Cardiac disease-induced trauma and stress-related disorders.

OBJECTIVE: This review aims to present an updated overview of cardiac disease-induced trauma and stress-related disorders such as acute stress disorder (ASD), adjustment disorder (AjD), and posttraumatic stress disorder (PTSD). First, the prevalence of these disorders, their diagnostic criteria, and their differences from other trauma-related disorders are described. Special challenges in diagnosis and treatment are identified, with various screening tools being evaluated for symptom assessment. Additionally, the risk factors studied so far for the development of symptoms of cardiac-induced posttraumatic stress disorder and the bidirectional relationship between posttraumatic stress disorder and cardiovascular diseases are summarized. Various therapeutic interventions, including pharmacological approaches, are also discussed. Finally, various areas for future research are outlined. BACKGROUND: Experiencing a cardiovascular disease, particularly a life-threatening cardiac event, can potentially lead to stress-related disorders such as ASD, AjD, and cardiac disease-induced PTSD (CDI-PTSD). If left untreated, these disorders are associated with a worsening cardiac prognosis and higher mortality rates. Approaching treatment through a trauma-focused lens may be beneficial for managing CDI-PTSD and stress-related disorders. CONCLUSION: Future research should explore treatment options for both the patients and the caregivers as well as investigate the long-term effects of trauma-focused interventions on physical and mental health outcomes.

Coronary microvascular function in male physicians with burnout and job stress: an observational study.

BACKGROUND: As a professional group, physicians are at increased risk of burnout and job stress, both of which are associated with an increased risk of coronary heart disease that is at least as high as that of other professionals. This study aimed to examine the association of burnout and job stress with coronary microvascular function, a predictor of major adverse cardiovascular events. METHODS: Thirty male physicians with clinical burnout and 30 controls without burnout were included. Burnout was assessed with the Maslach Burnout Inventory and job stress with the effort-reward imbalance and overcommitment questionnaire. All participants underwent myocardial perfusion positron emission tomography to quantify endothelium-dependent (cold pressor test) and endothelium-independent (adenosine challenge) coronary microvascular function. Burnout and job stress were regressed on coronary flow reserve (primary outcome) and two additional measures of coronary microvascular function in the same model while adjusting for age and body mass index. RESULTS: Burnout and job stress were significantly and independently associated with endothelium-dependent microvascular function. Burnout was positively associated with coronary flow reserve, myocardial blood flow response, and hyperemic myocardial blood flow (r partial = 0.28 to 0.35; p-value = 0.008 to 0.035). Effort-reward ratio (r partial = - 0.32 to - 0.38; p-value = 0.004 to 0.015) and overcommitment (r partial = - 0.30 to - 0.37; p-value = 0.005 to 0.022) showed inverse associations with these measures. CONCLUSIONS: In male physicians, burnout and high job stress showed opposite associations with coronary microvascular endothelial function. Longitudinal studies are needed to show potential clinical implications and temporal relationships between work-related variables and coronary microvascular function. Future studies should include burnout and job stress for a more nuanced understanding of their potential role in cardiovascular health.

Association between global sleep quality and coronary microvascular function in male physicians with occupational burnout.

OBJECTIVE: Occupational burnout has been associated with an increased risk of coronary heart disease, although the mechanisms involved are elusive. We investigated whether poor global sleep quality is associated with impaired coronary microvascular function in male physicians, a professional group at increased risk for burnout. METHODS: Study participants were 30 male physicians with clinical burnout and 30 controls without burnout defined by the Maslach Burnout Inventory. Global sleep quality was measured with the Pittsburgh Sleep Quality Index (PSQI). Endothelium-dependent (cold pressor test) and endothelium-independent (adenosine challenge) coronary microvascular function were quantified with myocardial perfusion positron emission tomography. In multivariable analyses, the interaction between burnout and the PSQI global score was regressed on measures of coronary microvascular function, adjusting for age, body mass index, physical activity, alcohol consumption, and main effects of burnout and PSQI score. RESULTS: The prevalence of poor sleepers (PSQI score > 5) was 40% in the burnout group and 10% in the control group. Adjusting for covariates, burnout-by-global PSQI score interactions were observed for myocardial blood flow (MBF) at rest (r partial = -.30, p = .025), endothelium-dependent coronary flow reserve (r partial = -.26, p = .062), MBF response (r partial = -.30, p = .028), and hyperemic MBF (r partial = -.34, p = -.012). The global PSQI score was inversely associated with these MBF measures in the burnout group relative to the control group. No significant interactions emerged for endothelium-independent MBF. CONCLUSIONS: In male physicians with occupational burnout, poor global sleep quality was associated with reduced endothelium-dependent coronary microvascular function, suggesting a mechanism by which burnout may affect cardiovascular health.

