Stress-rest ~(99m)Tc-MIBI myocardial perfusion SPECT for functional assessment of percutaneous coronary intervention / 解放军医学杂志

ABSTRACT

Objective To evaluate the value of stress-rest 99mTc-MIBI myocardial perfusion single photon emission computed tomography (SPECT) for the operation of percutaneous coronary intervention. Methods Fifty-two patients with coronary heart disease underwent stress-rest 99mTc-MIBI myocardial perfusion SPECT before and 1-2 weeks after the performance of percutaneous coronary intervention (PCI). Results It was found that after the performance of PCI, the exercise time (6.13?0.27), metabolic equivalent (7.19?0.27) and heart rate-systolic pressure cross product (RPP) (200.17?5.17) were significantly increased than that before PCI (4.29?0.26, 5.19?0.27 and 72.81?6.59, respectively, P
