STEMI cohort included here was only those in whom DTB time was calculated (patients who presented within 12 hours without interhospital transfer). CABG indicates coronary artery bypass grafting; CVD, cerebrovascular disease; DTB time, door‐to‐balloon time; eGFR, estimated glomerular filtration rate; LVEF, left ventricular ejection fraction; MI, myocardial infarction; NSTEMI, non–ST‐segment–elevation myocardial infarction; OR, odds ratio; PCI, percutaneous coronary intervention; PVD, peripheral vascular disease; STD time, symptom‐to‐door time; STEMI, ST‐segment–elevation myocardial infarction.
