Diagnosis and management of arrhythmogenic right ventricular cardiomyopathy.

Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a genetic disorder of the myocardium that can lead to ventricular arrhythmia and sudden cardiac death. The condition has been identified as a significant cause of arrhythmic death among young people and athletes, therefore, early recognition of the disease by emergency clinicians is critical to prevent subsequent death. The diagnosis of ARVC can be very challenging and requires a systematic approach. This publication reviews the pathophysiology, classification, clinical presentations, and appropriate approach to diagnosis and management of ARVC.

Dysrhythmias associated with COVID-19: Review and management considerations.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes coronavirus disease 2019 (COVID-19), is known to affect the cardiovascular system. Cardiac manifestations in COVID-19 can be due to direct damage to the myocardium and conduction system as well as by the disease's effect on the various organ systems. These manifestations include acute coronary syndrome, ST- segment elevations, cardiomyopathy, and dysrhythmias. Some of these dysrhythmias can be detrimental to the patient. Therefore, it is important for the emergency physician to be aware of the different arrhythmias associated with COVID-19 and how to manage them. This narrative review discusses the pathophysiology underlying the various arrhythmias associated with COVID-19 and their management considerations.

High-dose nitroglycerin infusion description of safety and efficacy in sympathetic crashing acute pulmonary edema: The HI-DOSE SCAPE study.

BACKGROUND: Sympathetic crashing acute pulmonary edema (SCAPE) is a medical emergency in which severe, acute elevation in blood pressure results in acute heart failure and fluid accumulation in the lungs. Without prompt recognition and treatment, the condition often progresses rapidly to respiratory failure necessitating intubation and intensive care unit (ICU) admission. In addition to non-invasive positive pressure ventilation (NIPPV), high-dose nitroglycerin (HDN) has become a mainstay of treatment; however, an optimal dosing strategy has not been established. OBJECTIVE: The purpose of this study was to describe the characteristics and outcomes of patients who received an HDN infusion (≥ 100 µg/min) for the management of SCAPE in the Emergency Department (ED) of a large urban academic medical center. Outcomes were also analyzed to determine predictors of safety and efficacy including use of adjunct medication therapies. RESULTS: There were 67 adult patients who received HDN infusion for SCAPE from January 1, 2018 to December 31, 2018. The median (IQR) systolic blood pressure (SBP) on initiation of HDN infusion was 211 (192-233) mmHg. Patients were 63% male, 84% black, 51% had a history of heart failure (HF), and 36% had end-stage renal disease (ESRD). IV nitroglycerin (NTG) was initiated at a median (IQR) dose of 100 (100-200) mcg/min with median (IQR) peak rate in the first hour of 200 (127.5-200) mcg/min and an absolute maximum observed rate of 400 µg/min overall. 73% of patients received NIPPV, 48% sublingual (SL) or IV bolus nitroglycerin before HDN infusion, 58% loop diuretic, and 34% angiotensin-converting enzyme inhibitor (ACEI) or angiotensin II receptor blocker (ARB). Rates of ICU admission, intubation, acute kidney injury (AKI) at 48 h, and hypotension were 37%, 21%, 13%, and 4% respectively. CONCLUSION: This is the largest to date study describing the use of an HDN infusion (≥100 µg/min) strategy for the management of SCAPE. HDN infusion may be a safe alternative strategy to intermittent bolus HDN.

Can I Send This Patient With Atrial Fibrillation Home From the Emergency Department?

BACKGROUND: Atrial fibrillation (AF) is one of the most common dysrhythmias managed in the emergency department (ED) setting. Due to the variety of patient presentations and disease severity, most patients in the United States are admitted to the hospital. CLINICAL QUESTION: In patients who present with AF, is there a reliable decision tool that clinicians can use to predict the risk of adverse outcome and determine who may be appropriate for discharge? EVIDENCE REVIEW: Studies retrieved included two prospective observational cohort studies and four retrospective observational studies. These studies evaluate the use of risk decision tools in predicting adverse outcomes in patients with AF. CONCLUSION: Based on the available literature, RED-AF, AFFORD, and the AFTER (complex, modified, and pragmatic) scores demonstrate modest predictive discrimination in predicting adverse events, but further validation is recommended.

Can I Send This Syncope Patient Home From the Emergency Department?

