Increased Detection of Viable Myocardium Using Myocardial Perfusion Analysis With Dobutamine Stress Echocardiography
in Patients with Resting Wall Motion Abnormalities.
All patients underwent both treadmill-exercise stress testing and dobutamine stress echocardiography
Before and after undergoing TMR with the carbon-dioxide (CO2) Heart Laser System, 11 patients were evaluated by the Duke physicians with a technique known as dobutamine stress echocardiography
, in which the drug dobutamine places a temporary stress on the heart similar to that caused by exercise.

Dobutamine stress echocardiography
was used in 83% of the patients, and the patients who were remaining were stressed on a treadmill.
The abstract Effects of Transmyocardial Laser Revascularization on Regional Left Ventricular Function and Contractile Reserve presented by doctors from Rush Presbyterian Medical Center states, "Resting and low- dose dobutamine stress echocardiography
were performed pre- and three months post- Heart Laser Revascularization in nine patients.
The role of dobutamine stress echocardiography
in early diagnosis of cardiac toxicity in long-term survivors of asymptomatic children treated with anthracycline
SAN DIEGO -- An abnormal dobutamine stress echocardiography
study is an independent predictor of long-term mortality in patients with diabetes, Nithima Chaowalit, M.
The sensitivity of dobutamine induced SND was 7% for significant RCA lesion, specificity was 92% and the overall diagnostic accuracy was 65%, these results according to them showed that SND is a relatively common during dobutamine stress echocardiography
but its importance as a marker of significant RCA lesion was limited due to the high incidence of false positive results (2).
