RESUMO

BACKGROUND: Hazardous drugs are inherently toxic and present a potential occupational exposure risk to nurses and midwives. Hazardous drugs require special handling to minimise the risk of exposure and adverse health effects. Although the use of hazardous drugs in oncology services is well recognised, they are also used in other healthcare areas where nurses and midwives may be unaware there is a risk. OBJECTIVE: To investigate what nurses and midwives know and do about their occupational exposure to hazardous drugs, and what factors affect their knowledge and practice. DESIGN: Mixed methods systematic review. METHODS: A systematic review was conducted, and studies were included if the authors described what nurses or midwives knew about hazardous drugs, or what they did in their clinical practice to reduce their risk of occupational exposure (PROSPERO registration CRD42024437493). The databases were searched for any year until the 26th of January 2024.Two independent reviewers extracted data using Covidence and assessed the risk of bias. The data were extracted into the categories of knowledge of risk and safe handling practices, attitude and factors affecting these, and activities that posed the greatest risk of exposure (preparation, administration, and disposal of hazardous drugs, cleaning hazardous drug spills, and handling excreta from patients who had recently been treated with hazardous drugs). RESULTS: Of the 2702 articles that were identified, 59 quantitative and 3 qualitative studies were included in this review. No studies reported on midwives handling hazardous drugs. Most studies investigated nurses working in oncology services. Nurses reported a lack of education about the risk and safe handling. They were often responsible for preparing hazardous drugs and there was inconsistency in their compliance when using personal protective equipment. Nurses did not always perceive that there was a real risk of exposure, were concerned about the effect of wearing personal protective equipment on their relationship with patients and perceived they lacked the time to don equipment. CONCLUSIONS: The risk of occupational exposure to hazardous drugs outside of oncology services was rarely investigated. There were no studies reporting what midwives knew and did about their risk of occupational exposure to hazardous drugs. When nurses were aware of the risks, this did not necessarily translate into the implementation of safe handling practices or the consistent use of personal protective equipment because of a perceived low risk, lack of personal protective equipment availability, and prioritising personal or patient comfort over safety measures. TWEETABLE ABSTRACT: Nurses and midwives are often unknowingly exposed to the toxic effects of hazardous drugs when they prepare and administer these drugs for patients, although knowledge does not always equal safe handling practices.

RESUMO

BACKGROUND: Emergency Department (ED) care is provided for a diverse range of patients, clinical acuity and conditions. This diversity often calls for different vital signs monitoring requirements. Requirements often change depending on the circumstances that patients experience during episodes of ED care. AIM: To describe expert consensus on vital signs monitoring during ED care in the Australasian setting to inform the content of a joint Australasian College for Emergency Medicine (ACEM) and College of Emergency Nursing Australasia (CENA) position statement on vital signs monitoring in the ED. METHOD: A 4-hour online nominal group technique workshop with follow up surveys. RESULTS: Twelve expert ED nurses and doctors from adult, paediatric and mixed metropolitan and regional ED and research facilities spanning four Australian states participated in the workshop and follow up surveys. Consensus building generated 14 statements about vital signs monitoring in ED. Good consensus was reached on whether vital signs should be assessed for 15 of 19 circumstances that patients may experience. CONCLUSION: This study informed the creation of a joint position statement on vital signs monitoring in the Australasian ED setting, endorsed by CENA and ACEM. Empirical evidence is needed for optimal, safe and achievable policy on this fundamental practice.

RESUMO

OBJECTIVE: Escalating global challenges (such as disasters, conflict, and climate change) underline the importance of addressing Chemical, Biological, Radiological, and Nuclear (CBRN) terrorism for sustainable public health strategies. This study aims to provide a comprehensive epidemiological analysis of CBRN incidents in the Middle East and North Africa (MENA) region, emphasizing the necessity of sustainable responses to safeguard healthcare infrastructures. METHOD: Utilizing a retrospective approach, this research analyzes data from the Global Terrorism Database (GTD) covering the period from 2003 to 2020. The study focuses on examining the frequency, characteristics, and consequences of CBRN incidents in the MENA region to identify patterns and trends that pose significant challenges to public health systems. RESULTS: The analysis revealed a significant clustering of CBRN incidents in Iraq and Syria, with a predominant involvement of chemical agents. These findings indicate the extensive impact of CBRN terrorism on healthcare infrastructures, highlighting the challenges in providing immediate health responses and the necessity for long-term recovery strategies. CONCLUSIONS: The study underscores the need for improved healthcare preparedness, robust emergency response systems, and the development of sustainable public health policies. Advocating for international collaboration, the research contributes to the strategic adaptation of healthcare systems to mitigate the impacts of CBRN terrorism, ensuring preparedness for future incidents in the MENA region and beyond.

