Prevalence of Anxiety and Depression Symptoms in Patients with Myocardial Infarction with Non-Obstructive Coronary Arteries

Myocardical Infarction with Non-Obstructive Coronary Arteries (MINOCA): pathogenesis, diagnosis and treatment

The term MINOCA (Myocardial Infarction with Non-Obstructive Coronary Arteries) refers to myocardial infarction cases where coronary arteries exhibit less than 50 % stenosis. MINOCA encompasses a diverse range of pathologies with varying etiologies. Diagnosis involves meeting acute myocardial infarction criteria and excluding other causes (myocarditis, takotsubo syndrome). Clinical features often resemble those of traditional myocardial infarction, but MINOCA patients tend to be younger and more frequently female. Etiological investigations include coronary angiography, intracoronary imaging, and vasomotor function tests. Causes include plaque rupture, coronary dissection, vasospasm, microvascular dysfunction, thromboembolism. Prognosis varies, with some subsets at higher risk. Management involves a tailored approach addressing underlying causes, with emphasis on cardioprotective therapy, risk factor modification, and lifestyle interventions. Further research is needed to refine diagnostic strategies and optimize therapeutic approaches in MINOCA patients.

Sex-specific and ethnicity-specific differences in MINOCA

Suspected myocardial infarction with non-obstructive coronary arteries (MINOCA) has received increasing attention over the past decade. Given the heterogeneity in the mechanisms underlying acute myocardial infarction in the absence of obstructive coronary arteries, the syndrome of MINOCA is considered a working diagnosis that requires further investigation after diagnostic angiography studies have been performed, including coronary magnetic resonance angiography and functional angiography. Although once considered an infrequent and low-risk form of myocardial infarction, recent data have shown that the prognosis of MINOCA is not as benign as previously assumed. However, despite increasing awareness of the condition, many questions remain regarding the diagnosis, risk stratification and treatment of MINOCA. Women seem to be more susceptible to MINOCA, but studies on the sex-specific differences of the disease are scarce. Similarly, ethnicity-specific factors might explain discrepancies in the observed prevalence or underlying pathophysiological mechanisms of MINOCA but data are also scarce. Therefore, in this Review, we provide an update on the latest evidence available on the sex-specific and ethnicity-specific differences in the clinical features, pathophysiological mechanisms, treatment and prognosis of MINOCA.

Effect of Comprehensive Psychological Intervention on Negative Emotions and Quality of Life in Patients with Acute Myocardial Infarction

Although acute myocardial infarction (AMI) currently has a high survival rate, the treatment and prognosis are still diffuse negative life events for patients, which will affect their quality of life (QOL) and psychological health. Based on an integrated physiological-psychological-social-medical model, it is necessary to design an intervention program for safeguarding the physical and mental health of AMI patients.This study aimed to explore the influence of psychological intervention on negative emotions and QOL of AMI patients using a randomized controlled trial (RCT) design.Based on convenience sampling and double-blinded group assignment, 101 patients from August 2019 to January 2020 were randomly divided into 2 groups. An intervention group received comprehensive psychological intervention, while a control group received general supportive nursing. Both groups answered questionnaires before and after the intervention, including assessments of anxiety, depression, and QOL.Before the intervention, there were no significant differences between the groups. After intervention, anxiety and depression in the intervention group (n = 48) were significantly lower (P < 0.001) and QOL was markedly improved (P < 0.05) compared to that of the control group (n = 53).Comprehensive psychological intervention contributed to ameliorate negative emotions, enhance confidence in treatment, and improve the QOL of AMI patients.

Psychosocial Factors of Women Presenting With Myocardial Infarction With or Without Obstructive Coronary Arteries

BACKGROUND

Women with myocardial infarction (MI) are more likely to have elevated stress levels and depression than men with MI.

OBJECTIVES

We investigated psychosocial factors in women with myocardial infarction with nonobstructive coronary arteries (MINOCA) and those with MI and obstructive coronary artery disease (CAD).

METHODS

Women with MI enrolled in a multicenter study and completed measures of perceived stress (Perceived Stress Scale-4) and depressive symptoms (Patient Health Questionnaire-2) at the time of MI (baseline) and 2 months later. Stress, depression, and changes over time were compared between MI subtypes.

RESULTS

We included 172 MINOCA and 314 MI-CAD patients. Women with MINOCA were younger (age 59.4 years vs 64.2 years; P < 0.001) and more diverse than those with MI-CAD. Women with MINOCA were less likely to have high stress (Perceived Stress Scale-4 ≥6) at the time of MI (51.0% vs 63.0%; P = 0.021) and at 2 months post-MI (32.5% vs 46.3%; P = 0.019) than women with MI-CAD. There was no difference in elevated depressive symptoms (Patient Health Questionnaire-2 ≥2) at the time of MI (36% vs 43%; P = 0.229) or at 2 months post-MI (39% vs 40%; P = 0.999). No differences in the rate of 2-month decline in stress and depression scores were observed between groups.

