缺血性脑血管病血清同型半胱氨酸和纤维蛋白原水平的变化及其相关性分析

Changes and correlation analysis between serum homocysteine and plasma fibrinogen in ischemic cerebrovascular disease

目的 探讨缺血性脑血管病(ICVD)患者血清同型半胱氨酸(Hcy)和纤维蛋白原(Fg)水平变化及其之间的相关性。方法 收集74例ICVD患者(ICVD组)、40例非脑血管病患者(对照组)血液标本,采用荧光偏振光法测定血清Hcy,电化学发光法测定叶酸,免疫比浊法测定Fg,同时常规测定血脂水平。结果 ICVD组血清Hcy和血浆Fg水平均较对照组显著升高(均P<0. 05),但两者之间无相关性;两组患者血清叶酸水平差异无显著性(P>0. 05);多元Logistic回归分析显示高血压、高胆固醇、高Fg和高Hcy对ICVD的发生有显著作用。结论 高Hcy血症和高Fg血症分别是ICVD的独立危险因素。

Objective To investigate the change of serum homocysteine (Hcy) and plasma fibrinogen (Fg) levels in patients with ischemic cerebrovascular diseases (ICVD) and the correlation between Hcy and Fg.Methods Blood samples were collected from 74 patients with ICVD and 40 controls. The concentrations of Hcy, folate and Fg were determinated by means of fluorescence polarization immunoassay, electrochemiluminescence, and immunoturbidimetry, respectively. In the meantime, plasma lipid was detected by routine method.Results Both Hcy and Fg levels in the patients with ICVD increased significantly as compared with the controls (all P<0.05),but no correlation was found between Hcy and Fg.The folate concentration was no significant difference between the two groups( P>0.05). Multivariate logistic regression analysis indicated that hypertension, high cholesterol, high Fg and high Hcy concentrations played significiant roles in ICVD.Conclusion Both hyperhomocysteinemia and hyperfibrinogenemia are independent risk factors of ICVD.
