Abstract

Strong inflammatory indicators such as C-reactive protein (CRP), high-sensitivity CRP (hsCRP), and hematological indices, including platelet to lymphocyte ratio (PLR), neutrophil to lymphocyte ratio (NLR), hematocrit (HCT), and red blood cell distribution width (RDW), may be related with contrast-induced nephropathy (CIN). Our meta-analysis aimed at exploring the relationship between these indicators and CIN incidence among patients undergoing coronary intervention. Clinical studies were retrieved from the electronic databases of PubMed, EMBASE, Google Scholar, Clinical Trials, and Science Direct from their inception to June 3, 2020. Meta-analysis was performed on pooled eligible studies. Finally, 26 studies involving 29 454 patients were included. Pooled analysis revealed that patients with higher CRP (odds ratio [OR] = 1.06, 95% CI: 1.01-1.12, P = .02), hsCRP (OR = 1.03, 95% CI: 1.01-1.06, P = .004), NLR (OR = 1.11, 95% CI: 1.01-1.20, P = .02), RDW (OR = 1.35, 95% CI: 1.19-1.53, P < .001), and lower HCT (OR = 0.94, 95% CI: 0.92-0.97, P = .003) all exhibited significantly higher CIN rates, but there was no significant association between PLR and CIN risk (OR = 1.12, 95% CI: 0.99-1.26, P = .07). Pre-angiography CRP/hsCRP and some hematological indices are associated with CIN.
