Effect of Escitalopram vs Placebo Treatment for Depression on Long-term Cardiac Outcomes in Patients With Acute Coronary Syndrome: A Randomized Clinical Trial

Exploring the correlation between cardiovascular adverse events and antidepressant use: A retrospective pharmacovigilance analysis based on the FDA Adverse Event Reporting System database

BACKGROUND

The high comorbidity and mutually reinforcing relation between depression and cardiovascular disease have raised concerns about the cardiovascular risk of antidepressants. To gain a better understanding of this correlation, we performed a comprehensive evaluation regarding the types and degrees of cardiovascular adverse events (AEs) associated with 37 commonly prescribed antidepressants.

METHODS

AE reports from January 2004 to December 2023 were retrieved from the FDA Adverse Event Reporting System (FAERS) database. Disproportionality analysis was performed to identify antidepressant-related cardiovascular signals using the reporting odds ratio, proportional reporting ratio, and information component. Influencing factors of cardiovascular death, including age, sex, antidepressant choice, and concomitant medication, were explored. The underlying mechanisms of antidepressant-associated cardiovascular risk related to neurotransmitter transporters/receptors were further explored.

RESULTS

The use of antidepressants was associated with eight categories of Standardized MedDRA Queries of cardiovascular events. Different antidepressants exerted varying types and degrees of cardiovascular risks along with contributions to death in reports with cardiovascular AEs. Among them, monoamine oxidase inhibitors had the highest risk of developing six cardiovascular event categories: torsades de pointes (TdP)/QT prolongation, hypertension, cardiac arrhythmias, cardiomyopathy, pulmonary hypertension, and ischaemic heart disease. Age, male and the use of 24 types of antidepressants and concomitant medications were positively correlated with death in cardiovascular AEs. The highest risk associated with antidepressants was found in amoxapine (OR = 5.00 [2.13, 11.75], P < 0.001), followed by moclobemide (OR = 3.66 [1.85, 7.24], P < 0.001). Correlation analysis indicated the occurrence of antidepressant-related TdP/QT prolongation, hypertension and cardiomyopathy was associated with the binding and uptake inhibition of dopamine and norepinephrine transporters as well as their selectivity over serotonin transporters.

CONCLUSION

The retrospective analysis revealed that cardiovascular AEs were connected with antidepressant use, and the binding/uptake inhibitory potency and selectivity of neurotransmitters of antidepressants played an important role, providing a preliminary basis for further in-depth study of antidepressant-related cardiovascular toxicity. However, as an exploratory study, prospective studies are needed to validate our findings in the future.

The Impact of Changes in Depression on Cardiovascular Outcomes in Patients With Coronary Heart Disease

Background

Depression is associated with major adverse cardiovascular events (MACE). Whether longitudinal changes in depression affect MACE in patients with coronary heart disease (CHD) remains unknown.

Objectives

The authors evaluated the hypothesis that increasing or persistent depression predicts MACE in patients with CHD.

Methods

At baseline, 3,483 Emory Cardiovascular Biobank participants (median age 65.5 years, 31.6% female) completed the Patient Health Questionnaire 8 (PHQ8) for depression evaluation. At 1 year, 2,639 of these event-free participants repeated the questionnaire. Depression was defined as a PHQ8 score >9 and change in depressive symptoms ( Δ PHQ8) was year 1 score minus baseline PHQ8 scores. We categorized participants into never depression (both PHQ8 <10), new depression (baseline PHQ8 <10; 1-year PHQ8 >9), remitted depression (baseline PHQ8 >9; year 1 PHQ8 <10), and persistent depression (both PHQ8 >9) groups. Fine-Gray models with noncardiovascular death as the competing event and adjusted for demographics, CHD, and depression related factors evaluated how changes in depression affect MACE (cardiovascular death and MI).

Results

Overall, the incidence of MACE was 14%, with 8.7% of those with follow-up PHQ8 having MACE. 2.9% had persistent depression, 4.5% had new depression, 10.8% had remitted depression, and 81.8% never had depression. Increasing depressive symptoms independently predicted MACE ( Δ PHQ8 subdistribution HR: 1.06 [95% CI: 1.02-1.09], P < 0.001). Correspondingly, the incidence of MACE was higher in those with persistent (20.8%) or new depression (11.9%) than in those with remitted (9.4%) or never depression (8%) (P < 0.001). Compared to never depression, persistent depression independently predicted MACE (subdistribution HR: 2.78 [95% CI: 1.2-6.5], P = 0.017).

Conclusions

Increasing or persistent depression predicts MACE in individuals with CHD.

Autonomic reactivity to mental stress is associated with cardiovascular mortality

Aims

The mechanisms linking acute psychological stress to cardiovascular disease (CVD) mortality are incompletely understood. We studied the relationship of electrocardiographic measures of autonomic dysfunction during acute mental stress provocation and CVD death.

Methods and results

In a pooled cohort of 765 participants with stable CVD from two related studies, we collected Holter data during standardized laboratory-based mental stress testing with a speech task and followed them for events. We assessed autonomic function using low-frequency (LF) heart rate variability (HRV) in 5-min intervals before, during, and after stress induction, and specifically examined changes from rest to stress. We employed cause-specific survival models to examine its association with CVD and all-cause mortality, controlling for demographic and CVD risk factors. The mean (SD) age was 58 (10) years, 35% were women, and 44% self-identified as Black. After a median follow-up of 5.6 years, 37 (5%) died from CVD causes. A stress-induced LF HRV decrease (67% of sample), vs. increase, was associated with a hazard ratio (HR) of 3.48 (95% confidence interval-3.25, 3.73) for CVD mortality. Low rest LF HRV (bottom quartile) was also independently associated with CVD mortality, HR = 1.75 (1.58, 1.94), vs. normal rest LF HRV (upper three quartiles). The combination of stress-induced LF HRV decrease and low rest LF HRV was associated with HR = 5.73 (5.33, 6.15) vs. the normal stress/rest LF HRV reference. We found similar results with HF HRV.

Conclusion

Stress-induced LF HRV decrease and low rest LF HRV are both independently and additively associated with a higher CVD mortality risk. Additional research is needed to assess whether targeting autonomic dysfunction may improve CVD outcomes.

Mental disorders after myocardial infarction: potential mediator role for chemokines in heart-brain interaction?

Acute myocardial infarction (MI) remains one of the leading causes of mortality and morbidity in the global communities. A prevailing topic that has attracted increasing attentions over the past few decades is the so-called heart-brain interaction, in particular following a major traumatic event such as MI. Increased prevalence of depression and other mental disorders has been recognized in cardiac patients after MI, coronary catheterization, or cardiothoracic surgeries. In this review, we focus on the potential pathogenic mechanisms and pre-clinical transcriptomic evidence for identifying potential mediators of post-MI depression. We first summarize the conventional mechanistic understanding that leads to the current clinical management of post-MI depression with the use of selective serotonin reuptake inhibitors (SSRIs) and cognitive behavior and exercise therapies. We further envisage a possible role played by certain chemokines, e.g., Chemokine (C-X-C motif) ligand 12 (CXCL12) and Chemokine (C-C motif) ligand 2 (CCL22), in serving as signaling molecules to connect the MI-induced heart damage to the pro-depressive changes in brain during the post-MI period. Future in-depth investigations into this chemokine hypothesis will be instrumental in developing new chemokine-targeted therapies for better management of the cardiac patients suffering from post-MI depression.

Functioning in an Illness and Quality of Life versus the Prevalence of Depression and Anxiety Disorders in Patients with High Cardiovascular Risk

BACKGROUND

A chronic disease occurring in a person's life is a stressor, disrupting every aspect of their life.

