Purpose

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.

Primary Outcome Measures:

Duration of procedures [ Time Frame: 1 day ]
To compare the time involved during pharmacologic stress testing using regadenoson versus intravenous dobutamine in individuals with moderate to severe chronic obstructive pulmonary disease (COPD)or asthma.

Secondary Outcome Measures:

Ease of Administration of regadenoson versus intravenous dobutamine. [ Time Frame: 1 day ]
To compare the ease of administration of regadenoson verses intravenous dobutamine during pharmacologic stress testin in individuals with moderate to severe chronic obstructive pulmonary disease (COPD) or asthma.


Estimated Enrollment:	40
Study Start Date:	January 2009
Study Completion Date:	March 2011
Primary Completion Date:	December 2010 (Final data collection date for primary outcome measure)

Arms	Assigned Interventions
Active Comparator: A Arm A will get Dobutamine Stress test with cardiac MR (CMR). Both arms will then cross over to the other arm to get the second test. So each participant will undergo two types of testing.	Drug: Regadenoson, Dobutamine Cross-over design in which each participant will receive regadenoson 0.4mg (5ml) one time bolus dose at one visit and dobutamine infusion (as per protocol to achieve a target heart rate of 85% of predicted for age) at another visit. Other Name: Lexiscan
Active Comparator: B Arm B will get Regadenoson stress test with CMR. Both arms will then cross over to the other arm to get the second test. So each participant will undergo two types of testing.	Drug: Regadenoson, Dobutamine Cross-over design in which each participant will receive regadenoson 0.4mg (5ml) one time bolus dose at one visit and dobutamine infusion (as per protocol to achieve a target heart rate of 85% of predicted for age) at another visit. Other Name: Lexiscan
