Effects of a stress management program on vital exhaustion and depression in women with coronary heart disease: a randomized controlled intervention study

Psychological interventions targeting mental health and stress among females with cardiac disease: a scoping review

Interventions that target mental health symptoms and stress among those with established cardiac disease have included predominately male samples despite female patients reporting greater severity of these symptoms. The aim of this scoping review was to synthesize the published literature on psychological interventions for females with cardiac disease. We conducted a systematic search of peer-reviewed randomized clinical trials (RCTs) published in the English language from 2003 to 2023, in three databases: Medline (Ovid), PsycInfo (Ovid), and CINAHL (EBSCO). Articles that included female samples, a control or comparison group, implemented psychological interventions, and measured depression, anxiety, or stress as an outcome were included in the review. Nine articles describing eight RCTs of psychological interventions, with a total of 1587 female patients with cardiac disease, were included. Interventions were most successful at reducing stress (75% of studies measuring stress reported efficacy), while symptoms of depression and anxiety were less responsive to intervention (∼30% of studies targeting these symptoms reported improvements) in comparison to a control condition. This scoping review highlights that further advancement in knowledge is required to better address the needs of females with cardiac disease and distress, particularly depression and anxiety.

Psychological profiles of individuals with type 2 diabetes and their association with physical and psychological outcomes: a cluster analysis

OBJECTIVES

This study aimed to identify clusters of participants with Type 2 diabetes mellitus (T2DM) at risk for developing psychological and somatic distress symptoms. Moreover, we investigated whether the different clusters were associated with glycemic control, sleep, and physical activity levels.Design and main outcome measures. In a cross-sectional design, participants with T2DM (n = 269) completed questionnaires on psychological and somatic distress, sleep disorders and physical activity.

RESULTS

Cluster analyses yielded three groups: a) "high self-confident and low demoralised"; b) "low support and low involvement"; c) "high consequences, high demoralisation and nagging". The groups were distinguished by the social, cognitive, and vital exhaustion variables and significant differences in diabetes-related psychological distress and physical activity. The measure of glycemic control did not differ between clusters. The "high self-confident and low demoralised" group displayed the lowest scores on psychological distress compared to the other clusters.

CONCLUSIONS

Results suggest that social cognitive dimensions and affective states play a key role in defining clusters in participants with T2DM. Thus, we need to consider the psychological profiles of participants with T2DM when designing interventions to improve self-management strategies.

Effectiveness of cognitive behavioral therapy-based interventions on health outcomes in patients with coronary heart disease: A meta-analysis

BACKGROUND

Recently, the efficacy of cognitive behavioral therapy (CBT)-based intervention on health outcomes in patients with coronary heart disease (CHD) has been recognized in randomized controlled trials (RCTs), but no comprehensive systematic review has been conducted. To address this research gap, our study aimed to evaluate whether comprehensive CBT-based interventions positively affect health outcomes in CHD patients. It was hypothesized that CBT-based interventions are effective in: (1) Reducing depression, anxiety, and stress symptoms; (2) Reducing body mass index, blood pressure, and lipid levels; and (3) Improving quality of life, and exercise endurance.

AIM

To verify the effectiveness of CBT-based interventions on CHD patients through a meta-analysis of previous publications.

METHODS

Relevant RCTs published in English were obtained by searching electronic databases, including PubMed, Embase, Cochrane Central Register of Controlled Trials, Scopus, and Proquest, with the retrieval time from inception to August 2020. The primary outcomes were psychological factors (depression, anxiety, and stress symptoms), physiological factors (body mass index, blood pressure, blood lipids). The secondary outcomes included quality of life and exercise endurance. We used Review Manager 5.3 to conduct the meta-analysis and used the Physiotherapy Evidence Database tool to evaluate the quality of studies.

RESULTS

A total of 22 RCTs comprising 4991 patients with CHD were included in the systematic review and meta-analysis. The main analysis revealed that CBT-based intervention can reduce depression symptoms: -2.00 [95% confidence interval (CI): -2.83 to -1.16, P < 0.001]; anxiety symptoms: -2.07 (95%CI: -3.39 to -0.75, P = 0.002); stress symptoms: -3.33 (95%CI: -4.23 to -2.44, P < 0.001); body mass index: -0.47 (95%CI: -0.81 to -0.13, P = 0.006); and improve physical functioning: 3.36 (95%CI: 1.63 to 5.10, P = 0.000) and mental functioning: 6.91 (95%CI: 4.10 to 9.73, P < 0.001). Moreover, subgroup analysis results showed that CBT-based interventions were more effective for symptoms of depression and anxiety in CHD patients when individual, as opposed to group treatment, and psycho-education, behavioral and cognitive strategies were applied as the core treatment approaches.

CONCLUSION

CBT-based interventions are effective treatment strategies for CHD patients, significantly improving their symptoms of depression, anxiety and stress, body mass index, and health-related quality of life.

Effects of psychosocial support interventions on survival in inpatient and outpatient healthcare settings: A meta-analysis of 106 randomized controlled trials

BACKGROUND

Hospitals, clinics, and health organizations have provided psychosocial support interventions for medical patients to supplement curative care. Prior reviews of interventions augmenting psychosocial support in medical settings have reported mixed outcomes. This meta-analysis addresses the questions of how effective are psychosocial support interventions in improving patient survival and which potential moderating features are associated with greater effectiveness.

METHODS AND FINDINGS

We evaluated randomized controlled trials (RCTs) of psychosocial support interventions in inpatient and outpatient healthcare settings reporting survival data, including studies reporting disease-related or all-cause mortality. Literature searches included studies reported January 1980 through October 2020 accessed from Embase, Medline, Cochrane Library, CINAHL, Alt HealthWatch, PsycINFO, Social Work Abstracts, and Google Scholar databases. At least 2 reviewers screened studies, extracted data, and assessed study quality, with at least 2 independent reviewers also extracting data and assessing study quality. Odds ratio (OR) and hazard ratio (HR) data were analyzed separately using random effects weighted models. Of 42,054 studies searched, 106 RCTs including 40,280 patients met inclusion criteria. Patient average age was 57.2 years, with 52% females and 48% males; 42% had cardiovascular disease (CVD), 36% had cancer, and 22% had other conditions. Across 87 RCTs reporting data for discrete time periods, the average was OR = 1.20 (95% CI = 1.09 to 1.31, p < 0.001), indicating a 20% increased likelihood of survival among patients receiving psychosocial support compared to control groups receiving standard medical care. Among those studies, psychosocial interventions explicitly promoting health behaviors yielded improved likelihood of survival, whereas interventions without that primary focus did not. Across 22 RCTs reporting survival time, the average was HR = 1.29 (95% CI = 1.12 to 1.49, p < 0.001), indicating a 29% increased probability of survival over time among intervention recipients compared to controls. Among those studies, meta-regressions identified 3 moderating variables: control group type, patient disease severity, and risk of research bias. Studies in which control groups received health information/classes in addition to treatment as usual (TAU) averaged weaker effects than those in which control groups received only TAU. Studies with patients having relatively greater disease severity tended to yield smaller gains in survival time relative to control groups. In one of 3 analyses, studies with higher risk of research bias tended to report better outcomes. The main limitation of the data is that interventions very rarely blinded personnel and participants to study arm, such that expectations for improvement were not controlled.