RESUMO

INTRODUCTION: An understanding of emergency nurses' roles, challenges, and preparedness in the context of armed conflict is necessary to capture in-depth insights into this specialty and their preparational needs when working in these unique environments. Unfortunately, the evidence about emergency nurses' work in the context of armed conflict is scant. METHOD: Semi-structured interviews were conducted with 23 participants and analyzed using qualitative content analysis. The COREQ guideline for reporting qualitative research was followed. RESULTS: The emergency nurses' roles, challenges, and preparedness in hospitals in the context of armed conflict were explored in detail. The main challenges that these nurses faced included poor orientation, access block, and communication barriers. Various perspectives about preparation, including education, training, and strategies for preparing emergency nurses were identified. The most striking findings in these settings were the diversity of armed conflict injuries, clinical profiles of patients, triage of mass casualties, trauma care, surge capacity, orientation, communication, and strategies for preparing nurses. CONCLUSIONS: This study provided an exploration of the scope of emergency nurses' roles, and how they were prepared and expected to function across multiple hospitals in armed conflict areas. The resultant snapshot of their experiences, challenges, and responsibilities provides an informative resource and outlines essential information for future emergency nursing workforce preparedness. There is a broad range of preparational courses being undertaken by emergency nurses to work effectively in settings of armed conflict; however, required education and training should be carefully planned according to their actual roles and responsibilities in these settings.

RESUMO

INTRODUCTION: Survivors of stroke are at risk of experiencing subsequent major adverse cardiovascular events (MACE). We aimed to determine the incidence of, and risk factors for, MACE after first-ever ischemic stroke, by age group (18-64 years vs. ≥65 years). METHODS: Observational cohort study using patient-level data from the Australian Stroke Clinical Registry (2009-2013), linked with hospital administrative data. We included adults with first-ever ischemic stroke who had no previous acute cardiovascular admissions and followed these patients for 2 years post-discharge, or until the first post-stroke MACE event. A Fine-Gray sub-distribution hazard model, accounting for the competing risk of non-cardiovascular death, was used to determine factors for incident post-stroke MACE. RESULTS: Among 5,994 patients with a first-ever ischemic stroke (median age 73 years, 45% female), 17% were admitted for MACE within 2 years (129 events per 1,000 person-years). The median time to first post-stroke MACE was 117 days (89 days if aged <65 years vs. 126 days if aged ≥65 years; p = 0.025). Among patients aged 18-64 years, receiving intravenous thrombolysis (sub-distribution hazard ratio [SHR] 0.51 [95% CI, 0.28-0.92]) or being discharged to inpatient rehabilitation (SHR 0.65 [95% CI, 0.46-0.92]) were associated with a reduced incidence of post-stroke MACE. In those aged ≥65 years, being unable to walk on admission (SHR 1.33 [95% CI 1.15-1.54]), and history of smoking (SHR 1.40 [95% CI 1.14-1.71]) or atrial fibrillation (SHR 1.31 [95% CI 1.14-1.51]) were associated with an increased incidence of post-stroke MACE. Acute management in a large hospital (>300 beds) for the initial stroke event was associated with reduced incidence of post-stroke MACE, irrespective of age group. CONCLUSIONS: MACE is common within 2 years of stroke, with most events occurring within the first year. We have identified important factors to consider when designing interventions to prevent MACE after stroke, particularly among those aged <65 years.

