[摘要] 目的 探讨血清同型半胱氨酸(Hcy)及脂蛋白A(Lp-a)与冠心病的相关性。方法 方便选取2015年5月—2017年5月该院收治的142例冠心病患者为研究对象,依据诊断结果分为心绞痛组(73例)和心肌梗死组(69例),另择取同期该院70名健康体检者为对照组,测定3组Hcy和Lp-a水平,分析两项指标与冠心病的相关性。结果 心肌梗死组Hcy(24.6±12.8)μmol/L,高于心绞痛组和对照组,差异有统计学意义(t=3.91,P<0.05;t=5.88,P<0.05)。心肌梗死组Lp-a(73.9±29.1)noml/L,高于心绞痛组和对照组,差异有统计学意义(t=10.54,P<0.05;t=13.35,P<0.05)。Logistic回归分析显示,Hcy、Lp-a是冠心病独立危险因素(OR=1.594,P<0.05;OR=3.532,P<0.05)。结论 Hcy与Lp-a是冠心病的独立危险因素,加强对Hcy和Lp-a的监测对冠心病诊治及预后评估具有指导意义。

[Abstract] Objective This paper tries to investigate the correlation between serum homocysteine (Hcy) and lipoprotein A (Lp-a) and coronary heart disease. Methods 142 cases of coronary heart disease patients from May 2015 to May 2017 in this hospital were convenient selected divided into angina group (73 cases) and myocardial infarction group (69 cases), 70 cases of healthy people were chosen as the control group. The three groups were measured Hcy and Lp-a levels, correlation analysis and coronary heart disease. Results The Hcy (24.6±12.8)μmol/L in the myocardial infarction group was higher than that of the angina pectoris group and the control group. The difference was statistically significant(t=3.91, P<0.05;t=5.88, P<0.05). Lp-a in myocardial infarction group(73.9±29.1) noml/L, higher than the angina pectoris group and the control group, the difference was statistically significant(t=10.54, P<0.05; t=13.35, P<0.05). Logistic regression analysis showed that Hcy and Lp-a were independent risk factors for coronary heart disease(OR=1.594, P<0.05; OR=3.532, P<0.05). Conclusion Hcy and Lp-a are independent risk factors of coronary heart disease. Monitoring of Hcy and Lp-a is of guiding significance for the diagnosis and treatment of coronary heart disease.

冠心病是冠状动脉血管粥样硬化病变引起管腔狭窄、阻塞,造成心肌缺血、缺氧性坏死所引起的心脏病,发病率和死亡率在所有心脏病中均居首位,严重危害人群生命健康[1]。引起冠心病的危险因素众多,作用机制复杂,现代研究发现,其发生除与个体年龄、烟酒史、血糖、血脂、血压、不良生活饮食习惯等存在密切关联以外,也与血清同型半胱氨酸(Hcy)、脂蛋白A(Lp-a)等生化物质存在相关性[2]。文章现以2015年5月—2017年5月该院收治的142例患者为例,对Hcy、Lp-a与冠心病的相关性进行分析和探讨,现报道如下。

1 资料与方法

1.1 一般资料

方便选取该院心内科收治的142例冠心病患者为研究对象,依据诊断结果将入选病例分为两组。心绞痛组(73例):男47例,女26例;年龄(57.2±8.4)岁;BMI(23.6±2.1);合并高血压29例,糖尿病17例。心肌梗死組(69例):男45例,女24例;年龄(56.9±8.1)岁;BMI(23.7±1.8);合并高血压30例,糖尿病14例。另择取同期该院70名健康体检者为对照组:男43名,女27名;年龄(56.3±7.2)岁;BMI(23.0±1.7)岁;合并高血压17例,糖尿病11例。3组一般资料差异无统计学意义(P>0.05),具有可比性。……
