Combined exercise and cognitive behavioral therapy improves outcomes in patients with heart failure

THE LONG-TERM EFFICACY OF ACUTE-PHASE PSYCHOTHERAPY FOR DEPRESSION: A META-ANALYSIS OF RANDOMIZED TRIALS

BACKGROUND

Understanding the effectiveness of treatment for depression in both the short term and long term is essential for clinical decision making. The present meta-analysis examined treatment effects on depression and quality of life in acute-phase psychotherapeutic interventions compared to no treatment control groups for adult depression at 6 months or longer postrandomization.

METHODS

A systematic literature search resulted in 44 randomized controlled trials with 6,096 participants. Acute-phase psychotherapy was compared to control groups at 6-month or longer postrandomization. Odds ratios of a positive outcome were calculated.

RESULTS

Psychotherapy outperformed control groups at 6 months or longer postrandomization (OR = 1.92, 95% CI: 1.60-2.31, P < .001). Heterogeneity was moderate (I²: 65, 95% CI: 53-74, P < .001). However, effects significantly decreased with longer follow-up periods. Additionally, a small positive effect of psychotherapy was observed for quality of life, while similar effects were obtained in separate analyses of each type of psychotherapy, with the exception of nondirective supportive therapy. Studies that provided booster sessions had better treatment results compared with studies that did not provide any further sessions. Finally, we found that trials on psychotherapy aimed at major depressive disorder (MDD) had better outcomes than those that were aimed at elevated depressive symptoms.

CONCLUSIONS

There is substantial evidence that acute-phase psychotherapy results in a better treatment effects on depression and quality of life in the long term for adult patients with depression.

Mental Fitness for patients with acute coronary syndrome: A randomized clinical trial

OBJECTIVES

The aim of this study was to verify the efficacy of a manualized, cognitively oriented psychological intervention, called Mental Fitness, in improving the mental and physical health of patients with acute coronary syndrome (ACS). Mental Fitness is a small-group four-session treatment aimed at increasing awareness of one's own bodily perceptions, emotions, and thoughts and is overall tailored on participants' perception of control over their health.

DESIGN

Prospective randomized controlled single-blind trial.

METHODS

Patients with ACS were recruited within a week from their acute cardiac event. Patients in the intervention group underwent one of two variants of Mental Fitness, depending on their perceived (internal or external) control over their health. Patients in the control group underwent standard treatment. All the patients were submitted to a clinical and psychological follow-up for 8 months.

RESULTS

The patients who underwent the Mental Fitness intervention (N = 31) showed, compared to the control patients (N = 34), increased quality of life in its physical, psychological, social and environmental domains, more functional emotional and problem-centred coping strategies, and higher emotional awareness. They also showed improved high-density lipoprotein cholesterol, triglycerides, heart rate, and left ventricular ejection fraction compared to the controls. In addition, they were more successful in maintaining physical exercise.

CONCLUSIONS

This study demonstrates the efficacy of Mental Fitness in modifying specific psychological and physical variables conditioning cardiological patients' prognosis. It also confirms the importance of differentiating psychological interventions based on the psychological characteristics of the patients. Statement of contribution What is already known on this subject? Traditional symptom-based interventions in heart disease are aimed at diagnosing and reducing psychological symptomatology (e.g., depression), but recent work has shown the usefulness of orienting psychological interventions to patients' representations of themselves and of the world and to how such representations influence their thoughts, feelings, and behaviours (e.g., Chiavarino et al., ). What does this study add? Mental Fitness, by working on awareness of bodily perceptions, emotions, and thoughts, leads to positive changes in physical and psychological health. Mental Fitness is a cost-effective psychological intervention that adds significantly to the effectiveness of standard medical care.

The Effectiveness of a Nurse-Led Cognitive-Behavioral Therapy on the Quality of Life, Self-Esteem and Mood Among Filipino Patients Living With Heart Failure: a Randomized Controlled Trial

AIMS/OBJECTIVES

The diagnosis and complications associated with heart failure (HF) have been very well established to adversely impact an individual's physical and psychosocial well-being, and interventions such as cognitive-behavioral techniques have demonstrated potential positive benefits among patients with HF. However, the effects of such interventions among Filipino HF patients have not been studied. This study aimed to determine the effectiveness of a nurse-led cognitive-behavioral intervention program on the quality of life, self-esteem and mood among Filipino patients with HF.

METHODS

A randomized control two-group design with repeated measures and collected data before and after the intervention was used in this study. Participants were assigned to either the control (n=48) or the intervention group (n=52). Control group participants received traditional care. Intervention participants underwent a 12-week nurse-led cognitive-behavioral intervention program focusing on patient education, self-monitoring, skills training, cognitive restructuring and spiritual development. Measures of quality of life, self-esteem and mood were obtained at baseline and after the intervention.

RESULTS

At baseline, participants in both groups have poor quality of life, low self-esteem, and moderate depressive symptom scores. After the 12-week intervention period, participants in the intervention group had significant improvement in their quality of life, self-esteem and mood scores compared with those who received only standard care.

CONCLUSION

Nurse-led cognitive-behavioral intervention is an effective strategy in improving the quality of life, self-esteem and mood among Filipino patients living with HF. It is recommended that this intervention be incorporated in the optimal care of patients with this cardiac condition.

Dropout from exercise randomized controlled trials among people with depression: A meta-analysis and meta regression

OBJECTIVE

Exercise has established efficacy in improving depressive symptoms. Dropouts from randomized controlled trials (RCT's) pose a threat to the validity of this evidence base, with dropout rates varying across studies. We conducted a systematic review and meta-analysis to investigate the prevalence and predictors of dropout rates among adults with depression participating in exercise RCT's.

METHOD

Three authors identified RCT's from a recent Cochrane review and conducted updated searches of major electronic databases from 01/2013 to 08/2015. We included RCT's of exercise interventions in people with depression (including major depressive disorder (MDD) and depressive symptoms) that reported dropout rates. A random effects meta-analysis and meta regression were conducted.

RESULTS

Overall, 40 RCT's were included reporting dropout rates across 52 exercise interventions including 1720 people with depression (49.1 years (range=19-76 years), 72% female (range=0-100)). The trim and fill adjusted prevalence of dropout across all studies was 18.1% (95%CI=15.0-21.8%) and 17.2% (95%CI=13.5-21.7, N=31) in MDD only. In MDD participants, higher baseline depressive symptoms (β=0.0409, 95%CI=0.0809-0.0009, P=0.04) predicted greater dropout, whilst supervised interventions delivered by physiotherapists (β=-1.2029, 95%CI=-2.0967 to -0.3091, p=0.008) and exercise physiologists (β=-1.3396, 95%CI=-2.4478 to -0.2313, p=0.01) predicted lower dropout. A comparative meta-analysis (N=29) established dropout was lower in exercise than control conditions (OR=0.642, 95%CI=0.43-0.95, p=0.02).

CONCLUSIONS

Exercise is well tolerated by people with depression and drop out in RCT's is lower than control conditions. Thus, exercise is a feasible treatment, in particular when delivered by healthcare professionals with specific training in exercise prescription.

Shortened questionnaires to assess anxiety and depression during in-hospital rehabilitation: clinical validation and cutoff scores

BACKGROUND

A postacute phase needs reliable routine screening instruments in order to identify the patients to be referred for a clinical interview with a psychologist. The aim of this study was to estimate the clinical cutoff scores of the anxiety and depression questionnaires and their clinical validity using a gold standard.

METHODS

The study involved 177 patients with pulmonary, cardiac, or neurological disease undergoing in-hospital rehabilitation. Receiver operating characteristic curves were used to determine the best concordance between questionnaire's scores and the gold standards.