Posttraumatic Stress Disorder as a Consequence of Acute Cardiovascular Disease.

PURPOSE OF REVIEW: To provide an update of the current evidence of cardiac disease-induced posttraumatic stress disorder (CDI-PTSD) with a focus on acute coronary events. RECENT FINDINGS: A cardiovascular disease, particularly a life-threatening cardiac event is often a highly stressful experience that can induce PTSD in patients and their caregivers, taking a chronic course if left untreated. There are several features distinguishing CDI-PTSD from "traditional" PTSD induced by external trauma, namely enduring somatic threat, inability to avoid trauma-related cues and hyperarousal with internal body sensations leading to constant fear of recurrent cardiac events. An increased risk of recurrent CVD events may be explained by pathophysiological changes, an unhealthy lifestyle and non-adherence to cardiac treatment. A trauma-focused approach might be useful to treat CDI-PTSD. Treatment options for patients and caregivers as well as long-term effects of trauma-focused interventions on physical and mental health outcomes should be future research directions.

Insomnia Symptoms and Acute Coronary Syndrome-Induced Posttraumatic Stress Symptoms: A Comprehensive Analysis of Cross-sectional and Prospective Associations.

BACKGROUND: Acute coronary syndrome (ACS) induces clinically significant posttraumatic stress symptoms (PTSS) in 12% of patients. Subjective sleep problems are a risk factor for the development of PTSS, but this is underexplored in patients with ACS. PURPOSE: To examine the association of insomnia symptoms with ACS-induced PTSS. METHODS: In this longitudinal study with 154 patients (all white, 84.4% male, mean age 58.7 years) with a verified ACS, insomnia symptoms were interviewer assessed at hospital admission and at 3 months, using the Jenkins Sleep Scale (JSS)-4. ACS-induced PTSS were assessed with the Clinician-Administered Posttraumatic Stress Disorder Scale 3 months after hospital admission. In multivariable linear models, insomnia symptoms were regressed on PTSS, adjusting for demographics, clinical variables, health behaviors, and psychological data, including cognitive depressive symptoms. RESULTS: Greater insomnia symptoms at admission (ß = .165, p = .034), greater increase in insomnia symptoms from admission to 3 months (ß = .233, p = .008), and greater insomnia symptoms at 3 months (ß = .239, p = .002) were independently associated with more severe total PTSS at 3 months. Concerning the individual PTSS clusters, both insomnia symptoms at admission (ß = .214, p = .007) and at 3 months (ß = .213, p = .012) were independently associated with reeexperiencing symptoms. Removing sleep items from PTSS scores and excluding patients on antidepressants in two sensitivity analyses did not substantially change the results. CONCLUSIONS: Insomnia symptoms could play an important role in the development and severity of ACS-induced PTSS. This relationship seems not simply explained by the fact that sleeping difficulties are inherent to the phenotype of posttraumatic stress disorder. CLINICAL TRIAL INFORMATION: NCT01781247.

Early Psychological Counseling for the Prevention of Posttraumatic Stress Induced by Acute Coronary Syndrome: The MI-SPRINT Randomized Controlled Trial.