OBJECTIVES

This study aims to assess the relationship between functioning in chronic illness and quality of life with the prevalence of symptoms of depression and anxiety in patients with high cardiovascular risk.

MATERIAL AND METHODS

This study included 200 patients (aged 18-80 years) under the care of a primary care physician, diagnosed with hypertension and/or hypercholesterolemia, and/or diabetes between 6 and 24 months before the enrollment. The presented analysis assessed the symptoms of anxiety and depression using the Hospital Anxiety and Depression Scale (HADS); and the quality of life of patients with cardiovascular disease using the Heart Quality of Life (HeartQoL) questionnaire and functioning in chronic illness using the Functioning in Chronic Illness Scale (FCIS).

RESULTS

The HADS scores amounted to 4.34 ± 3.414 points for the HADS-Anxiety subscale and 3.20 ± 2.979 points for the HADS-Depression subscale. The score indicative of functioning in chronic illness assessed with the FCIS was 98.32 ± 13.89 points. The independent predictors of HADS-anxiety were HeartQoL Emotional and FCIS Global, while HeartQoL Global and FCIS Global were the independent predictors for HADS-depression. Better functioning in chronic illness (FCIS Global) was associated with less frequent symptoms of anxiety and depression based on the HADS: HADS-Anxiety (R Spearmann = -0.3969; p < 0.0001) and HADS-Depression (R Spearmann = -0.5884; p < 0.0001). Higher HeartQoL scores, both globally, as well as in emotional and physical dimensions, were associated with a lower severity of anxiety and depression assessed with the HADS: HADS-Anxiety (R Spearmann = -0.2909; p = 0.0001) and HADS-Depression (R Spearmann = -0.2583; p = 0.0002).

CONCLUSIONS

The quality of life and functioning in chronic illness are connected with symptoms of depression and anxiety. When assessing the severity of the depression symptoms in relation to the individual aspects of functioning in chronic illness, the areas requiring supportive-educational intervention can be identified. The assessment of both functioning in a chronic disease and the severity of the depression symptoms should be included in a standard nursing diagnosis and further supportive and educational intervention.

Depression screening in patients with coronary heart disease : A narrative review of the current evidence

In view of the large and sometimes conflicting body of research, this narrative review summarizes the current evidence on depression screening in patients with coronary heart disease. Depression is a risk factor for development and progression of coronary heart disease. Consequently, many international cardiac guidelines recommend screening for depression in patients with coronary heart disease. However, the efficacy and implementation of these guidelines are debated due to the lack of empirical evidence supporting the benefits of routine depression screening. Studies conducted in cardiac routine care support this assumption: Patients with positive depression screens do not receive adequate follow-up care, which highlights gaps in the detection-to-treatment pathway. Barriers to effective screening and treatment include system-level factors, such as insufficient integration of mental health resources in cardiology, and patient-related factors like stigma and low acceptance of mental health treatment. Innovative interventions that address these barriers and involve patients as active partners in depression care should be developed through a theory-driven, transparent, multistage process involving key stakeholders such as patients, nurses, and cardiologists. A sound methodological evaluation of such multilevel interventions could answer the question of whether early detection of depression in patients with coronary heart disease would lead to health benefits.

The Impact of Anxiety and Depression Symptoms on Cardiovascular Risk Factor Control in Patients Without a History of Atherosclerotic Cardiovascular Disease

Background

Anxiety and depression by affecting lifestyle interfere with preventive actions aimed at eliminating or reducing modifiable risk factors for cardiovascular diseases (CVD).

Purpose

The objective of the study was to assess the impact of anxiety and depression on the achievement of therapeutic goals regarding CVD risk factors in patients without a history of atherosclerotic CVD.

Patients and Methods

The study included 200 patients (median age 52.0 [IQR 43.0-60.5] years). Control of the basic risk factors was assessed: blood pressure, BMI, waist circumference, physical activity, smoking status, LDL cholesterol, triglycerides, and blood glucose. The data analysis included a comparison of the number of controlled risk factors and the percentage of subjects who achieved the therapeutic goal for each of the cardiovascular risk factors. The risk of CVD was assessed with SCORE2 and SCORE2-OP. Anxiety and depression were assessed using the Hospital Anxiety and Depression Scale (HADS). On both subscales (HADS Anxiety and HADS Depression), subjects could achieve normal, borderline, and abnormal scores.

Results

The median number of controlled CVD risk factors was 4.0 (IQR 3.0-5.0), and the median CVD risk assessed with SCORE2 and SCORE2-OP was 3.0% (IQR 1.5-7.0%). Median scores for HADS Anxiety were 3.0 (IQR 2.0-6.0) and for HADS Depression 3.0 (1.0-5.0). Patients with symptoms of anxiety and depression had significantly fewer controlled risk factors (HADS Anxiety p=0.0014; HADS Depression p=0.0304). Among subjects with anxiety and depression, there was a significantly lower percentage of those with a normal waist circumference (HADS Anxiety p=0.0464; HADS Depression p=0.0200) and regular physical activity (HADS Anxiety p=0.0431; HADS Depression p=0.0055). Among subjects with anxiety, there was a significantly lower percentage of those with a normal BMI (p=0.0218) and normal triglyceride concentrations (p=0.0278).

Conclusion

The presence of anxiety and depression may affect the control of CVD risk factors in individuals without a history of atherosclerotic CVD. Assessment of anxiety and depression symptoms should be part of a comprehensive examination of patients with high CVD risk.

The effect of escitalopram in treating mild to moderate depressive disorder and improving the quality of life in patients undergoing coronary artery bypass grafting - a double-blind randomized clinical trial

Introduction

Chronic depression and anxiety can be a risk factor for coronary aArtery bypass grafting (CABG) and is an emerging factor after coronary artery disease when the patient is admitted to the hospital and after surgery. We aimed to assess the effect of Escitalopram in treating mild to moderate depressive disorder and improving the quality of life in patients undergoing CABG.

Methods

In this randomized clinical trial, 50 patients undergoing CABG referred to Tehran Heart Hospital from January 2021 to May 2021 and were suffering from mild to moderate depression were randomly assigned to one of the two groups of Escitalopram or placebo. The level of depression was assessed based on Beck's depression inventory and the quality-of-life status and its domains were assessed based on the SF-36 questionnaire in 2 groups. Measurements were obtained at baseline and at four and eight weeks after treatment. Chi-square, Fisher's exact, paired, and Wilcoxon tests or ANOVA were used as appropriate.

Results

There was no significant difference between the level of depression between the two study groups at baseline (P=0.312). There was no significant difference between the quality of life and its domains in the two study groups at baseline (P=0.607). However, the most important effect of Escitalopram was reducing depression scores in the intervention group at weeks 4 and 8 after treatment compared to the placebo group (P<0.001). The quality of life and its domains were significantly higher in the Escitalopram group eight weeks after treatment (P=0.004). The amount of drug side effects at 2 and 4 weeks after treatment had no significant difference between the groups (P>0.05).

Conclusion

Escitalopram was effective in treating mild to moderate depressive disorder and improving quality of life in patients undergoing CABG.

The Effects of mHealth Interventions on Quality of Life, Anxiety, and Depression in Patients With Coronary Heart Disease: Meta-Analysis of Randomized Controlled Trials

BACKGROUND

Coronary heart disease (CHD) is the leading cause of death globally. In addition, 20% to 40% of the patients with CHD have comorbid mental health issues such as anxiety or depression, affecting the prognosis and quality of life (QoL). Mobile health (mHealth) interventions have been developed and are widely used; however, the evidence for the effects of mHealth interventions on QoL, anxiety, and depression in patients with CHD is currently ambiguous.

