[Myocardial viability in a single-vessel disease: the role of a dobutamine stress echocardiography].

Objective: To investigate a group of patients that have a significant lesion in a single-vessel and to demonstrate whether or not the sensitivity and specificity of a dobutamine stress echocardiography (DSE) was valuable in the evaluation of myocardial viability for these patients.

Methods: Twenty patients who had undergone percutaneous transluminal coronary angioplasty (PTCA) were studied. This group was evaluated 2 to 7 days (3.