BACKGROUND: Acute coronary syndrome (ACS)-induced posttraumatic stress disorder (PTSD) and clinically significant PTSD symptoms (PTSS) are found in 4 and 12% of patients, respectively. We hypothesized that trauma-focused counseling prevents the incidence of ACS-induced PTSS. METHODS: Within 48 h of hospital admission, 190 patients with high distress during ACS were randomized to a single-session intervention of either trauma-focused counseling or an active control intervention targeting the general role of stress in patients with heart disease. Blind interviewer-rated PTSS (primary outcome) and additional health outcomes were assessed at 3 months of follow-up. Trial results about prevalence were compared with data from previous studies on the natural incidence of ACS-induced PTSS/PTSD. RESULTS: Intention-to-treat analyses revealed no difference in interviewer-rated PTSS between trauma-focused counseling (mean, 11.33; 95% Cl, 9.23-13.43) and stress counseling (9.88; 7.36-12.40; p = 0.40), depressive symptoms (6.01, 4.98-7.03, vs. 4.71, 3.65-5.77; p = 0.08), global psychological distress (5.15, 4.07-6.23, vs. 3.80, 2.60-5.00; p = 0.11), and the risk for cardiovascular-related hospitalization/all-cause mortality (OR, 0.67; 95% CI, 0.37-1.23). Self-rated PTSS indicated less beneficial effects with trauma-focused (6.54; 4.95-8.14) versus stress counseling (3.74; 2.39-5.08; p = 0.017). The completer analysis (154 cases) confirmed these findings. The prevalence rates of interviewer-rated PTSD (0.5%, 1/190) and self-rated PTSS were in this trial much lower than in meta-analyses and observation studies from the same cardiology department. CONCLUSIONS: Benefits were not seen for trauma-focused counseling when compared with an active control intervention. Nonetheless, in distressed ACS patients, individual, single-session, early psychological counseling shows potential as a means to prevent posttraumatic responses, but trauma-focused early treatments should probably be avoided.

Association of sleep problems with neuroendocrine hormones and coagulation factors in patients with acute myocardial infarction.

BACKGROUND: Obstructive sleep apnea (OSA) and insomnia are frequent sleep problems that are associated with poor prognosis in patients with coronary heart disease. The mechanisms linking poor sleep with an increased cardiovascular risk are incompletely understood. We examined whether a high risk of OSA as well as insomnia symptoms are associated with neuroendocrine hormones and coagulation factors in patients admitted with acute myocardial infarction. METHODS: We assessed 190 patients (mean age 60 years, 83% men) in terms of OSA risk (STOP screening tool for the assessment of high vs. low OSA risk) and severity of insomnia symptoms (Jenkins Sleep Scale for the assessment of subjective sleep difficulties) within 48 h of an acute coronary intervention. Circulating concentrations of epinephrine, norepinephrine, cortisol, fibrinogen, D-dimer, and von Willebrand factor were measured the next morning. The association of OSA risk and insomnia symptoms with neuroendocrine hormones and coagulation factors was computed using multivariate models adjusting for demographic factors, health behaviors, somatic and psychiatric comorbidities, cardiac disease-related variables, and OSA risk in the model for insomnia symptoms, respectively, for insomnia symptoms in the model for OSA risk. RESULTS: High OSA risk was identified in 41% of patients and clinically relevant insomnia symptoms were reported by 27% of patients. Compared to those with low OSA risk, patients with high OSA risk had lower levels of epinephrine (p = 0.015), norepinephrine (p = 0.049) and cortisol (p = 0.001). More severe insomnia symptoms were associated with higher levels of fibrinogen (p = 0.037), driven by difficulties initiating sleep, and with lower levels of norepinephrine (p = 0.024), driven by difficulties maintaining sleep. CONCLUSIONS: In patients with acute myocardial infarction, sleep problems are associated with neuroendocrine hormones and coagulation activity. The pattern of these relationships is not uniform for patients with a high risk of OSA and those with insomnia symptoms, and whether they contribute to adverse cardiovascular outcomes needs to be established.

Are Inflammatory Cytokines Associated with Pain during Acute Myocardial Infarction?

OBJECTIVE: Pain and inflammation during acute myocardial infarction (AMI) have been associated with the development of posttraumatic stress disorder and may also impact negatively on somatic outcome. We investigated the relationship between pain during AMI and levels of circulating proinflammatory (tumor necrosis factor [TNF]-α, interleukin [IL]-6) and anti-inflammatory (IL-33 and tissue growth factor [TGF]-ß1) cytokines. METHODS: Data were collected as part of the Myocardial Infarction - Stress Prevention Intervention (MI-SPRINT) study. We included 140 patients (mean age 59.6 years, 82.1% male) with high acute psychological distress within 48 h after MI. Fasting blood samples were drawn thereafter to measure cytokine levels. Sociodemographic factors, psychological and medical data, as well as cardiometabolic markers were assessed with questionnaires and patient interviews. RESULTS: Linear regression models showed a significant positive correlation of pain with TGF-ß1 (b = 770.91, p = 0.031) and a significant inverse correlation of pain with IL-33 (b = -0.11, p = 0.015) after controlling for age, gender, body mass index, lifetime depression, acute stress disorder symptoms, and the prognostic Global Registry of Acute Coronary Events (GRACE) score. Pain was not associated with IL-6 but with the GRACE score (b = 0.01, p = 0.003). Pain showed no significant association with TNF-α. CONCLUSION: Pain during MI was associated with anti- but not proinflammatory cytokines. As IL-33 has been shown to be cardioprotective, lower IL-33 levels with more intense pain may suggest a pathway through which increased pain during MI may have an impact on the medical prognosis.