RESULTS

There was a significant difference (P<0.001) between clinically anxious and depressed patients and nonclinical subjects. The receiver operating characteristic curve for anxiety indicated that the best area under the curve for State Anxiety Inventory is obtained with a cutoff point of 21 for males and 25 for females; for depression scores, the highest area under the curve for Depression Questionnaire-Reduced Form is obtained with a cutoff point of six for males and eight for females.

CONCLUSION

Using appropriate cutoff values, the State Anxiety Inventory and Depression Questionnaire-Reduced Form allow psychologists to optimize early clinical intervention strategies selecting patients with significant needs.

Patient-reported health status prior to cardiac resynchronisation therapy identifies patients at risk for poor survival and prolonged hospital stays

Background

Patient-reported factors have largely been neglected in search of predictors of response to cardiac resynchronisation therapy (CRT). The current study aimed to examine the independent value of pre-implantation patient-reported health status in predicting four-year survival and cardiac-related hospitalisation of CRT patients.

Methods

Consecutive patients (N = 139) indicated to receive a first-time CRT-defibrillator at the University Medical Center Utrecht were asked to complete a set of questionnaires prior to implantation. The Kansas City Cardiomyopathy Questionnaire (KCCQ) was used to assess heart failure-specific health status. Data on patients’ demographic, clinical and psychological characteristics at baseline, and on cardiac-related hospitalisations and all-cause deaths during a median follow-up of 3.9 years were obtained from purpose-designed questionnaires and patients’ medical records.

Results

Results of multivariable Cox regression analyses showed that poor patient-reported health status (KCCQ score < 50) prior to implantation was associated with a 2.5-fold increased risk of cardiac hospitalisation or all-cause death, independent of sociodemographic, clinical and psychological risk factors (adjusted hazard ratio 2.46, 95 % confidence interval (CI) 1.30–4.65). Poor health status was not significantly associated with the absolute number of cardiac-related hospital admissions, but with the total number of days spent in hospital during follow-up (adjusted incidence rate ratio 3.20, 95 % CI 1.88–5.44).

Conclusions

Patient-reported health status assessed prior to CRT identifies patients at risk for poor survival and prolonged hospital stays, independent of traditional risk factors. These results emphasise the importance of incorporating health status measures in cardiovascular research and patient management. Heart failure patients reporting poor health status should be identified and offered appropriate additional treatment programs.

Cognitive Behavior Therapy for Depression and Self-Care in Heart Failure Patients: A Randomized Clinical Trial

IMPORTANCE

Depression and inadequate self-care are common and interrelated problems that increase the risks of hospitalization and mortality in patients with heart failure (HF).

OBJECTIVE

To determine the efficacy of an integrative cognitive behavior therapy (CBT) intervention for depression and HF self-care.

DESIGN, SETTING, AND PARTICIPANTS

Randomized clinical trial with single-blind outcome assessments. Eligible patients were enrolled at Washington University Medical Center in St Louis between January 4, 2010, and June 28, 2013. The primary data analyses were conducted in February 2015. The participants were 158 outpatients in New York Heart Association Class I, II, and III heart failure with comorbid major depression.

INTERVENTIONS

Cognitive behavior therapy delivered by experienced therapists plus usual care (UC), or UC alone. Usual care was enhanced in both groups with a structured HF education program delivered by a cardiac nurse.

MAIN OUTCOMES AND MEASURES

The primary outcome was severity of depression at 6 months as measured by the Beck Depression Inventory. The Self-Care of Heart Failure Index Confidence and Maintenance subscales were coprimary outcomes. Secondary outcomes included measures of anxiety, depression, physical functioning, fatigue, social roles and activities, and quality of life. Hospitalizations and deaths were exploratory outcomes.

RESULTS

One hundred fifty-eight patients were randomized to UC (n = 79) or CBT (n = 79). Within each arm, 26 (33%) of the patients were taking an antidepressant at baseline. One hundred thirty-two (84%) of the participants completed the 6-month posttreatment assessments; 60 (76%) of the UC and 58 (73%) of the CBT participants completed every follow-up assessment (P = .88). Six-month depression scores were lower in the CBT than the UC arm on the Beck Depression Inventory (BDI-II) (12.8 [10.6] vs 17.3 [10.7]; P = .008). Remission rates differed on the BDI-II (46% vs 19%; number needed to treat [NNT] = 3.76; 95% CI, 3.62-3.90; P < .001) and the Hamilton Depression Scale (51% vs 20%; NNT = 3.29; 95% CI, 3.15-3.43; P < .001). The groups did not differ on the Self-Care Maintenance or Confidence subscales. The mean (SD) Beck Depression Inventory scores 6 months after randomization were lower in the CBT (12.8 [10.6]) than the UC arm (17.3 [10.7]), P = .008. There were no statistically significant differences between the groups on the Self-Care Maintenance or Confidence subscale scores or on physical functioning measures. Anxiety and fatigue scores were lower and mental- and HF-related quality of life and social functioning scores were higher at 6 months in the CBT than the UC arm, and there were fewer hospitalizations in the intervention than the UC arm.

CONCLUSIONS AND RELEVANCE

A CBT intervention that targets both depression and heart failure self-care is effective for depression but not for HF self-care or physical functioning relative to enhanced UC. Additional benefits include reduced anxiety and fatigue, improved social functioning, and better health-related quality of life.

Feasibility and Efficacy of a Self-Management Intervention for Insomnia in Stable Heart Failure

BACKGROUND

Chronic insomnia is common among patients with heart failure (HF) and may contribute to fatigue and poor function. However, to date there have been no randomized controlled trials focused on treatment of insomnia or daytime symptoms in this population.

OBJECTIVES

The purpose of this study was to examine the preliminary efficacy, feasibility, and acceptability of a self-management intervention (cognitive behavioral therapy [CBT-I]) for insomnia among patients with stable HF.

METHODS

We conducted a pilot randomized controlled trial (RCT) in which patients with stable Class I-III HF (n = 25/52.1% women; mean age = 59 ± 14.8 years) were randomized in groups to CBT-I (n = 29) or an attention control condition (HF self-management with sleep hygiene; n = 19). Participants completed 2 weeks of wrist actigraphy, the insomnia severity index, and measures of fatigue, depression, sleepiness, and functional performance at baseline and follow-up. We computed the size of the effects on the dependent variables and used MANOVA to evaluate the effects of CBT-I on insomnia and fatigue.

RESULTS

CBT-I was feasible and acceptable and had a statistically significant effect on insomnia and fatigue, while controlling for the effects of comorbidity and age.

CONCLUSIONS

CBT-I has short-term efficacy as a treatment for chronic insomnia among patients with stable HF. Future studies are needed to address its sustained effects.

Cognitive Behavioral Therapy for Insomnia in the Context of Cardiovascular Conditions

Cardiovascular disease (CVD) is the leading cause of death worldwide and is associated with high levels of morbidity, disability and poor quality of life. The prevalence of insomnia symptoms and diagnosis of insomnia are high among those with CVD. Although insomnia appears to be important to CVD, less is known about the effects of insomnia treatment on important biological, sleep, symptom, quality of life, functional and morbidity or mortality outcomes in people with or at-risk for CVD. The purposes of this paper are to review the literature on the effects of CBT-I on insomnia, sleep, daytime symptoms, function, and biological outcomes in the context of CVD and to suggest implications for future research and practice. Limited available evidence suggests that CBT-I improves biomarkers that may contribute to CVD risk. CBT-I shows promise as a way to improve cardiovascular morbidity associated with the negative biological consequences of chronic insomnia, as well as symptom burden, functional performance and quality of life in the large population of people who are living with chronic CVD and insomnia. Additional research is needed to answer basic questions about short and long term outcomes, the role of biomarkers, and optimal delivery methods of CBT-I in cardiac conditions.

A patient-centered perspective of treating depressive symptoms in chronic heart failure: What do patients prefer?

