چکیده
|
Exercise is the aha/acc guideline-recommended stress modality for myocardial perfusion imaging, but many patients are unable to exercise to target heart rate on a conventional treadmill. we examined the feasibility and safety of stress imaging using an anti-gravity treadmill in patients with perceived poor exercise capacity. 49 patients were recruited for stress testing by anti-gravity treadmill (n = 29) or to a regadenoson control group (n = 20). seventeen anti-gravity test patients (59%) reached target heart rate obviating the need for a pharmacologic stress agent. adverse effects of the anti-gravity treadmill were limited to minor muscle aches in 5 subjects. stress myocardial perfusion image quality judged by 3 blinded readers on a 5-point scale was comparable for the anti-gravity treadmill (4.30 ± sd 0.87) vs pharmacologic stress (4.28 ± sd 0.66). stress testing using an anti-gravity treadmill is feasible and help some patients safely achieve target heart rate.
