Impact of atypical presenting symptoms on door-to-balloon time and mortality outcomes in ST-segment elevation myocardial infarction.

ABSTRACT:

Background

The impact of atypical symptom presentation in ST-segment elevation myocardial infarction (STEMI) on treatment timeliness and long-term outcomes remains insufficiently characterized. This study aimed to examine the association between symptom presentation and delays in door-to-balloon (DTB) time components and short- and long-term mortality, and to identify triage characteristics independently associated with atypical STEMI presentation.

Methods

We conducted a retrospective cohort study of STEMI patients undergoing primary percutaneous coronary intervention at a tertiary hospital in Taiwan between 2013 and 2022. Symptom presentation was classified as typical or atypical based on emergency department triage records. Primary outcomes included delays in DTB component