CONCLUSIONS

Stress and depression are common among women at the time of and 2 months after MI. MINOCA patients were less likely to report high stress compared with MI-CAD patients, but the frequency of elevated depressive symptoms did not differ between the 2 groups. Stress and depressive symptoms decreased in both MI-CAD and MINOCA patients over time.

Efficacy and safety of non-pharmacological therapy under the guidance of TCM theory in the treatment of anxiety in patients with myocardial infarction: A protocol for systematic review and meta-analysis

BACKGROUND

With the increasing pressures of modern life and work, combined with a growing older population, the incidence of comorbid anxiety and myocardial infarction (MI) is increasing. Anxiety increases the risk of adverse cardiovascular events in patients with MI and significantly affects their quality of life. However, there is an ongoing controversy regarding the pharmacological treatment of anxiety in patients with MI. The concomitant use of commonly prescribed selective serotonin reuptake inhibitors (SSRIs) and antiplatelet medications such as aspirin and clopidogrel may increase the risk of bleeding. Conventional exercise-based rehabilitation therapies have shown limited success in alleviating anxiety symptoms. Fortunately, non-pharmacological therapies based on traditional Chinese medicine (TCM) theory, such as acupuncture, massage, and qigong, have demonstrated promising efficacy in treating MI and comorbid anxiety. These therapies have been widely used in community and tertiary hospital settings in China to provide new treatment options for patients with anxiety and MI. However, current studies on non-pharmacological TCM-based therapies have predominantly featured small sample sizes. This study aims to comprehensively analyze and explore the effectiveness and safety of these therapies in treating anxiety in patients with MI.

METHOD

We will systematically search six English and four Chinese databases by employing a pre-defined search strategy and adhering to the unique rules and regulations of each database to identify studies that fulfilled our inclusion criteria, to qualify for inclusion, patients must be diagnosed with both MI and anxiety, and they must have undergone non-pharmacological TCM therapies, such as acupuncture, massage, or qigong, whereas the control group received standard treatments. The primary outcome measure will be alterations in anxiety scores, as assessed using anxiety scales, with secondary outcomes encompassing the evaluations of cardiopulmonary function and quality of life. We will utilize RevMan 5.3 to conduct a meta-analysis of the collected data, and subgroup analyses will be executed based on distinct types of non-pharmacological TCM therapies and outcome measures.

RESULTS

A narrative summary and quantitative analysis of the existing evidence on the treatment of anxiety patients with MI using non-pharmacological therapies guided by Traditional Chinese Medicine theory.

CONCLUSION

This systematic review will investigate whether non-pharmacological interventions guided by TCM theory are effective and safe for anxiety in patients with MI, and provide evidence-based support for their clinical application.

Role of Intracoronary Imaging in Myocardial Infarction with Non-Obstructive Coronary Disease (MINOCA): A Review

Myocardial infarction with non-obstructive coronary artery disease occurs in 6% to 15% of all presentation of myocardial infarctions. The pathophysiologic mechanisms of MINOCA include epicardial vasospasm, coronary microvascular disorder, spontaneous coronary artery dissection, and coronary thrombus/embolism. The diagnosis is challenging, supported by intracoronary imaging with intravascular ultrasound (IVUS) and optical coherent tomography (OCT), coronary physiology testing, and cardiac magnetic resonance imaging (CMR). OCT is able to identify atherosclerotic causes of MINOCA (plaque erosion, plaque rupture, and calcified nodule) and nonatherosclerotic causes (spontaneous artery dissection, and spasm). In this review, we summarize the performance of the two intracoronary imaging modalities (IVUS and OCT) in MINOCA and discuss the importance of supplementing these modalities with CMR in order to drive target therapy.

Clinical and psychological characteristics of patients with ischemia and non-obstructive coronary arteries (INOCA) and obstructive coronary artery disease

Study objective

Ischemia with non-obstructive coronary arteries (INOCA) is caused by vascular dysfunctions and predominantly seen in women. For better recognition and prevention more insight is needed on risk factors and well-being. We aimed to explore differences in psychological distress, quality of life, risk factors, and medication use between women with INOCA and obstructive coronary artery disease (CAD).

Methods

Patients from two separate studies (n = 373, 57 % women) completed a questionnaire assessing psychological and clinical factors. Analyses were performed for women only who were categorized into three groups: non-ischemic chest pain (n = 115), INOCA (n = 68), and obstructive CAD (n = 30). Secondary analyses were performed for men only, and sex differences within INOCA patients were explored.

