Objective: To verify the sensitivity, specificity and diagnostic accuracy of dobutamine stress echocardiogram (DSE) when assessing the functional status of coronary grafts: sufficient (SUF) or insufficient (INS).
Methods: We carried out a prospective, observational study which included 25 patients submitted to coronary artery bypass grafting (CABG). The DSE and the coronary angiography were performed before the CABG and three months after the CABG.
