Improving the Effectiveness of Psychological Interventions for Depression and Anxiety in Cardiac Rehabilitation: PATHWAY-A Single-Blind, Parallel, Randomized, Controlled Trial of Group Metacognitive Therapy

Effectiveness of psychological interventions in reducing post-traumatic stress among post-myocardial infarction patients: a systematic review and meta-analysis

AIMS

Myocardial infarction (MI) can lead to post-traumatic stress disorder (PTSD) which frequently occurs with anxiety and depression, impairing daily functioning and increasing the risk of recurrent cardiovascular events. While psychological interventions have shown promise in reducing anxiety and depression, their effectiveness for PTSD in post-MI patients remains unexplored. This systematic review and meta-analysis aim to evaluate the effectiveness of psychological interventions on PTSD, anxiety, and depression in post-MI patients.

METHODS AND RESULTS

A comprehensive search of databases (Cochrane, CINAHL, PubMed, PsycINFO, Scopus, Embase, Web of Science, CNKI, Wanfang, CBM, ProQuest Dissertations and Theses Global, ClinicalTrials.gov) was conducted until June 2024, identifying randomized controlled trials and quasi-experimental studies assessing psychological interventions in post-MI patients. Study quality was evaluated using the Cochrane Risk of Bias and ROBINS-I tools. Post-traumatic stress disorder outcomes were pooled using meta-analysis in RevMan 5.4. Narrative synthesis was conducted where meta-analysis was not feasible. Nine studies involving 1065 participants were included. Psychological interventions significantly reduced PTSD symptoms {standardized mean difference (SMD) = -0.43 [95% confidence interval (CI): -0.70 to -0.16, P = 0.002]}, anxiety, and depression post-intervention. Subgroup analyses found that intervention components influenced effectiveness, with first-line treatments [eye movement desensitization and reprocessing (EMDR) and cognitive-behavioural therapy (CBT)] demonstrating a medium effect (SMD = -0.40; 95% CI: -0.74 to -0.07; P = 0.02). No significant subgroup differences were found based on the control condition or geographical location of studies.

CONCLUSION

Psychological interventions, particularly CBT and EMDR, were effective in alleviating PTSD, anxiety, and depression in post-MI patients. Future high-quality research is needed to identify active components and optimize these psychological interventions.

Depression, Anxiety, and Quality of Life in a Cardiac Rehabilitation Program Without Dedicated Mental Health Resources Post-Myocardial Infarction

Anxiety and depression are common after a myocardial infarction (MI), so psychological and psychiatric mental health (MH) interventions are recommended during Cardiac Rehabilitation Programs (CRP). We aim to evaluate anxiety and depression symptoms and quality of life in MI sufferers followed in a CRP without dedicated MH resources. We prospectively included 164 MI patients in our CRP without dedicated MH resources. Patient Health Questionnaire 2-item (PHQ-2) and Generalized Anxiety Disorder 2-item (GAD-2) questionnaires for depression and anxiety screening (altered if ≥3 points) and the 36-Item Short Form Survey Instrument (SF-36) to analyze four MH components and Mental Component Summary (MCS) were assessed at the beginning and after CRP. The mean age was 61.35 ± 10.76 years, and most patients were male (86.6%). A significant improvement in SF-36 mental components (from +5.94 ± 27.98 to +8.31 ± 25 points, p < 0.001) and SF-36-MCS (+1.85 ± 10.23 points, p = 0.02) was noted, as well as a reduction in depression and anxiety symptoms in PHQ-2 and GAD-2 (p < 0.001). However, 33 (20.1%) patients showed a positive screening for depression and/or anxiety at the end of the program. These patients were younger (56.6 ± 8.05 vs. 62.55 ± 11.05 years, p = 0.004) and showed significantly worse initial scores of SF-36 mental components, PHQ-2, and GAD-2 (p < 0.001). We conclude that a Phase 2 CRP without dedicated MH resources can achieve significant improvements in MH well-being after MI. However, one-fifth of the population had substantial depression and/or anxiety symptoms at the end of the program. This subset, characterized by worse initial MH scores, may benefit from specific MH interventions during CRP.

Psychological interventions for depression and anxiety in patients with coronary heart disease, heart failure or atrial fibrillation: Cochrane systematic review and meta-analysis

AIMS

Depression and anxiety occur frequently in individuals with cardiovascular disease and are associated with poor prognosis. This Cochrane systematic review and meta-analysis assessed the effectiveness of psychological interventions on psychological and clinical outcomes in adults with coronary heart disease (CHD), heart failure (HF) or atrial fibrillation (AF).

METHODS AND RESULTS

CENTRAL, MEDLINE, Embase, PsycINFO, and CINAHL databases were searched from January 2009 to July 2022 for randomized controlled trials of psychological interventions vs. controls in adults with CHD, HF, or AF. Twenty-one studies (n = 2591) were assessed using random-effects models. We found psychological interventions reduced depression [standardized mean difference (SMD) -0.36; 95% confidence interval (CI) -0.65 to -0.06; P = 0.02], anxiety (SMD -0.57; 95% CI -0.96 to -0.18; P = 0.004), and improved mental health-related quality of life (HRQoL) (SMD 0.63, 95% CI 0.01 to 1.26; P = 0.05) (follow-up 6-12 months), but not physical health-related quality of life, all-cause mortality or major adverse cardiovascular events compared with controls. High heterogeneity was present across meta-analyses. Meta-regression analysis showed that psychological interventions designed to target anxiety, were more effective than non-targeted interventions.

CONCLUSION

This review found that psychological interventions improved depression, anxiety and mental HRQoL, with those targeting anxiety to show most benefit. Given the statistical heterogeneity, the precise magnitude of effects remains uncertain. Increasing use of multifactorial psychological interventions shows promise for incorporating patient needs and preferences. Investigation of those at high risk of poor outcomes, comparison of intervention components and those with AF is warranted.

Cost-effectiveness of metacognitive therapy for cardiac rehabilitation participants with symptoms of anxiety and/or depression: analysis of a randomised controlled trial

OBJECTIVES

The burden of cardiovascular disease (CVD) is increasing. Cardiac rehabilitation (CR) is a complex intervention offered to patients with CVD, following a heart event, diagnosis or intervention, and it aims to reduce mortality and morbidity. The objective of this within-trial economic evaluation was to compare the cost-effectiveness of metacognitive therapy (MCT) plus usual care (UC) to UC, from a health and social care perspective in the UK.

METHODS

A multicentre, single-blind, randomised controlled trial (ISRCTN74643496) was conducted in the UK involving 332 patients with CR with elevated symptoms of anxiety and/or depression and compared group-based MCT with UC. The primary outcome of the cost-effectiveness analysis was quality-adjusted life-years (QALYs). The time horizon of the primary analysis was a 12-month follow-up. Missing data were imputed using multiple imputation. Uncertainty was explored by probabilistic bootstrapping. Sensitivity analyses tested the impact of the study design and assumptions on the incremental cost-effectiveness ratio.

RESULTS

In the primary cost-effectiveness analysis, MCT intervention was dominant, with a cost-saving (net cost -£219; 95% CI -£1446, £1007) and QALY gains (net QALY 0.015; 95% CI -0.015, 0.045). However, there is a high level of uncertainty in the estimates. At a threshold of £30 000 per QALY, MCT intervention of around 76% was likely to be cost-effective.

CONCLUSIONS

Results suggest that intervention may be cost-saving and health-increasing; however, findings are uncertain and subject to limitations. Further research should aim to reduce the uncertainty in the findings (eg, with larger sample sizes) and explore potential longer-term economic benefits associated with MCT in this setting.

Cardiac rehabilitation: the gateway for secondary prevention

Cardiac rehabilitation (CR) is a multidisciplinary supervised programme which typically consists of tailored exercise and education on lifestyle management and risk factor modification in cardiac patients. Participation in CR reduces morbidity and mortality, while improving quality of life following major cardiovascular events. Despite the benefits of CR, it is underutilised, generally in the 20%-30% range for eligible patients. Participation and adherence rates are particularly suboptimal in vulnerable populations, such as those of lower socioeconomic status and women. Interventions such as automated referral to CR or hybrid/virtual programmes can increase enrolment to CR. This review summarises the components of CR and provides recommendations for providers regarding participation and adherence. To better engage a larger proportion of CR-eligible patients, CR programmes may need to expand or adjust ways to deliver secondary prevention.

Protocol for an implementation study of group metacognitive therapy for anxiety and depression in NHS cardiac rehabilitation services in England (PATHWAY-Beacons)

Background

Cardiac rehabilitation (CR) services aim to improve heart disease patients' health and quality of life and reduce the risk of further cardiac events. Depression and anxiety are common among CR patients but psychological treatments have usually had small effects. In contrast, the recent NIHR-funded PATHWAY trial found that group Metacognitive Therapy (MCT) was associated with improvements in anxiety and depression when added to CR and was more effective than usual CR alone. The next stage is to test implementation of MCT within the National Health Service through the creation of a network of CR beacon sites. The study will test the quality of data capture following addition of a new MCT data-field to the national audit of cardiac rehabilitation (NACR), examine level of adoption at sites, examine mental health outcomes benchmarked against usual CR and the PATHWAY data, examine the enablers and barriers to implementation and the expected resource requirements. The study has been registered: NCT05956912 (13th July, 2023).

Methods

Beacon sites will be recruited as preliminary adopters of group MCT from NHS CR services in England. A national invitation for expressions of interest from CR services will be issued and those meeting eligibility criteria will be considered for inclusion. Two staff at each site will receive training in MCT, and mixed-methods will be used to address questions concerning the quality of patient data recorded, level of adoption at sites, the characteristics of patients attending MCT, the impact of adding MCT to CR on mental health outcomes, and patient, healthcare staff and commissioner views of barriers/enablers to implementation. Exploration of implementation will be informed by Normalisation Process Theory.

