Cardiac troponins (cTn) are structural components of myocardial cells and are expressed almost exclusively in the heart. Elevated cTn levels indicate myocardial cell damage/death but not reflect the underlying etiology. The third universal definition of myocardial infarction (MI) differentiates MI into various types. Type 1 (T1MI) is due to plaque rupture with thrombus, while type 2 (T2MI) is a result of a supply:demand mismatch. Non-MI cTn elevations are also common. We determined the causes of elevated cTn in a tertiary care emergency department (ED) and the associated in-hospital mortality. ⋯ Of all ED patients with elevated cTn, ~75% have a non-T1MI. The mortality of patients with non-T1MI is similar to the mortality in patients with T1MI.

In 2012 the Accreditation Council for Graduate Medical Education and the American Board of Emergency Medicine released the emergency medicine milestones. The Patient Care 12 (PC12) subcompetency delineates staged and progressive accomplishment in emergency ultrasound. ⋯ A multiorganizational task force was formed between the American College of Emergency Physicians Ultrasound Section, the Council of Emergency Medicine Residency Directors, and the Academy of Emergency Ultrasound of the Society for Academic Emergency Medicine. Representatives from each organization created this consensus document and revision.
