急性ST段抬高心肌梗死患者血清Ⅲ型前胶原氨基端肽与心室重构的关系

目的:观察急性ST段抬高心肌梗死(STEMI)患者血清Ⅲ型前胶原氨基端肽(PⅢNP)水平与心室重构和预后的关系。方法:100例STEMI患者入选,ELISA法测定入CCU即刻和发病第7天血清中PⅢNP含量。于发病第(7±2)天和6个月时行超声心动图检查,6个月复查超声△LVEDVI增加≥20%为重构组,△LVEDVI增加<20%为非重构组。结果:第7天时,STEMI患者血清PⅢNP浓度均明显高于入院水平[(7.95±3.61)ng/m1 vs(4.18±1.83)ng/ml,P<0.001],急诊PCI患者血清PⅢNP浓度明显低于未行急诊PCI者[(7.02±2.97)ng/ml vs(11.07±3.82)ng/ml,P<0.001]。6个月随访时左心室重构发生率为27.96%,急诊PCI患者22.78%,未急诊干预者57.14%,两组间有显著差异P=0.008。重构组患者第7天PⅢNP浓度明显高于非重构组[(10.82±3.91)ng/ml vs(6.86±2.83)ng/ml,P<0.001]。结论:STEMI患者第7天血清PⅢNP水平与半年时心室重构的发生密切相关。第7天血清PⅢNP水平升高者心室重构率高,预后差。