RESUMO

BACKGROUND: Armed conflicts are usually associated with high mortality and morbidity rates, with unpredictable workload, injuries and illnesses. Identifying emergency nurses' views of the core competencies required to enable them to work effectively in hospitals in areas of armed conflict is critical. It is important to inform the requisite standards of care and facilitate the translation of knowledge into safe, quality care. AIM: The aim of this study was to identify emergency nurses' perceptions of core competencies necessary to work in hospitals in the context of armed conflict. METHOD: A descriptive qualitative phase of a mixed-method study using semi-structured interviews with participants was conducted from June to July 2019. The COREQ guideline for reporting qualitative research was followed. FINDINGS: A sample of 15 participants was interviewed. The participant perceptions provided a different perspective of core competencies required for emergency nurses in the context of armed conflict, culminating in four main areas: (i) personal preparedness , (ii) leadership, (iii) communication and (iv) assessment and intervention. CONCLUSION: This study identified emergency nurses' perceptions of their core competencies. Personal preparedness, leadership, communication, assessment and intervention were identified as contributing to calmness of character, confidence in care and cultural awareness for care in this setting and were essential for them to work effectively when managing victims of armed conflict in emergency departments. IMPLICATIONS FOR NURSING PRACTICE AND HEALTH POLICY: The findings of this study are important and novel because the researchers sought the perspectives of emergency nurses who have experience in receiving patients from armed conflict firsthand. The findings will inform policymakers in those settings regarding standard of care, education and drills for hospital nurses in optimizing armed conflict care response outcomes.

RESUMO

AIM: To identify nurses' perspectives of their core competencies for emergency care in the context of armed conflict. INTRODUCTION: Emergency department's (ED) capacity is frequently overwhelmed by a sudden surge of patients when located near armed conflict. Although emergency nurses are key frontline responders, evidence detailing core competencies needed to work in these areas remains limited. METHOD: The study used a cross-sectional survey design and is reported using STROBE guidelines. A validated questionnaire was administered in hospitals near the southern Kingdom of Saudi Arabia and Yemen border, where emergency nurses regularly manage large numbers of patients from armed conflict. RESULT: A total of 163 questionnaires were returned (68% response rate). Most participants were female and had more than six years of ED experience. The core competencies for emergency nurses working near armed conflict were identified and highly rated by participants: the highest mean value was 9.47/10 and the lowest was 8.89/10. Analysis revealed regular education, training and drills were needed to provide quality emergency nursing care for victims of armed conflict. CONCLUSION AND IMPLICATIONS FOR NURSING AND HEALTH POLICY: This study provides new evidence regarding core competencies in emergency nursing care in the context of armed conflict. The identified competencies should be incorporated into future education, curricula, training programmes and evaluations to enable emergency nurses to function effectively in the context of armed conflict. The findings will assist decision-makers to develop plans and strategies for mitigating risk and improving the future nursing response in similar contexts.

RESUMO

OBJECTIVE: The primary objective was to determine rapid rule-out (RRO) criteria for the outcome of myocardial infarction (MI) using the Beckman Coulter Access high-sensitivity cardiac troponin I (hs-cTnI) assay. Secondary objectives were to explore cut-points for rapid rule-in (RRI) and amount of change at 3-h (3-h delta) indicative of MI. METHODS: A retrospective study included ED patients with suspected MI between June and September 2019. hs-cTnI levels were performed at baseline and after 3 h. The performance benchmark for RRO criteria was a negative predictive value (NPV) for MI with a lower 95% confidence limit >99%, and for RRI and 3-h delta cut-points was a positive predictive value (PPV) for MI >70%. Delta calculation required rising hs-cTnI levels, with at least one above the 99th percentile of the upper reference limit. Analyses utilised receiver operating characteristic (ROC) curves and contingency tables. RESULTS: Baseline hs-cTnI levels from 935 patients were available for RRO analyses. Of tested criteria, baseline hs-cTnI <6 ng/L (females) or <11 ng/L (males) plus symptom onset >2 h met the performance benchmark (NPV: 100% [95% confidence interval 99-100]). hs-cTnI levels were available for RRI and 3-h delta analyses from 935 and 52 patients, respectively. A 3-h delta cut-point >35 ng/L met the performance benchmark (PPV: 81% [95% confidence interval 58-95]) but no RRI cut-point did so. CONCLUSIONS: For the Beckman Coulter Access hs-cTnI assay, RRO criteria of baseline hs-cTnI <6 ng/L (females) or <11 ng/L (males) plus symptom onset >2 h met our performance benchmark. A 3-h delta cut-point >35 ng/L met the performance benchmark, but poor precision means further adequately powered research is required.

