Selected psychological comorbidities in coronary heart disease: Challenges and grand opportunities

Triglyceride-glucose index as a potential predictor of major adverse cardiovascular and cerebrovascular events in patients with coronary heart disease complicated with depression

Background

Triglyceride-glucose (TyG) index is a surrogate marker of insulin resistance and metabolic abnormalities, which is closely related to the prognosis of a variety of diseases. Patients with both CHD and depression have a higher risk of major adverse cardiovascular and cerebrovascular events (MACCE) and worse outcome. TyG index may be able to predict the adverse prognosis of this special population.

Methods

The retrospective cohort study involved 596 patients with both CHD and depression between June 2013 and December 2023. The primary outcome endpoint was the occurrence of MACCE, including all-cause death, stroke, MI and emergent coronary revascularization. The receiver operating characteristic (ROC) curve, Cox regression analysis, Kaplan-Meier survival analysis, and restricted cubic spline (RCS) analysis were used to assess the correlation between TyG index and MACCE risk of in patients with CHD complicated with depression.

Results

With a median follow-up of 31 (15-62) months, MACCE occurred in 281(47.15%) patients. The area under the ROC curve of TyG index predicting the risk of MACCE was 0.765(0.726-0.804) (P<0.01). Patients in the high TyG index group(69.73%) had a significantly higher risk of developing MACCE than those in the low TyG index group(23.63%) (P<0.01). The multifactorial RCS model showed a nonlinear correlation (nonlinear P<0.01, overall P<0.01), with a critical value of 8.80 for the TyG index to predict the occurrence of MACCE. The TyG index was able to further improve the predictive accuracy of MACCE.

Conclusions

TyG index is a potential predictor of the risk of MACCE in patients with CHD complicated with depression.

Research status of pathogenesis of anxiety or depression after percutaneous coronary intervention and Traditional Chinese Medicine intervention

ETHNIC PHARMACOLOGICAL RELEVANCE

Anxiety or depression after percutaneous coronary intervention (PCI) is a common clinical disease. Currently, conventional pharmacotherapy primarily involves the administration of anxiolytic or antidepressant medications in conjunction with anticoagulants, antiplatelet agents, and other cardiovascular drugs. However, challenges such as drug dependence, adverse reactions and related concerns persist in the treatment of this disease. Numerous pertinent studies have demonstrated that Traditional Chinese Medicine (TCM) exhibits significant therapeutic efficacy and distinctive advantages in managing post-PCI anxiety or depression.

AIM OF THIS REVIEW

This review attempted to summarize the characteristics of TCM for treating anxiety or depression after PCI, including single Chinese herbs, Chinese medicine monomers, compound TCM prescriptions, TCM patented drugs, and other TCM-related treatment methods, focusing on the analysis of the relevant mechanism of TCM treatment of this disease.

METHODS

By searching the literature on treating anxiety or depression after PCI with TCM in PubMed, Web of Science, CNKI, and other relevant databases, this review focuses on the latest research progress of TCM treatment of this disease.

RESULTS

In the treatment of anxiety or depression after PCI, TCM exerts significant pharmacological effects such as anti-inflammatory, antioxidant, anti-anxiety or anti-depression, cardiovascular and cerebrovascular protection, and neuroprotection, mainly by regulating the levels of related inflammatory factors, oxidative stress markers, neurotransmitter levels, and related signaling pathways. TCM has a good clinical effect in treating anxiety or depression after PCI with individualized treatment.

CONCLUSIONS

TCM has terrific potential and good prospects in the treatment of anxiety or depression after PCI. The main direction of future exploration is the study of the mechanism related to Chinese medicine monomers and the large sample clinical study related to compound TCM prescriptions.

Role of Brain-Derived Neurotrophic Factor in Anxiety or Depression After Percutaneous Coronary Intervention

Anxiety or depression after percutaneous coronary intervention (PCI) is one of the key clinical problems in cardiology that need to be solved urgently. Brain-derived neurotrophic factor (BDNF) may be a potential biomarker for the pathogenesis and treatment of anxiety or depression after PCI. This article reviews the correlation between BDNF and cardiovascular system and nervous system from the aspects of synthesis, release and action site of BDNF, and focuses on the latest research progress of the mechanism of BDNF in anxiety or depression after PCI. It includes the specific mechanisms by which BDNF regulates the levels of inflammatory factors, reduces oxidative stress damage, and mediates multiple signaling pathways. In addition, this review summarizes the therapeutic potential of BDNF as a potential biomarker for anxiety or depression after PCI.

PTSD, Comorbidities, Gender, and Increased Risk of Cardiovascular Disease in a Large Military Cohort

Importance

Posttraumatic stress disorder (PTSD) is a prevalent mental health problem that increases risk of cardiovascular disease (CVD). It is not known whether gender or comorbidities modify associations between PTSD and CVD.

Objective

To assess risk of hypertension and atherosclerotic CVD (ASCVD) associated with PTSD in a predominantly young military population, and determine if gender or PTSD comorbidities modify these associations.

Design setting and participants

Using administrative medical records, this longitudinal, retrospective cohort study assessed relationships of PTSD, gender, comorbidities (metabolic risk factors [MRF], behavioral risk factors [BRF], depression, and sleep disorders) to subsequent hypertension and ASCVD among 863,993 active-duty U.S. Army enlisted soldiers (86.2% male; 93.7%

Main outcomes and measures

ICD-9-CM diagnoses of hypertension, ASCVD (coronary artery disease, myocardial infarction, stroke, heart failure), PTSD, MRF (Type 2 diabetes, obesity), BRF (tobacco/alcohol use disorders), depression, and sleep disorders.