OBJECTIVE

In this study, we aimed to assess the effects of mHealth interventions on QoL, anxiety, and depression in patients with CHD.

METHODS

We searched the Cochrane Library, PubMed, Embase, CINAHL, Web of Science, China National Knowledge Infrastructure, and Wanfang databases from inception to August 12, 2023. Eligible studies were randomized controlled trials that involved patients with CHD who received mHealth interventions and that reported on QoL, anxiety, or depression outcomes. We used the Cochrane risk-of-bias tool for randomized trials to evaluate the risk of bias in the studies, ensuring a rigorous and methodologically sound analysis. Review Manager (desktop version 5.4; The Cochrane Collaboration) and Stata MP (version 17.0; StataCorp LLC) were used to conduct the meta-analysis. The effect size was calculated using the standardized mean difference (SMD) and its 95% CI.

RESULTS

The meta-analysis included 23 studies (5406 participants in total) and showed that mHealth interventions significantly improved QoL in patients with CHD (SMD 0.49, 95% CI 0.25-0.72; Z=4.07; P<.001) as well as relieved their anxiety (SMD -0.46, 95% CI -0.83 to -0.08; Z=2.38; P=.02) and depression (SMD -0.34, 95% CI -0.56 to -0.12; Z=3.00; P=.003) compared to usual care. The subgroup analyses indicated a significant effect favoring the mHealth intervention on reducing anxiety and depressive symptoms compared to usual care, especially when (1) the intervention duration was ≥6 months (P=.04 and P=.001), (2) the mHealth intervention was a simple one (only 1 mHealth intervention was used) (P=.01 and P<.001), (3) it was implemented during the COVID-19 pandemic (P=.04 and P=.01), (4) it was implemented in low- or middle-income countries (P=.01 and P=.02), (5) the intervention focused on mental health (P=.01 and P=.007), and (6) adherence rates were high (≥90%; P=.03 and P=.002). In addition, comparing mHealth interventions to usual care, there was an improvement in QoL when (1) the mHealth intervention was a simple one (P<.001), (2) it was implemented in low- or middle-income countries (P<.001), and (3) the intervention focused on mental health (P<.001).

CONCLUSIONS

On the basis of the existing evidence, mHealth interventions might be effective in improving QoL and reducing anxiety and depression in patients with CHD. However, large sample, high-quality, and rigorously designed randomized controlled trials are needed to provide further evidence.

Systemic Inflammation in Asthma: What Are the Risks and Impacts Outside the Airway?

Airway inflammation in asthma has been well recognized for several decades, with general agreement on its role in asthma pathogenesis, symptoms, propensity toward exacerbation, and decline in lung function. This has led to universal recommendation in asthma management guidelines to incorporate the use of inhaled corticosteroid as an anti-inflammatory therapy for all patients with persistent asthma symptoms. However, there has been limited attention paid to the presence and potential impact of systemic inflammation in asthma. Accumulating evidence from epidemiological observations and cohort studies points to a host of downstream organ dysfunction in asthma especially among patients with longstanding or more severe disease, frequent exacerbations, and underlying risk factors for organ dysfunction. Most studies to date have focused on cognitive impairment, depression/anxiety, metabolic syndrome, and cardiovascular abnormalities. In this review, we summarize some of the evidence demonstrating these abnormalities and highlight the proposed mechanisms and potential benefits of treatment in limiting these extrapulmonary abnormalities in patients with asthma. The goal of this commentary is to raise awareness of the importance of recognizing potential extrapulmonary conditions associated with systemic inflammation of asthma. This area of treatment of patients with asthma is a large unmet need.

Depression and coronary heart disease: mechanisms, interventions, and treatments

Coronary heart disease (CHD), a cardiovascular condition that poses a significant threat to human health and life, has imposed a substantial economic burden on the world. However, in contrast to conventional risk factors, depression emerges as a novel and independent risk factor for CHD. This condition impacts the onset and progression of CHD and elevates the risk of adverse cardiovascular prognostic events in those already affected by CHD. As a result, depression has garnered increasing global attention. Despite this growing awareness, the specific mechanisms through which depression contributes to the development of CHD remain unclear. Existing research suggests that depression primarily influences the inflammatory response, Hypothalamic-pituitary-adrenocortical axis (HPA) and Autonomic Nervous System (ANS) dysfunction, platelet activation, endothelial dysfunction, lipid metabolism disorders, and genetics, all of which play pivotal roles in CHD development. Furthermore, the effectiveness and safety of antidepressant treatment in CHD patients with comorbid depression and its potential impact on the prognosis of CHD patients have become subjects of controversy. Further investigation is warranted to address these unresolved questions.

The Role of Palliative Care in Cardiovascular Disease

The American Heart Association has recommended that palliative care be integrated into the care of all patients with advanced cardiac illnesses. Notwithstanding, the number of patients receiving specialist palliative intervention worldwide remains extremely small. This review examines the nature of palliative care and what is known about its delivery to patients with cardiac illness. Most of the published literature on the subject concern advanced heart failure; however, some data also exist regarding patients with heart transplantation, pulmonary hypertension, valvular disease, congenital heart disease, indwelling devices, mechanical circulatory support, and advanced coronary disease. In addition, outcome data, certification requirements, workforce challenges, barriers to implementation, and a potential caveat about palliative care will also be examined. Further work is required regarding appropriate means of implementation, quality control, and timing of intervention.

Needs and Preferences for Remote-Delivered Mindfulness-Based Cognitive Therapy in Patients After Acute Coronary Syndrome: A Qualitative Study

Background

Following acute coronary syndrome (ACS), up to 40% of patients report elevated depressive symptoms which is associated with a two-fold increase in mortality risk due to behavioral and biological mechanisms. Mindfulness-Based Cognitive Therapy (MBCT) delivered via synchronous group videoconferencing could help reduce depressive symptoms.

Objective

To guide MBCT adaptation for ACS patients for a future clinical trial, this qualitative study aimed to explore ACS patients' (1) symptoms after ACS, (2) needs for behavioral health treatment, (3) perspectives on mindfulness intervention and group videoconference delivery, and (4) willingness to self-collect dried blood spots in a research study.

Methods

We compared ACS patients with and without depressive symptoms to highlight particularly relevant treatment topics for patients developing depression following ACS experience. From 2/2019-11/2019, we conducted semi-structured individual telephone interviews with N = 23 patients after ACS (N = 13 with and N = 10 without elevated depressive symptoms; 63.4 (SD = 8.5) years, 87% male, 96% non-Hispanic white, 7.1 (SD = 7.5) years since ACS). In qualitative content analyses, four independent coders coded each interview.

Results

Participants with depressive symptoms experienced emotional, physical, social, and health behavior problems, while those without depressive symptoms made positive health behavior changes and struggled with anxiety symptoms. Both groups were interested in a behavioral health treatment for emotional and social support. Most were willing to participate in a mindfulness group via videoconferencing; some preferred in-person, but accessibility and convenience outweighed these cons. Almost all were willing to self-collect dried blood spots and some were already familiar with this technique.

Conclusion

ACS patients, especially those with depressive symptoms, need help managing a multitude of quality of life concerns that can be targeted with an adapted MBCT approach. A videoconference-delivered MBCT approach is of interest. Suggestions for adapting MBCT to target the needs of ACS patients are discussed.

Cardiovascular adverse reactions associated with escitalopram in patients with underlying cardiovascular diseases: a systematic review and meta-analysis

Background

Despite the anticipated efficacy of escitalopram in treating depression and anxiety in individuals with preexisting cardiovascular conditions, persistent concerns regarding its adverse effects have emerged. In this systematic review, we aimed to evaluate the cardiovascular safety profile of escitalopram compared with that of placebo in patients with underlying cardiovascular disease.

