Assessment of myocardial viability with dobutamine stress echocardiography versus ~(99m)Tc single photon emission computed tomography / 中华超声影像学杂志

ABSTRACT

Objective To assess the value of dobutamine stress echocardiography (DSE) in predicting myocardial viability by comparing with single photon emission computed tomography(SPECT).Methods Taking improvement of ventricular wall motion as a standard,fifteen patients undergone percutaneous coronary artery intervention(PCI) were detected by DSE and SPECT respectively,comparing their accuracy in predicting myocardial viability.Results By DSE, difference of the sensitivity and negative forecasting value was remarkable between peak dose stage and low dose stage,comparing with DSE,SPECT had the highest sensitivity and the lowest distinctivity.Conclusions The two techniques have their own advantages and disadvantages in predicting myocardial viability,but DSE is more practical.
