摘要
目的 :探讨心肌梗塞后血浆脑钠素 (BNP)浓度与左心室重构间的关系。  方法 :用左心室造影投影系统计算出心肌梗塞急性期及恢复期左心室容积指标。用放射免疫法测定急性期及恢复期血浆 BNP浓度 ,并根据左心室容积指标分组 ,左心室容积增加率 >2 0 %为左心室重构组 ,否则为非重构组。  结果 :重构组恢复期左心室舒张末期及收缩末期容积均显著高于非重构组 (P<0 .0 0 1) ,亦显著高于本组急性期左心室容积 (P<0 .0 0 1)。重构组急性期血浆 BNP浓度明显高于非重构组 (入院即刻、入院后 2 4、48、72小时的组间比较分别为 P<0 .0 1,P<0 .0 1,P<0 .0 0 1,P<0 .0 0 1) ;恢复期血浆 BNP浓度重构组较非重构组的增加更为明显 (P<0 .0 0 0 1)。重构组的血浆 BNP浓度与恢复期左心室容积及左心室容积变化量之间存在密切相关。  结论 :血浆 BNP浓度在急性心肌梗塞后发生左心室重构的患者中显著升高 ,并与左心室重构的程度之间存在密切的相关性。它对心肌梗塞预后的预测价值值得探讨。