Results and conclusion

Compared to obstructive CAD patients, INOCA patients reported better physical functioning (p = 0.041). Furthermore, INOCA patients had less often hypercholesterolemia (p < 0.001), were less often active smokers (p = 0.062), had a lower mean BMI (p = 0.022), and reported more often a familial history of CAD (p = 0.004). Patients with INOCA used antithrombotic, cholesterol lowering medications, and beta-blockers less often than patients with obstructive CAD. No differences between patients with INOCA and obstructive CAD were found for psychological distress, well-being, and for women-specific risk factors. The results suggest that women with INOCA experience similar levels of psychological distress and seem to have different risk factor profiles and are less optimally treated as compared to obstructive CAD patients. Further research on risk factors is needed for better prevention and treatment.

Depression was associated with younger age, female sex, obesity, smoking, and physical inactivity, in 1027 patients with newly diagnosed type 2 diabetes: a Swedish multicentre cross-sectional study

BACKGROUND

Depression is a risk factor for type 2 diabetes (T2D) and cardiovascular disease (CVD). The aims were to explore the prevalence of depression, anxiety, antidepressant use, obesity, Hemoglobin A1c > 64 mmol/mol, life-style factors, pre-existing CVD, in patients with newly diagnosed T2D; to explore associations with depression; and to compare with Swedish general population data.

METHODS

Multicentre, cross-sectional study.

INCLUSION CRITERIA

adults with serologically verified newly diagnosed T2D. Included variables: age, sex, current depression and anxiety (Hospital Anxiety and Depression Scale), previous depression, antidepressant use, obesity (BMI ≥ 30 and ≥ 40 kg/m²), Hemoglobin A1c, pre-existing CVD. Logistic regression analyses were performed.

RESULTS

In 1027 T2D patients, aged 18-94 years, depression was associated with age (per year) (inversely) (odds ratio (OR) 0.97), anxiety (OR 12.2), previous depression (OR 7.1), antidepressant use (OR 4.2), BMI ≥ 30 kg/m² (OR 1.7), BMI ≥ 40 kg/m² (OR 2.3), smoking (OR 1.9), physical inactivity (OR 1.8), and women (OR 1.6) (all p ≤ 0.013). Younger women (n = 113), ≤ 59 years, compared to younger men (n = 217) had higher prevalence of current depression (31% vs 12%), previous depression (43 vs 19%), anxiety (42% vs 25%), antidepressant use (37% vs 12%), BMI ≥ 30 kg/m² (73% vs 60%) and BMI ≥ 40 kg/m²) (18% vs 9%), and smoking (26% vs 16%) (all p ≤ 0.029). Older women (n = 297), ≥ 60 years, compared to older men (n = 400) had higher prevalence of previous depression (45% vs 12%), anxiety (18% vs 10%), antidepressant use (20% vs 8%), BMI ≥ 30 kg/m² (55% vs 47%), BMI ≥ 40 kg/m² (7% vs 3%) (all p ≤ 0.048), but not of current depression (both 9%). Compared to the Swedish general population (depression (women 11.2%, men 12.3%) and antidepressant use (women 9.8%, men 5.3%)), the younger women had higher prevalence of current depression, and all patients had higher prevalence of antidepressant use.

CONCLUSIONS

In patients with newly diagnosed T2D, the younger women had the highest prevalence of depression, anxiety, and obesity. The prevalence of depression in young women and antidepressant use in all patients were higher than in the Swedish general population. Three risk factors for CVD, obesity, smoking, and physical inactivity, were associated with depression.

Clinical Features and Long-Term Outcomes in Very Young Patients with Myocardial Infarction with Non-Obstructive Coronary Arteries

Background

The main cause of acute coronary syndrome (ACS) is coronary artery obstruction due to atherosclerotic plaque growth or thrombus formation secondary to plaque rupture or erosion. However, there is a subgroup of patients with signs and symptoms suggestive of ACS but without relevant coronary artery obstruction on coronary angiography. This population is defined as myocardial infarction with non-obstructive coronary arteries (MINOCA). The present study analyzes the clinical features and outcomes of very young patients with a diagnosis of MINOCA.

Method

Nested case-control study of ≤40-year-old patients referred for coronary angiography due to clinical suspicion of ACS. Patients were divided into three groups: patients with obstructive coronary artery disease (CAD), patients diagnosed with MINOCA, and controls with non-coronary artery disease.

Results

Of 19,321 coronary angiographies performed in our center in a period of 10 years, 408 (2.1%) were in patients ≤40 years old, and MINOCA was identified in 32 (21%) patients. The cardiovascular risk factors for obstructive CAD and MINOCA were very similar. The incidence of major adverse cardiovascular events (MACE) at follow-up was significantly higher in the MINOCA (HR 4.13 (95%CI 1.22–13.89) and obstructive CAD (HR 4.59 (95%CI 1.90–10.99) patients compared to controls. Cocaine use HR 14.58 (95%CI 3.08–69.02), family history of CAD HR 6.20 (95%CI 1.40–27.43), and depression HR 5.16 (95%CI 1.06–25.24) were associated with a poor outcome in the MINOCA population.

