Abstract:
Objective To investigate the association of insulin resistance(IR)and its related indices,including triacylglycerol-glucose(TyG)index and metabolic score of insulin resistance(Mets-IR),with the occurrence of early neurological deterioration(END)in patients with branch atheromatous disease(BAD),and develop a risk prediction model based on these factors.Methods A total of 189 BAD patients were consecutively recruited from the Department of Neurology of the Second Affiliated Hospital of Zhengzhou University between March 2020 and August 2024.Based on the occurrence of END within 7 d after admission,the participants were stratified into END(75 cases)and non-END(114 cases)groups.Demographic characteristics,clinical parameters,TyG index and Mets-IR values were systematically collected and analyzed.Multivariate logistic regression analysis was performed to identify independent risk factors for END in BAD-related stroke.Receiver operating characteristic curve(ROC)analysis was subsequently conducted to evaluate the predictive performance of significant variables,followed by construction of a nomogram prediction model.Results The END group exhibited significantly elevated fasting blood glucose[6.47(5.74,7.86)mmol/L vs 5.83(5.14,6.70)mmol/L]and triacylglycerol[1.65(1.21,2.04)mmol/L vs 1.27(0.99,1.57)mmol/L]levels,higher body mass index[25.02(23.88,26.67)kg/m2 vs 23.71(22.66,25.27)kg/m2]and TyG index(9.03±0.41 vs 8.71±0.45),and increased Mets-IR(39.98±4.23 vs 36.85±4.38)and NIHSS score[5.00(3.00,7.00)vs 3.00(2.00,5.00)]at admission when compared with the non-END group(P＜0.05).Multivariate logistic regression analysis showed that high TyG index(OR=3.751,95％CI:1.592-9.202,P＜0.01),Mets-IR(OR=1.146,95％CI:1.049-1.252,P＜0.01),and NIHSS score at admission(OR=1.279,95％CI:1.128-1.451,P＜0.01)were risk factors for the occurrence of END in BAD patients(P＜0.05).ROC curve indicated that the AUC value of TyG index,Mets-IR,and NIHSS score at admission in predicting END occurrence was 0.698(95％CI:0.623-0.774,P＜0.01),0.698(95％CI:0.620-0.775,P＜0.01),and 0.666(95％CI:0.586-0.745,P＜0.01),respectively.The nomogram prediction model based on these factors demonstrated significant clinical benefits by decision curve analysis and goodness of fit in internal calibration analysis.Conclusion IR shows significant association with END in BAD patients.The IR related indices,TyG index and Mets-IR,have certain predictive efficiency for occurrence and progression of END.