Methods

We used a predefined search strategy in PubMed, Cochrane Central Register of Controlled Trials, Embase, International Clinical Trials Registry Platform, and ClinicalTrials.gov to identify studies evaluating adverse cardiovascular reactions to escitalopram in patients with underlying cardiovascular disease. Randomized controlled trials (RCTs) that provided results on cardiovascular safety outcomes were included. Two independent reviewers screened the abstracts and full texts of the individual studies. The risk of bias was assessed using version 2 of the Cochrane risk-of-bias tool for randomized trials. The certainty of evidence was assessed using the Grading of Recommendations, Assessment, Development, and Evaluation approach.

Results

The primary outcomes were the frequency of major adverse cardiovascular events (MACE), QTc prolongation, and discontinuation of study medication. We identified 5 RCTs with 773 participants who met the inclusion criteria. Escitalopram was not associated with significantly increased risk of MACE (risk ratio [RR] = 1.85; 95% confidence interval [CI] 0.80 to 4.26; I2 0%; 5 RCTs; n = 773, moderate certainty of evidence), discontinuation of study medication (RR = 1.03; 95% CI 0.84-1.26; I2 0%; 5 RCTs; n = 773, low certainty of evidence), and QTc prolongation (RR = 1.20; 95% CI 0.76-1.90; I2 0%; 4 RCTs; n = 646, low certainty of evidence).

Conclusion

Escitalopram does not significantly increase the risk of cardiovascular adverse reactions compared with placebo in patients with underlying cardiovascular disease. However, the presence of wide CIs and the limited number of included studies highlight the need for further studies with larger sample sizes to enhance the precision and reliability of these findings.Systematic review registration: International Prospective Register of Systematic Reviews [CRD42022298181].

Depression Following Acute Coronary Syndrome: A Review

Depression is common among patients with acute coronary syndrome (ACS). Although multiple studies have confirmed that depression is an independent risk factor for poor outcomes in ACS, general awareness of this issue is still limited. Ongoing research has described detailed aspects of depression in ACS, with various mechanistic hypotheses put forward to explain the complexity of this comorbidity. Several investigations have explored management strategies in this subgroup of patients, including screening for depression, antidepressant treatment, and cardiac rehabilitation. However, evidence of long-term improvement in clinical outcomes is still scarce, and a more comprehensive understanding of the underlying mechanisms that link depression with ACS is required to further improve disease management.

Selective serotonin reuptake inhibitors regulate the interrelation between 5-HT and inflammation after myocardial infarction

BACKGROUND

Acute myocardial infarction (AMI) is a main cause of death all around the world. There is a close relationship between myocardial infarction (MI) and depression. MI patients with untreated depression had higher mortality than those without depression. Therefore, this study aimed to explore the effect of escitalopram in treating a model under MI and unpredictable chronic mild stress (UCMS).

METHODS

Male C57BL/6J mice were treated with sham surgery, or MI surgery, or UCMS, or escitalopram (ES) for a consecutive two weeks. And the mice were divided into Sham group, MI group, MI + UCMS group, MI + UCMS + ES group (n = 8 in each group). After treatment, the mice went through open field test for anxiety behavior, sucrose preference test for depressive behavior. After sacrificed, the blood, heart, hippocampus, and cortex were collected.

RESULTS

The escitalopram badly increased the area of cardiac fibrosis size. The sucrose preference test demonstrated that escitalopram treatment showed significant effect in improving depressive behaviors of mice under MI + UCMS. The potential mechanism involved the interrelation between 5-HT system and inflammation. MI significantly affected the level of cardiac SERT. Both UCMS and ES significantly affected the level of cortex TNF-α. UCMS significantly affected the level of cardiac IL-33. In the hippocampus tissue, TNF-α was positively correlated with SERT, and IL-10 was positively correlated with SERT. In the cortex tissue, IL-33 was positively correlated with 5-HT4R, and sST2 was positively correlated with 5-HT.

CONCLUSIONS

Two-week escitalopram treatment might worsen myocardial infarction. But escitalopram could benefit depressive behaviors, which may be related with the interrelationship between the 5-HT system and inflammatory factors in the brain.

Clinical practice guidelines for cardiovascular disease: how is depression addressed? Protocol for a systematic review

INTRODUCTION

Depression frequently affects patients with cardiovascular disease (CVD). When these conditions co-occur, outcomes such as quality of life and life expectancy worsen. In everyday practice, this specific and prevalent disease-disease interaction complicates patient management. Clinical practice guidelines (CPGs) aim to provide the best available advice for clinical decision-making to improve patient care. This study will aim to evaluate how CPGs specifically address depression in patients with CVD, and whether they provide any operational guidance for screening and management of depression in the primary care and outpatient setting.

METHODS AND ANALYSIS

We will conduct a systematic review of CPGs on CVD management published from 2012 to 2023. A broad literature search for guidelines will be performed through electronic medical databases, grey literature search tools, and websites of national and professional medical organisations.Based on the inclusion criteria, two independent reviewers will evaluate eligible guidelines for screening and management recommendations on depression in patients with CVD. Additional points to be evaluated will be any mention of drug-drug or drug-disease interactions, other aspects of specific relevance to treating physicians, as well as general information on mental health.

Efficacy of Psycho-Cardiology therapy in patients with acute myocardial infarction complicated with mild anxiety and depression

Objective

To evaluate the efficacy of Psycho-Cardiology therapy among patients with acute myocardial infarction (AMI) complicated with mild anxiety and depression.

Methods

Two hundred and fifty-six patients with AMI who were admitted to the Cardiovascular Department of Chenzhou First People's Hospital from January 2018 to January 2020 were selected as subjects, and randomly divided into the control group (n = 128) and the Psycho-Cardiology treatment group (n = 128). Prior to the intervention, the general clinical data of the enrolled patients, such as gender, age, comorbidities (hypertension, diabetes) and smoking history, were compared, which revealed no statistical differences between the two groups (P > 0.05). The control group was given routine treatments such as reperfusion and secondary prevention of coronary heart disease, while the treatment group was given Psycho-Cardiology intervention in addition to the aforementioned treatments.

Results

No significant differences in PHQ-9 and GAD-7 scores were observed between the control and treatment groups at admission (P > 0.05). After the Psycho-Cardiology treatment, the PHQ-9 and GAD-7 scores of the treatment group decreased significantly. Based on the 1-year post-treatment comparison, the left ventricular ejection fraction was improved more significantly in the Psycho-Cardiology treatment group, showing statistical significance (P < 0.05). The treatment group exhibited statistically significantly low incidences of adverse cardiovascular events, such as recurrent angina pectoris, heart failure, malignant arrhythmia, recurrent myocardial infarction and death (P < 0.05).

Conclusions

Psycho-Cardiology therapy is remarkably efficacious in improving the anxiety, depression, cardiac function and reducing the occurrence of adverse cardiovascular events, which can better improve the long-term prognosis of patients with AMI compared to the traditional treatments.

Impact of Metabolic Activity of Vertebra and Amygdala on Stroke Recurrence: A Prospective Cohort Study

BACKGROUND

Elevated metabolic activity of amygdala is known to be related to atherosclerotic cardiovascular event by increasing inflammatory cell production from bone marrow. We tried to identify the factors of metabolic activity in the amygdala, vertebrae, liver, spleen, and internal carotid artery related to the future vascular events after stroke.

METHODS

A total of 110 patients with acute stroke were included (72±10 years of age, 39% women) and underwent whole-body ¹⁸F-fluorodeoxyglucose (FDG) positron emission tomography between August 1, 2015 and February 28, 2020. We compared the FDG uptake in the amygdala, vertebrae, liver, spleen, and internal carotid artery between patients with and without recurrent vascular event. Cox proportional hazards model was used to identify factors related to recurrent stroke and vascular event.

