Abstract:
Objective To explore the value of coronary CT angiography(CCTA)combined with serum in-terleukin(IL)-12p70,protein C(PC)and protein S(PS)in the diagnosis of coronary artery stenosis in coro-nary heart disease.Methods A total of 186 patients with coronary artery disease admitted to Wujin Hospital Affiliated to Jiangsu University(Changzhou Wujin People's Hospital)from April 2022 to April 2024 were prospectively selected as the study group,and the patients were grouped into mild,moderate and severe groups according to Gensimi scores,and another 186 patients with healthy physical examination during the same peri-od were selected as the control group.Enzyme-linked immunosorbent assay(ELISA)was used to detect IL-12p70 levels.Automatic coagulation instrument was used to detect the levels of PC and PS.The influencing factors of severe coronary artery stenosis in coronary heart disease were analyzed by multivariate Logistic re-gression analysis.Receiver operating characteristic(ROC)curve was plotted to analyze the diagnostic value of CCTA parameters combined with serum IL-12p70,PC and PS in the diagnosis of severe coronary artery steno-sis in coronary heart disease.Results The serum level of IL-12p70 in the study group was greatly higher than that in the control group(P＜0.05),and the levels of PC and PS were greatly lower than those in the control group(P＜0.05).Minimum lumen diameter(MLD),minimum tubular neck area(MLA),serum PC,and PS levels were sequentially decreased in the mild,moderate,and severe groups(P＜0.05),and percentage area stenosis(％AS),percentage diameter stenosis(％DS),and serum IL-12p70 levels were sequentially increased(P＜0.05).According to multivariate Logistic regression analysis,IL-12p70 was a risk factor for severe coro-nary artery stenosis in coronary heart disease(P＜0.05),and PC and PS were protective factors(P＜0.05).According to the ROC curve,the area under the curve(AUC)of MLD,MLA,％AS,％DS,serum IL-12p70,PC,and PS for the diagnosis of severe coronary artery stenosis in coronary heart disease was 0.810,0.767,0.782,0.779,0.776,0.809,and 0.805.The AUC of combined diagnosis for severe coronary artery stenosis in coronary heart disease was 0.982,which was better than that of individual diagnosis(Zcombination vs.MLD=2.489,Zcombination vs.MLA=2.502,Zcombination vs.％AS=2.531,Zcombination vs.％DS=2.602,Zcombination vs.IL-12p70=2.643,Zcombination vs.PC=2.537,Zcombination vs.PS=2.546,all P＜0.05).Conclusion Serum IL-12p70 is greatly increased in patients with coronary heart disease,PC and PS levels are greatly reduced.CCTA combined with serum IL-12p70,PC,and PS could effectively improve their value in diagnosing degree of coronary artery stenosis in cor-onary heart disease.
