Reducing gap in pre-hospital delay between women and men presenting with ST-elevation myocardial infarction
Authors' conclusion
Over two decades, delay between symptom onset and hospital admission in STEMI decreased significantly for men and women. The decline was more pronounced in women, leading to the sex gap disappearing in the adjusted analysis for 2019.