Results

PTSD was associated with subsequent hypertension (OR=3.0 [95% CI=2.9-3.1]), and ASCVD (OR=2.7 [95% CI=2.2-3.3]). These associations remained significant but were attenuated after adjusting for comorbidities and sociodemographic/service-related variables (Hypertension: OR=1.9 [95% CI=1.8-2.0]; ASCVD: OR=1.4 [95% CI=1.2-1.8]). For hypertension, gender and each comorbidity were significant explanatory variables in multivariable models, and there were significant PTSD interactions with gender, MRF, depression, and sleep disorders. Stratifying separately by gender and presence of each comorbidity, PTSD-hypertension associations were stronger among men, those without MRF, without depression, and without sleep disorders. Standardized risk estimates indicated that predicted hypertension rates for those with vs. without PTSD were higher for men, and for those with vs. without MRF, depression, and sleep disorders. For ASCVD, comorbidities, but not gender, were independent predictors, and associations between PTSD and ASCVD were not modified by gender or comorbidities.

Conclusions and relevance

PTSD and comorbidities are independent risk factors for hypertension and ASVD in younger individuals, and gender and comorbid conditions modify PTSD relationships with hypertension. These findings suggest that CVD preventive interventions address PTSD and medical and behavioral comorbidities.

Analysis of sleep for the American population: Result from NHANES database

OBJECTIVES

To assess the contemporary prevalence and decade-long trends of sleep duration, sleep disorders and trouble sleeping among adults in the United States, as well as their risk factors, from 2005 to 2018.

MATERIALS AND METHODS

We used National Health and Nutrition Examination Survey data to calculate the sleep duration and weighted prevalence of sleep disorders and trouble sleeping in adults aged 20 years or older. Sleep duration, sleep disorders and trouble sleeping were assessed by questionnaire.

RESULTS

A total of 27,399 people were included in the survey on sleep duration, with a weighted percentage of normal sleep (7-8 h/night) of 56.33 % (95 % CI, 53.06-59.60 %) and a weighted percentage of short sleep (5-6 h/night) of 31.73 %. In stratified descriptions, participants aged 40-49 years were more likely to sleep less than five hours, while women aged 80 years and older were more likely to sleep longer and blacks were more likely to sleep shorter. A total of 27,406 participants were included in the survey for sleep disorders. The weighted proportion of the population with sleep disorders was 8.44 % (95 % CI, 7.79-9.8 %). Independent risk factors for sleep disorders were being 40-69 years old, being white, having a high education level, smoking, having hypertension, diabetes, heart disease, and BMI ≥ 25. From 2005 to 2014, the prevalence of sleep disorders increased year by year, from 7.44 % in 2005-2006 to 10.40 % in 2013-2014 (P for Trend<0.001). A total of 38,165 participants were included in the survey on trouble sleeping. The weighted proportion of the population with troubled sleeping was 27.30 % (25.70-28.90 %). Independent risk factors for troubled sleeping were being 30-79 years old, being white, having a high education level, smoking, drinking, having hypertension, diabetes, heart disease and BMI ≥ 25. From 2005 to 2018, the prevalence of trouble sleeping increased annually, from 24.44 % in 2005-2006 to 30.58 % in 2017-2018 (P for trend<0.001).

CONCLUSION

Adults in the United States are likely to have abnormal sleep durations, and the prevalence of sleep disorders and troubled sleeping is on the rise.

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

BACKGROUND

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

OBJECTIVES

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

Exploring the relationship between vitamin D deficiency and comorbid heart disease in Americans with mood disorders: a cross-sectional nationwide study

Objective

This study aimed to explore the relationship between vitamin D deficiency and comorbid heart disease in adult inpatients with mood disorders (depressive and bipolar disorders).

Methods

A cross-sectional investigation was carried out employing the nationwide inpatient dataset, which encompassed 910,561 adult inpatients aged 18 to 50 years diagnosed with depressive and bipolar disorders. Additionally, the sample was categorized based on the presence of comorbid heart disease. We utilized a logistic regression model to assess the odds ratio (OR), pertaining to demographic features and coexisting medical conditions in relation to comorbid heart disease.

Results

Comorbid heart disease was present in 1.3% of inpatients with mood disorders; they were middle-aged (mean age 42.7 years) men and White individuals. Inpatients with depressive disorder had a higher risk of comorbid heart disease (OR 1.19, 95% CI 1.15-1.24) compared to those with bipolar disorders. Inpatients with comorbid heart disease had a higher prevalence of medical and psychiatric comorbidities. The prevalence of vitamin D deficiency was 2.3% in mood disorders but higher in those with comorbid heart disease (2.9%). Vitamin D deficiency showed a notable correlation with comorbid heart disease, resulting in a 26% increased risk in the unadjusted regression model (OR 1.26, 95% CI 1.13-1.40). However, after accounting for potential confounding factors, including comorbidities, the risk did not exhibit statistical significance (OR 1.08, 95% CI 0.97-1.21). Among psychiatric comorbidities, trauma-related (OR 1.22, 95% CI 1.17-1.28) and tobacco-related (OR 1.31, 95% CI 1.26-1.37) disorders had a higher risk of association with comorbid heart disease.

Conclusion

Middle-aged men with depressive disorders and from low-income families had a higher risk of developing comorbid heart disease. Trauma-related and tobacco-related disorders were associated with an increased risk by 20-30% for comorbid heart disease in inpatients with mood disorders. Vitamin D deficiency was not associated with the risk of comorbid heart disease after controlling demographics and comorbid cardiovascular risk factors.

