The prevalence and impact of depression and anxiety in cardiac rehabilitation: A longitudinal cohort study

Predictors of Health-Related Quality of Life Among Women Participating in an Appointment-Based Cardiac Rehabilitation Program

BACKGROUND

An alternative patient-centered appointment-based cardiac rehabilitation (CR) program has led to significant improvements in health outcomes for patients with cardiovascular disease. However, less is known about the effects of this approach on health-related quality of life (HRQoL), particularly for women.

OBJECTIVE

We examined the effects of a patient-centered appointment-based CR program on HRQoL by sex and examined predictors of HRQoL improvements specifically for women.

METHODS

Data were used from an urban single-center CR program at Yale New Haven Health (2012-2017). We collected information on patient demographics, socioeconomic status, and clinical characteristics. The Outcome Short-Form General Health Survey (SF-36) was used to measure HRQoL. We evaluated sex differences in SF-36 scores using t tests and used a multivariate linear regression model to examine predictors of improvements in HRQoL (total SF-36 score) for women.

RESULTS

A total of 1530 patients with cardiovascular disease (23.7% women, 4.8% Black; mean age, 64 ± 10.8 years) were enrolled in the CR program. Women were more likely to be older, Black, and separated, divorced, or widowed. Although women had lower total SF-36 scores on CR entry, there was no statistically significant difference in CR adherence or total SF-36 score improvements between sexes. Women who were employed and those with chronic obstructive pulmonary disease were more likely to have improvements in total SF-36 scores.

CONCLUSION

Both men and women participating in an appointment-based CR program achieved significant improvements in HRQoL. This approach could be a viable alternative to conventional CR to optimize secondary outcomes for patients.

Effectiveness of virtual reality in cardiac rehabilitation patients for exercise capacity and negative emotions: A systematic review and meta-analysis

BACKGROUND

The significance of virtual reality (VR) technology as an alternative or complementary modality to traditional cardiac rehabilitation is of increasing interest. Numerous studies have examined the effects of virtual reality technology in cardiac rehabilitation patients, but the results have been inconsistent.

METHODS

We conducted a systematic search of the Cochrane Library, Web of Science, PubMed, Embase, Scopus, ProQuest, OVID, CINAHL, SinoMed, CNKI, WanFang, VIP Database, and ReadShow databases following the Program for Systematic Review and Meta-Analysis guidelines. The search included studies published up until June 30, 2024. The Cochrane Risk of Bias Tool was used to examine the methodological quality of the included randomized controlled studies. When feasible, a meta-analysis was performed to calculate the pooled effects using Review Manager (version 5.3). Otherwise, narrative summaries were performed.

RESULTS

A total of 11 studies with 1093 patients were included. The results of systematic review and meta-analysis showed that virtual reality technology improved patients' exercise capacity (mean difference: 53.26, 95% confidence interval [CI]: 45.14-61.37; P < .00001); anxiety (standardized mean difference [SMD]: -0.39, 95% CI: -0.69, -0.08, P = .01); depression (SMD: -0.48, 95% CI: -0.79, -0.17; P = .003); stress (SMD: -0.72, 95% CI: -1.03, -0.40; P < .00001); emotional tension (SMD: -0.81, 95% CI: -1.15, -0.47; P < .00001); emotional tension (SMD: -0.64, 95% CI: -0.98, -0.30; P = .0002), and intrapsychic stress (SMD: -0.56, 95% CI: -0.90, -0.23; P = .0009).

CONCLUSION

Virtual reality-based interventions can be effective in improving patients' exercise capacity and negative emotions. However, further research is needed to determine the efficacy of VR for other clinical outcomes.

The heterogeneous depression trajectory and its predictors in coronary heart disease patients undergoing home-based cardiac rehabilitation: a cohort study

BACKGROUND

Psychological management, particularly addressing depression, is crucial for the effectiveness of home-based cardiac rehabilitation. This study aimed to explore the depression trajectories of coronary heart disease patients during home-based cardiac rehabilitation, identify trajectories associated with cardiovascular readmission, and integrate them into a heterogeneous depression trajectory while examining its predictors.

METHODS

A prospective cohort study was conducted at a large cardiac rehabilitation center in mainland China. Participants completed the Patient Health Questionnaire-9 to assess depression levels during the 6-month home-based cardiac rehabilitation, with monthly follow-ups. Using latent class growth models to explore depression trajectories. The relationship between different trajectories and cardiovascular readmission was determined using Cox proportional hazards regression, identifying heterogeneous depression trajectory. Logistic regression analysis was employed to explore the influencing factors of heterogeneous depression trajectory.

RESULTS

A total of 346 eligible patients with coronary heart disease participated in the study. Four distinct depression trajectories were identified: sustained no depression (48.0%), delayed onset (15.9%), low U-shaped depression (25.1%), and sustained depression (11.0%). Depression trajectories significantly impacted cardiovascular readmission rates, with higher risks observed in the delayed onset (HR: 4.707, 95% CI: 1.766-12.544) and sustained depression (HR: 8.832, 95% CI: 3.281-23.773) groups. These two groups were combined and termed heterogeneous depression trajectory. Importantly, education level, number of chronic diseases, resilience, social support, and anxiety were independent predictors of heterogeneous depression trajectory.

CONCLUSIONS

Depression trajectories during home-based cardiac rehabilitation are significantly heterogeneous and influence cardiovascular outcomes. Early identification and management of high-risk factors can enhance psychological health and reduce readmission rates.

Predictors of Cardiac Rehabilitation Attendance and Completion: Analysis of 33,055 Patients from the Queensland Cardiac Outcomes Registry (2020-2022)

AIM

Cardiac rehabilitation (CR) under-attendance presents a global challenge. The Queensland Cardiac Outcomes Registry is a comprehensive clinical registry that routinely collects point-of-care CR data. We aimed to determine whether demographic, clinical, psychosocial, and behavioural characteristics of the population vary between those who (i) declined, (ii) commenced but did not complete, and (iii) completed CR.

METHODS

The cohort comprised 33,055 patients referred to one of 56 Queensland CR services extracted from the Queensland Cardiac Outcomes Registry (2020-2022). Bivariate and multivariable logistic regression analyses were used to identify factors associated with CR non-attendance and non-completion.

RESULTS

Over the study period, 12,152 patients (37%) declined CR, 11,621 (35%) initiated but did not complete CR, and 9,282 (28%) completed CR. Significant predictors of CR non-attendance were aged ≥75 years (adjusted odds ratio [aOR] 1.51; 95% confidence interval [CI] 1.42-1.61), Indigenous status (aOR 1.65; 95% CI 1.50-1.81), living regionally (aOR 1.76; 95% CI 1.65-1.87) or remotely (aOR 2.33; 95% CI 1.92-2.82), and having arrhythmia (aOR 2.38; 95% CI 2.07-2.73), heart failure (aOR 1.54; 95% CI 1.37-1.74), non-ST-elevation myocardial infarction (aOR 1.30; 95% CI 1.21-1.40) or unstable angina (aOR 1.24; 95% CI 1.1.13-1.37). Significant predictors of CR non-completion were age <55 years (aOR 1.55; 95% CI 1.37-1.75), Indigenous status (aOR 1.60; 95% CI 1.29-1.98), living regionally (aOR 1.29; 95% CI 1.12-1.48), obesity (aOR 1.14; 95% CI 1.01-1.28), being a current (aOR 1.97; 95% CI 1.70-2.27) or former smoker (aOR:1.22, 95% CI 1.11-1.33) and having low social support (aOR 1.58; 95% CI 1.24-2.02).

CONCLUSION

As one of the largest studies of CR participation to date, these findings can now be applied to develop targeted, co-designed initiatives to enhance CR participation, especially among First Nations populations, smokers, those with limited social support, people living regionally/remotely, patients with arrhythmia and heart failure, and those in varying age groups.