BACKGROUND: Syncope is a common presentation to the emergency department (ED). A significant minority of these patients have potentially life-threatening pathology. Reliably identifying that patients require hospital admission for further workup and intervention is imperative. CLINICAL QUESTION: In patients who present with syncope, is there a reliable decision tool that clinicians can use to predict the risk of adverse outcome and determine who may be appropriate for discharge? EVIDENCE REVIEW: Four articles were reviewed. The first retrospective study found no difference in mortality or adverse events in patients admitted for further evaluation rather than discharged home with primary care follow-up. The next two articles examined the derivation and validation of the Canadian Syncope Risk Score (CSRS). After validation with an admission threshold score of -1, the sensitivity and specificity of the CSRS was 97.8% (95% confidence interval [CI] 93.8-99.6%) and 44.3% (95% CI 42.7-45.9%), respectively. The last article looked at the derivation of the FAINT score, a recently developed score to risk stratify syncope patients. A FAINT score of ≥ 1 (any score 1 or higher should be admitted) had a sensitivity of 96.7% (95% CI 92.9-98.8%) and specificity 22.2% (95% CI 20.7-23.8%). CONCLUSIONS: Syncope remains a difficult chief symptom to disposition from the ED. The CSRS is modestly effective at establishing a low probability of actionable disease or need for intervention. However, CSRS might not reduce unnecessary hospitalizations. The FAINT score has yet to undergo validation; however, the initial derivation study offers less diagnostic accuracy compared with the CSRS.

Emergency Medicine Interest Groups.

Emergency Medicine Interest Groups (EMIGs) serve as a bountiful resource for students interested in pursuing a career in Emergency Medicine (EM). In this article we elaborate on how medical students can get involved as members in an EMIG, discuss opportunities for leadership through these groups, detail how to make the most out of the EMIG (including a listing of important lectures, workshops/labs and opportunities for growth and advancement), provide a framework for how to institute a new EMIG when one does not exist, and discuss considerations for international EMIG groups.

Management of acute myocardial infarction during the COVID-19 pandemic: A Consensus Statement from the Society for Cardiovascular Angiography and Interventions (SCAI), the American College of Cardiology (ACC), and the American College of Emergency Physicians (ACEP).

The worldwide pandemic caused by the novel acute respiratory syndrome coronavirus 2 has resulted in a new and lethal disease termed coronavirus disease 2019 (COVID-19). Although there is an association between cardiovascular disease and COVID-19, the majority of patients who need cardiovascular care for the management of ischemic heart disease may not be infected with this novel coronavirus. The objective of this document is to provide recommendations for a systematic approach for the care of patients with an acute myocardial infarction (AMI) during the COVID-19 pandemic. There is a recognition of two major challenges in providing recommendations for AMI care in the COVID-19 era. Cardiovascular manifestations of COVID-19 are complex with patients presenting with AMI, myocarditis simulating an ST-elevation myocardial infarction (STEMI) presentation, stress cardiomyopathy, non-ischemic cardiomyopathy, coronary spasm, or nonspecific myocardial injury, and the prevalence of COVID-19 disease in the US population remains unknown with risk of asymptomatic spread. This document addresses the care of these patients focusing on (a) varied clinical presentations; (b) appropriate personal protection equipment (PPE) for health care workers; (c) the roles of the emergency department, emergency medical system, and the cardiac catheterization laboratory (CCL); and (4) regional STEMI systems of care. During the COVID-19 pandemic, primary percutaneous coronary intervention (PCI) remains the standard of care for STEMI patients at PCI-capable hospitals when it can be provided in a timely manner, with an expert team outfitted with PPE in a dedicated CCL room. A fibrinolysis-based strategy may be entertained at non-PCI-capable referral hospitals or in specific situations where primary PCI cannot be executed or is not deemed the best option.

Evaluation of Spodick's Sign and Other Electrocardiographic Findings as Indicators of STEMI and Pericarditis.

BACKGROUND: Patients with ST elevation on electrocardiogram (ECG) could have ST elevation myocardial infarction (STEMI) or pericarditis. Spodick's sign, a downsloping of the ECG baseline (the T-P segment), has been described, but not validated, as a sign of pericarditis. OBJECTIVE: This study estimates the frequency of Spodick's sign and other findings in patients diagnosed with STEMI and those with pericarditis. METHODS: In this retrospective review, we selected charts that met prospective definitions of STEMI (cases) and pericarditis (controls). We excluded patients whose ECGs lacked ST elevation. An authority on electrocardiography reviewed all ECGs, noting the presence or absence of Spodick's sign, ST depression (in leads besides V1 and aVR), PR depression, greater ST elevation in lead III than in lead II (III > II), abrupt take-off of ST segment (the RT checkmark sign), and upward or horizontal ST convexity. We quantified strength of association using odds ratio (OR) with 95% confidence interval (CI). RESULTS: One hundred and sixty-five patients met criteria for STEMI and 42 met those for pericarditis. Spodick's sign occurred in 5% of patients with STEMI (95% CI 3-10%) and 29% of patients with pericarditis (95% CI 16-45%). All other findings statistically distinguished STEMI from pericarditis, but ST depression (OR 31), III > II (OR 21), and absence of PR depression (OR 12) had the greatest OR values. CONCLUSIONS: Spodick's sign is statistically associated with pericarditis, but it is seen in 5% of patients with STEMI. Among other findings, ST depression, III > II, and absence of PR depression were the most discriminating.

