Key result
Female sex was associated with a higher likelihood of symptom-to-presentation time >90 minutes compared to men among patients with STEMI (72% vs 54%; OR 2.46, 95% CI 1.10-5.60, P=0.03).
Why the study?
Previous studies showed longer delays from symptom onset to hospital presentation in women than men with acute myocardial infarction, but reasons for these delays remained incompletely understood.
Observational (n=218)
Yes
Odds Ratio: 2.46 (95% CI 1.1–5.6)
Absolute Event Rate: 72% vs 54%
p-value: p=0.03
Women with STEMI experience longer pre-hospital delays than men, largely driven by atypical symptoms and a lack of recognition of myocardial infarction.

May inform sex-specific STEMI awareness campaigns; leaves open whether interventions reduce presentation delays.
A 2022 study conducted an observational in ST-Segment Elevation Myocardial Infarction (STEMI) (n=218). Female sex vs. Male sex was evaluated on Symptom onset to hospital presentation (S2P) time >90 minutes (OR 2.46, 95% CI 1.10-5.60, p=0.03). Female sex was associated with a higher likelihood of symptom-to-presentation time >90 minutes compared to men among patients with STEMI (72% vs 54%; OR 2.46, 95% CI 1.10-5.60, P=0.03).
