Psychometric testing of the caregiver contribution to self-care of coronary heart disease inventory.

BACKGROUND: Caregivers are important contributors to the self-care of patients with coronary heart disease (CHD). AIMS: The aims of this study are to describe the development and psychometric properties of the caregiver contribution to self-care of coronary heart disease inventory (CC-SC-CHDI). METHODS: The CC-SC-CHDI was developed from the patient version of the scale, the Self-care of Coronary Heart Disease Inventory (SC-CHDI) and translated into Italian using forward and backward translation. Baseline data from the HEARTS-IN-DYADS study were used. Confirmatory factor analysis (CFA) was conducted to assess factorial validity; Cronbach's alpha and the model-based internal consistency index were used to test internal consistency reliability, and Pearson's correlation coefficient was used to test convergent validity, by investigating the association between the CC-SC-CHDI and the SC-CHDI scores. RESULTS: We included 131 caregivers (mean age 55 years, 81.2% females, 74% married) of patients affected by CHD (mean age 66 years, 80.2% males, 74% married). The CFA confirmed two factors in the caregiver contribution to self-care maintenance scale ("consulting behaviors" and "autonomous behaviors"), one factor for the CC to self-care monitoring scale, and two factors in the CC to self-care management scale ("consulting behaviors and problem-solving behaviors"). Reliability estimates were adequate for each scale (Cronbach's alpha and model-based internal consistency indexes ranging from 0.73 to 0.90). Significant and positive correlations were observed between CC-SC-CHDI and SC-CHDI scales. CONCLUSION: The CC-SC-CHDI has satisfactory validity and reliability and can be used confidently in clinical settings and research to assess caregiver contributions to CHD self-care.

Sexual experience in patients with coronary heart disease: a descriptive phenomenological study.

Sex is an essential part of life and is a basic demand for human beings. Coronary heart disease can have an impact on patients' sexual lives; however, not much attention has been paid to it in China, and few studies have been conducted on this topic. Therefore, this study used a qualitative approach to understand the sexual experience of patients after the illness, thus laying the foundation for the development of relevant measures. Semi-structured interviews were conducted with 14 patients. Descriptive phenomenological methods were employed to collect data and explore the sexual experience of patients with coronary heart disease. A total of 4 thematic groups, 9 themes, and 23 subthemes were extracted. The four thematic groups were independent and cross-influenced. In these groups, alterations in the sexual experience, including the change in sexual physiology and psychological state, were affected by the lack of knowledge, age, disease, and other factors. Furthermore, the patient's perception of sexuality affected the quality of sexual life after the illness. The sexual experience of patients with coronary heart disease and its influencing factors, such as age, disease factors, and lack of related knowledge, were described. The findings are expected to aid in formulating targeted and personalized intervention measures.

Effectiveness of an Interactive mHealth App (EVITE) in Improving Lifestyle After a Coronary Event: Randomized Controlled Trial.