RESULTS

During the median follow-up period of 18 months, 22 patients experienced vascular events, including 15 stroke recurrence. Patients with recurred vascular event had a significantly higher FDG uptake in the amygdala and vertebrae than those without. The Cox proportional hazard model including diabetes, renal function, and carotid stenosis showed that a higher FDG uptake in the amygdala was independently associated with total vascular events (hazard ratio, 3.11 [95% CI, 1.11-8.70]) and higher FDG uptake in the vertebrae with stroke recurrence (hazard ratio, 4.94 [95% CI, 1.29-18.9]).

CONCLUSIONS

The increased metabolic activities of the vertebrae and amygdala are related to future vascular event among stroke survivors.

Operationalizing Depression Screening in Ambulatory Palliative Care: A Quality Improvement Project

BACKGROUND

Depression is common in the palliative care setting and impacts outcomes. Operationalized screening is unusual in palliative care.

LOCAL PROBLEM

Lack of operationalized depression screening at two ambulatory palliative care sites.

METHODS

A fellow-driven quality improvement initiative to implement operationalized depression screening using the patient health questionnaire-2 (PHQ-2). The primary measure was rate of EMR-documented depression screening. Secondary measures were clinician perspectives on the feasibility and acceptability of implementing the PHQ-2.

INTERVENTION

The intervention is a clinic-wide implementation of PHQ-2 screening supported by note templates, brief clinician training, referral resources for clinicians, and opportunities for indirect psychiatric consultation.

RESULTS

Operationalized depression screening rates increased from 2% to 38%. All clinicians felt incorporation of depression screening was useful and feasible.

CONCLUSIONS

Operationalized depression screening is feasible in ambulatory palliative care workflow, though optimization through having screening be completed prior to clinician visit might improve uptake.

Underestimated prognostic value of depression in patients with obstructive coronary artery disease

OBJECTIVE

The aim of this study was to explore the different predictive values of depression among patients with different cardiac systolic function levels.

METHODS

Four hundred eighty-three consecutive patients with obstructive coronary artery disease (CAD) were included the depressive state was assessed using the Chinese version of the Patient Health Questionnaire 9 (PHQ-9). Depression was defined as have depressive symptoms with a PHQ-9 score ≥5. The level of cardiac systolic function was classified as left ventricular ejection fraction (LVEF) ≥50 and <50%.

RESULTS

Over a median of 26.2 months, 421 patients completed the follow-up and experienced 101 major adverse cardiovascular events (MACEs), 45 non-cardiac rehospitalizations, and 17 deaths. Predictors for clinical outcomes in patients with different cardiac systolic function levels were not the same. For participants with preserved LVEF, depression was associated with increased risks for cardiovascular events and composite outcomes. However, when focusing the whole population, predictive values of depression for MACEs, non-cardiac rehospitalizations, and composite endpoints all dropped. Receiver operating characteristic (ROC) analyses further confirmed that depression was the one of the main predictors for all clinical outcomes. With the combination of other simple features, area under curve (AUC) could reach 0.64-0.67.

CONCLUSIONS

Inconsistent with the general impression, depression is found to have a closer linkage with clinical outcomes in CAD patients with preserved LVEF rather than in those with decreased LVEF. These findings appeal for more attention on CAD patients with depressive symptoms and comparatively normal LVEF. Including psychological factors may be a good attempt when constructing risk prediction models.

Psychoemotional risk factors for non-communicable diseases in outpatient practice. Guidelines for internists

Methodological guidelines "Psychoemotional risk factors in outpatient practice" were developed as a practical document for primary care physicians in order to expand and improve knowledge, as well as provide care to the adult population within the studied theme. The methodological guidelines include an information and content part for medical specialists and a practical part for patients, presented in the format of memos. The guidelines include the main sections: definition, structure and epidemiology of psychoemotional risk factors, psychoemotional risk factors in the clinics of internal diseases, screening of psychoemotional risk factors, prevention and correction of psychoemotional risk factors for noncommunicable diseases, non-drug care for patients, pharmacotherapy of psychoemotional disorders. The guidelines are intended for primary care physicians, for specialists who develop and implement educational programs for patients, as well as for therapeutic residents.

Increasing Uptake of Depression Screening and Treatment Guidelines in Cardiac Patients: A Behavioral and Implementation Science Approach to Developing a Theory-Informed, Multilevel Implementation Strategy

BACKGROUND

Depression leads to poor health outcomes in patients with coronary heart disease (CHD). Despite guidelines recommending screening and treatment of depressed patients with CHD, few patients receive optimal care. We applied behavioral and implementation science methods to (1) identify generalizable, multilevel barriers to depression screening and treatment in patients with CHD and (2) develop a theory-informed, multilevel implementation strategy for promoting guideline adoption.

METHODS

We conducted a narrative review of barriers to depression screening and treatment in patients with CHD (ie, medications, exercise, cardiac rehabilitation, or therapy) comprising data from 748 study participants. Informed by the behavior change wheel framework and Expert Recommendations for Implementing Change, we defined multilevel target behaviors, characterized determinants (capability, opportunity, motivation), and mapped barriers to feasible, acceptable, and equitable intervention functions and behavior change techniques to develop a multilevel implementation strategy, targeting health care systems/providers and patients.

RESULTS

We identified implementation barriers at the system/provider level (eg, Capability: knowledge; Opportunity: workflow integration; Motivation: ownership) and patient level (eg, Capability: knowledge; Opportunity: mobility; Motivation: symptom denial). Acceptable, feasible, and equitable intervention functions included education, persuasion, environmental restructuring, and enablement. Expert Recommendations for Implementing Change strategies included learning collaborative, audit, feedback, and educational materials. The final multicomponent strategy (iHeart DepCare) for promoting depression screening/treatment included problem-solving meetings with clinic staff (system); educational/motivational videos, electronic health record reminders/decisional support (provider); and a shared decision-making (electronic shared decision-making) tool with several functions for patients, for example, patient activation, patient treatment selection support.

CONCLUSIONS

We applied implementation and behavioral science methods to identify implementation barriers and to develop a multilevel implementation strategy for increasing uptake of depression screening and treatment in patients with CHD as a use case. The multilevel implementation strategy will be evaluated in a future hybrid II effectiveness-implementation trial.

Meta-Analysis of Antidepressant Pharmacotherapy in Patients Eligible for Cardiac Rehabilitation: ANTIDEPRESSANT AMBIVALENCE

PURPOSE

Many patients exhibit clinically significant depression upon enrollment in cardiac rehabilitation (CR). Antidepressants are a first-line treatment option for depression, but the effectiveness of antidepressants in patients with heart disease is mixed. The purpose of this meta-analysis was to evaluate the efficacy of antidepressants for depression in patients eligible for CR.

METHODS

A meta-analysis was conducted including randomized controlled trials of antidepressants from January 1990 to September 2021 that compared antidepressants with placebo. Random-effects models were used between group effect sizes (Hedges' g ).

RESULTS

A total of 13 trials with predominately White (68% ± 12; n =7) male (70% ± 11) samples averaging 61 ± 5 yr compared antidepressants (1128 participants) with placebo (1079 participants). Antidepressants reduced depressive symptoms ( g = 0.17: 95% CI, 0.08-0.27), but the effect was small. Heterogeneity among study effects was low ( I2 = 6.42) and nonsignificant ( Q = 10.75, P = .46), although patients with heart failure ( gHF = 0.05: 95% CI, -0.09 to 0.18) demonstrated smaller effects compared with patients with other cardiovascular disease conditions (g non-HF = 0.22: 95% CI, 0.11-0.32) ( QB [1] = 3.97; P < .05). No study reported safety concerns associated with antidepressants.

