Why the study?
Does dobutamine echocardiography compared to quantitative rest-redistribution 201Tl tomography better predict recovery of function after revascularization in patients with stable coronary disease and regional dysfunction?

In myocardial hibernation, dobutamine echocardiography is more specific but less sensitive than quantitative thallium scintigraphy for predicting functional recovery after revascularization.
No takes yet. Share an insight, caveat, or question.
Dobutamine echocardiography may aid viability testing via higher specificity; leaves open optimal modality selection for revascularization decisions.
Qureshi et al. (1997) studied this question.