BACKGROUND: Coronary heart disease is one of the leading causes of mortality worldwide. Secondary prevention is essential, as it reduces the risk of further coronary events. Mobile health (mHealth) technology could become a useful tool to improve lifestyles. OBJECTIVE: This study aimed to evaluate the effect of an mHealth intervention on people with coronary heart disease who received percutaneous coronary intervention. Improvements in lifestyle regarding diet, physical activity, and smoking; level of knowledge of a healthy lifestyle and the control of cardiovascular risk factors (CVRFs); and therapeutic adherence and quality of life were analyzed. METHODS: This was a randomized controlled trial with a parallel group design assigned 1:1 to either an intervention involving a smartphone app (mHealth group) or to standard health care (control group). The app was used for setting aims, the self-monitoring of lifestyle and CVRFs using measurements and records, educating people with access to information on their screens about healthy lifestyles and adhering to treatment, and giving motivation through feedback about achievements and aspects to improve. Both groups were assessed after 9 months. The primary outcome variables were adherence to the Mediterranean diet, frequency of food consumed, patient-reported physical activity, smoking, knowledge of healthy lifestyles and the control of CVRFs, adherence to treatment, quality of life, well-being, and satisfaction. RESULTS: The study analyzed 128 patients, 67 in the mHealth group and 61 in the control group; most were male (92/128, 71.9%), with a mean age of 59.49 (SD 8.97) years. Significant improvements were observed in the mHealth group compared with the control group regarding adherence to the Mediterranean diet (mean 11.83, SD 1.74 points vs mean 10.14, SD 2.02 points; P<.001), frequency of food consumption, patient-reported physical activity (mean 619.14, SD 318.21 min/week vs mean 471.70, SD 261.43 min/week; P=.007), giving up smoking (25/67, 75% vs 11/61, 42%; P=.01), level of knowledge of healthy lifestyles and the control of CVRFs (mean 118.70, SD 2.65 points vs mean 111.25, SD 9.05 points; P<.001), and the physical component of the quality of life 12-item Short Form survey (SF-12; mean 45.80, SD 10.79 points vs mean 41.40, SD 10.78 points; P=.02). Overall satisfaction was higher in the mHealth group (mean 48.22, SD 3.89 vs mean 46.00, SD 4.82 points; P=.002) and app satisfaction and usability were high (mean 44.38, SD 6.18 out of 50 points and mean 95.22, SD 7.37 out of 100). CONCLUSIONS: The EVITE app was effective in improving the lifestyle of patients in terms of adherence to the Mediterranean diet, frequency of healthy food consumption, physical activity, giving up smoking, knowledge of healthy lifestyles and controlling CVRFs, quality of life, and overall satisfaction. The app satisfaction and usability were excellent. TRIAL REGISTRATION: Clinicaltrials.gov NCT04118504; https://clinicaltrials.gov/study/NCT04118504.

Multiple coronary heart diseases are risk factors for mental health disorders: A mendelian randomization study.

BACKGROUND: Previous observational studies have suggested associations between Coronary Heart Disease (CHD) and Mental Health Disorders (MHD). However, the causal nature of these relationships has remained elusive. OBJECTIVE: The purpose of this study is to elucidate the causal relationships between eight distinct types of CHD and six types of MHD using Mendelian randomization (MR) analysis. METHODS: The MR analysis employed a suite of methods including inverse variance-weighted (IVW), MR-Egger, weighted mode, weighted median, and simple mode techniques. To assess heterogeneity, IVW and MR-Egger tests were utilized. MR-Egger regression also served to investigate potential pleiotropy. The stability of IVW results was verified by leave-one-out sensitivity analysis. RESULTS: We analyzed data from over 2,473,005 CHD and 803,801 MHD patients, informed by instrumental variables from large-scale genomic studies on European populations. The analysis revealed a causal increase in the risk of Major Depressive Disorder and Mania associated with Coronary Artery Disease and Myocardial Infarction. Heart Failure was found to causally increase the risk for Bipolar Disorder and Schizophrenia. Atrial Fibrillation and Ischemic Heart Diseases were positively linked to Generalized Anxiety Disorder and Mania, respectively. There was no significant evidence of an association between Hypertensive Heart Disease, Hypertrophic Cardiomyopathy, Pulmonary Heart Disease, and MHD. Reverse MR analysis indicated that MHD do not serve as risk factors for CHD. CONCLUSIONS: The findings suggest that specific types of CHD may act as risk factors for certain MHDs. Consequently, incorporating psychological assessments into the management of patients with CHD could be advantageous.

The overall fractions of coronary heart diseases and depression attributable to multiple dependent psychosocial work factors in Europe.