Sex Differences in Patient-Reported Outcomes in the Immediate Recovery Period After Resuscitation: Findings From the Cross-sectional DenHeart Survey

BACKGROUND

A paucity of resuscitation studies have examined sex differences in patient-reported outcomes upon hospital discharge. It remains unclear whether male and female patients differ in health outcomes in their immediate responses to trauma and treatment after resuscitation.

OBJECTIVES

The aim of this study was to examine sex differences in patient-reported outcomes in the immediate recovery period after resuscitation.

METHODS

In a national cross-sectional survey, patient-reported outcomes were measured by 5 instruments: symptoms of anxiety and depression (Hospital Anxiety and Depression Scale), illness perception (Brief Illness Perception Questionnaire [B-IPQ]), symptom burden (Edmonton Symptom Assessment Scale [ESAS]), quality of life (Heart Quality of Life Questionnaire), and perceived health status (12-Item Short Form Survey).

RESULTS

Of 491 eligible survivors of cardiac arrest, 176 (80% male) participated. Compared with male, resuscitated female reported worse symptoms of anxiety (Hospital Anxiety and Depression Scale-Anxiety score ≥8) (43% vs 23%; P = .04), emotional responses (B-IPQ) (mean [SD], 4.9 [3.12] vs 3.7 [2.99]; P = .05), identity (B-IPQ) (mean [SD], 4.3 [3.10] vs 4.0 [2.85]; P = .04), fatigue (ESAS) (mean [SD], 5.26 [2.48] vs 3.92 [2.93]; P = .01), and depressive symptoms (ESAS) (mean [SD], 2.60 [2.68] vs 1.67 [2.19]; P = .05).

CONCLUSIONS

Between sexes, female survivors of cardiac arrest reported worse psychological distress and illness perception and higher symptom burden in the immediate recovery period after resuscitation. Attention should focus on early symptom screening at hospital discharge to identify those in need of targeted psychological support and rehabilitation.

Efficacy and safety of Shugan Jieyu Decoction in the treatment of coronary heart disease complicated with depression

BACKGROUND

Coronary heart disease combined with depression is 1 of the 2 major diseases affecting physical and mental health. It has become a hot spot at the intersection of psychiatry and internal medicine. Most doctors call double heart medicine, which has a high incidence rate and a low diagnostic rate. Clinical research shows that Shugan Jieyu Decoction (SJD) has a better curative effect, increased safety, and fewer adverse reactions, but it lacks systematic evaluation. This study aims to integrate clinical data through network meta-analysis and provide more evidence-based medical evidence for clinical medication.

METHODS

We searched 8 electronic databases: China knowledge network database, Wanfang, VIP, SinoMed, PubMed, Embase, WebofScience, Cochrane Library, and selected 22 randomized controlled trials from January 2012 to January 2022. The common primary endpoint was the relief of angina pectoris and the improvement of depression. Two researchers used Endnote9.1 software to conduct literature screening and information extraction according to the developed nano-passage standard, used Cochrane collaborative tool to evaluate the bias risk in the experiment, and then used RevMan5.3 software to assess the literature and data analysis synthesis.

RESULTS

In 1908 patients with coronary heart disease and depression, the total effective rate of SJD in the treatment of angina pectoris was 3.49 (95% confidence interval, 1.93-6.29), as well as the network meta-analysis of improving depressive symptoms, anxiety, depression scores (SAS, SDS) and quality of life scores (HAMD), and reducing the indicators related to CPR and homocysteine.

CONCLUSION

The analysis of this study shows that SJD can reduce the frequency of angina pectoris in patients with coronary heart disease and depression, alleviate anxiety and depression, provide a reference basis for clinical treatment, and select more effective intervention therapy.

Primary care patients with cardiovascular disease eligible for nurse-led internet-based cognitive behavioural therapy for insomnia: Characteristics and motives for participation

AIM

To describe demographic, physical and psychological characteristics associated with insomnia in patients with cardiovascular disease (CVD) participating in nurse-led Internet-based cognitive behavioural therapy for insomnia (I-CBTI), and their motives and expectations regarding participation in I-CBTI.

DESIGN

A mixed method design was applied, including primary care patients with angina pectoris, myocardial infarction, heart failure, atrial fibrillation and atrial flutter or arrhythmia in southern Sweden.

METHODS

Data on demographics, insomnia severity and physical and psychological characteristics were collected through self-rated validated questionnaires (n = 126). Motives and expectations were collected through interviews (n = 19) and analysed using the 'personas' model.

RESULTS

Physical symptoms and psychological characteristics were associated with insomnia. Three personas were identified: the pragmatist (a curious and optimistic persona), the philosopher (a problem-solving persona) and the philanthropist (an altruistic persona). Expectations were positive among the three personas, but comorbid conditions reduced the perceived ability to make necessary behavioural changes.

Prevalence of Mental, Behavioral, and Developmental Disorders Among Children and Adolescents with Diabetes, United States (2016-2019)

OBJECTIVE

To assess the association of diabetes and mental, behavioral, and developmental disorders in youth, we examined the magnitude of overlap between these disorders in children and adolescents.