OBJECTIVE

To date, very little is known about the specific needs of patients with chronic heart failure (CHF) who must cope with depression. We therefore questioned CHF patients reporting depressive symptoms about their concerns and preferences regarding various psychosocial treatment options. After three-month, we determined how many patients had actually participated in a treatment.

METHODS

85 patients with CHF fulfilling the criteria of a depressive disorder according to the PHQ-9 were investigated. Data were analyzed using descriptive and frequency, as well as logistic regression analyses.

RESULTS

64.7% of the sample reported that they could envision adhering to supportive talks at longer intervals, whereas only 34.1% would accept an antidepressant. After three months, 24.7% of the patients had actually participated in a treatment. Generalized anxiety severity (GAD-7) was very closely associated with treatment preferences and treatment utilization: The higher the generalized anxiety severity, the more likely was the patients' disposition to begin an antidepressant and/or psychotherapy.

CONCLUSIONS

The most favoured treatment option was a low-threshold service with supportive talks.

PRACTICE IMPLICATIONS

Future studies investigating the improvement of patient-centred care in CHF patients should include measurements of generalized anxiety.

Exercise-based rehabilitation for heart failure: systematic review and meta-analysis

OBJECTIVE

To update the Cochrane systematic review of exercise-based cardiac rehabilitation (CR) for heart failure.

METHODS

A systematic review and meta-analysis of randomised controlled trials was undertaken. MEDLINE, EMBASE and the Cochrane Library were searched up to January 2013. Trials with 6 or more months of follow-up were included if they assessed the effects of exercise interventions alone or as a component of comprehensive CR programme compared with no exercise control.

RESULTS

33 trials were included with 4740 participants predominantly with a reduced ejection fraction (<40%) and New York Heart Association class II and III. Compared with controls, while there was no difference in pooled all-cause mortality between exercise CR with follow-up to 1 year (risk ratio (RR) 0.93; 95% CI 0.69 to 1.27, p=0.67), there was a trend towards a reduction in trials with follow-up beyond 1 year (RR 0.88; 0.75 to 1.02, 0.09). Exercise CR reduced the risk of overall (RR 0.75; 0.62 to 0.92, 0.005) and heart failure-specific hospitalisation (RR 0.61; 0.46 to 0.80, 0.0004) and resulted in a clinically important improvement in the Minnesota Living with Heart Failure questionnaire (mean difference: -5.8 points, -9.2 to -2.4, 0.0007). Univariate meta-regression analysis showed that these benefits were independent of the type and dose of exercise CR, and trial duration of follow- up, quality or publication date.

CONCLUSIONS

This updated Cochrane review shows that improvements in hospitalisation and health-related quality of life with exercise-based CR appear to be consistent across patients regardless of CR programme characteristics and may reduce mortality in the longer term. An individual participant data meta-analysis is needed to provide confirmatory evidence of the importance of patient subgroup and programme level characteristics (eg, exercise dose) on outcome.

Reasonable expectations: how much aerobic capacity, muscle strength, and quality of life can improve with exercise training in heart failure

In this article, the literature that describes the magnitude of functional and quality of life gains with a traditional moderate-intensity aerobic and resistance training programs is reviewed, and differences between the impact of exercise training in heart failure with preserved ejection fraction versus heart failure with reduced ejection fraction are discussed.

A dynamic view of comorbid depression and generalized anxiety disorder symptom change in chronic heart failure: the discrete effects of cognitive behavioral therapy, exercise, and psychotropic medication

PURPOSE

No previous study has reported upon comorbid depression and anxiety disorders and their treatment in heart failure (HF), which the current study has sought to document.

MATERIALS AND METHODS

Total 29 HF patients under psychiatric management underwent primary depression cognitive behavioral therapy (CBT; n = 15) or primary generalized anxiety disorder (GAD) CBT (n = 14), and participated in a community exercise program and standard physician care. Repeated measures analysis of variance assessed Patient Health Questionnaire (PHQ-9) and GAD-7 symptom change pre- and post-CBT treatment, and assessed the interaction effects of treatment type, exercise, anti-depressant and anxiolytic.

RESULTS

There was a significant time and treatment interaction effect that favored the primary GAD CBT group for reduction in PHQ symptoms (F(1, 24) = 4.52, p = 0.04). Analysis of PHQ-somatic symptoms also showed a significant main effect for participation in the exercise program (F(1, 24) = 4.21, p = 0.05) and a significant time and anxiolytic interaction (F(1, 24) = 3.98, p = 0.05). The average number of cardiac hospital readmissions favored the primary GAD CBT group (p = 0.05).

CONCLUSION

The findings support the use of multifaceted interventions in the rehabilitation of HF patients with comorbid psychiatric needs. Implications for Rehabilitation Comorbid depression and anxiety disorders are a clinical and research focus that deserves more attention in the treatment of heart failure patients. Cognitive behavioral therapy, exercise, and anxiolytic use was associated with significant changes in depression and anxiety though discrete effects were evident. Multifaceted interventions are most likely to be successful in the rehabilitation of HF patients with psychiatric needs.

Exercise-based rehabilitation for heart failure

BACKGROUND

Previous systematic reviews and meta-analyses consistently show the positive effect of exercise-based rehabilitation for heart failure (HF) on exercise capacity; however, the direction and magnitude of effects on health-related quality of life, mortality and hospital admissions in HF remain less certain. This is an update of a Cochrane systematic review previously published in 2010.

OBJECTIVES

To determine the effectiveness of exercise-based rehabilitation on the mortality, hospitalisation admissions, morbidity and health-related quality of life for people with HF. Review inclusion criteria were extended to consider not only HF due to reduced ejection fraction (HFREF or 'systolic HF') but also HF due to preserved ejection fraction (HFPEF or 'diastolic HF').

SEARCH METHODS

We updated searches from the previous Cochrane review. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (Issue1, 2013) from January 2008 to January 2013. We also searched MEDLINE (Ovid), EMBASE (Ovid), CINAHL (EBSCO) and PsycINFO (Ovid) (January 2008 to January 2013). We handsearched Web of Science, bibliographies of systematic reviews and trial registers (Controlled-trials.com and Clinicaltrials.gov).

SELECTION CRITERIA

Randomised controlled trials of exercise-based interventions with six months' follow-up or longer compared with a no exercise control that could include usual medical care. The study population comprised adults over 18 years and were broadened to include individuals with HFPEF in addition to HFREF.

DATA COLLECTION AND ANALYSIS

Two review authors independently screened all identified references and rejected those that were clearly ineligible. We obtained full-text papers of potentially relevant trials. One review author independently extracted data from the included trials and assessed their risk of bias; a second review author checked data.

MAIN RESULTS

We included 33 trials with 4740 people with HF predominantly with HFREF and New York Heart Association classes II and III. This latest update identified a further 14 trials. The overall risk of bias of included trials was moderate. There was no difference in pooled mortality between exercise-based rehabilitation versus no exercise control in trials with up to one-year follow-up (25 trials, 1871 participants: risk ratio (RR) 0.93; 95% confidence interval (CI) 0.69 to 1.27, fixed-effect analysis). However, there was trend towards a reduction in mortality with exercise in trials with more than one year of follow-up (6 trials, 2845 participants: RR 0.88; 95% CI 0.75 to 1.02, fixed-effect analysis). Compared with control, exercise training reduced the rate of overall (15 trials, 1328 participants: RR 0.75; 95% CI 0.62 to 0.92, fixed-effect analysis) and HF specific hospitalisation (12 trials, 1036 participants: RR 0.61; 95% CI 0.46 to 0.80, fixed-effect analysis). Exercise also resulted in a clinically important improvement superior in the Minnesota Living with Heart Failure questionnaire (13 trials, 1270 participants: mean difference: -5.8 points; 95% CI -9.2 to -2.4, random-effects analysis) - a disease specific health-related quality of life measure. However, levels of statistical heterogeneity across studies in this outcome were substantial. Univariate meta-regression analysis showed that these benefits were independent of the participant's age, gender, degree of left ventricular dysfunction, type of cardiac rehabilitation (exercise only vs. comprehensive rehabilitation), mean dose of exercise intervention, length of follow-up, overall risk of bias and trial publication date. Within these included studies, a small body of evidence supported exercise-based rehabilitation for HFPEF (three trials, undefined participant number) and when exclusively delivered in a home-based setting (5 trials, 521 participants). One study reported an additional mean healthcare cost in the training group compared with control of USD3227/person. Two studies indicated exercise-based rehabilitation to be a potentially cost-effective use of resources in terms of gain in quality-adjusted life years (QALYs) and life-years saved.

