Comparison of Tc-99m sestamibi perfusion imaging and echocardiography using an arbutamine infusion for the detection of coronary artery disease.
Arbutamine, a synthetic catecholamine, coupled with a closed-loop, computerized delivery system was evaluated in conjunction with technetium-99m sestamibi scintigraphy and echocardiography for the detection of coronary artery disease. Concordance between the imaging methods was 68%, with a similar sensitivity for coronary disease using echocardiography (78%) and technetium-99m sestamibi (76%), although more arbutamine-induced ischemia was noted with perfusion imaging.
