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

Knowledge domain and emerging trends in anxiety and depression after myocardial infarction research during 2002-2022: Bibliometric and visualized analysis

Purpose

This study aimed to analyze developmental trends in anxiety and depression after myocardial infarction (ADMI) research in the past 20 years through bibliometrics analysis and predict future research directions.

Methods

ADMI-related publications were retrieved from the Web of Science Core Collection. Bibliometric, VOSviewer, CiteSpace, and Bibliometrix software packages were used for bibliometric analysis and visualization.

Results

Overall, 3220 ADMI-related publications were identified. The United States, China, and the Netherlands were the countries with the most publications. Carney RM, De Jonge P, and Blumenthal JA were the most influential researchers. In 2004, Van Melle JP, from the University of Groningen, published in Psychosomatic Medicine the most cited article. "Cardiac rehabilitation" was the primary focus area. "Cardiac rehabilitation," "management," "acute coronary syndrome," and "outcome" were the top four keywords in emerging research hotspots. Notably, the effect of traditional Chinese medicine on ADMI is an area of potential research value.

Conclusion

Numerous studies have underscored the significance of cardiac rehabilitation. Present research focuses on managing anxiety and depression post-acute coronary syndrome and enhancing clinical outcomes through cardiac rehabilitation technology. Additionally, the therapeutic potential of traditional Chinese medicine for ADMI is expected to attract increased attention from researchers in the future.

Health-related quality-of-life up to one year after myocardial infarction with non-obstructive coronary arteries

AIMS

Patients with Myocardial Infarction with Non-Obstructive Coronary Arteries (MINOCA) are a heterogenous group and previous studies indicate a decreased Health-related quality-of-life (HRQoL) compared with patients with myocardial infarction with obstructive coronary artery disease and healthy individuals. However, longitudinal data are scarce. Therefore, the aim was to explore HRQoL among patients with MINOCA during a one-year period after the acute event in comparison with a group of healthy individuals and to describe HRQoL in patients with Takotsubo Syndrome (TTS).

METHODS AND RESULTS

Patients with MINOCA were recruited from five hospitals in the Stockholm region (SMINC-2 study, clinical trials: NCT2318498). Patients responded to the HRQoL questionnaire RAND-36 between days 2-4, after 6 and 12 months respectively. A sample of population-based individuals was used as a comparison group. A total of 142 MINOCA patients, (70% women) mean age of 56 years, responded. A population-based sample of 317 volunteers (66% women) mean age of 57 years. Patients with MINOCA scored lower than the comparison group in the domains role functioning physical, social functioning, and role functioning emotional (P = 0.01-0.02) at 12 months. In these domains of HRQoL there was no improvement in MINOCA patients during 12 months follow-up. In the domains of energy/fatigue vitality and emotional well-being the scores improved and were similar to the comparison group at 12 months. Patients with TTS scored generally lower on RAND-36 than MINOCA patients without TTS.

CONCLUSION

Physical, social, and emotional functioning did not improve during the first year after MINOCA, indicating a need for increased follow-up including psychological support.

Cardiac Magnetic Resonance Imaging (CMRI) Applications in Patients with Chest Pain in the Emergency Department: A Narrative Review

CMRI is the exclusive imaging technique capable of identifying myocardial edema, endomyocardial fibrosis, pericarditis accompanied by pericardial effusions, and apical thrombi within either the left or right ventricle. In this work, we examine the research literature on the use of CMRI in the diagnosis of chest discomfort, employing randomized controlled trials (RCTs) to evaluate its effectiveness. The research outlines the disorders of the chest and the machine learning approaches for detecting them. In conclusion, the study ends with an examination of a fundamental illustration of CMRI analysis. To find a comprehensive review, the Scopus scientific resource is analyzed. The issue, based on the findings, is to distinguish ischemia from non-ischemic cardiac causes of chest pain in individuals presenting with sudden chest pain or discomfort upon arrival at the emergency department (ED). Due to the failure of conventional methods in accurately diagnosing acute cardiac ischemia, individuals are still being inappropriately discharged from the ED, resulting in a heightened death rate.

Evaluating anxiety in elective coronary angiography study: rationale, design, and study methodology

AIMS

Prevalence of anxiety disorder in coronary artery disease reaches up to 15% and about half of patients with coronary artery disease have anxiety or depression comorbidity. Prevalence of anxiety in patients undergoing percutaneous coronary intervention ranges 24-72%. Depression can often overlap with anxiety symptoms and the evaluation of anxiety in elective coronary angiography study (ANGST) aims to determine the prevalence of anxiety by excluding patients with comorbid depressive symptoms. ANGST also aims to determine how anxiety correlates with psychological parameters (personality traits, coping strategies) and with outcome of elective coronary angiography (ECA).