CONCLUSIONS

In this meta-analysis, OR data indicated that psychosocial behavioral support interventions promoting patient motivation/coping to engage in health behaviors improved patient survival, but interventions focusing primarily on patients' social or emotional outcomes did not prolong life. HR data indicated that psychosocial interventions, predominantly focused on social or emotional outcomes, improved survival but yielded similar effects to health information/classes and were less effective among patients with apparently greater disease severity. Risk of research bias remains a plausible threat to data interpretation.

Psychiatric and Psychosomatic Consultation-Liaison Services in General Hospitals: A Systematic Review and Meta-Analysis of Effects on Symptoms of Depression and Anxiety

BACKGROUND

Psychiatric and psychosomatic consultation-liaison services (CL) are important providers of diagnosis and treatment for hospital patients with mental comorbidities and psychological burdens.

OBJECTIVE

To perform a systematic review and meta-analysis investigating the effects of CL on depression and anxiety.

METHODS

Following PRISMA guidelines, a systematic literature search was conducted until 2017. Included were published randomized controlled trials using CL interventions with adults in general hospitals, treatment as usual as control groups, and depression and/or anxiety as outcomes. Risk of bias was assessed using the Cochrane Risk of Bias Tool. Level of integration was assessed using the Standard Framework for Levels of Integrated Healthcare. Meta-analyses were performed using random effects models and meta-regression for moderator effects.

RESULTS

We included 38 studies (9,994 patients). Risk of bias was high in 17, unclear in 15, and low in 6 studies. Studies were grouped by type of intervention: brief interventions tailored to the patients (8), interventions based on specific treatment manuals (19), and integrated, collaborative care (11). Studies showed small to medium effects on depression and anxiety. Meta-analyses for depression yielded a small effect (d = -0.19, 95% CI: -0.30 to -0.09) in manual studies and a small effect (d = -0.33, 95% CI: -0.53 to -0.13) in integrated, collaborative care studies, the latter using mostly active control groups with the possibility of traditional consultation.

CONCLUSIONS

CL can provide a helpful first treatment for symptoms of depression and anxiety. Given that especially depressive symptoms in medically ill patients are long-lasting, the results underline the benefit of integrative approaches that respect the complexity of the illness.

Stress Management and Resilience Intervention in a Women's Heart Clinic: A Pilot Study

Background: In general, women report higher stress levels than men. High baseline anxiety, depression, and stress levels are associated with greater risk of cardiovascular diseases. Current evidence for efficacy of stress management interventions for women is limited. This study aimed at assessing the effect of a stress management and resiliency training (SMART) program for decreasing stress, anxiety, and depressive symptoms. Methods: Fifty moderately or severely stressed Women's Heart/Preventive Cardiology Clinic patients consented to the SMART intervention delivered online (n = 36) or in-person (n = 9). Primary outcome measures were the observed changes between baseline and at 12 weeks for the following psychometric tools: General Anxiety Disorder-7 (GAD-7), Patient Health Questionnaires (PHQ-9), Perceived Stress Scale (PSS), and Brief Resiliency Scale (BRS). Results: Forty-five patients completed the study. We observed significant improvements in PSS and GAD-7, but not in PHQ-9 or BRS, after the SMART intervention. When assessing outcomes among those with depressive symptoms at baseline (PHQ-9 > 15), we observed significant changes in PSS, GAD-7, and PHQ-9. No differences between online and in-person program delivery methods were found (all p-values >0.05). Conclusions: Training exposure using the SMART program to decrease stress and anxiety in women seeking preventive cardiology services was feasible and similarly effective, whether delivered online or in a single in-person session. Impacts on depression and resilience likely require a more intensive approach. In the future, larger randomized clinical trials with additional training and longer follow-up are warranted.

Decline of substance P levels after stress management with cognitive behaviour therapy in women with the fibromyalgia syndrome

Background and aims

Substance P (CSF-SP) is known to be elevated in females with fibromyalgia syndrome (FMS). The aims of this study were to evaluate the effect of cognitive behaviour therapy (CBT) on plasma SP levels in women with FMS and to find possible clinical behavioural correlates to plasma SP level changes.

Methods

Forty-eight women with FMS were randomly allocated into two groups. Group 1 received the CBT treatment intervention over the course of 6 months while group 2 was waitlisted. CBT was given with a protocol developed to diminish stress and pain. After 6 months, group 2 was given the same CBT treatment as well. All were followed up 1 year after the start of CBT treatment. This approach allowed for two analytical designs – a randomised controlled trial (RCT) (n=24 vs. n=24) and a before-and-after treatment design (n=48). All women were repeatedly evaluated by the West Haven-Yale Multidimensional Pain Inventory (MPI) and three other psychometric questionnaires and plasma SP was analysed.

Results

In the RCT design, the plasma SP level was 8.79 fmol/mL in both groups at the start of the trial, after adjustment for initial differences. At the end of the RCT, the plasma SP level was 5.25 fmol/mL in the CBT intervention group compared to 8.39 fmol/mL in the control group (p=0.02). In the before-and-after design, the plasma SP was reduced by 33% (p<0.01) after CBT, but returned to the pre-treatment level at follow-up 1 year after the start of CBT treatment. Plasma SP was associated with the MPI dimensions experienced “support from spouses or significant others” and “life control”.

Conclusions

Plasma SP might be a marker of the effect of CBT in FMS associated with better coping strategies and reduced stress rather than a biochemical marker of pain.

Qualitative Analysis of Emotional Distress in Cardiac Patients From the Perspectives of Cognitive Behavioral and Metacognitive Theories: Why Might Cognitive Behavioral Therapy Have Limited Benefit, and Might Metacognitive Therapy Be More Effective?

