Emergency and critical care physicians frequently encounter patients presenting with dyspnea and normal left ventricular systolic function who may benefit from early diastolic evaluation to determine acute patient management. The current American Society of Echocardiography Guidelines approach to diastolic evaluation is often impractical for point of care ultrasound (POCUS) evaluation, and few studies have evaluated the potential use of a simplified approach. This article reviews the literature on the use of a simplified diastolic evaluation to assist in determining acute patient management.

Article Synopsis
  • CT scans without IV contrast are frequently used to check for vertebral injuries.
  • When a fracture is close to blood vessels, CT angiography scans are recommended.
  • Using CT angiography can help identify potential vascular injuries that might not be visible with standard CT scans.

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.

A 34-year-old man with recent treatment and resolution of community-acquired pneumonia presents to the emergency department with protracted fever, rash, and sore throat. Sustained fever and greater than two-fold increase in leukocytosis despite appropriate antibiotic therapy prompted hospital admission for infectious disease and rheumatologic evaluations which ultimately revealed adult-onset Still's disease, a rare autoinflammatory disorder with potentially life-threatening complications.

Hematuria is common; whether gross or microscopic, it is incumbent on emergency providers to consider life-threatening and benign processes when evaluating these patients. Most workup is driven by a focused history and physical, including laboratory studies and diagnostic imaging. The cause originates in the genitourinary tract and, as long as the patient remains stable, they can be discharged with close outpatient follow-up.

Background: Spontaneous spinal and intracranial subdural hematomas are rarely reported, especially occurring simultaneously. Anticoagulation use has been associated with spontaneous hemorrhages. Prompt diagnosis is required to prevent permanent neurological sequelae.

A 48-year-old male with a history of intravenous (IV) drug use presented to the emergency department (ED) for an area of mild pain and erythema on his chest. He was then triaged to the urgent care, or fast track, area of the ED. He was well appearing with normal lab findings and vital signs, but his workup revealed mediastinitis with osteomyelitis of the manubrium and clavicles, a surgical emergency.

Cardiogenic shock (CS) is a physiologic state in which cardiac pump function is inadequate to perfuse the tissues. If CS is not rapidly recognized and treated, tissue hypoperfusion can quickly lead to organ dysfunction and patient death. Evaluation of patients with suspected CS should include an electrocardiogram, chest radiograph, laboratory studies, and bedside echocardiogram.

Less than half of patients with a chest pain history indicative of acute coronary syndrome have a diagnostic electrocardiogram (ECG) on initial presentation to the emergency department. The physician must dissect the ECG for elusive, but perilous, characteristics that are often missed by machine analysis. ST depression is interpreted and often suggestive of ischemia; however, when exclusive to leads V1-V3 with concomitant tall R waves and upright T waves, a posterior infarction should first and foremost be suspected.

Cardiac dysfunction is a common complication of sepsis in individuals with preexisting coronary disease and portends a poor prognosis when progressing to ischemic cardiogenic shock. In this setting, maximal medical therapy in isolation is often inadequate to maintain cardiac output for patients who are poor candidates for immediate revascularization. Furthermore, the use of vasopressors and inotropes increases myocardial demand and may lead to further injury.

Pregnancy is a complex and dynamic physiologic state, in which the needs of the mother and fetus must achieve a fine balance with one another. Some of the most dreaded and deadly complications that can arise during this period affect the cardiovascular system are hypertensive emergencies (including preeclampsia and eclampsia), acute coronary syndrome, peripartum cardiomyopathy, dysrhythmias, dissection, thromboembolism, and cardiac arrest. This review provides emergency physicians, obstetricians, intensivists, and other health care providers with the most recent information on the diagnosis and management of these deadly cardiovascular complications of pregnancy.

Article Synopsis
  • Coronary artery disease (CAD) is the leading cause of death for both men and women, but women develop it later and experience worse outcomes than men of the same age.
  • A consensus group from the 2014 Academic Emergency Medicine conference identified sex- and gender-specific gaps in emergency care for cardiac ischemia, engaging a diverse range of professionals and stakeholders.
  • The group prioritized five key themes and 30 research questions that focus on the need for better understanding and addressing sex-specific factors in CAD risk, diagnosis, pathophysiology, treatment, and prognosis.

Hyperthyroidism and thyrotoxicosis are hypermetabolic conditions that cause significant morbidity and mortality. The diagnosis can be difficult because symptoms can mimic many other disease states leading to inaccurate or untimely diagnoses and management. Thyroid storm is the most severe form of thyrotoxicosis, hallmarked by altered sensorium, and, if untreated, is associated with significant mortality.

Care of the patient with return of spontaneous circulation following sudden cardiac death is complex and challenging. A systematic and comprehensive approach can increase the chances of meaningful recovery of the postarrest patient. This article focuses on a systematic approach to the postarrest patient, which includes optimizing oxygenation and ventilation, maintaining adequate perfusion pressure, monitoring oxygen delivery, initiating and maintaining therapeutic hypothermia, and identifying patients appropriate for emergent cardiac catheterization.
