What is the purpose of exercise technetium-99m sestamibi tomography for cardiac risk stratification?
Exercise technetium-99m sestamibi tomography is used for cardiac risk stratification of patients with stable chest pain. It is used to help predict cardiovascular death in men undergoing noninvasive evaluation for coronary artery disease. It can also be used to help determine the extent and severity of myocardial hypoperfusion, which can then be used as a predictor of prognosis in patients with suspected coronary artery disease.
