血清铁蛋白在急性冠状动脉综合征临床应用研究中的作用

The clinical application value of serum ferritin in acute coronary syndromes

目的探讨在急性冠状动脉综合征(ACS)患者中,血清铁蛋白(SF)与ACS及其他心血管疾病危险因素之间的相关性。方法选取ACS患者110例,其中不稳定性心绞痛(UA)组46例、非ST段抬高型心肌梗死(NSTEMI)组30例和ST段抬高型心肌梗死(STEMI)组34例;同期冠状动脉造影显示冠状动脉正常的患者为对照组42例,检测SF、超敏C反应蛋白(hs-CRP)和血脂水平,比较组间SF的差异并分析SF与hs-CRP及各血脂参数之间的相关性。结果 UA组、NSTEMI组、STEMI组与对照组比较SF水平显著升高(P<0.05),且NSTEMI组、STEMI组明显高于UA组。相关性分析显示,SF与hs-CRP、三酰甘油(TG)呈正相关,与高密度脂蛋白胆固醇(HDL-C)呈负相关。结论 SF在ACS患者中明显升高,且与hs-CRP、脂质代谢紊乱密切相关,SF检测有助于ACS患者临床分型和危险度分层。

Objective To investigate the relationship of serum ferritin（SF） and acute coronary syndrome（ACS） .Methods ACS group（n= 110） was divided into unstable angina（UA） subgroup（n= 46） ,non-ST-segment elevation myocardial infarction （NSTEMI） subgroup（n=30） and ST-segment elevation myocardial infarction（STEMI） subgroup（n=34） according to clinical da-ta ,coronary angiography and electrocardiogram examination .The normal coronary patients provided as control group（n=42） .The levels of serum ferritin ,hs-CRP and serum lipids were determined and the differences of SF among the groups were analyzed .The correlation of hs-CRP ,TG ,LDL-C ,HDL-C ,TC and SF were also analyzed .Results Compared with control group ,the level of SF in UA ,NSTEMI ,STEMI were significantly increased（P〈0 .05） .Comparison in the levels of SF in NSTEMI ,STEMI group and UA group had significant difference（P〈0 .05） .Correlation analysis indicated that the level of SF were positively correlated with hs-CRP ,TG and negatively associated with HDL-C .Conclusion The level of SF significantly increased in patients with ACS and has a positive relationship with hs-CRP and the disorder of lipid metablism .SF helps in assessing the clinical classification and risk strati-fication in patients with ACS .
