Mental disorders across the adult life course and future coronary heart disease: evidence for general susceptibility

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

BACKGROUND

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

OBJECTIVES

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

SEARCH METHODS

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

SELECTION CRITERIA

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

DATA COLLECTION AND ANALYSIS

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

MAIN RESULTS

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

AUTHORS' CONCLUSIONS

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

Projecting genetic associations through gene expression patterns highlights disease etiology and drug mechanisms

Genes act in concert with each other in specific contexts to perform their functions. Determining how these genes influence complex traits requires a mechanistic understanding of expression regulation across different conditions. It has been shown that this insight is critical for developing new therapies. Transcriptome-wide association studies have helped uncover the role of individual genes in disease-relevant mechanisms. However, modern models of the architecture of complex traits predict that gene-gene interactions play a crucial role in disease origin and progression. Here we introduce PhenoPLIER, a computational approach that maps gene-trait associations and pharmacological perturbation data into a common latent representation for a joint analysis. This representation is based on modules of genes with similar expression patterns across the same conditions. We observe that diseases are significantly associated with gene modules expressed in relevant cell types, and our approach is accurate in predicting known drug-disease pairs and inferring mechanisms of action. Furthermore, using a CRISPR screen to analyze lipid regulation, we find that functionally important players lack associations but are prioritized in trait-associated modules by PhenoPLIER. By incorporating groups of co-expressed genes, PhenoPLIER can contextualize genetic associations and reveal potential targets missed by single-gene strategies.

Increased risk of incident atrial fibrillation in young adults with mental disorders: A nationwide population-based study

BACKGROUND

Mental disorders and cardiovascular diseases are closely related. However, a paucity of information on the risk of incident atrial fibrillation (AF) in patients with mental disorders exists.

OBJECTIVE

We aimed to assess the association between mental disorders and the risk of AF, particularly in young adults.

METHODS

Using the Korean National Health Insurance Database between 2009 and 2012, we identified adults aged 20-39 years without a history of AF and who have been diagnosed with mental disorders. Mental disorders were defined as having one of the following diagnoses: depression, insomnia, anxiety disorder, bipolar disorder, or schizophrenia. The primary outcome was new-onset AF during follow-up.

RESULTS

A total of 6,576,582 subjects (mean age 30.9 ± 5.0 years; 3,919,339 [59.6%] men) were included. Among the total population, 10% had mental disorders. During the follow-up period, 8932 incident AF events occurred. Patients with mental disorders showed a higher AF incidence than did those without (25.4 per 100,000 person-years vs 17.7 per 100,000 person-years). After multivariable adjustment, mental disorders were associated with a significantly higher risk of AF (adjusted hazard ratio 1.526; 95% confidence interval 1.436-1.621). Patients with bipolar disorder or schizophrenia had a 2-fold higher risk of AF and those with depression, insomnia, and anxiety disorder had a 1.5- to 1.7-fold higher risk of AF than did those without mental disorders.

CONCLUSION

Young adults diagnosed with mental disorders have a higher risk of incident AF. Awareness for AF in high-risk populations should thus be considered.

Validity of a German Comprehensive Psychosocial Screening Instrument based on the ESC Cardiovascular Prevention Guidelines

Background: Following guidelines for cardiovascular disease prevention of the European Society for Cardiology (ESC), the current study validated the German Comprehensive Psychosocial Screening Instrument in participants who underwent coronary angiography. Methods: 314 participants (M_age = 69.7 ± 12.0; 69 % male) completed the German Comprehensive Psychosocial Screening Instrument and validated comparison scales to measure depression (PHQ-9), anxiety (GAD-7), Type D personality (DS14), work stress (ERI), family stress (SMSS), trauma (PC-PTSD), and anger and hostility (Z-scale of MMPI-2). Results: Confirmatory factor analysis (CFA) confirmed that the psychosocial risk factors were separate entities rather than a signs or symptoms of a single broad indication of distress (CFI = .872, RMSEA = .056, SRMR = .058). Intraclass coefficients (ICC), kappa and diagnostic accuracy indicators (receiver operator characteristic [ROC] curves, sensitivity, specificity, and the positive and negative predictive values [PPV; NPV]) indicated that most screener scales were sufficient to good. We also compared patients with established coronary heart disease (CHD; n = 213) to those with no current CHD (n = 100) and found overall similar results. Discussion: The German version of the Comprehensive Psychosocial Screening Instrument has an acceptable performance. Aside from minor improvements, the screening instrument could be implemented in the cardiological practice to screen patients on multidimensional psychosocial risk.

The efficacy of exercise interventions for all types of inpatients across mental health settings: A systematic review and meta-analysis of 47 studies

This systematic review and meta-analysis investigated the benefits, safety and adherence of exercise interventions delivered in inpatient mental health settings, quantified the number of exercise trials that provided support to maintain engagement in exercise post-discharge, and reported patient feedback towards exercise interventions. Major databases were searched from inception to 22.06.2022 for intervention studies investigating exercise in mental health inpatient settings. Study quality was assessed using Cochrane and ROBINS-1 checklists. Fifty-six papers were included from 47 trials (including 34 RCTs), bias was high. Exercise improved depression (Standardised mean difference = -0.416; 95% Confidence interval -0.787 to -0.045, N = 15) compared to non-exercise comparators amongst people with a range of mental illnesses, with further (albeit limited) evidence suggesting a role of exercise in cardiorespiratory fitness and various other physical health parameters and ameliorating psychiatric symptoms. No serious exercise-related adverse events were noted, attendance was ≥80% in most trials, and exercise was perceived as enjoyable and useful. Five trials offered patients post-discharge support to continue exercise, with varying success. In conclusion, exercise interventions may have therapeutic benefits in inpatient mental health settings. More high-quality trials are needed to determine optimal parameters, and future research should investigate systems to support patients to maintain exercise engagement once discharged.

Prevalence and risk factors of cardiovascular diseases and psychological distress among female scientists and technicians

This study aimed to explore the prevalence and risk factors of cardiovascular disease (CVD) and psychological distress among female scientists and technicians in China. Accordingly, we included scientists and technicians from representative research institutions, medical institutions, colleges, universities, and businesses in China, and the data were collected from July 1, 2019 to March 31, 2021 via online questionnaires. The parameters evaluated in this study included age, sex, marital status, educational background, monthly income, sleep hours, sleep problems, smoking, alcohol consumption, work-related stress, work burnout, cardiovascular symptoms, CVD, family history, and depressive and anxiety symptoms. A total of 14 530 scientists and technicians were included, comprising 7144 men and 7386 women. We found 34.9% men and 16.6% women with CVD, 35.1% men and 21.4% women with depressive symptoms, 28.7% men and 13.8% women with anxiety symptoms, and 22.0% men and 9.5% women with CVD combined with depressive or anxiety symptoms. This study focused on the details of women. Younger women (age≤35 years) had the highest prevalence of depressive symptoms (24.9%), anxiety symptoms (16.2%), and comorbidity (11.2%). It was established that, despite traditional risk factors, unmanageable work burnout, depressive symptoms, and anxiety symptoms were associated with a higher risk of CVD in women; insomnia, overwhelming work stress, unmanageable work burnout, and CVD were linked to a higher risk of depressive symptoms and anxiety; insomnia, overwhelming work stress, and unmanageable work burnout were related to CVD combined with depressive or anxiety symptoms. A bidirectional relationship was noted between CVD and depression or anxiety in female scientists and technicians, and insomnia and overwhelming work stress were positively associated with comorbidity. It is suggested that effective measures should be taken to protect female scientists and technicians from CVD and psychological distress.

