摘要
目的：定量分析急性心肌梗死面积与心功能的关系。材料和方法：初发急性穿壁心肌梗死患者，再通组１５例，平均年龄５７．７岁，未通组１９例，平均年龄６１．７，在发病早期和发病３周行ＳＰＥＣＴ显像，并于发病３周行核素左心室造影测量心肌缺血范围和ＬＶＥＦ。结果：再通组第２次心肌显像心肌缺损范围显著小于第１次显像，未通组两次心肌显像，心肌缺损范围无显著差别，两组病例第２次心肌显像，再通组心肌缺损范围显著小于未通组，而ＬＶＥＦ显著高于未通组第２次心肌显像，心肌缺损范围与ＬＶＥＦ呈负相关性。结论：早期血管再通可缩小心肌梗死面积，心肌梗死面积与左室射血分数有负相关性。
Purpose: In order to evaluate the correlation between the size of perfusion defect and the ejection fraction (EF), a study suing 99mTc-MIBI myocardial imaging and gated cardic blood pool imaging was performed in cases of acute myocardial infarction. Materials and Method: Early (before treatment) and late (after three weeks) myocardial perfusion imaging were performed in 34 AMI patients. After late imaging the gated blood pool imaging was performed. All the patients were devided into the reperfused group and the nonreperfusion group. Result: The size of perfusion defect in the final imaging was smaller in the reperfused group than in the nonreperfusion group. While the ejection fraction (EF) in the reperfused patients was significantly greater than that in the nonreperfusion patients. There was a significant reverse correlation between the xize of the final perfusion defect and the resting EF. Conclusion: Early reperfusion is effective for decreasing the size of AMI. There was a significant reverse correlation between the size of AMI and ejection fraction.