Conclusion

Very young patients with MINOCA had a poor prognosis at long-term follow-up, similar to patients with obstructive CAD. Focusing efforts on secondary prevention is essential in this population.

The e-mental health treatment in Stockholm myocardial infarction with non-obstructive coronaries or Takotsubo syndrome study (E-SMINC): a study protocol for a randomised controlled trial

BACKGROUND

In the aftermath of a myocardial infarction with non-obstructive coronary arteries (MINOCA) or Takotsubo syndrome (TS), patients commonly express high levels of stress and anxiety. Current treatment alternatives rarely address these issues.

METHODS

The study is a randomised controlled trial, where 90 patients with a discharge diagnosis of MINOCA or TS who also report symptoms of stress or anxiety will be randomised 2-6 weeks after their cardiac event. The treatment consists of 10 weeks of Internet-based cognitive behaviour therapy (CBT) and starts immediately after randomisation for the treatment group. The control group receives usual care. Main outcomes are symptoms of anxiety measured with the Hospital Anxiety and Depression scale, anxiety subscale, and perceived stress measured with the Perceived Stress Scale, 14-item version, 10 weeks after randomisation. Secondary measures include cardiac specific anxiety, symptoms of post-traumatic stress, quality of life, cortisol measured in hair and physiological stress responses (heart rate variability, blood pressure and saliva cortisol) during a stress procedure. Ten weeks after randomisation, the control group will also receive treatment. Long-term follow-up in the self-report measures mentioned above will be conducted 20 and 50 weeks after randomisation where the total group's development over time is followed, and the groups receiving intervention early versus late compared.

DISCUSSION

At present, there are no randomised studies evaluating psychological treatment for patients with MINOCA or TS. There is an urgent need for treatment alternatives aiming at relieving stress and anxiety considering the high mental stress and anxiety levels observed in MINOCA and TS, leading to decreased quality of life. CBT aiming at reducing mental stress has been shown to be effective regarding prognosis in patients with coronary artery disease. The current protocol describes a randomised open-label controlled trial evaluating an Internet-based CBT program for reduction of stress and anxiety in patients with increased mental stress and/or anxiety with a discharge diagnosis of either MINOCA or TS.

Effectiveness of Family-Centered Empowerment Model on Psychological Improvement of Patients With Myocardial Infarction: A Bayesian Multivariate Approach

Objective

There is a limited understanding of the impact of the family-centered empowerment model (FCEM) on the psychological symptoms in post-myocardial infarction (MI). This study aimed to evaluate the effectiveness of the FCEM on the psychological improvement of patients with MI.

Methods

The present study was a randomized controlled trial (RCT) where patients experienced a standard home cardiac rehabilitation (CR) or CR utilizing the FCEM approach. The empowerment of patients was estimated during nine assessments, such as pre- and post-intervention. Factors, such as quality of life (QoL), state and trait anxiety, and perceived stress, were evaluated. A Bayesian multivariate mixed-effects model was used to simultaneously investigate the effect of the intervention group on study outcomes across the time.

Results

Among all the participants in this study, 24 (34.3%) were women with a total mean ± standard deviation (SD) of 61.40 ± 12.83 and 24.87 ± 3.80 for age and body mass index (BMI). The participants who were in the FCEM group had a significantly higher mean level of perceived stress (β = 28.80), state anxiety (β = 16.20), trait anxiety (β = 3.65), physical (β = 38.54), and mental QoL (β = 42.14). Moreover, the individuals in the FCEM group had a significantly higher mean level of general health (β = 31.64) in the physical dimension of QoL, vitality (β = 15.04), mental role limitation (β = 21.84), and mental health (β = 18.16) in the mental dimension of QoL.

Conclusions

The FCEM can be a valuable treatment mechanism for patients with post-MI to improve their stress, anxiety, and QoL.

Relationship of Psychiatric Disorders and Sleep Quality to Physical Symptoms in Coronary Artery Disease

ABSTRACT

Psychiatric disorders (depression/anxiety) and sleep quality are linked to coronary artery disease (CAD). CAD patients often complain of various physical symptoms (PSs), which are not only organic changes of biological origin, but also somatization of mental illness. PSs also affect CAD progression. However, the relationship between psychiatric disorders/sleep quality and PS in CAD is less studied, which this study aims to clarify. This cross-sectional observational study was conducted on the first 305 CAD patients diagnosed with PS by Patient Health Questionnaire-15. They were compared with 521 other CAD patients showing no PS. On multivariate analysis, sex, age, family history, psychiatric disorders, and sleep quality were the significant independent predictors of PS. A significant correlation was found between PS severity and the severity of both psychiatric disorders and sleep quality. Further studies are warranted to explore the impact of psychological and sleep intervention on PS and long-term outcomes.