Discussion

The study will support development of an NHS roll-out strategy, assess the mental health outcomes associated with MCT, examine treatment fidelity in real-world settings, and evaluate revised data collection structures that can be used to assess the impact of national-level implementation.

Qualitative analysis of emotional distress in burns, plastic and reconstructive surgery patients from the perspectives of cognitive and metacognitive models

Introduction

Burns and other injuries requiring plastic and/or reconstructive surgery (BPRS) are lifechanging, often unexpected, and increase the risk of psychiatric morbidity. There are no published studies we are aware of that explores the applicability of psychological models to BPRS patients. Cognitive behavioural therapy (CBT) is the benchmark treatment in mental health but may be less effective in physical health settings. Metacognitive therapy (MCT)can be more effective than CBT in mental health settings and shows promise in reducing anxiety and depression symptoms in people with cancer and cardiac disease. The present study explored the psychological experiences (feelings, thoughts, and coping strategies) of BPRS patients, and whether the concepts underpinning cognitive and metacognitive models can be elicited from these accounts.

Method

Semi structured interviews were conducted with 11 patients recruited from a BPRS psychology service. Data was analysed using Thematic Analysis. Patients described a range of emotions including low mood, anxiety, anger, guilt, loss, and negative thinking.

Results

From the perspective of the cognitive model, there were examples of each of 10 pre-specified distorted thinking types (cognitive distortions), and patient talk seemed to fit problem-specific cognitive models. From the perspective of the metacognitive model, all patients described the "cognitive attentional syndrome," i.e., how they engaged in repetitive negative thinking (worry, rumination) and thought-focused regulation strategies. Patient talk also demonstrated both positive and negative metacognitive beliefs.

Conclusion

The implications of applying the findings from each model to clinical practice are discussed. The metacognitive model may offer benefits in clinical practice that should be investigated further.

Gender differences in cardiac rehabilitation participation and outcomes: an 18-year retrospective study in Iran

BACKGROUND

Cardiac rehabilitation (CR) is crucial for addressing cardiovascular diseases globally, with a specific emphasis on gender differences. Despite its demonstrated benefits for women, there's limited acceptance globally, especially in low- and middle-income countries. The program aims to optimize risk factors and improve overall patient well-being.

METHODS

A cohort study was performed on those who were candidates for CR programs during 2001-2019. Assessments were performed within one week before and one week after the 8-week CR program. Age, sex, smoking status, clinical data, resting systolic and diastolic blood pressure (SBP and DBP, respectively), echocardiography and laboratory data were obtained. Functional capacity was evaluated using the international physical activity questionnaire, and a treadmill exercise test. Anxiety, depression, general quality of life (QoL), and health-related QoL were selected for psychological status. Then statistical analysis was performed on data.

RESULT

In this study, the number of male patients was 1526 (73.69%). The average age of patients in the female group was higher than that of males (58.66 ± 9.08 vs. 56.18 ± 9.94), according to the crude model results, the changes in emotional, social and physical scores were significant (P-value:0.028, 0.018, 0.030), as well as the differences in Mets and smoking were significant (P-value for both < 0.001) in the adjusted model, the emotional variables and Mets changes were significant in two groups, so that the emotional score in the female group was higher than that of the male group, and the female Mets score was significantly lower than that of the male group.

CONCLUSION

The CR program can improve cardiovascular outcomes, but the greatest impact was on the quality of life, patient METs and smoking behavers. Also the number of female participants in the CR program was less than the number of males.

Cardiac Rehabilitation practitioners' views on patients' psychological needs: a qualitative study

Background

Psychological difficulties are prevalent in patients undergoing Cardiac Rehabilitation (CR). Recent guidelines recommend that practitioners inquire and address patients' psychological concerns during CR. Therefore, Study One aimed to explore practitioners' understanding of patients' psychological needs, their confidence in supporting those needs, and their views on whether current CR meets patients' needs. Study Two aimed to validate Study Ones' findings among a wider sample of CR practitioners.

Methods

This study consisted of two interrelated qualitative interviews. Study One utilised qualitative interview data from the PATHWAY trial (REC Reference:15/NW/0163), while Study Two utilised new interview data collected as part of the PATHWAY Beacons study (REC Reference: 22/HRA/2220). In Study One semi-structured interviews with six CR practitioners were analysed using thematic analysis. In Study Two, 11 CR practitioners across England were interviewed using member-checking principles. Transcripts were coded systematically using the codes developed in Study One and, through constant comparative analysis.

Results

Four main themes were identified: staff's awareness of mental health problems, CR patients' needs, staff's self-efficacy to support patients' psychological needs, and current psychological provision in CR. The main themes and 11 subthemes were transferable to a wider range of CR practitioners, thereby indicating the trustworthiness of the findings.

Conclusion

Practitioners described that patients experience a range of psychological concerns, including adjustment difficulties, anxiety, and cardiac and noncardiac worries. Most practitioners normalise patient concerns and offer relaxation techniques. However, practitioners have noted that patients often have complex psychological needs, but practitioners' confidence in discussing and supporting psychological concerns varies. Practitioners expressed the need for training to support patients' psychological needs.

Stress and cardiovascular disease: an update

Psychological stress is generally accepted to be associated with an increased risk of cardiovascular disease (CVD), but results have varied in terms of how stress is measured and the strength of the association. Additionally, the mechanisms and potential causal links have remained speculative despite decades of research. The physiological responses to stress are well characterized, but their contribution to the development and progression of CVD has received little attention in empirical studies. Evidence suggests that physiological responses to stress have a fundamental role in the risk of CVD and that haemodynamic, vascular and immune perturbations triggered by stress are especially implicated. Stress response physiology is regulated by the corticolimbic regions of the brain, which have outputs to the autonomic nervous system. Variation in these regulatory pathways might explain interindividual differences in vulnerability to stress. Dynamic perturbations in autonomic, immune and vascular functions are probably also implicated as CVD risk mechanisms of chronic, recurring and cumulative stressful exposures, but more data are needed from prospective studies and from assessments in real-life situations. Psychological assessment remains insufficiently recognized in clinical care and prevention. Although stress-reduction interventions might mitigate perceived stress levels and potentially reduce cardiovascular risk, more data from randomized trials are needed.

The Role of Psychosocial Stress on Cardiovascular Disease in Women: JACC State-of-the-Art Review

Psychosocial stress can affect cardiovascular health through multiple pathways. Certain stressors, such as socioeconomic disadvantage, childhood adversity, intimate partner violence, and caregiving stress, are especially common among women. The consequences of stress begin at a young age and persist throughout the life course. This is especially true for women, among whom the burden of negative psychosocial experiences tends to be larger in young age and midlife. Menarche, pregnancy, and menopause can further exacerbate stress in vulnerable women. Not only is psychosocial adversity prevalent in women, but it could have more pronounced consequences for cardiovascular risk among women than among men. These differential effects could reside in sex differences in responses to stress, combined with women's propensity toward vasomotor reactivity, microvascular dysfunction, and inflammation. The bulk of evidence suggests that targeting stress could be an important strategy for cardiovascular risk reduction in women.

A comparative analysis of open heart surgery and minimally invasive cardiac surgery in exercise-based cardiac rehabilitation

BACKGROUND

Historically, the majority of patients admitted to inpatient exercise-based cardiac rehabilitation (EBCR) have undergone open heart surgery (OHS). However, with advances in minimally invasive cardiac surgery (MICS), these patient groups are also increasingly referred for inpatient EBCR. Herein, we aimed to compare the progress of these groups during rehabilitation.

METHODS

In this prospective, nonrandomized study, 403 inpatient EBCR patients were recruited from December 2022 until September 2023 and stratified into two groups: OHS, and MICS. Participants completed a 3-4-week certified EBCR program. The primary endpoint was defined as a change in the 6-minute walk test (6MWT). Moreover, a comprehensive panel of quality-of-life (QoL) assessments were performed at admission and discharge.

RESULTS

At baseline, patients with OHS were older (66 years [IQR 59 - 72]), more often male (83%), and underwent emergency/urgent procedures more often (20%) than patients with MICS. Furthermore, patients with MICS showed a better 6MWT at admission (426 meters [IQR 336 - 483]) compared to patients with OHS (381 meters [IQR 299 - 453]). While all patients were able to increase the distance in the 6MWT, regression analyses in fully adjusted models showed no difference in improvements between the two groups (β -5, 95% CI, -26 - 14, p = 0.58). Moreover, during EBCR, we observed significant improvements in all QoL measures in all groups.

CONCLUSIONS

In this study, improvements in fitness, as assessed by the 6WMT were observed in all groups. Furthermore, multiple QoL measures improved equally across all groups. These encouraging results emphasize the importance of EBCR.

The psychological well-being index and quality of life after a cardiac rehabilitation program based on aerobic training and psychosocial support

BACKGROUND

This study aimed to investigate the physical and psychological benefits of an alternative cardiac rehabilitation program based on therapeutic groups during physical exercise sessions and to compare the results with those of a conventional cardiac rehabilitation program.

METHOD

The sample included 112 patients from the cardiac rehabilitation unit of a medical center, 91.1 % of whom were male. The control group consisted of 47 subjects, with a mean age of 57.89 ± 12.30 and the experimental group consisted of 65 subjects, with a mean age of M = 58.38 ± 9.86. Quality of life, psychological well-being, health-related quality of life, body mass index, blood pressure, abdominal circumference and resting heart rate were measured before starting and at the end of the cardiac rehabilitation program.