Designing the Third- and Fourth-Years Clerkship Schedule.

Deciding on a specialty may be one of the most daunting parts of medical school. Accordingly, it is important for medical students to make informed decisions regarding their choice of specialty. To do so, they should start planning early by contemplating possible career choices during the first 2 years of medical school, followed by properly designing their third- and fourth-year schedules. This article provides guidance and advice to medical students on how to schedule their clinical clerkships in order to optimize their ability to decide on a field of medicine to study and, ideally, to prepare them for a career in emergency medicine.

Couples Match in Emergency Medicine.

The Match is a daunting process for everyone, but it can be exceedingly more complicated for couples. Accordingly, the Couples Match was introduced by the National Residency Match Program in 1984 and has been witnessing a steady increase in the number of participating couples over the past 30 years. The highest number of couples participating in the match, and the highest match rate among them, was recorded in 2018. In this article, we provide couples considering the Couples Match, with one or both partners planning to apply to emergency medicine, with insights on this process. Although it may initially appear to be complicated, the Couples Match enables partners to obtain postgraduate training in geographic proximity to one another. With good communication between the partners and their advisors, an exciting joint venture can unfold that is fueled by the strength of the couple.

Clerkships in Emergency Medicine.

Planning for clerkships in emergency medicine (EM) can be stressful, prolonged, and challenging. Therefore, medical students should start planning for them early. In this article, we offer guidance regarding several issues pertinent to the EM clerkship, such as the best time to schedule one (or more) during medical school, the most appropriate institution or program to schedule it, the process of selecting and applying for the clerkship, and the number of EM clerkships to consider. We will explain why an EM clerkship should be scheduled between June and October and the reason that 2 EM clerkships at different sites are sufficient for the majority of students. Additionally, we emphasize that clerkships in emergency departments associated with EM residency programs or with reputations for outstanding student teaching tend to be most beneficial. Above all, students interested in EM should attempt to leave a great impression after completing their clerkships by providing stellar patient care, demonstrating enthusiasm at all times, and maintaining professionalism. In turn, they will gain knowledge and clinical experiences that should prove valuable in their future.

Applicants with Prior Training.

Emergency medicine (EM) has its challenges, downsides, advantages, and accompanying lifestyle. Additionally, graduates of EM residency programs have abundant job opportunities. Accordingly, there is an increased interest in residency training in EM, even among residents with prior training. Transitioning from another specialty to EM can be complicated yet achievable, especially if EM is the transitioning physician's passion and career goal. Therefore, in this article, we elaborate on the transition process from another discipline to EM in light of changes in residency funding. We also explore the advantages and disadvantages of transitioning to EM with previous training in another specialty. Moreover, we expand on credit equivalencies for months already completed in another training programs, as well as the difficulties to be anticipated by transitioning physicians.

An Overview of the Allopathic Match.

The number of allopathic emergency medicine (EM) programs has been progressively increasing over the years. In 2018, allopathic EM postgraduate year-1 spots, compared with 2012, increased by around 60% to reach 2278 positions. EM is considered a competitive specialty and therefore, in this article we help guide students interested in EM through the allopathic match requirements, application process, interviews, and ranking EM programs. Additionally, we tackle the combined emergency medicine residency programs, namely the combined EM-Family Medicine (FM), EM-Anesthesiology, EM-Internal Medicine (IM), EM-IM-Critical Care Medicine, and EM-Pediatrics residency programs. Finally, we explain the increased likelihood of matching with the single graduate medical education accreditation system expected to happen in the year 2020.

Combined Residency Programs in Emergency Medicine.

There are currently 5 combined residencies in emergency medicine (EM), namely EM/pediatrics, EM/internal medicine, EM/internal medicine/critical care, EM/family medicine and EM/anesthesiology. These combined programs vary from 5-6 years in length. Like categorical programs, the decision to enter a 5- or 6-year program should be an informed and comprehensive decision. We describe the history and current status of the combined EM programs, discuss the process of applying to a combined EM program, describe the life of combined EM residents, and explore common career opportunities available to combined EM program graduates.
