AbstractThis paper discusses a possible weakness of the HEART Pathway specific to patients identified as high risk, requiring admission for inpatient risk stratification. Emergency Department (ED) crowding is at an all-time high and the possibility that many of these patients will board in the ED for a period of time before they are transported to an inpatient ward is becoming more likely. Given troponins peak at 6 h after the initial cardiac injury, it is plausible an initial troponin could still remain negative upon arrival. Extending the HEART Pathway to include a 3-hour delta troponin for admitted patients boarded in the emergency department may help alert the patient's inpatient team of those requiring more aggressive evaluations or more timely interventions. The case discussed herein highlights the course of a patient who was admitted to a medicine floor for chest pain along the HEART Pathway. After remaining in the ED for 3 h following admission a second troponin was drawn that resulted in the diagnosis of a non-ST segment myocardial infarction. The patient then received further management in the ED and a change in admission to the Cardiac Care Unit instead of the medicine floor. The patient ultimately received a Coronary Artery Bypass Graft during admission. If the patient had not had the second troponin while in the ED this care would have been delayed.Published by Elsevier Inc.