Effect of Patient-Reported Preprocedural Physical and Mental Health on 10-Year Mortality After Percutaneous or Surgical Coronary Revascularization

BACKGROUND

Clinical and anatomical characteristics are often considered key factors in deciding between percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) in patients with complex coronary artery disease (CAD) such as left-main CAD or 3-vessel disease. However, little is known about the interaction between self-reported preprocedural physical/mental health and clinical outcomes after revascularization.

METHODS

This subgroup analysis of the SYNTAXES trial (SYNTAX Extended Survival), which is the extended follow-up of the randomized SYNTAX trial (Synergy Between PCI With Taxus and Cardiac Surgery) comparing PCI with CABG in patients with left-main CAD or 3-vessel disease, stratified patients by terciles of Physical (PCS) or Mental Component Summary (MCS) scores derived from the preprocedural 36-Item Short Form Health Survey, with higher PCS and MCS scores representing better physical and mental health, respectively. The primary end point was all-cause death at 10 years.

RESULTS

A total of 1656 patients with preprocedural 36-Item Short Form Health Survey data were included in the present study. Both higher PCS and MCS were independently associated with lower 10-year mortality (10-point increase in PCS adjusted hazard ratio, 0.84 [95% CI, 0.73-0.97]; P=0.021; in MCS adjusted hazard ratio, 0.85 [95% CI, 0.76-0.95]; P=0.005). A significant survival benefit with CABG over PCI was observed in the highest PCS (>45.5) and MCS (>52.3) terciles with significant treatment-by-subgroup interactions (PCS P_interaction=0.033, MCS P_interaction=0.015). In patients with both high PCS (>45.5) and MCS (>52.3), 10-year mortality was significantly higher with PCI compared with CABG (30.5% versus 12.2%; hazard ratio, 2.87 [95% CI, 1.55-5.30]; P=0.001), whereas among those with low PCS (≤45.5) or low MCS (≤52.3), there were no significant differences in 10-year mortality between PCI and CABG, resulting in a significant treatment-by-subgroup interaction (P_interaction=0.002).

CONCLUSIONS

Among patients with left-main CAD or 3-vessel disease, patient-reported preprocedural physical and mental health status was strongly associated with long-term mortality and modified the relative treatment effects of PCI versus CABG. Patients with the best physical and mental health had better 10-year survival with CABG compared with PCI. Assessment of self-reported physical and mental health is important when selecting the optimal revascularization strategy.

This study uses a bibliometric approach to visualize and analyze the literature within the field of psycho-cardiology over the last 20 years to visualize the development process, research hotspots, and cutting-edge trends in clinical practice, mechanisms, and management strategies related to psycho-cardiology. Quantitative description and evaluation of 409 articles published in the field from 2004-2022 were conducted using CiteSpace and VOSviewer, to provide a theoretical reference for the development of psycho-cardiology.

Validity of a multidimensional comprehensive psychosocial screening instrument based on the ESC cardiovascular prevention guidelines - Evidence from the general and cardiovascular patient population

AIM

To evaluate the psychometric properties and validity of the updated version of the Dutch multidimensional Comprehensive Psychosocial Screening Instrument in patients with coronary heart disease and the general population, based upon guideline recommendations from the European Society for Cardiology.

METHOD

678 participants (M_age = 48.2, SD = 16.8; 46% male) of the Dutch general population and 312 cardiac patients (M_age = 65.9, SD = 9.9; 77% male) who recently received percutaneous coronary intervention completed the Comprehensive Psychosocial Screening Instrument and validated questionnaires for depression (PHQ-9), anxiety (GAD-7), Type D personality (DS14), hostility (CMHS), anger (STAS-T), trauma (SRIP), and chronic work and family stress (ERI, MMQ-6).

RESULTS

Confirmatory factor analysis (CFA) confirmed that the eight screened risk factors were best measured as separate entities, rather than broader indications of distress. Inter-instrument agreement, assessed with the intraclass coefficient (ICC) and the screening accuracy indicators (receiving operator characteristic [ROC] curves, sensitivity, specificity, and the positive and negative predictive values [PPV; NPV]) were good for most screened risk factors. PPV was low in low prevalence risk factors like anxiety, trauma, and depression.

CONCLUSION

Overall, the current version of the Comprehensive Psychosocial Screening Instrument has an acceptable performance in both populations, with a fair to excellent level of agreement with established full questionnaires. Besides a few suggestions for further refinement, the screener may be implemented in primary care and cardiological practice.

Modifiable risk factors in adults with and without prior cardiovascular disease: findings from the Indonesian National Basic Health Research

Backgrounds

The majority of risk factors for cardiovascular diseases (CVDs) are modifiable. Continuous monitoring and control of these factors could significantly reduce the risk of CVDs-related morbidity and mortality. This study estimated the prevalence of modifiable risk factors in Indonesia and its co-occurence of multiple risk factors stratified by prior CVDs diagnosis status and sex.

Methods

Adult participants (> 15 years, N = 36,329, 57% women) with median age of 40 years were selected from a nationwide Indonesian cross-sectional study called Basic Health Research or Riset Kesehatan Dasar (Riskesdas) conducted in 2018. Thirteen risk factors were identified from the study, including smoking, a high-risk diet, inadequate fruit and vegetable consumption, a low physical activity level, the presence of mental-emotional disorders, obesity, a high waist circumference (WC), a high waist-to-height ratio (WtHR), hypertension, diabetes, a high total cholesterol level, a high low-density lipoprotein (LDL) cholesterol level, and a low high-density lipoprotein (HDL) cholesterol level. Age-adjusted prevalence ratios stratified by CVDs status and sex were calculated using Poisson regression with the robust covariance estimator.

Results

CVDs were found in 3% of the study population. Risk factor prevalence in the overall population ranged from 5.7 to 96.5% for diabetes and inadequate fruit and vegetable consumption respectively. Smoking, a high-risk food diet, and a low HDL cholesterol level were more prevalent in men, whereas a low physical activity level, the presence of mental-emotional disorders, obesity, a high WC, a high WtHR, hypertension, diabetes, a high total cholesterol level, and a high LDL cholesterol level were more prevalent in women. Approximately 22% of men and 18% of women had at least 4 risk factors, and these proportions were higher in participants with prior CVDs diagnosis.

Conclusions

There is a high prevalence of modifiable risk factors in the Indonesian adult population. Sex, age, and the presence of CVD are major determinants of the variations in risk factors. The presence of multiple risk factors, which are often inter-related, requires a comprehensive approach through health promotion, lifestyle modification and patient education.

Temporal trends in associations between severe mental illness and risk of cardiovascular disease: A systematic review and meta-analysis

BACKGROUND

Severe mental illness (SMI; schizophrenia, bipolar disorders (BDs), and other nonorganic psychoses) is associated with increased risk of cardiovascular disease (CVD) and CVD-related mortality. To date, no systematic review has investigated changes in population level CVD-related mortality over calendar time. It is unclear if this relationship has changed over time in higher-income countries with changing treatments.