AUTHORS' CONCLUSIONS

This updated Cochrane review supports the conclusions of the previous version of this review that, compared with no exercise control, exercise-based rehabilitation does not increase or decrease the risk of all-cause mortality in the short term (up to 12-months' follow-up) but reduces the risk of hospital admissions and confers important improvements in health-related quality of life. This update provides further evidence that exercise training may reduce mortality in the longer term and that the benefits of exercise training on appear to be consistent across participant characteristics including age, gender and HF severity. Further randomised controlled trials are needed to confirm the small body of evidence seen in this review for the benefit of exercise in HFPEF and when exercise rehabilitation is exclusively delivered in a home-based setting.

The real world mental health needs of heart failure patients are not reflected by the depression randomized controlled trial evidence

INTRODUCTION

International depression screening guidelines in heart failure (HF) are partly based on depression treatment efficacy from randomized controlled trials (RCTs). Our aim was to test the external validity of depression RCT criteria in a sample of real-world HF patients.

METHODS

HF patients admitted to 3 hospitals in South Australia were referred to a HF psychologist if not already receiving current psychiatric management by psychologist or psychiatrist elsewhere. Screening and referral protocol consisted of the following; (a). Patient Health Questionnaire ≥ 10; (b). Generalized Anxiety Disorder Questionnaire ≥ 7); (c). positive response to 1 item panic attack screener; (d). evidence of suicidality. Patients were evaluated against the most common RCT exclusion criteria personality disorder, high suicide risk, cognitive impairment, psychosis, alcohol or substance abuse or dependency, bi-polar depression.

RESULTS

Total 81 HF patients were referred from 404 HF admissions, and 73 were assessed (age 60.6 ± 13.4, 47.9% female). Nearly half (47%) met at least 1 RCT exclusion criterion, most commonly personality disorder (28.5%), alcohol/substance abuse (17.8%) and high suicide risk (11.0%). RCT ineligibility criteria was more frequent among patients with major depression (76.5% vs. 46.2%, p<.01) and dysthymia (26.5% vs. 7.7%, p = .03) but not significantly associated with anxiety disorders. RCT ineligible patients reported greater severity of depression (M = 16.6 ± 5.0 vs. M = 12.9 ± 7.2, p = .02) and were higher consumers of HF psychotherapy services (M = 11.5 ± 4.7 vs. M = 8.5 ± 4.8, p = .01).

CONCLUSION

In this real-world sample comparable in size to recent RCT intervention arms, patients with depression disorders presented with complex psychiatric needs including comorbid personality disorders, alcohol/substance use and suicide risk. These findings suggest external validity of depression screening and RCTs could serve as a basis for level A guideline recommendations in cardiovascular diseases.

Risk factors for onset of depression after heart failure hospitalization

BACKGROUND

Depression is common in chronic heart failure (CHF) and associated with adverse outcomes. Knowing the risk factors for the development of depression at the early post-hospitalization phase may be a key factor of successful disease management programs. The aim of this study was therefore to identify the risk factors related to the onset of depression after heart failure hospitalization in patients with CHF.

METHODS

The study population included participants with an admission diagnosis of acute heart failure or exacerbation of CHF from a multicenter prospective cohort study. Patients completed clinical evaluation at discharge and functional and social status assessment at 1 month after discharge, and depressive symptoms using the Hospital Anxiety and Depression Scale (HADS-D) at discharge and 1-year later.

RESULTS

Of the 131 patients without depression at discharge, 29 (22.1%) had developed significant depressive symptoms (HADS-D ≥ 8) at 1-year follow-up. Multiple logistic regression demonstrated that previous ischemic heart disease [odds ratio (OR) 3.09, 95% confidence interval (CI) 1.15-8.33], participation restrictions (OR 0.43, 95% CI 0.26-0.70), and lack of satisfaction with social support (OR 0.48, 95% CI 0.29-0.79) were independent predictors of developing depression.

CONCLUSIONS

The three clinically accessible variables and targets for interventions identified as predictors in this study may help to guide the optimal post-discharge disease management planning for these patients who are at high risk for depression.

Depression and cardiovascular disease: a clinical review

Cardiovascular disease (CVD) and depression are common. Patients with CVD have more depression than the general population. Persons with depression are more likely to eventually develop CVD and also have a higher mortality rate than the general population. Patients with CVD, who are also depressed, have a worse outcome than those patients who are not depressed. There is a graded relationship: the more severe the depression, the higher the subsequent risk of mortality and other cardiovascular events. It is possible that depression is only a marker for more severe CVD which so far cannot be detected using our currently available investigations. However, given the increased prevalence of depression in patients with CVD, a causal relationship with either CVD causing more depression or depression causing more CVD and a worse prognosis for CVD is probable. There are many possible pathogenetic mechanisms that have been described, which are plausible and that might well be important. However, whether or not there is a causal relationship, depression is the main driver of quality of life and requires prevention, detection, and management in its own right. Depression after an acute cardiac event is commonly an adjustment disorder than can improve spontaneously with comprehensive cardiac management. Additional management strategies for depressed cardiac patients include cardiac rehabilitation and exercise programmes, general support, cognitive behavioural therapy, antidepressant medication, combined approaches, and probably disease management programmes.

Early cognitive behavioral therapy for depression after cardiac surgery

BACKGROUND

Despite high rates of postcardiac surgery depression, studies of depression treatment in this population have been limited.

OBJECTIVE

The aim of this study was to evaluate early cognitive behavioral therapy (CBT) in a home environment in patients recovering from cardiac surgery.

METHODS

: From July 2006 through October 2009, we conducted a randomized controlled trial and enrolled 808 patients who were screened for depressive symptoms using the Beck Depression Inventory (BDI) in the hospital and 1 month later. Patients were interviewed using the Structured Clinical Interview for DSM-IV; those who met criteria for clinical depression (n = 81) were randomized to CBT (n = 45) or usual care (UC; n = 36). After completion of the UC period, 25 individuals were offered later CBT (UC + CBT).

RESULTS

Main outcomes (depressive symptoms [BDI] and clinical depression [Structured Clinical Interview for DSM-IV]) were evaluated after 8 weeks using intention-to-treat principles and linear mixed models. Compared with the UC group, in the CBT group, there was greater decline in BDI scores (β = 1.41; 95% confidence interval [CI], 0.81-2.02; P = < .001) and greater remission of clinical depression (29 [64%] vs 9 [25%]; number need to treat, 2.5; 95% CI, 1.7-4.9; P < .001). Compared with the early CBT group (median time from surgery to CBT, 45.5 days) the later UC + CBT group (median time from surgery to CBT, 122 days) also experienced a reduction in BDI scores, but the group × time effect was smaller (β = 0.79; 95% CI, 0.10-1.47; P = .03) and remission rates between the 2 groups did not differ.

CONCLUSIONS

Early home CBT is effective in depressed postcardiac surgery patients. Early treatment is associated with greater symptom reduction than similar therapy given later after surgery.

Exercise for depression

BACKGROUND

Depression is a common and important cause of morbidity and mortality worldwide. Depression is commonly treated with antidepressants and/or psychological therapy, but some people may prefer alternative approaches such as exercise. There are a number of theoretical reasons why exercise may improve depression. This is an update of an earlier review first published in 2009.