STUDY DESIGN

In this cross-sectional study, we calculated prevalence estimates using the 2016-2019 National Survey of Children's Health. Parents reported whether their child was currently diagnosed with diabetes or with any of the following mental, behavioral, or developmental disorders: attention-deficit/hyperactivity disorder, autism spectrum disorder, learning disability, intellectual disability, developmental delay, anxiety, depression, behavioral problems, Tourette syndrome, or speech/language disorder. We present crude prevalence estimates weighted to be representative of the US child population and adjusted prevalence ratios (aPRs) adjusted for age, sex, and race/ethnicity.

RESULTS

Among children and adolescents (aged 2-17 years; n = 121 312), prevalence of mental, behavioral, and developmental disorders varied by diabetes status (diabetes: 39.9% [30.2-50.4]; no diabetes: 20.3% [19.8-20.8]). Compared with children and adolescents without diabetes, those with diabetes had a nearly 2-fold higher prevalence of mental, behavioral, and developmental disorders (aPR: 1.72 [1.31-2.27]); mental, emotional, and behavioral disorders (aPR: 1.90 [1.38-2.61]) and developmental, learning, and language disorders (aPR: 1.89 [1.35-2.66]).

CONCLUSIONS

These results suggest that approximately 2 in 5 children and adolescents with diabetes have a mental, behavioral, or developmental disorder. Understanding potential causal pathways may ultimately lead to future preventative strategies for mental, behavioral, and developmental disorders and diabetes in children and adolescents.

microRNA-181c-5p stimulates the development of coronary artery disease by targeting SIRT1

OBJECTIVE

MicroRNA (miR) therapeutics is a promising approach to manage coronary artery disease (CAD). Herein, this research was aimed to explore miR-181c-5p-related mechanisms in CAD through regulating SIRT1.

METHODS

A CAD mouse model was established by feeding a high-fat diet in 8-week-old ApoE^-/- mice. miR-181c-5p, SIRT1, and acetylated p65 levels in mouse myocardial tissues were evaluated by RT-qPCR and Western blot. Hemodynamic parameters included the maximum rising rate of the left ventricular pressure (lv + dp/dtmax) and the time values from the onset of contraction to dp/dtmax (t-dp/dtmax), while hemorheological indices included whole blood viscosity (low shear, middle shear, or high shear), plasma viscosity, hematocrit, and platelet adhesion were measured. Tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and IL-6 were detected. Mouse pathological changes, degree of fibrosis, and cardiomyocyte apoptosis in myocardial tissues were assessed by HE, Masson, and TUNEL staining, respectively. The targeting relationship between miR-181c-5p and SIRT1 was verified by bioinformatics tools, dual luciferase reporter gene assay, and RNA pull-down assays.

RESULTS

In myocardial tissue of CAD mice, miR-181c-5p and acetylated p65 were upregulated while SIRT1 was downregulated. Downregulating miR-181c-5p or upregulating SIRT1 effectively ameliorated CAD by improving hemodynamics and hemorheology and reducing inflammation, pathological changes, degree of fibrosis, and cardiomyocyte apoptosis in myocardial tissues of mice. miR-181c-5p targeted SIRT1, and overexpression of SIRT1 relieved upregulated miR-181c-5p-induced injuries in CAD mice. Regulating miR-181c-5p and SIRT1 affected the acetylation of p65.

CONCLUSION

Downregulation of miR-181c-5p may ameliorate myocardial pathological changes and cardiomyocyte apoptosis in CAD by upregulating SIRT1 expression and decreasing acetylated p65 levels.

Screening for Psychological Distress and Risk of Cardiovascular Disease and Related Mortality: A SYSTEMATIZED REVIEW, META-ANALYSIS, AND CASE FOR PREVENTION

BACKGROUND

Psychological distress-elevated symptoms of depression, anxiety, post-traumatic stress disorder (PTSD), or psychosocial stress-has been associated with risk for cardiovascular disease (CVD). Despite increasing attention to the importance of these factors for CVD prevention, the state of this science requires updated synthesis to enable practice recommendations. Moreover, it is unknown whether psychological distress based on screeners, validated self-report instruments that efficiently identify those who may require mental health services or additional support, is associated with incident CVD.

METHODS

MEDLINE, Embase, and PsycInfo were searched for studies published 2017-2022, including adults without a past psychiatric diagnosis, who were screened at baseline for depression, anxiety, PTSD, stress, or general mental health symptoms, and followed for >6 mo to determine their risk for incident CVD (ie, atrial fibrillation, acute coronary syndrome, coronary heart disease, peripheral vascular disease, heart failure, or a composite). A meta-analysis was used to aggregate results to determine whether clinically significant levels of psychological distress were associated with CVD onset.

RESULTS

The search identified 28 investigations that represented 658 331 participants (58% women). Fifteen studies had adequate data for the primary meta-analysis, which indicated that those reporting high psychological distress showed a 28% greater risk of incident CVD compared with those with low or no distress.

CONCLUSIONS

Rapid screening for psychological distress is a helpful and efficient approach to understanding the CVD risk profile of an individual. Additional investigations are needed to improve prospective evidence concerning psychosocial stress. Conducting analyses by sex may better elucidate the benefits of psychological distress screening for men and women, respectively, and encourage more widespread adoption in CVD prevention.

The relation of common inflammatory cytokines with anxiety and depression and their values in estimating cardiovascular outcomes in coronary heart disease patients

Background

Inflammatory cytokines are associated with the occurrence and severity of psychological disorders in cerebro‐cardiovascular disease patients. This study aimed to investigate the correlation of inflammatory cytokines with anxiety and depression in coronary heart disease (CHD) patients and their values for estimating cardiovascular outcomes.