Evidence and Characteristics of Traditional Chinese Medicine for Coronary Heart Disease Patients With Anxiety or Depression: A Meta-Analysis and Systematic Review

Aims: The objective of this study was to assess the efficacy and potential mechanisms of Chinese herbal medicine (CHM) for treating coronary heart disease (CHD) patients with anxiety or depression.

Methods: A systematic literature search was performed. Screening studies, extracting data, and assessing article quality were carried out independently by two researchers. The active ingredients of CHM for the treatment of CHD with anxiety or depression were analyzed by the network pharmacology, and the main potential mechanisms were summarized by the database of Web of Science.

Results: A total of 32 studies were included. The results showed that compared with the blank control groups, CHM was more beneficial in treating anxiety or depression in patients with CHD [anxiety: OR = 3.22, 95% CI (1.94, 5.35), p &lt; 0.00001, I2 = 0%; depression: OR = 3.27, 95% CI (1.67, 6.40), p = 0.0005, I2 = 0%], and the efficacy of CHM was not inferior to that of Western medicine (WM) [anxiety: OR = 1.58, 95%CI (0.39, 6.35), p = 0.52, I2 = 67%; depression: OR = 1.97, 95%CI (0.73, 5.28), p = 0.18, I2 = 33%,]. Additionally, CHM also showed a significant advantage in improving angina stability (AS) in CHD patients with anxiety or depression compared with blank groups [anxiety: SMD = 0.55, 95%CI (0.32, 0.79), p &lt; 0.00001, I2 = 0%; depression: p = 0.004] and WM groups [anxiety: SMD = 1.14, 95%CI (0.80, 1.47), p &lt; 0.00001, I2 = 0%; depression: SMD = 12.15, 95%CI (6.07, 18.23), p &lt; 0.0001, I2 = 0%]. Angina frequency (AF) and electrocardiogram (ECG) analysis after using CHM demonstrated similar trends. Based on the network pharmacology, quercetin, kaempferol, luteolin, beta-sitosterol, puerarin, stigmasterol, isorhamnetin, baicalein, tanshinone IIa, and nobiletin were most closely and simultaneously related to the pathological targets of CHD, anxiety, and depression. The main underlying mechanisms might involve anti-damage/apoptosis, anti-inflammation, antioxidative stress, and maintaining neurotransmitter homeostasis.

Conclusion: CHM exhibited an obvious efficacy in treating CHD patients with anxiety or depression, especially for improving the symptom of angina pectoris. The most active compounds of CHM could simultaneously act on the pathological targets of CHD, anxiety, and depression. Multiple effective components and multiple targets were the advantages of CHM compared with WM.

Myocardial Infarction With Non-obstructive Coronary Arteries: Risk Factors and Associated Comorbidities

Myocardial infarction with non-obstructive coronary arteries (MINOCA), despite a lower burden of coronary atherosclerosis, has a non-negligible prognostic impact. The label of MINOCA includes an array of different aetiologies and pathologic conditions, thus the identification of the underlying disease is crucial to patient management. Myocardial infarction with obstructive coronary artery disease and MINOCA share only some risk factors and comorbid conditions. While traditional cardiovascular risk factors have a lower prevalence in MINOCA patients, atypical ones—e.g., anxiety, depression, and autoimmune diseases—are much more frequent in this population. Other conditions—e.g., pregnancy, cancer, and anti-cancer therapy—can predispose to or even induce MINOCA through various mechanisms. The evidence of such risk factors for MINOCA is still scarce and contradicting, as no randomised controlled trials exist in this field. In our work, we performed a review of registries, clinical studies, and case reports of MINOCA, in order to summarise the available data and analyse its possibile pathogenic mechanisms.

Sexual Function, Anxiety, Depression and Coping After Myocardial Infarction: An Exploratory Study

Background

Myocardial infarction (MI) may decrease sexual function and satisfaction in men and can be influenced by anxiety, depression, and sexual fear. However, few studies have examined short-term changes in sexual function over time in a post-MI population. This study aimed to longitudinally describe changes in sexual function and satisfaction in a sample of men post-MI.

Methods

Eighteen patients were recruited from a Midwestern hospital. Surveys were mailed two weeks and three months post discharge. Sexual function was measured with the Male Sexual Function Index. Other variables collected included sexual fear (Multidimensional Sexuality Questionnaire), anxiety and depressive symptoms (Patient-Reported Outcomes Measurement Information System Anxiety and Depression 4a), and use of coping strategies (Coping Strategy Indicator).