OBJECTIVES

To determine the effectiveness of exercise in the treatment of depression in adults compared with no treatment or a comparator intervention.

SEARCH METHODS

We searched the Cochrane Depression, Anxiety and Neurosis Review Group's Controlled Trials Register (CCDANCTR) to 13 July 2012. This register includes relevant randomised controlled trials from the following bibliographic databases: The Cochrane Library (all years); MEDLINE (1950 to date); EMBASE (1974 to date) and PsycINFO (1967 to date). We also searched www.controlled-trials.com, ClinicalTrials.gov and the WHO International Clinical Trials Registry Platform. No date or language restrictions were applied to the search.We conducted an additional search of the CCDANCTR up to 1st March 2013 and any potentially eligible trials not already included are listed as 'awaiting classification.'

SELECTION CRITERIA

Randomised controlled trials in which exercise (defined according to American College of Sports Medicine criteria) was compared to standard treatment, no treatment or a placebo treatment, pharmacological treatment, psychological treatment or other active treatment in adults (aged 18 and over) with depression, as defined by trial authors. We included cluster trials and those that randomised individuals. We excluded trials of postnatal depression.

DATA COLLECTION AND ANALYSIS

Two review authors extracted data on primary and secondary outcomes at the end of the trial and end of follow-up (if available). We calculated effect sizes for each trial using Hedges' g method and a standardised mean difference (SMD) for the overall pooled effect, using a random-effects model risk ratio for dichotomous data. Where trials used a number of different tools to assess depression, we included the main outcome measure only in the meta-analysis. Where trials provided several 'doses' of exercise, we used data from the biggest 'dose' of exercise, and performed sensitivity analyses using the lower 'dose'. We performed subgroup analyses to explore the influence of method of diagnosis of depression (diagnostic interview or cut-off point on scale), intensity of exercise and the number of sessions of exercise on effect sizes. Two authors performed the 'Risk of bias' assessments. Our sensitivity analyses explored the influence of study quality on outcome.

MAIN RESULTS

Thirty-nine trials (2326 participants) fulfilled our inclusion criteria, of which 37 provided data for meta-analyses. There were multiple sources of bias in many of the trials; randomisation was adequately concealed in 14 studies, 15 used intention-to-treat analyses and 12 used blinded outcome assessors.For the 35 trials (1356 participants) comparing exercise with no treatment or a control intervention, the pooled SMD for the primary outcome of depression at the end of treatment was -0.62 (95% confidence interval (CI) -0.81 to -0.42), indicating a moderate clinical effect. There was moderate heterogeneity (I² = 63%).When we included only the six trials (464 participants) with adequate allocation concealment, intention-to-treat analysis and blinded outcome assessment, the pooled SMD for this outcome was not statistically significant (-0.18, 95% CI -0.47 to 0.11). Pooled data from the eight trials (377 participants) providing long-term follow-up data on mood found a small effect in favour of exercise (SMD -0.33, 95% CI -0.63 to -0.03).Twenty-nine trials reported acceptability of treatment, three trials reported quality of life, none reported cost, and six reported adverse events.For acceptability of treatment (assessed by number of drop-outs during the intervention), the risk ratio was 1.00 (95% CI 0.97 to 1.04).Seven trials compared exercise with psychological therapy (189 participants), and found no significant difference (SMD -0.03, 95% CI -0.32 to 0.26). Four trials (n = 300) compared exercise with pharmacological treatment and found no significant difference (SMD -0.11, -0.34, 0.12). One trial (n = 18) reported that exercise was more effective than bright light therapy (MD -6.40, 95% CI -10.20 to -2.60).For each trial that was included, two authors independently assessed for sources of bias in accordance with the Cochrane Collaboration 'Risk of bias' tool. In exercise trials, there are inherent difficulties in blinding both those receiving the intervention and those delivering the intervention. Many trials used participant self-report rating scales as a method for post-intervention analysis, which also has the potential to bias findings.

AUTHORS' CONCLUSIONS

Exercise is moderately more effective than a control intervention for reducing symptoms of depression, but analysis of methodologically robust trials only shows a smaller effect in favour of exercise. When compared to psychological or pharmacological therapies, exercise appears to be no more effective, though this conclusion is based on a few small trials.

Diagnosis and treatment of depression in patients with congestive heart failure: a review of the literature

CONTEXT

Major depressive disorder (MDD) can be challenging to diagnose in patients with congestive heart failure, who often suffer from fatigue, insomnia, weight changes, and other neurovegetative symptoms that overlap with those of depression. Pathophysiologic mechanisms (eg, inflammation, autonomic nervous system dysfunction, cardiac arrhythmias, and altered platelet function) connect depression and congestive heart failure.

OBJECTIVE

We sought to review the prevalence, diagnosis, neurobiology, and treatment of depression associated with congestive heart failure.

DATA SOURCES

A search of all English-language articles between January 2003 and January 2013 was conducted using the search terms congestive heart failure and depression.

STUDY SELECTION

We found 1,498 article abstracts and 19 articles (meta-analyses, systematic reviews, and original research articles) that were selected for inclusion, as they contained information about our focus on diagnosis, treatment, and pathophysiology of depression associated with congestive heart failure. The search was augmented with manual review of reference lists of articles from the initial search. Articles selected for review were determined by author consensus.

DATA EXTRACTION

The prevalence, diagnosis, neurobiology, and treatment of depression associated with congestive heart failure were reviewed. Particular attention was paid to the safety, efficacy, and tolerability of antidepressant medications commonly used to treat depression and how their side-effect profiles impact the pathophysiology of congestive heart failure. Drug-drug interactions between antidepressant medications and medications used to treat congestive heart failure were examined.

RESULTS

MDD is highly prevalent in patients with congestive heart failure. Moreover, the prevalence and severity of depression correlate with the degree of cardiac dysfunction and development of congestive heart failure. Depression increases the risk of congestive heart failure, particularly in those patients with coronary artery disease , and is associated with a poorer quality of life, increased use of health care resources, more frequent adverse clinical events and hospitalizations, and twice the risk of mortality.

CONCLUSIONS

At present, limited empirical data exist with regard to treatment of depression in the increasingly large population of patients with congestive heart failure. Evidence reveals that both psychotherapeutic treatment (eg, cognitive-behavioral therapy) and pharmacologic treatment (eg, use of the selective serotonin reuptake inhibitor sertraline) are safe and effective in reducing depression severity in patients with cardiovascular disease. Collaborative care programs featuring interventions that work to improve adherence to medical and psychiatric treatments improve both cardiovascular disease and depression outcomes. Depression rating scales such as the 9-item Patient Health Questionnaire should be used to monitor therapeutic efficacy.

Psychological responses and adherence to exercise in heart failure

PURPOSE

The purpose of this study was to describe psychological effects and exercise adherence during a multicomponent exercise training intervention.

METHODS

A sample of 42 patients with heart failure were randomized into an exercise (INV) group (n = 22) and an attention control (AC) group (n = 20). The exercise protocol included two 12-week phases, a structured phase and a self-managed phase. The psychological responses assessed were mood states and exercise self-efficacy. To meet the second purpose of the study, the exercise group was dichotomized based on the number of sessions completed to create two adherence subgroups.

FINDINGS

Results indicate self-efficacy improved for the INV group and was maintained during the self-management phase. The adherence subgroups demonstrated different patterns for weekly exercise. Depression and confusion scores improved for the high-adherence group in contrast to worsening for the low-adherence group.

CONCLUSIONS

Results suggest a need for further study of the psychological responses of exercise adherence for patients with heart failure.

CLINICAL RELEVANCE

The study indicates the importance of continuous assessment of exercise participation and longer term adherence support for patients with heart failure.

