摘　　要：目的 :探讨血运重建术后的急性心肌梗塞患者2 0 1Tl与12 3 I BMIPP同步心肌显像预测左室功能改善的临床意义。材料与方法 :对 30例急性期接受PTCA的心肌梗塞患者进行2 0 1Tl与12 3 I BMIPP同步心肌显像。急性期及恢复期进行心血池显像测定左心室射血分数。结果 :根据Tl/BMIPP核素分布类型将患者分为T型分离组和B型分离组。B组12 3 I BMIPP负荷像与再分布像的缺损积分显著高于本组2 0 1Tl的缺损积分 ;亦显著高于T组12 3 I BMIPP的缺损积分。B组恢复期左室射血分数较急性期显著增加 ,且其LVEF改善度与Tl/BMIPP分离度之间存在显著的正相关。结论 :2 0 1Tl与12 3 I BMIPP同步心肌显像在预测心肌梗塞患者左室功能改善具有临床实用价值。Purpose: To demonstrate the value of 201 Tl and 123 I BMIPP dual isotope SPECT in evaluating improvement of left ventricular function in the patients with acute myocardial infarction. Materials and Methods: Thirty patients who had received PTCA within 1 week after onset of acute myocardial infarction were recruited for the study. 201 Tl and 123 I BMIPP dual isotope SPECT were performed within 39～45 d after the onset. LVEF was also calculated in the acute and convalescent phases. Results: In one group, RD scores of 123 I BMIPP SPECT in both stress and redistribution images were significantly higher than that of 201 Tl SPECT. They were also significantly higher than that of the second group. In the first group, LVEF in convalescent phase was higher than that in acute phase (P<0.01), and the improvement of LVEF significantly correlated with the difference of scores between Tl and BMIPP (P<0.01). Conclusion: 201 Tl and 123 I BMIPP dual isotope SPECT are useful in predicting improvement of left ventricular function after acute myocardial infarction.
