Values are % (number) or median [IQR]. DTB time was available in 3146 male and 752 female STEMI patients. Symptom onset–to‐balloon time (ie, ischemic time) was calculated in 3136 male and 747 female patients with both symptom‐to‐door and DTB time available. DTB indicates door‐to‐balloon time; IQR, interquartile range; LAD, left anterior descending artery; LCx, circumflex artery; MI, myocardial infarction; NSTEMI, non–ST‐segment–elevation myocardial infarction; RCA, right coronary artery; STEMI, ST‐segment–elevation myocardial infarction.