RESUMO

BACKGROUND: In contrast to traditional femoral artery access, radial artery access for primary percutaneous coronary intervention (PPCI) in ST-elevation myocardial infarction (STEMI) is associated with reduced mortality and bleeding but has higher crossover rates. Therefore, factors associated with crossover warrant exploration as crossover due to technical challenges associated with the radial route may be mitigated. OBJECTIVE: The objective of this study was to identify predictors of radial access failure or crossover to femoral access in PPCI. METHODS: A systematic review and meta-analysis was undertaken according to the Joanna Briggs Institute Systematic Reviews Checklist with searches conducted in Medline, EMBASE, CINAHL, and SCOPUS databases. Inclusion criteria for this study included patients with STEMI; PPCI; and primary research identifying predictors of radial access failures and/or crossovers, published in English, and after 2010. This study was registered with PROSPERO (CRD42020167122). Statistical analysis was performed using IBM SPSS Statistics for Windows version 26.0 (IBM Corp, Armonk, NY) and RevMan version 5.4 (Cochrane Collaboration, London, United Kingdom) with meta-analysis conducted by using the DerSimonian and Laird random-effects method. The National Heart, Lung, and Blood Institute Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies was utilised for quality and risk of bias assessment, with EndNote software used for citations. RESULTS: Eight observational studies met inclusion criteria, comprising 12,621 patients. Risk of bias of these studies was assessed using the National Heart, Lung, and Blood Institute Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies. The mean age was 61.2 ± 12.0 years, and 75.3% were male. Crossover from transradial to transfemoral artery occurred in 529 (4.2%) patients. Reasons for radial access failure included failed puncture (35.3%), peripheral occlusion or tortuosity (24.5%), and radial artery spasm (20.1%). Predictors of crossover included older age (odds ratio [OR], 1.95; 95% confidence interval [CI], 1.44-2.65; p < 0.001), female sex (OR, 2.10; 95% Cl, 1.58-2.80; p < 0.001), weight ≤65 kg (OR, 2.95; 95% CI, 1.95-4.46; p < 0.001), and previous percutaneous coronary intervention (OR, 2.80; 95% Cl, 1.74-4.52; p < 0.001). CONCLUSION: Older age, female sex, weight ≤65 kg, and previous percutaneous coronary intervention were predictors of crossover or failure from the radial to femoral artery. As these predictors are known to be associated with high bleeding and mortality, they should not preclude attempting a radial-first approach in all patients with STEMI. However, as these results were unadjusted, this study warrants further research to thoroughly investigate predictors of radial artery crossover.

RESUMO

OBJECTIVE: To estimate the total economic impact of peripheral intravenous catheter (PIVC) or cannula insertion and use in adult Australian EDs, including those cannulas that remain unused for therapeutic purposes. METHODS: Searches on Australian government websites were conducted to find rates of insertion, complications and cost of cannula; following this, gaps in national data sets were filled with MEDLINE and PubMed searches to estimate the total cost of cannula use in Australian EDs. Once the data were collected, totals were combined to establish an estimated cost for the listed categories. RESULTS: The estimated cost of cannulation in Australia may be up to A$594 million per year, including the cost of insertion (equipment and staff), cost of complications such as Staphylococcus aureus bacteraemia and phlebitis, and patient-centred costs (lost patient productivity, infiltration, occlusion and dislodgement). Approximately A$305.9 million is attributed to unused cannulas and approximately 11 790 days of clinician time is spent annually inserting cannula that remains idle. CONCLUSION: The figures developed in the present study represent an important educational opportunity to encourage thoughtful consideration of all interventions, no matter how small. ED cannula insertion represents a large economic and health cost to Australia's health system, many of which remain unused. There are no national data sets that record complications associated with PIVCs and we highlight the urgent need for improved data.

RESUMO

BACKGROUND: How nursing students perceive themselves as potential nurses in the future is defined as their nursing professional identity. Many undergraduate nursing students present positive attitudes regarding the use of social media. However, the influence of social media usage by undergraduate nursing students on the development of their professional identity is yet to be determined. OBJECTIVE: To determine the relationship between social media usage by undergraduate nursing students and the development of their professional identity. DESIGN: Descriptive, correlational, cross-sectional study. SETTING(S): Two universities in western Saudi Arabia. PARTICIPANTS: Undergraduate nursing students who used social media. METHODS: An online questionnaire was designed, and its contents were validated. It was then distributed via a Qualtrics link to students' email addresses and via social media between 4th September 2019 and 28th October 2019. Descriptive analysis including frequencies, percentages, medians, and interquartile ranges were reported. Additionally, a number of non-parametric tests were conducted to investigate the relationships in question. RESULTS: In total, 484 questionnaires were included in the analysis. The participants who used social media for educational (p = 0.004), or for professional purposes (p = 0.015) had high scores on the PI scale. The professional identity scores were also positively associated among the participants who followed nurses (p < 0.001), shared their nursing experiences (p < 0.001), and acted as societal educators about the nursing profession (p < 0.001) on social media platforms. CONCLUSIONS: Engagement with social media positively influenced undergraduate nursing students in the development of their professional identity. However, it is notable that the pedagogy of nursing education has been slow to adopt social media into nursing curricula. Nursing students require guidance in terms of how to use social media for their professional development.