Association of Trait Resilience With Peritraumatic and Posttraumatic Stress in Patients With Myocardial Infarction.

OBJECTIVE: Acute myocardial infarction (MI) is a life-threatening condition, leading to immediate fear and distress in many patients. Approximately 18% of patients develop posttraumatic stress disorder in the aftermath of MI. Trait resilience has shown to be a protective factor for the development of posttraumatic stress disorder. However, whether this buffering effect has already an impact on peritraumatic distress and applies to patients with MI is elusive. METHODS: We investigated 98 consecutive patients with acute MI within 48 hours after having reached stable circulatory conditions and 3 months thereafter. Peritraumatic distress was assessed retrospectively with three single-item questions about pain, fear, and helplessness during MI. All patients completed the Posttraumatic Diagnostic Scale (PDS) and the Resilience Scale to self-rate posttraumatic stress and trait resilience. RESULTS: Multivariate models adjusting for sociodemographic and medical factors showed that trait resilience was not associated with peritraumatic distress, but significantly so with posttraumatic stress. Patients with greater trait resilience showed lower PDS scores (b = -0.06, p < .001). There was no significant relationship between peritraumatic distress scores and PDS scores; resilience did not emerge as a moderator of this relationship. CONCLUSIONS: The findings suggest that trait resilience does not buffer the perception of acute MI as stressful per se but may enhance better coping with the traumatic experience in the longer term, thus preventing the development of MI-associated posttraumatic stress. Trait resilience may play an important role in posttraumatic stress symptoms triggered by medical diseases such as acute MI.

Cortisol Reactivity to Acute Psychosocial Stress in Physician Burnout.

BACKGROUND: Physician burnout, characterized by chronic job-related stress leading to emotional exhaustion, depersonalization, and reduced personal accomplishment. This cross-sectional study investigates cortisol reactivity in male physicians with burnout compared to healthy controls during an acute psychosocial stress test. METHODS: Sixty male physicians (30 burnout, 30 healthy controls) participated between September 2019 and December 2021 to investigate the impact of burnout on cardiovascular health. Salivary cortisol levels were measured before and after a Trier Social Stress Test (TSST). Burnout was assessed with the Maslach Burnout Inventory-Human Services Survey (MBI-HSS). Covariates included age, BMI, and physical activity. Data were analyzed using repeated measures analysis and area under the curve analysis. RESULTS: Male physicians with burnout exhibited significantly greater cortisol reactivity during the TSST, notably post-stress to 15 min post-stress. Emotional exhaustion correlated with reduced cortisol increase from pre-stress and smaller post-stress to 15- and 45-min declines. DISCUSSION: Findings suggest heightened cortisol reactivity in male physicians with burnout, possibly reflecting initial chronic stress stages. This study highlights the necessity for long-term research on cortisol's influence on cardiovascular health and stress responses across diverse groups. CONCLUSIONS: The findings contribute to comprehending physiological responses in burnout-afflicted physicians, emphasizing cortisol reactivity's pivotal role in stress-related research and its potential health implications, particularly within the burnout context.

Cross-sectional study on the impact of adverse childhood experiences on coronary flow reserve in male physicians with and without occupational burnout.

OBJECTIVE: Physicians face documented challenges to their mental and physical well-being, particularly in the forms of occupational burnout and cardiovascular disease. This study examined the previously under-researched intersection of early life stressors, prolonged occupational stress, and cardiovascular health in physicians. METHODS: Participants were 60 practicing male physicians, 30 with clinical burnout, defined by the Maslach Burnout Inventory, and 30 non-burnout controls. They completed the Adverse Childhood Experiences (ACE) Questionnaire asking about abuse, neglect and household dysfunctions before the age of 18, and the Perceived Stress Scale to rate thoughts and feelings about stress in the past month. Endothelium-independent (adenosine challenge) coronary flow reserve (CFR) and endothelium-dependent CFR (cold pressor test) were assessed by positron emission tomography-computed tomography. The segment stenosis score was determined by coronary computed tomography angiography. RESULTS: Twenty-six (43%) participants reported at least one ACE and five (8%) reported ≥4 ACEs. A higher ACEs sum score was associated with lower endothelium-independent CFR (r partial (rp) = -0.347, p = .01) and endothelium-dependent CFR (rp = -0.278, p = .04), adjusting for age, body mass index, perceived stress and segment stenosis score. In exploratory analyses, participants with ≥4 ACEs had lower endothelium-independent CFR (rp = -0.419, p = .001) and endothelium-dependent CFR (rp = -0.278, p = .04), than those with <4 ACEs. Endothelium-dependent CFR was higher in physicians with burnout than in controls (rp = 0.277, p = .04). No significant interaction emerged between burnout and ACEs for CFR. CONCLUSION: The findings suggest an independent association between ACEs and CFR in male physicians and emphasize the nuanced relationship between early life stressors, professional stress, and cardiovascular health.

