Low BT group was defined as patients with a max BT 4 to 10 days after admission <37.1°C, and high BT group was defined as ≥37.1°C. Data are shown as mean±SD, median (first and third quartile), or number (%). ACE‐I indicates angiotensin‐converting enzyme inhibitor; ARB, angiotensin II receptor blocker; AUC‐CK, area under the curve of creatine kinase; BT, body temperature; eGFR, estimated glomerular filtration rate; HDL, high‐density lipoprotein; LDL, low‐density lipoprotein; MI, myocardial infarction; STEMI, ST‐segment elevation myocardial infarction; TIMI, Thrombolysis In Myocardinal Infarction.
