【摘要】 目的 探讨急性心肌梗死患者溶栓治疗过程中血浆B型利钠肽(BNP)及D-二聚体(DD)的临床表达。方法 200例急性心肌梗死患者, 其中小面积梗死(Ⅰ组)118例, 中面积梗死(Ⅱ组)54例, 大面积梗死(Ⅲ组)28例, 采用全自动免疫荧光分析方法测定三组患者血浆DD、BNP含量, 对照彩色多普勒确定的心肌梗死面积大小进行比较, 讨论其关联性。结果 梗死面积越大, 患者BNP、DD水平越高(Ⅰ组<Ⅱ组<Ⅲ组), 差异具有统计学意义(P<0.05)。结论 心肌梗死面积与BNP结果有明显关联, 动态监测DD水平, 可以作为溶栓治疗的效果评价。

【Abstract】 Objective To investigate clinical expression of plasma B-type natriuretic peptide (BNP) and D-dimer (DD) during thrombolysis in acute myocardial infarction patients. Methods Among 200 acute myocardial infarction patients, there were 118 cases with small area of infarction (group Ⅰ), 54 cases with moderate area of infarction (group Ⅱ), and 28 cases with large area of infarction (group Ⅲ). Contents of plasma DD and BNP in the three groups were detected by full-automatic immunofluorescence assay. Comparison was made on diagnosed infraction are by color Doppler ultrasound for correlation evaluation. Results Levels of BNP and DD increased along with large infarction area (group Ⅰ< group Ⅱ< group Ⅲ), and the difference had statistical significance (P<0.05). Conclusion Area of myocardial infarction is closely correlated with BNP content, and dynamic monitoring of DD content can show evaluation of thrombolysis effect.

心肌梗死是严重威胁人类健康的重大疾病, 该病近年呈上升趋势, 早期诊断是救治成功的关键。利钠肽是近年发现的一类具有多种生物学活性和临床应用价值的多肽, 尤其是BNP, 是心功能不全时最敏感和特异的指标之一。BNP已被欧洲心脏病协会(ESC)、美国心脏协会(AHA)、美国心脏病学会(ACC)、美国临床生化学院(NACB)及我国心血管病学会纳入临床心力衰竭的诊断标准和指南中[1-6];心肌梗死往往伴有不同程度的纤溶亢进, 而DD又是反映纤溶亢进的敏感指标, 已经证明:DD是纤维蛋白单体经活化因子交联后, 再经纤溶酶水解产生的一种特异性降解产物, 是一个特异性的纤溶过程标记物, 其来源于纤溶酶溶解的交联纤维蛋白凝块。1971年, Wilson等首先将纤维蛋白降解产物用于诊断肺静脉栓塞, 开启了运用纤维蛋白降解产物诊断并治疗深部静脉栓塞的先河[7-10]。作者对来本院就诊的200例急性心肌梗死患者进行了BNP及DD的动态监测, 结合彩色多普勒来确定患者心肌梗死面积大小, 旨在探讨BNP联合DD测定与心肌梗死面积大小的关联性, 现报告如下。……
