SBP: systolic blood pressure; HR: heart rate; MI: myocardial infarction; STEMI: ST-elevation myocardial infarction; PG: plasma glucose; WBC: white blood cell; TIMI: thrombolysis in myocardial infarction; PCI: percutaneous coronary intervention; CK: creatine phosphokinase. P < 0.05 versus low K; P < 0.05 versus mid K.
