The objective was to study patients' interpretations, thoughts, and actions after symptom onset in acute coronary syndrome (ACS) in total and in relation to gender, age, history of coronary artery disease, type of syndrome, and residential area and its influence on prehospital delay. ⋯ Interpreting symptoms as cardiac in origin and approaching someone after symptom onset were major reasons for a shorter prehospital delay in ACS.