Methods

Totally, 150 CHD patients and 50 healthy subjects were enrolled. Then, tumor necrosis factor (TNF)‐α, interleukin (IL)‐1β, IL‐6, IL‐10, and IL‐17 in their serum samples were detected using ELISA assay; anxiety and depression were assessed by the HADS score. For CHD patients, major adverse cardiac events (MACE) were recorded and evaluated.

Results

CHD patients presented with increased TNF‐α (median: 50.0 vs. 37.0 pg/ml, p < 0.001), IL‐1β (median: 2.7 vs. 2.0 pg/ml, p < 0.001), IL‐6 (median: 24.7 vs. 24.3 pg/ml, p = 0.032), IL‐17A (median: 58.6 vs. 43.6 pg/ml, p < 0.001), HADS‐A score (p < 0.001), HADS‐D score (p < 0.001), anxiety rate (p < 0.001), and depression rate (p < 0.001) compared to healthy subjects. Then, TNF‐α (p = 0.003), IL‐1β (p = 0.023), and IL‐17A (p < 0.001) were related to elevated HADS‐A score. Also, TNF‐α (p = 0.014) and IL‐17A (p = 0.020) positively, while IL‐10 (p = 0.047) negatively related to the HADS‐D score in CHD patients. Interestingly, elevated TNF‐α and IL‐17A were associated with anxiety and depression occurrence in CHD patients (all p < 0.05). Inspiringly, only TNF‐α high, but not other cytokines, was related to elevated accumulating MACE (p = 0.041), while no correlation of anxiety (p = 0.173) or depression (p = 0.068) with accumulating MACE was observed.

Conclusion

TNF‐α and IL‐17A correlate with anxiety and depression, while only TNF‐α high is related to elevated accumulating MACE in CHD patients.

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.

Summary

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.

The association between type 2 diabetes and anhedonic subtype of major depression in hypertensive individuals

Given the limited data in the literature, the aim of this study was to investigate the association between type 2 diabetes and anhedonic subtype of major depression in hypertensive individuals. Demographic and polysomnographic data from 323 hypertensive individuals recruited from the database of the Erasme Hospital Sleep Laboratory were analysed. Only individuals with a diagnosis of type 2 diabetes according to the diagnostic criteria of the American Diabetes Association at admission were included in the "diabetes group". Logistic regression analyses were used to study the association between type 2 diabetes and anhedonic subtype of major depression in hypertensive individuals. The rate of type 2 diabetes was 18.9% in our sample of hypertensive individuals. After adjusting for major confounding factors, multivariate logistic regression analyses demonstrated that unlike the non-anhedonic subtype of major depression, only the anhedonic subtype of major depression was significantly associated with higher likelihood of having type 2 diabetes in hypertensive individuals. In this study, the authors demonstrated that the anhedonic subtype of major depression is significantly associated with type 2 diabetes in hypertensive individuals, which could potentially open up new perspectives for the development of therapeutic strategies complementary to conventional treatments for type 2 diabetes in this subpopulation at high risk of complications related to the co-occurrence of this metabolic disorder.

From Heartbreak to Heart Disease: A Narrative Review on Depression as an Adjunct to Cardiovascular Disease

Patients with cardiovascular disease (CVD) commonly have subclinical depression and are often delayed in their diagnosis. Literature suggests an increased association of depression and adverse cardiovascular events like myocardial infarction and heart failure. Prevalence of depression in developed countries is approximately 16.6%, and it confers higher cardiovascular mortality even after attrition bias and confounding factors are eliminated. Pharmacological and cognitive-behavioral therapy have been extensively studied, and are generally safe and effective in alleviating depressive symptoms in patients with CVD. However, their impact on cardiovascular outcomes is still unclear. Results of randomized controlled trials have shown antidepressants, especially selective serotonin reuptake inhibitors, to be safe and effective for healing a "broken heart." This review outlines the prevalence of depression in patients with CVD, the pathophysiological mechanism causing cardiovascular events with depression, and a link between depression and CVD. There is a wealth of literature explaining the precursor of CVD in depression, and like all chronic diseases, inflammation seems to be the culprit in this case as well.

Affective brain patterns as multivariate neural correlates of cardiovascular disease risk

This study tested whether brain activity patterns evoked by affective stimuli relate to individual differences in an indicator of pre-clinical atherosclerosis: carotid artery intima-media thickness (CA-IMT). Adults (aged 30-54 years) completed functional magnetic resonance imaging (fMRI) tasks that involved viewing three sets of affective stimuli. Two sets included facial expressions of emotion, and one set included neutral and unpleasant images from the International Affective Picture System (IAPS). Cross-validated, multivariate and machine learning models showed that individual differences in CA-IMT were partially predicted by brain activity patterns evoked by unpleasant IAPS images, even after accounting for age, sex and known cardiovascular disease risk factors. CA-IMT was also predicted by brain activity patterns evoked by angry and fearful faces from one of the two stimulus sets of facial expressions, but this predictive association did not persist after accounting for known cardiovascular risk factors. The reliability (internal consistency) of brain activity patterns evoked by affective stimuli may have constrained their prediction of CA-IMT. Distributed brain activity patterns could comprise affective neural correlates of pre-clinical atherosclerosis; however, the interpretation of such correlates may depend on their psychometric properties, as well as the influence of other cardiovascular risk factors and specific affective cues.

Clinical outcomes and survival analysis in patients with psycho-cardiological disease: a retrospective analysis of 132 cases

Objectives

The deleterious effects of psychological problems on coronary heart disease (CHD) are not satisfactorily explained. We explored influential factors associated with mortality in psycho-cardiological disease in a Chinese sample.

