Cox proportional hazards model for 30-day to 1-year mortality*.

*Estimated for patients who survived for 30 days after AMI.eGFR, estimated glomerular filtration rate (mL/min/1.73 m2); AKI, acute kidney injury; AHR, adjusted hazard ratio; CI, confidence interval.The model was adjusted for age, admission glycemia (categorized by quartiles with the first as a reference), gender (females were used as the reference), ST elevation myocardial infarction, history of diabetes, history of hypertension, prior use of angiotensin-converting enzyme inhibitors or angiotensin II receptor blockers, admission Killip class >I, admission heart rate >100 beats/min, clopidogrel use during hospitalization, diuretics use, coronary angiography during hospitalization, reinfarction, severe systolic left ventricular dysfunction and any percutaneous coronary intervention performed during hospitalization.
