Official title
The Ex-Lex Trial: A Randomized Trial Combining Regadenoson With Symptom-Limited Exercise in Patients Undergoing Myocardial Perfusion Imaging
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Not infrequently, a physician is faced with uncertainty regarding the ability of a patient to perform adequate exercise in the noninvasive evaluation of known or suspected coronary artery disease (CAD) by the use of radionuclide stress myocardial perfusion imaging. In selected patients, protocols that combine exercise (either low-level or symptom-limited) with vasodilator stress agents have been found to be safe and effective in both identification of the presence and severity of CAD as well as risk stratification for adverse cardiac outcome. However, currently utilized combined stress protocols have drawbacks. Further refinement of combined stress protocols would potentially lead to more appropriate stress protocol selection for patients while enhancing laboratory efficiency. The purpose of this prospective, randomized study will be to evaluate the relative merits of combining regadenoson with symptom-limited exercise in patients clinically-referred for vasodilator-exercise stress myocardial perfusion imaging for the assessment of known or suspected CAD. It is hypothesized that combining regadenoson with symptom-limited exercise is a safe and feasible stress testing modality which is non-inferior to that which combines symptom-limited exercise with dipyridamole.