Methods

Of 7460 cardiac patients, we selected 132 patients with CHD and mental illness. Follow-up was conducted via telephone. We analyzed clinical characteristics, clinical outcomes, and survival.

Results

The clinical detection rate of psycho-cardiological disease in the overall patient population was 1.8%. Of these, 113 patients completed follow-up; 18 died owing to cardiovascular diseases during follow-up. Kaplan–Meier analysis showed dysphagia, limb function, self-care ability, percutaneous coronary intervention, low-density lipoprotein, total cholesterol, pro-brain natriuretic peptide and high-sensitivity (hs) troponin T had significant associations with cumulative survival. Cox regression analysis showed total cholesterol (hazard ratio [HR]: 2.765, 95% confidence interval [CI]: 1.001–7.641), hs troponin T (HR: 4.668, 95% CI: 1.293–16.854), and percutaneous coronary intervention (HR: 3.619, 95% CI: 1.383–9.474) were independently associated with cumulative survival.

Conclusions

The clinical detection rate of psycho-cardiological disease was far lower than expected. Normal total cholesterol and hs troponin T were associated with reduced cardiovascular disease mortality over 2 years. Percutaneous coronary intervention is a prognostic risk factor in patients with psycho-cardiological disease.

The self in context: brain systems linking mental and physical health

Increasing evidence suggests that mental health and physical health are linked by neural systems that jointly regulate somatic physiology and high-level cognition. Key systems include the ventromedial prefrontal cortex and the related default-mode network. These systems help to construct models of the 'self-in-context', compressing information across time and sensory modalities into conceptions of the underlying causes of experience. Self-in-context models endow events with personal meaning and allow predictive control over behaviour and peripheral physiology, including autonomic, neuroendocrine and immune function. They guide learning from experience and the formation of narratives about the self and one's world. Disorders of mental and physical health, especially those with high co-occurrence and convergent alterations in the functionality of the ventromedial prefrontal cortex and the default-mode network, could benefit from interventions focused on understanding and shaping mindsets and beliefs about the self, illness and treatment.

Lessons learned from an attempted randomized-controlled feasibility trial on "WIDeCAD" - An internet-based depression treatment for people living with coronary artery disease (CAD)

Despite the high prevalence of comorbid depression in people living with coronary artery disease (CAD), uptake of psychological treatment is generally low. This study was designed to investigate the feasibility of an internet-based cognitive-behavioral (iCBT) depression intervention for people with CAD and depressive symptoms.

METHODS

People with CAD and depressive symptoms (PHQ-9 ≥ 5) were randomly assigned to the eight modules comprising iCBT (N = 18), or waitlist-control (N = 16). Measures were taken at baseline (t1) and at post-treatment (eight weeks after randomization, t2). Feasibility-related outcomes were recruitment strategy, study attrition, intervention dropout, satisfaction, negative effects as well as the potential of the intervention to affect likely outcomes in a future full-scale trial (depression, anxiety, quality of life, fear of progression). Data analyses were based on intention-to-treat principles. Linear regression models were used to detect between group differences. Linear Mixed Models were used to model potential changes over time.

RESULTS

This trial was terminated prior to a-priori defined sample size has been reached given low recruitment success as well as high intervention dropout (88%) and study attrition (23%). On average, participants in the intervention group completed M = 2.78 (SD = 3.23) modules. Participants in the waitlist control group barely started one module (M = 0.82, SD = 1.81). The satisfaction with the intervention was low (M = 20.6, SD = 0.88). Participants reported no negative effects attributed to the iCBT. Differences between groups with regard to depression, anxiety, fear of progression and quality of life remained non-significant (p > 0.05).

CONCLUSION

This trial failed to recruit a sufficient number of participants. Future work should explore potential pitfalls with regards to the reach and persuasiveness of internet interventions for people living with CAD. The study gives important indications for future studies with regard to the need for new ideas to reach and treat people with CAD and depression.

A meta-analysis on heart rate variability biofeedback and depressive symptoms

Heart rate variability biofeedback (HRVB) has been used for a number of years to treat depressive symptoms, a common mental health issue, which is often comorbid with other psychopathological and medical conditions. The aim of the present meta-analysis is to test whether and to what extent HRVB is effective in reducing depressive symptoms in adult patients. We conducted a literature search on Pubmed, ProQuest, Ovid PsycInfo, and Embase up to October 2020, and identified 721 studies. Fourteen studies were included in the meta-analysis. Three meta-regressions were also performed to further test whether publication year, the questionnaire used to assess depressive symptoms, or the interval of time between T0 and T1 moderated the effect of HRVB. Overall, we analysed 14 RCTs with a total of 794 participants. The random effect analysis yielded a medium mean effect size g = 0.38 [95% CI = 0.16, 0.60; 95% PI =  - 0.19, 0.96], z = 3.44, p = 0.0006. The total heterogeneity was significant, QT = 23.49, p = 0.03, I2 = 45%, which suggested a moderate variance among the included studies. The year of publication (χ2(1) = 4.08, p = 0.04) and the questionnaire used to assess symptoms (χ2(4) = 12.65, p = 0.01) significantly moderated the effect of the interventions and reduced heterogeneity. Overall, results showed that HRVB improves depressive symptoms in several psychophysiological conditions in adult samples and should be considered as a valid technique to increase psychological well-being.