SUMMARY

The effect size of antidepressant pharmacotherapy in this population is small. No trials reported on the combined effects of exercise and pharmacotherapy. If the patient is not suicidal, CR staff may consider patient preference and refer patients for additional treatment as necessary.

Longer term benefits of exercise and escitalopram in the treatment of anxiety in patients with coronary heart disease: Six month follow-up of the UNWIND randomized clinical trial

BACKGROUND

Anxiety is a common comorbidity in patients with coronary heart disease (CHD) and is associated with worse prognosis. However, effective treatment for anxiety in CHD patients is uncertain. The UNWIND randomized clinical trial showed that 12-week treatment of escitalopram was better than exercise training or placebo in reducing anxiety in anxious CHD patients. The longer-term benefits of treatment for anxiety are not known.

METHODS

Patients were randomized to 12 weeks of Escitalopram (up to 20 mg), Exercise (3 times/wk), or placebo pill. At the conclusion of treatment, participants were followed for 6-months to determine the persistence of benefit on the primary anxiety endpoint assessed by the Hospital Anxiety and Depression Scale-Anxiety scale (HADS-A) and to assess the effects of treatment on major adverse cardiac events over a follow-up period of up to 6 years.

RESULTS

Of the 128 participants initially randomized, 120 (94%) were available for follow-up. Participants randomized to the Escitalopram condition exhibited lower HADS-A scores (3.9 [3.1, 4.7]) compared to those randomized to Exercise (5.5 [4.6, 6.3]) (P = .007) and Placebo (5.3 [4.1, 6.5]) (P = .053). Over a median follow-up of 3.2 years (IQR: 2.3, 4.5), there were 29 adverse events but no significant between-group differences.

CONCLUSION

In the UNWIND trial, 12 weeks of escitalopram treatment was effective in reducing anxiety. These beneficial effects were sustained for 6 months posttreatment. Although moderate or vigorous physical activity has a number of health benefits, exercise was not an effective treatment for anxiety in patients with CHD.

Severe Mental Illness and Cardiovascular Disease: JACC State-of-the-Art Review

People with severe mental illness, consisting of schizophrenia, bipolar disorder, and major depression, have a high burden of modifiable cardiovascular risk behaviors and conditions and have a cardiovascular mortality rate twice that of the general population. People with acute and chronic cardiovascular disease are at a higher risk of developing mental health symptoms and disease. There is emerging evidence for shared etiological factors between severe mental illness and cardiovascular disease that includes biological, genetic, and behavioral mechanisms. This state-of-the art review will describe the relationship between severe mental illness and cardiovascular disease, explore the factors that lead to poor cardiovascular outcomes in people with severe mental illness, propose strategies to improve the cardiovascular health of people with severe mental illness, and present areas for future research focus.

The Impact of Mental Stress on Cardiovascular Health—Part II

Endothelial dysfunction is one of the earliest manifestations of atherosclerosis, contributing to its development and progression. Mental stress induces endothelial dysfunction through increased activity of the sympathetic nervous system, release of corticotropin-releasing hormone from the hypothalamus, inhibition of nitric oxide (NO) synthesis by cortisol, and increased levels of pro-inflammatory cytokines. Mental-stress-induced increased output of the sympathetic nervous system and concomitant withdrawal of the parasympathetic inflammatory reflex results in systemic inflammation and activation of a neural–hematopoietic–arterial axis. This includes the brainstem and subcortical regions network, bone marrow activation, release of leukocytes into the circulation and their migration to the arterial wall and atherosclerotic plaques. Low-grade, sterile inflammation is involved in all steps of atherogenesis, from coronary plaque formation to destabilisation and rupture. Increased sympathetic tone may cause arterial smooth-muscle-cell proliferation, resulting in vascular hypertrophy, thus contributing to the development of hypertension. Emotional events also cause instability of cardiac repolarisation due to brain lateralised imbalance of cardiac autonomic nervous stimulation, which may lead to asymmetric repolarisation and arrhythmia. Acute emotional stress can also provoke severe catecholamine release, leading to direct myocyte injury due to calcium overload, known as myocytolysis, coronary microvascular vasoconstriction, and an increase in left ventricular afterload. These changes can trigger a heart failure syndrome mimicking acute myocardial infarction, characterised by transient left ventricular dysfunction and apical ballooning, known as stress (Takotsubo) cardiomyopathy. Women are more prone than men to develop mental-stress-induced myocardial ischemia (MSIMI), probably reflecting gender differences in brain activation patterns during mental stress. Although guidelines on CV prevention recognise psychosocial factors as risk modifiers to improve risk prediction and decision making, the evidence that their assessment and treatment will prevent CAD needs further evaluation.

Risk factors related to psychological distress among elderly patients with cardiovascular disease

AIM

Psychological distress is associated with poor prognosis in patients with cardiovascular disease (CVD). However, factors related to psychological distress in elderly patients with CVD is less understood. We aimed to investigate the rate of psychological distress in elderly patients with CVD in comparison with that of patients without CVD and to examine the clinical, socioeconomic, and lifestyle factors associated with this condition.

METHODS AND RESULTS

Data from a nationwide population-based study in Japan of patients aged ≥ 60 years were extracted, and 1:1 propensity score matching was conducted of patients with and without CVD. Psychological distress was assessed using the K6 scale, on which a score ≥ 6 was defined as psychological distress. Of the 24,388 matched patients, the rate of psychological distress was significantly higher among patients with CVD compared to those without CVD (29.8% vs. 20.5%, p < 0.0001). The multivariate analysis revealed that female sex, comorbidities except hypertension, current smoking, daily sleep duration of < 6  h versus ≥ 8  h, home renter versus owner, retired status, having a walking disability, and lower monthly household expenditure were independently associated with psychological distress. Walking disability was observed in greatest association with psychological distress (odds ratio 2.69, 95% confidence interval 2.46-2.93).

CONCLUSION

Elderly patients with CVD were more likely to have psychological distress compared to those without CVD. Multiple factors, including clinical, socioeconomic, and lifestyle variables, were associated with psychological distress. These analyses may help health care providers to identify high risk patients with psychological distress in a population of older adults with CVD.

Shuangxinfang Prevents S100A9-Induced Macrophage/Microglial Inflammation to Improve Cardiac Function and Depression-Like Behavior in Rats After Acute Myocardial Infarction

Background: Depression is a common complication of cardiovascular disease, which deteriorates cardiac function. Shuangxinfang (psycho-cardiology formula, PCF) was reported to alleviate myocardial ischemia injury and improve depression-like behavior. Interestingly, our previous proteomics study predicted that the protein S100A9 appeared as an important target, and macrophage/microglial inflammation might be involved in the process of PCF improving depression induced by acute myocardial infarction (AMI). This study aims to validate the proteomics results.

Methods: AMI rat models were established in vivo, followed by the administration of PCF or ABR-215757 (also named paquinimod, inhibiting S100A9 binding to TLR4) for 5 days. Forced swimming test (FST) and open field test (OFT) were applied to record depression-like behavior, and echocardiography was employed to evaluate cardiac function. Morphological changes of cardiomyocytes were assessed by HE staining and TUNEL staining on day 7 after cardiac surgery, as well as Masson trichrome staining on day 21. Hippocampal neurogenesis was determined by Nissl staining, while 5-hydroxytryptamine (5-HT), tryptophan/kynurenine ratio, and brain-derived neurotrophic factor (BDNF) in the hippocampus were analyzed as biochemical indicators of depression. We employed RT-qPCR, western blotting, and immunofluorescence to detect the expression of pathway-related genes and proteins. Myocardial and hippocampal expression of inflammatory factors were performed by ELISA. The activation of macrophage and microglia was assessed via immunoreaction using CD68 and Iba1, respectively. For in vitro confirmation, BV2 cells were primed with recombinant protein S100A9 and then treated with PCF serum or ferulic acid to determine alterations in microglial inflammation.