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.

Effect of psychosocial interventions on quality of life in patients with chronic heart failure: a meta-analysis of randomized controlled trials

BACKGROUND

Patients with chronic heart failure (CHF) usually experience poor quality of life (QoL). Psychosocial interventions tend to affect QoL in CHF. The aim of this study was to explore: 1) the effectiveness of psychosocial interventions on patients' QoL; 2) the magnitude of this effect; and 3) factors that appear to moderate the reported effect on QoL.

METHODS AND RESULTS

Meta-analysis of the data of 1,074 intervention patients and 1,106 control patients from 16 randomized controlled trials (RCTs) that reported QoL measures in treatment and control groups before and after a psychosocial intervention. Subgroup analyses were conducted between: 1) face-to-face versus telephone interventions; 2) interventions that included only patients versus those that included patients and their caregivers; and 3) interventions conducted by a physician and a nurse only, versus those conducted by a multidisciplinary team. Psychosocial interventions improved QoL of CHF patients (standardized mean difference 0.46, confidence interval [CI] 0.19-0.72; P < .001). Face-to-face interventions showed greater QoL improvement compared with telephone interventions (χ(2) = 5.73; df = 1; P < .02). Interventions that included caregivers did not appear to be significantly more effective (χ(2) = 1.12; df = 1; P > .29). A trend was found for multidisciplinary team approaches being more effective compared with nonmultidisciplinary approaches (χ(2) = 1.96; df = 1; P = .16).

CONCLUSIONS

A significant overall QoL improvement emerged after conducting psychosocial interventions with CHF patients. Interventions based on a face-to-face approach showed greater benefit for patients' QoL compared with telephone-based approaches. No significant advantage was found for interventions conducted by a multidisciplinary team compared with a physician and nurse approach, or for psychosocial interventions which included patients' caregivers compared with patient-only approaches.

Antidepressants do not improve event-free survival in patients with heart failure when depressive symptoms remain

OBJECTIVE

The purpose of this secondary data analysis was to compare event-free survival among four groups of patients with heart failure (HF) that were stratified by presence of depressive symptoms and antidepressants.

METHODS

We analyzed data from 209 outpatients (30.6% female, 62 ± 12 years, 54% NYHA Class III/IV) enrolled in a multicenter HF registry who had data on depressive symptoms, antidepressant use, and cardiac rehospitalization and death outcomes during 1 year follow up. Depressive symptoms were assessed using the Patient Health Questionnaire-9.

RESULTS

Depressive symptoms, not antidepressant therapy, predicted event-free survival (HR = 2.4, 95% CI = 1.2-4.6, p = .009). Depressed patients without antidepressants had 4.1 times higher risk of death and hospitalization than non-depressed patients on antidepressant (95% CI = 1.2-13.9, p = .022) after controlling for age, gender, NYHA class, body mass index, diabetes, medication of ACEI and beta-blockers.

CONCLUSION

Antidepressant use was not a predictor of event-free survival outcomes when patients still reported depressive symptoms. Ongoing assessment of patients on antidepressants is needed to assure adequate treatment.

Emotional coping is a better predictor of cardiac prognosis than depression and anxiety

OBJECTIVE

We compared, in a prospective study on patients with acute coronary syndrome, the predictive effect of a depression or anxiety diagnosis and of emotion-focused, problem-focused and dysfunctional coping strategies, as detected early after an acute event, on patients' left ventricular ejection fraction (LVEF), a reliable prognostic index of disease severity, at a three-month follow up.

METHODS

Ninety consecutive patients following an acute coronary syndrome event (83.3% men; mean age 56.9 ± 8.9 years) were included in the study. Demographic and clinical characteristics, presence of depression and anxiety disorders (MINI), and active use of emotion-focused, problem-focused and dysfunctional coping strategies (Brief Cope) were assessed at the time of enrolment. LVEF at a three-month follow up was used as the outcome measure.

RESULTS

The medical predictors of LVEF accounted for 10.6% of the variance of LVEF at follow up. Emotion-focused coping strategies significantly contributed for an additional 6.1%, while the presence of a depression and/or anxiety disorder was not a significant predictor of LVEF at follow up, nor were dysfunctional and problem-focused coping strategies.

CONCLUSION

Emotion-focused coping strategies at the time of the cardiac event were the only reliable psychological predictor of disease severity at a three-month follow up. These findings hint to the possibility that variables such as emotional coping may be a fruitful target for psychological treatments directed at cardiac patients in primary care settings.

Perceived social support predicted quality of life in patients with heart failure, but the effect is mediated by depressive symptoms

PURPOSE

Depressive symptoms and inadequate social support are well-known independent predictors of increased mortality and morbidity in heart failure (HF). However, it is unclear how depressive symptoms and social support interact to influence quality of life. Thus, the purpose of this study was to determine the nature of the relationships (direct, mediator, and moderator) among depressive symptoms, social support, and quality of life in patients with HF.

METHODS

We performed a secondary data analysis that included 362 patients with HF who completed the measures of depressive symptoms (the Beck Depression Inventory-II), perceived social support (the Multidimensional Scale of Perceived Social Support), and quality of life (the Minnesota Living with Heart Failure Questionnaire) instruments. The direct, mediator, and moderator effects of both depressive symptoms and social support on quality of life were tested using multiple regressions and 2 × 2 ANCOVA.

RESULTS

Less social support and greater depressive symptoms independently predicted poorer quality of life. The relationship between social support and quality of life was mediated by depressive symptoms. Neither social support nor depressive symptoms moderated quality of life.

CONCLUSION

Promotion of social support will improve quality of life only when depressive symptoms are also effectively managed.

WELL.ME - Wellbeing therapy based on real-time personalized mobile architecture, vs. cognitive therapy, to reduce psychological distress and promote healthy lifestyle in cardiovascular disease patients: study protocol for a randomized controlled trial

BACKGROUND

There is compelling evidence that psychological factors may have the same or even greater impact on the possibility of adverse events on cardiac diseases (CD) than other traditional clinical risk factors. Anxiety and depression are predictors of short- and long-term adverse outcomes, increased risk for higher rates of in-hospital complications, re-infarction, malignant arrhythmias, and mortality in CD patients. Despite researchers finding that cognitive behavior therapy (CBT) reduced depressive and anxiety symptoms, the fact that such results are maintained only in the short term and the lack of maintenance of the long-term affects the absence of changes in lifestyles, preventing the possibility of a wide generalization of results. Recently wellbeing therapy (WBT) has been proposed as a useful approach to improve healthy lifestyle behaviors and reduce psychological distress.

METHODS/DESIGN

The present randomized controlled study will test WBT, in comparison with CBT, as far as the reduction of symptoms of depression, anxiety and psychological distress, and the improvement of lifestyle behaviors and quality of life in cardiac patients are concerned. Moreover, innovations in communication technologies allow patients to be constantly followed in real life. Therefore WBT based on personalized mobile technology will allow the testing of its effectiveness in comparison with usual WBT.

DISCUSSION

The present study is a large outpatient study on the treatment of co-morbid depression, anxiety, and psychological distress in cardiac patients. The most important issues of this study are its randomized design, the focus on promotion of health-related behaviors, and the use of innovative technologies supporting patients' wellbeing in real life and in a continuous way. First results are expected in 2012.

Triangulating Clinically Meaningful Change in the Six-minute Walk Test in Individuals with Chronic Heart Failure: A Systematic Review

PURPOSE

The purpose of the present review was to use existing, published data to provide an estimate of the amount of change in six-minute walk test distance (Δ6MWT) that represents a clinically meaningful change in individuals with chronic heart failure (CHF).

