ABSTRACT
Objective To evaluate and compare the therapetic effectiveness among intravenous rt-PA thrombolysis, thrombolysis plus delayed intracoronary stenting and delayed intracoronary stenting for acute myocardial infarction (AMI) using 99 [KG*2/3]Tcm-MIBI myocardial SPECT imaging. Methods Ninty-five cases of AMI were divided into three groups which were the thrombolysis group (n=31), thrombolysis plus delayed stenting group (n=30) and the delayed stenting group (n=34). 99 [KG*2/3]Tcm-MIBI myocardial SPECT imaging was performed 3 weeks after thrombolysis therapy or 1 week after intracoronary stenting.The left ventricular myocardium was divided into 16 segments for evaluation. The score of myocardial 99 [KG*2/3]Tcm-MIBI uptake were analyzed semiquantitatively and the total score of myocardial 99 [KG*2/3]Tcm-MIBI uptake was calculated. Results The scores of the 3 groups were 28.4?7.5, 19.4?6.2 and 27.3?7.2 respectively. Significant difference was shown in the thrombolysis plus delayed stenting group compared with the thrombolysis and the delayed stenting group (t=7.2, t=6.9, P0.05). Conclusion 99 Tcm-MIBI myocardial SPECT imaging has been proved to be an objective parameter for evaluating the therapeutic effectiveness of the various treatments of AMI. Thrombolysis plus delayed stenting seems to be more effective than thrombolysis and delayed stenting. On the other hand, thrombolysis and delayed stenting show similar effect in the treatment of AMI in the study.