OBJECTIVES: The literature is nonexistent on the assessment of overall fractions of diseases attributable to multiple dependent psychosocial work factors. The objectives of the study were to calculate the overall fractions of coronary heart diseases (CHD) and depression attributable to multiple dependent psychosocial work factors in 35 European countries. METHODS: We used already published fractions of CHD and depression attributable to each of the following psychosocial work factors: job strain, effort-reward imbalance, job insecurity, long working hours, and workplace bullying. We took all exposures and their correlations into account to calculate overall attributable fractions. Wald tests were performed to test differences in these overall attributable fractions between genders and between countries. RESULTS: The overall fractions of CHD and depression attributable to all studied psychosocial work factors together were found to be 8.1% [95% CI: 2.0-13.9] and 26.3% [95% CI: 16.2-35.5] respectively in the 35 European countries. There was no difference between genders and between countries. CONCLUSION: Our study showed that the overall fractions attributable to all studied psychosocial work factors were substantial especially for depression. These overall attributable fractions may be particularly useful to evaluate the burden and costs attributable to psychosocial work factors, and also to inform policies makers at European level.

The effects of Solution-Focused Brief Therapy on self-care and mental health among older adults at risk of coronary heart disease: A randomized controlled trial.

This study tested the effectiveness of a nursing program developed based on Solution-Focused Brief Therapy (SFBT) in improving self-care skills and mental health among community-dwelling older adults at risk for coronary heart disease (CHD). A total of 120 older adults were randomly assigned to either an SFBT group or a control group. Participants' self-care ability, depressive symptoms, and anxiety at baseline and post-intervention were assessed using the Self-care Ability Scale for the Elderly (SASE), Self-Rating Depression Scale (SDS), and Self-Rating Anxiety Scale (SAS), respectively. The t-test, Mann-Whitney U, and chi-square tests were conducted for group comparisons. After 6 months of intervention, the intervention group had significantly higher self-concept, self-skills, self-care awareness, and health knowledge scores than the baseline and the control group (all P-values < 0.05). The intervention group had significantly lower depression and anxiety scores than the baseline and the control group (all P-values < 0.05). SFBT is effective in improving older adults' self-care and mental health and may be widely applied among older adults to prevent CHD and promote well-being in the future.

Moderating Effect of Sex on the Relationship Between Physical Activity and Quality of Life in Coronary Heart Disease Patients in China.

PURPOSE: The aim of this study was to investigate the moderating effect of sex on the relationship between physical activity (PA) and quality of life (QoL) in Chinese patients with coronary heart disease (CHD) not participating in cardiac rehabilitation. METHODS: Chinese patients with CHD (aged 18-80 yr) were selected 12 mo after discharge from three Hebei Province tertiary hospitals. The International Physical Activity Questionnaire was used to assess PA in metabolic equivalents of energy (METs) and the Chinese Questionnaire of Quality of Life in Patients With Cardiovascular Disease was used to assess QoL. Data were analyzed using Student's t test and the χ 2 test, multivariant and hierarchical regression analysis, and simple slope analysis. RESULTS: Among 1162 patients with CHD studied between July 1 and November 30, 2017, female patients reported poorer QoL and lower total METs in weekly PA compared with male patients. Walking ( ß= .297), moderate-intensity PA ( ß= .165), and vigorous-intensity PA ( ß= .076) positively predicted QoL. Hierarchical regression analysis showed that sex moderates the relationship between walking ( ß= .195) and moderate-intensity PA ( ß= .164) and QoL, but not between vigorous-intensity PA ( ß= -.127) and QoL. Simple slope analysis revealed the standardized coefficients of walking on QoL were 0.397 (female t  = 8.210) and 0.338 (male t = 10.142); the standardized coefficients of moderate-intensity PA on QoL were 0.346 (female, t  = 7.000) and 0.175 (male, t = 5.033). CONCLUSIONS: Sex moderated the relationship between PA and QoL among patients with CHD in China. There was a greater difference in QoL for female patients reporting higher time versus those with lower time for both walking and moderate-intensity PA than for male patients.

Depression and anxiety symptom network structure among patients with coronary heart disease and association with quality of life: protocol for a multicentre cross-sectional and prospective longitudinal study.