RESUMO

BACKGROUND: Radial access for primary percutaneous coronary intervention (PCI) in ST elevation myocardial infarction (STEMI) is associated with reduced mortality and bleeding, when compared to femoral access. However, radial access failure may be associated with an increased door-to-device (DTD) time. AIMS: To identify predictors of radial access failure requiring crossover to femoral artery access during primary PCI. METHODS: From 2013 to 2020, 2,256 consecutive patients treated for PPCI at a single tertiary hospital were prospectively recruited into the Victorian Cardiac Outcomes Registry and followed for 30 days. Multivariable logistic regression was used to identify independent predictors of radial to femoral access crossover. RESULTS: From 2,256 STEMI patients, primary radial access was used in 1,778 (78.8%), with 171 (9.6%) experiencing radial-to-femoral crossover. Patients with failed versus successful radial access experienced longer DTD times (67 mins, interquartile range [IQR] 46-99 vs 54 mins [IQR 39-78]; p<0.001). Independent predictors of radial-to-femoral access crossover included female sex (Adjusted Odds Ratio [AOR] 2.1, 95% Confidence Interval [CI] 1.4-3.0; p<0.001) and baseline hypertension (AOR 1.5, 95% CI 1.1-2.1; p=0.018). CONCLUSION: In a real-world STEMI registry, almost 1 in 10 patients experienced access crossover from the radial to femoral artery which resulted in longer DTD times. Independent predictors of radial access failure included female sex and baseline hypertension. Knowing which patient characteristics are associated with increased risk of radial artery failure enables catheter laboratory staff to ensure equipment is readily available to maximise successful primary PCI are available.

RESUMO

Whilst research has largely focused on the recognition of emotional items, emotion may be a more subtle part of our surroundings and conveyed by context rather than by items. Using ERPs, we investigated which effects an arousing context during encoding may have for item-context binding and subsequent familiarity-based and recollection-based item-memory. It has been suggested that arousal could facilitate item-context bindings and by this enhance the contribution of recollection to subsequent memory judgements. Alternatively, arousal could shift attention onto central features of a scene and by this foster unitisation during encoding. This could boost the contribution of familiarity to remembering. Participants learnt neutral objects paired with ecologically highly valid emotional faces whose names later served as neutral cues during an immediate and delayed test phase. Participants identified objects faster when they had originally been studied together with emotional context faces. Items with both neutral and emotional context elicited an early frontal ERP old/new difference (200-400 ms). Neither the neurophysiological correlate for familiarity nor recollection were specific to emotionality. For the ERP correlate of recollection, we found an interaction between stimulus type and day, suggesting that this measure decreased to a larger extend on Day 2 compared with Day 1. However, we did not find direct evidence for delayed forgetting of items encoded in emotional contexts at Day 2. Emotion at encoding might make retrieval of items with emotional context more readily accessible, but we found no significant evidence that emotional context either facilitated familiarity-based or recollection-based item-memory after a delay of 24 h.

