The Quality of Symptoms in Women and Men Presenting to the Emergency Department With Suspected Acute Coronary Syndrome

Enhancing predictive accuracy of the 13-item Acute Coronary Syndrome checklist: a novel approach to improving risk assessment and diagnosis

OBJECTIVES

This study aimed to evaluate the discriminatory capacity of the 13-Item ACS checklist and improve the accuracy of ACS diagnosis through the application of weighted regression analysis.

MATERIALS AND METHODS

This predictive correlation study enrolled 300 patients admitted to Emergency Department between February 2021 and January 2022. The ACS checklist was administered upon initial triage, followed by patient tracking over a one-month hospitalisation period, capturing ACS diagnoses. Data analysis employed STATA 17 and MEDCALC 20.0.13 software.

RESULTS

Findings indicated that patients with sweating and shortness of breath symptoms had a heightened likelihood of true ACS diagnosis by 14% and 11%, respectively, compared to those without ACS (p = 0.005 and 0.019). Conversely, palpitations were associated with a 20% decreased likelihood of authentic ACS diagnosis (p < 0.001). Integration of significant regression coefficients - palpitation severity (-21), sweating severity (13.7), and shortness of breath severity (11) demonstrated significant discriminatory enhancements in the checklists. The weighted 13-item ACS checklist surpassed the unweighted version's performance, yielding superior discriminatory power for ACS diagnosis (p < 0.001 and p = 0.089). The weighted checklist elevated the AUC score from 55% to 70%.

CONCLUSIONS

Incorporating weighted factors - shortness of breath severity, sweating severity, and palpitations severity - into the checklist notably enhanced ACS identification. However, it's important to note that this tool, while showing promise, is not intended to serve as a standalone diagnostic tool for ACS. Instead, this tool has the potential to enhance risk assessment and aid in clinical decision-making.

The impact of the COVID-19 pandemic on cardiac related emergency department presentations: A scoping review

BACKGROUND

Acute cardiac conditions require timely assessment and management to optimise patient outcomes. It is important to understand whether changes in acute cardiac ED visits occurred in relation to the COVID-19 pandemic.

OBJECTIVE

To provide a comprehensive synthesis of published articles regarding the impact of the pandemic on acute cardiac-related ED presentations in terms of rates, patient demographics, ED clinical characteristics, and outcomes.

METHODS

A scoping review using the Joanna Briggs Institute methodology was undertaken. Four databases (Ovid MEDLINE, CINAHL, Scopus, and the Public Health Database (ProQuest)) were searched for articles published in English between 1 January 2020 and 30 April 2022 that reported on acute cardiac-related ED presentation rates, comparing COVID-19 pandemic and non-pandemic time periods, for adult patients (18 years and over), and demographics, and/or presentation characteristics, and/or outcomes.

RESULTS

Sixteen articles met the inclusion criteria. There was a significant decline in ED presentations for heart failure and myocardial infarction during 2020. Demographic, presentation characteristics and outcomes were inconsistently reported.

CONCLUSION

While there is variation and heterogeneity in the current available evidence, this data is helpful for informing clinicians and policy makers for future pandemics as well as providing a reference point for COVID-19 related research.

Emergency Nurses' Recognition of and Perception of Sex Differences in Acute Coronary Syndrome Symptoms

INTRODUCTION

Emergency nurses must quickly identify patients with potential acute coronary syndrome. However, no recent nationwide research has explored nurses' knowledge of acute coronary syndrome symptoms. The purpose of this study was to explore emergency nurses' recognition of acute coronary syndrome symptoms, including whether nurses attribute different symptoms to women and men.

METHODS

We used a cross-sectional, descriptive design using an online survey. Emergency nurses from across the United States were recruited using postcards and a posting on the Emergency Nurses Association website. Demographic data and participants' recognition of acute coronary syndrome symptoms, using the Acute Coronary Syndrome Symptom Checklist, were collected. Descriptive statistics and ordinal regression were used to analyze the data.

RESULTS

The final sample included 448 emergency nurses with a median 7.0 years of emergency nursing experience. Participants were overwhelmingly able to recognize common acute coronary syndrome symptoms, although some symptoms were more often associated with women or with men. Most participants believed that women and men's symptoms were either "slightly different" (41.1%) or "fairly different" (42.6%). Nurses who completed training for the triage role were significantly less likely to believe that men and women have substantially different symptoms (odds ratio 0.47; 95% CI 0.25-0.87).

DISCUSSION

Emergency nurses were able to recognize common acute coronary syndrome symptoms, but some reported believing that the symptom experience of men and women is more divergent than what is reported in the literature.

Effect of triage training on nurses' practice and triage outcomes of patients with acute coronary syndrome

BACKGROUND

Accurate assessment and prompt management of patients with acute coronary syndrome (ACS) is a complex process for emergency department (ED) nurses and has variable clinical outcomes. The aim of the present study was to determine the effectiveness of an educational intervention on nurses' practice during the triage of patients with ACS and the triage outcomes in this group of patients.

METHODS

In this quasi-experimental study, a pretest-posttest group of 24 nurses were included by convenience sampling method and 960 patients with ACS were selected by sequential sampling during the pre-intervention (n = 480) and post-intervention (n = 480) phases. A case-based learning (CBL) intervention was performed for nurses for one month considering the role of the triage nurse according to the American College of Cardiology (ACC) and the American Heart Association (AHA) recommendations as well as the factors affecting the proper identification and management of patients with ACS. During patient triage in the pre- and post-intervention phases, the "Triage Nurse Practice Checklist" and the "Medical Electronic Records" were used to assess nurses' practice and the triage outcomes in patients, respectively.