Core Components of Cardiac Rehabilitation Programs: 2024 Update: A Scientific Statement From the American Heart Association and the American Association of Cardiovascular and Pulmonary Rehabilitation

The science of cardiac rehabilitation and the secondary prevention of cardiovascular disease has progressed substantially since the most recent American Heart Association and American Association of Cardiovascular and Pulmonary Rehabilitation update on the core components of cardiac rehabilitation and secondary prevention programs was published in 2007. In addition, the advent of new care models, including virtual and remote delivery of cardiac rehabilitation services, has expanded the ways that cardiac rehabilitation programs can reach patients. In this scientific statement, we update the scientific basis of the core components of patient assessment, nutritional counseling, weight management and body composition, cardiovascular disease and risk factor management, psychosocial management, aerobic exercise training, strength training, and physical activity counseling. In addition, in recognition that high-quality cardiac rehabilitation programs regularly monitor their processes and outcomes and engage in an ongoing process of quality improvement, we introduce a new core component of program quality. High-quality program performance will be essential to improve widely documented low enrollment and adherence rates and reduce health disparities in cardiac rehabilitation access.

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.

Efficacy of the Simulation-Based Education Approach Enhanced by Music on Anxiety, Physical Activity, and Respiratory Outcomes in Patients under Open Heart Surgery: A Randomized Three-Group Clinical Study

Background

Many patients with advanced cardiovascular disease need Coronary Artery Bypass Graft (CABG) surgery, indicating the importance of cardiac rehabilitation. Our study explored the combined efficacy of simulation (using demonstration and return-demonstration approach) with music on post-Open Heart Surgery (OHS) outcomes.

Materials and Methods

This randomized, controlled trial was conducted at Imam Reza Hospital, Mashhad, Iran, on 90 patients awaiting OHS. The participants were allocated to 3 groups: education via simulation, education via simulation enhanced by instrumental music, and conventional instruction. Evaluations were performed pre-education and 2-days post-surgery using the activity measure for post-acute care (AM-PAC) "6-Clicks" Questionnaire, 18-item Nursing Outcomes Classification (NOC) index, and State-Trait Anxiety Inventory (STAI). JASP software (JASP Team, 2023, Version 0.17.3) was employed for statistical analyses, using RM-ANOVA and ANCOVA test.

Results

The results revealed a significant effect in immediate post-intervention and 2-day follow-up periods across all outcome measures (all p < 0.05), except for activity. Post hoc tests demonstrated substantial variations in effect sizes between intervention and control groups. Both intervention groups had significantly greater impact than the control group, particularly the composite group, showing heightened effects in state and trait anxiety and respiratory scores (p < 0.05).

Conclusions

The combined use of the simulation with rhythmic music in phase one cardiac rehabilitation notably improved post-surgical outcomes, outperforming the method without music. This approach shows promise as an effective instructional strategy in cardiac rehabilitation stages.

Factors predicting depression among persons post-coronary artery bypass graft surgery: A cross-sectional study in Thailand

Background

Coronary artery bypass graft (CABG) surgery is a highly effective coronary artery disease treatment, providing immediate relief and promising long-term benefits. However, it is a major procedure with significant risks, including the potential for depression. Many patients experience depression following CABG, which can negatively impact their overall recovery, affecting both physical and mental health.

Objective

This study aimed to determine factors predicting depression in patients following CABG surgery.

Methods

This cross-sectional study was conducted with data collected between January and April 2024. A total of 272 post-CABG patients from two super tertiary care hospitals in Bangkok, Thailand, were recruited through purposive sampling. All research instruments were validated and tested for reliability. Data were analyzed using multiple regression analysis.

Results

The study found that hope, optimism, illness perception, social support, and anxiety were correlated with depression (adjusted R² = 0.381), but these variables explained only 38.1% of the variance (p <0.05). Among these factors, anxiety (β = 0.311), optimism (β = 0.203), social support (β = -0.117), and illness perception (β = -0.143) were significant predictors (p <0.05), while hope was not a significant predictor. Thus, anxiety emerged as the most crucial predictor of depression in patients who have undergone CABG.

Conclusion

Nurses play a vital role in preventing and managing depression in post-CABG patients. Screening for anxiety and addressing it can prevent depression, enhance social support, and improve outcomes. To develop effective nursing strategies, it is essential for nurses to assess anxiety and implement interventions that promote social support, optimism, and illness perception. These measures can improve care quality, reduce readmission rates, and enhance patients' overall quality of life.

Multicomponent Support Program for Secondary Prevention of Stroke Using Digital Health Technology: Co-Design Study With People Living With Stroke or Transient Ischemic Attack

BACKGROUND

Few individuals (<2%) who experience a stroke or transient ischemic attack (TIA) participate in secondary prevention lifestyle programs. Novel approaches that leverage digital health technology may provide a viable alternative to traditional interventions that support secondary prevention in people living with stroke or TIA. To be successful, these strategies should focus on user needs and preferences and be acceptable to clinicians and people living with stroke or TIA.

OBJECTIVE

This study aims to co-design, with people with lived experience of stroke or TIA (referred to as consumers) and clinicians, a multicomponent digital technology support program for secondary prevention of stroke.

METHODS

A consumer user needs survey (108 items) was distributed through the Australian Stroke Clinical Registry and the Stroke Association of Victoria. An invitation to a user needs survey (135 items) for clinicians was circulated via web-based professional forums and national organizations (eg, the Stroke Telehealth Community of Practice Microsoft Teams Channel) and the authors' research networks using Twitter (subsequently rebranded X, X Corp) and LinkedIn (LinkedIn Corp). Following the surveys, 2 rounds of user experience workshops (design and usability testing workshops) were completed with representatives from each end user group (consumers and clinicians). Feedback gathered after each round informed the final design of the digital health program.

RESULTS

Overall, 112 consumers (male individuals: n=63, 56.3%) and 54 clinicians (female individuals: n=43, 80%) responded to the survey; all items were completed by 75.8% (n=85) of consumers and 78% (n=42) of clinicians. Most clinicians (46/49, 94%) indicated the importance of monitoring health and lifestyle measures more frequently than current practice, particularly physical activity, weight, and sleep. Most consumers (87/96, 90%) and clinicians (41/49, 84%) agreed that providing alerts about potential deterioration in an individual's condition were important functions for a digital program. Intention to use a digital program for stroke prevention and discussing the data collected during face-to-face consultations was high (consumers: 79/99, 80%; clinicians 36/42, 86%). In addition, 7 consumers (male individuals: n=5, 71%) and 9 clinicians (female individuals: n=6, 67%) took part in the user experience workshops. Participants endorsed using a digital health program to help consumers manage stroke or TIA and discussed preferred functions and health measures in a digital solution for secondary prevention of stroke. They also noted the need for a mobile app that is easy to use. Clinician feedback highlighted the need for a customizable clinician portal that captures individual consumer goals.

CONCLUSIONS

Following an iterative co-design process, supported by evidence from user needs surveys and user experience workshops, a consumer-facing app that integrates wearable activity trackers and a clinician web portal were designed and developed to support secondary prevention of stroke. Feasibility testing is currently in progress to assess acceptability and use.

Clinical Effectiveness and Utilisation of Cardiac Rehabilitation After Hospital Discharge: Data Linkage Analysis of 84,064 Eligible Discharged Patients (2016-2021)

BACKGROUND

Despite the highest levels of evidence on cardiac rehabilitation (CR) effectiveness, its translation into practice is compromised by low participation.

AIM

This study aimed to investigate CR utilisation and effectiveness in South Australia.

METHODS

This retrospective cohort study used data linkage of clinical and administrative databases from 2016 to 2021 to assess the association between CR utilisation (no CR received, commenced without completing, or completed) and the composite primary outcome (mortality/cardiovascular re-admissions within 12 months after discharge). Cox survival models were adjusted for sociodemographic and clinical data and applied to a population balanced by inverse probability weighting. Associations with non-completion were assessed by logistic regression.

