摘要
目的:本研究旨在通过分析急性 ST 段抬高心肌梗死患者基础及经皮冠状动脉介入治疗(PCI)后 B 型利钠肽(BNP)水平,探讨 PCI 治疗对 BNP 水平的影响及 BNP 与近期预后的关系。方法:入选急性 ST 段抬高心肌梗死患者103例,依据入院后治疗方式分为6小时内 PCI 组40例,6~12小时 PCI 组33例,药物治疗组30例。所有患者于入院即刻、发病48小时及7天时从外周静脉中留取血样测定 BNP,分别比较不同时间不同治疗方式之间 BNP 的差别,以及 BNP 与1个月时心功能的关系。所有患者均无心力衰竭、陈旧性心肌梗死及肺部、肾脏疾病史。结果:①3组患者入院即刻基础 BNP 水平无统计学意义(P>0.05)。发病48小时、7天时6小时内 PCI 组 BNP 水平较6~12小时 PCI 组均明显下降,差异均有统计学意义(P<0.05~0.01),6小时内 PCI 组较药物治疗组亦明显下降,差异均有统计学意义(P<0.05~0.01);发病48小时6~12小时 PCI 组 BNP 水平与药物治疗组相比较差异无统计学意义(P>0.05)。发病7天时6~12小时 PCI 组 BNP 水平与药物治疗组比显著下降,差异有统计学意义(P<0.05)。②发病7天时的 BNP 水平与1个月时心功能左心室射血分数有明显相关性(r=-0.722,P<0.001),与 Tei 指数呈正相关(r=0.582,P<0.001)。③随访时发生心力衰竭、心绞痛及心血管事件的患者回顾发病7天时 BNP 水平明显高于未发生者(P<0.05~0.001)。结论:在急性 ST 段抬高心肌梗死患者中,发病7天时 BNP 水平与近期心功能显著相关,对近期心血管事件的发生有一定预测作用,早期 PCI 可以显著降低发病7天时 BNP 水平及降低心血管事件的发生率。
Objective:To evaluate prognosis of patients with ST elevation myocardial infarction(STEMI) by examining B-type natriuretic peptide (BNP) levels after pereutaneous coronary intervention(PCI). Methods : A total of 103 eonsecutive patients with STEMI were enrolled. They were divided into 3 groups : Group 1 ( received PCI within 6 hours from the onset ,n = 40 ) ; Group 2 ( received PCI within 6-12 hours from the onset, n = 33 ) ; Group3 ( received medication, n = 30). Blood samples for BNP were drawn at admission, 48 hours and 7days from the onset respectively. All patients were followed up at 1 month by eehocardiography. No patients had the history of heart failure, old myoeardial infaretion, lung and kidney disease. Results :(1)BNP levels were significantly lower at 7 days from the onset in Group 1 and Group 2 than those in Group 3 (204 pg/ml vs 436 pg/ml vs 698 pg/ml, P 〈 0. 05 ). (2)BNP levels at 7 days from the onset showed a significant negative correlation with LVEF( r = - 0. 722, P 〈 0. 001 ) and a positive correlation with Tei in 1 month ( r = 0. 582, P 〈 0. 001 ). (3)By 3 months follow up, BNP levels were significantly increased at 7 days of onset in patients to whom eardiac events happened than not happend(792 pg/inl vs 301 pg/ml, P 〈0. 001 ). Incidence of heart failure was decreased in Group 1. Conclusion: Elevations in BNP at 7 days from the onset were associated with abnormal LVEF and adverse clinical outcome after STEMI. BNP levels and incidence of cardiac events were decreased in patients received early PCI.
