急性冠脉综合征患者血清APN、HO-1水平与冠状动脉病变严重程度的相关性研究

目的通过测定急性冠脉综合征(acute coronary syndrome,ACS)患者血清脂联素(adiponectin,APN)及血红素加氧酶-1(heme oxygenase-1,HO-1)水平,分析其与冠状动脉病变程度的相关性,探讨二者在冠心病中的相互作用。方法入选160例行冠状动脉造影(CAG)患者,根据患者病史及CAG结果分为2组:急性冠脉综合征(ACS)组92例,稳定型心绞痛(SAP)组68例;50例对照组为非冠心病CAG阴性组。用Gensini评分系统对冠脉病变程度评分。根据Gensini评分系统对冠脉病变组分为Gensini积分≥30分组和<30分组,再根据冠脉病变支数分为单只、双支和3支病变组。采双抗体夹心ELISA法测定ACS组、SAP组、正常对照组血清APN、HO-1水平。分别比较其二者之间的相关性及与冠脉病变的严重程度(Gensini积分)的相关性。结果 ACS组和SAP组血清APN及HO-1水平均明显低于对照组(5.84±2.29)、(8.01±2.04)vs(15.27±2.51)mg/L;(24.08±7.88)、(32.86±10.97)vs(54.35±14.8)μg/L,P<0.01]。按冠状动脉病变支数分组,冠状动脉病变支数多者血清APN、HO-1水平较冠状动脉病变支数少者亦显著降低。Gensini积分≥30分APN、HO-1水平(5.75±2.28)mg/L、(22.27±6.5)μg/L]明显低于<30分组(7.55±2.29)mg/L、(32.38±10.6)μg/L,P<0.01]。APN与HO-1呈正相关(r=0.598,P<0.01),Gensini积分与血清APN、HO-1水平均呈负相关(r=-0.576,P<0.01;r=-0.456,P<0.01)。结论血清APN与HO-1密切相关,且与冠状动脉病变严重程度密切相关,且二者之间可能存在相互调节。

Correlation study on serum adiponectin and heme oxygenase-1 levels and severity of coronary artery disease in patients with acute coronary syndrome

Objective To study the correlation between the levels of serum adiponectin(APN) and heme oxygenase-1(HO-1) and the severity of coronary artery disease in the patients with acute coronary syndrome(ACS),and investigate the interaction between APN and HO-1 in coronary heart disease.Methods One-hundred-and-sixty patients who had positive results in coronary angiography(CAG) were divided in an ACS group(n=92) and a stable angina pectoris(SAP) group(n=68) according to their medical histories and CAG results.In ad...