RESULTS

Among 84,064 eligible participants, 74,189 did not receive CR, with 26,833 of the 84,064 (31.9%) participants referred. Of these, 9,875 (36.8%) commenced CR, and 7,681 of the 9,875 (77.8%) completed CR. Median waiting time from discharge to commencement was 40 days (interquartile range, 23-79 days). Female sex (odds ratio [OR] 1.12; 95% CI 1.01-1.24; p=0.024), depression (OR 1.17; 95% CI 1.05-1.30; p=0.002), and waiting time >28 days (OR 1.15; 95% CI 1.05-1.26; p=0.005) were associated with higher odds of non-completion, whereas enrolment in a telehealth program (OR 0.35; 95% CI 0.31-0.40; p<0.001) was associated with lower odds of non-completion. Completing CR (hazard ratio [HR] 0.62; 95% CI 0.58-0.66; p<0.001) was associated with a lower risk of 12-month mortality/cardiovascular re-admissions. Commencing without completing was also associated with decreased risk (HR 0.81; 95% CI 0.73-0.90; p<0.001), but the effect was lower than for those completing CR (p<0.001).

CONCLUSIONS

Cardiac rehabilitation (CR) attendance is associated with lower all-cause mortality/cardiovascular re-admissions, with CR completion leading to additional benefits. Quality improvement initiatives should include promoting referral, women's participation, access to telehealth, and reduction of waiting times to increase completion.

The Influence of Hybrid Comprehensive Telerehabilitation on Anxiety in Heart Failure Patients: The TELEREH-HF Randomized Clinical Trial

Telerehabilitation for heart failure (HF) patients is beneficial for physical functioning, prognosis, and psychological status. The study aimed at evaluating the influence of hybrid comprehensive telerehabilitation (HCTR) on the level of anxiety in comparison to usual care (UC). The TELEREH-HF study was a multicenter prospective RCT in 850 clinically stable HF participants. Patients underwent clinical examinations, including the assessment of anxiety, at entry and after the 9-week training program (HCTR) or observation (UC). The State-Trait Anxiety Inventory (STAI) was used. 20.3% HCTR and 20.1% UC patients reported high level of anxiety as a state at baseline, with higher STAI results in younger participants (< 63 y.o.) (p = .048 for HCTR; p = .026 for UC). At both stages of the study, patients with lower level of physical capacity (measured by a peak VO2) had shown significantly higher level of anxiety. There were no significant changes in anxiety levels during the 9-week observation for the entire study population, although there were different patterns of change in anxiety (both trait and state) in younger and older groups,with the decrease in younger patients, and the increase-in the older group.Trial registry number NCT02523560 (Clinical Trials.gov), date of registration: August 14, 2015.

The effects of internet-based cognitive behaviour therapy for depression in cardiovascular disease on symptoms of anxiety: a secondary analysis of a randomized trial

AIMS

The aims of this study were to evaluate: (i) the short- and long-term effects of the internet-based cognitive behaviour (iCBT) programme on symptoms of distress and fear disorder in cardiovascular disease (CVD) patients, and (ii) the association between changes in depression and changes in symptoms of distress and fear disorder from baseline to 12-month follow-up.

METHODS AND RESULTS

Secondary analysis of data collected in a randomized controlled study evaluating the effects on depression of an iCBT programme compared to an online discussion forum (ODF) in CVD patients (n = 144). Data were collected at baseline, at post-intervention (9 weeks), and at 6- and 12-month follow-ups.The results showed that symptoms of distress disorder were statistically significantly more reduced in the iCBT group than in the ODF group. For symptoms of the fear disorder, no differences were found except for avoidance, which showed a statistically significant reduction in the iCBT group. The long-term analysis in the iCBT group showed that CAQ total score and fear decreased from baseline to 6- and 12-month follow-ups, respectively. Avoidance and attention both decreased statistically significantly from baseline to post-intervention, but not between post-intervention and 12-month follow-up.

CONCLUSION

The results suggest that the iCBT programme targeted depression in CVD patients successfully reduced symptoms of distress disorder and to a lesser extent symptoms of fear disorder. Change in depression was more strongly associated with a change in distress than a change in fear disorder.

Physical Activity After Heart Surgery: Associations With Psychosocial and Sleep Factors

BACKGROUND

Heart surgery is an effective intervention for managing heart disease, the leading cause of death globally. After surgery, physical activity is key to improving patients' quality of life and decreasing mortality, but patients are frequently physically inactive after heart surgery.

OBJECTIVE

This cross-sectional pilot study aimed to examine how psychosocial and sleep factors influenced physical activity in patients after heart surgery. The mediating role of sleep factors between psychosocial factors and physical activity was also examined.

METHODS

Thirty-three patients who had undergone heart surgery were recruited. Psychosocial and sleep factors and physical activity were measured using an online survey and a wrist-worn ActiGraph for 7 days and nights.

RESULTS

The participants had heart surgery an average of about 7 years previously. They exceeded the recommended 150 minutes per week of moderate-intensity physical activity for Americans; however, 64% of them showed poor sleep quality (Pittsburgh Sleep Quality Index >5). Higher anxiety and depressive symptoms, lower self-efficacy, and greater sleep disturbances were associated with lower physical activity. Moreover, self-efficacy, sleep duration, sleep disturbance, sleep efficiency, and wake after sleep onset were predictors for physical activity. No mediating role of sleep factors was observed between psychosocial factors and physical activity.

CONCLUSIONS

Psychosocial and sleep factors should be considered when developing and implementing physical activity strategies for patients after heart surgery. Researchers should examine the relationships among the study variables with larger samples of postsurgical cardiac patients during different periods after heart surgery.

Anxiety Predicts Worse Cardiorespiratory Fitness Outcomes in Cardiac Rehabilitation for Lower Socioeconomic Status Patients

PURPOSE

The purpose of this study was to show that patients in cardiac rehabilitation (CR) with lower socioeconomic status (SES) have worse clinical profiles and higher rates of psychiatric difficulties and they have lower cardiorespiratory fitness (CRF) improvements from CR than their counterparts with higher SES. Improvement in CRF during CR predicts better long-term health outcomes. Research suggests that higher anxiety impairs CRF in structured exercise regimes and is overrepresented among patients with lower SES. However, no study has determined whether this relationship holds true in CR.

METHODS

This study is a secondary analysis of a randomized controlled trial to improve CR attendance among patients with lower SES. Anxiety (ASEBA ASR; Achenbach System of Empirically Based Assessment, Adult Self Report) and CRF measures (metabolic equivalent tasks [METs peak ]) were collected prior to CR enrollment and 4 mo later. Regression was used to examine the association of anxiety with CRF at 4 mo while controlling for other demographic and clinical characteristics.

RESULTS

Eight-eight participants were included in the analyses, 31% of whom had clinically significant levels of anxiety ( T ≥ 63). Higher anxiety significantly predicted lower exit CRF when controlling for baseline CRF, age, sex, qualifying diagnosis, and number of CR sessions attended ( β =-.05, P = .04). Patients with clinically significant levels of anxiety could be expected to lose >0.65 METs peak in improvement.

CONCLUSIONS

The results from this study suggest that anxiety, which is overrepresented in populations with lower SES, is associated with less CRF improvement across the duration of CR. The effect size was clinically meaningful and calls for future research on addressing psychological factor in CR.

Virtual reality-based cognitive-behavioural therapy for the treatment of anxiety in patients with acute myocardial infarction: a randomised clinical trial

Background

The presence of mental health conditions is pervasive in patients who experienced acute myocardial infarction (AMI), significantly disrupting their recovery. Providing timely and easily accessible psychological interventions using virtual reality-based cognitive-behavioural therapy (VR-CBT) could potentially improve both acute and long-term symptoms affecting their mental health.

Aims

We aim to examine the effectiveness of VR-CBT on anxiety symptoms in patients with AMI who were admitted to the intensive care unit (ICU) during the acute stage of their illness.

Methods

In this single-blind randomised clinical trial, participants with anxiety symptoms who were admitted to the ICU due to AMI were continuously recruited from December 2022 to February 2023. Patients who were Han Chinese aged 18-75 years were randomly assigned (1:1) via block randomisation to either the VR-CBT group to receive VR-CBT in addition to standard mental health support, or the control group to receive standard mental health support only. VR-CBT consisted of four modules and was delivered at the bedside over a 1-week period. Assessments were done at baseline, immediately after treatment and at 3-month follow-up. The intention-to-treat analysis began in June 2023. The primary outcome measure was the changes in anxiety symptoms as assessed by the Hamilton Anxiety Rating Scale (HAM-A).

