Objective To analyze the correlation of serum levels of GAT A-binding protein 3(GATA-3),T cell immunoglobulin domain and mucin domain protein-3(Tim-3)and retinoid-related orphan nuclear receptor gamma t(RORγt)with cardiac function and myocardial injury in-dicators in patients with coronary heart disease(CHD)and angina pectoris.Methods A retrospec-tive analysis was performed on 120 CHD patients with angina pectoris(observation group)in our hospital from December 2020 to December 2023.They were divided into stable angina subgroup(53 cases)and unstable angina subgroup(67 cases)according to the results of electrocardiography and coronary angiography.Another 120 healthy individuals taking physical examination in our hospital during the same period were subjected and served as the control group.ELISA was used to detect the serum levels of GATA-3,Tim-3 and RORγt.Left ventricular ejection fraction(LVEF),left ventricular end-diastolic diameter(LVEDD),left ventricular end-systolic diameter(LVESD),and left ventricular short-axis shortening rate(FS)were measured by echocardio-graphy.Creatine kinase(CK)and creatine kinase isoenzyme(CK-MB)were detected by biochemi-cal analyzer,and troponin Ⅰ(cTnⅠ)and heart fatty acid binding protein(H-FABP)were detected by electrochemiluminescence immunoassay.Pearson analysis was applied to analyze the correlation the correlation of serum levels of GATA-3,Tim-3 and RORγt with cardiac function and myocar-dial injury indicators.ROC curve was plotted to analyze the predictive value of the above three in-dicators for unstable angina.Results The serum levels of Tim-3 and ROR y t were significantly higher,and that of GATA-3 was obviously lower in the observation group than the control group(397.14±78.42 ng/L vs 246.45±56.81 ng/L,P＜0.01;93.18±19.94 ng/L vs 35.72±7.79 ng/L,P＜0.01;38.21±9.45 ng/L vs 71.62±14.98 ng/L,P＜0.01).The LVEDD and LVESD values were notably higher,while the LVEF and LVFS values were remarkably lower in the observation group than the control group(P＜0.01).The observation group has statistically higher cTnⅠ,CK,CK-MB,and H-FABP levels than the control group(P＜0.01).In the CHD patients with angina pectoris,serum GATA-3 level was positively correlated with LVEF and LVFS,and negatively with LVEDD,LVESD,cTnⅠ,CK,CK-MB,and H-FABP;Tim-3 and RORγt were negatively corre-lated with LVEF and LVFS,and positively with LVEDD,LVESD,cTnⅠ,CK,CK-MB,and H-FABP(P＜0.01).The AUC value of GATA-3,Tim-3,and RORγt alone and in combination in predicting unstable angina was 0.859,0.827,0.780,and 0.921,respectively,with that of combina-tion significantly higher than that of above indicators alone(Z=1.993,3.021,4.532,P=0.036,0.007,0.001).Conclusion As the disease progresses in CHD patients with angina pectoris,serum levels of Tim-3 and RORγt are increasing,while that of GATA-3 is decreasing,and all of them are closely associated with heart function and myocardial injury indicators.