Introduction: Cognitive behavioral therapy (CBT) alleviates emotional distress in mental health settings, but has only modest effects in cardiac patients. Metacognitive therapy (MCT) also alleviates depression and anxiety in mental health settings and is in its initial stages of evaluation for cardiac patients. Aim: Our objective is to compare how CBT and MCT models conceptualize cardiac patients' distress, and to explore why CBT has had limited benefit for cardiac patients and whether MCT has the potential to be more efficacious. Method: Forty-nine cardiac rehabilitation patients, who screened positively for anxiety and/or depression, provided semi-structured interviews. We analyzed transcripts qualitatively to explore the "fit" of patients' accounts of their distress with the main elements of cognitive behavioral and metacognitive theories. Four illustrative cases, representative of the diverse presentations in the broader sample, were analyzed in detail and are presented here. Results: Conceptualizing patients' distress from the perspective of CBT involved applying many distinct categories to describe specific details of patients' talk, particularly the diversity of their concerns and the multiple types of cognitive distortion. It also required distinction between realistic and unrealistic thoughts, which was difficult when thoughts were associated with the risk or consequences of cardiac events. From the perspective of MCT a single category-perseverative negative thinking-was sufficient to understand all this talk, regardless of whether it indicated realistic or unrealistic thoughts, and could also be applied to some talk that did not seem relevant from a CBT perspective. Discussion: Conceptualizing distress from the perspective of CBT presents multiple, diverse therapeutic targets, not all of which a time-limited therapy would be able to address. Given the difficulty of identifying them as unrealistic or not, thoughts about disease, death or disability may not be amenable to classic CBT techniques such as reality testing. MCT proved more parsimonious and, because it did not distinguish between realistic and unrealistic thoughts, might prove a better fit to emotional distress in cardiac patients.

Comparative Effectiveness of the Core Components of Cardiac Rehabilitation on Mortality and Morbidity: A Systematic Review and Network Meta-Analysis

A systematic review and network meta-analysis (NMA) of randomized controlled trials (RCTs) evaluating the core components of cardiac rehabilitation (CR), nutritional counseling (NC), risk factor modification (RFM), psychosocial management (PM), patient education (PE), and exercise training (ET)) was undertaken. Published RCTs were identified from database inception dates to April 2017, and risk of bias assessed using Cochrane's tool. Endpoints included mortality (all-cause and cardiovascular (CV)) and morbidity (fatal and non-fatal myocardial infarction (MI), coronary artery bypass surgery (CABG), percutaneous coronary intervention (PCI), and hospitalization (all-cause and CV)). Meta-regression models decomposed treatment effects into the main effects of core components, and two-way or all-way interactions between them. Ultimately, 148 RCTs (50,965 participants) were included. Main effects models were best fitting for mortality (e.g., for all-cause, specifically PM (hazard ratio HR = 0.68, 95% credible interval CrI = 0.54⁻0.85) and ET (HR = 0.75, 95% CrI = 0.60⁻0.92) components effective), MI (e.g., for all-cause, specifically PM (hazard ratio HR = 0.76, 95% credible interval CrI = 0.57⁻0.99), ET (HR = 0.75, 95% CrI = 0.56⁻0.99) and PE (HR = 0.68, 95% CrI = 0.47⁻0.99) components effective) and hospitalization (e.g., all-cause, PM (HR = 0.76, 95% CrI = 0.58⁻0.96) effective). For revascularization (including CABG and PCI individually), the full interaction model was best-fitting. Given that each component, individual or in combination, was associated with mortality and/or morbidity, recommendations for comprehensive CR are warranted.

Role of Stress and Psychosocial Determinants on Women's Cardiovascular Risk and Disease Development

The notion that cardiovascular disease (CVD) primarily occurs in men is slowly disappearing. More women than men die of CVD every year, and when women survive, the burden and consequences are worse than in men. Markers of stress and other psychosocial factors have been associated with poor outcomes. Multiple studies have demonstrated sex-based differences in the vascular and endothelial responses to mental stress. Psychosocial stressors were also found to be independent risk factors for the development and progression of CVD. This review arises from accumulating evidence suggesting that psychological well-being may improve cardiac-related outcomes, independent of cardiac risk factors. Despite the fact that positive physician-patient engagement is likely to play a critical role in promoting positive psychological traits and healthy behaviors, current physician awareness and advocacy are rather suboptimal, despite active awareness campaigns such as the American Heart Association's Go Red for Women^®. There is a need to further study the role and management of stress as a CVD risk factor, especially in women, who are disproportionately affected.

Gender differences in psychosocial outcomes of psychotherapy trial in patients with depression and coronary artery disease

INTRODUCTION

The biological and psychosocial risk profile differs between women and men with coronary artery disease (CAD). Depressive symptoms and Vital Exhaustion (VE) predict an unfavourable course of CAD. The secondary analysis of the SPIRR-CAD trial offered the possibility to examine gender as exposure variable of the clinical and psychological situation at baseline and in a variety of psychosocial measures as outcomes.

METHODS

In this trial, 450 men (78.9%) and 120 women (21.1%) with CAD (age ≤ 75 y), with mild to moderate depression (scoring ≥8 on the HADS), were randomized to usual care with or without a stepwise psychotherapy intervention. Beside clinical measures exhaustion and other indicators of depressive symptoms were collected at baseline and 18-month follow up.

RESULTS

Men had more signs and symptoms of heart disease at baseline, whereas women had higher psychosocial burden (e.g. negative affect). Women were more likely to live alone, had lower educational levels and employment rates and higher levels of depression and exhaustion. The psychotherapy intervention differed as a function of gender: In women, VE decreased from 29.4 ± 8.1 to 22.1 ± 11.7 in the intervention group (IG) and from 29.2 ± 8.2 to 25.1 ± 11.3 in the control group (CG). In men VE decreased from 23.3 + -10.8 to 21.2 ± 9.7 in the IG and from 23.6 ± 10.7 to 19.3 ± 11.3 in the CG (time x intervention x gender; F = 4.97; p = .026).

DISCUSSION

Women had a higher psychosocial burden than men. VE compared to other rating instruments of depressive symptoms suggested a stronger response to the intervention in women. VE may help to understand gender differences in psychotherapeutic treatment studies of CAD.

Longitudinal associations of burnout with heart rate variability in patients following acute coronary syndrome: A one-year follow-up study

OBJECTIVE

To investigate longitudinal associations of burnout with heart rate variability (HRV) in patients after their first events of acute coronary syndrome (ACS).

METHODS

In total, two hundred eight patients participated in this one-year follow-up study. On the day before discharge, their personal burnout level was assessed by the Copenhagen Burnout Inventory. HRV signals were collected at four time points: the day before discharge, one month, six month and one year after discharge. HRV was measured by 24-hour ambulatory electrocardiography and analyzed in time and frequency domains. Generalized estimating equations were applied to analyze the associations of burnout at baseline with longitudinal tracking of HRV during follow-up in format of natural logarithmic transformation.

RESULTS

After adjusting for relevant confounding factors, high burnout at baseline was significantly associated with low standard deviation of NN intervals (SDNN), a time domain measure of HRV (p < 0.05). Also, baseline burnout was inversely associated with five frequency domain measures, i.e., high frequency power (HF), low frequency power (LF), very low frequency power (VLF), and ultra low frequency power (ULF), and total power (TP) (all p < 0.05).

CONCLUSION

Personal burnout is longitudinally associated with decreased HRV during one-year period among patients after first ACS.

Self-Management Interventions for Women With Cardiac Pain: A Systematic Review and Meta-analysis

BACKGROUND

Cardiac pain is considered the primary indicator of coronary artery disease (CAD). Existing reviews lack appropriate numbers of women or sex-based subgroup analyses, or both; thus, the benefits of self-management (women with cardiac pain actively participating in their own care and treatment) remain uncertain.

