2、所占的比例,同时检测血清胆固醇(TC)、甘油三酯(TG)、低密度脂蛋白胆固醇(LDL-C)、高密度脂蛋白胆固醇(HDL-C)水平。根据冠状动脉造影的结果将冠心病组分为1支、2支和3支病变组,观察其与Fib及sLDL的关系。结果冠心病组血浆Fib及血脂水平明显高于对照组(HDL-C低于对照组),P<0105,Fib与sLDL水平随冠状动脉病变支数增加而升高(P<0105)。sLDL与冠状动脉病变程度密切相关(r=01452,P<01001),与Fib水平呈正相关(y=4117x+44167)。结论sLDL是冠心病发病的独立
3、危险因素,Fib与sLDL呈正相关,Fib可能间接地对冠心病发病起一定作用。=关键词>纤维蛋白原;脂蛋白类,LDL;冠状动脉疾病;冠状血管造影术Relationshipbetweenfibrinogenandsmalllow-densityloipoproteinparticlesincoronaryheartdiseaseQINQin,GENGJie,CUIRang-zhuang,etal1TianjinChestHospital,Tianjin300051,China=Abstract>ObjectiveToinve