Results

Among 148 randomised participants, 70 were assigned to the VR-CBT group and 78 to the control group. The 1-week VR-CBT intervention plus standard mental health support significantly reduced the anxiety symptoms compared with standard mental health support alone in terms of HAM-A scores at both post intervention (Cohen's d=-1.27 (95% confidence interval (CI): -1.64 to -0.90, p<0.001) and 3-month follow-up (Cohen's d=-0.37 (95% CI: -0.72 to -0.01, p=0.024). Of the 70 participants who received VR-CBT, 62 (88.6%) completed the entire intervention. Cybersickness was the main reported adverse event (n=5).

Conclusions

Our results indicate that VR-CBT can significantly reduce post-AMI anxiety at the acute stage of the illness; the improvement was maintained at the 3-month follow-up.

Impact of cardiac rehabilitation on pre- and post-operative transcatheter aortic valve replacement prognoses

Transcatheter aortic valve replacement (TAVR) is a relatively new treatment method for aortic stenosis (AS) and has been demonstrated to be suitable for patients with varying risk levels. Indeed, among high-risk patients, TAVR outcomes are comparable to, or even better, than that of the traditional surgical aortic valve replacement (SAVR) method. TAVR outcomes, with respect to post-surgical functional capacity and quality of life, have also been found to be improved, especially when combined with cardiac rehabilitation (CR). CR is a multidisciplinary system, which integrates cardiology with other medical disciplines, such as sports, nutritional, mind-body, and behavioral medicine. It entails the development of appropriate medication, exercise, and diet prescriptions, along with providing psychological support, ensuring the cessation of smoking, and developing risk factor management strategies for cardiovascular disease patients. However, even with CR being able to improve TAVR outcomes and reduce post-surgical mortality rates, it still has largely been underutilized in clinical settings. This article reviews the usage of CR during both pre-and postoperative periods for valvular diseases, and the factors involved in influencing subsequent patient prognoses, thereby providing a direction for subsequent research and clinical applications.

The role of daily adjustment disorder, depression and anxiety symptoms for the physical activity of cardiac patients

BACKGROUND

Physical activity (PA) is crucial in the treatment of cardiac disease. There is a high prevalence of stress-response and affective disorders among cardiac patients, which might be negatively associated with their PA. This study aimed at investigating daily differential associations of International Classification of Diseases (ICD)-11 adjustment disorder, depression and anxiety symptoms with PA and sedentary behaviour (SB) during and right after inpatient cardiac rehabilitation.

METHODS

The sample included N = 129 inpatients in cardiac rehabilitation, Mage = 62.2, s.d.age = 11.3, 84.5% male, n = 2845 days. Adjustment disorder, depression and anxiety symptoms were measured daily during the last 7 days of rehabilitation and for 3 weeks after discharge. Moderate-to-vigorous PA (MVPA), light PA (LPA) and SB were measured with an accelerometer. Bayesian lagged multilevel regressions including all three symptoms to obtain their unique effects were conducted.

RESULTS

On days with higher adjustment disorder symptoms than usual, patients engaged in less MVPA, and more SB. Patients with overall higher depression symptoms engaged in less MVPA, less LPA and more SB. On days with higher depression symptoms than usual, there was less MVPA and LPA, and more SB. Patients with higher anxiety symptoms engaged in more LPA and less SB.

CONCLUSIONS

Results highlight the necessity to screen for and treat adjustment disorder and depression symptoms during cardiac rehabilitation.

Comorbidity between major depressive disorder and physical diseases: a comprehensive review of epidemiology, mechanisms and management

Populations with common physical diseases - such as cardiovascular diseases, cancer and neurodegenerative disorders - experience substantially higher rates of major depressive disorder (MDD) than the general population. On the other hand, people living with MDD have a greater risk for many physical diseases. This high level of comorbidity is associated with worse outcomes, reduced adherence to treatment, increased mortality, and greater health care utilization and costs. Comorbidity can also result in a range of clinical challenges, such as a more complicated therapeutic alliance, issues pertaining to adaptive health behaviors, drug-drug interactions and adverse events induced by medications used for physical and mental disorders. Potential explanations for the high prevalence of the above comorbidity involve shared genetic and biological pathways. These latter include inflammation, the gut microbiome, mitochondrial function and energy metabolism, hypothalamic-pituitary-adrenal axis dysregulation, and brain structure and function. Furthermore, MDD and physical diseases have in common several antecedents related to social factors (e.g., socioeconomic status), lifestyle variables (e.g., physical activity, diet, sleep), and stressful live events (e.g., childhood trauma). Pharmacotherapies and psychotherapies are effective treatments for comorbid MDD, and the introduction of lifestyle interventions as well as collaborative care models and digital technologies provide promising strategies for improving management. This paper aims to provide a detailed overview of the epidemiology of the comorbidity of MDD and specific physical diseases, including prevalence and bidirectional risk; of shared biological pathways potentially implicated in the pathogenesis of MDD and common physical diseases; of socio-environmental factors that serve as both shared risk and protective factors; and of management of MDD and physical diseases, including prevention and treatment. We conclude with future directions and emerging research related to optimal care of people with comorbid MDD and physical diseases.

Improving mental well-being in psychocardiology-a feasibility trial for a non-blended web application as a brief metacognitive-based intervention in cardiovascular disease patients

Background

Many patients with cardiovascular disease also show a high comorbidity of mental disorders, especially such as anxiety and depression. This is, in turn, associated with a decrease in the quality of life. Psychocardiological treatment options are currently limited. Hence, there is a need for novel and accessible psychological help. Recently, we demonstrated that a brief face-to-face metacognitive therapy (MCT) based intervention is promising in treating anxiety and depression. Here, we aim to translate the face-to-face approach into digital application and explore the feasibility of this approach.

Methods

We translated a validated brief psychocardiological intervention into a novel non-blended web app. The data of 18 patients suffering from various cardiac conditions but without diagnosed mental illness were analyzed after using the web app over a two-week period in a feasibility trial. The aim was whether a non-blended web app based MCT approach is feasible in the group of cardiovascular patients with cardiovascular disease.

Results

Overall, patients were able to use the web app and rated it as satisfactory and beneficial. In addition, there was first indication that using the app improved the cardiac patients' subjectively perceived health and reduced their anxiety. Therefore, the approach seems feasible for a future randomized controlled trial.

Conclusion

Applying a metacognitive-based brief intervention via a non-blended web app seems to show good acceptance and feasibility in a small target group of patients with CVD. Future studies should further develop, improve and validate digital psychotherapy approaches, especially in patient groups with a lack of access to standard psychotherapeutic care.

Feasibility of Integrating MEditatioN inTO heaRt Disease (the MENTOR Study): A Phase II Randomized Controlled Trial

BACKGROUND

Comorbid depression and/or anxiety symptoms occur in 25% of patients attending cardiac rehabilitation (CR) programs and are associated with poorer prognosis. There is a need to evaluate psychological interventions, including meditation, that have potential to improve psychological health in CR programs.

AIMS

The aim of this study was to determine the feasibility and acceptability of integrating a meditation intervention into an existing Australian CR program for the reduction of depression and anxiety symptoms.

METHODS

This was a mixed-methods feasibility randomized controlled trial. Thirty-one patients with CVD and, at a minimum, mild depression and/or anxiety symptoms were randomized to meditation and standard CR or to standard CR alone. A 16-minute guided group meditation was delivered face-to-face once a week for 6 weeks, with daily self-guided meditation practice between sessions. Feasibility outcomes included screening, recruitment, and retention. Semistructured interviews of patients' (n = 10) and health professionals' (n = 18) perspectives of intervention participation and delivery were undertaken to assess acceptability. Between-group differences in depression, anxiety, stress, self-efficacy for mindfulness, and health status at 6 and 12 weeks were also assessed.