METHODS

THE PRESENT REVIEW INCLUDED TWO SEPARATE LITERATURE SEARCHES OF THE CINAHL AND MEDLINE DATABASES FOR ARTICLES THAT: (1) reported the intraclass correlation coefficient (ICC) of the 6MWT in individuals with CHF, and (2) used the 6MWT along with either aerobic capacity or health-related quality of life (HRQL) as study endpoints in randomized controlled trials (RCTs) of exercise-based intervention for individuals with CHF. The ICCs were used to calculate the minimum detectable difference (MDD) at the 95% confidence interval for each included study. The Δ6MWT associated with aerobic capacity and HRQL within-group effect sizes for the intervention and control groups in each included RCT was analyzed using receiver operating characteristic (ROC) curves.

RESULTS

Thirteen articles reported the ICC for the 6MWT. The mean (standard deviation) MDD calculated based on these data was 43.1(16.8) m. Eighteen RCTs measured the 6MWT and either aerobic capacity and/or HRQL. A Δ6MWT of 40-45 m was associated with at least moderate aerobic capacity and HRQL effect sizes in the intervention groups. The Δ6MWT thresholds that discriminated between intervention and control groups using ROC curves revealed the following sensitivity/specificity for the respective thresholds: 19 m, 94.4/83.3%, 32 m, 83.3/94.4%, and 48 m 44.4/100% (AUC = .935, p = .009, CI(95%) .855, 1.015).

CONCLUSIONS

A Δ6MWT of approximately 45 m appears to exceed measurement error and be associated with significant changes in either aerobic capacity and/or HRQL.

A combined aerobic and resistance exercise program improves physical functional performance in patients with heart failure: a pilot study

BACKGROUND

Recent guidelines for exercise in patients with heart failure (HF) recommended aerobic and resistance exercise as being safe and effective; however, the clinical and functional significance of these combined training modalities has not been established. In this pilot study, combined aerobic and resistance training was hypothesized to improve physical function, muscle strength, and health-related quality of life (HRQOL) compared with an attention control wait list (ACWL).

METHODS

The 10-item Continuous Scale Physical Functional Performance Test (CS-PFP10), which simulates common household chores; muscle strength (handgrip and knee extension); and HRQOL (Kansas City Cardiomyopathy Questionnaire) were evaluated at baseline (T1) and at 12 weeks (T2). The home-based moderate-intensity walking and resistance training program was performed 5 days a week.

RESULTS

Twenty-four New York Heart Association class II to III HF patients (mean [SD] age, 60 [10] years; mean [SD] left ventricular ejection fraction, 25% [9%]) were randomized to a combined aerobic and resistance exercise program or to an ACWL group. Of the total group, 58% were New York Heart Association class III HF patients, 50% were white, and 50% were female. The CS-PFP10 total scores were significantly increased in the exercise group, from 45 (18) to 56 (16). The Kansas City Cardiomyopathy Questionnaire overall summary score was significantly improved (P < .001) at T2 in the exercise intervention group compared with the ACWL group.

CONCLUSIONS

Participants provided the home-based, combined aerobic and resistance exercise program had significantly improved physical function, muscle strength, symptom severity, and HRQOL compared with the ACWL group. The findings of this study must be interpreted cautiously owing to the limitations of a small sample, data collection from a single center, and differences between control and interventions groups at baseline. A combined aerobic and resistance exercise approach may improve physical function in stable HF patients, but further study in a larger, more diverse population is recommended. However, in this study, the CS-PFP10 instrument demonstrated its ability to identify functional health status in HF patients and thus warrants further testing in a larger sample for possible use in clinical practice.

Psychiatric disorders and cardiac anxiety in exercising and sedentary coronary artery disease patients: a case-control study

Regular physical exercise has been shown to favorably influence mood and anxiety; however, there are few studies regarding psychiatric aspects of physically active patients with coronary artery disease (CAD). The objective of the present study was to compare the prevalence of psychiatric disorders and cardiac anxiety in sedentary and exercising CAD patients. A total sample of 119 CAD patients (74 men) were enrolled in a case-control study. The subjects were interviewed to identify psychiatric disorders and responded to the Cardiac Anxiety Questionnaire. In the exercise group (N = 60), there was a lower prevalence (45 vs 81%; P < 0.001) of at least one psychiatric diagnosis, as well as multiple comorbidities, when compared to the sedentary group (N = 59). Considering the Cardiac Anxiety Questionnaire, sedentary patients presented higher scores compared to exercisers (mean ± SEM = 55.8 ± 1.9 vs 37.3 ± 1.6; P < 0.001). In a regression model, to be attending a medically supervised exercise program presented a relevant potential for a 35% reduction in cardiac anxiety. CAD patients regularly attending an exercise program presented less current psychiatric diagnoses and multiple mental-related comorbidities and lower scores of cardiac anxiety. These salutary mental effects add to the already known health benefits of exercise for CAD patients.

Exercise for depression

BACKGROUND

Depression is a common and important cause of morbidity and mortality worldwide. Depression is commonly treated with antidepressants and/or psychotherapy, but some people may prefer alternative approaches such as exercise. There are a number of theoretical reasons why exercise may improve depression. This is an update of an earlier review first published in 2009.

OBJECTIVES

To determine the effectiveness of exercise in the treatment of depression. Our secondary outcomes included drop-outs from exercise and control groups, costs, quality of life and adverse events.

SEARCH METHODS

We searched the Cochrane Depression, Anxiety and Neurosis (CCDAN) Review Group's Specialised Register (CCDANCTR), CENTRAL, MEDLINE, EMBASE, Sports Discus and PsycINFO for eligible studies (to February 2010). We also searched www.controlled-trials.com in November 2010. The CCDAN Group searched its Specialised Register in June 2011 and potentially eligible trials were listed as 'awaiting assessment'.

SELECTION CRITERIA

Randomised controlled trials in which exercise was compared to standard treatment, no treatment or a placebo treatment in adults (aged 18 and over) with depression, as defined by trial authors. We excluded trials of postnatal depression.

DATA COLLECTION AND ANALYSIS

For this update, two review authors extracted data on outcomes at the end of the trial. We used these data to calculate effect sizes for each trial using Hedges' g method and a standardised mean difference (SMD) for the overall pooled effect, using a random-effects model. Where trials used a number of different tools to assess depression, we included the main outcome measure only in the meta-analysis. We systematically extracted data on adverse effects and two authors performed the 'Risk of bias' assessments.

MAIN RESULTS

Thirty-two trials (1858 participants) fulfilled our inclusion criteria, of which 30 provided data for meta-analyses. Randomisation was adequately concealed in 11 studies, 12 used intention-to-treat analyses and nine used blinded outcome assessors. For the 28 trials (1101 participants) comparing exercise with no treatment or a control intervention, at post-treatment analysis the pooled SMD was -0.67 (95% confidence interval (CI) -0.90 to -0.43), indicating a moderate clinical effect. However, when we included only the four trials (326 participants) with adequate allocation concealment, intention-to-treat analysis and blinded outcome assessment, the pooled SMD was -0.31 (95% CI -0.63 to 0.01) indicating a small effect in favour of exercise. There was no difference in drop-outs between exercise and control groups. Pooled data from the seven trials (373 participants) that provided long-term follow-up data also found a small effect in favour of exercise (SMD -0.39, 95% CI -0.69 to -0.09). Of the six trials comparing exercise with cognitive behavioural therapy (152 participants), the effect of exercise was not significantly different from that of cognitive therapy. There were insufficient data to determine risks, costs and quality of life.Five potentially eligible studies identified by the search of the CCDAN Specialised Register in 2011 are listed as 'awaiting classification' and will be included in the next update of this review.

AUTHORS' CONCLUSIONS

Exercise seems to improve depressive symptoms in people with a diagnosis of depression when compared with no treatment or control intervention, however since analyses of methodologically robust trials show a much smaller effect in favour of exercise, some caution is required in interpreting these results.

