Abstract：Objective To analyze the guidance value of dual-radionuclide myocardial perfusion imaging image by using 99Tcm-methoxyisobutylisonitrile(MIBI)/18F-fluoro-deoxyglucose(FDG) single photon emission computed tomography(SPECT) on delayed percutaneous coronary intervention in patients with acute myocardial infarction.Methods Forty-nine consecutive patients with acute myocardial infarction undergoing cornory artery angiography (CAG) was divided into group A(PCI surgey) (n=25) and group B(drug therapy) (n=24).Myocardial viability was assessed by 99Tcm-MIBI/18F-FDG Myocardial SPECT inpre-procedue.There were 31 patients with viable myocardium segement and 18 patients with nonviable myocardium segement in infracted area.Cardiac events and resting heart echocardiography were assessed pre-procedure, the first and third month post-procedure respectively in all patients.Results ①During the following-up in the first or third month, LVEF were unchanged in nonviable myocardium group undergoing not only PCI but also medicine treatment(P>0.05).②In the third month post-procedure, LVEF in viable myocardium group undergoing PCI (59.61±11.59)% increased significantly compared with pre-proceduer (51.00±11.50)% and medicine treatment (50.62±11.77)% (P<0.05).However, LVEF in viable myocardium group undergoing medicine treatment was unchanged in the first and third month post-procedure(P>0.05).Conclusion Myocardial viability is assessed by hybrid 99Tcm-MIBI SPECT/18F-FDG SPECT in patients with AMI after delayed PCI, which can predict ventricular function recovery and is helpful to decision making in the treatment strategy.
