Abstract:
Objective: To study clinical application value of dobutamine stress echocardiography (DSE) and nitroglycerin stress single photon emission computed tomography (SPECT) for evaluation of restenosis after percutaneous coronary intervention (PCI). Methods: A total of 39 patients after PCI were examined by DSE and SPECT one week before coronary angiography (CAG). Dose incremental program of dobutamine included five levels：5μg•kg-1•min-1, 10μg• kg-1• min-1, 20μg•kg-1•min-1, 30μg•kg-1•min-1, 40μg•kg-1•min-1, and each level maintained for three minutes. Sensitivity, specificity and accuracy of DSE and SPECT were determined according to CAG examined result and examined results were compared between DSE and SPECT. Results: Compared with CAG, SPECT and DSE were no significant differences （P>0.05）in sensitivity (83.3% vs. 75.0%) and accuracy (71.8% vs. 87.2%) for evaluating restenosis after PCI, but compared with SPECT, DSE possessed higher specificity (66.7% vs. 92.6%). Conclusions: Dobutamine stress echocardiography is accurate, and its specificity is better than that of SPECT for evaluating restenosis after percutaneous coronary intervention.