RESULTS AND CONCLUSION

Meditation was considered feasible, with 83% (12/15) of the intervention group completing an average of 3.13 (SD, 2.56) out of 6 group meditation sessions and 5.28 (SD, 8.50) self-guided sessions. Meditation was considered acceptable by patients, clinicians, and health managers. Between-group differences in the number of CR sessions completed favored the intervention group in per-protocol analyses (intervention group vs control group, 12 vs 9 sessions; P = .014), which suggests that meditation may be useful to improve patients' adherence to exercise-based CR program.

Associations of emotional social support, depressive symptoms, chronic stress, and anxiety with hard cardiovascular disease events in the United States: the multi-ethnic study of atherosclerosis (MESA)

BACKGROUND

Cardiovascular diseases (CVDs) are a major cause of morbidity and mortality around the globe and psychosocial factors are not sufficiently understood.

AIM

In the current study, we aimed to evaluate the role of different psychosocial factors including depressive symptoms, chronic stress, anxiety, and emotional social support (ESS) on the incidence of hard CVD (HCVD).

METHODS

We examined the association of psychosocial factors and HCVD incidence amongst 6,779 participants in the Multi-Ethnic Study of Atherosclerosis (MESA). Using physician reviewers' adjudication of CVD events incident, depressive symptoms, chronic stress, anxiety, emotional social support scores were measured by validated scales. We used Cox proportional Hazards (PH) models with psychosocial factors in several of the following approaches: (1) Continuous; (2) categorical; and (3) spline approach. No violation of the PH was found. The model with the lowest AIC value was chosen.

RESULTS

Over an 8.46-year median follow-up period, 370 participants experienced HCVD. There was not a statistically significant association between anxiety and HCVD (95%CI) for the highest versus the lowest category [HR = 1.51 (0.80-2.86)]. Each one point higher score for chronic stress (HR, 1.18; 95% CI, 1.08-1.29) and depressive symptoms (HR, 1.02; 95% CI, 1.01-1.03) was associated with a higher risk of HCVD in separate models. In contrary, emotional social support (HR, 0.98; 95% CI, 0.96-0.99) was linked with a lower risk of HCVD.

CONCLUSIONS

Higher levels of chronic stress is associated with greater risk of incident HCVD whereas ESS has a protective association.

Factors associated with new-onset depressive symptoms in patients starting cardiac rehabilitation: Pre-COVID-19 and COVID-19 period comparison

OBJECTIVE

We aim to: 1) investigate whether starting cardiac rehabilitation (CR) during the COVID-19 period was influential on new-onset depressive symptoms, 2) examine the relationship between sociodemographic and medical factors with the new-onset of depressive symptoms before and during the COVID-19 period in UK patients commencing CR.

METHODS

The national audit of cardiac rehabilitation (NACR) data were used and the two years of data before COVID-19 and during COVID-19 were analysed (Feb,2018 - Nov,2021). Hospital Anxiety and Depression Scale measurement was used to assess depressive symptoms. Bivariate analysis and logistic regression were conducted to examine the influence of the COVID-19 period on new-onset depressive symptoms and the patient characteristics associated with it.

RESULTS

71055 patients screened for new-onset depressive symptoms were included in the analysis. Based on multivariate analysis, patients commencing CR during COVID-19 were 8% more likely to have new onset depressive symptoms compared to patients commencing before COVID-19. Smoking (OR: 1.26, 95%CI: 1.11, 1.43), physical inactivity (OR: 1.86, 95%CI: 1.74, 1.98), high anxiety (OR: 1.45, 95%CI: 1.44, 1.46), being male (OR: 1.21, 95%CI: 1.12, 1.30), single (OR: 1.25, 95%CI: 1.16, 1.35), having comorbidities of arthritis, diabetes, chronic bronchitis, emphysema, claudication (OR range: 1.19 to 1.60), receiving CABG treatment (OR: 1.47, 95%CI: 1.25, 1.73), and having heart failure (OR: 1.33, 95%CI: 1.19, 1.48) were the factors associated with having new-onset depressive symptoms at the start of CR.

CONCLUSION

Our findings have shown that starting CR during the COVID-19 period was associated with increased odds of having new-onset depressive symptoms.

Unmet Needs for Cardiac Rehabilitation in Africa: A Perennial Gap in the Management of Individuals with Cardiac Diseases

Cardiac rehabilitation (CR) is a standard model of care, and an established component of comprehensive care that has been proven to reduce mortality and morbidity in patients with cardiac diseases. International clinical practice guidelines routinely recommend that cardiac patients participate in CR programs for comprehensive secondary prevention. However, there is scant guidance on how to deliver these programs in low-resourced settings. This dearth of clinical practice guidelines may be an indication of low emphasis placed on CR as a component of cardiac health services in low-income countries, especially in Africa. Indeed, CR programs are almost non-existent in Africa despite the unmet need for CR in patients with ischemic heart disease in Africa reported to be about one million. This figure represents the highest unmet need of any World Health Organization region, and is colossal given the projected accelerated increases in incidence of cardiovascular diseases (CVD) in the region. This narrative review explored the availability of CR programs, potential barriers to CR and strategies that can mitigate such barriers in Africa.

Anxiety and depression are associated with poor outcomes in open elbow arthrolysis

BACKGROUND

Open elbow arthrolysis (OEA) is an established treatment for posttraumatic elbow stiffness (PTES); however, its efficacy is debatable for some patients. Poor surgical outcomes have been associated with anxiety and depression in other orthopedic conditions, but no studies have examined this association in OEA. In this study, we aimed to determine whether a high preoperative anxiety and depression score is associated with a worse functional outcome in OEA for PTES.

METHODS

A retrospective review of prospectively collected data was carried out in patients undergoing OEA between April 2021 and March 2022. Mental state evaluated by Hospital Anxiety and Depression Scale (HADS), subjective elbow function valued by Disabilities of the Arm, Shoulder, and Hand (DASH) score, objective elbow function valued by Mayo Elbow Performance Score (MEPS), pain score measured by visual analog scale (VAS) and the flexion-extension range of motion (ROM) of the affected elbow were collected before and after surgery in outpatient clinic follow-up at 3 months and 6 months. Patient satisfaction was only recorded 6 months postoperatively. All patients were divided into 2 groups based on the preoperative HADS score for analysis: Group A was the nonanxiety-depression group, and Group B was the anxiety-depression group.

RESULTS

A total of 49 patients were included. Both groups improved in DASH, MEPS and ROM at 3 months and at 6 months. The HADS score in Group B decreased significantly at 6 months, showing that the mental state of patients in Group B improved after surgery. Group A had a lower DASH at 3 months and 6 months, larger 6-month ROM and higher satisfaction rate than Group B. Comparing the differences between preoperative and postoperative measurements, Group A improved more in ROM at 6 months. There was no significant difference in other outcome measures between the two groups.

CONCLUSIONS

OEA is a safe and effective treatment for PTES, and can achieve good clinical outcomes in the short-term follow-up, regardless of whether the patients suffer from anxiety or depression. Patients with a HADS score ≥11 before OEA, however, have worse outcomes than those with a HADS score <11.

Sex and age as predictors of health-related quality of life change in Phase II cardiac rehabilitation

AIMS

Cardiac rehabilitation (CR) not only improves cardiovascular outcomes, but also health-related quality of life (HRQOL). Unfortunately, CR is still underutilized, especially among women and older patients. Aim of this study was to highlight age- and sex-specific effects of inpatient CR on HRQOL.

METHODS AND RESULTS

From 2012 to 2018, 18 459 patients were prospectively assessed in six Swiss CR clinics. Of these, we retrospectively analysed a final sample of 8286 patients with a mean (standard deviation) age of 67.8 (11.3) in men and 72.2 (11.3) in women. HRQOL was measured at CR entry and discharge. In multivariable analyses, sex- and age-specific changes in HRQOL throughout CR were estimated, adjusting for baseline HRQOL and clinical characteristics. Participants of both sexes improved significantly (P < 0.001) in all domains of HRQOL during CR. Women reported significantly lower social (P < 0.001) and emotional (P < 0.001) HRQOL than men at CR entry. Female sex predicted greater improvement in social (F = 19.63, P < 0.001), emotional (F = 27.814, P < 0.001), and physical HRQOL (F = 20.473, P < 0.001). In a subgroup of n = 2632 elderly patients (>75 years), female sex predicted greater changes in emotional (F = 15.738, P < 0.001) and physical (F = 6.295, P = 0.012), but not in social HRQOL.