Depression After Open Heart Surgery: Influences of Optimism, Sex, and Event-Related Medical Factors

ABSTRACT

Postoperative depression is a multifaceted condition that can limit quality of life and potentially decrease the survival benefits of open heart surgery (OHS). We postulated that sex, pre-event character strengths, medical, and certain surgery indicators would predict post-event/myocardial infarction depression. To identify predictors, we collected three-wave survey data from 481 OHS patients at a large academic referral institution (age, 62+; female, 42%) and included key medical and surgical information. The final model (F[7, N = 293] = 28.15, p < 0.001, R2 = 0.408) accounted for over two fifths of the variance in post-OHS depression. Pre-event/OHS optimism mitigated post-OHS depression. Being female, older, living alone, longer surgical perfusion time, absence of left main disease greater than 50%, and pre-OHS depression were associated with the increased likelihood of post-OHS depression. Our findings suggest that teaching optimism to OHS patients might be beneficial in reducing the risk of postoperative depression and that female patients should be monitored more closely for the development of depression through an interdisciplinary approach.

The association between poor sleep quality and anxiety and depression symptoms in Chinese patients with coronary heart disease

Poor sleep quality might be a potentially modifiable predictor of prognosis in patients with coronary heart disease (CHD). Anxiety and depression symptoms are highly prevalent in these patients. Whether anxiety and depression symptoms are risk factors for poor sleep quality in Chinese patients with CHD is unclear. This study is intended to examine the prevalence of poor sleep quality in Chinese patients with CHD and its associations with anxiety and depression symptoms, and to explore whether sex, obesity and CHD type modify these associations. Three hundred and forty-eight participants were included. The Pittsburgh Sleep Quality Index (PSQI, >7 was defined as poor sleep quality) and Hospital Anxiety and Depression Scale (HADS) were used to assess sleep quality and psychological symptoms. 47.1% of the participants had poor sleep quality. Logistic regression analysis showed that poor sleep quality was independently associated with anxiety and depression symptoms adjusting for demographic and clinical factors. However, adjusted for anxiety symptoms, poor sleep quality was no longer associated with depression symptoms. Subgroup and interaction analysis showed that poor sleep quality was associated with markedly higher HADS anxiety and depression scores among patients with stable angina than those with acute coronary syndrome (ACS). These findings suggest that poor sleep quality was associated with both anxiety and depression symptoms in Chinese patients with CHD. However, in the case of concurrent anxiety and depression, anxiety was the main related factor of a high prevalence of poor sleep quality. The association between poor sleep quality and psychological symptoms was influenced by CHD type.

Psycho-Social Factors in Patients with Cardiovascular Disease Attending a Family-Centred Prevention and Rehabilitation Programme: EUROACTION Model in Spain

BACKGROUND

Coronary heart disease (CHD) persists as the leading cause of death worldwide. Cardiovascular prevention and rehabilitation (CVPR) has an interdisciplinary focus, and includes not only in physiological components, but it also addresses psycho-social factors.

METHODS

The study analysed the Spanish psycho-social data collected during the EUROACTION study. In Spain, two hospitals were randomised in the Valencia community. Coronary patients were prospectively and consecutively identified in both hospitals. The intervention hospital carried out a 16-week CVPR programme, which aimed to assess illness perceptions and establish healthy behaviours in patients and their partners.

RESULTS

Illness perceptions were significantly and inversely associated with anxiety and depression. Low levels of anxiety were associated with better self-management of total cholesterol (p = 0.004) and low-density lipoprotein-cholesterol (p = 0.004). There was concordance at one year among patients and partners who participated in the programme related to anxiety (p < 0.001), fruit consumption (p < 0.001), and vegetable consumption (p < 0.001).

CONCLUSIONS

The EUROACTION study emphasised the importance of assessing psycho-social factors in a CVPR programme and the inclusion of family as support in patients' changes in behaviour.

The Computational, Pharmacological, and Physiological Determinants of Sensory Learning under Uncertainty

The ability to represent and respond to uncertainty is fundamental to human cognition and decision-making. Noradrenaline (NA) is hypothesized to play a key role in coordinating the sensory, learning, and physiological states necessary to adapt to a changing world, but direct evidence for this is lacking in humans. Here, we tested the effects of attenuating noradrenergic neurotransmission on learning under uncertainty. We probed the effects of the β-adrenergic receptor antagonist propranolol (40 mg) using a between-subjects, double-blind, placebo-controlled design. Participants performed a probabilistic associative learning task, and we employed a hierarchical learning model to formally quantify prediction errors about cue-outcome contingencies and changes in these associations over time (volatility). Both unexpectedness and noise slowed down reaction times, but propranolol augmented the interaction between these main effects such that behavior was influenced more by prior expectations when uncertainty was high. Computationally, this was driven by a reduction in learning rates, with people slower to update their beliefs in the face of new information. Attenuating the global effects of NA also eliminated the phasic effects of prediction error and volatility on pupil size, consistent with slower belief updating. Finally, estimates of environmental volatility were predicted by baseline cardiac measures in all participants. Our results demonstrate that NA underpins behavioral and computational responses to uncertainty. These findings have important implications for understanding the impact of uncertainty on human biology and cognition.

