ABSTRACT Background Contrast-induced nephropathy is one of the main causes of hospital-acquired acute renal failure. The Mehran risk score and the contrast medium volume used/creatinine clearance ratio could help identifying patients at higher risk of developing contrast-induced nephropathy. This study aimed to compare these two scores. Methods A retrospective, single-center observational study including hospitalized patients with baseline creatinine >1.3mg/dL, under observation for at least 48 hours after coronary computed tomography angiography and/or percutaneous coronary intervention. Mehran risk score and contrast […]
