【摘要】目的 研究同型半胱氨酸(Hcy)與老年人頸動(dòng)脈粥樣硬化斑塊的關(guān)系,為老年人頸動(dòng)脈粥樣硬化的防治提供依據(jù)。方法 隨機(jī)選取2018年1月~12月本院60歲以上老年住院患者108例作為研究對(duì)象,所有患者均經(jīng)血管超聲檢查證實(shí)存在頸動(dòng)脈粥樣硬化斑塊。其中,男58例,女50例,平均年齡(72.58±8.43)歲,另選取同期住院老年患者100例作為對(duì)照組,無頸動(dòng)脈粥樣硬化斑塊形成,其中,男54例,女46例,平均年齡(72.34±8.28)歲。所有研究對(duì)象均于晨起抽取靜脈血檢驗(yàn)Hcy水平。采用t檢驗(yàn)分析頸動(dòng)脈粥樣硬化斑塊與Hcy之間的關(guān)系。結(jié)果 Hcy水平在頸動(dòng)脈粥樣硬化斑塊組中為17.46 umol/L明顯高于對(duì)組照的12.78 umol/L,差異有統(tǒng)計(jì)學(xué)意義(P<0.001)。結(jié)論 Hcy水平升高與頸動(dòng)脈粥樣硬化有關(guān),是老年人頸動(dòng)脈粥樣硬化斑塊形成的一個(gè)危險(xiǎn)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.
【Key words】Homocysteine;Carotid atherosclerosis;Plaque
同型半胱氨酸(Hcy)是蛋氨酸代謝產(chǎn)生的中間物質(zhì),其本身并不參與合成蛋白質(zhì),其代謝受多種因素影響,遺傳、營(yíng)養(yǎng)、疾病、藥物、年齡和性別、大量飲酒、吸煙、咖啡類飲品、缺乏鍛煉、精神因素等均可影響同型半胱氨酸的代謝。已有大量研究證實(shí),Hcy是心腦血管疾病的獨(dú)立危險(xiǎn)因素[1],在冠狀動(dòng)脈粥樣硬化性心臟病及腦卒中患者中,Hcy均明顯升高[2-3]。研究顯示,Hcy與頸動(dòng)脈粥樣硬化有關(guān),在頸動(dòng)脈粥樣硬化患者中Hcy明顯升高,且與頸動(dòng)脈粥樣硬化程度呈正相關(guān)[4]。但在老年人中關(guān)于Hcy與頸動(dòng)脈粥樣硬化斑塊的研究尚不多,本文旨在研究Hcy與老年人頸動(dòng)脈粥樣硬化斑塊的關(guān)系,為老年人頸動(dòng)脈粥樣硬化的防治提供依據(jù),現(xiàn)報(bào)告如下。
1 資料與方法
1.1 一般資料
隨機(jī)選取2018年1月~12月本院60歲以上老年住院患者108例作為研究對(duì)象,所有患者均經(jīng)血管超聲檢查證實(shí)存在頸動(dòng)脈粥樣硬化斑塊,其中,男58例,女50例,平均年齡(72.58±8.43)歲。排除標(biāo)準(zhǔn):腦梗死;腦出血急性期;急性心肌梗死;缺血性心肌病;腎功能不全;貧血。另選取同期住院老年患者100例作為對(duì)照組,無頸動(dòng)脈粥樣硬化斑塊形成,其中,男54例,女46例,平均年齡(72.34±8.28)歲。兩組患者一般資料(性別、平均年齡等)比較,差異無統(tǒng)計(jì)學(xué)意義(P>0.05)。
1.2 方法
以7.5~10 MHz作為探頭頻率,采用荷蘭PHILIPS公司ie33超聲儀對(duì)所有患者進(jìn)行檢測(cè),檢查雙側(cè)頸總、頸內(nèi)、頸外動(dòng)脈,檢查時(shí)囑患者將頭偏向?qū)?cè)一側(cè),觀察是否有粥樣硬化斑塊形成。并在晨起空腹時(shí)抽取靜脈血,檢測(cè)血
