Background. Previous studies showed that there are gender disparities in various respects of acute myocardial infarction (AMI), including risk factors, symptoms, and outcomes. However, few of them noticed the gender disparities in patients’ decision about the management of AMI, which might also be associated with the outcome. Aims. To identify gender disparities in patients’ decisions about the management of myocardial infarction. Methods. In this cohort study, the critical time points including the time of symptom onset, visiting hospital, diagnosis of AMI, consent to coronary angiography (CAG), beginning of CAG, and balloon dilation were recorded. Medication and major adverse cardiac event (MACE) within 6 months were also recorded. Results. Female patients took more time from symptom onset to visiting hospital (P=0.001), from diagnosis of AMI to consent to CAG (P