BACKGROUND: Anxiety and depression are critical mental health problems among persons with coronary heart disease (CHD). The range of symptoms is an important stressor for adverse cardiovascular events, and these symptoms can be involved in various ways during the course of CHD. However, the characteristics and mechanisms of comorbidity between the two mental states from the viewpoint of symptom interactions in patients with CHD remain unclear. Therefore, we aim to apply a symptom-oriented approach to identify core and bridge symptoms between anxiety and depression in a population with CHD and to identify differences in network structure over time and symptomatic link profiles. METHODS AND ANALYSIS: We designed a multicentre, cross-sectional, longitudinal study of anxiety and depression symptoms among patients with CHD. We will evaluate degrees of symptoms using the Generalized Anxiety Disorder Scale, the Patient Health Questionnaire and the WHO Quality of Life-Brief version. Patients will be followed up for 1, 3 and 6 months after baseline measurements. We will analyse and interpret network structures using R software and its packages. The primary outcomes of interest will include centrality, bridge connections, estimates, differences in network structures and profiles of changes over time. The secondary outcome measures will be the stability and accuracy of the network. By combining cross-sectional and longitudinal analyses, this study should elucidate the central and potential causative pathways among anxiety and depression symptom networks as well as their temporal stability in patients with CHD. ETHICS AND DISSEMINATION: The project conforms to the ethical principles enshrined in the Declaration of Helsinki (2013 amendment) and all local ethical guidelines. The ethics committee at the University of South China approved the study (Approval ID: 2023-USC-HL-414). The findings will be published and presented at conferences for widespread dissemination. TRIAL REGISTRATION NUMBER: ChiCTR2300075813.

Predicting physical activity and quality of life in coronary heart disease patients: An 18-month path analysis of motivational and emotional factors.

OBJECTIVE: Investigating factors that promote cardiovascular health outcomes is essential for secondary prevention. In a sample of coronary heart disease patients, we examined the direct and indirect effects of selected psychological factors on physical activity behavior and health-related quality of life (HRQoL) over 18 months. METHOD: Patient-reported data were collected over three time points. Through structured equation modeling, a longitudinal path analysis was conducted to estimate the indirect effects of baseline HRQoL and cardiac self-efficacy on reported physical activity behavior and HRQoL (evaluated at 18 months) through the mediation of anxiety and depression symptoms, patients' reported intention to change the behavior, and emotions regulation strategies (evaluated at 9 months). RESULTS: A total of 410 patients were included. Significant indirect effects of baseline HRQoL (ß = .05, 95% CI [-0.001, 0.111]) and cardiac self-efficacy (ß = .105, 95% CI [0.06, 0.16]) on physical activity behavior were found, with anxiety symptoms and emotions regulation strategies as significant mediators. Additionally, the mediation of reported intention in the association between cardiac self-efficacy and physical activity levels was estimated. At the final follow-up, we also found a significant direct association between physical activity behavior and HRQoL (ß = .12, p < .01), which was indirectly impacted by baseline HRQoL (ß = .006, 95% CI [0.000, 0.017]) and cardiac self-efficacy (ß = .012, 95% CI [0.003, 0.027]). CONCLUSIONS: This study underlines the significance of addressing stress management, anxiety symptoms reduction, and cardiac self-efficacy enhancement when targeting better cardiovascular health outcomes. Identifying cardiovascular risk profiles based on these findings may benefit future clinical practice and further inform secondary prevention policy guidelines.

An Educational Intervention for Coronary Heart Disease Patients With Type D Personality: A Randomized Controlled Trial.

