ANXIETY IN PATIENTS UNDERGOING OPEN-HEART SURGERY: THE ROLE OF CHARACTER, STRENGTH, AND HOPE IN A STRUCTURE EQUATION MODEL

Abstract In an era of patient-centered care, more research is needed to examine the protective function of patients’ internal strengths against the damage of poor mental health. Mental health plays a significant role in cardiac health. Anxiety is a mortality risk for cardiac patients, the evidence has indicated high prevalence (13-59.5%) post cardiac events. However, anxiety hasn’t been extensively investigated as depression in cardiac patients, especially after open-heart surgery (OHS). Even less is known about protective function of Character Strength Hope in cardiac anxiety during stressful OHS, also a life-altering intervention for advanced heart conditions. This interdisciplinary study evaluated a structural equation model (SEM) on the relationship of Hope with pre- and post-OHS anxiety. Two weeks prior to the scheduled operation, research assistants conducted a face-to-face psychosocial interview with 481 patients (male, 58%; mean age=62 years, range=35-89) at the hospital, followed by a second telephone interview to assess an indicator of Hope two-days prior to surgery. Postoperative measures were assessed 36 days after OHS. Female and older patients reported higher levels of anxiety preoperatively. The SEM demonstrated adequate fit of the final solution in which pre- and post-OHS anxiety levels were related. Higher levels of pre-OHS anxiety were related to lower levels of optimism and hope right before OHS. Higher levels of optimism, indicating Hope predicted lower levels of post-OHS anxiety. Because patients with high anxiety would be disadvantaged in postoperative recovery, our finding suggests enhancing preoperative strength, Hope, might have some psychological benefits for optimal outcomes in patients undergoing OHS.

A Multicenter Cross-Sectional Study on Assessment of Depression in Cardiac Patients.

Cardiovascular diseases (CVDs) are considered the primary cause of mortality in Saudi Arabia and it is one of the major health concerns in the country. Depression can complicate, halt or even exacerbate the process of managing CVDs, making it harder to optimize the patient's condition. The main aim of this study is to assess the depression in cardiac patients. A cross-sectional observational study was conducted in 257 patients diagnosed with cardiovascular diseases. The study was conducted in two governmental hospitals in Tabuk, Saudi Arabia, from December 2021 to April 2022. Depression was assessed using the Arabic version of the CESD-R questionnaire. The mean age of the participants was 44.49 ± 12.99 years. Majority of patients were in the age group of 40-49 years (n = 92, 35.8%). More than half (53.3%) of the samples were female. The prevalence of depression among cardiac patients was 53.3%. The prevalence of depression was high among cardiac patients. It is strongly advised that routine examination and management of depression in cardiac patients be included in their regimens.

Screening for anxiety and depression in clinical practice: Translating scores from WHO-5/ASS-2/MDI-2 to HADS.

The aim of this study was to evaluate if a combination of World Health Organization-5 (WHO-5), Anxiety Symptom Scale-2 (ASS-2) and Major Depression Inventory-2 (MDI-2) can replace the Hospital Anxiety and Depression Scale (HADS) as screening tool for anxiety and depression in cardiac patients across diagnoses, and whether it is feasible to generate crosswalks (translation tables) for use in clinical practice. We used data from the Danish 'Life with a heart disease' survey, in which 10,000 patients with a hospital contact and discharge diagnosis of ischemic heart disease (IHD), heart failure (HF), heart valve disease (HVD) or atrial fibrillation (AF) in 2018 were invited. Potential participants received an electronic questionnaire including 51 questions on health, well-being, and evaluation of the health care system. Crosswalks between WHO-5/ASS-2 and HADS-A, and between WHO-5/MDI-2 and HADS-D were generated and tested using item response theory (IRT). A total of 4346 patients responded to HADS, WHO-5, ASS-2, and MDI-2. Model fit of the bi-factor IRT models illustrated appropriateness of a bi-factor structure and thus of essential uni-dimensionality (RMSEA(p value) range 0.000-0.053(0.0099-0.7529) for anxiety, and 0.033-0.061(0.0168-0.2233) for depression). A combination of WHO-5 and ASS-2 measured the same trait as HADS-A, and a combination of WHO-5 and MDI-2 measured the same trait as HADS-D. Consequently, crosswalks (translation tables) were generated. Our study shows that it is feasible to use crosswalks between HADS-A and WHO-5/ASS-2, and HADS-D and WHO-5/MDI-2 for screening cardiac patients across diagnoses for anxiety and depression in clinical practice.

