In-hospital 'CODE STEMI' improves door-to-balloon time in patients undergoing primary percutaneous coronary intervention.

Objective: Reducing time to reperfusion for ST-segment elevation myocardial infarction (STEMI) is essential in improving outcomes. Consequently, numerous strategies have been employed to reduce median door-to-balloon time (DTBT).

Methods: CODE STEMI is an ED physician-activated STEMI notification system.
