Coronary Artery Disease Clinical Trial
Official title:
The Impact of Routine Administration of Aminophylline Following Regadenoson According to the ASSUAGE Protocol on the Accuracy of Regadenoson Stress Myocardial Perfusion Imaging: A Single-Blinded Cross-Over Clinical Trial
The investigators developed a modified regadenoson nuclear stress test of the heart that incorporates an aminophylline injection following regadenoson (The ASSUAGE protocol). The modified (ASSUAGE) protocol has been associated with fewer side effects and was better tolerated by patients. This study will investigate whether the modified regadenoson stress protocol (ASSUAGE) produces blood flow pattern to the heart similar to that of a standard regadenoson stress protocol. In proven to be the case, the ASSUAGE protocol has the potential to be used on a wide scale instead of the current standard protocol.
Patients who had regadenoson stress nuclear stress test of the heart will be invited to return to undergo a modified nuclear stress using the modified (ASSUAGE) protocol. Images from the original scan will be compared to those from the second scan to determine whether the blood flow pattern is similar between the two scans. ;
