Abstract:Objective To explore the predictive value of renal artery resistance index(RRI)on contrast-induced acute kidney injury(CI-AKI)in patients with type 2 diabetes mellitus(T2DM)after percutaneous coronary intervention(PCI).Methods A total of 100 cases of T2DM patients who underwent PCI treatment in Pingxiang People′s Hospital from January 2020 to September 2020 were selected as the research objects.According to CI-AKI diagnostic criteria,they were divided into a CI-AKI group(n=30)and a non-CI-AKI group(n=70).The baseline data,serum creatinine(Scr)levels and RRI between the two groups were compared,and the influencing factors of CI-AKI in patients with T2DM after PCI were analyzed,the receiver operating characteristic(ROC)curve was drawn to judge the value of contrast agent dose,peak systolic velocity(PSV)of renal artery,end diastolic velocity(EDV),Scr levels and RRI in the detection of CI-AKI.Results The results of univariate analysis showed that there were statistical significant differences in compared contrast dose,PSV and EDV between CI-AKI group and non CI-AKI group(P<0.05);the levels of Scr at 24 h and 48 h after operation and RRI at 24 h after operation in CI-AKI group were higher than those in non CI-AKI group(P<0.05);the results of Logistic multivariate analysis showed that the dose of contrast medium(β=0.048,OR=1.050,95%CI=1.031-1.069),PSV(β=-0.301,OR=0.832,95%CI=0.803-0.982),EDV(β=-0.356,OR=0.625,95%CI=0.531-0.878),Scr level(β=0.063,OR=1.065,95%CI=1.042-1.090),RRI(β=2.999,OR=20.063,95%CI=1.204-334.228)were the related influenccing factors of CI-AKI in T2DM patients after PCI(P<0.05).ROC curve was drawn,and the results showed that contrast agent dose,PSV,EDV,Scr,RRI detected the area under the curve(AUC)of patients with T2DM after PCI were 0.880,0.928,0.971,0.878 and 0.925,respectively,the sensitivity of each index were 97.0%,97.1%,95.7%,98.6% and 97.2% respectively,all higher than 90.0%,but the specificity of RRI was the highest(96.7%),therefore,the predictive value of RRI in detection of CI-AKI was higher.Conclusion Higher dose of contrast agent,PSV,EDV,Scr level and RRI are the influencing factors for the occurrence of CI-AKI after PCI in T2DM patients,among them,RRI can better predict CI-AKI.Early detection of RRI has important value for the early diagnosis and clinical diagnosis and treatment of CI-AKI after PCI treatment for T2DM.