Results

Sexual function scores increased in the entire sample from 8.9 (SD 7.3) at two weeks to 14.6 (SD 8.9) at three months (18.8% improvement, p=0.04). Men who were sexually active improved their scores by 27.3% (p=0.01), while those who were not sexually active decreased their scores by 2.3% (p=0.5). Depressive symptoms and anxiety scores were low and largely stable across timepoints, though there were some improvements among men who were sexually active compared to those who were not. Decreased utilization of avoidance coping strategies was reported in sexually active versus inactive men.

Conclusion

While sexual function improved within a short-time period post discharge among sexually active men post-MI, further research is needed with a larger sample to understand these changes across a longer period. Additional research is also warranted to examine any potential influence of psychosocial predictors.

Mental Stress-Induced Myocardial Ischemia

PURPOSE OF REVIEW

To summarize recent evidence on mental stress-induced myocardial ischemia (MSIMI), its mechanisms, and clinical significance.

RECENT FINDINGS

MSIMI can occur in patients with normal cardiac stress testing, is only weakly related to severity of coronary artery disease (CAD), and it is often silent. Among patients with CAD, MSIMI is associated with a twofold increased risk of major adverse cardiovascular events compared to those who do not have MSIMI. Certain groups such as young women with myocardial infarction and those with psychological comorbidities are more susceptible to MSIMI. Abnormal microvascular vasoreactivity and inflammation are implicated mechanisms in MSIMI. Increased brain activity in regions that modulate autonomic reactivity to emotional stress and fear is associated with MSIMI. MSIMI has important prognostic implications in patients with CAD. Stress can no longer be ignored as a risk factor in cardiology care. Clinical trials testing effective strategies to target MSIMI are needed.

Predictors of sexual function among men after myocardial infarction: a pilot study

Background

Sexual dysfunction often persists among men post-myocardial infarction (MI). While some cross-sectional and longitudinal research has been conducted, there are still no known modifiable targets for intervention. This pilot study aimed to model hypothesized predictive factors of higher sexual function in a cohort of men post-MI.

Methods

In a longitudinal study design, sexual function (Male Sexual Function Index), sexual fear (Multidimensional Sexuality Questionnaire), anxiety and depressive symptoms (Patient-Reported Outcomes Measurement Information System), and utilization of coping strategies (Coping Strategy Indicator) data were collected at two weeks and three months post discharge for MI. Spearman correlations were estimated to examine associations among MSFI scores with the selected predictors at two weeks and three months. Linear regression models were conducted for sexual function while controlling for age.

Results

Fourteen men post-MI were analyzed. The average age of the sample was 59.79 years, 78.6% were married, and all were self-reported White race. Sexual fear and utilization of problem-solving and support-seeking coping strategies were moderately correlated with MSFI scores at three months. Increased use of problem-solving and support-seeking coping strategies were associated with increased sexual function at three months (support-seeking coping 1.47, p<0.01; problem-solving coping 0.95, p=0.02).

Conclusions

Based on these preliminary findings, utilization of coping strategies may predict increased function score over three months. However, additional studies are needed to further examine these hypothesized relationships with a larger more diverse sample. Additional studies are needed of predictors of sexual function among women post-MI.

Designing a Web-Based Psychological Intervention for Patients With Myocardial Infarction With Nonobstructive Coronary Arteries: User-Centered Design Approach

Background

The involvement of patient research partners (PRPs) in research aims to safeguard the needs of patient groups and produce new interventions that are developed based on patient input. Myocardial infarction with nonobstructive coronary arteries (MINOCA), unlike acute myocardial infarction (MI) with obstructive coronary arteries, is presented with no significant obstructive coronary artery disease. Patients with this diagnosis are a subset of those diagnosed with traditional MI and often need more psychological support, something that is presently not established in the current treatment scheme in Swedish health care or elsewhere, to our knowledge. An internet-delivered intervention might offer patients with MINOCA the opportunity to access a psychological treatment that is tailored to their specific needs after MINOCA and could therefore supplement the existing medical care in an easily accessible format.

Objective

This paper aims to describe the development of a therapist-guided, internet-delivered psychological intervention designed specifically for patients with MINOCA.

Methods

The study used a participatory design that involved 7 PRPs diagnosed with MINOCA who collaborated with a team consisting of researchers, cardiologists, and psychologists. Intervention content was developed iteratively and presented to the PRPs across several prototypes, each continually adjusted and redesigned according to the feedback received. The intervention and experience of it were discussed by PRPs in a final meeting and then presented to a panel of 2 clinical psychologists and a cardiologist for further input.

Results

The outcome of the collaboration between PRPs and the research group produced a web-based psychological 9-step program focusing on stress, worry, and valued action. The input from PRPs contributed substantially to the therapy content, homework tasks, interactive activities, multimedia, and design presentation.