CONCLUSION

Women report poorer HRQOL at CR entry compared with men, but in turn particularly benefit from CR in this regard. Our results indicate that sex- and age-specific needs of patients should be considered.

Caregiver Distress and Coronary Artery Disease: Prevalence, Risk, Outcomes, and Management

PURPOSE OF REVIEW

Caregivers of patients with coronary artery disease (CAD) are integral to the health care system and contribute substantially to patients' management. The purpose of this review is to provide a narrative synthesis of existing research on caregiving for patients who experienced an acute coronary syndrome (MI/unstable angina) and/or coronary revascularization (PCI/CABG).

RECENT FINDINGS

Thirty-one articles are included in this review. Overall, caregiver distress is low to moderate, ranging from 6 to 67% of caregivers, and seems to dissipate over time for most caregivers. Interventions have demonstrated success in reducing the distress of caregivers of patients with CAD. Due to the heterogeneity in study samples, measurements used, and timing of assessments and programming, these results are far from definitive. Although evidence is accumulating, further advancement in caregiving science and clinical care is required to adequately understand and respond to the needs of caregivers throughout the patient's illness trajectory.

Role of frailty on cardiac rehabilitation in hospitalized older patients

BACKGROUND

Cardiovascular diseases are the leading cause of mortality, morbidity, and disability in the world, especially in the older adults. A relevant proportion of patients admitted to Cardiac Rehabilitation (CR) may suffer from frailty, a complex geriatric syndrome with multifactorial aetiology.

AIMS

The hypothesis underlying the study is that frailty complicates the management of older patients undergoing CR. The main objective is, therefore, to determine the relationship between frailty and CR outcomes in hospitalized older adults.

METHODS

The participants have been recruited among patients aged ≥ 65 years admitted at the hospital for CR. A Comprehensive Geriatric Assessment (CGA)-based Frailty Index (FI) was created following a standard procedure. The outcome was measured as the ratio between 6-min walk test (6MWT) distance at the end of CR and normal predicted values for a healthy adult of same age and gender, according to reference equations.

RESULTS

The study population consisted of 559 elderly patients, 387 males (69.2%), with age of 72 (69-76) years. The most frequent diagnosis at admission was ischaemic heart disease (231, 41.5%) and overall 6MWT ratio was 0.62 ± 0.21. At the multivariable regression analysis, gender, diagnosis and FI were significantly and independently associated with 6MWT ratio (p ≤ 0.0001, p ≤ 0.001 and p ≤ 0.0001, respectively), while no significant association emerged for age.

CONCLUSION

FI resulted independently correlated to 6MWT ratio in a population of older patients undergoing in-hospital CR programs. Frailty is a multifactorial geriatric syndrome whose assessment is essential for prognostic evaluation of older patients, also in CR clinical setting.

Health professionals' perspectives of integrating meditation into cardiovascular care: A descriptive qualitative study

Preliminary research suggests that meditation may provide benefits in psychological health and well-being in people with cardiovascular disease (CVD). However, little is known about health professionals' perceptions of the barriers and facilitators to integrating meditation into CVD. A descriptive qualitative study design with semi-structured interviews was used to explore the acceptability of integrating meditation into outpatient CVD programs and the organisational factors that may affect its integration. Clinicians were recruited through purposive and snowball sampling. E-mail addresses were obtained from publicly listed profiles of cardiovascular and relevant health organisations. Interview questions included perspectives of organising or delivering meditation within a health setting, format of meditation delivery, organisational or other factors that facilitate or present barriers to integrating meditation into clinical practice, and perceived risks associated with integrating meditation in clinical settings. Verbatim transcripts were thematically analysed using an inductive approach and the Braun and Clarke (2006) method to identify themes within barriers and facilitators to implementation. Eighteen predominately female (61%) senior nursing and medical professionals (61%), as well as health managers (17%), psychologists (11%) and allied health professionals (11%), aged 40-60 years were interviewed between 18 May 2017 and 29 March 2018 in Australia via telephone, or face-to-face at a university or the participants' workplace. Three key themes were identified including: enhancing awareness of meditation within a biomedical model of care, building the evidence for meditation in CVD and finding an organisational fit for meditation in cardiovascular care. Meditation was perceived to sit outside the existing health service structure, which prioritised the delivery of medical care. Health professionals perceived that some physicians did not recognise the potential for meditation to improve cardiovascular outcomes while others acknowledged meditation's positive benefits as a safe, low-cost strategy. The benefits of meditation were perceived as subjective, based on preliminary evidence. Health professionals perceived that aligning meditation with health organisational objectives and integrating meditation into outpatient cardiac rehabilitation and community-based secondary prevention pathways is needed. A fully powered clinical trial is required to strengthen the evidence regarding the role of meditation for psychological health in CVD. Generating clinician engagement and support is necessary to enhance awareness of meditation's use in cardiovascular secondary prevention.

Health Status Stability of Patients in a Medical Rehabilitation Program: What Are the Roles of Time, Physical Fitness Level, and Self-efficacy?

BACKGROUND

Individuals' physical and mental health, as well as their chances of returning to work after their ability to work is damaged, can be addressed by medical rehabilitation.

AIM

This study investigated the developmental trends of mental and physical health among patients in medical rehabilitation and the roles of self-efficacy and physical fitness in the development of mental and physical health.

DESIGN

A longitudinal design that included four time-point measurements across 15 months.

SETTING

A medical rehabilitation center in Germany.

POPULATION

Participants included 201 patients who were recruited from a medical rehabilitation center.

METHODS

To objectively measure physical fitness (lung functioning), oxygen reabsorption at anaerobic threshold (VO2AT) was used, along with several self-report scales.

RESULTS

We found a nonlinear change in mental health among medical rehabilitation patients. The results underscored the importance of medical rehabilitation for patients' mental health over time. In addition, patients' physical health was stable over time. The initial level of physical fitness (VO2AT) positively predicted their mental health and kept the trend more stable. Self-efficacy appeared to have a positive relationship with mental health after rehabilitation treatment.

CONCLUSIONS

This study revealed a nonlinear change in mental health among medical rehabilitation patients. Self-efficacy was positively related to mental health, and the initial level of physical fitness positively predicted the level of mental health after rehabilitation treatment.

CLINICAL REHABILITATION

More attention could be given to physical capacity and self-efficacy for improving and maintaining rehabilitants' mental health.

Levels of depressive symptoms in cardiac patients attending cardiac rehabilitation with a history of depression: pre Covid-19 and Covid-19 period comparison

Background

The large-scale changes in cardiac rehabilitation (CR) programme delivery in response to COVID-19 has led to diminished provision. The influence of these service changes on the depression symptoms of patients in CR programmes is unknown. Our study investigated the extent of depressive symptoms prior to and during the COVID-19 periods in patients with a previous history of depression at the start of CR.

Methods

Use of Registry routine practice data, National Audit of Cardiac Rehabilitation (NACR), from COVID-19 period Feb 2020 and Jan 2021, as well as pre COVID-19 period Feb 2019 and Jan 2020, was extracted. Depressive symptoms were defined according to Hospital Anxiety and Depression Score ≥ 8. Chi-square tests and independent samples t-tests were used to investigate baseline characteristics. Additionally, a binary logistic regression to examine the factors associated with high levels of depressive symptoms.

Results

In total 3661 patients with a history of depression were included in the analysis. Patients attending CR during COVID-19 were found to be 11% more likely to have high levels of acute depressive symptoms compared to patients attending CR prior to COVID-19. Physical inactivity, increased anxiety, a higher total number of comorbidities, increased weight, and living in the most deprived areas were statistically significant factors associated with high levels of acute depressive symptoms at the start of CR following multivariate adjustments.