Mindfulness Is Associated with Lower Depression, Anxiety, and Post-Traumatic Stress Disorder Symptoms and Higher Quality of Life in Patients with an Implantable Cardioverter-Defibrillator-A Cross-Sectional Study.

Several studies suggested the efficacy of dispositional mindfulness and mindfulness-based interventions in reducing anxiety and depression in cardiovascular diseases. However, data on the impact of mindfulness on the psychological well-being of patients with an implantable cardioverter-defibrillator (ICD) are scarce. In this study, 422 patients with an ICD were prospectively recruited. Logistic regression was applied to determine associations between dispositional mindfulness (Freiburg Mindfulness Inventory), depression (Patient Health Questionnaire-8), anxiety (Generalized Anxiety Disorder-7 scale), and post-traumatic stress disorder (PTSD) symptoms (Post-Traumatic Stress Diagnostic Scale), adjusting for age, sex, educational status, number of ICD shocks after ICD implantation, and physical activity. The PROCESS regression path analysis modelling tool was used to identify indirect mediating effects of dispositional mindfulness on depression, anxiety, and PTSD symptoms and quality of life (QoL; EuroQol group 5-dimension questionnaire). Participants presented high baseline QoL (mean 1.06 to 1.72) and medium-high mindfulness scores (mean 40.85 points). Higher mindfulness scores were associated with lower levels of anxiety (OR 0.90, 95% CI 0.86 to 0.95, 0.001), depression (OR 0.93, 95% CI 0.88 to 0.98, p = 0.006), and PTSD symptoms (OR 0.94, 95% CI 0.89 to 0.98, p = 0.011). Furthermore, greater mindfulness partially mediated the relationship between anxiety (indirect effect 0.10, 95% CI 0.02 to 0.21), depression (indirect effect 0.08, 95% CI 0.01 to 0.17), or PTSD (indirect effect 0.04, 95% CI 0.01 to 0.17) as independent variables and the QoL as the dependent variable. This study suggests that greater dispositional mindfulness is associated with less anxiety, depression, and PTSD symptoms. Mindfulness might also increase the QoL in ICD patients by mitigating the impact of those with psychological distress.

Underutilization of effective coping styles in male physicians with burnout.

Ineffective coping is a risk factor for burnout among physicians, in whom the prevalence of burnout is high and has also increased in recent years. We examined in a cross-sectional study whether physicians with burnout show different coping styles compared with healthy controls. Male physicians (n = 60) were recruited into two groups (burnout vs. healthy). The Coping Inventory for Stressful Situations (CISS) and the Maslach Burnout Inventory (MBI) were applied. Wilcoxon rank-sum test showed group differences in two of the three coping styles, task-oriented and emotion-oriented, and also in one of the two subscales of the avoidance-oriented coping: social-diversion-oriented coping. Multiple binomial logistic regression, controlling for age, showed that lower task-oriented coping (OR = 0.38 (0.13 - 0.93), p = 0.048, d = 0.534) and lower social-diversion-oriented coping (OR = 0.33 (0.11 - 0.80), p = 0.024, d = 0.611) significantly predicted the burnout group. The findings suggest that male physicians with burnout differ from healthy controls in terms of less frequent utilization of effective coping styles. These findings could be explored for their utility in preventing burnout in future studies.