BACKGROUND: Type D personality, a newly specified personality type defined as the interaction of high levels of negative affectivity and social inhibition, is associated with poor health outcomes. Few interventional studies have been performed to improve health outcomes in this subpopulation. PURPOSE: This study was developed to examine the effects of an educational intervention on psychological health, health-promoting behaviors, and quality of life in coronary heart disease (CHD) patients with type D personality in China. METHODS: A randomized controlled trial was adopted. One hundred twenty-eight patients with CHD and type D personality were randomly assigned. The intervention group received the 12-week educational intervention in addition to usual care, whereas the control group received usual care only. Data on anxiety and depression, health-promoting behaviors, and quality of life were collected at baseline and at 1 and 3 months after enrollment. After controlling for the covariates, the generalized estimating equation model was used to examine the intervention effects. RESULTS: The mean age of the participants was 61.02 years, and more than 70% were male. Results of the generalized estimating equation analysis showed significantly greater improvements in anxiety, depression, and health-promoting behaviors in the intervention group than in the control group. In addition, quality of life, the domains of angina limitation, angina stability, and treatment satisfaction were found to have improved more significantly in the intervention group than the control group, whereas the posttest changes in angina frequency and disease perception were found to be similar in both groups. CONCLUSIONS/IMPLICATIONS FOR PRACTICE: The educational intervention was shown to be effective in improving psychological health, health-promoting behaviors, and certain domains of quality of life in patients with CHD and type D personality. Nurses should identify patients with this personality type and provide tailored care to improve their health outcomes in clinical practice.

The article concludes with recommendations for future research and clinical practice.

Effects of empowerment education on patients after percutaneous coronary intervention: A meta-analysis and systematic review.

BACKGROUND: Empowerment education is a new nursing education model with great significance in the process of chronic disease rehabilitation, and a number of studies have found that it has good benefits for patients after percutaneous coronary intervention (PCI). But there is no meta-analysis on how empowerment education influence the life of patients after PCI. AIMS: Our study intends to evaluate the impact of empowerment education on the quality of life, cognitive level, anxiety and depression level of patients after PCI. DESIGN: Systematic review and meta-analysis, following PRISMA guidelines. METHODS: RevMan5.4 software and R software were used for statistical analysis. Mean difference or standard mean difference was used as effect analysis statistic for continuous variables with 95% confidence intervals. RESULTS: Six studies met the inclusion criteria, including 641 patients. The Exercise of Self-Care Agency Scale score of the experimental group was higher than that of the control group, with statistically significant difference. Empowerment education could increase the knowledge of coronary heart disease in patients after PCI, but the difference was not statistically significant. CONCLUSION: Significant effects of empowerment have been found in improving patients' quality of life and self-care ability. Empowerment education could be a safe exercise option in PCI rehabilitation. However, the effect of empowerment on cognitive level for coronary heart disease and the depression needs to carry out more large-sample, multi-center clinical trials. PATIENT OR PUBLIC CONTRIBUTION: A data-analysis researcher and 3 clinicians are responsible for the writing, and no patients participated in the writing of this paper.

Theory-based nursing interventions in adults with coronary heart disease: A systematic review and meta-analysis of randomized controlled trials.

PURPOSE: This systematic review and meta-analysis aimed to synthesize the outcomes of theory-based nursing interventions for coronary heart disease management. DESIGN AND METHODS: Web of Science, Scopus, Science Direct, and PubMed databases were electronically searched from January 2013 to August 2021. The Preferred Reporting Item for Systematic Reviews and Meta-analyses statement guidelines was followed for this meta-analysis. Randomized controlled trials on patients with coronary heart disease, using a theory-based nursing intervention were eligible. Methodological quality was examined by two authors using the Modified Jadad Scale. Based on the heterogeneity test, the results were analyzed using a pool of data with 95% confidence intervals, p-values, and fixed or random-effect models (PROSPERO registration number X). FINDINGS: A total of 1030 studies were initially retrieved, and 8 randomized controlled trials were eventually included in the meta-analysis after screening. The big majority (81.3%) of participants were males, and the mean age was 54.8 (SD = 8.7) years. This meta-analysis found theory-based nursing interventions had no significant effect on blood lipid profile, blood pressure, and healthy lifestyle. However, these interventions significantly reduced fasting blood glucose, and body mass index and improved the physical and psychological domains of quality of life. CONCLUSIONS: The evidence from this meta-analysis reveals that theory-based nursing interventions have a positive effect on fasting blood glucose, body mass index, and quality of life. However, their effects on blood lipid profile, blood pressure, and a healthy lifestyle are inconclusive. The results of this metanalysis are largely based on a few trials and were limited in terms of the number of outcomes. Conducting well-designed randomized controlled trials with adequate power is needed to make a firm conclusion on the influence of theory-based nursing interventions on patient outcomes in the CHD population. CLINICAL RELEVANCE: Considering the high mortality and morbidity of coronary heart disease, nurses may play a significant role in coronary heart disease management by providing interventions that are based on a certain theoretical framework. This meta-analysis provides insights into the implementation of theory-based nursing interventions in heart attack survivors or those newly diagnosed with coronary heart disease led by nurses and lasting longer than 6 months in coronary heart disease. In addition, future studies should consider enhancing the content of training programs for a healthy lifestyle within the theory-based nursing interventions and compare the effects of these interventions on acute and chronic coronary syndromes.

