摘要 目的测定冠心病患者血浆胃饥饿素(ghrelin)水平变化,探讨其在冠心病发生、进展中的作用。方法冠心病组,共166例,随机分为急性冠脉综合征(ACS)组(94例),稳定性冠心病组(72例);对照组65例。抽取清晨静息空腹血。用EDTA—抑肽酶抗凝,4℃,3000 r/min离心后分离血浆,零下70-80℃保存,测定时冻融,所有标本同批ELISA法测定ghrelin。观察ghrelin的水平变化。结果冠心病患者血浆ghrelin水平(1.74±0.5)mg/L显著低于正常对照组(2.30±0.69)mg/L(P〈0.05);ACS组血浆ghrelin水平(1.84±0.49)mg/L显著低于稳定性冠心病组(2.11±0.54)mg/L(P〈0.05);冠心病组患者血浆ghrelin水平与冠脉病变Gensini评分呈显著负相关关系(r=-0.420,P〈0.05)。结论血浆ghrelin水平越低,冠状动脉病变程度越重,越不稳定。