Cardiac tele-rehabilitation in times of pandemic. Experience at the National Cardiovascular Institute INCOR in Lima-Peru

Cardiac Rehabilitation (CR) programs based on telehealth are an alternative in the context of a pandemic and represent an opportunity to continue in the intervention of cardiovascular diseases (CVD). The present study aims to evaluate the effect of a Cardiac Tele-Rehabilitation (CTR) program on quality of life, anxiety/depression index, exercise safety and Level Of disease awareness in patients discharged from a national referral institute in times of pandemic. A pre-experimental study in cardiac patients who entered the cardiac rehabilitation program at INCOR from August to December 2020. The study included low-risk patients who were administered a questionnaire (on cardiovascular disease, exercise safety, anxiety/depression, and quality of life) at the beginning and end of the program, which was applied through a virtual platform. Descriptive and comparative before-after analysis was used through hypothesis testing. Sixty-four patients were included (71.9% male). The mean age was 63.6 ±11.1 years. Regarding exercise safety, an increase in the mean score was found after the application of the program (3.06 ± 0.8 to 3.18 ± 0.7, p=0.324). Concerning anxiety, the mean score was reduced from 8.61 to 4.75, while for depression, the reduction was from 7.27 to 2.92. Regarding the quality-of-life score, the global component improved from 111.48 to 127.92. The CTR program implemented through a virtual platform during the COVID-19 pandemic enhanced quality of life and decreased stress and depression in cardiac patients discharged from a national cardiovascular referral center.

Psychopathology, Personality and Depression after Acute Coronary Syndrome: A Network Analysis in an Italian Population.

Several biopsychosocial factors are associated with the onset of a Major Depressive Episode (MDE) after cardiovascular events. However, little is known of the interaction between trait- and state-like symptoms and characteristics and their role in predisposing cardiac patients to MDEs. Three hundred and four subjects were selected among patients admitted for the first time at a Coronary Intensive Care Unit. Assessment comprised personality features, psychiatric symptoms and general psychological distress; the occurrences of MDEs and Major Adverse Cardiovascular Events (MACE) were recorded during a two-year follow-up period. Network analyses of state-like symptoms and trait-like features were compared between patients with and without MDEs and MACE during follow-up. Individuals with and without MDEs differed in sociodemographic characteristics and baseline depressive symptoms. Network comparison revealed significant differences in personality features, not state-like symptoms: the group with MDEs displayed greater Type D personality traits and alexithymia as well as stronger associations between alexithymia and negative affectivity (edge differences between negative affectivity and difficulty identifying feelings was 0.303, and difficulty describing feelings was 0.439). The vulnerability to depression in cardiac patients is associated with personality features but not with state-like symptoms. Personality evaluation at the first cardiac event may help identify individuals more vulnerable to development of an MDE, and they could be referred to specialist care in order to reduce their risk.

The Influence of Emotion Regulation on the Association Between Depression and Heart Rate Variability in Cardiac Patients.

Poor vagally mediated heart rate variability (vmHRV) is a mechanism linking depression to coronary heart disease (CHD). Reduced vmHRV is also considered an index of emotion dysregulation-the frequent use of maladaptive emotion regulation strategies, one of the most important being expressive suppression-which is a key component of depression. Therefore, this study aimed to investigate the moderating role of expressive suppression in the relation between depression and vmHRV in patients with CHD. The sample included 235 patients with CHD (mean [standard deviation] age = 61.6 [9.8] years; 12% women) admitted to cardiac rehabilitation after a cardiac intervention. The Beck Depression Inventory-II was administered to assess depressive symptoms. Emotion regulation strategies based on either expressive suppression or cognitive reappraisal were assessed through the Emotion Regulation Questionnaire. Resting electrocardiographic recordings were collected for 5 minutes to compute HRV indices. Expressive suppression moderated the relation between depressive symptoms and vmHRV ( b = -0.03, p = .012). Patients with lower expressive suppression scores showed no association between depressive symptoms and vmHRV ( b = -0.00, p = .94), whereas those with higher expressive suppression scores showed a significant negative association between depressive symptoms and vmHRV ( b = -0.05, p = .015). The use of expressive suppression is likely to potentiate the relation between depressive symptoms and poor vmHRV, which could increase the cardiac risk in these patients. Targeting emotion regulation skills in cardiac rehabilitation programs may be useful for reducing the impact of depression in cardiac patients.