METHODS AND FINDINGS

To address this gap, a systematic review was conducted, to assess the association between SMI and CVD including temporal change. Seven databases were searched (last: November 30, 2021) for cohort or case-control studies lasting ≥1 year, comparing frequency of CVD mortality or incidence in high-income countries between people with versus without SMI. No language restrictions were applied. Random effects meta-analyses were conducted to compute pooled hazard ratios (HRs) and rate ratios, pooled standardised mortality ratios (SMRs), pooled odds ratios (ORs), and pooled risk ratios (RRs) of CVD in those with versus without SMI. Temporal trends were explored by decade. Subgroup analyses by age, sex, setting, world region, and study quality (Newcastle-Ottawa scale (NOS) score) were conducted. The narrative synthesis included 108 studies, and the quantitative synthesis 59 mortality studies (with (≥1,841,356 cases and 29,321,409 controls) and 28 incidence studies (≥401,909 cases and 14,372,146 controls). The risk of CVD-related mortality for people with SMI was higher than controls across most comparisons, except for total CVD-related mortality for BD and cerebrovascular accident (CVA) for mixed SMI. Estimated risks were larger for schizophrenia than BD. Pooled results ranged from SMR = 1.55 (95% confidence interval (CI): 1.33 to 1.81, p < 0.001), for CVA in people with BD to HR/rate ratio = 2.40 (95% CI: 2.25 to 2.55, p < 0.001) for CVA in schizophrenia. For schizophrenia and BD, SMRs and pooled HRs/rate ratios for CHD and CVD mortality were larger in studies with outcomes occurring during the 1990s and 2000s than earlier decades (1980s: SMR = 1.14, 95% CI: 0.57 to 2.30, p = 0.71; 2000s: SMR = 2.59, 95% CI: 1.93 to 3.47, p < 0.001 for schizophrenia and CHD) and in studies including people with younger age. The incidence of CVA, CVD events, and heart failure in SMI was higher than controls. Estimated risks for schizophrenia ranged from HR/rate ratio 1.25 (95% CI: 1.04 to 1.51, p = 0.016) for total CVD events to rate ratio 3.82 (95% CI: 3.1 to 4.71, p < 0.001) for heart failure. Incidence of CHD was higher in BD versus controls. However, for schizophrenia, CHD was elevated in higher-quality studies only. The HR/rate ratios for CVA and CHD were larger in studies with outcomes occurring after the 1990s. Study limitations include the high risk of bias of some studies as they drew a comparison cohort from general population rates and the fact that it was difficult to exclude studies that had overlapping populations, although attempts were made to minimise this.

CONCLUSIONS

In this study, we found that SMI was associated with an approximate doubling in the rate ratio of CVD-related mortality, particularly since the 1990s, and in younger groups. SMI was also associated with increased incidence of CVA and CHD relative to control participants since the 1990s. More research is needed to clarify the association between SMI and CHD and ways to mitigate this risk.

Herzerkrankungen im Langzeitverlauf: Wie kann die psychosoziale Versorgung verbessert werden?

Herz-Kreislauf-Erkrankungen, zu denen in erster Linie die koronare Herzerkrankung (KHK), Herzrhythmusstörungen und die Herzinsuffizienz (HI) gehören, sind für die meisten Todesfälle und schwerwiegenden Krankheitsverläufe in der Europäischen Union verantwortlich. Das akute Geschehen steht meist im Vordergrund der klinischen Aufmerksamkeit. Dagegen existieren für den Langzeitverlauf dieser Krankheitsbilder kaum strukturierte Versorgungs- und Therapiekonzepte. Der vorliegende Beitrag gibt auf Grundlage einer Literaturrecherche eine Übersicht über die Langzeitfolgen und die Langzeitversorgung von Herzerkrankungen. Defizite in der psychosozialen Versorgung der Patienten und mögliche Lösungsansätze werden diskutiert.

Bei Patienten mit KHK ergeben sich aufgrund einer mangelhaften psychosozialen Langzeitversorgung häufig Probleme mit der Medikamententreue und der Einhaltung von Verhaltensempfehlungen. Psychische Komorbiditäten reduzieren die Lebensqualität und sind ein Antreiber für gesundheitsschädigendes Verhalten. Patienten mit Herzrhythmusstörungen geraten häufig in einen Teufelskreis aus wiederkehrenden körperlichen Beschwerden in Wechselwirkung mit Angst- und Panikattacken und der damit verbundenen Inanspruchnahme ambulanter, notärztlicher oder stationärer Versorgungseinrichtungen. Im Krankheitsverlauf einer Herzinsuffizienz wird eine klinisch bedeutsam wachsende Anzahl von Patienten mit Antidepressiva behandelt, deren Nutzen eher zweifelhaft ist.

Die erkennbaren Defizite der psychosozialen Langzeitversorgung von Herzerkrankungen können durch die verstärkte Anwendung systematischer kollaborativer Versorgungsmodelle von spezialisierten Versorgungseinrichtungen unter Einbeziehung von Hausärzten behoben und die Lebensqualität der Patienten verbessert werden.

Psychological Disturbances and Their Association with Sleep Disturbance in Patients Admitted for Arrhythmia Diseases

OBJECTIVES

This study aimed to assess the depression and anxiety status and their association with sleep disturbance among one single center Chinese inpatients with arrhythmia and help cardiologists better identify patients who need psychological care.

METHODS

A cross-sectional survey was conducted among 495 inpatients with arrhythmia treated in Fuwai Hospital from October to December 2019. The psychological status and sleep quality were assessed using the Zung Self-Rating Anxiety Scale (SAS), the Zung Self-Rating Depression Scale (SDS) and the Pittsburgh Sleep Quality Index (PSQI). Multivariate logistic regression was used to identify the potential risk factors for anxiety and depression.

RESULTS

The mean age of the participants was 52.8 ± 14.4 years, and 58.0% were male. Approximately 18.3% were in an anxious state, and 33.5% were in a depressive state. In multivariate logistic regression, age from 50 to 59 (p = 0.03), unemployment (p = 0.026) and sleep disturbance (p < 0.001) were the risk factors for anxiety status. Cardiac implanted electronic devices (CIEDs) (p = 0.004) and sleep disturbance (p < 0.001) were the risk factors for depression status. A total of 150 patients (30.3%) were categorized as having poor sleep quality (PSQI > 7). The adjusted odds ratio (OR) of having poor sleep quality was 4.30-fold higher in patients with both anxiety and depression (OR: 4.30; 95% confidence interval [CI]: 2.52-7.35); 2.67-fold higher in patients with depression (OR: 2.67; 95% CI: 1.78-4.00); and 3.94-fold higher in patients with anxiety (OR: 3.94; 95% CI: 2.41-6.44).

CONCLUSIONS

Psychological intervention is critical for Chinese inpatients with arrhythmia, especially for patients aged 50-59, unemployed, or those using CIEDs. Poor sleep quality could be an important risk factor linked to psychological disturbances.

Validity and Reliability of the Urdu Version of the McLean Screening Instrument for Borderline Personality Disorder

Introduction: Although the translation and the validation of the McLean Screening Instrument for Borderline Personality Disorder (MSI-BPD) are performed in various languages and samples, no study has established the validity and reliability of the Urdu version of MSI-BPD in individuals with cardiac problems. Materials and Methods: The Urdu version of the MSI-BPD was prepared through the standard back-translation method. The translation and adaption were completed in four steps: forward translation, adaption and translation, back translation and committee approach, and cross-language validation. The sample, selected through the purposive sampling method, comprised of 150 adults with cardiac problems (men = 75 and women = 75), with an age range of 23-78 years (M = 55, SD = 10.6). The Cronbach alpha reliability and factorial validity of the MSI-BPD were assessed through confirmatory factor analysis (CFA) and Pearson correlation analyses. Internal consistency and test-retest reliability (at 2 weeks' interval) were used to evaluate the reliability. Statistical analyses were performed, using SPSS (version 22) and Structural Equation Modeling (SEM) software. Results: Preliminary analysis revealed that the overall instrument had good internal consistency (Urdu MSI-BPD α = 0.79; English MSI-BPD α = 0.77) as well as test-retest correlation coefficients for 15 days (r = 0.94). Conclusions: Findings suggested that the MSI-BPD, with important limitations, can be used as an effective preliminary screening tool to measure BPD in Urdu-speaking adults with cardiac problems. Further validations should be conducted to make the translated version of the MSI-BPD an appropriate tool to screen BPD in hospitals and mental health care settings.

