a-eGFR, admission estimated glomerular filtration rate (mL/min/1.73 m2); PCI, percutaneous coronary intervention; CABG, coronary artery bypass graft; CAD, coronary artery disease; AMI, acute myocardial infarction; ACEI, angiotensin-converting enzyme inhibitors; ARB, angiotensin II receptor blockers; STEMI, ST elevation myocardial infarction; aSBP, admission systolic blood pressure; aHR, admission heart rate. Continuous variables are presented as median values (with interquartile ranges). Categorical variables are presented as percentages.
n = 821 for the total cohort, n = 444 for a-eGFR≥60 mL/min/1.73 m2, and n = 377 for a-eGFR<60 mL/min/1.73 m2.
n = 827 for the total cohort; n = 380 for a-eGFR<60 mL/min/1.73 m2.
n = 416 (STEMI patients).
