Positive predictive value of an elevated cardiac troponin for type I myocardial infarction in ED patients based on the chief complaint

Chest pain evaluation in the emergency department

Chest pain is a common complaint in the emergency department. Recognition of chest pain symptoms and electrocardiographic changes consistent with acute coronary syndrome (ACS) can lead to prompt initiation of goal-directed therapy. Cardiac troponin testing confirms the diagnosis of acute myocardial infarction, but does not reveal the mechanism of injury. When patients with chest pain rule out for ACS the use of advanced, noninvasive testing has not been found to be associated with better patient outcomes.