Conclusions

Working with PRPs to develop an intervention for people with MINOCA produced a web-based intervention that can be further evaluated with the goal of offering a new psychological treatment option to a patient group currently without one. Direct contribution from PRPs enabled us to obtain relevant, insightful, and valuable feedback that was put towards the overall design and content of the intervention.

Myocardial infarction-induced anxiety-like behavior is associated with epigenetic alterations in the hippocampus of rat

Epidemiological and experimental animal studies indicate that there is a high risk for the incidence of neuropsychiatric disorders suffering from cardiovascular diseases such as myocardial infarction (MI). However, the potential mechanism of this association remains largely unknown. This study sought to evaluate whether epigenetic alterations in the hippocampus is associated with MI-induced anxiety-like behavior in rats. MI was induced by occlusion of the left anterior descending artery in adult female rats. Anxiety-like behavior was examined by elevated plus maze, light-dark box, and open field test. Relative gene and protein levels expression in the hippocampus were tested by qRT-PCR and western blotting, respectively. We found that MI rats exhibited anxiety-like behavior compared with those in controls, and there is a positive correlation between MI and anxiety-like behavior. We also found that MI decreased KDM6B while increased SIRT1 expression in the hippocampus of MI rats relative to those in controls. In addition, MI not only increased levels of IL-1β, bax, and cleaved-caspase 3, but also increased Iba-1 and GFAP expression in the hippocampus, as compared to those in controls, suggesting a promotion of neuro-inflammation and apoptosis in hippocampus. Co-immunoprecipitation assay illustrated that H3K27me3 functioned by counteracting with YAP activation in the hippocampus of MI rats relative to those in controls. Together, these results suggest a potential role of hippocampal epigenetic signaling in MI-induced anxiety-like behavior in rats, and pharmacological targeting KDM6B or SIRT1 could be a strategy to ameliorate anxiety-like behavior induced by MI.

Mechanisms of myocardial infarction with nonobstructive coronary atherosclerosis: a multifaceted play of different actors with guarded prognosis

PURPOSE OF REVIEW

Myocardial infarction (MI) with nonobstructive coronary atherosclerosis (MINOCA) on invasive angiography (stenosis severity <50%) is a heterogenous clinical entity with a prevalence between 6 and 8% of all MI. Whereas the long-term prognosis of MINOCA is not benign, the identification of its underlying mechanism is critical for appropriate risk stratification and tailored secondary prevention strategies.

RECENT FINDINGS

The current review summarizes the contemporary data on the mechanisms, diagnosis, management strategies and outcomes of MINOCA.

SUMMARY

MINOCA is a relatively common form of MI with guarded prognosis. The use of additional diagnostic tests (particularly intracoronary imaging and cardiac magnetic resonance) is paramount to determine the exact cause of MINOCA and implement tailored medical interventions.

The Impact of Psychological Functioning on Cardiovascular Disease

PURPOSE OF REVIEW

We report on recent findings pertaining to the relationship of both negative and positive indicators of psychological functioning with cardiovascular disease (CVD) and briefly describe possible mechanistic pathways to account for these relationships.

RECENT FINDINGS

A body of observational literature suggests that (1) depression is predictive of CVD and is a consequence of CVD; (2) anxiety is related to CVD but the precise nature of this relationship remains unclear; and (3) negative affectivity and Type D personality are constructs that combine aspects of negative psychological functioning that have shown relationships with CVD and are worthy of future investigation. Positive psychological constructs of meaning/purpose and optimism predict better cardiovascular outcomes and other positive psychological constructs have received promising, but limited, attention in the literature. Key remaining questions concern the magnitude and directionality of possible causal relationships as well as the mechanisms accounting for them.

Myocardial Infarction with Nonobstructive Coronary Arteries (MINOCA): A Review of the Current Position

Myocardial infarction with nonobstructive coronary arteries (MINOCA) remains a puzzling clinical entity that is characterized by clinical evidence of myocardial infarction (MI) with normal or near-normal coronary arteries on angiography (stenosis <50%). Major advances in understanding this condition have been made in recent years. The precise pathogenesis is poorly understood and is being studied and examined further. Guidelines indicate that MINOCA is a group of heterogeneous diseases with different mechanisms of pathology. Since there are multiple possible pathological mechanisms, it is not certain that the classical secondary prevention and treatment strategy for MI with obstructive coronary artery disease (MI-CAD) is optimal for MINOCA patients. The prognosis and predictors for MINOCA patients remain unclear. Although the prognosis is slightly better for MINOCA patients than for MI-CAD patients, MINOCA isn't always benign. The aim of this paper was to review the literature and evaluate MINOCA epidemiology, clinical features, etiology, diagnosis, treatment, and prognosis.

