Abstract:
Objective To explore the correlation between 5-LO,Hcy and the stability of carotid artery arteriosclerosis (CAS).Methods A total of 176 patients diagnosis as CAS were assigned as study group then subdivided into stable plaques SP (group) and instable plaques IP(group).108 healthy volunteers were assigned as control group.The serum levels of 5-LO and Hcy were measured and the relationship between the two groups were analyzed.The risk factors of CAS were investigated by Logistic regression analysis and 5-LO and Hcy were used to predict the stability of carotid atherosclerotic plaque by drawing ROC curve.Results The levels of 5-LO and Hcy in the IP group were higher than those in the SP group and the control group(P＜0.05).The level of Hcy in SP group was higher than that in the control group (P＜0.05),while there is no statistical significance between SP and control group in the level of serum 5-LO(P＞0.05).Logistic regression analysis showed that 5-LO,Hcy and diabetes were the risk factors of CAS (P＜0.05).The ROC curve indicate that the optimal cut-off concentration of 5-LO was 232.89 pg/mL for discriminating the IP from SP,the sensibility and specificity were 84.4％ and 81.8％ respectively.And the optimal cut-off concentration of Hcy was 12.53 μmol/L and the sensibility and specificity were 70.1％ and 66.7％ respectively.Conclusion Serum 5-LO and Hcy are risk factors for predicting the stability of CAS plaques;regulating both levels may be a potential target for clinically stable CAS.
