Anti-gravity Treadmill Exercise in Stress Myocardial Perfusion Imaging

This study will test the hypothesis that the anti-gravity treadmill can be safely used in stress nuclear myocardial perfusion imaging in patients unable to perform conventional treadmill exercise. This will be foundational evidence on which to consider a larger clinical trial to show that the anti-gravity treadmill improves diagnostic specificity across all cardiovascular stress testing modalities including treadmill-alone, exercise stress echocardiogram, exercise SPECT as well as having implications for cardiac PET and MRI in the future.
