Coronary Artery Disease Clinical Trial
Official title:
Integrated Dual Exercise and Lexiscan PET: IDEAL PET
This is a single-center study of subjects undergoing clinically indicated heart scans for evaluation of known or suspected heart disease. We will also include 10 healthy subjects without known heart disease. We would like to study stress testing of the heart using exercise and a medication called regadenoson. Imaging of the heart will be performed.
Regadenoson is stress agent approved by the FDA for use with myocardial perfusion imaging
with technetium-99m single photon emission computed tomography (SPECT) in patients that are
unable to exercise adequately. We would like to study Regadenoson in conjunction with
Exercise Rubidium-82 positron emission tomography myocardial perfusion imaging (PET MPI).
Regadenoson is not approved by FDA for use with Rubidium-82 PET MPI. Also, we would like to
study a novel stress protocol of Regadenoson combined with symptom limited exercise stress
(not FDA approved).
The objectives of this study are to assess the tolerability and safety of combined symptom
limited exercise stress test with Lexiscan (Lexercise PET) compared to Lexiscan alone
(Lexiscan PET), to assess image quality of Lexercise compared to Lexiscan PET and to compare
relative and absolute myocardial perfusion imaging with Lexercise compared to Lexiscan PET to
identify CAD.
