Long-term prognostic implications of myocardial perfusion imaging in octogenarians: an all-comer, cohort study.

Purpose: Evaluation of the long-term prognostic value of myocardial perfusion imaging (MPI) in octogenarians.

Methods: Six hundred and twenty-nine octogenarians [51% previous myocardial infarction (MI) or revascularization] who underwent single-isotope MPI (78% Tl, 22% Tc-tetrofosmin) with exercise (38% Bruce, 2% leg ergometry) or pharmacologic (58% adenosine, 2% dobutamine) stress were studied. All patients had LVEF determined by echocardiography within 1 month from MPI.
