Abstract:
Objective:To explore the evaluations of computed tomography(CT)perfusion imaging parameters and serum complement C1q/tumor necrosis factor related protein-3(CTRP-3),low density lipoprotein cholesterol(LDL-C),matrix metalloproteinase-9(MMP-9)on hemorrhagic transformation(HT)after acute cerebral infarction(ACI).Methods:A total of 206 ACI patients who admitted to the People's Hospital of Jianyang from August 2019 to July 2022 were retrospectively selected as the study objects.The patients were divided into HT group(45 cases)and non-HT group(161 cases)according to whether occurred HT after intravenous thrombolysis.The CT perfusion imaging parameters[blood flow(BF),blood volume(BV),mean transit time(MTT),permeability surface(PS)],CTRP-3,LDL-C,MMP-9 were compared between two groups.Receiver operating characteristic(ROC)curve model was used to analyze the area under curve(AUC)values,sensitivities and specificities of CT perfusion imaging parameters,CTRP-3,LDL-C and MMP-9 in diagnosing HT.Results:The BF and BV of HT group were lower than those of non-HT group,while the MTT and PS of HT group were higher than those of non-HT group,and the differences were statistically significant(t=-5.941,t=-5.777,t=5.863,t=6.954,P<005),respectively.The CTRP-3 and LDL-C of HT group were respectively lower than those of non-HT group,while the MMP-9 of HT group was higher than that of non-HT group,with statistical significances(t=-3.788,t=-5.835,t=6.935,P<0.05).The ROC curve analysis showed that the AUC values of BF,BV,MTT,PS,CT comprehensive parameters,CTRP-3,LDL-C and MMP-9 were respectively 0.790,0.779,0.738,0.775,0.949,0.692,0.777 and 0.785(P<0.05).The sensitivities of them were respectively 88.90%,100.00%,53.30%,66.70%,100.00%,88.90%,66.70%and 78.60%.The specificities of them were respectively 64.60%,51.60%,91.30%,77.60%,81.40%,47.80%,78.90%and 75.80%.The differences of the AUC values between CT comprehensive parameters and CTRP-3,and between that and LDL-C,and between that and MMP-9 were significant(Z=6.202,Z=4.563,Z=3.704,P<0.05),respectively.Conclusion:CT perfusion imaging parameters,serum CTRP-3,LDL-C and MMP-9 levels have close correlation with HT after ACI.The monitoring of the change degrees of them is helpful to provide important references for predicting the occurrence of HT in ACI patients after thrombolytic therapy.