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

AIMS: Cardiac rehabilitation (CR) not only improves cardiovascular outcomes, but also health-related quality of life (HRQOL). Unfortunately, CR is still underutilized, especially among women and older patients. Aim of this study was to highlight age- and sex-specific effects of inpatient CR on HRQOL. METHODS AND RESULTS: From 2012 to 2018, 18 459 patients were prospectively assessed in six Swiss CR clinics. Of these, we retrospectively analysed a final sample of 8286 patients with a mean (standard deviation) age of 67.8 (11.3) in men and 72.2 (11.3) in women. HRQOL was measured at CR entry and discharge. In multivariable analyses, sex- and age-specific changes in HRQOL throughout CR were estimated, adjusting for baseline HRQOL and clinical characteristics. Participants of both sexes improved significantly (P < 0.001) in all domains of HRQOL during CR. Women reported significantly lower social (P < 0.001) and emotional (P < 0.001) HRQOL than men at CR entry. Female sex predicted greater improvement in social (F = 19.63, P < 0.001), emotional (F = 27.814, P < 0.001), and physical HRQOL (F = 20.473, P < 0.001). In a subgroup of n = 2632 elderly patients (>75 years), female sex predicted greater changes in emotional (F = 15.738, P < 0.001) and physical (F = 6.295, P = 0.012), but not in social HRQOL. CONCLUSION: Women report poorer HRQOL at CR entry compared with men, but in turn particularly benefit from CR in this regard. Our results indicate that sex- and age-specific needs of patients should be considered.

Association of positive psychological well-being with circulating inflammatory markers: A systematic review and meta-analysis.

Accumulating evidence shows a protective effect of positive psychological well-being (PPWB) on health outcomes. However, the underlying mechanisms remain poorly understood. One pathway relates to enhanced immune functioning (Boehm, 2021). The aim of this project was to conduct a systematic review and meta-analysis of the association between PPWB and circulating inflammatory biomarkers and determine the magnitude of this association. After examining 748 references, 29 studies were included. Results from over 94'700 participants revealed a significant association between PPWB and reduced levels of interleukin (IL)- 6 (r = -0.05; P < .001) and C-reactive protein (CRP) (r = -0.06; P < .001) with a heterogeneity of I2 = 31.5% and I2 = 84.5%, respectively. Only the association of PPWB with CRP was independent of co-variates included in the individual studies (r = -0.04; P = .027). The findings of this systematic review and meta-analysis suggest that PPWB is associated with lower levels of inflammatory biomarkers IL-6 and CRP in the circulation. Such relationships with inflammatory biomarkers may partly explain positive effects of PPWB on health.

Sympathetic nervous system responses to acute psychosocial stress in male physicians with clinical burnout.

BACKGROUND: Occupational burnout has been associated with an increased risk of cardiovascular disease, with sympathetic nervous system (SNS) dysfunction as one explanation. This study examined the effects of burnout on responses of SNS activity measures to acute psychosocial stress in male physicians, a population at risk for burnout. METHODS: Study participants were 60 male physicians, 30 with clinical burnout, assessed with the Maslach Burnout Inventory, and 30 without burnout (controls). All participants underwent the 15-min Trier Social Stress Test. Heart rate, blood pressure, salivary alpha-amylase, and plasma levels of epinephrine (EPI) and norepinephrine were assessed pre-stress, immediately post-stress, and 15 min and 45 min post-stress. RESULTS: Physicians with burnout and controls differed in EPI changes over time, controlling for age, job stress and anxiety symptoms (F (3,147) = 5.18, p = .002 for 'Time by Group' interaction; η2p = .096). Burnout was associated with a smaller increase in EPI from pre-stress to immediately post-stress (r(54) = -.40, p = .004). The emotional exhaustion dimension of burnout was a significant driver of this effect. The area under the curve with respect to increase in EPI was also smaller in the burnout group (F (1,49) = 6.06, p = .017, η2p = .110). Group differences were not significant for the other SNS activity measures. CONCLUSIONS: Burnout may be linked to dysfunction of the sympathoadrenal medullary (SAM) system, when exposed to acute psychosocial stress. In keeping with the allostatic load concept, an insufficient SAM stress response in burnout could potentially contribute to cardiovascular disease.

Physician-Specific Symptoms of Burnout Compared to a Non-Physicians Group.