Greater Arterial Stiffness in Children with or without Second-generation Antipsychotic Treatment for Mental Health Disorders: Rigidité Artérielle Plus Importante Chez Les Enfants Avec ou Sans Traitement Par Antipsychotiques de la Deuxième Génération Pour des Troubles de Santé Mentale

OBJECTIVE

Second-generation antipsychotics (SGAs) are used for a variety of mental disorders and are associated with cardiometabolic side effects in children. The objective of this study was to assess the cardiovascular health of children with mental disorders that are SGA-treated or SGA-naive.

METHODS

SGA-treated (n = 47) or SGA-naive (n = 37) children (aged 6 to 18 years) with mental disorders and control children (n = 83, no mental disorder) underwent assessment for cardiac function and morphology by echocardiography, aortic pulse wave velocity (PWV), and carotid intima-media thickness (cIMT). Body mass index (BMI) z-scores, waist circumference z-scores, systolic and diastolic blood pressure (BP) percentiles for height and sex, and fasting plasma glucose, insulin, triglycerides, and cholesterol were also assessed. Differences between SGA-treated, SGA-naive, and control children were assessed by linear and log-linear regression models.

RESULTS

SGA-treated children had greater BMI z-scores and overweight/obesity (BMI ≥ 85th percentile for age and sex) and hypertension than SGA-naive and control children. The PWV geometric mean was 11.1% higher in SGA-treated (95%CI, 3.95 to 18.77) and 12.9% higher in SGA-naive children (95% CI, 5.60 to 20.59) compared to controls in models adjusted for age, sex, BMI, and systolic BP percentile. Left ventricular (LV) end-diastolic dimension/body surface area (BSA), LV end-systolic dimension/BSA, and LV ejection fraction were lower in SGA-treated and SGA-naive children compared to controls in models adjusted for sex and age.

CONCLUSIONS

Children with mental disorders have greater arterial stiffness and altered cardiac structure/function than children with no mental health diagnosis. SGA treatment in children is not associated with alterations in cardiovascular structure/function.

The lipid paradox in neuroprogressive disorders: Causes and consequences

Chronic systemic inflammation is associated with an increased risk of cardiovascular disease in an environment of low low-density lipoprotein (LDL) and low total cholesterol and with the pathophysiology of neuroprogressive disorders. The causes and consequences of this lipid paradox are explored. Circulating activated neutrophils can release inflammatory molecules such as myeloperoxidase and the pro-inflammatory cytokines interleukin-1 beta, interleukin-6 and tumour necrosis factor-alpha. Since activated neutrophils are associated with atherosclerosis and cardiovascular disease and with major depressive disorder, bipolar disorder and schizophrenia, it seems reasonable to hypothesise that the inflammatory molecules released by them may act as mediators of the link between systemic inflammation and the development of atherosclerosis in neuroprogressive disorders. This hypothesis is tested by considering the association at a molecular level of systemic inflammation with increased LDL oxidation; increased small dense LDL levels; increased lipoprotein (a) concentration; secretory phospholipase A₂ activation; cytosolic phospholipase A₂ activation; increased platelet activation; decreased apolipoprotein A1 levels and function; decreased paroxonase-1 activity; hyperhomocysteinaemia; and metabolic endotoxaemia. These molecular mechanisms suggest potential therapeutic targets.

The role of high-density lipoprotein cholesterol, apolipoprotein A and paraoxonase-1 in the pathophysiology of neuroprogressive disorders

Lowered high-density lipoprotein (HDL) cholesterol has been reported in major depressive disorder, bipolar disorder, first episode of psychosis, and schizophrenia. HDL, its major apolipoprotein component, ApoA1, and the antioxidant enzyme paraoxonase (PON)1 (which is normally bound to ApoA1) all have anti-atherogenic, antioxidant, anti-inflammatory, and immunomodulatory roles, which are discussed in this paper. The paper details the pathways mediating the anti-inflammatory effects of HDL, ApoA1 and PON1 and describes the mechanisms leading to compromised HDL and PON1 levels and function in an environment of chronic inflammation. The molecular mechanisms by which changes in HDL, ApoA1 and PON1 might contribute to the pathophysiology of the neuroprogressive disorders are explained. Moreover, the anti-inflammatory actions of ApoM-mediated sphingosine 1-phosphate (S1P) signalling are reviewed as well as the deleterious effects of chronic inflammation and oxidative stress on ApoM/S1P signalling. Finally, therapeutic interventions specifically aimed at improving the levels and function of HDL and PON1 while reducing levels of inflammation and oxidative stress are considered. These include the so-called Mediterranean diet, extra virgin olive oil, polyphenols, flavonoids, isoflavones, pomegranate juice, melatonin and the Mediterranean diet combined with the ketogenic diet.

Severity, Progress, and Related Factors of Mood Disorders in Patients with Coronary Artery Disease: A Retrospective Study

Patients with coronary artery disease (CAD) are more likely to experience depression and anxiety, which, in turn, are risk factors for CAD. The Beck depression inventory (BDI) and Beck anxiety inventory (BAI) were applied for mood evaluation during hospitalization and again 3 months after discharge in 118 patients with CAD, and cardiopulmonary exercise tests were conducted in the outpatient department. Of the patients diagnosed with CAD, 40 (33.9%) had depressive moods, and 51 (43.2%) had anxious moods. A family history of CAD, low Korean activity scale index (KASI), and use of beta-blockers were independent factors causing depressive mood, while lower left ventricular ejection fraction (LVEF) and low KASI score were independent factors causing anxious mood. A considerable number of patients (35.7% with depressive mood and 25.0% with anxious mood) still had emotional problems after 3 months of discharge. The change values of BDI were associated with lower LVEF and longer hospital stay, while those of BAI was associated with a longer hospital stay. Since some patients had depressive and anxious moods after three months of discharge, evaluating and treating them are essential.

Increased ABCA1 (ATP-Binding Cassette Transporter A1)-Specific Cholesterol Efflux Capacity in Schizophrenia

Objective:

Patients with schizophrenia have increased long-term mortality attributable to cardiovascular disease and commonly demonstrate features of mixed dyslipidemia with low HDL-C (high-density lipoprotein cholesterol). The removal of cholesterol from cells by HDL via specific ATP-binding cholesterol transporters is a major functional property of HDL, and its measurement as cholesterol efflux capacity (CEC) can predict cardiovascular risk. Whether HDL function is impaired in patients with schizophrenia is unknown.

Approach and Results:

We measured basal and ABCA1 (ATP-binding cassette transporter A1)- and ABCG1 (ATP-binding cassette transporter G1)-dependent CEC, comparing patients with schizophrenia with age- and sex-matched healthy controls, and related our findings to nuclear magnetic resonance analysis of lipoprotein subclasses. Total plasma cholesterol and LDL-C (low-density lipoprotein cholesterol) were comparable between healthy controls (n=51) and patients (n=120), but patients with schizophrenia had increased total plasma triglyceride, low HDL-C and apo (apolipoprotein) A-I concentrations. Nuclear magnetic resonance analysis indicated a marked (15-fold) increase in large triglyceride-rich lipoprotein particle concentration, increased small dense LDL particles, and fewer large HDL particles. Despite lower HDL-C concentration, basal CEC was 13.7±1.6% higher, ABCA1-specific efflux was 35.9±1.6% higher, and ABCG1 efflux not different, in patients versus controls. In patients with schizophrenia, ABCA1-specific efflux correlated with the abundance of small 7.8 nm HDL particles but not with serum plasminogen or triglyceride levels.

Conclusions:

Patients with schizophrenia have increased concentrations of atherogenic apoB-containing lipoproteins, decreased concentrations of large HDL particles, but enhanced ABCA1-mediated CEC. In this population, preventative strategies should focus on reducing atherogenic lipoproteins rather than increasing CEC.

