Abstract:
Objective To observe the correlation between zinc-a2-glycoprotein (ZAG) in human plasma and the degree of coronary atherosclerosis lesion.Methods A total of 242 research subjects were included.The clinical indexes were perfected and plasma ZAG level was detected.The coronary angiography was performed.The subjects were divided into the coronary atherosclerosis group (CAD group) and control group according to the examination results.The Gensini score was used to assess the degree of coronary artery lesion,different degree subgroups were divided according to the assessment results.The correlation between the ZAG level with the clinical indexes was analyzed by Spearman analysis.The ROC curve was used to evaluate the efficiency of ZAG in the diagnosis of coronary atherosclerosis and its sensitivity and specificity were analyzed.Results The plasma ZAG level in the CAD group was significantly lower than that in control group,the difference was statistically significant [(45.12±5.02)μg/mL vs.(53.93±2.96)μg/mL,P＜0.01].With the increase of Gensini score,plasma ZAG level showed the decreasing trend,the difference among the groups were statistically significant (P＜0.05).The Spearman correlation analysis showed that body mass index (BMI),waist circumference and waist to hip ratio(WHR) were negatively correlated with ZAG (P＜0.05),and positively correlated with high density lipoprotein cholesterol(HDL-C,P＜0.05).The sensitivity of plasma ZAG for evaluating coronary atherosclerosis was 89.8％ and its specificity was 91.2％.Conclusion Plasma ZAG is negatively correlated with the severity of coronary atherosclerosis lesion,and its level detection has a certain value in the screening of coronary atherosclerosis.
