    Contrast-induced nephropathy (CIN) has become one of the most important causes of in-hospital acute renal failure with the increasing use of contrast-mediated imaging tools. This significantly increases the morbidity and mortality of the affected subjects and causes a financial burden on the health system. In this context, prediction of CIN is important and some risk scores have been developed to predict CIN. The most frequently used and popular among these is the Mehran Score (MS), which is based on a number of hemodynamic and metabolic parameters. The Intermountain Risk Score (IMRS) is a recently developed risk score that highly predicts short-term mortality based on common laboratory parameters, and many parameters of this risk score have been found to be closely associated with CIN. In this context, we aimed to compare MS and IMRS in terms of CIN and short-term mortality estimation. The study included 931 patients who underwent percutaneous coronary intervention. CIN developed in 21.5% of patients. Both MS and IMRS independently predicted CIN. In receiver operating characteristic analysis, IMRS was found to be non-inferior to MS in predicting CIN and IMRS was superior to MS in predicting short-term mortality. IMRS and MS were independently associated with short-term mortality.
