血浆同型半胱氨酸及血脂与老年脑梗死的关系

目的 研究老年急性脑梗死(ACI)患者血浆同型半胱氨酸(HCY)与血脂水平的变化及其相关性.方法 观察组48例ACI患者,健康对照组30例.测定空腹血浆HCY和血脂水平.结果 ACI患者血浆同型半胱氨酸(HCY)、胆固醇(TC)、甘油三酯(TG)、低密度脂蛋白(LDL)均显著高于健康对照组,差异有统计学意义(均P＜0.01),而ACI患者高密度脂蛋白(HDL)较健康对照组低,差异有统计学意义(P＜0.01).而血浆Hcy含量与TC、TG、HDL-C、LDL-C含量的相关性均无统计学意义.结论 老年急性脑梗死患者血浆HCY及TC、TG、LDL水平较健康对照组均增高,而HDL降低,而血浆HCY和血脂之间无相关性,是老年脑梗死的一个独立危险因素.

The clinical significance of plasma homocysteine and lipids in aged patients with acute cerebral infarction

Objective To investigate the relationship between plasma homocysteine levels and lipids in aged patients with acute cerebral infarction(ACI).Methods Fourty-eight cases(observation group),who had been inpatients with cerebral infarction during May 2006 to May 2007,thirty healthy people(control group)contrasted and analyzed.Results The mean plasma homocysteine level and cholesterol(TC),triglycerides(TG),low density lipoprotein(LDL)of aged patients with acute cereral infarction were significantly,higher than those of the control group,but high density lipoprotein(HDL)was lower(P＜0.01).No significant correlation between Hcy level and TC,TG,HDL-C,LDL-C level in serum.Conclusion Plasma homocysteine lexrel and lipids all siginificantly increased in aged patients with acute cereral infarction,and homocysteinemia is not related with lipids,but is an independent risk factor for cerebral infarction.