Conclusion

Our research suggests that following a cardiac event patients with prior history of depression have high levels of acute depressive symptoms at CR baseline assessment. This finding exists in both the pre Covid-19 and Covid-19 periods in patients with a history of depression.

Demographics and risk factors that influence the prevalence of depression in patients attending cardiac rehabilitation

Depression has been associated with adverse outcomes in patients with cardiac disease. Data on its prevalence and the factors influencing it are limited in the cardiac rehabilitation program (CRP) setting. To elucidate the prevalence of and the factors that influence depression in patients attending CRP. Patients attending the CRP from 2003 to 2016 were included in the study. All patients had a Beck Depression Inventory-II (BDI-II) performed prior to commencement in CRP and were followed longitudinally. The BDI-II for the 4989 patients were as follows: 0 to 13 (normal) = 3623 (72%); 14 to 19 (mild depression) = 982 (20%); 20 to 28 (moderate depression) = 299 (6%); 29 to 63 (severe depression) = 85 (2%). The BDI-II (mean ± SEM) for males (mean age: 60.8 ± 0.1 years) and females (mean age: 63.4 ± 0.3 years, P < .001) were 7.0 ± 0.1 and 8.5 ± 0.2 (P < .001), respectively. Elevated BDI-II scores (14-63) were more common in type 1 (41.1%) and type 2 (30.5%) diabetics than nondiabetics (25.7%). Similarly, elevated scores were more common in smokers (36.1%) than never-smokers (24.7%). The BDI-II scores for Caucasians, South Asians, and East Asians were 7.3 ± 0.1, 8.0 ± 0.3, and 7.0 ± 0.3 respectively (P = .01 for CA vs SA by 1-way ANOVA and least significant difference test). The prevalence of depression is high in patients attending CRP affecting 28% of the population. BDI-II is a simple validated screening tool that can be applied to patients attending CRP. Diabetics, current smokers, and South Asians all had a higher prevalence of depression.

The patient education strategy "learning and coping" improves adherence to cardiac rehabilitation in primary healthcare settings: a pragmatic cluster-controlled trial

Background

Adherence and completion of programmes in educational and physical exercise sessions is essential in cardiac rehabilitation (CR) to obtain the known benefits on morbidity, mortality, risk factors, lifestyle, and quality of life. The patient education strategy “Learning and Coping” (LC) has been reported to positively impact adherence and completion in a hospital setting. It is unknown if LC has impact on adherence in primary healthcare settings, and whether LC improves self-management. The aim of this pragmatic primary healthcare-based study was to examine whether patients attending CR based on LC had a better adherence to patient education and physical exercise, higher program completion rate, and better self-management compared to patients attending CR based on a consultation program Empowerment, Motivation and Medical Adherence (EMMA).

Method

A pragmatic cluster-controlled trial of two types of patient education LC and EMMA including ten primary healthcare settings and 514 patients (LC, n = 266; EMMA, n = 248) diagnosed with ischaemic heart disease discharged from hospital and referred to CR between August 1, 2018 and July 31, 2019. Adherence was defined as participation in ≥ 75% of provided sessions. Completion was defined as patients attended the final interview at the end of the 12-weeks programme. Patient Activation Measure (PAM) was used to obtain information on a person's knowledge, skills and confidence for self-management. PAM questionnaire was completed at baseline and 12-weeks follow-up. Multiple and Linear regression analyses adjusted for potential confounder variables and cluster effect were performed.

Result

Patients who followed CR based on LC had a higher adherence rate to educational and physical exercise sessions compared to patients who followed CR based on EMMA (p < 0.01). High-level of completion was found at the end of CR with no statistically significant between clusters (78.9% vs. 78.2%, p > 0.05). At 12-weeks, there was no statistical differences in PAM-score between clusters (p > 0.05).

Conclusion

This study indicates that the LC positively impacts adherence in CR compared to EMMA. We found non-significant difference in completing CR and in patient self-management between the two types of patient education. Future studies are needed to investigate if the higher adherence rate achieved by LC in primary healthcare settings translates into better health outcomes.

Effectiveness of Family-Centered Empowerment Model on Psychological Improvement of Patients With Myocardial Infarction: A Bayesian Multivariate Approach

Objective

There is a limited understanding of the impact of the family-centered empowerment model (FCEM) on the psychological symptoms in post-myocardial infarction (MI). This study aimed to evaluate the effectiveness of the FCEM on the psychological improvement of patients with MI.

Methods

The present study was a randomized controlled trial (RCT) where patients experienced a standard home cardiac rehabilitation (CR) or CR utilizing the FCEM approach. The empowerment of patients was estimated during nine assessments, such as pre- and post-intervention. Factors, such as quality of life (QoL), state and trait anxiety, and perceived stress, were evaluated. A Bayesian multivariate mixed-effects model was used to simultaneously investigate the effect of the intervention group on study outcomes across the time.

Results

Among all the participants in this study, 24 (34.3%) were women with a total mean ± standard deviation (SD) of 61.40 ± 12.83 and 24.87 ± 3.80 for age and body mass index (BMI). The participants who were in the FCEM group had a significantly higher mean level of perceived stress (β = 28.80), state anxiety (β = 16.20), trait anxiety (β = 3.65), physical (β = 38.54), and mental QoL (β = 42.14). Moreover, the individuals in the FCEM group had a significantly higher mean level of general health (β = 31.64) in the physical dimension of QoL, vitality (β = 15.04), mental role limitation (β = 21.84), and mental health (β = 18.16) in the mental dimension of QoL.

Conclusions

The FCEM can be a valuable treatment mechanism for patients with post-MI to improve their stress, anxiety, and QoL.

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.

Preliminary Efficacy of an Emotion Regulation Intervention on Physical Activity and Depressive and Anxious Symptoms in Individuals in Cardiac Rehabilitation

BACKGROUND

For the 720 000 Americans expected to experience a new acute cardiac event this year, cardiac rehabilitation is an important part of recovery. Symptoms of depression and anxiety undermine recovery efforts, leaving recovering patients at risk for diminished functional capacity and heightened risk of mortality. Poor emotion regulation can worsen symptoms of depression and anxiety and hinder recovery efforts.

OBJECTIVE

The purpose of this randomized controlled trial was to evaluate the early efficacy testing of a theoretically based emotion regulation treatment (Regulating Emotions to Improve Self-management of Nutrition, Exercise, and Stress [RENEwS]) designed to assist survivors of an acute cardiac event in cardiac rehabilitation to optimize recovery.

METHODS

Survivors of an acute cardiac event in cardiac rehabilitation (n = 30, 83% men) were randomized to five 1-hour in-person group sessions of RENEwS or a phone-based attention-control group. Participants completed measures of depression and anxiety symptoms at 3 time points. Moderate to vigorous physical activity (MVPA) was objectively measured for 7 days at each time point using waist-worn actigraphy monitors. Between-group differences were calculated using analysis of variance with Cohen f effect sizes calculated to evaluate initial efficacy.

RESULTS

There was no statistically significant difference in depression, anxiety, or MVPA over time based on group assignment (all P > .05). Compared with attention control participants, in RENEwS participants, preliminary effects showed greater reductions in depression (Cohen f = 0.34) and anxiety (Cohen f = 0.40) symptoms but only modest improvements in MVPA from baseline to 5 months (Cohen f = 0.08).

CONCLUSIONS

Findings show that RENEwS is a promising emotion regulation intervention to enhance cardiac rehabilitation and potentially decrease symptoms of depression and anxiety.