METHODS

Using methods described by the Evidence for Policy and Practice Information and Co-ordinating Centre at the Institute of Education, 7 databases were systematically searched to examine and synthesize the evidence on self-management interventions for women with cardiac pain and cardiac pain equivalents, such as fatigue, dyspnea, and exhaustion.

RESULTS

Our search yielded 22,402 article titles and abstracts. Of these, 57 randomized controlled trials were included in a final narrative synthesis, comprising data from 13,047 participants, including 5299 (41%) women. Self-management interventions targeting cardiac pain in women compared with a control population reduced (1) cardiac pain frequency and cardiac pain proportion (obstructive and nonobstructive CAD), (2) fatigue at 12 months, and (3) dyspnea at 2 months. There was no evidence of group differences in postprocedural (percutaneous coronary intervention or cardiac surgery) pain. Results indicated that self-management interventions for cardiac pain were more effective if they included a greater proportion of women (standardized mean difference [SMD], -0.01; standard error, 0.003; P = 0.02), goal setting (SMD, -0.26; 95% confidence interval [CI], -0.49 to -0.03), and collaboration/support from health care providers (SMD, -0.57; 95% CI, -1.00 to -0.14).

CONCLUSIONS

The results of this review suggest that self-management interventions reduce cardiac pain and cardiac pain equivalents.

Psychobiological stress in vital exhaustion. Findings from the Men Stress 40+ study

OBJECTIVE

Despite the increased risk for cardiovascular morbidity associated with vital exhaustion (VE), the underlying pathophysiological mechanisms remain unclear. Allostatic load may constitute the missing link between VE and cardiovascular diseases. The aim of the present study was to investigate whether men with different degrees of VE would differ in terms of allostatic load, chronic stress, and social support.

METHODS

The Men Stress 40+ study sample consisted of N=121 apparently healthy men aged 40 to 75years. The following allostatic load markers were aggregated to create a cumulative index of biological stress: salivary cortisol, salivary dehydroepiandrosterone sulfate (DHEA-S), waist-to-hip-ratio, systolic and diastolic blood pressure. Long-term cortisol and DHEA were additionally measured in hair. Chronic stress and social support were assessed via validated questionnaires. Groups of mildly, substantially, and severely exhausted men were compared using one-way ANOVAs with appropriate post-hoc tests.

RESULTS

Men who reported mild or severe levels of vital exhaustion had the highest scores on the cumulative index of biological stress. Hair cortisol was unrelated to vital exhaustion; hair DHEA was highest in men with substantial levels of exhaustion. Men with mild exhaustion reported the lowest levels of chronic stress, while men with severe exhaustion reported the lowest levels of social support.

CONCLUSIONS

Signs of allostatic load are detectable in vitally exhausted men at a stage where no major cardiovascular consequences have yet ensued.

Psychological interventions for coronary heart disease: Cochrane systematic review and meta-analysis

Background

Although psychological interventions are recommended for the management of coronary heart disease (CHD), there remains considerable uncertainty regarding their effectiveness.

Design

Systematic review and meta-analysis of randomised controlled trials (RCTs) of psychological interventions for CHD.

Methods

The Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, CINAHL and PsycINFO were searched to April 2016. Retrieved papers, systematic reviews and trial registries were hand-searched. We included RCTs with at least 6 months of follow-up, comparing the direct effects of psychological interventions to usual care for patients following myocardial infarction or revascularisation or with a diagnosis of angina pectoris or CHD defined by angiography. Two authors screened titles for inclusion, extracted data and assessed risk of bias. Studies were pooled using random effects meta-analysis and meta-regression was used to explore study-level predictors.

Results

Thirty-five studies with 10,703 participants (median follow-up 12 months) were included. Psychological interventions led to a reduction in cardiovascular mortality (rfcelative risk 0.79, 95% confidence interval [CI] 0.63 to 0.98), although no effects were observed for total mortality, myocardial infarction or revascularisation. Psychological interventions improved depressive symptoms (standardised mean difference [SMD] –0.27, 95% CI –0.39 to –0.15), anxiety (SMD –0.24, 95% CI –0.38 to –0.09) and stress (SMD –0.56, 95% CI –0.88 to –0.24) compared with controls.

Conclusions

We found that psychological intervention improved psychological symptoms and reduced cardiac mortality for people with CHD. However, there remains considerable uncertainty regarding the magnitude of these effects and the specific techniques most likely to benefit people with different presentations of CHD.

Emotions and Steroid Secretion in Aging Men: A Multi-Study Report

Although aging increases the risk of cognitive and socioemotional deterioration, it has also been shown to be accompanied by an increase in experienced positive emotions and a decrease in negative emotions. Steroid hormones and age-related alterations in secretion patterns have been suggested to play a crucial role in these age-related changes in emotional experience. Importantly, previous studies identified effects of neuroactive hormones on age-related alterations in emotional experience, which vary by sex and depression levels. Therefore, in three independent cross-sectional studies including a total of 776 men, we examined age-related differences in emotional experience and subsequently the moderation effect of steroid hormones. Sample one consisted of 271 self-reporting healthy (SRH) men aged between 40 and 75 years, while sample two comprised 121 men in the identical age range but only including vitally exhausted (VE) men. Sample three included 384 men aged between 25 and 78 years who reported having fathered (FA) at least one child. For the SRH men, age was negatively associated with anxiety symptoms and aggression, while negative trends emerged for depressive symptoms. In VE men, age was negatively associated with depressive symptoms and positively associated with aggression and positive emotions. For FA men, anxiety symptoms and aggression were negatively associated with age. Age trends of steroid hormones and identified moderation effects are reported. However, with adjustment for multiple comparisons, most of the significant associations fade and the reported associations need to be regarded as exploratory starting points for the further investigation of age-related alterations in emotional experience and their relation to steroid secretion. Overall, the results indicate that salivary cortisol might be a moderator of the association between age and symptoms of anxiety for SRH and VE men, while salivary testosterone seems to moderate the association between age and symptoms of anxiety or depression in VE and FA men, respectively. Both hair cortisol and progesterone seem to influence age-related alterations in anger experience. Age-related alterations in the hypothalamic-pituitary-adrenal (HPA) axis and the hypothalamic-pituitary-gonadal (HPG) axis emerge as promising avenues to further investigate the decrease in experienced negative emotions in aging men.

Psychological interventions for coronary heart disease

BACKGROUND

Coronary heart disease (CHD) is the most common cause of death globally, although mortality rates are falling. Psychological symptoms are prevalent for people with CHD, and many psychological treatments are offered following cardiac events or procedures with the aim of improving health and outcomes. This is an update of a Cochrane systematic review previously published in 2011.

