The Role of Pan-Immune-Inflammation Value in Predicting Contrast-Induced Nephropathy Development in Patients Undergoing Percutaneous Coronary Intervention Due to NSTEMI

Contrast-induced nephropathy (CIN), which can develop after procedures involving contrast agents, is a significant cause of patient morbidity and mortality. This study aims to investigate the role of pre-procedural pan-immune-inflammation value (PIV) in predicting CIN development in patients undergoing percutaneous coronary intervention (PCI) due to non-ST segment elevation myocardial infarction (NSTEMI). A total of 1006 NSTEMI patients were included in the study. CIN was defined as an increase of at least 0.5 mg/dl or 25% in serum baseline creatinine level 72 h after the procedure. Patients were divided into two groups: those with and without CIN. NSTEMI patients who developed CIN, glucose level ( P = .01), platelet count ( P < .01), monocyte count ( P < .001), neutrophil-to-lymphocyte ratio (NLR) ( P < .001), systemic immune inflammation index (SII) score ( P < .001), and PIV ( P < .001) were higher compared with those without CIN. In the multivariate analysis of all these parameters, the Odds ratios of PIV and SII were similar and slightly lower than NLR. Receiver operating characteristic curve analysis (ROC) showed a PIV cut-off value of 448.43 with a sensitivity of 83.1% and a specificity of 72.8% in patients with CIN. Our study demonstrated an independent relationship between PIV at admission and CIN development in NSTEMI patients.