Preoperative Optimism Related to Low Anxiety in Patients 1 Month After Open Heart Surgery

Anxiety can contribute to poor prognosis in cardiac patients. Few studies have examined the role of optimism in anxiety after open heart surgery (OHS). This study investigated the influence of preoperative optimism on post-OHS anxiety, adjusting cardiac indices used by cardiac surgeons. Data were collected before and 1 month after OHS in 481 patients (58% men; age, 62.4 ± 11.94 years). Optimism was measured using the Life Orientation Test. Anxiety was measured using the Trait Anxiety Inventory. Medical and cardiac indices were retrieved from the Society of Thoracic Surgeon's national database. Multiple regression analyses showed that greater pre-OHS optimism was associated with lower levels of post-OHS anxiety (F[6, N = 306] = 50.18, p < 0.001, R = 0.502). No other factors showed similar protection. Pre-OHS anxiety, younger age, and minority status were associated with anxiety in the critical recovery month. The findings demonstrate the potential benefit of optimism against post-OHS anxiety, which may have clinical implications for improving disease management.

Psychiatric conditions in patients presenting with Takotsubo syndrome: A systematic review and synthesis of case studies

OBJECTIVES

The purpose of this systematic review was to describe psychiatric presentations observed among Takotsubo syndrome (TS) patients, how psychiatric conditions and associated treatments impact TS events, and how psychiatric conditions are managed alongside TS medical treatment and follow-up.

METHODS

We searched MEDLINE, Cochrane Database of Systematic Reviews, Embase, PsycInfo, CINAHL, and Web of Science between 1990 and 2019 for case reports of TS with comorbid psychiatric conditions, behaviors, or substance use.

RESULTS

Of 2403 records, we included 243 records comprising 252 total cases. Common psychiatric conditions included depression (n = 98; 39%), anxiety (n = 44, 17%), alcohol use (n = 35, 14%), suicidality (n = 30, 12%), and severe mental illness (n = 25, 10%). Psychiatric conditions were frequently associated with triggering TS events (61%). Less than one-third of cases reported providing psychiatric care during hospitalization (n = 80, 32%). Only 33 cases (13%) described psychiatric functioning at follow-up. All case studies were assessed to be of low quality; patterns of reporting bias were observed.

CONCLUSIONS

Despite heterogeneous psychiatric presentations among TS patients, psychiatric treatment was rarely incorporated into the medical care or addressed at follow-up. This gap may be better attended to by integrating psychiatrists and psychologists into the multidisciplinary treatment team.

Comorbilidad afectiva en personas con hipertensión arterial: un estudio de caso-control en adultos dominicanos

En la literatura científica se encuentra un gran número de controversias y resultados dispares a la hora de explicar la relación entre la hipertensión arterial y algunas variables vinculadas a la afectividad negativa, como la depresión, la ansiedad y la ira. Teniendo esto en cuenta, en la presente investigación se planteó como objetivo principal analizar medidas de ansiedad, depresión e ira en personas adultas que padecen de hipertensión arterial (HTA). A partir de un diseño de caso-control, se contrastaron dos grupos, uno conformado por personas con HTA (n = 50) y otro de control equiparado en número de casos, edad y sexo. A nivel general, el grupo de HTA mostró mayores niveles de depresión ¾en su dimensión somática¾ y de ira-rasgo ¾en su dimensión de temperamento¾. Asimismo, las personas con HTA presentaron síntomas de irritabilidad y pérdida de energía ¾síntomas depresivo-somáticos¾, además de que tendían a enojarse con facilidad o rápidamente —sín- tomas de temperamento de ira¾. El abordaje de estos factores psicológicos comórbidos resulta de relevancia dado que en estudios precedentes ha demostrado aumentar la adherencia al tratamiento médico en pacientes que han sido diagnosticados con hipertensión o patologías similares.

Randomized controlled trial of a well-being intervention in cardiac patients

OBJECTIVE

Positive psychological well-being interventions have demonstrated promise in improving both psychological and physical health-related outcomes in patients with coronary artery disease (CAD), but evidence of the efficacy of these interventions with individuals with CAD is limited. As such, we developed an eight-week group-based intervention targeting eudaimonic aspects of psychological well-being in a randomized pilot trial. The primary aims of the trial were feasibility and acceptability, and we also explored the intervention's effectiveness on psychological outcomes.

METHOD

Participants were 40 CAD outpatients randomly assigned to the intervention (n = 20) or an attention-matched control group (n = 20). Feasibility was measured by rates of group session attendance and homework completion, and acceptability was assessed through participant ratings of intervention activities. Additional study outcomes, compared between groups, included psychological well-being, optimism, depression, and positive and negative affect.

RESULTS

The intervention met a priori criteria for feasibility and acceptability. The intervention was also associated with greater improvements in psychological well-being (β = -16.90; 95% Confidence Interval [CI] = -23.36, -10.44; p < .001, ES = 1.65), optimism (β = -8.80; 95% CI = -11.17, -6.43; t = -7.41; p < .001; ES = 2.34), and depression (β = 26.45; 95% CI = 20.97, 31.93; p < .001) immediately post-intervention, with sustained effects six weeks later.

CONCLUSIONS

These results indicate that the intervention was feasible, well-accepted, and effective in improving clinically relevant psychological outcomes in individuals with CAD. Future work should seek to replicate this work and assess general health-related and cardiac health-specific outcomes.

Optimism/hope associated with low anxiety in patients with advanced heart disease controlling for standardized cardiac confounders

Anxiety is an under-investigated comorbidity in heart disease patients. Optimism/hope is a character strength that indicates confidence or favorable expectation about the future. Previous research has consistently reported optimal health outcomes among optimists. However, many studies have lacked adjustment for medical confounders and/or used small clinical samples. To bridge this gap, we tested the hypothesis that optimism/hope was inversely related to anxiety in 400+ patients with advanced heart disease during the stressful waiting period prior to open-heart surgery. The findings supported the hypothesis after controlling for general health, illness impact, behavioral risks, and cardiac medical indices used by surgeons.
