【摘要】目的 研究同型半胱氨酸(Hcy)与老年人颈动脉粥样硬化斑块的关系,为老年人颈动脉粥样硬化的防治提供依据。方法 随机选取2018年1月~12月本院60歲以上老年住院患者108例作为研究对象,所有患者均经血管超声检查证实存在颈动脉粥样硬化斑块。其中,男58例,女50例,平均年龄(72.58±8.43)岁,另选取同期住院老年患者100例作为对照组,无颈动脉粥样硬化斑块形成,其中,男54例,女46例,平均年龄(72.34±8.28)岁。所有研究对象均于晨起抽取静脉血检验Hcy水平。采用t检验分析颈动脉粥样硬化斑块与Hcy之间的关系。结果 Hcy水平在颈动脉粥样硬化斑块组中为17.46 umol/L明显高于对组照的12.78 umol/L,差异有统计学意义(P<0.001)。结论 Hcy水平升高与颈动脉粥样硬化有关,是老年人颈动脉粥样硬化斑块形成的一个危险因素。

【Abstract】Objective To study the relationship between Homocysteine and carotid atherosclerotic plaque in elder people, and provide the evidence for treating and preventing carotid atherosclerosis.Methods One hundred and eight patients with carotid atherosclerotic plaque confirmed by vessel ultrasound examination were chosen as observation group (n=108, male 58, female 50 and average age=72.58±8.43).The control group were chosen from patients without carotid atherosclerotic plaque in the same term (n=100, male 54, female 46 and average age=72.34±8.28). All subjects were tested plazma homocysteine.The relationship between plazma homocysteine and carotid atherosclerotic plaque was analyzed by using t test.Results The leval of plazma homocysteine in observation group were higher than control group(P<0.001).Conclusion The findings indicate the elevation of plazma homocysteine is related to carotid atherosclerosis,it is a risk factor in elder people with carotid atherosclerotic plaque.

同型半胱氨酸(Hcy)是蛋氨酸代谢产生的中间物质,其本身并不参与合成蛋白质,其代谢受多种因素影响,遗传、营养、疾病、药物、年龄和性别、大量饮酒、吸烟、咖啡类饮品、缺乏锻炼、精神因素等均可影响同型半胱氨酸的代谢。已有大量研究证实,Hcy是心脑血管疾病的独立危险因素[1],在冠状动脉粥样硬化性心脏病及脑卒中患者中,Hcy均明显升高[2-3]。研究显示,Hcy与颈动脉粥样硬化有关,在颈动脉粥样硬化患者中Hcy明显升高,且与颈动脉粥样硬化程度呈正相关[4]。但在老年人中关于Hcy与颈动脉粥样硬化斑块的研究尚不多,本文旨在研究Hcy与老年人颈动脉粥样硬化斑块的关系,为老年人颈动脉粥样硬化的防治提供依据,现报告如下。
1 资料与方法
1.1 一般资料
随机选取2018年1月~12月本院60岁以上老年住院患者108例作为研究对象,所有患者均经血管超声检查证实存在颈动脉粥样硬化斑块,其中,男58例,女50例,平均年龄(72.58±8.43)岁。排除标准:脑梗死;脑出血急性期;急性心肌梗死;缺血性心肌病;肾功能不全;贫血。另选取同期住院老年患者100例作为对照组,无颈动脉粥样硬化斑块形成,其中,男54例,女46例,平均年龄(72.34±8.28)岁。两组患者一般资料(性别、平均年龄等)比较,差异无统计学意义(P>0.05)。
1.2 方法
以7.5~10 MHz作为探头频率,采用荷兰PHILIPS公司ie33超声仪对所有患者进行检测,检查双侧颈总、颈内、颈外动脉,检查时嘱患者将头偏向对侧一侧,观察是否有粥样硬化斑块形成。并在晨起空腹时抽取静脉血,检测血
