Association of pre-hospital time intervals and clinical outcomes in ST-elevation myocardial infarction patients.

Study Objectives: Timely coronary reperfusion is critical for favorable outcomes after ST-elevation myocardial infarction (STEMI). A substantial proportion of the total ischemic time is patient related, occurring before first medical contact (FMC). We aimed to expand the limited current understanding of the associations between prehospital intervals and clinical outcomes.
