Abstract

Background: Acute coronary syndrome (ACS) refers to a spectrum of clinical
presentations ranging from those for ST-segment elevation myocardial infarction
(STEMI) to presentations found in non–ST-segment elevation myocardial infarction
(NSTEMI) or in unstable angina. Contrast-induced nephropathy (CIN) is defined as the
impairment of renal function-measured as either a 25% increase in serum creatinine
(SCr) from baseline or a 0.5 mg/dL (44 μmol/L) increase in absolute SCr value—within
48-72 hours after intravenous contrast administration.
Objective: To evaluate blood urea nitrogen to left ventricular ejection ratio and TIMI risk
index as predictors for occurrence of CIN in patients with acute coronary syndrome who
underwent PCI.