RESULTS

The overall mean score of the triage nurses' practice and its subscales, including Primary monitoring and assessment, cardiovascular risk factors assessment, evaluation of coronary heart disease (CHD) symptoms, chest pain management, and adherence to the ACC/AHA practice guidelines were significantly improved in the post-intervention phase compared with the pre-intervention phase (p < 0.001). There was no significant difference between the triage outcomes, including in-hospital mortality within 24 hours, death in ED, hospitalization in other wards, and discharge from ED in the pre and post-intervention phases (P = 0.723).

CONCLUSION

The development of a cardiac triage-specific educational program could improve the performance of nurses in the evaluation and management of patients with ACS, but had no effect on the triage outcomes in this group of patients. We recommend a quality improvement project or a critical outcomes-based triage system to assess ACS patients' care needs in the ED.

Symptom recognition and treatment-seeking behaviors in women experiencing acute coronary syndrome for the first time: a qualitative study

BACKGROUND

Women are more likely to delay medical help-seeking for ACS symptoms. Understanding patients' experience of the symptoms and their response is essential in improving help-seeking behaviors and timely diagnosis and treatment for ACS. This study aimed to explore women's experience of ACS, their response to the symptoms, and treatment-seeking decisions.

METHODS

This qualitative descriptive study was conducted in a tertiary referral specialized heart hospital affiliated with Tabriz University of Medical Sciences, Iran. Participants included 39 women who had experienced ACS for the first time.

RESULTS

Four main themes emerged from the analysis of interview transcripts: (1) the onset of symptoms, (2) the types of symptoms, (3) response to symptoms and (4) arriving at the hospital. These themes and associated sub-themes explained women's experience of ACS symptoms, their response to the symptoms, and decision to seek medical help.

CONCLUSIONS

This study identified and discussed factors contributing to the prehospital delay in women and their decision-making to seek medical care for ACS symptoms. The results are consistent with previous research indicating that ACS symptoms in women are somewhat different from men, and women tend to underestimate their symptoms and attribute them to non-cardiac causes. Women should be supported to develop awareness and understanding of ACS symptoms and appreciate the importance of early treatment-seeking in the disease outcomes.

Effect of aromatherapy with Melissa essential oil on stress and hemodynamic parameters in acute coronary syndrome patients: A clinical trial in the emergency department

Stress and hemodynamic changes are among the most significant symptoms and signs that could be observed in patients with acute coronary syndrome (ACS) upon admission to the emergency department. The present study was conducted to determine the effect of the fragrance of lemon balm (Melissa Officinalis) essential oil on stress level and hemodynamic parameters in patients with ACS in the emergency department.

METHODS

In this double-blind clinical trial, 72 patients were allocated to two groups of Melissa and placebo based on stratified block random sampling. The Melissa group inhaled two drops of Melissa essential oil, whereas the placebo group inhaled two drops of sunflower oil in two aromatherapy phases for 10 min with 90-min intervals. Stress level was measured using the depression, anxiety and stress scale (DASS-21), and hemodynamic parameters were measured and recorded in six time points by a cardiac monitoring system. Data analysis was carried out using descriptive statistics and ANOVA statistical tests, Chi-square test, independent t-test, and post-hoc Tukey's test.

RESULTS

Interaction between the time and group indicated the significant decrease in the mean score of stress and heart rate in the time points 2 and 5 (5 min after every occasion of aromatherapy) (p < 0.001) and also the remarkable decrease in the mean arterial pressure (MAP) in the time point 2 in the Melissa group in comparison with the placebo group (p < 0.001). There were no significant differences between the mean changes in stress, heart rate and MAP in the two group (P > 0.05).

CONCLUSION

Aromatherapy via the inhalation of Melissa essential oil with temporary impacts on certain time points could relieve stress and regulate hemodynamic changes in patients with ACS in emergent and acute conditions.

Characteristic differences of chest pain in male and female patients with acute coronary syndrome: A pilot study

Background: The typical sign or main symptom in acute coronary syndrome (ACS) patients is chest pain, which is an initial benchmark or early sign for diagnosis. Certain factors, such as gender differences, the presence of diabetes mellitus or other clinical conditions, may make the patient not realize they have ACS. Therefore, this study aims to identify the characteristics of chest pain symptoms in male and female patients with ACS.

Design and Methods: This is a non-experimental quantitative study, namely analytical observation using a cross-sectional approach within 4 months (January-April 2019). Furthermore, the samples were 53 ACS patients (28 male and 25 female).

Results: The chest pain characteristics that have a significant relationship with gender differences in ACS patients are shown based on the aspects of location, pain duration and quality. Male patients are more likely to feel pain at the left or middle chest, the duration is between <20 to >20 min with moderate pain quality, which tends to become severe, while females are more likely to feel pain at the chest which radiates to the neck and chin, the duration is usually >20 min, with mild to moderate pain quality.

Conclusions: The result showed a significant difference in chest pain characteristics in male and female patients with ACS. Regarding location, duration and quality of chest pain, male ACS patients mostly have more typical symptoms, while females’ symptoms are atypical.