Negative health outcomes in depressed cardiac patients are associated with both low and high psychological well-being dimensions

ABSTRACT Literature supports the positive effects of psychological well-being (P.W.B.) on health. However, most studies focused on the unitary construct of P.W.B., neglecting the different role played by distinct P.W.B. dimensions on health-related outcomes. The aim of this study was to determine whether unbalanced (i.e. low or high) levels of P.W.B. dimensions could differentially affect cardiac course after acute coronary syndrome (A.C.S.), in terms of participation in secondary prevention (S.P.) and/or survival. The sample included 136 depressed and/or demoralized A.C.S. patients referred for a S.P. program on lifestyle modification, in addition to routine cardiac visits provided by the hospital where they were admitted. Psychological assessment included validated interviews on depression and demoralization, Symptom Questionnaire and Psychological Well-Being scales. 100 patients joined the S.P. program, 36 did not. Logistic regression revealed that older age (B = 0.051; p < 0.05), higher autonomy (B = 0.070; p < 0.05) and lower personal growth (B = −0.073; p < 0.05) levels were associated with non-participation in S.P. Moreover, only among patients who did not join the program, those presenting with an impaired level of P.W.B. ‘positive relations’ dimension (i.e. below the 25th percentile) showed a worse cardiac prognosis (Log Rank: χ2 (1) = 4.654; p = 0.031). Negative health outcomes in depressed cardiac patients, such as non-participation in S.P. and worse cardiac course, are associated with both high and low levels of certain P.W.B. dimensions. Psychotherapeutic approaches geared to a balance in P.W.B. dimensions could represent promising new additions to S.P. programs.

Rumination as a key to understanding anxiety and depression in cardiac patients

It is now commonly understood that cardiac health professionals need to attend not only to patients' physical rehabilitation, but also to their emotional and mental health recovery. To ensure that mental health support is directed to those patients most at risk of poor psychological recovery post cardiac event, researchers and clinicians are continually seeking to understand the mechanisms underlying the association between anxiety, depression and heart health. One characteristic that differentiates patients with elevated risk of persistent post-event anxiety and depression is their style of cognitive processing, particularly whether they engage in negative ruminative thinking. In this article, the authors outline the impact of ruminative cognitive styles on anxiety and depression in cardiac event survivors, and highlight the importance of identifying ruminators early on in their recovery in order to appropriately direct and tailor mental health support for those who need it most.

Association between Behavioral Flexibility and Psychological Distress in Patients with Cardiovascular Disease

Objective: Being able to adapt to a changing environment has been associated with better mental and physical health. This adaptivity can be measured by behavioral flexibility assessment tools. However, the mental health consequences of behavioral flexibility have not been examined in patients with cardiovascular disease (CVD). The current study aims to examine if behavioral flexibility is associated with depression and anxiety in patients with CVD. Methods: A total of n = 387 patients with stable CVD were recruited as a part of the Do CHANGE study. At baseline, 3, and 6 months, data were collected. Depression (Patient Health Questionnaire-9) and anxiety (Generalized Anxiety Disorder Scale-7) were assessed at all time points. Results: The mean age of the sample was 61.9 ± 10.23 years, with 274 (71%) being male. An inverse association between behavioral flexibility and depression at baseline, 3, and 6 months was observed. The associations remained significant after adjusting for relevant demographic and medical variables and baseline depression. No longitudinal association between behavioral flexibility and anxiety was found in the multivariate models. Conclusions: Behavioral flexibility is associated with depression in cardiac patients. Future studies should focus on examining the pathways of this association and offering patients with low flexibility levels additional care if needed.