Effectiveness of Intensive Cardiac Rehabilitation in High-Risk Patients with Cardiovascular Disease in Real-World Practice

Structured lifestyle interventions through cardiac rehabilitation (CR) are critical to improving the outcome of patients with cardiovascular disease (CVD) and cardiometabolic risk factors. CR programs' variability in real-world practice may impact CR effects. This study evaluates intensive CR (ICR) and standard CR (SCR) programs for improving cardiometabolic, psychosocial, and clinical outcomes in high-risk CVD patients undergoing guideline-based therapies. Both programs provided lifestyle counseling and the same supervised exercise component. ICR additionally included a specialized plant-based diet, stress management, and social support. Changes in body weight (BW), low-density lipoprotein cholesterol (LDL-C), and exercise capacity (EC) were primary outcomes. A total of 314 patients (101 ICR and 213 SCR, aged 66 ± 13 years, 75% overweight/obese, 90% coronary artery disease, 29% heart failure, 54% non-optimal LDL-C, 43% depressive symptoms) were included. Adherence to ICR was 96% vs. 68% for SCR. Only ICR resulted in a decrease in BW (3.4%), LDL-C (11.3%), other atherogenic lipids, glycated hemoglobin, and systolic blood pressure. Both ICR and SCR increased EC (52.2% and 48.7%, respectively) and improved adiposity indices, diastolic blood pressure, cholesterol intake, depression, and quality of life, but more for ICR. Within 12.6 ± 4.8 months post-CR, major adverse cardiac events were less likely in the ICR than SCR group (11% vs. 17%), especially heart failure hospitalizations (2% vs. 8%). A comprehensive ICR enhanced by a plant-based diet and psychosocial management is feasible and effective for improving the outcomes in high-risk CVD patients in real-world practice.

Patient-Reported Outcomes in Cardiovascular Trials

Patient-reported outcomes (PROs) are reports of a person's health status that provide a global perspective of patient well-being. PROs can be classified into 4 primary domains: global, mental, physical, and social health. In this descriptive review, we focus on how PROs can be used in cardiac clinical trials, with an emphasis on cardiac surgical trials for patients with coronary heart disease and heart failure. We also highlight ongoing challenges and provide specific suggestions and novel opportunities to advance cardiac clinical trials. Current challenges include the long-term measurement of PROs in clinical trials beyond 1 year, inconsistency in the choice of the outcome measures among studies, and the lack of measurement of PROs across multiple domains. Opportunities for advancement include measuring PROs using consumer health informatics tools, including returning information back to participants in formats that they can understand using visualization. Future opportunities include quantifying cohort-specific minimal clinically important differences for PROs.

Intensive group-based cognitive therapy in patients with cardiac disease and psychological distress-a randomized controlled trial protocol

Background

Many patients with coronary artery disease (CAD) and valvular heart disease (VHD) suffer from psychological distress. Such stress is associated with increased morbidity, reduced quality of life and delayed return to work. European guidelines emphasize recognition and intervention, but evidence-based treatment options are limited and perceived as costly. The present study will test the effect of brief, group-based cognitive therapy as an adjunct to usual cardiac rehabilitation in a randomized design.

Methods

A total of 148 patients with CAD and/or VHD after surgical intervention and concomitant psychological distress (defined as HADS anxiety (A) or depression (D) score ≥8) will be randomized to either usual out-patient cardiac rehabilitation (CR) comprising an 8-week multidisciplinary programme or usual care supplemented by five group-based cognitive therapy sessions performed by trained CR nurses. A structured, standardized treatment manual will be used. Patients will be randomized 1:1 at three different sites. Additionally, a non-randomized sub-group of 40 matched patients without signs of psychological distress will be followed to investigate spontaneous variation in HADS. The primary outcome is Hospital Anxiety and Depression Score (HADS). Secondary outcomes are adherence to cardiac rehabilitation (CR), health-related quality of life measured by HeartQoL, time to return to work, adherence to lifestyle interventions and cardiovascular readmissions. Patients are followed up for 12 months.

Discussion

To our knowledge, this is the first randomized controlled trial (RCT) on patients with cardiac disease with an intensive group-based programme of cognitive therapy performed by CR nurses, which makes it affordable and widely implementable. The outcome will elucidate the feasibility and effect of cognitive therapy as an adjunct to CR in patients with post-surgery CAD and/or VHD and psychological distress and could possibly benefit patients with other heart conditions as well. The clinical trial complies with the Declaration of Helsinki. The trial has been approved by The Regional Research Ethics Committee (file number H-16042832) and The Danish Data Protection Agency. The results will be disseminated as original research in peer-reviewed manuscripts.

Depression and anxiety in cardiac rehabilitation: differential associations with changes in exercise capacity and quality of life

BACKGROUND

Cardiac rehabilitation (CR) has been successful in improving exercise capacity (EC) and quality of life (QoL). However, depression and anxiety are highly prevalent among cardiac patients and might represent risk factors for rehabilitation outcomes. The aim of this study was to investigate the role of depression and anxiety as possible independent risk factors for CR outcomes.

METHODS

The study applied a pre-post-design. The sample comprised N = 3'434 cardiac disease patients taking part in a Swiss inpatient CR center. Variables measured at the beginning (T1) and end of rehabilitation (T2) included depression and anxiety (HADS), EC, and QoL (MacNew). A path analysis was conducted.

RESULTS

Depression at T1 had a significant negative relationship with improvements in EC and in all aspects of QoL during rehabilitation. Anxiety at T1 was positively related to improvements in EC and in emotional and physical QoL. Improvements in depression during CR were positively related with improvements in all outcomes. Improvements in anxiety showed no significant association with the outcomes.

CONCLUSION

Depression and anxiety should be screened for during CR. Depression should be treated due to the negative association found with rehabilitation outcomes. Underlying mechanisms of the positive association of anxiety with rehabilitation outcomes need further investigation.

Comparison of Activity and Participation, and Mental and Physical Functions of Immediate Post-Acute and Distant Post-Acute Adults with Chronic Cardiac Conditions

This study compared activity participation, and mental and physical functions of two different groups of adults with chronic cardiac conditions. Eleven participants were assessed at the immediate post-acute stage and 26 participants were at the distant post-acute stage. Participants at distant post-acute were significantly more physically active (p < .001), more activity-limited in cognition-related activities (p = .035) and reported more depressive symptoms than immediate post-acute (p = .046). No significant difference in participation level was found. More attention to functional cognition and depressive symptoms at immediate post-acute and individualized approaches to remove participation barriers in complex activities at distant post-acute are likely needed for adults with chronic cardiac conditions.

The Role of Lifestyle and Cardiovascular Risk Factors in Dropout From an Australian Cardiac Rehabilitation Program. A Longitudinal Cohort Study

BACKGROUND

Cardiac rehabilitation (CR) programs reduce the risk of further cardiac events and improve the ability of people living with cardiovascular disease to manage their symptoms. However, many people who experience a cardiac event do not attend or fail to complete their CR program. Little is known about the characteristics of people who drop out compared to those who complete CR.

AIMS

To identify subgroups of patients attending a cardiac rehabilitation program who are more likely to dropout prior to final assessment by (1) calculating the dropout rate from the program, (2) quantifying the association between dropout and socio-demographic, lifestyle, and cardiovascular risk factors, and (3) identifying independent predictors of dropout.

METHODS

The study population is from a large metropolitan teaching hospital in Sydney, Australia, and consists of all participants consecutively enrolled in an outpatient CR program between 2006 and 2017. Items assessed included diagnoses and co-morbidities, quality of life (SF-36), psychological health (DASS-21), lifestyle factors and physical assessment. Dropout was defined as failure to complete the outpatient CR program and post CR assessment.

RESULTS

Of the 3,350 patients enrolled in the CR program, 784 (23.4%; 95%CI: 22.0-24.9%) dropped out prior to completion. The independent predictors of dropout were smoking (OR 2.4; 95%CI: 1.9-3.0), being separated or divorced (OR 2.0; 95%CI: 1.5-2.6), younger age (<55 years) (OR 1.9; 95%CI: 1.6-2.4), obesity (OR 1.6; 95%CI: 1.3-2.0), diabetes (OR 1.6; 95%CI: 1.3-2.0), sedentary lifestyle (OR 1.3; 95%CI: 1.1-1.6) and depressive symptoms (OR 1.3; 95%CI: 1.1-1.6).

CONCLUSION

To improve the CR program completion rate, clinicians need to consider the impact of socio-demographic, lifestyle, and cardiovascular risk factors on their patients' ability to complete CR. Tailored strategies which target the independent predictors of dropout are required to promote adherence to CR programs and thereby potentially reduce long-term cardiovascular risk.