OBJECTIVES

To assess the effectiveness of psychological interventions (alone or with cardiac rehabilitation) compared with usual care (including cardiac rehabilitation where available) for people with CHD on total mortality and cardiac mortality; cardiac morbidity; and participant-reported psychological outcomes of levels of depression, anxiety, and stress; and to explore potential study-level predictors of the effectiveness of psychological interventions in this population.

SEARCH METHODS

We updated the previous Cochrane Review searches by searching the following databases on 27 April 2016: CENTRAL in the Cochrane Library, MEDLINE (Ovid), Embase (Ovid), PsycINFO (Ovid), and CINAHL (EBSCO).

SELECTION CRITERIA

We included randomised controlled trials (RCTs) of psychological interventions compared to usual care, administered by trained staff, and delivered to adults with a specific diagnosis of CHD. We selected only studies estimating the independent effect of the psychological component, and with a minimum follow-up of six months. The study population comprised of adults after: a myocardial infarction (MI), a revascularisation procedure (coronary artery bypass graft (CABG) or percutaneous coronary intervention (PCI)), and adults with angina or angiographically defined coronary artery disease (CAD). RCTs had to report at least one of the following outcomes: mortality (total- or cardiac-related); cardiac morbidity (MI, revascularisation procedures); or participant-reported levels of depression, anxiety, or stress.

DATA COLLECTION AND ANALYSIS

Two review authors independently screened titles and abstracts of all references for eligibility. A lead review author extracted study data, which a second review author checked. We contacted study authors to obtain missing information.

MAIN RESULTS

This review included 35 studies which randomised 10,703 people with CHD (14 trials and 2577 participants added to this update). The population included mainly men (median 77.0%) and people post-MI (mean 65.7%) or after undergoing a revascularisation procedure (mean 27.4%). The mean age of participants within trials ranged from 53 to 67 years. Overall trial reporting was poor, with around a half omitting descriptions of randomisation sequence generation, allocation concealment procedures, or the blinding of outcome assessments. The length of follow-up ranged from six months to 10.7 years (median 12 months). Most studies (23/35) evaluated multifactorial interventions, which included therapies with multiple therapeutic components. Ten studies examined psychological interventions targeted at people with a confirmed psychopathology at baseline and two trials recruited people with a psychopathology or another selecting criterion (or both). Of the remaining 23 trials, nine studies recruited unselected participants from cardiac populations reporting some level of psychopathology (3.8% to 53% with depressive symptoms, 32% to 53% with anxiety), 10 studies did not report these characteristics, and only three studies excluded people with psychopathology.Moderate quality evidence showed no risk reduction for total mortality (risk ratio (RR) 0.90, 95% confidence interval (CI) 0.77 to 1.05; participants = 7776; studies = 23) or revascularisation procedures (RR 0.94, 95% CI 0.81 to 1.11) with psychological therapies compared to usual care. Low quality evidence found no risk reduction for non-fatal MI (RR 0.82, 95% CI 0.64 to 1.05), although there was a 21% reduction in cardiac mortality (RR 0.79, 95% CI 0.63 to 0.98). There was also low or very low quality evidence that psychological interventions improved participant-reported levels of depressive symptoms (standardised mean difference (SMD) -0.27, 95% CI -0.39 to -0.15; GRADE = low), anxiety (SMD -0.24, 95% CI -0.38 to -0.09; GRADE = low), and stress (SMD -0.56, 95% CI -0.88 to -0.24; GRADE = very low).There was substantial statistical heterogeneity for all psychological outcomes but not clinical outcomes, and there was evidence of small-study bias for one clinical outcome (cardiac mortality: Egger test P = 0.04) and one psychological outcome (anxiety: Egger test P = 0.012). Meta-regression exploring a limited number of intervention characteristics found no significant predictors of intervention effects for total mortality and cardiac mortality. For depression, psychological interventions combined with adjunct pharmacology (where deemed appropriate) for an underlying psychological disorder appeared to be more effective than interventions that did not (β = -0.51, P = 0.003). For anxiety, interventions recruiting participants with an underlying psychological disorder appeared more effective than those delivered to unselected populations (β = -0.28, P = 0.03).

AUTHORS' CONCLUSIONS

This updated Cochrane Review found that for people with CHD, there was no evidence that psychological treatments had an effect on total mortality, the risk of revascularisation procedures, or on the rate of non-fatal MI, although the rate of cardiac mortality was reduced and psychological symptoms (depression, anxiety, or stress) were alleviated; however, the GRADE assessments suggest considerable uncertainty surrounding these effects. Considerable uncertainty also remains regarding the people who would benefit most from treatment (i.e. people with or without psychological disorders at baseline) and the specific components of successful interventions. Future large-scale trials testing the effectiveness of psychological therapies are required due to the uncertainty within the evidence. Future trials would benefit from testing the impact of specific (rather than multifactorial) psychological interventions for participants with CHD, and testing the targeting of interventions on different populations (i.e. people with CHD, with or without psychopathologies).

From Vitality to Vital Exhaustion and Other States of "Tense Tiredness": A New Biopsychosocial Risk Domain

Fatigue is a common prodromal symptom for various medical conditions, including acute myocardial infarction. Fatigue is also the core component of vital exhaustion, which consists of a specific triad: excessive fatigue, increased irritability, and feelings of demoralization. In this issue of Psychosomatic Medicine, Frestad and Prescott present a meta-analysis of 16 studies, involving 53,337 participants, which found vital exhaustion to be associated with an increased risk of incident coronary heart disease (CHD) and recurrent cardiac events among individuals with established CHD. After discussing methodological limitations of the studies included in this meta-analysis, we describe these findings in terms of a larger genre of risk that is biopsychosocial in origin and tied to two types of tiredness: "calm tiredness" and "tense tiredness." The former is regenerative, while the latter enhances disease risk. We propose that besides vital exhaustion, other symptoms of negative affect may combine with tiredness to produce increased clinical risk, such as the presence of depressed mood, an inability to relax or recover after work, and symptoms of burnout. We further propose that vital exhaustion can be considered as part of a larger paradigm, ranging from a positive state of vitality to a negative state of exhaustion of vitality. We conclude this editorial by emphasizing the importance of improving vitality and the need to clarify biobehavioral mechanisms that play a role in the association between vital exhaustion and adverse CHD outcomes. New interventions are needed that target reducing exhaustion and improving vitality for individuals at high risk of CHD.

Efficacy of psychosocial interventions on psychological outcomes among people with cardiovascular diseases: a systematic review and meta-analysis

OBJECTIVES

This systematic review aimed to examine empirical evidence concerning the efficacy of psychosocial interventions in ameliorating the psychosocial problems of people with cardiovascular diseases (CVDs).

METHODS

A comprehensive literature search was undertaken to identify both published and non-published English randomised controlled trials (RCTs) from 2000 to 2015. Two reviewers independently screened, assessed risks for bias, and extracted data. Comprehensive meta-analysis software was used to analyse the extracted data. Hedges's g effect size was used to determine the effects of psychosocial interventions.