RESULTS

The experimental group improved significantly more than the control group in body mass index, systolic and diastolic blood pressure, abdominal circumference, and resting heart rate (p value < 0.005). In addition, the experimental group had significantly greater improvements in quality of life, psychological well-being, and health-related quality of life than the control group (p-value < 0.001).

CONCLUSIONS

A cardiac rehabilitation program based on simultaneous aerobic training and psychosocial support improved the physical function, health-related quality of life and well-being.

Effect of metacognitive therapy on depression in patients with chronic disease: a protocol for a systematic review and meta-analysis

BACKGROUND

Chronic diseases have a high prevalence worldwide, and patients with chronic diseases often suffer from depression, leading to a poor prognosis and a low quality of life. Metacognitive therapy is a transdiagnostic psychotherapy intervention focused on thinking patterns, with the advantages of reliable implementation effect, short intervention period and low cost. It can help patients change negative metacognition, alleviate depression symptoms, and has a higher implementation value compared with other cognitive interventions. Therefore, metacognitive therapy may be an effective way to improve the mental health of patients with chronic diseases.

METHODS AND ANALYSIS

Psychological interventions for depression and anxiety in patients with coronary heart disease, heart failure or atrial fibrillation

BACKGROUND

Depression and anxiety occur frequently (with reported prevalence rates of around 40%) in individuals with coronary heart disease (CHD), heart failure (HF) or atrial fibrillation (AF) and are associated with a poor prognosis, such as decreased health-related quality of life (HRQoL), and increased morbidity and mortality. Psychological interventions are developed and delivered by psychologists or specifically trained healthcare workers and commonly include cognitive behavioural therapies and mindfulness-based stress reduction. They have been shown to reduce depression and anxiety in the general population, though the exact mechanism of action is not well understood. Further, their effects on psychological and clinical outcomes in patients with CHD, HF or AF are unclear.

OBJECTIVES

To assess the effects of psychological interventions (alone, or with cardiac rehabilitation or pharmacotherapy, or both) in adults who have a diagnosis of CHD, HF or AF, compared to no psychological intervention, on psychological and clinical outcomes.

SEARCH METHODS

We searched the CENTRAL, MEDLINE, Embase, PsycINFO and CINAHL databases from 2009 to July 2022. We also searched three clinical trials registers in September 2020, and checked the reference lists of included studies. No language restrictions were applied.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) comparing psychological interventions with no psychological intervention for a minimum of six months follow-up in adults aged over 18 years with a clinical diagnosis of CHD, HF or AF, with or without depression or anxiety. Studies had to report on either depression or anxiety or both.

DATA COLLECTION AND ANALYSIS

We used standard Cochrane methods. Our primary outcomes were depression and anxiety, and our secondary outcomes of interest were HRQoL mental and physical components, all-cause mortality and major adverse cardiovascular events (MACE). We used GRADE to assess the certainty of evidence for each outcome.

MAIN RESULTS

Twenty-one studies (2591 participants) met our inclusion criteria. Sixteen studies included people with CHD, five with HF and none with AF. Study sample sizes ranged from 29 to 430. Twenty and 17 studies reported the primary outcomes of depression and anxiety, respectively. Despite the high heterogeneity and variation, we decided to pool the studies using a random-effects model, recognising that the model does not eliminate heterogeneity and findings should be interpreted cautiously. We found that psychological interventions probably have a moderate effect on reducing depression (standardised mean difference (SMD) -0.36, 95% confidence interval (CI) -0.65 to -0.06; 20 studies, 2531 participants; moderate-certainty evidence) and anxiety (SMD -0.57, 95% CI -0.96 to -0.18; 17 studies, 2235 participants; moderate-certainty evidence), compared to no psychological intervention. Psychological interventions may have little to no effect on HRQoL physical component summary scores (PCS) (SMD 0.48, 95% CI -0.02 to 0.98; 12 studies, 1454 participants; low-certainty evidence), but may have a moderate effect on improving HRQoL mental component summary scores (MCS) (SMD 0.63, 95% CI 0.01 to 1.26; 12 studies, 1454 participants; low-certainty evidence), compared to no psychological intervention. Psychological interventions probably have little to no effect on all-cause mortality (risk ratio (RR) 0.81, 95% CI 0.39 to 1.69; 3 studies, 615 participants; moderate-certainty evidence) and may have little to no effect on MACE (RR 1.22, 95% CI 0.77 to 1.92; 4 studies, 450 participants; low-certainty evidence), compared to no psychological intervention.

AUTHORS' CONCLUSIONS

Current evidence suggests that psychological interventions for depression and anxiety probably result in a moderate reduction in depression and anxiety and may result in a moderate improvement in HRQoL MCS, compared to no intervention. However, they may have little to no effect on HRQoL PCS and MACE, and probably do not reduce mortality (all-cause) in adults who have a diagnosis of CHD or HF, compared with no psychological intervention. There was moderate to substantial heterogeneity identified across studies. Thus, evidence of treatment effects on these outcomes warrants careful interpretation. As there were no studies of psychological interventions for patients with AF included in our review, this is a gap that needs to be addressed in future studies, particularly in view of the rapid growth of research on management of AF. Studies investigating cost-effectiveness, return to work and cardiovascular morbidity (revascularisation) are also needed to better understand the benefits of psychological interventions in populations with heart disease.

Cardiac Rehabilitation During the COVID-19 Pandemic and the Potential for Digital Technology to Support Physical Activity Maintenance: Qualitative Study

BACKGROUND

Social distancing from the COVID-19 pandemic may have decreased engagement in cardiac rehabilitation (CR) and may have had possible consequences on post-CR exercise maintenance. The increased use of technology as an adaptation may benefit post-CR participants via wearables and social media. Thus, we sought to explore the possible relationships of both the pandemic and technology on post-CR exercise maintenance.

OBJECTIVE

This study aimed to (1) understand CR participation during the COVID-19 pandemic, (2) identify perceived barriers and facilitators to physical activity after CR completion, and (3) assess willingness to use technology and social media to support physical activity needs among older adults with cardiovascular disease.

METHODS

We recruited participants aged 55 years and older in 3 different CR programs offered at both public and private hospitals in Northern California. We conducted individual interviews on CR experiences, physical activity, and potential for using technology. We used thematic analysis to synthesize the data.

RESULTS

In total, 22 participants (n=9, 41% female participants; mean age 73, SD 8 years) completed in-depth interviews. Themes from participants' feedback included the following: (1) anxiety and frustration about the wait for CR caused by COVID-19 conditions, (2) positive and safe participant experience once in CR during the pandemic, (3) greater attention needed to patients after completion of CR, (4) notable demand for technology during the pandemic and after completion of CR, and (5) social media networking during the CR program considered valuable if training is provided.

CONCLUSIONS

Individuals who completed CR identified shared concerns about continuing physical activity despite having positive experiences during the CR program. There were significant challenges during the pandemic and heightened concerns for safety and health. The idea of providing support by leveraging digital technology (wearable devices and social media for social support) resonated as a potential solution to help bridge the gap from CR to more independent physical activity. More attention is needed to help individuals experience a tailored and safe transition to home to maintain physical activity among those who complete CR.

The Role of Metacognition in the Prediction of Depressive and Anxiety Symptoms in Chronically Ill Patients

INTRODUCTION

Cancer, diabetes, and heart diseases are frequent causes of depression and anxiety. The study explored the metacognitive beliefs manifested by chronically ill patients and the presence of depressive or anxiety symptoms and the predictive role of metacognition in both.

METHODS

A total of 254 chronically ill patients participated in the study. The Metacognitive Questionnaire was used to measure the patients' metacognitive beliefs, whereas the Hospital Anxiety and Depression Scale was applied to evaluate their psychopathological symptoms. A correlation analysis was performed to explore the relationships between metacognition and psychopathological symptoms. Regression analyses were conducted to examine the predictive role of metacognition in anxiety and depression.

RESULTS

The Negative Beliefs about Uncontrollability and Danger scale correlated with both anxiety and depression scales, and the Cognitive Confidence scale correlated with the depression scale. Linear regression analyses indicated that metacognitive beliefs were responsible for 32.2% of the variance of anxiety symptoms among all the chronically ill. Metacognitive beliefs accounted for 48.8% of the variance in anxiety symptoms and 36.6% in depressive symptoms among diabetes patients.

CONCLUSIONS

There are specific correlations between psychopathological symptoms and metacognition among chronically ill patients. Metacognitions have a moderate role in developing and sustaining anxiety and depressive symptoms.

Cardiac rehabilitation for children and young people (CardioActive): protocol for a single-blind randomised feasibility and acceptability study of a centre-based cardiac rehabilitation programme versus usual care in 11-16 years with heart conditions

BACKGROUND

Congenital heart conditions are among the most common non-communicable diseases in children and young people (CYP), affecting 13.9 million CYP globally. While survival rates are increasing, support for young people adjusting to life with a heart condition is lacking. Furthermore, one in three CYP with heart conditions also experiences anxiety, depression or adjustment disorder, for which little support is offered. While adults are offered cardiac rehabilitation (CR) to support their mental and physical health, this is not offered for CYP.One way to overcome this is to evaluate a CR programme comprising exercise with mental health support (CardioActive; CA) for CYP with heart conditions. The exercise and mental health components are informed by the metacognitive model, which has been shown to be effective in treating anxiety and depression in CYP and associated with improving psychological outcomes in adult CR.

