【摘要】 目的 研究血清同型半胱氨酸(Hcy)与冠状动脉病变之间存在的相关性。方法 70例已行冠状动脉造影患者, 根据患者的疾病类型进行分组, 其中稳定型心绞痛患者27例(SA组), 急性冠状动脉综合征患者43例(ACS组);同期40例健康体检者作为对照组, 采用循环酶法测定所有研究对象的血清Hcy水平, 研究其与冠状动脉病变程度之间存在的相关性。结果 三组血清Hcy水平比较, ACS组明显较SA组和对照组高, SA组较对照组高, 差异均具有统计学意义(P<0.05);ACS组血清Hcy水平与冠状动脉病变的Gensini积分呈正相关(r=0.472, P<0.05)。结论 冠心病患者, 其血清Hcy水平明显上升, 提示两者之间具有密切相关性, 可采用血清Hcy水平测定作为冠状动脉病变情况的预测指标。

【Abstract】 Objective To research correlation between serum homocysteine (Hcy) and coronary artery disease. Methods A total of 70 patients receiving coronary arteriography were divided by their disease types into 27 cases with stable angina pectoris (SA group) and 43 cases with acute coronary syndrome (ACS group). There were 40 healthy people at the same time period as control group. Enzymatic cycling assay was applied to detect serum Hcy levels in all study subjects for research of correlation between serum Hcy and coronary artery disease degree. Results ACS group had obviously higher serum Hcy level than SA group and control group, and SA group also had higher serum Hcy level than control group. Their differences all had statistical significance (P<0.05). ACS group had positive correlation between serum Hcy and Gensini score of coronary artery disease (r=0.472, P<0.05). Conclusion Remarkable increase of serum Hcy level in coronary heart disease patients shows a close correlation between them. Implement of serum Hcy level detection can act as predictive index for coronary artery disease condition.

近年来, 冠状动脉病变在我国的发病率呈现不断上升的趋势, 对人类的健康造成严重威胁。随着医学领域对该疾病的研究逐渐深入, 发现在心脑血管疾病的危险发病因素中包含高血浆同型半胱氨酸(HHcy)[1]。HHcy是指人体中的血清Hcy水平>10 μmol/L, 对细胞及基因具有毒性作用。有研究结果显示, 血清Hcy水平与急性心肌梗死的发病及病情发展具有密切相关性[2]。本次研究选取已行冠状动脉造影的SA、ACS患者及健康人群作为研究对象, 检测所有研究对象的血清Hcy水平, 取得满意的效果, 现报告如下。
1 资料与方法
1. 1 一般资料 选取2013年7月~2015年2月已行冠状动脉造影患者70例, 根据患者的疾病类型进行分组, 包括稳定型心绞痛27例(SA组), 急性冠状动脉综合征43例(ACS组), 并选取同期健康体检者40例作为对照组。SA组中, 男17例, 女10例, 年龄54~78岁, 其中13例患高血压, 16例患高血脂, 19例患糖尿病, 10例男性患者有长期吸烟史。……
