Sex differences in the intention and decision to use emergency medical services for acute coronary syndrome in Australia: a retrospective study.

Background: Sex-based disparities in acute coronary syndrome (ACS) presentations exist and women often have worse outcomes after an ACS event. Calling the emergency medical services (EMS) initiates prehospital diagnosis and treatment and reduces in-hospital time to treatment. This study aims to identify factors affecting the intention to call EMS and EMS usage in Australian women and men.