The psychological consequences of living with coronary heart disease: Are patients' psychological needs served? A mixed-method study in Germany.

INTRODUCTION: This mixed-method study explores psychological needs, access and barriers in coronary heart disease (CHD) patients with and without mental health issues (MHI) within the German healthcare system. METHODS: This study was conducted in three different healthcare settings: two hospitals, two rehabilitation clinics and three cardiology practices in Cologne, Germany. Patients were screened for angiographically documented CHD and other inclusion criteria. In total, 364 CHD patients took part in this study. It consisted of two parts: In the first part, participants filled in a newly developed questionnaire about their psychological needs, access and barriers within the healthcare system and their contact with their doctor in these matters. Then, patients were screened for MHIs with the help of the Hospital Anxiety and Depression Scale (HADS). When a score above seven was scored on the HADS, patients were additionally screened for specific MHIs using the Structured Clinical Interview for DSM-IV Axis I Disorders. In the second part, 20 participants were subsequently interviewed in a semi-structured interview to generate more in-depth findings. RESULTS: The interviews show that CHD patients with and without MHI experienced a cardiac event as life-changing and had an urgent need to talk about CHD with their doctor, mostly the general practitioner (GP). When the GP spoke to the patient shortly after the cardiac event, patients experienced relief and were better able to cope with their illness. Only 9.1% reported being aided in their search for psychotherapeutic treatment or drug treatment (4.1%). CONCLUSION: The needs of CHD patients with and without MHI were not adequately satisfied within our sample. Psychological measures are necessary for sufficient improvement, such as training of doctors in doctor-patient communication (e.g., better support in coping with MHI/CHD), improvements in the procedure (more time for conversations during doctor contacts), and improvement of structural requirements (referring patients faster to psychotherapists). PATIENT OR PUBLIC CONTRIBUTION: We received input from patients during pretests and used the feedback to tailor our questionnaire and the interview guidelines. Afterwards, we disseminated the main results for the patient and public involvement (e.g., public lectures, leaflets for self-help groups, etc.).

Family functioning and health-related quality of life of inpatients with coronary heart disease: a cross-sectional study in Lanzhou city, China.

BACKGROUND: A key outcome in coronary heart disease (CHD) is Health Related Quality of Life (HRQoL), and family functioning is important in the management of CHD. But few studies have examined both together, and little is known about them among inpatients with CHD in less developed areas of China. Therefore, this study aimed to assess the HRQoL and family functioning status of inpatients with CHD in Lanzhou from Northwest China, and identify the factors that affect their HRQoL. METHODS: A cross­sectional study was conducted in 224 CHD inpatients at one major hospital. Sociodemographic data and disease information of CHD inpatients were collected by face-to-face using a structured questionnaire and data were also obtained from patient medical records. HRQoL was measured using the Sickness Impact Profile (SIP). Family functioning was measured using the family APGAR index. Multiple binary logistic regression analysis (MBLRA) was used to explore potential risk factors associated with HRQoL, and Pearson's correlations were used to assess the relationship between family functioning and HRQoL. RESULTS: The overall, physical and psychosocial SIP scores were 25.03 ± 8.52, 18.61 ± 9.90 and 28.08 ± 9.64, respectively. The total family APGAR score was 6.11 ± 2.45. MBLRA found older age, poorer cardiac function and more severe disease were associated with poorer HRQoL, while better family functioning, higher monthly income, and urban living were associated with better HRQoL. Family functioning was weakly to moderately correlated with total and psychosocial HRQoL. CONCLUSIONS: Older and less affluent inpatients with lower educational level, less family support and more severe CHD have poorest quality of life, and health care providers should consider interventions to support them.

