Answer

Advantages to stress echocardiography are that it is a faster test to perform than a nuclear stress test because delayed images are obtained much sooner. It has no associated radiation exposure. It is less costly than nuclear stress testing, and therefore performs well on cost analysis studies. The test can be more readily performed in an office setting.

In a meta-analysis that included data from 24 studies, Fleischmann et al found that exercise echocardiography had a sensitivity of 85% and a specificity of 77% when compared with coronary angiography. The results were felt to be similar to those for single photon emission computed tomography (SPECT) imaging. [25]
