摘要
目的探索血浆中氧化三甲胺(trimethylamine N-oxide,TMAO)及其前体物质的浓度与冠状动脉粥样硬化性心脏病(以下简称冠心病)(coronary heart disease,CHD)的关系。方法选取首都医科大学附属北京天坛医院心内科可疑CHD患者88例,根据冠状动脉造影结果将患者分为CHD组和对照组。利用高效液相法测患者血浆TMAO及其前体物质胆碱、肉碱、三甲胺乙内酯和三甲氨基丁内盐的浓度,分析两组患者血浆TMAO浓度及其前体物质与CHD的关系。结果CHD组患者血浆TMAO浓度明显升高,差异有统计学意义[(6.20±3.57)μmol/L vs(3.90±2.26)μmol/L,P<0.05];两组血浆中胆碱、肉碱、三甲胺乙内酯和三甲氨基丁内盐浓度差异均无统计学意义(P>0.05)。多因素Logistic回归分析,血浆TMAO浓度与CHD有关联(OR=1.35,P<0.05),血浆TMAO浓度升高,CHD的危险性增加。结论血浆中TMAO的浓度与CHD密切相关,而与TMAO前体物质浓度无显著相关性。
Objective To study the associations of plasma trimethylamine N-oxide(TMAO)and its precursors with coronary heart disease(CHD).Methods Patients with suspected CHD were enrolled in cardiology department of Beijing Tiantan Hospital,and divided into CHD and control groups according to angiography results.Plasma TMAO,choline,carnitine,betaine and butyrobetaine of all patients were measured by high-performance liquid chromatography,and the differences of plasma TMAO and its precursors between CHD and control patients were analyzed by statistical methods.Results The difference of plasma TMAO between CHD and control groups was significance[(6.20±3.57)mol/L vs(3.90±2.26)μmol/L,P<0.05],but the differences of choline,carnitine,betaine and butyrobetaine between two groups were not significant(P>0.05).And plasma TMAO was still associated with CHD significantly in multivariate Logistic regression analysis(OR=1.35,P<0.05).Conclusion CHD was associated with plasma TMAO level significantly,but not its precursors.