Results: Rats in the AMI group showed heart function deterioration and depression-like behavior. Coronary ligation not only brought about myocardial inflammation, cell apoptosis, and fibrosis but also reduced the neurogenesis, elevated the tryptophan/kynurenine ratio, and decreased the content of 5-HT. PCF could ameliorate the pathological and phenotypic changes in the heart and brain and inhibit the expression of the S100A9 protein, the activation of the microglial cell, and the secretion of IL-1β and TNF-α raised by AMI. ABR-215757 showed therapeutic effect and molecular biological mechanisms similar to PCF. Treatment with PCF serum or ferulic acid in vitro was proved to efficiently block the hyperactivation of BV2 cells and increment of cytokine contents induced by recombinant protein S100A9.

Conclusion: We identify S100A9 as a novel and potent regulator of inflammation in both the heart and brain. Macrophage/microglia inflammation mediated by S100A9 is considered a pivotal pathogenic in depression after AMI and a major pathway for the treatment of PCF, suggesting that PCF is a promising therapeutic candidate for psycho-cardiology disease.

Depression and ischemic heart disease

Depression is common in patients with ischemic heart disease, and depressed patients are more likely to develop atherosclerosis and experience major cardiac events compared with the general population. The underlying pathophysiological mechanisms of these two diseases are highly interwoven and include an increased release of stress hormones, dysregulation of the autonomic nervous system, alterations of pathways related to primary and secondary hemostasis, endothelial dysfunction, and higher level of residual inflammation. Furthermore, depression negatively impacts compliance with medication regimens. As such, early recognition and treatment of depression provide the opportunity to improve outcomes of patients with ischemic heart disease. In the present review, we provide a summary of the evidence on the epidemiology, pathophysiology and management of depression in patients with ischemic heart disease.

Association of patient-reported psychosocial healthcare and risk of readmissions and mortality in patients with ischemic heart disease: A population-based cohort study

OBJECTIVE

Psychosocial risk factors are common in patients with ischemic heart disease (IHD) and linked to poor prognosis. Psychosocial healthcare is recommended in international guidelines and has demonstrated positive effects, primarily on psychosocial symptoms. We examined the association between patient-reported psychosocial healthcare and hospital readmissions and mortality in patients with IHD.

METHODS

A population-based cohort study with register-based follow-up. Patient-reported psychosocial healthcare was measured by seven items in a survey sent to a random sample of patients with incident IHD in Denmark in 2014. We used multivariable Cox proportional hazards models and Poisson regression to examine the association between psychosocial healthcare and readmissions and all-cause mortality.

RESULTS

In total, 1083 (57%) patients were followed up to 4½ years. Low psychosocial support was reported by 53.4%, medium by 26.2% and high by 20.4% patients. The hazard of acute cardiac readmission for patients reporting low psychosocial healthcare was 2.08 higher than for patients reporting high psychosocial healthcare (95%CI:1.01-4.30). No association was found with time to first all-cause readmission. The acute cardiac readmission rate was 3.24 (95%CI:1.66-6.29) and 4.23 (95%CI:2.15-8.33) times higher among patients reporting low and medium psychosocial healthcare compared to high, and the all-cause readmission rate was 1.30 (95%CI:1.16-1.46) and 1.32 (95%CI:1.17-1.49) times higher. The hazard of death was 2.86 (95%CI:1.23-6.69) and 2.88 (95%CI:1.18-7.04) times higher among patients reporting low and medium psychosocial healthcare compared to high.

CONCLUSION

In patients with IHD, a high level of patient-reported psychosocial healthcare was significantly associated with reduced hospital readmissions and all-cause mortality.

Interaction effects of diabetes and brain-derived neurotrophic factor on suicidal ideation in patients with acute coronary syndrome

Acute coronary syndrome (ACS) is related to an increased risk of suicide. Although both diabetes and the brain-derived neurotrophic factor (BDNF) pathway are closely associated with ACS and suicide, the effects of these factors on suicidal behavior in ACS patients have not been assessed. We investigated the individual and interaction effects of diabetes and BDNF-related markers, namely the serum BDNF (sBDNF) level and the BDNF Val66Met polymorphism, on suicidal ideation (SI) in ACS patients. The presence of diabetes was ascertained, and sBDNF levels and the presence of the BDNF Val66Met polymorphism were measured in 969 patients within 2 weeks after an ACS episode. 711 patients were followed up at 1 year after the ACS episode. SI was assessed using the relevant items of the Montgomery–Åsberg Depression Rating Scale at baseline (acute SI) and the 1-year follow-up (chronic SI). Significant individual effects of low sBDNF levels were found on acute SI. The presence of both diabetes and a low sBDNF level or the BDNF Met/Met genotype was associated with acute SI, with multivariate logistic regression analyses revealing significant interaction effects. The highest frequency of chronic SI was seen in diabetic patients with an sBDNF level in the lowest tertile or with the BDNF Met/Met genotype, although the interaction terms were not statistically significant. Our study suggests that the combination of diabetes and BDNF-related markers, such as the sBDNF level and the BDNF Val66Met polymorphism, might provide a useful predictor of acute SI in ACS patients.

Depression interventions for individuals with coronary artery disease - Cost-effectiveness calculations from an Irish perspective

BACKGROUND

A substantial proportion of individuals with coronary artery disease experience moderate or severe acute depression that requires treatment. We assessed the cost-effectiveness of four interventions for depression in individuals with coronary artery disease.

METHODS

We assessed effectiveness of pharmacotherapy, psychotherapy, collaborative care and exercise as remission rate after 8 and 26 weeks using estimates from a recent network meta-analysis. The cost assessment included standard doses of antidepressants, contact frequency, and staff time per contact. Unit costs were calculated as health services' purchase price for pharmaceuticals and mid-point staff salaries obtained from the Irish Health Service Executive and validated by clinical staff. Incremental cost-effectiveness ratios were calculated as the incremental costs over incremental remissions compared to usual care. High- and low-cost scenarios and sensitivity analysis were performed with changed contact frequencies, and assuming individual vs. group psychotherapy or exercise.

RESULTS

After 8 weeks, the estimated incremental cost-effectiveness ratio was lowest for group exercise (€526 per remission), followed by pharmacotherapy (€589), individual psychotherapy (€3117) and collaborative care (€4964). After 26 weeks, pharmacotherapy was more cost-effective (€591) than collaborative care (€7203) and individual psychotherapy (€9387); no 26-week assessment for exercise was possible. Sensitivity analysis showed that group psychotherapy could be most cost-effective after 8 weeks (€519) and cost-effective after 26 weeks (€1565); however no group psychotherapy trials were available investigating its effectiveness.

DISCUSSION

Large variation in incremental cost-effectiveness ratios was seen. With the current assumptions, the most cost-effective depression intervention for individuals with coronary artery disease after 8 weeks was group exercise.

Heart-brain interactions in cardiac and brain diseases: why sex matters

Cardiovascular disease and brain disorders, such as depression and cognitive dysfunction, are highly prevalent conditions and are among the leading causes limiting patient's quality of life. A growing body of evidence has shown an intimate crosstalk between the heart and the brain, resulting from a complex network of several physiological and neurohumoral circuits. From a pathophysiological perspective, both organs share common risk factors, such as hypertension, diabetes, smoking or dyslipidaemia, and are similarly affected by systemic inflammation, atherosclerosis, and dysfunction of the neuroendocrine system. In addition, there is an increasing awareness that physiological interactions between the two organs play important roles in potentiating disease and that sex- and gender-related differences modify those interactions between the heart and the brain over the entire lifespan. The present review summarizes contemporary evidence of the effect of sex on heart-brain interactions and how these influence pathogenesis, clinical manifestation, and treatment responses of specific heart and brain diseases.

