Abstract

Abstract

Objective To analyze the diagnostic value of Coronary Computed tomography angiography （CCTA）combined with rest CT myocardial perfusion （CT-MPI） in patients after percutaneous coronary intervention （PCI）. Methods Twenty-two patients after PCI were selected to receive CCTA combined with resting PCT to evaluate the patency and myocardial perfusion to evaluate the effect of CCTA combined with resting CTMP on myocardial ischemia after PCI. Results CCTA showed restenosis in 4 of 25 stents, combined examination showed that 10 cases had abnormal myocardial perfusion and 12 cases had no abnormal myocardial perfusion, the same as that of echocardiography; the accuracy of CTMPI and combined examination was 90% and 100%, combined examination can improve the detection of myocardial ischemia and evaluate the stenosis in the stent. Conclusion CCTA combined with CTMPI is more effective in the diagnosis of mysocardial ischemia after PCI. We can get the data of stent and myocardial perfusion, which improves the diagnostic value of patients after PCI.
