Abstract:
Aim To analyze the correlation between serum retinol-binding protein 4(RBP4),low density lipo-protein cholesterol to albumin ratio(LDLC/Alb),monocyte to high density lipoprotein ratio(MHR)and plaque stability in carotid atherosclerosis population and their predictive value for acute ischemic stroke(AIS).Methods A total of 197 patients with asymptomatic carotid atherosclerosis admitted to our hospital from September 2021 to January 2023 were selected for a prospective cohort study,and they were categorized into occurred group and non-occurred group according to whether AIS occurred within 12 months.Baseline information at time of visit,results of the cervical ultrasonography and serum RBP4,LDLC/Alb,MHR levels were compared between the two groups.Spearman/Pearson and receiver operating characteristic(ROC)curve were used to analyze the corr-elation of RBP4,LDLC/Alb and MHR with carotid atherosclerosis and plaque stability,and the value of predicting AIS in carotid atherosclerosis population.Hosmer-Lemeshow goodness of fit test was used to evaluate the calibration ability of serum RBP4,LDLC/Alb and MHR to jointly predict AIS in carotid atherosclerosis population.Results The carotid intima-media thickness(IMT)was higher in occurred group than that in non-occurred group.There were more soft plaques and mixed plaques in occurred group than in non-occurred group(P＜0.05).Serum levels of RBP4,LDLC/Alb and MHR were higher in occurred group than those in non-occurred group(P＜0.05).The correlation analysis showed that the levels of serum RBP4,LDLC/Alb and MHR were positively correla-ted with IMT(r=0.803,0.740,0.710)and plaque properties(r=0.736,0.685,0.703)(P＜0.001).ROC curve a-nalysis showed that the AUC of serum RBP4,LDLC/Alb and MHR in predicting AIS in carotid atherosclerosis population was 0.796,0.821 and 0.828,respectively,and the AUC of MHR was the largest;the AUC of the combination of serum RBP4,LDLC/Alb and MHR was 0.936,which was higher than that of MHR(Z=2.978,P＜0.05),the predictive sensi-tivity and specificity were 88.24％and 87.40％.Hosmer-Lemeshow goodness of fit test showed that there was no signifi-cant difference between serum RBP4,LDLC/Alb and MHR in predicting AIS and the actual observation value in carotid atherosclerosis population(P＞0.05),and the prediction model had good calibration ability.Conclusion Serum RBP4,LDLC/Alb,and MHR are positively correlated with carotid atherosclerosis and plaque stability,and can predict the occurrence of AIS.Combined detection of the three can be used as a method for early identification of potential high-risk populations for AIS,providing a new,quantifiable guidance scheme for the prevention and treatment of AIS in carotid ath-erosclerotic population.
