血浆B型利钠肽水平对非ST段抬高性急性冠脉综合征患者预后的预测价值

目的评估血浆B型利钠肽(BNP)水平对非ST段抬高性急性冠脉综合征(NSTE-ACS)患者预后的预测价值。方法入选NSTE-ACS患者180例,所有患者于发病第24小时采用免疫荧光法测定血浆BNP水平,根据24 hBNP水平将患者分为血浆BNP≥80 ng/L组与BNP<80 ng/L组。对所有患者随访6个月,观察早期BNP水平与随访6个月主要不良心血管事件发生的关系。结果随访6个月,180例患者中有42例(23%)患者发生主要不良心血管事件,血浆BNP≥80 ng/L组患者主要不良心血管事件发生率明显高于BNP<80 ng/L组患者(P=0.003),在校正了年龄、性别、高血压病、糖尿病、高脂血症、吸烟及左室射血分数等影响预后的危险因素后,NSTE-ACS患者入院早期血浆BNP水平≥80 ng/L与随访6个月发生主要不良心血管事件显著相关[校正RR=3.625,95%CI(1.505～8.731),P=0.004]。结论 NSTE-ACS患者早期BNP水平增高有助于评价NSTE-ACS患者6个月主要不良心血管事件的发生,可应用于危险分层的评估。

Relation of plasma brain natriuretic peptide levels on admission to prognosis in patients with non-ST segment elevation acute coronary syndrome

Objective To investigate the relation between brain natriuretic peptide(BNP) levels on the first 24 hours after the onset of non-ST segment elevation acute coronary syndrome and the major adverse cardiovascular events(MACEs-ACS) 6 months later.MethodsConsecutive 180 patients with non-ST segment elevation acute coronary syndrome were studied,BNP plasma concentration levels were measured by fluorescence immunoassay at 24 hour from onset,patients were divided into two groups according to plasma BNP level,group...
