Abstract

Aims

This study aimed to analyse changes in pre-hospital delay over time in women and men presenting with ST-elevation myocardial infarction (STEMI) in Switzerland.

Methods and results

AMIS Plus registry data of patients admitted for STEMI between 2002 and 2019 were analysed using multivariable quantile regression including the following covariates: interaction between sex and admission year, age, diabetes, pain at presentation, myocardial infarction (MI) history, heart failure history, hypertension, and renal disease. Among the 15,350 patients included (74.5% men), the median (interquartile range) delay between 2002 and 2019 was 150 (84; 345) min for men and 180 (100; 414) min for women. The unadjusted median pre-hospital delay significantly decreased over time for both sexes but the decreasing trend was stronger for women. Specifically, the unadjusted sex differences in delay decreased from 60 min in 2002 (P = 0.0042) to 40.5 min in 2019 (P = 0.165). The multivariable model revealed a significant interaction between sex and admission year (P = 0.038) indicating that the decrease in delay was stronger for women (−3.3 min per year) than for men (−1.6 min per year) even after adjustment. The adjusted difference between men and women decreased from 26.93 min in 2002 to −1.97 min for women in 2019.

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.
