Résumé
Objective To analyze the relationship and clinical meaning of serumglutamyl transpeptidase (GGT) level with left atrial diameter.Methods All the 320 essential hypertension patients from Ganzhou People′s Hospital were divided into normal left atrial group and enlarged left atrial group based on the size of left atrial diameter.Fasting blood glucose,serum lipid,routine laboratory tests,hepatic and renal function and blood pressure were measured by routine methods,and used for analyzing between groups.Results Among essential hypertension patients,the GGT level in enlarged left atrial group [(24.78±10.93)U/L] was lower than normal left atrial group[(35.23±12.46)U/L] (P=0.004).Multiple linear regression analysis showed that the serum GGT was negatively correlated with left atrial diameter (P=0.032),and logistic regression analysis showed that GGT was a protective factor for enlarged left atrial (OR=0.424,P=0.026).Conclusion Our study demonstrated the level of GGT was negatively with left atrial diameter among essential hypertension patients,and monitoring the changes of serum liver enzyme may has significant effect on the early detection of enlarged left atrial diameter.
Résumé
Objective To analyze the association of serum γ-glutamyl transpeptidase(γ-GT)level with carotid intima media thickness(IMT) in essential hypertension.Methods All the 300 essential hypertension patients and 70 healthy controls were from Ganzhou People′s Hospital.They were divided into healthy control group(70 cases),hypertension with out arteriosclerosis group(141 cases) and hypertension with arteriosclerosis group(159 cases) based on carotid IMT.Fasting blood glucose,serum lipid,routine laboratory tests,hepatic and renal function were detected by routine methods.The one-way analysis of variance and χ2-test were used to compared among the three groups,and the relationship of γ-GT with IMT was assessed by using the Spearman correlation coefficient,multiple linear regressions and Logistic regression analysis.Results The diastolic blood pressure,body mass index,fasting blood glucose,glomerular filtration rate and glycosylated hemoglobin had no differences among the three groups(P>0.05),but systolic pressure,triacylglycerol,total cholesterol,high density lipoprotein cholesterol,aspartate transaminase(AST),low density lipoprotein cholesterol alanine,transaminase(ALT) and γ-GT had significant differences among the three groups(P<0.05).Multiple linear regression analysis showed that the serum γ-GT(β=-0.345,95%CI was-0.005——0.511,P=0.036) was also negatively correlated with IMT,and Logistic regression analysis showed that γ-GT(OR=0.569,95%CI was 0.237-0.867,P=0.029)was a protective factor for atherosclerosis.Conclusion Our study demonstrated the level of γ-GT is negative with IMT among essential hypertension patients,and monitoring the changes of serum liver enzyme might has significant effect on the early detection of arteriosclerosis.
