Mehran Risk Score Is Still Valuable for Prediction of Contrast Nephropathy in Patients With Acute Coronary Syndrome

Abstract

We read the article entitled “Systemic immune inflammation index: a novel predictor of contrast-induced nephropathy in patients with non-ST segment elevation myocardial infarction” by Kelesoglu et al with interest. The authors showed that the systemic immune inflammation (SII) index, a surrogate inflammatory marker, is a predictor of contrast nephropathy in patients with non-ST segment elevation myocardial infarction (NSTEMI). The SII index showed significant impact, especially in malignancy prognosis. Recently, Erdogan et al showed that the SII is an independent predictor of functionally significant coronary stenosis detected by fractional flow reserve in chronic coronary syndrome patients. The Mehran risk score is useful for the prediction of contrast-induced nephropathy. Did the authors calculate the Mehran risk score before intervention in patients with NSTEMI? If calculation is possible, is there any correlation after regression analysis between the SII and Mehran risk scores? ORCID iD