Endothelial dysfunction in neuroprogressive disorders-causes and suggested treatments

BACKGROUND

Potential routes whereby systemic inflammation, oxidative stress and mitochondrial dysfunction may drive the development of endothelial dysfunction and atherosclerosis, even in an environment of low cholesterol, are examined.

MAIN TEXT

Key molecular players involved in the regulation of endothelial cell function are described, including PECAM-1, VE-cadherin, VEGFRs, SFK, Rho GEF TRIO, RAC-1, ITAM, SHP-2, MAPK/ERK, STAT-3, NF-κB, PI3K/AKT, eNOS, nitric oxide, miRNAs, KLF-4 and KLF-2. The key roles of platelet activation, xanthene oxidase and myeloperoxidase in the genesis of endothelial cell dysfunction and activation are detailed. The following roles of circulating reactive oxygen species (ROS), reactive nitrogen species and pro-inflammatory cytokines in the development of endothelial cell dysfunction are then described: paracrine signalling by circulating hydrogen peroxide, inhibition of eNOS and increased levels of mitochondrial ROS, including compromised mitochondrial dynamics, loss of calcium ion homeostasis and inactivation of SIRT-1-mediated signalling pathways. Next, loss of cellular redox homeostasis is considered, including further aspects of the roles of hydrogen peroxide signalling, the pathological consequences of elevated NF-κB, compromised S-nitrosylation and the development of hypernitrosylation and increased transcription of atherogenic miRNAs. These molecular aspects are then applied to neuroprogressive disorders by considering the following potential generators of endothelial dysfunction and activation in major depressive disorder, bipolar disorder and schizophrenia: NF-κB; platelet activation; atherogenic miRs; myeloperoxidase; xanthene oxidase and uric acid; and inflammation, oxidative stress, nitrosative stress and mitochondrial dysfunction.

CONCLUSIONS

Finally, on the basis of the above molecular mechanisms, details are given of potential treatment options for mitigating endothelial cell dysfunction and activation in neuroprogressive disorders.

Sex- and Gender-Stratified Risks of Psychological Factors for Incident Ischemic Heart Disease: Systematic Review and Meta-Analysis

Background

Psychological factors are associated with an increased risk of developing ischemic heart disease (IHD). Women more often report psychological factors, and sex and gender differences are present in IHD. In this meta‐analysis we examine the risks of psychological factors for IHD incidence in women and men. We hypothesize that a broad range of psychological factors are related to a higher risk for incident IHD, with a higher risk for women.

Methods and Results

PubMed, EMBASE, and PsycINFO were searched for studies assessing the risk between psychological factors and incident IHD. Psychological factors included depression, anxiety or panic disorder, social support, hostility, anger, personality (type D), type A behavior pattern, posttraumatic stress disorder, and psychological distress. In the primary analyses, 62 studies (77 separate reports) that included 2 145 679 women and 3 119 879 men and reported confounder‐adjusted hazard ratios or relative risks were included. Pooled effect confounder‐adjusted estimates from random‐effects models showed that psychological factors (all combined) were associated with incident IHD in women (hazard ratio: 1.22; 95% CI, 1.14–1.30) and men (hazard ratio: 1.25; 95% CI, 1.19–1.31). No sex and gender differences were found for these pooled effect estimates (P=0.547).

Conclusions

Psychological factors are associated with incident IHD in both women and men, but no significant differences were observed between women and men. IHD is predominantly being studied as obstructive coronary artery disease, which is more prevalent in men. Data are needed on psychological predictors and other manifestations of IHD such as coronary microvascular disease, which is more common in women.

Health problems and care needs in patients with Korsakoff's syndrome: A systematic review

WHAT IS KNOWN ON THE SUBJECT?: Patients with Korsakoff's syndrome suffer from a broad range of comorbid somatic and/or psychiatric conditions. The various health problems in patients with Korsakoff's syndrome limit their ability to perform daily activities and also negatively affect their social functioning. WHAT THE PAPER ADDS TO EXISTING KNOWLEDGE?: Patients with Korsakoff's syndrome have complex somatic and psychiatric comorbid conditions co-occurring with behavioural and functional problems. They are compounded by patients' poor self-awareness regarding their health status and functioning. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: This review demonstrates that patients with Korsakoff's syndrome should receive integrated care. Integrated care for patients with Korsakoff's syndrome should be based on accurate multidimensional and multidisciplinary diagnostics in which nurses and nurse assistants have a prominent role due to their central position in the care process patients with Korsakoff's syndrome. ABSTRACT: Introduction The literature shows that Korsakoff's syndrome is associated with a wide range of severe comorbid somatic and psychiatric health problems that lead to care needs in several domains of functioning. Aim To provide a comprehensive overview of Korsakoff patients' health conditions and related care needs. Method Following the PRISMA guidelines, we searched MEDLINE, PsycInfo, Cochrane Library and CINAHL up to January 2019. After applying our inclusion criteria, two reviewers independently selected the studies, extracted the data and assessed methodological quality. Results Twelve articles were included. The commonest somatic comorbid conditions were liver disease, cardiovascular disease, COPD and diabetes mellitus. The commonest psychiatric comorbid conditions were mood disorder, personality disorder and psychotic disorder. Anxiety, aggressive/agitated behaviour, depressive symptoms and care needs in social functioning and (instrumental) activities of daily living were also very commonly reported. Discussion In patients with Korsakoff's syndrome, somatic and psychiatric comorbid conditions co-occur with behavioural and functional problems. They are compounded by patients' poor self-awareness regarding their health status and functioning. Adequate responses to their care needs require high-quality integrated care. Implications for practice Patients with Korsakoff's syndrome should receive integrated care based on accurate multidimensional and multidisciplinary diagnostics in which nurses have a prominent role.

European Psychiatric Association (EPA) guidance on quality assurance in mental healthcare

Purpose:

To advance the quality of mental healthcare in Europe by developing guidance on implementing quality assurance.

Methods:

We performed a systematic literature search on quality assurance in mental healthcare and the 522 retrieved documents were evaluated by two independent reviewers (B.J. and J.Z.). Based on these evaluations, evidence tables were generated. As it was found that these did not cover all areas of mental healthcare, supplementary hand searches were performed for selected additional areas. Based on these findings, fifteen graded recommendations were developed and consented by the authors. Review by the EPA Guidance Committee and EPA Board led to two additional recommendations (on immigrant mental healthcare and parity of mental and physical healthcare funding).

Results:

Although quality assurance (measures to keep a certain degree of quality), quality control and monitoring (applying quality indicators to the current degree of quality), and quality management (coordinated measures and activities with regard to quality) are conceptually distinct, in practice they are frequently used as if identical and hardly separable. There is a dearth of controlled trials addressing ways to optimize quality assurance in mental healthcare. Altogether, seventeen recommendations were developed addressing a range of aspects of quality assurance in mental healthcare, which appear usable across Europe. These were divided into recommendations about structures, processes and outcomes. Each recommendation was assigned to a hierarchical level of analysis (macro-, meso- and micro-level).

Discussion:

There was a lack of evidence retrievable by a systematic literature search about quality assurance of mental healthcare. Therefore, only after further topics and search had been added it was possible to develop recommendations with mostly medium evidence levels.

Conclusion:

Evidence-based graded recommendations for quality assurance in mental healthcare were developed which should next be implemented and evaluated for feasibility and validity in some European countries. Due to the small evidence base identified corresponding to the practical obscurity of the concept and methods, a European research initiative is called for by the stakeholders represented in this Guidance to improve the educational, methodological and empirical basis for a future broad implementation of measures for quality assurance in European mental healthcare.