METHOD AND ANALYSIS

The study is a single-blind parallel randomised feasibility trial comparing a CR programme (CA) plus usual care against usual care alone with 100 CYP (50 per arm) aged 11-16 diagnosed with a heart condition. CA will include six group exercise, lifestyle and mental health modules. Usual care consists of routine outpatient management. Participants will be assessed at three time points: baseline, 3-month (post-treatment) and 6-month follow-up. Primary outcomes are feasibility and acceptability (ie, referral rates, recruitment and retention rates, attendance at the intervention, rate of return and level of completion of follow-up data). Coprimary symptom outcomes (Strength and Difficulties Questionnaire and Paediatric Quality of Life) and a range of secondary outcomes will be administered at each time point. A nested qualitative study will investigate CYP, parents and healthcare staff views of CR and its components, and staff's experience of delivering CA. Preliminary health economic data will be collected to inform future cost-effectiveness analyses. Descriptive data on study processes and clinical outcomes will be reported. Data analysis will follow intention to treat. Qualitative data will be analysed using thematic analysis and the theoretical framework of acceptability.

ETHICS AND DISSEMINATION

Ethical approval was granted on 14 February 2023 by the Greater Manchester East Research Ethics Committee (22/NW/0367). The results will be disseminated through peer-reviewed journals, conference presentations and local dissemination.

Psychological Distress and the Risk of Adverse Cardiovascular Outcomes in Patients With Coronary Heart Disease

BACKGROUND

Psychological distress is a recognized risk factor in patients with coronary heart disease (CHD), but its clinical significance is unclear.

OBJECTIVES

The purpose of this study was to determine if an index of psychological distress is independently associated with adverse outcomes and significantly contributes to risk prediction.

METHODS

Pooled analysis of 2 prospective cohort studies of patients with stable CHD (N = 891). A psychological distress score was constructed using measures of depression, anxiety, anger, perceived stress, and post-traumatic stress disorder, measured at baseline. The study endpoint included cardiovascular death or first or recurrent nonfatal myocardial infarction or hospitalization for heart failure at 5.9 years.

RESULTS

In both cohorts, first and recurrent events occurred more often among those in the highest tertile of distress score than those in the lowest tertile. After combining the 2 cohorts, compared with the lowest tertile, the hazards ratio for having a distress score in the highest tertile was 2.27 (95% CI: 1.69-3.06), and for the middle tertile, it was 1.52 (95% CI: 1.10-2.08). Adjustment for demographics and clinical risk factors only slightly weakened the associations. When the distress score was added to a traditional clinical risk model, C-statistic, net reclassification index, and integrative discrimination index all significantly improved.

CONCLUSIONS

Among patients with CHD, a composite measure of psychological distress was significantly associated with an increased risk of adverse events and significantly improved risk prediction.

Experience sampling methodology study of anxiety and depression in adolescents with epilepsy: The role of metacognitive beliefs and perseverative thinking

Emotional distress is common in young people with epilepsy (YPwE). According to the Self-Regulatory Executive Function (S-REF) model, maladaptive metacognitive beliefs and perseverative thinking are fundamental in the development and maintenance of emotional distress. As emotional distress and perseverative thinking can highly fluctuate over short intervals in YPwE, it is important to account for this variability when testing the utility of psychological models. Experience sampling methodology (ESM) was therefore used to explore the momentary relationship between metacognitive beliefs, perseverative thinking, and emotional distress in YPwE. Eighteen participants diagnosed with epilepsy (aged 12-17 years) completed the 10-day ESM period. Participants were prompted to complete the ESM assessment five times daily. The ESM assessment assessed participant's momentary levels of metacognitive beliefs, perseverative thinking (i.e., worry and rumination), and emotional distress (i.e., anxiety and depression). A series of multilevel regression analyses indicated that metacognitive beliefs were significantly positively associated with worry, rumination, anxiety and depression. After controlling for worry and rumination, respectively, metacognitive beliefs did not account for additional variance in anxiety or depression. Findings provide preliminary support for the utility of the S-REF model for emotional distress in YPwE. Metacognitive therapy, which is underpinned by the S-REF model, may be an appropriate intervention for emotional distress in YPwE. Future studies should assess the mediational relationship between metacognitive beliefs, perseverative thinking, and emotional distress using time-lagged models.

Metacognitions in patients with chronic obstructive pulmonary disease: a psychometric study of the metacognitions questionnaire-30

The metacognitions questionnaire-30 (MCQ-30) was developed for the assessment of metacognitive beliefs and processes that are central components of the metacognitive model of emotional disorders. Anxiety and depression commonly occur in patients with chronic obstructive pulmonary disease (COPD). Testing such a model for anxiety and depression in patients with COPD is warranted. However, the psychometric properties of the MCQ-30 in COPD patients are unknown. Therefore, in this study we aimed to examine these properties in COPD patients. The MCQ-30 was administered to 203 COPD patients referred to a rehabilitation unit in respiratory medicine. Confirmatory factor analysis (CFA) was used to test the five-factor as well as the bi-factor models of MCQ-30. Exploratory factor analyses were also performed. Both models did not meet the criteria for an acceptable fit on Comparative Fit Index (CFI) of 0.810 and 0.858 vs. criterion of ≥0.9, but the Root Mean Square Error of Approximation (RMSEA) criterion ≤0.08 was acceptable for both models with RMSEA = 0.074 and 0.066, respectively. The factors were mostly moderately correlated (0.41-0.58) with acceptable reliability coefficients (0.73-0.87). The exploratory factor analysis identified three of the five factors originally described in the five-factor model of the MCQ-30. These data show that the factor structure of the MCQ-30 appears to differ from that of the original instrument in COPD patients and further studies are needed to confirm its validity and reliability in this patient group.

Psychological interventions for depression in adolescent and adult congenital heart disease

BACKGROUND

Despite improvements in medical care, the quality of life of adults and adolescents with congenital heart disease remains strongly affected by their condition, often leading to depression. Psychotherapy, cognitive behavioural therapy, and other talking therapies may be effective in treating depression in both adults and young adults with congenital heart disease. The aim of this review was to assess the effects of treatments, such as psychotherapy, cognitive behavioural therapies, and talking therapies for treating depression in this population.

OBJECTIVES

To evaluate the effects (both harms and benefits) of psychological interventions for reducing symptoms of depression in adolescents (aged 10 to 17 years) and adults with congenital heart disease. Psychological interventions include cognitive behavioural therapy, psychotherapy, or 'talking/counselling' therapy for depression.

SEARCH METHODS

We updated searches from the 2013 Cochrane Review by searching CENTRAL, four other databases, and Conference Proceedings Citation Index to 7 March 2023, and two clinical trial registers to February 2021. We applied no language restrictions.

SELECTION CRITERIA

Randomised controlled trials (RCTs) comparing psychological interventions to no intervention in the congenital heart disease population, aged 10 years and older, with depression.

DATA COLLECTION AND ANALYSIS

Two review authors independently screened titles and abstracts, and independently assessed full-text reports for inclusion. Further information was sought from the authors if needed. Data were extracted in duplicate. We used standard Cochrane methods. Our primary outcome was a change in depression. Our secondary outcomes were: acceptability of treatment, quality of life, hospital re-admission, non-fatal cardiovascular events, cardiovascular behavioural risk factor, health economics, cardiovascular mortality, all-cause mortality. We used GRADE to assess the certainty of evidence for our primary outcome only.

MAIN RESULTS

We identified three new RCTs (480 participants). Participants were adults with congenital heart disease. Included studies varied in intervention length (90 minutes to 3 months) and follow-up (3 to 12 months), with depression assessed post-intervention and at follow-up. Risk of bias assessment identified an overall low risk of bias for the main outcome of depression. Psychological interventions (talking/counselling therapy) may reduce depression more than usual care at both three-month (mean difference (MD) -1.07, 95% confidence interval (CI) -1.84 to -0.30; P = 0.006; I2 = 0%; 2 RCTs, 156 participants; low-certainty evidence), and 12-month follow-up (MD -1.02, 95% CI -1.92 to -0.13; P = 0.02; I2 = 0%; 2 RCTs, 287 participants; low-certainty evidence). There was insufficient evidence to draw conclusions about the impact of psychological interventions on quality of life. None of the included studies reported on our other outcomes of interest. Due to the low number of studies included, we did not undertake any subgroup analyses. One study awaits classification.

AUTHORS' CONCLUSIONS

Psychological interventions may reduce depression in adults with congenital heart disease compared to usual care. However, the certainty of the evidence is low. Further research is needed to establish the role of psychological interventions in this population, defining the optimal duration, method of administration, and number of sessions required to obtain the greatest benefit.

Attention training technique delivered in groups as treatment for anxiety and depression in patients with coronary heart disease: study protocol for a waiting-list randomized controlled trial

Introduction

Clinically significant symptoms of depression and anxiety in coronary heart disease (CHD) patients are common and associated with adverse outcomes. Psychological treatments have shown limited effectiveness and more effective treatments have been requested. Attention training technique (ATT), a component of metacognitive therapy, can potentially be effective as a stand-alone treatment for anxiety and depression. In an open study, ATT delivered face-to-face in a group format was feasible and potentially effective for improving depression and anxiety symptoms in CHD patients. The next progressive step is to test the effectiveness of ATT in a randomized controlled trial. This paper describes the methodology of this trial.

Methods

ATT-CHD is a randomized wait-list (WL) controlled study. Eligible CHD patients from two hospitals with Hospital Anxiety and Depression Scale (HADS)-Anxiety and/or HADS-Depression subscales scores ≥8 will be randomized into ATT (n = 32) or WL control (n = 32). After 6-8 weeks, WL patients will be allocated to ATT. Participants will be evaluated pre-, mid- and post-treatment, and at 6-months follow-up using changes in HADS as primary outcome. Secondary outcomes will be changes in psychiatric disorders, rumination, worry, type D-personality, metacognitions, insomnia, quality of life, and C-Reactive protein (CRP).

