探讨血清视黄醇结合蛋白4与冠心病的相关性

Serum retinol-binding protein 4 correlated with coronary heart disease

目的 观察冠心病患者血清视黄醇结合蛋白4(RBP4)水平,并探讨RBP4与冠心病的关系.方法 64例冠心病患者分为急性心肌梗死(AMI)组10例,不稳定型心绞痛(UAP)组42例,稳定型心绞痛(SAP)组12例,另选择21例冠状动脉造影结果正常者为对照组.采用酶联免疫吸附法(ELISA)测定血清RBP4水平.结果 血清RBP4在AMI和UAP组中高于SAP组和对照组,差异有统计学意义(P＜0.05),在SAP组与对照组之间差异无统计学意义(P＞0.05);血清RBP4在单支、双支、三支病变组中均高于对照组(P＜0.05),但在单支、双支与三支病变组之间差异均无统计学意义(P＞0.05).结论 RBP4可作为预测斑块稳定性的标志物,为冠心病危险分层及采取积极干预措施提供依据,但不能反映冠状动脉狭窄程度及范围.

Objective To investigate the serum retinol - binding protein 4 ( RBP 4 ) of coronary heart disease (CHD)patients and evaluate whether plasma macrophage migration inhibitory factor were associated with CHD. Methods Sixty -four patients with CHD were divided into the acute myocardial infarction (AMI) group ( n = 10), the unstable angina pectoris (UAP) group ( n = 42) and the stable angina pectoris(SAP) ( n = 12),21 normal subjests without CHD diagnosed by CAG served as the control group. The serum level of RBP4 measured by enzyme linked immune sorbent assay (ELISA). Results The serum level of RBP4 were higher in AMI and UAP group thai in SAP group and control group ( P ＜ 0. 05 ). The mean level of RBP4 in SAP group was not differently significantly, compared with that in control ( P ＞ 0. 05 ) ;The mean level of in single, double and three vessel lesion group were higher than that in control group (P ＜0. 05 ),but the serum levels of RBP4 among single, double and three were not significant different ( P ＞ 0. 05).Conclusions RBP4 may act as one of vulnerable plaques,we can take active to stabilize vulnerable plaques and decrease the occurrence of cardiac events,but may not reflect the severity of artery stenosis.