RESUMO

BACKGROUND: High-sensitivity cardiac troponin I (hs-cTnI) assays promise high diagnostic accuracy for myocardial infarction (MI). In an ED where conventional cTnI was in use, we evaluated an assessment pathway using the new Access hsTnI assay. METHODS: This retrospective analysis recruited ED patients with suspected MI between June and September 2019. All patients received routine care with a conventional cTnI assay (AccuTnI +3: limit of detection (LoD) 10 ng/L, 99th centile upper reference limit (URL) 40 ng/L, abnormal elevation cut-point 80 ng/L). Arrival, then 90-minute or 360-minute cTnI levels for low and non-low risk patients, respectively (ED Assessment of Chest pain score) guided diagnosis and disposition which was at treating physician discretion. The same patients had arrival and 90-minute or 180-minute samples drawn for hs-cTnI levels (Access hsTnI: LoD 2 ng/L, 99th centile URL 10 ng/L (females) and 20 ng/L (males); abnormal elevation above the URL and delta >30%). Treating physicians were blinded to the hs-cTnI results. Using the hs-cTnI values, investigators retrospectively assigned likely diagnosis, disposition and likelihood of a 30-day major adverse cardiac event (MACE). Admission was recommended for significantly rising hs-cTnI elevations. The primary objective was to demonstrate an acceptable unexpected 30-day post-discharge MACE rate of <1%. cTnI elevation rates, diagnostic outcomes and ED disposition were also compared between pathways. RESULTS: For the 935 patients, unexpected 30-day post-discharge MACE rates were 0/935 (0%, 95% CI 0% to 0.4%) with the conventional or novel pathway. For the high-sensitivity and conventional assays, respectively, abnormal elevation rates were 29% (95% CI 26% to 32%) and 19% (95% CI 17% to 22%), for MI were 9% (95% CI 8% to 11%) and 8% (95% CI 6% to 10%), and for hospital admission were 42% (95% CI 39% to 45%) and 43% (95% CI 40% to 47%). CONCLUSION: The novel pathway using the Access hsTnI assay has an acceptably low 30-day MACE rate.

RESUMO

BACKGROUND: With the increasing complexity of procedures being performed in the cardiac catheterisation laboratory, the multidisciplinary team has the challenge of providing safe care to patients who present with a multitude of healthcare needs. Although the use of a surgical safety checklist has become standard practice in operating theatres worldwide, the use of a pre-procedure checklist has not been routinely adopted into interventional cardiology. OBJECTIVE: The aim of this study was to design and evaluate a pre-procedure checklist specific to the cardiac catheterisation laboratory. METHOD: A descriptive, exploratory design was used to develop a specifically designed pre-procedure checklist for use in the cardiac catheterisation laboratory in a private hospital in Melbourne, Australia. The pre-procedure checklist was developed by exploring the multidisciplinary team's opinion regarding the organisation's previous surgical pre-procedure checklist through a pre-implementation survey and focus groups. Following an expert review, and implementation of the proposed pre-procedure checklist, a post-implementation survey was completed. RESULTS: Thirty-five (70%) cardiac catheterisation laboratory healthcare professionals completed the pre-implementation survey, with 31 (62%) completing the post-implementation survey. Ninety-one per cent of participants agreed that important clinical information required for interventional procedures was not documented on the previous surgical checklist. A specific checklist was developed from the results of the survey and six focus groups (N = 25) and implemented in the cardiac catheterisation laboratory. In the post-implementation survey, participants identified that the cardiac catheterisation laboratory specific pre-procedure checklist included all relevant clinical information and improved documentation of patient information. CONCLUSION: The development of a specific cardiac catheterisation laboratory pre-procedure checklist has led to an improved transfer of pertinent clinical information required prior to procedures being performed in the unit. The outcome of this study has implications for other cardiac catheterisation laboratories with the potential to standardise practice within interventional cardiology practice and improve patient safety outcomes.

RESUMO

Women have generally worse outcomes after myocardial infarction (MI) compared to men. The reasons for these disparities are multifactorial. At the beginning is the notion-widespread in the community and health care providers-that women are at low risk for MI. This can impact on primary prevention of cardiovascular disease in women, with lower use of preventative therapies and lifestyle counselling. It can also lead to delays in presentation in the event of an acute MI, both at the patient and health care provider level. This is of particular concern in the case of ST elevation MI (STEMI), where "time is muscle". Even after first medical contact, women with acute MI experience delays to diagnosis with less timely reperfusion and percutaneous coronary intervention (PCI). Compared to men, women are less likely to undergo invasive diagnostic testing or PCI. After being diagnosed with a STEMI, women receive less guideline-directed medical therapy and potent antiplatelets than men. The consequences of these discrepancies are significant-with higher mortality, major cardiovascular events and bleeding after MI in women compared to men. We review the sex disparities in pathophysiology, risk factors, presentation, diagnosis, treatment, and outcomes for acute MI, to answer the question: are they due to biology or bias, or both?