Association Between Depression and Outcomes in Chinese Patients With Myocardial Infarction and Nonobstructive Coronary Arteries

Background Myocardial infarction with nonobstructive coronary arteries ( MINOCA ) occurs in ≈10% of all patients with myocardial infarction. Studies on effects of depression on MINOCA outcomes are lacking. Therefore, the aim of this study was to examine the association of depression with clinical outcomes in Chinese patients with MINOCA . Methods and Results We conducted a prospective cohort study of 633 participants with MINOCA and followed up for 3 years. End points were defined as all-cause mortality and cardiovascular events. Diagnosis of depression was ascertained using the psychiatric interview based on the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). During the follow-up period, all-cause death occurred in 93 individuals and cardiovascular events developed in 170 individuals. Kaplan-Meier curves showed a significant association of depression with all-cause mortality (log-rank P<0.001) and cardiovascular events (log-rank P<0.001). Multiple Cox regression identified the new diagnosis of depression as an independent prognostic factor for all-cause mortality as well as cardiovascular events (adjusted hazard ratio, 7.250; 95% CI, 4.735-11.100; P<0.001; and hazard ratio, 3.411; 95% CI , 2.490-4.674; P<0.001, respectively). Conclusions The new diagnosis of depression at the time of myocardial infarction is associated with increased risk of adverse clinical outcomes in patients with MINOCA.

Association between anxiety and clinical outcomes in Chinese patients with myocardial infarction in the absence of obstructive coronary artery disease

BACKGROUND

Myocardial infarction in the absence of obstructive coronary artery disease (MINOCA) accounts for approximately 5% - 6% of acute myocardial infarction (AMI) patients. Anxiety symptoms are common in patients with coronary artery disease (CAD), and are associated with a poor prognosis. However, the association between anxiety and MINOCA outcomes is less clear.

HYPOTHESIS

Anxiety will be associated with clinical outcomes in patients with MINOCA.

METHODS AND RESULTS

Between November 2014 and December 2016, 620 hospitalized patients with MINOCA were recruited from a single center. Within 7 days of coronary angiography, anxiety was assessed using the Zung Self-Rating Anxiety Scale. The primary endpoint was all-cause mortality; secondary endpoint was any major adverse cardiovascular event (MACE). After 3 years, 87 deaths and 151 MACE had occurred. Kaplan-Meier curves indicated the unadjusted rates of all-cause mortality (log-rank P = .045) and MACE (log-rank P = .023) were significantly higher in the anxiety group compared with the control group of patients without anxiety. Multivariate Cox regression analysis showed that clinically significant anxiety was an independent prognostic factor for all-cause mortality as well as MACE (hazard ratio [HR] = 1.547; 95% confidence interval [CI], 1.006-2.380; P = .047; HR = 1.460; 95% CI, 1.049-2.031; P = .025; respectively).

CONCLUSIONS

Anxiety is significantly and independently associated with an increased risk of all-cause mortality and MACE in patients with MINOCA.

Benchmarking of a checklist for the identification of familial risk for breast and ovarian cancers in a prospective cohort

The detection of deleterious germline mutations in BRCA1 and BRCA2 considerably influences the clinical management of healthy and diseased carriers. Therefore, the identification of persons at risk who could uptake genetic counseling and testing is pivotal. We developed a checklist with validated criteria to improve the identification, and prospectively evaluate the incidence, of familial cancer history in 5091 breast cancer patients. The rate of 30.4% of patients at high genetic risk underpins the demand for care in risk identification and counseling. The easy-to-use instrument promotes the implementation and dissemination of risk counseling by physicians.

Coronary Artery Spasm, Coronary Reactivity, and Their Psychological Context

Symptomatic individuals suspected of having myocardial ischemia often have no obstructive atherosclerotic narrowing of epicardial coronary arteries. Abnormal coronary vascular reactivity and, in particular, coronary artery vasospasm (CAS) may be an explanation in a subset of these patients. Psychological factors play an important role in ischemic heart disease, but their role in CAS is not clear; autonomic dysfunction and increased inflammation are two prevailing pathophysiological mechanisms implicated in abnormal coronary reactivity resulting from mental health conditions. Interrelationships between psychological factors, abnormal coronary reactivity, and sex/gender differences are poorly defined in the etiology of CAS. In this issue of Psychosomatic Medicine (2019;81:237-245), Hung et al. report a frequency of less than 0.1% of new-onset CAS in the Taiwanese population, with higher occurrence in women and younger individuals. Patients with CAS had a higher prevalence of previous anxiety and depression compared with those with coronary artery disease and controls, with no sex differences. In this editorial comment, we discuss the potential reasons for underreporting of CAS and the challenges regarding the use of administrative health records for psychosomatic research. In this editorial, a model is presented to explain the association between emotional stressors and mental health factors with CAS, including the role of sympathetic nervous system activation, inflammation, oxidative stress, endothelial dysfunction, and smooth muscle cell dysregulation.