Physician burnout is a systemic problem in health care due to its high prevalence and its negative impact on professional functioning and individual well-being. While unique aspects of the physician role contributing to the development burnout have been investigated recently, it is currently unclear whether burnout manifests differently in physicians compared to the non-physician working population. We conducted an individual symptom analysis of burnout symptoms comparing a large sample of physicians with a non-physician group. In this cross-sectional online study, burnout was assessed with the Maslach Burnout Inventory-General Survey. We matched physicians with non-physicians regarding their age, gender, educational level, occupational status, and total burnout level using a "nearest neighbour matching" procedure. We then conducted a series of between-groups comparisons. Data of 3846 (51.0% women) participants including 641 physicians and 3205 non-physicians were analysed. The most pronounced difference was that physicians were more satisfied with their work performance (medium effect size (r = 0.343). Our findings indicate minor yet significant differences in burnout phenomenology between physicians and non-physicians. This demonstrates unique aspects of physician burnout and implies that such differences should be considered in occupational research among physicians, particularly when developing burnout prevention programs for physicians.

Fear of COVID-19 Predicts Depression, Anxiety and Post-Traumatic Stress Disorders in Patients with Implantable Cardioverter Defibrillators and Is Mediated by Positive and Negative Affects-A Cross-Sectional Study.

The COVID-19 pandemic affected both the physical and mental health of the general population. People with cardiac diseases seem to be particularly vulnerable to the implications of the pandemic. However, studies on the mental health impact of the COVID-19 pandemic on people with implantable cardioverter defibrillator (ICDs) are lacking. Thus, we aimed to explore the level of fear of COVID-19 and the prevalence of anxiety, depression and post-traumatic stress disorder (PTSD) in ICD patients. Furthermore, we aimed to identify novel predictors for anxiety, depression and PTSD, including COVID-19-related variables, and to assess whether positive affects (PAs) and negative affects (NAs) mediate the relationship between the level of fear of COVID-19 and anxiety, depression and PTSD, respectively. The data of 363 patients with ICDS who had been prospectively included in this study between 2020 and 2023, were analyzed. Potential predictors for anxiety, depression, and PTSD were identified using logistic regression. To identify indirect mediating effects of PAs and NAs, we applied the PROCESS regression path analysis modeling tool. The prevalence of anxiety was 9.19%, of depression 10.85%, and of PTSD 12.99%. Being unemployed was the strongest predictor for anxiety (OR = 10.39) and depression (OR = 6.54). Younger age predicted anxiety (OR = 0.95) and PTSD (OR = 0.92). Receiving low social support was associated with anxiety (OR = 0.91), depression (OR = 0.88) and PTSD (OR = 0.91). Patients with a history of COVID-19 (OR = 3.58) and those who did not feel well-informed about COVID-19 (OR = 0.29) were more likely to be depressed. Higher levels of fear of COVID-19 predicted anxiety (OR = 1.10), depression (OR = 1.12) and PTSD (OR = 1.14). The relationship between fear of COVID-19 and anxiety or depression was fully mediated by PAs and NAs, while NAs partially mediated the relationship between fear of COVID-19 and PTSD. Vulnerable subgroups of ICD patients may need additional psychological and educational interventions due to fear of COVID-19, anxiety, depression and PTSD during the pandemic.

Longitudinal association between positive affect and blood lipids in patients following acute myocardial infarction.

OBJECTIVE: Unfavorable blood lipid profiles are robust risk factors in predicting atherosclerotic disease. Studies have shown that positive affect (PA) is associated with a favorable lipid profile. However, longitudinal studies regarding the course of PA and lipid profiles in myocardial infarction (MI) patients are lacking. Therefore, the aim of this study was to prospectively explore the association between PA and blood lipid levels across three inv estigations over 12 months following acute MI. METHODS: Patients following an acute MI were examined at hospital admission (n = 190), and at 3 months (n = 154) and 12 months (n = 106) thereafter. Linear mixed effect regression models were used to evaluate the relation between PA, assessed with the Global Mood Scale, and blood lipid levels. Potential confounding variables were controlled for in the analysis. RESULTS: Higher PA was significantly associated with higher high-density lipoprotein cholesterol (HDL-C) levels and a lower total cholesterol (TC)/HDL-C ratio over time, independent of demographic factors, indices of cardiac disease severity, comorbidity, medication use, health behaviors, serum cortisol and negative affect (p≤0.040). No association was found between PA and the two blood lipids low-density lipoprotein-cholesterol (LDL-C) and triglycerides (TG). CONCLUSIONS: Positive affect was independently associated with HDL-C levels and the TC/HDL-C ratio in patients up to 1 year after MI. The findings support a potential role of PA for cardiovascular health through an association with a favorable blood lipid profile.
