcomes, brain neurocircuitry, and immune-inflammatory network in major psychiatric diseases.

Is Exercise Training Appropriate for Patients With Advanced Heart Failure Receiving Continuous Inotropic Infusion? A Review

Exercise-based rehabilitation programs have been reported to have beneficial effects for patients with heart failure. However, there is little evidence about whether this is the case in patients with more severe heart failure. In particular, there is a question in the clinical setting whether patients with advanced heart failure and continuous inotropic infusion should be prescribed exercise training. In contrast, many studies conclude that prolonged immobility associated with heart failure profoundly impairs physical function and promotes muscle wasting that could further hasten the course of heart failure. By contrast, exercise training has various effects not only in improving exercise capacity but also on vascular function, skeletal muscle, and autonomic balance. In this review, we summarize the effectiveness and discuss methods of exercise training in patients with advanced heart failure receiving continuous inotropic agents such as dobutamine.

Expert Opinion-Depression in Patients with Heart Failure: Is Enough Being Done?

Depression is a major issue in heart failure (HF). Depression is present in about one in five HF patients, with about 48 % of these individuals having significant depression. There is a wide variation in reported prevalences because of differences in the cohorts studied and methodologies. There are shared pathophysiological mechanisms between HF and depression. The adverse effects of depression on the outcomes in HF include reduced quality of life, reduced healthcare use, rehospitalisation and increased mortality. Results from metaanalysis suggest a twofold increase in mortality in HF patients with compared to those without depression. Pharmacological management of depression in HF has not been shown to improve major outcomes. No demonstrable benefits over cognitive behavioural therapy and psychotherapy have been demonstrated.