Cardiac disease and stroke: Practical implications for personalised care in cardiac-stroke patients. A state of the art review supported by the Association of Cardiovascular Nursing and Allied Professions

Cardiac and stroke conditions often coexist because of common risk factors. The occurrence of stroke may have significant consequences for patients with cardiac conditions and their caregivers and poses a major burden on their lives. Although both cardiac and stroke conditions are highly prevalent, primary stroke prevention in cardiac patients is crucial to avert disabling limitations or even mortality. In addition, specific interventions may be needed in the rehabilitation and follow-up of these patients. However, healthcare systems are often fragmented and are not integrated enough to provide specifically structured and individualised management for the cardiac-stroke patient. Cardiac rehabilitation or secondary prevention services are crucial from this perspective, although referral and attendance rates are often suboptimal. This state of the art review outlines the significance of primary stroke prevention in cardiac patients, highlights specific challenges that cardiac-stroke patients and their caregivers may experience, examines the availability of and need for structured, personalised care, and describes potential implications for consideration in daily practice.

Is there a relationship between PTSD and complicated obesity? A review of the literature

Recent research strongly supports the hypothesis that posttraumatic stress disorder (PTSD) can be accompanied by obesity and related metabolic disturbances. The mechanisms of these associations are however still not well defined, although disturbed functions in the sympathetic-adrenergic nervous system together with the disturbed release of hormones via the endocrine HPA (hypothalamic-pituitary-adrenal) axis apparently play a role. Leptin resistance and ghrelin excesses might contribute to a disturbed hypothalamic function, and also disturb other cerebral functions, leading to dysfunctional reward signaling and uncontrolled appetite combined with a tendency to alcohol abuse. Secondarily, cortisol stimulation will contribute to the development of central obesity which is known to facilitate the development of metabolic syndrome, including slightly increased levels of inflammatory biomarkers such as C-reactive protein and fibrinogen. While previous therapeutic strategies have focused on early psychotherapeutic interventions in PTSD, the present review emphasizes the importance of better therapeutic approaches regarding the somatic correlates of the syndrome. Strict regulation of dietary meals and food composition with minimal intake of sweets and saturated fat, as well as alcohol avoidance, can provide a basic therapeutic framework. A cognitive psychotherapeutic approach with graduated desensitization toward trigging factors, combined with pharmacotherapy, is discussed in the present review.

Partitioning the Pleiotropy Between Coronary Artery Disease and Body Mass Index Reveals the Importance of Low Frequency Variants and Central Nervous System-Specific Functional Elements

BACKGROUND

The objective of this study is to investigate the extent and nature of pleiotropy between coronary artery disease (CAD) and body mass index (BMI).

METHODS

We examined the contribution of genome-wide single-nucleotide polymorphisms (minor allele frequency ≥0.01) to co-occurrence of CAD and BMI in a sample of genetically unrelated 8041 subjects (genetic resemblance ≤0.025) of European ancestry using mixed-linear-models. We further partitioned the estimated pleiotropy according to biological features to gain insight into the nature of pleiotropy between CAD and BMI.

RESULTS

We found significant (P<0.0001) positive genetic correlation between CAD and BMI (r_g =0.60). The estimated pleiotropy explained 68% of phenotypic correlation, and it was not proportionally distributed across the chromosomes; notably, chromosome 10 contributed more; whereas, chromosomes 11 and 14 contributed less to pleiotropy than expected given their chromosomal length. We noted that a large proportion (63%; P=0.002) of the pleiotropy is attributed to single-nucleotide polymorphisms with low allele frequency (minor allele frequency <0.05). Of note, pleiotropy was enriched among central nervous system genes and genes of metabolic pathways. Further analyses revealed that these effects are more pronounced in the proopiomelanocortin pathway and genes involved in carbohydrate metabolism. After genome-wide association study meta-analysis, only single-nucleotide polymorphisms downstream of the MC4R gene were found concordantly associated with (P<5×10^-8) BMI and CAD with lead single-nucleotide polymorphism being rs663129 (combined P=2.7×10^-65). Finally, partitioning the pleiotropy according to functional elements pointed to the importance of superenhancers and notably brain-specific superenhancers.

CONCLUSIONS

Genome-wide pleiotropy substantially contributes to co-occurrence of CAD and obesity, and it is highly enriched among low frequency variants and central nervous system-specific functional elements.

Evaluating Longitudinal Associations Between Depressive Symptoms, Smoking, and Biomarkers of Cardiovascular Disease in the CARDIA Study

OBJECTIVE

The aim of the study was to evaluate associations between 15-year trajectories of co-occurring depressive symptoms and smoking with biomarkers of cardiovascular disease at year 15.

METHODS

In the Coronary Artery Risk Development in Young Adults study, we modeled trajectories of depressive symptoms (Center for Epidemiologic Studies-Depression scale [CES-D]) and smoking (cigarettes per day [CPD]) among 3614 adults followed from year 0 (ages 18-30 years) through year 15 (ages 33-45 years). Biomarkers of inflammation (high-sensitivity C-reactive protein), oxidative stress (superoxide dismutase, F2-isoprostanes), and endothelial dysfunction (soluble intercellular adhesion molecule 1, soluble P-selectin) were assessed at year 15. We conducted separate linear regression analyses with CES-D trajectory, CPD trajectory, and their interaction with each of the five biomarkers.

RESULTS

The sample was 56% women, 47% black, and 40 years old on average at year 15. The CES-D trajectory by CPD trajectory interaction was not associated with any of the biomarkers (all p's > .01). Removing the interaction term, CES-D trajectory was associated with inflammation: higher levels of high-sensitivity C-reactive protein were observed in the subthreshold (β = 0.57, p = .004) and increasing depressive symptoms (β = 1.36, p < .001) trajectories compared with the no depression trajectory. CPD trajectory was associated with oxidative stress and endothelial dysfunction: compared with never smokers, heavy smokers had significantly higher levels of F2-isoprostanes (β = 6.20, p = .001), soluble intercellular adhesion molecule 1 (β = 24.98, p < .001), and soluble P-selectin (β = 2.91, p < .001).

CONCLUSIONS

Co-occurring depressive symptoms and smoking do not seem to synergistically convey risk for cardiovascular disease via processes of inflammation, oxidative stress, or endothelial dysfunction. Nonetheless, these results advance our understanding of the complex relationships between modifiable risk factors and chronic disease.

Enhanced psychological care in cardiac rehabilitation services for patients with new-onset depression: the CADENCE feasibility study and pilot RCT

BACKGROUND

Around 19% of people screened by UK cardiac rehabilitation programmes report having moderate or severe symptoms of depression. These individuals are at an increased risk of cardiac mortality and morbidity, reduced quality of life and increased use of health resources compared with their non-depressed counterparts. Maximising psychological health is a goal of cardiac rehabilitation, but psychological care is patchy.

OBJECTIVE(S)

To examine the feasibility and acceptability of embedding enhanced psychological care (EPC) within cardiac rehabilitation, we tested the feasibility of developing/implementing EPC and documented the key uncertainties associated with undertaking a definitive evaluation.

DESIGN

A two-stage multimethods study; a feasibility study and a qualitative evaluation, followed by an external pilot cluster randomised controlled trial (RCT) with a nested qualitative study.

SETTING

UK comprehensive cardiac rehabilitation teams.

PARTICIPANTS

Adults eligible for cardiac rehabilitation following an acute coronary syndrome with new-onset depressive symptoms on initial nurse assessment. Patients who had received treatment for depression in the preceding 6 months were excluded.

INTERVENTIONS

The EPC intervention comprised nurse-led mental health-care co-ordination and behavioural activation within cardiac rehabilitation. The comparator was usual cardiac rehabilitation care.