Discussion

To our knowledge, this will be the first WL-controlled randomized study testing the effectiveness of group-based ATT as treatment of symptoms of anxiety and depression in CHD patients. It will also explore correlations between changes in psychological distress and CRP. A qualitative analysis will reveal patients' experience with ATT including processes that may facilitate or serve as barriers to effectiveness. Recruitment into the study commenced in December 2022.

Ethics and dissemination

The Regional Committees for Medical and Health Research Ethics (REK), Norway has granted approval for the study (ID 52002). The trial results will be published in peer-reviewed journals. According to Norwegian legislation, the Norwegian Data Protection Authority, and the Committee of Ethics, we are not allowed to share original study data publicly.

Clinical trial registration

ClinicalTrials.gov, identifier NCT05621408 pre-inclusion. There were no significant changes of methods or outcomes after study start.

Do metacognitive beliefs predict rumination and psychological distress independently of illness representations in adults with diabetes mellitus? A prospective mediation study

OBJECTIVE

Adults with Diabetes Mellitus (DM) experience high levels of depression and anxiety that are not always effectively ameliorated by current therapeutic approaches. The Self-Regulatory Executive Function (S-REF) model, which underpins metacognitive therapy (MCT), posits that depression and anxiety become persistent when stored metacognitive beliefs guide an individual to respond to common thoughts and feelings in a certain way. We hypothesized that (i) metacognitive beliefs would predict depression and anxiety independently of participants' representations of their illness; and (ii) rumination would mediate independent prediction of depression and anxiety by metacognitive beliefs.

DESIGN

A prospective mediation study.

METHODS

Four hundred and forty-one adults with DM (Types 1 and 2) completed a two time-point survey. Metacognitive beliefs, illness representations and rumination were measured at baseline, and depression and anxiety measured at baseline and 6-months later. Data were analysed using structural equation modelling. Baseline illness representations, depression and anxiety were used as control variables.

RESULTS

A structural equation analysis showed potential mediation, by baseline rumination, of any effects of baseline metacognitive variables on 6-month distress in Type 1 and 2 diabetes samples. Significant standardized coefficients for relationships between the metacognitive latent variable and rumination were .67 (Type 1) and .75 (Type 2) and between rumination and distress of .36 and .43, respectively. These effects were independent of direct and independent effects of illness representation variables.

CONCLUSIONS

Findings are consistent with metacognitive beliefs playing a key role in depression and anxiety by increasing the likelihood of rumination in adults with DM. MCT may be an effective intervention for this population, subsequent to further longitudinal testing of the S-REF model.

Prevalence of post-traumatic stress and tests of metacognition as a PTSD risk marker in patients with coronary heart disease and elevated HADS scores: analysis of data from the PATHWAY RCT's in UK cardiac rehabilitation

Introduction

Anxiety and depression in coronary heart disease (CHD) are associated with poorer health outcomes, greater healthcare use and reduced quality of life. Post-traumatic stress symptoms may be a particular concern as they are associated with increased mortality at follow-up. We examined prevalence of PTSD in patients with elevated anxiety/depression scores referred for cardiac rehabilitation (CR) across seven NHS sites in North-West England. We tested a possible mechanism (metacognition) linking CHD to PTSD symptom severity as implicated in the metacognitive model.

Methods

Data was collected at baseline as part of the NIHR funded PATHWAY trial of metacognitive therapy for anxiety and depression in CHD. Patients (n = 572) with at least mild symptoms of anxiety and depression under routine screening (assessed with the Hospital Anxiety and Depression Scale) and attending CR were eligible for the study. A battery of questionnaires, including assessment of demographic variables, PTSD symptoms (using the IES-R) and metacognitive beliefs was administered prior to random allocation and intervention delivery.

Results

Rates of PTSD were high, with 48% of patients meeting threshold for PTSD and a further 15% partial PTSD. All five metacognition subscales were positively associated with PTSD vs. no PTSD, with beliefs about the uncontrollability and danger of worry and beliefs about need to control thoughts being most strongly related. For every unit increase in uncontrollability and danger metacognitions the odds of being in the PTSD group increased 30%, whilst the odds of partial PTSD increased 16%. Stepwise regression analysis using the metacognitive subscales along with demographic and health-related covariates found that uncontrollability/danger and need for control metacognitions explained unique variation in PTSD symptom severity, with unique contributions also for age, sex, and number of comorbidities.

Conclusion

PTSD symptoms appeared highly prevalent in the current CR sample. Metacognitive beliefs were individually associated with symptom severity with the strongest positive relationship observed for beliefs about uncontrollability and dangerousness of worry, followed by need to control thoughts. The results highlight the importance in assessing PTSD in CR patients and add support to implementing metacognitive therapy in CHD to target particular metacognition risk factors in anxiety, depression and PTSD.

Educational Intervention Effects on Depression and Anxiety in Patients after Myocardial Infarction: A Randomized Controlled Trial

Depression and anxiety in cardiovascular disease worsen the prognosis of patients. Treatments for these disorders often provide limited improvement. The present study aimed to test, for the first time, the impact of educational technology on anxiety and depressive symptoms in patients participating in a cardiac rehabilitation program. A 12-month randomized controlled trial was conducted, in which 207 patients were randomly assigned to either the experimental (n = 76) or control (n = 69) groups. The intervention involved a structured patient education program provided by medical students who had undergone specially designed training in cardiac rehabilitation. The primary outcomes were death, hospitalization, heart failure, and recurrent myocardial infarction. The study also assessed anxiety and depression. A year later, the experimental group showed a statistically significant decrease in anxiety and depression on the HADS scale, with reductions of 2.0 and 1.9 points, respectively (p < 0.05). The control group showed reductions of 1.5 and 1.2 points (p < 0.05). The difference in the Hamilton Rating Scale for Depression between the groups at 12 months was -1.29 in favor of the main group (95% CI, -0.7 to -1.88), and the standardized mean difference was 0.36 (95% CI, 0.03 to 0.69). No treatment-related adverse events were observed. The results suggest that educational interventions can have a positive impact on mental health. The study's strengths include a structured intervention, randomization, and long-term follow-up. The limitations include the lack of blinding of study participants and a relatively small sample size.

Predictors of health-related quality of life in outpatients with coronary heart disease

Introduction

Health-related quality of life (HRQoL) is an important treatment target in patients with coronary heart disease (CHD) and is associated with poor outcomes. Therefore, it is of clinical importance to identify the key determinants of HRQoL among these patients. There is, however, limited knowledge of how a comprehensive set of psychosocial factors influence HRQoL. We aimed to determine the relative associations of clinical and psychosocial factors with mental and physical components of HRQoL in a sample of CHD outpatients.

Methods

This cross-sectional study included 1,042 patients 2-36 (mean 16) months after a CHD event recruited from two general Norwegian hospitals with a combined catchment area making up 7% of the Norwegian population, representative with regards to demographic and clinical factors. We collected data on HRQoL, demographics, comorbidities, coronary risk factors, and psychosocial factors. HRQoL was assessed using the Short Form 12 (SF12), which comprises a Mental Component Scale (MCS), and the Physical Component Scale (PCS). Crude and multi-adjusted linear regression analyses were used to investigate the association between covariates and MCS and PCS.

Results

Mean age was 61 [standard deviation (SD) 10] years, 20% were females, 18% had type D personality, 20% significant depression symptoms, 14% significant symptoms of anxiety whereas 45% reported insomnia. The presence of type D personality (β: -0.19), significant symptoms of depression (β: -0.15), and the presence of insomnia (β: -0.13) were negatively associated with MCS, but not PCS in multi-adjusted analyses. The presence of chronic kidney disease (β: -0.11) was associated with reduced MCS, whereas the presence of chronic obstructive pulmonary disease (β: -0.08) and low physical activity (β: -0.14) were negatively associated with PCS. Younger age was associated with lower MCS, whereas older age was associated with lower PCS.

Discussion

We conclude that Type D personality, depressive symptoms, insomnia, and chronic kidney disease were the strongest determinants of the mental component of HRQoL. Assessing and managing these psychological factors among CHD outpatients may improve their mental HRQoL.

Internet-Delivered, Therapist-Assisted Treatment for Anxiety and Depression in Patients with Cardiovascular Disease: Evidence-Base and Challenges

PURPOSE OF REVIEW

This review focuses on the efficacy of internet-based psychological interventions for patients with cardiovascular disease (CVD) and comorbid anxiety and depression. Anxiety and depression comprise barriers for treatment adherence and are associated with poorer patient-reported and clinical outcomes, and greater health care costs.

RECENT FINDINGS

Internet-based, therapist-assisted interventions targeting anxiety and depression can be as efficacious as face-to-face therapy and may have some advantages, as patients can do it from their own laptop/smartphone at home at a time of their convenience, which may facilitate a better integration in their lives. To enhance the field of internet-based therapy for patients with CVD, we need to involve patients in the development of interventions, focus on developing standards for adherence and assessment of fidelity, and assess and augment health literacy in patients to safeguard equality in health care.

A framework for implementing Patient and Public Involvement in mental health research: The PATHWAY research programme benchmarked against NIHR standards

BACKGROUND

Patient and Public Involvement (PPI) in research has become a key component recommended by research commissioners, grant award bodies and specified in government policies. Despite the increased call for PPI, few studies have demonstrated how to implement PPI within large-scale research studies.

OBJECTIVE

The aim of the current study was to provide a case example of the implementation of a patient advisory group in a large-scale mental health research programme (PATHWAY) and to benchmark this against UK standards.

