CI-AKI: contrast-induced acute kidney injury; HR: heart rate; DBP: diastolic blood pressure; CKD: chronic kidney disease; SCr: serum creatinine; eGFR: estimate glomerular filtration rate; LVEF: left ventricular ejection fraction; AMI: acute myocardial infarction; ACEI: angiotensin-converting enzymes inhibitors; ARB: angiotensin-receptor blockers; PCI: percutaneous coronary intervention; and IABP: intra-aortic balloon pump.
