Comparison of demographic and clinical characteristics based on admission eGFR and AKI development.

<p>eGFR, 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, systolic blood pressure; HR, heart rate. Continuous variables are presented as median values (with interquartile ranges) and were analyzed by the Kruskal-Wallis test followed by Dunn's post-test. Categorical variables are presented as percentages and were analyzed by χ² statistics with Bonferroni correction for post-test multiple comparisons.</p>*<p>p<0.001,</p>†<p>p = 0.009,</p>**<p>p = 0.013, admission eGFR≥60, with AKI versus without AKI,</p>‡<p>(beats/min).