METHOD

A PPI group was incorporated throughout the PATHWAY research programme, from grant development to dissemination. The group attended regular meetings and supported participant recruitment, evaluated patient-facing documents, supported the piloting of the research intervention and co-developed the dissemination and impact strategy. The implementation of PPI throughout the project was benchmarked against the UK standards for PPI.

RESULTS

The inclusion of PPI in the PATHWAY project provided tangible changes to the research project (i.e., improving study documents, co-developing dissemination materials) but also proved to be a beneficial experience to PPI members through the development of new skills and the opportunity to provide a patient voice in research. We show how PPI was involved across seven study phases and provide examples of implementation of the six UK standards. The study did not include PPI in data analysis but met all the UK standards for PPI. Challenges regarding practical components (i.e., meeting frequency, language use), increasing diversity and PPI members' knowledge of research were highlighted as areas for further improvement.

CONCLUSIONS

We provide a case example of how PPI can be implemented throughout a research lifecycle and we note the barriers faced and make suggestions for PPI in future implementation and research.

PATIENT AND PUBLIC CONTRIBUTION

PPI members were involved throughout the lifecycle of the research programme. The PPI lead was a co-author on the manuscript and contributed to report writing.

Cognitive-behavioural therapy reduces psychological distress in younger patients with cardiac disease: a randomized trial

AIMS

To test whether usual outpatient cardiac rehabilitation (CR) supplemented by a cognitive-behavioural therapy (CBT) intervention may reduce anxiety and depression compared with usual CR.

METHODS AND RESULTS

In this multicentre randomized controlled trial, 147 cardiac patients (67% men, mean age 54 years, 92% with coronary artery disease) with psychological distress defined as a hospital anxiety and depression scale (HADS) anxiety or depression score ≥8 were randomized to five sessions of group CBT plus usual CR (intervention, n = 74) or CR alone (control, n = 73). Patients with severe distress or a psychiatric diagnosis were excluded. The intervention was delivered by cardiac nurses with CBT training and supervised by a psychologist. A reference, non-randomized group (background, n = 41) of consecutive patients without psychological distress receiving usual CR was included to explore the effect of time on HADS score. The primary outcome, total HADS score after 3 months, improved more in the intervention than in the control group [the mean total HADS score improved by 8.0 (standard deviation 5.6) vs. 4.1 (standard deviation 7.8), P < 0.001]. Significant between-group differences were maintained after 6 months. Compared with the control group, the intervention group also had greater adherence to CR (P = 0.003), more improvement in the heart-related quality of life (HeartQoL) at 6 months (P < 0.01), and a significant reduction in cardiac readmissions at 12 months (P < 0.01). The background group had no significant change in HADS score over time.

CONCLUSION

Brief CBT provided by cardiac nurses in relation to CR reduced anxiety and depression scores, improved HeartQoL and adherence to CR, and reduced cardiovascular readmissions. The programme is simple and may be implemented by CR nurses.

Protocol for the FACE study: frailty and comorbidity in elderly patients-a multicenter, Chinese observational cohort study

The present protocol describes an observational cohort study that was designed to propose a therapeutic scheme and formulate an individualized treatment strategy for frail elderly patients diagnosed with multiple diseases in a Chinese, multicenter setting. Over a 3-year period, we will recruit 30,000 patients from 10 hospitals and collect baseline data including patient demographic information, comorbidity characteristic, FRAIL scale, age-adjusted Charlson comorbidity index (aCCI), relevant blood tests, the results of imaging examination, prescription of drugs, length of hospital stay, number of overall re-hospitalizations and death. Elderly patients (≥ 65 years old) with multimorbidity and receiving hospital care are eligible for this study. Data collection is being performed at baseline and 3, 6, 9 and 12 months after discharge. Our primary analysis was all-cause death, readmission rate and clinical events (including emergency visits, stroke, heart failure, myocardial infarction, tumor, acute chronic obstructive pulmonary disease, etc). The study is approved by the National Key R & D Program of China (2020YFC2004800). Data will be disseminated in manuscripts submitted to medical journals and in abstracts submitted to international geriatric conferences. Clinical Trial Registration: [www.ClinicalTrials.gov], identifier [ChiCTR2200056070].

Metacognitive therapy home-based self-help for anxiety and depression in cardiovascular disease patients in the UK: A single-blind randomised controlled trial

BACKGROUND

Anxiety and depression in cardiac rehabilitation (CR) are associated with greater morbidity, mortality, and increased healthcare costs. Current psychological interventions within CR have small effects based on low-quality studies of clinic-based interventions with limited access to home-based psychological support. We tested the effectiveness of adding self-help metacognitive therapy (Home-MCT) to CR in reducing anxiety and depression in a randomised controlled trial (RCT).

METHODS AND FINDINGS

We ran a single-blind, multi-centre, two-arm RCT. A total of 240 CR patients were recruited from 5 NHS-Trusts across North West England between April 20, 2017 and April 6, 2020. Patients were randomly allocated to Home-MCT+CR (n = 118, 49.2%) or usual CR alone (n = 122, 50.8%). Randomisation was 1:1 via randomised blocks within hospital site, balancing arms on sex and baseline Hospital Anxiety and Depression Scale (HADS) scores. The primary outcome was the HADS total score at posttreatment (4-month follow-up). Follow-up data collection occurred between August 7, 2017 and July 20, 2020. Analysis was by intention to treat. The 4-month outcome favoured the MCT intervention group demonstrating significantly lower end of treatment scores (HADS total: adjusted mean difference = -2.64 [-4.49 to -0.78], p = 0.005, standardised mean difference (SMD) = 0.38). Sensitivity analysis using multiple imputation (MI) of missing values supported these findings. Most secondary outcomes also favoured Home-MCT+CR, especially in reduction of post-traumatic stress symptoms (SMD = 0.51). There were 23 participants (19%) lost to follow-up in Home-MCT+CR and 4 participants (3%) lost to follow-up in CR alone. No serious adverse events were reported. The main limitation is the absence of longer term (e.g., 12-month) follow-up data.

CONCLUSION

Self-help home-based MCT was effective in reducing total anxiety/depression in patients undergoing CR. Improvement occurred across most psychological measures. Home-MCT was a promising addition to cardiac rehabilitation and may offer improved access to effective psychological treatment in cardiovascular disease (CVD) patients.

Patient Preferences for Cardiac Rehabilitation - A Systematic Review

BACKGROUND

Although a large number of studies have demonstrated the effectiveness of cardiac rehabilitation(CR), patient preferences for CR remain unclear. Knowing patient preferences may contribute to increasing patient participation and adherence, thus improving patient prognosis.

METHODS

A systematic search was carried out using electronic databases and manual reference checks from inception until 15th June 2022. Quantitative studies, qualitative studies and mixed methods studies assessing patient preferences for CR were included. Two researchers independently conducted study selectionand data extraction. CR preferences were divided into three categories: CR settings, CR components, and CR contents. A narrative synthesis was applied to integrate the results of the included studies. The Mixed Methods Appraisal Tool (MMAT) was used to assess the quality of included studies.

RESULTS

Ultimately, 17 publications were included in this study. Regarding CR settings, most patients preferred the hospital to home, some considered both, and a few were willing to accept the local CR club as an alternative setting to the hospital. For CR components, regardless of age and gender, patients considered exercise training and nutrition counseling to be the most important and smoking cessation to be the least important. In exercise intervention of CR contents, progress discussion and encouragement were rated as most critical, and non-conflicting with other activities was rated as least critical. In psychological intervention of CR contents, most patients were willing to accept psychological intervention, and a few patients wanted to heal the trauma with the passage of time.

CONCLUSION

This systematic review provides important insights into patient preferences for CR, clarifying patient preferences for CR settings, components, and contents, along with possible influencing factors. Patient preferences may change due to the COVID-19 epidemic, and there is still a need to focus on patient preferences for CR and conduct more relevant primary research to validate the findings of this paper in the future.

Discrete choice experiment to investigate preferences for psychological intervention in cardiac rehabilitation

OBJECTIVE

Cardiac rehabilitation (CR) is offered to people who recently experienced a cardiac event, and often comprises of exercise, education and psychological care. This stated preference study aimed to investigate preferences for attributes of a psychological therapy intervention in CR.

METHODS

A discrete choice experiment (DCE) was conducted and recruited a general population sample and a trial sample. DCE attributes included the modality (group or individual), healthcare professional providing care, information provided prior to therapy, location and the cost to the National Health Service (NHS). Participants were asked to choose between two hypothetical designs of therapy, with a separate opt-out included. A mixed logit model was used to analyse preferences. Cost to the NHS was used to estimate willingness to pay (WTP) for aspects of the intervention design.

RESULTS

Three hundred and four participants completed the DCE (general public sample (n=262, mean age 47, 48% female) and trial sample (n=42, mean age 66, 45% female)). A preference for receiving psychological therapy was demonstrated by both samples (general population WTP £1081; 95% CI £957 to £1206). The general population appeared to favour individual therapy (WTP £213; 95% CI £160 to £266), delivered by a CR professional (WTP £48; 9% % CI £4 to £93) and with a lower cost (β=-0.002; p&lt;0.001). Participants preferred to avoid options where no information was received prior to starting therapy (WTP -£106; 95% CI -£153 to -£59). Results for the location attribute were variable and challenging to interpret.

CONCLUSIONS

The study demonstrates a preference for psychological therapy as part of a programme of CR, as participants were more likely to opt-in to therapy. Results indicate that some aspects of the delivery which may be important to participants can be tailored to design a psychological therapy. Preference heterogeneity is an issue which may prevent a 'one-size-fits-all' approach to psychological therapy in CR.