MAIN OUTCOME MEASURES

Measures at baseline, and at the 5- (feasibility and pilot) and 8-month follow-ups (pilot only). Process measures related to cardiac team and patient recruitment, and participant retention. Outcomes included depressive symptoms, cardiac mortality and morbidity, anxiety, health-related quality of life and service resource use. Interviews explored participant and nurses' views and experiences.

RESULTS

Between September 2014 and May 2015, five nurses from four teams recruited participants into the feasibility study. Of the 203 patients screened, 30 were eligible and nine took part (the target was 20 participants). At interview, participants and nurses gave valuable insights into the EPC intervention design and delivery. Although acceptable, the EPC delivery was challenging for nurses (e.g. the ability to allocate sufficient time within existing workloads) and the intervention was modified accordingly. Between December 2014 and February 2015, 8 out of 20 teams approached agreed to participate in the pilot RCT [five were randomised to the EPC arm and three were randomised to the usual-care (UC) arm]. Of the 614 patients screened, 55 were eligible and 29 took part (the target was 43 participants). At baseline, the trial arms were well matched for sex and ethnicity, although the EPC arm participants were younger, from more deprived areas and had higher depression scores than the UC participants. A total of 27 out of 29 participants were followed up at 5 months. Interviews with 18 participants (12 in the EPC arm and six in the UC arm) and seven nurses who delivered EPC identified that both groups acknowledged the importance of receiving psychological support embedded within routine cardiac rehabilitation. For those experiencing/delivering EPC, the intervention was broadly acceptable, albeit challenging to deliver within existing care.

LIMITATIONS

Both the feasibility and the pilot studies encountered significant challenges in recruiting patients, which limited the power of the pilot study analyses.

CONCLUSIONS

Cardiac rehabilitation nurses can be trained to deliver EPC. Although valued by both patients and nurses, organisational and workload constraints were significant barriers to implementation in participating teams, suggesting that future research may require a modified approach to intervention delivery within current service arrangements. We obtained important data informing definitive research regarding participant recruitment and retention, and optimal methods of data collection.

FUTURE RESEARCH

Consideration should be given to the delivery of EPC by dedicated mental health practitioners, working closely with cardiac rehabilitation services.

Associations between depression, anxiety and medication adherence among patients with arterial hypertension: Comparison between persons exposed and non-exposed to radiation from the Semipalatinsk Nuclear Test Site

In this study, we investigated the association between depression, anxiety and medication adherence in patients with arterial hypertension living in East Kazakhstan region. The sample size included 795 patients, of whom 403 patients were exposed to radiation at the Semipalatinsk Nuclear Test Site from 1949 to 1989, while 395 patients were unexposed to radiation due to their very remote residence from the Site at the same period. Both exposed and unexposed patients showed no significant differences concerning body mass index, smoking habit, the presence of hypercholesterolemia, and hypertension grade. Patients with arterial hypertension previously exposed to radiation had significantly higher rates of low medication adherence, subclinical and clinical depression, situational anxiety of moderate and severe grade, and personal anxiety of moderate grade. A logistic regression analysis allowed us to identify the presence of significant positive association between medication adherence and anxiety in exposed patients (OR = 4041 (95%CI:1709-9556) p = 0.001) and marginal association (OR = 2998 (95%CI:1008-8915) p = 0.048) between the same parameters in unexposed patients. It might prove to be useful to introduce psychological and medical counseling with an emphasis on strengthening of medication adherence and to inform the local population about radiation effects and dosimetry data.

The intriguing relationship between coronary heart disease and mental disorders

Coronary heart disease (CHD) and mental illness are among the leading causes of morbidity and mortality worldwide. Decades of research has revealed several, and sometimes surprising, links between CHD and mental illness, and has even suggested that both may actually cause one another. However, the precise nature of these links has not yet been clearly established. The goal of this paper, therefore, is to comprehensively review and discuss the state-of-the-art nature of the epidemiological and pathophysiological aspects of the bidirectional links between mental illness and CHD. This review demonstrates that there exists a large body of epidemiological prospective data showing that people with severe mental illness, including schizophrenia, bipolar disorder, and major depressive disorder, as a group, have an increased risk of developing CHD, compared with controls [adjusted hazard ratio (adjHR)=1.54; 95% CI: 1.30-1.82, P<0.0001]. Anxiety symptoms or disorders (Relative Risk (RR)=1.41, 95% CI: 1.23-1.61, P<0.0001), as well as experiences of persistent or intense stress or posttraumatic stress disorder (PTSD) (adjHR=1.27, 95% CI: 1.08-1.49), although to a lesser degree, may also be independently associated with an increased risk of developing CHD. On the other hand, research also indicates that these symptoms/mental diseases are common in patients with CHD and may be associated with a substantial increase in cardiovascular morbidity and mortality. Finally, mental diseases and CHD appear to have a shared etiology, including biological, behavioral, psychological, and genetic mechanisms.

Women's Health in the Lund Area (WHILA) study. Health problems and acute myocardial infarction in women - A 17-year follow-up study

OBJECTIVES

The literature has highlighted the importance of identifying symptoms predictive of acute myocardial infarction (AMI) in women, in addition to traditional cardiovascular risk factors. The objective was to study subjective health problems, in relation to later AMI, in a large sample of women, adjusted for age, educational status, smoking, waist/hip ratio, blood pressure, total cholesterol/HDL ratio, diabetes and neighbourhood socioeconomic status.

STUDY DESIGN

From December 1995 to February 2000 a cohort of 6711 women aged 50-59 years in southern Sweden underwent a physical examination and answered a questionnaire that had 18 items on health problems such as stress symptoms, tiredness and pain.

MAIN OUTCOME MEASURES

Incidence of AMI during a mean follow-up of 17 years, drawn from national registers.

RESULTS

The number of health problems showed a J-shaped relationship with AMI, with the lowest hazard ratio (HR) in women with a median of 4 health problems. The HR for AMI in women with 0 health problems was 1.58 (95% CI: 0.95-2.63) and in those with 13 problems HR 1.65 (95% CI 1.16-2.36), after adjusting for potential confounding factors.

CONCLUSIONS

The presence of several health problems, including pain and stress symptoms, is associated with an increased risk of later AMI in middle-aged women. Awareness among clinicians of predictive risk factors for AMI is important for the early identification of individuals at higher risk.

Associations of mental health with cardiovascular risk phenotypes and adiposity in adolescence: A cross-sectional community-based study

AIM

Cardiovascular disease and mental illness commonly co-occur in later life, but it is unknown how early these associations arise. We aimed to determine the extent to which: (i) childhood mental health is associated with functional and structural cardiovascular risk phenotypes and adiposity in late childhood/adolescence, and (ii) associations between mental health and cardiovascular phenotypes may be explained by differential body mass index.

METHODS

This cross-sectional study drew on three longitudinal community-based cohort studies (two enriched for overweight/obesity) in metropolitan Melbourne, Australia, with harmonized follow-up in 2014. Mental health exposures included emotional and behavioural problems (Strength and Difficulties Questionnaire) and psychosocial health and general well-being (Pediatric Quality of Life Inventory (PedsQL)), which were assessed by self- and parent-proxy report. Cardiovascular risk phenotypes and adiposity measures included mean arterial pressure, pulse wave velocity, carotid artery intima-media thickness, retinal arterioleto-venule ratio, waist circumference, % body fat, and BMI z-score. We used multivariable linear regression models, adjusting for age, sex and neighbourhood disadvantage, to examine associations.

RESULTS

Of the 364 participants (mean age 14.7, standard deviation 2.0, years), 30% were overweight and 16% obese. All adiposity indicators were positively associated with higher behavioural/emotional problems and poorer psychosocial health and negatively associated with better ratings of positive general well-being, as reported by parents and children (all P ≤ 0.03). However, there was little evidence that cardiovascular functional or structural phenotypes varied by mental health.