Components of heart failure management in home care; a literature review

BACKGROUND

Patients with heart failure (HF) need long-term and complex care delivered by healthcare professionals in primary and secondary care. Although guidelines on optimal HF care exist, no specific description of components that are applied for optimal HF care at home exist. The objective of this review was to describe which components of HF (home) care are found in research studies addressing homecare interventions in the HF population.

METHODS

The Pubmed, Embase, Cinahl, and Cochrane databases were searched using HF-, homecare services-, and clinical trial-related search terms.

RESULTS

The literature search identified 703 potentially relevant publications, out of which 70 articles were included. All articles described interventions with two or more of the following components: multidisciplinary team, continuity of care and care plans, optimized treatment according to guidelines, educational and counselling of patients and caregivers, and increased accessibility to care. Most studies (n=65, 93%) tested interventions with three components or more and 20 studies (29%) used interventions including all five components.

CONCLUSIONS

There a several studies on HF care at home, testing interventions with a variety in number of components. Comparing the results to current standards, aspects such as collaboration between primary care and hospital care, titration of medication, and patient education can be improved.

Depressive symptom trajectory predicts 1-year health-related quality of life in patients with heart failure

BACKGROUND

One-third of patients with heart failure (HF) experience depressive symptoms that adversely affect health-related quality of life (HRQOL). We aimed to describe depressive symptom trajectory and determine whether a change in depressive symptoms predicts subsequent HRQOL.

METHODS AND RESULTS

The sample consisted of 256 inpatients and outpatients with HF. Depressive symptoms were measured at baseline and 3 or 6 months with the Patient Health Questionnaire (PHQ-9). The Minnesota Living with HF Questionnaire was used to assess HRQOL at baseline, 3 to 6 months, and 1 year. Based on baseline and 3- to 6-month PHQ-9 scores, patients were categorized as depressive symptom-free (64%), depressive symptoms improved (15%), depressive symptoms developed (6%), or persistent depressive symptoms (15%). The groups differed in 1-year HRQOL levels (F = 36, P < .001); patients who were depressive symptom-free or whose depressive symptoms improved had better 1-year HRQOL than patients with persistent depressive symptoms (Tukey honestly significant difference, P < .01). Change in depressive symptoms was the strongest predictor of 1-year HRQOL (standardized β = .42, P < .001), after controlling for functional status, demographics, and clinical variables.

CONCLUSIONS

We found the trajectory of depressive symptoms predicts future HRQOL. Research is needed to determine whether interventions targeting depressive symptoms improve HRQOL in patients with HF.

Evaluation of frailty in older adults with cardiovascular disease: incorporating physical performance measures

Rapid growth in the numbers of older adults with cardiovascular disease (CVD) is raising awareness and concern of the impact that common geriatric syndromes such as frailty may have on clinical outcomes, health-related quality of life, and rising economic burden associated with healthcare. Increasingly, frailty is recognized to be a highly prevalent and important risk factor that is associated with adverse cardiovascular outcomes. A limitation of previous studies in patients with CVD has been the lack of a consistent definition and measures to evaluate frailty. In this review, building upon the work of Fried and colleagues, a definition of frailty is provided that is applicable for evaluating frailty in older adults with CVD. Simple, well-established performance-based measures widely used in comprehensive geriatric assessment are recommended that can be readily implemented by nurses in most practice settings. The limited studies conducted in older adults with CVD have shown physical performance measures to be highly predictive of clinical outcomes. Implications for practice and areas for future research are described for the growing numbers of elderly cardiac patients who are frail frailty and at risk for disability.

Cardiac rehabilitation programs and health-related quality of life. State of the art

Cardiovascular disease is the main health problem in developed countries. Prevention is presented as the most effective and efficient primary care intervention, whereas cardiac rehabilitation programs are considered the most effective of secondary prevention interventions; however, these are underused. This literature review examines the effectiveness and the levels of evidence of cardiac rehabilitation programs, their components, their development and role in developed countries, applications in different fields of research and treatment, including their psychological aspects, and their application in heart failure as a paradigm of disease care under this type of intervention. It is completed by a review of the impact of such programs on measures of health-related quality of life, describing the instruments involved in studies in recent scientific literature.

Anxiety, panic disorder and coronary artery disease: issues concerning physical exercise and cognitive behavioral therapy

Psychological factors such as stress and depression have already been established as primary and secondary cardiovascular risk factors. More recently, the role of anxiety in increasing cardiac risk has also been studied. The underlying mechanisms of increased cardiac risk in panic disorder patients seem to reflect the direct and indirect effects of autonomic dysfunction, as well as behavioral risk factors associated with an unhealthy lifestyle. Implications of the comorbidity between panic and cardiovascular disease include higher morbidity, functional deficits, increased cardiovascular risk, and poor adherence to cardiac rehabilitation or exercise programs. This article probes the most recent evidence on the association between coronary artery disease, anxiety and panic disorder, and discusses the potential role of incorporating regular physical exercise and cognitive behavioral therapy in the treatment of this condition.

The Relationship Between Behavior Change Strategies, Physical Activity, and Fruit and Vegetable Intake Following a Cardiac Event

Objective: To assess expectations for recovery and use of behavior change strategies as predictors of subsequent diet and physical activity among adults recently hospitalized for a cardiac event. Design: Quasi-experimental design in which adults with recent cardiac event-related hospitalization completed surveys assessing health behaviors and attitudes immediately post-discharge and three months later. Results: Among those completing the study (n = 323), positive expectations about recovery and more frequent use of behavior change skills predicted greater physical activity and better nutrition at follow-up. In multivariate models, baseline health behavior was a significant predictor of physical activity and fruit and vegetable intake at follow-up (alpha = 0.05). Conclusions: Individuals participating in physical activity and eating a heart-healthy diet approximately three months after cardiac hospitalization possessed behavior change skills. Early intervention is critical as health behaviors occurring just days after hospitalization predicted future health behavior.

Depressive symptoms and poor social support have a synergistic effect on event-free survival in patients with heart failure

BACKGROUND

Depressive symptoms and poor social support are predictors of increased morbidity and mortality in patients with heart failure (HF). However, the combined contribution of depressive symptoms and social support event-free survival of patients with HF has not been examined.

OBJECTIVE

To compare event-free survival in 4 groups of patients with HF stratified by depressive symptoms and perceived social support (PSS).

METHOD

A total of 220 patients completed the Beck Depression Inventory-II and the Multidimensional Perceived Social Support Scale and were followed for up to 4 years to collect data on death and hospitalizations.

RESULTS

Depressive symptoms (hazard ratio = 1.73, P = .008) and PSS (hazard ratio = 1.51, P = .048) were independent predictors of event-free survival. Depressed patients with low PSS had 2.1 times higher risk of events than non-depressed patients with high PSS (P = .003).

CONCLUSION

Depressive symptoms and poor social support had a negative additive effect on event-free survival in patients with HF.

Developing a shortened measure of negative thinking for use in patients with heart failure

OBJECTIVE

Negative thinking is a target for treatment of depressive symptoms in patients with heart failure (HF). A brief instrument is needed to measure negative thinking in these patients. The study objective was to shorten the Crandell Cognitions Inventory (CCI) for use in patients with HF.

METHODS

Baseline data from outpatients with HF (N = 179, 30% were female, age 60 ± 13 years) were used to evaluate psychometrics of the CCI. Internal consistency reliability was measured with Cronbach's alpha construct validity with hypothesis testing. Principal components analysis was used in shortening. A separate sample of hospitalized patients with HF (N = 77, 49% were female, age 66 ± 11 years) was used to validate the shortened CCI (CCI-SF).

RESULTS

The CCI showed evidence of reliability and validity, but there was item redundancy in outpatients with HF. The 12-item CCI-SF showed good evidence of reliability and validity in inpatients with HF.

CONCLUSION

The results support the reliability and validity of the CCI-SF to measure negative thinking in hospitalized patients with HF.