Impact of Rumination on Severity and Persistence of Anxiety and Depression in Cardiac Patients

Background: Anxiety and depression are common after an acute cardiac event. While many studies have investigated the predictors of anxiety and depression, few have focused on the role of rumination. The aim of this study was to identify the ruminative styles that predict anxiety and depression in the 2 years' postcardiac event. Methods: A total of 426 cardiac patients, 210 admitted for acute coronary syndrome (ACS), and 216 to undergo coronary artery bypass graft surgery were recruited from three metropolitan hospitals in Melbourne, Australia. Participants completed self-report questionnaires at the time of their event and at 12- and 24-months postevent. Anxiety and depression were assessed at all three time points, whereas ruminative styles were assessed at 24 months. Clinical information was retrieved from the participants' medical records. Bivariate and multivariate analyses were undertaken to identify the factors associated with and predictive of anxiety and depression at 24-months postevent. Results: A diagnosis of ACS, history of depression, smoking, and brooding and intrusive rumination were associated with both anxiety and depression, while female gender was associated with anxiety only. Brooding and intrusive rumination were the unique predictors of anxiety and depression, after controlling for other factors. Limitations: Generalizability of the findings is limited by the preponderance of men in the sample and by participant attrition over the study period. Conclusion: The findings indicate the importance of screening for rumination styles after a cardiac event to enhance targeting of psychological treatments for cardiac patients at risk of persistent anxiety or depression.

Metacognition in Cardiac Patients With Anxiety and Depression: Psychometric Performance of the Metacognitions Questionnaire 30 (MCQ-30).

The evaluation of effective psychological therapies for anxiety and depression in cardiac patients is a priority, and progress in this area depends on the suitability and validity of measures. Metacognitive Therapy is a treatment with established efficacy in mental health settings. It postulates that anxiety and depression are caused by dysfunctional metacognitions, such as those assessed with the Metacognitions Questionnaire 30 (MCQ-30), which impair effective regulation of repetitive negative thinking patterns. The aim of this study was to examine the psychometric properties of the MCQ-30 in a cardiac sample. A sample of 440 cardiac patients with co-morbid anxiety and/or depression symptoms completed the MCQ-30 and the Hospital Anxiety and Depression Scale. Confirmatory factor analysis (CFA) was used to test established factor structures of the MCQ-30: a correlated five-factor model and a bi-factor model. The five-factor model just failed to meet our minimum criteria for an acceptable fit on Comparative Fit Index (CFI) = 0.892 vs. criterion of ≥ 0.9; but was acceptable on the Root Mean Square Error of Approximation (RMSEA) = 0.061 vs. ≤ 0.08; whereas the bi-factor model just met those criteria (CFI = 0.913; RMSEA = 0.056). These findings suggest that the bi-factor solution may carry additional information beyond the five subscale scores alone. However, such a model needs to be evaluated further before widespread adoption could be recommended. Meantime we recommend cautious continued use of the five-factor model. Structural issues aside, all five subscales demonstrated good internal consistency (Cronbach alphas > 0.7) and similar relationships to HADS scores as in other patient populations. The MCQ-30 accounted for additional variance in anxiety and depression after controlling for age and gender.

Depression Related Pathophysiologies Relevant in Heart Disease: Insights into the Mechanism Based on Pharmacological Treatments.

Depressive symptoms are highly prevalent in patients with cardiac diseases. Co-morbid Depression in cardiac patients causes a significant reduction in health-related quality of life for the patients and inflicts an economic burden on the society. Two types of mechanisms that may explain the link between depression and cardiac diseases are the psychosocial and physiopathological mechanisms. Physiopathological mechanisms are direct biological mechanisms, which include hyperactivity of non-adrenergic and Hypothalamic Pituitary Adrenal Axis (HPA), abnormal platelet activation, endothelial dysfunction, and inflammatory process. Psychosocial factors include behavioral or lifestyle factors like smoking alcoholism and physical inactivity. Pharmacologic and therapeutic interventions are effective at reducing symptoms of depression in patients with cardiac disorders. Among pharmacological treatment, SSRIs seems to be effective for the reduction of depressive symptoms among patients with cardiac disorders because of their good efficacy and minimal cardiovascular side effects. Mechanisms of action of SSRI’s in depressive patients with cardiac disorders are associated with their ability to reduce inflammation, platelet, and endothelial dysfunction. This review focuses on the potential pathophysiological and psychosocial links between cardiac diseases and depression, the treatment options, and the importance of routine screening of depressive symptoms in cardiac settings.