Relationships between depression, anxiety, type D personality, and worry and rumination in patients with coronary heart disease

Psychological distress, including depression and anxiety, and Type-D personality are prevalent in patients with coronary heart disease (CHD) and associated with poor cardiovascular outcomes. Worry and rumination may be among the core features responsible for driving psychological distress in these patients. However, the nature of associations between these constructs remains to be delineated, yet they may have implications for the assessment and treatment of CHD patients. This study aimed to (1) explore the factorial structure and potential overlap between measures of depression, anxiety and the Type-D personality factors known as negative affectivity and social inhibition, and (2) examine how these constructs relate to worry and rumination in a sample of 1,042 CHD outpatients who participated in the in the cross-sectional NORwegian CORonary Prevention study. We conducted confirmatory factor analyses (n = 1,042) and regression analyses (n = 904) within a structural equation modeling framework. Results showed all constructs to have acceptable factor structure and indicated an overlap between the constructs of depression and negative affectivity. Worry was most strongly associated with anxiety, whereas rumination was most strongly associated with depression and negative affectivity. The results suggest conceptual similarities across the measures of depression and negative affectivity. They further suggest that intervention efforts could benefit from targeting worry and/or rumination in the treatment of CHD outpatients presenting with symptoms of psychological distress.

Psychosocial impacts of spontaneous coronary artery dissection: A qualitative study

Spontaneous coronary artery dissection (SCAD) is an increasingly recognised cause of acute myocardial infarction, particularly in younger women without classic cardiac risk factors. While recent quantitative studies have noted high anxiety and depression in SCAD survivors, the full range and extent of psychosocial impacts of SCAD is unknown. The present study used a qualitative approach to investigate the psychosocial impacts of SCAD in Australian SCAD survivors. Focus group participants were recruited as part of a larger study of SCAD survivors currently being undertaken by the Victor Chang Cardiac Research Institute. Thirty SCAD survivors participated in one of seven online focus groups, conducted using a semi-structured format. Focus group duration was 1.5 hours. Each was digitally recorded and transcribed. Data were analyzed thematically according to recommended guidelines. One over-arching theme, five main themes and 26 sub-themes were identified. The over-arching theme related to lack of information, while the five main themes related to emotional impacts, issues with self-management, issues with family, impacts on work life, and the need for psychosocial support. The ‘emotional impacts’ theme comprised 11 sub-themes, namely shock and disbelief, confusion and uncertainty, unfairness, fear and anxiety, loss and grief, isolation and loneliness, guilt, invalidation and embarrassment, depression, vulnerability, and frustration. Findings are discussed in light of relevant psychological theories. This qualitative study extends previous quantitative investigations of SCAD survivors by providing an in-depth understanding of the complex, inter-related and highly distressing impacts of SCAD. The findings point to the urgent need for a coherent approach to information provision, the development and delivery of SCAD-specific cardiac rehabilitation programs, and the provision of psychosocial support programs for SCAD survivors.

The Attention Training Technique Reduces Anxiety and Depression in Patients With Coronary Heart Disease: A Pilot Feasibility Study

Background and Objectives

Depression and anxiety symptoms are highly prevalent in coronary heart disease (CHD) patients and associated with poor outcome. Most psychological treatments have shown limited effectiveness on anxiety and depression in these patients. This study evaluates the feasibility of the attention training technique (ATT) in CHD patients with symptoms of anxiety and/or depression.

Methods

Five consecutive CHD patients with significant depression and anxiety symptoms with Hospital Anxiety and Depression rating scale (HADS) -anxiety or -depression subscale score > 8 received 6 weekly group-sessions of ATT in an open trial. Outcomes included feasibility and symptoms measured by HADS, at baseline, post-treatment and at 6 months follow-up. We also assessed psychiatric diagnoses, type D personality, insomnia, worry, and rumination.

Results

The sample comprised five men with a mean age of 59.9 (SD 4.4) years. Four of the patients attended all six sessions, and one patient attended all but one session. Mean HADS-A scores at baseline, post-treatment, and follow-up were 9.4 (SD 3.0), 4.2 (SD 3.0), and 4.0 (SD 2.5), and for HADS-D 8.6 (SD 3.3), 3.0 (SD 3.7), and 1.6 (SD 1.5), respectively. The results showed clinically significant changes in anxiety, depression, psychiatric disorders, insomnia, worry, and rumination. Statistically significant changes were found from pre- to post-treatment scores for HADS-A and worry, which were maintained at follow-up, and HADS-D scores significantly decreased from pre-treatment to 6-months follow-up.

Conclusions

ATT in a group format appears to be a feasible stand-alone metacognitive treatment for CHD patients. An adequately powered randomized controlled trial is warranted.

Prognostic value of functional capacity after transitional rehabilitation in older patients hospitalized for heart failure

BACKGROUND

Poor functional status is highly prevalent among older patients hospitalized for HF and marks a downward inflection point in functional and prognostic trajectories. We assessed the prognostic value of 6-min walk test after transitional cardiac rehabilitation in older patients hospitalized for heart failure (HF).

METHODS

We studied 759 patients aged ≥60 years who had been transferred to six inpatient rehabilitation facilities (IRF) from acute care hospitals after a hospitalization for acute HF. The primary outcome was 3-year all-cause mortality. We used multivariable Cox analysis to determine the association between 6-min walk distance (6MWD) at discharge from the IRFs and the primary outcome, adjusting for established predictors of death. The optimal cutoff for 6MWD was considered as the one that maximized the chi-square statistic.

RESULTS

Mean age was 75 ± 8 years. 6MWD significantly increased from admission to discharge (145 to 210 m; p < 0.001). The optimal cutoff for 6MWD was 198 m. After full adjustment, the hazard ratio for each 50 m-increase in discharge 6MWD was 0.90 (0.87-0.94; p < 0.001) and that for discharge 6MWD dichotomized at the optimal cutoff 0.48 (0.38-0.60; p < 0.001). The incidence rate of death/100 person-years for the patients who walked >198 m was 13.0 (10.0-15.5) compared with 30.8 (26.9-35.4) for those who walked <198 m. A statistically significant interaction of discharge 6MWD with left ventricular ejection fraction (EF) on the risk of death was observed (p value for interaction 0.047).

CONCLUSIONS

A rehabilitation intervention provided in the critical hospital-to-home transition period to older patients hospitalized for HF resulted in improved functional capacity. Increasing levels of functional capacity following rehabilitation were closely associated with decreasing risk of death; this association was significantly stronger for the subgroup with preserved EF.

Takotsubo Syndrome: Pathophysiology, Emerging Concepts, and Clinical Implications

Takotsubo syndrome is a condition characterized by acute transient left ventricular systolic dysfunction, which at presentation can be challenging to distinguish from acute myocardial infarction. Although previously thought to be a benign, self-limiting condition, recent studies have confirmed that patients with takotsubo syndrome have persistent subtle ongoing cardiac dysfunction, and many continue to have limiting symptoms despite restoration of left ventricular ejection fraction. Moreover, these patients have a substantial burden of morbidity as well as mortality with high rates of subsequent major adverse cardiovascular events that approach those of patients with acute coronary syndrome. The mechanisms behind this condition remain elusive. Despite substantial research, the medical community continues to have an incomplete understanding of its underlying etiology and pathophysiology. Catecholamine-induced myocardial injury is the most established and well-known theory, but this does not explain all of the clinical features and presentations of the condition, and numerous other pathways and abnormalities are emerging. Because of the poor understanding of its underlying pathophysiology, there is a lack of evidence-based interventions to treat the acute episode, to avoid recurrences and to prevent major adverse cardiovascular events. This highlights the need for further research to gain a better understanding of the underlying pathophysiology in order to inform appropriate randomized controlled trials of interventions targeting the causative pathways. Only then can evidence-based management strategies be established to improve clinical outcomes of this potentially lethal condition.

Systematic screening for anxiety and depression in cardiac rehabilitation - are we there yet?

BACKGROUND

Anxiety and depression are prevalent in 20% of patients with acute coronary syndrome (ACS) and associated with poor outcomes. Guidelines recommend screening for these conditions in cardiac rehabilitation (CR) however, clinical practice is inconsistent. Sparse knowledge exists on determinants for screening.

METHODS

This observational study used data from the National Audit of Cardiac Rehabilitation from January 2016-December 2019. A multivariate logistic regression model was performed to analyze patient- and provider level determinants for screening for anxiety and depression among patients with ACS.

RESULTS

The population consisted of 138,018 patients, where 82,507 (59.8%) were screened and 55,511 (40.2%) were not. Younger age, non-white ethnicity, living in areas of social deprivation, current smoking, body mass index>30, and physical activity<150 min per week were negatively correlated with patients being screened. Compared to patients having a percutaneous coronary intervention, patients undergoing coronary artery bypass grafting or medical treatment were less likely to be screened. History of anxiety, depression, osteoporosis, chronic back problems, and asthma were positively correlated with screening, while chronic obstructive pulmonary disease, diabetes, hypertension, and stroke were negatively correlated with screening. Regarding provider level, certification of CR centers was positively associated with screening, while looking over time data showed an incremental negative trend in screening from 2016 to 2019.

CONCLUSION

We found both patient and provider level determinants of screening for anxiety and depression. Clinical practice is still inconsistent especially for high-risk groups. We recommend systematic screening to enable tailored interventions which in turn may mitigate inequity in health outcomes.