CONCLUSIONS

By late childhood/adolescence, mental health is strongly associated with adiposity but not with cardiovascular structure or function. This suggests that the known relationship between these constructs may not develop until early or mid-adulthood.

Psychosocial perspectives in cardiovascular disease

Adaptation to living with cardiovascular disease may differ from patient to patient and is influenced not only by disease severity and limitations incurred by the disease but also by socioeconomic factors (e.g. health literacy), the patients' psychological make-up and susceptibility to distress. Co-morbid depression and/or anxiety is prevalent in 20% of patients with cardiovascular disease, which may be either transient or chronic. Distress, such as depression, reduces adherence, serves as a barrier to behaviour change and the adoption of a healthy lifestyle, and increases the risk that patients drop out of cardiac rehabilitation, impacting on patients' quality of life, risk of hospitalisation and mortality. Hence it is paramount to identify this subset of high-risk patients in clinical practice. This review provides a general overview of the prevalence of selected psychosocial risk factors, their impact on patient-reported and clinical outcomes, and biological and behavioural mechanisms that may explain the association between psychosocial factors and health outcomes. The review also provides recommendations on which self-report screening measures to use to identify patients at high risk due to their psychosocial profile, and the effectiveness of available trials that target these risk factors. Despite challenges and barriers associated with screening of patients combined with appropriate treatment, it is paramount that we treat not only the heart but also the mind in order to improve the quality of care and patient and clinical outcomes.

Assessing the effectiveness of Enhanced Psychological Care for patients with depressive symptoms attending cardiac rehabilitation compared with treatment as usual (CADENCE): a pilot cluster randomised controlled trial

BACKGROUND

Around 17% of people attending UK cardiac rehabilitation programmes have depression. Optimising psychological wellbeing is a rehabilitation goal, but provision of psychological care is limited. We developed and piloted an Enhanced Psychological Care (EPC) intervention embedded within cardiac rehabilitation, aiming to test key areas of uncertainty to inform the design of a definitive randomised controlled trial (RCT) and economic evaluation.

METHODS

An external pilot randomised controlled trial (RCT) randomised eight cardiac rehabilitation teams (clusters) to either usual care of cardiac rehabilitation provision (UC), or EPC in addition to UC. EPC comprised mental health care coordination and patient-led behavioural activation with nurse support. Adults eligible for cardiac rehabilitation following an acute coronary syndrome and identified with new-onset depressive symptoms during an initial nurse assessment were eligible. Measures were performed at baseline and 5- and 8-month follow-ups and compared between EPC and UC. Team and participant recruitment and retention rates, and participant outcomes (clinical events, depression, anxiety, health-related quality of life, patient experiences, and resource use) were assessed.

RESULTS

Eight out of twenty teams were recruited and randomised. Of 614 patients screened, 55 were eligible and 29 took part (5%, 95% CI 3 to 7% of those screened), with 15 patient participants cluster randomised to EPC and 14 to UC. Nurse records revealed that 8/15 participants received the maximum number of EPC sessions offered; and 4/15 received no sessions. Seven out of fifteen EPC participants were referred to another NHS psychological service compared to none in UC. We followed up 27/29 participants at 5 months and 17/21 at 8 months. The mean difference (EPC minus UC) in depressive symptoms (Beck Depression Inventory) at follow-up (adjusting for baseline score) was 1.7 (95% CI - 3.8 to 7.3; N = 26) at 5 months and 4.4 (95% CI - 1.4 to 10.2; N = 17) at 8 months.

DISCUSSION

While valued by patients and nurses, organisational and workload constraints are significant barriers to EPC implementation. There remains a need to develop and test new models of psychological care within cardiac rehabilitation. Our study offers important data to inform the design of future trials of similar interventions.

Cause-specific mortality in Swedish males diagnosed with non-psychotic mental disorders in late adolescence: a prospective population-based study

BACKGROUND

While risk of premature death is most pronounced among persons with severe mental illness, also milder conditions are associated with increased all-cause mortality. We examined non-psychotic mental (NPM) disorders and specific causes of natural death in a cohort of late adolescent men followed for up to 46 years.

METHODS

Prospective cohort study of Swedish males (n=1 784 626) who took part in structured conscription interviews 1968-2005. 74 525 men were diagnosed with NPM disorders at or prior to conscription. Median follow-up time was 26 years. HRs for cause-specific mortality were calculated using Cox proportional hazards models.

RESULTS

Risks in fully adjusted models were particularly elevated for death by infectious diseases (depressive and neurotic/adjustment disorders (HR 2.07; 95% CI 1.60 to 2.67), personality disorders (HR 2.90; 95% CI 1.96 to 4.28) and alcohol-related and other substance use disorders (HR 9.02; 95% CI 6.63 to 12.27)) as well as by gastrointestinal causes (depressive and neurotic/adjustment disorders (HR 1.64; 95% CI 1.42 to 1.89), personality disorders (HR 2.77; 95% CI 2.27 to 3.38) and alcohol-related/substance use disorders (HR 4.41; 95% CI 3.59 to 5.42)).

CONCLUSION

Young men diagnosed with NPM disorders had a long-term increased mortality risk, in particular due to infectious and gastrointestinal conditions. These findings highlight the importance of early preventive actions for adolescents with mental illness.

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

Background

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

Design

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

Methods

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

Results

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

Conclusions

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

Management of serious cardiac adverse effects of antipsychotic medications

The use of antipsychotic medications has now expanded to multiple mental health conditions beyond schizophrenia. This has increased the overall population exposure to these medications, which have been associated with both metabolic changes and adverse cardiovascular effects. QTc prolongation, torsades de pointes, sudden cardiac death, myocarditis, and cardiomyopathy are all very real concerns that clinicians face on a regular basis. One must take these risks into consideration when selecting antipsychotic therapy and also when determining whether therapeutic changes and adjustments are necessary. This review examines a number of cardiac-associated concerns, the role that antipsychotics may play in contributing to these adverse events, and suggested management interventions.

Patients' and nurses' views on providing psychological support within cardiac rehabilitation programmes: a qualitative study

OBJECTIVE

To explore patients' and nurses' views on the feasibility and acceptability of providing psychological care within cardiac rehabilitation services.

DESIGN

In-depth interviews analysed thematically.

PARTICIPANTS

18 patients and 7 cardiac nurses taking part in a pilot trial (CADENCE) of an enhanced psychological care intervention delivered within cardiac rehabilitation programmes by nurses to patients with symptoms of depression.

SETTING

Cardiac services based in the South West of England and the East Midlands, UK.

RESULTS

Patients and nurses viewed psychological support as central to good cardiac rehabilitation. Patients' accounts highlighted the significant and immediate adverse effect a cardiac event can have on an individual's mental well-being. They also showed that patients valued nurses attending to both their mental and physical health, and felt this was essential to their overall recovery. Nurses were committed to providing psychological support, believed it benefited patients, and advocated for this support to be delivered within cardiac rehabilitation programmes rather than within a parallel healthcare service. However, nurses were time-constrained and found it challenging to provide psychological care within their existing workloads.

CONCLUSIONS

Both patients and nurses highly value psychological support being delivered within cardiac rehabilitation programmes but resource constraints raise barriers to implementation. Consideration, therefore, should be given to alternative forms of delivery which do not rely solely on nurses to enable patients to receive psychological support during cardiac rehabilitation.

Psychological interventions for coronary heart disease

BACKGROUND

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

OBJECTIVES

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

SEARCH METHODS

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

SELECTION CRITERIA

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

DATA COLLECTION AND ANALYSIS

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

MAIN RESULTS

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

AUTHORS' CONCLUSIONS

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