摘要:

目的 探讨血脂及同型半胱氨酸(Hcy)与急性冠状动脉综合征(ACS)的相关性。方法 选取经冠状动脉造影确诊的ACS患者118例,其中ST段抬高型心肌梗死(STEMI)30例、非ST段抬高型心肌梗死(NSTEMI)28例、不稳定型心绞痛(UA)60例。以胸痛就诊且经冠状动脉造影确定冠状动脉无明显狭窄的患者44例作为疾病对照组,以61名体检健康者作为正常对照组。检测所有对象血脂及Hcy水平,按美国纽约心脏病学会(NYHA)心功能分级标准将ACS患者分为NYHA Ⅰ~Ⅳ级。采用多因素Logistic回归分析评估ACS的危险因素。结果 ACS组血清脂蛋白(a)[Lp(a)]、Hcy水平明显高于疾病对照组及正常对照组(P<0.05);血清高密度脂蛋白胆固醇(HDL-C)、载脂蛋白(apo)A1水平明显低于疾病对照组及正常对照组(P<0.05)。血清三酰甘油(TG)、总胆固醇(TC)、低密度脂蛋白胆固醇(LDL-C)、apo B水平3组之间差异均无统计学意义(P>0.05)。STEMI组血清Lp(a)、Hcy水平明显高于NSTEMI组和UA组(P<0.05),血清HDL-C、apo A1水平明显低于NSTEMI组和UA组(P<0.05)。NSTEMI组与UA组之间血清Lp(a)、HDL-C、apo A1、Hcy水平差异均无统计学意义(P>0.05)。在NYHA Ⅰ~Ⅲ级的ACS患者中,随着NYHA分级的增高,血清Lp(a)及Hcy水平逐渐升高(P<0.05),血清HDL-C、apo A1水平NYHA各分级间差异均无统计学意义(P>0.05)。多因素Logistic回归分析结果显示,Lp(a)及Hcy升高为ACS的危险因素[比值比(OR)分别为4.590、2.808,95%可信区间(CI)分别为1.375~15.322、1.026~7.685]。结论 Lp(a)和Hcy 可能参与了冠状动脉粥样硬化的病变过程。Lp(a)和Hcy或可作为筛查ACS高危人群的血清学指标。

Abstract:

Objective To analyze the correlations of serum blood lipids and homocysteine(Hcy) with acute coronary syndrome(ACS). Methods A total of 118 patients with ACS confirmed by coronary angiography,including 30 patients with ST-segment elevation myocardial infarction(STEMI),28 patients with non-ST-segment elevation myocardial infarction(NSTEMI) and 60 patients with unstable angina(UA),were enrolled. Totally,44 patients with chest pain confirmed by coronary angiography showing no significant stenosis of coronary arteries were enrolled as pathological control group,and 61 healthy subjects were enrolled as healthy control group. Serum blood lipids and Hcy levels were determined. The ACS patients were classified into New York Heart Association(NYHA) Ⅰ-Ⅳ according to NYHA cardiac function classification. Multi-variant Logistic regression analysis was used to evaluate the risk factors of ACS. Results The levels of serum lipoprotein(a)[Lp(a)] and Hcy in ACS group were higher than those in pathological control group and healthy control group(P<0.05),while the levels of serum high-density lipoprotein cholesterol(HDL-C)and apolipoprotein(apo)A1 in ACS group were lower than those in pathological control group and healthy control group(P<0.05). There was no statistical significance in serum triglyceride(TG),total cholesterol(TC),low-density lipoprotein cholesterol(LDL-C) and apoB levels among the 3 groups(P>0.05). Serum Lp(a) and Hcy levels in STEMI group were higher than those in NSTEMI group and UA group(P<0.05),and HDL-C and apo A1 levels were lower than those in NSTEMI and UA groups(P<0.05). There was no statistical significance in serum Lp(a),HDL-C,apo A1 and Hcy between NSTEMI group and UA group(P>0.05). The levels of Lp(a)and Hcy were increased with the increasing of NYHA cardiac function classification(P<0.05),and there was no statistical significance in serum HDL-C and apo A1 levels with NYHA cardiac function classification(P>0.05). Multi-variant Logistic regression analysis showed that serum Lp(a) and Hcy were risk factors for ACS [odds ratios(OR) were 4.590 and 2.808,respectively],and the 95% confidence intervals(CI) were 1.375-15.322 and 1.026-7.685,respectively. Conclusions Lp(a)and Hcy may be involved in the process of coronary artery disease. Serum Lp(a)and Hcy levels may be serological indicators for screening high-risk ACS population.