Twelve-month outcomes in overweight/obese users with mental disorders following a multi-element treatment including diet, physical activity, and positive thinking: The real-world "An Apple a Day" controlled trial

The present study aimed to evaluate the 12-month effectiveness of a real-world weight loss transdiagnostic intervention in overweight/obese participants affected by mental disorders under psychopharmacological treatment. We conducted a real-world, controlled, pragmatic outpatient trial. We allocated 58 overweight/obese adults under psychopharmacological treatment from a mental health outpatient unit and 48 overweight/obese adults from a cardiovascular prevention outpatient unit, and assigned them to an intervention or treatment usual as condition (TAU) enriched by life-style advice. Participants in both intervention groups took part in a diet programme (the modified OMNIHeart dietary protocol) and monitoring of regular aerobic activity. A brief group programme ("An Apple a Day" Metacognitive Training, Apple-MCT) was added in the intervention group of participants affected by mental disorders. The primary outcome was weight loss. Secondary outcomes included anthropometric, clinical, and metabolic variables. Psychopathology and health-related quality of life were also evaluated in the psychiatric sample. At 12 months, both intervention groups showed a more marked mean decrease in weight (6.7 kg, SD: 3.57) than the TAU group (0.32 kg, SD: 1.96), and a statistically significant improvement in metabolic variables compared with the control groups. Furthermore, the participants affected by mental disorders included in the intervention group reported improved health-related quality of life. Our findings suggest the need to implement integrated interventions based on a dietary protocol, physical activity, and modification of cognitive style in overweight/obese users with mental disorders.

Evaluating Metacognitive Therapy to Improve Treatment of Anxiety and Depression in Cardiovascular Disease: The NIHR Funded PATHWAY Research Programme

BACKGROUND

Anxiety and depression contribute to poorer physical and mental health outcomes in cardiac patients. Psychological treatments are not routinely offered in cardiac care and have mixed and small effects. We conducted a series of studies under the PATHWAY research programme aimed at understanding and improving mental health outcomes for patients undergoing cardiac rehabilitation (CR) through provision of metacognitive therapy (MCT).

METHODS

PATHWAY was a series of feasibility trials, single-blind, multicenter, randomized controlled trials (RCTs), qualitative, stated preferences for therapy and health economics studies.

FINDINGS

Patients felt their psychological needs were not met in CR and their narratives of distress could be parsimoniously explained by the metacognitive model. Patients reported they would prefer therapy over no therapy as part of CR, which included delivery by a cardiac professional. Two feasibility studies demonstrated that RCTs of group-based and self-help MCT were acceptable, could be embedded in CR services, and that RCTs of these interventions were feasible. A definitive RCT of group-MCT within CR (n = 332) demonstrated significantly greater reductions in the severity of anxiety and depression, exceeding CR alone, with gains maintained at 12 month follow-up (SMD HADS total score = 0.52 at 4 months and 0.33 at 12 months). A definitive trial of self-help MCT is ongoing.

CONCLUSION

There is a need to better meet the psychological needs of CR patients. Embedding MCT into CR demonstrated high acceptability and improved efficacy on psychological outcomes. Results support roll-out of MCT in CR with evaluation of national implementation.

Transdiagnostic Cognitive-Behavioral Therapy for Depression and Anxiety Disorders in Cardiovascular Disease Patients: Results From the CHAMPS Pilot-Feasibility Trial

OBJECTIVE

The aim of the Cardiovascular Health in Anxiety and Mood Problems Study (CHAMPS) is to pilot the Unified Protocol (UP) for the transdiagnostic treatment of depression and anxiety disorders in patients recently hospitalized for cardiovascular diseases (CVDs) and evaluate the feasibility.

METHODS

The present study is a controlled, block randomized pragmatic pilot-feasibility trial incorporating qualitative interview data, comparing UP (n = 9) with enhanced usual care (EUC, n = 10). Eligible trial participants had a recent CVD-cause admission and were above the severity threshold for depression or anxiety denoted by Patient Health Questionnaire (PHQ-9) total scores ≥10 and/or Generalized Anxiety Disorder (GAD-7) total scores ≥7 respectively on two occasions, and met criteria for one or more depression or anxiety disorders determined by structured clinical interview. Study outcomes were analyzed as intention-to-treat using linear mixed models and qualitative interview data were analyzed with content analysis.

RESULTS

Quantitative and qualitative measured indicated acceptability of the transdiagnostic CBT intervention for CVD patients with depression or anxiety disorders. Satisfaction with UP was comparable to antidepressant therapy and higher than general physician counseling. However, there were difficulties recruiting participants with current disorders and distress on two occasions. The UP was associated with a reduction in total number of disorders determined by blinded raters. Linear mixed models indicated that a significantly greater reduction in anxiety symptoms was evident in the UP group by comparison to the EUC group (GAD-7, p between groups = 0.011; Overall Anxiety Severity and Impairment Scale, p between groups = 0.013). Results favored the UP group by comparison to EUC for change over 6 months on measures of physical quality of life and harmful alcohol use. There was no difference between the two groups on changes in depression symptoms (PHQ-9), stress, metacognitive worry beliefs, physical activity, or adherence.

DISCUSSION

In conclusion, this feasibility trial indicates acceptability of transdiagnostic CBT intervention for CVD patients with depression or anxiety disorders that is tempered by difficulties with recruitment. Larger trials are required to clarify the efficacy of transdiagnostic depression and anxiety disorder CBT in populations with CVDs and depressive or anxiety disorders.

Association of Mental Stress-Induced Myocardial Ischemia With Cardiovascular Events in Patients With Coronary Heart Disease

Importance

Mental stress-induced myocardial ischemia is a recognized phenomenon in patients with coronary heart disease (CHD), but its clinical significance in the contemporary clinical era has not been investigated.

Objective

To compare the association of mental stress-induced or conventional stress-induced ischemia with adverse cardiovascular events in patients with CHD.

Design, Setting, and Participants

Pooled analysis of 2 prospective cohort studies of patients with stable CHD from a university-based hospital network in Atlanta, Georgia: the Mental Stress Ischemia Prognosis Study (MIPS) and the Myocardial Infarction and Mental Stress Study 2 (MIMS2). Participants were enrolled between June 2011 and March 2016 (last follow-up, February 2020).

Exposures

Provocation of myocardial ischemia with a standardized mental stress test (public speaking task) and with a conventional (exercise or pharmacological) stress test, using single-photon emission computed tomography.

Main Outcomes and Measures

The primary outcome was a composite of cardiovascular death or first or recurrent nonfatal myocardial infarction. The secondary end point additionally included hospitalizations for heart failure.

Results

Of the 918 patients in the total sample pool (mean age, 60 years; 34% women), 618 participated in MIPS and 300 in MIMS2. Of those, 147 patients (16%) had mental stress-induced ischemia, 281 (31%) conventional stress ischemia, and 96 (10%) had both. Over a 5-year median follow-up, the primary end point occurred in 156 participants. The pooled event rate was 6.9 per 100 patient-years among patients with and 2.6 per 100 patient-years among patients without mental stress-induced ischemia. The multivariable adjusted hazard ratio (HR) for patients with vs those without mental stress-induced ischemia was 2.5 (95% CI, 1.8-3.5). Compared with patients with no ischemia (event rate, 2.3 per 100 patient-years), patients with mental stress-induced ischemia alone had a significantly increased risk (event rate, 4.8 per 100 patient-years; HR, 2.0; 95% CI, 1.1-3.7) as did patients with both mental stress ischemia and conventional stress ischemia (event rate, 8.1 per 100 patient-years; HR, 3.8; 95% CI, 2.6-5.6). Patients with conventional stress ischemia alone did not have a significantly increased risk (event rate, 3.1 per 100 patient-years; HR, 1.4; 95% CI, 0.9-2.1). Patients with both mental stress ischemia and conventional stress ischemia had an elevated risk compared with patients with conventional stress ischemia alone (HR, 2.7; 95% CI, 1.7-4.3). The secondary end point occurred in 319 participants. The event rate was 12.6 per 100 patient-years for patients with and 5.6 per 100 patient-years for patients without mental stress-induced ischemia (adjusted HR, 2.0; 95% CI, 1.5-2.5).

Conclusions and Relevance

Among patients with stable coronary heart disease, the presence of mental stress-induced ischemia, compared with no mental stress-induced ischemia, was significantly associated with an increased risk of cardiovascular death or nonfatal myocardial infarction. Although these findings may provide insights into mechanisms of myocardial ischemia, further research is needed to assess whether testing for mental stress-induced ischemia has clinical value.

Cardiac rehabilitation patients experiences and understanding of group metacognitive therapy: a qualitative study

OBJECTIVE

Depression and anxiety are up to three times more prevalent in cardiac patients than the general population and are linked to increased risks of future cardiac events and mortality. Psychological interventions for cardiac patients vary in content and are often associated with weak outcomes. A recent treatment, metacognitive therapy (MCT) has been shown to be highly effective at treating psychological distress in mental health settings. This is the first study to explore qualitatively, cardiac rehabilitation (CR) patients' experiences and understanding of group MCT with the aim of examining aspects of treatment that patients experienced as helpful.

METHODS

In-depth qualitative interviews were conducted with 24 purposively sampled CR patients following group MCT. Data were analysed using thematic analysis.

RESULTS

Two main themes were identified: (1) general therapy factors that were seen largely as beneficial, where patients highlighted interaction with other CR patients and CR staff delivery of treatment and their knowledge of cardiology; (2) group MCT-specific factors that were seen as beneficial encompassed patients' understanding of the intervention and use of particular group MCT techniques. Most patients viewed MCT in a manner consistent with the metacognitive model. All the patients who completed group MCT were positive about it and described self-perceived changes in their thinking and well-being. A minority of patients gave specific reasons for not finding the treatment helpful.

CONCLUSION

CR patients with anxiety and depression symptoms valued specific group MCT techniques, the opportunity to learn about other patients, and the knowledge of CR staff. The data supports the transferability of treatment to a CR context and advantages that this might bring.