RESULTS

Thirty studies were included in the review but only 18 studies reported significant short-term effects of psychosocial interventions in CVD patients. Most studies did not report long-term effects. Average effect sizes for stress, anxiety, depression, and combined depression/anxiety were 0.34, 1.04, 0.42 and 0.67 respectively at post-tests. Those numbers became 0.09, 0.65, 0.22 and 0.09 at follow-up assessments. Psychosocial programmes with psychoeducation and stress management helped reduce patients' stress and anxiety levels. Programmes including psychotherapy, counselling, mindfulness-based intervention (MBI), and stress management helped mitigate depression and anxiety.

CONCLUSIONS

The findings support the efficacy of some psychosocial interventions in people with CVDs.

PRACTICE IMPLICATIONS

Healthcare providers should monitor patients' psychological problems and may integrate psychosocial interventions as part of treatment plans.

Cognitive behaviour therapy in women with fibromyalgia: A randomized clinical trial

Background and aims

Stress has been pointed out as an important influential factor in the development and maintaining of the fibromyalgia syndrome (FMS) . Since stress may worsen the pain experience, the development of individual strategies for coping with stress is essential to reduce the impact of FMS on daily life. The aim of the study was to investigate whether a group based stress management cognitive behaviour therapy (CBT) programme could influence self-reported stress, wellbeing and life control, as well as self-reported pain behaviour in female FMS patients.

Methods

48 female FMS patient were randomized into a cognitive behaviour therapy treatment group (n = 24) and a waitlist control group (n = 24) . When the 6 months waitlist period was over the control group received the same CBT programme. This allowed two analytical approaches, one based on the randomized controlled trial design and one based on a before-and-after design to improve the statistical power of the study. Four psychometric instruments were used: The West Haven-Yale Multidimensional Pain Inventory (three parts, MPI-1 to MPI-3), the Maastricht Questionnaire, the Everyday Life Stress, and the Montgomery-Åsberg Depression rating scale – self-reported. Primary outcome was the MPI-1 dimension ‘life control’, secondary outcomes were the MPI-1 dimensions ‘interference’, ‘affective distress’ and ‘support from spouses or significant others’, the various MPI-2 dimensions, the ‘general activity level’ in the MPI-3 dimension, and ‘vital exhaustion’, ‘stress behaviour’, and ‘depression’. The only tertiary outcome was the MPI-1 dimension ‘pain severity’.

Results

In the RCT design the West Haven-Yale Multidimensional Pain Inventory dimensions ‘life control’, ‘interference from pain’, ‘affective distress’, ‘support from spouses or significant others’, and ‘distracting responses’ and ratings for depression improved in the treatment group as compared with the control group. In the before-and after design these improvements were maintained and enhanced during 1-year follow-up, and so was the ‘vital exhaustion’ and ‘stress behaviour’. ‘Pain severity’ was rated higher after the intervention.

Conclusions

Cognitive behaviour therapy improved the life control in a female population with FMS. Coping behaviour in response to chronic pain was improved at the same time and in spite of higher subjective ratings of pain. Positive effects were seen on depression, vital exhaustion and stress behaviour. The effects of therapy were maintained and enhanced during the follow up period. It appears that women with FMS after the CBT treatment, according to this protocol obtained tools leading to better acceptance of their disorder.

Implications

FMS is a disorder with great therapeutic challenges. Total abolishment of pain symptoms is extremely difficult or impossible to achieve. Thus, the development of individual strategies for coping with pain is essential to reduce its impact on daily life. Since stress may worsen the pain experience, coping with stress might be a promising route to accomplishing that goal. In evaluations of interventions for pain it is important to monitor the effect on behaviour responses to pain and not only ratings of pain itself.

Change in positive affect during outpatient cardiac rehabilitation predicts vital exhaustion in patients with coronary heart disease

Vital exhaustion is an acknowledged psychosocial risk factor of incident coronary heart disease (CHD) and recurrent CHD events. Little is known about trajectories in vital exhaustion in patients with CHD and the factors predicting this change. We hypothesized that vital exhaustion would decrease during outpatient cardiac rehabilitation and that an increase in positive affect over time would be associated with decreased vital exhaustion at discharge from cardiac rehabilitation. We also explored the role of the patient's sex in this context. Vital exhaustion was reduced during outpatient cardiac rehabilitation, especially in patients who experienced an increase in positive affect over time (p < .001). This relationship was significant in men (p < .001) but not in women (p = .11).

Psychological interventions for coronary heart disease: cochrane systematic review and meta-analysis

BACKGROUND

Depression and anxiety are common in cardiac patients, and psychological interventions may also be used as part of general cardiac rehabilitation programs.

PURPOSE

This study aims to estimate effects of psychological interventions on mortality and psychological symptoms in this group, updating an existing Cochrane Review.

METHOD

Systematic review and meta-regression analyses of randomized trials evaluating a psychological treatment delivered by trained staff to patients with a diagnosed cardiac disease, with a follow-up of at least 6 months, were used.

RESULTS

There was no strong evidence that psychological intervention reduced total deaths, risk of revascularization, or non-fatal infarction. Psychological intervention did result in small/moderate improvements in depression and anxiety, and there was a small effect for cardiac mortality.

CONCLUSION

Psychological treatments appear effective in treating patients with psychological symptoms of coronary heart disease. Uncertainty remains regarding the subgroups of patients who would benefit most from treatment and the characteristics of successful interventions.

Vital exhaustion and markers of low-grade inflammation in healthy adults: the Amsterdam Growth and Health Longitudinal Study

This study analyses distinct trajectories of vital exhaustion (VE; a measure of mental health incorporating signs of stress and depression) over a period of 15 years in healthy adults and investigates further the consequences for markers of low-grade inflammation as indicators of cardiovascular disease risk. Data of 341 participants of the Amsterdam Growth and Health Longitudinal Study were utilized. VE was measured by the Maastricht Questionnaire. Markers of low-grade inflammation included interleukin-6, interleukin-8 and tumour necrosis factor-α. Distinct trajectories of VE were obtained by latent class growth models, and consequences for markers of low-grade inflammation of the trajectories were analysed by linear regressions. We found comparable trajectories of VE for men and women; a 'never vitally exhausted' subgroup (16.9% and 25.1%, respectively), a 'stable preclinical VE' subgroup (51.7% and 68.1%) and a 'chronic VE state' subgroup (31.5% and 6.7%). The subgroups had similar levels of the markers investigated. This study is the first to analyse VE longitudinally in healthy adults and indicates that although distinct trajectories of VE were identified, differential consequences for cardiovascular disease risk were unapparent.

A meta-analysis of mental health treatments and cardiac rehabilitation for improving clinical outcomes and depression among patients with coronary heart disease

OBJECTIVE

To quantify the efficacy of mental health (antidepressants & psychotherapies) and cardiac rehabilitation treatments for improving secondary event risk and depression among patients with coronary heart disease (CHD).