METHODS

We will conduct a prospective single-center cross-section study in patients undergoing ECA. Anxiety will be evaluated at four time points using self-rating questionnaires: 14 days prior to ECA; 2-4 h before ECA; 24 h after ECA, but prior to discharge; and 4-6 weeks after discharge. The primary outcome of ANGST is the burden of anxiety experienced by patients without depressive symptoms and a correlation of anxiety with ECA outcome.

CONCLUSION

Our study aims to provide evidence on which personality traits and coping strategies affect the levels of anxiety. We will also determine psychometric properties of the two questionnaires used in our study. The results will have implications for improvement of interventions designed to recognize anxiety and will offer future research of psychological and/or pharmacological interventions to reduce the burden of anxiety.

Sleep Quality, Sleep Duration, and the Risk of Adverse Clinical Outcomes in Patients With Myocardial Infarction With Non-obstructive Coronary Arteries

Background

Myocardial infarction with non-obstructive coronary arteries (MINOCA) is a heterogeneous entity with varying underlying etiologies and occurs in ~5–10% of patients with acute myocardial infarction. Sleep disorders and short sleep duration are common phenomena experienced by patients with coronary heart disease and are associated with poor clinical outcomes. However, the association between sleep quality, sleep duration, and the MINOCA prognosis is less clear.

Methods

We performed a prospective observational study of 607 patients with MINOCA between February 2016 and June 2018. The mean follow-up period was 3.9 years. Sleep quality and sleep duration were measured by the Chinese version of the Pittsburgh Sleep Quality Index. The primary endpoint was all-cause mortality, and the secondary endpoint was major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, stroke and heart failure hospitalization.

Results

During the follow-up period, all-cause death occurred in 69 participants and 105 participants developed MACE. The Kaplan–Meier survival analysis demonstrated a significant association between poor sleep quality and all-cause mortality (log-rank P = 0.005) and MACE (log-rank P = 0.004). Multivariable Cox regression model indicated that poor sleep quality was an independent predictor of all-cause mortality as well as MACE [adjusted hazard ratio (HR) = 1.649; 95% confidence interval (CI), 1.124–2.790; P < 0.001; and adjusted HR = 1.432; 95% CI, 1.043–2.004; P = 0.003, respectively]. For sleep duration, short sleep duration (<6 h/d) was significantly associated with an increased risk of all-cause mortality and MACE (adjusted HR = 1.326; 95% CI, 1.103–1.812; P = 0.004; and adjusted HR = 1.443; 95% CI, 1.145–1.877; P < 0.001, respectively), whereas long sleep duration was not (>8 h/d). A poorer sleep profile (including poor sleep quality and short sleep duration) was associated with a 149.4% increased risk of death (HR = 2.494; 95% CI, 1.754–4.562; P < 0.001) and a 96.7% increased risk of MACE (HR = 1.967; 95% CI, 1.442–3.639; P < 0.001) than those with neither.

Conclusion

Sleep disorders were common among Chinese patients with MINOCA. Poor sleep quality and short sleep duration were independently associated with an increased risk of all-cause mortality and MACE in the MINOCA population. Meanwhile, a poor sleep profile has an additive effect with regard to cardiovascular risks; in these populations, efforts should be made to improve both sleep quality and sleep duration for secondary cardiovascular prevention.

"Acute Myocardial Infarction in the Time of COVID-19": A Review of Biological, Environmental, and Psychosocial Contributors

Coronavirus disease 2019 (COVID-19) has quickly become a worldwide health crisis.Although respiratory disease remains the main cause of morbidity and mortality in COVID patients,myocardial damage is a common finding. Many possible biological pathways may explain therelationship between COVID-19 and acute myocardial infarction (AMI). Increased immune andinflammatory responses, and procoagulant profile have characterized COVID patients. All theseresponses may induce endothelial dysfunction, myocardial injury, plaque instability, and AMI.Disease severity and mortality are increased by cardiovascular comorbidities. Moreover, COVID-19has been associated with air pollution, which may also represent an AMI risk factor. Nonetheless,a significant reduction in patient admissions following containment initiatives has been observed,including for AMI. The reasons for this phenomenon are largely unknown, although a real decreasein the incidence of cardiac events seems highly improbable. Instead, patients likely may presentdelayed time from symptoms onset and subsequent referral to emergency departments because offear of possible in-hospital infection, and as such, may present more complications. Here, we aim todiscuss available evidence about all these factors in the complex relationship between COVID-19and AMI, with particular focus on psychological distress and the need to increase awareness ofischemic symptoms.

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.
