Abstract:Objective To analyze the risk factors of contrast induced nephropathy (CIN) after percutaneous coronary intervention (PCI), and to analyze the diagnostic value of serum soluble Klotho protein for CIN. Methods A retrospective analysis of the clinical data of 143 patients undergoing PCI surgery at Suzhou Integrated Traditional Chinese and Western Medicine Hospital from May 2017 to June 2019. According to whether CIN occurred after operation, 143 patients were divided into CIN group (27 cases) and non-CIN group (116 cases). Logistic regression was used to analyze the risk factors for CIN, and the receiver operating curve (ROC) was used to evaluate the value of Klotho protein in the diagnosis of CIN. Results The incidence of CIN after PCI was 18.89%. CIN combination and diabetes ratio, systolic blood pressure, fasting blood glucose (FBG), serum creatinine (Scr), uric acid (UA), cystatin C (CysC), high sensitivity C-reactive protein (CRP), homocysteine (Hcy) were higher than the non-CIN group (P < 0.05). The estimated glomerular tiltration rate (eGFR) and Klotho protein levels were lower than those in the non-CIN group (P < 0.05). Logistic regression analysis showed that Scr (OR = 1.017), eGFR (OR = 3.443) and Klotho protein (OR = 2.855) were risk factors for CIN (P < 0.05). Pearson analysis showed that Klotho protein was negatively correlated with Scr (r = -0.32, P < 0.05), and positively correlated with eGFR (r = 0.45, P < 0.05). The area under the curve of Klotho protein in the diagnosis of CIN was 0.823, the sensitivity was 87.2%, the specificity was 74.5%, and the Youden index was 0.617. Conclusion Scr, eGFR and Klotho protein are the risk factors for CIN, and Klotho protein has good diagnostic value for CIN.
