急性心肌梗塞TXB_2变化与^（99m）Tc－MIBI心肌显像缺损区范围的关系

Correlation between TXB2 and radioactive defect area acute myocardial infarction

探讨了急性心肌梗塞（ＡＭＩ）病人的血浆ＴＸＢ２变化与９９ｍＴｃ－甲氧基异丁基异腈（ＭＩＢＩ）心肌显像缺损区范围的关系，发现ＡＭＩ患者发病后２４小时内血浆ＴＸＢ２明显升高。并与放射性缺损区范围呈高度相关，ｒ＝０．８５，Ｐ＜０．０１．这对于估测心肌梗塞预后的价值有待进一步探讨．

Abstract The correlation between plasma TXB_2 and radioactive defect area (RAD) in patients with acute myocardial infarction (AMI) was studied.TXB_2 was measured by radioimmunoassay and area of radioactive defect by myocardial perfusion tomographic imaging.The results showed that TXB_2 increased significantly within 24 hours after AMI,and there was a high positive correlation between the level of TXB_2 and RAD,r=0.85, P<0.01.It was worthwhile to further explore the value of this method in evaluating prognosis of patients with AMI.
