Comparison of Dobutamine and Regadenoson Stress Cardiac Magnetic Resonance (MR)

Stopped early · Early Phase 1

Conditions studied: Coronary Artery Disease, Asthma, Chronic Obstructive Pulmonary Disease (COPD), Angina

In brief

The goal of this research is to determine the utility of Regadenoson (Lexiscan)for use as an imaging agent with cardiac MR. If found useful, it will help us establish a protocol for regadenoson stress MR perfusion (Regadenoson stress test with cardiac MR).The investigators will compare regadenoson with dobutamine so each participant will undergo two studies. A cardiac MR stress test with regadenoson and with dobutamine. The investigators participants will include patients with history of COPD and Asthma, so it will also help us determine feasibility of Regadenoson in these patient's subgroups.
