Study on the relationship between Acute Coronary Syndrome and serum homocysteine

Objective To discuss the relationship between serum homocysteine (Hcy) level and severity of acute coronary syndrome(ACS) through measuring the level of serum Hey in the patients with ACS.Methods 95 patients who were diagnosed ACS were divided into two groups:40 cases of unstable angina(UA) and 55 cases of a cute myocardial infarction(AMI).30 individuals were chosen as normal control(NC).In addition,according to the results of coronary angiography,the same 95 patients were further divided into three subgroups which were single-vessel disease( 28cases),double-vessel disease ( 36cases ) and multi-vessel disease ( 31 cases ).Level of serum Hcy was measured in all groups.Results Serum Hcy level of ACS patients was significantly higher than NC group( P ＜ 0.01 ).The level of serum Hcy in AMI group was significantly higher than that in UA group( P ＜ 0.05 ).The Hcy level in the multi-vessel disease group,double-vessel disease group and single-vessel disease group were increased in turn,and the difference of pairwise comparison was statistically significant ( P ＜ 0.05 ).Conclusion The serum Hcy level has rela tionship with the severity of coronary lesions and is directly proportional to the number of coronary artery lesions.The result suggests that the level of serum Hcy maybe play an important role in the prevention,diagnosis,treatment and monitoring of ACS.