METHODS

Using meta-analytic methods, we evaluated mental health and cardiac rehabilitation therapies for a) reducing secondary events and 2) improving depression severity in patients with CHD. Key word searches of PubMed and Psychlit databases and previous reviews identified relevant trials.

RESULTS

Eighteen mental health trials evaluated secondary events and 22 trials evaluated depression reduction. Cardiac rehabilitation trials for the same categories numbered 17 and 13, respectively. Mental health treatments did not reduce total mortality (absolute risk reduction [ARR] = -0.001, confidence interval [95% CI] = -0.016 to 0.015; number needed to treat [NNT] = ∞), showed moderate efficacy for reducing CHD events (ARR = 0.029, 95% CI = 0.007 to 0.051; NNT = 34), and a medium effect size for improving depression (Cohen d = 0.297). Cardiac rehabilitation showed similar efficacy for treating depression (d = 0.23) and reducing CHD events (ARR = 0.017, 95% CI = 0.007 to 0.026; NNT = 59) and reduced total mortality (ARR = 0.016, 95% CI = 0.005 to 0.027; NNT = 63).

CONCLUSIONS

Among patients with CHD, mental health treatments and cardiac rehabilitation may each reduce depression and CHD events, whereas cardiac rehabilitation is superior for reducing total mortality risk. The results support a continued role for mental health treatments and a larger role for mental health professionals in cardiac rehabilitation.

Characteristics of psychological interventions that improve depression in people with coronary heart disease: a systematic review and meta-regression

OBJECTIVE

Despite previous intervention trials, it is unclear which psychological treatments are most effective for people with coronary heart disease (CHD). We have conducted a systematic review with meta-regression to identify the characteristics of psychological interventions that improve depression and depressive symptoms among people with CHD.

METHODS

Searches of multiple electronic databases up to March 2012 were conducted, supplemented by hand-searching of identified reviews and citation tracing of eligible studies. Studies were included if they reported a randomized controlled trial of a psychological intervention for people with CHD and included depression as an outcome. Data on main effects and characteristics of interventions were extracted from eligible studies. Standardized mean differences (SMDs) were calculated for each study and pooled using random-effects models. Random-effects multivariate meta-regression was performed to identify treatment characteristics associated with improvements in depression.

RESULTS

Sixty-four independent treatment comparisons were identified. Psychological interventions improved depression, although the effect was small (SMD=0.18, p<.001). Problem solving (SMD=0.34), general education (SMD=0.19), skills training (SMD=0.25), cognitive-behavioral therapy (CBT; SMD=0.23), and relaxation (SMD=0.15) had small effects on CHD patients who were recruited irrespective of their depression status. Among high-quality trials of depressed CHD patients, only CBT showed significant but small effects (SMD=0.31). When entered into multivariable analysis, no individual treatment component significantly improved depression.

CONCLUSIONS

CBT and problem solving should be considered for inclusion in future treatment developments and randomized controlled trials. However, the effects are small in magnitude, and there is room to develop new interventions that may be more effective.

Burnout among foreign-born and native Swedish women: a longitudinal study

The authors of this study addressed burnout experiences (generally defined as chronic depletion of an individual's energetic resources') over time in relation to other factors (e.g., distress, sleep difficulties, job demands, etc.) among foreign-born women and Swedish native women living in Stockholm. The study design was a longitudinal panel survey with two waves one year apart. In the first wave, 3,616 of 6,000 randomly selected women took part, and 2,300 of the initial 3,616 women also participated in the second wave; 427 were foreign-born women, and 1,873 were Swedish native women. Baseline/emerging distress, emerging sleep difficulties, worsening general social support, job demands at baseline/escalating during the assessment period, emerging unemployment, constraints in social support at work, and sustained/emerging financial strain were associated with future burnout, regardless of background. More foreign-born women than Swedish native women reported burnout, with these differences maintained at one-year follow-up. The factors related to burnout were largely the same in both groups, but smoking and cardiovascular disease were related to burnout only among foreign-born women. Younger age, job demands, and working hours were associated with burnout among Swedish native women. The authors found that the women had concurrent problems such as burnout, distress, and sleep problems, but foreign background was not independently related to burnout.

Psychological interventions for coronary heart disease

BACKGROUND

Psychological symptoms are strongly associated with coronary heart disease (CHD), and many psychological treatments are offered following cardiac events or procedures.

OBJECTIVES

Update the existing Cochrane review to (1) determine the independent effects of psychological interventions in patients with CHD (principal outcome measures included total or cardiac-related mortality, cardiac morbidity, depression, and anxiety) and (2) explore study-level predictors of the impact of these interventions.

SEARCH STRATEGY

The original review searched Cochrane Controleed Trials Register (CCTR, Issue 4, 2001), MEDLINE, EMBASE, PsycINFO, and CINAHL to December 2001. This was updated by searching the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE and EMBASE, PsycINFO and CINAHL from 2001 to January 2009. In addition, we searched reference lists of papers, and expert advice was sought for the original and update review.

SELECTION CRITERIA

Randomised controlled trials of psychological interventions compared to usual care, administered by trained staff. Only studies estimating the independent effect of the psychological component with a minimum follow-up of six months. Adults with specific diagnosis of CHD.

DATA COLLECTION AND ANALYSIS

Titles and abstracts of all references screened for eligibility by two reviewers independently; data extracted by the lead author and checked by a second reviewer. Authors contacted where possible to obtain missing information.

MAIN RESULTS

There was no strong evidence that psychological intervention reduced total deaths, risk of revascularisation, or non-fatal infarction. Amongst a smaller group of studies reporting cardiac mortality there was a modest positive effect of psychological intervention (relative risk: 0.80 (95% CI 0.64 to 1.00)). Furthermore, psychological intervention did result in small/moderate improvements in depression, standardised mean difference (SMD): -0.21 (95% CI -0.35, -0.08) and anxiety, SMD: -0.25 (95% CI -0.48 to -0.03). Results for mortality indicated some evidence of small-study bias, though results for other outcomes did not. Meta regression analyses revealed four significant predictors of intervention effects on depression were found: (1) an aim to treat type-A behaviours (ß = -0.32, p = 0.03) were more effective than other interventions. In contrast, interventions which (2) aimed to educate patients about cardiac risk factors (ß = 0.23, p = 0.03), (3) included client-led discussion and emotional support as core therapeutic components (ß = 0.31, p < 0.01), or (4) included family members in the treatment process (ß = 0.26, p < 0.01) were significantly less effective.

AUTHORS' CONCLUSIONS

Psychological treatments appear effective in treating psychological symptoms of CHD patients. Uncertainly remains regarding the subgroups of patients who would benefit most from treatment and the characteristics of successful interventions.