Brain-heart communication in health and diseases

Tight connections between the brain and heart have attracted a considerable amount of attention. This review focuses on the anatomical (extrinsic cardiac autonomic nervous system and intrinsic cardiac autonomic nervous system) and functional (neuroendocrine-heart axis and neuroimmune-heart axis) connections between the brain and heart, the linkage between central nervous system diseases and cardiovascular diseases, the harm of sympathetic hyperactivity to the heart, and current neuromodulation therapies. Depression is a comorbidity of cardiovascular diseases, and the two are causally related. This review summarizes the mechanisms and treatment of depression and cardiovascular diseases, providing theoretical evidence for basic research and clinical studies to improve treatment options.

Prognostic Value of Machine Learning in Patients with Acute Myocardial Infarction

(1) Background: Patients with acute myocardial infarction (AMI) still experience many major adverse cardiovascular events (MACEs), including myocardial infarction, heart failure, kidney failure, coronary events, cerebrovascular events, and death. This retrospective study aims to assess the prognostic value of machine learning (ML) for the prediction of MACEs. (2) Methods: Five-hundred patients diagnosed with AMI and who had undergone successful percutaneous coronary intervention were included in the study. Logistic regression (LR) analysis was used to assess the relevance of MACEs and 24 selected clinical variables. Six ML models were developed with five-fold cross-validation in the training dataset and their ability to predict MACEs was compared to LR with the testing dataset. (3) Results: The MACE rate was calculated as 30.6% after a mean follow-up of 1.42 years. Killip classification (Killip IV vs. I class, odds ratio 4.386, 95% confidence interval 1.943–9.904), drug compliance (irregular vs. regular compliance, 3.06, 1.721–5.438), age (per year, 1.025, 1.006–1.044), and creatinine (1 µmol/L, 1.007, 1.002–1.012) and cholesterol levels (1 mmol/L, 0.708, 0.556–0.903) were independent predictors of MACEs. In the training dataset, the best performing model was the random forest (RDF) model with an area under the curve of (0.749, 0.644–0.853) and accuracy of (0.734, 0.647–0.820). In the testing dataset, the RDF showed the most significant survival difference (log-rank p = 0.017) in distinguishing patients with and without MACEs. (4) Conclusions: The RDF model has been identified as superior to other models for MACE prediction in this study. ML methods can be promising for improving optimal predictor selection and clinical outcomes in patients with AMI.

2021 ACC/AHA/SCAI Guideline for Coronary Artery Revascularization: A Report of the American College of Cardiology/American Heart Association Joint Committee on Clinical Practice Guidelines

AIM

The guideline for coronary artery revascularization replaces the 2011 coronary artery bypass graft surgery and the 2011 and 2015 percutaneous coronary intervention guidelines, providing a patient-centric approach to guide clinicians in the treatment of patients with significant coronary artery disease undergoing coronary revascularization as well as the supporting documentation to encourage their use.

METHODS

A comprehensive literature search was conducted from May 2019 to September 2019, encompassing studies, reviews, and other evidence conducted on human subjects that were published in English from PubMed, EMBASE, the Cochrane Collaboration, CINHL Complete, and other relevant databases. Additional relevant studies, published through May 2021, were also considered.

STRUCTURE

Coronary artery disease remains a leading cause of morbidity and mortality globally. Coronary revascularization is an important therapeutic option when managing patients with coronary artery disease. The 2021 coronary artery revascularization guideline provides recommendations based on contemporary evidence for the treatment of these patients. The recommendations present an evidence-based approach to managing patients with coronary artery disease who are being considered for coronary revascularization, with the intent to improve quality of care and align with patients' interests.

Psychosocial management in cardiac rehabilitation: Current practices, recommendations, and opportunities

Psychosocial management is a core component of outpatient Phase-II cardiac rehabilitation (CR) and includes psychosocial assessment, providing interventions, measuring outcomes, and care coordination. Psychosocial management contributes to the effectiveness of comprehensive CR, but the implementation is not always consistent or clearly described in the literature, in part due to the availability of behavioral health specialists. Patients in CR have many psychosocial needs including anxiety, depression, substance use disorders, sleep problems, psychosocial stress, and cognitive impairment. Behavioral considerations are inherent in many other aspects of CR,such as participation in CR, health behaviors, adherence, and tobacco cessation. Evaluation, or psychosocial assessment, should identify significant issues, record related medications, and incorporate findings in the individual treatment plan. Some patients require further evaluation and treatment by a qualified behavioral health specialist. Psychosocial interventions provided to all patients include patient education, counseling, stress-management, a supportive environment, and exercise. Measuring outcomes entails repeating the psychosocial assessment when patients finish CR and documenting changes. Coordinating care requires understanding available local mental health infrastructure and procedures for making referrals, and may entail identifying additional resources. Interventions provided concurrently with CR to a subset of patients with more extensive needs are typically pharmacotherapy, psychotherapy, or addictions counseling, which are beyond the scope of practice for most CR professionals. The way psychosocial management is implemented suggests clinical and research opportunities. For example, the combined effects of antidepressants and CR on depression and anxiety are not known. A prominent clinical opportunity is to fully implement psychosocial assessment, as required by statute and the core components. This could involve referring patients for whom clinically significant psychosocial concerns are identified during the evaluation for a more thorough assessment by a behavioral health specialist using an appropriate billing model. A research priority is a contemporary description of behavioral health services available to CR programs, including how psychosocial management is implemented. As delivery of CR comes to include more alternative models (e.g., home-based), research is needed on how that affects the delivery of psychosocial management. Increased use of telehealth may broaden clinical opportunities for psychosocial management.

Longitudinal trends in the prevalence and treatment of depression among adults with cardiovascular disease: An analysis of national health and nutrition examination survey 2009-2020

OBJECTIVES

To assess the contemporary prevalence and decadal trends of depression and antidepressant use among adults with cardiovascular disease (CVD) in the United States, as well as their risk factors from 2009 to 2020.

MATERIALS AND METHODS

We used the National Health and Nutrition Examination Survey data to calculate the weighted prevalence of depression and antidepressant use. Adults aged 20 years or older with CVD were included. Depression and CVD were assessed by the Patient Health Questionnaire (PHQ-9) and self-report, respectively.

RESULTS

A total of 3,073 eligible participants with CVD aged >20 years were included. The overall prevalence of depression defined by PHQ-9 score ≥10 was 15.7% (95% CI 13.8-17.5), with a steady trend during 2009-March 2020 (p = 0.777). Female gender (aOR 1.78, 95% CI 1.20-2.64) and sleep disorder (aOR 2.62, 95% CI 1.78-3.86) were independent risk factors for depression in CVD patients, while high education level, high income, longer sleep duration, and non-current smokers were considered protective factors. The weighted prevalence of antidepressant use among depressed patients with CVD was 38.6%, which also remained unchanged during the survey period (p = 0.699). Participants with normal sleep pattern and duration were significantly less likely to take antidepressants (p = 0.003).

CONCLUSION

The longitudinal trends in the prevalence of depression among CVD patients in the United States have been stable over the past decade, despite being significantly higher in women, and those with sleep disorders. Overall, antidepressant use was fairly low. Aggressive screening and tailored treatment are recommended for specific vulnerable subpopulations to improve their clinical outcomes.
