Abstract Objective: To investigate the value of fluorodeoxyglucose(18F-FDG) myocardial metabolic imaging combined with 99mTc-MIBI myocardial perfusion imaging in evaluating the Uygur's myocardial infarction and to investigate the effect of surviving myocardium after percutaneous coronary intervention(PCI) on cardiac function in Uygur patients with myocardial infarction. Methods: 78 cases of Uygur patients diagnosed with myocardial infarction, including 40 males and 38 females, aged 45 to 72 years, mean age 51±14 years old. All patients were confirmed by coronary angiography at least one coronary artery occlusion, all patients underwent 99mTc-MIBI myocardial perfusion imaging and 18F-FDG myocardial metabolism imaging before PCI. According to the results of dual-nuclide imaging, the patients were divided into myocardial survival group and no myocardial survival group. Left ventricular ejection fraction(LVEF) and left ventricular short axis shortening(LVFS) were compared between the two groups before and after operation. Results: 78 patients with Uygur heart disease were examined by echocardiography before and after PCI. In the myocardial survival group(41 patients), LVEF was 42.21±6.79 before operation, and the LVEF value increased to 48.21±5.68(P<0.01) after operation; LVFS value increased from 15.97±4.46 to 26.68±7.34, P<0.01; The myocardial function got improved significantly. In the no myocardial survival group, the LVEF value was 41.31±3.84, the postoperative LVEF was 42.13±3.65, P<0.01, the LVFS was 16.64±5.79, the postoperative LVFS was 18.51±3.75, P<0.01; the cardiac function got poor improvement, the difference between before and after surgery was not statistically significant. Conclusion: 99mTc-MIBI myocardial perfusion combined with 18F-FDG myocardial metabolism can effectively detect the viable myocardium of Uygur patients with myocardial infarction, so that patients with viable myocardium have improved their cardiac function after PCI. Therefore, dual-nuclide myocardial imaging has clinical guidance value for PCI in Uygur patients with myocardial infarction.