Cognitive-behavioural therapy for depression in people with a somatic disease: meta-analysis of randomised controlled trials

BACKGROUND

Meta-analyses on psychological treatment for depression in individuals with a somatic disease are limited to specific underlying somatic diseases, thereby neglecting the generalisability of the interventions.

AIMS

To examine the effectiveness of cognitive-behavioural therapy (CBT) for depression in people with a diversity of somatic diseases.

METHOD

Meta-analysis of randomised controlled trials evaluating CBT for depression in people with a somatic disease. Severity of depressive symptoms was pooled using the standardised mean difference (SMD).

RESULTS

Twenty-nine papers met inclusion criteria. Cognitive-behavioural therapy was superior to control conditions with larger effects in studies restricted to participants with depressive disorder (SMD = -0.83, 95% CI -1.36 to -0.31, P<0.001) than in studies of participants with depressive symptoms (SMD = -0.16, 95% CI -0.27 to -0.06, P = 0.001). Subgroup analyses showed that CBT was not superior to other psychotherapies.

CONCLUSIONS

Cognitive-behavioural therapy significantly reduces depressive symptoms in people with a somatic disease, especially in those who meet the criteria for a depressive disorder.

Impact and clinical management of depression in patients with coronary artery disease

The rates of major adverse coronary events, including recurrent ischemic events and death, in patients with coronary artery disease (CAD) have been shown to be significantly increased in patients with depression. In addition, health care costs are higher and health-related quality of life is lower in depressed patients with CAD. Several pathophysiologic mechanisms have been proposed for the association of increased events seen in this population. Studies have focused on antidepressants (specifically, selective serotonin reuptake inhibitors and mirtazapine), psychotherapy (cognitive behavioral therapy and interpersonal psychotherapy), and a wide range of other nonpharmacologic interventions. Pharmacologic and nonpharmacologic treatments are known to improve depressive symptoms in patients with CAD, but their effects on outcomes such as mortality and hospital admissions remain controversial. If treatment of depression is warranted, strategies should include sertraline or citalopram, with or without cognitive behavioral therapy, based on the known efficacy and safety of the drugs in this population. Nonpharmacologic therapy such as aerobic exercise has been shown to improve not only depression but also cardiovascular health. When selecting an appropriate antidepressant, clinicians should consider their patients' comorbid conditions and the potential for drug interactions, and treatment should be frequently monitored. Screening for depression in patients with cardiac disease should be instituted on a routine basis by using either case-finding or symptom-triggered approaches. Based on the high prevalence of depression and its known adverse effects in patients with CAD, future research is needed to help determine the role of antidepressants and nonpharmacologic strategies in improving outcomes in patients with both comorbidities.

A systematic review of community-based health interventions on depression for older adults with heart disease

PURPOSE

This systematic review examined the effectiveness of community-based heart-health interventions on depression outcomes among homebound elderly (64 years and older) with heart disease.

DESIGN AND METHODS

A comprehensive literature search and meta analysis was performed to evaluate randomized controlled trials examining outpatient or home-based interventions. Methodological quality was assessed by standard criteria developed by the Cochrane Collaborative Initiative.

RESULTS

Fifteen studies met our inclusion criteria and all measured depression outcomes. Studies differed in scope and methodological rigor and sample sizes varied widely. Problems in treatment fidelity and masking of group assignment were noted. Great variability was found in depression outcomes due to the differences in methodology and intervention. Five studies reported significant treatment effect on depression; three of those employed home-based interventions and two were outpatient-clinic interventions. Ten studies were included in the meta analysis and the effect sizes (ESs) ranged from -0.39 (in favor of control group) to 0.65 (in favor of treatment group). The mean weighted ES was 0.11 and six studies showed positive ESs.

IMPLICATIONS

Mixed evidence for community-based heart disease interventions on depression outcomes was found. Future research should include sub-analysis of ESs of interventions on depression outcomes by different demographic characteristics of the study sample, common depression outcome measures, and different follow-up periods.

Vitality and recurrent event risk in acute myocardial infarction survivors

Background

Low vitality, characterized by fatigue and lack of energy, is common among survivors of acute myocardial infarction (AMI) and has been shown to be associated with increased risk of primary and secondary cardiac events. The goal of this study was to determine whether an association between vitality and recurrent cardiac events (nonfatal MI, cardiac death) among acute MI survivors persists after controlling for possible physiological and psychological confounders.

Design and methods

Incident AMI survivors ( n = 1328) from Erie and Niagara (New York) county hospitals were enrolled and followed up to 9 years. Vitality was measured by the Short Form-36 on a 0–100 scale approximately 4 months post-AMI. Cox proportional hazards models were developed to assess the vitality-recurrent event association controlling for traditional cardiovascular disease risk factors, index MI severity, and psychological correlates of vitality.

Results

Low-vitality individuals at baseline were more likely females, of higher BMI, smoking, diabetic, less physically active, and to have worse depression scores. Vitality was not strongly associated with MI severity markers. Lower vitality scores were associated with increased risk of recurrent cardiac events: adjusted hazard ratios (95% CI) for vitality scores 51–79, 21–50, and ≤ 20 (compared with ≥ 80) were 1.2 (0.8, 1.8), 1.4 (0.9, 2.2), and 2.9 (1.5, 5.4), respectively ( Ptrend = 0.005).

Conclusion

Low vitality was associated with increased risk of recurrent cardiac events among AMI survivors after controlling for physiological and psychological confounders. Mechanistic links with vitality should be sought as interventional targets.

Income and recurrent events after a coronary event in women

Strong evidence supports the existence of a social gradient in poor prognosis in patients with coronary heart disease (CHD). However, knowledge regarding what factors may explain this relationship is limited. We aimed to analyze in women CHD patients the association between personal income and recurrent events and to determine whether lifestyle, biological and psychosocial factors contribute to the explanation of this relationship. Altogether 188 women hospitalized for a cardiac event were assessed for personal income, demographic factors, lipids, inflammatory markers, cortisol, creatinine, lifestyle and psychosocial factors, i.e. alcohol consumption, smoking habits, body-mass index, depressive symptoms, anxiety, vital exhaustion, availability of social interaction, hostility and anger-related characteristics and were followed for cardiovascular death and recurrent acute myocardial infarction (AMI). During the 6-year follow-up 18 patients deceased and 31 experienced cardiovascular death or non-fatal AMI. After adjustment for confounders, patients with medium and high income had lower risk for recurrent events relative to those with low income (HR (95% CI): 0.38 (0.15-0.97) and 0.39 (0.17-0.93), respectively). Controlling for smoking reduced by 12.8% the risk for recurrent events associated with high versus low income, while adjusting for depression decreased the risk for middle versus low income by 13.5%. Anger symptoms explained 16.7% of the risk for recurrent events associated with middle versus low income and 10.2% of the risk for high versus low income. We suggest that in women with CHD low income is associated with recurrent events and that smoking, depressive symptomatology and anger symptoms may contribute to the explanation of this relationship.