Intimate Relationships and Coronary Heart Disease: Implications for Risk, Prevention, and Patient Management.

PURPOSE OF REVIEW: Research and clinical services addressing psychosocial aspects of coronary heart disease (CHD) typically emphasize individuals, focusing less on the context of intimate relationships such as marriage and similar partnerships. This review describes current evidence regarding the role of intimate relationships in the development, course, and management of CHD. RECENT FINDINGS: Having an intimate partner is associated with reduced risk of incident CHD and a better prognosis among patients, but strain (e.g., conflict) and disruption (i.e., separation, divorce) in these relationships are associated with increased risk and poor outcomes. These associations likely reflect mechanisms involving health behavior and the physiological effects of emotion and stress. Importantly, many other well-established psychosocial risk and protective factors (e.g., low SES, job stress, depression, and optimism) are strongly related to the quality of intimate relationships, and these associations likely contribute to the effects of those other psychosocial factors. For better or worse, intimate partners can also affect the outcome of efforts to alter health behaviors (physical activity, diet, smoking, and medication adherence) central in the prevention and management CHD. Intimate partners also influence-and are influenced by-stressful aspects of acute coronary crises and longer-term patient adjustment and management. Evidence on each of these roles of intimate relationships in CHD is considerable, but direct demonstrations of the value of couple assessments and interventions are limited, although preliminary research is promising. Research needed to close this gap must also address issues of diversity, disparities, and inequity that have strong parallels in CHD and intimate relationships.

A systematic review, meta-analysis, and meta-regression of patient education for secondary prevention in patients with coronary heart disease: impact on psychological outcomes.

BACKGROUND: Patient education is a cardiac rehabilitation core component and is associated with improvements in self-management of patients with coronary heart disease (CHD). However, the efficacy of such interventions on psychosocial outcomes and relative impact of duration is less clear. OBJECTIVES: This study aimed to assess the efficacy of patient education for secondary prevention related to behaviour change and risk factor modification on psychological outcomes in CHD patients. DESIGN: A systematic review and meta-analysis. DATA SOURCES: PsycINFO, CINAHL, Embase, EmCare, MEDLINE, PubMed, and the Cochrane Central Register of Controlled Trials were searched from inception to February 2021. ELIGIBILITY CRITERIA FOR STUDY SELECTION: Randomized controlled trials (RCTs) evaluating patient education in CHD patients, or following myocardial infarction, or revascularization compared with usual care were identified. Outcomes included depression and anxiety at <6 and 6-12 months of follow-up. RESULTS: A total of 39 RCTs and 8748 participants were included. Patient education significantly improved participants' depressive symptoms at <6 (SMD -0.82) and 6-12 months (SMD -0.38) of follow-up and anxiety level at <6 (SMD -0.90), and 6-12 months (SMD -0.32) of follow-up. Patient education also reduced the risk for having clinical depression by 35% and anxiety by 60%. Longer patient education of ≥3 months, resulted in more improvement in depressive symptoms at 6-12 months (coefficient -0.210) compared to shorter duration. CONCLUSIONS: Patient education for secondary prevention reduces anxiety and depressive symptoms in CHD patients. Regardless of intensity, longer patient education improves depression more than short duration. More information is needed on the relative impact of other intervention components.