Illness beliefs about depression among patients seeking depression care and patients seeking cardiac care: an exploratory analysis using a mixed method design

BackgroundTreatment of depression in cardiac patients is difficult. Patients’ illness beliefs regarding depression are associated with outcomes. The aim of the mixed-methods study was to test whether patients in routine care for depression differ from patients with depression in routine care for cardiac diseases regarding illness beliefs about depression.MethodsA consecutive sample of n = 217 patients with depressive disorder was recruited from routine care for depression (N = 148) and routine care for cardiac diseases (N = 69). Beliefs about depression were measured by the Brief-Illness Perception Questionnaire. Causal beliefs were categorized using qualitative methods. To investigate differences regarding other illness beliefs, we performed an ANCOVA controlling for sociodemographic and clinical differences by propensity score matching.ResultsPatients in routine care for cardiac diseases attributed their depression more often to physical illnesses (48% vs. 16%) and less often to their self (30% vs. 47%), problems at work (25% vs. 35%), childhood (25% vs. 30%), and negative life events (19% vs. 25%) in contrast to patients in routine care for depression. Patients in routine care for cardiac diseases reported beliefs of lower disability, burden, and treatment-control and of higher self-control in contrast to patients in routine care for depression.ConclusionsIllness beliefs especially causal beliefs differ between patients in routine care for cardiac diseases and routine care for depression. Future research should investigate effects of these illness beliefs. We recommend exploring patients’ illness beliefs about depression in routine care for cardiac diseases and routine care for depression.

Internal Medicine Residents' Attitudes Toward Simulated Depressed Cardiac Patients During an Objective Structured Clinical Examination: A Randomized Study.

Physician biases toward mental conditions such as depression have been shown to adversely affect medical outcomes. To explore the relationship between residents' explicit bias toward depressed patients and their clinical skills on a cardiac case during an objective structured clinical exam (OSCE). Prospective parallel randomized controlled study. One hundred eighty-five internal medicine residents from three residency programs in two states. During October-November 2015, residents were randomized to either a depressed or non-depressed standardized patient (SP) presenting with acute chest pain. The Medical Condition Regard Scale (MCRS) assessed residents' explicit bias toward patients with depression. Their clinical skills (history-taking, physical examination, patient counseling, patient-physician interaction (PPI), differential diagnosis, and workup plan) and facial expressions were rated during an OSCE. No significant relationships were found between resident explicit bias and clinical skill measurements. Residents who examined the depressed SP scored lower, on average, on history-taking (t [183] = -2.77, p < 0.01, Cohen's d = 0.41) and higher on PPI (t [183] = 2.24, p < 0.05, Cohen's d = 0.33) than residents examining the non-depressed SP. There were no differences, on average, between stations on physical examination, counseling, correct diagnosis, workup plan, or overall SP satisfaction. Facial recognition software demonstrated that residents with a non-depressed SP had more neutral expressions than depressed-SP residents (t [133] = -2.46, p < 0.05, Cohen's d = 0.46), and residents with a depressed SP had more disgusted expressions than non-depressed-SP residents (t [83.52] = 2.10, p < 0.05, Cohen's d = 0.28). Extrinsic bias did not predict OSCE performance in this study. Some differences were noted in the OSCE performance between the two stations. Further study is needed to examine the effects of patient mental health conditions on physician examination procedures, diagnostic behaviors, and patient outcomes.

The effect of a peer support intervention on early recovery outcomes in men recovering from coronary bypass surgery: A randomized controlled trial.

Examine the effect of a professionally-guided telephone peer support intervention on recovery outcomes including depression, perceived social support, and health services utilization after coronary artery bypass graft surgery (CABG). A randomized controlled trial was conducted with post-coronary artery bypass graft surgery men ( N=185) who were randomized before hospital discharge. The intervention arm received telephone-based peer support through weekly telephone calls from a peer volunteer over six weeks, initiated within 3-4 days of discharge. Although a significant difference was detected in pre-intervention depression scores at discharge, there were no differences between groups in changes in depression scores at six weeks ( p=0.08), 12 weeks (0.49) or over time ( p=0.51); and no significant differences in perceived social support scores over time ( p=0.94). At 12 weeks, the intervention group had significantly lower incidence of health services utilization (family physician ( p=0.02) and emergency room ( p=0.04)). Healthcare providers need to continue to investigate novel interventions to enhance social support and reduce depression in cardiac patients.

