摘　　要：目的 探讨急性心肌梗死（AMI）患者血清脑钠肽（BNP）水平与近期预后的临床关系.方法 将2008年1月至12月于我科住院的急性ST段抬高型心肌梗死患者99例按治疗方案分为直接经皮冠状动脉介入治疗（PCI）组61例,保守组38例.观察两组患者入院即刻、入院1 d、入院7 d 时血清BNP浓度的变化,并记录患者30 d内的主要不良心脏事件（MACE）.结果 入院即刻、1 d时两组患者血清BNP浓度差异无统计学意义（P＞0.05）.入院7 d时PCI组患者血清BNP浓度低于保守组（P＜0.01）,PCI组主要不良心脏事件发生率低于保守组（P＜0.05）.对AMI者梗死后30 d主要不良心脏事件的危险因素进行logistic回归分析,显示患者入院7 d时血清BNP浓度是最主要的不良心脏事件预测因子（OR=1.026,95%CI 1.014-1.038,P＜0.01）.所有患者30 d随访期间,发生主要不良心脏事件的患者入院7 d时血清BNP浓度高于未发生者（P＜0.01）.结论 AMI患者入院7 d时的血清BNP水平可以作为判断近期预后的指标.Objective To investigate relationship between serum level of brain natriuretic peptide （BNP）and short-term prognosis in patients with acute myocardial infarction（AMI）.Methods Ninetynine patients with AMl with elevated S-T segment in electrocardiogram admitted to the department of cardiology,the Fourth Hospital of Jilin University,Changchun during January to December 2008 were divided into two groups.one with percutaneous transluminal coronary angioplasty（PTCA）or pereutaneous coronary intervention（PCI）（61 eases）and the other without PTCA（38 cases）as controls.Their serum levels of BNP were measured at admission, and one day and seven days after admission,respectively,and their main adverse cardiac events（MACE）were followed-up and recorded for 30 days.Results No significant differenee in serum BNP level between the patients at admission and one day after admission was found（P〈0.01）.Seven days after admission,serum BNP level in PCI group was significantly lower than that in controls（P〈0.01）,and occurrence of MACE was significantly lower in PCI group than that in controls（P〈0.05）.Logistic regression analysis indicated that serum BNP level in PCI group seven days after admission was the uppermost predictor for MACE in patients with AMI in one month after onset（OR=1.026,95%CI 1.014-1.038,P〈0.01）.Serum BNP level was significantly higher in patients with MACE seven days after admission than that in those without it（P〈0.01）during 30-day followup.Conclusion Serum level of BNP seven days after admission is associated with their short-term prognosisfor patients with AMI.
