Values are mean±standard deviation or % (number) or median [IQR]. BMI indicates body mass index; CABG, coronary artery bypass grafting; CVD, cerebrovascular disease; eGFR, estimated glomerular filtration rate; IQR, interquartile range; MI, myocardial infarction; NSTEMI, non–ST‐segment–elevation myocardial infarction; OAC, oral anticoagulation; PCI, percutaneous coronary intervention; PVD, peripheral vascular disease; STD time, symptom‐to‐door time; STEMI, ST‐segment–elevation myocardial infarction.