Factors associated with anxiety and depression in hospitalized patients with first episode of acute myocardial infarction.

IntroductionEvaluation of anxiety and depression in cardiac patients is an area of nursing practice that is frequently neglected. The aim of the study was to explore anxiety and depression in hospitalized patients with their first episode of acute myocardial infarction.Material and methodsThe study sample included 148 hospitalized patients who had a first episode of acute myocardial infarction. Data collection was performed by the interview method using a specially designed questionnaire which included socio-demographic, clinical and other patients’ characteristics as well as the Hospital Anxiety and Depression Scale (HADS) to assess patients’ levels of anxiety and depression.ResultsAnalysis of data showed that 52% and 38% of participants had high levels of anxiety and depression, respectively. Furthermore, anxiety levels revealed a statistically significant association with anxiolytics (p = 0.005) and antidepressant medication (p = 0.026) in hospital, the belief that they will face difficulties in relations with the social and family environment (p = 0.009 and p = 0.002, respectively) and whether they considered themselves anxious (p = 0.003). Depression was statistically significantly associated with education level (p = 0.001), profession (p = 0.007), antidepressant medication in hospital (p ≤ 0.001), patients’ relations with nursing staff (p = 0.019) and patients’ belief that they will face difficulties in relations with the social and family environment (p ≤ 0.001 and p ≤ 0.001, respectively).ConclusionsThe results showed that socio-demographic and clinical characteristics should be taken into serious consideration when exploring anxiety and depression in patients with a first episode of acute myocardial infarction in order to implement appropriate interventions.

The Techniques for Overcoming Depression Questionnaire: Mokken Scale Analysis, Reliability, and Concurrent Validity in Depressed Cardiac Patients.

The Techniques for Overcoming Depression (TOD) questionnaire assesses the frequency with which patients being treated for depression use cognitive-behavioral techniques in daily life. This study examined its latent structure, reliability and concurrent validity in depressed cardiac patients. The TOD was administered at the initial and final treatment sessions in three trials of cognitive behavior therapy (CBT) (n = 260) for depression in cardiac patients. Mokken scaling was used to determine its dimensionality. The TOD is unidimensional in depressed cardiac patients, both at the initial evaluation (H = .46) and the end of treatment (H = .47). It is sensitive to change and the total score correlates with therapist ratings of the patient's socialization to CBT (r=.40, p<.05), homework adherence (r=0.36, p<0.05), and use of cognitive-behavioral techniques (r=.51, p<.01). TOD scores were associated with post-treatment depression scores in two of the trials (p<.01 in both analyses). The TOD is a unidimensional, reliable, valid, and clinically informative measure of self-reported use of cognitive-behavioral techniques for overcoming depression in cardiac patients. Studies of the TOD in other depressed patient populations are needed.

Cognitive behavioral therapy for depression improves pain and perceived control in cardiac surgery patients.

Depression after cardiac surgery (CS) is associated with increased pain and decreased sleep quality. While cognitive behavioral therapy (CBT) aimed at depression is effective in relieving depressive symptoms after cardiac surgery, little is known about its ability to ameliorate other common postoperative problems that affect recovery and quality of life. The purpose of this study was to evaluate the effects of CBT for depression on pain severity, pain interference, sleep, and perceived control in patients recovering from CS. Depressed patients recovering from CS were randomized to receive either eight weeks of CBT or usual care. At baseline and post-intervention, patients completed questionnaires for depressive symptoms, pain, sleep, and perceived control. Group comparisons were conducted using t-tests or chi square analysis. Repeated measures analysis was used to assess the effect of the intervention in changes over time. The sample (n=53) included 16.9% women and had a mean age of 67.8±9.2 years. CBT for depression increased perceived control (p<0.001) and decreased pain interference (p=0.02) and pain severity (p=0.03). Group effects remained significant (p<0.05) for perceived control and pain interference and a trend was observed for pain severity (p<0.10) after controlling for variables that differed at baseline. There were no group differences in sleep disturbance over time. A depression-focused CBT intervention yields benefits in other common postoperative problems, specifically improved perceived control and decreased pain in depressed cardiac surgery patients.
