[摘要]目的 探讨血浆NT-proBNP预测急性非ST段抬高心肌梗死患者血管急性闭塞的价值。方法 选取2014年4月～2015年4月在本院就诊的60例急性非ST段抬高心肌梗死患者作为研究对象，按照冠状动脉造影结果分为非闭塞组(30例)和闭塞组(30例)。两组均行急诊PCI，给予阿司匹林、硝酸酯和他汀类调脂药物。比较两组的NT-proBNP、cTnI水平及相关指标变化情况。结果 闭塞组的血清NT-proBNP、cTnI水平显著高于非闭塞组，差异有统计学意义(P<0.05)。闭塞组的A、DT值均大于非闭塞组，E、LVEF值小于非闭塞组，差异有统计学意义(P<0.05)。结论 血浆NT-proBNP在急性非ST段抬高心肌梗死患者血管急性闭塞预测中具有重要意义。

    [Abstract]Objective To explore the value of plasma NT-proBNP on predicting acute vascular occlusion in myocardial infarction patients with acute non-ST segment elevation.Methods 60 myocardial infarction patients with acute non-ST segment elevation from April 2014 to April 2015 in our hospital were selected and divided into the non-occlusion group (30 cases) and the occlusion group (30 cases) according to outcomes of coronary arteriography.Both groups were performed with percutaneous coronary intervention (PCI) as well as aspirin ......
